Multicenter Study Observational Study
Inter-observer reliability of preoperative cardiopulmonary exercise test interpretation: a cross-sectional study.
Despite the increasing importance of cardiopulmonary exercise testing (CPET) for preoperative risk assessment, the reliability of CPET interpretation is unclear. We aimed to assess inter-observer reliability of preoperative CPET. ⋯ Inter-observer reliability of interpretation of numerical values of two commonly used CPET variables was good (>80%). However, inter-observer agreement regarding the presence of a reportable value was less consistent.
