Methods and Limitations
Among hospital discharges to children and young people (aged 17 years or younger), we examined the distribution of first-listed diagnoses among discharges having diabetes as any listed diagnosis. We used data from the Kids’ Inpatient Database (KID), sponsored by the Agency for Healthcare Research and Quality (AHRQ). The 2009 KID contains information on a sample of hospital inpatient stays for children 20 years of age and younger from the following 44 states’ data organizations participating in the Healthcare Cost and Utilization Project: Arkansas Department of Health and Human Services; Arizona Department of Health Services; California Office of Statewide Health Planning and Development; Colorado Hospital Association; Connecticut—Chime, Inc.; Florida Agency for Health Care Administration; Georgia Hospital Association; Hawaii Health Information Corporation; Iowa Hospital Association; Illinois Department of Public Health; Indiana Hospital Association; Kansas Hospital Association; Kentucky Cabinet for Health and Family Services; Louisiana Department of Health and Hospitals; Massachusetts Division of Health Care Finance and Policy; Maryland Health Services Cost Review Commission; Maine Health Data Organization; Michigan Health and Hospital Association; Minnesota Hospital Association; Missouri Hospital Industry Data Institute; MHA—An Association of Montana Health Care Providers; North Carolina Department of Health and Human Services; Nebraska Hospital Association; New Hampshire Department of Health and Human Services; New Mexico Health Policy Commission; New Jersey Department of Health and Senior Services; Nevada Department of Health and Human Services; New York State Department of Health; Ohio Hospital Association; Oklahoma State Department of Health; Oregon Association of Hospitals and Health Systems; Pennsylvania Health Care Cost Containment Council; Rhode Island Department of Health; South Carolina State Budget and Control Board; South Dakota Association of Healthcare Organizations; Tennessee Hospital Association; Texas Department of State Health Services; Utah Department of Health; Virginia Health Information; Vermont Association of Hospitals and Health Systems; Washington State Department of Health; Wisconsin Department of Health and Family Services; West Virginia Health Care Authority; Wyoming Hospital Association. The 2009 KID includes about 3.4 million pediatric discharges from more than 4,121 U.S. community, non-rehabilitation hospitals. Discharge weights are provided to calculate national estimates. A more detailed description of the KID is available.1
Among discharges to children and young people having diabetes (ICD-9-CM code 250) as any listed diagnosis, the first-listed diagnosis was grouped by disease system following Classification of Diseases and Injuries of ICD-9-CM.
Hospitalizations involving persons with diabetes are underestimated because long-term hospitals and federal hospitals are not included in the KID sample. Because KID samples hospital discharges, the proportion for each category reflects the proportion of discharges, not the proportion of people.
