HIV policy and implementation: a national policy review and an implementation case study of a rural area of northern Malawi.

Malawi is a global leader in the design and implementation of progressive HIV policies. However, there continues to be substantial attrition of people living with HIV across the "cascade" of HIV services from diagnosis to treatment, and program outcomes could improve further. Ability to successfully implement national HIV policy, especially in rural areas, may have an impact on consistency of service uptake. We reviewed Malawian policies and guidelines published between 2003 and 2013 relating to accessibility of adult HIV testing, prevention of mother-to-child transmission and HIV care and treatment services using a policy extraction tool, with gaps completed through key informant interviews. A health facility survey was conducted in six facilities serving the population of a demographic surveillance site in rural northern Malawi to investigate service-level policy implementation. Survey data were analyzed using descriptive statistics. Policy implementation was assessed by comparing policy content and facility practice using pre-defined indicators covering service access: quality of care, service coordination and patient tracking, patient support, and medical management. ART was rolled out in Malawi in 2004 and became available in the study area in 2005. In most areas, practices in the surveyed health facilities complied with or exceeded national policy, including those designed to promote rapid initiation onto treatment, such as free services and task-shifting for treatment initiation. However, policy and/or practice were/was lacking in certain areas, in particular those strategies to promote retention in HIV care (e.g., adherence monitoring and home-based care). In some instances, though, facilities implemented alternative progressive practices aimed at improving quality of care and encouraging adherence. While Malawi has formulated a range of progressive policies aiming to promote rapid initiation onto ART, increased investment in policy implementation strategies and quality service delivery, in particular to promote long-term retention on treatment may improve outcomes further.

Uptake, Accuracy, Safety, and Linkage into Care over Two Years of Promoting Annual Self-Testing for HIV in Blantyre, Malawi: A Community-Based Prospective Study.

BACKGROUND: Home-based HIV testing and counselling (HTC) achieves high uptake, but is difficult and expensive to implement and sustain. We investigated a novel alternative based on HIV self-testing (HIVST). The aim was to evaluate the uptake of testing, accuracy, linkage into care, and health outcomes when highly convenient and flexible but supported access to HIVST kits was provided to a well-defined and closely monitored population. METHODS AND FINDINGS: Following enumeration of 14 neighbourhoods in urban Blantyre, Malawi, trained resident volunteer-counsellors offered oral HIVST kits (OraQuick ADVANCE Rapid HIV-1/2 Antibody Test) to adult (≥16 y old) residents (n = 16,660) and reported community events, with all deaths investigated by verbal autopsy. Written and demonstrated instructions, pre- and post-test counselling, and facilitated HIV care assessment were provided, with a request to return kits and a self-completed questionnaire. Accuracy, residency, and a study-imposed requirement to limit HIVST to one test per year were monitored by home visits in a systematic quality assurance (QA) sample. Overall, 14,004 (crude uptake 83.8%, revised to 76.5% to account for population turnover) residents self-tested during months 1-12, with adolescents (16-19 y) most likely to test. 10,614/14,004 (75.8%) participants shared results with volunteer-counsellors. Of 1,257 (11.8%) HIV-positive participants, 26.0% were already on antiretroviral therapy, and 524 (linkage 56.3%) newly accessed care with a median CD4 count of 250 cells/µl (interquartile range 159-426). HIVST uptake in months 13-24 was more rapid (70.9% uptake by 6 mo), with fewer (7.3%, 95% CI 6.8%-7.8%) positive participants. Being "forced to test", usually by a main partner, was reported by 2.9% (95% CI 2.6%-3.2%) of 10,017 questionnaire respondents in months 1-12, but satisfaction with HIVST (94.4%) remained high. No HIVST-related partner violence or suicides were reported. HIVST and repeat HTC results agreed in 1,639/1,649 systematically selected (1 in 20) QA participants (99.4%), giving a sensitivity of 93.6% (95% CI 88.2%-97.0%) and a specificity of 99.9% (95% CI 99.6%-100%). Key limitations included use of aggregate data to report uptake of HIVST and being unable to adjust for population turnover. CONCLUSIONS: Community-based HIVST achieved high coverage in two successive years and was safe, accurate, and acceptable. Proactive HIVST strategies, supported and monitored by communities, could substantially complement existing approaches to providing early HIV diagnosis and periodic repeat testing to adolescents and adults in high-HIV settings.

A comparative analysis of national HIV policies in six African countries with generalized epidemics.

OBJECTIVE: To compare national human immunodeficiency virus (HIV) policies influencing access to HIV testing and treatment services in six sub-Saharan African countries. METHODS: We reviewed HIV policies as part of a multi-country study on adult mortality in sub-Saharan Africa. A policy extraction tool was developed and used to review national HIV policy documents and guidelines published in Kenya, Malawi, South Africa, Uganda, the United Republic of Tanzania and Zimbabwe between 2003 and 2013. Key informant interviews helped to fill gaps in findings. National policies were categorized according to whether they explicitly or implicitly adhered to 54 policy indicators, identified through literature and expert reviews. We also compared the national policies with World Health Organization (WHO) guidance. FINDINGS: There was wide variation in policies between countries; each country was progressive in some areas and not in others. Malawi was particularly advanced in promoting rapid initiation of antiretroviral therapy. However, no country had a consistently enabling policy context expected to increase access to care and prevent attrition. Countries went beyond WHO guidance in certain areas and key informants reported that practice often surpassed policy. CONCLUSION: Evaluating the impact of policy differences on access to care and health outcomes among people living with HIV is challenging. Certain policies will exert more influence than others and official policies are not always implemented. Future research should assess the extent of policy implementation and link these findings with HIV outcomes.

Strategies for monitoring and evaluation of resource-limited national antiretroviral therapy programs: the two-phase design.

BACKGROUND: In resource-limited settings, monitoring and evaluation (M&E) of antiretroviral treatment (ART) programs often relies on aggregated facility-level data. Such data are limited, however, because of the potential for ecological bias, although collecting detailed patient-level data is often prohibitively expensive. To resolve this dilemma, we propose the use of the two-phase design. Specifically, when the outcome of interest is binary, the two-phase design provides a framework within which researchers can resolve ecological bias through the collection of patient-level data on a sub-sample of individuals while making use of the routinely collected aggregated data to obtain potentially substantial efficiency gains. METHODS: Between 2005-2007, the Malawian Ministry of Health conducted a one-time cross-sectional survey of 82,887 patients registered at 189 ART clinics. Using these patient data, an aggregated dataset is constructed to mimic the type of data that it routinely available. A hypothetical study of risk factors for patient outcomes at 6 months post-registration is considered. Analyses are conducted based on: (i) complete patient-level data; (ii) aggregated data; (iii) a hypothetical case-control study; (iv) a hypothetical two-phase study stratified on clinic type; and, (v) a hypothetical two-phase study stratified on clinic type and registration year. A simulation study is conducted to compare statistical power to detect an interaction between clinic type and year of registration across the designs. RESULTS: Analyses and conclusions based solely on aggregated data may suffer from ecological bias. Collecting and analyzing patient data using either a case-control or two-phase design resolves ecological bias to provide valid conclusions. To detect the interaction between clinic type and year of registration, the case-control design would require a prohibitively large sample size. In contrast, a two-phase design that stratifies on clinic and year of registration achieves greater than 85% power with as few as 1,000 patient samples. CONCLUSIONS: Two-phase designs have the potential to augment current M&E efforts in resource-limited settings by providing a framework for the collection and analysis of patient data. The design is cost-efficient in the sense that it often requires far fewer patients to be sampled when compared to standard designs.

Effect of optional home initiation of HIV care following HIV self-testing on antiretroviral therapy initiation among adults in Malawi: a randomized clinical trial.

IMPORTANCE: Self-testing for HIV infection may contribute to early diagnosis of HIV, but without necessarily increasing antiretroviral therapy (ART) initiation. OBJECTIVE: To investigate whether offering optional home initiation of HIV care after HIV self-testing might increase demand for ART initiation, compared with HIV self-testing accompanied by facility-based services only. DESIGN, SETTING, AND PARTICIPANTS: Cluster randomized trial conducted in Blantyre, Malawi, between January 30 and November 5, 2012, using restricted 1:1 randomization of 14 community health worker catchment areas. Participants were all adult (≥16 years) residents (n = 16,660) who received access to home HIV self-testing through resident volunteers. This was a second-stage randomization of clusters allocated to the HIV self-testing group of a parent trial. INTERVENTIONS: Clusters were randomly allocated to facility-based care or optional home initiation of HIV care (including 2 weeks of ART if eligible) for participants reporting positive HIV self-test results. MAIN OUTCOMES AND MEASURES: The preplanned primary outcome compared between groups the proportion of all adult residents who initiated ART within the first 6 months of HIV self-testing availability. Secondary outcomes were uptake of HIV self-testing, reporting of positive HIV self-test results, and rates of loss from ART at 6 months. RESULTS: A significantly greater proportion of adults in the home group initiated ART (181/8194, 2.2%) compared with the facility group (63/8466, 0.7%; risk ratio [RR], 2.94, 95% CI, 2.10-4.12; P < .001). Uptake of HIV self-testing was high in both the home (5287/8194, 64.9%) and facility groups (4433/8466, 52.7%; RR, 1.23; 95% CI, 0.96-1.58; P = .10). Significantly more adults reported positive HIV self-test results in the home group (490/8194 [6.0%] vs the facility group, 278/8466 [3.3%]; RR, 1.86; 95% CI, 1.16-2.97; P = .006). After 6 months, 52 of 181 ART initiators (28.7%) and 15 of 63 ART initiators (23.8%) in the home and facility groups, respectively, were lost from ART (adjusted incidence rate ratio, 1.18; 95% CI, 0.62-2.25, P = .57). CONCLUSIONS AND RELEVANCE: Among Malawian adults offered HIV self-testing, optional home initiation of care compared with standard HIV care resulted in a significant increase in the proportion of adults initiating ART. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT01414413.

Development and validation of a global positioning system-based "map book" system for categorizing cluster residency status of community members living in high-density urban slums in Blantyre, Malawi.

A significant methodological challenge in implementing community-based cluster-randomized trials is how to accurately categorize cluster residency when data are collected at a site distant from households. This study set out to validate a map book system for use in urban slums with no municipal address systems, where classification has been shown to be inaccurate when address descriptions were used. Between April and July 2011, 28 noncontiguous clusters were demarcated in Blantyre, Malawi. In December 2011, antiretroviral therapy initiators were asked to identify themselves as cluster residents (yes/no and which cluster) by using map books. A random sample of antiretroviral therapy initiators was used to validate map book categorization against Global Positioning System coordinates taken from participants' households. Of the 202 antiretroviral therapy initiators, 48 (23.8%) were categorized with the map book system as in-cluster residents and 147 (72.8%) as out-of-cluster residents, and 7 (3.4%) were unsure. Agreement between map books and the Global Positioning System was 100% in the 20 adults selected for validation and was 95.0% (κ = 0.96, 95% confidence interval: 0.84, 1.00) in an additional 20 in-cluster residents (overall κ = 0.97, 95% confidence interval: 0.90, 1.00). With map books, cluster residents were classified rapidly and accurately. If validated elsewhere, this approach could be of widespread value in that it would enable accurate categorization without home visits.

Suboptimal patterns of provider initiated HIV testing and counselling, antiretroviral therapy eligibility assessment and referral in primary health clinic attendees in Blantyre, Malawi.

OBJECTIVE: To understand reasons for suboptimal and delayed uptake of antiretroviral therapy (ART) by describing the patterns of HIV testing and counselling (HTC) and outcomes of ART eligibility assessments in primary clinic attendees. METHODS: All clinic attendances and episodes of HTC were recorded at two clinics in Blantyre. A cohort of newly diagnosed HIV-positive adults (>15 years) was recruited and exit interviews undertaken. Logistic regression models were constructed to investigate factors associated with referral to start ART. Qualitative interviews were conducted with providers and patients. RESULTS: There were 2398 episodes of HTC during 18,021 clinic attendances (13.3%) between January and April 2011. The proportion of clinic attendees undergoing HTC was lowest in non-pregnant women (6.3%) and men (8.5%), compared with pregnant women (47.2%). Men had more advanced HIV infection than women (79.7% WHO stage 3 or 4 vs. 56.4%). Problems with WHO staging and access to CD4 counts affected ART eligibility assessments; only 48% completed ART eligibility assessment, and 54% of those reporting WHO stage 3/4 illnesses were not referred to start ART promptly. On multivariate analysis, HIV-positive pregnant women were significantly less likely to be referred directly for ART initiation (adjusted OR: 0.29, 95% CI: 0.13-0.63). CONCLUSIONS: These data show that provider-initiated testing and counselling (PITC) has not yet been fully implemented at primary care clinics. Suboptimal ART eligibility assessments and referral (reflecting the difficulties of WHO staging in primary care) mean that simplified eligibility assessment tools are required to reduce unnecessary delay and attrition in the pre-ART period. Simplified initiation criteria for pregnant women, as being introduced in Malawi, should improve linkage to ART.

Improving data quality and supervision of antiretroviral therapy sites in Malawi: an application of Lot Quality Assurance Sampling.

BACKGROUND: High quality program data is critical for managing, monitoring, and evaluating national HIV treatment programs. By 2009, the Malawi Ministry of Health had initiated more than 270,000 patients on HIV treatment at 377 sites. Quarterly supervision of these antiretroviral therapy (ART) sites ensures high quality care, but the time currently dedicated to exhaustive record review and data cleaning detracts from other critical components. The exhaustive record review is unlikely to be sustainable long term because of the resources required and increasing number of patients on ART. This study quantifies the current levels of data quality and evaluates Lot Quality Assurance Sampling (LQAS) as a tool to prioritize sites with low data quality, thus lowering costs while maintaining sufficient quality for program monitoring and patient care. METHODS: In January 2010, a study team joined supervision teams at 19 sites purposely selected to reflect the variety of ART sites. During the exhaustive data review, the time allocated to data cleaning and data discrepancies were documented. The team then randomly sampled 76 records from each site, recording secondary outcomes and the time required for sampling. RESULTS: At the 19 sites, only 1.2% of records had discrepancies in patient outcomes and 0.4% in treatment regimen. However, data cleaning took 28.5 hours in total, suggesting that data cleaning for all 377 ART sites would require over 350 supervision-hours quarterly. The LQAS tool accurately identified the sites with the low data quality, reduced the time for data cleaning by 70%, and allowed for reporting on secondary outcomes. CONCLUSIONS: Most sites maintained high quality records. In spite of this, data cleaning required significant amounts of time with little effect on program estimates of patient outcomes. LQAS conserves resources while maintaining sufficient data quality for program assessment and management to allow for quality patient care.

The uptake and accuracy of oral kits for HIV self-testing in high HIV prevalence setting: a cross-sectional feasibility study in Blantyre, Malawi.

BACKGROUND: Although HIV testing and counseling (HTC) uptake has increased dramatically in Africa, facility-based services are unlikely to ever meet ongoing need to the full. A major constraint in scaling up community and home-based HTC services is the unacceptability of receiving HTC from a provider known personally to prospective clients. We investigated the potential of supervised oral HIV self-testing from this perspective. METHODS AND FINDINGS: Adult members of 60 households and 72 members of community peer groups in urban Blantyre, Malawi, were selected using population-weighted random cluster sampling. Participants were offered self-testing plus confirmatory HTC (parallel testing with two rapid finger-prick blood tests), standard HTC alone, or no testing. 283 (95.6%) of 298 selected adults participated, including 136 (48.0%) men. 175 (61.8%) had previously tested (19 known HIV positive), although only 64 (21.5%) within the last year. HIV prevalence was 18.5%. Among 260 (91.9%) who opted to self-test after brief demonstration and illustrated instructions, accuracy was 99.2% (two false negatives). Although 98.5% rated the test "not hard at all to do," 10.0% made minor procedural errors, and 10.0% required extra help. Most participants indicated willingness to accept self-test kits, but not HTC, from a neighbor (acceptability 94.5% versus 46.8%, p = 0.001). CONCLUSIONS: Oral supervised self-testing was highly acceptable and accurate, although minor errors and need for supervisory support were common. This novel option has potential for high uptake at local community level if it can be supervised and safely linked to counseling and care.

Operational research in Malawi: making a difference with cotrimoxazole preventive therapy in patients with tuberculosis and HIV.

BACKGROUND: In Malawi, high case fatality rates in patients with tuberculosis, who were also co-infected with HIV, and high early death rates in people living with HIV during the initiation of antiretroviral treatment (ART) adversely impacted on treatment outcomes for the national tuberculosis and ART programmes respectively. This article i) discusses the operational research that was conducted in the country on cotrimoxazole preventive therapy, ii) outlines the steps that were taken to translate these findings into national policy and practice, iii) shows how the implementation of cotrimoxazole preventive therapy for both TB patients and HIV-infected patients starting ART was associated with reduced death rates, and iv) highlights lessons that can be learnt for other settings and interventions. DISCUSSION: District and facility-based operational research was undertaken between 1999 and 2005 to assess the effectiveness of cotrimoxazole preventive therapy in reducing death rates in TB patients and subsequently in patients starting ART under routine programme conditions. Studies demonstrated significant reductions in case fatality in HIV-infected TB patients receiving cotrimoxazole and in HIV-infected patients about to start ART. Following the completion of research, the findings were rapidly disseminated nationally at stakeholder meetings convened by the Ministry of Health and internationally through conferences and peer-reviewed scientific publications. The Ministry of Health made policy changes based on the available evidence, following which there was countrywide distribution of the updated policy and guidelines. Policy was rapidly moved to practice with the development of monitoring tools, drug procurement and training packages. National programme performance improved which showed a significant decrease in case fatality rates in TB patients as well as a reduction in early death in people with HIV starting ART. SUMMARY: Key lessons for moving this research endeavour through to policy and practice were the importance of placing operational research within the programme, defining relevant questions, obtaining "buy-in" from national programme staff at the beginning of projects and having key actors or "policy entrepreneurs" to push forward the policy-making process. Ultimately, any change in policy and practice has to benefit patients, and the ultimate judge of success is whether treatment outcomes improve or not.

Burden of cryptococcal meningitis in Malawi.

There is little information about the national burden of cryptococcal meningitis (CM) in African countries affected by the HIV/AIDS epidemic. From April 2005 onwards, we used national supervision visits of all health facilities that provided antiretroviral therapy to collect data on the number of new patients diagnosed and treated for CM in the previous quarters - using mainly fluconazole registers. For two 12-month reporting periods, there were 2125 and 2464 patients suffering from CM, giving an estimated annual incidence of 2.2% and 2.6%, respectively, of those infected with HIV in Malawi. Between 40-50% of all patients with CM were diagnosed and treated at central hospitals; no more than 1% were diagnosed and treated at smaller antiretroviral therapy sites. These data are useful for quantifying the need for better diagnostic reagents and antifungal drugs.

Early warning indicators for HIV drug resistance in Malawi.

BACKGROUND: Malawi started rapid scale-up of antiretroviral therapy (ART) in 2004 and by December 2006 had initiated over 85,000 patients on treatment. Early warning indicator (EWI) reports can help to minimize the risk of emerging drug resistance. METHODS: Data collected during the routine quarterly supervision of 103 public sector sites was used to compile the first EWI report for HIV drug resistance (HIVDR) in Malawi, reflecting outcomes for October to December 2006. RESULTS: All sites reach the World Health Organization (WHO) targets for prescribing practices and drug supply continuity. The target for adherence was achieved by 85% of sites and 84% achieved the target for minimizing treatment defaults; however, less than half of all sites reach the WHO target for patient retention. CONCLUSIONS: These results emphasize the importance of defaulter tracing and initiating treatment earlier in the course of HIV infection. As part of a comprehensive HIVDR monitoring programme, the Ministry of Health plans for on-going tracking of these indicators, as well as special data collection from the private sector. Plans are also underway to gather information on other recommended indicators that are not collected during routine supervision.

Assessing the quality of data aggregated by antiretroviral treatment clinics in Malawi.

PROBLEM: As national antiretroviral treatment (ART) programmes scale-up, it is essential that information is complete, timely and accurate for site monitoring and national planning. The accuracy and completeness of reports independently compiled by ART facilities, however, is often not known. APPROACH: This study assessed the quality of quarterly aggregate summary data for April to June 2006 compiled and reported by ART facilities ("site report") as compared to the "gold standard" facility summary data compiled independently by the Ministry of Health supervision team ("supervision report"). Completeness and accuracy of key case registration and outcome variables were compared. Data were considered inaccurate if variables from the site reports were missing or differed by more than 5% from the supervision reports. Additionally, we compared the national summaries obtained from the two data sources. LOCAL SETTING: Monitoring and evaluation of Malawi's national ART programme is based on WHO's recommended tools for ART monitoring. It includes one master card for each ART patient and one patient register at each ART facility. Each quarter, sites complete cumulative cohort analyses and teams from the Ministry of Health conduct supervisory visits to all public sector ART sites to ensure the quality of reported data. RELEVANT CHANGES: Most sites had complete case registration and outcome data; however many sites did not report accurate data for several critical data fields, including reason for starting, outcome and regimen. The national summary using the site reports resulted in a 12% undercount in the national total number of persons on first-line treatment. Several facility-level characteristics were associated with data quality. LESSONS LEARNED: While many sites are able to generate complete data summaries, the accuracy of facility reports is not yet adequate for national monitoring. The Ministry of Health and its partners should continue to identify and support interventions such as supportive supervision to build sites' capacity to maintain and compile quality data to ensure that accurate information is available for site monitoring and national planning.

Different delivery models for antiretroviral therapy in sub-Saharan Africa in the context of 'universal access'.

In 10 years, in line with the concept of universal access, 25 million HIV-infected patients in sub-Saharan Africa might be on antiretroviral therapy (ART). There are different models of ART delivery, from the individualised, medical approach to the simple, public health approach, both having distinct advantages and disadvantages. This mini-review highlights the essential components of both models and argues that, whatever the mix of different models in a country, both must be underpinned by similar core principles so that uninterrupted drug supplies, patient adherence to therapy and compliance with follow up are assured. Failure to do otherwise is to court disaster.

World Health Organization Clinical Stage 3 disease conditions in HIV-infected patients who start antiretroviral therapy in Malawi.

There is little information about disease conditions that are diagnosed in patients diagnosed as having World Health Organization Clinical Stage 3 HIV who are started on antiretroviral therapy (ART) in Africa. We therefore conducted an audit in the central region of Malawi of patients registered for ART between January and September 2006. There were 4299 patients in Stage 3 of whom 4154 had data about their disease conditions. Only one condition was listed for 3880 patients. Of these, 1892 (48.8%) had unexplained weight loss, chronic fever or chronic diarrhoea, 822 (21.2%) had active/previous tuberculosis (TB) and 671 (17.3%) had a severe presumed bacterial infection. No patient was diagnosed as having haematological abnormalities. Nearly half the patients started on ART had a symptomatic, unspecified disease, (which may be obscuring important pathologies such as TB) and almost no laboratory assessment had taken place before the commencement of ART. These two areas need to be addressed in order to improve the management of patients starting on ART.

Outcomes of patients with Kaposi's sarcoma who start antiretroviral therapy under routine programme conditions in Malawi.

AIDS-associated Kaposi's sarcoma (KS) is the most common AIDS-related malignancy in sub-Saharan Africa, with a generally unfavourable prognosis. We report on six-month and 12-month cohort treatment outcomes of human immunodeficiency virus (HIV)-positive KS patients and HIV-positive non-KS patients treated with antiretroviral therapy (ART) in public sector facilities in Malawi. Data were collected from standardized antiretroviral (ARV) patient master cards and ARV patient registers. Between July and September 2005, 7905 patients started ART-488 (6%) with a diagnosis of KS and 7417 with a non-KS diagnosis. Between January and March 2005, 4580 patients started ART-326 (7%) with a diagnosis of KS and 4254 with a non-KS diagnosis. At six-months and 12-months, significantly fewer KS patients were alive and significantly more had died or defaulted compared to non-KS patients. HIV-positive KS patients on ART in Malawi have worse outcomes than other patients on ART. Methods designed to improve these outcomes must be found.

A national survey of prisoners on antiretroviral therapy in Malawi: access to treatment and outcomes on therapy.

BACKGROUND: Malawi is making good progress scaling up antiretroviral therapy (ART), but we do not know the levels of access of high-risk, disadvantaged groups such as prisoners. The aim of this study was to measure access and treatment outcomes of prisoners on ART at the national level. METHODOLOGY: A retrospective cohort study was conducted examining patient follow-up records from all 103 public sector ART clinics in Malawi, and observations were censored on 31 December, 2006. RESULTS: By 31 December, 2006, a total of 81,821 patients had been started on ART. Of these, 103 (0.13%) were prisoners. At ART initiation, 93% of prisoners were in World Health Organization (WHO) clinical stage 3 or 4 while 7% started in stage 1 or 2 with a CD4-lymphocyte count of < or =250/mm3. Treatment outcomes by the end of December 2006 were as follows: 66 (64%) alive and on ART at their registration facility; 9 (9%) dead; 8 (8%) lost to follow-up; and 20 (19%) transferred out to another facility. The probability of being alive and on ART at 6 and 12 months was 82.5% and 77.7%. CONCLUSIONS: In spite of the rapid scale-up of ART, only a small number of HIV-positive prisoners had accessed ART by the end of 2006. Treatment outcomes were good. Initiatives are now needed to improve access to HIV testing and ART in Malawi's prisons.

Risk factors for early mortality in children on adult fixed-dose combination antiretroviral treatment in a central hospital in Malawi.

OBJECTIVES: In children aged less than 15 years, to determine the cumulative proportion of deaths occurring within 3 and 6 months of starting split-tablet adult fixed-dose combination antiretroviral therapy (ART) and to identify risk factors associated with early deaths. DESIGN: A retrospective cohort analysis. METHODS: Data were collected and analysed from ART patient master cards and the ART register of all children registered for treatment between July 2004 and September 2006 in the ART clinic at Mzuzu Central Hospital, northern Malawi. RESULTS: A total of 439 children started on ART, of whom 220 (50%) were male; 37 (8%) were aged less than 18 months, 172 (39%) 18 months to 5 years, and 230 (52%) were 6-14 years. By September 2006, 49 children (11%) had died, of whom 35 (71%) died by 3 months and 44 (89%) by 6 months. The cumulative incidence of death at 3, 6, 12 and 24 months after ART was 8, 12, 13 and 15%, respectively. After multivariate analysis, being in World Health Organization clinical stage 4, having severe wasting and severe immunodeficiency were factors significantly associated with 3-month mortality and 6-month mortality, respectively. CONCLUSION: Although children do well on ART, there is high early mortality. Scaling up HIV testing and simple diagnostic tests for infants and children, expanding routine provision of cotrimoxazole prophylaxis, and investigating the role of nutritional interventions are three measures that, if implemented and expanded countrywide, may improve ART outcomes.

Risk factors for high early mortality in patients on antiretroviral treatment in a rural district of Malawi.

OBJECTIVES: Among adults started on antiretroviral treatment (ART) in a rural district hospital (a) to determine the cumulative proportion of deaths that occur within 3 and 6 months of starting ART, and (b) to identify risk factors that may be associated with such mortality. DESIGN AND SETTING: A cross-sectional analytical study set in Thyolo district, Malawi. METHODS: Over a 2-year period (April 2003 to April 2005) mortality within the first 3 and 6 months of starting ART was determined and risk factors were examined. RESULTS: A total of 1507 individuals (517 men and 990 women), whose median age was 35 years were included in the study. There were a total of 190 (12.6%) deaths on ART of which 116 (61%) occurred within the first 3 months (very early mortality) and 150 (79%) during the first 6 months of initiating ART. Significant risk factors associated with such mortality included WHO stage IV disease, a baseline CD4 cell count under 50 cells/mul and increasing grades of malnutrition. A linear trend in mortality was observed with increasing grades of malnutrition (chi for trend = 96.1, P
