Hospital Inpatient Discharges (SPARCS De-Identified): Patient Safety Indicators (PSI) by Hospital: Calendar Year 2015

The datasets contain hospital discharges counts (numerators, denominators, volume counts), observed, expected and risk-adjusted rates with corresponding 95% confidence intervals for Patient Safety Indicators generated using methodology developed by Agency for Healthcare Research and Quality (AHRQ). The PSIs are a set of indicators providing information on potential in hospital complications and adverse events following surgeries, procedures, and childbirth. The PSIs were developed by AHRQ after a comprehensive literature review, analysis of ICD-9-CM codes, review by a clinician panel, implementation of risk adjustment, and empirical analyses. All PSI measures were calculated using Statewide Planning and Research Cooperative System (SPARCS) inpatient data beginning 2009. US Census data files provided by AHRQ were used to derive denominators for county level (area level) PSI measures. The mortality, volume and utilization measures PSIs are presented by hospital as rates or counts. Area-level measures are presented by county as rates.

本数据集包含基于美国医疗保健研究与质量局（Agency for Healthcare Research and Quality, AHRQ）开发的方法生成的患者安全指标（Patient Safety Indicators, PSIs）相关数据，具体包括医院出院数（分子、分母及总量计数）、观测率、预期率与风险调整后率，以及对应95%置信区间。患者安全指标（PSIs）是一类用于反映手术、操作及分娩后医院内潜在并发症与不良事件的监测指标。该指标体系由AHRQ经全面文献综述、ICD-9-CM编码分析、临床专家小组评审、风险调整方法的应用及实证分析后开发完成。所有PSI指标均基于2009年起的全州规划与研究合作系统（Statewide Planning and Research Cooperative System, SPARCS）住院患者数据计算得到。AHRQ提供的美国人口普查数据文件，被用于推导县级（区域级）PSI指标的分母数值。以医院为统计单元的PSI指标（涵盖死亡率、住院总量及住院使用率相关指标）以率值或计数形式呈现；区域级PSI指标则以县为统计单元，仅以率值形式发布。
