Bridging the Knowledge Gap: An Examination of the Ideal Postoperative Autologous Breast Reconstruction Educational Material with A/B Testing.

BACKGROUND

Poor health literacy is an epidemic in the United States, associated with higher mortality rates and poor postoperative care. Autologous breast reconstruction is highly complex, and the identification of complications is difficult even for non-plastic surgeon practitioners. The authors sought to explore the problem of health literacy in this context and identify the ideal postoperative patient education materials.

METHODS

Available online postoperative patient education materials for autologous breast reconstruction and corresponding readability scores were assessed. To derive the ideal formula for materials, the authors crowd-sourced quizzes with A/B testing, a method to examine the outcome of two versions of a single variable. The authors implemented their findings and compared performance on postoperative quizzes with and without oral reinforcement.

RESULTS

Of the 12 postoperative flap complication patient education materials found through an Internet search, the average grade level readability level was 9.9. Only one of 12 (8.3 percent) mentioned symptoms and signs of flap compromise. The A/B tests result revealed that text approximately 400 to 800 words written on a sixth-grade level led to the highest quiz scores. Patients scored significantly higher on the postoperative day-2 quiz when patient education materials, modeled after these findings, were reinforced with oral presentation (p = 0.0059). Retention of high quiz scores remained at postoperative day 10.

CONCLUSIONS

Currently available patient education materials are at a high reading level and lack specific information on the identification of flap compromise. The authors propose the most effective postoperative instructions to be approximately 400 to 800 words written on a grade-six level with images and oral reinforcement.
