Anti-psychotic Drug Prescribing Patterns Within Specialist Adult ID Services in England and Wales

Recruiting
Conditions
Intellectual Disability
Registration Number
NCT06238089
Lead Sponsor
University of Plymouth
Brief Summary

The overall aim of this observational study is to establish the anti-psychotic prescribing patterns across specialist intellectual disability (ID) services in England and Wales by collecting cross-sectional retrospective data at 7 annual time-points (1st July) from 2017 to 2023.

Detailed Description

Feasibility protocol objectives:

1. Is it feasible to identify People with Intellectual Disabilities (PwID) who have been prescribed 2 or more anti-psychotic medications over 7 years retrospectively.

2. It is possible to obtain a complete data set for each patient identified and therefore be able to explore the prescribing patterns across the eight sites.

3. Is it feasible to quantify anti-psychotic treatment (APT) prescribing in PwID as chlorpromazine equivalent dose values across different healthcare Trusts in England and Wales.

Main objectives:

4. To explore yearly and overall prescribing patterns among PwID (with or without mental-health reasons (psychiatric co-morbidities)) in receipt of ≥2 forms of anti-psychotic treatment (multiple) over time?

5. How has multiple anti-psychotic treatment prescribing changed between 2017 and 2023 using chlorpromazine equivalent dose values, in PwID with mental health and no mental health indications?

6. What has been the impact of the COVID-19 pandemic (and corresponding lockdown restrictions in England and Wales) on multiple anti-psychotic treatment prescribing among PwID?

7. Can the NHS England Statistical Process Control tool (SPC) be utilised to track yearly anti-psychotic treatment prescribing among PwID receiving multiple forms of anti-psychotic treatment, and monitor variation between services (sites) and patient groups (e.g. psychiatric co-morbidities; challenging behaviour).

SPC will be used to compare trends in multiple APT prescribing within/across participating healthcare trusts and utilised to track yearly oral/depots anti-psychotic treatment prescribing and monitor variation between services & patient groups.2017-2023

Main objective: Can the SPC be utilised to track yearly anti-psychotic treatment prescribing among PwID receiving multiple forms of anti-psychotic treatment, and monitor variation between services (sites) and patient groups (e.g. psychiatric co-morbidities; challenging behaviour)?

The differences in chlorpromazine equivalent dose values in PwID prescribed multiple anti-psychotic treatment across the 7-annual timepoints and across the 8 sites.2017-2023

Main objective: To explore yearly and overall prescribing patterns among PwID (with or without mental-health reasons (psychiatric co-morbidities)) in receipt of ≥2 forms of anti-psychotic treatment (multiple) over time.

The differences in chlorpromazine equivalent dose values in PwID prescribed multiple anti-psychotic treatment, with mental health indications, compared to those with no mental health indications between 2017 and 2023.2017-2023

Main objective: How has multiple anti-psychotic treatment prescribing changed between 2017 and 2023 using chlorpromazine equivalent dose values, in PwID with mental health and no mental health indications?

The differences in chlorpromazine equivalent dose values in PwID prescribed multiple anti-psychotic treatment before, during and after the COVID-19 pandemic.2017-2023

Main objective: What has been the impact of the COVID-19 pandemic (and corresponding lockdown restrictions in England and Wales) on multiple anti-psychotic treatment prescribing among PwID?
