Disappointing Colorectal Cancer Screening Results with Colonoscopy

A randomised study of northern European data shows that colonoscopy screening reduces the risk of colorectal cancer by 18%, much smaller than experts previously assumed. The results of the study appear in the New England Journal of Medicine.

Colonoscopy may not even perform better than screening with faecal tests, said Louise Emilsson, docent at the Department of Medical Epidemiology and Biostatistics, Karolinska Institutet, and national Swedish principal investigator of the study.

Prior to the publication of this study, experts assumed that screening with colonoscopy had significantly better effect than screening with faecal tests. Faecal tests are used in colorectal cancer screening programs in many countries, and other countries have introduced screening with colonoscopy based on the fact that researchers via observational and modelling studies estimated that up to nine out of ten cases of colorectal cancer could be prevented with a colonoscopy screening. With faecal tests, similar models has estimated the effect to be two to three out of ten.

In the NordICC study, the researchers investigated the extent to which colonoscopy screening actually prevents colorectal cancer. Overall, 1.2% of those randomised to no screening were diagnosed with colon cancer during ten years, compared to 0.98% in those offered screening.

This translates to an 18% reduced risk of colorectal cancer among the participants who were offered colonoscopy screening. Furthermore, 455 colonoscopies were required to prevent one single case of colorectal cancer. Colonoscopy is fairly invasive and costly procedure, involving preparation, bowel prep with laxatives, and a 30-45 minute examination of the bowel with a camera inserted via the rectum. The figure of 455 procedures to prevent one case of cancer is certainly disappointing, Louise Emilsson concluded.

Colorectal cancer mortality was also found to be lower than expected in the NordICC study. Only three in a thousand died of the disease within ten years, regardless of whether they were offered screening or not, and thus, there was no significant difference between the groups in terms of mortality. The low mortality rate is however encouraging and likely caused by significantly improved treatment options over the past ten years.

Maternity Wards at Dora Nginza Hospital ‘Chaotic’ as Nurses Down Tools

Services at the Dora Nginza Hospital in Gqeberha, Eastern Cape are under strain as the nurse’s strike entered its second day on Friday. The striking nurses are demanding that management provide more beds and staff to the maternity wards, among other demands. They claim that their previous engagements with the health department have been fruitless.

On Thursday, some patients were moved to another hospital. Dora Nginza Hospital is the centre for maternal and paediatric care for the western part of the Eastern Cape.

A pregnant woman at the hospital described the maternity ward as “chaotic”.

“Heavily pregnant women were crying for help that was not coming. Many people are sleeping on the cold floor and there is a smell of blood in the ward. The few nurses there are overwhelmed,” she said.

Vuyo Nodlawu, regional chairperson of the Democratic Nursing Organisation of South Africa (DENOSA), told GroundUp that the maternity wards do not have enough beds and resources to cope with the influx of patients since Monday. “Patients, be it prenatal or postnatal, did not have beds to sleep on. The situation has been getting worse, to the extent that patients who had given birth were removed from beds to accommodate those in labour,” he said.

Nodlawu said the hospital’s management had told medical practitioners to stop admitting patients if there were no more beds available or until the matter was resolved. “However, the doctors continued to admit patients. Nurses then decided to allocate all available beds within the maternal department to everyone who didn’t have a bed,” said Nodlawu.

A meeting was called between the maternal directorate from the head office and the hospital but it was unsuccessful.

Mzikazi Nkatha, provincial deputy secretary of the National Union of Public Service and Allied Workers (NUPSAW)’s, said, “Nurses are saying enough is enough. They can’t continue as normal when patients have to lie on the floor and not on hospital beds. This is also an overwhelming number of patients and not enough health providers to care for them.”

Health department spokesperson Yonela Dekeda said union leaders have not been willing to negotiate with officials sent by management. Dekeda said plans to “decongest” Dora Nginza Hospital are underway, with emergency cases being referred to Port Elizabeth Provincial Hospital.

She said a team from other hospitals across the district were deployed to assist. The team included Anaesthetics, Obstetrics , Gynaecology, Paediatrics, Neonatology, Nursing and non-clinical support services.

“The designated ward and theatre at the Provincial Hospital has been staffed and equipped with the relevant equipment and medication. The Emergency Medical Services is also part of the response team and will coordinate patient transfers between facilities,” she said.

Dekeda said the department considers the nurses’ action as an unprotected strike. “These essential workers are refusing to engage with senior management nor do they want to return to work. The department takes this very seriously and the administrative and legal remedies at our disposal are being deployed,” she said.

DENOSA’s deputy regional chairperson Vuyo Dlanga has vowed that nurses would continue their action until provincial government officials meet them to resolve the issues.
