Financial Incentives for Doctors Improves Patient Care by 7%

A recent study published in the Journal of Health Economics has found that aligning financial incentives between patients and healthcare providers through performance pay significantly enhances the quality of care provided by primary care physicians. The study, which involved an experimental approach, revealed that performance pay, whether high or low, resulted in similar improvements in healthcare quality, suggesting that even modest bonuses can effectively boost physician performance.

The study was conducted by J. Brosig-Koch and colleagues and employed a controlled experimental design involving primary care physicians. Participants were divided into two groups, each experiencing different pay structures. The first group worked under a traditional capitation payment system, where physicians receive a set amount per patient regardless of the number of services provided. The second group worked under a capitation plus performance pay system, which included bonuses of either 5% or 20% based on the quality of care provided.

Researchers collected data from three sources: behavioural data from the controlled experiment, administrative data from physicians’ practices, and self-reported survey data. This comprehensive approach allowed for a thorough analysis of physician behaviour and the impact of financial incentives on their performance.

The findings indicate that performance pay significantly enhances the quality of care provided by primary care physicians compared to capitation alone. Under the performance pay system, the quality of care increased by 5 percentage points with a 5% bonus and by 7 percentage points with a 20% bonus. Interestingly, the size of the bonus did not significantly impact the level of improvement, suggesting that even modest financial incentives can be effective.

The study also found that the introduction of performance pay reduced the variation in care quality among patients with different severities of illness. This indicates that performance pay can help ensure more consistent care across patient groups, addressing issues of undertreatment in more severe cases​​.

An essential aspect of the study was understanding what drives physicians’ responses to financial incentives. The researchers discovered that physicians’ altruism and their primary motivation for patient benefit were significant factors. Physicians who viewed their primary role as benefitting the patient provided higher quality care than those motivated by their own profit. Furthermore, physicians who were more risk-averse on behalf of their patients, compared to themselves, also delivered higher quality care.

“A plausible interpretation of this finding is that physicians with a more optimistic view on helpfulness and selflessness provide higher-quality treatment. The same goes for physicians with their patients’ health as the primary goal, regardless of any financial incentives,” says Professor Daniel Wiesen, one of the authors of the study.

The study’s behavioural data revealed that physicians adjusted their care quality based on the severity of the patient’s illness. This adjustment was more pronounced under the performance pay system, where high-severity patients benefitted the most from improved care. This suggests that performance pay can effectively mitigate the undertreatment of severely ill patients often observed under capitation systems​​.

These findings have significant implications for healthcare policy, particularly regarding the design of physician compensation schemes. The study suggests that integrating performance pay into existing capitation systems can improve healthcare quality without necessarily increasing overall costs. By incentivising higher quality care, performance pay can help address disparities in treatment and ensure that patients receive the appropriate level of care based on their needs​​.

The researchers noted that while the results are promising, further studies with larger samples are needed to confirm these findings and explore the long-term impact of performance pay on healthcare outcomes. They also highlighted the importance of considering physician attitudes and motivations when designing and implementing performance pay systems, as these factors significantly influence the effectiveness of such schemes​​.
