Criteria for the Operating Room Confirmation of the Diagnosis of Hip Instability: The Results of an International Expert Consensus Conference.

PURPOSE: The purpose of this study was to establish an international expert consensus on operating room findings that aid in the diagnosis of hip instability. METHODS: An expert panel was convened to build an international consensus on the operating room diagnosis/confirmation of hip instability. Seventeen surgeons who have published or lectured nationally or internationally on the topic of hip instability were invited to participate. Fifteen panel members completed a pre-meeting questionnaire and agreed to participate in a 1-day consensus meeting on May 15, 2021. A review of the literature was performed to identify published intraoperative reference criteria used in the diagnosis of hip instability. Studies were included for discussion if they reported and intraoperative findings associated with hip instability. The evidence for and against each criteria was discussed, followed by an anonymous voting process. For consensus, defined a priori, items were included in the final criteria set if at least 80% of experts agreed. RESULTS: A review of the published literature identified 11 operating room criteria that have been used to facilitate the diagnosis of hip instability. Six additional criteria were proposed by panel members as part of the pre-meeting questionnaire. Consensus agreement was achieved for 8 criteria, namely ease of hip distraction under anesthesia (100.0% agreement), inside-out pattern of chondral damage (100.0% agreement), location of chondral damage on the acetabulum (93.3% agreement), pattern of labral damage (93.3% agreement), anteroinferior labrum chondral damage (86.7% agreement), perifoveal cartilage damage (97.6% agreement), a capsular defect (86.7% agreement), and capsular status (80.0% agreement). Consensus was not achieved for 9 items, namely ligamentum teres tear (66.7% agreement), arthroscopic stability tests (46.7% agreement), persistent distraction after removal of traction (46.7% agreement), findings of examination under anesthesia (46.7% agreement), the femoral head divot sign (40.0% agreement), inferomedial synovitis (26.7% agreement), drive-through sign (26.7% agreement), iliopsoas irritation (26.7% agreement) and ligamentum teres-labral kissing lesion (13.3% agreement). All experts agreed on the final list of 8 criteria items reaching consensus. CONCLUSION: This expert panel identified 8 criteria that can be used in the operating room to help confirm the diagnosis of hip instability. LEVEL OF EVIDENCE: Level V expert opinion.

Comparison of learning outcomes of interprofessional education simulation with traditional single-profession education simulation: a mixed-methods study.

BACKGROUND: Interprofessional collaborative practice is essential for meeting patients' needs and improving their health outcomes; thus, the effectiveness of interprofessional education (IPE) should be clearly identified. There is insufficient evidence in the literature to determine the outcomes of IPE compared to traditional single-profession education (SPE). This study aimed to compare the outcomes of IPE and SPE during a simulation training course. METHODS: The study design was a mixed-methods, incorporated cross-over design and a qualitative survey. A total of 54 students including 18 medical students and 36 nursing students were recruited from March to April 2019. The 4-week simulation course was designed based on Kolb's experimental learning theory and Bandura's social learning theory. Participants were evenly divided into group 1 (received IPE-learning followed by SPE-learning), and group 2 (received SPE-learning followed by IPE-learning). Students' medical task performance, team behavior performance, teamwork attitude, and patient safety attitude were collected at pretest, mid-test, and posttest. Descriptive statistics and repeated measures analysis of variance were used. End-of-study qualitative feedback was collected, and content analysis was performed. RESULTS: Both groups demonstrated moderate-to-large within-group improvements for multiple learning outcomes at mid-test. Group 1 students' medical task performance (F = 97.25; P < 0.001) and team behavior performance (F = 31.17; P < 0.001) improved significantly. Group 2 students' medical task performance (F = 77.77; P < 0.001), team behavior performance (F = 40.14; P < 0.001), and patient safety attitude (F = 6.82; P < 0.01) improved significantly. Outcome differences between groups were nonsignificant. Qualitative themes identified included: personal factor, professional factor, interprofessional relationship, and learning. The IPE program provided students with exposure to other professions and revealed differences in expertise and responsibilities. CONCLUSION: IPE-simulation and SPE-simulation were effective interventions that enabled medical and nursing students to develop critical medical management and team behavior performance. IPE-simulation provided more opportunities for improving competencies in interprofessional collaborative practice. In circumstances with limited teaching resources, SPE-simulation can be an acceptable alternative to IPE-simulation.

An Exploratory Study of Sectra Table Visualization Improves the Effectiveness of Emergency Bedside Echocardiography Training.

OBJECTIVES: Echocardiography is an essential tool in emergency medicine, and its training is the most challenging of all types of bedside ultrasound (US) training. This study investigated the effectiveness of the Sectra Table (Sectra AB, Linköping, Sweden), an anatomy visualization and collaboration tool, in improving the quality of echocardiography training for emergency medicine physicians. METHODS: We conducted an exploratory prospective observational study from 2015 to 2017 and enrolled 66 trainees who participated in a 2.5-day bedside US course organized by the emergency department (ED) of Peking Union Medical College Hospital. The study participants underwent 2 different training programs: the first group received standard training, and the second group was trained with Sectra Table experiences integrated into the echocardiography training curriculum. After the training sessions, both groups were evaluated for their hands-on echocardiography performance. RESULTS: The new training program with the Sectra Table significantly increased trainees' self-confidence in performing bedside echocardiography. The Sectra Table trainees had a higher performance rating than the trainees in the traditional program, with a mean total assessment score of 40.5 versus 26.5 for traditional training (P < .01). The improved performance was evident for all subcategories of echocardiography. The higher performance rating of the Sectra Table trainees was also statistically significant after adjusting for confounders, including prior training experiences, baseline confidence in independently performing ED US examinations, the number of ED US examinations performed, years in ED practice, and physician seniority. CONCLUSIONS: Our analysis suggests that integrating the Sectra Table into echocardiography training may improve the effectiveness of training programs.

Airway Management: A Structured Curriculum for Critical Care Transport Providers.

OBJECTIVE: Airway assessment and management are vital skills for the critical care transport provider. Nurses and paramedics often enter a transport program with limited or no exposure to airway management. Many programs lack a structured curriculum to show skill competence. Optimal methods in the development of airway management competence and the frequency of training needed to maintain skills have not been clearly defined. Because of this lack of standardization, the actual level of competence in both new and experienced critical care transport providers is unknown. METHODS: A pretest, post-test repeated measures approach using an online curriculum combined with a deliberate practice model was used. Competence in airway management was measured using 3 evaluation points: static mannequin head, simulation scenario, and the live patient. RESULTS: A convenience sample of critical care transport providers participated (N = 9). Knowledge improvement was significant, with a higher percentage of participants scoring above 85% on the post-test compared with the pretest (P = .028). Mean scores in completion of the airway checklist pre- versus postintervention were significantly increased on all 3 evaluation points (P < .001 for all comparisons). Significant changes were noted in the response profile evaluating participants' confidence in their ability to verbalize indications for endotracheal intubation (P < .05). CONCLUSION: The development of a standardized, blended learning curriculum combined with deliberate simulation practice and rigorous assessment showed improvements in multiple areas of airway assessment and management.

Efficacy of a physiotherapy rehabilitation program for individuals undergoing arthroscopic management of femoroacetabular impingement - the FAIR trial: a randomised controlled trial protocol.

BACKGROUND: Femoroacetabular impingement is a common cause of hip/groin symptoms and impaired functional performance in younger sporting populations and results from morphological abnormalities of the hip in which the proximal femur abuts against the acetabular rim. Many people with symptomatic femoroacetabular impingement undergo arthroscopic hip surgery to correct the bony abnormalities. While many case series over the past decade have reported favourable surgical outcomes, it is not known whether formal rehabilitation is needed as part of the management of patients undergoing this surgical procedure. This randomised controlled trial will investigate the efficacy of a progressive physiotherapist-supervised rehabilitation program (Takla-O'Donnell Protocol) in improving health-related quality of life, physical function and symptoms in individuals undergoing arthroscopic management of femoroacetabular impingement. METHODS/DESIGN: 100 people aged 16-35 years undergoing hip arthroscopy for symptomatic femoroacetabular impingement will be recruited from surgical practices in Melbourne, Australia and randomly allocated to either a physiotherapy or control group. Both groups will receive written information and one standardised post-operative physiotherapy visit whilst in hospital as per usual care. Those in the physiotherapy group will also receive seven individual 30-minute physiotherapy sessions, including one pre-operative visit (within 2 weeks of surgery) and six post-operative visits at fortnightly intervals (commencing two weeks after surgery). The physiotherapy intervention will incorporate education and advice, manual techniques and prescription of a progressive rehabilitation program including home, aquatic and gym exercises. The control group will not receive additional physiotherapy management. Measurements will be taken at baseline (2 weeks pre-operatively) and at 14 and 24 weeks post-surgery. Primary outcomes are the International Hip Outcome Tool and the sports subscale of the Hip Outcome Score at 14 weeks post-surgery. Secondary outcomes include the Copenhagen Hip and Groin Outcome Score, the activities of daily living subscale of the Hip Outcome Score, the Heidelberg Sports Activity Score, a modified Tegner Activity Scale and participant-perceived overall change. DISCUSSION: The findings from this randomised controlled trial will provide evidence for the efficacy of a specific physiotherapist-supervised rehabilitation program in improving outcomes following arthroscopic management of symptomatic femoroacetabular impingement.

Overcoming barriers in online workshop development: an ELITE experience.

The Emerging Learning and Integrated Technologies Education (ELITE) Faculty Development Program created eight online workshops to assist nurse educators in using technology within their organization's nurse education program. Continuing education units were provided for completion of the individual online workshops. The ELITE program worked through several barriers to transform content that was previously presented during face-to-face workshops into standalone online offerings. Barriers and implementation strategies for the on-site to online transition included restructuring workshop objectives, keeping current with rapid technology changes, altering a course management system to meet the needs of the program and the learner, and crafting independent practice opportunities for the online learner. The online workshop development experience of the ELITE program may assist other continuing education and staff development professionals who are updating their program offerings or pursuing online education for the first time.

Simulation in Nurse Anesthesia Educational Programs: A Report by the AANA Simulation Subcommittee.

Simulation is an integral part of the healthcare educational landscape and a key element in the future of graduate professional education. For the past three decades, simulation-based educational methodology has been gaining popularity in nurse anesthesia educational programs (NAEP). There is currently limited objective evidence documenting modalities used or educational outcomes addressed through simulation in NAEPs. In 2018, the American Association of Nurse Anesthesiology (AANA) established a Simulation Subcommittee of the AANA Education Committee and tasked the group with two primary goals: 1) to gain a better understanding of the current state of simulation education and 2) to review responses with regard to how NAEPs could best incorporate simulation elements within their curriculum to meet requirements while adhering to the guidelines of the Council on Accreditation of Nurse Anesthesia Educational Programs. A survey tool was developed and distributed to all programs to assess the utilization of simulation, available simulation resources, ongoing faculty development efforts, and barriers to use of this educational approach. Survey results indicated that simulation is valued as an effective method within NAEPs for a variety of teaching and learning activities and is utilized to support achievement of both technical and nontechnical learning outcomes for student registered nurse anesthetists.

Quantitative cotyloid fossa thickness and proximity to obturator neurovascular bundle: implications for arthroscopic ligamentum teres reconstruction.

The aim of the present study was to report the in vivo thickness of the cotyloid fossa at the acetabular ligamentum teres (LT) attachment and investigate the clearance of the obturator neurovascular bundle. Fifty-five consecutive patients undergoing a total hip arthroplasty for hip osteoarthritis were included. The thickness of the cotyloid fossa was measured at the acetabular LT attachment using a standard depth gauge. The minimal distance (clearance) of the obturator neurovascular bundle to the center of the acetabular LT attachment was measured in 7 patients (14 hips) who also underwent a computed tomography angiography. The average thickness of the cotyloid fossa at the acetabular LT attachment was 4.1 ± 2.3 (range: 1-10) mm. The obturator vein was closest to the acetabular LT attachment, but the clearance was more than the defined safe zone of 15 mm in all cases. Based on the current findings, it can be assumed that bone anchors might not be suitable for fixation of the graft in LT reconstruction (LTR) and an alternative implant such as a cortical button should be considered. Acetabular fixation of the graft with a 12-mm cortical button is relatively safe concerning injury to obturator neurovascular structures. The results of the present study provide a better understanding of the cotyloid fossa anatomy and might be relevant for surgeons who perform arthroscopic LTR.

Anesthesia Management for Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy Surgery on Short-Term Patient Outcomes.

The aim of this retrospective study was to understand the impact of anesthesia management for the patients under cytoreductive surgery and hyperthermic intraperitoneal chemotherapy surgery (CRS+HIPEC). The perioperative electronic medical records of 833 CRS+HIPEC surgical cases from two hospitals were analyzed to study the characteristics of shortterm patient outcomes in hospitals for CRS+HIPEC. Older age, higher American Society of Anesthesiologists (ASA) score, male gender, longer anesthesia time, higher Peritoneal Cancer Index (PCI), and higher intraoperative blood loss predict the prolonged hospital stay for patients. Older age, higher ASA score, longer anesthesia time, higher PCI, higher intraoperative fluid administration, lower intraoperative propofol dosage, higher intraoperative blood loss, and failed extubation predict the prolonged intensive care unit stay. Older age, male gender, longer anesthesia time, higher ASA score, higher PCI, higher intraoperative opioid dosage, and higher intraoperative blood loss predict the higher degree postoperative complications. We also observed that implementation of enhanced recovery after surgery protocols may improve patient outcomes for CRS+HIPEC. These results need further confirmation from future prospective randomized studies.

Comparison of simulation-based interprofessional education and video-enhanced interprofessional education in improving the learning outcomes of medical and nursing students: A quasi-experimental study.

BACKGROUND: Use of interprofessional education has greatly expanded and is widely used to foster interprofessional collaborative practice competency in health professionals, especially during medical emergencies. Identifying the interprofessional education delivery mode that can maximize learning outcomes within available resources is crucial for achieving the sustainability of an interprofessional education program. OBJECTIVES: To examine the learning outcomes of simulation-based interprofessional education and video-enhanced interactive discussion interprofessional education modules and to analyze the variable costs between these two interprofessional education modules. DESIGN: A prospective quasi-experimental study. SETTING: A medical university in Northern Taiwan. PARTICIPANTS: 24 medical students and 48 nursing students enrolled in a 4-week simulation-based interprofessional education or video-enhanced interactive discussion interprofessional education program. METHODS: Students' medical task performance, critical medical task performance, team behavior performance, and interprofessional collaboration attitude were examined at the pretest and posttest by using an objective structured checklist and team performance rating scale with a hands-on simulation model and structured questionnaires. The variable costs for simulation-based interprofessional education and video-enhanced interactive discussion interprofessional education were estimated upon the completion of the course. RESULTS: All learning outcomes significantly improved for both the groups from the pretest to posttest. After the intervention, the simulation-based interprofessional education group exhibited significantly higher scores in medical task performance, critical medical task performance and team behavior performance than the video-enhanced interactive discussion interprofessional education group at the posttest. No significant difference was noted in interprofessional collaboration attitude between the groups. Cost analysis revealed that the simulation-based interprofessional education program was approximately two times more expensive in terms of staffing costs and required 1.3 times greater space charges than the video-enhanced interactive discussion interprofessional education program. CONCLUSION: Both simulation-based interprofessional education and video-enhanced interactive discussion interprofessional education modules effectively improved medical and nursing students' medical task performance, critical medical task performance and team behavior performance. The simulation-based interprofessional education group had more favorable learning outcomes, but the associated costs were higher. Educators should consider both learning outcomes and cost when choosing a design strategy simulation-based interprofessional education vs. video-enhanced interactive discussion interprofessional education for interprofessional education module development.

Multi-center development and testing of a simulation-based cardiovascular assessment curriculum for advanced practice nurses.

Cardiovascular assessment skills are deficient among advanced practice nursing students, and effective instructional methods to improve assessment skills are needed. The purpose of this study was to develop, implement, and evaluate outcomes of a cardiovascular assessment curriculum for advanced practice nurses at four institutions. Each institution used a one-group pre-to-post-intervention design. Educational interventions included faculty-led, simulation-based case presentations using the Harvey cardiopulmonary patient simulator (CPS), and independent learning sessions using the CPS and a multimedia, computer-based CD-ROM program. Outcome measures included a 31-item cognitive written exam, a 13-item skills checklist used in each of a three-station objective structured clinical exam, learner self-efficacy and satisfaction survey, instructor satisfaction and self-efficacy survey, and a participant logbook to record practice time using the self-learning materials. Thirty-six students who received the simulation-based training showed statistically significant pre-to-post-test improvement in cognitive knowledge and cardiovascular assessment skills.

Endoscopic treatment of iliopsoas impingement after total hip arthroplasty: a minimum 2-year follow-up and comparison of tenotomy performed at the acetabular rim versus lesser trochanter.

Iliopsoas impingement is an underdiagnosed cause of groin pain after total hip arthroplasty (THA), being responsible for 4.4% of cases. Non-surgical treatment may be effective in ∼50% of cases. Endoscopic surgery has gained popularity as an option for non-responsive patients because of its non-invasive characteristics, faster recovery and encouraging results. This study compares two different sites of endoscopic psoas tenotomy performed following THA: at the edge of the acetabulum (AR) versus at the lesser trochanter (LT). This is a retrospective review of prospectively collected data from a single-surgeon case series. Thirty-five iliopsoas tenotomy cases which had >24-month follow-up were identified. There were 21 tenotomies at the lesser trochanter. Demographic data, preop and postop pain, mHHS and NAHS scores, strength and patient satisfaction data were collected and analysed. Average age at the time of surgery was 62. Mean follow-up for the LT group was 49.11 months and 42.42 months for the AR group. Pain decreased significantly for both groups (P < 0.001). Both mHHS and NAHS showed superiority in the LT group, but this difference did not reach significance (P = 0.06). LT patients showed better strength with 71.42% of them having normal strength at latest follow-up, compared with 41.6% in the AR group. There were no complications in either group. Endoscopic tenotomy is a safe and reliable surgical option, giving significant pain relief and good functional outcomes. Tenotomy at the level of the lesser trochanter might be preferable since it shows better outcomes. Larger studies are necessary to achieve statistically significant results.

Treatment of Gluteal Tendinopathy: A Systematic Review and Stage-Adjusted Treatment Recommendation.

BACKGROUND: Gluteal tendinopathy is the most common lower limb tendinopathy. It presents with varying severity but may cause debilitating lateral hip pain. PURPOSE: To review the therapeutic options for different stages of gluteal tendinopathy, to highlight gaps within the existing evidence, and to provide guidelines for a stage-adjusted therapy for gluteal tendinopathy. STUDY DESIGN: Systematic review; Level of evidence, 4. METHODS: We screened Scopus, Embase, Web of Science, PubMed, PubMed Central, Ovid MEDLINE, CINAHL, UpToDate, and Google Scholar databases and databases for grey literature. Patient selection, diagnostic criteria, type and effect of a therapeutic intervention, details regarding aftercare, outcome assessments, complications of the treatment, follow-up, and conclusion of the authors were recorded. An assessment of study methodological quality (type of study, level of evidence) was also performed. Statistical analysis was descriptive. Data from multiple studies were combined if they were obtained from a single patient population. Weighted mean and range calculations were performed. RESULTS: A total of 27 studies (6 randomized controlled trials) with 1103 patients (1106 hips) were included. The mean age was 53.7 years (range, 17-88 years), and the mean body mass index was 28.3. The ratio of female to male patients was 7:1. Radiological confirmation of the diagnosis was most commonly obtained using magnetic resonance imaging. Reported treatment methods were physical therapy/exercise; injections (corticosteroids, platelet-rich plasma, autologous tenocytes) with or without needle tenotomy/tendon fenestration; shockwave therapy; therapeutic ultrasound; and surgical procedures such as bursectomy, iliotibial band release, and endoscopic or open tendon repair (with or without tendon augmentation). CONCLUSION: There was good evidence for using platelet-rich plasma in grades 1 and 2 tendinopathy. Shockwave therapy, exercise, and corticosteroids showed good outcomes, but the effect of corticosteroids was short term. Bursectomy with or without iliotibial band release was a valuable treatment option in grades 1 and 2 tendinopathy. Insufficient evidence was available to provide guidelines for the treatment of partial-thickness tears. There was low-level evidence to support surgical repair for grades 3 (partial-thickness tears) and 4 (full-thickness tears) tendinopathy. Fatty degeneration, atrophy, and retraction can impair surgical repair, while their effect on patient outcomes remains controversial.

Certified registered nurse anesthetist and anesthesiologist assistant education programs in the United States.

In Japan, a relative shortage of practicing anesthesiologists continues to be a national issue. To address this issue, some Japanese medical institutions have started developing curriculums to train non-physician perioperative anesthesia personnel, including nurse practitioners and perianesthesia nurses. We urgently need to establish a national standard for the education programs that train these extended non-physician anesthesia care providers. A certified registered nurse anesthetist educational program at a large academic medical center in the United States is described in detail as a reference. Highly systematic educational programs using simulation, didactics, and full clinical subspecialty rotations are ideal if not easily achievable in many current training institutions in Japan. Anesthesia assistant education programs in the United States can be used as an additional reference to create a national educational program in Japan.

Arthroscopic utilization of ChondroFiller gel for the treatment of hip articular cartilage defects: a cohort study with 12- to 60-month follow-up.

ChondroFiller gel is an absorbable collagen implant. It serves as a protective cover for the cartilage defects, allowing chondrocyte migration into the lesion. The implant consists of collagen (Type I) and is derived from veterinary monitored rats. This study evaluates the use of ChondroFiller gel in the treatment of cartilage lesions during hip joint arthroscopy. A prospective study was conducted on a group of 26 adult patients. All patients had an existing femoroacetabular impingement together with acetabular cartilage lesions >2 cm2. All patients underwent hip arthroscopic surgery and the lesions were treated using ChondroFiller gel. The cartilage tissue healing was evaluated postoperatively using MRI. A total of 26 patients, including 5 females and 21 males, all with articular cartilage lesions, were included in the study. Cartilage healing conditions were evaluated for all patients, and the difference between pre- and post-surgery conditions was statistically significant. The follow-up scores have been acquired from 21 out of initial 26 patients (2 were disqualified after receiving THR, 3 could not be reached by researchers) after 3, 4 and 5 years consecutively with 17/21 patients having good/excellent results. The use of ChondroFiller gel during arthroscopy of the hip for acetabular cartilage lesions is an effective treatment technique. Encouraging long-term results have been observed, but further research on larger group of patient is required to better assess the full value of this technique. Patients with pre-existing osteoarthritis (Tönnis 2-3) have poor results.

The outcome of hip arthroscopy in Australian football league players: a review of 27 hips.

PURPOSE: The purpose of this study was to investigate on hip pathology found at hip arthroscopy in Australian Football League (AFL) players and describe our current treatments and outcomes. METHODS: From 2003 to 2008, 24 consecutive AFL players (27 hips) had arthroscopic hip surgery by use of the lateral position. Patients were assessed preoperatively and postoperatively with the modified Harris Hip Score (MHHS) and Nonarthritic Hip Score (NAHS) and postoperatively with a satisfaction survey. RESULTS: All hips were available for review. The mean duration of follow up was 22 months (range, 6 to 60 months). The mean age was 22 years (range, 16 to 29 years). The mean body mass index was 24 points (range, 21 to 26 points). The mean traction time was 21 minutes (range, 11 to 60 minutes). The most common pathology was a rim lesion, affecting 93% of cases. Microfracture was performed in 22%. Synovitis was found in 70%, and this was most commonly associated with a rim lesion. Labral pathology was present in 33%, the most common of which was labral separation. On the femoral side, 81% had cam impingement and underwent a femoral neck ostectomy. Rim lesions and labral pathology were the most commonly associated lesions. Also seen were loose os acetabuli in 7% and loose bodies in 7%. The former were associated with labral tears and required repair. The MHHS and NAHS improved in all patients postoperatively, and they maintained their improvement from 1 year up to 4 years. In all but 1 case, the players returned to playing at the AFL level and were satisfied with their outcome. CONCLUSIONS: Using hip arthroscopy, we have observed high satisfaction levels and return to preinjury levels of play in all but 1 case. Postoperative hip scores (MHHS and NAHS) have improved significantly, and this improvement has been maintained for up to 4 years. LEVEL OF EVIDENCE: Level IV, therapeutic case series.

Critical thinking skills in nursing students: comparison of simulation-based performance with metrics.

AIM: This paper is a report of an examination of the relationship between metrics of critical thinking skills and performance in simulated clinical scenarios. BACKGROUND: Paper and pencil assessments are commonly used to assess critical thinking but may not reflect simulated performance. METHODS: In 2007, a convenience sample of 36 nursing students participated in measurement of critical thinking skills and simulation-based performance using videotaped vignettes, high-fidelity human simulation, the California Critical Thinking Disposition Inventory and California Critical Thinking Skills Test. Simulation-based performance was rated as 'meeting' or 'not meeting' overall expectations. Test scores were categorized as strong, average, or weak. RESULTS: Most (75.0%) students did not meet overall performance expectations using videotaped vignettes or high-fidelity human simulation; most difficulty related to problem recognition and reporting findings to the physician. There was no difference between overall performance based on method of assessment (P = 0.277). More students met subcategory expectations for initiating nursing interventions (P ≤ 0.001) using high-fidelity human simulation. The relationship between videotaped vignette performance and critical thinking disposition or skills scores was not statistically significant, except for problem recognition and overall critical thinking skills scores (Cramer's V = 0.444, P = 0.029). There was a statistically significant relationship between overall high-fidelity human simulation performance and overall critical thinking disposition scores (Cramer's V = 0.413, P = 0.047). CONCLUSION: Students' performance reflected difficulty meeting expectations in simulated clinical scenarios. High-fidelity human simulation performance appeared to approximate scores on metrics of critical thinking best. Further research is needed to determine if simulation-based performance correlates with critical thinking skills in the clinical setting.

Effects of opting-out from federal nurse anesthetists' supervision requirements on anesthesiologist work patterns.

OBJECTIVE: To estimate the impact of opting-out from Medicare supervision requirements for certified registered nurse anesthetists (CRNAs) on anesthesiologists' work patterns. DATA SOURCES/STUDY SETTING: Secondary data from two national surveys of anesthesiologists and the Area Health Resource File. STUDY DESIGN: We use a matching difference-in-difference regression which contrasts the change in work patterns for anesthesiologists in California, which dropped supervision requirements, to the change for similar anesthesiologists. Key outcome variables include the number of weekly hours worked, the type of work done, and type of care delivery teams. DATA COLLECTION/EXTRACTION METHODS: Self-reported national survey data drawn from members of the American Society of Anesthesiologists. PRINCIPAL FINDINGS: Anesthesiologists in California saw no change in time spent working or time spent supervising CRNAs. There was a decrease in direct care clinical work hours along with a shift in working more in intraoperative care, a decrease in postoperative care, and an increase in the percentage of cases supervising residents. CONCLUSIONS: Anesthesiologists had small but real responses to California's decisions to opt-out of the physician supervision requirement for CRNAs, doing more work in intraoperative care and less outside of the operating room. Total hours worked saw no change.

Preserving the chondrolabral junction reduces the rate of capsular adhesions.

The operative treatment of pincer-type femoroacetabular impingement (FAI) has become an increasingly more common procedure. Classically, the labrum is incised at the chondrolabral junction (CLJ), or a concurrent tear is extended to allow access to the acetabular rim facilitating acetabuloplasty. The labrum is subsequently repaired using suture anchors. More recently, acetabuloplasty has been performed without incising the labrum and negating the need to use suture anchors. The aim of this study is to determine whether preserving the CLJ reduces the incidence of revision hip arthroscopy for the treatment of capsulolabral adhesions. This retrospective study compared two cohorts of patients undergoing hip arthroscopy for pincer-type FAI from August 2002 to April 2015. The groups analysed were patients undergoing acetabuloplasty with labral repair (LR) and those with no labral repair (NLR). The revision rates and causes for revision were compared using the χ2 analysis. There were 1010 cases in total. Acetabuloplasty with LR was performed in 546 hips (519 patients), while acetabuloplasty with NLR was performed in 464 hips (431 patients). In the LR group, there were 54 (9.9%) revisions, 25 (46%) of which were due to capsulolabral adhesions. The NLR group had 36 (7.8%) revisions with six (17%) due to capsulolabral adhesions. Preserving the CLJ, thereby avoiding the need for drilling and the insertion of suture anchors, when performing an acetabuloplasty for pincer-type FAI, significantly reduces the rate of symptomatic adhesions requiring revision arthroscopy.

A novel and simple classification for ligamentum teres pathology based on joint hypermobility.

Ligamentum teres (LT) pathology (including synovitis, partial and complete tears) is common at the time of hip arthroscopy with a reported prevalence of 51-90%. Currently, there are four published classifications of LT injuries and tears. The majority focuses on differentiating partial from full thickness tears, whereas a more recently published classification also incorporates the presumed underlying mechanism of pathology. A recent review of the current classification systems found that all are deficient for lack of inclusion of what constitutes a normal ligament, lack of inclusion of synovitis as a source of pathology and lack of inclusion of hypermobility as part of the treatment algorithm. Also, the two most commonly used classification systems have only fair inter-observer reliability. Recent work has found that underlying joint hypermobility plays an important role in LT pathology and that the addition of capsular plication/suture at the time of surgery for LT pathology improves outcomes and reduces re-tear rates. In order to address these problems which have been identified with the currently available classification systems, we propose a novel and simple classification for LT pathology based on underlying joint hypermobility [as assessed by the Beighton test score (BTS)]. LT pathology is used to divide all patients into four types: 0 normal (which includes minor fraying), 1 synovitis (which would also include minor fraying), 2 partial tear and 3 complete tear. Further, all types are subdivided into two groups: Group A patients have no clinical evidence of joint hypermobility (BTS < 3), whereas Group B patients do have clinical evidence of joint hypermobility (BTS ≥ 4). On the basis of this classification system and the available literature, we have also developed a treatment algorithm for LT pathology.
