Three time periods were studied: 1) 1995/96 at the beginning of restricted access to atypical agents; 2) 1998 at the last year of restricted access; and 3) 2000 the second year of open access. Multivariable Cox proportional hazards and logistic regression models were used to identify risk factors influencing LOS and readmission within one year of discharge respectively. Retrospective administrative prescription claims provided data on the use of and expenditure for atypical agents before and after the policy change. -- Results: Total days hospitalization for schizophrenia in 1995/96 was 15,089, 16,318 in 1998 and 15,691 in 2000. There were 57 (18.2%) fewer patients admitted to hospital and 98 (16.7%) fewer admissions during the period of open access (2000) when compared to baseline (1995/96). However, median LOS in 2000 was significantly longer than in 1995/96 (22.0 vs. 15.0 days, P<0.001). Being admitted in 2000 compared to baseline was a significant predictor of increased LOS (HR: 3.04, CI=1.57-5.86, P=0.0009); independent of requiring ECT (HR: 2.49, CI=1.69-3.66, P<0/001); seclusion (HR: 1.87, CI=1.41-2.50, P<0.001); thought disorder (HR: 1.41, CI=1.11-1.81, P=0.006); suicidal ideation on admission (HR: 0.70, CI=0.57-0.86, P=0.0007) and discharging against medical advice (HR: 0.38; CI=0.27-0.54, P<0.001).
