Agreement Between Patient and Surrogate Assessments of Pre-Critical Illness Physical Function
Authors' conclusion
We found fair agreement and moderate correlation on previously validated self-report questionnaires of physical function. Patients reported better function than their surrogates particularly at lower levels of function.
Study context
- Population
- Patients treated for respiratory failure, shock, and/or sepsis and their surrogates; physical function anchored on the 4 weeks before admission (virtual Short Physical Performance Battery (vSPPB), SARC-F, FRAIL)
- Participants
- 75 patient-surrogate dyads
- Exposure
- Patient vs Surrogate
- Outcome
- Agreement between patient and surrogate responses on composite scores from each questionnaire
