Integration as innovation in healthcare systems.

Healthcare systems in Canada are under pressure and require change-the status quo is no longer fit for purpose, if it ever was. Innovation is often held up as a cure for what ails us, but shiny new things or novel technologies alone have not been enough. This article will explore the concepts of differentiation and integration as being important drivers in the evolution of living organisms, ecosystems, and complex human organizations. The implications of this deep pattern of systems change are essential to understanding the roles of specialization in medicine, and optionality in primary care. Specifically, overspecialization without attention to the principles of healthcare integration can lead to fragmentation of care and worse patient outcomes. Finally, this article will describe some practical examples of system integration as innovation in the form of better public health and care delivery connections, health homes, and community care coordination centres.

The impact of cognitive biases, mental models, and mindsets on leadership and change in the health system.

Understanding how cognitive biases, mental models, and mindsets impact leadership in health systems is essential. This article supports the notion of cognitive biases as flawed thinking or cognitive traps which negatively influence leadership. Mental models that do not fit with current evidence limit our ability to comprehend and respond to system issues. Resulting mindsets affect cognition, behaviour, and decision-making. Metacognition is critical. The wicked problems in today's complex health system require leaders and everyone involved to elevate their personal, organizational, and disciplinary perspectives to a systems level. Three examples of mental models/mindsets are reviewed. They do not change simply because we wish or will them to. The first step is being aware of what they are and how they impact our thinking and decision-making. Some tips for managing these traps are offered as examples of how to challenge our leadership approach in the health system.

The mental demands of leadership in complex adaptive systems.

After a decade of calls for healthcare transformation, there is a convergence of themes in our general orienting models. The core metaphor of health system as machine (with closed boundaries, linear functions, and controlled predictable outputs) has given way to health as ecosystem (with open boundaries, non-linear functions, multiple interdependencies, and no single locus of control over outcomes). Current developmental psychology theory suggests that people construct their reality, and interact with their world, based on the epistemology (or "action-logic" or "mindset") of their stage of development. Through this lens, the skills for leading large-scale change in our increasingly complex world require significant cognitive and interpersonal development. The concept of vertical development may be an underemphasized aspect of system change. This article will discuss a new set of leadership skills and frameworks that emerge in the nexus of complex adaptive systems and adult development theory.

Cognitive bias in health leaders.

Cognitive bias can be a serious impediment to rational decision-making by health leaders. We use a hypothetical case study to introduce some basic concepts of bias with examples of mitigation strategies. We argue that the effect of biases should be considered when making every significant administrative decision.

The challenge of cognitive science for medical diagnosis.

The historical tendency to view medicine as both an art and a science may have contributed to a disinclination among clinicians towards cognitive science. In particular, this has had an impact on the approach towards the diagnostic process which is a barometer of clinical decision-making behaviour and is increasingly seen as a yardstick of clinician calibration and performance. The process itself is more complicated and complex than was previously imagined, with multiple variables that are difficult to predict, are interactive, and show nonlinearity. They appear to characterise a complex adaptive system. Many aspects of the diagnostic process, including the psychophysics of signal detection and discrimination, ergonomics, probability theory, decision analysis, factor analysis, causal analysis and more recent developments in judgement and decision-making (JDM), especially including the domain of heuristics and cognitive and affective biases, appear fundamental to a good understanding of it. A preliminary analysis of factors such as manifestness of illness and others that may impede clinicians' awareness and understanding of these issues is proposed here. It seems essential that medical trainees be explicitly and systematically exposed to specific areas of cognitive science during the undergraduate curriculum, and learn to incorporate them into clinical reasoning and decision-making. Importantly, this understanding is needed for the development of cognitive bias mitigation and improved calibration of JDM in clinical practice.

Influence of a province-wide trauma system on motor vehicle collision process of trauma care and mortality: a 10-year follow-up evaluation.

BACKGROUND: Mature trauma systems have evolved to respond to major injury-related morbidity and mortality. Studies of mature trauma systems have demonstrated improved survival, especially among seriously injured patients. From 1995 to 1998, a province-wide trauma system was implemented in the province of Nova Scotia. We measured the proportion of admissions to a tertiary level trauma centre and the proportion of in-hospital deaths among patients with major injuries as a result of a motor vehicle collisions (MVCs) before and 10 years after provincial trauma systems implementation. METHODS: We identified major trauma patients aged 16 years and older using external cause of injury codes pertaining to MVCs from population-based hospital claims and vital statistics data. Individuals who were admitted to hospital or died because of an MVC in 1993-1994 (preimplementation), were compared with those who were admitted to hospital or died in 2003-2005 (postimplementation). RESULTS: Postimplementation, there was a 9% increase in the number of seriously injured individuals with primary admission to tertiary care. This increase was statistically significant even after we adjusted for age, head injury and municipality of residence (relative risk [RR] 1.09, 95% confidence interval [CI] 1.04-1.14). The probability of dying while in hospital in the postimplementation period decreased by 29% (adjusted RR 0.57, 95% CI 0.32-1.03), although this difference was not statistically significant. CONCLUSION: Individuals seriously injured in MVCs in Nova Scotia were more likely to be admitted to tertiary care after the implementation of a province-wide trauma system. There was a trend toward decreased mortality, but further research is warranted to confirm the survival benefit and delineate other contributing factors.

Emergency medicine airway leads: a rapid response distributed educational model for emergency department COVID-19 airway management.

With the first case of COVID-19 confirmed in Canada in early 2020, our country joined in the fight against a novel pathogen in a global pandemic. The stress of uncertainty and practice change was most apparent in the emergency department when it came to managing known or suspected COVID-19 patients requiring airway management. Recognizing the need for a coordinated approach, a province wide rapid response distributed model of continuing professional development for airway management was developed utilizing Airway Leads to help prepare front-line medical personnel providing airway management for these patients. Airway Leads worked with local physicians to deliver consistent, high quality airway education across the province during the initial surge of cases. Education included both in person and virtual sessions along with real time ongoing support through provincial guidelines, videos, and other documents. Physician reported "stress level" pre- and post-Airway Lead support declined from a median score of 9 to 7 (on a 10-point Likert Scale).

RéSUMé: Le premier cas de COVID-19 ayant été confirmé au Canada au début de 2020, notre pays s'est joint à la lutte contre un nouveau pathogène dans une pandémie mondiale. Le stress de l'incertitude et du changement de pratique était plus évident au service d'urgence lorsqu'il s'agissait de gérer les patients connus ou soupçonnés de la COVID-19 qui avaient besoin d'une prise en charge des voies respiratoires. Reconnaissant la nécessité d'une approche coordonnée, un modèle de développement professionnel continu distribué à l'échelle de la province pour la gestion des voies aériennes a été élaboré en utilisant les Airway Leads pour aider à préparer le personnel médical de première ligne qui assure la gestion des voies aériennes de ces patients. Airway Leads a travaillé avec les médecins locaux pour dispenser un enseignement cohérent et de haute qualité sur les voies aériennes dans toute la province lors de l'augmentation initiale du nombre de cas. L'éducation comprenait à la fois des sessions en personne et virtuelles ainsi qu'un soutien continu en temps réel par le biais de directives provinciales, de vidéos et d'autres documents. Le "niveau de stress" déclaré par le médecin avant et après l'intervention de Airway Lead a diminué, passant d'un score médian de 9 à 7 (sur une échelle de Likert de 10 points).

Air versus ground transport of the major trauma patient: a natural experiment.

OBJECTIVES: 1) To compare the outcomes of adult trauma patients transported to a level I trauma center by helicopter vs. ground ambulance. 2) To determine whether using a unique "natural experiment" design to obtain the ground comparison group will reduce potential confounders. METHODS: Outcomes in adult trauma patients transported to a tertiary care trauma center by air were compared with outcomes in a group of patients who were accepted by the online medical control physician for air transport, but whose air missions were aborted for aviation reasons (weather, maintenance, out on a mission); these patients were subsequently transported by ground ambulance instead. Outcomes were also analyzed for a third ground control group composed of all other adult trauma patients transported by ground during this time period. Data were collected by retrospective database review of trauma patients transferred between July 1, 1997, and June 30, 2003. Outcomes were measured by Trauma Injury Severity Score (TRISS) analysis. Z and W scores were calculated. RESULTS: Three hundred ninety-seven missions were flown by LifeFlight during the study period vs. 57 in the clinical accept-aviation abort ground transport group. The mean ages, gender distributions, mechanisms of injury, and Injury Severity Scores (ISSs) were similar in the two groups. Per 100 patients transported, 5.61 more lives were saved in the air group vs. the clinical accept-aviation abort ground transport group (Z = 3.37). As per TRISS analysis, this is relative to the expected mortality seen with a similar group in the Major Trauma Outcomes Study (MTOS). The Z score for the clinical accept-aviation abort ground transport group was 0.4. The 1,195 patients in the third all-other ground control group had a higher mean age, lower mean ISS, and worse outcomes according to TRISS analysis (W = -2.02). CONCLUSIONS: This unique natural experiment led to better matched air vs. ground cohorts for comparison. As per TRISS analysis, air transport of the adult major trauma patient is associated with significantly improved survival as compared with ground transport.

Early lessons from COVID-19 that may reduce future emergency department crowding.

The COVID-19 pandemic has produced significant changes in emergency medicine patient volumes, clinical practice, and has accelerated a number of systems-level developments. Many of these changes produced efficiencies in emergency care systems and contributed to a reduction in crowding and access block. In this paper, we explore these changes, analyse their risks and benefits and examine their sustainability for the future to the extent that they may combat crowding. We also examine the necessity of a system-wide approach in addressing ED crowding and access block.

Health human resources for emergency medicine: a framework for the future.

In June of 2016, the Collaborative Working Group (CWG) on the Future of Emergency Medicine presented its final report at the Canadian Association of Emergency Physicians (CAEP) annual meeting in Quebec City. The CWG report made a number of recommendations concerning physician Human Health Resource (HHR) shortfalls in emergency medicine, specific changes for both the Royal College of Physicians and Surgeons of Canada (FRCPC) and the College of Family Physicians of Canada (CCFP-EM) training programs, HHR needs in rural and remote hospitals, future collaboration of the CCFP-EM and FRCPC programs, and directions for future research. All recommendations were endorsed by CAEP, the Royal College of Physicians and Surgeons of Canada (RCPSC), and the College of Family Physicians of Canada (CFPC). The CWG report was published in CJEM and has served as a basis for ongoing discussion in the emergency medicine community in Canada. The CWG identified an estimated shortfall of 478 emergency physicians in Canada in 2016, rising to 1071 by 2020 and 1518 by 2025 assuming no expansion of EM residency training capacity. In 2017, the CAEP board struck a new committee, The Future of Emergency Medicine in Canada (FEMC), to advocate with appropriate stakeholders to implement the CWG recommendations and to continue with this important work. FEMC led a workshop at CAEP 2018 in Calgary to develop a regional approach to HHR advocacy, recognizing different realities in each province and region. There was wide representation at this workshop and a rich and passionate discussion among those present. This paper represents the output of the workshop and will guide subsequent deliberations by FEMC. FEMC has set the following three goals as we work toward the overarching purpose to improve timely access to high quality emergency care: (1) to define and describe categories of emergency departments (EDs) in Canada, (2) define the full time equivalents required by category of ED in Canada, and (3) recommend the ideal combination of training and certification for emergency physicians in Canada. A fourth goal supports the other three goals: (4) urge further consideration and implementation of the CWG-EM recommendations related to coordination and optimization of the current two training programs. We believe that goals 1 and 2 can largely be accomplished by the CAEP annual meeting in 2020, and goal 3 by the CAEP annual meeting in 2021. Goal 4 is ongoing with both the RCPSC and the CFPC. We urge the EM community across Canada to engage with our committee to support improved access and EM care for all Canadians.

Ponderal somatogram analysis of girth measurements by position in division III college football players.

Ponderal somatograms assessed body composition in four groups of Division III collegiate football players: offensive line (OL), defensive line (DL), offensive backs (OB), and defensive backs (DB). Ponderal somatograms evaluate body size and shape by converting muscular (shoulders, chest, biceps, forearm, thigh, and calf) and nonmuscular (abdomen, hips, knee, ankle, and wrist) girths into ponderal equivalent (PE) values. Anthropometric measurements, including stature, body mass, girths, and percent body fat by densitometry were collected in 82 players (22 OL, 12 DL, 20 OB, and 28 DB) during preseason camp. PE values were calculated for each girth as PE, kilograms = (girth, cm / k) x stature, decimeters, where k = k constant from Behnke's reference man. PE values were compared to body mass to indicate overdevelopment (PE > body mass) and underdevelopment (PE < body mass). OL was significantly heavier than DL (+15.6 kg), OB (+25.2 kg), and DB (+22.4 kg). OL percent fat was significantly greater than DL (+5.9%), OB (+9.0%), and DB (+9.3%). Similar differences occurred in girths and PE values by position. Muscular components were generally overdeveloped, with the greatest overdevelopment in the biceps (OL + 16.0 kg, DL + 19 kg, OB + 14.2 kg, and DB + 16.2 kg). Nonmuscular abdomen, hips, and knee were generally overdeveloped, with the greatest overdevelopment in the OL abdomen (+19.3 kg). Nonmuscular ankle and wrist were underdeveloped. Ponderal somatograms provide a relatively quick and simple method to translate girth measurements into ponderal equivalent values that seem to be position-specific among offensive and defensive linemen and backs. Somatograms provide an appraisal of body composition that helps coaches and athletes monitor the effectiveness of strength and conditioning programs.

Out-of-hospital continuous positive airway pressure ventilation versus usual care in acute respiratory failure: a randomized controlled trial.

STUDY OBJECTIVE: Continuous positive airway pressure ventilation (CPAP) in appropriately selected patients with acute respiratory failure has been shown to reduce the need for tracheal intubation in hospital. Despite several case series, the effectiveness of out-of-hospital CPAP has not been rigorously studied. We performed a prospective, randomized, nonblinded, controlled trial to determine whether patients in severe respiratory distress treated with CPAP in the out-of-hospital setting have lower overall tracheal intubation rates than those treated with usual care. METHODS: Out-of-hospital patients in severe respiratory distress, with failing respiratory efforts, were eligible for the study. The study was approved under exception to informed consent guidelines. Patients were randomized to receive either usual care, including conventional medications plus oxygen by facemask, bag-valve-mask ventilation, or tracheal intubation, or conventional medications plus out-of-hospital CPAP. The primary outcome was need for tracheal intubation during the out-of-hospital/hospital episode of care. Mortality and length of stay were secondary outcomes of interest. RESULTS: In total, 71 patients were enrolled into the study, with 1 patient in each group lost to follow-up after refusing full consent. There were no important differences in baseline physiologic parameters, out-of-hospital scene times, or emergency department diagnosis between groups. In the usual care group, 17 of 34 (50%) patients were intubated versus 7 of 35 (20%) in the CPAP group (unadjusted odds ratio [OR] 0.25; 95% confidence interval [CI] 0.09 to 0.73; adjusted OR 0.16; 95% CI 0.04 to 0.7; number needed to treat 3; 95% CI 2 to 12). Mortality was 12 of 34 (35.3%) in the usual care versus 5 of 35 (14.3%) in the CPAP group (unadjusted OR 0.3; 95% CI 0.09 to 0.99). CONCLUSION: Paramedics can be trained to use CPAP for patients in severe respiratory failure. There was an absolute reduction in tracheal intubation rate of 30% and an absolute reduction in mortality of 21% in appropriately selected out-of-hospital patients who received CPAP instead of usual care. Larger, multicenter studies are recommended to confirm this observed benefit seen in this relatively small trial.

State of the Evidence for Emergency Medical Services (EMS) Care: The Evolution and Current Methodology of the Prehospital Evidence-Based Practice (PEP) Program.

Background: Emergency medical services (EMS) leaders and clinicians need to incorporate evidence into safe and effective clinical practice. Access to high-quality evidence, and the time to synthesize it, can be barriers to evidence-based practice. The Prehospital Evidence-Based Practice (PEP) program is an online, freely accessible, repository of critically appraised evidence specific to EMS. This paper describes the evolution and current methodology of the PEP program. Methods|design: The purpose of PEP is to identify, catalog and critically appraise relevant studies. Following regular systematic searches, two trained appraisers critically appraise included studies and assign a score on three-point level of evidence (LOE) and direction of evidence (DOE) scales. Each clinical intervention is plotted on a 3 × 3 (LOE × DOE) evidence matrix, which provides a summary recommendation. Discussion: The PEP program is a unique knowledge translation tool, specific to EMS. End-users can easily identify which clinical interventions are, or are not, supported by evidence.

Awake fiberoptic intubation using an optical stylet in an anticipated difficult airway.

Numerous rigid indirect fiberoptic and video-based airway tools have been developed as potential alternatives to direct laryngoscopy for intubation. Compared with flexible fiberoptic bronchoscopes, these devices are less expensive and may be easier to use. The role of these rigid instruments in managing the difficult airway in the emergency department is yet to be defined. This article details the use of a rigid fiberoptic stylet to manage an anticipated difficult airway by using topical anesthetic without sedation.

Trauma management outcomes associated with nonsurgeon versus surgeon trauma team leaders.

STUDY OBJECTIVE: We compare the effectiveness of surgeon and nonsurgeon trauma team leaders. METHODS: This retrospective study was conducted using data from a Canadian trauma registry database. Data from April 1, 1998, to March 31, 2005, from blunt and penetrating trauma patients aged 16 years or older and with trauma team activation (and without major burns) were included. Patient age, sex, trauma team leader (surgeon or nonsurgeon), mechanism of injury, Injury Severity Score, survival to 3 hours and to discharge, length of stay in the hospital, and Trauma and Injury Severity Score (TRISS) z scores were tabulated. RESULTS: Data from 807 patients were included. Because of the limited number of penetrating trauma cases, analyses focused on blunt trauma. Surgeon and nonsurgeon trauma team leader groups did not differ on injury severity, age, or sex. No difference was noted in survival to discharge (nonsurgeon 84.8%-surgeon 81.8%=3%; 95% confidence interval [CI] -3.5% to 9.5%), survival to 3 hours (nonsurgeon 96.8%-surgeon 96%=0.8%; 95% CI -2.2% to 3.8%), length of stay (median 13 days for nonsurgeon and 12 days for surgeon groups), or difference between actual and predicted survival (TRISS z scores nonsurgeon 0.64; surgeon 0.99). No trend toward group differences on any outcome variable was observed in penetrating trauma cases. CONCLUSION: No differences were found in the outcome of trauma patients treated by nonsurgeon versus surgeon trauma team leaders. These findings support a more collaborative approach to resuscitative trauma management with involvement of nonsurgeons as trauma team leaders.

Procedural sedation and analgesia in a Canadian adult tertiary care emergency department: a case series.

OBJECTIVES: To examine the safety of emergency department (ED) procedural sedation and analgesia (PSA) and the patterns of use of pharmacologic agents at a Canadian adult teaching hospital. METHODS: Retrospective analysis of the PSA records of 979 patients, treated between Aug. 1, 2004, and July 31, 2005, with descriptive statistical analysis. This represents an inclusive consecutive case series of all PSAs performed during the study period. RESULTS: Hypotension (systolic blood pressure < or = 85 mm Hg) was documented during PSA in 13 of 979 patients (1.3%; 95% confidence interval [CI] 0.3%-2.3%), and desaturation (SaO2 < or = 90) in 14 of 979 (1.4%; Cl 0.1%-2.7%). No cases of aspiration, endotracheal intubation or death were recorded. The most common medication used was fentanyl (94.0% of cases), followed by propofol (61.2%), midazolam (42.5%) and then ketamine (2.7%). The most frequently used 2-medication combinations were propofol and fentanyl (P/F) followed by midazolam and fentanyl (M/F), used with similar frequencies 58.1% (569/979) and 41.0% (401/979) respectively. There was no significant difference in the incidence of hypotension or desaturation between the P/F and M/F treated groups. In these patients, 9.1% (90/979) of patients received more than 2 different drugs. CONCLUSIONS: Adverse events during ED PSA are rare and of doubtful clinical significance. Propofol/fentanyl and midazolam/fentanyl are used safely, and at similar frequencies for ED PSA in this tertiary hospital case series. The use of ketamine for adult PSA is unusual in our facility.
