The Impact of Chronic Disease on the Corrected QT (QTc) Value in Women in a British Columbia First Nations Population

BACKGROUND

Indigenous women have higher rates of chronic disease than Indigenous men and non-Indigenous women. Long QT syndrome (LQTS) can be inherited or acquired; the latter may occur with chronic disease. A prolonged corrected QT value (QTc) is an independent risk factor for ventricular arrhythmias and sudden death, but few studies have quantified the impact of chronic disease on the QTc. We assessed the association between chronic disease and QTc prolongation in a population of First Nations women previously ascertained to study a high rate of inherited LQTS due to a unique genetic (founder) variant in their community.

METHODS

This substudy focusing on women expands on the original research where patients with clinical features of LQTS and their relatives were assessed for genetic variants discovered to affect the QTc. Medical records were retrospectively reviewed and chronic diseases documented. Using multivariate linear regression, adjusting for the effect of genetic variants, age, and QTc-prolonging medications, we evaluated the association between chronic disease and the QTc.

RESULTS

In total, 275 women were included. After adjustments, a prolonged QTc was associated with coronary artery disease (26.5 ms, 95% confidence interval [CI] 9.0-44.1 ms; P = 0.003), conduction system disease (26.8 ms, 95% CI 2.2-51.4 ms; P = 0.033), rheumatoid arthritis (28.9 ms, 95% CI 12.7-45.1 ms; P = 0.001), and type 2 diabetes mellitus (17.9 ms, 95% CI 3.6-32.3 ms; P = 0.015).

CONCLUSIONS

This quantification of the association between chronic disease and QTc prolongation in an Indigenous cohort provides insight into the nongenetic determinants of QTc prolongation. Corroboration in other populations will provide evidence for generalisability of these results.

Psychological safety in simulation: Perspectives of nursing students and faculty

BACKGROUND

As simulation education continues to grow, more consideration has been given to creating and maintaining a psychologically safe simulation learning environment. It is known that failing to provide psychological safety can lead to feelings of incompetence and a lack of confidence with students. However, it is essential to understand what makes and maintains psychological safety in simulation from both student and facilitator's perspectives. In further understanding psychological safety, nursing educators can challenge students to think beyond that of task attainment and into the deeper realm of critical thinking and critical reflection.

OBJECTIVES

The aim of this study was to understand students' and facilitators perspectives of psychological safety in simulation.

METHODS

Participants in this qualitative interpretive description study were seven students and four faculty that were chosen using convenience sampling. The data was collected over a 2-week period where semi-structured interviews were used to collect the participants perspectives. Data analysis was continuous and iterative and used inductive analysis.

RESULTS

There were two student themes which focused on the student-facilitator interaction: 1) dynamic interaction, 2) student self-efficacy. The facilitators results showed two themes which focused on 1) simulation design and 2) trust.

CONCLUSION

Diverging thoughts are present between faculty and students in what constitutes psychological safety. In describing both the similarities and differences, we have a better understanding on how to create and maintain psychological safety thereby, providing students with the best learning experience possible.

A randomized, controlled, blinded evaluation of augmenting point-of-care ultrasound and remote telementored ultrasound in inexperienced operators

BACKGROUND

Handheld ultrasound devices present an opportunity for prehospital sonographic assessment of trauma, even in the hands of novice operators commonly found in military, maritime, or other austere environments. However, the reliability of such point-of-care ultrasound (POCUS) examinations by novices is rightly questioned. A common strategy being examined to mitigate this reliability gap is remote mentoring by an expert.

OBJECTIVES

To assess the feasibility of utilizing POCUS in the hands of novice military or civilian emergency medicine service (EMS) providers, with and without the use of telementoring. To assess the mitigating or exacerbating effect telementoring may have on operator stress.

METHODS

Thirty-seven inexperienced physicians and EMTs serving as first responders in military or civilian EMS were randomized to receive or not receive telementoring during three POCUS trials: live model, Simbionix trainer, and jugular phantom. Salivary cortisol was obtained before and after the trial. Heart rate variability monitoring was performed throughout the trial.

RESULTS

There were no significant differences in clinical performance between the two groups. Iatrogenic complications of jugular venous catheterization were reduced by 26% in the telementored group (P < 0.001). Salivary cortisol levels dropped by 39% (P < 0.001) in the telementored group. Heart rate variability data also suggested mitigation of stress.

CONCLUSIONS

Telementoring of POCUS tasks was not found to improve performance by novices, but findings suggest that it may mitigate caregiver stress.

Resuscitative endovascular balloon occlusion of the aorta in Canada: a context-specific position paper from the Canadian Collaborative for Urgent Care Surgery (CANUCS)

Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a well-described intervention for noncompressible torso hemorrhage. Several Canadian centres have included REBOA in their hemorrhagic shock protocols. However, REBOA has known complications and equipoise regarding its use persists. The Canadian Collaborative on Urgent Care Surgery (CANUCS) comprises surgeons who provide acute trauma care and leadership in Canada, with experience in REBOA implementation, use, education and research. Our goal is to provide evidence- and experience-based recommendations regarding institutional implementation of a REBOA program, including multidisciplinary educational programs, attention to device and care pathway logistics, and a robust quality assurance program. This will allow Canadian trauma centres to maximize patient benefits and minimize risks of this potentially life-saving technology.

Design and Validity Evidence for a Unique Endoscopy Simulator Using a Commercial Video Game

Background Procedural simulation enhances early endoscopy training. Multiple commercial simulators are available; however, their application is limited by cost and poor user compliance. First-person "shooter" (FPS) video games are popular. In this study, we aimed to show that a novel in-house designed colonoscope controller used to play an FPS video game shares similar constructs with real-life endoscopy. Methodology Participants completed the first three levels on an FPS video game, Portal (Valve Corporation, Bellevue, WA), first using a conventional controller and then the modified endoscope controller. A total of 12 expert endoscopists and 12 surgical residents with minimal endoscopy experience were evaluated based on completion time, button presses, and hand motion analyses. Results Experts outperformed novices for completion time (expert: 944 seconds; novice: 1,515 seconds; p = 0.006) and hand movements (expert: 1,263.1; novice: 2,052.6; p = 0.004) in using the novel colonoscope controller. There was no difference in button presses or total path length traveled. Furthermore, performance did not differ using conventional game controls. Conclusions Experts outperformed novices using the endoscope but not the conventional controller with respect to the economy of movement and completion time. This result confirms that our endoscope-controlled video game shares similar paradigms with real-life endoscopy and serves as a first step toward creating a more enjoyable and cheaper alternative to commercially available endoscopy simulators.

Strategies to improve communication in telementoring in acute care coordination: a scoping review

Background

Telementoring facilitates the coordination of advanced medical care in rural, remote or austere environments. Because the interpersonal element of telementoring has been relatively underexplored, we conducted a scoping review to identify strategies to improve communication in telementoring.

Methods

Two independent reviewers searched all English-language articles in MEDLINE and Scopus from 1964 to 2017, as well as reference lists of relevant articles to identify articles addressing telementored interactions between health care providers. Search results were gathered in June 2017 and updated in January 2018. Identified articles were categorized by theme.

Results

We identified 144 articles, of which 56 met our inclusion criteria. Forty-one articles focused on improving dispatcher-directed cardiopulmonary resuscitation (CPR). Major themes included the importance of language in identifying out-of-hospital cardiac arrest and how to provide instructions to enable administration of effective CPR. A standardized approach with scripted questions was associated with improved detection of out-of-hospital cardiac arrest, and a concise script was associated with improved CPR quality compared to no mentoring, unscripted mentoring or more complex instructions. Six articles focused on physician-physician consultation. Use of a handover tool that highlighted critical information outperformed an unstructured approach regarding transmission of vital information. Nine articles examined telementoring in trauma resuscitation. A common theme was the need to establish an understanding between mentor and provider regarding the limitations of the provider and his or her environment.

Conclusion

The available data suggest that standardization coupled with short, concise validated scripts could improve efficacy, safety and engagement. Improvements will require multidisciplinary input, practice and deliberate efforts to address barriers.

Teaching Crisis Resource Management Skills to Nurses Using Simulation

BACKGROUND

Education programs teaching crisis resource management (CRM) skills (problem solving, situational awareness, resource utilization, communication, and leadership) have been shown to positively affect learner competence in handling crisis events. As part of an education program, a high-fidelity simulation program was used as a learning intervention to teach these skills to practicing nurses.

METHOD

In this repeated-measures observational study, 11 RNs were evaluated at four time points, measuring the effect of an education program on observed performance of CRM skills. Performance was measured using the Ottawa Global Rating Scale and a checklist tool.

RESULTS

Statistically significant changes in mean scores occurred between times one and two, and nonstatistically significant improvement occurred in means overall.

CONCLUSION

This study adds evidence of the effectiveness of high-fidelity simulation education and highlights the need for further research. [J Contin Educ Nurs. 2020;51(6):257-266.].

Intravenous Immunoglobulins for Refractory Status Epilepticus: A Scoping Systematic Review of the Pediatric Literature

Our goal was to perform a scoping systematic review of the literature on the use of intravenous immunoglobulins (IVIGs) for refractory status epilepticus (RSE) in pediatric patients. Articles from MEDLINE, BIOSIS, EMBASE, Global Health, Healthstar, Scopus, Cochrane Library, the International Clinical Trials Registry Platform, ClinicalTrials.gov (inception to June 2016), reference lists of relevant articles, and gray literature were searched. The strength of evidence was adjudicated using both the Oxford and Grading of Recommendation Assessment Development and Education (GRADE) methodology by two independent reviewers. We identified 21 original articles. Eighty-seven pediatric patients were described as having received IVIG therapy for RSE. The mean age was 7.8 years (range: 2–17.5 years). Seizure response occurred in 14 of the 87 patients (16.1%), with 3 (3.4%) and 11 (12.6%) displaying partial and complete responses, respectively. Seventy-three of the 87 patients (83.9%) failed to display any seizure response to IVIG therapy. No complications related to IVIG therapy were recorded. The majority of patients had moderate to severe neurological deficits upon follow-up. Oxford level 4, GRADE D evidence exists to suggest little to no impact on seizure control in pediatric autoimmune RSE. Routine use of IVIG for pediatric RSE cannot be recommended at this time and should be considered experimental.

[Bone augmentation of the extremely atrophic anterior mandible, using allogeneic block grafts, via submental approach]

Edentulous patients with advanced resorption of the mandible (atrophic mandible) suffer major discomfort when using dentures. Furthermore, placing dental implants is impossible due to lack of sufficient bone volume. In the past, several methods of bone grafting to the anterior mandible have been proposed. Most of them were unpredictable in either the short or long-term. In 2002 a technique for bone grafting of the anterior mandible via a submental approach was published. A wide reflection of the soft tissue was followed by implant placement. Autogenous particulate posterior iliac crest bone graft was used. The presence of the implants did not allow for contraction of the soft tissue and bone resorption. The addition of bone volume to the chin improved the facial aesthetics of the patients due to a fuller appearance of the chin and tightening of the skin of the neck. The submental approach changes the spatial orientation of the surgeon and placement of implants in the correct location and angle become challenging. Placement of the implants too far buccally was a prosthetic problem. A major disadvantage of autogenous bone grafting is the necessity to operate a donor site. The increasing experience in use of allogenic bone grafts with resorbable collagen membranes, allowed us to modify the submental approach for bone grafting of the anterior atrophic mandible, avoiding a donor site surgery. We chose to perform the bone graft as a first stage surgery, in which, via a submental approach allogenic bone blocks were adapted and fixated to the anterior mandible with titanium screws, xenograft and resorbable collagen membranes were used. A few months (>4) were allowed for graft consolidation and then a second stage surgery was performed, via an intraoral approach dental implants were placed. In this way we avoided loss of orientation and had a familiar setting for implant location and angulation. Five patients with atrophic mandibles were treated using this surgical protocol. Based on cone beam CT imaging, average bone height in the anterior mandible prior to treatment was 5.52 mm. After bone graft, the average gain in bone height was 12.74 mm. No major post-operative complications were noted. After bone graft consolidation, 4 or 5 dental implants were placed, most of the implants used were longer than 11.5 mm. 22 implants were placed, out of which 21 integrated (95.5%). Some of the patients were rehabilitated with overdentures and locators and some with PFM bridges. All patients were followed up for more than a year and no implant failure was recorded. Bone grafting to the anterior mandible using allogenic blocks with collagen membranes via a submental approach with second stage implant placement seems to be a viable solution for rehabilitation of the atrophic mandible.

The Fundamentals of Laparoscopic Surgery and LapVR evaluation metrics may not correlate with operative performance in a novice cohort

BACKGROUND

Considerable resources have been invested in both low- and high-fidelity simulators in surgical training. The purpose of this study was to investigate if the Fundamentals of Laparoscopic Surgery (FLS, low-fidelity box trainer) and LapVR (high-fidelity virtual reality) training systems correlate with operative performance on the Global Operative Assessment of Laparoscopic Skills (GOALS) global rating scale using a porcine cholecystectomy model in a novice surgical group with minimal laparoscopic experience.

METHODS

Fourteen postgraduate year 1 surgical residents with minimal laparoscopic experience performed tasks from the FLS program and the LapVR simulator as well as a live porcine laparoscopic cholecystectomy. Performance was evaluated using standardized FLS metrics, automatic computer evaluations, and a validated global rating scale.

RESULTS

Overall, FLS score did not show an association with GOALS global rating scale score on the porcine cholecystectomy. None of the five LapVR task scores were significantly associated with GOALS score on the porcine cholecystectomy.

CONCLUSIONS

Neither the low-fidelity box trainer or the high-fidelity virtual simulator demonstrated significant correlation with GOALS operative scores. These findings offer caution against the use of these modalities for brief assessments of novice surgical trainees, especially for predictive or selection purposes.

51. Structured assessment format for evaluating operative reports (SAFE-OR) in general surgery

This study determined the construct validity, inter-rater reliability and internal consistency of a “Structured Assessment Format for Evaluating Operative Reports” (SAFE-OR) in general surgery. The assessment instrument was developed using consensus criteria set forth by the Canadian Association of General Surgeons. It includes a structured assessment and a global quality rating scale. Residents divided into novice and experienced groups viewed and dictated a video-taped laparoscopic sigmoid colectomy. Transcriptions were then graded by blinded, independent faculty evaluators using SAFE-OR. Twenty-one residents participated in the study. Mean structured assessment scores (out of 44) were significantly lower for novice versus experienced residents (23.3 ± 5.2 vs 34.1 ± 6.0, t=0.001). Mean global quality scores (out of 45) were similarly lower for novice residents (25.6 ± 4.7 vs 35.9 ± 7.6, t=0.006). Inter-class correlation coefficients were 0.98 (95% CI 0.96-0.99) for structured assessment and 0.93 (95% CI 0.83-0.97) for global quality scales. Cronbach’s alpha coefficients for internal consistency were 0.85 for structured assessment and 0.96 for global quality assessment scales. SAFE-OR demonstrates significant construct validity, excellent inter-rater reliability and high internal consistency. This tool will allow educators to objectively evaluate the quality of trainee operative reports and ultimately provide a mechanism for implementing, monitoring, and refining curriculum for operative dictation communication skills.

Adverse events experienced while transferring the critically ill patient from the emergency department to the intensive care unit

OBJECTIVES

To determine the incidence and nature of adverse events and delay to patient transfer from emergency department to intensive care unit (ICU) in a metropolitan tertiary hospital.

METHOD

A 6-month prospective observational study in conjunction with a retrospective chart audit on all emergency department patients admitted to ICU, including those admitted via theatre or after a computed tomography scan.

RESULTS

Equipment problems was the most common adverse event occurring in 9% of patient transfers (n = 290). Hypothermia events occurred in 7% of transfers, cardiovascular events in 6% of patient transfers, delays to transfer >20 min occurred in 38% of the prospectively audited cases, with 14% waiting >1 h. One patient was found to have an incorrect patient identification band during a preoperative check.

CONCLUSIONS

This study generally reported lower rates of adverse events than noted in previous studies involving critically ill transfers. The most significant finding was the application of an incorrect patient identification band and has prompted a review of practice. The establishment of benchmark indicators for adverse events and delays in transfer will be useful for future audits.
