Home-based HIV counselling and testing in western Kenya.

BACKGROUND: The World Health Organisation (WHO) estimates that only 12% of men and 10% of women in sub-Saharan Africa have been tested for HIV and know their test results. Home-based counselling and testing (HBCT) offers a novel approach to complement facility-based provider initiated testing and counselling (PITC) and voluntary counselling and testing (VCT) and could greatly increase HIV prevention opportunities. However, there is almost no evidence that large-scale, door-to-door testing is even feasible in settings with both limited resources and significant stigma around HIV and AIDS. OBJECTIVE: To describe our experience with the feasibility and acceptance of home-based HIV counselling and testing (HBCT) in two large, rural, administrative divisions of western Kenya. DESIGN: The USAID-AMPATH Partnership conducted population-based, house-to-house HIV counselling and testing in western Kenya between June 2007 and June 2009. All individuals aged > or = 13 years and all eligible children were offered HBCT. Children were eligible if they were above 13 years of age, and their mother was either HIV-positive or had unknown HIV serostatus, or if their mother was deceased or whose vital status was unknown. SETTING: Kosirai and Turbo Divisions, Rift Valley Province, Kenya. RESULTS: There were 47,066 households approached in 294 villages: 97% of households allowed entry. Of the 138,026 individuals captured, 101,167 individuals were eligible for testing: 89% of adults and 58% of children consented to HIV testing. The prevalence of HIVin these communities was 3.0%: 2.7% in adults and 3.7% among children. Prevalence was highest in the 36-45 year age group and was almost always higher among women and girls. All persons testing HIV-positive were referred to Academic Model Providing Access to Healthcare (AMPATH) for further assessment and care; all consenting persons were counselled on HIV risk-lowering behaviours. CONCLUSION: Home-based HIV counselling and testing was feasible among this rural population in western Kenya, with a majority of the population accepting to get tested. These data suggest that scaling-up of HBCT is possible and may enable large numbers of individuals to know their HIV serostatus in sub-Saharan Africa. More research is needed to describe the cost-effectiveness and clinical impact of this approach.

Task shifting in HIV clinics, Western Kenya.

BACKGROUND: United states Agency for International development-Academic Model for Providing Accesses to Healthcare (USAID-AMPATH) cares for over 80,000 HIV-infected patients. Express care (EC) model addresses challenges of: clinically stable patient's adherent to combined-antiretroviral-therapy with minimal need for clinician intervention and high risk patients newly initiated on cART with CD4 counts < or = 100 cells/mm3 with frequent need for clinician intervention. OBJECTIVE: To improve patient outcomes without increasing clinic resources. DESIGN: A descriptive study of a clinician supervised shared nurse model. SETTING: USAID-AMPATH clinics, Western Kenya. RESULTS: Four thousand eight hundred and twenty four patients were seen during the pilot period, 90.4% were eligible for EC of whom 34.6% were enrolled. Nurses performed all traditional roles and attended to two thirds and three quarters of stable and high risk patient visits respectively. Clinicians attended to one third and one quarter of stable and high risk patient visits respectively and all visits ineligible for express care. CONCLUSION: The EC model is feasible. Task shifting allowed stable patients to receive visits with nurses, while clinicians had more time to concentrate on patients that were new as well as more acutely ill patients.

Risk factors for death in HIV-infected adult African patients receiving anti-retroviral therapy.

OBJECTIVE: To determine risk factors for death in HIV-infected African patients on anti-retroviral therapy (ART). DESIGN: Retrospective Case-control study. SETTING: The MOH-USAID-AMPATH Partnership ambulatory HIV-care clinics in western Kenya. RESULTS: Between November 2001 and December 2005 demographic, clinical and laboratory data from 527 deceased and 1054 living patients receiving ART were compared to determine independent risk factors for death. Median age at ART initiation was 38 versus 36 years for the deceased and living patients respectively (p<0.0148). Median time from enrollment at AMPATH to initiation of ART was two weeks for both groups while median time on ART was eight weeks for the deceased and fourty two weeks for the living (p<0.0001). Patients with CD4 cell counts <100/mm3 were more likely to die than those with counts >100/mm3 (HR=1.553. 95% CI (1.156, 2.087), p<0.003). Patients attending rural clinics had threefold higher risk of dying compared to patients attending clinic at a tertiary referral hospital (p<0.0001). Two years after initiating treatment fifty percent of non-adherent patients were alive compared to 75% of adherent patients. Male gender, WHO Stage and haemoglobin level <10 grams% were associated with time to death while age, marital status, educational level, employment status and weight were not. CONCLUSION: Profoundly immunosuppressed patients were more likely to die early in the course of treatment. Also, patients receiving care in rural clinics were at greater risk of dying than those receiving care in the tertiary referral hospital.

Determinants in HIV counselling and testing in couples in North Rift Kenya.

BACKGROUND: Voluntary HIV counselling and testing (VCT) has been shown to be an acceptable and effective tool in the fight against HIV/AIDS. Couple HIV Counselling and Testing (CHCT) however, is a relatively new concept whose acceptance and efficacy is yet to be determined. OBJECTIVE: To describe factors that motivate couples to attend VCT as a couple. DESIGN: A cross sectional qualitative study. SETTING: Moi Teaching and Referral Hospital and Moi University, School of Medicine, Eldoret, Kenya SUBJECTS: Seventy one individuals were interviewed during KII (9) and dyad interviews (31 couples). Ten FGDs involving a total of 109 individuals were held. RESULTS: Cultural practices, lack of CHCT awareness, stigma and fear of results deter CHCT utilisation. Location of centre where it is unlikely to be associated with HIV testing, qualified professional staff and minimal waiting times would enhance CHCT utilisation. CONCLUSIONS: CHCT as a tool in the fight against HIV/AIDS in this region of Kenya is feasible as the factors that would deter couples are not insurmountable.

Stakeholders perception of HIV sero-discordant couples in western Kenya.

OBJECTIVE: To describe the perceptions of key stakeholders regarding the counselling needs of HIV sero-discordant couples as part of preparation for a clinical trial involving HIV sero-discordant couples. DESIGN: Qualitative study using key informant and couple interviews. SETTING: Moi Teaching and Referral Hospital (MTRH). SUBJECTS: A purposive sample of nine key informants and 31 couple interviews totaling 71 participants. The couple interviews consisted of HIV untested, HIV concordant (positive and negative) and discordant couples. RESULTS: Seventy one individuals participated in nine key informant and 31 couple interviews. The responses identified the following as key issues in counselling HIV discordant couples: The need for education on the meaning of HIV sero-discordancy including potential sources of infection; assistance in disclosing HIV test results to one's partner; discussion of the stigma surrounding formula feeding. Overall, the participants supported safer sexual practices in discordant partnerships. CONCLUSIONS: Psychosocial support of HIV sero-discordant couples should include messages about the meaning, mechanisms and implications of sero-discordancy. Culturally appropriate HIV-disclosure and safer sex messages are also needed to support these partnerships.

The Mosoriot medical record system: design and initial implementation of an outpatient electronic record system in rural Kenya.

Mosoriot Health Center is a rural primary care facility situated on the outskirts of Eldoret, Kenya in sub-Saharan Africa. The region is characterised by widespread poverty and a very poor technology infrastructure. Many houses do not have electricity, telephones or tap water. The health center does have electricity and tap water. In a collaborative project between Indiana University and the Moi University Faculty of Health Sciences (MUFHS), we designed a core electronic medical record system within the Mosoriot Health Center, with the intention of improving the quality of health data collection and, subsequently, patient care. The electronic medical record system will also be used to link clinical data from the health center to information collected from the public health surveys performed by medical students participating in the public health research programs of Moi University. This paper describes the processes involved in the development of the computer-based Mosoriot medical record system (MMRS) up to the point of implementation. It particularly focuses on the decisions and trade-offs that must be made when introducing this technology into an established health care system in a developing country.

Perinatal morbidity at the Moi Teaching and Referral Hospital, Eldoret.

BACKGROUND: Perinatal morbidity (PNM) is highest in the developing countries including Kenya. Studies on the perinatal morbidity in Moi Teaching and Referral Hospital (MTRH) have not been carried out. Furthermore, factors associated with PNM are unknown at the MTRH. OBJECTIVE: To establish the causes and incidence of perinatal morbidity at the MTRH NewBorn Unit (NBU). DESIGN: A retrospective study using case notes. SETTING: The NBU of the MTRH in Eldoret, Kenya. SUBJECTS: Babies who were admitted to the MTRH's Newborn Unit from January to December 1997. RESULTS: The perinatal morbidity was 667 per 1000 babies admitted to the NBU. The most common reason for admission was mother under anaesthesia. The most common cause of morbidity was asphyxia. The mean maternal age was 24 years. The mean level of education was 1.7 years. More than fifty five per cent of the mothers were housewives. The mean birthweight was 2.75 kg (+/- 0.9 SD), 55.9% had normal birthweight, 37% were low birthweight and three per cent were large babies. The mean duration of stay in the NBU was 3.8 days. CONCLUSION: Most of the admissions were Caesarean section babies who did not require admission. Younger mothers were more likely to have babies with neonatal sepsis, convulsions, pneumonia and asphyxia.

'Triangulating' AMPATH: demonstration of a multi-perspective strategic programme evaluation method.

Clinical programmes are typically evaluated on operational performance metrics of cost, quality and outcomes. Measures of patient satisfaction are used to assess the experience of receiving care, but other perspectives, including those of staff and communities, are not often sought or used to assess and improve programmes. For strategic planning, the Kenyan HIV/AIDS programme AMPATH (Academic Model Providing Access to Healthcare) sought to evaluate its performance in 2006. The method used for this evaluation was termed 'triangulation', because it used information from three different sources--patients, communities, and programme staff. From January to August 2006, Indiana University external evaluators and AMPATH staff gathered information on strengths, weaknesses and suggestions for improvement of AMPATH. Activities included in-depth key-informant semi-structured interviews of 26 AMPATH clinical and support staff, 56 patients at eight clinic sites, and seven village health dialogues (mabaraza) at five sublocations within the AMPATH catchment area. Data sources included field notes and transcripts of translated audio recordings, which were subjected to qualitative content analysis. Eighteen recommendations for programme improvement emerged, including ten from all three respondent perspectives. Three recommendations were cited by patients and in mabaraza, but not by staff. Triangulation uncovered improvement emphases that an internal assessment would miss. AMPATH and Kenyan Ministry of Health leadership have deliberated these recommendations and accelerated strategic change actions, including rural satellite programmes, collaboration with village-based workers, and door-to-door village-based screening and counselling.

Equitable treatment for HIV/AIDS clinical trial participants: a focus group study of patients, clinician researchers, and administrators in Western Kenya.

OBJECTIVES: To describe the concerns and priorities of key stakeholders in a developing country regarding ethical obligations held by researchers and perceptions of equity or "what is fair" for study participants in an HIV/AIDS clinical drug trial. DESIGN: Qualitative study with focus groups. SETTING: Teaching and referral hospital and rural health centre in Western Kenya. PARTICIPANTS: Potential HIV/AIDS clinical trial participants, clinician researchers, and administrators. RESULTS: Eighty nine individuals participated in a total of 11 focus groups over a four month period. The desire for continued drug therapy, most often life long, following an HIV/AIDS clinical trial was the most common priority expressed in all focus groups. Patients with and without HIV/AIDS also thought subsidizing of drug therapies and education were critical forms of compensation for clinical trial participation. Financial incentives were considered important primarily for purchasing drug therapy as well as obtaining food. Patients noted a concern for the potential mismanagement of any money offered. Clinician researchers and administrators felt strongly that researchers have a moral obligation to participants following a trial to provide continued drug therapy, adverse event monitoring, and primary care. Finally, clinician researchers and administrators stressed the need for thorough informed consent to avoid coercion of study participants. CONCLUSIONS: Kenyan patients, clinician researchers, and administrators believe that it would be unfair to stop antiretroviral therapy following an HIV/AIDS clinical trial and that researchers have a long term obligation to participants.
