Description:
The Medicare chronic condition prevalence index rating was created by following the CDC’s guidelines for creating estimates of high prevalence of multiple chronic diseases. Nineteen CMS Medicare chronic diseases were included: Alzheimer’s disease, arthritis, asthma, atrial fibrillation, autism spectrum disorder, cancer (excluding skin), COPD, depression, diabetes, heart disease, heart failure, hepatitis (chronic viral B & C), high cholesterol, hypertension (high blood pressure), HIV/AIDS, chronic kidney disease, osteoporosis, schizophrenia, and stroke. These county-level chronic disease prevalence estimates come from the CMS medicare chronic conditions data set. A composite score was calculated by ordering each disease estimate and assigning a score of 0 to counties in the bottom 25th percentile, 1 for counties in the middle (25th to 75th percentiles) or 2 to those in the top 25th percentile. These scores were summed so each county has a score range of 0-24. This data was then rated as “lowest” if it was in the bottom 25th percentile, “moderate” if in the middle percentile (25-75 percentile) and “highest” if in the top 25th percentile.
