The Level of Knowledge of Nurses in Surgical Departments about the Occurrence of Stroke in Patients in the Postoperative Period

Introduction. Each year 80 000 Poles are suffering from stroke. The most common risk factors are hypertension, diabetes and complications, hyperlipidemia, obesity, atrial fibrillation. Lifestyle modification, such as diseases controlling, diet changing, exercises, stop smoking and limiting alcohol consumption are known as stroke prevention. Thrombectomy and thrombolytic therapy definitely increase long-term survival and prognosis. Aim. Objective of the work is assessment of surgical nurses knowledge level about postoperative stroke. Material and Methods. The research was conducted on a group of 55 randomly chosen surgical nurses. The diagnostic survey method with a proprietary questionnaire was used for the research. Results. Nurses knowledge was poor. Education and age affect to answers. Higher education qualification nurses have higher knowledge level relative to less educated nurses. Younger nurses have higher knowledge level than older nurses. Conclusions. Cardiosurgery and vascular surgery are charged as the most risk onset postoperative stroke. Knowledge of surgical nurses about risk factors, prevention, symptom, complications and procedures in case of stroke onset have particular meaning in postoperative caring.

Effectiveness of Immersive Virtual Reality on Orthopedic Surgical Skills and Knowledge Acquisition Among Senior Surgical Residents

Video learning prior to surgery is common practice for trainees and surgeons, and immersive virtual reality (IVR) simulators are of increasing interest for surgical training. The training effectiveness of IVR compared with video training in complex skill acquisition should be studied. To evaluate whether IVR improves learning effectiveness for surgical trainees and to validate a VR rating scale through correlation to real-world performance. This block randomized, intervention-controlled clinical trial included senior (ie, postgraduate year 4 and 5) orthopedic surgery residents from multiple institutions in Canada during a single training course. An intention-to-treat analysis was performed. Data were collected from January 30 to February 1, 2020. An IVR training platform providing a case-based module for reverse shoulder arthroplasty (RSA) for advanced rotator cuff tear arthropathy. Participants were permitted to repeat the module indefinitely. The primary outcome measure was a validated performance metric for both the intervention and control groups (Objective Structured Assessment of Technical Skills [OSATS]). Secondary measures included transfer of training (ToT), transfer effectiveness ratio (TER), and cost-effectiveness (CER) ratios of IVR training compared with control. Additional secondary measures included IVR performance metrics measured on a novel rating scale compared with real-world performance. A total of 18 senior surgical residents participated; 9 (50%) were randomized to the IVR group and 9 (50%) to the control group. Participant demographic characteristics were not different for age (mean [SD] age: IVR group, 31.1 [2.8] years; control group, 31.0 [2.7] years), gender (IVR group, 8 [89%] men; control group, 6 [67%] men), surgical experience (mean [SD] experience with RSA: IVR group, 3.3 [0.9]; control group, 3.2 [0.4]), or prior simulator use (had experience: IVR group 6 [67%]; control group, 4 [44%]). The IVR group completed training 387% faster considering a single repetition (mean [SD] time for IVR group: 4.1 [2.5] minutes; mean [SD] time for control group: 16.1 [2.6] minutes; difference, 12.0 minutes; 95% CI, 8.8-14.0 minutes; P < .001). The IVR group had significantly better mean (SD) OSATS scores than the control group (15.9 [2.5] vs 9.4 [3.2]; difference, 6.9; 95% CI, 3.3-9.7; P < .001). The IVR group also demonstrated higher mean (SD) verbal questioning scores (4.1 [1.0] vs 2.2 [1.7]; difference, 1.9; 95% CI, 0.1-3.3; P = .03). The IVR score (ie, Precision Score) had a strong correlation to real-world OSATS scores (r = 0.74) and final implant position (r = 0.73). The ToT was 59.4%, based on the OSATS score. The TER was 0.79, and the system was 34 times more cost-effective than control, based on CER. In this study, surgical training with IVR demonstrated superior learning efficiency, knowledge, and skill transfer. The TER of 0.79 substituted for 47.4 minutes of operating room time when IVR was used for 60 minutes. ClinicalTrials.gov Identifier: NCT04404010.

Teaching humanitarian surgery: Filling the gap between NGO needs and subspecialized surgery through a novel inter-university certificate

: Background: Access to surgical care is a global health burden. A broad spectrum of surgical competences is required in the humanitarian context whereas current occidental surgical training is oriented towards subspecialties. We proposed to design a course addressing the specificities of surgery in the humanitarian setting and austere environment. Method: The novelty of the course lies in the implication of academic medical doctors alongside with surgeons working for humanitarian non-governmental organizations (NGO). The medical component of the National Defense participated regarding particular topics of war surgery. The course is aimed at trained surgeons and senior residents interested in participating to humanitarian missions. Results: The program includes theoretical teaching on surgical knowledge and skills applied to the austere context. The course also covers non-medical aspects of humanitarian action such as international humanitarian law, logistics, disaster management and psychological support. It comprises a large-scale mass casualty exercise and a practical skills lab on surgical techniques, ultrasonography and resuscitation. Attendance to the four teaching modules, ATLS certification and succeeding final examinations provide an interuniversity certificate. 30 participants originating from 11 different countries joined the course. Various surgical backgrounds, training levels as well as humanitarian experience were represented. Feedback from the participants was solicited after each teaching module and remarks were applied to the following session. Overall participant evaluations of the first course session are presented. Conclusion: Teaching humanitarian surgery joining academic and field actors seems to allow filling the gap between high-income country surgical practice and the needs of the humanitarian context.

Should interventional radiology gain speciality status within the royal college of radiologists?

Interventional Radiology (IR) medicine's best kept secret will revolutionise healthcare like never before. The legacy Charles Dotter left behind not only showcases IR's pursuit of innovative and complex techniques in order to provide better treatment options for patients, it also sparked an opportunity for radiologists to use their imagination and creativity to develop IR into a speciality catering for the 21st century. By utilising imaging as well as clinical and minimal invasive surgical knowledge IRs are able to play an integral role in caring for patients in nearly all specialities.Over the past few decades, the absence of radiology in the leadership management arena has allowed other specialities to perpetuate turf wars and utilise techniques developed by IR. A concerted effort is required by the wider radiology community to address the problems faced by IR and to recognise its true potential as a speciality to further improve patient care.

Computer vision in surgery

The fields of computer vision (CV) and artificial intelligence (AI) have undergone rapid advancements in the past decade, many of which have been applied to the analysis of intraoperative video. These advances are driven by wide-spread application of deep learning, which leverages multiple layers of neural networks to teach computers complex tasks. Prior to these advances, applications of AI in the operating room were limited by our relative inability to train computers to accurately understand images with traditional machine learning (ML) techniques. The development and refining of deep neural networks that can now accurately identify objects in images and remember past surgical events has sparked a surge in the applications of CV to analyze intraoperative video and has allowed for the accurate identification of surgical phases (steps) and instruments across a variety of procedures. In some cases, CV can even identify operative phases with accuracy similar to surgeons. Future research will likely expand on this foundation of surgical knowledge using larger video datasets and improved algorithms with greater accuracy and interpretability to create clinically useful AI models that gain widespread adoption and augment the surgeon’s ability to provide safer care for patients everywhere.

Laryngeal Leukoplakia: State of the Art Review.

This state-of-the-art article reviews the epidemiology, diagnosis, and management of vocal fold leukoplakia, with focus on recent advances. It focuses on the clinical challenges that otolaryngologists face balancing both oncological efficacy and functional outcomes in leukoplakia and presents the current philosophies and techniques to consider when managing such patients. PubMed/MEDLINE. We conducted a detailed review of publications related to vocal cord and laryngeal leukoplakia, dysplasia, hyperkeratosis, leukoplakia endoscopy, and leukoplakia management focusing specifically on oncologic outcomes, voice preservation, current and emerging diagnosis, and management techniques. There has been a paradigm shift away from performing "vocal cord stripping" procedures that can cause irreversible hoarseness toward voice preservation surgery while achieving comparable oncologic control. Surgical technical and instrumental developments have been designed to maximally treat superficial disease while preserving underling vibratory mucosa. Recent improvements in histopathological grading systems and advances in biomarker classification may allow for improved oncologic risk stratification. Furthermore, improvements in endoscopic imaging capabilities and contact endoscopy are currently being studied for their potential diagnostic significance. To optimally manage vocal fold leukoplakia, the otolaryngologist should become familiar with the oncologic implications of the disease and the importance of obtaining pathologic diagnosis to rule out malignancy. In addition, the surgeon should maintain surgical techniques and knowledge of available instruments and lasers that can assist in surgical management while prioritizing the preservation of vibratory tissue and voice quality. Finally, the surgeon and the patient should understand the clinical importance of routine endoscopic surveillance.

Learning to teach: A novel method for assessing surgical trainees’ teaching and operative knowledge

BackgroundThe purpose of this study was to investigate the feasibility of a simulated teaching activity as an assessment of surgical knowledge and teaching competencies. MethodsIn this prospective observational study, 15 residents and 1 fellow in the Department of Surgery watched three video clips of laparoscopic cholecystectomies and provided feedback to a participant learner. Qualitative and statistical analysis identified differences in surgical knowledge and teaching strategies. ResultsAs compared to senior trainees, junior trainees were more likely to speculate on the learner’s actions (p = 0.033), identify which actions looked correct (p = 0.028), and speculate more on the learner’s thoughts (p = 0.02). Senior trainees noted case difficulty more frequently (p = 0.028), identified more actions that looked incorrect (p = 0.004), and speculated more about the learner’s emotions (p = 0.033). ConclusionsA simulated teaching scenario successfully assessed operative and teaching competencies, suggesting a novel assessment method.

Feasibility of Using Posterior Auricular Artery as Landmark for Identification of Facial Nerve Trunk in Parotid Surgery: A Cadaver Study.

Despite good surgical knowledge of the anatomy of parotid gland and meticulous surgical technique, the incidence of facial palsy in parotid surgeries is up to 26.7% transient and 1.7% complete facial palsy(1). The risk of facial palsy increases further in malignant and revision cases. Superficial parotidectomy was done in 14 cadaveric hemi faces in 10 cadavers. Posterior auricular artery and its stylomastoid branch was dissected and facial nerve trunk was identified in all cases. The relationship of posterior auricular artery along with its stylomastoid branch with the facial nerve trunk was studied and recorded. Posterior auricular artery was found running inferior to the facial nerve trunk in 12 cadaveric dissection while the posterior auricular artery was found crossing below the main trunk of facial in 2 cadaver dissection. The average distance between PAA and facial nerve trunk was 7 mm (2-14 mm) Stylomastoid artery was found arising from Posterior auricular artery in 12 of 14 and it was found running medial to the facial nerve trunk in all the 8 cadavers. Post auricular artery can be used as another landmark for identification of the main trunk of facial nerve in parotid surgeries.

Periocular rejuvenation using hyaluronic acid fillers

The eyes and periocular region are critical for emotive display and play a key role in social interactions. This region includes the upper and lower eyelids, brow-lid complex, and lid-cheek complex. Perturbances in this area can lead to a prematurely aged appearance and patients complain of emotive misinterpretation. It often shows the earliest signs of facial aging, leading to a tired, sad, or angry appearance. With the evolution of medical and surgical knowledge on facial aging, there has been a shift from isolated volume reducing interventions for periorbital aging to volume replacement techniques. The treatment of periocular aging is multifactorial and often includes resurfacing, chemodenervation, surgical interventions, and volumization. The minimally-invasive, office-based nature of fillers has resulted in their increased popularity and filler placement has become one of the most commonly performed cosmetic oculoplastic interventions. With a multitude of fillers emerging over the past decade or so, facial plastic surgeons have been equipped with the means to address age-related periorbital hollowing and skeletonization in an outpatient setting. An appropriate knowledge of periocular anatomy, types of fillers, proper injection technique, and management of potential complications is required for safe injection and to achieve optimal aesthetic outcomes. This paper reviews the use of hyaluronic acid fillers for periocular rejuvenation.

Improving the Management of Adult Patients with Acute Ankle Fractures in Malawi: An Examination of Providers’ Knowledge and Treatment Strategies

Category:Trauma; Ankle; OtherIntroduction/Purpose:The burden of trauma is growing worldwide, especially in low-income countries. In Malawi, ankle fractures are common and may receive inadequate treatment due to limited surgical capacity and provider knowledge of evidence- based treatment guidelines. We sought to examine ankle fracture management in Malawi, identify providers’ knowledge gaps, and address these knowledge gaps in ways that were relevant to the Malawian context.Methods:This study had three phases. First, we performed a baseline assessment of orthopaedic providers’ knowledge of anatomy, injury identification, and ideal treatment methods. Second, we observed providers’ treatment strategies while they cared for adult patients with ankle fractures over a five-week period at a large central hospital. We performed blinded, post-hoc reviews of patient x-rays and compared our treatment recommendations to the plans and rationales of Malawian providers. Third, we implemented an educational course addressing the knowledge gaps we identified, performed pre- and post-course knowledge assessments, and launched a standardized protocol for ankle fracture management in Malawi.Results:In our baseline assessment, we identified significant knowledge gaps in identification of common injuries on x-ray and ideal treatment practices. In our observations of treatment practices, 17/49 patients (35%) met operative criteria based on evidence-based guidelines but did not receive operative treatment by Malawian providers. For 7/17 (41%) of these patients, Malawian providers believed nonoperative treatment was ideal. In our educational course, 51/61 participants (84%) performed better between the pre- and post-course assessments. Overall scores improved from a mean of 66% to 77%, an improvement of 5.2/49 questions (95% CI 3.8-6.6, p<0.001). Providers could identify one more injury correctly out of 6 that were tested (95% CI 0.6-1.6, p<0.001), and identify one more ideal treatment out of 7 (95% CI 0.5-1.4, p<0.001).Conclusion:In Malawi, ankle fractures are common, and most are treated non-operatively. This is partly due to resource limitations, but also due to gaps in provider knowledge and lack of treatment standardization. Here we demonstrated a comprehensive approach to examining the challenges to providing adequate care, as well as the successful implementation of an intervention to improve care capacity nationwide.

Teaching middle ear anatomy using a novel three-dimensional papercraft model

BackgroundThe middle ear is a complex anatomical space which is difficult to interpret from two-dimensional imagery. Appropriate surgical knowledge of the area is required to operate, yet current anatomical teaching methods are costly and hard to access for the trainee.MethodsA papercraft 3D design involving anatomical elements added separately to a model was designed, and then peer-validated by medical students and junior doctors. Preliminary quantitative assessment was performed using an anatomical labelling questionnaire, with six students given a lecture to act as a control. Qualitative feedback was also gathered.Results18 participants were recruited for the study. A total of 12 models were constructed by 6 medical students and 6 junior doctors. 6 medical students received a lecture only. Qualitative feedback was positive and suggested the model improved knowledge and was useful, yet timing and complexity were issues. Students scored, on average, 37% higher after completing the model, with junior doctors also improving anatomical knowledge, though these differences were not significant (p > 0.05).ConclusionsIn this initial investigation, the model was shown to be an engaging way to learn anatomy, with the tactile and active nature of the process cited as benefits. Construction of the model improved anatomical knowledge to a greater extent than a classical lecture in this study, though this difference was not significant. Further design iterations are required to improve practical utility in the teaching environment, as well as a larger study.

Legacy of COVID‐19 – the opportunity to enhance surgical services for patients with colorectal disease

The COVID-19 crisis has undoubtedly taken a toll on the care of patients with colorectal disease. Elective services, be that face to face contact, endoscopy or operating all but ceased during the pandemic.

The Impact of Hospital/University Affiliation on Research Productivity Among US-Based Authors in the Fields of Trauma, Surgical Critical Care, Acute Care, and Emergency General Surgery.

Research productivity is critical to academic surgery and essential for advancing surgical knowledge and evidence-based practice. We aim to determine if surgeon affiliation with top US universities/hospitals (TOPS) is associated with increased research productivity measured by numbers of peer-reviewed publications in PubMed (PMIDs). A bibliometric analysis was performed for PMIDs. Affiliated authors who published in trauma surgery (TS), surgical critical care (SCC), acute care surgery (ACS), and emergency general surgery (EGS) were evaluated for publications between 2015 and 2019, and lifetime productivity. Our analysis included 3443 authors from 443 different institutions. Our main outcome was PMIDs of first author (FA) and senior author (SA) in each field (2015-2019) and total lifetime publications. Significant differences exist between PMIDs from TOPS vs non-TOPS in FA-TS (1.34 vs 1.23, P = .001), SA-TS (1.71 vs 1.46, P < .001), total SA-PMIDs (44.10 vs 26.61, P < .001), and SA-lifetime PMIDs (90.55 vs 59.03, P < .001). There were no significant differences in PMIDs for FA or SA-SCC, FA or SA-ACS, FA or SA-EGS, FA-total PMIDs 2015-2019, or FA-lifetime PMIDs (P > .05 for all). There were significantly higher TS PMIDs among FAs and SAs affiliated with top US institutions in 2015-2019, along with higher total PMIDs (2015-2019) and lifetime PMIDs. These findings are of significance to future graduate medical applicants and academic surgeons who need to make decisions about training and future career opportunities.

Complications of Dentoalveolar Surgery

This article explores how to prevent and manage complications of dentoalveolar surgery. Many complications are avoidable. Surgical skills and knowledge of anatomy play an important role in prevention of complications. Prevention starts with detailed history and physical examination of the patient. Key to perioperative management of patients is risk assessment. Without a proper history and physical examination, the clinician is unable to assess the risk of performing surgery and anesthesia for each patient. Some illnesses and medications increase the risk of complications. The following complications are discussed: alveolar osteitis, displacement, fracture, hemorrhage, infection, nonhealing wound, oroantral communication, swelling, and trismus.

The New PGY-1Year: Lessons Learned.

Describe the ACGME's changes to the PGY-1year in urology and discuss the benefits and challenges faced by training programs. There are no publications detailing the integration of the PGY-1year in urology; however, response of other surgical subspecialties to their own integration has been studied. Benefits of integration include earlier exposure to techniques and knowledge specific to urology, potentially leading to increased preparedness for next steps in training and exams. Program directors have more flexibility to select rotations relevant to urology. Resident wellness may be improved as interns are incorporated into the department earlier and can help distribute the workload for senior residents. Challenges include decreased exposure to basic surgical knowledge and skills, decreased camaraderie with general surgery colleagues, and difficulties associated with evaluating interns who are spending limited time with urology departments. Overall, the change seems to have a positive impact on urological training.

The complicated gallbladder—is old-school treatment an alternative?

Since implementation of the laparoscopic approach for removal of the gallbladder in the early 90s, a shift in numbers from open cholecystectomy (OC) to laparoscopic cholecystectomy (LC) has been observed. Despite initial reservations, LC has become the most favoured technique in the past 3 decades. Consecutive technical improvements support this trend. Considering this development, the question regarding the relevance of OC nowadays inevitably arises. This study represents a literature review performed in PubMed. Laparoscopic cholecystectomy has evolved to be the leading technique for cholecystectomy. This technique has become well established in elective as well as in acute indications. However, concomitant to increasing numbers of performed LC, the proportion of performed OC is declining, leading to a decreasing expertise and a lack in training in OC nowadays. However, in complex situations, when the operation strategy has to be changed to maintain patient safety, conversion to OC is the most common strategy. Owing to past and current developments, open cholecystectomy can hardly be assumed to be common surgical knowledge anymore. Hence, OC as bail-out strategy in cases of intraoperative difficulties must be critically evaluated. From this point of view, alternative patient management and treatment concepts should be considered to maintain patient safety.

Why Do They Leave? Challenges to Retention of Surgical Clinical Officers in District Hospitals in Malawi.

Background: Low- and middle-income countries (LMICs) are the worst affected by a lack of safe and affordable access to safe surgery. The significant unmet surgical need can be in part attributed to surgical workforce shortages that disproportionately affect rural areas of these countries. To combat this, Malawi has introduced a cadre of non-physician clinicians (NPCs) called clinical officers (COs), trained to the level of a Bachelor of Science (BSc) in Surgery. This study explored the barriers and enablers to their retention in rural district hospitals (DHs), as perceived by the first cohort of COs trained to BSc in Surgery level in Malawi. Methods: A longitudinal qualitative research approach was used based on interviews with 16 COs, practicing at DHs, during their BSc training (2015); and again with 15 of them after their graduation (2019). Data from both time points were analysed and compared using a top-down thematic analysis approach. Results: Of the 16 COs interviewed in 2015, 11 intended to take up a post at a DH following graduation; however, only 6 subsequently did so. The major barriers to remaining in a DH post as perceived by these COs were lack of promotion, a more attractive salary elsewhere; and unclear, stagnant career progression within surgery. For those who remained working in DH posts, the main enablers are a willingness to accept a low salary, to generate greater opportunities to engage in additional earning opportunities; the hope of promotional opportunities within the government system; and greater responsibility and recognition of their surgical knowledge and skills as a BSc-holder at the district level. Conclusion: The sustainability of surgically trained NPCs in Malawi is not assured and further work is required to develop and implement successful retention strategies, which will require a multi-sector approach. This paper provides insights into barriers and enablers to retention of this newly-introduced cadre and has important lessons for policy-makers in Malawi and other countries employing NPCs to deliver essential surgery.

Abu Al-Qasim Al-Zahrawi (936–1013 CE), Icon of Medieval Surgery

Abu al-Qasim Al-Zahrawi (936-1013 common era [CE]), also known in the West as Albucasis, was a great Arab physician and surgeon of the late 10th and early 11th centuries CE. He is best known for his surgical knowledge and expertise. His greatest contribution to medicine is the Kitab al-Tasrif, which includes thirty treatises on medical sciences. His early and great contributions to the field of surgery were seminal. For his endeavors in this field, a number of surgeons and scholars have dubbed him the "Father of Operative Surgery".

The Surgical Knowledge “Growth Curve”: Predicting ABSITE Scores and Identifying “At-Risk” Residents

Resident performance on the American Board of Surgery In-Training Examination (ABSITE) is used for evaluation of surgical knowledge and guides resident selection for institutional remediation programs. Remediation thresholds have historically been based on ABSITE percentile scores; however, this does not account for predictors that can impact a resident's exam performance. We sought to identify predictors of yearly ABSITE performance to help identify residents "at-risk" for performing below their expected growth trajectory. The knowledge of the residents, as measured by standardized ABSITE scores, was modeled as a function of the corresponding postgraduate year via a linear mixed effects regression model. Additional model covariates included written USMLE-1-3 examination scores, gender, number of practice questions completed, and percentage correct of practice questions. For each resident, the predicted ABSITE standard score along with a 95% bootstrap prediction interval was obtained. Both resident-specific and population-level predictions for ABSITE standard scores were also estimated. The study was conducted at a single, large academic medical center (Massachusetts General Hospital, Boston, MA). Six years of general surgery resident score reports at a single institution between 2014 and 2019 were deidentified and analyzed. A total of 376 score reports from 130 residents were analyzed. Covariates that had a significant effect on the model included USMLE-1 score (PGY1: p = 0.013; PGY2: p = 0.007; PGY3: p = 0.011), USMLE-2 score (PGY1: p < 0.001; PGY2: p < 0.001; PGY3: p < 0.001; PGY4: p < 0.001; PGY5: p = 0.032), male gender (PGY1: p = 0.003; PGY2: p < 0.001; PGY3: p < 0.001; PGY4: p = 0.008), and number of practice questions completed (p=0.003). Five residents were identified as having "fallen off" their predicted knowledge curve, including a single resident on 2 occasions. Population prediction curves were obtained at 7 different covariate percentile levels (5%, 10%, 25%, 50%, 75%, 90%, and 95%) that could be used to plot predicted resident knowledge progress. Performance on USMLE-1 and -2 examinations, male gender, and number of practice questions completed were positive predictors of ABSITE performance. Creating residency-wide knowledge growth curves as well as individualized predictive ABSITE performance models allows for more efficient identification of residents potentially at risk for poor ABSITE performance and structured monitoring of surgical knowledge progression.
