Rates of Preventable Hospitalizations (Age<18) for Selected Medical Conditions by County

The dataset currently contains hospitalization counts and rates, statewide and by county, for 4 conditions plus 3 composite measures. Hospitalizations for these conditions are potentially preventable through access to high-quality outpatient care. The conditions include: asthma (age 2-17), diabetes short-term complications (age 6-17), gastroenteritis (age 3 months-17 years), perforated appendix (retired, 2016), urinary tract infections (age 3 months-17 years), and low birth weight (<2500 grams; retired, 2016). The composite measures (age 6-17) include overall, acute conditions, and chronic conditions. The data provides a good starting point for assessing quality of health services in the community. The data does not measure hospital quality. Note: In 2015, HCAI only released the first three quarters of data due to a change in the reporting of diagnoses from ICD-9-CM to ICD-10-CM codes, effective October 1, 2015. Due to the significant differences resulting from the code change, the ICD-9-CM data is distinguished from the ICD-10-CM data in the data file beginning in 2016.

Additional Limitations

Rates based on only a small count of hospitalizations should be interpreted with caution. Blank rates in PDI #17-Perforated Appendix indicate that less than four appendicitis cases (denominator population) were treated. Users should exercise caution when comparing trends of rates over time that include partial year 2015 data (January-September 2015).

The 2005-2015Q3 data was compiled using PDI Software Version 5.0.2 (ICD-9-CM coding). The 2016-2022 data was compiled using PDI Software Version v2023 (ICD-10-CM coding). Due to methodology and coding differences in the two PDI software versions, trending over the different versions is not recommended.
