Charlotte Maxeke Repairs Make Progress, but Doubts Remain

2023 is the crunch year to complete the restoration of the fire-damaged sections of Charlotte Maxeke Johannesburg Academic Hospital, but one month in, it has not been plain sailing.

There are doubts over timeframes, the quality of workmanship, compliance, and effective project management. Added to this are deepening concerns that theft and suspected sabotage continue and that HR red tape and inefficiencies are standing in the way of getting the right people into 774 vacant posts that need to be filled to meet the high demand for healthcare services.

According to Gauteng Department of Health’s head of communication, Motalatale Modiba, the province is on track to meet its December 2023 deadline to complete repair work. There is a separate deadline for 2026 to complete fire safety compliance throughout the hospital.

Scramble for parking persists

January kicked off with what should have been the reopening of parking bays on the hospital campus. The parking levels were among the worst affected areas in the fire that broke out on 16 April 2021. Delays in getting parking areas reopened have had dire knock-on effects on the efficient running of the hospital. Staff and visitors have had to scramble to find parking on the streets around the hospital. This adds to traffic congestion and jammed-up appointment schedules even as the hospital is trying to play catch-up after healthcare services were disrupted by COVID and the fire. Added to this, there have been reports of theft from motor vehicles as well as muggings and assaults of doctors and nurses having to make their way to and from their cars.

Before the fire, the hospital had 1700 parking bays. Since the fire, only 229 have been accessible on the hospital campus and another 400 in sites around the hospital – it’s a shortfall of about 1000 parking bays.

Modiba told Spotlight at the beginning of February, The construction of the temporary access ramp to level P3 is 100% complete. The only outstanding thing is the enrolment of the traffic management system to ensure a greater flow of vehicles into the parking, manage different parking zones, and vehicle access. The P3 parking bays will be available for usage soon.”

‘Criminal syndicates’

But DA spokesperson for health in the province, Jack Bloom says after his own site visit in January that continued delays to reopen this section is “gross incompetence that is causing misery as staff and patients hunt for parking every day and some sick people have to walk a long way from where they’ve found parking”.

“It’s not a great start for the year,” says Bloom. He says delays are being made worse by the higher stages of rolling blackouts that have hit the country, even though the hospital campus is exempt from loadshedding.

“Another issue is that we still haven’t been able to crack down on criminal syndicates operating at our hospitals. I believe what we’re seeing in the media now is only skimming the surface of widespread corruption in the system,” he says.

Insiders at Charlotte Maxeke have again raised alarms over ongoing theft that they say smacks of sabotage. According to them, the current situation is that cables and piping that run in-between hospital floors have been stolen or destroyed, resulting in disrupted oxygen flow that is fed to wards in Block 5 of the hospital. Block 5, houses, among others, the transplant unit.

Last year, the National Department of Health confirmed to Spotlight that vandalism and theft were rife. Investigations resulted in three officials in the Department of Infrastructure and Development being arrested in connection with these crimes.

Modiba did not respond to follow-up questions on how theft, vandalism, and sabotage are being dealt with by the provincial health department.

Repair work “on track”

Still, Modiba insists that the province is on track to meet both its 2023 and 2026 deadlines. Modiba however, also didn’t respond to a follow-up question on what compliance protocols will be followed in the three-year gap till fire safety compliance is expected to be completed.

It was fire safety compliance being flouted (including non-functioning fire doors, hose couplings that were stolen or broken, and no floor plan available for firefighters when they arrived on site) that led to the April 21 fire spreading and causing the extensive damage it did.

The repair bill now carries a price tag of R1.16 billion. According to Modiba, just over a billion of this will come from National Treasury, with around R146 million from donors making up the remainder.

The restoration work plan has also had to be adjusted in the past few months. An initial approach to work on fire compliance in multiple hospital blocks at a time was rejected by clinicians because it would be too disruptive for patient care.

“Decanting will now happen on a block-by-block basis with compliance work estimated to be between six to eight months per block. Services will keep rotating within the facility while contractors work from one area to another,” Modiba says.

He also tells Spotlight that the emergency unit which only reopened in May last year – and at the time only for referral patients – is now fully functioning. “All specialities are now present at the facility; there are no longer services that are being remotely rendered at other facilities,” he adds.

Modiba says that the hospital currently runs 1024 beds compared to the pre-fire status of 1138 beds. This comprises 1068 public beds and 70 Folateng beds. Folateng is the private ward within the hospital. There are 108 ICU and high-care beds and between 60 000 and 70 000 outpatients per month.

Meeting demands amid HR issues

Professor Adam Mahomed, head of the Department of Internal Medicine at the hospital, says meeting these massive demands when whole units and blocks have been out of commission has been a feat of adapting by doctors and nurses who have optimised ward space and found ways to repurpose parts of the hospital.

“Wards that used to fit 20 to 24 beds, we now have turned into wards that fit 32 beds,” he says.

Mahomed says it’s not optimal and amounts to trying to function in an overburdened state, especially with gross staff shortages. He says they expect the healthcare need to increase from the current numbers to having to run 1 400 beds in the hospital.

“We are seeing more people and sicker people coming through the doors because, during the COVID years, many people were not coming for healthcare or taking their chronic meds. We are also still playing catch up in oncology and surgery.”

Mahomed singles out inefficiencies in the hospital’s human resources department as the biggest stumbling block. He is calling for an independent audit and investigation into how human resources at Charlotte Maxeke is being run.

According to him, there are mounting questions around irregularities of why positions are not being filled timeously, or seemingly deliberately delayed and not just as a tactic to wait for budgets to refresh with the new financial year in April.

Some examples of “silly paperwork”, he says, are sessional doctors who have worked in the public sector previously being asked to produce matric certificates from 40 years ago. Other doctors have been asked to produce police clearance certificates, while others are asked to have proof of citizenship issued by the Department of Home Affairs.

According to Modiba, Charlotte Maxeke Hospital has 5334 approved posts and 774 vacancies currently. Of the 774 vacant positions, 253 vacancies are in administration and support, 40 for allied workers, 124 in medical, and 357 in nursing.

Mahomed says, “We need to have staff that will be able to accommodate 1400 beds and we need to have increased resources allocated for a hospital that is already over-burdened. We need to get HR to stop with the red tape, silly paperwork, and bureaucracies. “Bureaucracy is hampering us from getting actual resources to the people – HR bureaucracy is killing people. Politicians and management are still running healthcare when they should be taking input from those who are on the ground.”

Patients ‘Don’t Need to be Checked for Everything’, Recommendation Says

Blood samples

Commonly ordered tests can provide early warning of underlying disease, but could also create unnecessary risks of false positive results, provoking anxiety in the patient, wasted time and money and risks of invasive testing.

Therefore, to combat commonly ordered – but not always necessary – procedures and tests, the Society of General Internal Medicine (SGIM) on Tuesday released its revised list of recommendations on five primary care procedures and tests that patients and physicians should question.

Northwestern University’s Dr Jeffrey A. Linder and David Liss, who have previously published research on the benefits of primary care checkups, helped revise the list.

For instance, the age-old idea of getting an annual physical exam with “routine blood tests” from a primary care doctor is a misconception because a person’s age and other risk factors should influence how frequently they should see their doctor, Linder said.

“We often have patients come in asking us to ‘check me for everything,’ but this is a potentially anxiety-provoking, dangerous thing for patients because the more testing we do, the more stuff we find, and the more we need to follow up,” said Linder, chief of the division of general internal medicine at Northwestern University Feinberg School of Medicine and a Northwestern Medicine physician. “In someone who is asymptomatic, an ‘abnormality’ is much more likely to be a false positive or of no clinical significance than for us to catch early disease.

“False positives can expose patients to all of the anxiety, costs, hassle and time commitment, and danger from sometimes invasive testing, with a very low likelihood that it is going to improve their health.”

This isn’t to say nobody should get a checkup every year. For instance, patients who have overdue preventive services, rarely see their primary care physician, have low self-rated health and/or are aged 65 or older should get an annual checkup, the scientists said.

The newly revised list is part of SGIM’s Choosing Wisely campaign, which is an initiative of the American Board of Internal Medicine Foundation. SGIM members originally selected the topics in 2013 and later updated the list in 2017.

The list generated controversy when it was first developed in 2013, recalls Linder.

“The list was widely misinterpreted as ‘specialty society says you don’t need to see your doctor,’ but that was not what it said,” Linder said.

Time and downstream financial costs also are issues of these commonly ordered but oftentimes unnecessary tests and procedures, Liss said.

“Patients and care teams often spend valuable time on low-value checkups that could have been devoted to high-need patients,” said Liss, research associate professor of general internal medicine at Feinberg. “There also is the overall increase in costs to the health system. And even if annual checkups are covered by most insurance, patients often have copays for services like blood draws and other diagnostic tests.”

The revised list was developed after months of careful consideration and review, using the most current evidence about management and treatment options. Linder and Liss served as ad hoc members of the SGIM’s Choosing Wisely Working Group.

Here are the five recommendations, based on a review of the most recent studies in the field:

  1. Don’t recommend daily home glucose monitoring in patients with Type 2 diabetes mellitus not using insulin.
  2. Don’t perform routine annual checkups unless patients are likely to benefit; the frequency of checkups should be based on individual risk factors and preferences. During checkups, don’t conduct comprehensive physical exams or routine lab testing.
  3. Don’t perform routine pre-operative testing before low-risk surgical procedures.
  4. Don’t recommend cancer screening in adults with life expectancy of less than 10 years.
  5. Don’t place, or leave in place, peripherally inserted central catheters for patient or provider convenience.

Ceiling Vents Above COVID Patient Beds Provide Optimal Protection for HCWs

Researchers have modelled the transmission of SARS-CoV-2-containing aerosol particles within an isolation room, and found the optimal layout to reduce the exposure risk for health care workers. In Physics of Fluids, Wu et al. share their findings and guidance for isolation rooms. Their work focuses on the location of the room’s air extractor (air outlet) and filtration rates, the location of the patient’s bed, and the health and safety of the health care workers (HCWs) within the area.

The researchers modelled an isolation room at the Royal Brompton Hospital in London, with the aim of finding out the optimal room layout to reduce the risk of infection for health care staff.

“We modelled the virus transport and spreading processes and considered the effect of the temperature and humidity on the virus decay,” said Fangxin Fang, of Imperial College London. “We also modelled fluid and turbulence dynamics in our study, and explored the spatial distribution of virus, velocity field, and humidity under different air exchange rates and extractor locations.”

They discovered that the area of highest risk of infection is above a patient’s bed at a height of 0.7 to 2 metres, where the highest concentration of SARS-CoV-2 virus is found. After the virus is expelled from a patient’s mouth, it gets driven vertically by buoyancy and wind forces within the room.

Based on the group’s findings, the optimal layout for an isolation room to minimise infection risk is to use a ceiling extractor with an air exchange rate of 10 air changes per hour. The study focused on an isolation room within a hospital and its numerical results are limited due to the omission of droplet evaporation and particle matters, the researchers point out.

Now, the group plans to include evaporation and particle processes in models of a standard hospital patient room, intensive care unit, and waiting room.

“Further work will also focus on artificial intelligence-based surrogate modelling for rapid simulations, uncertainty analysis, and optimal control of ventilation systems as well as efficient energy use,” said Fang.

FBI Disrupts Cybercrime Group Which Extorted Hospitals

The Hive ransomware group that has targeted more than 1500 victims in over 80 countries around the world, including hospitals, has been disrupted in a months-long campaign against, the US Justice Department has announced.

Hive ransomware attacks have caused major disruptions in victim daily operations around the world and hindered responses to the COVID pandemic. In one case, a hospital attacked by Hive ransomware had to fall back to pen and paper to treat existing patients and could not take new admissions shortly after the attack. 

The Justice Department revealed that the FBI had penetrated Hive’s computer network and captured its decryption keys, which were then offered to victims around the world. This saved them $130 million in ransom they would have had to otherwise pay to get their networks back.

Finally, the department announced that, in coordination with German and Dutch law enforcement, it has seized control of the servers and websites that Hive uses to communicate with its members, disrupting Hive’s ability to attack and extort victims.

Since June 2021, the Hive ransomware group has targeted more than 1500 victims around the world and received over $100 million in ransom payments.  

Hive used a ransomware-as-a-service (RaaS) model featuring administrators, and affiliates. RaaS is a subscription-based model where the administrators develop an easy-to-use ransomware strain and then recruit affiliates to deploy the ransomware against victims. Affiliates identified targets and deployed this readymade malicious software to attack victims and then earned a percentage of each successful ransom payment.

Hive actors used a double-extortion model of attack: before encrypting the victim’s system, the affiliate would steal sensitive data. The affiliate then sought a ransom for both the decryption key necessary to decrypt the victim’s system and a promise to not publish the stolen data – usually the most sensitive, such as hospital patient data. After a victim pays, the affiliates and administrators split the ransom 80/20. Victims who do not pay on the Hive Leak Site. After Consulate Health Care was unable to pay the ransom, since its insurance did not cover such cyber crimes, Hive posted 550GB of personally identifiable information on its patients and employees online.

Inpatient Blood Draws are Often Performed During Sleep Hours

The sleep of hospitalised patients may be often interrupted due to non-urgent blood draws, according to findings from a Yale study published in JAMA. This may be exacerbating sleep deprivation, and putting them at greater risk for health events later on.

In an analysis of more than 5 million non-urgent blood draws collected at Yale New Haven Hospital from 2016 to 2019, a team of researchers found that a high proportion of them occurred during a three-hour window in the early morning.

“We found that nearly four in 10 of total daily blood draws were performed between 4am and 7am,” said César Caraballo-Cordovez, MD, a postdoctoral associate at Yale Center for Outcomes Research and Evaluation (CORE) and co-lead author of the study. “Importantly, we found that this occurred across patients with different sociodemographic characteristics, including older individuals who are at highest risk of adverse health events from sleep deprivation.”

Although early morning blood draws are often considered necessary to inform decisions during morning medical rounds, the authors suggest that sleep interruptions may increase the risk of delirium and other adverse events. “Patients who were recently hospitalised experience a period of generalised risk for myriad adverse health events, a condition named posthospital syndrome,” added Dr Caraballo-Cordovez. “The stress that patients experience during the hospitalisation – including stress from sleep deprivation – is a key contributor to this period of increased risk.”

“This is not an issue at just one hospital,” said Harlan M. Krumholz, MD, SM, professor of medicine and public health at Yale and CORE director. “Our findings reflect an aspect of how inpatient hospital care is being delivered in modern medicine. A more patient-centered care would limit nonurgent tests during sleep hours. However, these early morning blood draws are often considered necessary to make decisions during rounds.”

“We need to re-design our process to protect patients’ sleep, but major changes in our practice must be informed by solid studies that demonstrate the efficacy of strategies to do so without untoward effects,” added Krumholz.

Health Care Integration Sees Ballooning Costs for Minor Care Benefit

Over the past few decades, health care integration has absorbed physician practices and hospitals into large health systems, a practice which was heralded as the way to cut health care costs and boosting quality of care.

But integrated health systems appear to be failing on both fronts, according to the results of a new US study published in JAMA. For patients in health systems, care is only marginally improved while costs are significantly higher compared to those at independent practices or hospitals.

In the US, health systems have grown exponentially in size and market share through mergers and acquisitions of physician practices and hospitals and the joining of separate health systems.

Proponents of consolidation have argued over the years that physicians and hospitals working together in integrated, coordinated systems provide better patients care while being more efficient than independent physician practices and hospitals. This would drive quality of care up while keeping spending steady and even driving costs down.

“One of the key arguments for hospital mergers and practice acquisition was that health systems would deliver better-value care for patients. This study provides the most comprehensive evidence yet that this isn’t happening,” said study first author Nancy Beaulieu at Harvard Medical School.

Today, these systems are responsible for a large proportion of the medical care delivered in the US, some employing thousands of physicians. But despite their impact on population health and the economy, little is known about the actual performance of integrated health organisations, the study authors noted.

A lack of detailed data on performance and scale is a key obstacle. The current analysis is believed to be the first comprehensive national study to compare outcomes between patients receiving care within health systems and outside of them, including patients with private insurance as well as traditional Medicare, which is the US health insurance system for those over 65 or which certain disabilities or conditions. 

The analysis included a total of 580 health systems, accounting 40% of physicians and 84% of general acute care hospital beds. Academic and large nonprofit systems accounted for a majority of system physicians (80%) and system hospital beds (64%).

System hospitals were larger than hospitals than nonsystem ones, with 67% of system hospitals having more than 100 beds, while only 23% of nonsystem hospitals having more than 100 beds. System physician practices were also more likely to have more than 100 physicians compared with nonsystem practices (74% vs 12%). Integrated systems delivered primary care to 41% of traditional Medicare beneficiaries.

As for quality and cost of care delivered within systems, patients with primary care physicians in health systems reported slightly better satisfaction and overall care experience than patients of independent physicians.

This is the case even though many patients with nonsystem primary care providers also receive some of their care in hospitals or specialist practices that are part of a health system. However, care in systems came at a much higher price, contributing to higher overall spending on health care, the research showed.

Prices for services from physicians and hospitals within health systems were significantly higher than for independent healthcare, the study found. Physician services delivered within health systems cost between 12% and 26% more, compared with independent practices. System-based hospital services cost an average of 31% more than care delivered by independent hospitals.

Small differences in quality combined with large differences in cost of care suggests that health systems have not, on average, realised their potential for better care at equal or lower cost, the researchers said.

Members of the research team have compiled a database from various sources to help characterise these health systems and to link claims data with information on health care providers in and out of health systems. The database, housed at NEBR, will be made available for free to other researchers in the near future.

“There’s no question that large, sophisticated health systems have benefits over independent systems,” said study author David Cutler, Harvard economic professor. “Big systems tend to be less vulnerable to economic downturns and they can provide specialised care that would be difficult to maintain in smaller systems. But the hoped-for cost savings benefits of integrated health systems have not yet materialised.”

Patients Themselves may be the Source of New Strains of HAIs

Despite stringent infection-control efforts around the world, hospital-acquired infections (HAIs)keep on popping up from new strains of bacteria. In Science Translational Medicine, researchers report evidence pointing to an unexpected source of such bacteria: the hospitalised patients themselves.

From experiments with mice, researchers at Washington University School of Medicine in St. Louis discovered that urinary tract infections (UTIs) can arise after sterile tubes, called catheters, are inserted into the urinary tract, even when no bacteria are detectable in the bladder beforehand. Such tubes are commonly used in hospitals to empty the bladders of people undergoing surgery. In the mice, inserting the tubes activated dormant Acinetobacter baumannii bacteria hidden in bladder cells, triggering them to emerge, multiply and cause UTIs, the researchers said.

The findings suggest that screening patients for hidden reservoirs of dangerous bacteria could supplement infection-control efforts and help prevent deadly HAIs.

“You could sterilise the whole hospital, and you would still have new strains of A. baumannii popping up,” said co-senior author Mario Feldman, PhD, a professor of molecular microbiology. “Cleaning is just not enough, and nobody really knows why. This study shows that patients may be unwittingly carrying the bacteria into the hospital themselves, and that has implications for infection control. If someone has a planned surgery and is going to be catheterised, we could try to determine whether the patient is carrying the bacteria and cure that person of it before the surgery. Ideally, that would reduce the chances of developing one of these life-threatening infections.”

The notoriously multidrug-resistant A. baumannii is a major threat to patients, causing many cases of UTIs in people with urinary catheters, pneumonia in people on ventilators, and bloodstream infections in people with central-line catheters into their veins.

The researchers set out to investigate why so many A. baumannii UTIs develop after people receive catheters.

Most UTIs among otherwise healthy people are caused by the bacterium Escherichia coli. Research has shown that E. coli can hide out in bladder cells for months after a UTI seems to have been cured, and then re-emerge to cause another infection.

The researchers investigated whether A. baumannii can hide inside cells like E. coli can. They studied mice with UTIs caused by A. baumannii. They used mice with weakened immune systems because, like people, healthy mice can fight off A. baumannii.

Once the infections had resolved and no bacteria were detected in the mice’s urine for two months, the researchers inserted catheters into the mice’s urinary tracts with a sterile technique. Within 24 hours, about half of the mice developed UTIs caused by the same strain of A. baumannii as the initial infection.

“The bacteria must have been there all along, hiding inside bladder cells until the catheter was introduced,” said co-senior author Scott J. Hultgren, PhD, a professor and expert on UTIs. “Catheterisation induces inflammation, and inflammation causes the reservoir to activate, and the infection blooms.”

Since A. baumannii rarely causes symptoms in otherwise healthy people, many people who carry the bacteria may never know they’re infected, the researchers said. According to the researchers’ literature search, 2% of healthy people carry A. baumannii in their urine.

“I wouldn’t put much weight on the precise percentage, but I think we can say with certainty that some percentage of the population is walking around with A. baumannii,” Feldman said. “As long as they’re basically healthy, it doesn’t cause any problems, but once they’re hospitalised, it’s a different matter. This changes how we think about infection control. We can start considering how to check if patients already have Acinetobacter before they receive certain types of treatment; how we can get rid of it; and if other bacteria that cause deadly outbreaks in hospitals, such as Klebsiella, hide in the body in the same way. That’s what we’re working on figuring out now.”

Magnesium Sulfate Reduces Cerebral Palsy Risk by a Third

Preterm baby

Premature birth is the main cause of brain injury and cerebral palsy in babies. Evidence shows that babies can be protected from brain injury by giving magnesium sulfate to women who are at risk of premature birth, reducing the risk of cerebral palsy by a third. From a societal and lifetime perspective, the health gains and cost savings associated with the preventative treatment generated a net monetary benefit of £866 per preterm baby, according to an evaluation published in Archives of Disease in Childhood.

The prevention of cerebral palsy in pre-term labour (PReCePT) programme was developed in 2014 and aimed to support all maternity units in England to increase the use of magnesium sulfate in premature births. It was then piloted in five NHS trusts in the West of England, and this pilot was evaluated by the NIHR Applied Research Collaboration West (NIHR ARC West). It has since been rolled out across England via the AHSN Network as a national programme.

The evaluation of the national programme, also led by NIHR ARC West, found that PReCePT was both effective and cost-effective. The researchers looked at data from the UK National Neonatal Research Database for the year before and year after PReCePT was implemented in maternity units in England.

While use of magnesium sulfate had been increasing before, the study showed that PReCePT was able to accelerate uptake. It increased by 6.3 percentage points on average across all maternity units in England during the first year, over and above the increase that would be expected over time as the practice spread organically. After also adjusting for variations in when maternity units started the programme, the increase in use of magnesium sulfate was 9.5 percentage points. By May 2020, on average 86.4% of eligible mothers were receiving magnesium sulfate.

The researchers also estimated that the programme’s first year could be associated with a lifetime saving to society of £3 million. This accounts for the costs of the programme, administering the treatment and of cerebral palsy to society over a lifetime, and the associated health gains of avoiding cases. This is across all the extra babies the programme helped get access to the treatment during the first year.

In the five pilot sites, the improved use of magnesium sulfate has been sustained over the years since PReCePT was implemented. As the programme costs were mostly in the first year of implementation, longer-term national analysis may show that PReCePT is even more cost-effective over a longer period.

John Macleod, NIHR ARC West Director, Professor in Clinical Epidemiology and Primary Care at the University of Bristol and principal investigator of the evaluation, said: “Our in-depth analysis has been able to demonstrate that the PReCePT programme is both effective and cost-effective. The programme has increased uptake of magnesium sulfate, which we know is a cost-effective medicine to prevent cerebral palsy, much more quickly than we could have otherwise expected.

Professor Lucy Chappell, Chief Executive Officer of the National Institute for Health and Care Research, said: “This important study shows the impact of taking a promising intervention that had been shown to work in a research setting and scaling it up across the country. Giving magnesium sulfate to prevent cerebral palsy in premature babies is a simple, inexpensive intervention that can make such a difference to families and the health service. We look forward to seeing ongoing use of magnesium sulfate across our maternity units so that these benefits continue.”

How Well do Doctors Stick to Their Prescriptions?

Photo by Towfiqu Barbhuiya on Unsplash

Following established guidelines about prescription drugs would seem an obvious choice, especially for the professionals that do the prescribing. Yet doctors – and their family members – are less likely than other people to comply with those guidelines, according to a large-scale study published in the American Economic Review: Insights.

This result could be surprising or else prompt a knowing nod. In any case, the finding flies in the face of past scholarly hypotheses. Previously, it was assumed that greater knowledge and easier communication with medical providers leads patients to follow instructions more closely.

The new study is based on over a decade of population-wide data from Sweden and includes suggestive evidence about why doctors and their families may ignore medical advice. Overall, the research shows that the rest of the population adheres to general medication guidelines 54.4% of the time, while doctors and their families lag 3.8% behind that.

“There’s a lot of concern that people don’t understand guidelines, that they’re too complex to follow, that people don’t trust their doctors,” says Amy Finkelstein, a professor in MIT’s Department of Economics. “If that’s the case, you should see the most adherence when you look at patients who are physicians or their close relatives. We were struck to find that the opposite holds, that physicians and their close relatives are less likely to adhere to their own medication guidelines.”

The paper, “A Taste of Their Own Medicine: Guideline Adherence and Access to Expertise,” is The authors are Finkelstein, the John and Jennie S. MacDonald Professor of Economics at MIT; Petra Persson, an assistant professor of economics at Stanford University; Maria Polyakova PhD ’14, an assistant professor of health policy at the Stanford University School of Medicine; and Jesse M. Shapiro, the George Gund Professor of Economics and Business Administration at Harvard University.

Millions of data points

To conduct the study, the scholars examined Swedish administrative data from 2005 through 2016, for 63 prescription drug guidelines. Doctors and their close relatives were selected. All told, the research involved 5 887 471 people to whom at least one of the medication guidelines applied. Of these people, 149 399 were doctors or their close family members.

Using information on prescription drug purchases, hospital visits, and diagnoses, the researchers could see if people were adhering to medication guidelines by examining whether prescription drug decisions matched these patients’ medical circumstances. In the study, six guidelines pertained to antibiotics; 20 involved medication use by the elderly; 20 focused on medication attached to particular diagnoses; and 17 were about prescription drug use during pregnancy.

Some guidelines recommended use of a particular prescription drug, like a preference of narrow-spectrum antibiotics for an infection; other guidelines were about not taking certain medications, such as the recommendation that pregnant women avoid antidepressants.

Out of the 63 guidelines used in the study, doctors and their families followed the standards less often in 41 cases, with the difference being statistically significant 20 times. Doctors and their families followed the guidelines more often in 22 cases, with the difference being statistically significant only three times.

“What we found, which is quite surprising, is that they [physicians] are on average less adherent to guidelines,” says study author Maria Polyakova PhD, an assistant professor of health policy at the Stanford University School of Medicine. “So, in this paper we are also trying to figure out what experts do differently.”

Ruling out other answers

Since doctors and their close relatives adhere to medical guidelines less often than the rest of the population, what exactly explains this phenomenon? While homing in on an answer, the research team examined and rejected several hypotheses.

First, the lower compliance by those with greater access to expertise is unrelated to socioeconomic status. In society overall, there is a link between income and adherence levels, but physicians and their families are an exception to this pattern. As the researchers wrote, special “access to doctors is associated with lower adherence despite, rather than because of, the high socioeconomic status” of those families.

Additionally, the researchers did not find any link between existing health status and adherence. They also studied whether a greater comfort with prescription medication – due to being a doctor or related to one – makes people more likely to take prescription drugs than guidelines recommend. This does not appear to be the case. The lower adherence rates for doctors and their relatives were similar in magnitude whether the guidelines pertained to taking medication or, alternately, not taking medication.

“There are a number of first-order alternative explanations that we could rule out,” Polyakova says.

Resolving a medical mystery

Instead, the researchers believe the answer is that doctors possess “superior information about guidelines” for prescription drugs – and then deploy that information for themselves. In the study, the largest difference in adherence to guidelines is for antibiotics: Doctors and their families are 5.2% less in compliance than everyone else.

Most guidelines in this area recommend starting patients off with “narrow-spectrum” antibiotics, which are more targeted, rather than “broader-spectrum” antibiotics. The latter might be more likely to eradicate an infection, but greater use of them also increases the chances that bacteria will develop resistance to these valuable medications, which can reduce efficacy for other patients. Thus for things like a respiratory tract infection, guidelines call for a more targeted antibiotic first.

The issue, however, is that what is good for the public in the long run – trying more targeted drugs first – may not work well for an individual patient. For this reason, doctors could be more likely to prescribe broader-spectrum antibiotics for themselves and their families.

“From a public-health perspective, what you want to do is kill it [the infection] off with the narrow-spectrum antibiotic,” Finkelstein observes. “But obviously any given patient would want to knock that infection out as quickly as possible.” Therefore, she adds, “You can imagine the reason doctors are less likely to follow the guidelines than other patients is because they … know there’s this wedge between what’s good for them as a patients and what’s good for society.”

Another suggestive piece of data comes from different types of prescription drugs that are typically avoided during pregnancies. For so-called C-Class drugs, where empirical evidence about the dangers of the drugs is slightly weaker, doctors and their families have an adherence rate 2.3 percentage points below other people (meaning, in this case, that they are more likely to take these medications during pregnancy). For so-called D-Class drugs with slightly stronger evidence of side effects, that dropoff is only 1.2 percentage points. Here too, doctors’ expert knowledge may be influencing their actions.

“The results imply that probably what’s going on is that experts have a more nuanced understanding of what is the right course of action for themselves, and how that might be different than what the guidelines suggest,” Polyakova says.

Still, the findings suggest some unresolved tensions in action. It could be, as Polyakova suggests, that guidelines about antibiotics should be more explicit about the public and private tradeoffs involved, providing more transparency for patients. “Maybe it’s better for the guidelines to be transparent and say they recommend this not because it is [always] the best course of action for you, but because it is the best for society,” she says.

Additional research could also aim to identify areas where lower expert adherence with guidelines may be associated with better health outcomes –to see how often doctors have a point, as it were. Or, as the researchers write in the paper, “An important avenue for further research is to identify whether and when nonadherence is in the patient’s best interest.”

Major SAMRC Study Sheds Light on Causes of Disease and Death in SA

Unsafe sex, interpersonal violence, high body mass index (BMI), high systolic blood pressure, and alcohol consumption are the top risk factors for disease and death in South Africa, according to the Second Comparative Risk Assessment (SACRA2) study conducted by the South African Medical Research Council’s Burden of Disease (BOD) Research Unit in collaboration with a long list of researchers. The study was recently published in a series of 15 related articles in the South African Medical Journal.

The study differs from other assessments of what people in South Africa die of in that it focusses on risk factors rather than on the eventual cause of death. This is, for example, why the study considers factors like unsafe sex or high body mass index rather than HIV or diabetes.

According to a related policy brief, the aim of the study was “to quantify the contribution of 18 selected risk factors to identify areas of public health priority”. The idea is that policymakers can use these findings to address the underlying causes of death and disease in South Africa since the identified risk factors are considered to be modifiable.

“We have to reduce the underlying drivers of disease and death if we are to improve the health of South Africans,” said CEO and President of the SAMRC Professor Glenda Gray in a statement. “Knowing that this is possible, should strengthen our resolve to ensure that this is accomplished.”

Causes of lost DALYs

Rather than only looking at what people died of, the researchers estimated the lost disability-adjusted life years (DALYs) associated with various risk factors. The World Health Organization describes DALYs as “a time-based measure that combines years of life lost due to premature mortality (YLLs) and years of life lost due to time lived in states of less than full health, or years of healthy life lost due to disability (YLDs). One DALY represents the loss of the equivalent of one year of full health.”

The researchers calculated the proportion of the total burden of disease (measured as DALYs) that can be attributed to each of the 18 risk factors in South Africa in 2012. Unsafe sex was top of the list at 26.6%, followed by interpersonal violence at 8.5%, high body mass index at 6.9%, high systolic blood pressure at 5.8%, and alcohol consumption at 5.6%. There were some differences by sex, with alcohol consumption, for example, ranking third in males, while it ranked fifth overall.

“Improvements have been observed, in particular, the reductions in the burden attributable to household air pollution and water and sanitation,” read the policy brief. “On the other hand, shifts in cardiometabolic risk factors, particularly the rapid emergence of high fasting plasma glucose accompanied by increases in high systolic blood pressure and high BMI, can be seen as well as the increased impact of ambient air pollution.”

According to project lead and BOD Unit Director Professor Debbie Bradshaw, while unsafe sex and interpersonal violence remained high on South Africa’s risk profile for the study period, non-communicable diseases combined are at an all-time high and are highly likely to overtake unsafe sex and interpersonal violence as causes of death and disease in South Africa.

Findings only up to 2012

The SACRA2 findings cover the period from 2000 to 2012. One reason for it only being published now is that the study required access to a wide variety of data sources. “Each data set had to be evaluated to identify any weaknesses or possible bias so that we can develop a robust understanding [of] the trends in the risk factors. This is a painstaking task, involving a large number of scientists, and means that we have only been able to describe the trends for the period 2000 – 2012,” says Bradshaw.

While robust and more up-to-date estimates would likely only come from the next SACRA study, it seems likely that some of the trends identified in SACRA2 would have continued in the years since 2012. For example, findings from SACRA2 suggest that the burden attributable to unsafe sex peaked in 2006 and has been declining ever since, largely due to the provision of antiretroviral treatment. Evidence from other sources, such as Thembisa, the leading mathematical model of HIV in South Africa, suggests that the decline in HIV-related deaths and the increase in treatment coverage have continued in the years since 2012.

Bradshaw describes unsafe sex as a lack of condom use which leads to sexually transmitted infections (STIs) and the possible transmission of HIV.

“Condom use is very important. If we get rid of unsafe sex, we will see the number of people being infected with HIV and STIs being reduced,” she said. “It is important that these epidemic drivers are not neglected in the push towards meeting the 90-90-90 management targets for 2022 and the 95-95-95 targets by 2030. HIV communication programmes should continue to promote male circumcision and risk awareness in the context of non-marital relationships to prevent HIV transmission.” (The first 90/95 refers to the percentage of people living with HIV who are diagnosed, the second to the percentage of those diagnosed on treatment, and the third to the percentage of those on treatment who are virally suppressed.)

Interpersonal violence declining

As with unsafe sex, the trend with interpersonal violence in South Africa also appears to be downward, although, as Megan Prinsloo, a researcher at the SAMRC, and colleagues highlight in one of the 15 papers, it continues to be a leading public health problem for the country.

The researchers found that between 2000 and 2012, there was a decrease in the death rate associated with interpersonal violence from 100 per 100 000 to 71 per 100 000. There was also a decrease in lost DALYs attributable to interpersonal violence from an estimated 2 million in 2000 to 1.75 million in 2012.

“Further strengthening of existing laws pertaining to interpersonal violence, and other prevention measures are needed to intensify the prevention of violence, particularly gender-based violence,” the researchers wrote.

High BMI and high blood pressure

A high BMI is associated with several cardiovascular diseases, diabetes, and chronic kidney disease, among others. According to one of the SACRA2 papers, high BMI caused around 59 000 deaths in 2012. Over the study period, the burden was higher in males than in females. Type 2 diabetes was the leading cause of death attributable to high BMI in 2012, followed by hypertensive heart disease, haemorrhagic stroke, ischaemic heart disease, and ischaemic stroke.

The researchers found that the average BMI increased between 2000 and 2012 and accounted for a growing proportion of both total deaths and DALYs.

High systolic blood pressure is similarly linked to an increased risk of several conditions, including stroke and heart disease. According to a paper by Beatrice Nojilana, a senior research scientist at the SAMRC, and colleagues, the prevalence of hypertension in people aged 25 and older increased from 2000 to 2012 – 31% to 39% in men and 34% to 40% in women.

But there is some interesting nuance. In both men and women, age-standardised rates for deaths and DALYs associated with raised systolic blood pressure increased between 2000 and 2006 but decreased from 2006 to 2012.

High systolic blood pressure is estimated to have caused around 62 000 deaths in South Africa in 2012. Stroke (haemorrhagic and ischaemic), hypertensive heart disease, and ischaemic heart disease accounted for over 80% of the disease burden attributable to raised systolic blood pressure over the period.

Alcohol abuse

In another SACRA2 paper, Dr Richard Matzopoulos, chief specialist scientist at the SAMRC, and colleagues, point out that alcohol abuse has widespread effects on health and contributes to over 200 health conditions. They write that, although the pattern of heavy episodic drinking independently increases the risk for injuries and transmission of some infectious diseases, long-term average consumption is the fundamental predictor of risk for most conditions.

The researchers used data from 17 population surveys to estimate age- and sex-specific trends in alcohol consumption in the adult population of South Africa between 1998 and 2016. For each survey, they calculated sex- and age-specific estimates of the prevalence of drinkers and the distribution of individuals across consumption categories.

Among males, the prevalence of drinkers was found to have decreased between 1998 and 2009, from 56.2% to 50.6%, but had increased again by 2016. Among females, the prevalence of current drinkers rose slightly from 19% in 1998 to 20% in 2016.

Speaking to Spotlight, Matzopoulos stresses that alcohol abuse puts a heavy burden on the already strained health system. “When you enter the trauma unit at hospitals on weekends, all you can smell is alcohol,” he said.

He says in some of his research he has noted a shift where young females are engaging in heavy drinking and young males are engaging in binge drinking over weekends. “These patterns are alarming because alcohol abuse can lead to unsafe sex, which may lead to the transmission of HIV and STIs. Excessive alcohol use also has an impact on some NCDs and can compromise the immune system of a person who is on ARV treatment,” he said.

Matzopoulos said government can put in place policies such as the restriction of alcohol sales, banning alcohol advertising, and increasing the price of alcohol.
