The Impact of Using Electronic Consents on Documentation of Language-Concordant Surgical Consent for Patients with Limited English Proficiency.

BACKGROUND: Although access to a professional medical interpreter is federally mandated, surgeons report underutilization during informed consent. Improvement requires understanding the extent of the lapses. Adoption of electronic consent (eConsent) has been associated with improvements in documentation and identification of practice improvement opportunities. The authors evaluated the impact of the transition from paper to eConsent on language-concordant surgical consent delivery for patients with limited English proficiency (LEP). METHODS: The study period (February 8, 2023, to June 14, 2023) corresponds to the period immediately following the institutional adoption of eConsents. Inclusion criteria included age > 18 years, documented preferred language other than English, and self-signed eConsent form. The authors assessed documentation of language-concordant interpreter-mediated verbal consent discussion and delivery of the written surgical consent form in a language-concordant template. Performance was compared to a preimplementation baseline derived from monthly random audits of paper consents between January and December 2022. RESULTS: A total of 1,016 eConsent encounters for patients with LEP were included, with patients speaking 49 different languages, most commonly Spanish (46.5%), Chinese (22.1%), and Russian (6.8%). After the implementation of eConsent, overall documentation of language-concordant interpreter-mediated consents increased from 56.9% to 83.9% (p < 0.001), although there was variation between surgical services and between languages, suggesting that there is still likely room for improvement. Most patients (94.1%) whose preferred language had an associated translated written consent template (Spanish, Chinese, Russian, Arabic), received a language-concordant written consent. CONCLUSION: The transition to eConsent was associated with improved documentation of language-concordant informed consent in surgery, both in terms of providing written materials in the patient's preferred language and in the documentation of interpreter use, and allowed for the identification of areas to target for practice improvement with interpreter use.

Large Language Model-Based Chatbot vs Surgeon-Generated Informed Consent Documentation for Common Procedures.

Importance: Informed consent is a critical component of patient care before invasive procedures, yet it is frequently inadequate. Electronic consent forms have the potential to facilitate patient comprehension if they provide information that is readable, accurate, and complete; it is not known if large language model (LLM)-based chatbots may improve informed consent documentation by generating accurate and complete information that is easily understood by patients. Objective: To compare the readability, accuracy, and completeness of LLM-based chatbot- vs surgeon-generated information on the risks, benefits, and alternatives (RBAs) of common surgical procedures. Design, Setting, and Participants: This cross-sectional study compared randomly selected surgeon-generated RBAs used in signed electronic consent forms at an academic referral center in San Francisco with LLM-based chatbot-generated (ChatGPT-3.5, OpenAI) RBAs for 6 surgical procedures (colectomy, coronary artery bypass graft, laparoscopic cholecystectomy, inguinal hernia repair, knee arthroplasty, and spinal fusion). Main Outcomes and Measures: Readability was measured using previously validated scales (Flesh-Kincaid grade level, Gunning Fog index, the Simple Measure of Gobbledygook, and the Coleman-Liau index). Scores range from 0 to greater than 20 to indicate the years of education required to understand a text. Accuracy and completeness were assessed using a rubric developed with recommendations from LeapFrog, the Joint Commission, and the American College of Surgeons. Both composite and RBA subgroup scores were compared. Results: The total sample consisted of 36 RBAs, with 1 RBA generated by the LLM-based chatbot and 5 RBAs generated by a surgeon for each of the 6 surgical procedures. The mean (SD) readability score for the LLM-based chatbot RBAs was 12.9 (2.0) vs 15.7 (4.0) for surgeon-generated RBAs (P = .10). The mean (SD) composite completeness and accuracy score was lower for surgeons' RBAs at 1.6 (0.5) than for LLM-based chatbot RBAs at 2.2 (0.4) (P < .001). The LLM-based chatbot scores were higher than the surgeon-generated scores for descriptions of the benefits of surgery (2.3 [0.7] vs 1.4 [0.7]; P < .001) and alternatives to surgery (2.7 [0.5] vs 1.4 [0.7]; P < .001). There was no significant difference in chatbot vs surgeon RBA scores for risks of surgery (1.7 [0.5] vs 1.7 [0.4]; P = .38). Conclusions and Relevance: The findings of this cross-sectional study suggest that despite not being perfect, LLM-based chatbots have the potential to enhance informed consent documentation. If an LLM were embedded in electronic health records in a manner compliant with the Health Insurance Portability and Accountability Act, it could be used to provide personalized risk information while easing documentation burden for physicians.

Using Electronic Health Record Meta-Data to Identify Variation in Trainee Progress Note Writing Patterns: Opportunity to Enhance Systems-Based Care.

OBJECTIVE: Daily progress notes are the backbone of all inpatient hospitalizations. Progress notes serve as a lasting record of a patient's diagnoses, condition, and planned interventions and are essential communication tools. We designed a study to identify patterns in progress note filing and use on general surgical services. METHODS: The electronic health record (EHR) data warehouse was queried for general surgical progress notes signed between July 1, 2020, and July 1, 2021. Only notes authored by resident physicians or advanced practice providers (APPs) were included, and those filed on the day of a surgery were excluded. 10 am was identified as a target for note completion as it coincided with multidisciplinary discharge rounds. Physician, case managers pharmacist, physical therapist, dietician, nurse (and collaborating disciplines) progress note views were measured using EHR access log data. RESULTS: A total of 8384 progress notes were analyzed; 4146 notes (49%) were authored by 81 trainees. A total of 4433 (53%) progress notes were filed before 10 am, 3673 (44%) were filed between 10 am and 6 pm, and 278 (3%) were filed after 6 pm. Variation in progress note file time was observed and associated with individual habits, residents vs APPs, day-of-week, and service structure. Surgery progress notes are viewed by collaborating disciplines throughout the workday, with high-volume viewership occurring by mid-morning. Each individual progress note received an average of 17.6 lifetime views with a range of 1 to 76. An average of 10.2 of those views occurred on the same day that the note was written. Notes that were filed after 10 am received a significantly lower number of same-day views compared to notes filed before 10am (8.4 vs 11.8, p < 0.0001). CONCLUSIONS: Progress notes are identified as a significant burden by trainees and even considered to contribute to duty hour violations, yet they are used regularly as a source of information for collaborating disciplines. Progress notes filed earlier are viewed more frequently. Efforts to identify barriers to timeliness may help communication and efficiency of inpatient surgical care.

Assessing the role of robotic proctectomy in obese patients: a contemporary NSQIP analysis.

Robotic proctectomy has become increasingly popular for both benign and malignant indications. The purpose of this study was to determine if the robotic approach has a distinct advantage over laparoscopy in obese patients, which has been suggested by previous subgroup analyses. We performed a retrospective review of 2016-2018 National Surgery Quality Improvement Program (NSQIP) data to compare outcomes between patients who underwent robotic versus laparoscopic proctectomy, stratified by Body Mass Index (BMI) subgroups. We also compared outcomes of converted minimally invasive proctectomy to planned open operations. Four thousand four hundred eighteen (69.3%) patients underwent laparoscopic proctectomy, and 1956 (30.7%) patients underwent robotic proctectomy. Robotic proctectomy was associated with a significantly lower conversion rate compared to laparoscopic proctectomy (5.1% vs 12.3%; p = 0.002), and this relationship was maintained on an adjusted model. Obese (BMI > 30) patients were more likely to require conversion in both laparoscopic and robotic groups with the greatest difference in the conversion rate in the obese subgroup. Patients who underwent conversion had higher composite morbidity compared to patients who underwent planned open operations (50.8% vs 41.3%; p < 0.001). And among patients with rectal cancer, robotic proctectomy was associated with a greater incidence of positive radial tumor margins compared to laparoscopic proctectomy (8.0% vs 6.4%; p = 0.039), driven primarily by the obese subgroup. Our study demonstrates that robotic proctectomy is associated with a 7% lower conversion rate compared to laparoscopy and that obese patients are more likely to require conversion than non-obese patients. Among obese patients with rectal cancer, we identified an increased risk of positive radial margins with robotic compared to laparoscopic proctectomy.

MicroRNAs are Necessary for BMP-7-induced Dendritic Growth in Cultured Rat Sympathetic Neurons.

Neuronal connectivity is dependent on size and shape of the dendritic arbor. However, mechanisms controlling dendritic arborization, especially in the peripheral nervous system, are not completely understood. Previous studies have shown that bone morphogenetic proteins (BMPs) are important initiators of dendritic growth in peripheral neurons. In this study, we examined the hypothesis that post-transcriptional regulation mediated by microRNAs (miRNAs) is necessary for BMP-7-induced dendritic growth in these neurons. To examine the role of miRNAs in BMP-7-induced dendritic growth, microarray analyses was used to profile miRNA expression in cultured sympathetic neurons from the superior cervical ganglia of embryonic day 21 rat pups at 6 and 24 h after treatment with BMP-7 (50 ng/mL). Our data showed that BMP-7 significantly regulated the expression of 43 of the 762 miRNAs. Of the 43 miRNAs, 22 showed robust gene expression; 14 were upregulated by BMP-7 and 8 were downregulated by BMP-7. The expression profile for miR-335, miR-664-1*, miR-21, and miR-23b was confirmed using qPCR analyses. Functional studies using morphometric analyses of dendritic growth in cultured sympathetic neurons transfected with miRNA mimics and inhibitors indicated that miR-664-1*, miR-23b, and miR-21 regulated early stages of BMP-7-induced dendritic growth. In summary, our data provide evidence for miRNA-mediated post-transcriptional regulation as important downstream component of BMP-7 signaling during early stages of dendritic growth in sympathetic neurons.

Long-term outcomes after repair of symptomatic abdominal aortic aneurysms.

OBJECTIVES: Previous studies have reported increased perioperative mortality of nonruptured symptomatic abdominal aortic aneurysms (Sx-AAA) compared with asymptomatic elective AAA (E-AAA) repairs, but no long-term-outcomes have been reported. We sought to compare long-term outcomes of Sx-AAA and E-AAA after repair at a single academic institution. METHODS: Patients receiving AAA repair for Sx-AAA and E-AAA from 1995 through 2015 were included. Ruptured AAA and suprarenal or thoracoabdominal AAA were excluded. Demographics, comorbidities, and operative approach were collected. Long-term mortality was the primary outcome, determined by chart review or link to Social Security Death Index. Additionally, long-term mortality and reinterventions were compared after groups were matched with nearest neighbor propensity to reduce bias. RESULTS: AAA repair was performed for 1054 E-AAA (383 open repair [36%], 671 endovascular aneurysm repair [EVAR] [64%]), and 139 symptomatic aneurysms (60 open repair [43%], 79 EVAR [57%]). Age (73 years vs 74 years; P = .13) and aneurysm diameter were similar between Sx-AAA and E-AAA (6.0 cm vs 5.8 cm; P = .5). The proportion of women was higher for Sx-AAA (26% vs 16%; P = .003), as was the proportion of non-Caucasians (40% vs 29%; P = .009). After propensity matching, there were no differences between groups for patient characteristics, AAA diameter, treatment modality, or comorbidities, including hypertension, coronary artery disease, congestive heart failure, diabetes, hyperlipidemia, lung disease, diabetes, renal disease, and smoking history. Women were treated for Sx-AAA at significantly smaller aortic diameters; however, compared with men (5.1 cm vs 6.3 cm; P < .001). Perioperative mortality was 5.0% for Sx-AAA and 2.3% for E-AAA (P = .055). By life-table analysis, Sx-AAA had lower 5-year (62% vs 71%) and 10-year (39% vs 51%) survivals (P = .01) compared with E-AAA for the entire cohort. Similar trends were observed for 5-year and 10-year mortality after propensity matching (63% and 40% vs 71% and 52%; P = .05). When stratified by repair type 5-year and 10-year survivals trended lower after open surgery (68% and 42% Sx-AAA vs 84% and 59% E-AAA; P = .08) but not EVAR (59% and 40% Sx-AAA vs 61% and 49% E-AAA; P = .4). Aneurysm-related reinterventions were similar for Sx-AAA and E-AAA (15% vs 14%; P = .8). Reinterventions were more common after EVAR compared with open repair (22% vs 7%, Sx-AAA P = .015; 20% vs 4% E-AAA; P = .007). CONCLUSIONS: Patients with Sx-AAA had lower long-term survival and similar aneurysm-related reinterventions compared with patients with E-AAA undergoing repair. Women also underwent repair for Sx-AAA at a significantly smaller size when compared with men, which emphasizes the role of gender in AAA symptomatology. Differences in long-term survival may be only partially explained by measured patient, aneurysm, and operative factors, and may reflect unmeasured social factors or suggest inherent differences in pathophysiology of Sx-AAAs.

Video-Based Learning vs Traditional Lecture for Instructing Emergency Medicine Residents in Disaster Medicine Principles of Mass Triage, Decontamination, and Personal Protective Equipment.

Introduction Great demands have been placed on disaster medicine educators. There is a need to develop innovative methods to educate Emergency Physicians in the ever-expanding body of disaster medicine knowledge. The authors sought to demonstrate that video-based learning (VBL) could be a promising alternative to traditional learning methods for teaching disaster medicine core competencies. Hypothesis/Problem The objective was to compare VBL to traditional lecture (TL) for instructing Emergency Medicine residents in the American College of Emergency Physicians (ACEP; Irving, Texas USA) disaster medicine core competencies of patient triage and decontamination. METHODS: A randomized, controlled pilot study compared two methods of instruction for mass triage, decontamination, and personal protective equipment (PPE). Emergency Medicine resident learning was measured with a knowledge quiz, a Likert scale measuring comfort, and a practical exercise. An independent samples t-test compared the scoring of the VBL with the TL group. RESULTS: Twenty-six residents were randomized to VBL (n=13) or TL (n=13). Knowledge score improvement following video (14.9%) versus lecture (14.1%) did not differ significantly between the groups (P=.74). Comfort score improvement also did not differ (P=.64) between video (18.3%) and lecture groups (15.8%). In the practical skills assessment, the VBL group outperformed the TL group overall (70.4% vs 55.5%; P<.0001), with significantly better performance in donning PPE and decontamination. Although not part of the original study design, a three-month post-hoc analysis was performed. When comparing the pre-intervention and three-month post-hoc performances, there were no significant differences in knowledge increases between VBL versus TL (P=.41) or in comfort (P=.39). CONCLUSION: Video modules can be as effective as TL when utilized to train Emergency Medicine residents in the ACEP disaster medicine core competencies of patient triage and decontamination.

Management and outcomes of symptomatic abdominal aortic aneurysms during the past 20 years.

OBJECTIVE: We compared the management of patients with symptomatic, unruptured abdominal aortic aneurysms (AAAs) treated at a tertiary care center between two decades. This 20-year period encapsulated a shift in surgical approach to aortic aneurysms from primarily open to primarily endovascular, and we sought to determine the effect of this shift in the evaluation, treatment, and clinical outcomes of patients with symptomatic AAA. METHODS: We reviewed 1429 consecutive patients with unruptured AAAs treated at a tertiary care hospital by six staff surgeons between 1995 and 2004 (era 1) and between 2005 and 2014 (era 2). Of those patients, 160 (11%) were symptomatic from their aneurysm and were included in our study. Patient demographics, operative approach, and outcomes were analyzed and compared for each period. RESULTS: Era 1 included 75 patients (71% men; average age, 73.1 ± 10.0 years) treated for symptomatic AAA (91.9% infrarenal, 4.0% juxtarenal, and 4.0% pararenal); of these, 68% were treated with open repair and 32.0% were treated with an endovascular repair. Perioperative mortality during this period was 5.3% (7.8% for the open cohort and 0% for the endovascular cohort). Era 2 included 85 patients (72.9% men; average age 72.0 ± 9.5 years) treated for symptomatic AAA (90.1% infrarenal, 7.5% juxtarenal, and 2.4% pararenal); of these, 29% were treated open and 71% underwent endovascular repair. Perioperative mortality was 5.9% (8.0% for the open cohort and 5.0% for the endovascular cohort). Era 2 had a significantly higher rate of endovascular repair compared with era 1 (71% vs 32%; P < .0001) and a trend toward decreased long-term mortality. The length of stay for era 2 was significantly reduced compared with era 1 (4 days vs 6 days; P = .005). CONCLUSIONS: To our knowledge, this is the largest single-institution cohort of symptomatic AAAs, which comprise 10% to 11% of overall aneurysms. As expected, we found a significant shift over time in the approach to these patients from a primarily open to a primarily endovascular technique. The modern era was also associated with decreased lengths of stay and fewer gastrointestinal and wound complications but no significant differences in overall perioperative mortality.

Relative mRNA Expression Levels of Restriction Factors and Antiviral Genes in Fetal and Adult Human Monocytes and Monocyte-Derived Macrophages.

Among untreated HIV-infected pregnant women, the frequency of mother-to-child transmission of HIV is low (5-10%), with most infections occurring at or after birth. Given findings that fetal and adult monocytes are distinct from one another in terms of basal transcriptional profiles, and in phosphorylation of signal transducer and activators of transcription in response to cytokines, we hypothesized that fetal CD14+CD16- monocyte and monocyte-derived macrophages (MDMs) might, compared to their adult counterparts, express higher levels of transcripts for restriction factors and antiviral factors at baseline and/or after stimulation with cytokines that might be induced upon transmission of HIV in utero, for example, IFNα, IFNγ, and IL-6. We carried out these experiments and noted that a few genes, including APOBEC3B, APOBEC3C, and IFITM2, were expressed to a greater degree in fetal monocytes compared to adults. Similarly, the expression levels of APOBEC3F and TRIM32 were greater in fetal MDMs. However, most of these differences were not observed after stimulation with cytokines and the vast majority of antiviral genes were more highly expressed in adults. Therefore, the results of this study are not consistent with the hypothesis that increased expression of antiviral genes in fetal myeloid cells confers immune protection to fetuses in utero.
