Cost-utility analysis and impact on the environment of videoconference in pressure injury. A randomized controlled trial in individuals with spinal cord injury.

Study Design: A prospective randomized controlled trial (RCT) in persons with spinal cord injury (SCI) and ongoing pressure injury (PI).

Objectives: The main aim was to perform a cost-utility analysis (CUA) alongside the RCT comparing regular care to regular care with additional videoconference consultations. Secondary aims were to assess costs and greenhouse gas emission related to transportation in the two study groups.

Setting: Two spinal cord units in Norway.

Methods: Participants were allocated to a regular care group (RCG) and a regular care group with additional videoconference (VCG), in a 1-year follow-up between 2016 and 2018. Costs were prospectively collected, and health-related quality of life (HRQoL) data were collected at baseline and 12 months. The outcome was quality-adjusted life years (QALYs), derived from the EQ-5D-5L questionnaire. Results are reported as incremental cost-effectiveness ratio (ICER), expressed as the cost per additional QALY gained. Transportation related costs and environmental emissions were compared by t-tests.

Results: There were 56 participants included, 28 in each group. Of these 27 in the VCG and 26 in the RCG completed. Three participants died. The mean cost per patient was € 8819 in the VCG and € 3607 in the RCG, with 0.1 QALYs gained in the VCG. No significant differences were identified regarding HRQoL or secondary outcomes.

Conclusion: The VCG costs € 5212 more for an additional 0.1 QALYs, giving an ICER of € 52,120 per QALY. No significant differences were found regarding transportation-related costs, or emission of greenhouse gases.
