Understanding public health providers’ preferences for interventions against informal payment in Tanzania: a discrete choice experiment

Abstract

Abstract Background Informal payments are regressive. They can limit the access to quality healthcare, particularly of the most vulnerable, and are potentially catastrophic. Little is known in terms of providers' preferences for interventions. Methods We conducted a cross-sectional discrete choice experiment (DCE) among 432 health providers from 42 public health facilities (hospitals and health centres) in seven districts from Pwani region and five districts from Dar es Salaam region. The DCE attributes were derived from a scoping literature review, qualitative interview from 27 key informants from three districts, and through workshop with health providers, managers and policy makers. The final DCE survey tool included 12 unlabeled choice sets, each describing two hypothetical jobs that varied across six attributes: mode of payment, supervision at facility, opportunity for private practice, awareness and monitoring, measures against informal payment, and incentive payment for lack informal payment in the past 6 months. Multinomial logit and mixed multinomial logit methods were used to estimate preferences for the attributes. Results All attribute-levels, apart from supervision at the facility level, were significantly influencing health providers' choice decisions for job type (p < 0.001). The most preferred attributes were measures for awareness creation and monitoring -i.e. preferences were significantly higher for facility with noticeboard (coefficient 0.39, 95% CI 0.29 -0.48 ), followed by provision of receipts (0.34, 0.24 -0.44) and presence of hotline number for reporting corrupt practices (0.26, 0.17 -0.35). Opportunity for private practice was significantly preferred (0.38, 0.31-045) and job preference increases as salary top-up increases (0.06, 0.05-0.7). The less preferred attributes were cash payment for healthcare (-0.27, -0.35- -0.19) and disciplinary measures at the district (-0.15, -0.23 - -0.07) or facility level (-0.10, -0.17- -0.03).
