Background

Pre-internship boot camps have become popular platforms to rapidly teach skills to surgical interns. This study aimed to analyze psychomotor skill retention four months after completing a boot camp program.

Methods

Surgical interns (n?=?20) took a baseline pre-test and then trained to proficiency (based on time and errors) for 5 knot tying, 4 simple suturing, and 2 running suturing tasks during a three-day boot camp. Three months later, all interns took a retention test.

Results

Proficiency scores significantly improved on all task types from pre-test to post test and significantly regressed on all task types from post-test to retention test. Normalized scores decreased as the tasks became more complex (knot tying?=?93.5, simple suturing?=?89.1, running suturing?=?85.2, p?=?0.05).

Conclusions

Boot camp style training can rapidly teach fundamental surgical skills to novices; however, skills regress significantly over time with a greater degree of regression seen on more complex skills.  相似文献

Background

This study aimed to identify differences in pattern recognition skill among individuals with varying surgical experience.

Methods

Participants reviewed laparoscopic cholecystectomy videos of various difficulty, and paused them when the cystic duct or artery was identified to outline each structure on the monitor. Time taken to identify each structure, accuracy and work load, which was assessed using the NASA-Task Load Index (TLX), were compared among the three groups.

Results

Ten students, ten residents and eight attendings participated in the study. Attendings identified the cystic duct and artery significantly faster and more accurately than students, and identified the cystic artery faster than residents. The NASA-TLX score of attendings was significantly lower than that of students and residents.

Conclusions

Attendings identified anatomical structures faster, more accurately, and with less effort than students or residents. This platform may be valuable for the assessment and teaching of pattern recognition skill to novice surgeons.

Short summary

Accurate anatomical recognition is paramount to proceeding safely in surgery. The assessment platform used in this study differentiated recognition skill among individuals with varing surgical experience.  相似文献

Introduction

"See one, do one, teach one" has represented the model for surgical education for over a century, however recent changes in education have reduced autonomy in training. The goal of this study was to assess the impact of autonomy on learning a procedural skill.

Methods

Senior medical students were randomized and trained to performance a vascular anastomosis utilizing progressive autonomy vs. constant supervision. Performance was tested using videotaped technical grading and anastomotic pressure testing.

Results

Mean baseline performance times and technical ratings were similar in both groups. Final completion times was faster in the autonomy group, 14:03min vs. 19:09min (p?=?0.02). Final technical ratings were similar, 40.0 vs. 39.2points (max?=?50), for each group and both demonstrated similar improvement in leak test against a standardized sample.

Conclusion

Teaching a procedure, as a final step in graded autonomy, results in superior performance in timing while maintaining equal technical performance compared to trainees with less autonomy.  相似文献

Case series.

Introduction

Upper extremity (UE) trauma and subsequent immobilization affects functional performance.

Purpose of the Study

Determine the usefulness and feasibility of unilateral hand training (UHT) on improving functional performance in patients with UE trauma.

Methods

Nine participants received UHT within 10 days of immobilization. Functional performance, dexterity, grip, and pinch strength were measured at initial and 4-week visits. Qualitative interviews were coded to develop themes.

Results

All Jebsen-Taylor hand function test subtests improved from pretest to post-test. Disabilities of the Arm, Shoulder and Hand scores of all 9 participants improved. Functional performance was more impaired for participants with dominant UE injury. Four themes emerged: participants were forced to alter or avoid most daily activities, had an increased dependency on others, took longer to perform activities, and felt UHT decreased the impact of UE trauma on function.

Discussion

Functional performance was impaired for all participants. Participants believed that UHT was useful and contributed to improved function.

Conclusion

This case series tracked a comprehensive intervention based on a holistic activities of daily living framework that considered the nuances of individual complexities of immobilization following hand trauma. Knowledge from this study supports an early intervention like UHT to educate clients on effective strategies to improve immediate activities of daily living functioning and potentially prevent longer term impairments.  相似文献

Background

Though the importance of physician non-technical (NT) skills for safe patient care is recognized, NT skills of medical students, our future physicians, has received little attention. This study aims to investigate the relationship of medical student NT skills and clinical performance during acute care team simulation (ACTS).

Methods

Forty-one medical students participated in ACTS. A nurse confederate facilitated and evaluated clinical performance. Two raters assessed participants’ NT skills using an adapted NT assessment tool and overall NT skills score was calculated. Regressions predicting clinical performance using NT constructs were conducted.

Results

Overall NT skills score significantly predicted students’ clinical performance (r2?=?0.178, p?=?0.006). Four of the five individual NT constructs also significantly predicted performance: communication (r2?=?0.120, p?=?0.027), situation awareness (r2?=?0.323, p?<?0.001), leadership (r2?=?0.133, p?=?0.019), and decision making (r2?=?0.163, p?=?0.009).

Conclusions

Medical student NT skills can predict clinical performance during ACTS. NT skills assessments can be used for targeted education for better feedback to students.  相似文献

Background

Emergency surgical airway is a low frequency, high risk clinical scenario. Implementing a simulation-based curriculum may bridge the gap in surgical training and address quality assurance/performance improvement (QAPI) needs.

Methods

We designed and implemented an Advanced Surgical Airway Curriculum (ASAC) modeled after proficiency-based training. General Surgery residents and student nurse anesthetists were enrolled. Evaluation consisted of cognitive tests, procedure checklists and questionnaire.

Results

In total, 78 participants successfully completed the ASAC. Trainees agreed that the curriculum provided the cognitive and psychomotor skills necessary to perform both an open and needle cricothyroidotomy.

Conclusions

In the age of increased patient safety concerns, QAPI initiatives can serve as a driver for simulation-based training curricula, with particular focus on individualized, active learning. This may be particularly useful in high risk, low frequency scenarios in which the traditional method of “See one, Do one, Teach one,” is not feasible.  相似文献

Background

We hypothesized that medical experts would concur the American College of Surgeons/Association for Surgical Education Medical Student Simulation-based Surgical Skills Curriculum (“ACS/ASE Curriculum”) could be used to teach and assess Entrustable Professional Activities (EPAs).

Methods

A “crosswalk” was created between ACS/ASE Curriculum modules and eight EPAs. Medical education experts participated in a Delphi process regarding feasibility of using the modules for teaching and assessing EPAs.

Results

Twenty-eight educators from six clinical fields participated. There was consensus that five of the EPAs could be taught and assessed by the ACS/ASE Curriculum. A median of nine hours per month outside the surgical clerkship was recommended for skills training.

Conclusions

The ACS/ASE Curriculum lays the framework for implementing select EPAs into medical student education. Experts recommended increased time for skills training with incorporation of the modules into the first three years of medical education, with assessments planned in the third to fourth years.  相似文献

Purpose

Video feedback and faculty feedback has been shown to improve surgical performance; however, consistent access to faculty is challenging. We studied the utility of structured peer-feedback (PF) compared to faculty-feedback (FF) during acquisition of basic and intermediate surgical skills.

Methodology

Two randomized non-inferiority trials were conducted with 1st (n?=?30) and 2nd year (n?=?29) medical students learning skin-lesion excision and closure (S), and single-layer hand-sewn bowel anastomosis (B), respectively. Five attempts were performed. PF participants used an Objective Structured Assessment of Technical Skills tool to guide feedback. Blinded raters assessed video-recorded performance, time and Integrity of the completed task were also assessed.

Results

For both tasks performance by PF was comparable to FF (P?=?0.111). Both groups improved significantly: performance (B:P?<?0.0001, S:P?=?0.035), time (B:P?=?0.043, S:P?<?0.0001) and integrity (B:P?<?0.0001, S:P?<?0.032).

Conclusion

Structured peer-feedback is equivalent to faculty-feedback in the acquisition of basic and intermediate surgical skills, giving students freedom to practice independently.  相似文献

Clinical measurement (reliability and validity) study.

Introduction

Forearm supination is important in many daily activities and is thus measured by therapists and researchers usually with a universal goniometer. DrGoniometer, a SmartPhone application, has been validated for other joint angles in the body.

Purpose of the Study

To establish the reliability and validity of DrGoniometer (CDM S.r.L, Cagliari, Italy) for measuring forearm supination in healthy populations and those with forearm fractures.

Methods

Participants had sustained a distal radius fracture that was treated non-surgically. Forearm supination of the participant’s fractured (n = 30) and healthy forearm (n = 30) was measured using DrGoniometer and the universal goniometer by two assessors. The assessors were blinded to each other’s measurements and their own previous measurements. Reliability was established by calculating Intra-class Correlation Coefficients, standard error of measurement and minimal detectable change. The validity of DrGoniometer was established against the universal goniometer using Pearson’s correlation co-efficient.

Results

Intra-rater reliability of both DrGoniometer and the universal goniometer was high for both fractured and healthy forearms (ICCs ranged from 0.74-0.88). Inter-rater reliability of both DrGoniometer and the universal goniometer was also high in the fractured forearm group (0.76 and 0.72 respectively), but low in the healthy forearm group (0.34 and 0.42 respectively). Correlation between the tools was excellent across the fractured and healthy forearm groups (0.94 and 0.93 respectively).

Discussion

Both goniometers demonstrated good-to-excellent intrarater and iner-rater reliability except in the healthy forearm group where both goniometers demonstrated poor inter-rater reliability which could be due to assessor instructions. The speed the photo can be taken and the digital record obtained are valuable aspects of DrGoniometer.

Conclusion

DrGoniometer is a valid, alternate tool for measuring forearm supination.  相似文献

Objective

We incorporated a hybrid-abdominal wound simulation to teach/assess the acquisition of three essential clinical skills in the ACS/ASE Medical Student Simulation-based Surgical Skills Curriculum.

Method

Third year students (N?=?43) attended a workshop based on the ACS/ASE surgical skills curriculum for drain care/removal, staple removal and Steri-Strip application. Following a didactic session and demonstration using a simulated patient, student skill acquisition was assessed using the ACS/ASE module rating tool. Student interest/perceived usefulness of the workshop was evaluated using Keller's Motivational Survey.

Results

We used median scores to identify low proficiency (n?=?20; scores 17–28) and high proficiency (n?=?23; scores 29–35) groups. The high proficiency group was more knowledgeable, performed better drain care, had a higher global score and was more confident than the low proficiency group. The students rated the workshop highly based on the Keller's Motivational Survey.

Conclusion

All students were proficient in the procedure tasks and communication skills and most felt that the course was beneficial. The ACS/ASE Medical Student Simulation-based Surgical Skills Curriculum was successfully integrated into our third year surgical clerkship.  相似文献

Introduction

A salvaged limb is one that has undergone a major traumatic injury, followed by repeated surgical attempts in order to avoid amputation. Psychological recovery for individuals with lower extremity limb salvage has been examined in a number of studies. However, psychosocial reactions for individuals with upper extremity (UE) limb salvage are understudied in the literature.

Purpose of the Study

The purpose of this study was to explore the process of psychosocial adaptation for 3 trauma cases after UE limb salvage.

Methods

The Reactions to Impairment and Disability Inventory was used to assess psychosocial adaptation. Physical function outcomes (pain, range of motion, edema, sensation, and dexterity) are presented. The Disabilities of the Arm, Shoulder, and Hand measure was used to assess perceived disability. Medical and rehabilitation history are discussed for each case, in order to provide in-depth understanding of the impact of these injuries.

Results

Reactions to injury varied across the cases; however, outcomes suggest that psychosocial adaptation may be influenced by the experience of pain, the ability to participate in valued roles and activities, and having a supportive social network.

Discussion

For this population, therapists may consider emphasizing pain management, focusing on client-centered goals and interventions, and facilitating peer support. Providers should closely monitor patients for signs of poor adaptation, such as hand-hiding behaviors.

Conclusions

This study is among the first to examine psychological outcomes for the UE limb salvage population. Future research would be beneficial to provide deeper understanding of the psychosocial challenges for these individuals.  相似文献

Introduction

Previous data examining the effect of gender on surgical trainee autonomy is lacking. We hypothesized that female general surgery residents have less autonomy than males during laparoscopic cases.

Methods

We retrospectively reviewed factors associated with level of guidance needed during laparoscopic procedures as reported on intraoperative procedure feedback forms and on FLS tasks from one institution from 2013 to 2016. Data collected included resident and attending gender, level of guidance needed, PGY level, case characteristics, resident intraoperative performance, and skills lab FLS performance. Univariate and multivariate analyses were performed using a mixed-effects regression model.

Results

We analyzed data from 106 PGY1-PGY5 residents (51% Female) and 104 attendings (26% Female). Female resident gender was associated with more intraoperative guidance in univariate (p?=?0.019) and multivariate analysis (p?=?0.034). Technical performance between genders was similar.

Conclusions

This study demonstrated gender-based inequality in intraoperative autonomy even after controlling for technical performance, PGY level, and case factors.  相似文献

Introduction

Common provocative maneuvers to differentiate thumb carpometacarpal (CMC) osteoarthritis from other sources of pain are the grind, metacarpal (MC) flexion, and MC extension tests. A maneuver known as the pressure-shear test is described here.

Purpose of the study

To compare the diagnostic value of the grind, metacarpal flexion, metacarpal extension, and pressure-shear tests for CMC osteoarthritis of the thumb.

Methods

The diagnostic accuracy of each test was compared in 127 thumbs from 104 patients. Sensitivity, specificity, and predictive values of each test were calculated. In a secondary analysis, polychoric correlation coefficients were used to assess the correlation of each test with severity defined by Eaton-Littler stage.

Results

The overall diagnostic accuracy of the thumb MC grind, pressure-shear, flexion, and extension tests were 70%, 98%, 47%, and 55%, respectively. The sensitivities were 64%, 99%, 36%, and 46%, respectively, and specificities were 100%, 95%, 100%, and 100%, respectively. For the diagnosis of Thumb CMC arthritis, the MC pressure-shear test was superior overall in terms of overall diagnostic accuracy and sensitivity, while having comparable specificity to the other maneuvers.

Conclusion

The pressure-shear test was found to be superior to the commonly used grind maneuver and the provocative maneuvers of MC flexion and extension tests to confirm diagnosis of CMC osteoarthritis.  相似文献

Study Design

A within-subject research design was used in this study. The difference of the range of motion (ROM) with and without ulnar nerve block was analyzed.

Introduction

For the clinical evaluation of the functional effects of ulnar nerve palsy at the hand the relevance of clinical tests is in discussion.

Purpose of the Study

The aim of the study was to evaluate the predictive value of 2 clinical tests for a simulated ulnar nerve lesion by motion analysis with a sensor glove.

Methods

In 28 healthy subjects, dynamic measurements of the finger joints were performed by a sensor glove with and without ulnar nerve block at the wrist. In the 0° metacarpophalangeal (MCP) stabilization test, the subjects were asked to stabilize the MCP joints actively in 0° while moving the interphalangeal joints, whereas at the 90° MCP stabilization test, the subjects stabilized the MCP joints actively in the 90° position.

Results

In the 0° MCP stabilization test, no remarkable changes of the ROM were found at the MCP joints; at the proximal interphalangeal joints 2-5, the ROM decreased with ulnar nerve block, significantly at the index, middle, and ring fingers (P < .05). In the 90° MCP stabilization test, the average ROM of the MCP joints 2-5 significantly increased with ulnar nerve block (P < .05), whereas at the PIP joints, the average ROM decreased (P < .05).

Discussion

The 90° MCP stabilization test had a high predictive value for the discrimination between healthy subjects and subjects with a simulated peripheral ulnar nerve lesion.

Conclusions

The results could be relevant for the determination of the functional effect of ulnar nerve palsy and the quantification of clawing in hand rehabilitation.

Introduction

The high degree of motion that occurs at the thumb metacarpophalangeal (MCP) joint must be taken into account when immobilizing a partially torn or repaired thumb ulnar collateral ligament.

Purpose of the Study

To determine the efficacy of a radial-based thumb MCP-stabilizing orthosis in resisting abduction across the thumb ulnar collateral ligament.

Methods

Ten fresh cadaveric hands were mounted to a custom board. An anteroposterior radiograph of the thumb was obtained with a 2 N preload valgus force applied to the thumb, and the angle between the Kirschner wires was measured as a baseline. Subsequently, 20, 40, 60, 80, and 100 N valgus forces were applied 15 mm distal to the MCP joint. Anteroposterior radiographs of the thumb were obtained after each force was applied. The angle of displacement between the wires was measured and compared with the baseline angle. The angles were measured with an imaging processing tool. A custom radial-based thumb MCP-stabilizing orthosis was fashioned for each cadaveric thumb by a certified hand therapist. The aforementioned loading protocol was then repeated.

Results

The radial-based thumb MCP-stabilizing orthosis significantly reduced mean abduction angles at each applied load.

Discussion

We found that our orthosis, despite being hand-based and leaving the thumb IP and CMC joints free, significantly reduced mean abduction angles at each applied load.

Conclusions

This investigation provides objective evidence that our radial-based thumb MCP-stabilizing orthosis effectively reduces the degree of abduction that occurs at the thumb MCP joint up to at least 100 N.

Introduction

Development of extensor tendon adhesions is a common complication after intra-articular metacarpal head fracture. Whenever these adhesions cannot be mobilized by rehabilitation, tenolysis should be considered. However, the decision for tenolysis is often delayed. When the rehabilitation program comes to a plateau and clinical examination may not be sufficient to find out the cause, dynamic ultrasound (US) can show where the gliding mechanism is disrupted and help clinicians to give an accurate decision for determining the next steps.

Purpose of the Study

To determine the role of dynamic US during hand rehabilitation.

Methods

A 22-year-old woman presented with a fifth metacarpal intra-articular head fracture. Ten days after the surgery (open reduction and internal fixation) the hand rehabilitation program was commenced. After the third week, the metacarpophalangeal (MP) joint range of motion (ROM) gradually diminished. Dynamic US near the level of fifth MP joint revealed diminished extensor tendon excursion and capsular thickening.

Results

Considering physical and sonographic findings, surgical tenolysis and capsular release was planned. After surgery, the DIP, PIP and MP joints reached full passive ROM.

Conclusion(s)

Ultrasound is a quick and practical way to diagnose tendon adhesions. With this report, the authors suggest that clinicians may use dynamic US, especially in times when the patient comes to plateau during hand rehabilitation.

Introduction

Upper limb orthoses worn during functional tasks are commonly used in pediatric neurologic rehabilitation, despite a paucity of high-level evidence.

Purpose of the Study

The purpose of this study was to investigate if a customized functional wrist orthosis, when placed on the limb, leads to an immediate improvement in hand function for children with cerebral palsy or brain injury.

Methods

A 2-group randomized controlled trial involving 30 children was conducted. Participants were randomized to either receive a customized functional wrist orthosis (experimental, n = 15) or not receive an orthosis (control, n = 15). The box and blocks test was administered at baseline and repeated 1 hour after experimental intervention, with the orthosis on if randomized to the orthotic group.

Results

After intervention, there were no significant differences on the box and blocks test between the orthotic group (mean, 10.13; standard deviation, 11.476) and the no orthotic group (mean, 14.07; standard deviation, 11.106; t[28], ?0.954; P = .348; and 95% confidence interval, ?12.380 to 4.513).

Discussion

In contrast to the findings of previous studies, our results suggest that a functional wrist orthosis, when supporting the joint in a ‘typical’ position, may not lead to an immediate improvement in hand function.

Conclusions

Wearing a functional wrist orthosis did not lead to an immediate improvement in the ability of children with cerebral palsy or brain injury to grasp and release. Further research is needed combining upper limb orthoses with task-specific training and measuring outcomes over the medium to long term.  相似文献

Introduction

Chemotherapy-induced peripheral neuropathy (CIPN) usually affects both sensory and motor function of hands and feet, resulting in impaired skilled hand function (e.g., typing a keyboard). However, quantitative and objective evaluations for this condition have not been established.

Purpose of the Study

We evaluated skilled hand function using a kinematic analysis and investigated relationships among hand kinematic function and the clinical sensory and motor features of CIPN.

Study Designs

Clinical measurement.

Methods

Twelve CIPN patients and 12 age-matched control participants were enrolled. We recorded their reach and grasp movements using a three-dimensional measurement system, and calculated the normalized jerk of these movements as quantitative indexes of skilled hand function. Additionally, we used the number of sequential hand grip–release cycles in 10 seconds as an evaluation of clinical motor function.

Results

Our kinematic analyses revealed significant difference in normalized jerk of grasp movement (CIPN: 3.7 ± 0.2, control: 3.4 ± 0.1; P = .005), but this was not the case for reach movement (CIPN: 2.5 ± 0.1, control: 2.5 ± 0.2; P = .43), indicating that the distal part of the forearm is particularly affected in CIPN. Such disturbed grasp movement was directly correlated with poor scores on the hand grip–release test and the sensory tests.

Discussion

We revealed deficit impaired hand function objectively and quantitatively in CIPN patients using a kinematic analysis. Further, the hand grip test could represent such kinematic abnormality and could be useful for evaluating skilled hand function of CIPN patients.

Conclusions

Our kinematic and clinical measurements objectively and quantitatively evaluate skilled hand function in individuals with CIPN in clinical settings.

Introduction

The push-off test (POT) was recently conceived and found to be reliable and valid for assessing weight bearing through injured wrist or elbow. However, further research with larger sample can lend credence to the preliminary findings supporting the use of the POT.

Purpose of the Study

This study examined the interrater reliability, construct validity, and measurement error for the POT in patients with wrist conditions.

Methods

Participants with musculoskeletal (MSK) wrist conditions were recruited. The performance on the POT, grip isometric strength of wrist extensors was assessed. The shortened version of the Disabilities of the Arm, Shoulder and Hand and numeric pain rating scale were completed. The intraclass correlation coefficient assessed interrater reliability of the POT. Pearson correlation coefficients (r) examined the concurrent relationships between the POT and other measures. The standard error of measurement and the minimal detectable change at 90% confidence interval were assessed as measurement error and index of true change for the POT.

Results

A total of 50 participants with different elbow or wrist conditions (age: 48.1 ± 16.6 years) were included in this study. The results of this study strongly supported the interrater reliability (intraclass correlation coefficient: 0.96 and 0.93 for the affected and unaffected sides, respectively) of the POT in patients with wrist MSK conditions. The POT showed convergent relationships with the grip strength on the injured side (r = 0.89) and the wrist extensor strength (r = 0.7). The POT showed smaller standard error of measurement (1.9 kg). The minimal detectable change at 90% confidence interval for the POT was 4.4 kg for the sample.

Conclusions

This study provides additional evidence to support the reliability and validity of the POT. This is the first study that provides the values for the measurement error and true change on the POT scores in patients with wrist MSK conditions. Further research should examine the responsiveness and discriminant validity of the POT in patients with wrist conditions.  相似文献
