BACKGROUND

Digital health interventions have the potential to improve the efficacy and accessibility of mental health services for people with severe mental health problems, but their integration into routine practice is a challenge. The real-world implementation of digital health interventions should be considered alongside digital intervention development. However, little is known about the quality of implementation research in this area, including the extent to which implementation science theories, models and frameworks are used. The aim of this review was to synthesise evidence regarding the application of theories, models and frameworks in research investigating the implementation of digital health interventions in services for people with severe mental health problems. Secondary aims were to consider the contexts within which studies had been undertaken and the degree of service user involvement in this research.

METHODS

A scoping review method was employed. Electronic databases were systematically searched for published papers in English and reference lists of included studies were hand searched. Included studies used an implementation science theory, model, or framework to understand, guide or evaluate the implementation of digital health interventions in services for people with severe mental health problems.

RESULTS

Twelve eligible studies were identified. Studies were primarily undertaken in community mental health services with staff participants and there was variation in the types of digital interventions that were investigated. Eight different implementation science theories, models, and frameworks were used and were mainly employed to guide qualitative analysis. Most studies were undertaken in the early exploratory stages of implementation projects and there was little evidence regarding factors affecting the longer-term sustainment of digital health interventions in practice. Only one study reported the inclusion of service users in the design of the implementation study.

CONCLUSIONS

The use of implementation theories, models, and frameworks in efforts to implement digital health interventions in routine care for people with severe mental health problems is limited. Researchers should consider integrating such approaches throughout the research process and ensure service users are involved in this work. Further research regarding implementation processes, and the reach and sustainment of digital health interventions in routine practice, is required.
