RESUMO
OBJECTIVE: Before proceeding with local implementation of competency-based medical education-related assessment practices designed and evaluated in the Global North, we sought to challenge the assumption that this would be perceived as both necessary and acceptable in our context where training and assessment is based on a traditional, knowledge-focused approach. The aim of this study was to determine the perspectives of general surgery trainees and consultants towards the assessment of competence, how this has been achieved previously, and how it should be performed in the future at the University of Cape Town (UCT), South Africa. DESIGN: Semi-structured interviews were conducted with consultants and trainees. Interviews were transcribed and then analyzed using a Reflexive Thematic Analysis approach. SETTING AND PARTICIPANTS: Ten consultants (5 senior and 5 junior) and 10 trainees (5 South African and 5 international) from the Division of General Surgery at UCT in August 2022. RESULTS: Five unique themes were developed: (1) Assessment of competence is essential, (2) competence includes multiple domains of practice, (3) a surgeon must be able to operate, (4) previously used methods were inadequate to assess competence, and (5) frequent assessment with feedback is desired. The themes were considered in the context of Situated Learning Theory, particularly Communities of Practice and their role in the training for, and authentic assessment of, competence in general surgery trainees. CONCLUSIONS: Participants described a need to develop and implement a new competency assessment program for general surgery training in this context, which is aligned with described competency-based medical education principles. Thoughtful integration of the formative and summative use of direct observation in the workplace, with a clear emphasis on procedural ability and the provision of high-quality feedback, may enhance the successful implementation of a strategy for competency-based assessment in general surgery training programs.

Motion capture is the current gold standard for assessing movement of the human body, but laboratory settings do not always mimic the natural terrains and movements encountered by humans. To overcome such limitations, a smart sock that is equipped with stretch sensors is being developed to record movement data outside of the laboratory. For the smart sock stretch sensors to provide valuable feedback, the sensors should have durability of both materials and signal. To test the durability of the stretch sensors, the sensors were exposed to high-cycle fatigue testing with simultaneous capture of the capacitance. Following randomization, either the fatigued sensor or an unfatigued sensor was placed in the plantarflexion position on the smart sock, and participants were asked to complete the following static movements: dorsiflexion, inversion, eversion, and plantarflexion. Participants were then asked to complete gait trials. The sensor was then exchanged for either an unfatigued or fatigued plantarflexion sensor, depending upon which sensor the trials began with, and each trial was repeated by the participant using the opposite sensor. Results of the tests show that for both the static and dynamic movements, the capacitive output of the fatigued sensor was consistently higher than that of the unfatigued sensor suggesting that an upwards drift of the capacitance was occurring in the fatigued sensors. More research is needed to determine whether stretch sensors should be pre-stretched prior to data collection, and to also determine whether the drift stabilizes once the cyclic softening of the materials comprising the sensor has stabilized.

Trip-induced falls are extremely common in ergonomic settings. Such situations can lead to fatal or non-fatal injuries, affecting the workers' quality of life and earning capacity. Dual tasking (DT) is a leading cause of trips and ineffective obstacle clearance among workers. DT increases their attentional demand, challenging both postural control and concurrent secondary tasks. As the human brain has limited attentional processing capacity, even young, healthy adults need to prioritize duties during DT. This article aimed to analyze these secondary task types and their applications in recent trip-related studies conducted on young, healthy adults. An extensive review of the recent trip-related literature was performed to provide a condensed summary of the dual tasks used. In previous trip-related literature, distinct types of secondary tasks were used. The choice of the concurrent task must be made vigilantly depending on the occupation, environmental context, available resources, and feasibility. DT can be used as a tool to train workers on selective attention, which is a lifesaving skill in ergonomic settings, especially in the occupations of roofers, construction workers, or truck drivers. Such training can result in successful obstacle clearance and trip recovery skills, which eventually minimizes the number of falls at the workplace.

BACKGROUND: Postural strategies such as ankle, hip, or combined ankle-hip strategies are used to maintain optimal postural stability, which can be influenced by the footwear type and physiological workload. PURPOSE: This paper reports previously unreported postural strategy scores during the six conditions of the sensory organization test (SOT). METHODS: Fourteen healthy males (age: 23.6 ± 1.2 years; height: 181 ± 5.3 cm; mass: 89.2 ± 14.6 kg) were tested for postural strategy adopted during SOT in three types of occupational footwear (steel-toed work boot, tactical work boot, low-top work shoe) every 30 min during a 4-h simulated occupational workload. Postural strategy scores were analyzed using repeated measures analysis of variance at 0.05 alpha level. RESULTS: Significant differences among postural strategy scores were only evident between SOT conditions, and but not between footwear type or the workload. CONCLUSIONS: Findings indicate that occupational footwear and occupational workload did not cause a significant change in reliance on postural strategies. The significant changes in postural strategy scores were due to the availability of accurate and/or conflicting sensory feedback during SOT conditions. In SOT conditions where all three types of sensory feedback was available, the ankle strategy was predominantly adopted, while more reliance on hip strategy occurred in conditions with absent or conflicting sensory feedback.

There is scarce research into the use of Strive Sense3 smart compression shorts to measure external load with accelerometry and muscle load (i.e., muscle activations) with surface electromyography in basketball. Sixteen external load and muscle load variables were measured from 15 National Collegiate Athletic Association Division I men's basketball players with 1137 session records. The data were analyzed for player positions of Centers (n = 4), Forwards (n = 4), and Guards (n = 7). Nonparametric bootstrapping was used to find significant differences between training and game sessions. Significant differences were found in all variables except Number of Jumps and all muscle load variables for Guards, and all variables except Muscle Load for Forwards. For Centers, the Average Speed, Average Max Speed, and Total Hamstring, Glute, Left, and Right Muscle variables were significantly different (p < 0.05). Principal component analysis was conducted on the external load variables. Most of the variance was explained within two principal components (70.4% in the worst case). Variable loadings of principal components for each position were similar during training but differed during games, especially for the Forward position. Measuring muscle activation provides additional information in which the demands of each playing position can be differentiated during training and competition.

Standards for the fatigue testing of wearable sensing technologies are lacking. The majority of published fatigue tests for wearable sensors are performed on proof-of-concept stretch sensors fabricated from a variety of materials. Due to their flexibility and stretchability, polymers are often used in the fabrication of wearable sensors. Other materials, including textiles, carbon nanotubes, graphene, and conductive metals or inks, may be used in conjunction with polymers to fabricate wearable sensors. Depending on the combination of the materials used, the fatigue behaviors of wearable sensors can vary. Additionally, fatigue testing methodologies for the sensors also vary, with most tests focusing only on the low-cycle fatigue (LCF) regime, and few sensors are cycled until failure or runout are achieved. Fatigue life predictions of wearable sensors are also lacking. These issues make direct comparisons of wearable sensors difficult. To facilitate direct comparisons of wearable sensors and to move proof-of-concept sensors from "bench to bedside", fatigue testing standards should be established. Further, both high-cycle fatigue (HCF) and failure data are needed to determine the appropriateness in the use, modification, development, and validation of fatigue life prediction models and to further the understanding of how cracks initiate and propagate in wearable sensing technologies.
RESUMO
The purpose of this study was to evaluate the use of compressible soft robotic sensors (C-SRS) in determining plantar pressure to infer vertical and shear forces in wearable technology: A ground reaction pressure sock (GRPS). To assess pressure relationships between C-SRS, pressure cells on a BodiTrakTM Vector Plate, and KistlerTM Force Plates, thirteen volunteers performed three repetitions of three different movements: squats, shifting center-of-pressure right to left foot, and shifting toes to heels with C-SRS in both anterior-posterior (A/P) and medial-lateral (M/L) sensor orientations. Pearson correlation coefficient of C-SRS to BodiTrakTM Vector Plate resulted in an average R-value greater than 0.70 in 618/780 (79%) of sensor to cell comparisons. An average R-value greater than 0.90 was seen in C-SRS comparison to KistlerTM Force Plates during shifting right to left. An autoregressive integrated moving average (ARIMA) was conducted to identify and estimate future C-SRS data. No significant differences were seen in sensor orientation. Sensors in the A/P orientation reported a mean R2 value of 0.952 and 0.945 in the M/L sensor orientation, reducing the effectiveness to infer shear forces. Given the high R values, the use of C-SRSs to infer normal pressures appears to make the development of the GRPS feasible.
RESUMO
BACKGROUND: World-wide, rural clinical training of undergraduate medical students is looking to transform learning experiences, calling for the adoption of innovative approaches that create spaces for curriculum renewal and new ways of thinking. In order for these teaching models to gain acceptance and credibility among the relevant academic communities, it is critical that they be studied and evaluated. AIM: This article describes an innovative rural education intervention and a concomitant, intentional process that was adopted to establish a research framework within which the intervention will be evaluated. METHODS: Key role-players participated in a one-day workshop aimed at developing the framework. A collaborative, structured process that moved through three phases of deliberation and reflection was followed. RESULTS: The documentation and raw data generated during the workshop was used to generate the framework that will serve as a blueprint for ensuring the study and evaluation of the educational innovation. CONCLUSION: Establishing an educational research framework, by adopting a consultative and collaborative process, provides a vehicle for encouraging a culture of critical accountability that seeks to discern evidence of good practice in the training of health care workers in a rural context.

BACKGROUND: Medical education faces challenges posed by widening access to training, a demand for globally competent healthcare workers and progress towards harmonisation of standards. AIM: To explore potential challenges arising from variation in diversity and educational background of medical school entrants. METHOD: This study investigated the reported experience and confidence, in a range of 31 generic skills underpinning learning, of 2606 medical undergraduates entering 14 medical schools in England and South Africa, using a validated questionnaire. RESULTS: Responses suggest that there is considerable similarity in prior educational experience and confidence skills profiles on entry to South African and English medical schools. South African entrants reported significantly more experience in 'Technical skills', 'Managing their own Learning', and 'Presentation', while English students reported increased experience in 'IT' skills. South African undergraduates reported more confidence in 'Information Handling', while English students were more confident in 'IT' skills. The most noticeable difference, in 'IT' skills, is probably due to documented differences in access to computer facilities at high school level. Differences between individual schools within each country are noticeable. CONCLUSIONS: Educators need to acquire a good understanding of their incoming cohorts, and ensure necessary tailored support for skills development.

OBJECTIVES: Hospitalisation for medical illness has ongoing impact on individuals, healthcare services and society beyond discharge. This study's objective was to determine the 12-month mortality and functional outcomes of patients admitted to the acute medical service at Groote Schuur Hospital (GSH). METHODS: Follow-up, using the hospital records system and provincial death registry, together with telephonic interviews or home visits, was attempted for 465 medical inpatients admitted to GSH between 14 September and 16 November 2009. Functional outcomes were assessed using the Katz activities of daily living (ADL) score and Barthel index (BI). Outcome measures. The major study outcomes included: 12-month mortality (overall and unexpected), changes in functional status and pre- and post-admission employment rates. RESULTS: Inpatient mortality was 11%. At 12-month follow-up, 35% (145/415) were deceased and 30% (125/415) could not be traced; 38% (55/145) of deaths were considered expected and unexpected mortality was associated with age >40 years (p=0.02) and an admission urea >7.0 mmol/l (p=0.004). Katz ADL deteriorated in 15% (21/143) of interviewed patients and was associated with age >50 years (p=0.005); 23% (33/143) had improved Katz ADL associated with admission human immunodeficiency virus (HIV) (p=0.01), tuberculosis (TB) infection (p=0.05) and sepsis (p=0.02). Employment rates declined from 41% (59/145) pre-admission to 18% (26/145) at 12 months (p<0.001), with little increase in the number of persons receiving disability grants. Twenty per cent (29/145) of patients required hospital readmission and this was associated with ADL functional decline (p=0.01). CONCLUSIONS: There was a very high overall mortality of 42% in patients admitted to the general medical wards. Significant employment decline and readmission rates highlight the additional economic and societal burdens of hospitalisation due to medical illness in the survivors.

INTRODUCTION: Sub-Saharan Africa(SSA) is the world region worst affected by physician migration. Identifying reasons why medical students wish to stay or leave Africa could assist in developing strategies which favour retention of these graduates. This study investigated the career intentions of graduating students attending medical schools in SSA to identify interventions which may improve retention of African physicians in their country of training or origin. METHODS: Final year medical students attending nine medical schools in SSA were surveyed--students from four schools in South Africa and one school each in the Democratic Republic of Congo, Kenya, Nigeria, Tanzania and Uganda. The response rate was 78.5% (990 of 1260 students); data from the 984 students who indicated they were remaining in medicine were entered into a database, and descriptive statistics were obtained. RESULTS: Most (97.4%) of the 984 responding students were African by birth. The majority (91.2%) intended to undertake postgraduate training; the top three specialty choices were surgery (20%), internal medicine (16.7%), and paediatrics (9%). Few were interested in family medicine (4.5%) or public health (2.6%) or intended to practice in rural areas (4.8%). Many students (40%) planned to train abroad. About one fifth (21%) intended to relocate outside sub-Saharan Africa. These were about equally divided between South Africans (48%) and those from the other five countries (52%). The top perceived career-related factors favouring retention in Africa were career options and quality and availability of training opportunities. Several factors were reported significantly more by South African than the other students. The top personal factors for staying in Africa were a desire to improve medicine in Africa, personal safety, social conditions and family issues. The top career-related factors favouring relocation outside Africa were remuneration, access to equipment and advanced technology, career and training opportunities, regulated work environment and politics of health care in Africa. Several of these were reported significantly more by students from the other countries as compared with South Africans. The top personal factors favouring relocation outside Africa were personal safety, opportunity for experience in a different environment, social conditions and greater personal freedom. DISCUSSION: The career intentions of African medical students are not aligned with the continent's health workforce needs. A number of interventions that warrant further attention were identified in this study.

INTRODUCTION: Public health care delivery in South Africa aims to provide equitable access at the most appropriate level of care. We studied to what extent the acute health care needs of adults admitted to public hospitals in the Cape Town Metropole were being appropriately met. METHODS: A retrospective study was conducted of the hospital records of adults admitted to medical beds in public hospitals in Cape Town between August and November 2008. Intensive care unit patients were not included. RESULTS: Of 802 beds in use, the estimated occupancy was at least 95%. The average time elapsed since admission was 7.9 days; 94.3% of medical admissions were acute; 45% were severely to critically ill on admission; and co-morbid disease was present in 78.1%. Of all admissions, 31.9% were HIV-positive, and 17% had active tuberculosis. At least 396 (51.6%) patients were deemed to have required specialist or subspecialist consultation to expedite appropriate care; 386 (50.3%) accessed the appropriate level of medical care required; 339 (44.2%) accessed a more sophisticated level of care than required; and 42 (5.5%) did not access an adequate level of care. CT scan and ultrasound accounted for 59% of all restricted tests done. CONCLUSIONS: Our findings support the plan to provide more primary care hospital facilities in the metropolitan area. Most patients needing specialised care are accessing such care, and most patients accessing a higher level of care than needed can be addressed by ensuring that they first access primary care and are referred according to protocols.

This study aims to ascertain the perception of cervical screening practices among HIV-positive women attending an ART clinic in urban South Africa. It is a prospective cross-sectional study of 100 randomly selected patients using semi-structured interviews. Answers to fixed-response questions were recorded for statistical analysis and themes were identified from responses to open-ended questions. The study found that 59% of women surveyed reported ever having had a Papanicolau (Pap) smear and that 41% of these women had never been notified of the result. Many women surveyed lacked understanding of cervical screening; 78% had never heard of cervical cancer and around 40% had no correct knowledge about Pap smears. The findings suggest that cervical screening practices among HIV-positive women living in urban South Africa do not comply with the recommendations that are based on evidence of increased risk for this population. Systematic cervical screening programmes should be offered to HIV-positive women attending ART clinics in South Africa.

BACKGROUND: The modified early warning score (MEWS) is a useful tool for identifying hospitalised patients in need of a higher level of care and those at risk of inhospital death. Use of the MEWS as a triage tool to identify patients needing hospital admission and those at increased risk of inhospital death has been evaluated only to a limited extent. AIM: To evaluate the use of the MEWS as a triage tool to identify medical patients presenting to the emergency department who require admission to hospital and are at increased risk of inhospital death. METHODS: Physiological parameters were collected from 790 medical patients presenting to the emergency department of a public hospital in Cape Town, South Africa. MEW scores were calculated from the data and multivariate regression analysis was performed to identify independent predictors of hospital admission and inhospital mortality. RESULTS: The proportion of patients admitted and those who died in hospital increased significantly as the MEW score increased (p<0.001). Multivariate regression analysis identified five independent predictors of hospital admission: systolic blood pressure < or =100 mm Hg, pulse rate > or =130 beats per minute, respiratory rate > or =30 breaths per minute, temperature > or =38.5 degrees C and an impaired level of consciousness. Independent predictors of inhospital death were: abnormal systolic blood pressure (< or =100 or > or =200 mm Hg), respiratory rate > or =30 breaths per minute and an impaired level of consciousness. CONCLUSION: The MEWS, specifically five selected parameters, may be used as a rapid, simple triage method to identify medical patients in need of hospital admission and those at increased risk of inhospital death.

BACKGROUND: Until recently South Africa had no triage system for emergency department (ED) use. The Cape triage group developed a triage scale called the Cape triage score (CTS). This system consists of a basic physiology score, mobility score and a short list of important discriminators that cannot be accurately triaged on a physiological score alone. Highest priority is given to a red colour code, followed by orange, yellow and green. AIM: The purpose was to evaluate the components of the CTS and identify amendments that would improve the quality of the scale in terms of its accuracy to identify patients more likely to require admission or at high risk of death in the ED. METHODS: Data were prospectively collected over a 4-month period. Data captured included the parameters of a basic physiological score (respiratory rate, pulse rate, systolic blood pressure, temperature and a simplified score measuring level of consciousness), mobility, a list of selected clinical conditions (discriminator list), final clinical diagnosis and final outcome in the ED (admission to hospital or death). RESULTS: 798 patients were triaged and analyzed. The CTS undertriaged 24% (overtriage 25%) of cases who required admission. By altering the colour code parameters, amending the discriminator list as well as the addition of a trauma factor, undertriage was reduced to 12% (with an overtriage of 45%). CONCLUSIONS: The amended CTS has an acceptably low undertriage rate and is capable of predicting patient disposal over a wide spectrum of ED presentations.

BACKGROUND: In a resource poor setting with poverty, a high burden of disease and critically low medical staff numbers, triage could potentially improve the long waiting times experienced at South African public hospital emergency departments (ED) and render timely emergency care to those in most need. AIM: To evaluate the impact of introducing nurse triage (using the Cape Triage Score (CTS)) on waiting times for patients presenting to a South African public hospital ED. METHODS: Pre-triage waiting times were collected retrospectively through accessing hospital records of four randomly chosen months of the preceding year. This was compared with data collected prospectively over a 3 month period using nurse triage and the CTS triage tool. Captured data included CTS priority category, time of nurse triage and time of attendance by ED doctor. RESULTS: Waiting times were significantly reduced in all but the lowest priority category. The introduction of nurse triage, using the CTS, resulted in an overall reduction in waiting time from 237 min to 146 min (p<0.001). Patients triaged "red" (highest priority) demonstrated a mean reduction in waiting time from 216 min to 38 min (p<0.001). CONCLUSIONS: The results demonstrate that use of the CTS, as implemented by trained nurses, dramatically reduced the waiting time of patients attending a busy public hospital ED in South Africa.

High stakes postgraduate specialist certification examinations have considerable implications for the future careers of examinees. Medical colleges and professional boards have a social and professional responsibility to ensure their fitness for purpose. To date there is a paucity of published data about the reliability of specialist certification examinations and objective methods for improvement. Such data are needed to improve current assessment practices and sustain the international credibility of specialist certification processes. To determine the component and composite reliability of the Fellowship examination of the College of Physicians of South Africa, and identify strategies for further improvement, generalizability and multivariate generalizability theory were used to estimate the reliability of examination subcomponents and the overall reliability of the composite examination. Decision studies were used to identify strategies for improving the composition of the examination. Reliability coefficients of the component subtests ranged from 0.58 to 0.64. The composite reliability of the examination was 0.72. This could be increased to 0.8 by weighting all test components equally or increasing the number of patient encounters in the clinical component of the examination. Correlations between examination components were high, suggesting that similar parameters of competence were being assessed. This composite certification examination, if equally weighted, achieved an overall reliability sufficient for high stakes examination purposes. Increasing the weighting of the clinical component decreased the reliability. This could be rectified by increasing the number of patient encounters in the examination. Practical ways of achieving this are suggested.

BACKGROUND AND OBJECTIVES: Diabetes affects approximately 1 million South Africans. Hospital admissions, the largest single item of diabetes expenditure, are often precipitated by hyperglycaemic emergencies. A recent survey of a 200- bed hospital, serving approximately 1.3 million Cape Town residents, showed that hyperglycaemic emergencies comprised 25.6% of high-care unit admissions. A study was undertaken to determine the reasons for, and financial cost of, these admissions. METHODS: All hyperglycaemic admissions during a 2-month period (1 September - 31 October 2005) were surveyed prospectively. Admissions were classified using the American Diabetes Association classification of hyperglycaemic emergencies. Demographic data, and the reason for, duration of and primary outcome of admission, were recorded. The following costs per admission were calculated using publicsector pricing: (i) total costs; (ii) patient-specific costs; (iii) nonpatient- specific costs; and (iv) capital costs. RESULTS: Sepsis (36%), non-compliance with therapy (32%) and a new diagnosis of diabetes (11%) were the predominant reasons for admission of 53 hyperglycaemic emergency cases. Mean duration of hospital stay was 4 days, with an in-hospital mortality of 7.5%. Mean cost per admission was R5 309. Clinical staff (25.8%), capital (25.6%) and overhead (34%) costs comprised 85.4% of expenditure. DISCUSSION AND RECOMMENDATIONS: Hyperglycaemic admissions, costing more than R5 300 per patient, represent a health burden that has remained unchanged over the past 20 years. Urgently required primary care preventive strategies include early diagnosis of diabetes, timely identification and treatment of precipitating causes, specifically sepsis, and education to improve compliance.

CONTEXT: The maldistribution of physicians in sub-Saharan Africa is having serious impacts on population health. Understanding the effect requires investigation from both donor and recipient countries. However, investigation from the perspective of donor countries has been lacking. METHODS: This brief communication describes a model process for the design of a research project that addresses medical migration issues from the perspective of eight African medical schools. During an international meeting, the participants designed an initial "ideal" study, and then rapidly tested its feasibility through a brief survey, and group discussion through a listserv, teleconferences and one face-to-face meeting. FINDINGS AND PRACTICAL IMPLICATIONS: Innovative research ideas can be followed-up with surveys to test the feasibility of an "ideal" research design, modifying the design accordingly. This is currently occurring with our medical migration survey study.
