Near real-time patient experience feedback (NRTPEF) can enable a patient-centric, immediate service recovery but has not been widely used in inpatient rehabilitation. We 1) assess the utility, feasibility, and acceptability of implementing a new NRTPEF, perceived by patients and providers; and 2) understand how the NRTPEF became embedded into routine provider practices. Mixed methods process evaluation of the 8-month implementation of an innovative NRTPEF in an inpatient rehabilitation unit, using interviews and focus groups with all the service-unit leaders and interviews with a randomised sample of patients. Beyond descriptive statistics and content analysis, the Normalisation Process Theory (NPT) informed a framework analysis. Patients and service-unit leaders perceived high utility in the NRTPEF (median: 9 for both; 0-10 scale) and qualitative comments emphasised the value of providing/obtaining timely feedback. The system was found feasible and acceptable for patients (median: 9.5), but with an improvement margin for providers (median: 7.3). Suggestions include strengthening the data-relay format. Even in the pilot form, providers found the NRTPEF became embedded into practice (median 10; average: 8.6). The analysis based on the NPT shows how providers saw differential value, engaged with, and used the patient feedback into reconfigured practices. An innovative NRTPEF was found useful, feasible and acceptable, but with refinement opportunities before scale-up.
