Cost-Effectiveness of ESWT Plus Rehabilitation vs Rehabilitation Alone in Post-Burn Scars

Condition(s) studied

Investigational drug(s) / intervention(s)

ESWT Combined with Standard Rehabilitation: Participants in the experimental arm will receive a combination intervention comprising ESWT delivered by certified technicians using a validated device for post-burn scars, along with standard rehabilitation therapy. ESWT sessions will be standardized (e.g., 3,000 pulses per session, weekly for 8 weeks) and will be integrated with a comprehensive rehabilitation program encompassing physical therapy, scar management exercises, and patient education. The specific parameters (e.g., energy level, frequency) will be reported based on established guidelines.

Standard Rehabilitation Therapy Alone: Participants in the control arm will receive the institution's standard rehabilitation therapy for managing post-burn scars, including physical therapy, occupational therapy, and scar-massage techniques. Treatment frequency and duration will mirror the experimental arm's rehabilitation component to ensure consistency. No ESWT will be provided.

Study summary

This randomized controlled trial (RCT) will evaluate the cost-effectiveness of combining extracorporeal shock wave therapy (ESWT) with standard rehabilitation versus standard rehabilitation alone for the management of hypertrophic post-burn scars in adults. The study will assess clinical outcomes-such as pain intensity, pruritus, and scar quality-alongside economic outcomes including cost per quality-adjusted life year (QALY) gained, direct medical costs, and indirect costs (e.g., absenteeism and reduced productivity). Results will inform health policy and resource allocation decisions for advanced burn rehabilitation interventions.

Eligibility

Primary outcome measure(s)

• Pain Intensity (Visual Analog Scale [VAS]) — Assessed at baseline, 1 month, 3 months, and 6 months post-intervention.
  This measure evaluates the intensity of pain experienced by participants, using a 10-centimeter Visual Analog Scale where 0 indicates "no pain" and 10 indicates "worst pain imaginable." The VAS is a validated, standardized tool allowing for quantitative measurement of patient-reported pain intensity changes over time.
• Cost per Quality-Adjusted Life Year (QALY) Gained — Evaluated at 6 months post-intervention.
  This economic outcome will be determined by calculating the incremental cost per QALY gained using validated health-related quality-of-life instruments (eg, EQ-5D) alongside hospital billing data. It compares the cumulative costs (both direct and indirect) and QALYs between the ESWT plus rehabilitation arm versus the rehabilitation alone arm over a 6-month period.
