A systematic review and meta-analysis of mental health service use in people who report psychotic experiences.

ABSTRACT:

Background

Self-reported psychotic experiences (PEs) are associated with psychopathology of all kinds, not just psychoses. However, systematic reviews on the relevance of this for health services are unavailable. Furthermore, whether association with service use is confounded by other psychopathology is unknown, and is relevant to prevention and treatment.

Objectives

Literature examining associations between PEs and service use was systematically reviewed. Study quality and the direction and extent of any associations were assessed, and meta-analysis conducted.

Methods

Systematic review and meta-analysis was carried out as per PRISMA guidelines. A search of electronic databases was performed based on free-text and structured terms. Included studies were evaluated by two raters using a structured tool and estimates extracted for reporting.

Results

Thirteen studies were returned. We found two prospective studies, and a minority of studies accounted for concurrent psychopathology, limiting our ability to test our main hypotheses. Five studies reported associations by different types of service use. Almost all studies assessed service use by self-report. Meta-analysis suggested that people who reported PEs were around twice as likely to report service use compared to those who did not (pooled OR for all included studies: 2.20,95% confidence intervals (95%CI): 1.66,2.91).

Conclusions

There was consistent evidence of association between PEs and mental health service use at the general population level. However, evidence for causation was poor due to a limited number of studies. Whether increased service use in this group is solely attributable to PEs, and therefore whether interventions aimed at limiting/preventing PEs might be effective, requires studies focusing on the relationships between PEs, psychopathology and service use.

Project description:BACKGROUND AND AIMS:Prior research has found bidirectional associations between psychotic experiences (PEs) and selected substance use disorders. We aimed to extend this research by examining the bidirectional association between PEs and various types of substance use (SU) and substance use disorders (SUDs), and the influence of antecedent mental disorders on these associations. DESIGN, SETTING, PARTICIPANTS AND MEASUREMENTS:We used data from the World Health Organization World Mental Health surveys. A total of 30 902 adult respondents across 18 countries were assessed for (a) six types of life-time PEs, (b) a range of types of SU and DSM-IV SUDs and (c) mental disorders using the Composite International Diagnostic Interview. Discrete-time survival analyses based on retrospective age-at-onset reports examined the bidirectional associations between PEs and SU/SUDs controlling for antecedent mental disorders. FINDINGS:After adjusting for demographics, comorbid SU/SUDs and antecedent mental disorders, those with prior alcohol use disorders [odds ratio (OR) = 1.6, 95% confidence interval (CI) = 1.2-2.0], extra-medical prescription drug use (OR = 1.5, 95% CI = 1.1-1.9), alcohol use (OR = 1.4, 95% CI = 1.1-1.7) and tobacco use (OR = 1.3, 95% CI = 1.0-1.8) had increased odds of subsequent first onset of PEs. In contrast, those with temporally prior PEs had increased odds of subsequent onset of tobacco use (OR = 1.5, 95% CI = 1.2-1.9), alcohol use (OR = 1.3, 95% CI = 1.1-1.6) or cannabis use (OR = 1.3, 95% CI = 1.0-1.5) as well as of all substance use disorders (ORs ranged between 1.4 and 1.5). There was a dose response relationship between both count and frequency of PEs and increased subsequent odds of selected SU/SUDs. CONCLUSIONS:Associations between psychotic experiences (PEs) and substance use/substance use disorders (SU/SUDs) are often bidirectional, but not all types of SU/SUDs are associated with PEs. These findings suggest that it is important to be aware of the presence of PEs within those with SUDs or at risk of SUDs, given the plausibility that they may each impact upon the other.

Project description:BackgroundIncorporating perspectives of health consumers, healthcare workers, policy makers and stakeholders through co-design is essential to design services that are fit for purpose. However, the experiences of co-design participants are poorly understood. The aim of this study is to explore the experiences and perceptions of people involved in the co-design of a new service for people with high healthcare service utilisation.MethodsA methodology informed by the principles of grounded theory was used in this qualitative study to evaluate the experiences and perceptions of co-design participants. Participants were healthcare professionals, health managers and leaders and health consumers involved in the co-design of the new service in Tasmania, Australia. Semi-structured interviews were conducted, and data were iteratively and concurrently collected and analysed using constant comparative analysis. Audio/audio-visual recordings of interviews were transcribed verbatim. Transcripts, memos, and an audit trail were coded for experiences and perspectives of participants.ResultsThere were thirteen participants (5 health professionals, 6 health managers and leaders, and 2 health consumers). Codes were collapsed into six sub-themes and six themes. Themes were bureaucracy hinders co-design, importance of consumers and diversity, importance of a common purpose, relationships are integral, participants expectations inform their co-design experience and learning from co-design.ConclusionMost participants reported positive aspects such as having a common purpose, valuing relationships, and having a personal motivation for participating in co-design. However, there were factors which hindered the adaptation of co-design principles and the co-design process. Our research highlights that bureaucracy can hinder co-design, that including people with lived experience is essential and the need to consider various types of diversity when assembling co-design teams. Future co-design projects could use these findings to improve the co-design experience for participants, and ultimately the outcome for communities.
