ChatGPT can simplify complex postoperative instructions to a sixth-grade reading level, enhancing patient comprehension and safety. Prompting the AI for a lower grade level improves readability without sacrificing essential care information.
Area of Science:
- Medical Education
- Artificial Intelligence in Healthcare
- Patient Communication
Background:
- Postoperative discharge instructions often exceed recommended reading levels, hindering patient understanding and adherence.
- Effective patient communication is crucial for successful home recovery and reducing readmissions.
- National guidelines advocate for a sixth-grade reading level for patient education materials.
Purpose of the Study:
- To evaluate the effectiveness of ChatGPT in rewriting postoperative instructions to a sixth-grade reading level.
- To assess the readability, understandability, actionability, and safety of AI-generated instructions.
- To compare AI-rewritten instructions with original materials across four plastic surgery subspecialties.
Main Methods:
- Original postoperative instructions from four plastic surgery procedures were collected.
- ChatGPT was employed to rewrite instructions at fourth- and sixth-grade reading levels.
- Readability, understandability, actionability, and safety were assessed using validated tools and surgeon review.
Main Results:
- Original instructions averaged seventh- to eighth-grade reading levels.
- ChatGPT-rewritten instructions at the fourth-grade level improved readability but decreased actionability.
- Understandability scores improved with lower reading levels, and safety was maintained across all rewrites.
Conclusions:
- ChatGPT effectively adapts postoperative instructions to a sixth-grade reading level, enhancing patient comprehension.
- A sixth-grade reading level optimizes the balance between understandability and actionability for patient instructions.
- AI tools like ChatGPT show promise in improving patient care through accessible medical information.
