Preferences for hospital quality in Zambia: results from a discrete choice experiment

Abstract

This study reports on the results of a discrete choice experiment undertaken in Zambia to assess the factors influencing the demand for hospital care in Zambia, in particular the role of (perceived) quality and trade-offs between price and quality. Valuations of quality were evaluated for the treatment of two acute medical conditions, cerebral malaria in adults and acute pneumonia in children. Marginal utilities and willingness-to-pay for attributes of quality of hospital care were estimated, together with the influence of socioeconomic characteristics on these valuations and the extent of non-linearities in valuations of time and money. We find the technical quality of care, as represented by the thoroughness of examination, to be the most important quality attribute, followed by staff attitudes and drug availability. Valuations of examination thoroughness increase with increasing socioeconomic status. The disutility of cost was found to decrease with higher socioeconomic status, as was the value of drug availability. The implications of the findings for Zambian hospital sector reforms are discussed.

How to make rural jobs more attractive to health workers. Findings from a discrete choice experiment in Tanzania

“…Although DCEs have become a common method of identifying preferences in health economics, few attempts at applying DCEs to health personnel in developing countries have been undertaken. Chomitz et al (1998) made use of a variant of a stated preference method with doctors in Indonesia, Mangham (2006) conducted a DCE of nurses in Malawi and another DCE has recently been conducted in Ethiopia (Hanson and Jack, 2007). However, to our knowledge, the preference structure of Tanzanian health personnel has not been identified using a DCE or similar quantitative exercise.…”

Preferências para o trabalho na atenção primária por estudantes de medicina em Minas Gerais, Brasil: evidências de um experimento de preferência declarada

“…Os DCE têm sido aplicados em diversos países para fundamentar decisões em relação às políticas de saúde, planejamento e alocação de recursos, sobretudo para orientar políticas de atração e retenção de recursos humanos em saúde em áreas de maior necessidade 11,12,13,14 . Em anos recentes, registrou-se um uso crescente desta técnica 15,16,17,18,19,20,21,22,23,24,25 . Acompanhando esse cenário recente e considerando a ausência de estudos do tipo no Brasil, o presente estudo teve como objetivo realizar um DCE a fim de investigar preferências por atributos de emprego de médicos na atenção primária à saúde.…”

Thought for Food: Understanding Educational Disparities in Food Consumption

“…Design size We choose to present 18 choice sets to each individual, which is seen as a practical limit before boredom sets in (Hanson et al, 2005). Using 5 blocks of 18 choice sets ensures that the total number of choice sets generated is 90, which gives a comfortable buffer to identify all main effects and two-way interactions of the attribute levels.…”
