Factors Affecting Surgical Decision-making-A Qualitative Study

Surgical site soft tissue thickness as a predictor of complications following arthroplasty

Appreciation of soft-tissue thickness (STT) at surgical sites is an increasingly recognized aspect of arthroplasty procedures as it may potentially impacting postoperative outcomes. Recent research has focused on the predictive value of preoperative STT measurements for complications following various forms of arthroplasty, particularly infections, across procedures such as total knee, hip, shoulder, and ankle replacements. Several studies have indicated that increased STT is associated with a higher risk of complications, including infection and wound healing issues. The assessment of STT before surgery could play a crucial role in identifying patients at a higher risk of complications and may be instrumental in guiding preoperative planning to optimize outcomes in arthroplasty procedures. Standardized measurement techniques and further research are essential to enhance the reliability and clinical utility of STT assessment for arthroplasty surgery.

Endoscopic endonasal approach to the nerves of the pterygopalatine fossa: a detailed cadaveric anatomical study

PURPOSE

The endoscopic endonasal approach offers a safe, reliable, and minimally invasive method to access the pterygopalatine fossa. In this study, we provide a detailed anatomical exploration of the pterygopalatine fossa, with a particular focus on the nerves and their spatial relationships to key endoscopic landmarks.

METHODS

A total of 12 pterygopalatine fossae from six formalin-fixed cadaveric heads (five female, one male) were dissected using both endoscopic approach and anatomical microscopic dissection to measure the lengths, diameters, and anatomical relationships of the nerves and arteries.

RESULTS

The maxillary nerve measured 15.93 ± 6.19 mm in length and 3.96 ± 0.69 mm in diameter, while infraorbital nerve measured 24.4 ± 4.38 mm in length and 3.00 ± 0.71 mm in diameter. The greater palatine nerve measured 13.15 ± 4.25 mm in length and 2.70 ± 0.39 mm in diameter. The Vidian nerve measured 16.78 ± 1.18 mm in length and 2.15 ± 0.51 mm in diameter. The pterygopalatine ganglion had a width of 4.59 ± 1.16 mm and a height of 5.18 ± 1.63 mm. The infraorbital nerves were primarily located lateral to the infraorbital artery, while the greater palatine nerves were typically found medial to the descending palatine arteries.

CONCLUSION

Our findings indicate that the maxillary, infraorbital, and greater palatine nerves, together with the pterygopalatine ganglion, are key landmarks for defining the surgical boundaries of the pterygopalatine fossa. These insights are expected to enhance the safety and precision of surgical interventions in this complex anatomical region, ultimately improving patient outcomes.

Protective ileostomy creation after anterior resection of the rectum (PICARR): a decision-making exploring international survey

In our previous survey of experts, surgeon's decision-making process (DMP) about protective ileostomy (PI) creation after anterior resection was investigated. Based on our previous data, a multiple choice questionnaire has been developed. The aim is to perform a quantitative analysis of the results obtained from an international survey and to describe the clinical practice worldwide. Ten questions were related to participants' demographics and, 20 questions (of which 17 Likert scale questions) investigated the DMP regarding PI creation. To evaluate the tendency of the answers in the Likert-type questions, the mean of the answers obtained was compared with the mean point of the Likert scale. The survey was completed by 1019 physicians. Neoadjuvant chemoradiotherapy and distance of the anastomosis from the anal verge ≤ 10 cm were each considered alone sufficient to justify creation of a PI, with statistically significant differences in comparison to the mean point of the scales in (p =  < 0.0001 in both cases). Total Mesorectal Excision alone was not considered a factor sufficient to create a PI (p = 0.416). Most of the participants agree to define their approach to create a PI "tailored" to patients' risk factors (p =  < 0.0001) and "influenced by my experience" in case of patients with low/moderate risk of anastomotic leakage (p =  < 0.0001). This study provides useful insights on the worldwide clinical practice regarding creation of PI following anterior resection. Given the lack of standardization and evidence-based guidelines, this analysis may be helpful to assist surgeons' practice.

The Centre for Evidence-Based Orthopaedics Tool for the Implementation of Evidence-Based Practice

Introduction Updating practices can be challenging in evidence-based practice when integrating the evidence, clinical expertise, and patient values and preferences. Implementing evidence-based practice requires individual, collective, and organizational behavioral changes. Effective behavior change interventions are necessary to facilitate the implementation of new evidence. We propose a tool to facilitate the implementation of evidence in clinical decision-making by changing healthcare providers' behaviors. Methods The Centre for Evidence-Based Orthopaedics (CEBO) tool was developed to bridge the gap between evidence and practice in a hospital department. The development process follows a Plan-Do-Study-Act (PDSA) structure and is based on the COM-B model (Capability, Opportunity, Motivation, Behavior) and the Theoretical Domains Framework (TDF), which recognize that effective behavior change necessitates addressing factors at both individual and organizational levels. The CEBO tool consists of four phases, guiding the process from identifying an evidence-practice gap to evaluating behavioral changes following implementation. Results We applied the CEBO tool to two surgical cases, which led to substantial behavioral changes in orthopedic surgeons' treatment choices. Our findings indicate that the CEBO tool is feasible and can influence surgeons' behaviors to align more closely with the best available evidence. Conclusion The CEBO tool helps align practice with the best available evidence. Although implementing new practices effectively is time-consuming, it seems achievable with the CEBO tool. Substantial behavioral changes were observed among surgeons in both cases.

Impact of bone quality on surgical decision-making in total hip arthroplasty: a qualitative analysis in the UK

INTRODUCTION

For total hip arthroplasty (THA) to be successful, surgeons need to make several decisions ranging from implant choice to impaction force. It is unclear, however, whether and how bone quality affects surgeon's decision-making and how surgeons evaluate bone quality.

OBJECTIVES

This inductive/deductive qualitative hybrid study aims to explore the impact of bone quality on the decision-making of surgeons performing elective primary THA. This study will evaluate: (1) whether surgeons consider bone quality as an important factor for surgical decision-making; (2) how bone quality influences surgical decision-making; and (3) how surgeons assess bone quality preoperatively and intraoperatively.

DESIGN

This is a qualitative study, involving inductive/deductive hybrid thematic analysis.

SETTING

Semistructured interviews were conducted virtually via Microsoft Teams and on hospital premises.

PARTICIPANTS

Purposive and snowball sampling methods were used to recruit consultant orthopaedic surgeons specialised in elective lower limb arthroplasty.

RESULTS

10 surgeons from eight centres in the UK were interviewed. Thematic saturation was achieved after eight interviews. 5 main themes and 13 subthemes were identified. Bone quality impacted decisions around preoperative planning, surgical procedure, implant choice, concerns of iatrogenic injury and hip biomechanics. Many surgeons (7/10) described changing surgical procedure based on their intraoperative assessment of bone quality. There was consensus that cemented femoral fixation is superior in patients with poor bone quality and on the importance of assessing radiographs preoperatively. There was, however, a lack of consensus on optimal acetabular fixation method, the radiographs metrics used to measure bone quality and attitudes towards current guidelines.

CONCLUSIONS

Bone quality has a significant impact on the decision-making of experienced arthroplasty surgeons, though there are significant limitations and divergence in current methods of assessing bone quality. Further work to identify intraoperative and preoperative imaging metrics that correlate with bone mechanical properties could enhance surgical decision-making.

Factors influencing UK arthroplasty surgeons' decision-making between total and medial unicompartmental knee surgery: A vignette-based behavioural experiment

Purpose

Surgical options for end-stage knee osteoarthritis (OA) include total and medial unicompartmental knee replacement (TKR and UKR). Deciding which surgery to perform is complex and ill-defined, yet it has important implications for patients and the health service. The study aimed to identify clinical and surgeon factors predicting surgeons' preferences.

Methods

Based on a preliminary survey of 162 UK surgeons, we identified clinical features frequently considered when deciding between TKR and UKR. By systematically varying patient age, obesity, site of pain, anaesthetic risk and anterior cruciate ligament (ACL) integrity, we constructed 32 clinical vignettes. We used these in a new survey, where surgeons indicated which surgery they would recommend on an 11-point rating scale with end points anchored at 'definitely TKR' and 'definitely medial UKR'. Data were analysed with mixed-effects linear regressions.

Results

Eighty-three UK arthroplasty surgeons completed the vignettes. Preference for UKR over TKR was significantly lower for patients over 50 years (b = -0.57 [-0.82 to -0.33], p < 0.001) with abnormal ACL (b = -1.93 [-2.17 to -1.68], p < 0.001) and severe systemic disease (b = -0.46 [-0.70 to -0.21], p < 0.001). Obesity was a weak and unreliable predictor, and we did not detect any influence of site of pain. The surgeons' habitual practice (proportion of UKRs over all knee replacements performed in a typical year) was the second strongest predictor after ACL (b = 1.26 [0.54-1.99], p = 0.001).

Conclusions

ACL integrity was the most important determinant of surgeons' preferences between TKR and UKR. Their habitual practice was also a strong predictor, outweighing most clinical factors in the vignettes.

Impact of Age in Single-Level Versus Multilevel Airway Compromise: A Multi-Institutional Review

OBJECTIVE

Examine the association between age and treatment outcomes in conditions causing single- versus multilevel airway restriction.

STUDY DESIGN

Multi-institutional retrospective cohort study.

SETTING

Tertiary laryngology centers.

METHODS

Participants included younger (18-64 years) and geriatric (≥65 years) adults with posterior glottic stenosis (PGS), multilevel airway stenosis (MLAS), and bilateral vocal fold paralysis (BVFP). Subgroup demographics, comorbidities, type, and etiology of airway compromise were described. Associations between age and primary outcome variables (i.e., tracheostomy and decannulation rates, number of surgeries performed, time between surgeries, and change in quality-of-life patient-reported outcome measures [PROMs]) were evaluated. Statistical analyses included independent t tests, χ2, Fisher's exact, or Mann-Whitney tests.

RESULTS

In 158 patients [96 younger (30 PGS, 29 MLAS, 37 BVFP) and 62 geriatric (24 PGS, 9 MLAS, 29 BVFP)], age differences were not significant for gender (P = .990), tracheostomy placement (70% vs 66%, P = .629), or decannulation success (40% vs 24%, P = .091) in younger versus geriatric groups, respectively. In younger patients, MLAS was more common (30.2% vs 14.5%, P = .024), and BVFP patients were more likely to decannulate (50% vs 12%, P = .017). Geriatric patients were more likely to have a history of prior radiation (26% vs 10%, P = .016), stenosis due to malignancy (23% vs 9%, P = .022), and fewer overall surgeries (median 1 vs 3, P = .003). Median PROMs were comparable between age subgroups (P > .05).

CONCLUSION

Younger adults underwent more surgeries, but overall comorbidities, tracheostomy decannulation rates, and PROMs were comparable between groups. Age does not negatively impact treatment outcomes and should not be a deterrent in treatment decision-making.

Barriers faced by surgeons in identifying and managing malnutrition in emergency general surgery: A qualitative study

AIM

Many patients undergoing emergency surgery are malnourished. Identifying malnutrition is a prerequisite to offering targeted nutritional support. Guidelines exist but little is known regarding exactly how surgeons identify malnutrition, or the barriers that influence surgeons' clinical decision-making. The aim of this work was to explore how consultant surgeons identify malnutrition in emergency general surgery (EGS) patients and the barriers to nutritional assessment and intervention.

METHOD

Consultant surgeons with emergency surgery duties were invited to participate. Semi-structured interviews were conducted online, audiovisually recorded and transcribed. An inductive approach was used for data analysis using the framework method. Coding and analysis were performed by two independent researchers using NVivo software. Themes were developed and reviewed with the supervising team. Interviews continued until data saturation was reached. Ethical approval was gained prior to interviews.

RESULTS

Eighteen interviews were conducted across three hospital settings. Identification of malnutrition consisted of three themes: 'The surgeon' (knowledge, experience, planning ahead); 'The patient' (selection, composition, clinical progress, operative considerations); and 'The institution' (collaboration, extended surgical team). Three themes encompassed barriers experienced: 'The surgeon' (understanding, culture, ownership, time constraints); 'The institution' (provision, staffing, conflict, hospital setting); and 'The wider context' (research, external factors). These influenced clinical decision-making, which had two themes: 'To join or not to join' (risk taking, site of anastomosis) and 'Nutritional support' (timing, referral pathways).

CONCLUSIONS

The identification and management of malnutrition in EGS is fraught with barriers, impacting operative and clinical decision-making. Improvements in surgeon education, culture, collaborative working and resources are needed.

Factors Associated With Surgical Management in Gallbladder Cancer-A Surveillance, Epidemiology, and End Results Medicare-Based Study

INTRODUCTION

Gallbladder cancer (GBC) incidence is rising, yet prognosis remains poor. Oncological resection of stage T1b or higher improves survival, yet many patients do not receive appropriate resection. This study aims to evaluate factors that may attribute to this discrepancy using the Surveillance, Epidemiology, and End Results-Medicare (SEER-Medicare) database.

MATERIALS AND METHODS

SEER Medicare (2008-2015) patients with GBC stage T1b or higher were classified as receiving cholecystectomy alone (CCY) or cholecystectomy and liver/biliary resection (oncologic resection). Outcomes and overall survival were compared, before and after propensity score matching on baseline characteristics, using Chi-square and Wilcoxon rank-sum tests for categorical and continuous variables, respectively.

RESULTS

We identified 1129 patients of which 830 underwent CCY (58.3% early stage/41.7% late stage) while 299 had complete resection (54.2% early stage/45.8% late stage). CCY patients were more often female (73.4% versus 65.6%; P = 0.0104), ≥80 y old (48.2% versus 22.4%; P < 0.0001), frail (44.5% versus 27.1%; P < 0.0001), treated by general surgeons (98.1% versus 84.9%; P < 0.0001) versus surgical oncologists, not undergoing chemotherapy (72.3% versus 54.5%; P < 0.0001), managed at nonacademic hospitals (51.2% versus 28.4%; P < 0.0001). After matching, oncologic resection demonstrated improved overall survival compared to CCY at 1-y (69.2% versus 47.2%; P < 0.0001), 3-y (42.8% versus 21.1%; P < 0.0001), and 5-y (37.5% versus 17.4%; P < 0.0001).

CONCLUSIONS

Most GBC patients may not be receiving appropriate oncological resection, especially patients who are female, older, frail, operated on by a general surgeon, not undergoing chemotherapy, or managed at nonacademic hospitals. Even when adjusting for patient factors, complete resection is associated with overall survival outcomes at multiple endpoints. Limiting sex, age, and frail status as factors and involving surgical oncologists or receiving management at academic centers may increase oncologic resection rates and thus improve survival for GBC patients.

AI Versus MD: Evaluating the surgical decision-making accuracy of ChatGPT-4

BACKGROUND

ChatGPT-4 is a large language model with possible applications to surgery education The aim of this study was to investigate the accuracy of ChatGPT-4's surgical decision-making compared with general surgery residents and attending surgeons.

METHODS

Five clinical scenarios were created from actual patient data based on common general surgery diagnoses. Scripts were developed to sequentially provide clinical information and ask decision-making questions. Responses to the prompts were scored based on a standardized rubric for a total of 50 points. Each clinical scenario was run through Chat GPT-4 and sent electronically to all general surgery residents and attendings at a single institution. Scores were compared using Wilcoxon rank sum tests.

RESULTS

On average, ChatGPT-4 scored 39.6 points (79.2%, standard deviation ± 0.89 points). A total of five junior residents, 12 senior residents, and five attendings completed the clinical scenarios (resident response rate = 15.9%; attending response rate = 13.8%). On average, the junior residents scored a total of 33.4 (66.8%, standard deviation ± 3.29), senior residents 38.0 (76.0%, standard deviation ± 4.75), and attendings 38.8 (77.6%, standard deviation ± 5.45). ChatGPT-4 scored significantly better than junior residents (P = .009) but was not significantly different from senior residents or attendings. ChatGPT-4 was significantly better than junior residents at identifying the correct operation to perform (P = .0182) and recommending additional workup for postoperative complications (P = .012).

CONCLUSION

ChatGPT-4 performed superior to junior residents and equivalent to senior residents and attendings when faced with surgical patient scenarios. Large language models, such as ChatGPT, may have the potential to be an educational resource for junior residents to develop surgical decision-making skills.

Comparative Study of Endoscopic Transcanal Tympanoplasty and Tympanoplasty by Conventional Postaural Approach in a Tertiary Care Hospital in Central India

Background Chronic otitis media (COM) often necessitates tympanoplasty to repair the tympanic membrane. While conventional postaural tympanoplasty (PA) is well-established, endoscopic transcanal tympanoplasty (ET) is gaining traction for its minimally invasive benefits. This study aims to compare these two surgical techniques regarding their anatomical and functional outcomes and assess the role of platelet-rich plasma (PRP) in improving these outcomes. Material and methods This prospective comparative study was conducted at Acharya Vinoba Bhave Rural Hospital, involving 60 patients with COM. Participants were randomly assigned to receive either ET or PA, with each group further subdivided based on PRP use. Preoperative evaluations included auditory function tests and diagnostic endoscopy. Postoperative assessments were performed at seven days, one month, and three months to evaluate graft acceptance and hearing improvement using pure tone audiometry (PTA). Statistical analyses included the chi-square test, t-test, ANOVA, and paired t-test. Results The study included patients with a mean age of 38.1 years, predominantly female (71.67%). ET demonstrated superior anatomical outcomes compared to PA, with higher graft acceptance rates and better hearing improvements. The average hearing gain was 10.4 dB in the ET group versus 8.1 dB in the PA group. PRP uses enhanced graft acceptance and hearing restoration across both surgical approaches, contributing to better overall outcomes. Conclusion ET offers significant advantages over conventional postaural tympanoplasty in terms of anatomical and functional results. PRP further improves surgical outcomes, making ET a preferable option for tympanoplasty in COM patients. These findings support the broader adoption of ET and PRP to enhance patient outcomes in tympanoplasty procedures.

Evaluation of Maxillary Sinus Septa Using Cone Beam Computed Tomography (CBCT): A Retrospective Study

BACKGROUND

Maxillary sinus septa, which are bony structures dividing the sinus cavity, can pose challenges during sinus lift or implant surgeries by potentially causing perforation of the Schneiderian membrane. This study aimed to estimate the prevalence, height, location, orientation, and risk of perforation of the maxillary sinus septa using cone beam computed tomography (CBCT).

MATERIALS AND METHODS

This retrospective, cross-sectional study utilized CBCT (NewTom CBCT machine, of which the scan parameters were 90 KvP, 8 mAs, and 14 s exposure with a field of view (FOV) of 8×8 cm and a 0.2 mm3 voxel size) images of 300 maxillary sinuses from patients aged >18 years, obtained from Swami Devi Dyal Hospital and Dental College in Panchkula, India. Scans were analyzed for the presence, height, location, orientation, and risk of septal perforation. The data were categorized based on age, sex, and dentition status. Statistical analyses were performed to assess the prevalence, configuration, and risk factors.

RESULTS

The prevalence of maxillary sinus septa was 21.33%, with the majority showing a single septum (90.63%). Septa were predominantly found in the middle region (48.44%), with bucco-palatal orientation (93.75%) being more common than anteroposterior. The mean septa height was 6.16 mm. The perforation was classified as moderate (48.4%), low (46.8%), or high (4.6%). Class III septa were associated with the highest risk of perforation.

CONCLUSION

This study highlights a significant prevalence of maxillary sinus septa with variations in height, orientation, and location. The risk of perforation varies with the septa configuration and orientation. CBCT is essential for identifying these anatomical features to minimize surgical complications and to guide preoperative planning.

Factors influencing the decision-making process in breast reconstruction from the perspective of reconstructive surgeons: A qualitative study involving Korean plastic surgeons

BACKGROUND

Little research has been conducted on factors influencing the decision-making process for immediate breast reconstruction (IBR) options from the perspective of reconstructive surgeons, despite its significant impact on doctor-patient communication and shared decision-making. This study aims to explore the multiple factors and the mechanisms by which they interact using a qualitative methodology. We also address potential barriers to shared decision-making in IBR.

METHODS

Semistructured interviews were conducted with a purposive sample of reconstructive surgeons. Thematic analysis was used to identify key influences on IBR decision-making process from the perspective of reconstructive surgeons.

RESULTS

Four major themes were identified: 1. Patient clinical scenarios; 2. Nonclinical practice environments; 3. Reconstructive surgeon preferences; and 4. Patient consultation. Reconstructive surgeons demonstrated diverse approaches to patient clinical scenarios. High-volume centers were significantly influenced by nonclinical factors such as scheduling and operating room allocation systems. Reconstructive surgeons often had strong personal preferences for specific IBR options, shaped by their expertise, experience, and clinical environment. Based on the preliminary decision, surgeons provided information with varying degrees of neutrality. Patients varied in their knowledge and participation, resulting in variation in the final decision authority among surgeons.

CONCLUSIONS

This study highlights the need to address nonclinical environmental constraints to improve shared decision-making process in IBR. Surgeons should recognize power imbalances in the doctor-patient relationship and be aware of their biases.

Incidence and predictors of postoperative complications in Sub-Saharan Africa: a systematic review and meta-analysis

Background

Postoperative complications remain a significant challenge, especially in settings where healthcare access and infrastructure disparities exacerbate. This systematic review and meta-analysis aimed to determine the pooled incidence and risk factors of postoperative complications among patients undergoing essential surgery in Sub-Saharan Africa (SSA).

Method

PubMed/MEDLINE, EMBASE, CINAHL, Web of Science, and Google Scholar were searched from January 2010 to November 2022 for completed studies reporting the incidence and risk factors associated with postoperative complications among patients undergoing essential surgery in SSA. Severity of postoperative complications was ranked based on the Clavien-Dindo classification system, while risk factors were classified into three groups based on the Donabedian structure-process-outcome quality evaluation framework. Studies quality was appraised using the JBI Meta-Analysis of Statistics Assessment and Review Instrument (JBI-MAStARI), and data were analyzed using Comprehensive Meta-Analysis (CMA) software. The study protocol adhered to the PRISMA guidelines and was registered in PROSPERO (CRD42023414342).

Results

The meta-analysis included 19 studies (10 cohort and 9 cross-sectional) comprising a total of 24,136 patients. The pooled incidence of postoperative complications in SSA was 20.2% (95% CI: 18.7%-21.8%), with a substantial heterogeneity of incidence observed. The incidence varied from 14.6% to 27.5% based on the Clavien-Dindo classification. The random-effects model indicated significant heterogeneity among the studies (Q = 54.202, I = 66.791%, p < 0.001). Contributing factors to postoperative complications were: structure-related factors, which included the availability and accessibility of resources, as well as the quality of both the surgical facility and the hospital.; process-related factors, which encompassed surgical skills, adherence to protocols, evidence-based practices, and the quality of postoperative care; and patient outcome-related factors such as age, comorbidities, alcohol use, and overall patient health status.

Conclusion

The meta-analysis reveals a high frequency of postoperative complications in SSA, with noticeable discrepancies among the studies. The analysis highlights a range of factors, encompassing structural, procedural, and patient outcome-related aspects, that contribute to these complications. The findings underscore the necessity for targeted interventions aimed at reducing complications and improving the overall quality of surgical care in the region.

Review and analysis of history and utilization of pneumatic retinopexy after pneumatic retinopexy versus vitrectomy for the management of primary rhegmatogenous retinal detachment outcomes randomized trial (PIVOT)

PURPOSE OF REVIEW

We describe the history and series results of pneumatic retinopexy (PnR)and provide an analysis of PnR utilization after publication of results of pneumatic retinopexy versus vitrectomy for the management of primary rhegmatogenous retinal detachment outcomes randomized trial (PIVOT).

RECENT FINDINGS

No significant trends were found for average number of services ( P  = 0.153) of PnR after the publication of PIVOT results.

SUMMARY

PnR is a rhegmatogenous retinal detachment (RRD) repair technique that was first described in the early 1900 s and has evolved over time to become a modern-day, minimally invasive, underutilized treatment option. Other repair techniques for RRD include scleral buckling and pars plana vitrectomy (PPV), which has been compared to the use of PnR in PIVOT. Results of PIVOT concluded that PnR offered superior visual acuity and noninferiority. PnR is underutilized in the United States even after publication of results of PIVOT deemed it a noninferior treatment. Lack of a significant increase in national utilization of PnR could be associated with multifactorial clinician, systems, and financial reasons in the real-world setting.

Association of Radiographic Soft Tissue Thickness With Revision Total Ankle Arthroplasty Following Primary Total Ankle Arthroplasty: A Minimum of 5-year Follow-up

Background

The incidence of primary total ankle arthroplasty (TAA) is rising, with a corresponding increase in revision surgeries. Despite this, research on risk factors for revision TAA following primary TAA remains limited. Radiographic soft tissue thickness has been explored as a potential predictor for outcomes in hip, knee, and shoulder arthroplasty, but its role in TAA has not been assessed. This study aimed to assess the predictive value of radiographic soft tissue thickness for identifying patients at risk of requiring revision surgery following primary TAA.

Methods

A retrospective study was conducted on 323 patients who underwent primary TAA between 2003 and 2019. Radiographic measurements of soft tissue thickness were obtained from preoperative radiographs. Two novel radiographic measures of soft tissue thickness were developed and assessed (tibial tissue thickness and talus tissue thickness). Clinical variables including age, gender, body mass index (BMI), American Society of Anesthesiologists (ASA) classification, diabetes, smoking status, primary diagnosis, and implant type were recorded. Logistic regression analysis was used to assess the predictive value of soft tissue thickness and BMI for revision TAA.

Results

The rate of revision surgery was 4.3% (14 of 323 patients). Patients requiring revision had significantly greater tibial tissue (3.54 vs 2.48 cm; P = .02) and talus tissue (2.79 vs 2.42 cm; P = .02) thickness compared with those not requiring revision. Both the tibial tissue thickness (odds ratio 1.16 [1.12-1.20]; P < .01) and the talus tissue thickness (odds ratio: 1.10 [1.05-1.15]; P < .01) measurements were significant predictors of revision TAA in multivariable logistic regression models. However, BMI was not a significant predictor of revision TAA. The two metrics demonstrated excellent interrater reliability.

Conclusion

Greater soft tissue thickness was a better predictor of revision TAA compared with BMI. These findings suggest that radiographic soft tissue thickness may be a valuable tool for assessing the risk of the need for revision TAA following primary TAA. Further research is needed to validate and explore the potential impact on clinical practice.

Variations in surgical practice and short-term outcomes for degenerative lumbar scoliosis and spondylolisthesis: do surgeon training and experience matter?

For diverse procedures, sizable geographic variation exists in rates and outcomes of surgery, including for degenerative lumbar spine conditions. Little is known about how surgeon training and experience are associated with surgeon-level variations in spine surgery practice and short-term outcomes. This retrospective observational analysis characterized variations in surgical operations for degenerative lumbar scoliosis or spondylolisthesis, two common age-related conditions. The study setting was two large spine surgery centers in one region during 2017-19. Using data (International Classification of Diseases-10th edition and current procedural terminology codes) extracted from electronic health record systems, we characterized surgeon-level variations in practice (use of instrumented fusion - a more extensive procedure that involves device-related risks) and short-term postoperative outcomes (major in-hospital complications and readmissions). Next, we tested for associations between surgeon training (specialty and spine fellowship) and experience (career stage and operative volume) and use of instrumented fusion as well as outcomes. Eighty-nine surgeons performed 2481 eligible operations. For the study diagnoses, spine surgeons exhibited substantial variation in operative volume, use of instrumented fusion, and postoperative outcomes. Among surgeons above the median operative volume, use of instrumented fusion ranged from 0% to >90% for scoliosis and 9% to 100% for spondylolisthesis, while rates of major in-hospital complications ranged from 0% to 25% for scoliosis and from 0% to 14% for spondylolisthesis. For scoliosis, orthopedic surgeons were more likely than neurosurgeons to perform instrumented fusion for scoliosis [49% vs. 33%, odds ratio (OR) = 2.3, 95% confidence interval (95% CI) 1.3-4.2, P-value = .006] as were fellowship-trained surgeons (49% vs. 25%, OR = 3.0, 95% CI 1.6-5.8; P = .001). Fellowship-trained surgeons had lower readmission rates. Surgeons with higher operative volumes used instrumented fusion more often (OR = 1.1, 95% CI 1.0-1.2, P < .05 for both diagnoses) and had lower rates of major in-hospital complications (OR = 0.91, 95% CI 0.85-0.97; P = .006). Surgical practice can vary greatly for degenerative spine conditions, even within the same region and among colleagues at the same institution. Surgical specialty and subspecialty, in addition to recent operative volume, can be linked to variations in spine surgeons' practice patterns and outcomes. These findings reinforce the notion that residency and fellowship training may contribute to variation and present important opportunities to optimize surgical practice over the course of surgeons' careers. Future efforts to reduce unexplained variation in surgical practice could test interventions focused on graduate medical education. Graphical Abstract.

Substantial Variation in Decision Making to Perform Subacromial Decompression Surgery for Subacromial Pain Syndrome Between Orthopaedic Shoulder Surgeons for Identical Clinical Scenarios: A Case-Vignette Study

Purpose

To provide further insight into the variation in decision making to perform subacromial decompression (SAD) surgery in patients with subacromial pain syndrome (SAPS) and its influencing factors.

Methods

Between November 2021 and February 2022, we invited 202 Dutch Shoulder and Elbow Society members to participate in a cross-sectional Web-based survey including 4 clinical scenarios of SAPS patients. Scenarios varied in patient characteristics, clinical presentation, and other contextual factors. For each scenario, respondents were asked (1) to indicate whether they would perform SAD surgery, (2) to indicate the probability of benefit of SAD surgery (i.e., pain reduction), (3) to indicate the probability of harm (i.e., complications), and (4) to rank the 5 most important factors influencing their treatment decision.

Results

A total of 78 respondents (39%) participated. The percentage of respondents who would perform SAD surgery ranged from 4% to 25% among scenarios. The median probability of perceived benefit ranged between 70% and 79% across scenarios for respondents indicating to perform surgery compared with 15% to 29% for those indicating not to perform surgery. The difference in the median probability of perceived harm ranged from 3% to 9% for those indicating to perform surgery compared with 8% to 13% for those indicating not to perform surgery. Surgeons who would perform surgery mainly reported patient-related factors (e.g., complaint duration and response to physical therapy) as the most important factors to perform SAD surgery, whereas surgeons who would not perform surgery mainly reported guideline-related factors.

Conclusions

Overall, Dutch orthopaedic shoulder surgeons are reluctant to perform SAD surgery in SAPS patients. There is substantial variation among orthopaedic surgeons regarding decisions to perform SAD surgery for SAPS even when evaluating identical scenarios, where particularly the perceived benefit of surgery differed between those who would perform surgery and those who would not. Surgeons who would not perform SAD surgery mainly referred to guideline-related factors as influential factors for their decision, whereas those who would perform SAD surgery considered patient-related factors more important.

Clinical Relevance

There is substantial variation in decision making to perform SAD surgery for SAPS between individual orthopaedic surgeons for identical case scenarios.

Surgeon Preference for Prophylactic Contralateral Fixation in Slipped Capital Femoral Epiphysis (SCFE) Patients: A Nationwide POSNA Survey Study

BACKGROUND

It is estimated that 11% to 60% of unilateral slipped capital femoral epiphysis (SCFE) patients will develop contralateral pathology, usually within 18 months after the first event. Despite this, prophylactic fixation remains controversial, and there is significant variability in surgeon preferences. Thus, this study aimed to determine which factors predict surgeon preferences for prophylactic contralateral pinning in SCFE patients.

METHODS

We designed a survey for pediatric orthopedic surgeons to collect data on (1) surgeon and hospital characteristics, (2) individual preference for contralateral SCFE pinning in three disparate hypothetical scenarios, and (3) personal risk-aversion traits. The questionnaire was distributed across the United States by the POSNA Evidence-Based Orthopaedics Committee. All POSNA members were eligible to respond. We performed analyses to evaluate the role of patient risk factors in hypothetical surgical decision-making and to determine if surgical training, hospital characteristics, and geographic region influenced prophylactic pinning in a surgeon's real-life practice.

RESULTS

A total of 126 POSNA members responded to the survey. In the last year, a median of 6.5 SCFE patients was seen per surgeon (1243 patients total). A median of 10% of those patients underwent prophylactic contralateral fixation. In multiple analyses, surgeons were influenced by body mass index, open triradiate cartilage, patient race, various endocrine abnormalities, and specific radiographic measurements when deciding to fix the contralateral side prophylactically. Moreover, in multivariate regression, more years in practice and a hospital size of 500+ beds predicted fewer prophylactic fixation procedures (all P <0.05). Surgeons practicing in the South Atlantic, New England, and Mountain regions of the United States estimated the highest rate of contralateral pinning.

CONCLUSIONS

This study's findings suggest that multiple factors influence surgeons' decisions to prophylactically fix the contralateral side in SCFE patients. Surgical training, hospital characteristics, and geographical regions played a role in decision-making.

Evaluating consensus and uncertainty among treatment options for early-onset scoliosis: new generation and international perspectives

PURPOSE

It is currently unknown how treatment preferences differ between a senior group of U.S. spinal surgeons, a new generation of U.S. surgeons, and non-U.S. surgeons with regard to the treatment of early-onset scoliosis (EOS). The purpose of this study was to evaluate clinical consensus and uncertainty among treatment options for patients with EOS to understand how they compare between these three cohorts.

METHODS

11 senior pediatric spinal deformity surgeons in the U.S., 12 "junior" surgeons in the U.S., and 7 surgeons practicing in non-U.S. countries were invited to complete a survey of 315 idiopathic and neuromuscular EOS case scenarios. Treatment options included: conservative management, distraction-based methods, growth guidance/modulation, and arthrodesis. Consensus was defined as ≥ 70% agreement, and uncertainty was < 70%. Chi-squared and multiple regression analyses were performed to evaluate the associations between case characteristics and consensus for different treatments.

RESULTS

Although all 3 cohorts of surgeons chose conservative management most frequently, the non-U.S. cohort of surgeons chose distraction-based methods more often, particularly for neuromuscular cases. In both U.S. surgeon cohorts, there was consensus for conservative management in idiopathic patients aged 3 or younger regardless of other factors, whereas non-U.S. surgeons selected distraction-based methods for some of these patients.

CONCLUSION

Just as research studies are being conducted to find approaches to optimally manage the EOS population, future research efforts should focus on identifying the reasoning behind treatment preferences in different cohort of surgeons, as this will allow the interexchange of information which can ultimately improve EOS care.

International Society of University Colon and Rectal Surgeons survey of surgeons' preference on rectal cancer treatment

PURPOSE

Rectal cancer treatment has a wide range of possible approaches from radical extirpative surgery to nonoperative watchful waiting following chemoradiotherapy, with or without, additional chemotherapy. Our goal was to assess the personal opinion of active practicing surgeons on rectal cancer treatment if he/she was the patient.

METHODS

A panel of the International Society of University Colon and Rectal Surgeons (ISUCRS) selected 10 questions that were included in a questionnaire that included other items including demographics. The questionnaire was distributed electronically to ISUCRS fellows and other surgeons included in our database and remained open from April 16 to 28, 2020.

RESULTS

One hundred sixty-three specialists completed the survey. The majority of surgeons (n=65, 39.9%) chose the minimally invasive (laparoscopic) surgery for their personal treatment of rectal cancer. For low-lying rectal cancer T1 and T2, the treatment choice was standard chemoradiation+local excision (n=60, 36.8%) followed by local excision±chemoradiotherapy if needed (n=55, 33.7%). In regards to locally advanced low rectal cancer T3 or greater, the preference of the responders was for laparoscopic surgery (n=65, 39.9%). We found a statistically significant relationship between surgeons' age and their preference for minimally invasive techniques demonstrating an age-based bias on senior surgeons' inclination toward open approach.

CONCLUSION

Our survey reveals an age-based preference by surgeons for minimally invasive surgical techniques as well as organ-preserving techniques for personal treatment of treating rectal cancer. Only 1/4 of specialists do adhere to the international guidelines for treating early rectal cancer.

An assessment of the variation in the practice of lumbar discectomy and its role in axial back pain

Background

Lumbar discectomy is performed for symptomatic lumbar disc herniation and is one of the most widely performed spinal surgical procedures worldwide in a variety of ways. This survey aimed at providing an overview/perspective of different practice patterns and the impact of lumbar discectomy on axial back pain with or without sciatica.

Methods

An online survey was performed using the application "Google Forms." The link to the questionnaire was distributed to neurosurgeons through personal E-mail and social media platforms.

Results

We received 333 responses. The largest percentage of responses across five continents was from Asia (66.97%, n = 223). The mean age of the respondents was 40.08 ± 10.5 years. A total of 66 respondents (20%) had a spine practice of 7%-90%, and 28 respondents had a spine practice of 90%-100% (8.4%). The number of respondents who practiced microscopic discectomy using a tubular retractor (n = 143 respondents, 42.9%) was nearly equal to the number of respondents who practiced open discectomy (n = 142 respondents, 42.6%). An almost equal proportion of respondents believed discectomy does not help in relieving axial back pain. Only 20.4% (n = 68) of respondents recommend bed rest for a longer duration postoperatively.

Conclusions

Our survey revealed that only 22.2% of spine surgeons recommended discectomy in patients with radiological disc herniation with axial back pain alone and preferred a minimally invasive method of discectomy. Almost half of them believed discectomy to be ineffective for axial low back pain and only a few recommended prolonged bed rest postoperatively.

Interventions for sustainable surgery: a systematic review

OBJECTIVE

To systematically evaluate interventions designed to improve the sustainability of surgical practice with respect to their environmental and financial impact.

BACKGROUND

Surgery contributes significantly to emissions attributed to healthcare due to its high resource and energy use. Several interventions across the operative pathway have, therefore, been trialed to minimize this impact. Few comparisons of the environmental and financial effects of these interventions exist.

MATERIALS AND METHODS

A search of studies published up to 2nd February 2022 describing interventions to increase surgical sustainability was undertaken. Articles regarding the environmental impact of only anesthetic agents were excluded. Data regarding environmental and financial outcomes were extracted with a quality assessment completed dependent upon the study design.

RESULTS

In all, 1162 articles were retrieved, of which 21 studies met inclusion criteria. Twenty-five interventions were described, which were categorized into five domains: 'reduce and rationalize', 'reusable equipment and textiles', 'recycling and waste segregation', 'anesthetic alternatives', and 'other'. Eleven of the 21 studies examined reusable devices; those demonstrating a benefit reported 40-66% lower emissions than with single-use alternatives. In studies not showing a lower carbon footprint, the reduction in manufacturing emissions was offset by the high environmental impact of local fossil fuel-based energy required for sterilization. The per use monetary cost of reusable equipment was 47-83% of the single-use equivalent.

CONCLUSIONS

A narrow repertoire of interventions to improve the environmental sustainability of surgery has been trialed. The majority focuses on reusable equipment. Emissions and cost data are limited, with longitudinal impacts rarely investigated. Real-world appraisals will facilitate implementation, as will an understanding of how sustainability impacts surgical decision-making.

Clinicians' perceptions around discectomy surgery for lumbar disc herniation: a survey of orthopaedic and neuro-surgeons in Australia and New Zealand

INTRODUCTION

Understanding practice-based differences in treatment of lumbar disc herniations (LDHs) is vital for reducing unwarranted variation in the delivery of spine surgical health care. Identifying factors that influence surgeons' decision-making will offer useful insights for developing the most cost-effective and safest surgical strategy as well as developing surgeon education materials for common lumbar pathologies. This study was to capture any variation in techniques used by surgeons in Australia and New Zealand (ANZ) region, and perceived complications of different surgical procedures for primary and recurrent LDH (rLDH).

MATERIALS AND METHODS

Web-based survey study was emailed to orthopaedic and neurosurgeons who routinely performed spinal surgery in ANZ from Decmber 20, 2018 to February 20, 2020. The response data were analyzed to assess for differences based on geography, practice setting, speciality, practice experience, practice length, and operative volume.

RESULTS

Invitations were sent to 150 surgeons; 96 (64%) responded. Most surgeons reported microdiscectomy as their surgical technique of choice for primary LDH (73%) and the first rLDH (72%). For the second rLDH, the preferred choice for most surgeons was fusion surgery (82%). A surgeon's practice setting (academic/private/hybrid) was a statistically significant factor in what surgical procedure was chosen for the first rLDH (P = 0.014). When stratifying based on surgeon experience, there were statisfically significant differences based on the annual volume of spine surgeries performed (perceived reherniation rates following primary discectomy, P = 0.013; perceived reherniation rates following revision surgeries, P = 0.017; perceived intraoperative complications rates following revision surgeries, P = 0.016) and based on the annual volume of lumbar discectomies performed (perceived reherniation rates following revision surgeries, P = 0.022; perceived intraoperative complications rates following revision surgeries, P = 0.036; perceived durotomy rates following primary discectomy, P = 0.023).

CONCLUSIONS

Surgeons' annual practice volume and practice setting have significant influences in the selection of surgical procedures and the perception of surgical complications when treating LDHs.

Protective ileostomy creation after anterior resection of the rectum: Shared decision-making or still subjective?

AIM

The choice of whether to perform protective ileostomy (PI) after anterior resection (AR) is mainly guided by risk factors (RFs) responsible for the development of anastomotic leakage (AL). However, clear guidelines about PI creation are still lacking in the literature and this is often decided according to the surgeon's preferences, experiences or feelings. This qualitative study aims to investigate, by an open-ended question survey, the individual surgeon's decision-making process regarding PI creation after elective AR.

METHOD

Fifty four colorectal surgeons took part in an electronic survey to answer the questions and describe what usually led their decision to perform PI. A content analysis was used to code the answers. To classify answers, five dichotomous categories (In favour/Against PI, Listed/Unlisted RFs, Typical/Atypical, Emotions/Non-emotions, Personal experience/No personal experience) have been developed.

RESULTS

Overall, 76% of surgeons were in favour of PI creation and 88% considered listed RFs in the question of whether to perform PI. Atypical answers were reported in 10% of cases. Emotions and personal experience influenced surgeons' decision-making process in 22% and 49% of cases, respectively. The most frequently considered RFs were the distance of the anastomosis from the anal verge (96%), neoadjuvant chemoradiotherapy (88%), a positive intraoperative leak test (65%), blood loss (37%) and immunosuppression therapy (35%).

CONCLUSION

The indications to perform PI following rectal cancer surgery lack standardization and evidence-based guidelines are required to inform practice. Until then, expert opinion can be helpful to assist the decision-making process in patients who have undergone AR for adenocarcinoma.

Biomechanical effects of cross-pin's diameter in reconstruction of anterior cruciate ligament - A specific case study via finite element analysis

For anterior cruciate ligament reconstruction (ACL-R), one of the crucial aspects of treatment is the fixator selection that could provide initial graft fixation post-operatively. Literature on biomechanical stabilities of different sizes of fixators as femoral graft fixation is limited. Therefore, this study aims to analyse the influence of different diameters of cross-pins on the stability of graft fixations after ACL-R via finite element analysis (FEA). In the methodology, three-dimensional (3D) models of three different diameters of cross-pins were developed, of which anterior tibial loads (ATL) were applied onto the tibia. From the findings, the cross-pin with a smaller diameter (4 mm) provided optimum stability than larger diameter cross-pins, whereby it demonstrated acceptable stresses at the fixators (both cross-pin and interference screw) with a different percentage of 28%, while the stresses at the corresponding bones were favourable for osseointegration to occur. Besides, the strains of the knee joint with 4 mm diameter cross-pin were also superior in providing a good biomechanical environment for bone healing, while the recorded strain values at fixators were comparable with a larger diameter of cross-pins without being inferior in terms of deformation. To conclude, the cross-pin with 4 mm diameter depicted the best biomechanical aspects in graft fixation for ACL-R since it allows better assistance for the osseointegration process and can minimise the possibility of the breakage and migration of fixators. This study is not only useful for medical surgeons to justify their choices of pin diameter to treat patients, but also for researchers to conduct future studies.

Minimally Invasive Sacroiliac Joint Fusion vs Conservative Management in Patients With Sacroiliac Joint Dysfunction: A Systematic Review and Meta-Analysis

BACKGROUND

The sacroiliac joint (SIJ) is affected in 14% to 22% in individuals presenting with chronic low back or buttock pain. This percentage is even higher in patients who underwent lumbar fusion surgery: 32% to 42%. Currently, there is no standard treatment or surgical indication for SIJ dysfunction. When patients do not respond well to nonsurgical treatment, minimally invasive sacroiliac joint fusion (MISJF) seems to be a reasonable option. This systematic review and meta-analysis evaluates the current literature on the effectiveness of MISJF compared to conservative management in patients with SIJ dysfunction.

METHODS

A systematic search of health-care databases was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Inclusion criteria were randomized controlled trials (RCTs) or prospective and retrospective comparative cohort studies that compared MISJF with conservative management. Primary outcome measures were pain, disability, and patient satisfaction measured by patient-reported outcome measures. Secondary outcomes were adverse events (AEs), serious AEs, financial benefits, and costs.

RESULTS

Two RCTs and one retrospective cohort study were included comparing MISJF and conservative management with regard to pain and disability outcome, encompassing 388 patients (207 conservative and 181 surgical). In a pooled mean difference analysis, MISJF demonstrated greater reduction in visual analog scale-pain score compared to conservative management: -37.03 points (95%CI [-43.91, -30.15], P < 0.001). Moreover, MISJF was associated with a greater reduction in Oswestry Disability Index outcome: -21.14 points (95% CI [-24.93, -17.35], P < 0.001). AEs were low among the study groups and comparable across the included studies. One cost-effectiveness analysis was also included and reported that MISJF is more cost-effective than conservative management.001). AEs were low among the study groups and comparable across the included studies. One cost-effectiveness analysis was also included and reported that MISJF is more cost-effective than conservative management.

CONCLUSIONS

This systematic review and meta-analysis suggest that MISJF, using cannulated triangular, titanium implants, is more effective and cost-effective than conservative management in reducing pain and disability in patients with SIJ dysfunction. Further well-powered, independent research is needed to improve the overall evidence.

Collaborative Review: Factors Influencing Treatment Decisions for Patients with a Localized Solid Renal Mass

CONTEXT

With the addition of active surveillance and thermal ablation (TA) to the urologist's established repertoire of partial (PN) and radical nephrectomy (RN) as first-line management options for localized renal cell carcinoma (RCC), appropriate treatment decision-making has become increasingly nuanced.

OBJECTIVE

To critically review the treatment options for localized, nonrecurrent RCC; to highlight the patient, renal function, tumor, and provider factors that influence treatment decisions; and to provide a framework to conceptualize that decision-making process.

EVIDENCE ACQUISITION

A collaborative critical review of the medical literature was conducted.

EVIDENCE SYNTHESIS

We identify three key decision points when managing localized RCC: (1) decision for surveillance versus treatment, (2) decision regarding treatment modality (TA, PN, or RN), and (3) decision on surgical approach (open vs minimally invasive). In evaluating factors that influence these treatment decisions, we elaborate on patient, renal function, tumor, and provider factors that either directly or indirectly impact each decision point. As current nomograms, based on preselected patient datasets, perform poorly in prospective settings, these tools should be used with caution. Patient decision aids are an underutilized tool in decision-making.

CONCLUSIONS

Localized RCC requires highly nuanced treatment decision-making, balancing patient- and tumor-specific clinical variables against indirect structural influences to provide optimal patient care.

PATIENT SUMMARY

With expanding treatment options for localized kidney cancer, treatment decision is highly nuanced and requires shared decision-making. Patient decision aids may be helpful in the treatment discussion.

The laparoscopy in emergency general surgery (LEGS) study: a questionnaire survey of UK practice

INTRODUCTION

Recent consensus guidelines suggest that the laparoscopic approach may be a useful, safe and feasible approach in emergency general surgery. Despite this, the UK National Emergency Laparotomy Audit (NELA) suggests the rate of laparoscopy is low (9% fully laparoscopic) and slow to increase over time. A European survey found uptake to be variable. This UK survey was therefore undertaken to establish current UK practice and to determine factors affecting implementation.

MATERIALS AND METHODS

A questionnaire survey of currently practising UK consultant general surgeons was carried out by the North West Surgical Research Collaborative, using a secure web-based database maintained by the North West Surgical Trials Centre.

RESULTS

A total of 151 completed questionnaires were returned from 22 UK centres; 18% of respondents were unaware that laparoscopic cases should be reported to NELA. Appendicectomy (97%) and cholecystectomy (87%) were routinely performed laparoscopically. Laparoscopy was infrequently used in perforation, ischaemia or obstructed hernias. There appears to be equipoise regarding laparoscopic compared with open surgery in small-bowel obstruction among all subspecialty emergency general surgeons, in perforated peptic ulcer among upper gastrointestinal surgeons and in Hinchey III diverticulitis among colorectal surgeons.

CONCLUSION

Uptake of laparoscopy in UK emergency general surgery is influenced by surgeon preference, subspecialty, patient and operative factors. Further research into outcomes may help to identify areas of greatest potential benefit. The rate of laparoscopy reported by NELA may be an underestimate due to the 18% of surgeons unaware that laparoscopic cases should be reported, which may affect the validity of analyses performed from this dataset.

Quality Improvement: Arterial Grafting Redux, 2010:2019

BACKGROUND

The evidence base favoring utilization of multiple arterial conduits in coronary artery bypass grafting has strengthened in recent years. Nevertheless, utilization of arterial conduits in the US lags behind that of many European peers. We describe a statewide collaborative based approach to improving utilization.

METHODS

Four metrics of arterial revascularization were devised. These were displayed and discussed at quarterly statewide quality collaborative meetings from January 2016 onwards, integrated with an educational program regarding attendant benefits. We undertook retrospective review of isolated coronary artery bypass grafting statewide from 2012-2019 to assess impact.

RESULTS

A total of 38,523 cases met inclusion/exclusion criteria. Statewide incidence of multiple arterial grafting increased from 7.4% at baseline to 21.7% in 2019 (P < .001), implementation across hospitals varied widely, ranging from 67.6% to 0.0%. Utilization of total arterial revascularization increased 1.9% to 4.4% (P < .001) between time frames. Utilization of both radial artery and bilateral internal thoracic artery conduit increased significantly from 5.3% to 13.2% (P < .001) and 2.1% to 8.5% (P < .001), respectively; radial artery utilization was significantly higher than bilateral internal thoracic artery for each year (P < .001 for all comparisons).

CONCLUSIONS

Our statewide quality improvement initiative improved rates of utilization of multiple arterial grafting by all metrics. Barriers to current utilization were identified to guide future quality improvement efforts. This reproducible approach is readily transferable to improve quality of care in other domains and geographical areas.

BIOMECHANICAL EFFECTS OF DIFFERENT LENGTHS OF CROSS-PINS IN ANTERIOR CRUCIATE LIGAMENT RECONSTRUCTION: A FINITE ELEMENT ANALYSIS

Complication rates of anterior cruciate ligament reconstruction (ACL-R) were reported to be around 15%. Although it is a very common arthroscopic surgery with good outcomes, breakage and migration of fixators are still possible to occur due to stability issue. One of the factors that affects the mechanical stability of fixators is its length. Therefore, the aim of this paper is to analyze the biomechanical effects of different lengths of fixators (cross-pin technique) towards the stabilities of the knee joint after ACL-R. Finite element analyses of knee joint with DST grafts and fixators were carried out. Mimics and 3-Matic were used in the development of knee joint models, while the grafts and fixators were designed by using SolidWorks software. All models were remeshed in the 3-Matic and numerical analysis was performed via MSC.Marc Mentat software. A 100 N anterior tibial load was applied onto the tibia to simulate the anterior drawer test after the surgery and proximal femur was fixed at all degrees of freedom. Based on the findings, cross-pin with 40[Formula: see text]mm in length provided the most favorable option for better treatment of ACL-R, where it could promote osseointegration and preventing fracture.

The rendezvous technique for the treatment of ipsilateral femoral neck and shaft fractures: A case series

Concomitant ipsilateral femoral neck and shaft fractures are uncommon high-energy injuries characteristically occurring in young adults. Between 75 and 100% of these injuries occur in association with polytrauma to other organ systems. Associated femoral neck fractures are typically undisplaced, occurring in 2–9% of all femoral shaft fractures. These injuries present both technical and infrastructural challenges particularly in a low resource environment. Several methods of treatment have been used to successfully treat these fractures but there exists no consensus about the optimal management strategy. The “rendezvous” technique using dual implants in an overlapping fashion has been proposed as one method to treat these fractures. We present three cases of ipsilateral hip and femoral shaft fractures which were satisfactorily treated using this technique. The “rendezvous” technique is a simple method, with a good clinical outcome and a low complication rate that can be used to treat ipsilateral femoral neck and shaft fractures.

Buruli ulcer treatment: Rate of surgical intervention differs highly between treatment centers in West Africa

Background

Antibiotic treatment proved itself as the mainstay of treatment for Buruli ulcer disease. This neglected tropical disease is caused by Mycobacterium ulcerans. Surgery persists as an adjunct therapy intended to reduce the mycobacterial load. In an earlier clinical trial, patients benefited from delaying the decision to operate. Nevertheless, the rate of surgical interventions differs highly per clinic.

Methods

A retrospective study was conducted in six different Buruli ulcer (BU) treatment centers in Benin and Ghana. BU patients clinically diagnosed between January 2012 and December 2016 were included and surgical interventions during the follow-up period, at least one year after diagnosis, were recorded. Logistic regression analysis was carried out to estimate the effect of the treatment center on the decision to perform surgery, while controlling for interaction and confounders.

Results

A total of 1193 patients, 612 from Benin and 581 from Ghana, were included. In Benin, lesions were most frequently (42%) categorized as the most severe lesions (WHO criteria, category III), whereas in Ghana lesions were most frequently (44%) categorized as small lesions (WHO criteria, category I). In total 344 (29%) patients received surgical intervention. The percentage of patients receiving surgical intervention varied between hospitals from 1.5% to 72%. Patients treated in one of the centers in Benin were much more likely to have surgery compared to the clinic in Ghana with the lowest rate of surgical intervention (RR = 46.7 CI 95% [17.5–124.8]). Even after adjusting for confounders (severity of disease, age, sex, limitation of movement at joint at time of diagnosis, ulcer and critical sites), rates of surgical interventions varied highly.

Conclusion

The decision to perform surgery to reduce the mycobacterial load in BU varies highly per clinic. Evidence based guidelines are needed to guide the role of surgery in the treatment of BU

Buruli ulcer is a necrotizing and disabling skin infection, caused by Mycobacterium ulcerans. The infection, a skin-related Neglected Tropical Diseases, affects mostly people living in limited resources settings. Since the introduction of rifampicin based combination antibiotic therapy as standard care, the role of surgery as adjunct therapy to kill M. ulcerans is less defined and understood. A randomized controlled trial showed benefit from delaying the decision to operate. Nevertheless, the rate of surgical interventions differs highly per clinic. We present the differences in rate of surgical interventions in six different Buruli ulcer treatment centers in Ghana and Benin. We demonstrate that these differences mainly depend on the opinion of the health care workers working in the treatment centers even after adjusting for disease severity.
