The aim of this study was to investigate the implementation of a novel electronic bedside nursing chart in an acute hospital setting. The case study used multiple data sources captured within a real-life clinical ward context. Quantitative findings included significant reductions in nurse-reported missed care (P<0.05) and increased mean time spent at the bedside (from 21 to 28min h-1; P<0.0001); reductions in patient-reported missed care and nurses' walking distances were not significant. Qualitative themes included: (1) inconsistent expectations (perceptions about potential vs actual functionality and benefits of the technology); (2) decisional conflict between managers and end-user nurses (discordance between governance decisions and clinical operations; 30% of beds were closed and six of the eight trained nurse 'super-users' were moved from the pilot ward); and (3) workflow effects (ergonomic set-up of the digital interface). This study highlights the complex challenges of implementing and examining the effects of technology to support nursing care. Shared understanding of the technology goals and project scope in relation to nursing care and flexible and adaptive project and contingency planning are fundamental considerations. Complexity, unpredictability and uncertainty of 'usual business' are common confounders in acute hospital settings.
