Up to Five Times Higher Costs for Those with Rare Diseases

By studying medical and insurance records indicates health care costs for people with a rare disease, researchers have found that these have been underestimated and are three to five times greater than the costs for people without a rare disease.

The findings, appearing in the Orphanet Journal of Rare Diseases, provides new evidence of the impact rare diseases could have on public health, suggesting that medical costs for individuals with rare diseases are on par with those for cancer and heart failure.  

“There needs to be greater public awareness of the large and growing medical footprint of rare diseases in society,” said senior author Anne Pariser, MD, director of the NCATS Office of Rare Diseases Research. “Only about 10% of rare diseases have an FDA-approved therapy for their treatment. The findings underscore an urgent need for more research, and earlier and more accurate diagnoses of and interventions for these disorders.”

Most of the 7000 to 10 000 known rare diseases disproportionately affect children, adolescents and young adults. Individually, most rare diseases might affect only a few hundred to a few thousand people around the world. Rare diseases however are collectively common, affecting an estimated 4% of the world’s population. Many of these diseases have a genetic cause, are serious or life-threatening and are hard to diagnose and treat.

The pilot study used International Classification of Diseases (ICD) codes, which designate a disease diagnosis and other methods, to determine those individuals with rare diseases and their direct medical costs for 14 rare diseases in four health care systems compared to non-rare disease patients of a similar age.

The 14 rare diseases represented a diverse set of disorders differing in prevalence, organ systems affected, age of onset, clinical course, and availability of an approved treatment or specific ICD code. These rare diseases include sickle cell disease, muscular dystrophy and eosinophilic esophagitis.

The analysis showed wide variations of rare diseases prevalence in the different health care systems, possibly due in part to geographic differences, as well as the use of public versus private insurance, which may include different patient group representation. Some genetic diseases can also have a higher prevalence in certain regions, due to demographic make-up.

With the Eversana health care system database, the cost per patient per year (PPPY) for those with a rare disease, ranged from $8 812 to $140 044 for rare diseases patients compared to $5862 for those without a rare disease. The NCATS data indicated PPPY costs ranging from $4859 to $18 994 for rare diseases patients versus $2211 for those without a rare disease.

Using patient medical records, the researchers also traced the diagnostic journeys of four people with a rare disease, including two individuals who had a form of Batten disease, an inherited neurological disorder, and two others with cystic fibrosis. These journeys provided detailed descriptions of direct medical costs, such as for hospitalisations and procedures for these diseases, and provided insights into patient clinical management before and after disease diagnosis.

Analysis of medical records also revealed that rare diseases patients often shared commanilities in symptoms (eg, seizures, infections, and developmental delay) and characteristics, which could aid in earlier diagnosis and treatmen. As many receive a rare disease diagnosis at a young age and because most rare diseases are serious conditions, rare disease patients are likely to require hospital time and incur greater medical expenses over a lifetime.

Such commonalities among rare disease patients could point to the potential use of machine learning techniques on health care system databases to improve diagnoses, said study co-author Joni L. Rutter, PhD, NCATS Acting Director.

The researchers would also like to determine whether these methodologies could be scaled to thousands of other known rare diseases.

“Ultimately, to improve the lives of people with rare diseases,” said Dr Rutter, “we need to find innovative ways, including new technologies, to help shorten the lengthy diagnostic odysseys so many patients and families experience and make more treatments available faster.”

Rare Diseases in South Africa: A Neglected Topic

An article in Spotlight examines the challenges faced by South Africans with rare diseases.

A rare disease is a health condition affecting a small number of people compared with other diseases commonly identified in the population. According to the World Health Organization (WHO), there are between 5000 and 8000 known rare diseases worldwide, affecting an estimated 400 million people.

According to the advocacy group Rare Disease South Africa (RDSA), about 3.6 million people in SA have a rare disease. In South Africa, the ability to diagnose a rare disease is hindered by a lack of capacity and resources, according to research, putting the time to diagnosis for rare diseases in general higher than the estimated 5.5 to 7.5 years in high-income countries.
“There is still low recognition of genetic disorders among specialists. And when they are recognised, testing remains expensive and requires sophisticated levels of training which are relatively limited,” says Prof Karen Fieggen, a medical geneticist at the University of Cape Town (UCT).

According to her, costs, skills, training, and human resource factors are all barriers to effective testing and diagnosis. But she says the rationale to build an effective system is solid.

“We have capable people and expertise to build this system, but until you invest in it, it won’t be big enough to be self-sustaining,” she says.

Prof Fieggen acknowledges that resources are stretched in the public sector, where specialists who carry out genetic testing for rare diseases must meet the needs of a larger part of the population. However, she notes, “there’s no guarantee you’re better off in the private sector”.

“There are very few genetic referral options, and none of the medical geneticists are kept in work full time,” she says. In Cape Town, for example, she says that all patients seeking genetic testing had to come to the private sector until recently. “We have the capacity to train seven specialists a year, but posts aren’t available for them to take,” she says.

At one per 4.5 million population, available medical geneticists in the public healthcare sector fall far short of the 21 per 2 million recommended by the WHO. These services are also spread unevenly through the country. The country’s heavy burden of HIV and TB is partly responsible for this lack of coverage.

While healthcare training must focus on these public health needs, Prof Fieggen says rare diseases need a sensible approach. “It doesn’t help to throw huge resources at something that will have minimal management impact,” she says. “But the way in which rare diseases have been relatively ignored isn’t constructive.”

Helping the recognition of rare diseases and referral pathways in physician training may make a difference. “One thing that could be instilled in training is to recognise that if things are atypical in their presentation, there should be a discussion with a referral centre,” says Associate Professor Ian Ross, a senior consultant endocrinologist at UCT and Groote Schuur Hospital.

Only 2.5-5% of rare diseases have approved treatments, some of which are prohibitively expensive.

The most expensive drug in the world is Zolgensma (generic name onasemnogene abeparvovec), a once-off treatment costing a mind-blowing USD $2.1 million (R 30m). Used to treat inherited spinal muscular atrophy, where infants with the condition are unlikely to see their second birthday. However, even this is available through the UK’s National Health Service, which struck a deal to bring prices down.

Du Plessis says these drugs are not on the essential medicines list because of the small group of patients they would serve. “The essential medicines list is dedicated to treatments that are procured in large numbers. Rare diseases will never be mass-market drugs.”

Such drugs can be purchased by hospital pharmacists so they can be available at a certain hospital, making for a haphazard situation.
To help address this inequality, RDSA held a Rare Disease Symposium on 25 August, inviting feedback on a draft policy framework from various medical sector and political stakeholders.

The framework has a definition for rare disease in SA, namely a condition affecting one in 2000 people or fewer. It also recommends including rare diseases in the NHI benefit package. The NHI bill also includes a Benefits Advisory Committee, which will determine what diseases get coverage,

However, Dr Nicolas Crisp, Acting Director General for Health, said that the NHI would not ring-fence funding. As medical insurance will be done away with, it will be crucial to secure funding for those extremely expensive drugs unaffordable to the private sector.
