Readmission after discharge from a medium secure service between 1999 and 2017: A retrospective cohort study.

The proportion of medium security hospital patients who were readmitted within 2 years of discharge aligns with estimates found in earlier national research using the same follow-up period. Since levels of inpatient progress bore little if any relationship to longer term outcomes, our findings highlight the need for investigating factors in the discharge environment that are linked to readmission. It is possible that readmission may indicate effective monitoring and responsive care to the changing needs of patients, but a better understanding of this is essential.
