Provider feedback reports (PFRs) offer one way for providers to use their electronic health record (EHR) data to understand aspects of their clinical performance and improve quality of care. The Primary Care Information Project (PCIP) serves as a bureau of the New York City Department of Health and Mental Hygiene and as a Regional Extension Center that helps area healthcare providers adopt and achieve Meaningful Use of EHR systems. This study analyzes improvement on multiple quality measures pre- and post-receipt of a comprehensive, EHR-based PFR that PCIP created for its member providers. We analyzed improvement among low- versus high-performing providers pre- and post-receipt of the PFR. Pre-PFR receipt, improvement between high and low performers varied per measure. Post-PFR receipt, low performers improved more than high performers on all measures, and more than themselves in the pre-PFR period. Findings suggest PFRs derived directly from provider EHRs may particularly assist lower-performing providers to improve performance.
