Decolonizing Global Health Education: Rethinking Institutional Partnerships and Approaches.

Global health often entails partnerships between institutions in low- and middle-income countries (LMICs) that were previously colonized and high-income countries (HICs) that were colonizers. Little attention has been paid to the legacy of former colonial relationships and the influence they have on global health initiatives. There have been recent calls for the decolonization of global health education and the reexamination of assumptions and practices under pinning global health partnerships. Medicine's role in colonialism cannot be ignored and requires critical review. There is a growing awareness of how knowledge generated in HICs defines practices and informs thinking to the detriment of knowledge systems in LMICs. Additionally, research partnerships often benefit the better-resourced partner. In this article, the authors offer a brief analysis of the intersections between colonialism, medicine, and global health education and explore the lingering impact of colonialist legacies on current global health programs and partnerships. They describe how "decolonized" perspectives have not gained sufficient traction and how inequitable power dynamics and neocolonialist assumptions continue to dominate. They discuss 5 approaches, and highlight resources, that challenge colonial paradigms in the global health arena. Furthermore, they argue for the inclusion of more transfor mative learning approaches to promote change in attitudes and practice. They call for critical reflection and concomitant action to shift colonial paradigms toward more equitable partnerships in global education.

Trends in immunization completion and disparities in the context of health reforms: the case study of Tanzania.

BACKGROUND: Of global concern is the decline in under five children mortality which has reversed in some countries in sub Saharan Africa (SSA) since the early 1990 s which could be due to disparities in access to preventive services including immunization. This paper is aimed at determining the trend in disparities in completion of immunization using Tanzania Demographic and Health Surveys (DHS). METHODS: DHS studies randomly selected representative households from all regions in Tanzania since 1980 s, is repeated every five years in the same enumeration areas. The last three data sets (1990, 1996 and 2004) were downloaded and analyzed using STATA 9.0. The analysis included all children of between 12-23 months who would have completed all vaccinations required at 12 months. RESULTS: Across the time periods 1990, 1996 to 2004/05 the percentage of children completing vaccination was similar (71.0% in 1990, 72.7% in 1996 and 72.3% in 2005). There was no disparity in completion of immunization with wealth strata in 1990 and 1996 (p > 0.05) but not 2004. In 2004/05 there was marked disparity as most poor experienced significant decline in immunization completion while the least poor had significant increase (p < 0.001). All three periods children from households whose head had low education were less likely to complete immunization (p < 0.01). CONCLUSION: Equity that existed in 1990 and more pronounced in 1996 regressed to inequity in 2005, thus though at national level immunization coverage did not change, but at sub-group there was significant disparity associated with the changing contexts and reforms. To address sub-group disparities in immunization it is recommended to adopt strategies focused at governance and health system to reach all population groups and most poor.

Understanding the Role of Accredited Drug Dispensing Outlets in Tanzania's Health System.

INTRODUCTION: People in many low-income countries access medicines from retail drug shops. In Tanzania, a public-private partnership launched in 2003 used an accreditation approach to improve access to quality medicines and pharmaceutical services in underserved areas. The government scaled up the accredited drug dispensing outlet (ADDO) program nationally, with over 9,000 shops now accredited. This study assessed the relationships between community members and their sources of health care and medicines, particularly antimicrobials, with a specific focus on the role ADDOs play in the health care system. METHODS: Using mixed methods, we collected data in four regions. We surveyed 1,185 households and audited 96 ADDOs and 84 public/nongovernmental health facilities using a list of 17 tracer drugs. To determine practices in health facilities, we interviewed 1,365 exiting patients. To assess dispensing practices, mystery shoppers visited 306 ADDOs presenting one of three scenarios (102 each) about a child's respiratory symptoms. RESULTS AND DISCUSSION: Of 614 household members with a recent acute illness, 73% sought outside care-30% at a public facility and 31% at an ADDO. However, people bought medicines more often at ADDOs no matter who recommended the treatment; of the 581 medicines that people had received, 49% came from an ADDO. Although health facilities and ADDOs had similar availability of antimicrobials, ADDOs had more pediatric formulations available (p<0.001). The common perception was that drugs from ADDOs are more expensive, but the difference in the median cost to treat pneumonia was relatively minimal (US$0.26 in a public facility and US$0.30 in an ADDO). Over 20% of households said they had someone with a chronic condition, with 93% taking medication, but ADDOs are allowed to sell very few chronic care-related medicines. ADDO dispensers are trained to refer complicated cases to a health facility, and notably, 99% of mystery shoppers presenting a pneumonia scenario received an antimicrobial (54%), a referral (90%), or both (45%), which are recommended practices for managing pediatric pneumonia. However, one-third of the dispensers needlessly sold antibiotics for cold symptoms, and 85% sold an antibiotic on request. In addition, the pneumonia scenario elicited more advice on handling the illness than the cold symptoms scenario (61% vs. 15%; p<0.0001), but overall, only 44% of the dispensers asked any of the shoppers about danger signs potentially associated with pneumonia in a child. CONCLUSION: ADDOs are the principal source of medicines in Tanzania and an important part of a multi-faceted health care system. Poor prescribing in health facilities, poor dispensing at ADDOs, and inappropriate patient demand continue to contribute to inappropriate medicines use. Therefore, while accreditation has attempted to address the quality of pharmaceutical services in private sector drug outlets, efforts to improve access to and use of medicines in Tanzania need to target ADDOs, public/nongovernmental health facilities, and the public to be effective.

What roles do accredited drug dispensing outlets in Tanzania play in facilitating access to antimicrobials? Results of a multi-method analysis.

BACKGROUND: People in low-income countries purchase a high proportion of antimicrobials from retail drug shops, both with and without a prescription. Tanzania's accredited drug dispensing outlet (ADDO) program includes dispenser training, enforcement of standards, and the legal right to sell selected antimicrobials. We assessed the role of ADDOs in facilitating access to antimicrobials. METHODS: We purposively chose four regions, randomly selected three districts and five wards per district. Study methods included interviews at 1200 households regarding care-seeking for acute illness and knowledge about antimicrobials; mystery shoppers visiting 306 ADDOs posing as a caregiver of a child with 1) pneumonia, 2) mild acute respiratory infection (ARI), or 3) a runny nose and request for co-trimoxazole; and audits of antimicrobial availability and prices at 84 public health facilities (PHFs) and 96 ADDOs. RESULTS: Four hundred sixty seven (76 %) members from 367 (77 %) households had recently sought care outside the home for acute illness; 128 had purchased antimicrobials, of which 61 % had been recommended by a doctor or nurse and 32 % by an ADDO dispenser. Only 29 % obtained the antimicrobial at a PHF, whereas, 48 % purchased them at an ADDO. Most thought that ADDOs are convenient place for care, usually have needed medicines, and have high quality services and products, contrasting with 66 % who reported dissatisfaction with PHF waiting times and 56 % with medicine availability. One-third (34 %) of mystery shoppers presenting the mild ARI scenario were inappropriately sold an antimicrobial and 85 % were sold one on request; encouragingly, 99 % presenting a case of pneumonia received either an antimicrobial, referral to a trained provider, or request to bring the child for examination. Overall, 63 and 60 % of the 15 tracer antimicrobials were in stock in ADDOs and PHFs, respectively; ADDOs had significantly more antimicrobial formulations for children available (83 vs. 51 %). Of 369 records of antimicrobial sales in 47 ADDOs, 63 % were dispensed on prescription. CONCLUSION: ADDOs have increased access to antimicrobials in Tanzania. Community members see them as integral to the health system. Antimicrobials are overused due to poor ADDO dispensing, poor PHF prescribing, and inappropriate public demand. Multi-pronged interventions are needed to address all determinants.

Food insecurity and coping strategies among people living with HIV in Dar es Salaam, Tanzania.

Food insecurity and malnutrition seriously impedes efforts to control HIV/AIDS in resource poor countries. This study was carried out to assess food security, and coping strategies among people living with HIV/AIDS (PLHIV) attending Care and Treatment Centre (CTC) in Dar es Salaam, Tanzania. A structured questionnaire was used to interview randomly selected adults (18 years) who were HIV positive who have just been eligible for anti-retroviral treatment (ART) in a CTC or one who has started ART but not more than four weeks has elapsed. A total of 446 (females=67.9%; males= 32.1%) people living with HIV/AIDS attending CTC were interviewed. About three quarters (73.1%) of the respondents were 25-44 years old and most (43.9%) were married. Two thirds (66.7%) of the respondents had primary school education. Seventy percent reported to have a regular income and 63.7% with a monthly income of less than US$ 154. More than half (52.2%) of the respondents were food insecure. Food insecurity was similar in both males (54.6%) and females (51.2%). However, food insecurity was least (48.2%) among those who were single and highest (57.7%) among those cohabiting. Low level of food insecurity was associated with having completed primary education (Adjusted OR=0.27; 95% CI, 0.09-0.82) and high income (>US $154) (OR=0.10; 95% CI, 0.01-0.67). Reporting two or less meals increased the likelihood of food insecurity (OR=4.2; 95% CI1.7-9.8). Low frequency of meals was significantly more prevalent (18.6%) among those. 45 years than among 35-44 years old respondents (6.7%) (P=0.04). Borrowing money (55.8%) and taking less preferred foods (53.3%) were the most common coping strategies. In conclusion, food insecurity is a significant problem among people living with HIV in Dar es Salaam which might significantly affect compliance to care and support. The study suggests that counselling of PLHIV before anti-retroviral treatment programmes should devise special strategies targeting those with low education, low income and low frequency of meals.

Equity and utilization of preventive health care services. The case of immunization completion among children 12-23 months in Kagera region Tanzania.

OBJECTIVE: The aim of this study was to determine factors associated with completion of immunization as an input in to strategies to raise the immunization coverage in Tanzania. METHODS: This study used a panel data collected over four survey rounds at a minimum of six months apart to determine the causes of failure to complete immunization in Tanzania. The data were collected during between 1991 and 1994 in Kagera region Tanzania among children 12-23 months old. Data analysis was done using Statistical Analysis Software (SAS) version 9.1. Pooled logistic regression was used to determine the likelihood odds ratio of completing immunization. RESULTS: The study observed 550 children contributing 1541 children observation rounds across all panels. Immunization coverage was 87.7 percent and factors that significantly (p<0.05) increasing completion of immunization were having more than three under five children, high mother's education, being urban, road passable through out the year and high economic status. If head of household was a female compared to male it significantly reduced the odds of completing immunization. CONCLUSIONS: Strategies to improve immunization coverage have to give priority to households headed by a female, poor and those with poor access to health care.

Decentralizing EPI services and prospects for increasing coverage: the case of Tanzania.

Primary health Care (PHC) strategies were adopted widely in 1978 after the Alma Ata declaration to improve accessibility to health services and the health of the people. Of the strategies of PHC was the decentralization of health services to lower levels in order to enhance participation and responsiveness of the health system to local problems. While PHC was being promoted vertical programmes such as the expanded programme on immunization (EPI) were also being promoted and achieved substantial benefits. However, almost 25 years later many countries have not been able to achieve these health goals. This study addressed the question: Can we make the process of health care decentralization more likely to support health system and EPI goals? This study analysed the experience of EPI decentralization at national, regional and district levels. Several stakeholders were identified who were supportive and others who were non-supportive of the process. Community support to EPI measured by using willingness to pay (WTP) for kerosene (to keep vaccines cool) was low. It was significantly (p < 0.05) associated with whether providers in the nearest health facility properly attended the target population and whether the providers in the facility were available when needed. There was a substantial stakeholder support and opposition to the process of decentralization at the district level. Community support was not high possibly due to the perceived non-availability of the service providers and their lack of awareness of the population they serve. It was proposed that reforms should give priority to the involvement of communities and peripheral health facility providers in the process.
