All Payer Patient Safety Indicators (PSI) Area Measures by Patient County: 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.

Upstream Metadata

NotesNotesSPARCS CY2009 through 2014 data were applied to PSI module and PDI module (for PSI17 only) of AHRQ version 4.5 to generate PSI measures at various levels as mentioned above. PSI module and PDI module (for PSI# 17 only) of AHRQ software version 4.5 were used to generate PSI measures with Present on Admission indicators used in calculations. County population estimates were provided by AHRQ and based on the US Census. To obtain the risk adjusted rates, the expected values were calculated using regression coefficients from risk adjustment models developed on the National sample.
