All Payer Inpatient Quality Indicators (IQI) by Hospital (SPARCS): 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 IQIs generated using methodology developed by Agency for Healthcare Research and Quality (AHRQ).
The IQIs are a set of measures that provide a perspective on hospital quality of care using hospital administrative data. These indicators reflect quality of care inside hospitals and include inpatient mortality for certain procedures and medical conditions; utilization of procedures for which there are questions of overuse, underuse, and misuse; and volume of procedures for which there is some evidence that a higher volume of procedures is associated with lower mortality.
All the IQI 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) IQI measures.

The mortality, volume and utilization measures IQIs are presented by hospital as rates or counts. Area-level utilization measures are presented by county as rates.

本数据集包含医院出院次数（分子、分母、总量计数）、观察值、期望值以及使用美国卫生研究与质量署（AHRQ）开发的方法计算得出的风险调整后的IQI指标，并附带相应的95%置信区间。这些IQI指标构成一套衡量工具，旨在通过医院行政数据对医院护理质量进行评估。这些指标反映了医院内部护理质量，包括特定手术和医疗状况的住院死亡率；对于存在过度使用、不足使用和误用疑问的手术的利用率；以及某些证据表明手术量增加与死亡率降低相关的手术量。所有IQI指标均使用自2009年开始的州级规划与研究合作系统（SPARCS）住院数据进行计算。AHRQ提供的美国人口普查数据文件被用于推导县级（区域级别）IQI指标的分母。死亡率、手术量和利用率指标以医院为单位以比率或计数形式呈现，而区域级别的利用率指标则以县为单位以比率形式呈现。
