Hospitalization trajectories for patients in the 4 hospitalization pattern clusters. For patients in each of the 4 identified hospitalization pattern clusters, their hospitalization status (either hospitalized (in blue) or not hospitalized (in grey)) for each of the 1095 days of observation (starting from the patient index admission) are illustrated. The figure presents inpatient service utilization for patients in each identified cluster on a time axis (from Day 0 (index admission) to Day 1095 (end of observation)). It highlights variations in hospitalization patterns across patients and clusters through contrasting-colored blocks for days when hospitalized or not for a primary psychiatric diagnosis
