Agreement on validity of available patient advance directives

An advance directive could be rated as valid (“Yes”), invalid (“No”), or unsure. This figure compares the evaluations given by residents in training versus senior physicians and of doctors versus relatives. “Both” indicates agreement between evaluations. Specifically, there was only slight, insignificant agreement between residents’ and senior physicians’ evaluations of advance directive validity (AC1 = 0.24; 95% confidence interval: –0.03 to 0.50; p = 0.079). There was only fair, insignificant agreement between doctors’ and relatives’ evaluations (AC1 = 0.35; 95% confidence interval: –0.01 to 0.71; p = 0.059)
