Distribution of patients according to discharge type and study year. Pie diagrams depicting the number of patients displaying RD (i.e., readmission during the immediate 30 days after discharge) according to discharge type (treating psychiatrists [TP] vs. a District Psychiatric Board [DPB]) in a 2000 and b 2010. The odds ratios (and corresponding significance) for readmission within 30 days among DBP-discharged vs. TP-discharged patients based upon logistic regressions are denoted. The significance of the difference between the odds ratios across the years (Pinteraction-ratio) is based upon a multiple logistic regression model
