Tenofovir stock shortages have limited impact on clinic- and patient-level HIV treatment outcomes in public sector clinics in South Africa.

OBJECTIVE: Using data from four public sector clinics in South Africa, we sought to investigate provider- and patient-level outcomes, to understand how the 2012 tenofovir stock shortage affected the HIV care and monitoring of ART patients. METHODS: Prospective cohort analysis of ART-naïve, non-pregnant, HIV-infected patients >18 years initiating first-line ART between 1 July 2011-31 March 2013. Linear regression was used for all outcomes (number of ART initiates, days between pharmacy visits, transfers, single-drug substitutions, treatment interruptions, missed pharmacy visits, loss to follow-up and elevated viral load). We fit splines to smooth curves with knots at the beginning (1 February 2012) and end (31 August 2012) of the stock shortage and displayed results graphically by clinic. Difference-in-difference models were used to evaluate the effect of the stock shortage on outcomes. RESULTS: Results suggest a potential shift in the management of patients during the shortage, mainly fewer average days between visits during the shortage vs. before or after at all four clinics, and a significant difference in the proportion of patients missing visits during vs. before (RD: 1.2%; 95% CI: 0.5%, 2.0%). No significant difference was seen in other outcomes. CONCLUSION: While South Africa has made great strides to extend access to ART and increase the quality of the health services provided, patient care can be affected when stock shortages/outs occur. While our results show little effect on treatment outcomes, this most likely reflects the clinics' ability to mitigate the crisis by continuing to keep patient care and treatment as consistent as possible.

Challenges encountered in providing integrated HIV, antenatal and postnatal care services: a case study of Katakwi and Mubende districts in Uganda.

BACKGROUND: Integration of sexual and reproductive health (SRH), HIV/AIDS and maternal health (MH) services is a critical strategy to confront the HIV/AIDS epidemic, high maternal mortality and the unmet need for contraception. In 2011 the AIDS Information Centre (AIC) in partnership with the Ministry of Health implemented SRH, HIV/AIDS and MH integration services in the districts of Katakwi and Mubende in Uganda. This paper documents challenges encountered in providing these integrated services in the two districts. METHODS: This was a cross-sectional qualitative study conducted in Mubende and Katakwi districts in Uganda. Data were collected using 10 focus group discussions with 89 women attending ANC and postnatal care and 21 key informant interviews with district managers and health workers who were involved in the integrated service delivery. Content thematic approach was used for data analysis. RESULTS: The study findings indicate that various challenges were encountered in integrating HIV, ANC and PNC services. Major challenges included inadequate staff, gaps in knowledge of service providers especially with regard to provision of long-term family planning, limited space, shortage of critical supplies such as HIV test kits, drugs and gloves. CONCLUSION: These findings indicate that the delivery of integrated HIV, SRH and MH services is hampered greatly by health system challenges and depict the need for additional staffing in health facilities, capacity building of health workers and health managers as well as ensuring sufficient supplies to health facilities for smooth implementation of integrated SRH, HIV and MH services.

[The role of supply-side characteristics of services in AIDS mortality in Mexico]. / Exploración del rol de la oferta de servicios para explicar la variación de la mortalidad por sida en México.

OBJECTIVE: To document the association between supply-side determinants and AIDS mortality in Mexico between 2008 and 2013. MATERIALS AND METHODS: We analyzed the SALVAR database (system for antiretroviral management, logistics and surveillance) as well as data collected through a nationally representative survey in health facilities. We used multivariate logit regression models to estimate the association between supply-side characteristics, namely management, training and experience of health care providers, and AIDS mortality, distinguishing early and non-early mortality and controlling for clinical indicators of the patients. RESULTS: Clinic status of the patients (initial CD4 and viral load) explain 44.4% of the variability of early mortality across clinics and 13.8% of the variability in non-early mortality. Supply-side characteristics increase explanatory power of the models by 16% in the case of early mortality, and 96% in the case of non-early mortality. CONCLUSIONS: Aspects of management and implementation of services contribute significantly to explain AIDS mortality in Mexico. Improving these aspects of the national program, can similarly improve its results.

Exploración del rol de la oferta de servicios para explicar la variación de la mortalidad por sida en México / The role of supply-side characteristics of services in AIDS mortality in Mexico

Objetivo. Documentar la asociación entre factores de la oferta de servicios de atención de VIH sobre la mortalidad por sida en México en el periodo 2008-2013. Material y métodos. Se analizaron datos del sistema de administración, logística y vigilancia de antirretrovirales (SALVAR) y de una encuesta aplicada en unidades de atención. Se utilizaron modelos de regresión logit multivariados para estimar la asociación entre características de la oferta de servicios -en particular, de la gerencia de servicios y de la capacitación y experiencia de los prestadores- y la mortalidad por sida, distinguiendo entre mortalidad temprana y no temprana, y controlando por características clínicas de los pacientes. Resultados. Las características clínicas de los pacientes (CD4 inicial y carga viral) explican 44.4% de la variabilidad en la mortalidad temprana entre clínicas y 13.8% de la variabilidad de mortalidad no temprana. Las características de la oferta aumentan 16% del poder explicativo en el caso de la mortalidad temprana y 96% en el de la mortalidad no temprana. Conclusiones. Los aspectos de gerencia e implementación de los servicios de atención de VIH contribuyen significativamente a explicar la mortalidad por sida en México. Mejorar estos aspectos del programa nacional puede mejorar sus resultados.

Antiretroviral therapy program expansion in Zambézia Province, Mozambique: geospatial mapping of community-based and health facility data for integrated health planning.

OBJECTIVE: To generate maps reflecting the intersection of community-based Voluntary Counseling and Testing (VCT) delivery points with facility-based HIV program demographic information collected at the district level in three districts (Ile, Maganja da Costa and Chinde) of Zambézia Province, Mozambique; in order to guide planning decisions about antiretroviral therapy (ART) program expansion. METHODS: Program information was harvested from two separate open source databases maintained for community-based VCT and facility-based HIV care and treatment monitoring from October 2011 to September 2012. Maps were created using ArcGIS 10.1. Travel distance by foot within a 10 km radius is generally considered a tolerable distance in Mozambique for purposes of adherence and retention planning. RESULTS: Community-based VCT activities in each of three districts were clustered within geographic proximity to clinics providing ART, within communities with easier transportation access, and/or near the homes of VCT volunteers. Community HIV testing results yielded HIV seropositivity rates in some regions that were incongruent with the Ministry of Health's estimates for the entire district (2-13% vs. 2% in Ile, 2-54% vs. 11.5% in Maganja da Costa, and 23-43% vs. 14.4% in Chinde). All 3 districts revealed gaps in regional disbursement of community-based VCT activities as well as access to clinics offering ART. CONCLUSIONS: Use of geospatial mapping in the context of program planning and monitoring allowed for characterizing the location and size of each district's HIV population. In extremely resource limited and logistically challenging settings, maps are valuable tools for informing evidence-based decisions in planning program expansion, including ART.

Lost-to-care and engaged-in-care HIV patients in Leningrad Oblast, Russian Federation: barriers and facilitators to medical visit retention.

Sixty-nine percent of the 1.5 million Eastern Europeans and Central Asians with HIV live in the Russian Federation. Antiretroviral therapy (ART) is effective but cannot help those who leave treatment. Focus groups with patients who dropped out of ART for ≥12 months (lost-to-care, LTCs, n = 21) or continued for ≥12 months (engaged-in-care; EICs; n = 24) were conducted in St. Petersburg. Structural barriers included stigma/discrimination and problems with providers and accessing treatment. Individual barriers included employment and caring for dependents, inaccurate beliefs about ART (LTC only), side-effects, substance use (LTCs, present; EICs, past), and depression. Desire to live, social support, and spirituality were facilitators for both; EICs also identified positive thinking and experiences with ART and healthcare/professionals. Interventions to facilitate retention and adherence are discussed.

[Cryptococcal neuromeningitidis in HIV-infected patients in Bangui, in the era of antiretroviral treatment]. / La cryptococcose neuroméningée au cours de l'infection à VIH à Bangui, à l'ère du traitement antirétroviral.

The cryptococcal neuromeningitis is the most common fungal meningitis infections in the course of HIV/AIDS. This is the number two of opportunist infection of the central nervous system. The authors post the outcomes of a retrospective study conducted related to 122 cases of cryptococcal neuromeningitis observed over for four years ago, in Bangui in the Central African Republic, this at time when antiretroviral treatment has been avaible, corresponding to a prevalence of 6.5%. These infections very aften occur more in female folk, and to patients whose average age is 35 years old, ranging from 18 to 69 years old. The clinical symptoms often found had been headache (98,3.%), fever (95.0%), the impairing of the overall condition of the patient (86.7%) and neck stiffness (85.9%). It makes sense to notice that comorbidity case alowgwith tuberculosis, intestinal candidiasis, bacterial pneumonia and Kaposi's diseases were found out. The screening of the cerebrospinal fluid showed a sound cell count and even low count in 12.2% of cases. Direct examination of cerebrospinal fluid with India ink helps in diagnosis of 97.5% of cases, and the culture carried out from 74 patients was in any case positive. This culture allowed the diagnosis of three patients whose examination along side with India ink has been negative. The CD4 cell count was less than 100/mm(3) in 97.7% of cases. The rate of the fatality cases has been 66.4%, it has been badly impacted by a CD4 count <50/mm(3) and the lack of antiretroviral therapy. Despite the establishment of a national antiretroviral treatment program to do influence the frequency of opportunistic infections whose cryptococcal neuromeningitis, this condition is still present although it is declining. The clinical variability of this disease requires early diagnosis to avoid delayed treatment corollary of a very high mortality as we have observed.

Learning from HIV: exploring migration and health in South Africa.

Southern Africa is associated with high HIV prevalence and diverse population movements, including temporary, circular movements between rural and urban areas within countries (internal migration), and movements across borders (international migration). Whilst most migration in southern Africa is associated with the search for improved livelihood opportunities in urban areas a small--but significant--number of people are forced to migrate to escape persecution or civil war. This paper utilises recent empirical studies conducted in South Africa to explore linkages between migration into urban areas and health, focusing on HIV. It is shown that the relationship between migration and HIV is complex; that both internal and international migrants move to urban areas for reasons other than healthcare seeking; and that most migratory movements into urban areas involve the positive selection of healthy individuals. Whilst healthy migration has economic benefits for rural sending households, the data uncovers an important process of return migration (internally or across borders) in times of sickness, with the burden of care placed on the rural, sending household. There is an urgent need for a comprehensive response that maintains the health of migrants in urban areas, and provides support to rural areas in times of sickness.

Pilot assessment of supply chains for pharmaceuticals and medical commodities for malaria, tuberculosis and HIV infection in Ethiopia.

To obtain preliminary data on the drug supply management system in Ethiopia, selected facilities were assessed for the availability of essential drugs and commodities for malaria, TB and HIV. Of the 48 surveyed hospitals and health centers, 9 (19%), 9 (19%) and 10 (21%) did not have malaria, TB or HIV drugs, respectively. Similarly, of 27 health posts, 9 (33%) and 6 (22%) did not have rapid diagnostic tests and antimalarial drugs, respectively. The findings indicated an inadequate availability of essential drugs and commodities in the surveyed facilities as well as weaknesses in human resources and training. Assessments of commodity supply chains to ensure operational program success and impact are important.

Lack of pre-antiretroviral care and competition from traditional healers, crucial risk factors for very late initiation of antiretroviral therapy for HIV--a case-control study from eastern Uganda.

BACKGROUND: Although WHO recommends starting antiretroviral treatment at a CD4 count of 350 cells/[µ]L, many Ugandan districts still struggle with large proportions of clients initiating ART very late at CD4<50 cells/[µ]L. This study seeks to establish crucial risk factors for very late ART initiation in eastern Uganda. METHODS: All adult HIV-infected clients on ART in Iganga who enrolled between 2005 and 2009 were eligible for this case-control study. Clients who started ART at CD4 cell count of <50 cells/[µ]L (very late initiators) were classified as cases and 50-200 cells/[µ]L (late initiators) as control subjects. A total of 152 cases and 202 controls were interviewed. Multivariate analyses were performed to calculate adjusted odds ratios and 95% confidence intervals. RESULTS: Reported health system-related factors associated with very late ART initiation were stock-outs of antiretroviral drugs stock-outs (affecting 70% of the cases and none of the controls), competition from traditional/spiritual healers (AOR 7.8, 95 CI% 3.7-16.4), and lack of pre-ARV care (AOR 4.6, 95% CI: 2.3-9.3). Men were 60% more likely and subsistence farmers six times more likely (AOR 6.3, 95% CI: 3.1-13.0) to initiate ART very late. Lack of family support tripled the risk of initiating ART very late (AOR 3.3, 95% CI: 1.6-6.6). CONCLUSION: Policy makers should prevent ARV stock-outs though effective ARV procurement and supply chain management. New HIV clients should seek pre-ARV care for routine monitoring and determination of ART eligibility. ART services should be more affordable, accessible and user-friendly to make them more attractive than traditional healers.

User satisfaction with pharmacy services in the Brazilian National STD/AIDS Program: validity and reliability issues.

The objective of this study is to evaluate the psychometric properties of a user satisfaction scale regarding the Brazilian National STD/AIDS Program, specifically related to dispensing AIDS medicines. The scale was developed and applied in a study covering 10 Brazilian States that evaluated the quality of medicine dispensing. The questionnaire was answered by 1,412 people living with HIV and undergoing antiretroviral therapy. Construct validation involved two stages of factor analysis. The item-total correlation matrix was analyzed, and tests for associations between the target variable, socio-demographic variables, and related constructs were performed. Reliability was studied by means of the sub-scales' internal consistency, estimated by Cronbach's alpha. Five relevant satisfaction dimensions were identified. A moderate level of internal consistency was found for these dimensions, suggesting they were adequate. The results of the association tests agreed with other studies reported in the literature. We conclude that the instrument is appropriate for application in similar populations with adequate psychometric characteristics and serves to measure users' assessments of the pharmaceutical services received and helps to orient improvements in such services.

O objetivo do presente artigo é avaliar propriedades psicométricas de uma escala de satisfação de usuários do Programa Nacional de DST/AIDS com a dispensação de medicamentos. A escala foi desenvolvida e aplicada num estudo abrangendo dez estados brasileiros para avaliar a qualidade da dispensação de medicamentos. O questionário foi respondido por 1.412 pessoas vivendo com HIV em tratamento com anti-retrovirais. Para validação de constructo, foram realizadas duas etapas de análise fatorial. A matriz de correlação item-escala corrigida foi analisada; testes de associação entre a variável de interesse, variáveis sócio-demográficas e constructos relacionados foram realizados. A confiabilidade foi estudada por meio da consistência interna das subescalas, estimada pelo alpha de Cronbach. Cinco dimensões da satisfação foram identificadas. Encontrou-se consistência interna moderada para essas dimensões, sugerindo adequações. Houve concordância entre os resultados dos testes de associação realizados e os achados de outros estudos descritos na literatura. O instrumento mostrou-se apropriado para ser aplicado em populações semelhantes, servindo para aferir a avaliação dos usuários sobre os serviços recebidos e assim orientar melhorias nos serviços avaliados.

Conceptualizing the integration of HIV treatment and prevention: findings from a process evaluation of a community-based, national capacity-building intervention.

OBJECTIVE: This paper responds to a gap in knowledge about the conceptualization of integration in community-based AIDS organizations (CBAOs). METHODS: A community-based process evaluation was conducted of a national intervention, developed by the Canadian AIDS Treatment Information Exchange (CATIE), to enhance treatment information provision in CBAOs and encourage its integration with prevention services. Our study involved 13 interviews with intervention participants in 6 CBAOs across Canada, CATIE staff, and funders, as well as a 25-person verification exercise. RESULTS: Intervention participants conceptualized integration as linking front-line HIV treatment, health promotion and prevention services, emphasizing mediation between scientific and lay knowledge, the political context of integration and the role of social determinants in clients' health and access to services. Challenges to integration include high staff turnover and inflexible funding structures. Complex health education related to the relationship between viral load and HIV transmission is a critical area of integrated service delivery. CONCLUSION: Study findings help distinguish a community-based concept of HIV-related integration from alternative uses of the term while pointing out key tensions associated with efforts to integrate HIV prevention and treatment in a community-based context.

Home deliveries: implications for adherence to nevirapine in a PMTCT programme in rural Malawi.

Although nevirapine (NVP) is provided by prevention of mother-to-child-transmission (PMTCT) of HIV programmes to be taken at onset of labor independent of place of delivery, few studies have assessed adherence to NVP outside the hospital setting. This study aimed to follow women in a PMTCT programme up to delivery and to assess the adherence to the prophylaxis in rural Malawi. A total of 75 HIV-positive women were registered in the PMTCT at Malamulo SDA hospital between January and June 2005. Forty women (53%) delivered in the hospital and 35 (47%) did not. Of the 35 women who delivered at home, it was possible to trace 27 (77.2%). All women who delivered in the hospital took their NVP tablets and all their babies had NVP syrup except one baby who died soon after delivery. Of the 27 traced women who had not delivered in the hospital, 16 (59.3%) had access to NVP and had taken their tablets during labor. However, none of their babies was taken back to the health facility for NVP syrup. Traditional birth attendants might be crucial in efforts aiming to increase adherence to NVP among women and their babies.

The influence of antiretroviral therapy on the uptake of HIV testing in Tutume, Botswana.

This paper describes how the national antiretroviral (ARV) programme in Botswana has influenced the willingness of the community of Tutume District, Botswana to come forward for HIV testing. A retrospective review of Tutume Primary Hospital records was performed for three different periods: prior to the national antiretroviral therapy (ART) programme, once ART was available in limited centres and once ART was available locally. There was a five-fold increase in the number of HIV tests performed once treatment became available locally, primarily due to female voluntary testing. Access to free ART increases the HIV testing rate of previously reluctant communities.

Antiretroviral therapy in public and private routine health care clinics in Cameroon: lessons from the Douala antiretroviral (DARVIR) initiative.

A review of the hospital charts for 788 patients treated in 19 public and private clinics in Cameroon showed that clinical follow-up visits, biologic follow-up visits, and drug supply were irregular and that many patients interrupted treatment. Virological and immunologic effectiveness of therapy was as expected in patients for whom results were available.

Access to antiretroviral treatment in Latin American countries and the Caribbean.

OBJECTIVES: To assess the access to antiretroviral therapy in the Latin America and Caribbean region and the main issues involved. METHODS: A review of National AIDS Programmes reports, published studies on HIV access to antiretroviral drugs, and personal communications from National AIDS Programmes in the region. RESULTS: Most countries have, or are in the process of developing, laws and regulations to ensure better access to antiretroviral drugs for people in need. However, there are still many countries that either have not implemented policies or do not have policies. There has been an important decrease in the cost of drugs, but prices are still too high for all countries to afford them. The benefits in decreased mortality and hospitalizations in the countries with high coverage are significant. The number of people receiving antiretroviral therapy has been estimated to be close to 170,000 individuals; however, this figure only represents a fraction of the people in need in the region. Some different strategies will have to be implemented in order to increase coverage. CONCLUSION: Renewed efforts are needed from both governments and international community organizations to strengthen the health services and increase access to antiretroviral drugs.

Use of complementary and alternative therapies in HIV-infected patients.

The use of complementary and alternative medicine (CAM) therapies is widespread in many chronic illnesses, including human immunodeficiency virus (HIV) infection. The objective of this study was to determine the impact of increasingly effective antiretroviral therapy on the use of CAM in an HIV-positive patient population. A written survey was given to 191 HIV-positive outpatients. Participation was voluntary and anonymous. One hundred twenty-eight patients (67%) used CAM at some time to control HIV and 76 (40%) of the patients were currently using CAM. The major forms of CAM used were exercise (43%), lifestyle changes (38%), dietary supplements (37%), counseling (27%), herbal medications (26%), megavitamins (24%), and prayer therapy (24%). One hundred forty-one patients (74%) used a protease inhibitor medication, 28 (15%) used a protease inhibitor sparing regime, and 22 (11%) had no current or prior antiretroviral use. Eighty-two (43%) patients indicated that their doctor knew they used CAM and 56 patients (29%) received their information about CAM from a doctor or other health care professional. Of 128 patients who used CAM, 90 (70%) felt CAM improved their quality of life. Income of $15,000 or more per year and discontinuation of medications by patients for any reason in the past were the best predicators of CAM use for patients in general and also those on protease inhibitor therapy. CD(4) count, educational status, year of HIV diagnosis, and martial status were not effective predictors of CAM use. Use of CAM remains widespread among patients with HIV infection even with the availability of effective, yet noncurative antiretroviral therapy and does not correlate with type of antiretroviral therapy used or clinical status.
