Development of a Sensor Technology to Objectively Measure Dexterity for Cardiac Surgical Proficiency. Ann Thorac Surg 2024; 117:635-643. [PMID: 37517533 DOI: 10.1016/j.athoracsur.2023.07.013] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/23/2023] [Revised: 05/04/2023] [Accepted: 07/11/2023] [Indexed: 08/01/2023]
Abstract
BACKGROUND Technical skill is essential for good outcomes in cardiac surgery. However, no objective methods exist to measure dexterity while performing surgery. The purpose of this study was to validate sensor-based hand motion analysis (HMA) of technical dexterity while performing a graft anastomosis within a validated simulator. METHODS Surgeons at various training levels performed an anastomosis while wearing flexible sensors (BioStamp nPoint, MC10 Inc) with integrated accelerometers and gyroscopes on each hand to quantify HMA kinematics. Groups were stratified as experts (n = 8) or novices (n = 18). The quality of the completed anastomosis was scored using the 10 Point Microsurgical Anastomosis Rating Scale (MARS10). HMA parameters were compared between groups and correlated with quality. Logistic regression was used to develop a predictive model from HMA parameters to distinguish experts from novices. RESULTS Experts were faster (11 ± 6 minutes vs 21 ± 9 minutes; P = .012) and used fewer movements in both dominant (340 ± 166 moves vs 699 ± 284 moves; P = .003) and nondominant (359 ± 188 moves vs 567 ± 201 moves; P = .02) hands compared with novices. Experts' anastomoses were of higher quality compared with novices (9.0 ± 1.2 MARS10 vs 4.9 ± 3.2 MARS10; P = .002). Higher anastomosis quality correlated with 9 of 10 HMA parameters, including fewer and shorter movements of both hands (dominant, r = -0.65, r = -0.46; nondominant, r = -0.58, r = -0.39, respectively). CONCLUSIONS Sensor-based HMA can distinguish technical dexterity differences between experts and novices, and correlates with quality. Objective quantification of hand dexterity may be a valuable adjunct to training and education in cardiac surgery training programs.

Abstract
BACKGROUND Traditionally, novice perfusionists learn and practice clinical skills, during live surgical procedures. The profession's accrediting body is directing schools to implement simulated cardiopulmonary bypass (CPB) into the curriculum. Unfortunately, no CPB simulation models have been validated. Here we describe the design and application of a CPB simulation model. METHODS A CPB patient simulator was integrated into a representative operative theater and interfaced with a simple manikin, a heart-lung machine (HLM), clinical perfusion circuitry, and equipment. Participants completed a simulation scenario designed to represent a typical CPB procedure before completing an exit survey to assess the fidelity and validity of the experience. Questions were scored using a 5-point Likert scale. RESULTS Participants (n = 81) contributed 953 opinions on 40 questions. The participants reported that the model of simulated CPB (1) realistically presented both the physiologic and technical parameters seen during CPB (n = 347, mean 4.37, SD 0.86), (2) accurately represented the psychological constructs and cognitive mechanisms of the clinical CPB (n = 139, mean 4.24, SD 1.08), (3) requires real clinical skills and reproduces realistic surgical case progression (n = 167, mean 4.38, SD 0.86), and (4) would be effective for teaching, practicing, and assessing the fundamental skills of CPB (n = 300, mean 4.54, SD 0.9). Participants agreed that their performance in the simulation scenario accurately predicted their performance in a real clinical setting (n = 43, mean 4.07, SD 1.03) CONCLUSION: This novel simulation model of CPB reproduces the salient aspects of clinical CPB and may be useful for teaching, practicing, and assessing fundamental skills.

Abstract
INTRODUCTION A recent needs assessment in Canadian cardiac surgery programs identified the desire for a coronary artery bypass (CABG) and aortic valve replacement (AVR) simulation model for home practice. We aimed to develop and assess a portable, adjustable task trainer for cardiac surgical skills with high functional task alignment. METHODS Intraoperative measurements were taken from patients undergoing elective CABG and AVR (N = 30). Measurements were taken in 3 axes and used to create a chest cavity that resembles the mediastinal constraints of a patient undergoing CABG and AVR. The task trainer is adjustable on the following 3 levels: (1) size of the incision, (2) depth of the chest, and (3) relative position of coronary artery or aortic valve model within the chest. Three groups (novices, intermediates, and experts) of cardiac surgery members evaluated the task trainer for functional task alignment and construct validity. RESULTS The CABG and AVR model had high functional task alignment. There was a high satisfaction for both models and all participants would recommend the AVR and CABG model as an educational tool. Performance time significantly differed between the groups for both models (CABG: P = 0.032 and AVR: P = 0.001), as well as number of errors (CABG: P = 0.04 and AVR: P = 0.043). CONCLUSIONS Using real patient data, we were able to develop an adjustable task trainer for training principles of CABG and AVR. Our pilot study provides preliminary sources of evidence for validity and future study will look to assess transferability of skill to the operating room.

JOURNAL OF ULTRASOUND IN MEDICINE : OFFICIAL JOURNAL OF THE AMERICAN INSTITUTE OF ULTRASOUND IN MEDICINE 2023; 42:1103-1112. [PMID: 36367343 DOI: 10.1002/jum.16125] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/02/2022] [Revised: 10/11/2022] [Accepted: 10/20/2022] [Indexed: 06/16/2023]
Abstract
OBJECTIVES To introduce an ultrasound training program for fetal palate screening by using a sequential sector scan through the oral fissure to train less experienced doctors and to investigate its effectiveness. METHODS Twenty doctors and several women at approximately 20-28 weeks of gestation with singleton pregnancies who provided informed consent were enrolled. The training program consisted of theory and practice training, several tests, and two surveys. Trainees were tested before training and immediately after training; for the latter, each item with a score that was less than 60% of the full score was again used for training with a reconstructed plan. Finally, a post-training test was completed. RESULTS The median theory scores, median practice scores, median language competence scores, and median self-assessment scores all increased significantly from the pre-training to post-training tests (P < .01). The median completion time for fetal palate scans decreased significantly from the pre-training to post-training tests (P < .01). The median questionnaire scores were 5.00 for pragmatism, 4.00 for content, 4.00 for scientific nature, and 5.00 for effectiveness. CONCLUSIONS The training program for fetal palate screening can effectively standardize and improve doctors' scans for fetal palates. In addition, the program feasibly allows for the incorporation of the scan sequence into fetal palate screening.

Abstract
Thoracic surgery is an increasingly expanding field, and the addition of national screening programs has resulted in increasing operative numbers and complexity. Thoracic surgery overall has an approximately 2% mortality and 20% morbidity with common specific complications including persistent air leak, pneumothorax, and fistulas. The nature of the surgery results in complications being unique to thoracic surgery and often very junior members of the surgical team feel underprepared to deal with these complications after very little exposure during their medical school and general surgical rotations. Throughout medicine, simulation is being increasingly used as a method to teach the management of complicated, rare, or significant risk occurrences and has shown significant benefits in learner confidence and outcomes. In this mini review we explain the learning theory and benefits of simulation learning. We also discuss the current state of simulation in thoracic surgery and its potential future in aiding complication management and patient safety.

Reduction in ionizing radiation exposure during minimally invasive anterior plate osteosynthesis of distal radius fracture: Naive versus deliberate practice. HAND SURGERY & REHABILITATION 2021; 41:194-198.

Abstract
This study aimed to decrease surgeon exposure to ionizing radiation through a new learning technique, "deliberate practice", which consists in improving performance by setting goals with feedback. The hypothesis was that exposure to ionizing radiation during distal radius fracture surgery using the minimally invasive plate osteosynthesis (MIPO) technique decreased faster with "deliberate" practice than with "naïve" practice. Radiographic dosimetry was measured in the first 30 fractures operated on by MIPO by 6 surgeons. The first 3 surgeons operated "naively" (Group 1) and the next 3 according to the "deliberate" procedure (Group 2). Group 2 received weekly feedback (number of exposed hands, number of fluoroscopic views, exposure duration, and X-ray dose). An expert, using fluoroscopic images and surgical videos, provided suggestions for improvement. Mean number of exposed hands was 23.66 in Group 1 and 1.9 in Group 2. Mean number of fluoroscopic views was 78.31 and 35.0, respectively. Mean X-ray exposure time was 74.34 and 32.89 s, respectively. Mean dosimetry was 1.40 mGy (and 0.59 mGy, respectively. The hypothesis was thus confirmed: dosimetry decreased faster in Group 2 than in Group 1. Teaching this deliberate practice should be generalized, to decrease the growth phase and increase the plateau phase of the learning curve.

Abstract
Teaching multiple, evolving surgical approaches to thoracic surgical residents at a time of decreasing surgeon volume, increasing scrutiny of quality, greater demands on surgical efficiency, and reduced resident work hours requires a new mindset and new methods of education. The challenge presented to general thoracic surgeon educators and residents is explained, and encouragement is drawn from the examples of previous educational crises and their solutions.

Abstract
Principles of surgical training have not changed, but methods of training are evolving very fast. Online tools are being adopted in both knowledge and skills training for surgical residents. As a result, to evaluate the outcome of these tools, online assessment is also developing. Knowledge resources are very diverse ranging from lectures, webinars, surgical videos to three-dimensional planning and printing. Skills resources include virtual reality simulators, remote skills training and interdisciplinary teamwork. Assessment of E-learning tools can be performed using online questions, task-based simulations, branching scenarios and online interviews/discussions. In thoracic surgery, video assisted thoracic surgery (VATS) lobectomy simulator has been developed and it appears to be an important tool for minimally invasive thoracic surgery education. Training programs incorporate e-Learning in their curriculum and online training and assessment will become an important part of thoracic surgical training as well.

Abstract
Interventional pulmonology (IP) is a maturing subspecialty of pulmonary medicine. The robust innovation in technology demands standardization in IP training with both disease and technology driven training. Simulation based training should be considered a part of IP training as seen in other procedural and surgical subspecialties. Procedure volume is a component of training; however, this does not guarantee or translate into competency for learners. Basic competency skills can be assessed using standardized well validated assessment tools designed for various IP procedures including flexible bronchoscopy, endobronchial ultrasound guided transbronchial needle aspiration (EBUS TBNA), rigid bronchoscopy and chest tube placement; however, further work is needed to validate tools in all procedures as new technologies are introduced beyond fellowship training. Currently there are at least 39 IP fellowship programs in the United States (US) and Canada which has led to improved training by accreditation of programs who meet rigorous requirements of standardized curriculum and procedural volume. The challenge is to be innovative in how we teach globally with intention and how to best integrate new evolving technology training for those not only during fellowship training but also beyond fellowship training.

Abstract
What is important to think about in surgical education and technical skills training? Technical skills training is grounded in social cognitive theory and the concepts of modeling and self-efficacy. Cognitive and nontechnical learning is critical to supplement the overall proficiency of the surgical learner in performing an operation. Technical learning is cemented by deliberate practice and there is benefit to productive struggle and failure. External cognitive load should be minimized to maximized operative skills advancement.
