Barriers and Facilitators to Implementing a Nurse‐Led Information System for Older Adult Patients' Post‐Discharge Self‐Care: An Exploratory Sequential Mixed‐Methods Study

AimTo explore determinants impacting an Electronic Health Record‐based information system implementation and their association with implementation fidelity based on the Theoretical Domains Framework (TDF) from nurses' perspectives.DesignExploratory sequential mixed‐method design.MethodsIn stage one, semi‐structured interviews with 53 purposively selected nurses informed the exploration of TDF domains influencing the implementation of the information system with directed content analysis. In stage two, a cross‐sectional survey, informed by the qualitative findings, was conducted among 482 nurses to identify the most relevant and relatively important TDF domains by running generalised linear regression models.ResultsThe qualitative interviews generated 13 TDF domains that were identified as major influencing factors, including technology characteristics, knowledge, attitudes, role agreement, self‐efficacy, goal‐setting, information circulation, and communication among nurses. Quantitative findings showed that 70% of nurses used and printed the written form through the information system, and only 34% offered verbal education consistently. Regression analysis identified nine domains that were relevant and important factors for implementation fidelity, including knowledge, skills, role identity, beliefs in consequences, beliefs in capabilities, intentions, goals, memory and decision processes, and environmental context.ConclusionOur findings confirmed previous evidence on determinants of implementing digital health technologies, including knowledge, competencies, perceived effectiveness, role agreement, intentions, decision processes, and environmental context. Additionally, we highlighted the importance of goal‐setting for successful implementation.ImpactThis study investigated the relatively important associated factors that can impact the successful implementation of the nurse‐led information system for post‐acute care based on nurses' perspectives. These results can guide nurse practitioners in implementing similar initiatives and support evidence‐based decision‐making. Researchers can also further investigate the relationships between the identified determinants.Reporting MethodJournal Article Reporting Standards for Mixed Methods Research.Patient or Public ContributionNo patient or public contribution.
