BACKGROUND Pay-for-performance (P4P) has become a popular approach to increase effectiveness and efficiency in healthcare. So far, there is little evidence regarding the potential of P4P in the German healthcare setting. The aim of this study was to determine the impact of P4P on the quality of care in cataract surgery. METHODS In 2012, a P4P program was implemented in a German surgical centre for ophthalmology. Five quality measures regarding process quality, outcomes, and patient satisfaction were measured over a period of 4.5 years. The P4P scheme consisted of bonus and penalty payments accounting for five per cent of total compensation. Overall, 1657 P4P cases were examined and compared with 4307 control cases. Interrupted time series and group comparisons were conducted to identify quality and spill-over effects. RESULTS We found a positive impact on process quality and patient satisfaction before the implementation of the P4P scheme, but declining trends during and after the implementation. Our findings did not show an impact of P4P on outcome measures. Furthermore, P4P did not result in better quality of care, compared with the German hospital-based reimbursement scheme. CONCLUSION This study did not show any positive long-term effects of the implementation of P4P on quality of care. Therefore, our results do not support the hypothesis that P4P leads to significant improvements in quality of care.
