Defining the Minimal Clinically Important Difference and Patient-acceptable Symptom State Score for Disability Assessment in Surgical Patients
Key result
Post-surgery WHODAS 2.0 scores establish a ~5% minimal clinically important difference.
- n=4,361
Why the study?
The minimal clinically important difference and patient-acceptable symptom state scores for the World Health Organization Disability Assessment Schedule 2.0 were uncertain in patients recovering from surgery.

Implication
These thresholds may aid WHODAS 2.0 interpretation after surgery; extends prior validation but leaves open prospective confirmation before routine use.

Intervention
World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) assessment
O
Outcome
Minimal clinically important difference (MCID) and patient-acceptable symptom state (PASS) scores for the WHODAS 2.0patient reported
A change of 5% or more in the WHODAS 2.0 score represents a clinically important change in disability for surgical patients, with scores <16% indicating an acceptable symptom state.

Shulman et al. (2020) conducted a cohort in Patients recovering from surgery (n=4,361). World Health Organization Disability Assessment Schedule 2.0 was evaluated on Minimal clinically important difference and patient-acceptable symptom state scores. The World Health Organization Disability Assessment Schedule 2.0 demonstrated a minimal clinically important difference of 5% and a patient-acceptable symptom state score of 16% after surgery.
