Impact of an integrated medicines management service on preventable medicines-related readmission to hospital: a descriptive study.

Background: Medication contributes to 5-20% of hospital admissions, of which half are considered preventable. An integrated medicines management service (IMMS) was developed at a large general hospital in London to identify and manage patients at risk of a preventable medicines-related readmission (PMRR) to reduce the risk of PMRR.

Objective: To investigate the effect of the pharmacy IMMS on the rate of PMRR within 30 days of the first discharge.
