Underutilization of acute care settings in a tertiary care hospital.
OBJECTIVE: To estimate underutilization of acute care settings in a tertiary care hospital. DESIGN: A retrospective and concurrent cohort study using chart reviews and the Intensity of service, Severity of illness, Discharge screen for Acute Care (ISD-AC(R)) tool to measure appropriateness of acute care for patients who were receiving care in a less acute setting, as an indicator of underutilization. SETTING: A 450-bed tertiary care teaching hospital. STUDY PARTICIPANTS: Patients discharged from the emergency department, patients discharged from acute care inpatient units and patients in acute, non-critical care settings. INTERVENTIONS: None. MAIN OUTCOME MEASURES: The percentage of patients discharged from the emergency department who did not meet the criteria for acute care discharge screens; the percentage of patients discharged from an acute care inpatient unit who did not meet the criteria for discharge screens; and the percentage of patients who were in acute, non-critical care beds and who met the criteria for critical care. RESULTS: It was found that six out of 168 patients [3.57%; 95% confidence interval (CI), 1.32-7.61%] did not meet the discharge screens at the time of discharge from the emergency department. Four out of 156 patients (2.56%; 95% CI, 0.70-6.43%) did not meet the discharge screens at the time of discharge from an acute care inpatient service and two out of 156 acute care patients (1.33%; 95% CI, 0.02-4.73%) who were in non-critical care beds met the criteria for critical care. CONCLUSION: These findings of underutilization may help to quantitate an unmet need in health care.
