Introduction

This site presents hospitalizations by selected diagnosis for Michigan residents hospitalized in all short-stay hospitals (including Veterans Administration hospitals, but excluding military hospitals) in Michigan, Ohio, Indiana and Wisconsin. These hospitalizations are from the Michigan Resident Inpatient files, 1998-2014, which accounted for approximately 1.25 million hospitalizations annually. Hospitalizations are inpatient hospital stays as measured by stays that were completed during the specified year. The number of hospitalizations is often greater than the number of persons hospitalized since some persons are hospitalized more than once during the year.

The principal diagnosis for each hospitalization was coded according to the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM). Annually, there were more than 6,500 different principal diagnoses recorded for Michigan patients. These detailed diagnoses were grouped into 42 diagnostic conditions which accounted for 79.3 percent of all hospitalizations. These conditions are selected for tabulations because of stated interest from staff in the public health field, are presented in the National Hospital Discharge Survey summaries, or are among the most frequent hospitalizations. They are grouped and coded to be comparable with those published in the National Hospital Discharge Survey: Annual Summary by the National Center for Health Statistics, U.S. Department of Health and Human Services.

To view detailed information for your community, select from the tables for leading diagnoses for your community for 2014 by age group or gender, trends for the leading diagnoses for 2009-2013 versus 2014 by age group, and detailed diagnoses for 1998-2014 by age group or gender. The community-level tables provide information on hospitalizations for Michigan's counties, local health departments, and the state.

We hope that you find this material useful.
