Promoting Surgical Resident Well-being Through Therapist-Facilitated Discussion Groups: A Quantitative and Qualitative Analysis.

OBJECTIVE: To improve the well-being and sense of community of surgical trainees. DESIGN: Residents were invited to participate in confidential discussion groups during protected education time to have a safe space to support each other through common struggles. The groups were facilitated by licensed mental health professionals with experience working with medical trainees. An anonymous voluntary wellness survey and a qualitative feedback survey were used to understand residents' experience participating in these discussion groups. SETTING: Single large academic institution. PARTICIPANTS: General surgery and obstetrics and gynecology residents. RESULTS: 677 resident responses to the wellness survey were collected between 2020 and 2023. Compared to residents who participated in < 5 discussion group sessions, residents participating in ≥ 5 sessions reported improved self-perception of their own competency and capability (p = 0.012), and in their ability to contribute to others' well-being (p = 0.045). They also reported considering more of their co-residents as friends (p = 0.002), increased willingness to discuss personal problems with their co-residents (p < 0.001), and were more likely to report recently working with peers to solve a common problem (p = 0.041). In a second qualitative survey (n = 53), resident feedback revealed an appreciation for the opportunity to discuss shared experiences, creating community, having a safe space and dedicated time for introspection, and receiving input from a therapist. Opportunities for improvement included providing more structure to the discussion, increasing the frequency of group meetings, and focusing on developing coping skills. CONCLUSION: Therapist-facilitated discussion groups can improve aspects of trainees' mental well-being and help foster relatedness, community, and shared problem solving with peers. Residency programs should consider incorporating similar programs into their wellness initiatives.

Is it gossip or feedback? Surgical attendings' perceptions of gossip within residency.

OBJECTIVE: Gossip-evaluative talk about an absent third party-exists in surgical residency programs. Attending surgeons may engage in gossip to provide residents with feedback on performance, which may contribute to bias. Nevertheless, the perspectives of attending surgeons on gossip has not been studied. DESIGN: In this qualitative study, semi-structured interviews about gossip in surgical training were conducted with attending surgeons. We performed a reflexive thematic analysis of transcripts with a grounded theory approach to describe attendings' perceptions of their role in gossip within surgical residency. SETTING: Interviews were conducted from September 23, 2023, to November 27, 2023 via Zoom™. PARTICIPANTS: Eighteen surgery attendings associated with 7 surgical training programs were interviewed. RESULTS: Six themes were developed: 1) Attendings typically view gossip with a negative lens; thus, well-intended conversations about resident performance that meet the academic definition of gossip are not perceived as gossip; 2) Gossip can damage attendings' reputations as surgeons and educators; 3) Mitigating the negative impacts of gossip by maintaining accurate and objective standards of honest communication is hard; 4) Attendings express concerns about hearing other attendings' impressions of residents prior to formulating their own opinion; 5) The surgical hierarchy restricts the volume and content of gossip that reaches attendings, which may limit their knowledge of program culture; and 6) It is very difficult to mitigate gossip at the program level. Ultimately, attendings utilize gossip (e.g. triangulating their experience) with the goal of providing residents feedback. CONCLUSIONS: Defining important conversations about resident performance as gossip should not discourage these critically important conversations but rather underscore the importance of combating harmful gossip through 3 behaviors: 1) committing to objective communication; 2) limiting or reframing information about resident performance that is shared with attendings who have yet to formulate their own opinions; and 3) regulating gossip in particular high-stakes microenvironments (e.g. the operating room).

A Randomized Crossover Trial Evaluating the Impact of Cultural Dexterity Training on Surgical Residents' Knowledge, Cross-Cultural Care, Skills, and Beliefs: The Provider Awareness and Cultural Dexterity Training for Surgeons (PACTS) Trial.

OBJECTIVES: This trial examines the impact of the Provider Awareness and Cultural dexterity Toolkit for Surgeons (PACTS) curriculum on surgical residents' knowledge, cross-cultural care, skills, and beliefs. BACKGROUND: Cross-cultural training of providers may reduce health care outcome disparities, but its effectiveness in surgical trainees is unknown. METHODS: PACTS focuses on developing skills needed for building trust, working with patients with limited English proficiency, optimizing informed consent, and managing pain. The PACTS trial was a randomized crossover trial of 8 academic general surgery programs in the United States: The Early group ("Early") received PACTS between periods 1 and 2, while the Delayed group ("Delayed") received PACTS between periods 2 and 3. Residents were assessed preintervention and postintervention on Knowledge, Cross-Cultural Care, Self-Assessed Skills, and Beliefs. χ 2 and Fisher exact tests were conducted to evaluate within-intervention and between-intervention group differences. RESULTS: Of 406 residents enrolled, 315 were exposed to the complete PACTS curriculum. Early residents' Cross-Cultural Care (79.6%-88.2%, P <0.0001), Self-Assessed Skills (74.5%--85.0%, P <0.0001), and Beliefs (89.6%-92.4%, P =0.0028) improved after PACTS; knowledge scores (71.3%-74.3%, P =0.0661) were unchanged. Delayed resident scores pre-PACTS to post-PACTS showed minimal improvements in all domains. When comparing the 2 groups in period 2, Early residents had modest improvement in all 4 assessment areas, with a statistically significant increase in Beliefs (92.4% vs 89.9%, P =0.0199). CONCLUSIONS: The PACTS curriculum is a comprehensive tool that improved surgical residents' knowledge, preparedness, skills, and beliefs, which will help with caring for diverse patient populations.

Race and Odds of Surgery Offer in Small Bowel and Pancreas Neuroendocrine Neoplasms.

BACKGROUND: Despite existing society guidelines, management of pancreatic (PanNEN) and small bowel (SBNEN) neuroendocrine neoplasms remains inconsistent. The purpose of this study was to identify patient- and/or disease-specific characteristics associated with increased odds of being offered surgery for PanNEN and SBNEN. PATIENTS AND METHODS: The Surveillance, Epidemiology, and End Results (SEER) Program database and the National Cancer Database (NCDB) were queried for patients with PanNEN/SBNEN. Demographic and pathologic data were compared between patients who were offered surgery and those who were not. Multivariate logistic regression was performed to identify factors independently associated with being offered surgery. RESULTS: In SEER, there were 3641 patients with PanNEN (54.7% were offered surgery) and 5720 with SBNEN (86.0% were offered surgery). On multivariate analysis of SEER, non-white race was associated with decreased odds of surgery offer for SBNEN [odds ratio (OR) 0.58, p < 0.001], but not PanNEN (p = 0.187). In NCDB, there were 28,483 patients with PanNEN (57.5% were offered surgery) and 42,675 with SBNEN (86.9% were offered surgery). On multivariate analysis of NCDB, non-white race was also associated with decreased odds of surgery offer for SBNEN (OR 0.61, p < 0.001) but not PanNEN (p = 0.414). CONCLUSIONS: This study's findings suggest that, in addition to previously reported disparities in surgical resection and surgery refusal rates, racial/ethnic disparities also exist earlier in the course of treatment, with non-white patients being less likely to be offered surgery for SBNEN but not for PanNEN; this is potentially due to discrepancies in rates of referral to academic centers for pancreas and small bowel malignancies.

Area deprivation and rurality impact overall survival and adjuvant therapy administration in patients with pancreatic ductal adenocarcinoma (PDAC).

BACKGROUND: The impact of neighborhood deprivation on outcomes in patients with pancreatic ductal adenocarcinoma (PDAC) is not well-described and represents an area to improve disparities. METHODS: We retrospectively queried our prospectively maintained database of patients with PDAC (2014-2022). Patients were grouped by Area Deprivation Index (ADI) and rural-urban commuting area (RUCA) codes. Cox proportional hazards models and logistic regressions were used to investigate effect on overall survival (OS) and adjuvant therapy administration. RESULTS: 536 patients were included. High ADI patients (more disadvantaged, n = 184) were more likely to identify as non-Hispanic Black (17.9% vs. 4.8%, p < 0.01) and were more likely to be from rural areas (49.5% vs. 18.5%, p < 0.01). High ADI was independently associated with decreased OS (HR (95% CI): 1.31 (1.01-1.69), p = 0.04). Urban high ADI patients were 3.5 times more likely to receive adjuvant therapy than rural high ADI patients (OR [95% CI]: 3.48 [1.26-9.61], p = 0.02). CONCLUSION: Patients from the most disadvantaged neighborhoods have decreased OS. Access to adjuvant therapy likely contributes to this disparity in rural areas. Investigation into sources of this OS disparity and identification of barriers to adjuvant therapy will be crucial to improve outcomes in underserved patients with PDAC.

Impact of Prehabilitation on Postoperative Mortality and the Need for Non-Home Discharge in High-Risk Surgical Patients.

BACKGROUND: The preoperative period is an important target for interventions (eg Surgical Prehabilitation and Readiness [SPAR]) that can improve postoperative outcomes for older patients with comorbidities. STUDY DESIGN: To determine whether a preoperative multidisciplinary prehabilitation program (SPAR) reduces postoperative 30-day mortality and the need for non-home discharge in high-risk surgical patients, surgical patients enrolled in a prehabilitation program targeting physical activity, pulmonary function, nutrition, and mindfulness were compared with historical control patients from 1 institution's American College of Surgeons (ACS) NSQIP database. SPAR patients were propensity score-matched 1:3 to pre-SPAR NSQIP patients, and their outcomes were compared. The ACS NSQIP Surgical Risk Calculator was used to compare observed-to-expected ratios for postoperative outcomes. RESULTS: A total of 246 patients were enrolled in SPAR. A 6-month compliance audit revealed that overall patient adherence to the SPAR program was 89%. At the time of analysis, 118 SPAR patients underwent surgery with 30 days of follow-up. Compared with pre-SPAR NSQIP patients (n = 4,028), SPAR patients were significantly older with worse functional status and more comorbidities. Compared with propensity score-matched pre-SPAR NSQIP patients, SPAR patients had significantly decreased 30-day mortality (0% vs 4.1%, p = 0.036) and decreased need for discharge to postacute care facilities (6.5% vs 15.9%, p = 0.014). Similarly, SPAR patients exhibited decreased observed 30-day mortality (observed-to-expected ratio 0.41) and need for discharge to a facility (observed-to-expected ratio 0.56) compared with their expected outcomes using the ACS NSQIP Surgical Risk Calculator. CONCLUSIONS: The SPAR program is safe and feasible and may reduce postoperative mortality and the need for discharge to postacute care facilities in high-risk surgical patients.

Low vs Standard-Dose Indocyanine Green in the Identification of Biliary Anatomy Using Near-Infrared Fluorescence Imaging: A Multicenter Randomized Controlled Trial.

BACKGROUND: Near-infrared fluorescence imaging using intravenous indocyanine green (ICG) facilitates intraoperative identification of biliary anatomy. We hypothesize that a much lower dose of ICG than the standard decreases hepatic and background fluorescence and improves bile duct visualization. STUDY DESIGN: In this multicenter randomized controlled trial, 55 adult patients undergoing laparoscopic cholecystectomy were randomized to low-dose (0.05 mg) or standard-dose (2.5 mg) ICG preoperatively on the day of surgery. A quantitative assessment was performed on recorded videos from the operation using ImageJ software to quantify the fluorescence intensity of the bile duct, liver, and surrounding/background fat. Operating surgeons blinded to ICG dose provided a qualitative assessment of various aspects of the visualization of the extrahepatic biliary tree comparing near-infrared fluorescence to standard visible light imaging using a scale of 1 to 5 (1, unsatisfactory; 5, excellent). Quantitative and qualitative scores were compared between the groups to determine any significant differences between the doses. RESULTS: The bile duct-to-liver and bile duct-to-background fat fluorescence intensity ratios were significantly higher for the low-dose group compared with the standard-dose group (3.6 vs 0.68, p < 0.0001; and 7.5 vs 3.3, p < 0.0001, respectively). Low-dose ICG had a slightly higher (ie better) mean score on the qualitative assessment compared to the standard dose, although the differences were not statistically significant. CONCLUSIONS: Low-dose ICG leads to quantitative improvement of biliary visualization using near-infrared fluorescence imaging by minimizing liver fluorescence; this further facilitates routine use during hepatobiliary operations.

4,300 steps per day prior to surgery are associated with improved outcomes after pancreatectomy.

BACKGROUND: Decreased preoperative physical fitness and low physical activity have been associated with preoperative functional reserve and surgical complications. We sought to evaluate daily step count as a measure of physical activity and its relationship with post-pancreatectomy outcomes. METHODS: Patients undergoing pancreatectomy were given a remote telemonitoring device to measure their preoperative levels of physical activity. Patient activity, demographics, and perioperative outcomes were collected and compared in univariate and multivariate logistic regression analysis. RESULTS: 73 patients were included. 45 (61.6%) patients developed complications, with 17 (23.3%) of those patients developing severe complications. These patients walked 3437.8 (SD 1976.7) average daily steps, compared to 5918.8 (SD 2851.1) in patients without severe complications (p < 0.001). In logistic regression analysis, patients who walked less than 4274.5 steps had significantly higher odds of severe complications (OR = 7.5 (CI 2.1, 26.8), p = 0.002). CONCLUSION: Average daily steps below 4274.5 before surgery are associated with severe complications after pancreatectomy. Preoperative physical activity levels may represent a modifiable target for prehabilitation protocols.

Acinar cell carcinoma with PRKAR1A and PTEN alterations and paraneoplastic panniculitis.

Pancreatic acinar cell carcinoma is a rare type of pancreatic malignancy, which can be confused with pancreatic neuroendocrine neoplasm. Here, we describe a woman in her 80s who presented with abdominal pain and bilateral lower extremity panniculitis. She underwent surgery for a presumed diagnosis of neuroendocrine tumour with PTEN and PRKAR1A alterations; 19 months, later, a recurrence of her pancreatic malignancy was discovered. The patient underwent repeat resection and this time immunohistochemical staining confirmed the diagnosis of acinar cell carcinoma. Staining for acinar cell carcinoma should be prompted based on clinical suspicion in context of PTEN or PRKAR1A mutation when appropriate.

An Analysis of Diversity Statements and Support of Special Interest Societies by General Surgery Residency Programs.

OBJECTIVE: The purpose of this study was to characterize the nondiscrimination and diversity, equity, and inclusion (DEI) statements found on the websites of general surgery residency programs, as well as to measure programmatic commitment to diversity through their involvement with special interest surgical societies (SISS). DESIGN: The authors evaluated the relationship between DEI statements and SISS participation, and performed a natural language processing analysis of general surgery residency DEI statements. SETTING: The residency program websites from 319 non-military general surgery residency programs within the United States were analyzed. PARTICIPANTS: This study evaluated the DEI statement and SISS participation in general surgery residency programs. RESULTS: Of the 319 general surgery residency websites reviewed, 127 (39.8%) featured an identifiable statement of nondiscrimination or commitment to diversity. Compared to programs without diversity statements, programs with statements were more likely to be involved with special interest surgical societies (53.5% vs 30.7%, p < 0.001). Natural language processing analysis revealed that the diversity statements of programs with SISS involvement had higher word counts (p = 0.001), higher clout scores (measure of confidence conveyed, p = 0.001), and higher positive tone scores (p = 0.006) compared with the statements of those without special interest society involvement. CONCLUSIONS: In the era of virtual interviewing, applicants are forced to rely heavily on surgery residency websites as their main source of information. Less than 40% of programs participating in the Match in 2022 feature diversity statements on their websites. Programs with some degree of involvement with special interest societies were more likely to have statements that score higher in confidence and positivity in natural language processing analysis, which may potentially reflect a more earnest commitment to diversity, equity, and inclusion. Residency programs should continue to improve the visibility of their DEI efforts to recruit a diverse resident class.

Preoperative transversus abdominis plane block decreases intraoperative opiate use during pancreatoduodenectomy.

BACKGROUND: Multimodal analgesia and regional anesthetic blocks, such as transversus abdominis plane (TAP) block, decrease postoperative opiate consumption but their effect on intraoperative opiates is unknown. METHODS: This was a retrospective review of patients undergoing pancreatoduodenectomy between June 2018 and February 2021, in which perioperative data, operative times, and medication administration data were collected. Intraoperative opiate use was calculated in total morphine equivalent doses (MED) for each patient and adjusted for operative time. Univariate analysis and multivariate linear regression were performed to determine factors affecting intraoperative opiate requirements. RESULTS: Of the 169 patients in the study, 51 (30.2%) received pre-surgical TAP blocks and 118 (69.8%) did not. There were no statistically significant differences in intraoperative opiate use with preoperative acetaminophen (p = 0.527), celecoxib (p = 0.553), gabapentin (p = 0.308), intraoperative ketorolac (p = 0.698) or epidural placement (p = 0.086). Minimally invasive surgery had lower intraoperative opiate use compared to open (p = 0.011), as well as pre-surgical TAP block compared to no pre-surgical block (5.24 vs 7.27 MED/hour, p < 0.001). On multivariate linear regression, pre-surgical TAP block (p = 0.001) was independently associated with decreased intraoperative opiate use. CONCLUSION: Preoperative TAP blocks were associated with decreased intraoperative opiate use during pancreatoduodenectomy and should be considered for routine use.

Improved outcomes with minimally invasive pancreaticoduodenectomy in patients with dilated pancreatic ducts: a prospective study.

BACKGROUND: Little is known about what factors predict better outcomes for patients who undergo minimally invasive pancreaticoduodenectomy (MIPD) versus open pancreaticoduodenectomy (OPD). We hypothesized that patients with dilated pancreatic ducts have improved postoperative outcomes with MIPD compared to OPD. METHODS: All patients undergoing pancreaticoduodenectomy were prospectively followed over a time period of 47 months, and perioperative and pathologic covariates and outcomes were compared. Ideal outcome after PD was defined as follows: (1) no complications, (2) postoperative length of stay < 7 days, and (3) negative (R0) margins on pathology. Patients with dilated pancreatic ducts (≥ 3 mm) who underwent MIPD were 1:3 propensity score-matched to patients with dilated ducts who underwent OPD and outcomes compared. Likewise, patients with non-dilated pancreatic ducts (< 3 mm) who underwent MIPD were 1:3 propensity score-matched to patients with non-dilated ducts who underwent OPD and outcomes were compared. RESULTS: 371 patients underwent PD-74 (19.9%) MIPD and 297 (80.1%) underwent OPD. Overall, patients who underwent MIPD had significantly less intraoperative blood loss. After 1:3 propensity score matching, patients with dilated pancreatic ducts who underwent MIPD (n = 45) had significantly lower overall complication and 90-day readmission rates compared to matched OPD patients (n = 135) with dilated ducts. Patients with dilated duct who underwent MIPD were more likely to have an ideal outcome than patients with OPD (29 vs 15%, p = 0.035). There were no significant differences in postoperative outcomes among propensity score-matched patients with non-dilated pancreatic ducts who underwent MIPD (n = 29) compared to matched patients undergoing OPD (n = 87) with non-dilated ducts. CONCLUSIONS: MIPD is safe with comparable perioperative outcomes to OPD. Patients with pancreatic ducts ≥ 3 mm appear to derive the most benefit from MIPD in terms of fewer complications, lower readmission rates, and higher likelihood of ideal outcome.

Standardized oral examinations allow for assessment of medical student clinical knowledge and decrease racial grading differences in a surgery clerkship.

BACKGROUND: Oral examinations are not consistently included in third-year medical student clerkships. When included, they are often unstructured, leaving room for variations in difficulty or scoring. Previous research has demonstrated differences in clinical grade achievement, with underrepresented in medicine students receiving significantly lower grades than White students. METHODS: We designed a structured oral examination for third-year medical students on the surgery clerkship. Students completed 2 oral examination scenarios and were evaluated on their ability to complete a history and diagnostic workup, interpret laboratory and imaging results, and devise a treatment plan. Scores from our examination were compared to previous, unstructured oral examination scores and to student demographics. Students and faculty were surveyed regarding their experience. RESULTS: Third-year medical students demonstrated strong knowledge of multiple surgical diseases. The greatest number of errors occurred in treatment planning (P < .001). Third-year medical students receiving honors clerkship grades achieved higher percentages of correct items on their oral examination. (94.8% vs 90.4%) (P = .02). Evaluation of prior unstructured oral examinations found underrepresented in medicine students received lower scores than White students (P = .04). After implementation of our structured examination, no difference was seen between the scores of underrepresented in medicine and White students (P = .99). CONCLUSION: We implemented a standardized oral examination for third-year medical students on the surgery clerkship with student and faculty satisfaction and demonstrated the ability to determine domains of knowledge weakness. The application of our structured oral examination helped to address nonspecific grading practices and eliminate oral examination grade differences between underrepresented in medicine and White students.

Inability to manage non-severe complications on an outpatient basis increases non-white patient readmission rates after pancreaticoduodenectomy: A large metropolitan tertiary care center experience.

BACKGROUND: Pancreaticoduodenectomy (PD) has a high rate of readmission, and racial disparities in care could be an important contributor. METHODS: Patients undergoing PD were prospectively followed, and their complications graded using the Modified Accordion Grading System (MAGS). Patient factors and perioperative outcomes for patients with and without postoperative readmission were compared in univariate and multivariate analysis by severity. RESULTS: 837 patients underwent PD, the overall 90-day readmission rate was 27.5%. Non-white race was independently associated with readmission (OR 1.83, p = 0.007). 51.3% of readmissions were for non-severe complications (MAGS <3). Non-white race was independently associated with MAGS non-severe readmission (OR 2.13, p = 0.006), but not MAGS severe readmission. CONCLUSIONS: Non-white patients are more likely to be readmitted, particularly for non-severe complications. Follow up protocols should be tailored to address race disparities in the rates of readmission as readmission for less severe complications could potentially be avoidable.

Micro-Dosing of Indocyanine Green for Intraoperative Fluorescence Cholangiography.

BACKGROUND: Surgery involving the biliary tree is common but has the potential for serious complications. Adjuncts such as intraoperative cholangiogram and, more recently, indocyanine green (ICG) fluorescence cholangiography, have been used to more accurately define the relevant anatomy and decrease the risk of common bile duct injury. The optimal ICG dose is unknown, but the most commonly cited dose in the literature is 2.5 mg. We describe our experience using micro-dosing of ICG as proof-of-concept for its successful use in the identification of biliary structures. METHODS: A video library from a variety of hepatobiliary surgeries which included micro-dosing of ICG was compiled between 2018 and 2020. These videos were retrospectively reviewed and graded for the degree of visualization of biliary structures (complete, partial, none) and the degree of background liver fluorescence (significant, moderate, minimal). RESULTS: Overall, 40 videos were reviewed; 70% were minimally invasive cholecystectomies. Micro-dosing was used in all patients; complete visualization was achieved in 52.5% of the patients, partial visualization in 40%, and no visualization in 7.6%. Eighty percent of patients had minimal to moderate background fluorescence. Despite ICG micro-dosing, 20% of the patients still had significant liver dye uptake. CONCLUSION: ICG cholangiography is an alternative to more invasive means of intraoperative imaging during biliary surgery, but the optimal dose of ICG is unknown. We have used a 0.05 mg micro-dose of ICG to successfully visualize biliary structures and reduce background liver fluorescence. This preliminary report can be used to develop further studies into whether micro-dosing of ICG is associated with improved clinical outcomes.

Ergonomic analysis of laparoscopic and robotic surgical task performance at various experience levels.

INTRODUCTION: Traditional laparoscopic surgery (TLS) has increasingly been associated with physical muscle strain for the operating surgeon. Robot-assisted laparoscopic surgery (RALS) may offer improved ergonomics. Ergonomics for the surgeon on these two platforms can be compared using surface electromyography (sEMG) to measure muscle activation, and the National Aeronautics and Space Administration Task Load Index (NTLX) survey to assess workload subjectively. METHODS: Subjects were recruited and divided into groups according to level of expertise in traditional laparoscopic (TLS) and robot-assisted laparoscopic surgery (RALS): novice, traditional laparoscopic surgeons (TL surgeons), robot-assisted laparoscopic surgeons (RAL surgeons). Each subject performed three fundamentals of laparoscopic surgery (FLS) tasks in randomized order while sEMG data were obtained from bilateral biceps, triceps, deltoid, and trapezius muscles. After completing all tasks, subjects completed the NTLX survey. sEMG data normalized to the maximum voluntary contraction of each muscle (MVC%), and NTLX data were compared with unpaired t tests and considered significant with a p ≤ 0.05. RESULTS: Muscle activation was higher during TLS compared to RALS in most muscle groups for novices except for the trapezius muscles. Muscle activation scores were also higher for TLS among the groups with more experience, but the differences were less significant. NTLX scores were higher for the TLS platform compared to the RALS platform for novices. DISCUSSION: TLS is associated with higher muscle activation in all muscle groups except for trapezius muscles, suggesting greater strain on the surgeon. Increased trapezius muscle activation on RALS has previously been documented and is likely due to the position of the eye piece. The differences seen in muscle activation diminish with increasing levels of expertise. Experience likely mitigates the ergonomic disadvantage of TLS. NTLX survey data suggest there are subjective benefits to RALS, namely in the perception of temporal demand. Further research to correlate NTLX data and sEMG measurements, and to investigate whether these metrics affect patient outcomes is warranted.
