Determinants of treatment disengagement among those at risk of suicide referred to primary mental health care services in Western Sydney, Australia

OBJECTIVE

Continued engagement with primary mental health services has been associated with the prevention of subsequent suicidal behaviour; however, there are few studies that identify determinants of treatment disengagement among those at risk of suicide in primary care settings. This study investigated determinants of treatment disengagement of those at risk of suicide who were referred to primary mental health care services in Western Sydney, Australia.

METHOD

This study used routinely collected data of those referred for suicide prevention services provided through primary mental health care services between July 2012 and June 2018. Associations between sociodemographic, diagnostic, referral- and service-level factors and treatment non-attendance and early treatment cessation were investigated using a series of multivariable generalised estimation equations.

RESULTS

There were 1654 suicidal referrals for 1444 people during the study period. Those identified with a risk of suicide were less likely to never attend treatments (16.14% vs 19.77%), but were more likely to disengage earlier from subsequent service sessions (16.02% vs 12.41%), compared to those with no risk of suicide. A higher likelihood of non-attendance to any primary mental health care service sessions was associated with those aged 25-44, lower socioeconomic status, a presentation for substance use and a referral from acute care (either emergency department or hospital). Among those who attended an initial treatment session, younger age (18-24 years) and a longer waiting time for an initial follow-up appointment were associated with a higher likelihood of early treatment cessation from primary mental health care services.

CONCLUSION

These findings can inform potential strategies in routine primary mental health care practice to improve treatment engagement among those at risk of suicidal behaviour. Youth-specific interventions, behavioural engagement strategies and prompt access to services are policy and service priorities.

Determinants of treatment non-attendance among those referred to primary mental health care services in Western Sydney, Australia: a retrospective cohort study

OBJECTIVES

Recommendations of the recent mental health reforms provided an opportunity to implement regional approaches to service provision through Primary Health Networks. This study is designed to identify the determinants of sociodemographic, diagnostic and referral-level factors and first treatment session non-attendance among those referred to primary mental health care (PMHC) services in Western Sydney, Australia.

DESIGN

This study used routinely collected retrospective PMHC data between July 2016 and December 2018.

SETTING

The study was based on a geographical catchment that covers four local government areas of Blacktown, Parramatta, Cumberland and Hills Shire in Western Sydney, Australia.

PARTICIPANTS

All individuals 5 years of age or older referred to PMHC services.

PRIMARY OUTCOME MEASURE

First treatment session non-attendance, following a referral to receive psychological treatments.

RESULTS

There were 9158 referrals received for 8031 clients, with 1769 (19.32%) referrals resulting in non-attendance to the first treatment session. Those with younger age (ORs ranging from 1.63 to 1.92), substance use (OR=1.55, 95% CI 1.17 to 2.06), poor English proficiency (OR=1.64, 95% CI 1.23 to 2.20), lower socioeconomic status (OR=1.57, 95% CI 1.34 to 1.83), psychotropic medication use (OR=1.20, 95% CI 1.06 to 1.36), and a referral by a social worker (OR=2.04, 95% CI 1.36 to 3.05), allied health (OR=1.49, 95% CI 1.03 to 2.16) or other professional (OR=1.72, 95% CI 1.30 to 2.29) were associated with a higher likelihood of first treatment session non-attendance. Those with a risk of suicide, who mainly speak a language other than English, and a previous use of PMHC services were more likely to attend their first treatment session.

CONCLUSION

Youth-specific treatment approaches, behavioural engagement strategies, facilitation of transport services for those live in deprived regions and improvements in capacity for mental health training among allied health professionals are areas of focus for primary care service and policy responses.
