Randomised, blinded, cross-over evaluation of the palatability of and preference for different potassium binders in participants with chronic hyperkalaemia in the USA, Canada and Europe: the APPETIZE study.

OBJECTIVES: Traditional potassium (K+) binders for treating hyperkalaemia are unpalatable and poorly tolerated. Newer K+ binders are reportedly better tolerated; however, no published data describe their palatability, a determinant of long-term adherence. This study evaluated the palatability of and preference for three K+ binders: sodium and calcium polystyrene sulfonate (S/CPS), sodium zirconium cyclosilicate (SZC) and calcium patiromer sorbitex (patiromer). DESIGN: Phase 4, randomised, participant-blinded, cross-over study. Participants were randomised to one of six taste sequences and, using a 'sip and spit' approach, tasted each K+ binder before completing a survey. SETTING: 17 centres across the USA, Canada and European Union. PARTICIPANTS: 144 participants with chronic kidney disease, hyperkalaemia and no recent use of K+ binders. MAIN OUTCOME MEASURES: For the primary (USA) and key secondary (Canada and European Union) endpoints, participants rated palatability attributes (taste, texture, smell and mouthfeel) and willingness to take each K+ binder on a scale of 0-10 (rational evaluation). Feelings about each attribute, and the idea of taking the product once daily, were evaluated using a non-verbal, visual measure of emotional response. Finally, participants ranked the K+ binders according to palatability. RESULTS: In each region, SZC and patiromer outperformed S/CPS on overall palatability (a composite of taste, texture, smell and mouthfeel), based on rational evaluation and emotional response. Taking the product once daily was more appealing for SZC and patiromer, creating greater receptivity than the idea of taking S/CPS. The emotional response to mouthfeel had the strongest influence on feelings about taking each product. In each region, a numerically greater proportion of participants ranked SZC as the most preferred K+ binder versus patiromer or S/CPS. CONCLUSIONS: Preference for more palatable K+ binders such as SZC and patiromer may provide an opportunity to improve adherence to long-term treatment of hyperkalaemia.

Incorporation and Utilization of an Additional Needs Screener by Surgical Trainees for Comprehensive Care of Underserved and Underinsured Surgical Patients.

OBJECTIVE: Comprehensive, socially-minded healthcare has historically been delivered in the primary care setting. For underserved patient populations, however, a surgical care episode may serve as the health care access point. To maximize patient wellbeing during the perioperative period, our surgical center developed the Additional Needs Screener (ANS). Operationalized into practice by GME and UME trainees, this tool screens surgical patients across 3 domains (social, emotional, and immigration needs) and connects patients to partner organizations if appropriate. This study describes the pilot utilization of the ANS among underserved and underinsured surgical patients. DESIGN: Clinical quality improvement and retrospective cohort study of patients completing the ANS from implementation in September 2021 to September 2022. SETTING: The Hospital of the University of Pennsylvania, PA-a tertiary care center. PARTICIPANTS: One hundred and 10 underinsured and/or underserved patients completed at least 1 ANS domain. RESULTS: Patients were majority female (55F, 53M, 2 other) and Hispanic/Latinx (72%) with a median age of 38 (IQR = 34-48). Most patients spoke a primary language other than English (77%), and nearly all were either uninsured (82%) or received emergency medical assistance or Medicaid (14%) at referral. Patients demonstrated significant needs; 39% endorsed difficulty affording housing, 32% endorsed difficulty paying for food, 29% endorsed experiencing current life-interfering distress, and 75% had undocumented immigration status. Ultimately, 57% of screened patients accepted referrals to our needs response teams. CONCLUSIONS: Underserved and underinsured patients presenting for surgical care face significant challenges relating to social, emotional, and immigration needs. Through adoption of the ANS, trainees gained competency identifying and addressing these barriers in the perioperative period. Future works will focus on categorizing referral outcomes, developing interventions to increase patient trust, and improving screener dissemination.

Evaluation of the educational quality of publicly available online videos on laparoscopic jejunostomy by utilizing the LAP-VEGaS guidelines.

BACKGROUND: Despite its common nature, there is no data on the educational quality of publicly available laparoscopic jejunostomy training videos. The LAParoscopic surgery Video Educational GuidelineS (LAP-VEGaS) video assessment tool, released in 2020, has been developed to ensure that teaching videos are of appropriate quality. This study applies the LAP-VEGaS tool to currently available laparoscopic jejunostomy videos. METHODS: A retrospective review of YouTube® videos was conducted for "laparoscopic jejunostomy." Included videos were rated by three independent investigators using LAP-VEGaS video assessment tool (0-18). Wilcoxon rank-sum test was used to evaluate differences in LAP-VEGaS scores between video categories and date of publication relative to 2020. Spearman's correlation test was performed to measure association between scores and length, number of views and likes. RESULTS: 27 unique videos met selection criteria. Academic and physician video walkthroughs did not demonstrate a significant difference in median scores (9.33 IQR 6.33, 14.33 vs. 7.67 IQR 4, 12.67, p = 0.3951). Videos published after 2020 demonstrated higher median scores than those published before 2020 (13 IQR 7.5, 14.67 vs. 5 IQR 3, 9.67, p = 0.0081). A majority of videos failed to provide patient position (52%), intraoperative findings (56%), operative time (63%), graphic aids (74%), and audio/written commentary (52%). A positive association was demonstrated between scores and number of likes (rs = 0.59, p = 0.0011) and video length (rs = 0.39, p = 0.0421), but not number of views (rs = 0.17, p = 0.3991). CONCLUSION: The majority of available YouTube® videos on laparoscopic jejunostomy fail to meet the basic educational needs of surgical trainees, and there is no difference between those produced by academic centers or independent physicians. However, there has been improvement in video quality following the release of the scoring tool. Standardization of laparoscopic jejunostomy training videos with the LAP-VEGaS score can ensure that videos are of appropriate educational value with logical structure.

Non-English Primary Language: A Growing Population's Access to Cholecystectomy.

OBJECTIVE: To examine access to cholecystectomy and postoperative outcomes among non-English primary-speaking patients. BACKGROUND: The population of U.S. residents with limited English proficiency is growing. Language affects health literacy and is a well-recognized barrier to health care in the United States of America. Historically marginalized communities are at greater risk of requiring emergent gallbladder operations. However, little is known about how primary language affects surgical access and outcomes of common surgical procedures, such as cholecystectomy. METHODS: We conducted a retrospective cohort study of adult patients after receipt of cholecystectomy in Michigan, Maryland, and New Jersey utilizing the Healthcare Cost and Utilization Project State Inpatient Database and State Ambulatory Surgery and Services Database (2016-2018). Patients were classified by primary spoken language: English or non-English. The primary outcome was admission type. Secondary outcomes included operative setting, operative approach, in-hospital mortality, postoperative complications, and length of stay. Multivariable logistics and Poisson regression were used to examine outcomes. RESULTS: Among 122,013 patients who underwent cholecystectomy, 91.6% were primarily English speaking and 8.4% were non-English primary language speaking. Primary non-English speaking patients had a higher likelihood of emergent/urgent admissions (odds ratio: 1.22, 95% CI: 1.04-1.44, P = 0.015) and a lower likelihood of having an outpatient operation (odds ratio: 0.80, 95% CI: 0.70-0.91, P = 0.0008). There was no difference in the use of a minimally invasive approach or postoperative outcomes based on the primary language spoken. CONCLUSIONS: Non-English primary language speakers were more likely to access cholecystectomy through the emergency department and less likely to receive outpatient cholecystectomy. Barriers to elective surgical presentation for this growing patient population need to be further studied.

Introducing Surgical Equity into Contemporary Medical Education: Results From Operation Equity, a Pilot Curriculum.

OBJECTIVE: To date, education about health equity for early-stage healthcare trainees is largely situated outside of surgical disciplines. This study aims to evaluate the effectiveness of a surgical equity curriculum offered to a voluntary group of medical and graduate students. DESIGN: Mixed-methods cohort study from January to June 2021. Pre- and post-course surveys measured domains of attitudes, self-reported confidence, and knowledge via 5-point Likert scale and multiple-choice questions. Paired t tests were used to analyze quantitative responses. Qualitative responses were studied via iterative thematic analysis. SETTING: At the University of Pennsylvania in Philadelphia, PA which provides tertiary level, institutional care, 10, interdisciplinary 1.5-hour sessions were held over 1 semester, teaching surgical equity topics that spanned the peri-operative continuum. PARTICIPANTS: Twenty-four medical and graduate students from across the University of Pennsylvania enrolled. Twenty completed both surveys. RESULTS: From pre- to post-course, students improved across all domains. Students improved in their self-rated ability to identify strategies to talk about sensitive health topics with patients (pre: 20%, post: 90%) and identify strategies to address healthcare disparities in surgery (pre: 10%, post: 90%). Qualitatively, from pre- to post-course, more students could articulate the role of bias and identify opportunities for surgeons to engage in surgical equity. The course strengthened any pre-existing interest in surgical equity, and for 1 student, created interest in a surgical career where it had not previously existed. Many also expressed greater resolve to provide patient-centric care. CONCLUSIONS: Formal curricula can improve students' ability to advocate for surgical equity. A similar framework may fill a need for medical students interested in health equity and surgical careers at other institutions.

Reoperation Through a Prosthetic-Reinforced Abdominal Wall and Its Association With Postoperative Outcomes and Longitudinal Health Care Utilization.

Importance: Prosthetic reinforcement of critically sized incisional hernias is necessary to decrease hernia recurrence, but long-term prosthetic-mesh footprint may increase complication risk during subsequent abdominal operations. Objective: To investigate the association of prior incisional hernia repair with mesh (IHRWM) with postoperative outcomes and health care utilization after common abdominal operations. Design, Setting, and Participants: This was a population-based, retrospective cohort study of patients undergoing inpatient abdominal surgical procedures during the period of January 2009 to December 2016, with at least 1 year of follow-up within 5 geographically diverse statewide inpatient/ambulatory databases (Florida, Iowa, Nebraska, New York, Utah). History of an abdominal operation was ascertained within the 3-year period preceding the index operation. Patients admitted to the hospital with a history of an abdominal operation (ie, bariatric, cholecystectomy, small- or large-bowel resection, prostatectomy, gynecologic) were identified using the International Classification of Diseases, Ninth Revision and Tenth Revision, Clinical Modification procedure codes. Patients with prior IHRWM were propensity score matched (1:1) to controls both with and without a history of an abdominal surgical procedure based on clinical and operative characteristics. Data analysis was conducted from March 1 to November 27, 2021. Main Outcomes and Measures: The primary outcome was a composite of adverse postoperative outcomes (surgical and nonsurgical). Secondary outcomes included health care utilization determined by length of hospital stay, hospital charges, and 1-year readmissions. Logistic and Cox regression determined the association of prior IHRWM with the outcomes of interest. Additional subanalyses matched and compared patients with prior IHR without mesh (IHRWOM) to those with a history of an abdominal operation. Results: Of the 914 105 patients undergoing common abdominal surgical procedures (81 123 bariatric [8.9%], 284 450 small- or large-bowel resection [31.1%], 223 768 cholecystectomy [24.5%], 33 183 prostatectomy [3.6%], and 291 581 gynecologic [31.9%]), all 3517 patients (age group: 46-55 years, 1547 [44.0%]; 2396 majority sex [68.1%]) with prior IHRWM were matched to patients without a history of abdominal surgical procedures. After matching, prior IHRWM was associated with increased overall complications (odds ratio [OR], 1.43; 95% CI, 1.27-1.60), surgical complications (OR, 1.51; 95% CI, 1.34-1.70), length of hospital stay (mean increase of 1.03 days; 95% CI, 0.56-1.49 days; P < .001), index admission charges (predicted mean difference of $11 896.10; 95% CI, $6096.80-$17 695.40; P < .001), and 1-year unplanned readmissions (hazard ratio, 1.14; 95% CI, 1.05-1.25; P = .002). This trend persisted even when comparing matched patients with prior IHRWM to patients with a history of abdominal surgical procedures, and the treatment outcome disappeared when comparing patients with prior IHRWOM to those without a previous abdominal operation. Conclusions and Relevance: Reoperation through a previously prosthetic-reinforced abdominal wall was associated with increased surgical complications and health care utilization. This risk appeared to be independent of a history of abdominal surgical procedures and was magnified by the presence of a prosthetic-mesh footprint in the abdominal wall.

The Center for Surgical Health: A Compassion-Driven Urban Surgical Mission.

We are the Center for Surgical Health (CSH), an academic community partnership that supports, educates, and advocates for vulnerable Philadelphians with surgical diseases, founded in 2016 by Dr. Jon B. Morris, a leader in surgical education and a general surgeon at the University of Pennsylvania, and Dr. Alan Herbst, a current third-year Penn general surgery resident. At the time, Dr. Morris, raised in a Reform Jewish household, had been participating in an RCIA Program to convert to Catholicism. The mission of providing surgery to uninsured patients, primarily undocumented individuals, by helping them obtain insurance and see Penn providers was seen by Dr. Morris as a form of Catholic charity, which he has continued to remain dedicated to as his faith in Jesus Christ has deepened. Dr. Herbst, now Associate Director of Clinics for the CSH, recalls working with Dr. Morris as a sub-intern during his conversion, beginning with passion and a neon poster board inviting people to "See the Surgeon." Since that time, the CSH has grown from an organization with 10 volunteers, called "personal patient navigators," who provide insurance support and advocacy at every step of the perioperative continuum, to one with over 50, who have now seen 156 patients and assisted in providing 49 needed procedures. Much of this growth has been brought about through the dedication and vision of Dr. Matthew Goldshore, the Deputy Director of the CSH and a fifth-year Penn general surgery resident, as well as Dr. Carrie Z. Morales, Associate Deputy Director of the CSH and a recent Perelman School of Medicine graduate. Through their leadership, and the talent and commitment of other members of the CSH board, overseen by Director Dr. Morris, the CSH now has policy and research divisions, a surgical equity curriculum, and continues to develop new ways of providing better care.

(Re)thinking the Residential in Residency: Modern Surgical Practice Continues to Move Away From the Inpatient Setting.

PURPOSE: Despite the overall shift in care delivery to an ambulatory setting, the majority of general surgical education still relies on the experience of caring for inpatients. We aimed to investigate how the inpatient practice patterns of newly minted general surgeons (GS) have changed since 2008, in order to better inform education policies regarding both training approach and setting for modern surgical trainees. METHODS: State discharge data from NY and FL (2008-2017) were linked to data on GS from the American Medical Association Masterfile, and to hospital data from the American Hospital Association annual survey. Mean annual inpatient case volume (CV) and case type breadth (CB) were compared between surgeons who were new-to-practice (0-3 years of experience) in 2008 and in 2013. Each new surgeon cohort was followed for 5 years. Case type was classified by organ system. RESULTS: The 2008 cohort included 328 GS with a mean age of 37.1, 79.6% male and 94.2% board-certified. The 2013 cohort included 359 GS with a mean age of 36.2, 73.0% male and 93.9% board-certified. CV was higher among the 2008 cohort than the 2013 cohort for each year of practice in the study period. CB included at least 4 organ system types for all new GS with greater breadth among the 2008 cohort for each year in the study period. CONCLUSIONS: Declining rates of inpatient surgery affect general surgeons who were new-to-practice in 2013 significantly more than those entering practice only 5 years ahead of them. New surgeons continue to start their practices broadly, suggesting a need to continue broad training while expanding formal educational policies to include the full spectrum of ambulatory surgery.

Surgical Boot Camps Increases Confidence for Residents Transitioning to Senior Responsibilities.

OBJECTIVE: Surgical boot camps enhance the confidence of medical students and surgical interns. The impact of boot camps on the confidence of post-graduate year (PGY) 2 residents is unknown. We hypothesized that a postinternship boot camp would improve the confidence of PGY-2 residents in managing their newfound responsibilities. We also hypothesized that the effect of a tailored high-impact boot camp would persist over time. DESIGN: A 2-hour boot camp at our simulation center was implemented for PGY-2 residents in 2016 and 2017. Confidence in handling boot camp scenarios was measured on a 1 to 5 Likert scale before and after the boot camp. Three-month follow-up was assessed in the 2017 cohort. PARTICIPANTS: Thirty-one PGY-2 residents (n = 16 in 2016, n = 15 in 2017) completed the boot camp. RESULTS: Residents reported increased confidence in placing central lines (p < 0.001), placing chest tubes (p = 0.01), managing emergency airways (p < 0.001), running a code (p = 0.03), and fulfilling the role of in-house senior resident (p < 0.001). Three-month follow-up in 2017 (n = 10) demonstrated no difference in confidence compared to postboot camp results. CONCLUSIONS: Boot camps can durably improve confidence in skills expected of PGY-2 residents assuming in-house senior resident responsibilities.

Looking Beyond the Numbers: Increasing Diversity and Inclusion Through Holistic Review in General Surgery Recruitment.

OBJECTIVE: The purpose of this study is the examine the effect of a holistic review process on the recruitment of women and students underrepresented in medicine (UIM) in a general surgery residency program. DESIGN: A retrospective study comparing the proportion of women and UIM students ranked and matched into categorical positions from 2013 to 2020 before and after the implementation of the holistic application review process. United States Medical Licensing Exam (USMLE) scores and American Board of Surgery In-training Exam (ABSITE) scores were also compared between groups. SETTING: General Surgery residency program at a tertiary, academic center. PARTICIPANTS: Medical students applying for and matriculated to categorical positions. RESULTS: After the implementation of holistic review in 2017, there was a statistically significant increase in the proportion of women (42% vs. 61%, p < 0.01) and UIM students (14% vs. 20%, p = 0.046) ranked in our program compared with the prior "traditional" approach. The proportion of matched female (33% vs. 54%, p = 0.11) and UIM applicants (14% vs. 21%, p = 0.48) also increased after holistic review, although the changes were not statistically significant. The median USMLE Step 1 scores were equivalent for both ranked (250 vs. 250, p = 0.81) and matched (250 vs. 249, p = 0.32) applicants before and after the intervention. The median ABSITE scores for the matched intern classes was lower after initiation of holistic review (519 vs. 483, p = 0.01). However, these scores were consistently above the national medians and subgroup analysis showed no difference between the median aggregate ABSITE scores for UIM and female categorical interns and non-UIM males (475 vs. 520, p = 0.09). CONCLUSIONS: Increasing emphasis is being placed on the diversification of residency training to reflect an expanding, diverse patient population. The incorporation of a holistic review process, providing broader assessment of applicants, can play a pivotal role in increasing the proportion of women and UIM students represented in the general surgery recruitment process.

The University of Pennsylvania Medical School Commencement of 1889: Aequanimitas and the Agnew Clinic.

Academic commencements ceremonies usually do not result in memorable occasions and once ended usually are forgotten. Not so for the University of Pennsylvania's School of Medicine commencement on May 1,1889, which was marked by an address by William Osler, the retirement of the renowned Professor of Surgery, D. Hayes Agnew, and the presentation to the University of Thomas Eakins' remarkable masterpiece, "The Agnew Clinic." Osler had been on the faculty of the University for 5 years and in his keynote address, Aequanimitas, he laid out 2 elements, imperturbability and equanimity, that he stated would "make or mar" the lives of the students he was addressing. His words and message that day have continued to resonate for medical students and many others up to the present day. Osler ended his address on a more somber note, seemingly surprising the assembled, by announcing his imminent departure from the University. He would soon be one of the 4 founders of the Johns Hopkins Hospital along with fellow Penn faculty member, Howard Kelly. Osler was not the only one on the verge of leaving as this commencement also marked the end of the career of D. Hayes Agnew. To honor him on this occasion of his retirement the 3 classes of medical students had commissioned Eakins to paint a portrait of their revered professor, which was presented on this commencement day and accepted by Trustee Dr S. Weir Mitchell on behalf of the University. The day was indeed one to be remembered.

The effects of nostalgia cues in sexual health advertising.

An experimental design was conducted to investigate message effectiveness between reminiscence-bump format (RBF)/nostalgia message formats with traditional message formats in the context of health communication ads about sexual health. Reminiscence bumps, defined as a point in one's life where people can recall their life events, are proposed as a means for improving nostalgic advertising message effectiveness measure in the research. The dependent variables were emotional response, response efficacy (i.e. intent to adopt the behavior), attitude toward the message, and attitude toward the ad. Boomer-aged women completed an online survey. The research found evidence in support of the idea that nostalgic cues in health communication ads improved emotional response to the advertisement, which, in turn, improved their interest to act on health message recommendations.

Career Goals, Salary Expectations, and Salary Negotiation Among Male and Female General Surgery Residents.

Importance: In general surgery, women earn less money and hold fewer leadership positions compared with their male counterparts. Objective: To assess whether differences exist between the perspectives of male and female general surgery residents on future career goals, salary expectations, and salary negotiation that may contribute to disparity later in their careers. Design, Setting, and Participants: This study was based on an anonymous and voluntary survey sent to 19 US general surgery programs. A total of 606 categorical residents at general surgery programs across the United States received the survey. Data were collected from August through September 2017 and analyzed from September through December 2017. Main Outcomes and Measures: Comparison of responses between men and women to detect any differences in career goals, salary expectation, and perspectives toward salary negotiation at a resident level. Results: A total of 427 residents (70.3%) responded, and 407 responses (230 male [58.5%]; mean age, 30.0 years [95% CI, 29.8-30.4 years]) were complete. When asked about salary expectation, female residents had lower expectations compared with men in minimum starting salary ($249 502 [95% CI, $236 815-$262 190] vs $267 700 [95% CI, $258 964-$276 437]; P = .003) and in ideal starting salary ($334 709 [95% CI, $318 431-$350 987] vs $364 663 [95% CI, $351 612-$377 715]; P < .001). Women also had less favorable opinions about salary negotiation. They were less likely to believe they had the tools to negotiate (33 of 177 [18.6%] vs 73 of 230 [31.7%]; P = .03) and were less likely to pursue other job offers as an aid in negotiating a higher salary (124 of 177 [70.1%] vs 190 of 230 [82.6%]; P = .01). Female residents were also less likely to be married (61 of 177 [34.5%] vs 116 of 230 [50.4%]; P = .001), were less likely to have children (25 of 177 [14.1%] vs 57 of 230 [24.8%]; P = .008), and believed they would have more responsibility at home than their significant other (77 of 177 [43.5%] vs 35 of 230 [15.2%]; P < .001). Men and women anticipated working the same number of hours, expected to retire at the same age, and had similar interest in holding leadership positions, having academic careers, and pursuing research. Conclusions and Relevance: This study found no difference in overall career goals between male and female residents; however, female residents' salary expectations were lower, and they viewed salary negotiation less favorably. Given the current gender disparities in salary and leadership within surgery, strategies are needed to help remedy this inequity.

Factors associated with general surgery residents' decisions regarding fellowship and subspecialty stratified by burnout and quality of life.

BACKGROUND: Although most surgery residents pursue fellowships, data regarding those decisions are limited. This study describes associations with interest in fellowship and specific subspecialties. METHODS: Anonymous surveys were distributed to 607 surgery residents at 19 US programs. Subspecialties were stratified by levels of burnout and quality of life using data from recent studies. RESULTS: 407 (67%) residents responded. 372 (91.4%) planned to pursue fellowship. Fellowship interest was lower among residents who attended independent or small programs, were married, or had children. Residents who received AOA honors or were married were less likely to choose high burnout subspecialties (trauma/vascular). Residents with children were less likely to choose low quality of life subspecialties (trauma/transplant/cardiothoracic). CONCLUSIONS: Surgery residents' interest in fellowship and specific subspecialties are associated with program type and size, AOA status, marital status, and having children. Variability in burnout and quality of life between subspecialties may affect residents' decisions.

Developing and exploring indicators of water sustainable development.

The pressures of rapid economic growth, population increase, and global warming are stretching the availabilities of natural freshwater sources which have implications for economic prosperity and human life. Water resources are entwined in a complex socio-economic system, affected by water demands as well as the environmental implications of pollution and waste discharges. Drawing on existing measures of social and economic wellbeing, this research presents the development of indicators that place economic growth within the context of social and environmental development, presenting a measure that assesses how water resources are used in a manner that is efficient and beneficial to society as a whole. From a study of 37 nations, the findings show that in countries with relatively high (by global standards) economic and social development, there is a discrepancy between social development and the productive use of water resources. This opens up potential applications for policy makers and industry leaders to monitor and measure their progress towards water sustainable practices and enable international comparisons of water sustainable development.

Training Disparities of Our Future Workforce: A Survey of Trauma Fellowship Candidates.

BACKGROUND: Training in Acute Care Surgery (ACS) is an integral component of general surgery residency and serves as a critical base experience for the added educational qualifications of fellowship. How this training varies between programs is not well characterized. We sought to describe the variation in clinical exposure between residencies in a sample of residents applying to an ACS fellowship. We hypothesized that applicants have significant variations in clinical exposure as well as unique and specific expectations for educational experiences. MATERIALS AND METHODS: We offered an anonymous 82-question survey focused on residency clinical exposure and self-perceived confidence in key areas of ACS training, as well as fellowship training and career expectations to all applicants interviewed at a single trauma, critical care, and emergency surgery fellowship program. Responses were assessed via absolute numbers and confidence via a 5-point Likert scale; data are reported using descriptive statistics and linear regression models. RESULTS: Forty-two interviewing applicants completed the survey, for a 96% response rate. Applicants reported heterogeneous levels of comfort across most ACS domains. There was good correlation between experience and comfort in most procedural areas. During fellowship training, respondents placed highest priority on operative experience, with 43% rating this as their highest priority, followed by penetrating trauma experience (33%). CONCLUSIONS: We found significant variations in both experience and comfort within key ACS domains among fellowship applicants. Despite training variability, there was good correlation between experience and self-reported comfort. Collaboration between residency and fellowship governing bodies may help address areas of limited exposure before entry into clinical practice.

Detection limits of optical gas imagers as a function of temperature differential and distance.

Optical gas imaging (OGI) is an effective tool for detecting gas leaks from process equipment. Despite the fact that OGI has been used for leak detection for over a decade, its detection limit is an elusive performance metric and has not been systematically characterized and quantified like other detection instruments. A substantial body of research has been performed that has shed some light on the OGI detection limits and the factors that dictate the detection limits. The OGI detection limit expressed as ppm-m and ppm now can be quantified as a function of ΔT (differential temperature between the gas plume and the background), the OGI camera type, and the specific gas in question. Furthermore, the OGI detection limit expressed as grams per hour can be calculated based on the ΔT and the distance from the OGI camera to the leak location under common leak survey conditions. For the same OGI camera, the detection limit can vary by several orders of magnitude due to ΔT and distance. The present work has demonstrated how different OGI detection limits can be. More importantly, this work has, for the first time, formulated equations that can be used to determine OGI detection limits with a given set of leak detection conditions. Being able to quantify OGI detection limit and understand the variables that dictate the detection limit is a significant advancement. It will help OGI to become accepted as a mature field instrument. The variables characterized in this work should have an impact on the development of OGI leak survey protocols, such as Appendix K to Code of Federal Regulations 40 CFR Part 60 in the United States. Established detection limits will also help emission inventory for fugitive emissions when OGI is used as the sole leak detection method. Implications: Optical gas imaging (OGI) has been used for leak detection and control of fugitive volatile organic compound (VOC) emissions and methane emissions due to equipment leaks. However, detection limits of OGI have not been characterized and quantified like other detection instruments. The lack of well-understood detection limits has hindered broader applications of OGI. The work presented in this paper represents important steps that will enable OGI users and policymakers to establish (1) OGI detection limits under various conditions, (2) OGI leak survey criteria for a desired minimum detectable leak size, and (3) maximum potential emissions from the nondetect sources in emission inventory studies.

Using Patient Safety Reporting Systems to Understand the Clinical Learning Environment: A Content Analysis.

OBJECTIVE: To examine patient safety event reporting behavior by trainees caring for surgical patients compared to other clinicians. DESIGN: Qualitative analysis of a patient safety event reporting system comparing reports entered by trainees to those entered by attending physicians and nurses. Categorical data associated with reports were compared, and free-text event descriptions underwent content analysis focusing on themes related to report completeness and report focus. SETTING: The Hospital of the University of Pennsylvania, an academic tertiary care hospital in Philadelphia, Pennsylvania. PARTICIPANTS: All patient safety event reports related to surgical patients from a 6-month period (July-December 2016). RESULTS: One thousand four hundred twenty-three reports were entered by trainees (T), attendings (A), and nurses (N). Trainees had a lower number of reports entered per reporter compared to nurses (T median [IQR]: 1 [1-2], N: 2 [1-3]), and the highest percentage of reports entered anonymously for any group (T: 28.7%, N: 9.9%, A: 4.6%). The overall distribution of event location and event type differed significantly between groups (p < 0.001). Trainee reports were found to have a broader range of focus, more elements associated with completeness of reports, and more frequent use of blame language. CONCLUSIONS: Surgical trainees report a wide variety of issues in the perioperative, floor, and ICU settings. Their reports often include more details than those entered by other clinicians, but feature higher rates of anonymous reporting and use of blame language. Analysis of patient safety event reports by trainees compared with other healthcare professionals can reveal important insights into the clinical learning environment and areas for safety improvement.

Resection of gallbladder remnants after subtotal cholecystectomy: presentation and management.

BACKGROUND: Subtotal cholecystectomy (SC) involves removal of a portion of the gallbladder typically due to hazardous inflammation. While this technique reliably prevents common bile duct (CBD) injury, future procedures can be required if the gallbladder remnant becomes symptomatic. The morbidity associated with resection of gallbladder remnants in patients that previously underwent SC is reviewed. METHODS: Records for patients having undergone redo cholecystectomy for symptomatic gallbladder remnants in a tertiary care system from 2013 to 2017 were retrospectively reviewed. RESULTS: Fourteen patients underwent repeat cholecystectomy. Five surgeons dictated the initial procedure as a subtotal cholecystectomy. All patients returned with symptomatic cholelithiasis between zero months and seven years after the index cholecystectomy. Redo cholecystectomy was attempted laparoscopically in two patients but ultimately required an open approach in all. One patient had a recognized CBD injury requiring a hepaticojejunostomy, and a second patient had a minor wound infection. Symptoms resolved in 13/14 patients. CONCLUSIONS: Redocholecystectomy (RC) for gallbladder remnants has been detailed in case reports, but no sizable North American series have been presented. These results illustrate a drawback to the reconstituting technique of SC. RC effectively resolves symptoms but requires adherence to safe principles of cholecystectomy and is one indication for an open approach.
