Rate and predictors of disengagement from a 2-year early intervention program for psychosis in Hong Kong

Short-term disengagement from early intervention service for first-episode psychosis: findings from the "Parma Early Psychosis" program

PURPOSE

Service disengagement is a major concern for "Early Intervention in Psychosis" (EIP). Indeed, identifying predictors of engagement is crucial to maximize mental healthcare interventions in first-episode psychosis (FEP). No Italian study on this topic has been reported to date. Thus, the aims of this investigation were: (1) to examine short-term disengagement rate in an Italian population of FEP patients treated within an EIP service across a 1-year follow-up period, and (b) to assess the most relevant predictors of disengagement in the first year of treatment.

METHODS

All participants were young FEP help-seeking patients, aged 12-35 years, enrolled within the "Parma Early Psychosis" (Pr-EP) protocol. At baseline, they completed the Positive And Negative Syndrome Scale (PANSS), the Health of the Nation Outcome Scale (HoNOS) and the Global Assessment of Functioning (GAF) scale. Univariate and multivariate Cox regression analyses were used.

RESULTS

496 FEP individuals were enrolled in this research. Across the follow-up, a 16.5% prevalence of short-term disengagement was found. Particularly robust predictors of service disengagement were poor baseline treatment non-adherence, living with parents and the presence of brief psychotic disorder or schizophreniform disorder at entry.

CONCLUSION

About 16% of FEP patients disengaged the Pr-EP program within the first year of treatment. A solution to reduce disengagement and/or to favor re-engagement of these subjects might be to remain on EIP program caseloads allowing the option for low-intensity support and monitoring, also via remote technology.

Rates and Predictors of Disengagement and Strength of Engagement for People With a First Episode of Psychosis Using Early Intervention Services: A Systematic Review of Predictors and Meta-analysis of Disengagement Rates

Disengagement is a problem in early intervention for psychosis services; identifying predictors is important to maximise mental-health care.

Aim

To establish the average disengagement rate, time to disengage, and predictors of disengagement or strength of engagement.

Methods

Papers were identified from 5 databases and citation searches; chosen if they reported dis/engagement in early intervention services, discarded if they didn't give a clear definition of disengagement. The studies were rated for quality and a systematic review identified predictors of engagement; meta-analysis established the average disengagement rate. Meta-regression evaluated associations between disengagement and year of study or length of follow up.

Results

26 papers were reviewed comprising over 6800 participants, meta-analysis of 15 eligible cohorts found that the average disengagement rate was 15.60% (95% confidence intervals 11.76%-20.45%), heterogeneity was considerable, important to note when reporting as a global average. Higher disengagement rates were associated with earlier studies and length of follow up; causal factors are unclear due to the lack of data and complex interaction between clinical and methodological issues. Robust predictors of disengagement were substance use, contact with the criminal justice system, medication non-adherence, and lower symptom severity.

Conclusions

Disengagement rates have declined although the cause is not clear partly due to methodological variation, we suggest a guide for defining disengagement. Underpinning reasons for disengagement could include people who struggle to engage (substance users), don't want to engage (medication non-adherence) or feel they don't need to engage (lower symptomology). Future research should focus on minority status, education/employment during treatment, and digital technologies.

Disengagement From Early Intervention Services for Psychosis: A Systematic Review

OBJECTIVE

Therapeutic benefits associated with early services for psychosis are influenced by the degree to which participants engage in treatment. The main objective of this review was to analyze rates of disengagement in early psychosis services and identify predictors of disengagement in these settings.

METHODS

A systematic search for studies published in the 1966-2019 period was conducted in PubMed, Google Scholar, EBSCO, Ovid, and Embase. The Observational Cohort and Cross-Sectional Studies scale was used to assess the methodological quality of reports identified in this search. A revised version of the behavioral model of health service use was employed to evaluate and understand predictors of disengagement (categorized as predisposing, enabling, and need factors) identified in the studies with the highest quality.

RESULTS

Twenty studies met the inclusion criteria. Disengagement rates (12% to 53%) and definitions of disengagement varied widely across these studies. Most did not find a compelling association between predisposing factors (e.g., age) and disengagement. Enabling factors, such as lack of family support and living alone, were consistently found to be related to increased disengagement across studies. Finally, need factors, such as lower medication adherence and higher drug misuse, were associated with higher risk for disengagement.

CONCLUSIONS

Enabling and need factors seemed to be the most predictive of disengagement from early psychosis services. Substantial between-study variation in identified predictors of disengagement may be addressed by developing and applying a consensus definition of disengagement in future research.

Predictors of study drop-out and service disengagement in patients at clinical high risk for psychosis

PURPOSE

Study drop-out during follow-up and service disengagement frequently occur in patients at clinical high risk for psychosis (CHR-P). However, little is known about their predictors. Therefore, we aimed to analyze the rate and reasons for drop-out and service disengagement in CHR-P patients and investigate their sociodemographic and clinical predictors.

METHODS

Data from 200 patients of the prospective Früherkennung von Psychosen (FePsy) study were analyzed with competing risks survival models, considering drop-out and transition to psychosis as competing events. To investigate whether symptoms changed immediately before drop-out, t tests were applied.

RESULTS

Thirty-six percent of patients dropped out within 5 years. Almost all drop-outs also disengaged from our service. Hence, study drop-out was used as a proxy for service disengagement. Patients with more severe baseline disorganized symptoms and a late inclusion into the study were significantly more likely to disengage. Immediately before disengagement, there was significant improvement in negative symptoms only.

CONCLUSION

A considerable proportion of CHR-P patients disengaged from our clinical study and service. Patients who were included during a later study period with more assessments disengaged more often, which might have been due to more frequent invitations to follow-up assessments and thereby increasing participation burden. Hence, our study provides a cautionary note on high-frequency follow-up assessments. Larger-scale studies evaluating predictors on multiple domains would help to further elucidate drop-out and disengagement.

Parental Factors for Mental Health Service Engagement Among Chinese Young Adults

Mental health service disengagement can have devastating consequences for people in need of mental health services. This study explored parental factors in mental health service engagement among Chinese young adult mental health service users. Seventy-two Chinese young adults, aged from 18 to 26 years, were recruited from a Hong Kong community mental health service center. Nearly three-fifths (58.3%) of participants were female and over two-fifths (44.2%) attended college. Results of logistic regression analysis showed that Chinese young adult mental health service users with high levels of perceived need for services and low levels of perceived parental involvement in mental health services were more likely to engage in mental health services. However, concerns about the parent-child relationship, perceived parental encouragement and perceived parental demand for mental health service use were not associated with mental health service engagement. The practice implications of these results are discussed in light of the Chinese context.

Defining disengagement from mental health services for individuals experiencing first episode psychosis: a systematic review

BACKGROUND

Individuals affected by psychotic disorders frequently disengage from mental health services, although reports of this rate in the literature have ranged from 6 to 60%. One of the potential explanations for the large variation is that studies have adopted different definitions. Without a universal definition it is challenging to compare rates and factors leading to disengagement across studies. This systematic review aims to identify and compare how disengagement from psychosis services has been defined, measured and operationalised in the literature to date.

METHODS

A systemic literature search of the PubMed, PsycINFO and CINAHL databases was completed following the PRISMA guidelines for systematic reviews.

RESULTS

1506 Studies were identified, of which 30 were eligible to be included. It was found that disengagement was operationalized as either a categorical or continuous variable across studies, with 18 studies classifying it as a categorical, binary variable. Only four studies applied a time period over which disengagement was said to occur, and only four studies used an instrument to measure or predict disengagement. Few studies considered similar factors in their definition, when this occurred it was because the papers came from the same research group.

DISCUSSION

To truly understand the phenomenon of disengagement, studies need to have a comparable outcome variable. The need for consensus on a gold standard definition of disengagement that considers the full breadth of its complexity remains. A potential process for establishing a definition that includes set parameters, agreed upon terminology and time periods of assessment is discussed.

The rates and determinants of disengagement and subsequent re-engagement in young people with first-episode psychosis

BACKGROUND

A core component of treatment provided by early intervention for psychosis (EI) services is ensuring individuals remain successfully engaged with the service. This ensures they can receive the care they may need at this critical early stage of illness. Unfortunately, rates of disengagement are high in individuals with a first episode of psychosis (FEP), representing a major barrier to effective treatment. This study aimed to ascertain the rates and determinants of disengagement and subsequent re-engagement of young people with FEP in a well-established EI service in Melbourne, Australia.

METHOD

This cohort study involved all young people, aged 15-24, who presented to the Early Psychosis Prevention and Intervention Centre (EPPIC) service with FEP between 1st January 2011 and 1st September 2014. Data were collected retrospectively from clinical files and electronic records. Cox regression analysis was used to identify determinants of disengagement and re-engagement.

RESULTS

A total of 707 young people presented with FEP during the study period, of which complete data were available for 700. Over half of the cohort (56.3%, N = 394) disengaged at least once during their treatment period, however, the majority of these individuals (85.5%, N = 337) subsequently re-engaged following the initial episode of disengagement. Of those who disengaged from the service, 54 never re-engaged, representing 7.6% of the total cohort. Not being in employment, education or training, not having a family history of psychosis in second degree relatives and using cannabis were found to be significant predictors of disengagement. No significant predictors of re-engagement were identified.

CONCLUSION

In this study, the rate of disengagement in young people with first-episode psychosis was higher than found previously. Encouragingly, rates of re-engagement were also high. The concept of disengagement from services might be more complex than previously thought with individuals disengaging and re-engaging a number of times during their episode of care. What prompts individuals to re-engage with services needs to be better understood.

The association between community and service level factors and rates of disengagement in individuals with first episode psychosis

INTRODUCTION

Individuals who experience a first episode of psychosis require early intervention and regular follow-up in order to improve their prognosis and avoid long-term negative outcomes. However, approximately 30% of individuals accessing support will end up disengaging from early intervention (EI) services. Although we know that individual factors can impact rates of disengagement, less is known about potential service and community level factors.

METHODS

Data were gathered from a cohort of individuals attending a specialist youth mental health service in Melbourne, Australia between 1st January 2011 and 7th September 2014. Data were collected from clinical files and electronic medical records using a standardised audit instrument. Cox regression analysis was used to identify whether community level factors were predictors of disengagement.

RESULTS

Data were available for 707 young people experiencing a first episode of psychosis. Individuals residing in neighbourhoods of higher social deprivation were at a higher relative risk of disengaging, with 4.7% increase in engagement for each increase in decile of deprivation. The introduction of a new clinic was not significantly associated with a difference in the proportion of individuals disengaging from the service and distance to service was not significantly associated with disengagement rates.

DISCUSSION

Developing strategies focused on engaging young people with first episode psychosis who reside in more deprived areas may address the higher rates of disengagement these individuals experience. These finding suggest that location may not be a barrier to engagement, however services should be resourced in-line with the population demographic in their specific location.

Rates and predictors of disengagement of patients with first-episode psychosis from the early intervention service for sychosis service (EASY) covering 15 to 64 years of age in Hong Kong

AIM

This study aims at assessing the rate and predictors of disengagement of patients with first-episode psychosis (FEP) from the early intervention (EI) service in Hong Kong (EASY) that covers age 15 to 64.

METHODS

All FEP patients aged 15 to 64 years who were newly registered with the EASY programme of Kowloon West Psychiatric Unit from January to December 2012 were included. Data on socio-demographic, clinical characteristics and disengagement over 3 years of the EI service were obtained retrospectively through systematic clinical record review. Predictors of 3 different types of disengagement and their rate of occurrence were identified: complete disengagement (type I), disengaged and re-engaged through hospitalization (type II) and re-engaged as outpatient (type III).

RESULTS

Among the 277 patients included for analysis, 36 patients (13%) had type I disengagement, 17.2% (N = 21) were of age 15 to 25 and 9.7% (N = 15) were of age 25 to 64. Type II and type III disengagements were 4.3% and 13.4%, respectively. Early-stage poor drug compliance significantly predicted type I and type II disengagements. History of substance use, suicidal attempts and poor drug compliance predicted type III disengagement. Younger patients had significant earlier disengagement (χ²  = 5.01, df = 1, P = .025).

CONCLUSION

Results of the current study highlighted the different patterns of disengagement for different age groups and the importance of identifying the high-risk group at early stage of the illness. With the expansion of EI service for wider age group, studies of the differential needs of patient with different ages would be important to guide the future service development.

Predictors of disengagement from Early Intervention in Psychosis services

BACKGROUND

The effectiveness of Early Intervention in Psychosis (EIP) services for individuals with a first episode of psychosis (FEP) could be thwarted by high rates of early disengagement.AimsTo investigate which factors predict disengagement with EIP services.

METHOD

Using data from a naturalistic cohort of 786 EIP clients in East Anglia (UK), we investigated the association between sociodemographic and clinical predictors and disengagement using univariable and multivariable Cox proportional hazards models.

RESULTS

Over half (54.3%) of our sample were discharged before receiving 3 years of EIP care, with 92 (11.7%) participants discharged due to disengagement. Milder negative symptoms, more severe hallucinations, not receiving an FEP diagnosis, polysubstance use and being employed were associated with greater disengagement.

CONCLUSIONS

Our findings highlight heterogeneous reasons for disengagement with EIP services. For some patients, early disengagement may hinder efforts to sustain positive long-term EIP outcomes. Efforts to identify true FEP cases and target patients with substance use problems and more severe positive symptoms may increase engagement.Declaration of interestNone.

Patterns and predictors of trajectories for social and occupational functioning in patients presenting with first-episode non-affective psychosis: A three-year follow-up study

BACKGROUND

Functional impairment is prevalent in patients with first-episode psychosis (FEP). Longitudinal course of functioning in the early stage of psychotic illness is under-studied. In this report, we aimed to investigate the patterns and baseline predictors of social-occupational functional trajectories over 3 years, utilizing growth mixture modeling (GMM) analysis, in a large representative Chinese young FEP cohort in Hong Kong.

METHOD

Six hundred seventeen consecutive patients aged 15-25 years presenting with first-episode non-affective psychosis to a specialized early intervention service were studied. Data on demographic, pre-treatment and baseline clinical characteristics were collected. Individual class membership of functioning derived from GMM was based on ratings on Social and Occupational Functioning Scale (SOFAS) measured at five different time-points (baseline, 6, 12, 24 and 36 months) across 3-year follow-up.

RESULTS

Four distinct functional trajectories were identified including persistently poor (48.1%, n = 320), early improved (31.3%, n = 203), gradually improved (14.8%, n = 69) and improved-deteriorated (5.8%, n = 25) trajectories. Multinomial regression analysis revealed that male gender, lower educational attainment, a diagnosis of schizophrenia-spectrum disorder and a receipt of inpatient treatment upon initial presentation independently predicted persistently poor trajectory membership.

CONCLUSION

The current study reveals a heterogeneous course of social-occupational functioning in FEP. Our finding that approximately half of the patients displaying persistently poor trajectory over 3 years indicates functional impairment as an unmet therapeutic need in early illness phase. Further research applying individual-based trajectory analysis in FEP is warranted to facilitate better characterization of longitudinal patterns of functioning and development of targeted intervention to promote early recovery.

Association of an Early Intervention Service for Psychosis With Suicide Rate Among Patients With First-Episode Schizophrenia-Spectrum Disorders

IMPORTANCE

Patients with schizophrenia have a substantially higher suicide rate than the general public. Early intervention (EI) services improve short-term outcomes. However, little is known about the association of EI with suicide reduction in the long term.

OBJECTIVE

To examine the association of a 2-year EI service with suicide reduction in patients with first-episode schizophrenia-spectrum (FES) disorders during 12 years and the risk factors for early and late suicide.

DESIGN, SETTING, AND PARTICIPANTS

This historical control study compared 617 consecutive patients with FES who received the 2-year EI service in Hong Kong between July 1, 2001, and June 30, 2003, with 617 patients with FES who received standard care (SC) between July 1, 1998, and June 30, 2001, matched individually. Clinical information was systematically retrieved for the first 3 years of clinical care for both groups. The details of death were collected up to 12 years from presentation to the services. Data analysis was performed from October 30, 2016, to August 18, 2017.

MAIN OUTCOMES AND MEASURES

Suicide rate during 12 years was the primary measure. The association of the EI service with the suicide rates during years 1 through 3 and years 4 through 12 were explored separately.

RESULTS

The main analysis included 1234 patients, with 617 in each group (mean [SD] age at baseline, 21.2 [3.4] years in the EI group and 21.3 [3.4] years in the SC group; 318 male [51.5%] in the EI group and 322 [52.2%] in the SC group). The suicide rates were 7.5% in the SC group and 4.4% in the EI group (McNemar χ2 = 5.55, P = .02). Patients in the EI group had significantly better survival (propensity score-adjusted hazard ratio, 0.57; 95% CI, 0.36-0.91; P = .02), with the maximum association observed in the first 3 years. The number of suicide attempts was an indicator of early suicide (1-3 years). Premorbid occupational impairment, number of relapses, and poor adherence during the initial 3 years were indicators of late suicide (4-12 years).

CONCLUSIONS AND RELEVANCE

This study suggests that the EI service may be associated with reductions in the long-term suicide rate. Suicide at different stages of schizophrenia was associated with unique risk factors, highlighting the importance of a phase-specific service.
