Description Usage Format Source References
The right heart catheterization (RHC) dataset is publicly available on the Vanderbilt Biostatistics website. RHC is a diagnostic procedure for directly measuring cardiac function in critically ill patients. The dependent variable is 1 if a patient survived after 30 days of admission, 0 if a patient died within 30 days. The treatment variable is 1 if RHC was applied within 24 hours of admission, and 0 otherwise. The sample size was n = 5735, and 2184 patients were treated with RHC. Connors et al. (1996) used a propensity score matching approach to study the efficacy of RHC, using data from the observational study called SUPPORT (Murphy and Cluff, 1990). Many authors used this dataset subsequently. The 72 covariates are constructed, following Hirano and Imbens (2001).
