Assessing risk communication in breast cancer: are continuous measures of patient knowledge better than categorical?
The continuous measures led to more efficient sample sizes and to rejection of the null hypothesis of no intervention effect. However, the difference in sensitivity of the continuous measures was not statistically significant, and the performance of the categorical measure depends on the researcher's categorical cutoff for accuracy. Continuous measures of patient accuracy may be more sensitive and efficient, while categorical measures may be more clinically relevant.
This study provides some evidence that ECPs can accurately report on whether their actions, at the time of that care episode, result in a patient avoiding attendance at an ED or avoiding a hospital admission.
