—Dr Rubin and colleagues1 erroneously suggest that a simple intervention might increase the completion of proxy forms.Rubin et al claim to have increased use of proxy forms from 5.8% to 18.5%. They claim their data—particularly the very low baseline rate of completing proxy forms—are comparable with those of other studies.
