A Systematic Review of the Predictors of Health Service Utilisation by Adults with Mental Disorders in the UK

Abstract

Objectives: To identify variables that predict health service utilisation (HSU) by adults with mental disorders in the UK, and to determine the evidence level for these predictors.Design: A narrative synthesis of peer-reviewed studies published after the year 2000. The search was conducted using four databases (ie, PsycINFO, CINAHL Plus with full text, MEDLINE and EMBASE) and completed on 25 March 2014. Setting:The majority of included studies were set in health services across primary, secondary, specialist and inpatient care. Some studies used data from household and postal surveys.Participants: Included were UK-based studies that predicted HSU by adults with mental disorders. Participants had a range of mental disorders including psychotic disorders, personality disorders, depression, anxiety disorders, eating disorders and dementia.Primary outcome: A wide range of HSU outcomes were examined, including general practitioner (GP) contacts, medication usage, psychiatrist contacts, psychotherapy attendances, inpatient days, accident and emergency admissions and 'total HSU'.Results: Taking into account study quality, 28 studies identified a range of variables with good preliminary evidence supporting their ability to predict HSU. Of these variables, comorbidity, personality disorder, age (heterogeneous age ranges), neurotic symptoms, female gender, a marital status of divorced, separated or widowed, non-white ethnicity, high previous HSU and activities of daily living, were associated with increased HSU. Moreover, good preliminary evidence was found for associations of accessing a primary care psychological treatment service and medication use with decreased HSU.

The treatment gap for mental disorders and associated factors in the Czech Republic

“…Globally, the overall treatment gap for mental disorders exceeds 50%, rising up to 90% in low and middle income countries [5]. Causes for the treatment gap are multi-faceted, and include affected individuals, clinicians and societal factors [6, 7]. Awareness of mental health symptoms and relating them to a potential mental health problem has been shown to be an important predictor of perceived need and help-seeking intentions in persons with untreated mental disorders [8].…”

Health service utilisation attributable to methamphetamine use in Australia: Patterns, predictors and national impact

“…Understanding the demand for health service utilisation related to methamphetamine is crucial for planning treatment programs and responding to additional demands on the health care system for both emergency and long term health care . Most research into health service use related to illicit drug use has focused on opioid use, injecting drug use and substance use generally .…”

Health and Social Care Diversity Among Individuals with Longstanding Physical and Psychological Health Problems: Pooled Repeated Cross Sectional Analyses

“…Prior research showed age, gender, ethnic, employment, and socio-economic differences in health and social care utilisation (Twomey et al 2015;Berthoud 2011). To control for the confounding effects of these variables on health and social care utilisation we included age (16-44 versus 45-64), gender, work status (not working/working), and ethnicity (white versus non-white) into the logistic regression model.…”
