Outcomes in Pediatric Burn Patients With Additional Trauma-Related Injuries.

The addition of trauma to burn injuries may result in higher morbidity and mortality. The purpose of this study was to evaluate the outcomes of pediatric patients with a combination of burn and trauma injuries, and included all pediatric Burn only, Trauma only, and combined Burn-Trauma patients admitted between 2011 and 2020. Mean length of stay, ICU length of stay, and ventilator days were highest for the Burn-Trauma group. The odds of mortality were almost 13 times higher for the Burn-Trauma group when compared to the Burn only group (P = .1299). After using inverse probability of treatment weighting, the odds of mortality were almost 10 times higher for the Burn-Trauma group in comparison to the Burn only group (P < .0066). Thus, the addition of trauma to burn injuries was associated with increased odds of mortality, as well as longer ICU and overall hospital length of stay in this patient population.

Survey of the US Surgeon Workforce: Practice Characteristics, Job Satisfaction, and Reasons for Leaving Surgery.

BACKGROUND: An impending surgeon shortage looms in the US due to increasing demand and a stagnant number of surgeons entering practice. We sought to evaluate the state of our surgical workforce by exploring current practice patterns, job satisfaction, and reasons why surgeons consider leaving surgery. STUDY DESIGN: In 2018, a link to a detailed survey was distributed by email to Fellows of the American College of Surgeons (ACS) who actively practice in the US and have completed a general surgery residency or integrated cardiothoracic, vascular, or plastic surgery fellowship. Detailed questions regarding practice attributes, surgical training, professional choices, and career satisfaction were included. Nonresponse weights were adjusted for respondent sex, age, and presence of subspecialty training between respondents and the total surveyed ACS population. All estimates and analyses were weighted to account for potential nonresponse bias. RESULTS: There were 3,807 surgeons who responded (15% response rate). Overall, 81% reported career satisfaction and 80% would choose surgery over again. Twenty-six percent were considering leaving surgery within the next 2 years. Stratified by age groups 40 to 49, 50 to 59, and 60 to 69 years, the survey found that 9%, 17%, and 45% of respondents were considering leaving surgery within the next 2 years, respectively. Thirteen percent of surgeons less than 60 years old were considering leaving surgery, and only 49% of these surgeons reported career satisfaction. Among surgeons less than 60 years old who were considering leaving surgery, the top 3 reasons rated as very important were overall stress (79%), work time demands (77%), and personal time requirements (73%). CONCLUSIONS: Reported surgeon job satisfaction was high, but a surprising number of surgeons reported that they were considering leaving surgery. Work time requirements and lack of personal time are leading factors contributing to surgeons leaving practice.

Risks and Realities of Delayed Splenic Bleeding.

Delayed splenic bleeding (DSB) is a poorly understood complication of blunt splenic injury. Treatment for splenic bleeding may involve splenectomy, but angioembolization is becoming a widely used adjuvant for management. Using the North Carolina Trauma Registry, this study aimed to evaluate the incidence, mortality, and risk factors for DSB in North Carolina. Using ICD-9 and ICD-10 codes, patients were stratified into two cohorts, those who underwent immediate splenectomy and those who were initially managed nonoperatively. DSB was then defined as splenectomy at greater than 24 hours after presentation. Of the 1688 patients included in the study, 269 patients (16%) underwent immediate splenectomy and 1419 (84%) were managed nonoperatively initially, with 32 (2%) having delayed splenectomy. Older age (≥30 years) was associated with increased odds of having delayed splenectomy (odds ratio 4.30; 95% confidence interval 1.08, 17.17; P = 0.04). Four per cent of patients managed nonoperatively and undergoing an angioembolization procedure eventually required splenectomy. Risk factors for DSB remain elusive. Splenic artery embolization may be used as an adjuvant to splenectomy for stable patients, but it is not always a definitive treatment, and patients may still require splenectomy.

Measuring Patterns of Surgeon Confidence Using a Novel Assessment Tool.

Confidence should increase during surgical training and practice. However, few data exist regarding confidence of surgeons across this continuum. Confidence may develop differently in clinical and personal domains, or may erode as specialization or age restricts practice. A reliable scale of confidence is needed to track this competency. A novel survey was distributed to surgeons in private and academic settings. One hundred and thirty-four respondents completed this cross-sectional survey. Surgeons reported anticipated reactions to clinical scenarios within three patient care domains (acute inpatient, nonacute inpatient, and outpatient) and in personal spheres. Confidence scores were plotted against years of experience. Curves of best fit were generated and trends assessed. A subgroup completed a second survey after four years to assess the survey's reliability over time. During residency, there is steep improvement in confidence reported by surgeons in all clinical domains, with further increase for inpatient domains during transition into practice. Confidence in personal spheres also increases quickly during residency and thereafter. The surgeon confidence scale captures the expected acquisition of confidence during early surgical experience, and will have value in following trends in surgeon confidence as training and practice patterns change.

Laser resurfacing and remodeling of hypertrophic burn scars: the results of a large, prospective, before-after cohort study, with long-term follow-up.

OBJECTIVES: Hypertrophic burn scars produce significant morbidity, including itching, pain, stiffness, and contracture, but best management practices remain unclear. We present the largest study to date that examines long-term impact of laser therapies, a potentially transformative technology, on scar remodeling. METHODS: We conducted a prospective, before-after cohort study in burn patients with hypertrophic scars. Pulsed-dye laser was used for pruritus and erythema; fractional CO2 laser was used for stiffness and abnormal texture. Outcomes included (1) Vancouver Scar Scale (VSS), which documents pigmentation, erythema, pliability, and height, and (2) University of North Carolina "4P" Scar Scale (UNC4P), which rates pain, pruritus, paresthesias, and pliability. RESULTS: A total of 147 burn patients (mean age, 26.9 years; total body surface area, 16.1%) received 415 laser sessions (2.8 sessions/patient), 16 months (median) after injury, including pulsed dye laser (n = 327) and CO2 (n = 139). Laser treatments produced rapid, significant, and lasting improvements in hypertrophic scar. Provider-rated VSS dropped from 10.43 [standard deviation (SD) 2.37] to 5.16 (SD 1.92), by the end of treatments, and subsequently decreased to 3.29 (SD 1.24), at a follow-up of 25 months. Patient-reported UNC4P fell from 5.40 (SD 2.54) to 2.05 (SD 1.67), after the first year, and further decreased to 1.74 (SD 1.72), by the end of the study period. CONCLUSIONS: For the first time, ever, in a large prospective study, laser therapies have been shown to dramatically improve both the signs and symptoms of hypertrophic burn scars, as measured by objective and subjective instruments. Laser treatment of burn scars represents a disruptive innovation that can yield results not previously possible and may displace traditional methods of operative intervention.

Acrylic coatings with surprising antifogging and frost-resisting properties.

We report an unusually effective antifogging/frost-resisting coating based on conventional acrylic polymers. The intriguing antifogging property originated from the delicate balance between the hydrophilicity and hydrophobicity of the acrylic copolymers of 2-(dimethylamino)ethyl methacrylate and methyl methacrylate, as well as between the water-swellability of the copolymer and the cross-linked network due to ethylene glycol dimethacrylate.

Bronchoscopy-derived correlates of lung injury following inhalational injuries: a prospective observational study.

BACKGROUND: Acute lung injury (ALI) is a major factor determining morbidity following burns and inhalational injury. In experimental models, factors potentially contributing to ALI risk include inhalation of toxins directly causing cell damage; inflammation; and infection. However, few studies have been done in humans. METHODS: We carried out a prospective observational study of patients admitted to the NC Jaycees Burn Center who were intubated and on mechanical ventilation for burns and suspected inhalational injury. Subjects were enrolled over an 8-month period and followed till discharge or death. Serial bronchial washings from clinically-indicated bronchoscopies were collected and analyzed for markers of cell injury and inflammation. These markers were compared with clinical markers of ALI. RESULTS: Forty-three consecutive patients were studied, with a spectrum of burn and inhalation injury severity. Visible soot at initial bronchoscopy and gram negative bacteria in the lower respiratory tract were associated with ALI in univariate analyses. Subsequent multivariate analysis also controlled for % body surface area burns, infection, and inhalation severity. Elevated IL-10 and reduced IL-12p70 in bronchial washings were statistically significantly associated with ALI. CONCLUSIONS: Independently of several factors including initial inhalational injury severity, infection, and extent of surface burns, high early levels of IL-10 and low levels of IL-12p70 in the central airways are associated with ALI in patients intubated after acute burn/inhalation injury. Lower airway secretions can be collected serially in critically ill burn/inhalation injury patients and may yield important clues to specific pathophysiologic pathways.

The price of acute care surgery.

BACKGROUND: Numerous organizations have identified access to emergency surgical care as a crisis. One barrier is the financial disincentive associated with caring for this patient population. We sought to identify contributing factors by analyzing endemic data during the development of an acute care surgery (ACS) service at an academic health care system. METHODS: Financial data (receipts, payer mix, and dollar/relative value unit [RVU]) and productivity measures (OR procedures and RVUs) were obtained for a surgical division for 6-month periods before and after transition to an ACS model. Using national data, a sensitivity analysis was performed to identify salary targets required for an ACS surgeon to have equitable career reimbursement using standard financial modeling (net present value) with comparable surgical specialists. RESULTS: Post-ACS, operative volume increased 25%, work RVUs increased 21%, but net receipts increased only 11%. Dollar/RVU decreased primarily due to a higher proportion of uncompensated care. As a result, the dollar/RVU for ACS patients was 28% lower in comparison to non-ACS specialties. Increasing ACS salaries proportionate to the observed dollar/RVU discount realigned ACS economic value with other specialties in aggregate. CONCLUSION: A national shortage of ACS surgeons exists due to in part financial misalignment. We demonstrated that despite an increase in clinical activity, transition to an ACS model resulted in a relative reduction in payment. A rational systems-based approach to ACS development that objectively targets the RVU reimbursement disparity would reduce economic disincentives related to careers in ACS and potentially address the emergency surgical care crisis.

Logistics of building a laser practice for the treatment of hypertrophic burn scars.

INTRODUCTION: Although lasers can improve burn scars, such treatment has not been adopted universally, due to operational challenges starting a practice and the perception that such a program is not financially viable. We report the logistics of building a laser practice for the treatment of hypertrophic burn scars. METHODS: We analyzed the clinical, operational, and financial components of our laser practice, focusing on treatment of hypertrophic burn scars, using pulsed dye laser, fractional CO2 laser, and intense pulsed light. Cases were performed in an operating room, with anesthesia, after preauthorization. We examined professional charges and collections, case time, variable and indirect expenses, and breakeven volumes. RESULTS: Our practice grew as follows: 2008, 1 case; 2009, 44 cases; 2010, 169 cases; and 2011, 415 cases. Overall collection rate was 32.1%. Expenses incurred by the provider, per 8-hour session, included laser rental/lease ($2375), personnel salaries ($1900), and physician overhead ($808), for a total cost of $5083. Mean charge was $1642 per case; mean collection was $527 per case. Median case time (procedure plus turnover) was 40 minutes. In this model, breakeven volume is 9.7 cases per day; breakeven time is 49.7 minutes. Provider profit margin for 10 cases per day, or 83% capacity utilization, is $187 per day (income - expenses = $5270 - $5083). CONCLUSIONS: Despite high costs associated with starting and operating a laser practice for the treatment of hypertrophic burn scars, a sustainable enterprise can be achieved when the provider has accrued enough volume to batch cases over an entire day. Critical to achieving breakeven is preauthorization, controlling overhead, and efficient throughput.

Competence and confidence with basic procedural skills: the experience and opinions of fourth-year medical students at a single institution.

PURPOSE: Data indicate that students are unprepared to perform basic medical procedures on graduation. The authors' aim was to characterize graduating students' experience with and opinions about these skills. METHOD: In 2011, an online survey queried 156 fourth-year medical students about their experience with, and actual and desired levels of competence for, nine procedural skills (Foley catheter insertion, nasogastric tube insertion, venipuncture, intravenous catheter insertion, arterial puncture, basic suturing, endotracheal intubation, lumbar puncture, and thoracentesis). Students self-reported competence on a four-point Likert scale (4=independently performs skill; 1=unable to perform skill). Data were analyzed by analysis of variance and Student t test. A five-point Likert scale was used to assess student confidence. RESULTS: One hundred thirty-four (86%) students responded. Two skills were performed more than two times by over 50% of students: Foley catheter insertion and suturing. Mean level of competence ranged from 3.13±0.75 (Foley catheter insertion) to 1.7±0.7 (thoracentesis). A gap in desired versus actual level of competence existed for all procedures (P<.0001). There was a correlation between the number of times a procedure had been performed and self-reported competence for all skills except arterial puncture and suturing. CONCLUSIONS: Participants had performed most skills infrequently and rated themselves as being unable to perform them without assistance. Strategies to improve student experience and competence of procedural skills must evolve to improve the technical competency of graduating students because their current competency varies widely.

Sometimes you can't make it on your own: the impact of a professionalism curriculum on the attitudes, knowledge, and behaviors of an academic plastic surgery practice.

INTRODUCTION: Professionalism is now recognized as a core competency for graduate medical education and maintenance of certification. However, few models exist in plastic surgery that define, teach, and assess professionalism as a competency. The purpose of this project was to evaluate the effectiveness of a professionalism curriculum in an academic plastic surgery practice. METHODS: We created and conducted a 6-wk, 12-h course for health care professionals in plastic surgery (faculty, residents, nurses, medical students). Teaching methods included didactic lectures, journal club, small group discussions, and book review. Topics included: (1) Professionalism in Our Culture, (2) Leadership Styles, (3) Modeling Professional Behavior, (4) Leading Your Team, (5) Managing Oneself, and (6) Leading While You Work. Using Kirkpatrick methodology to assess perception of the course (level 1 data), learning of the material (level 2 data), effect on behavior (level 3 data), and impact on the organization (level 4 data), we compiled participant questionnaires, scores from pre- and post-tests, and such metrics as incidence of sentinel events (defined as infractions requiring involvement by senior administrators), number of patient complaints reported to Patient Relations, and patient satisfaction (Press Ganey surveys), for the 6 mo before and after the course. RESULTS: Thirty health care professionals participated in a 6-wk course, designed to improve professionalism in plastic surgery. Level 1 data: Although only 56.5% of respondents felt that the course was a "good use of my time," 73.9% agreed that the course "will help me become a better professional" and 82.6% "would recommend the course to others." Level 2 data: Post-test scores increased from 48% to 70% (P < 0.05), and the ability to recall all six competencies increased from 22% to 73% (P < 0.01). Level 3 data: The number of sentinel events in our division decreased from 13 to three. After the course, one resident was placed on probation and resigned, and two other employees left the division after being counseled on issues of professionalism. Interestingly, these participants did very well on the post-test but were not considered to be "team players." Level 4 data: Patient complaints decreased from 14 to eight, and patient satisfaction increased from 85.5% to 90.5%. CONCLUSIONS: A focused curriculum in professionalism may improve the knowledge of participants and overall behavior of the group, but may not affect individual attitudes. Nevertheless, efforts toward assessing, teaching, and influencing professionalism in plastic surgery are very valuable and should be pursued by educators to help satisfy Graduate Medical Education/Maintenance of Certification requirements and to improve the performance of the organization.

Projecting surgeon supply using a dynamic model.

OBJECTIVE: To develop a projection model to forecast the head count and full-time equivalent supply of surgeons by age, sex, and specialty in the United States from 2009 to 2028. SUMMARY BACKGROUND DATA: The search for the optimal number and specialty mix of surgeons to care for the United States population has taken on increased urgency under health care reform. Expanded insurance coverage and an aging population will increase demand for surgical and other medical services. Accurate forecasts of surgical service capacity are crucial to inform the federal government, training institutions, professional associations, and others charged with improving access to health care. METHODS: The study uses a dynamic stock and flow model that simulates future changes in numbers and specialty type by factoring in changes in surgeon demographics and policy factors. RESULTS: : Forecasts show that overall surgeon supply will decrease 18% during the period form 2009 to 2028 with declines in all specialties except colorectal, pediatric, neurological surgery, and vascular surgery. Model simulations suggest that none of the proposed changes to increase graduate medical education currently under consideration will be sufficient to offset declines. CONCLUSIONS: The length of time it takes to train surgeons, the anticipated decrease in hours worked by surgeons in younger generations, and the potential decreases in graduate medical education funding suggest that there may be an insufficient surgeon workforce to meet population needs. Existing maldistribution patterns are likely to be exacerbated, leading to delayed or lost access to time-sensitive surgical procedures, particularly in rural areas.

Get on your boots: preparing fourth-year medical students for a career in surgery, using a focused curriculum to teach the competency of professionalism.

INTRODUCTION: Few educational programs exist for medical students that address professionalism in surgery, even though this core competency is required for graduate medical education and maintenance of board certification. Lapses in professional behavior occur commonly in surgical disciplines, with a negative effect on the operative team and patient care. Therefore, education regarding professionalism should begin early in the surgeon's formative process, to improve behavior. The goal of this project was to enhance the attitudes and knowledge of medical students regarding professionalism, to help them understand the role of professionalism in a surgical practice. METHODS: We implemented a 4-h seminar, spread out as 1-h sessions over the course of their month-long rotation, for 4th-year medical students serving as acting interns (AIs) in General Surgery, a surgical subspecialty, Obstetrics/Gynecology, or Anesthesia. Teaching methods included lecture, small group discussion, case studies, and journal club. Topics included Cognitive/Ethical Basis of Professionalism, Behavioral/Social Components of Professionalism, Managing Yourself, and Leading While You Work. We assessed attitudes about professionalism with a pre-course survey and tracked effect on learning and behavior with a post-course questionnaire. We asked AIs to rate the egregiousness of 30 scenarios involving potential lapses in professionalism. RESULTS: A total of 104 AIs (mean age, 26.5 y; male to female ratio, 1.6:1) participated in our course on professionalism in surgery. Up to 17.8% of the AIs had an alternate career before coming to medical school. Distribution of intended careers was: General Surgery, 27.4%; surgical subspecialties, 46.6%; Obstetrics/Gynecology, 13.7%; and Anesthesia, 12.3%. Acting interns ranked professionalism as the third most important of the six core competencies, after clinical skills and medical knowledge, but only slightly ahead of communication. Most AIs believed that professionalism could be taught and learned, and that the largest obstacle was not enough time in the curriculum. The most effective reported teaching methods were mentoring and modeling; lecture and journal club were the effective. Regarding attitudes toward professionalism, the most egregious examples of misconduct were substance abuse, illegal billing, boundary issues, sexual harassment, and lying about patient data, whereas the least egregious examples were receiving textbooks or honoraria from drug companies, advertising, self-prescribing for family members, and exceeding work-hour restrictions. The most important attributes of the professional were integrity and honesty, whereas the least valued were autonomy and altruism. The AIs reported that the course significantly improved their ability to define professionalism, identify attributes of the professional, understand the importance of professionalism, and integrate these concepts into practice (all P < 0.01). CONCLUSIONS: Although medical students interested in surgery may already have well-formed attitudes and sophisticated knowledge about professionalism, this core competency can still be taught to and learned by trainees pursuing a surgical career.

Who teaches basic procedural skills: student experience versus faculty opinion.

INTRODUCTION: Learning procedural skills as a medical student has evolved, as task trainers and simulators are now ubiquitous. It is yet unclear whether they have supplanted bedside teaching or are adjuncts to it, and whether faculty or residents are responsible for student skills education in this era. In this study we sought to characterize the experience and opinions of both medical students and faculty on procedural skills training. METHODS: Surveys were sent to clinical medical students and faculty at UNC Chapel Hill. Opinions on the ideal learning environment for basic procedural skills, as well as who serves as primary teacher, were gathered using a 4-point Likert scale. Responses were compared via Fisher exact test. RESULTS: A total of 237 students and 279 faculty responded. Third-year students were more likely to report simulation as the primary method of education (64%), compared to either fourth-year students (35%; P < 0.0001) or faculty (43%; P = 0.0018). Third- and fourth-year students were also more likely to report interns as a primary teacher (15% and 10%, respectively) as opposed to faculty (2%), and less likely to suggest faculty were the primary teacher (30% and 21%, respectively, versus 35%), P < 0.0001. Residents were the primary teachers for all three groups (55%, 70%, and 63% respectively). CONCLUSIONS: Our data suggest that both medical students and faculty recognize the utility of simulation in procedural skills training, but vary in the degree to which they think simulation is or should be the primary instructional tool. Both groups suggest residents are the primary teacher of these skills.

Effectiveness of a radiofrequency detection system as an adjunct to manual counting protocols for tracking surgical sponges: a prospective trial of 2,285 patients.

BACKGROUND: Despite rigorous manual counting protocols and the classification of retained surgical items (RSIs) as potential "never events," RSIs continue to occur in approximately 1 per 1,000 to 18,000 operations. This study's goals were to evaluate the incorporation of a radiofrequency detection system (RFDS) into existing laparotomy sponge- and Raytec-counting protocols for the detection of RSIs and define associated risk factors. STUDY DESIGN: All patients undergoing surgery at the University of North Carolina Hospitals from September 2009 to August 2010 were enrolled consecutively. The performance of an RFDS-incorporated accounting protocol for detecting RSIs was prospectively evaluated. Several operative metrics were recorded to identify risk factors for miscounts. RESULTS: A total of 2,285 patients were enrolled. One near miss was detected by the RFDS. Thirty-five miscounts occurred, for a rate of 1.53%. The ultimate locations of miscounted items were surgical site (n = 11), within operative suite (n = 10), surgical drapes (n = 2), and emergency protocol deviations (n = 12). Perioperative variables associated with miscounts were higher estimated volume of blood lost, longer operations, higher number of laparotomy sponges used, open surgical approach, "after hours" operations, change of surgical team during operation, weekend or holiday operations, unanticipated changes in operative plan during surgery, and emergency operations. Body mass index was not associated with miscounts. Surveys completed by participating surgical staff suggested high confidence in the RFDS for prevention of RSIs. CONCLUSIONS: The incorporation of the RFDS assisted in the resolution of a near-miss event (1 of 2,285) not detected by manual counting protocols and assisted in the resolution of 35 surgical-sponge miscounts. No known RSIs occurred during the study period. Risk factors for miscounts were identified and can help identify at-risk surgical populations.
