Social deprivation and the outcomes of crisis resolution and home treatment for people with mental health problems: a historical cohort study

Abstract

The development of crisis resolution and home treatment (CRHT) teams has been central to the UK Government's objective of reducing reliance on hospital-based care and is supported by a growing body of evidence. However, there has been no research specifically exploring the relationship between social deprivation and CRHT teams, in spite of evidence of an association between social deprivation and increased pressure on inpatient services. This article reports a study which tested the hypothesis that social deprivation is associated with the outcome of CRHT interventions. Using a historical cohort study design, we examined a total of 260 accepted referrals to a CRHT. Social deprivation was measured by the Index of Multiple Deprivation (Office of the Deputy Prime Minister 2004) as a predictor of CRHT interventions outcomes. CRHT outcomes were dichotomised into successful and unsuccessful and were defined with reference to the CRHT operational policy. Univariate analysis found that people who lived in more socially deprived areas had a poorer outcome, as did older people and those referred from the enhanced community mental health team (CMHT). Logistic regression analysis found that age and referral source were independently associated with outcome. Analysis of the demographic data also suggested a non-significant trend towards men having less successful outcomes. Further analysis exploring the characteristics of the different referral sources to the CRHT found that those referred from the enhanced CMHT were significantly more likely to be from the most deprived area. This suggested a relationship between an enhanced level of mental health need, social deprivation and poor outcome of CRHT intervention.
