# Ascertaining social worker contacts in routine mental healthcare and describing their distribution: a descriptive analysis of electronic records data from a large south London mental healthcare provider

## TL;DR

This study analyzes electronic health records to describe how mental health social workers interact with patients in London, highlighting patterns by age, gender, and diagnosis.

## Contribution

The study provides the first quantitative analysis of social worker contacts in mental healthcare using large-scale routine data.

## Key findings

- Most social worker contacts occurred in the 20–39 age group, among men, and in patients with schizophrenia.
- Males had more face-to-face contacts, while females were more likely to use phone or video contacts.
- Social worker contacts peaked between 2014 and 2015.

## Abstract

To describe the distribution of contacts with mental health service-employed social workers over time and by patient characteristics using routine mental health service data resources.

A descriptive study.

In a large secondary mental healthcare provider in London serving a geographic catchment of around 1.3 million residents, mental health social worker contacts were ascertained from the case note entries for all patients aged 16 years or above at the time of contact who received treatment in any services from 2008 to 2023.

Patient demographic and clinical characteristics at or closest to the social worker contact event.

A total 1 541 078 social worker contacts were extracted. Contacts were most likely in the 20–39 years age group (38.1%), in men (51.9%), in patients from white (45.3%) and black (38.8%) ethnic groups, in those who were non-cohabiting (89.9%) and in those living in more deprived neighbourhoods. The most likely diagnosis in those receiving social work contacts was schizophrenia (39.2%). Males had the highest number of face-to-face social worker contacts, and females were more represented in phone and video contacts. Over the past 16 years, social worker contacts were highest between 2014 and 2015.

To the best of our knowledge, this study is the first quantification of social work deployment within mental healthcare. Research into the role of social workers within mental health services has been of small scale and predominantly qualitative to date. However, growing data resources, building on distributions of service provision, present important opportunities for wider evaluation of the role of this professional group and the interventions they support within multidisciplinary teams.
