College of American Pathologists Cancer Protocols: Optimizing Format for Accuracy and Efficiency

-The data in College of American Pathologists cancer protocols have to be presented effectively to health care providers. There is no consensus on the format of those protocols, resulting in various designs among pathologists. Cancer protocols are independently created by site-specific experts, so there is inconsistent wording and repetition of data. This lack of standardization can be confusing and may lead to interpretation errors.

-To define a synopsis format that is effective in delivering essential pathologic information and to evaluate the aesthetic appeal and the impact of varying format styles on the speed and accuracy of data extraction.

-We queried individuals from several health care backgrounds using varying formats of the fallopian tube protocol of the College of American Pathologists without content modification to investigate their aesthetic appeal, accuracy, efficiency, and readability/complexity. Descriptive statistics, an item difficulty index, and 3 tests of readability were used.

-Columned formats were aesthetically more appealing than justified formats (P < .001) and were associated with greater accuracy and efficiency. Incorrect assumptions were made about items not included in the protocol. Uniform wording and short sentences were associated with better performance by participants.

-Based on these data, we propose standardized protocol formats for cancer resections of the fallopian tube and the more-familiar colon, employing headers, short phrases, and uniform terminology. This template can be easily and minimally modified for other sites, standardizing format and verbiage and increasing user accuracy and efficiency. Principles of human factors engineering should be considered in the display of patient data.
