A Retrospective analysis of Spondyloarthropathies at the Rheumatic Diseases Unit, University of Cape Town, over the period 1988-1994
OBJECTIVES: Given the paucity of epidemiological and clinical data representing the South African experience with the spondyloarthropathies, a study was designed to achieve a description of the spectrum of spondyloarthropathy in patients of different ethnic origin attending the Rheumatic Diseases Unit (RDU), University of Cape Town (UCT), in respect of differences in: clinical and/or radiographic expression of disease; gender HLA-B27 status, and choice of therapy and requirements for reconstructive orthopaedic surgical procedures. STUDY DESIGN: The study comprised a retrospective descriptive review of all new cases of spondyloarthropathy seen at the RDU, UCT Medical School, from 1 January 1988 to 31 December 1994, who were consecutively identified from an analysis of the clinical records. The RDU (UCT) is one of two principal referral centres for rheumatic-related diseases in the Western Cape region, and provides clinical services at Groote Schuur Hospital (GSH, Observatory) and Princess Alice Orthopaedic Hospital (PAOH, Retreat) in Cape Town for an estimated population of 3. 4 million (Western Cape), 55% (1.9 million) of whom are resident in the Cape Peninsula region (81). A minority of patients from further afield (Northern Cape and Eastern Cape) also attend the unit. Approximately 12 500 patients attend PAOH outpatient Department (OPD) annually, of which 35% are seen by the RDU staff each year (average values calculated from attendance registers for the period 1 January 1988 to 31 December 1994). New patients constitute about 6% of all patients seen by the RDU per annum (Table 2). Statistical data were not available from the OPD Arthritis Clinic (AC) at GSH, but similar proportions would be expected, since both clinics are staffed by the same complement of doctors and operate under similar circumstances at both venues
A comparison of physician emigration from Africa to the United States of America between 2005 and 2015
BACKGROUND: Migration of health professionals has been a cause for global concern, in particular migration from African countries with a high disease burden and already fragile health systems. An estimated one fifth of African-born physicians are working in high-income countries. Lack of good data makes it difficult to determine what constitutes "African" physicians, as most studies do not distinguish between their country of citizenship and country of training. Thus, the real extent of migration from African countries to the United States (US) remains unclear. This paper quantifies where African migrant physicians come from, where they were educated, and how these trends have changed over time. METHODS: We combined data from the Educational Commission for Foreign Medical Graduates with the 2005 and 2015 American Medical Association Physician Masterfiles. Using a repeated cross-sectional study design, we reviewed the available data, including medical school attended, country of medical school, and citizenship when entering medical school. RESULTS: The outflow of African-educated physicians to the US has increased over the past 10 years, from 10 684 in 2005 to 13 584 in 2015 (27.1% increase). This represents 5.9% of all international medical graduates in the US workforce in 2015. The number of African-educated physicians who graduated from medical schools in sub-Saharan countries was 2014 in 2005 and 8150 in 2015 (304.6% increase). We found four distinct categorizations of African-trained physicians migrating to the US: (1) citizens from an African country who attended medical school in their own country (86.2%, n = 11,697); (2) citizens from an African country who attended medical school in another African country (2.3%, n = 317); (3) US citizens who attended medical school in an African country (4.0%, n = 537); (4) citizens from a country outside Africa, and other than the United States, who attended medical school in an African country (7.5%, n = 1013). Overall, six schools in Africa provided half of all African-educated physicians. CONCLUSIONS: The number of African-educated physicians in the US has increased over the past 10 years. We have distinguished four migration patterns, based on citizenship and country of medical school. The majority of African graduates come to the US from relatively few countries, and from a limited number of medical schools. A proportion are not citizens of the country where they attended medical school, highlighting the internationalization of medical education
Towards a Conceptual Framework for Interdisciplinary Teaching and Learning Dialogues in Higher Education
This paper explores the development and early validation of a conceptual framework for learning-centred teaching by six Teaching Advancement at Universities (TAU) Fellows and their mentor, each representing a different higher education institution and a different discipline. A grounded theory approach was used to construct the framework and its potential utility value was explored though the use of six teaching innovation projects conducted in undergraduate South African university programmes in law, medicine, education, and the arts. The project revealed that interdisciplinary dialogic spaces can be initiated and nurtured through opportunities offered by communities of practice such as the TAU Fellowship when academics suspend their exclusive disciplinary preoccupations to open up possibilities for a generative, emancipatory scholarship. We argue that the conceptual framework is useful to facilitate and promote dialogues across and between the multiple discipline specific ontologies, epistemologies and methodologies offered in higher education
The need for appropriate critical care service provision at non-tertiary hospitals in South Africa
The impact of a faculty development programme for health professions educators in sub-Saharan Africa: an archival study
BACKGROUND:
In 2008 the sub-Saharan FAIMER Regional Institute launched a faculty development
programme aimed at enhancing the academic and research capacity of health professions
educators working in sub-Saharan Africa. This two-year programme, a combination of
residential and distance learning activities, focuses on developing the leadership, project
management and programme evaluation skills of participants as well as teaching the key
principles of health professions education-curriculum design, teaching and learning and
assessment. Participants also gain first-hand research experience by designing and conducting
an education innovation project in their home institutions. This study was conducted to
determine the perceptions of participants regarding the personal and professional impact of
the SAFRI programme.
METHODS:
A retrospective document review, which included data about fellows who completed the
programme between 2008 and 2011, was performed. Data included fellows’ descriptions of
their expectations, reflections on achievements and information shared on an online
discussion forum. Data were analysed using Kirkpatrick’s evaluation framework.
RESULTS:
Participants (n=61) came from 10 African countries and included a wide range of health
professions educators. Five key themes about the impact of the SAFRI programme were
identified: (1) belonging to a community of practice, (2) personal development, (3)
professional development, (4) capacity development, and (5) tools/strategies for project
management and/or advancement.
CONCLUSION:
The SAFRI programme has a positive developmental impact on both participants and their
respective institutions.National Research FoundationDepartment of HE and Training approved lis
Clinically contextualised ECG interpretation: the impact of prior clinical exposure and case vignettes on ECG diagnostic accuracy
Background
ECGs are often taught without clinical context. However, in the clinical setting, ECGs are rarely interpreted without knowing the clinical presentation. We aimed to determine whether ECG diagnostic accuracy was influenced by knowledge of the clinical context and/or prior clinical exposure to the ECG diagnosis.
Methods
Fourth- (junior) and sixth-year (senior) medical students, as well as medical residents were invited to complete two multiple-choice question (MCQ) tests and a survey. Test 1 comprised 25 ECGs without case vignettes. Test 2, completed immediately thereafter, comprised the same 25 ECGs and MCQs, but with case vignettes for each ECG. Subsequently, participants indicated in the survey when last, during prior clinical clerkships, they have seen each of the 25 conditions tested. Eligible participants completed both tests and survey. We estimated that a minimum sample size of 165 participants would provide 80% power to detect a mean difference of 7% in test scores, considering a type 1 error of 5%.
Results
This study comprised 176 participants (67 [38.1%] junior students, 55 [31.3%] senior students, 54 [30.7%] residents). Prior ECG exposure depended on their level of training, i.e., junior students were exposed to 52% of the conditions tested, senior students 63.4% and residents 96.9%. Overall, there was a marginal improvement in ECG diagnostic accuracy when the clinical context was known (Cohen’s d = 0.35, p < 0.001). Gains in diagnostic accuracy were more pronounced amongst residents (Cohen’s d = 0.59, p < 0.001), than senior (Cohen’s d = 0.38, p < 0.001) or junior students (Cohen’s d = 0.29, p < 0.001). All participants were more likely to make a correct ECG diagnosis if they reported having seen the condition during prior clinical training, whether they were provided with a case vignette (odds ratio [OR] 1.46, 95% confidence interval [CI] 1.24–1.71) or not (OR 1.58, 95% CI 1.35–1.84).
Conclusion
ECG interpretation using clinical vignettes devoid of real patient experiences does not appear to have as great an impact on ECG diagnostic accuracy as prior clinical exposure. However, exposure to ECGs during clinical training is largely opportunistic and haphazard. ECG training should therefore not rely on experiential learning alone, but instead be supplemented by other formal methods of instruction
Mortality in patients treated for tuberculous pericarditis in sub-Saharan Africa.
Tuberculous pericarditis is one of the most severe forms of extrapulmonary tuberculosis, causing death or disability in a substantial proportion of affected people.1,2 In Africa, the incidence of tuberculous pericarditis is rising as a result of the HIV epidemic.3 The effect of HIV infection on survival in patients with tuberculous pericarditis is unknown.2,4 Whereas some investigators have suggested that HIV-infected patients with tuberculous pericarditis have a similar outcome to non-infected cases,5 others have shown that there may be an increase in mortality in HIV associated with tuberculous pericarditis.2,6,7 We established a prospective observational study, the Investigation of the Management of Pericarditis in Africa (IMPI Africa) registry, to obtain current information on the diagnosis, management and outcome of patients with presumed tuberculous pericarditis living in sub-Saharan Africa, where the burden of HIV infection is the greatest in the world.4,8-10 In this paper, we report the mortality rate and its predictors during the 6 months of antituberculosis treatment among patients enrolled in the regis
Clinical characteristics and initial management of patients with tuberculous pericarditis in the HIV era: the Investigation of the Management of Pericarditis in Africa (IMPI Africa) registry
BACKGROUND: The incidence of tuberculous pericarditis has increased in Africa as a result of the human immunodeficiency virus (HIV) epidemic. However, the effect of HIV co-infection on clinical features and prognosis in tuberculous pericarditis is not well characterised. We have used baseline data of the Investigation of the Management of Pericarditis in Africa (IMPI Africa) registry to assess the impact of HIV co-infection on clinical presentation, diagnostic evaluation, and treatment of patients with suspected tuberculous pericarditis in sub-Saharan Africa. METHODS: Consecutive adult patients in 15 hospitals in three countries in sub-Saharan Africa were recruited on commencement of treatment for tuberculous pericarditis, following informed consent. We recorded demographic, clinical, diagnostic and therapeutic information at baseline, and have used the chi-square test and analysis of variance to assess probabilities of significant differences (in these variables) between groups defined by HIV status. RESULTS: A total of 185 patients were enrolled from 01 March 2004 to 31 October 2004, 147 (79.5%) of whom had effusive, 28 (15.1%) effusive-constrictive, and 10 (5.4%) constrictive or acute dry pericarditis. Seventy-four (40%) had clinical features of HIV infection. Patients with clinical HIV disease were more likely to present with dyspnoea (odds ratio [OR] 3.2, 95% confidence interval [CI] 1.4 to 7.4, P = 0.005) and electrocardiographic features of myopericarditis (OR 2.8, 95% CI 1.1 to 6.9, P = 0.03). In addition to electrocardiographic features of myopericarditis, a positive HIV serological status was associated with greater cardiomegaly (OR 3.89, 95% CI 1.34 to 11.32, P = 0.01) and haemodynamic instability (OR 9.68, 95% CI 2.09 to 44.80, P = 0.0008). However, stage of pericardial disease at diagnosis and use of diagnostic tests were not related to clinical HIV status. Similar results were obtained for serological HIV status. Most patients were treated on clinical grounds, with microbiological evidence of tuberculosis obtained in only 13 (7.0%) patients. Adjunctive corticosteroids were used in 109 (58.9%) patients, with patients having clinical HIV disease less likely to be put on them (OR 0.37, 95% CI 0.20 to 0.68). Seven patients were on antiretroviral drugs. CONCLUSION: Patients with suspected tuberculous pericarditis and HIV infection in Africa have greater evidence of myopericarditis, dyspnoea, and haemodynamic instability. These findings, if confirmed in other studies, may suggest more intensive management of the cardiac disease is warranted in patients with HIV-associated pericardial disease
