Annual data from the New York State Department of Health details children's and adult utilization of health services within managed care plans. The dataset includes measures such as observed and expected rates, percentiles, and member counts for evaluating plan performance. Information collection began in 2009 and is part of the state's Quality Assurance Reporting Requirements (QARR) system.
Use Cases
- Analyze trends in service utilization rates by payer, plan, and age category over multiple measurement years.
- Compare observed rates against expected rates (O/E Ratio) to identify plans with statistically significant performance deviations.
- Benchmark individual plan performance using percentile columns (e.g., Percentile 10th, 50th, 90th) for specific measures.
- Assess the volume of services provided by examining the relationship between member months, events, and calculated rates.
Strengths
- Contains multiple performance metrics per record, including observed rate, expected rate, O/E ratio, and five percentile values.
- Data collection is annual and spans from at least 2009, enabling longitudinal analysis.
Limitations
- Plans with fewer than 30 eligible events are excluded from statistical calculations, potentially omitting data for smaller populations.
- The specific number of rows, total records, and overall dataset size are unknown.
