The Effect of Written Information on Recall of Surgical Risks of Carpal Tunnel Release Surgery: A Randomized Controlled Study

Artificial Intelligence as a Consent Aid for Carpal Tunnel Release

Background Hand surgeons have been charged with the use of diverse modalities to enhance the consenting process following the Montgomery ruling. Artificial Intelligence language models have been suggested as patient education tools that may aid consent. Methods We compared the quality and readability of the Every Informed Decision Online (EIDO) patient information leaflet for carpal tunnel release with the artificial intelligence language model Chat Generative Pretrained Transformer (GPT). Results The quality of information by ChatGPT was significantly higher using the DISCERN score, 71/80 for ChatGPT compared to 62/80 for EIDO (p=0.014). DISCERN interrater observer reliability was high (0.65) using the kappa statistic. Flesch-Kincaid readability scoring was 12.3 for ChatGPT and 7.5 for EIDO, suggesting a more complex reading age for the ChatGPT information. Conclusion The artificial intelligence language model ChatGPT produces high-quality information at the expense of readability when compared to EIDO information leaflets for carpal tunnel release consent.

"Spin" in Plastic Surgery Randomized Controlled Trials with Statistically Nonsignificant Primary Outcomes: A Systematic Review

BACKGROUND

"Spin" refers to a manipulation of language that implies benefit for an intervention when none may exist. Randomized controlled trials (RCTs) in other fields have been demonstrated to employ spin, which can mislead clinicians to use ineffective or unsafe interventions. This study's objective was to determine the strategies, severity, and extent of spin in plastic surgery RCTs with nonsignificant primary outcomes.

METHODS

A literature search of the top 15 plastic surgery journals using MEDLINE was performed (2000 through 2020). Parallel 1:1 RCTs with a clearly identified primary outcome showing statistically nonsignificant results ( P > 0.05) were included. Screening, data extraction, and spin analysis were performed by two independent reviewers. The spin analysis was then independently assessed in duplicate by two plastic surgery residents with graduate-level training in clinical epidemiology.

RESULTS

From 3497 studies identified, 92 RCTs were included in this study. Spin strategies were identified in 78 RCTs (85%), including 64 abstracts (70%) and 77 main texts (84%). Severity of spin was rated moderate or high in 43 abstract conclusions (47%) and 42 main text conclusions (46%). The most identified spin strategy in the abstract was claiming equivalence for statistically nonsignificant results (26%); in the main text, focusing on another objective (24%).

CONCLUSIONS

This study suggests that 85% of statistically nonsignificant RCTs in plastic surgery employ spin. Readers of plastic surgery research should be aware of strategies, whether intentional or unintentional, used to manipulate language in reports of statistically nonsignificant RCTs when applying research findings to clinical practice.

A randomized controlled trial of patient recall after detailed written consent versus standard verbal consent in adults with routine orthopaedic trauma

Patient decision aids have previously demonstrated an improvement in the quality of the informed consent process. This study assessed the effectiveness of detailed written patient information, compared to standard verbal consent, in improving postoperative recall in adult orthopaedic trauma patients. This randomized controlled feasibility trial was conducted at two teaching hospitals within the South Eastern Sydney Local Health District. Adult patients (age ≥ 18 years) pending orthopaedic trauma surgery between March 2021 and September 2021 were recruited and randomized to detailed or standard methods of informed consent using a random sequence concealed in sealed, opaque envelopes. The detailed group received procedure-specific written information in addition to the standard verbal consent. The primary outcome was total recall, using a seven-point interview-administered recall questionnaire at 72 hours postoperatively. Points were awarded if the participant correctly recalled details of potential complications (maximum three points), implants used (maximum three points), and postoperative instructions (maximum one point). Secondary outcomes included the anxiety subscale of the Hospital and Anxiety Depression Scale (HADS-A) and visual analogue scale (VAS) for pain collected at 24 hours preoperatively and 72 hours postoperatively. Additionally, the Patient Satisfaction Questionnaire Short Form (PSQ-18) measured satisfaction at 72 hours postoperatively. A total of 60 patients were randomized, 32 to the standard group and 28 to the detailed group. Patients in the detailed group had significantly higher total recall score compared to the standard group (mean difference 1.29 points (95% confidence interval (CI) 0.51 to 2.08); p = 0.002). There were no differences in HADS-A (mean difference 0.39 (95% CI -2.11 to 2.88); p = 0.757), VAS pain (mean difference 5.71 (95% CI -22.25 to 11.11); p = 0.499), or PSQ-18 (mean difference 0.499; 95% CI -1.6 to 3.42; p = 0.392). Detailed written tools are useful in improving postoperative recall in adult orthopaedic trauma patients.

Utilizing the "teach-back" method to improve surgical informed consent and shared decision-making: a review

The teach-back method is a valuable communication tool that can be employed to improve patient safety and shared decision-making. Its utility in patient care has been studied extensively in many areas of clinical medicine. However, the literature on the use of teach-back in surgical patient education and informed consent is limited. Additionally, there is some ambiguity about the functional definition and performance of the teach-back method in the literature, consequently rendering this valuable tool an enigma. This review examines the current standards and ethics of preoperative informed consent and provides a concise, actionable definition of teach-back. The manner in which teach-back has been implemented in medicine and surgery is then examined in detail. Studies analyzing the use of teach-back in medicine have demonstrated its effectiveness and benefit to patient care. Further study on the use of teach-back to improve preoperative informed consent is supported by the few preliminary trials showing a positive effect after implementing the teach-back method in critical patient interactions.

Influence of a Preadmission Procedure-Specific Consent Document on Patient Recall of Informed Consent at 4 Weeks After Total Hip Replacement: A Randomized Controlled Trial

OBJECTIVES

Consent is a legal and ethical requirement for undertaking surgical procedures; however, the literature suggests that there continues to be poor recall among patients of the surgical risks discussed during the consent process. The aim of this study was to evaluate whether the addition of a preadmission procedure-specific consent document would improve patient recall of surgical risks at 4 weeks after total hip replacement in patients consented with a procedure-specific consent form.

METHODS

A prospective randomized controlled trial allocated seventy adult patients who were undergoing a primary total hip replacement to either receive (intervention group) or not receive (control group) a preadmission procedure-specific consent document. All patients were also consented with a procedure-specific consent form on the morning of surgery and were contacted 4 weeks later to assess recall of surgical risks.

RESULTS

There was a very poor recall rate seen in both the intervention group (16%) and the control group (13%), with no statistically significant difference between them (P = 0.49). A large number (30%) of patients could not recall a single risk. A subgroup analysis excluding these "consent nonresponders" did show a significantly increased recall rate in the intervention group (24.5% versus 18.25%, P = 0.02).

CONCLUSIONS

Patient recall of potential complications of total hip replacement was poor despite the intervention. Although not effective overall, the use of a preadmission procedure-specific consent document did improve recall of potential complications of surgery in a subset of patients. The phenomenon of consent nonresponders is worth exploring in future research.

Improving Surgical Informed Consent: Unanswered Questions

Objective

This study reviews randomized clinical trials that have attempted to improve the process of informed consent. Consent should be guided by the ethical imperatives of autonomy, beneficence, and social justice.

Summary Background

Informed consent is constantly evolving. Yet our review of the randomized trials done to improve the surgical informed consent process raises a number of questions: How does one define surgical informed consent? What interventions have been tried to measure and improve informed consent? Have the interventions in informed consent actually led to improvements? What efforts have been made to improve informed consent? And what steps can be taken to improve the process further?

Methods

A literature search for randomized controlled trials (RCTs)on informed consent identified 70 trials. Demographics, interventions, assessments, and a semi-quantitative summary of the findings were tabulated. The assessments done in the RCTs, show the surrogate for patient autonomy was comprehension; for beneficence, satisfaction and mental state (anxiety or depression); and, for social justice, language, literacy, learning needs, and cost.

Results

There were 4 basic categories of interventions: printed matter; non-interactive audiovisual tools; interactive multimedia; and a smaller group defying easy description. Improvement was documented in 46 of the 65 trials that studied comprehension. Thirteen of 33 trials showed improved satisfaction. Three of 30 studies showed an increase in anxiety. Few studies tried to assess primary language or literacy, and none looked at learning needs or cost.

Conclusions

No single study improved all 3 principles of informed consent. Validated interventions and assessments were associated with greater impact on outcomes. All 3 ethical principles should be assessed; autonomy (as comprehension), beneficence (as satisfaction, anxiety), and social justice. Not enough consideration has been given to social justice; appropriate language translation, standardized reading levels, assessment of learning needs, and cost to the individual are all important elements worthy of future study.

Interventions to Improve Patient Comprehension in Informed Consent for Medical and Surgical Procedures: An Updated Systematic Review

Background. Patient comprehension is fundamental to valid informed consent. Current practices often result in inadequate patient comprehension. Purpose. An updated review to evaluate the characteristics and outcomes of interventions to improve patient comprehension in clinical informed consent. Data Sources. Systematic searches of MEDLINE and EMBASE (2008-2018). Study Selection. We included randomized and nonrandomized controlled trials evaluating interventions to improve patient comprehension in clinical informed consent. Data Extraction. Reviewers independently abstracted data using a standardized form, comparing all results and resolving disagreements by consensus. Data Synthesis. Fifty-two studies of 60 interventions met inclusion criteria. Compared with standard informed consent, a statistically significant improvement in patient comprehension was seen with 43% (6/14) of written interventions, 56% (15/27) of audiovisual interventions, 67% (2/3) of multicomponent interventions, 85% (11/13) of interactive digital interventions, and 100% (3/3) of verbal discussion with test/feedback or teach-back interventions. Eighty-five percent of studies (44/52) evaluated patients' understanding of risks, 69% (41/52) general knowledge about the procedure, 35% (18/52) understanding of benefits, and 31% (16/52) understanding of alternatives. Participants' education level was reported heterogeneously, and only 8% (4/52) of studies examined effects according to health literacy. Most studies (79%, 41/52) did not specify participants' race/ethnicity. Limitations. Variation in interventions and outcome measures precluded conduct of a meta-analysis or calculation of mean effect size. Control group processes were variable and inconsistently characterized. Nearly half of studies (44%, 23/52) had a high risk of bias for the patient comprehension outcome. Conclusions. Interventions to improve patient comprehension in informed consent are heterogeneous. Interactive interventions, particularly with test/feedback or teach-back components, appear superior. Future research should emphasize all key elements of informed consent and explore effects among vulnerable populations.

The Effect of Written Information on Recall of Surgical Risks of Primary Cleft Palate Repair: A Randomized Controlled Study

OBJECTIVE

To investigate parents' understanding of the risks of primary cleft palate surgery after counseling with and without the use of a written informational aid.

DESIGN

Prospective, randomized, single-blind trial.

SETTING

Academic tertiary care center.

PARTICIPANTS

Parents of children undergoing primary cleft palate surgery.

INTERVENTIONS

Parents were randomized to receive a standard informed consent discussion with or without provision of a written informational aid in the form of a pamphlet.

MAIN OUTCOMES MEASURE

Parents' recall of 9 specific surgical risks 3 weeks after informed consent discussion.

RESULTS

Forty parents enrolled in and completed the study (20 participants each in the control and intervention groups). There were no statistically significant differences between groups in terms of baseline demographics. The mean number of risks recalled were 3.7 (1.6) for the control group and 4.2 (1.9) for the intervention group (P = .37). The most commonly recalled risks were fistula formation and bleeding, while the least frequent were facial growth restriction and need for further surgery. No differences in risk recall were observed based on participant's gender, level of education, or income.

CONCLUSION

Parents of children undergoing primary cleft palate surgery recall less than 50% of counseled risks. The use of a written aid in the form of a pamphlet did not significantly improve recall in this sample. These results demonstrate that surgeons should implement additional measures to improve comprehension of surgical risks.

Variables That Impact Medical Malpractice Claims Involving Plastic Surgeons in the United States

BACKGROUND

Medical malpractice lawsuits contribute directly and indirectly to the cost of healthcare in the United States. Reducing medical malpractice claims represents an often unrecognized opportunity for improving both the quality and affordability of healthcare.

OBJECTIVES

The aim of this study was to better understand variables of the informed consent process that may contribute to reducing malpractice claims in plastic surgery.

METHODS

A prospective multiple choice questionnaire was distributed via email to all of the 1694 members of the American Society for Aesthetic Plastic Surgery (ASAPS) to evaluate attitudes and practices of informed consent in relation to medical malpractice.

RESULTS

A total of 129 questionnaires obtained from plastic surgeons were eligible for analysis (response rate 7.6%). Respondents who provided procedure-specific brochures to their patients were significantly less likely to be sued for medical malpractice (P = 0.004) than those who did not. Plastic surgeons that participated in malpractice carrier-required courses on avoiding medical malpractice litigation had a similarly significantly reduced likelihood of lawsuits. (P = 0.04).

CONCLUSIONS

Variables that may reduce malpractice claims, and thereby both improve the quality and affordability of healthcare, include: (1) the use of procedure-specific patient education brochures; and (2) physician participation in malpractice insurance carrier-required courses. These findings should be of interest to physicians, hospitals, and insurance companies.

The efficacy of mobile application use on recall of surgical risks in nasal bone fracture reduction surgery

Background

The number of surgical risks recalled by a patient after surgery can be used as a parameter for assessing how well the patient has understood the informed consent process. No study has investigated the usefulness of a self-developed mobile application in the traditional informed consent process in patients with a nasal bone fracture. This study aimed to investigate whether delivery of information, such as surgical risks, through a mobile application is more effective than delivery of information through only verbal means and a paper.

Methods

This prospective, randomized study included 60 patients with a nasal bone fracture. The experimental group (n=30) received preoperative explanation with the traditional informed consent process in addition to a mobile application, while the control group (n=30) received preoperative explanation with only the traditional informed consent process. Four weeks after surgery, the number of recalled surgical risks was compared for analysis. The following six surgical risks were explained: pain, bleeding, nasal deformity, numbness, nasal obstruction, and nasal cartilage necrosis.

Results

The mean number of recalled surgical risks among all patients was 1.58±0.56. The most frequently recalled surgical risk was nasal deformity in both groups. The mean number of recalled surgical risks was 1.72±0.52 in the experimental group and 1.49±0.57 in the control group. There was a significant association between mobile application use and the mean number of recalled surgical risks (p=0.047). Age, sex, and the level of education were not significantly associated with the mean number of recalled surgical risks.

Conclusion

This study found that a mobile application could contribute to the efficient delivery of information during the informed consent process. With further improvement, it could be used in other plastic surgeries and other surgeries, and such an application can potentially be used for explaining risks as well as delivering other types of information.
