Information collected included demographics, osteoarthritis severity, opioid and antidepressant use, and pre- and post-procedure numeric rating scale (NRS) scores for pain. Primary outcome measures were pre-post difference NRS score, considering clinically meaningful a ≥2-point improvement in NRS and ≥50 % pain reduction.

After slide randomization, a Google Forms test was created to capture observer responses. Two sets of observers were used to represent novice (DB,KG) and experienced (MF,ER) observers. Each observer independently reviewed the testing slide set, recording a total of 300 responses for the three binary decisions on each slide: which image was true, which corrective maneuver (oblique or tilt) was required to make the untrue image a true image, and finally, which was the direction of the appropriate corrective maneuver (right or left oblique/cranial or caudal tilt).

Given the increased utilization for this purpose, it is essential to evaluate and study the consistency and reliability of artificial intelligence (AI) responses. Low back pain (LBP) remains one of the most frequently seen chief complaints in primary care and interventional pain management offices.</div></div><div><h3>Objective</h3><div>This study assesses the readability, accuracy, and overall utility of ChatGPT's ability to address patients' questions concerning low back pain. Our aim is to use clinician feedback to analyze ChatGPT's responses to these common low back pain related questions, as in the future, AI will undoubtedly play a role in triaging patients prior to seeing a physician.</div></div><div><h3>Methods</h3><div>To assess AI responses, we generated a standardized list of 25 questions concerning low back pain that were split into five categories including diagnosis, seeking a medical professional, treatment, self-treatment, and physical therapy. We explored the influence of how a prompt is worded on ChatGPT by asking questions from a 4th grader to a college/reference level. One board certified interventional pain specialist, one interventional pain fellow, and one emergency medicine resident reviewed ChatGPT's generated answers to assess accuracy and clinical utility. Readability and comprehensibility were evaluated using the Flesch-Kincaid Grade Level Scale. Statistical analysis was performed to analyze differences in readability scores, word count, and response complexity.</div></div><div><h3>Results</h3><div>How a question is phrased influences accuracy in statistically significant ways. Over-simplification of queries (e.g. to a 4th grade level) degrades ChatGPT's ability to return clinically complete responses. In contrast, reference and neutral queries preserve accuracy without additional engineering. Regardless of how the question is phrased, ChatGPT's default register trends towards technical language. Readability remains substantially misaligned with health literacy standards. Verbosity correlates with prompt type, but not necessarily accuracy. Word count is an unreliable proxy for informational completeness or clinical correctness in AI outputs and most errors stem from omission, not commission. Importantly, ChatGPT does not frequently generate false claims.</div></div><div><h3>Conclusion</h3><div>This analysis complicates the assumption that “simpler is better” in prompting LLMs for clinical education.
