  1. Note: Data include all treat-and-release discharges at emergency departments during 2008 in Arizona, Massachusetts, and Utah.
  2. * Duration is measured in minutes as the difference between admission and discharge time for each visit.
  3. ** Disease categories are based on Clinical Classification Software, which is a diagnosis and procedure categorization scheme based on the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM).The HCUP SEDD do not differentiate between the primary diagnosis codes and other diagnosis codes. Therefore, we used all diagnosis codes reported for each visit when creating broader CCS disease categories. CCS disease codes: [1-10] infectious and parasitic diseases; [11-47] neoplasm; [48-58] endocr, nutri, metab, immun diseases; [59-64] diseases of blood, blood forming organs; [65-75] mental disorders; [76-95] diseases of nervous systems and sense organs; [96-121] diseases of circulatory systems; [122-134] diseases of respiratory systems; [135-155] diseases of digestive systems; [156-175] diseases of genitourinary systems; [176-196] complications of birth, pregnancy, puerperium; [197-200] diseases of skin and subcutaneous tissue; [201-212] diseases of musculoskel, connective tissue; [213-217] congenital anomalies; [218-224] perinatal conditions; [225-244] injury and poisoning; [245-259] other conditions.
