BackgroundIntensive care is lagging with digital transformation. It is essential to provide evidence and guidelines for integrating digital health technologies into the intensive care unit (ICU).We evaluated the implementation of a remote patient monitoring platform and derived an implementation framework proposal for digital health technology in an ICU.MethodsWe conducted this study from May 2018 to March 2020 during the implementation of a tablet-computer based remote patient monitoring system. The system was installed in the ICU of a large German university hospital as a supplementary monitoring device. Following a hybrid qualitative approach with inductive and deductive elements, we used the Consolidated Framework for Implementation Research and the Expert Recommendations for Implementing Change to analyze the transcripts of seven semi-structured interviews with ICU clinical stakeholders and quantifiable questionnaire data. Results of the qualitative analysis, together with the findings from informal meetings, field observations, and previous explorations, provided the basis for the derivation of the proposed framework. Results Inductive analysis of the interview transcripts revealed an insufficient implementation process because of a lack of staff engagement and little perceived benefits from the novel solution. The ICU was not considered the most suitable for remote patient monitoring, as the staff’s presence and monitoring coverage were high. We propose an implementation framework for digital technologies, including strategies to apply before and during implementation, targeting the implementation setting by involving all stakeholders, assessing the intervention’s adaptability, facilitating the implementation process, and maintaining a vital feedback culture. Setting up a unit responsible for implementation, taking into account the guidance of an implementation advisor, and building on existing institutional capacities could improve the institutional context of implementation projects.Conclusions The ICU provides an exceptional setting for the introduction of digital health technology because it is a high-tech environment involving multiple professions and high-stress levels. Before implementation, the need for innovation and the ICU’s readiness to change should be assessed. During implementation, a clinical team should ensure transparent communication and continuous feedback. The establishment of an implementation unit is recommended to promote a sustainable implementation culture and to benefit from existing networks.Trial registrationClinicalTrials.gov NCT03514173; https://clinicaltrials.gov/ct2/show/NCT03514173
