Hospital Inpatient Quality Indicators for New York State

Hospital discharge counts and risk-adjusted rates for Inpatient Quality Indicators (IQIs) measure care quality inside hospitals. The Agency for Healthcare Research and Quality (AHRQ) methodology is applied to New York State SPARCS inpatient data beginning in 2009. Data includes observed, expected, and risk-adjusted rates with confidence intervals.

Use Cases

• Benchmark hospital performance by comparing 'IQI Value', 'Observed Rate', and 'Expected Rate' across 'Hospital Name' or 'Hospital Region'.
• Analyze geographic variation in care quality by aggregating 'IQI Value' or mortality rates by 'Hospital County'.
• Identify trends in procedure utilization or mortality over 'Year' for specific 'Composite Measure' or 'IQI Code' categories.
• Assess statistical reliability of quality measures using 'Lower 95CI' and 'Upper 95CI' columns for risk-adjusted rates.

Strengths

• Data spans from 2009 onward, providing a multi-year trend analysis.
• Includes 95% confidence intervals ('Lower 95CI', 'Upper 95CI') for statistical reliability assessment.
• Covers multiple IQI categories including mortality, volume, and utilization measures.

Limitations

• Sample size (row count) and total number of hospitals are unknown.
• Limited to New York State hospitals, which may not be nationally representative.
• Relies on administrative (SPARCS) data, which may have coding inaccuracies.
