RESUMEN
BACKGROUND: To ensure efficient use of resources within outpatient services, constant patient flow is vital. This can be achieved by addressing the wishes and needs of all relevant stakeholders. MATERIALS AND METHODS: The present study aims to show how the needs and present satisfaction of patients and referring physicians can be determined in the context of an outpatient cataract service. It presents the conclusions that can be drawn for the design of the service. To assess needs and satisfaction, we developed a patient questionnaire and a referring physician questionnaire. Promoters and detractors for referral were identified following the concept of the net promoter score, a market research instrument. RESULTS: 339 (38%) patients and 26 (45%) referring physicians of the main referring group answered the questionnaires. The most important characteristics for referring physicians were quality of treatment, patient satisfaction, and communication in case of queries as well as speed of sending the doctor's letter. When making their decision on a cataract centre, the patients prioritised professional reputation, previous experience with the clinic, and recommendation of their ophthalmologist as well as customary appointment scheduling. CONCLUSION: The two groups influence each other's recommendation or choice. Simultaneous analysis of patients and referring physicians is therefore essential. Overall, patients and referring physicians are highly satisfied with the cataract service of the university medical centre. Beyond that, however, various potentials for improvement could be identified. In summary, this report describes a comprehensive approach to assess needs and satisfaction of patients and referring physicians in an outpatient clinic trying to sustainably improve patient care.
