Changing clinical needs of people living with AIDS and receiving home based care in Malawi--the Bangwe Home Based Care Project 2003-2008--a descriptive study.

BACKGROUND: Home based care (HBC) has been an important component of the response to the AIDS epidemic in Africa, and particularly so before antiretroviral therapy (ART) became available. Has HBC become unnecessary now that ART is available in many African countries? One way to investigate this is to assess the changing need for comprehensive HBC as an ART programme becomes available. The Bangwe HBC programme in Malawi has been collecting data since 2003 before ART became available in 2005/6. Has the introduction of ART changed the clinical needs for HBC? METHODS: Information obtained at initial assessment and follow up visits of patients receiving HBC were combined to assess case severity, survival and the response to treatment. This information was used to assess trends in mortality and the incidence, duration and severity of common symptoms over a six year period in a defined urban population in Malawi. RESULTS: 1266 patients, of whom 1190 were followed up and of whom 652 (55%) died, were studied. 282 (25%) patients died within two months of being first seen with an improvement between 2003-2005 and 2006-2008 of reduced mortality from 28% to 20%. 341 (27%) patients were unable to care for themselves on first assessment and 675 (53%) had stage 4 AIDS disease. Most patients had a mix of symptoms at presentation. Self care increased somewhat over the six years although case severity as measured by WHO staging and nutritional status did not.350 patients were on ART either started before or after initial assessment. There were significant barriers to accessing ART with 156 (51%) of 304 stage 3 or 4 patients first assessed in 2007 or 2008 not receiving ART.Over the six year period new HBC cases reduced by 8% and follow up visits increased by 9% a year. Between 4 and 5 people sought HBC for the first time each week from an urban health centre catchment of 100,000, which required 37.3 follow up visits each week. CONCLUSIONS: Since the availability of ART in the local health facilities and despite strenuous efforts to persuade people to seek HIV testing and ART, in practice barriers existed and half the eligible HBC patients did not have access to ART. This is one reason why the clinical need for HBC services had not changed much. In terms of quantity of care the number of new patients seeking HBC reduced by 8% a year. In terms of content of care, while there had been a marginal increase in self care the severity of illness had not changed and the survival of a significant proportion of patients generated the need for repeat visits, which increased by 9% a year. In conclusion, although the content has changed the need for HBC has not diminished despite the availability of ART.

The pattern of symptoms in patients receiving home based care in Bangwe, Malawi : a descriptive study.

BACKGROUND: Home based care of HIV/AIDS patients is a health need recommended but not often available in Africa. Population based assessment helps to identify unmet health needs to plan services. Careful assessment and follow up of patients receiving home based care in a defined population of Bangwe, Malawi provides details of the frequency and severity of common symptoms. METHODS: Mortality and the incidence, duration and severity of common symptoms of patients in a defined population receiving home based care were measured over an eighteen month period. RESULTS: 358 patients, of whom 199 died, were studied. A third of patients died within 4 months of being first seen. About half the patients were unable to care for themselves on first assessment. Half were malnourished with a Body Mass Index (BMI) < 18.5 kg/m2. Most patients had a mixture of symptoms at presentation. These symptoms responded to treatment usually within a fortnight. However a small proportion (5%) of patients suffered repeated episodes often as many as 6-9 times a year. Incidence rates are estimated. CONCLUSION: Symptoms which are alleviated by simple treatments are common. The patients in whom symptoms recur need a responsive home based care service. Population based estimates of incidence and duration of disease and the visit work load allow an assessment of home based care needs in an urban setting in Africa.

An assessment of food supplementation to chronically sick patients receiving home based care in Bangwe, Malawi: a descriptive study.

BACKGROUND: The effect of food supplementation provided by the World Food Programme to patients and their families enrolled in a predominantly HIV/AIDS home based care programme in Bangwe Malawi is assessed. METHODS: The survival and nutritional status of patients and the nutritional status of their families recruited up to six months before a food supplementation programme started are compared to subsequent patients and their families over a further 12 months. RESULTS: 360 patients, of whom 199 died, were studied. Food supplementation did not improve survival but had an effect (not statistically significant) on nutritional status. Additional oil was given to some families; it may have improved survival but not nutritional status. CONCLUSION: Food supplementation to HIV/AIDS home based care patients and their families does not work well. This may be because the intervention is too late to affect the course of disease or insufficiently targeted perhaps due to problems of distribution in an urban setting. The World Food Programme's emphasis on supplementary feeding for these families needs to be reviewed.
