A Hybrid Web-Based and In-Person Self-Management Intervention Aimed at Preventing Acute to Chronic Pain Transition After Major Lower Extremity Trauma: Feasibility and Acceptability of iPACT-E-Trauma

BACKGROUND: A transition from acute to chronic pain frequently occurs after major lower extremity trauma. While the risk factors for developing chronic pain in this population have been extensively studied, research findings on interventions aiming to prevent chronic pain in the trauma context are scarce. Therefore, we developed a hybrid, Web-based and in-person, self-management intervention to prevent acute to chronic pain transition after major lower extremity trauma (iPACT-E-Trauma). OBJECTIVE: This study aimed to assess the feasibility and acceptability of iPACT-E-Trauma. METHODS: Using a descriptive design, the intervention was initiated at a supra-regional level-1 trauma center. Twenty-eight patients ≥18 years old with major lower extremity trauma, presenting with moderate to high pain intensity 24 hours post-injury were recruited. Feasibility assessment was two-fold: 1) whether the intervention components could be provided as planned to ≥80% of participants and 2) whether ≥80% of participants could complete the intervention. The rates for both these variables were calculated. The E-Health Acceptability Questionnaire and the Treatment Acceptability and Preference Questionnaire were used to assess acceptability. Mean scores were computed to determine the intervention's acceptability. RESULTS: More than 80% of participants received the session components relevant to their condition. However, the Web pages for session 2, on the analgesics prescribed, were accessed by 71% of participants. Most sessions were delivered according to the established timeline for ≥80% of participants. Session 3 and in-person coaching meetings had to be provider earlier for ≥35% of participants. Session duration was 30 minutes or less on average, as initially planned. More than 80% of participants attended sessions and <20% did not apply self-management behaviors relevant to their condition, with the exception of deep breathing relaxation exercises which was not applied by 40% of them. Web and in-person sessions were assessed as very acceptable (mean scores ≥3 on a 0 to 4 descriptive scale) across nearly all acceptability attributes. CONCLUSIONS: Findings showed that the iPACT-E-Trauma intervention is feasible and was perceived as highly acceptable by participants. Further tailoring iPACT-E-Trauma to patient needs, providing more training time for relaxation techniques, and modifying the Web platform to improve its convenience could enhance the feasibility and acceptability of the intervention.
