[BDSP. Notice produite par INIST Ddk7R0xM. Diffusion soumise à autorisation]. Context Evidence exists that high-volume hospitals (HVHs) have lower mortality rates than low-volume hospitals (LVHs) for certain conditions. However, few employers, health plans, or government programs have attempted to increase the number of patients referred to HVHs. Objectives To determine the difference in hospital mortality between HVHs and LVHs for conditions for which good quality data exist and to estimate how many deaths potentially would be avoided in California by referral to HVHs. Design, Setting, and Patients Literature in MEDLINE, Current Contents, and FirstSearch Social Abstracts databases from January 1,1983, to December 31,1998, was searched using the key words hospital, outcome, mortality, volume, risk, and quality. The highest-quality study assessing the mortality-volume relationship for each given condition was identified and used to calculate odds ratios (ORs) for in-hospital mortality for LVHs vs HVHs. These ORs were then applied to the 1997 California data : base of hospital discharges maintained by the California Office of Statewide Health Planning and Development to estimate potentially avoidable deaths. Main Outcome Measures Deaths that potentially could be avoided if patients with conditions for which a mortality-volume relationship had been treated at an HVH vs LVH. Results The articles identified in the literature search were grouped by condition, and predetermined criteria were applied to choose the best article for each condition. (...)
