A qualitative study of the development and utilization of health facility-based immunization microplans in Uganda.

BACKGROUND: In 2006, Uganda adopted the Reaching Every District strategy with the goal of attaining at least 80% coverage for routine immunizations in every district. The development and utilization of health facility/district immunization microplans is the key to the strategy. A number of reports have shown suboptimal development and use of microplans in Uganda. This study explores factors associated with suboptimal development and use of microplans in two districts in Uganda to pinpoint challenges encountered during the microplanning process. METHODS: A qualitative study was conducted comparing two districts: Kapchorwa, with low immunization coverage, and Luwero with high immunization coverage. Data were collected through multilevel observation of health facilities, planning sessions and planning meetings; records review of microplans, micromaps and meeting minutes; 57 interviews with health workers at the ministry level and lower-level health facility workers. Data were analysed using NVivo 8 qualitative text analysis software. Transcripts were coded, and memos and display matrices were developed to examine the process of developing and utilizing microplans, including experiences of health workers (implementers). RESULTS: Three key findings emerged from this study. First, there are significant knowledge gaps with regard to the microplanning process among health workers at all levels (community and district health facility and nationally). Limited knowledge about communities and programme catchment areas greatly hinders the planning process by limiting the ability to identify hard-to-reach areas and to prioritize areas according to need. Secondly, the microplanning tool is bulky and complex. Finally, microplanning is being implemented in the context of already overtasked health personnel who have to conduct several other activities as part of their daily routines. CONCLUSIONS: In order to achieve quality improvement as outlined in the Reaching Every District campaign, the microplanning process should be revised. Health workers' misunderstanding and limited knowledge about the microplanning process, especially at peripheral health facilities, coupled with the complex, bulky nature of the microplanning tool, reduces the effectiveness of microplanning in improving routine immunization in Uganda. This study reveals the need to reduce the complexity of the tool and to identify ways to train and support workers in the use of the revised tool, including support in incorporating the microplanning process into their busy schedules.

Effectiveness of a mobile antiretroviral pharmacy and HIV care intervention on the continuum of HIV care in rural Uganda.

Adherence to antiretroviral therapy (ART) is critical in order to achieve viral suppression. We designed an intervention, Mobile Antiretroviral Therapy and HIV care (MAP-HC) in rural southwestern Uganda aimed to reduce travel distance and hypothesized that MAP-HC would improve ART adherence and rates of viral load suppression. The study was conducted at two district hospitals, among patients who lived >5 km from the hospital. For each hospital, we identified 4 health centers in the catchment area to serve as site for the mobile pharmacy. Each site was visited once a month to provide ART refills and adherence counseling. We measured patient waiting time, adherence and viral load suppression before and after the intervention. The proportion of patients who missed an ART dose in the last 30 days dropped from 20% to 8.5% at 12 months post-intervention (p = 0.009) and those with detectable viral load dropped from 19.9% to 7.4% (p = 0.001), however, mean waiting time increased from 4.48 to 4.76 h (p = 0.13). Mobile pharmacy intervention in rural Uganda is feasible and resulted in improvement in adherence and viral load suppression. Although it did not reduce patient waiting time at the clinic, we recommend scale-up in rural areas where patients face transportation challenges.

Routines, Hope, and Antiretroviral Treatment among Men and Women in Uganda.

Antiretroviral treatment programs, despite biomedical emphases, require social understanding and transformations to be successful. In this article, we draw from a qualitative study of HIV treatment seeking to examine the drug-taking routines and health-related subjectivities of men and women on antiretroviral treatment (ART) at two sites in Uganda. We show that while not all participants in ART programs understand clinical protocols in biomedical terms, they adopt treatment-taking strategies to integrate medication into daily practices and social spaces. In turn, these embedded practices and understandings shape long-term hopes and fears for living with HIV, including the possibility of a cure. More significant than new forms of citizenship or sociality, we suggest that quotidian dimensions of treatment normalization shape the long-term experience of medication and outlook for the future.

Experiences of medical device innovators as they navigate the regulatory system in Uganda.

Objective: A medical device must undergo rigorous regulatory processes to verify its safety and effectiveness while in use. In low-and middle-income countries like Uganda however, medical device innovators and designers face challenges around bringing a device from ideation to being market-ready. This is mainly attributed to a lack of clear regulatory procedures among other factors. In this paper, we illustrate the current landscape of investigational medical devices regulation in Uganda. Methods: Information about the different bodies involved in regulation of medical devices in Uganda was obtained online. Nine medical device teams whose devices have gone through the Ugandan regulatory system were interviewed to gain insights into their experiences with the regulatory system. Interviews focused on the challenges they faced, how they navigated them, and factors that supported their progress towards putting their devices on the market. Results: We identified different bodies that are part of the stepwise regulatory pathway of investigational medical devices in Uganda and roles played by each in the regulatory process. Experiences of the medical device teams collected showed that navigation through the regulatory system was different for each team and progress towards market readiness was fuelled by funding, simplicity of device, and mentorship. Conclusion: Medical devices regulation exists in Uganda but is characterised by a landscape that is still in development which thereby affects the progress of investigational medical devices.

AIDS in Africa: A bioanthropological perspective.

The epidemiological characteristics of acquired immunodeficiency syndrome (AIDS) in Africa are reviewed. Infection rates with human immunodeficiency virus 1 (HIV-1) and human immunodeficiency virus 2 (HIV-2) vary across the continent of Africa with the highest infection rates occurring in East and Central Africa. The primary pattern of infection with HIV-1 is characterized by high rates of heterosexual vs. homosexual transmission, a low male to female sex ratio of cases, and high rates of pediatric AIDS. Cultural anthropologists have emphasized variation in human sexual behavior as an important factor in understanding the HIV epidemic. These studies have focussed on understanding the range of sexual risk behaviors present in different cultures and the cultural meanings of these behaviors. Biological anthropologists approach the study of human disease with an interest in human biological variation, evolutionary models, and the interface between biology and behavior. A Bioanthropology Research Agenda for AIDS is proposed which focuses on these three areas. Potential research domains for biological anthropologists include: human biological variation and cofactors of infection and disease, the evolutionary impact of HIV infection, and the interface between biology and behavior and the biological impact of behavior. Working with colleagues in other disciplines, biological anthropologists can assist in furthering understanding of the variables of HIV infection and disease.

Challenging the paradigm: anthropological perspectives on HIV as a chronic disease.

Recently HIV has been framed as a 'manageable' chronic disease in contexts in which access to effective care is reliable. The chronic disease paradigm emphasizes self-care, biomedical disease management, social normalization, and uncertainty. Data from a longitudinal study of patients (N = 949) in HIV care at two sites in Uganda, collected through semistructured interviews and ethnographic data, permit examination of the salience of this model in a high burden, low resource context struggling to achieve the promise of a manageable HIV epidemic. Our data highlight the complexity of the emerging social reality of long-term survival with HIV. Participants struggle to manage stigma as well as to meet the costs involved in care seeking. In these settings, economic vulnerability leads to daily struggles for food and basic services. Reconceptualizing the chronic disease model to accommodate a 'social space,' recognizing this new social reality will better capture the experience of long-term survival with HIV.

Indices to measure risk of HIV acquisition in Rakai, Uganda.

INTRODUCTION: Targeting most-at-risk individuals with HIV preventive interventions is cost-effective. We developed gender-specific indices to measure risk of HIV among sexually active individuals in Rakai, Uganda. METHODS: We used multivariable Cox proportional hazards models to estimate time-to-HIV infection associated with candidate predictors. Reduced models were determined using backward selection procedures with Akaike's information criterion (AIC) as the stopping rule. Model discrimination was determined using Harrell's concordance index (c index). Model calibration was determined graphically. Nomograms were used to present the final prediction models. RESULTS: We used samples of 7,497 women and 5,783 men. 342 new infections occurred among females (incidence 1.11/100 person years,) and 225 among the males (incidence 1.00/100 person years). The final model for men included age, education, circumcision status, number of sexual partners, genital ulcer disease symptoms, alcohol use before sex, partner in high risk employment, community type, being unaware of a partner's HIV status and community HIV prevalence. The Model's optimism-corrected c index was 69.1 percent (95% CI = 0.66, 0.73). The final women's model included age, marital status, education, number of sex partners, new sex partner, alcohol consumption by self or partner before sex, concurrent sexual partners, being employed in a high-risk occupation, having genital ulcer disease symptoms, community HIV prevalence, and perceiving oneself or partner to be exposed to HIV. The models optimism-corrected c index was 0.67 (95% CI = 0.64, 0.70). Both models were well calibrated. CONCLUSION: These indices were discriminative and well calibrated. This provides proof-of-concept that population-based HIV risk indices can be developed. Further research to validate these indices for other populations is needed.

Task shifting for tuberculosis control: a qualitative study of community-based directly observed therapy in urban Uganda.

This qualitative study of task shifting examined tuberculosis (TB) therapy under modified community-based directly observed treatment short-course (CB-DOTS) in Kampala, Uganda. New TB patients selected one of two strategies: home-based DOTS and clinic-based DOTS. Relevant socio-economic characteristics, treatment-seeking experiences and outcomes were assessed over eight months of follow-up. Of 107 patients recruited, 89 (83%) selected home-based DOTS. Sixty-two patients (70%) under home-based DOTS and 16 patients (89%) under clinic-based DOTS had successful outcomes following completion of tuberculosis therapy. Treatment supporters' provision of social support beyond observing drug ingestion contributed to successful outcomes under both strategies. Home-based DOTS provides continuity of social support during therapy, strengthening the potential for treatment success. Conventional health facility-based DOTS can be modified in resource-limited urban Africa to offer a viable DOTS strategy that is sensitive to personal preference. Shifting the task of DOTS support away from only qualified health workers to include laypersons in the patients' social-support network may contribute to meeting World Health Organization (WHO) treatment targets. We recommend an intervention evaluating this modified DOTS strategy on a larger scale in TB high-burden, resource-poor urban settings.

'Slipping through the cracks': policy implications of delays in HIV treatment seeking.

Public health initiatives to 'test and treat' HIV-infected persons require understanding HIV care seeking. A study of 101 HIV-infected women receiving anti-retroviral medications in Kampala, Uganda, examined barriers to HIV care. Participants entered HIV/AIDS care late, despite knowing their risk and having sought care for symptoms. Over half of the participants (51%) reported delays of up to 5 years from when they suspected they were infected to seeking an HIV test. Some women reported that they did not perceive a need to be tested because they 'knew' they had HIV due to their partner's death from AIDS. Once tested, delays in entering HIV specific care ranged from less than 6 months to over 5 years. The most common reason reported for entering HIV care was the occurrence of serious or persistent symptoms. Late presentation for HIV care in this cohort is due to the inability of the medical system to link women to appropriate care. Women 'slip through the cracks' of this system, despite their care seeking behaviours. The inability to provide linkage to care is a challenge at the health system level that threatens the success of 'test and treat' protocols.
