Resources on lymphedema surgery: How effective are they for patients?

Online patient education materials (PEMs) on lymphedema surgery were assessed for quality, readability, and content. A total of 37 PEMs were identified, primarily authored by academic/medical organizations. Readability scores indicated materials were difficult to read, with an average Flesch-Kincaid Grade Level of 10.4. PEM Assessment Tools showed acceptable understandability (72.3%) but poor actionability (28.5%). PEMs often lacked information on surgical risks, postoperative care, and long-term follow-up. Simplifying language and adding visual aids could improve PEM effectiveness.

The Risk of Medication-Related Osteonecrosis of the Jaw in Children: Guidance for Antiresorptive Use in Pediatric Patients.

BACKGROUND: Antiresorptive targeted cancer therapies, such as denosumab and bisphosphonates, are used in adults, but their application in pediatric cancer is more recent. Side effects such as osteonecrosis of the jaw (ONJ) observed in adults have curtailed use of these medications in the pediatric population. PURPOSE: This study assesses the frequency of ONJ, other side effects, and the indications for use of denosumab versus bisphosphonates in pediatric subjects. STUDY DESIGN, SETTING, SAMPLE: A retrospective cohort study of pediatric subjects who underwent bisphosphonate or denosumab therapy at our institution from 2007-2023 was conducted. Subjects aged ≥ 18 years at therapy initiation were excluded. INDEPENDENT VARIABLE: The independent variable was antiresorptive therapy divided into 2 groups, treatment with intravenous bisphosphonates or denosumab. MAIN OUTCOME VARIABLE(S): Primary outcomes were development of bisphosphonate-related and denosumab-related ONJ. Secondary outcomes included additional side effects. COVARIATES: ONJ risk factors, subject demographics, indications for use, timing, duration, and cumulative dose of antiresorptive therapy were abstracted. ANALYSES: Univariate and bivariate statistics were computed to describe the sample and measure associations between antiresorptive therapy and outcomes. P values < .05 conferred statistical significance. RESULTS: The sample was composed of 178 subjects with a mean age of 11.7 ± 6.1 years. There were 14 (7.9%) and 164 (92.1%) subjects treated with denosumab and bisphosphonate therapies, respectively. There were 0 cases of ONJ across all subjects. The most common indication for treatment was adjuvant targeted therapy for aggressive tumors and malignancy (39.3%) followed by osteoporosis (14.6%). Subjects treated with denosumab had higher frequencies of hypercalcemia and severe bone pain than subjects treated with bisphosphonates, 28.6% versus 1.2% (P < .001) and 14.3% versus 0.00% (P < .001), respectively. CONCLUSION AND RELEVANCE: While invasive dental procedures are ideally performed before antiresorptive treatment, our data suggest that bisphosphonates may be used safely in the pediatric population with low concern for ONJ. Our data also demonstrated bisphosphonates may have a more tolerable side effect profile than denosumab. If the perceived benefits are similar, we recommend using bisphosphonates as first-line therapy in children while reserving denosumab for refractory cases. Future studies will help determine long-term side effects and differences in efficacies of these medications.

Skeletal and Soft Tissue Surgeries in the Long-term Management of Patients With Syndromic Craniosynostosis: A 20-Year Review.

BACKGROUND: Soft tissue procedures are often crucial for normalizing the long-term facial appearance in patients with syndromic craniosynostosis, yet they are underrepresented in the literature and existing treatment algorithms. This study evaluated secondary soft tissue surgeries in relation to skeletal operations in patients with syndromic craniosynostosis. METHODS: A retrospective review evaluated patients with syndromic craniosynostosis treated at a tertiary children's hospital from 2003 to 2023. Craniofacial skeletal and soft tissue procedures were assessed for timing and frequency. Skeletal surgeries included redo fronto-orbital advancements, monobloc advancement/distraction ± facial bipartition, and LeFort III or III/I advancement/distraction. Soft tissue surgeries encompassed oculoplastic procedures, scalp reconstruction, fat grafting, and septorhinoplasty. RESULTS: Of 106 patients with syndromic craniosynostosis, 57 (57.8%) underwent ≥1 secondary skeletal operation, and 101 (95.3%) underwent ≥1 soft tissue procedures, averaging 3.7 ± 3.3 soft tissue procedures per patient. Patients who underwent secondary forehead advancement had significantly higher rates of subsequent lateral canthopexy (71.4% vs 25.6, P < 0.001), ptosis reconstruction (17.9% vs 7.7%, P = 0.025), and frontotemporal fat grafting (50.0% vs 15.4%, P < 0.001) than those who did not. Patients who underwent midface advancement surgery had significantly higher rates of subsequent lateral canthopexy (65.4% vs 11.1%, P < 0.001), medial canthopexy (7.7% vs 0.0%, P = 0.038), scalp reconstruction (36.5% vs 16.7%, P = 0.020), frontotemporal fat grafting (34.6% vs 14.8%, P = 0.018), malar fat grafting (11.5% vs 0.0%, P = 0.010), and septorhinoplasty (26.9% vs 1.9%, P < 0.001) than those who did not. Specifically, LeFort III or III/I advancement/distractions were significantly associated with higher rates of subsequent septorhinoplasties (33.3% vs 1.6%, P < 0.001). The mean follow-up was 10.2 ± 7.0 years. CONCLUSIONS: This study revealed an intricate interplay between skeletal and soft tissue surgery in patients with syndromic craniosynostosis. Exploring techniques to reduce the need for further corrective surgery and anticipating necessary secondary interventions may improve patient counseling and outcomes.

Guidance for Circumflex Scapular Artery Flap Utilization in Pediatric Reconstruction.

BACKGROUND: The circumflex scapular artery (CSA) flap system, consisting of scapular, parascapular, and chimeric flaps, is useful for pediatric reconstruction in many anatomical locations. The objectives of this case series are to offer insights into our decision-making process for selecting the CSA flap in particular pediatric reconstructive cases and to establish a framework for choosing a scapular or parascapular skin paddle. We also aim to emphasize important technical considerations of CSA flap utilization in pediatric patients. METHODS: Pediatric reconstruction with CSA flaps performed at our institution between 2006-2022 was retrospectively reviewed. Patient demographics, indications, flap characteristics, complications, and operative data were abstracted. Functional donor site morbidity was assessed through postoperative physical examinations. Unpaired t test analyzed scapular versus parascapular flap size. RESULTS: Eleven CSA flaps were successfully performed in 10 patients (6 scapular and 5 parascapular flaps). Patient ages ranged from 2 to 17 years. Scapular fasciocutaneous free flaps (n = 4) were performed in patients' ages 2-5 years for hand and forearm scar contractures. Two pedicled scapular flaps were performed for a single patient for bilateral axillary hidradenitis suppurativa. The 5 parascapular flaps were performed in patients' ages 2-14 years for calcaneus and forearm avulsion wounds and reconstruction after resection of hidradenitis suppurativa, nevus sebaceous, and Ewing sarcoma. In the sarcoma resection case, a chimeric flap with latissimus dorsi was employed. Average flap size was 101.6 ± 87.3 cm2 (range: 18-300 cm2). Parascapular flaps were significantly larger than scapular flaps (156.60 ± 105.84 cm2 vs 55.83 ± 26.97 cm2, P = 0.0495). Overall, 3 complications occurred (27.3% of cases) including venous congestion (n = 2) and wound dehiscence (n = 1). There were no reported cases of compromised shoulder function at 1.9 ± 2.5-year follow-up. The successful reconstruction rate for scapular, parascapular, and chimeric flaps was 100%. CONCLUSIONS: The CSA flap treated a wide variety of indications demonstrating the flap's attributes: large vessel caliber, wide arc of rotation, reliable vascular anatomy, minimal donor site morbidity, and ability to incorporate bone and muscle. Our cases also highlight important pediatric considerations such as vascular mismatch and limited scapular bone stock. We recommend selection of the parascapular over the scapular flap with reconstruction of larger, complex defects given its ability to be harvested with a large skin paddle.

Polysomnogram Findings and Psychosocial and Academic Concerns in Children With Cleft Palate With or Without Cleft Lip.

Children born with a cleft palate with or without a cleft lip (CP±L) are at risk for sleep-disordered breathing, particularly obstructive sleep apnea (OSA). While OSA and CP±L have both been associated with higher risk for psychosocial and academic concerns, their combined risk has been understudied. This paper aimed to describe polysomnography findings and psychosocial and academic concerns among children with isolated (iCP±L) and syndrome-associated (sCP±L) clefts who had undergone primary palatoplasty. Medical records were reviewed from 2004 to 2022 for demographics, medical history, polysomnography results, and family-reported psychosocial and academic variables. Of the 694 patients with CP±L who had a palatoplasty, 147 had a polysomnogram and 82 had at least one follow-up polysomnogram. Across time points, only 19% to 27% of participants had normal polysomnograms and the most frequent finding was mild OSA for 30% to 35% of patients. For children with iCP±L, more frequent oxygen desaturations were significantly associated with receiving special education services and family-reported academic concerns and OSA was associated with a history of receiving mental health services. Children with sCP±L had a significantly higher Obstructive Apnea-Hypopnea Index and a greater proportion of all-day special education classroom placements relative to youth with iCP±L. Study results suggest that cleft providers should monitor for OSA and sleep-disordered breathing symptoms, collaborate with pulmonologists for evaluation and treatment of sleep concerns, and address possible sleep-associated psychosocial and academic issues.

Expanding Accessibility in Cleft Care: The Role of Artificial Intelligence in Improving Literacy of Alveolar Bone Grafting Information.

OBJECTIVE: The American Medical Association (AMA) recommends patient education materials (PEMs) be written at or below a sixth grade reading level. This study seeks to determine the quality, readability, and content of available alveolar bone grafting (ABG) PEMs and determine if artificial intelligence can improve PEM readability. DESIGN: Review of free online PEMs. SETTING: Online ABG PEMs were retrieved from different authoring body types (hospital/academic center, medical society, or private practice). PATIENTS, PARTICIPANTS: None. INTERVENTIONS: Content was assessed by screening PEMs for specific ABG-related topics. Quality was evaluated with the Patient Education Material Assessment Tool (PEMAT), which has measures of understandability and actionability. Open-access readability software (WebFX) determined readability with Flesch Reading Ease, Flesch-Kincaid Grade Level, and Gunning-Fog Index. PEMs were rewritten with ChatGPT, and readability metrics were reassessed. MAIN OUTCOME MEASURE(S): Quality, readability, and content of ABG PEMs. RESULTS: 34 PEMs were analyzed. Regarding quality, the average PEMAT-understandability score was 67.0 ± 16.2%, almost at the minimum acceptable score of 70.0% (p = 0.281). The average PEMAT-actionability score was low at 33.0 ± 24.1%. Regarding readability, the average Flesch Reading Ease score was 64.6 ± 12.8, categorized as "standard/plain English." The average Flesch-Kincaid Grade Level was 8.0 ± 2.3, significantly higher than AMA recommendations (p < 0.0001). PEM rewriting with ChatGPT improved Flesch-Kincaid Grade Level to 6.1 ± 1.3 (p < 0.0001). CONCLUSIONS: Available ABG PEMs are above the recommended reading level, yet ChatGPT can improve PEM readability. Future studies should improve areas of ABG PEMs that are most lacking, such as actionability.

Orthognathic Surgery Rates in Furlow Double-Opposing Z-Plasty Versus Straight-Line Repair: A Review of Three Decades of Experience.

OBJECTIVE: The influence of different surgical techniques on maxillary growth remains unclear. This study investigates the long-term impact of Furlow double-opposing Z-plasty versus straight-line repair (SLR) techniques on midface growth and subsequent orthognathic surgery. DESIGN: Retrospective cohort study. SETTING: Tertiary children's hospital. PATIENTS/PARTICIPANTS: This study evaluated patients who underwent primary palatoplasty with Furlow or SLR techniques from 1994-2023. Patients were >14 years old at their most recent follow-up. INTERVENTIONS: No interventions were performed. MAIN OUTCOME MEASURE(S): Primary outcomes were orthognathic surgery and orthognathic surgery recommendation rates to correct midface hypoplasia (MFH). Cephalometrics at the time of orthognathic surgery recommendation were traced to validate MFH. RESULTS: In total, 1857 patients underwent palatoplasty, of which 335 met inclusion criteria (49 SLR, 286 Furlow). Average age at last follow-up was 18.5±2.6 years. Patients who underwent Furlow versus SLR showed no significant difference in orthognathic surgery rates (p=0.428) or recommendation for orthognathic surgery rates (p=0.900). Patients recommended to undergo orthognathic surgery had more negative ANB angles (p<0.001) and smaller SNA angles (p<0.001) than patients not recommended for orthognathic surgery, demonstrating maxillary hypoplasia. Upon multivariate regression, patients with Veau III and IV clefts had an increased need for orthognathic surgery, p=0.047 and p=0.008, respectively. CONCLUSIONS: Our findings suggest that higher cleft severity contributes to future orthognathic surgery. However, palatoplasty technique did not influence orthognathic surgery rates. Our results provide valuable data when surgeons are considering the impact of palatoplasty technique on sagittal growth restriction.

The Forgotten Flap: The Pedicled Trapezius Flap's Utility in Pediatric Head and Neck Reconstruction-A Systematic Review.

BACKGROUND: When free tissue transfer is precluded or undesired, the pedicled trapezius flap is a viable alternative for adults requiring complex head and neck (H&N) defect reconstruction. However, the application of this flap in pediatric reconstruction is underexplored. This systematic review aimed to describe the use of the pedicled trapezius flap and investigate its efficacy in pediatric H&N reconstruction. METHODS: A systematic review was performed using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Articles describing the trapezius flap for H&N reconstruction in pediatric patients were included. Patient demographics, surgical indications, wound characteristics, flap characteristics, complications, and functional outcomes were abstracted. RESULTS: A systematic review identified 22 articles for inclusion. Studies mainly consisted of case reports (n = 11) and case series (n = 8). In total, 67 pedicled trapezius flaps were successfully performed for H&N reconstruction in 63 patients. The most common surgical indications included burn scar contractures (n = 46, 73.0%) and chronic wounds secondary to H&N masses (n = 9, 14.3%). Defects were most commonly located in the neck (n = 28, 41.8%). The mean flap area and arc of rotation were 326.4 ± 241.7 cm2 and 157.6 ± 33.2 degrees, respectively. Most flaps were myocutaneous (n = 48, 71.6%) and based on the dorsal scapular artery (n = 32, 47.8%). Complications occurred in 10 (14.9%) flaps. The flap's survival rate was 100% (n = 67). No instances of functional donor site morbidity were reported. The mean follow-up was 2.2 ± 1.8 years. CONCLUSION: This systematic review demonstrated the reliability of the pedicled trapezius flap in pediatric H&N reconstruction, with a low complication rate, no reports of functional donor site morbidity, and a 100% flap survival rate. The flap's substantial surface area, bulk, and arc of rotation contribute to its efficacy in covering soft tissue defects ranging from the proximal neck to the vertex of the scalp. The pedicled trapezius flap is a viable option for pediatric H&N reconstruction.

Assessment of Cranial Sexual Dimorphism Using 3D Reconstruction: Implications for Gender-Affirming Surgery.

BACKGROUND: As more centers offer gender-affirming procedures, dissemination of best practices is critical to ensuring quality care. This study is the first to use advanced 3-dimensional visualization software to characterize cranial differences between natal males and females, as they relate to planning for facial gender-affirming operations. MATERIALS AND METHODS: A retrospective analysis was conducted on randomly selected patients with facial computed tomography imaging performed at a single institution between February 2020 and July 2021. Patients with acquired bony deformity on computed tomography or documented history of hormone replacement therapy were excluded. The images were retrieved and analyzed using advanced 3-dimensional visualization software (Vitrea). Independent sample t tests were performed to analyze variation in typically sexually dimorphic facial features between natal males and females. RESULTS: We identified 50 patients (25 natal males and 25 natal females) who met the inclusion criteria. Ages ranged from 19 to 91. Natal males were found to have significantly greater frontosellar distances (difference between means, SEM: 2.7±1.2; P =0.03) and mandible volumes (difference between means, SEM: 14.0±4.2; P =0.002) than natal females. Statistical analysis revealed no significant differences in gonial angle, chin width, nasofrontal angle, or nasolabial angle between natal males and females. CONCLUSION: In this diverse sample of natal males and females, statistical analysis revealed that the sexually dimorphic facial characteristics most relevant to the planning of facial gender-affirming surgery are frontosellar distance and mandible volume. When planning facial gender-affirming surgery, we recommend that these characteristics be considered to achieve optimum results.

Tympanostomy Tubes: Are They Necessary? A Systematic Review on Implementation in Cleft Care.

OBJECTIVE: To understand the indication for and the effects of early ventilation tube insertion (VTI) on hearing and speech for patients with cleft lip and/or palate (CLP). DESIGN: We conducted a Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA)-guided systematic review of relevant literature. SETTING: Setting varied by geographical location and level of clinical care across studies. PATIENTS, PARTICIPANTS: Patients with CLP who underwent VTI were included. INTERVENTIONS: No interventions were performed. MAIN OUTCOME MEASURE(S): Primary outcome measures were hearing and speech following VTI. Secondary outcome measures were tube-related and middle ear complications. Early VTI occurred before or at time of palatoplasty while late VTI occurred after palatoplasty. RESULTS: Twenty-three articles met inclusion criteria. Articles varied among study design, outcome measures, sample size, follow-up, and quality. Few studies demonstrated support for early VTI. Many studies reported no difference in hearing or speech between early and late VTI. Others reported worse outcomes, greater likelihood of complications, or needing repeat VTI following early tympanostomy placement. Several studies had significant limitations, including confounding variables, small sample size, or not reporting on our primary outcome. CONCLUSIONS: No consistency was found regarding which patients would benefit most from early VTI. Given the aforementioned variability and sub-optimal methodologies, additional studies are warranted to provide stronger evidence regarding VTI timing in cleft care.

Lessons Learned from a Single Institution's Eight Years of Experience with Early Cleft Lip Repair.

Background and Objectives: The traditional approach in managing wide cleft lip deformities involves presurgical nasoalveolar molding (NAM) therapy followed by surgical cleft lip repair between three and six months of age. This institution has implemented an early cleft lip repair (ECLR) protocol where infants undergo primary cleft lip repair between two and five weeks of age without NAM. This study aims to present this institution's ECLR repair protocol over the past eight years from 188 consecutive patients with unilateral or bilateral CL/P deformity. Materials and Methods: Retrospective review was conducted at Children's Hospital Los Angeles evaluating patients who underwent ECLR before three months of age and were classified as American Society of Anesthesiologists (ASA) class I or II from 2015-2022. Anthropometric analysis was performed, and pre- and postoperative photographs were evaluated to assess nasal and lip symmetry. Results: The average age at cleft lip repair after correcting for gestational age was 1.0 ± 0.5 months. Mean operative and anesthetic times were 120.3 ± 33.0 min and 189.4 ± 35.4, respectively. Only 2.1% (4/188) of patients had postoperative complications. Lip revision rates were 11.4% (20/175) and 15.4% (2/13) for unilateral and bilateral repairs, respectively, most of which were minor in severity (16/22, 72.7%). Postoperative anthropometric measurements demonstrated significant improvements in nasal and lip symmetry (p < 0.001). Conclusions: This analysis demonstrates the safety and efficacy of ECLR in correcting all unilateral cleft lip and nasal deformities of patients who were ASA classes I or II. At this institution, ECLR has minimized the need for NAM, which is now reserved for patients with bilateral cleft lip, late presentation, or comorbidities that preclude them from early repair. ECLR serves as a valuable option for patients with a wide range of cleft severity while reducing the burden of care.

The Emerging Role of GLP-1 Agonists in Burn Care: What Do We Know?

Glucagon-like peptide-1 (GLP-1) agonists mimic the action of GLP-1, a hormone that regulates blood glucose levels via stimulation of insulin release and inhibition of glucagon secretion. After burn, the current literature suggests that the use of GLP-1 agonists results in less insulin dependence with similar glucose control and hypoglycemic events to patients receiving a basal-bolus insulin regimen. GLP-1 agonists may also promote wound healing through various mechanisms including angiogenesis and improved keratinocyte migration. Despite the potential benefits, GLP-1 agonists reduce gastrointestinal motility which impacts their widespread adoption in burn care. This dysmotility can result in inadequate nutrition delivery, unintentional weight loss, and is a potential aspiration risk. The net impact of these medications on burn patients is unclear. Given their potential to demonstrate the safety, efficacy, and optimal dosing of various GLP-1 agonists in acute burn management.

Simulated outcomes for durotomy repair in minimally invasive spine surgery.

Minimally invasive spine surgery (MISS) is increasingly performed using endoscopic and microscopic visualization, and the captured video can be used for surgical education and development of predictive artificial intelligence (AI) models. Video datasets depicting adverse event management are also valuable, as predictive models not exposed to adverse events may exhibit poor performance when these occur. Given that no dedicated spine surgery video datasets for AI model development are publicly available, we introduce Simulated Outcomes for Durotomy Repair in Minimally Invasive Spine Surgery (SOSpine). A validated MISS cadaveric dural repair simulator was used to educate neurosurgery residents, and surgical microscope video recordings were paired with outcome data. Objects including durotomy, needle, grasper, needle driver, and nerve hook were then annotated. Altogether, SOSpine contains 15,698 frames with 53,238 annotations and associated durotomy repair outcomes. For validation, an AI model was fine-tuned on SOSpine video and detected surgical instruments with a mean average precision of 0.77. In summary, SOSpine depicts spine surgeons managing a common complication, providing opportunities to develop surgical AI models.

Sociodemographic Factors Associated with Delayed Presentation in Craniosynostosis Surgery at a Tertiary Children's Hospital.

Background: Craniosynostosis is a common diagnosis requiring early referral to a pediatric plastic surgeon; however, disparities in healthcare may influence presentation timing and affect treatment options and outcomes. This study aimed to explore sociodemographic factors contributing to delay in craniosynostosis surgical consultation. Methods: A retrospective cohort study of 694 California-based craniosynostosis patients at a tertiary children's hospital was performed from 2006 to 2023. State-specific Area Deprivation Index (ADI) and distance to the hospital were calculated using ZIP codes. Multivariate linear and logistic regressions considered race, insurance type, syndromic status, suture type, and ZIP code-based socioeconomic factors. Results: Median age of presentation was 4.5 [interquartile range: 2.6-7.6] months with racial/ethnic breakdown of Hispanic/Latinx (41.2%), White (23.6%), Asian (3.7%), Black/African American (2.0%), or other/unreported (29.5%) with 58.4% having public insurance and an average distance to the hospital of 48.3 km. Median ADI was 5.4 [interquartile range: 4.0-7.1]. By linear regression, public insurance (P < 0.001) and higher ADI decile (P < 0.001) independently contributed to an older age of presentation. Patients with public insurance (odds ratio 1.90; P = 0.002) were more likely to present after 4 months of age. Conclusions: Patients who had public insurance or resided in more disadvantaged areas presented later for craniosynostosis surgical consultation. Eliminating disparities in these populations ensures more equitable access to surgical options and can improve patient outcomes.

STOPTHEBURN: A Randomized Controlled Trial of Death Cafés for Burnout Prevention in Intensive Care Unit Employees.

Rationale: Effective interventions to prevent burnout among intensive care unit (ICU) clinicians are urgently needed. Death cafés, group discussions about death, build a sense of community and create a space for reflection on distressing events. Objective: To assess whether participation in regular death cafés can prevent burnout in ICU clinicians (physicians, nurses, pharmacists, therapists). Methods: A randomized clinical trial was conducted from July 2020 to December 2022 in 10 ICUs in Louisiana. Subjects were randomized to attend four psychotherapist-facilitated virtual death cafés or to a control arm. The primary outcome was burnout defined by the Maslach Burnout Inventory-Human Services Survey at 6 months. Depression and anxiety scores were measured, as were qualitative data on stressors, coping, and death café experience. Results: Among 340 clinicians who were screened and gave consent (171 physicians, 169 nonphysicians), 251 participated (mean age, 31.0 ± 6.8 years; 63% female; 72% White; 37% nurses, 27% residents, 25% interns, 11% other). Burnout prevalence was 19% at baseline. Of 136 participants who completed the 6-month follow-up, no significant differences were found between intervention and control for the primary outcome (18% vs. 25%; unadjusted odds ratio, 0.64; 95% confidence interval, 0.26-1.57; P = 0.33). There were no differences in anxiety or depression. Notably, the study was limited by an inability to achieve target enrollment and a high attrition rate (46%). Conclusions: Virtual death cafés were unable to reduce burnout, although the study was underpowered to detect differences between groups. Clinical trial registered with clinicaltrials.gov (NCT04347811).

Utility of the Simulated Outcomes Following Carotid Artery Laceration Video Data Set for Machine Learning Applications.

Importance: Surgical data scientists lack video data sets that depict adverse events, which may affect model generalizability and introduce bias. Hemorrhage may be particularly challenging for computer vision-based models because blood obscures the scene. Objective: To assess the utility of the Simulated Outcomes Following Carotid Artery Laceration (SOCAL)-a publicly available surgical video data set of hemorrhage complication management with instrument annotations and task outcomes-to provide benchmarks for surgical data science techniques, including computer vision instrument detection, instrument use metrics and outcome associations, and validation of a SOCAL-trained neural network using real operative video. Design, Setting, and Participants: For this quailty improvement study, a total of 75 surgeons with 1 to 30 years' experience (mean, 7 years) were filmed from January 1, 2017, to December 31, 2020, managing catastrophic surgical hemorrhage in a high-fidelity cadaveric training exercise at nationwide training courses. Videos were annotated from January 1 to June 30, 2021. Interventions: Surgeons received expert coaching between 2 trials. Main Outcomes and Measures: Hemostasis within 5 minutes (task success, dichotomous), time to hemostasis (in seconds), and blood loss (in milliliters) were recorded. Deep neural networks (DNNs) were trained to detect surgical instruments in view. Model performance was measured using mean average precision (mAP), sensitivity, and positive predictive value. Results: SOCAL contains 31 443 frames with 65 071 surgical instrument annotations from 147 trials with associated surgeon demographic characteristics, time to hemostasis, and recorded blood loss for each trial. Computer vision-based instrument detection methods using DNNs trained on SOCAL achieved a mAP of 0.67 overall and 0.91 for the most common surgical instrument (suction). Hemorrhage control challenges standard object detectors: detection of some surgical instruments remained poor (mAP, 0.25). On real intraoperative video, the model achieved a sensitivity of 0.77 and a positive predictive value of 0.96. Instrument use metrics derived from the SOCAL video were significantly associated with performance (blood loss). Conclusions and Relevance: Hemorrhage control is a high-stakes adverse event that poses unique challenges for video analysis, but no data sets of hemorrhage control exist. The use of SOCAL, the first data set to depict hemorrhage control, allows the benchmarking of data science applications, including object detection, performance metric development, and identification of metrics associated with outcomes. In the future, SOCAL may be used to build and validate surgical data science models.

Use of surgical video-based automated performance metrics to predict blood loss and success of simulated vascular injury control in neurosurgery: a pilot study.

OBJECTIVE: Experts can assess surgeon skill using surgical video, but a limited number of expert surgeons are available. Automated performance metrics (APMs) are a promising alternative but have not been created from operative videos in neurosurgery to date. The authors aimed to evaluate whether video-based APMs can predict task success and blood loss during endonasal endoscopic surgery in a validated cadaveric simulator of vascular injury of the internal carotid artery. METHODS: Videos of cadaveric simulation trials by 73 neurosurgeons and otorhinolaryngologists were analyzed and manually annotated with bounding boxes to identify the surgical instruments in the frame. APMs in five domains were defined-instrument usage, time-to-phase, instrument disappearance, instrument movement, and instrument interactions-on the basis of expert analysis and task-specific surgical progressions. Bounding-box data of instrument position were then used to generate APMs for each trial. Multivariate linear regression was used to test for the associations between APMs and blood loss and task success (hemorrhage control in less than 5 minutes). The APMs of 93 successful trials were compared with the APMs of 49 unsuccessful trials. RESULTS: In total, 29,151 frames of surgical video were annotated. Successful simulation trials had superior APMs in each domain, including proportionately more time spent with the key instruments in view (p < 0.001) and less time without hemorrhage control (p = 0.002). APMs in all domains improved in subsequent trials after the participants received personalized expert instruction. Attending surgeons had superior instrument usage, time-to-phase, and instrument disappearance metrics compared with resident surgeons (p < 0.01). APMs predicted surgeon performance better than surgeon training level or prior experience. A regression model that included APMs predicted blood loss with an R2 value of 0.87 (p < 0.001). CONCLUSIONS: Video-based APMs were superior predictors of simulation trial success and blood loss than surgeon characteristics such as case volume and attending status. Surgeon educators can use APMs to assess competency, quantify performance, and provide actionable, structured feedback in order to improve patient outcomes. Validation of APMs provides a benchmark for further development of fully automated video assessment pipelines that utilize machine learning and computer vision.

Death Cafés for prevention of burnout in intensive care unit employees: study protocol for a randomized controlled trial (STOPTHEBURN).

BACKGROUND: Burnout is an occupational syndrome that leads to mental health problems, job turnover, and patient safety events. Those caring for critically ill patients are especially susceptible due to high patient mortality, long hours, and regular encounters with trauma and ethical issues. Interventions to prevent burnout in this population are needed. Preliminary studies suggest debriefing sessions may reduce burnout. This study aims to assess whether participation in regular debriefing can prevent burnout in intensive care unit (ICU) clinicians. METHODS: A randomized controlled trial will be conducted in two large academic medical centers. Two hundred ICU clinicians will be recruited with target enrollment of 100 physicians and 100 non-physicians (nurses, pharmacists, therapists). Participants must have worked in the ICU for the equivalent of at least 1 full time work week in the preceding 4 weeks. Enrolled subjects will be randomized to virtually attend biweekly debriefing sessions facilitated by a psychotherapist for 3 months or to a control arm without sessions. Our debriefs are modeled after Death Cafés, which are informal discussions focusing on death, dying, loss, grief, and illness. These sessions allow for reflection on distressing events and offer community and collaboration among hospital employees outside of work. The primary outcome is clinician burnout as measured by the Maslach Burnout Inventory (MBI) Score. Secondary outcomes include depression and anxiety, as measured by the Patient Health Questionnaire 8 (PHQ-8) and Generalized Anxiety Disorder 7-item scale (GAD-7), respectively. Questionnaires will be administered prior to the intervention, at 1 month, at 3 months, and at 6 months after enrollment. These values will be compared between groups temporally. Qualitative feedback will also be collected and analyzed. DISCUSSION: With ICU clinician burnout rates exceeding 50%, Death Café debriefing sessions may prove to be an effective tool to avert this debilitating syndrome. With COVID-19 limiting social interactions and overloading ICUs worldwide, the virtual administration of the Death Café for ICU clinicians provides an innovative strategy to potentially mitigate burnout in this vulnerable population.
