Medicaid Mental Health Readmission Rates by Region and Year

New York State tracks unplanned readmissions for Medicaid members with mental illness diagnoses to monitor its shift to managed care. The dataset contains annual and quarterly readmission rates at 30 and 90 days, grouped by region and coverage category. It is published by data.ny.gov and covers the period from 2014 through 2021.

Use Cases

• Analyze trends in the 'Rate' and 'YTD Rate' columns over 'Year' and 'Quarter' to assess the impact of managed care transition.
• Compare 'Numerator' and 'Denominator' values across different 'Region or Coverage Category' groupings to identify geographic disparities in readmission outcomes.
• Model the relationship between 'Grouping Description' (e.g., age groups, inpatient types) and readmission 'Rate' to identify high-risk patient cohorts.
• Use 'Metric ID' and 'Metric Description' to filter and study specific performance measures, such as 30-day versus 90-day readmissions.

Strengths

• Multi-year coverage from 2014 to 2021 provides a longitudinal view of policy impact.
• Data is structured with 14 distinct columns enabling analysis by region, year, quarter, and patient grouping.

Limitations

• The dataset lacks individual patient records, containing only aggregated percentages and counts.
• Sample size and underlying row count are unknown, making it difficult to assess statistical robustness.
