Causes of death and associated factors over a decade of follow-up in a cohort of people living with HIV in rural Tanzania. BMC Infect Dis 2022; 22:37. [PMID: 34991496 PMCID: PMC8739638 DOI: 10.1186/s12879-021-06962-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2021] [Accepted: 12/01/2021] [Indexed: 11/10/2022] Open
Abstract
Background Nearly half of HIV-related deaths occur in East and Southern Africa, yet data on causes of death (COD) are scarce. We determined COD and associated factors among people living with HIV (PLHIV) in rural Tanzania. Methods PLHIV attending the Chronic Diseases Clinic of Ifakara, Morogoro are invited to enrol in the Kilombero and Ulanga Antiretroviral Cohort (KIULARCO). Among adults (≥ 15 years) enrolled in 2005–2018, with follow-up through April 2019, we classified COD in comprehensive classes and as HIV- or non-HIV-related. In the subset of participants enrolled in 2013–2018 (when data were more complete), we assessed cause-specific mortality using cumulative incidences, and associated factors using proportional hazards models. Results Among 9871 adults (65% female, 26% CD4 count < 100 cells/mm3), 926 (9%) died, among whom COD were available for 474 (51%), with missing COD mainly in earlier years. The most common COD were tuberculosis (N = 127, 27%), non-AIDS-related infections (N = 72, 15%), and other AIDS-related infections (N = 59, 12%). Cardiovascular and renal deaths emerged as important COD in later calendar years, with 27% of deaths in 2018 attributable to cardiovascular causes. Most deaths (51%) occurred within the first six months following enrolment. Among 3956 participants enrolled in 2013–2018 (N = 203 deaths, 200 with COD ascertained), tuberculosis persisted as the most common COD (25%), but substantial proportions of deaths from six months after enrolment onwards were attributable to renal (14%), non-AIDS-related infections (13%), other AIDS-related infections (10%) and cardiovascular (10%) causes. Factors associated with higher HIV-related mortality were sex, younger age, living in Ifakara town, HIV status disclosure, hospitalisation, not being underweight, lower CD4 count, advanced WHO stage, and gaps in care. Factors associated with higher non-HIV-related mortality included not having an HIV-positive partner, lower CD4 count, advanced WHO stage, and gaps in care. Conclusion Incidence of HIV-related mortality was higher than that of non-HIV-related mortality, even in more recent years, likely due to late presentation. Tuberculosis was the leading specific COD identified, particularly soon after enrolment, while in later calendar years cardiovascular and renal causes emerged as important, emphasising the need for improved screening and management.

Abstract
The Joint United Nations Programme on HIV/AIDS (UNAIDS) and partners launched the 90-90-90 targets. We used Tanzania HIV Impact Survey (THIS) data in 2017 to study the barriers to achieve 90-90-90 targets. THIS was a population-based survey with a stratified multistage stage sampling design. We used weighted logistic regression to associate three targets with socio-demographics, HIV-related discrimination, fear and shame. We defined HIV awareness by a combination of self-reported of HIV status positive and detected antiretroviral (ARV) in blood among PLWH. On ARV was defined as those who self-reported among awareness. Viral load suppression was defined as 400 copies/ml or less in the blood sample. The three targets were estimated at 61-90-85 in Tanzania from the weighted analysis. The first target was far from being achieved. The weighted regression showed that being female, having attained higher education, married, having insurance, and living in urban areas were associated with a high likelihood of having ever tested for HIV. The results indicated that intervention programmes in Tanzania should focus on the first target. Intervention programmes should be designed for each target separately. Integrated strategies in the context of low and middle-income countries are needed to achieve these targets.

Cervical Cancer Screening among Women Receiving Antiretroviral Therapy in a Resource-Limited Environment. Asian Pac J Cancer Prev 2020; 21:2035-2045. [PMID: 32711430 PMCID: PMC7573407 DOI: 10.31557/apjcp.2020.21.7.2035] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/29/2020] [Indexed: 12/31/2022] Open
Abstract
Background: Cervical cancer is among the most prevalent cancer among women worldwide and women living with HIV are at increased risk, especially in a resource-limited environment. Objective: This study aimed to determine levels of awareness, knowledge, uptake, and willingness to screen for cervical cancer among women receiving care in an HIV clinic at Dodoma Regional Referral Hospital (DRRH), Tanzania. Methods: Data were collected for a period of three weeks from July 21 to August 11, 2017 using a mobile phone data collection App. A total of 421 Women aged 18-50 years old were included in the study. Results: Majority of the women interviewed (n=306, 73%) were aware of cervical cancer. Among those who were aware, 84% (n=257) did not recall ever being screened for cervical cancer, and majority had a poor knowledge of cervical cancer. Educational level completed (p=0.01), income per month (p=0.02), age group (p<0.0001), and area of residence (p<0.0001) were all significantly associated to awareness of cervical cancer. Most of the women who have never screened (n=231, 91%) expressed willingness to be screened. Prior uptake of cervical cancer screening was associated with number of live births (p=0.001) and area of residence (p=0.04). And Willingness to screen was significantly associated with age groups (p=0.03) and the number of live births (p=0.03). Moreover, we found that younger age and urban residence was positively associated with awareness and uptake of cervical cancer screening. Willingness was found to decrease as age increased. Conclusion: The study found that despite older women’s higher risk of cervical cancer, those who indicated willingness to screen were younger. Additional education, health promotion, and integration of cervical cancer screening services is needed to improve cervical cancer awareness and screening uptake at the HIV clinic.

Knowledge and perception on type2 diabetes and hypertension among HIV clients utilizing care and treatment services: a cross sectional study from Mbeya and Dar es Salaam regions in Tanzania. BMC Public Health 2018; 18:928. [PMID: 30055591 PMCID: PMC6064130 DOI: 10.1186/s12889-018-5639-7] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2018] [Accepted: 05/30/2018] [Indexed: 01/31/2023] Open
Abstract
BACKGROUND Type2 Diabetes and Hypertension (T2DM/HTN) have become serious threats to the health and socio-economic development in the developing countries. People living with HIV (PLHIV) infection are more vulnerable of developing T2DM/HTN due to HIV infection itself and antiretroviral treatments. The situation is worse when behavioral and biological risk factors are pervasive to PLHIV. Despite this vicious circle; information on the level of knowledge and perception regarding prevention of T2DM/HTN, risks factors and associated complications among PLHIV is not well documented in Tanzania. The aim of this paper was assess the level of T2DM/HTN knowledge and perception among PLHIV and utilizing care and treatment clinic (CTC) services. METHODS A cross-sectional study was conducted in randomly selected 12 CTCs between October 2011 and February 2012. Data on demographic characteristics, type 2 diabetes and hypertension knowledge and perception were collected from the study participants. RESULTS Out of 754 PLHIV and receiving HIV services at the selected CTCs, 671 (89%) consented for the study. Overall 276/671(41.1%) respondents had low knowledge on type2 diabetes and hypertension risk factors and their associated complications. Locality (rural) (AOR = 2.2; 95%CI 1.4-3.4) and never/not recalling if ever measured blood glucose in life (AOR = 2.3; 95%CI 1.1-5.7) were significant determinants of low knowledge among clients on ART. Being currently not having HIV and T2DM/HTN co-morbidities (AOR = 2.2; 95%CI 1.2-4.9) was the only determinant of low knowledge among ART Naïve clients. With regard to perception, 293/671(43.7%) respondents had negative perception on diabetes and hypertension prevention. Sex (female) (AOR = 2.0, 95%CI 1.2-2.9), being aged < 40 years (AOR = 1.6; 95%CI 1.1-2.5) and education (primary/no formal education) (AOR = 4.4; 95%CI 2.0-9.8) were determinants for negative perception among clients on ART while for ART Naïve clients; HIV and T2DM/HTN co-morbidities (AOR = 2.0; 95%CI 1.2-4.6) was the main determinant for negative perception. CONCLUSION Considerable number of respondents had low level of knowledge (41.1%) regarding T2DM/HTN specifically on the risk factors, prevention strategies and their associated complications and negative perception (43.7%) towards healthy practices for mitigating risk behaviors of the diseases. There is need for promoting awareness of T2DM/HTN risk factors and complications by considering determinants of low knowledge and negative perception among PLHIV.

From policy to practice: exploring the implementation of antiretroviral therapy access and retention policies between 2013 and 2016 in six sub-Saharan African countries. BMC Health Serv Res 2017; 17:758. [PMID: 29162065 PMCID: PMC5698969 DOI: 10.1186/s12913-017-2678-1] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2017] [Accepted: 11/03/2017] [Indexed: 11/13/2022] Open
Abstract
Background Understanding the implementation of 2013 World Health Organization (WHO) consolidated guidelines on the use of antiretroviral drugs for treating and preventing HIV infection at the facility level provides important lessons for the roll-out of future HIV policies. Methods A national policy review was conducted in six sub-Saharan African countries to map the inclusion of the 2013 WHO HIV treatment recommendations. Twenty indicators of policy adoption were selected to measure ART access (n = 12) and retention (n = 8). Two sequential cross-sectional surveys were conducted in facilities between 2013/2015 (round 1) and 2015/2016 (round 2) from ten health and demographic surveillance sites in Kenya, Malawi, South Africa, Tanzania, Uganda and Zimbabwe. Using standardised questionnaires, facility managers were interviewed. Descriptive analyses were used to assess the change in the proportion of facilities that implemented these policy indicators between rounds. Results Although, expansion of ART access was explicitly stated in all countries’ policies, most lacked policies that enhanced retention. Overall, 145 facilities were included in both rounds. The proportion of facilities that initiated ART at CD4 counts of 500 or less cells/μL increased between round 1 and 2 from 12 to 68%, and facilities initiating patients on 2013 WHO recommended ART regimen increased from 42 to 87%. There were no changes in the proportion of facilities reporting stock-outs of first-line ART in the past year (18 to 11%) nor in the provision of three-month supply of ART (43 to 38%). None of the facilities provided community-based ART delivery. Conclusion The increase in ART initiation CD4 threshold in most countries, and substantial improvements made in the provision of WHO recommended first-line ART regimens demonstrates that rapid adoption of WHO recommendations is possible. However, improved logistics and resources and/or changes in policy are required to further minimise ART stock-outs and allow lay cadres to dispense ART in the community. Increased efforts are needed to offer longer durations between clinic visits, a strategy purported to improve retention. These changes will be important as countries move to implement the revised 2015 WHO guidelines to initiate all HIV positive people onto ART regardless of their immune status.

Abstract
BACKGROUND Antiretroviral (ARV) drug treatment benefits the treated individual and can prevent HIV transmission. We assessed ARV drug use in a community-randomized trial that evaluated the impact of behavioral interventions on HIV incidence. METHODS Samples were collected in a cross-sectional survey after a 3-year intervention period. ARV drug testing was performed using samples from HIV-infected adults at 4 study sites (Zimbabwe; Tanzania; KwaZulu-Natal and Soweto, South Africa; survey period 2009-2011) using an assay that detects 20 ARV drugs (6 nucleoside/nucleotide reverse transcriptase inhibitors, 3 nonnucleoside reverse transcriptase inhibitors, and 9 protease inhibitors; maraviroc; raltegravir). RESULTS ARV drugs were detected in 2011 (27.4%) of 7347 samples; 88.1% had 1 nonnucleoside reverse transcriptase inhibitors ± 1-2 nucleoside/nucleotide reverse transcriptase inhibitors. ARV drug detection was associated with sex (women>men), pregnancy, older age (>24 years), and study site (P < 0.0001 for all 4 variables). ARV drugs were also more frequently detected in adults who were widowed (P = 0.006) or unemployed (P = 0.02). ARV drug use was more frequent in intervention versus control communities early in the survey (P = 0.01), with a significant increase in control (P = 0.004) but not in intervention communities during the survey period. In KwaZulu-Natal, a 1% increase in ARV drug use was associated with a 0.14% absolute decrease in HIV incidence (P = 0.018). CONCLUSIONS This study used an objective, biomedical approach to assess ARV drug use on a population level. This analysis identified factors associated with ARV drug use and provided information on ARV drug use over time. ARV drug use was associated with lower HIV incidence at 1 study site.

Abstract
Background Strong health laboratory systems and networks capable of providing high quality services are critical components of the health system and play a key role in routine diagnosis, care, treatment and disease surveillance. This study aimed to assess the readiness of the national health laboratory system (NHLS) and its capacity to support care and treatment of HIV/AIDS in Tanzania. Methods A documentary review was performed to assess the structure of the health system with reference to the status and capacity of the NHLS to support HIV diagnosis. Key informant interviews were also held with laboratory staff in all levels of the health care delivery system in four regions with different levels of HIV prevalence. Information sought included availability and utilization of laboratory guidelines, quality and the capacity of laboratories for diagnosis of HIV. Results The findings indicate that a well-established NHLS was in place. However, the coordination of HIV laboratory services was found to be weak. Forty six respondents were interviewed. In most laboratories, guidelines for HIV diagnosis were available but health care providers were not aware of their availability. Utilization of the guidelines for HIV diagnosis was higher at national level than at the lower levels. The low level of awareness and utilization of guidelines was associated with inadequate training and supervision. There was a shortage of human resource, mostly affecting the primary health care level of the system and this was associated with inequity in employment and training opportunities. Laboratories in public health facilities were better staffed and had more qualified personnel than private-owned laboratories. Conclusion Tanzania has a well established national health laboratory network sufficient to support HIV care and treatment services. However, laboratories at the primary health care level are constrained by inadequate resources and operate within a limited capacity. Improving the laboratory capacity in terms of number of qualified personnel, staff training on the national guidelines, laboratory diagnostic tools and coordination should be given a higher priority.

BMC Public Health 2015; 15:195. [PMID: 25884639 PMCID: PMC4349316 DOI: 10.1186/s12889-015-1460-8] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2014] [Accepted: 01/23/2015] [Indexed: 11/29/2022] Open
Abstract
Background The Tanzanian Government started scaling up its antiretroviral treatment (ART) program from referral, regional and district hospitals to primary health care facilities in October 2004. In 2010, most ART clinics were decentralized to primary health facilities. ART coverage, i.e. people living with HIV (PLHIV) on combination treatment as a proportion of those in need of treatment, provides the basis for evaluating the efficiency of ART programs at national and district level. We aimed to evaluate adult ART and pre-ART care coverage by age and sex at CD4 < 200, < 350 and all PLHIV in the Rufiji district of Tanzania from 2006 to 2010. Methods The numbers of people on ART and pre-ART care were obtained from routinely aggregated, patient-level, cohort data from care and treatment centers in the district. We used ALPHA model to predict the number in need of pre-ART care and ART by age and sex at CD4 < 200 and < 350. Results Adult ART coverage among PLHIV increased from 2.9% in 2006 to 17.6% in 2010. In 2010, coverage was 20% for women and 14.8% for men. ART coverage was 30.2% and 38.7% in 2010 with reference to CD4 criteria of 350 and 200 respectively. In 2010, ART coverage was 0 and 3.4% among young people aged 15–19 and 20–24 respectively. ART coverage among females aged 35–39 and 40–44 was 30.6 and 35% respectively in 2010. Adult pre-ART care coverage for PLHIV of CD4 < 350 increased from 5% in 2006 to 37.7% in 2010. The age-sex coverage patterns for pre-ART care were similar to ART coverage for both CD4 of 200 and 350 over the study period. Conclusions ART coverage in the Rufiji district is unevenly distributed and far from the universal coverage target of 80%, in particular among young men. The findings in 2010 are close to the most recent estimates of ART coverage in 2013. To strive for universal coverage, both the recruitment of new eligible individuals to pre-ART and ART and the successful retention of those already on ART in the program need to be prioritized.

Abstract
Background HIV and Non communicable diseases (NCDs) are major problem of public health importance in developing countries. This study was conducted to explore and establish information on the magnitude, distribution of NCDs risk factors among people living with HIV (PLWHIV) which is scarce in Tanzania. Method A cross sectional study was conducted to PLWHIV from 12 care and treatment clinics in Dar es Salaam and Mbeya regions from October 2011 to February 2012. Data on demographic characteristics, NCD risk factors including behavioral, biochemical tests and physical measurements was collected from PLWHIV. Results Of 754 PLWHIV recruited, 671(89.0%) consented to participate in the study and 354/671(52.8%) were on antiretroviral therapy (ART). The following NCD risk factors: raised blood levels of low density lipoprotein (61.3% vs 38.7%, p < 0.001) total cholesterol (TC) (71.6% vs 28.4%, p < 0.001) and triglyceride (67.0% vs 33.0%, p = 0.001) as well as overweight/obesity (61.1% vs 38.9%, p = 0.010), abnormal waist circumference (61.7% vs 38.3%, p < 0.001) and being aged >40 years (63.3% vs 36.7%, p < 0.001) were more prevalent among PLWHIV on ART than ART naïve. The prevalence of Diabetes mellitus among PLWHIV was 4.2% and was slightly high among those ART naïve (4.7% vs 3.7%). The prevalence of hypertension was 26.2% and was high among those on ART (30.0% vs 21.9%, p = 0.010). Being aged >40 years (AOR = 2.52, 95% CI 1.37-4.63), abnormal waist circumference (AOR = 2.37 95% CI 1.13-5.00), overweight/obesity (AOR = 2.71, 95% CI 1.26-5.84) and male sex (AOR = 1.17, 1.02-4.20) were the predictors of hypertension among patients on ART while raised TC (AOR = 1.47 (1.01-2.21) and being aged >40 years (AOR = 3.42, 95% CI 2.06-5.70) were predictors for hypertension among ART naïve patients. Conclusion This study has revealed that the magnitude of NCD risk factors is significantly higher among PLWHIV on ART than those not on ART. Initiating and strengthening of interventions for minimizing preventable NCD risks should be considered when initiating ART among PLWHIV. Regular monitoring of NCD risk factors is of paramount importance among ART patients.

Low risk of attrition among adults on antiretroviral therapy in the Rwandan national program: a retrospective cohort analysis of 6, 12, and 18 month outcomes. BMC Public Health 2014; 14:889. [PMID: 25168699 PMCID: PMC4161887 DOI: 10.1186/1471-2458-14-889] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2014] [Accepted: 07/29/2014] [Indexed: 12/01/2022] Open
Abstract
Background We report levels and determinants of attrition in Rwanda, one of the few African countries with universal ART access. Methods We analyzed data abstracted from health facility records of a nationally representative sample of adults [≥18 years] who initiated ART 6, 12, and 18 months prior to data collection; and collected facility characteristics with a health facility assessment questionnaire. Weighted proportions and rates of attrition [loss to follow-up or death] were calculated, and patient- and health facility-level factors associated with attrition examined using Cox proportional hazard models. Results 1678 adults initiated ART 6, 12 and 18 months prior to data collection, with 1508 person-years [PY] on ART. Attrition was 6.8% [95% confidence interval [CI] 6.0-7.8]: 2.9% [2.4-3.5] recorded deaths and 3.9% [3.4-4.5] lost to follow-up. Population attrition rate was 7.5/100PY [6.1-9.3]. Adjusted hazard ratio [aHR] for attrition was 4.2 [3.0-5.7] among adults enrolled from in-patient wards [vs 2.2 [1.6-3.0] from PMTCT, ref: VCT]. Compared to adults who initiated ART 18 months earlier, aHR for adults who initiated ART 12 and 6 months earlier was 1.8 [1.3-2.5] and 1.3 [0.9-1.9] respectively. Male aHR was 1.4 [1.0-1.8]. AHR of adults enrolled at urban health facilities was 1.4 [1.1-1.8, ref: rural health facilities]. AHR for adults with CD4+ ≥200 cells/μL vs <200 cells/μL was 0.8 [0.6-1.0]; and adults attending facilities with performance-based financing since 2004–2006 [vs. 2007–2008] had aHR 0.8 [0.6-0.9]. Conclusions Attrition was low in the Rwandan national program. The above patient and facility correlates of attrition can be the focus of interventions to sustain high retention.

Abstract
Background Prior to the scale-up of antiretroviral therapy (ART), demographic surveillance cohort studies showed higher mortality among migrants than residents in many rural areas. Objectives This study quantifies the overall and AIDS-specific mortality between migrants and residents prior to ART, during ART scale-up, and after widespread availability of ART in Rufiji district in Tanzania. Design In Health and Demographic Surveillance System (HDSS), the follow-up of individuals aged 15–59 years was categorized into three periods: before ART (1998–2003), during ART scale-up (2004–2007), and after widespread availability of ART (2008–2011). Residents were those who never migrated within and beyond HDSS, internal migrants were those who moved within the HDSS, and external migrants were those who moved into the HDSS from outside. Mortality rates were estimated from deaths and person-years of observations calculated in each time period. Hazard ratios were estimated to compare mortality between migrants and residents. AIDS deaths were identified from verbal autopsy, and the odds ratio of dying from AIDS between migrants and residents was estimated using the multivariate logistic regression model. Results Internal and external migrants experienced higher overall mortality than residents before the introduction of ART. After widespread availability of ART overall mortality were similar for internal and external migrants. These overall mortality experiences observed were similar for males and females. In the multivariate logistic regression model, adjusting for age, sex, education, and social economic status, internal migrants had similar likelihood of dying from AIDS as residents (adjusted odds ratio [AOR]=1.14, 95% confidence interval [CI]: 0.70–1.87) while external migrants were 70% more likely to die from AIDS compared to residents prior to the introduction of ART (AOR=1.70, 95% CI: 1.06–2.73). After widespread availability of ART with the same adjustment factors, the odds of dying from AIDS were similar for internal migrants and residents (AOR=1.56, 95% CI: 0.80–3.04) and external migrants and residents (AOR=1.42, 95% CI: 0.76–2.66). Conclusions Availability of ART has reduced the number of HIV-infected migrants who would otherwise return home to die. This has reduced the burden on rural communities who had cared for the return external migrants.

Mori AT, Owenya J. Stock-outs of antiretroviral drugs and coping strategies used to prevent changes in treatment regimens in Kinondoni District, Tanzania: a cross-sectional study. J Pharm Policy Pract 2014; 7:3. [PMID: 25848543 PMCID: PMC4366935 DOI: 10.1186/2052-3211-7-3] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2013] [Accepted: 04/15/2014] [Indexed: 11/27/2022] Open
Abstract
Objectives Since 2004, the government of Tanzania has been rolling out antiretroviral treatment programs all over the country. However, the capacity of the health system to cope with the rapid scale-up of these programs is a major concern, and problems may result in drug stock-outs that force changes in treatment regimens. This study aims to explore stock-outs of antiretroviral drugs and further determine the coping strategies employed to prevent changes in treatment regimens in HIV/AIDS care and treatment clinics in Kinondoni District, Dar es Salaam, Tanzania. Methods A cross-sectional study was conducted in 20 HIV/AIDS care and treatment clinics. Interviews were conducted with the person in charge and a member of the pharmacy staff from each clinic using a pre-tested semi-structured interview guide. Verbal responses were transcribed, coded and analysed by thematic approach. Quantitative data were analysed using Excel spreadsheet (Microsoft Excel®, Microsoft Corporation). Results The total number of clients enrolled in the visited clinics was 32,147, of whom 20,831 (64.8%) had already been initiated onto antiretroviral therapies (ART). Stock-out of antiretroviral drugs was reported in 16 out of the 20 clinics, causing 210 patients to change their ART regimens, during the 12 months preceding the survey. Inefficient supply systems, quantification problems and short expiry duration were cited as the main causes of stock-outs. The coping strategies utilised to prevent changes in ART regimens were: shortening of the refill period, borrowing and moving patients to other clinics. Conclusion Changes in ART regimens due to stock-outs of antiretroviral drugs occurred in a small but significant number of patients. This increases the risk of the emergence of drug-resistant HIV strains. Healthcare workers use various coping strategies to prevent changes in ART regimens but, unfortunately, some of these strategies are likely to increase patient-borne costs, which may discourage them from attending their routine clinics, hence leading to unplanned treatment interruptions.

Abstract
Better quality of services is essential for the sustainability of HIV programs, in particular in rural Sub-Saharan Africa, to support the increasing number of individuals treated with combination antiretroviral therapy (cART). However, longitudinal data from rural care and treatment centers (CTC) are scarce. The objective was to assess trend in quality of care for HIV infected persons before start of combination antiretroviral therapy (pre-ART). A retrospective analysis of pre-ART registers and patient's files of 1950 patients enrolled in the Bagamoyo CTC in Tanzania between 2008 and 2010 analyzing was conducted; with parameters including year of enrollment, gender, age, CD4 cell count and WHO clinical stage at time enrollment. We noted a significant increase by 20% of total patients who had CD4 cell count performed from 69% (n=457) in 2008, 83% (n=493) 2009 to 89% (n=616) 2010 (X2= 87.014, P2= 14.945, P2= 85.028, P3. Efforts must be undertaken for more HIV testing and timely referral of HIV-infected patients to CTC.

Abstract
BACKGROUND To evaluate the on-going scale-up of HIV programs, we assessed trends in patient characteristics at enrolment and ART initiation over 7 years of implementation. METHODS Data were from Optimal Models, a prospective open cohort study of HIV-infected (HIV+) adults (≥15 years) and children (<15 years) enrolled from January 2005 to December 2011 at 44 HIV clinics in 3 regions of mainland Tanzania (Kagera, Kigoma, Pwani) and Zanzibar. Comparative statistics for trends in characteristics of patients enrolled in 2005-2007, 2008-2009 and 2010-2011 were examined. RESULTS Overall 62,801 HIV + patients were enrolled: 58,102(92.5%) adults, (66.5% female); 4,699(7.5%) children.Among adults, pregnant women enrolment increased: 6.8%, 2005-2007; 12.1%, 2008-2009; 17.2%, 2010-2011; as did entry into care from prevention of mother-to-child HIV transmission (PMTCT) programs: 6.6%, 2005-2007; 9.5%, 2008-2009; 12.6%, 2010-2011. WHO stage IV at enrolment declined: 27.1%, 2005-2007; 20.2%, 2008-2009; 11.1% 2010-2011. Of the 42.5% and 29.5% with CD4+ data at enrolment and ART initiation respectively, median CD4+ count increased: 210 cells/μL, 2005-2007; 262 cells/μL, 2008-2009; 266 cells/μL 2010-2011; but median CD4+ at ART initiation did not change (148 cells/μL overall). Stavudine initiation declined: 84.9%, 2005-2007; 43.1%, 2008-2009; 19.7%, 2010-2011.Among children, median age (years) at enrolment decreased from 6.1(IQR:2.7-10.0) in 2005-2007 to 4.8(IQR:1.9-8.6) in 2008-2009, and 4.1(IQR:1.5-8.1) in 2010-2011 and children <24 months increased from 18.5% to 26.1% and 31.5% respectively. Entry from PMTCT was 7.0%, 2005-2007; 10.7%, 2008-2009; 15.0%, 2010-2011. WHO stage IV at enrolment declined from 22.9%, 2005-2007, to 18.3%, 2008-2009 to 13.9%, 2010-2011. Proportion initiating stavudine was 39.8% 2005-2007; 39.5%, 2008-2009; 26.1%, 2010-2011. Median age at ART initiation also declined significantly. CONCLUSIONS Over time, the proportion of pregnant women and of adults and children enrolled from PMTCT programs increased. There was a decline in adults and children with advanced HIV disease at enrolment and initiation of stavudine. Pediatric age at enrolment and ART initiation declined. Results suggest HIV program maturation from an emergency response.

Abstract
Background Generalizable data are needed on the magnitude and determinants of adherence and virological suppression among patients on antiretroviral therapy (ART) in Africa. Methods We conducted a cross-sectional survey with chart abstraction, patient interviews and site assessments in a nationally representative sample of adults on ART for 6, 12 and 18 months at 20 sites in Rwanda. Adherence was assessed using 3- and 30-day patient recall. A systematically selected sub-sample had viral load (VL) measurements. Multivariable logistic regression examined predictors of non-perfect (<100%) 30-day adherence and detectable VL (>40 copies/ml). Results Overall, 1,417 adults were interviewed and 837 had VL measures. Ninety-four percent and 78% reported perfect adherence for the last 3 and 30 days, respectively. Eighty-three percent had undetectable VL. In adjusted models, characteristics independently associated with higher odds of non-perfect 30-day adherence were: being on ART for 18 months (vs. 6 months); younger age; reporting severe (vs. no or few) side effects in the prior 30 days; having no documentation of CD4 cell count at ART initiation (vs. having a CD4 cell count of <200 cells/µL); alcohol use; and attending sites which initiated ART services in 2003–2004 and 2005 (vs. 2006–2007); sites with ≥600 (vs. <600 patients) on ART; or sites with peer educators. Participation in an association for people living with HIV/AIDS; and receiving care at sites which regularly conduct home-visits were independently associated with lower odds of non-adherence. Higher odds of having a detectable VL were observed among patients at sites with peer educators. Being female; participating in an association for PLWHA; and using a reminder tool were independently associated with lower odds of having detectable VL. Conclusions High levels of adherence and viral suppression were observed in the Rwandan national ART program, and associated with potentially modifiable factors.

Abstract
OBJECTIVES To analyse mortality, loss to follow-up (LTFU) and retention on antiretroviral treatment (ART) in the first year of ART across all age groups in the Malawi national ART programme. DESIGN Cohort study including all patients who started ART in Malawi's public sector clinics between 2004 and 2007. METHODS ART registers were photographed, information entered into a database and merged with data from clinics with electronic records. Rates per 100 patient-years and cumulative incidence of retention were calculated. Subhazard ratios (sHRs) of outcomes adjusted for patient and clinic-level characteristics were calculated in multivariable analysis, applying competing risk models. RESULTS A total of 117,945 patients contributed 85,246 person-years: 1.0% were infants below 2 years, 7.4% children 2-14, 7.5% young people 15-24, and 84.2% adults 25 years and above. Sixty percent of patients were female: women outnumbered men from age 14 to 35 years. Mortality and LTFU were higher in men from age 20 years. Infants and young people had the highest rates per 100 person-years for mortality (23.0 and 19.4) and LTFU (24.7 and 19.3), and the highest adjusted relative risks compared to age group 25-34 years: sHRs were 1.37 [95% confidence interval (CI) 1.17-1.60] and 1.17 (95% CI 1.10-1.25) for death and 1.37 (95% CI 1.18-1.59) and 1.27 (95% CI 1.19-1.35) for LTFU, respectively. CONCLUSION In this country-wide study patients aged 0-1 and 15-24 years had the highest risk of death and LTFU, and from age 20 men were at higher risk than women. Interventions to improve outcomes in these patient groups are required.

Abstract
OBJECTIVE To explore attitudes, perceptions and practices among health care workers, antiretroviral treatment (ART) patients and community members regarding ART care and the social consequences of ART roll-out in rural Tanzania. METHODS We performed focus group discussions and in-depth interviews with health care workers, community members, ART patients, religious leaders, as well as social workers. Field observations and ethnographic assessments were conducted in parallel. RESULTS We found widespread negative attitudes and perceptions of ART care HIV testing and the ART programme, a lack of trust in its sustainability, as well as lack of community and health worker involvement in the programme planning and treatment. HIV-positive individuals on ART reported risky behaviours with the aim of revenge and were feared by community members. We also found that the ART availability was seen as an incentive to engage in HIV testing among some community members. CONCLUSION Our findings underline the importance of involving health workers and the community at a high level and their important role in promoting trust in the ART programme. There is an immense need to adjust interventions focusing on stigma reduction in the direction of ART scale-up and to build awareness among ART patients so they understand how risky behaviours affect their personal well-being and the community at large.
