- ItemDescribing final diagnosis and outcome for patients investigated for suspected acute coronary syndrome at a regional, public South African emergency centre(Stellenbosch : Stellenbosch University, 2018-12) Kabongo, Diulu; Allgaier, Rachel; Bruijns, S.; Kalla, M.ENGLISH SUMMARY : No abstract available.
- ItemDescribing suspected non ST-elevation acute coronary syndrome using troponin at a regional, public South African emergency centre with the Roche cardiac reader(South African Heart Association, 2018) Kabongo, Diulu; Kalla, Moosa; Allgaier, Rachel; Bruijns, StevanBackground: There are few data available regarding acute coronary syndrome presenting to emergency centres in sub-Saharan Africa compared to the rest of the world. The aim of this study was to describe the acute coronary syndrome diagnosis and its outcome in an undifferentiated chest pain population when using a troponin assay that predates current reference standards at a public, Cape Town emergency centre. Methods: A retrospective, cross-sectional design was used. Comparisons were made between the diagnosis, outcome and troponin result (using the Roche cardiac reader). Findings were descriptively presented. Troponin results were qualitatively described in relation to a non ST-elevation acute coronary syndrome diagnosis. Associations were tested using the Chi2-test. Results: Nine hundred and sixty-nine patients were included in the study, of which 40 patients (4%) were excluded due to poor clinical record keeping. Acute coronary syndrome was diagnosed in 256 patients (28%), from which 54 (21%) were troponin positive which differed to troponin negative acute coronary syndrome (p <0.001). Unstable angina was diagnosed in 197 (77%) of acute coronary syndrome patients. Conclusions: Unsurprisingly, a high proportion of chest pain patients did not have acute coronary syndrome. Unstable angina numbers were much higher than described elsewhere. Although it is not possible to relate this finding to the assay’s lower accuracy using only a descriptive design, a higher sensitivity assay would likely benefit the diagnostic process as it does elsewhere. Further research is required to explore safe, local diagnostic strategies that can strike a balance between patient safety and cost effectiveness.
- ItemEffectiveness of home-based directly obeserved treatment for tuberculosis in Kweneng West subdistrict, Botswana(AOSIS Publishing, 2010) Kabongo, Diulu; Mash, BobBackground: Tuberculosis (TB) and HIV are major public health problems in Botswana. In the face of growing TB notification rates, a low cure rate, human resource constraints and poor accessibility to health facilities, Botswana Ministry of Health decided to offer home-based directly observed treatment (DOT) using community volunteers. Objectives: The aim of this study was to assess the outcomes of home-based directly observed treatment (HB-DOT) versus facility-based, directly observed treatment (FB-DOT) in the Kweneng West subdistrict in Botswana and to explore the acceptability of HB-DOT among TB patients, community volunteers and health workers. Method: A quantitative, observational study using routinely collected TB data from 405 TB patients was conducted and combined with 20 qualitative in-depth interviews. Results: The overall cure rate for smear-positive pulmonary TB patients was 78.5%. Treatment outcomes were not statistically different between FB-DOT and HB-DOT. Contact tracing was significantly better in FB-DOT patients. Interviews revealed advantages and disadvantages for both FB and HB options and that flexibility in the choice or mix of options was important. A number of suggestions were made by the interviewees to improve the HB-DOT programme. Conclusion: HB-DOT is at least as good as FB-DOT in terms of the treatment outcomes, but attention must be given to contact tracing. HB-DOT offers some patients the flexibility they need to adhere to TB treatment and community volunteers may be strengthened by ongoing training and support from health workers, financial incentives and provision of basic equipment.
- ItemEffectiveness of home-based directly observed treatment for tuberculosis in Kweneng West subdistrict, Botswana.(Stellenbosch : Stellenbosch University, 2009-12) Kabongo, Diulu; Mash, Bob; University of Stellenbosch. Faculty of Health Sciences. Dept. of Interdisciplinary Health Sciences. Family Medicine and Primary Care.ENGLISH: ABSTRACT: Introduction: Tuberculosis and HIV are major public health problems in Botswana. The Botswana National Tuberculosis Control Programme (BNTP) was established in 1975. Short course chemotherapy was introduced in 1986 and the Directly Observed Treatment (DOT) Strategy was adopted in 1993. In the face of growing TB notification rates, a low country average cure rate, human resource constraints in health facilities and sometimes poor accessibility to health facilities by weak patients and those living far away, Botswana decided to offer home-based care using volunteers or family members. Setting: Kweneng West Subdistrict, a rural area in Botswana Aim and objectives: The aim of this study was to assess the success of home-based DOT in the management of tuberculosis compared to facility-based DOT in Kweneng West Subdistrict, Botswana and to explore the acceptability of home-based DOT among TB patients, TB treatment supervisors and health workers. Objectives: - To compare treatment outcomes for patients receiving home-based DOT and those receiving facility-based DOT through the following criteria: - To compare patient contact(s) tracing efforts among home-based providers and facility-based providers - To establish TB patient’s, TB treatment supervisor’s and health worker’s perceptions about home-based DOT Methods: A quantitative, observational study combined with qualitative in-depth interviews. Participants were selected from TB patients who attended treatment from January 2006 till June 2008 at all main clinics of Kweneng West Subdistrict, Botswana. The interview purposively selected health care workers, TB patients and community supervisors to establish their thoughts about HB DOT. A framework approach was used to analyse interviews. Results: Treatment outcomes and, particularly, the cure rates were not statistically different between FB DOT, HB DOT and MX DOT. However there was a surprisingly difference in contact tracing, with FB DOT performing better than other DOT types. Interviews revealed that patients were happy with their choice of DOT types. Among reasons to choose HB DOT was the need to shorten distances for DOT. Among reasons to choose FB DOT were the needs to ensure safety through supervision by nurses as opposed to lay people (community supervisors) and to obtain injections that no community supervisor is allowed to administer. A mix of HB DOT and FB DOT was generally adopted to allow flexibility in the administration of DOT for few patients. Overall cure rate was 78.5% and successful treatment rate was 83%. Conclusion: The introduction of HB DOT and the option given to choose this DOT type is supported. Indeed allowing patient’s preference of DOT type may impact positively on patients’ satisfaction and adherence to medication. On the other hand, issues were still raised by all stakeholders to help improve the flexibility and sustainability of HB DOT. Further studies may be needed to understand the better performance of FB DOT in contact tracing.
