Substance use amongst adult patients admitted to an irish acute mental health unit

Abstract

Introduction

Comorbid substance misuse in mental illness presents a significant challenge to mental health services. It may lead to higher rates of relapse, hospital admissions and poorer treatment outcomes. Up to 47% of inpatients in Irish mental health units may experience substance misuse. Despite the Irish government’s ‘Vision for Change’ policy (2006), access to specialised services remains variable.

Objectives

Evaluate: -prevalence of substance misuse at an Irish mental health unit. -quality and detail of the recorded substance misuse history. -access to specialised services for patients experiencing substance misuse.

Methods

A retrospective chart review of inpatients in a mental health unit over 12 months, was completed. Information recorded included: demographic details, diagnosis, substance use history; access to substance misuse services. Microsoft Excel was utilised for data input and analysis.

Results

267 patients were admitted over twelve months. Substance misuse was the primary diagnosis of 6% and the secondary diagnosis of 67%. 46% of patients reported current substance misuse, 52% reported historical substance misuse. Frequency and quantity of use was documented in 65% and 48% of cases respectively. 4% of patients with a substance misuse history were in current contact with addiction services.

Conclusions

Although 46% of patients reported substance misuse, only 4% were in contact with specialised addiction services. This highlights a significant unmet need. There was variability in the quality of the recorded substance misuse history. In order to fully understand comorbid substance misuse, this be addressed. The addition of a more formatted substance misuse section, to admission proformas, may help to alleviate this issue.
