ObjectiveTo determine whether providing private practitioners with triage criteria for their low-risk chest pain patients would safely enhance bed utilization efficiency in coronary and intermediate care units.DesignProspective, controlled, interventional trial using an alternate month study design.SettingA large teaching community hospital.PatientsCohort of 404 low-risk patients with chest pain for whom a diagnosis of myocardial infarction has been excluded and who have not sustained complications, required interventions, or developed unstable comorbidity.InterventionsDuring intervention months, private practitioners caring for low-risk patients in the coronary and intermediate care units were contacted 24 hours after admission. Physicians were informed that the transfer of low-risk patients to nonmonitored beds could probably be done safely, based on the results of a pilot study. The practitioner had the option of agreeing to or deferring patient transfer. During control months, physicians were not contacted in this way.Measurements And Main ResultsUse of the triage criteria by private practitioners reduced lengths of stay in the intermediate and coronary care units by 36% and 53%, respectively. Bed availability increased by 744 intermediate and 372 coronary care unit bed-days per year. Charges decreased by $2.6 million per year and profits improved by $390,000 per year. There were not significant differences in complications between control and intervention patients and in no case (95% CI, 0% to 1.6%) did the triage criteria adversely affect quality of care.ConclusionsThe early transfer triage criteria may be a safe and efficacious decision aid for improving bed utilization in intermediate and coronary care units. In addition, this study shows the feasibility of and potential benefits from applying practice guidelines at a community hospital.
