A study of patient attitudes towards decentralisation of HIV care in an urban clinic in South Africa

<p>Abstract</p> <p>Background</p> <p>In South Africa, limited human resources are a major constraint to achieving universal antiretroviral therapy (ART) coverage. Many of the public-sector HIV clinics operating within tertiary facilities, that were the first to provide ART in the country, have reached maximum patient capacity. Decentralization or "down-referral" (wherein ART patients deemed stable on therapy are referred to their closest Primary Health Clinics (PHCs) for treatment follow-up) is being used as a possible alternative of ART delivery care. This cross-sectional qualitative study investigates attitudes towards down-referral of ART delivery care among patients currently receiving care in a centralized tertiary HIV clinic.</p> <p>Methods</p> <p>Ten focus group discussions (FGDs) with 76 participants were conducted in early 2008 amongst ART patients initiated and receiving care for more than 3 months in the tertiary HIV clinic study site. Eligible individuals were invited to participate in FGDs involving 6-9 participants, and lasting approximately 1-2 hours. A trained moderator used a discussion topic guide to investigate the main issues of interest including: advantages and disadvantages of down-referral, potential motivating factors and challenges of down-referral, assistance needs from the transferring clinic as well as from PHCs.</p> <p>Results</p> <p>Advantages include closeness to patients' homes, transport and time savings. However, patients favour a centralized service for the following reasons: less stigma, patients established relationship with the centralized clinic, and availability of ancillary services. Most FGDs felt that for down-referral to occur there needed to be training of nurses in patient-provider communication.</p> <p>Conclusion</p> <p>Despite acknowledging the down-referral advantages of close proximity and lower transport costs, many participants expressed concerns about lack of trained HIV clinical staff, negative patient interactions with nurses, limited confidentiality and stigma. There was consensus that training of nurses and improved health systems at the local clinics were needed if successful down-referral was to take place.</p

Community-based directly observed therapy (DOT) versus clinic DOT for tuberculosis: a systematic review and meta-analysis of comparative effectiveness.

Background: Directly observed therapy (DOT), as recommended by the World Health Organization, is used in many countries to deliver tuberculosis (TB) treatment. The effectiveness of community-based (CB DOT) versus clinic DOT has not been adequately assessed to date. We compared TB treatment outcomes of CB DOT (delivered by community health workers or community volunteers), with those achieved through conventional clinic DOT. Methods: We performed a systematic review and meta-analysis of studies before 9 July 2014 comparing treatment outcomes of CB DOT and clinic DOT. The primary outcome was treatment success; the secondary outcome was loss to follow-up. Results: Eight studies were included comparing CB DOT to clinic DOT, one a randomised controlled trial. CB DOT outperformed clinic DOT treatment success (pooled odds ratio (OR) of 1.54, 95% confidence interval (CI) 1.01 – 2.36, p = 0.046, I2 heterogeneity 84%). No statistically significant difference was found between the two DOT modalities for loss to follow-up (pooled OR 0.86, 95% CI 0.48 to 1.55, p = 0.62, I2 83%). Conclusions: Based on this systematic review, CB DOT has a higher treatment success compared to clinic DOT. However, as only one study was a randomised controlled trial, the findings have to be interpreted with caution

HIV sero-prevalence among tuberculosis patients in Kenya

Objective: To determine HIV seroprevalence among tuberculosis patients and the burden of HlV attributable tuberculosis among notified patients in Kenya.Design: A cross-sectional anonymous unlinked HlV seroprevalence survey.Setting: Tuberculosis diagnostic clinics of the National Leprosy Tuberculosis Programme in 19 districts.Subjects: One thousand nine hundred and fifty two newly notified tuberculosis patients.Interventions: Selection and registration of eligible subjects followed by obtaining 5ml of full blood for haemoglobin testing and separation of serum for HIV testing by ELISA.Main outcome measures: HlV seroprevalence per district and burden of HIV attributable tuberculosis among tuberculosis patients.Results: A total of 1,952 eligible patients were ended. The weighted seroprevalence in the sample was 40.7% (range 11.8-79.6% per district). The seroprevalence was significantly higher among females and patients with sputum-smear negative tuberculosis. Chronic diarrhoea, female sex, oral thrush and a negative sputum were independent risk factors for HIV infection. The Odds ratio for HIV infection in female tuberculosis patients aged 15-44 years, was 5.6 (95% CI 4.5-6.9) compared with ante-natal clinic attenders. The population attributable risk was 0.22 in 1994.Conclusion: The HlV epidemic has had a profound impact on the tuberculosis epidemic in Kenya and explains about 41% of the 94.5% increase of registered patients in the period 1990-1994 and 20% of all registered patients in 1994. Repetition of the survey with inclusion of a more representative control group from the general population may provide a more accurate estimation of the burden of HIV attributable tuberculosis
