Brief Summary

This study aims to evaluate the effectiveness of a digital patient education solution, CHUVeduc@home, in improving preoperative preparation for patients undergoing total hip or knee arthroplasty. In Switzerland, many patients receive joint replacements each year to relieve osteoarthritis-related pain. With shorter hospital stays, adequate preparation before surgery has become increasingly important. A total of 160 patients will be randomized into two groups: Intervention group: access to CHUVeduc@home before surgery. Control group: standard preoperative preparation (group information session and consultation). All participants will complete questionnaires through the application. No additional visits are required. The intervention lasts approximately 12 weeks. The primary goal is to determine whether digital education increases patient knowledge, confidence, and satisfaction, and facilitates recovery and return home after surgery. Participation is voluntary and can be withdrawn at any time.

Outcome Measures

Primary Outcomes (2)

  • Number of patient calls to the remote care center (CTS)

    The primary outcome is the total number of calls initiated by patients to the remote care support center (CTS) during the intervention period. This measure will assess the impact of the digital education tool on patient autonomy and the need for additional support. A lower number of calls is expected to reflect improved patient preparation and self-management.

    During the intervention period (from inclusion until surgery, up to 6 weeks)

  • Reason for contacts, the severity of alerts

    This secondary objective aims to analyze the specific reasons for patient contacts, assess the severity of alerts generated, and evaluate the potential financial benefits associated with a decrease in the number of contacts, thereby providing a comprehensive understanding of the impact of the telemonitoring intervention.

    During the intervention period (from inclusion until surgery, up to 6 weeks)

Secondary Outcomes (15)

  • Patient-reported health status and quality of life (EQ-5D-5L)

    At preadmission (3 days before surgery), and 6 weeks postoperatively

  • Patient satisfaction (ANQ questionnaire)

    1 week after hospital discharge

  • Patient engagement (Patient Activation Measure [PAM-13]

    At baseline during the intervention period , at preadmission (3 days before surgery) and 6 weeks postoperatively

  • Physical activity (International Physical Activity Questionnaire [IPAQ])

    At baseline during the intervention period and 6 weeks postoperatively

  • Fear and anxiety related to surgery (Survey of Surgical Fear [SSF])

    At baseline during the intervention period and at preadmission (3 days before surgery)

  • +10 more secondary outcomes

Study Arms (2)

Intervention Group: access to CHUVeduc@home before surgery

EXPERIMENTAL

Intervention Group - Pathway with CHUVeduc@home This group follows the standard preoperative pathway, complemented by personalized digital preparation through the CHUVeduc@home application, available 2 to 6 weeks before surgery.

Behavioral: Digital Preoperative Education with CHUVeduc@home

Control Group - Standard Care Pathway

ACTIVE COMPARATOR

Control Group - Standard Care Pathway This group follows the standard clinical care pathway established at CHUV for patients undergoing total hip or knee arthroplasty. The main steps include: * Consultation with the surgeon * Group information session * Preoperative consultation * Hospital stay for surgery * Discharge and return home * Telemonitoring with CHUV@home after surgery * Postoperative follow-up visit at 6 weeks Participants in this group also use the CHUV@home application to complete study-specific questionnaires; however, they do not receive any additional educational content prior to surgery.

Behavioral: Standard Care Pathway

Interventions

Digital Preoperative Education with CHUVeduc@homeBEHAVIORAL

The intervention consists of a personalized digital education program delivered through the CHUVeduc@home mobile application, integrated within the existing CHUV@home platform. The application is available to patients 2 to 6 weeks prior to surgery and provides: * Educational modules covering postoperative recovery, pain management, rehabilitation, and discharge planning. * Quizzes and knowledge tests to reinforce patient understanding. * Practical advice sheets for concrete preparation. * Individualized pacing and guidance tailored to patient needs. * Notifications prompting completion of study questionnaires. The goal of the intervention is to improve patient health literacy, reduce preoperative anxiety, increase confidence, and facilitate recovery and return home after total hip or knee arthroplasty.
