Incorporating harms into the weighting of the Revised AHRQ Patient Safety for Selected Indicators Composite (PSI 90).
Zrelak PA, Utter GH, McDonald KM, et al. Incorporating harms into the weighting of the revised Agency for Healthcare Research and Quality Patient Safety for Selected Indicators Composite (Patient Safety Indicator 90). Health Serv Res. 2022;57(3):654-667. doi:10.1111/1475-6773.13918.
The Agency for Healthcare Research and Quality (AHRQ) Patient Safety Indicators (PSIs) are widely used for measuring and reporting hospital quality and patient safety. This paper describes the process of reweighing the composite patient safety indicator (PSI 90) to incorporate excess harm reflecting patients’ preferences for various possible related outcomes (e.g., readmissions, reoperation, long-term care stay, death). Compared to the original frequency-based weighting, some component indicators in the reweighted composite – including postoperative respiratory failure, postoperative sepsis, and perioperative pulmonary embolism or deep vein thrombosis – contributed to the greatest harm.
