BackgroundDespite the growing importance of the Accountability for Reasonableness (A4R) framework in priority setting worldwide, there is still an inadequate understanding of the processes and mechanisms underlying its influence on legitimacy and fairness, as conceived and reflected in service management processes and outcomes. As a result, the ability to draw scientifically sound lessons for the application of the framework to services and interventions is limited. This paper evaluates the experiences of implementing the A4R approach in Mbarali District, Tanzania, in order to find out how the innovation was shaped, enabled, and constrained by the interaction between contexts, mechanisms and outcomes.MethodsThis study draws on the principles of realist evaluation -- a largely qualitative approach, chiefly concerned with testing and refining programme theories by exploring the complex interactions of contexts, mechanisms, and outcomes. Mixed methods were used in data collection, including individual interviews, non-participant observation, and document reviews. A thematic framework approach was adopted for the data analysis.ResultsThe study found that while the A4R approach to priority setting was helpful in strengthening transparency, accountability, stakeholder engagement, and fairness, the efforts at integrating it into the current district health system were challenging. Participatory structures under the decentralisation framework, central government's call for partnership in district-level planning and priority setting, perceived needs of stakeholders, as well as active engagement between researchers and decision makers all facilitated the adoption and implementation of the innovation. In contrast, however, limited local autonomy, low level of public awareness, unreliable and untimely funding, inadequate accountability mechanisms, and limited local resources were the major contextual factors that hampered the full implementation.ConclusionThis study documents an important first step in the effort to introduce the ethical framework A4R into district planning processes. This study supports the idea that a greater involvement and accountability among local actors through the A4R process may increase the legitimacy and fairness of priority-setting decisions. Support from researchers in providing a broader and more detailed analysis of health system elements, and the socio-cultural context, could lead to better prediction of the effects of the innovation and pinpoint stakeholders' concerns, thereby illuminating areas that require special attention to promote sustainability.

The success of the Community-Directed Treatment (ComDT) approach in the control of onchocerciasis and filariasis has caught the attention of other disease control programmes. In this study the ComDT approach was implemented and compared with the school-based approach for control of schistosomiasis and soil-transmitted helminthiasis among school-age children in Lushoto District, Tanzania. This was a qualitative study, consisting of in-depth interviews with village leaders, community drug distributors (CDDs) and schoolteachers, as well as focus group discussions with separate groups of mothers and fathers to assess the perceptions and experiences of the villagers on the implementation of the two approaches. It was found that the villagers accepted the ComDT approach and took the responsibility of selecting the CDDs, organizing and implementing their own method of distributing drugs to the school-age children in their villages. The ComDT approach was well received and was successfully implemented in the villages. Although the villagers pointed out the limitation in reaching the non-enrolled children in the school-based approach, they also expressed satisfaction with this approach. This study suggests that the ComDT approach is well accepted and can be implemented effectively to ensure better coverage of especially non-enrolled school-age children.

Despite multiple efforts to strengthen health systems in low and middle income countries, intended sustainable improvements in health outcomes have not been shown. To date most priority setting initiatives in health systems have mainly focused on technical approaches involving information derived from burden of disease statistics, cost effectiveness analysis, and published clinical trials. However, priority setting involves value-laden choices and these technical approaches do not equip decision-makers to address a broader range of relevant values -such as trust, equity, accountability and fairness -that are of concern to other partners and, not least, the populations concerned. A new focus for priority setting is needed. Accountability for Reasonableness (AFR) is an explicit ethical framework for legitimate and fair priority setting that provides guidance for decision-makers who must identify and consider the full range of relevant values. AFR consists of four conditions: i) relevance to the local setting, decided by agreed criteria; ii) publicizing priority-setting decisions and the reasons behind them; iii) the establishment of revisions/appeal mechanisms for challenging and revising decisions; iv) the provision of leadership to ensure that the first three conditions are met.REACT -"REsponse to ACcountable priority setting for Trust in health systems" is an EU-funded five-year intervention study started in 2006, which is testing the application and effects of the AFR approach in one district each in Kenya, Tanzania and Zambia. The objectives of REACT are to describe and evaluate district-level priority setting, to develop and implement improvement strategies guided by AFR and to measure their effect on quality, equity and trust indicators. Effects are monitored within selected disease and programme interventions and services and within human resources and health systems management. Qualitative and quantitative methods are being applied in an action research framework to examine the potential of AFR to support sustainable improvements to health systems performance. This paper reports on the project design and progress and argues that there is a high need for research into legitimate and fair priority setting to improve the knowledge base for achieving sustainable improvements in health outcomes.

The prevalence of urinary schistosomiasis among schoolchildren in Pangani District (Tanzania) was assessed rapidly by a questionnaire approach. Based on the results, a strategy of selective treatment with praziquantel was adopted. Eleven primary schools in Mwera Division, Pangani District, with about 2500 schoolchildren were included in a control programme for urinary schistosomiasis. Macro- and microscopic haematuria diagnosed visually and with urine reagent strips was used as an indirect indicator of Schistosoma haematobium infection. Intensity of infection among children was monitored in class 5 (median age 14 years, range 11-17) by urine filtration techniques. Treatment was administered as 40 mg/kg praziquantel in a single dose at the beginning of the school year. The programme was implemented by schoolteachers and coordinated by the District Health Management Team in collaboration with the District Education Office. Teachers were responsible for carrying out all programme activities. Community participation was through collaboration with Teachers-Parents Associations and Village Health Committees. Coverage at yearly (1995-99) examination varied from 67.7% to 80.3%. Prevalence of haematuria decreased from 51.2% (range 22.2-89.5%) at baseline to 23.4% (range 5.8-56.7%) in 1999, a reduction of 54.3%. Macrohaematuria was 21.2% at baseline and 7.2% in 1999, a reduction of 66.0%. Prevalence of infection in class 5 was reduced by 71.4% and geometric mean intensity of positives reduced from 71 eggs/10 mL (95% confidence interval [CI] 52.5-97.7) to 28 eggs/10 mL (95% CI 25.7-55.0), a reduction of 60.6%. Teachers were highly committed, and secured community participation and a smooth implementation of the programme. The community accepted the introduction of a cost-recovery system, whereby parents pay for the treatment of children with episodes of visible haematuria during the school year. Communities also participated in the improvement of sanitary installations at the schools.
