Figures

  Fig. 1. Summary of patients discharged and readmitted over three overlapping periods: 7-days, 30-days and 60-days postdischarge

  Fig. 2. Left panel: Number of planned and unplanned readmissions per 1000 live discharges, per day up to 30 days post-discharge. Right panel: Number of unplanned readmissions per 1000 live discharges, per day up to 30 days post-discharge to the same hospital, other hospitals within the same area health services (AHS) and other hospital in other AHS. Here readmission refers only to the first readmission after discharge. Subsequent readmissions by the same patient have been ignored

  Fig. 3. Distribution of selected features characterizing index admissions that are followed by unplanned readmission within 7 days from discharge or unplanned readmission between 8 and 30 days from discharge. Selected features are those for which the difference in proportions is statistically significant. LOS = Length of Stay; CumLOS=Cummulative LOS; ED = Emergency Department; Emergency/Mobile ward refers to Emergency ward or mobile acute treatment units
