Can Generative Artificial Intelligence Enhance Health Literacy About Lateral Epicondylitis?

INTRODUCTION: Health literacy is a critical determinant of a patient's overall health status, and studies have demonstrated a consistent link between poor health literacy and negative health outcomes. The Centers for Disease Control and Prevention (CDC) and the National Institutes of Health (NIH) advise that patient educational materials (PEMs) should be written at an eighth-grade reading level or lower, matching the average reading level of adult Americans. The purpose of this study was to investigate the ability of generative artificial intelligence (AI) to edit PEMs from orthopaedic institutions to meet the CDC and NIH guidelines. METHODS: PEMs about lateral epicondylitis (LE) from the top 25 ranked orthopaedic institutions from the 2022 U.S. News & World Report Best Hospitals Specialty Ranking were gathered. ChatGPT Plus (version 4.0) was then instructed to rewrite PEMs on LE from these institutions to comply with CDC and NIH-recommended guidelines. Readability scores were calculated for the original and rewritten PEMs, and paired t-tests were used to determine statistical significance. RESULTS: Analysis of the original and edited PEMs about LE revealed significant reductions in reading grade level and word count of 3.70 ± 1.84 (p<0.001) and 346.72 ± 364.63 (p<0.001), respectively. CONCLUSION: Our study demonstrated generative AI's ability to rewrite PEM about LE at a reading comprehension level that conforms to the CDC and NIH guidelines. Hospital administrators and orthopaedic surgeons should consider the findings of this study and the potential utility of artificial intelligence when crafting PEMs of their own.

Reoperation, Readmission, and Postoperative Bleeding in Pediatric Cerebral Palsy Patients Undergoing Spinal Arthrodesis.

Background Cerebral palsy (CP) is one of the most common neuromuscular disorders in children, and spinal abnormalities are vastly more common in people with CP compared to the general population. Further investigation is needed to improve our understanding of the perioperative factors that place children with CP at greater risk of postoperative complications. This study aims to investigate (1) whether pediatric CP patients have higher rates of postoperative complications after spinal fusion and (2) risk factors for postoperative bleeding, readmission, and reoperation. Methodology The 2019 American College of Surgeons National Surgical Quality Improvement Program Pediatric database was used for this study. Chi-square tests were used to compare patient demographics, frequency of comorbidities, intraoperative factors, and postoperative complications between CP and non-CP patients. Multivariable logistic regression modeling was conducted to determine if CP was an independent risk factor for the composite variable that included postoperative bleeding, readmission, and reoperation. Results A total of 4,445 patients were included in the study, with 606 CP and 3,839 non-CP patients. Several comorbidities were more prevalent in the CP cohort, most notably asthma, gastrointestinal disease, previous cardiac surgery, and hematologic disorders. Multivariable logistic regression modeling revealed that CP, older age, non-Caucasian race, American Society of Anesthesiologists (ASA) class of 3 or higher, posterior surgical approach, previous cardiac surgery, and ostomy were significantly correlated with higher postoperative complications. Conclusions This study demonstrates that CP, older age, non-Caucasian race, ASA class of 3 or higher, posterior approach, previous cardiac surgery, and ostomy are independent risk factors for postoperative complications, including readmission, reoperation, and postoperative bleeding requiring transfusions. Consequently, there is a pressing need for additional research to establish perioperative strategies that reduce postoperative risks for these patients. Spine surgeons should consider the findings of this study when communicating the potential risks of spinal fusion surgery with patients and their families.

Readability Analysis of Patient Education Material on Rotator Cuff Injuries From the Top 25 Ranking Orthopaedic Institutions.

INTRODUCTION: Rotator cuff injuries (RCIs) are incredibly common in the US adult population. Forty-three percent of adults have basic or below-basic literacy levels; nonetheless, patient educational materials (PEMs) are frequently composed at levels exceeding these reading capabilities. This study investigates the readability of PEMs on RCIs published by leading US orthopaedic institutions. METHODS: The top 25 orthopaedic institutions on the 2022 U.S. News & World Report Best Hospitals Specialty Ranking were selected. Readability scores of PEMs related to RCI were calculated using the www.readabilityformulas.com website. RESULTS: Among the 25 analyzed PEM texts, all exceeded the sixth-grade reading level. Only four of 168 scores (2.4%) were below the eighth-grade level. DISCUSSION: This study indicates that PEMs on rotator cuff injuries from top orthopedic institutions are too complex for many Americans, with readability levels ranging from 8.5 to 16th grade, well above the CDC-recommended eighth-grade level. The research highlights a widespread issue with high reading levels across healthcare information and underscores the need for healthcare providers to adopt patient-centered communication strategies to improve comprehension and accessibility. CONCLUSION: PEMs on rotator cuff injuries from leading orthopedic institutions often have a reading level beyond that of many Americans, exceeding guidelines from the NIH and CDC that recommend PEMs be written at an eighth-grade reading level. To increase accessibility, enhance healthcare literacy, and improve patient outcomes, institutions should simplify these materials to meet recommended readability standards.

Predicting operative outcomes of total shoulder arthroplasty using the model for end-stage liver disease score.

Background: The aim of this study was to assess the efficacy of the Model for End-Stage Liver Disease (MELD) score in predicting postoperative complications following total shoulder arthroplasty (TSA). Methods: The American College of Surgeons National Surgical Quality Improvement database was queried for all patients who underwent TSA between 2015 and 2019. The study population was subsequently classified into two categories: those with a MELD score ≥ 10 and those with a MELD score < 10. A total of 5265 patients undergoing TSA between 2015 and 2019 were included in this study. Among these, 4690 (89.1%) patients had a MELD score ≥ 10, while 575 (10.9%) patients had a MELD score < 10. Postoperative complications within 30 days of the TSA were collected. Multivariate logistic regression analysis was conducted to explore the correlation between a MELD score ≥ 10 and postoperative complications. The anchor based optimal cutoff was calculated by receiver operating characteristic analysis to determine the MELD score cutoff that most accurately predicts a specific complication. Youden's index (J) determined the optimal cutoff point calculation for the maximum sensitivity and specificity; these were deemed to be "acceptable" if the area under curve (AUC) was greater than 0.7 and "excellent" if greater than 0.8. Results: Multivariate regression analysis found a MELD score ≥ 10 to be independently associated with higher rates of reoperation (OR, 2.08; P = .013), cardiac complications (OR, 3.37; P = .030), renal complications (OR, 7.72; P = .020), bleeding transfusions (OR, 3.23; P < .001), and nonhome discharge (OR, 1.75; P < .001). The receiver operating characteristic analysis showed that AUC for a MELD score cutoff of 7.61 as a predictor of renal complications was 0.87 (excellent) with sensitivity of 100.0% and specificity of 70.0%. AUC for a MELD score cutoff of 7.76 as a predictor of mortality was 0.76 (acceptable) with sensitivity of 81.8% and specificity of 71.0%. Conclusion: A MELD score ≥ 10 was correlated with high rates of reoperation, cardiac complications, renal complications, bleeding transfusions, and nonhome discharge following TSA. MELD score cutoffs of 7.61 and 7.76 were effective in predicting renal complications and mortality, respectively.

Cumulative effect of chronic dehydration and age on postoperative complications after total shoulder arthroplasty.

Background: Dehydration is a modifiable risk factor that should be optimized prior to all surgical procedures. The aim of this study was to determine the effects of dehydration on postoperative complications following total shoulder arthroplasty (TSA). Methods: The American College of Surgeons National Surgical Quality Improvement database was queried for all patients who underwent TSA between 2015 and 2019 and a total of 16,993 patients were included in this study. The study population was subsequently classified into 3 categories: 8498 (50.0%) nondehydrated patients with blood urea nitrogen/creatinine (BUN/Cr) < 20, 4908 (28.9%) moderately dehydrated patients with 20 ≤ BUN/Cr ≤ 25, and 3587 (21.1%) severely dehydrated patients with 25 < BUN/Cr. A subgroup analysis involving only elderly patients aged > 65 years and normalized gender-adjusted Cr values was also performed. Postoperative complications within 30 days of the TSA were collected. Multivariate logistic regression analysis was conducted to explore the correlation between dehydration and postoperative complications. Results: Adjusted multivariate logistic regression analysis showed that the severely dehydrated cohort had a greater risk of postoperative transfusion, mortality, nonhome discharge, and increased length of stay (all P < .05). The moderately dehydrated cohort had a greater risk of wound dehiscence (P = .044). Among the elderly, severely dehydrated patients had a greater risk of cardiac complications, postoperative transfusion, mortality, nonhome discharge, and increased length of stay (all P < .05). Finally, the elderly moderately dehydrated cohort had a greater risk of postoperative transfusion and nonhome discharge (all P < .05). Conclusion: BUN/Cr ratio is an important preoperative diagnostic tool to identify at-risk dehydrated patients. Providers should optimize dehydration to prevent complications, decrease costs, and improve discharge planning.

Semaglutide Use Prior to Total Hip Arthroplasty Results in Fewer Postoperative Prosthetic Joint Infections and Readmissions.

BACKGROUND: Semaglutide, a novel diabetes management medication, is known for its efficacy in inducing weight loss. Despite this, its impact on outcomes after total hip arthroplasty (THA) remains unclear. The aim of this study was to evaluate if THA patients on semaglutide demonstrate: (1) fewer medical complications; (2) fewer implant-related complications; (3) fewer readmissions; and (4) lower costs. METHODS: Using a national claims database from 2010 to 2021, we retrospectively examined diabetic patients prescribed semaglutide who underwent primary THA. This yielded 9,465 patients (Semaglutide = 1,653; Control = 7,812). Multivariable logistic regression was used to evaluate the following outcomes: 90-day postoperative medical complications, 2-year implant-related complications, 90-day readmissions, in-hospital lengths of stay, and day-of-surgery and 90-day episode of care costs. RESULTS: Semaglutide users exhibited lower 90-day readmission rates (6.2 versus 8.8%; odds ratio 0.68; P < .01) and reduced prosthetic joint infections (1.6 versus 2.9%; odds ratio 0.56; P < .01). However, medical complication rates, hospital stays, same-day surgical costs, and 90-day episode costs showed no significant differences. CONCLUSIONS: This study highlights semaglutide users undergoing THA with fewer 90-day readmissions and 2-year prosthetic joint infections. Although no variance appeared in medical complications, hospital stays, or costs, the medication's notable glycemic control and weight loss benefits could prompt pre-surgery consideration. Further research is essential for a comprehensive understanding of semaglutide's impact on post-THA outcomes.

Evaluation of readability of patient education materials on lateral epicondylitis (tennis elbow) from the top 25 orthopedic institutions.

Hypothesis: Lateral epicondylitis (LE), also known as "tennis elbow," is a common orthopedic tendinosis of the elbow that affects between 1% and 3% of the overall population. LE occurs due to overuse of the extensor mechanism or muscles of supination in the forearm. The National Institute of Health and the Center for Disease Control suggest that patient education materials (PEMs) be written at a 6th or 8th grade reading level, respectively; however, PEMs are often written far beyond these recommended reading levels. The goal of this study was to assess the readability level of PEMs published by some of the top orthopedic institutions throughout the United States. Methods: A list of the top 25 ranking orthopedic hospitals in the country was compiled using the 2022 U.S. News and World Report Best Hospitals Specialty Ranking. PEMs related to LE were cataloged from each institution's website, and readability levels for each PEM were measured using the http://www.readabilityformulas.com website. This software analyzes readability using the formulas listed in Table 1. While the Flesch-Kincaid (FK) Reading Ease Score formula outputs a number from 0 to 100, in which larger numbers indicate easier reading, the remaining formulas demonstrate a text's readability through assigning a grade-appropriate reading level. A Spearman regression was used to evaluate correlation between institutional ranking and FK Reading Ease Scores. Results: Of the 25 PEM texts analyzed during this study, none were written at or below the sixth grade reading level, as recommended by the National Institutes of Health. These results suggest that the most prestigious orthopedic hospitals provide online informational resources that are unable to be read or understood by a large portion of the institution's intended audience. Additionally, there was no correlation found between institutional ranking and FK Reading Ease Score. Conclusion: Internet-based health information has conveniently allowed patients to educate themselves on their health care. In accordance with National Institutes of Health and Centers for Disease Control and Prevention guidelines, orthopedic institutions should strive to publish PEMs at or below an eighth grade reading level.

Risk Factors of Infectious Complications in Pediatric Patients With Cerebral Palsy After Spinal Arthrodesis.

STUDY DESIGN: This was a retrospective study. OBJECTIVE: The main objective of this study was to investigate (1) whether pediatric patients with cerebral palsy (CP) have higher rates of postoperative infectious complications after spinal fusion and (2) risk factors for postoperative infections. SUMMARY OF BACKGROUND DATA: Prior studies have shown that patients with CP undergo corrective spine surgery more often than the general population, yet typically have worse postoperative outcomes. Further investigation is needed to improve our understanding of the perioperative factors that place children with CP at greater risk of postoperative infectious complications. PATIENTS AND METHODS: The 2019 "American College of Surgeons National Surgical Quality Improvement Program" Pediatric database was used for patient data. The univariable analysis compared the prevalence of preoperative comorbidities and perioperative factors between children with and without CP. Multivariable logistic regression modeling was used to ascertain independent risk factors for postoperative infectious complications. RESULTS: A total of 4445 patients were included in the study; 606 (13.63%) patients had CP and 3839 (86.37%) did not. Patients with CP were more likely to have several notable preoperative comorbidities, and the rate of developing any infectious complication was more than 7 times greater in the CP cohort than in the control cohort (14.36% vs 1.88%; P <0.001). Multivariable analysis revealed CP [odds ratio (OR): 3.55, CI: 2.25-5.60; P <0.001], American Society of Anesthesiologists class 3 or higher (OR: 2.10, CI: 1.29-3.42; P = 0.003), and hematologic disorders (OR: 2.01, CI: 1.06-3.83; P = 0.033) to be independent risk factors for increased postoperative infectious complications. CONCLUSIONS: CP is an independent risk factor for the development of 30-day postoperative infectious complications in pediatric patients. In addition, the American Society of Anesthesiologists class 3 or higher and hematologic disorders were risk factors for postoperative infections after spinal fusion surgery.
