Background: By assessing patient safety culture, healthcare providers can identify areas for improvement in patient safety culture. To achieve this, these assessment outcomes have to be relevant and presented clearly. The aim of our study was to explore healthcare professionals' views on the feedback of a patient safety culture assessment. Methods: Twenty four hospitals participated in a patient safety culture assessment in 2012. Hospital departments received feedback in a report and on a website. In a survey, we evaluated healthcare professionals' views on this feedback and the effect of additional information about patient safety culture improvement strategies on the appraisal of the feedback. 20 hospitals participated in part I (evaluation of the report), 13 hospitals participated in part II (evaluation of the website). Results: Healthcare professionals (e.g. members of staff and department heads/managers) rated the feedback in the report and on the website positively (average mean on different aspects = 7.2 on a scale from 1 to 10). Interpreting results was sometimes difficult, and information was sometimes lacking, like specific recommendations and improvement strategies. The provision of additional general information on patient safety culture improvement strategies resulted only in a higher appraisal of the attractiveness (lay-out) of the report and the understandability of the feedback report. The majority (84 %) of the healthcare professionals agreed or partly agreed that the feedback on patient safety culture stimulated actions to improve patient safety culture. However, a quarter also stated that although the feedback report provided insight into the patient safety culture, they did not know how to improve patient safety culture in their hospital. Conclusions: Healthcare professionals seem to be positive about the feedback on patient safety culture and its effect on stimulating patient safety culture improvement. To optimally tune feedback on patient safety culture towards healthcare professionals, the following might help: 1) pay attention to the understandability of outcomes for its intended users; and 2) create feedback that is tailored towards specific hospital departments.
