Cost‐Effectiveness of Community‐Based Diet and Exercise for Patients with Knee Osteoarthritis and Obesity or Overweight
Authors' conclusion
The community-based D + E program for persons with knee OA and BMI >27kg/m2 could be cost-effective for willingness-to-pay thresholds greater than $62,000/QALY.
Study context
- Population
- Simulated cohort with knee osteoarthritis (OA) and body mass index (BMI) >27 kg/m² (mean age 65 years, BMI 37 kg/m², WOMAC pain 38 on 0–100)
- Comparison
- Usual care (UC) vs UC + health education (HE) vs UC + (D + E), each vs next-best strategy by increasing lifetime cost
- Outcome
- QALYs, cost and incremental cost-effectiveness ratios (ICERs)
- Follow-up
- Lifetime
Methodological detailsmodel-based, Osteoarthritis Policy Model, lifetime horizon, societal perspective, inputs from the WE-CAN trial
- Model-based
- Osteoarthritis Policy Model
- Lifetime horizon
- Societal perspective
