Nursing staff perspectives of continuous remote vital signs monitoring on surgical wards: Theory elicitation for a realist evaluation

RATIONALE, AIMS AND OBJECTIVES: Continuous remote monitoring (CRM) provides a novel solution to the challenges of monitoring patients' vital signs in hospital, but the results of quantitative studies have been mixed. Acceptance by staff is a crucial determinant of the success of healthcare technologies and may explain these discrepancies. Drawing on the approach of realist evaluation, this paper aims to identify theories about how, why and in what conditions nursing staff perceptions vary regarding the CRM of patients' vital signs. METHODS: Multiple methods were used to elicit theories about factors likely to facilitate or impede the successful implementation of continuous remote vital signs monitoring. This included a literature review, consultation with patients and observational work conducted during a randomized controlled trial (RCT) of CRM. In addition, a priori theories developed through informal interactions with patients and ward staff during the day‐to‐day set‐up of the trial were included. RESULTS: The findings suggest that the perceptions of nursing staff regarding remote monitoring can be influenced by the type of patients under their care and their previous experience of telemetry. Factors which may undermine the engagement of staff are perceived staff burden, which can be dependent on contextual factors such as staffing levels, time of day and senior staff attitudes. Staff attitudes are also likely to be influenced by patient perspectives and the utility of the devices associated with remote monitoring. The successful implementation of CRM may be dependent on staff training, research staff input and hospital culture. CONCLUSIONS: Theories regarding nursing staff engagement with remote monitoring are numerous, varied and contradictory. The theories elicited in this initial phase will be refined during interviews with the nursing staff involved with the RCT.
