The Development of a Chest-Pain Protocol for Women Presenting to the Emergency Department.

Cardiovascular disease (CVD) is the leading cause of death in women worldwide, and of premature death in women in Canada. Despite improvements in cardiovascular care over the past 15-20 years, acute coronary syndrome (ACS) and CVD mortality continue to increase among women in Canada. Chest pain is a common symptom leading to emergency department visits for both men and women. However, women with ACS experience worse outcomes. compared with those of men, due to misdiagnosis or lack of diagnosis resulting in delayed care and underuse of guideline-directed medical therapies. CVD mortality rates are highest in Indigenous and racialized women and those with a disproportionately high number of adverse social determinants of health. CVD remains underrecognized, underdiagnosed, undertreated, and underresearched in women. Moreover, a lack of awareness of unique symptoms, clinical presentations, and sex-and-gender specific CVD risk factors, by healthcare professionals, leads to outcome disparities. In response to this knowledge gap, in acute recognition and management of chest-pain syndromes in women, the Canadian Women's Heart Health Alliance performed a needs assessment and review of CVD risk factors and ACS pathophysiology, through a sex and gender lens, and then developed a unique chest-pain assessment protocol utilizing modified dynamic programming algorithmic methodology. The resulting algorithmic protocol is presented. The output is intended as a quick reference algorithm that could be posted in emergency departments and other acute-care settings. Next steps include protocol implementation evaluation and impact assessment on CVD outcomes in women.

Les maladies cardiovasculaires (MCV) sont la principale cause de décès chez les femmes dans le monde et de décès prématuré chez les femmes au Canada. Malgré les progrès réalisés dans le domaine des soins cardiovasculaires au cours des 15 à 20 dernières années, les taux de syndrome coronarien aigu (SCA) et de mortalité due aux MCV continuent d'augmenter chez les femmes au Canada. La douleur thoracique est un symptôme fréquent qui pousse les hommes et les femmes à se rendre aux urgences. Toutefois, les femmes atteintes d'un SCA présentent de moins bons résultats cliniques que les hommes, en raison d'erreurs de diagnostic ou d'une absence de diagnostic causant des retards dans les soins prodigués et une sous-utilisation des traitements médicaux préconisés dans les lignes directrices. Les taux de mortalité liée aux MCV sont les plus élevés chez les femmes autochtones et les femmes racialisées ainsi que chez celles qui présentent un nombre particulièrement élevé de déterminants sociaux de la santé défavorables. Les MCV continuent d'être sous-estimées, sous-diagnostiquées et sous-traitées chez les femmes et ne sont pas suffisamment étudiées dans cette population. De plus, la méconnaissance par les professionnels de la santé des symptômes, des tableaux cliniques et des facteurs de risque de MCV selon le sexe et le genre entraînent des disparités dans les résultats cliniques. Pour combler ces lacunes dans les connaissances en matière de reconnaissance et de prise en charge des symptômes de douleur thoracique chez les femmes, l'Alliance canadienne de la santé cardiaque des femmes a réalisé une évaluation des besoins et un examen des facteurs de risque de MCV et de la physiopathologie du SCA en tenant compte des particularités liées au sexe et au genre, et a ensuite élaboré un protocole unique d'évaluation de la douleur thoracique faisant appel à une méthodologie algorithmique par programmation dynamique modifiée. Nous présentons le protocole algorithmique qui en est issu. Ce résultat se veut un algorithme de référence rapide pouvant être diffusé dans les services d'urgences et les autres services de soins de courte durée. Les prochaines étapes de notre travail seront d'évaluer la mise en œuvre du protocole et son incidence sur les issues cardiovasculaires chez les femmes.

Stress Testing the Resuscitation Room: Latent Threats to Patient Safety Identified During Interprofessional In Situ Simulation in a Canadian Academic Emergency Department.

OBJECTIVES: Emergency department (ED) resuscitation is a complex, high-stakes procedure where positive outcomes depend on effective interactions between the health care team, the patient, and the environment. Resuscitation teams work in dynamic environments and strive to ensure the timely delivery of necessary treatments, equipment, and skill sets when required. However, systemic failures in this environment cannot always be adequately anticipated, which exposes patients to opportunities for harm. METHODS: As part of a new interprofessional education and quality improvement initiative, this prospective, observational study sought to characterize latent safety threats (LSTs) identified during the delivery of in situ, simulated resuscitations in our ED. In situ simulation (ISS) sessions were delivered on a monthly basis in the EDs at each campus of a large tertiary care academic hospital system, during which a variety of scenarios were run with teams of ED health care professionals. LSTs were identified by simulation facilitators and participants during the case and debriefing and then grouped thematically for analysis. RESULTS: During the study period, 22 ISS sessions were delivered, involving 58 cases and reaching 383 ED health care professionals. 196 latent safety threats were identified through these sessions (mean = 3.4 LSTs per case) of which 110 were determined to be "actionable" at a system level. LSTs identified included system/environmental design flaws, equipment problems, failures in department processes, and knowledge/skill gaps. Corrective mechanisms were initiated in 85% of actionable cases. CONCLUSIONS: Effective quality improvement and continuing education programs are essential to translate these findings into more resilient patient care. ISS, beyond its role as a training tool for developing intrinsic and crisis resource management skills, can be effectively used to identify system issues in the ED that could expose critically ill patients to harm.

Adverse events in patients with return emergency department visits.

OBJECTIVES: This study describes the proportion of emergency department (ED) returns within 7 days due to adverse events, defined as adverse outcomes related to healthcare received. DESIGN: Prospective cohort study. SETTING: We used an electronically triggered adverse event surveillance system at a tertiary care ED from May to June 2010 to examine ED returns within 7 days of index visit. PARTICIPANTS: One of three trained nurses determined whether the visit was related to index emergency care. For such records, one of three trained emergency physicians conducted adverse event determinations. MAIN OUTCOME MEASURE: We determined adverse event type and severity and analysed the data with descriptive statistics, χ(2) tests and logistic regression. RESULTS: Of 13,495 index ED visits, 923 (6.8%) were followed by ED returns within 7 days. The median age of all patients was 47 years and 52.8% were women. After nursing review, 211 cases required physician review. Of these, 53 visits were adverse events (positive predictive value (PPV)=5.7%, 95% CI 4.4% to 7.4%) and 30 (56.6%) were preventable. Common adverse event types involved management, diagnostic or medication issues. We observed one potentially preventable death and 58.5% of adverse events resulting in transient disability. The PPV of a modified trigger with a cut-off of return within 72 h, resulting in admission was 11.9% (95% CI 6.8% to 18.9%). CONCLUSIONS: Our electronic trigger efficiently identified adverse events among 12% of patients with ED returns within 72 h, requiring hospital admission. Given the high degree of preventability of the identified adverse events, this trigger also holds promise as a performance measurement tool.
