Effects of pay-for-performance on prescription of hypertension drugs among public and private primary care providers in Sweden

Abstract

This study exploits policy reforms in Swedish primary care to examine the effect of pay-for-performance (P4P) on compliance with hypertension drug guidelines among public and private health care providers. Using provider-level outcome data for 2005–2013 from the Swedish Prescription Register, providers in regions using P4P were compared to providers in other regions in a difference-in-differences analysis. The results indicate that P4P improved guideline compliance regarding prescription of angiotensin converting enzyme inhibitors and angiotensin receptor blockers. The effect was mainly driven by private providers, suggesting that policy makers should take ownership into account when designing incentives for health care providers.
