The role of key workers in improving physical health in first episode psychosis: A scoping review

Perspectives of mental health clinicians on physical health of young people with early psychosis

The aim of this study is to explore the views and understanding of youth mental health clinicians with regard to the physical health of young people with early psychosis and their perspectives on lifestyle interventions improving the health and well-being of young people with early psychosis. Physical health disparities leading to premature mortality among people with mental illness are well evident in the literature. Mental health and physical health are directly correlated. The risk of poor physical health often begins before the onset of mental ill health. Young people with early psychosis are highly susceptible to poor physical health. A co-designed integrated approach focusing on early prevention and intervention in overall well-being and health is imminent for this targeted population to prevent poor physical health trajectory across the lifespan. Ten clinicians were recruited and participated in this study through semi-structured interviews. Five themes were identified: (i) Impact of early psychosis, (ii) Focus of care, (iii) Conversations around physical health, (iv) Co-location of specialist roles and (v) Health literacy. The findings of this study confirm the dimensional impact of early psychosis on the well-being and health of young people through the vicious cycle of early psychosis. Promotion of health literacy along with social connectedness and elements of self-determination, as well as having a prime focus on the individuals' experience in the journey of health promotion through participation in lifestyle interventions, has been identified as critically prominent.

Monthly engagement with EIP keyworkers was associated with a five-fold increase in the odds of engagement with psychosocial interventions

BACKGROUND

Early intervention in psychosis (EIP) supports people who are experiencing their first episode of psychosis (FEP). A new Model of Care (MoC) for EIP services was launched in Ireland in 2019. Three EIP demonstration sites were chosen to test this MoC through a 'hub and spoke' approach. These services were a new way of organising care for people experiencing FEP, based upon a recovery model of care, and which sought to standardise care, improve access by clinically led multidisciplinary teams. This included newly created EIP keyworker roles whereby keyworkers assumed responsibilities regarding assessment, comprehensive individual care planning and coordination of care.

METHODS

A mixed methods design utilising the UK Medical Research Council's process evaluation framework. Purposive sampling techniques were utilised. Descriptive analyses and logistic regression were performed to examine how increased keyworker engagement influenced the use of other psychosocial interventions within the EIP demonstration sites. Thematic analyses was used for qualitative data.

RESULTS

There was a strong positive relationship between keyworker contacts and psychosocial interventions offered. Specifically, the odds of achieving at least monthly engagement with cognitive behavioural therapy for psychosis (CBTp; (5.76 (2.43-13.64), p < 0.001), and behavioural family therapy (BFT; (5.52(1.63-18.69, p < 0.006)) increased by fivefold with each additional monthly keyworker contact. For individual placement support (IPS) each additional monthly keyworker contact was associated with a three-fold increase in the odds of achieving monthly attendance with IPS (3.73 (1.64-8.48), p < 0.002). Qualitative results found that the EIP keyworker role as viewed by both service users and staff as a valuable nodal point, with a particular emphasis on care coordination and effective communication.

CONCLUSIONS

This study advances the understanding of keyworker effects through qualitative evidence of keyworkers functioning as a "linchpin" to the service, while the positive response association between keyworker contacts and engagement with other services provides quantitative support for keyworkers reducing the organisational or structural barriers to service access. Given the importance of these positions, health systems should ensure that EIP programmes identify qualified and experienced staff to fill these roles, as well as allocate the appropriate funding and protected time to support keyworker engagement and impact.

Keyworker mediated enhancement of physical health in patients with first episode psychosis: A feasibility/acceptability study

AIM

Early intervention for people experiencing first episode psychosis is a priority, and keyworkers are vital to such services. However, keyworkers' roles in addressing first episode psychosis patients' physical health are under researched. This study addresses this knowledge gap by evaluating a keyworker-mediated intervention promoting physical health among first episode psychosis patients.

METHODS

The study was informed by the Medical Research Council's Framework for Complex Interventions to Improve Health. First episode psychosis participants were recruited from three Irish mental health services. The intervention was evaluated in terms of its feasibility/acceptability.

RESULTS

Feasibility outcomes were mixed (recruitment rate = 24/68 [35.3%]; retention rate = 18/24 [75%]). The baseline sample was predominantly male (M:F ratio = 13:6; Med age = 25 y; IQR = 23-42 y). Common health issues among participants included overweightness/obesity (n = 11) and substance use (smoking/alcohol consumption [n = 19]). Participants' initial health priorities included exercising more (n = 10), improving diet (n = 6), weight loss (n = 7) and using various health/healthcare services. The intervention's acceptability was evidenced by the appreciation participants had for physical health keyworkers' support, as well as the healthy lifestyle, which the intervention promoted. Acceptability was somewhat compromised by a low-recruitment rate, variable linkages between keyworkers and general practitioners (GPs) and COVID-19 restrictions.

CONCLUSIONS

Physical health-oriented keyworker interventions for first episode psychosis patients show promise and further evaluation of such initiatives is warranted. Future interventions should be mindful of participant recruitment challenges, strategies to enhance relationships between keyworkers and GPs, and if necessary, they should mitigate COVID-19 restrictions' impacts on care.
