Abstract
BACKGROUND: A substantial number of people experiencing self-harm or suicidal ideation present to hospital emergency departments (EDs). In 2014, a National Clinical Programme was introduced in EDs in Ireland to standardise care provision. Internationally, there has been limited research on the factors affecting the implementation of care for people who present with mental health crises in EDs. METHODS: This qualitative study examined factors influencing the implementation of the National Clinical Programme for Self-harm and Suicide-related Ideation in 15 hospitals in Ireland from early (2015-2017) through to later implementation (2019-2022). Semi-structured interviews were conducted with staff involved in programme delivery, with the topic guide and thematic analysis informed by the Consolidated Framework for Implementation Research. RESULTS: A total of 30 participants completed interviews: nurse specialists (n=16), consultant psychiatrists (n=6), nursing managers (n=2), emergency medicine staff (n=2) and members of the national programme team (n=4). Enablers of implementation included the introduction of national, standardised guidance for EDs; implementation strategies led by the national programme team; and training and support for nurse specialists. The following inner-setting factors were perceived as barriers to implementation in some hospitals: limited access to a designated assessment room, delayed access to clinical input and poor collaboration with ED staff. Overall, these barriers dissipated over time, owing to implementation strategies at national and local levels. The varied availability of aftercare impacted providers' ability to deliver the programme and the adaptability of programme delivery had a mixed impact across hospitals. CONCLUSIONS: The perceived value of the programme and national leadership helped to advance implementation. Strategies related to ongoing training and education, developing stakeholder interrelationships and evaluation and monitoring have helped address implementation barriers and promote continued sustainment of the programme. Continued efforts are needed to support nurse specialists delivering the programme and foster partnerships with community providers to improve the transition to aftercare.
