BackgroundRemote mental health consultations were swiftly implemented across mental health services during the COVID-19 pandemic. Research has begun to inform future design and delivery of telemental health services. Exploring the in-depth experiences of those involved is important to understand the complex, multi-level factors that influence the implementation of remote mental health consultations. The aim of this study was to explore stakeholder perspectives and experiences of the implementation of remote mental health consultations during the COVID-19 pandemic in Ireland.MethodsA qualitative study was conducted whereby semi-structured, individual interviews were undertaken with mental health providers, service users, and managers (n= 19) to acquire rich information. Interviews were conducted between November 2021 and July 2022. The interview guide was informed by the Consolidated Framework for Implementation Research (CFIR). Data were analysed thematically using a deductive and inductive approach.ResultsSix themes were identified. The advantages of remote mental health consultations were described, including convenience and increased accessibility to care. Providers and managers described varying levels of success with implementation, citing complexity and incompatibility with existing workflows as barriers to adoption. Providers’ access to resources, guidance, and training were notable facilitators. Participants perceived remote mental health consultations to be satisfactory but not equivalent to in-person care in terms of quality. Views about the inferior quality of remote consultations stemmed from beliefs about the inhibited therapeutic relationship and a possible reduction in effectiveness compared to in-person care. Whilst a return to in-person services was mostly preferred, participants acknowledged a potential adjunct role for remote consultations in certain circumstances.ConclusionsRemote mental health consultations were welcomed as a means to continue care during the COVID-19 pandemic. Their swift and necessary adoption placed pressure on providers and organisations to adapt quickly, navigating challenges and adjusting to a new way of working. This implementation created changes to workflows and dynamics that disrupted the traditional method of mental health care delivery. Further consideration of the importance of the therapeutic relationship and fostering positive provider beliefs and feelings of competence are needed to ensure satisfactory and effective implementation of remote mental health consultations going forward.Supplementary InformationThe online version contains supplementary material available at 10.1186/s12913-023-09529-x.
