Immersive Video Modeling Versus Traditional Video Modeling for Teaching Central Venous Catheter Insertion to Medical Residents.

Background  Central Venous Catheter (CVC) placement is a common critical care procedure. Simulated practice has been shown to reduce its iatrogenic complications. Video modeling (VM) is an instructional adjunct that improves the quality and success of CVC insertion. Immersive VM can improve recall and skill translation, but its role in teaching medical procedures is not established. Research question/hypothesis We hypothesized that, relative to traditional VM, immersive VM would decrease cognitive load and enhance ultrasound-guided CVC insertion skill acquisition. Methods Thirty-two resident physicians from four specialties were randomized into traditional (control) or immersive VM (intervention) groups for three CVC training sessions. Cognitive load was quantified via NASA Task Load Index (TLX). Mean (± standard deviations) values were compared using two-tailed t-tests. Skill acquisition was quantified by procedural time and the average 5-point [EM1] [TB2] entrustment score of three expert raters. Results Overall entrustment scores improved from the first (3.44±0.98) to the third (4.06±1.23; p<0.002) session but were not significantly different between the control and intervention groups. There were no significant differences between NASA TLX scores or procedural time. Conclusion We found no significant difference in entrustment, cognitive load, or procedural time. Immersive VM was not found to be superior to traditional VM for teaching CVC insertion.

Medical surveillance unit: patient characteristics, outcome, and quality of care in Saskatchewan, Canada.

OBJECTIVE: Intermediate care units provide a high level of care to complex patients and are becoming increasingly popular in North America. Despite the growing popularity of Intermediate care units, very little is known about them. This study explored a typical Intermediate care unit, identifying patient characteristics including demographics, comorbidities, length of stay, as well as primary and secondary diagnosis and mortality. RESULTS: A total of 200 patients chart were reviewed, of which, 102 were male, and 89 patients were younger than 65 years old. Diabetes, hypertension, and chronic obstructive pulmonary disease were common among patients with a prevalence of 33.5%, 56%, and 32.5%, respectively. Alcohol use disorder, asthma, liver disease and IV drug abuse were much more common in patients younger than 65 years. The average length of stay was 5.31 days regardless of age. Almost two-thirds of the patients in the Intermediate care unit were admitted directly from the emergency room. The mortality rate among the patients studied was 9.5%. The most common admitting diagnosis was respiratory diseases such as chronic obstructive pulmonary disease or Pneumonia (38.0%), followed by cardiac disorders which were predominantly arrhythmias and congestive heart failure (27.0%).

An Assessment of Handover Culture and Preferred Information in the Transitions of Care of Elderly Patients.

Introduction Transitions of care for elderly patients in long term care (LTC) to the emergency department (ED) is fraught with communication challenges. Information preferred during these transitions has not been agreed upon. We sought to understand our local handover culture and identify what information is preferred in the transitions of care of these patients. Methods We performed a cross-sectional electronic survey that was distributed to 1470 healthcare providers (HCPs) and 82 patient and family advocates (PFAs) in two Canadian cities. The HCP group consisted of physicians and nurses in ED and LTC settings as well as paramedics. The survey was open for a period of one month with formal reminders sent weekly. Results A total of 12.9% of HCPs and 26.8% of PFAs responded to the survey. Only 41.3% of HCP respondents were aware of existing handover protocols and 83.2% indicated a desire for a single page handover form. HCPs identified concerns over handover culture surrounding workplace inefficiencies and increased demands to their time. Several preferred items of information in the transitions of care for the institutionalized elderly patient were also identified across both HCP and PFA groups. Conclusions Our study identified a need for improved local handover culture in transitions of care for the institutionalized elderly patient. We also identified the preferred elements of information during bilateral communication between LTC and the ED. Our results will be used to design a patient-centred handover form for future use in this population.

Characterizing the Long-term Care and Community-dwelling Elderly Patients' Use of the Emergency Department.

Introduction Elderly patients, particularly those in long-term care (LTC), are a growing proportion of patients who present to the emergency department (ED). This population is medically complex, with high burdens on ED resources and patient flow. This study sought to characterize how elderly LTC and community-dwelling (CD) patients use ED services.  Materials and methods This was a retrospective cohort study that assessed approximately 200 senior (age>65) ED visits. These patients were either residing in LTC facilities or they were CD. All participants lived in the same, medium-sized Canadian city. Data indicating demographic information, acuity of presentation, and administrative parameters (such as disposition status or length of stay) were collected and analyzed. Results A few statistically significant differences between the populations were noted. This included mean age, which was 82.6 years in the LTC population and 77.3 for the CD group (p<0.001). There were 27 repeat visits among patients in the LTC group, compared to six from the CD patients (p<0.001). In the LTC population, 75 patients required transport from emergency medical services (EMS) compared to 41 from the control group (p<0.001). Conclusion LTC patients re-present to the ED and use EMS services more frequently than their CD counterparts. This difference indicates potential areas to target for future quality improvement work to help enhance care to this vulnerable population.

Can Multiple Object Tracking Predict Laparoscopic Surgical Skills?

OBJECTIVE: The purpose of this study was to examine the relationship between multiple object tracking (MOT) and simulated laparoscopic surgery skills. METHODS: A total of 29 second-year medical students were recruited for this study. The participants completed 3 rounds of a three-dimensional MOT and a simulated laparoscopic surgery task. Averages of the performance on the tasks were calculated. Descriptive variables (i.e., age, hours of sleep, caffeine, and video game use) were measured via questionnaires. Data were analyzed using hierarchical regression models with surgical performance as the outcome variable. Predictor variable was the multiple objects tracking score and the descriptive variables. RESULTS: The regression models revealed a significant prediction of simulated laparoscopic surgical skills by the multiple objects tracking score. In particular, 29% of the variance of time to completion and 28% of the average surgical arm movement were explained. In both regressions, the MOT score was the only significant predictor. CONCLUSION: This study demonstrates the potential implications of perceptual-cognitive training for future surgeons. Along with motor skill practice, MOT may aid to better prepare health care professionals for the complex cognitive demands of surgery.
