Context Poor adherence to treatment remains a major obstacle to efficient tuberculosis (TB) control in developing countries. Innovative strategies to improve access and adherence to treatment are needed. Objectives To assess the effectiveness of a contextualized intervention strategy aimed at improving patients' adherence to treatment and to evaluate its impact on TB control in a resource-poor country in Africa with prevalent TB infection. Design, Setting, and Patients A cluster randomized controlled trial, conducted between June 2003 and January 2005, at 16 government district health centers in Senegal. Patients older than 15 years with newly diagnosed sputum smear-positive pulmonary TB were randomly assigned to the intervention or control group. Intervention The intervention strategy included reinforced counseling through improved communication between health personnel and patients, decentralization of treatment, choice of directly observed therapy (DOT) supporter by the patient, and reinforcement of supervision activities. In the control group, the usual TB control program procedures remained unchanged. Main Outcome Measure Proportion of patients successfully completing the 8-month course of treatment and the proportion of patients defaulting from treatment. Results A total of 1522 patients were recruited into the study. Treatment was successful for 682 (88%) of 778 patients recruited in the intervention group, and for 563 (76%) of 744 patients recruited in the control group (adjusted risk ratio [RR], 1.18; 95% confidence interval [CI], 1.03-1.34). The proportion of patients defaulting was reduced in the intervention group to 5.5% (n=43) compared with 16.8% (n=125) in the control group (adjusted RR, 0.43; 95% CI, 0.21-0.89). Conclusion The intervention package based on improved patients counseling and communication, decentralization of treatment, patient choice of DOT supporter, and reinforcement of supervision activities led to improvement in patient outcomes compared with the usual TB control procedures. This approach may be generalized in the context of TB control programs in resource-poor countries.

This paper questions the view that performance-based financing (PBF) in the health sector is an effective, efficient and equitable approach to improving the performance of health systems in low-income and middle-income countries (LMICs). PBF was conceived as an open approach adapted to specific country needs, having the potential to foster system-wide reforms. However, as with many strategies and tools, there is a gap between what was planned and what is actually implemented. This paper argues that PBF as it is currently implemented in many contexts does not satisfy the promises. First, since the start of PBF implementation in LMICs, concerns have been raised on the basis of empirical evidence from different settings and disciplines that indicated the risks, cost and perverse effects. However, PBF implementation was rushed despite insufficient evidence of its effectiveness. Second, there is a lack of domestic ownership of PBF. Considering the amounts of time and money it now absorbs, and the lack of evidence of effectiveness and efficiency, PBF can be characterised as a donor fad. Third, by presenting itself as a comprehensive approach that makes it possible to address all aspects of the health system in any context, PBF monopolises attention and focuses policy dialogue on the short-term results of PBF programmes while diverting attention and resources from broader processes of change and necessary reforms. Too little care is given to system-wide and long-term effects, so that PBF can actually damage health services and systems. This paper ends by proposing entry points for alternative approaches.

BackgroundPrefilled syringes are the standard in developed countries but logistic and financial barriers prevent their widespread use in developing countries. The current study evaluated use of a compact, prefilled, autodisable device (CPAD) to deliver pentavalent vaccine by field actors in Senegal and Vietnam.MethodsWe conducted a logistic, programmatic, and anthropological study that included a) interviews of immunization staff at different health system levels and parents attending immunization sessions; b) observation of immunization sessions including CPAD use on oranges; and c) document review.ResultsRespondents perceived that the CPAD would improve safety by being non-reusable and preventing needle and vaccine exposure during preparation. Preparation was considered simple and may reduce immunization time for staff and caretakers. CPAD impact on cold storage requirements depended on the current pentavalent vaccine being used; in both countries, CPAD would reduce the weight and volume of materials and safety boxes thereby potentially improving outreach strategies and waste disposal. CPAD also would reduce stock outages by bundling vaccine and syringes and reduce wastage by using a non-breakable plastic presentation. Respondents also cited potential challenges including ability to distinguish between CPAD and other pharmaceuticals delivered via a similar mechanism (such as contraceptives), safety, and concerns related to design and ease of administration (such as activation, ease of delivery, and needle diameter and length).ConclusionsCompared to current pentavalent vaccine presentations in Vietnam and Senegal, CPAD technology will address some of the main barriers to vaccination, such as supply chain issues and safety concerns among health workers and families. Most of the challenges we identified can be addressed with health worker training, minor design modifications, and health messaging targeting parents and communities. Potentially the largest remaining barrier is the marginal increase in pentavalent cost – if any – from CPAD use, which we did not assess in our study.

The objectives of this study were: to compare the prevalence of hypertension, overweight and obesity in rural (Ferlo) and urban (Dakar) Senegalese populations aged 50 and over. The survey was conducted on individuals aged 50 and older living in the rural area (N=478) and in the urban area (N=220). We have collected data about age, gender, marital status, education level, and knowledge, treatment of hypertension, height, weight and blood pressure. We have observed that overweight and obesity were more prevalent in the urban area (Dakar) than in the rural one (Ferlo). The risk of overweight or obesity decreased when age increased, and women had weight problems more often than men. The prevalence of arterial hypertension was lower in rural area (55.86%) than in Dakar (66.36%), but increased at an older age. However, the logistic regression showed that these increased proportion of hypertension in Dakar is linked to the more important proportion of overweight and obese people in this area. Moreover, rates of knowledge, treatment and control of hypertension are particularly low in the rural area of Senegal. In conclusion, age-associated diseases should be better managed in Senegal, particularly in rural areas.

Health priorities defined by international organizations and technical and financial partners focus on diseases considered to be ?priorities? to the detriment of neglected diseases, which are perceived as being more important at the local level due to their impact on the already limited health systems. We describe how health actors within healthcare structures adjust and adapt to public health requirements.

How do non-Western societies envisage the relationship between the body and ageing? The present work aimed to shed light on this question by exploring how adult men and women of different ages living in Dakar, Senegal, view their bodies. A quantitative methodology was selected, and this study was carried out on a sample of 1,000 dwellers of the Senegalese capital, aged 20 and older. This sample was constructed using the quota method in order to strive for representativeness. Results indicate that appearance was highly important for Senegalese women and men, and for younger and older adults alike. As in Western cultures, beauty and youth were strongly connected. The large majority of Senegalese women and men were satisfied with their looks across the lifespan. However, older women were slightly less satisfied, consistent with the double standard hypothesis. Little discrepancy was found between felt age and chronological age throughout the entire lifecourse, arguing against an ageless self hypothesis in this African population. The mask of ageing hypothesis was also rejected, as men's and women's identification with their body did not diminish significantly across age. These observations from an African perspective call for greater attention to the ageing process in non-Western societies in order to challenge hypotheses developed in Western societies and understand more broadly the role of culture.
