Reliability of pre-admission patient-reported outcome measures postoperatively assessed via proxies: a prospective, multicenter observational study
Authors' conclusion
The reliability of proxy assessment with the instruments used was insufficient, exhibiting a significant bias in the pre-admission status of ICU patients
Study context
- Population
- Surgical adults able to answer PROMs (SF-36, EQ-5D-5L, WHODAS 2.0, IADL, Barthel Index) independently, with a proxy available, Germany
- Participants
- 204 patient-proxy pairs
- Exposure
- Proxy vs patient assessment of pre-admission status via PROMs
- ICUn = 102
- Outcome
- Reliability of proxy assessment of pre-ICU admission status (Bland-Altman plots, Cohen's kappa)
Methodological detailsmulticentre, two tertiary care university hospitals, Patients interviewed preoperatively; proxies interviewed postoperatively in the ICU or normal ward, Median patient and proxy age 69 and 64 years; 41% and 68% female
