Abstract
BACKGROUND: The implementation of computerised clinical decision support systems has the potential to enhance healthcare by improving patient safety, practitioner performance, and patient outcomes. Notwithstanding the numerous advantages, the uptake of clinical decision support systems remains constrained, thereby impeding the full realisation of their potential. To ensure the effective and successful implementation of these systems, it is essential to identify and analyse the reasons for their low uptake and adoption. This protocol outlines an umbrella review, which will synthesise the findings of existing literature reviews to generate a comprehensive overview of the barriers and facilitators to the implementation and adoption of decision support systems across healthcare settings. METHODS: This umbrella review protocol was developed in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) guidelines. Searches for eligible articles will be conducted in four electronic bibliographic databases, including PubMed/MEDLINE, IEEE Xplore, Scopus, and Web of Science. Obtained results will be independently screened by four reviewers based on pre-defined eligibility criteria. The risk of bias will be assessed for all eligible articles. Data on barriers and facilitators to the implementation and adoption of clinical decision support systems will be extracted, summarised, and further categorised into themes that aim to describe the originating environment or concept of the respective factor. The frequency of all identified barriers and facilitators within the group of included reviews will be determined in order to establish a prioritisation of the factors. DISCUSSION: This umbrella review protocol presents a methodology for the systematic synthesis of barriers and facilitators to the implementation and adoption of clinical decision support systems across healthcare settings. The umbrella review will enable the development of novel implementation and adoption strategies that reinforce the identified facilitators and circumvent barriers, thereby promoting the use-oriented evaluation and effective utilisation of clinical decision support systems.
