OBJECTIVE

This article aims to examine the impact of clinical and demographic factors on both rapid readmission (being readmitted within 30 d) and frequent readmission (experiencing three or more admissions) in a London mental health trust.

METHODS

A four-year study period with a sample of 7648 inpatients were examined with chi-square or Mann-Whitney U tests, and binary logistic regressions to assess the associations and possible predictors of rapid (readmitted within 30 d) and frequent (admitted at least three times) readmission.

RESULTS

Frequent admitters were more likely to be unemployed, have more care-coordinators, be living in accommodation with support, be Black or Black British, and to have certain diagnoses. Binary logistic regression revealed that our variables of interest explained between 36.1 and 60.9% of the variation in number of readmissions (±3 admissions), and between 3.7 and 4.2% of the variation in time to readmission (±30 d).

CONCLUSIONS

Identifying factors that are associated with rehospitalisation and understanding their importance is necessary to reduce the risk of readmission. This study suggests that particular demographic, clinical and treatment factors require consideration to tackle the seemingly wide range of factors that could be affecting readmission to inpatient services.
