The role of leadership in people-centred health systems: a sub-national study in The Gambia.

Recently, increasing attention has been given to behavioural and relational aspects of the people who both define and shape health systems, placing them at the core. A growing refrain includes the assertion that important decisions determining health system performance, including agenda setting, policy formulation and policy implementation, are made by people. Within this actor-oriented approach, good leadership has been identified as a key contributing factor in health systems strengthening. However, leadership remains ill-defined and under-researched, especially in resource-limited settings, and understanding the links between leadership and health outcomes remains a challenge. We explore the concept and practice of healthcare leadership at sub-national level in a low-income country setting, using a people-centric research methodology. In June and July 2013, 15 in-depth interviews were conducted with key informants in formal healthcare leadership roles across urban, peri-urban and rural settings of The Gambia, West Africa. Participants included the entire spectrum of Regional Health Team (RHT) Directors and Chief Executive Officers of all government hospitals, as well as one clinical officer-in-charge in a secondary-level major health centre. We found reference to several important aspects of, and approaches to, leadership, including (i) setting a clear vision; (ii) engendering shared leadership; and (iii) paying attention to human relations in management. Participants described attending to constituencies in government, international development agencies and civil society, as well as to the populations they serve. By illuminating the multi-polar networks within which these leaders are embedded, and through which they operate, we provide insight into the complex 'organizational ecology' of the Gambian health system. There is a need to further research and develop healthcare leadership across all levels, within various political, socio-economic and cultural contexts, in order to better work with a range of health actors and to engage them in identifying and acting upon opportunities for health systems strengthening.

Framing the tax and health nexus: a neglected aspect of public health concern.

Previous studies have described various associations between tax policy and health. Here we propose a unifying conceptual framework of 'Five R's' to stimulate awareness about the importance of tax to health improvement. First, tax can improve representation and democratic accountability, and help make governments more responsive to the needs of its citizens. Second, tax can create a revenue stream for a universal pool of public finance for health care and other public services. Third, progressive taxation when combined with appropriate public spending can help redistribute wealth and income and mitigate social and health inequalities. Fourth, the re-pricing of harmful products (e.g. tobacco, alcohol and unhealthy food) can help reduce their consumption. Fifth, taxation provides a route by which certain harmful industries can be regulated. The paper also discusses the barriers that hinder the full potential for taxation to be used to improve health, including: weak tax administrations, large 'shadow economies', international trade liberalisation, tax avoidance, transfer pricing by transnational corporations and banking secrecy. We suggest that a greater awareness of the manifold associations between tax and health will encourage health practitioners to actively promote fairer and better taxation, thereby helping to improve health and reduce health inequalities.

The epilepsy treatment gap in rural Tanzania: A community-based study in adults.

PURPOSE: Most people with epilepsy (PWE) in low-income countries are not treated. We identified risk factors for the epilepsy treatment gap in rural Tanzania. METHODS: We identified adult PWE in a community-based prevalence study. Factors associated with failure to access or default from medical care were identified using logistic regression modelling. RESULTS: A total of 291 PWE were included, of whom 253 (86.9%) had presented to medical services. Failure to present was positively associated with using alcohol (odds ratio (OR) 4.20; 95% confidence interval (CI) 1.63 to 10.82) or attending traditional healers (OR 2.62; CI 1.00 to 6.83) and inversely associated with having completed primary education (OR 0.33; CI 0.11 to 0.96). Default from treatment was associated with being male (OR 3.35; CI 1.39 to 8.09), having a seizure-related injury (OR 2.64; CI 1.12 to 6.19), believing in a supernatural cause for epilepsy (OR 5.44; CI 1.48 to 19.94) or having no expressed knowledge of cause (OR 5.29; CI 1.60 to 17.52). Cases less likely to default had a duration of epilepsy greater than 10 years (OR 0.28; CI 0.09 to 0.90) or had previously received a seizure-related diagnosis (OR 0.25; CI 0.09 to 0.65). Of all 291 PWE included, 118 denied taking AEDs; the epilepsy treatment gap in this population was therefore 40.5% (95% CI 34.9 to 46.2). CONCLUSION: Interventions to improve access to education and to support formal diagnoses may promote access to, and retention under, medical care for PWE in rural Tanzania and in other low-income countries.

Prevalence of active epilepsy in rural Tanzania: a large community-based survey in an adult population.

PURPOSE: To estimate the prevalence of active epilepsy in adults in an established demographic surveillance site in rural Tanzania. To describe the clinical characteristics of epilepsy and to estimate the treatment gap in this population. METHODS: A pilot study established that a previously validated screening questionnaire was sensitive for detecting cases of epilepsy in a Kiswahili-speaking Tanzanian population. A door-to-door census of the adult population (total 103,026) used the screening questionnaire to identify possible cases of epilepsy, who were then assessed by a research doctor to establish a diagnosis of epilepsy or otherwise. The prevalence of active epilepsy in this population was estimated with age-standardisation to the WHO standard population. Seizure types and epilepsies were classified according to current recommendations of the International League Against Epilepsy. The treatment gap for epilepsy was estimated based on antiepileptic drug use as reported by cases. RESULTS: Two hundred and ninety-one cases of active epilepsy, all with convulsive seizures, were identified. The age-standardised prevalence was 2.91/1000 adults (95% CI 2.58-3.24); the crude prevalence adjusted for non-response was 3.84/1000 adults (95% CI 3.45-4.20). Focal-onset seizures accounted for 71.5% of all cases identified. The treatment gap was 68.4% (95% CI 63.0-73.7). CONCLUSIONS: This is one of the largest community-based studies of the prevalence of epilepsy in adults conducted in sub-Saharan Africa to date. We identified a lower prevalence than has previously been described in this region. The high proportion of focal onset seizures points to a large burden of acquired, and possibly preventable, epilepsy in this population. A treatment gap of 68.4% confirms that interventions to raise awareness of the treatable nature of epilepsy are warranted in this and similar populations.
