Using fourth-year medical students’ reflections to propose strategies for primary care physicians, who host students in their practices, to optimise learning opportunities
M Van Rooyen
South African Family Practice , 2012,
Abstract: Setting and subjects: Fourth-year medical students at the University of Pretoria are required to work with a primary healthcare practitioner for two weeks. After the preceptorship, reflective photo-story reports on the students’ experiences and personal and academic growth are submitted. Objectives: To identify whether the objectives of the preceptorship were met and to describe the experiences of students, the reflective reports were qualitatively analysed. A second purpose of the analysis was to propose strategies that could be implemented by the primary healthcare practitioners to optimise the learning experience of students in their practices. Design: A qualitative approach to analyse the narratives of the photo-story reports was used. Main and subthemes were identified from the topics that were thought about. Quotes from the narratives were selected to support the themes. Each of the quotes was then scrutinised to ascertain if evidence of learning had taken place. Results: The main themes were identified as: the impact that the visit had had on the student, the emotions that they had experienced, working with the physician, interacting with patients and the clinical care of patients. Learning was achieved under conditions that made the students feel comfortable, confident, happy and inspired; required their active participation; challenged them; inspired them to see the advantage of learning; and when feedback was given to them. Conclusion: Strategies for use by practitioners to optimise the learning experience of students in their practices were proposed. These included active student participation, reflection, the creation of a positive environment, student participation in challenging experiences, active learning and quality time spent with patients.
The views of medical students on professionalism in South Africa
M Van Rooyen
South African Family Practice , 2004,
Abstract: An article on medical professionalism was published in the Annals of Internal Medicine in February 2002 outlining a charter, and the fifth-year medical students of the Medical School of the University of Pretoria were asked to comment on the charter. The question was asked whether the principles and responsibilities as set out in the charter could also be applied to the South African context. The responses of the students could be divided into three groups with overlapping themes: 15,64% of the students felt that the charter was not at all applicable to our country because of its diverse cultures and languages and the variety of social classes and religions; 24,02% of the students felt that the charter was a universally acceptable document; and 60,34% of the students felt that, to a great extent, the charter was the ideal and the goal to strive for, although they only accepted some of the principles and responsibilities while having serious doubts and criticism of others. In conclusion, the majority of the medical students felt that the charter was noteworthy and commendable in principle, but not totally applicable in our country with its unique problems and challenges. Our challenge is to take what resources we have and use it to the benefit of all.
Pretoria medical students' perspectives on assessable attributes of Professionalism
M van Rooyen, I Treadwell
South African Family Practice , 2007,
Abstract: Background Professionalism forms an important aspect of medicine's contract with society, and it is therefore important that it should be assessed and developed in medical schools. For the effective assessment of medical students' professionalism, clear objectives, or outcomes based on a clear definition of professionalism, have to be accepted by society, the faculty and the students. A Physician's Charter, ‘Medical Professionalism in the New Millennium , was published by the Annals of Internal Medicine in February 2002. Fifth-year medical students of the University of Pretoria were challenged to comment on the applicability of this Charter's principles and responsibilities in the South African context. The majority of the students did not fully agree with the principles and responsibilities. A following cohort of fifth-year students was requested to define professionalism and describe attributes that could be included in an assessment tool. Methods A qualitative design was employed to explore the students' perceptions. An analysis of the scripts was performed using qualitative content analysis. All the scripts were read twice and the emergent themes (attributes of professionalism) were identified by two researchers. The scripts were reviewed and coded independently to enhance reliability. Investigator triangulation, involving researchers with diverse research backgrounds, was done to validate the identified attributes. The themes were organised into categories (domains of professionalism). The authors discussed differing concepts with the other members of the Professional Attitude Development and Assessment Committee (PADAC) to arrive at a consensus. In the second stage of analysis, the identified themes were compared to the Charter. This was supported by quotations taken from the students' perceptions, as well as from the relevant literature. Tabulations were used to determine the frequencies of the different themes. Results The attributes used to describe professionalism were grouped under four main domains: attitude and personal conduct, teamwork, patient care and professional competence. These correspond, to some extent, with the Charter. Most of the students, however, stressed the humanistic attributes of professional behaviour, which are not mentioned in the Charter. These attributes include empathy, interpersonal relationships, integrity, respect, maturity and teamwork. Conclusion The students' perceptions of professionalism differed from that described in the Charter. The fact that the students value the humanistic part of professionalism could possibly be ascribed to the following factors: Teaching of professionalism at the University of Pretoria focuses on the humanistic attributes, which form an important part of patient consultations and teamwork. Medical students are not actively involved in the social contract that is prominent in the Charter. They have very little influence regarding social justice, access to care, distributio
The prevalence of post-abortion syndrome in patients presenting at Kalafong Hospital's Family Medicine Clinic after having a termination of pregnancy
M Van Rooyen, S Smith
South African Family Practice , 2004,
Abstract: Background: Post-abortion syndrome (PAS) is said to be the emotional, psychological, physical and spiritual trauma caused by an abortion, which is an event outside the normal range of human experience. Post-abortion syndrome is a type of post-traumatic disorder and is characterised by a stressor (the abortion), the event being re-experienced, avoidance and/or numbing of general responsiveness, and physical symptoms such as insomnia and depression. The question was asked whether the patients at Kalafong Hospital experienced any of the after-effects of a termination of pregnancy and whether these effects would fulfill the criteria of post-abortion syndrome. Method: A prospective descriptive study was done over a six-month period. All female patients presenting at the Family Medicine Clinic of Kalafong Hospital who were known to have had a previous abortion on request were asked to participate in the study. After obtaining informed consent, a structured questionnaire on their psychological symptoms was completed by the participants with the help of the researcher. The questionnaire contained demographic data, as well as questions on the above-mentioned symptoms of PAS. To fulfill the criteria of PAS, the symptoms should have been present for more than a month and must have affected the subject's daily functioning. Results: Of the 48 woman recruited, 16 (33%) fulfilled the criteria of PAS, and more than 50% of the women had had some or other emotional or psychological after-effect. Conclusion: This study showed that one out of every three women presenting at Kalafong Hospital after abortion fulfilled the criteria of PAS. Since family physicians are committed to their patients and regard it as their duty to address problems prevalent in the community they serve, it is necessary to investigate further the possible link between termination of pregnancy and the emotional problems identified. It is imperative that women requesting termination of pregnancy receive comprehensive counseling prior to the procedure, as well as support thereafter, to ensure that they are not unnecessarily traumatised.

Technique to study the impact of large herbivores on woody vegetation within piospheres
J. Brits,M.W. van Rooyen,N. van Rooyen
Koedoe : African Protected Area Conservation and Science , 2000, DOI: 10.4102/koedoe.v43i2.198
Abstract: A continuously sampled transect away from a watering point provides good results in situations where geology and soil type remain constant, but is unsuitable to apply where regular changes in soil type occur. A comparison was made between a continuously sampled transect and sampling taken at intervals along the transect. An analysis of variance indicated no significant differences in any of the variables obtained by means of the two sampling methods. The advantage of interval sampling is that, within each zone, areas with the same soil type can be selected in order to avoid environmental heterogeneity. A comparison between transects made in different directions from the watering point yielded no significant differences in any of the structural variables of the woody vegetation at the same distance from the watering point. Therefore, combining transects from different directions to attain a representative sample away from the watering point was an acceptable practice. It is recommended that the original data be smoothed and the logistic function used to model the impact of large herbivores on the structure of the woody vegetation around watering points.

Margaretha W. van Rooyen,Noel van Rooyen,Jacobus du P. Bothma,Hendrik M. van den Berg
Koedoe : African Protected Area Conservation and Science , 2008, DOI: 10.4102/koedoe.v50i1.154
Abstract: A landscape map of the Kalahari Gemsbok National Park is presented. Mapping is at a finer scale than previous vegetation and habitat maps for the same area. The landscapes were grouped into seven large classes and a total of 20 landscapes were mapped. A description of the terrain morphology, soil and vegetation of each landscape is provided. Landscapes that are focal points for the large animals of the region include the calcrete outcrops, riverbeds and pans. These landscapes cover only about 10% of the total area of the region. This map can be used as basis for park planning, management, research and other applications.
Impact of harvesting and fire on Phragmites australis reed quality in Tembe Elephant Park, Maputaland
M.W. van Rooyen,C.A. Tosh,N. van Rooyen,W.S. Matthews
Koedoe : African Protected Area Conservation and Science , 2004, DOI: 10.4102/koedoe.v47i1.76
Abstract: In Maputaland, South Africa, the common reed (Phragmites australis) is used extensively for hut building, fencing, craftwork and thatching. As a result of over-harvesting most reed beds in communal areas have been degraded and are no longer producing reeds of the desired quality. At present the most productive reed beds are all found in conservation areas. The KwaMsomi area of the Muzi Swamp in the Tembe Elephant Park has been allocated to the Sibonisweni community for harvesting purposes. This community has recently requested Ezemvelo KwaZulu-Natal Wildlife for additional areas for harvesting on the grounds that the current site was no longer yielding reeds of suitable quality. The main objective of this study was therefore to determine whether there was a decline in reed quality in the KwaMsomi harvested area. The results of this study suggest that harvested areas contained more thin, short reeds than unharvested areas. Fire can be used to increase reed diameter in harvested areas, but will not significantly affect reed height. Ideally, reeds should only be harvested after the active growth period, when most of the nutrient reserves have been translocated to the rhizomes and the buds are still dormant. To improve reed quality a three-year rotational harvesting programme should be implemented to allow the reeds to recover fully before being harvested again.
The infl uence of banks’ internal performance on market performance: a non-parametric approach
M Oberholzer, G van der Westhuizen, S van Rooyen
Southern African Business Review , 2010,
Abstract: The purpose of the study is to determine the degree to which banks’ market performance, as measured by market value ratios, is aff ected by their internal performance. Annual fi nancial statement reports were used to determine the internal and market performance of listed banks on the JSE Limited over a ten-year period. The internal performance measures used are the profi tability ratios in the Du Pont analysis and two Data Envelopment Analysis (DEA) models to estimate effi ciency. Income statement data were included as the output of the fi rst model to determine banks’ operating effi ciency, and balance sheet data were included as the output of the second model to determine banks’ fi nance and investment effi ciency. The study concluded that market value ratios correlate better with profi tability ratios than the income statement output-based and balance sheet output-based effi ciencies. This study is the fi rst to compare two DEA models and profi tability ratios with market value ratios. The value of the study is therefore that it indicates that profi tability ratios should be used as a proxy for market value ratios rather than effi ciency measures that focus separately on income statement data and balance sheet data.
Caring for terminal AIDS patients: The experiences of caregivers in palliative care institution
M Williams, R Magdalena van Rooyen, E Ricks
Health SA Gesondheid , 2009,
Abstract: This research focused on the lived experiences of caregivers working with Acquired Immune Defi ciency Syndrome patients, particularly patients who die from this disease whilst resident in a formal institution. A qualitative, exploratory, descriptive, and contextual research design with a phenomenological approach to inquiry was utilised. 13 unstructured interviews, which were audio-taped, were conducted with caregivers working full-time in a formal institution caring for patients who are dying from AIDS. The transcribed interviews were analysed using Tesch’s method of descriptive analysis (in Creswell 1994:115). One central theme emerged, namely that in their daily duty (at their place of work), caregivers experienced various challenges as a result of having to deal with the death of their patients suffering from AIDS, and fi ve sub-themes were formulated from further analysis. The fi ve sub-themes were: Caregivers experienced emotional challenges in caring for patients dying of AIDS Caregivers experienced a difference in death and dying of adults as opposed to children Caregivers experienced the rationalisation of death and dying differently Caregivers experienced that faith in God gives them strength to cope with death and dying Caregivers experienced caring for patients as fulfi lling and meaningful to them despite the sadness of death and dying. The participants face the death of their patients daily, from a disease that causes untold suffering to the patients, family members and to the caregivers themselves, who wish they could prevent the anguish, the pain and the inability of the medical profession to do more than they are at present towards curing this disease. They described their emotional experiences, which included the various challenges that they face as a result of having to deal with the death and dying of their patients suffering from AIDS. The information shared by these participants formed the foundation of the broad guidelines that were developed in order to provide support for such caregivers. OPSOMMING Die fokus van hierdie navorsing was op die beleefde ervaringe van die versorgers wat met Verworwe Immuniteitsgebreksindroom pasi nte werk, veral pasi nte wat sterf aan die siekte terwyl hulle in 'n formele inrigting is. 'n Kwalitatiewe, eksploratiewe, beskrywende en kontekstuele navorsingsontwerp met 'n fenomenologiese benadering was gebruik. 13 ongestruktue rde onderhoude, wat op 'n audioband opgeneem was is gehou met versorgers wat voltyds in 'n formele inrigting sorg vir pasi nte wat aan VIGS sterf werk. Tesch se metode van beskrywende analise was gebruik om die transkribeerde onderhoude te analiseer (in Cresswell 1994:115). Een sentrale tema het na vore gekom, naamlik dat versorgers tydens die uitvoering van hulle daaglikse pligte (in die werk) 'n verskeidenheid uitdagings ondervind het as gevolg van hul pasi nte wat sterf van VIGS en vyf sub-temas is geformuleer deur verdure analise. Hierdie vyf sub-temas was:
Drinking during marathon running in extreme heat: a video analysis study of the top finishers in the 2004 Athens Olympic marathons
M van Rooyen, T Hew-Butler, TD Noakes
South African Journal of Sports Medicine , 2010,
Abstract: Objective. To assess the drinking behaviours of top competitors during an Olympic marathon. Methods. Retrospective video analysis of the top four finishers in both the male and female 2004 Athens Olympic marathons plus the pre-race favourite in the female race in order to assess total time spent drinking. One male and female runner involved in a laboratory drinking simulation trial. Results. For the five female athletes, 37 of a possible 73 drinking episodes were captured. The female race winner was filmed at 11 of 15 drinking stations. Her total drinking time was 23.6 seconds; extrapolated over 15 seconds this would have increased to 32.2 seconds for a total of 27 sips of fluid during the race. Eighteen of a possible 60 drinking episodes for the top four male marathon finishers were filmed. The total drinking time for those 18 episodes was 11.4 seconds. A laboratory simulation found that a female athlete of approximately the same weight as the female Olympic winner might have been able to ingest a maximum of 810 ml (350 ml.h-1) from 27 sips whilst running at her best marathon pace whereas a male might have drunk a maximum of 720 ml (330 ml.h-1) from 9 sips under the same conditions. Conclusions. These data suggest that both the female and male 2004 Olympic Marathon winners drank minimal total amounts of fluid (<1 litre) in hot (>30oC) temperatures while completing the marathon with race times within 2.5% of the Olympic record.
