The studies that led to those estimates were based on relatively small patient populations and employed variable diagnostic identifiers of ARDS. The purpose of this study was to estimate the incidence of ARDS and its mortality rate from a large database to which refined diagnostic criteria were applied. We conducted a retrospective review of all hospital discharges over a 4-year period using screening criteria designed to select patients with ARDS. Discharges from all acute care hospitals in the state of Maryland were reviewed using a computer database from the Health Services Cost Review Commission HSCRC . Patients 12 years of age were included. Screening criteria consisted of ICD-9 codes and cross-referenced with procedural codes for ventilatory support and . Data were normalized to the number of cases per 100 000 people. Results During the 4-year study period there were 2 501 147 hospitalizations. Applying the ICD-9 ARDS criteria yielded lower and upper limits of 159-205 439-568 531-694 and 529-720 cases of ARDS for 1992 1993 1994 and 1995 respectively. Normalizing for a population of 5 million yields yearly lower and upper limit rates of .
