Development and validation of a tool to measure patient experience in chronic disease care.

BACKGROUND:  There is a global increase in the prevalence of non-communicable diseases and a growing understanding that patients need to be involved in their care. Patient experience should be assessed and the information used to improve on the planning and delivery of health services. AIM:  This study described the development and validation of a patient-reported experience measure (PREM) tool which is appropriate for the South African context, to assess self-reported patient experience of chronic care. SETTING:  The study was conducted at four primary health care facilities in the Cape Town Metropole. METHODS:  This was a validity and reliability study with multiple phases to develop and determine the psychometric properties of a novel tool. It consisted of three phases, namely: Phase 1 - Consensus Validity; Phase 2 - Face Validity; Phase 3 - Reliability. Phase 1 consisted of an expert panel reaching consensus on a draft tool. Phase 2a consisted of qualitative semi-structured interviews and cognitive interviews. Phase 3 tested the internal consistency of the tool, the time necessary to complete, as well as floor and ceiling effects with 200 questionnaires. RESULTS:  The process described resulted in a final questionnaire with n = 10 items in three languages that was easily understood by patients. Internal consistency was determined with the overall Cronbach's alpha 0.86. This PREM has been named Chronic Care Assessment of Patient Experience. CONCLUSION:  Using best practice guidance in tool construction and validation, we delivered a PREM with the potential to improve the quality of care from the perspective of patients. Implementation studies are now required to determine how best to use this tool in routine practice.

Profile and anticoagulation outcomes of patients on warfarin therapy in an urban hospital in Cape Town, South Africa.

BACKGROUND: Warfarin is the most frequently used oral anticoagulant worldwide and it is the oral anticoagulant of choice in South Africa for reducing thrombosis-related morbidity and mortality. However, the safety and efficacy of warfarin therapy depends mainly on careful monitoring and maintenance of the international normalised ratio (INR) within an optimal therapeutic range. AIM: The aim of this study was to describe the profile and the anticoagulation outcomes of patients on warfarin therapy in a major warfarin clinic in the Western Cape Province of South Africa. SETTING: Victoria Hospital - a district hospital in Cape Town. METHODS: A cross sectional review of clinical records of patients on warfarin therapy who attended the INR clinic from 01 January 2014 to 30 June 2014 was done. Data analysis was done with STATA to generate appropriate descriptive data. RESULTS: Our study showed that atrial fibrillation (AF) was the commonest indication for warfarin use in this study and hypertension was the commonest comorbidity among these patients. Only 48.5% achieved target therapeutic range; 51.5% were out-of-range. There was a significant association between alcohol consumption and poor anticoagulation outcomes (p-value < 0.022). Anticoagulation outcomes were better among the older age groups, male patients and in those with AF. The prevalence of thrombotic events while on warfarin treatment was 2.2%, while prevalence of haemorrhagic events was 14%. Most of the patients with bleeding events were on concurrent use of warfarin and other medications with potential drug interactions. CONCLUSION: In our study, patients who achieved target therapeutic control were less than the acceptable 60%.

Family medicine in South Africa: where are we now and where do we want to be?

OBJECTIVES: This paper outlines the development of family medicine in South Africa with special reference to the process leading to the recognition of this discipline as a medical specialty. It also examines the constraints under which the discipline has had to function, considers where the discipline should be, seeks to identify the barriers to its further development and suggests ways in which to overcome these. METHODS: A short review was carried out of the available South African literature to record the advancement of the discipline and the international literature was searched for articles supporting this direction. RESULTS: The situation in South Africa is complicated by the existence of many doctor groupings claiming to represent the generalist and the perception that family medicine only addresses the needs of middle-class citizens. A flawed consultative process leading up to the present stage has contributed to this perception. CONCLUSIONS: The available literature supports the establishment of family medicine as a speciality. Developments in South Africa, such as raising the status of Family Medicine and creating a compulsory rotation through family medicine as an extended internship and the creation of registrar posts in family medicine will advance the discipline in a positive manner, whilst possibly attempting to resolve the medical migration issues that are presently destroying Sub-Saharan Africa's health services.

Diabetes mellitus and non-traumatic lower extremity amputations in four public sector hospitals in Cape Town, South Africa, during 2009 and 2010.

BACKGROUND: Diabetes mellitus (DM) is the most commonly reported cause of non-trauma-related lower extremity amputations (LEAs) worldwide, but there is a dearth of such information for South Africa (SA). OBJECTIVES: To examine the proportion of LEAs due to diabetes and to describe the associated characteristics of these patients. METHODS: A retrospective analysis of all LEAs was performed in four public sector hospitals in Cape Town, SA, for 2009 and 2010. Operating theatre records were reviewed to identify all patients who had an LEA. Patient records were perused and information extracted using a structured questionnaire. RESULTS: Records for 941 of 1,134 patients identified as having an LEA were found (recovery rate 82.9%). Of the 867 patients with 1,280 LEAs included in the study, 925 LEAs were in 593 patients with DM and 355 LEAs in 274 non-DM patients. Therefore 72.3% (95% confidence interval (CI) 69.8-74.7) of LEAs were in people with DM, while 68.4% (95% CI 65.2-71.4) of the total patients had DM. The DM group underwent more multiple LEAs (42.0% v. 23%; p<0.001) and had more multiple admissions (14.3% v. 7.7%; p<0.005) than the non-DM group. Infection (85.7% v. 63.5%,; p<0.001) and ulcer (25.3% v. 15.3%; p=0.001) were the leading causes for LEA in the DM group compared with the non-DM group. Ischaemia was the dominant cause in the non-DM patients (49.3% v. 23.3%; p<0.001), as was smoking (69.7% v. 43.5%, p<0.001), compared with the DM patients. CONCLUSIONS: These data demonstrate an alarming burden of LEAs due to DM in the public sector in Cape Town. Given that the majority of LEAs are preventable with adequate education, screening, treatment and follow-up, effective interventions are needed.
