RESUMEN
BACKGROUND: While patient-centred care improves patient outcomes, studies have shown that medical students become less patient-centred with time, so it is crucial to devise interventions that prevent this. We sought to determine whether first-year medical students who had a structured home-based interview with a chronically ill patient became more patient-centred than those who had a sham intervention. METHODS: This randomised controlled trial assigned first-year students from the University of Bern, Switzerland, to either an interview with a chronically ill patient at the patient's home or to a sham comparator. We used the PPOS-D12 questionnaire to measure students' levels of patient-centredness at baseline, and changes in these levels during their longitudinal primary care clerkship. RESULTS: A total of 317 students participated. Patient-centred attitudes increased during the study. A home-based interview with a chronically ill patient had no additional effect. Being female and having been exposed to patients before medical school were associated with being more patient-centred at baseline. Students were less patient-centred than their General Practitioner teachers. CONCLUSIONS: A structured, home-based interview with a chronically ill patient did not change students' patient-centred attitudes, so cannot be recommended as a way to influence those attitudes. However, patient-centred attitudes increased during the students' first year of study, possibly because of their longitudinal primary care clerkship.
