Nontechnical skills (NTS) have been identified as critical competencies of surgeons in the OR, and regulatory bodies have mandated their integration in postgraduate surgical curricula. Strong evidence supporting the effectiveness of curricular NTS training, however, is lacking. Junior surgical residents were randomized to receive either conventional residency training or additional NTS training in a 2-month curriculum. Learning was assessed through a knowledge quiz and an attitudes survey. Nontechnical performance was evaluated by blinded assessment of standardized OR crisis simulations at baseline (BL) and posttraining (PT) using the Nontechnical Skills for Surgeons (NOTSS) and Objective Structured Assessment of Nontechnical Skills (OSANTS) rating systems. Results are reported as median (interquartile ranges). Of...

Most errors are nontechnical, stemming from ineffective team leadership, nonstandardized communication among team members, lack of global situational awareness, poor use of resources and inappropriate triage and prioritization. We developed an interprofessional, simulation-based trauma team training curriculum for Canadian surgical trainees. Here we discuss its piloting and evaluation.

Training surgeon-scientists can involve resource-intense and lengthy training programs, including Masters and PhD degrees. Despite high enrollment rates in such programs, limited data exist regarding their outcome. The aim of the study was to investigate the scientific productivity of general surgeons who completed Masters or PhD graduate training compared with those who completed clinical residency training only. A retrospective cohort study of graduates of general surgery residency was conducted over 2 decades. Data regarding graduation year, dedicated research training type, as well as publication volume, authorship role, and publication impact of surgeons during and after training, were analyzed. The study was conducted in 2 general surgery residency training programs in Canada (Unive...

Interprofessional communication between surgical nurses and surgeons, often through the use of pagers, is currently characterized by information gaps and interprofessional tensions, both sources of workflow interruption, potential medical error, impaired educational experience, and job satisfaction. This study aims to define current patterns of, and understand enablers and barriers to interprofessional communication in general surgery, in order to optimize the use of communication technologies, teamwork, provider satisfaction, and quality and safety of patient care. We will use a mixed-methods multiphasic approach. In phase 1, a quantitative and content analysis of alpha-numeric pages (ANP) received by general surgery residents will be conducted to develop a paging taxonomy. Frequency, timing (on-call vs regular duty hours), and interval between pages will be described using a 4-week sample of pages. Results will be compared between pages sent to junior and senior residents. Finally, using an inductive analysis, two independent assessors will classify ANP thematically. In Phase 2, a qualitative constructivist approach will explore stakeholders&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39; experiences with interprofessional communication, including paging, through interviews and shadowing of 40 residents and 40 nurses at two institutions. Finally, a survey will be developed, tested, and administered to all general surgery nurses and residents at the same two institutions, to evaluate their attitudes about the effectiveness and quality of interprofessional communication, and assess their satisfaction. Describing the profile of current pages is the first step towards identifying areas and root causes of IPC inefficiency. This study will identify key contextual barriers to surgical nurse-house staff communication, and existing interprofessional knowledge and practice gaps. Our findings will inform the design of a guideline and tailored intervention to improve IPC in order to ensure high quality patient care, optimal educational experience, and provider satisfaction.

We present an assessment of the course in this Canadian general surgery residency program. We compared trainees' pre-and postcourse self-efficacy scores and multiple choice question (MCQ) examination results, using paired t tests and resident (n = 24) and faculty (n = 7) course ratings made according to a 10-item, 5-point Likert scale. Faculty were previously trained as ATOM instructors. Mean pre-and postcourse self-efficacy scores were 68.9 (standard deviation [SD] 24.0) and 101.4 (SD 14.8), respectively (p < 0.001). Mean pre-and post-MCQ scores were 16.4 (SD 3.2) and 18.8 (SD 2.7), respectively (p = 0.006). On the Likert scale (1 = strongly disagree, 5 = strongly agree), all faculty and residents rated the following items as 4-5: objectives were met; knowledge, skills, clinical training, ...

Protocolized resuscitation with blood products to achieve high plasma:RBC ratio has been advocated to improve survival. Our objectives were to measure compliance to our institutional MTP, to identify quality assurance activities that could improve protocol compliance and to determine if protocol compliance was related to patient outcome. Methods: The investigators determined 13 compliance criteria based upon our institutional protocol. We measured compliance in 72 consecutive MTP activations between January 2010 and September 2011 at a Level I trauma centre. Data elements were retrospectively retrieved from blood bank, trauma registry and clinical records. Patients were stratified into three groups based on compliance level, and mortality differences were compared. Results: Average compliance for the cohort (n = 72) was 66%. The most common cause of noncompliance was failure to send a complete haemorrhage panel from the trauma bay (96%). Failure to monitoring blood work every 30 min occurred in 89% of cases. Delay in activation and deactivation occurred in 50% and 50% respectively. Non-compliance to protocol-based administration of blood products happened in 47%.

Although much has been learned about the pathogens and the leukocyte responses to these pathogens, we are only beginning to understand the role of the host in these pathologies. The endothelium is a dynamic participant in cellular and organ function rather than a static barrier as it was once believed.

There is general agreement that immediate management of cervical spine injuries is mandatory to prevent further neurologic injury. Nevertheless, disagreement exists as to the actual incidence of cervical spinal trauma in conjunction with various facial fracture patterns. The purpose of this study was to review the incidence of cervical spine injury associated with various types of facial fractures presenting to St. Michael&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;s Hospital Regional Trauma Center, Toronto, Ontario, Canada. The authors conducted a retrospective chart review of craniomaxillofacial fracture patients presenting to St. Michael&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;s Hospital from January 1, 1994, to December 31, 2003, inclusive. The data from this 10-year time span revealed a total of 124 patients with cervical spine injuries drawn from a cohort of 3356 patients with craniomaxillofacial fractures. The overall incidence of cervical spine injury was 3.69 percent. Of these patients, 928 had isolated upper third facial or skull fractures, whereas isolated middle third facial fractures were seen in 716 patients and isolated lower third facial fractures were present in 798 patients. Combined facial fracture patterns, involving two or more facial thirds, accounted for the greatest number of cervical spine injuries, occurring in 8.86 percent (n = 914). The relationship between cervical spinal injuries and craniomaxillofacial trauma has been better defined as it relates to a regional trauma registry. The implications as related to the trauma assessment, diagnosis, and treatment of these injuries are reviewed.

We set out to evaluate the effect of variable case ascertainment of dead on arrivals on external benchmarking of risk-adjusted mortality using a form of sensitivity analysis. We used data from the National Trauma Data Bank to look for indirect evidence of systematic differences in case ascertainment. We evaluated whether there was any relationship between fewer than expected early (&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; or = 24 hours) deaths and overall risk-adjusted mortality. Fewer than expected early deaths were estimated through the W statistic and through an adjusted ratio of early to late (E/L) deaths. E/L ratios were assessed due to the potential correlation between performance and absolute number of early deaths as assessed by the W statistic. We estimate that as many as 47% of all deaths might be missing due to problems with case ascertainment. Centers with unexpectedly few early deaths (W statistic) were consistently high performing centers with a lower than expected overall mortality. More importantly, there was no relationship between the E/L death ratio and overall risk-adjusted mortality. Variable case ascertainment of dead on arrivals does not affect the ability to assess performance. Given that our approach has several assumptions, it is critically important that external validation of trauma registries be performed. If centers are to be judged through the quality of their data, then it is incumbent to first assure that data quality meets expectations.

Although injury prevention efforts might be directed to reduce the frequency or severity of injury in rural environments, it is plausible that interventions directed to improve injury care in the rural settings might also play a significant role in reducing mortality. To test this hypothesis, we set out to examine the relationship between rurality and the setting in which patient death was most likely to occur. Methods: This is a population-based retrospective cohort study evaluating all trauma deaths occurring in the province of Ontario, Canada, over the interval 2002 to 2003. Patient cohorts were defined by their potential to access trauma center care using two different approaches, rurality and timely access to trauma center care. Results: There were 3,486 deaths over the study interval, yielding an overall injury mortality rate of 14.6 per 100,000 person-years. Overall, more than half of deaths occurred before reaching an emergency department (ED). Prehospital deaths were twice as likely in the most rural locations and in those with limited access to timely trauma center care. However, among patients surviving long enough to reach hospital, there was a threefold increase in the risk of ED death among those injured in a region with limited access to trauma center care. Conclusions: We demonstrate that a significant proportion of deaths occur in rural EDs. This study provides new insights into rural trauma deaths and suggests the potential value of targeted interventions at the policy and provider level to improve the delivery of preliminary trauma care in rural environments.

Most injuries are preventable and can often be attributed to poor choices. STUDY DESIGN: A mixed methods study involving 262 high school students was conducted to study the effect on knowledge and risk assessment after a day-long injury prevention program, and to develop a theoretic framework to better understand attitudes and beliefs that underlie commonly seen behaviors among young people.

The purpose of this review was to appraise and summarize the design, implementation, and efficacy of peer-reviewed, simulation-based CRM training programs for postgraduate trainees (residents). Two independent reviewers conducted a structured literature review, querying multiple medical and allied health databases from 1950 to May 2010 (MEDLINE, EMBASE, CINAHL, EBM, and PsycINFO). We included articles that (1) were written in English, (2) were published in peer-reviewed journals, (3) included residents, (4) contained a simulation component, and (5) included a team-based component. Peer-reviewed articles describing the implementation of CRM instruction were critically appraised using the Kirkpatrick framework for evaluating training programs. Fifteen studies involving a total of 404 residents met inclusion criteria; most studies reported high resident satisfaction for CRM training. In several CRM domains, residents demonstrated significant improvements after training, which did not decay over time. With regard to design, oral feedback may be equivalent to video feedback and single-day interventions may be as efficacious as multiple-day interventions for residents. No studies demonstrated a link between simulation-based CRM training and performance during real-life critical events. The findings support the utility of CRM programs for residents. A high degree of satisfaction and perceived value reflect robust resident engagement. The iteration of themes from our review provides the basis for the development of best practices in curricula design. A dearth of well-designed, randomized studies preclude the quantification of impact of simulation-based training in the clinical environment.
