Universities have an obligation to ensure that their assessments are sound and defendable when they confer degrees for professional qualifications, such as in medicine. Can institutions confidently defend these results and what are the implications if they pass a student who is not competent?

These were some of the questions Prof Hanneke Brits, a family medicine specialist at the Free State Department of Health, as well as the Department of Family Medicine, at the University of the Free State (UFS), addressed during her inaugural lecture on Tuesday (12 August). The UFS, she concluded at the end of her lecture, titled To pass or not to pass: Can we confidently defend the outcome of our assessments? can defend its clinical assessments with the implementation of effective workplace-based assessment and trained examiners. 

 

The implications of passing incompetent students 

According to Prof Brits, who has supervised numerous undergraduate and postgraduate student research projects, she chose this topic because decisions have consequences. She gave an overview of the assessments in the clinical years of the undergraduate medical programme. In so doing, she also answered other questions including what may happen when universities pass students who are not competent and what may happen if they fail competent students. When the university passed a candidate, she said, that candidate may register with a professional body like the Health Professions Council of South Africa to work as a doctor. 

“What are the implications if we fail to fail a student who is not competent? The implications are that patients may suffer if they are treated by an incompetent doctor, which may lead to the doctor running into trouble if it is found that their work is not up to standard. This may further lead the faculty being labelled as poor for training substandard doctors. 

“The throughput rate of the university may go down and the university may not get subsidy for the students. The student must repeat his module with a lot of emotional and financial burden. They public may suffer because there are not enough healthcare professionals to treat them. Therefore, we must get this right,” she said. 

When assessing students, assessors should start at the bottom: students should know, then they should know how, then they should show how and then they must do. All assessments should meet the basic requirements of validity, reliability, fairness, educational impact and feasibility, explains Prof Brits. 

 

Workplace-based training and assessment

During her PhD study, she looked specifically at assessments in the clinical years of the undergraduate medical programme. “It is quite complicated,” said Prof Brits, “to do assessment for professional qualifications as you need to obey to the rules and regulations of the Department of Education, the Department of Health, the Health Professions Council of South Africa, the Colleges of Medicine of South Africa because they are our examining body, as well as our own university rules and international assessment guidelines and best practices.” 

She compiled a framework to measure what they do at the UFS and found that the decision reliability was excellent – meaning the students that passed during the year passed at the end of the year and those that failed, failed. The reliability of some of the methods used for the final assessment was not good, however, if more assessments with supplementary exams were included, it was better. 

The conclusion of her study was that the UFS mostly complied with the regulations of the regulatory bodies. The recommendation from this study was to implement workplace-based assessment (WBA) to improve both the validity and reliability of assessments and to make it more defendable. Prof Brits explained that WBA is where students get regular assessment and feedback while they work and receive training in hospitals or clinics. “For example, the student is seeing a patient in the emergency department who was stabbed with a knife on his hand. Is the student able to assess the severity, can the student manage the wound and what about follow-up? 

“The advantage of WBA is that we train in real life situations and manage conditions that occur commonly. In real life situations, students use many senses while learning, e.g., seeing, hearing, touching, smelling, which all enhance knowledge retention. It is important that students receive feedback and that we document these encounters. To ensure a holistic approach to the management of patients we use Entrustable Professional Activities or EPAs – something that I can trust a person to do. It is a combination of knowledge, skills and attitudes.”

To tan or not to tan: a burning issue
2009-12-08

 Prof. Werner Sinclair

“Some evidence exists which implies that sunscreens could indeed be responsible for the dramatic rise in the incidence of melanoma over the past three decades, the period during which the use of sunscreens became very popular,” says Prof. Werner Sinclair, Head of the Department of Dermatology at the University of the Free State. His inaugural lecture was on the topic Sunscreens – Curse or Blessing?

Prof. Sinclair says the use of sunscreen preparations is widely advocated as a measure to prevent acute sunburn, chronic sun damage and resultant premature skin aging as well as skin malignancies, including malignant melanoma. There is inconclusive evidence to prove that these preparations do indeed achieve all of these claims. The question is whether these preparations are doing more harm than good?

He says the incidence of skin cancer is rising dramatically and these tumours are induced mostly by the ultra-violet rays.

Of the UV light that reaches the earth 90-95% belongs to the UVA fraction. UVC is normally filtered out by the ozone layer. UVB leads to sunburn while UVA leads to pigmentation (tanning). Because frequent sunburn was often associated with skin cancer, UVB was assumed, naively, to be the culprit, he says.

Exposure to sunlight induces a sense of well-being, increases the libido, reduces appetite and induces the synthesis of large amounts of vitamin D, an essential nutritional factor. The use of sunscreen creams reduces vitamin D levels and low levels of vitamin D have been associated with breast and colon cancer. Prof. Sinclair says the 17% increase in breast cancer from 1981 to 1991 parallels the vigorous use of sunscreens over the same period.

Among the risk factors for the development of tumours are a family history, tendency to freckle, more than three episodes of severe sunburn during childhood, and the use of artificial UV light tanning booths. He says it remains a question whether to tan or not. It was earlier believed that the main carcinogenic rays were UVB and that UVA merely induced a tan. The increase in UVA exposure could have severe consequences.

Prof. Sinclair says the UV light used in artificial tanning booths consists mainly of pure UVA which are highly dangerous rays. It has been estimated that six per cent of all melanoma deaths in the UK can be directly attributed to the use of artificial tanning lights. The use of an artificial tanning booth will double the melanoma risk of a person. “UVA is solely responsible for solar skin aging and it is ironical that tanning addicts, who want to look beautiful, are inflicting accelerated ageing in the process,” he says.

On the use of sunscreens he says it can prevent painful sunburn, but UVA-induced damage continues unnoticed. UVB blockers decrease vitamin D synthesis, which is a particular problem in the elderly. It also prevents the sunburn warning and therefore increases the UVA dosage that an individual receives. It creates a false sense of security which is the biggest problem associated with sunscreens.

Evidence obtained from the state of Queensland in Australia, where the heaviest and longest use of sunscreens occurred, boasted the highest incidence of melanoma in the world. A huge study in Norway has shown a 350% increase in melanoma for men and 440% for women. This paralleled the increase in the use of UVB blocking sunscreens while there was no change in the ozone layer. It did however, occur during that time when tanning became fashionable in Norway and there was an increase especially in artificial tanning.

Prof. Sinclair says: “We believe that sunscreen use does not directly lead to melanoma, but UVA exposure does. The Melanoma Epidemic is a reality. Sunscreen preparations are not the magical answer in the fight against melanoma and the irresponsible use of these preparations can worsen the problem.”
