1. 1. To review the current level of compliance with CPFT (Cambridge & Peterborough Foundation Trust) guidelines by inpatients prescribed anti-psychotics at George Mackenzie House (GMH) low-secure unit and likewise, with NHFT (Northamptonshire Foundation Trust) guidelines by inmates prescribed anti-psychotics at HMP Whitemoor's Fens Unit.

2. 2. To identify any differences or similarities in compliance rates between both sites.

3. 3. To identify any possible areas of difficulty in ensuring full compliance with said guidelines and suggest possible solutions.

A retrospective design was used, in which the electronic and hardcopy patient records of service users at both sites, covering a specified time-frame (2nd Dec 2021- 2nd Dec 2022) were screened. Data collected from eligible users included demographic information, names of anti-psychotics used and results of each individual's screening profile measured against the respective Trust's guidelines.

The demographic profiles of eligible service users at both sites were largely similar.

17 out of 18 services users from GMH and 23 out of 50 service users from the Fens Unit were found eligible for the audit.

The majority of eligible service users at both sites (88-100%) were compliant with measurement of relevant laboratory markers, as per Trust guidelines.

However, at both sites, there were notable omissions in monitoring of certain physical parameters, especially waist circumference (100% omission in both sites) and ECG monitoring ( 60% omission in prison,14% in GMH), which is important given the significant comorbidity of cardiovascular risk factors amongst service users at both sites.

We noted disproportionate compliance in the monitoring of different physical health parameters. While laboratory tests were on the whole, satisfactorily monitored, there were gaps in other clinical measurements like waist circumference and ECG recordings. We postulate several reasons for this discrepancy, including:

• • A possible lack of awareness about the importance of measuring parameters like waist circumference, which also indicates a lack of familiarity with Trust guidelines.

• • A lack of time/inconvenience in ensuring adequate recording of clinical parameters

• • Inadequate reminders to conduct relevant physical health checks.

We suggest possible solutions to ensure 100% compliance: for example, creating a teaching session for staff and service users on pertinent topics, like metabolic syndrome or creating electronic aids to remind staff when physical measurements are due.

This audit also engendered further questions on appropriateness of anti-psychotic prescription and importance of educating service users about physical complications of anti-psychotic use. These could be the focus of future audits.
