The sharing of data is a core element of a learning health system. AHRQ has released the Network of Patient Safety Databases (NPSD) Chartbook 2023, which offers an overview of nonidentifiable, aggregated patient safety event and near-miss information, voluntarily reported by AHRQ-listed Patient Safety Organizations across the country between June 2014 and December 2022. The chartbook outlines the extent of harm reported, distribution of patient safety events, near misses, and unsafe conditions.
