Asthma hospitalization data are extracted from Minnesota Hospital Discharge Data (MNHDD), which is maintained by the Minnesota Hospital Association (MHA). MHA represents Minnesota's hospitals and health systems. Hospitals submit inpatient discharge data to MHA using a standardized billing form. In 2021, 90% of all hospitals in the state reported hospital discharge data to the MHA. MHA began data-sharing agreements with several states in 2005. Emergency Department visits are defined as Minnesota residents receiving care at an emergency facility in Minnesota or North Dakota who are treated and released or subsequently admitted to the hospital.

          Source: Minnesota Hospital Association. Rates based on counts less than or equal to 20 should be interpreted with caution; the rate maybe unstable because it can change dramatically with the addition or subtraction of one case. To protect an individual's privacy, hospitalization counts under 5 are suppressed if the underlying population is less than or equal to 100,000.
