Our aim was to improve service user satisfaction by increasing the interval between their depot injections where clinically feasible. By doing this, we aimed to reduce attendance at the South Kensington and Chelsea Community Mental Health Team (SK&C CMHT) depot clinic by 25% over a period of 3 months, improving the workload for nurses running the clinic.

Our first baseline measure was data gathered about service user satisfaction with their depot. Our second baseline measure was the average number of service users attending the depot clinic per week between May and November 2022. The balance measure was a medical review 3 months post-interval change to ensure there were no negative impacts from this change.

10 service users on 3-weekly anti-psychotic depots were identified. Our team devised criteria to select service users who were appropriate for our project. This included: a stable mental state, minimal side effects on the current dose, no breakthrough symptoms, good engagement with the depot clinic, and scope to increase the current dose. These service users were discussed with their care coordinator, consultant and depot clinic nurse. If the criteria were met, the dose and interval change was discussed with our pharmacist. Finally, service users were consented and their depot charts were amended.

The interval between depot injections for 2 service users was increased from 3 to 4 weeks on December 5th, 2022. The other 8 service users failed to meet the criteria set out in our methodology.

These 2 service users were asked to fill in a questionnaire on January 23rd, 2023. They reported that “it was not comfortable having an injection” and that “having it every 4 weeks was better” and “less hassle”. Their first medical review did not raise any safety concerns.

On average, 20 service users attend the SK&C CMHT depot clinic every week. There was no change in the average number of patients attending the depot clinic in the last two months as only 2 service users had their depot interval successfully altered.

Service users on depot injections can benefit from increasing the interval between their injections where clinically feasible. We would like to repeat this project for service users on 2-weekly depots and reassess if that makes an impact on satisfaction levels and attendance numbers at our depot clinic.
