    Abstract:
    BACKGROUND: Some studies suggest intensive psychiatric consultation services facilitate medical care and reduce length of stay (LOS) in general hospitals. OBJECTIVE: To compare LOS between a consultation-as-usual model and a proactive consultation model involving review of all admissions, rapid consultation, and close follow-up. METHODS: LOS was compared in an ABA design between a 33-day intervention period and 10 similar control periods, 5 before and 5 after the intervention, on an internal medical unit. During the intervention period, a staff psychiatrist met with the medical team each weekday, reviewed all admissions, provided immediate consultation as needed, and followed all cases throughout their hospital stay. RESULTS: Time required for initial case review was brief, 2.9 ± 2.2 minutes per patient (mean ± S.D.). Over 50% of admissions had mental health needs: 20.3% were estimated to require specialist consultation to avoid potential delay of discharge. The consultation rate for the intervention sample was 22.6%, significantly greater than in the control sample, 10.7%. Mean LOS was significantly shorter in the intervention sample, 2.90 ± 2.12 versus 3.82 ± 3.30 days, and the fraction of cases with LOS > 4 days was significantly lower, 14.5% versus 27.9%. A rough cost benefit analysis was favorable with at least a 4.2 ratio of financial benefit to cost. CONCLUSIONS: Psychiatric review of all admissions is feasible, indicates a high incidence of mental health barriers to discharge, identifies more necessary consultations than typically requested, and results in earlier consultation. A proactive consultation model can reduce hospital LOS.
