The Patient Safety Indicators (PSIs) Composite (PSI 90) of the Agency for Healthcare Research and Quality has been found to have low positive predictive values. Because scores can affect hospital reimbursement and ranking, our institution designed a review process to ensure accurate data and incur minimal penalties under the Hospital Value-Based Purchasing Program.A multidisciplinary team was assembled to review PSI 90 within a performance period. The positive predictive value of each PSI was calculated. Weight-adjusted PSI rates were used to recalculate the PSI 90 Performance Period Index Value (PPIV). The adjusted PPIV was used to estimate what the achievement points and financial impact would have been if PSI review had not been implemented. Differences in PPIV, achievement points, and financial impact before and after PSI review were calculated.A total of 1,470 cases were flagged for PSI over a 2-year period. The positive predictive value was 63.3%. Refuting 36.7% of PSIs resulted in a decrease in the PPIV from 0.696 to 0.508, an increase in achievement points from 5 to 10, resulting in a decreased net loss of $111,773.Multidisciplinary review processes are practical and effective in identifying false-positive patient safety events. The real-time process affects hospital performance and resultant Medicare reimbursement substantially.
