Objective: To investigate what influences patients’ health care decisions, and what the implications are for the provision of information on the quality of health care providers to patients. Data Sources/Study Setting: Dutch patient samples between November 2006 and February 2007. Study Design: Discrete choice experiments were conducted in three patient groups to explore what influences choice for health care provider. Data collection: Data were obtained from 616 patients with knee arthrosis, 368 patients with chronic depression, and 421 representatives of patients with Alzheimer’s Disease. Principle findings: The three patients groups chose health care providers on a different basis. The most valued attributes were: effectiveness and safety (knee arthrosis); continuity of care and relationship with the therapist (chronic depression); expertise (Alzheimer’s disease). Preferences differed between sub-groups, mainly in relation to patients’ choice profiles, severity of disease and some background characteristics. Conclusions: This study showed that there is substantial room for (quality) information about health care providers in patients’ decision processes. This information should be tailor-made, targeting specific patient segments, because different actors and factors play a part in their search and selection process.
