ABSTRACT

AIM: High-quality cardiopulmonary resuscitation (CPR) may improve survival. The quality of CPR performed during pediatric out-of-hospital cardiac arrest (p-OHCA) is largely unknown. The main objective of this study was to describe the quality of CPR performed during p-OHCA resuscitation attempts. METHODS: Prospective observational multi-center cohort study of p-OHCA patients ≥ 1 and < 19 years of age registered in the Resuscitation Outcomes Consortium (ROC) Epistry database. The primary outcome was an a priori composite variable of compliance with American Heart Association (AHA) guidelines for both chest compression (CC) rate and CC fraction (CCF). Event compliance was defined as a case with 60% or more of its minute epochs compliant with AHA targets (rate 100-120 min(-1); depth ≥ 38 mm; and CCF ≥ 0.80). In a secondary analysis, multivariable logistic regression was used to evaluate the association between guideline compliance and return of spontaneous circulation (ROSC). RESULTS: Between December 2005 and December 2012, 2564 pediatric events were treated by EMS providers, 390 of which were included in the final cohort. Of these events, 22% achieved AHA compliance for both rate and CCF, 36% for rate alone, 53% for CCF alone, and 58% for depth alone. Over time, there was a significant increase in CCF (p < 0.001) and depth (p = 0.03). After controlling for potential confounders, there was no significant association between AHA guideline compliance and ROSC. CONCLUSIONS: In this multi-center study, we have established that there are opportunities for professional rescuers to improve prehospital CPR quality. Encouragingly, CCF and depth both increased significantly over time.

ABSTRACT

Hospitalization of nursing home residents can be futile as well as costly, and now evidence indicates that treating nursing home residents in place produces better outcomes for some conditions. We examined facility organizational characteristics that previous research showed are associated with potentially avoidable hospital transfers and with better care quality. Accordingly, we conducted a cross-sectional survey of nursing home directors of care in Vancouver Coastal Health, a large health region in British Columbia. The survey addressed staffing levels and organization, physician access, end-of-life care, and factors influencing facility-to-hospital transfers. Many of the modifiable organizational characteristics associated in the literature with potentially avoidable hospital transfers and better care quality are present in nursing homes in British Columbia. However, their presence is not universal, and some features, especially the organization of physician care and end-of-life planning and services, are particularly lacking.

ABSTRACT

OBJECTIVES: We sought to identify and characterize areas with high rates of major trauma events in 9 diverse cities and counties in the United States and Canada. METHODS: We analyzed a prospective, population-based cohort of injured individuals evaluated by 163 emergency medical service agencies transporting patients to 177 hospitals across the study sites between December 2005 and April 2007. Locations of injuries were geocoded, aggregated by census tract, assessed for geospatial clustering, and matched to sociodemographic measures. Negative binomial models were used to evaluate population measures. RESULTS: Emergency personnel evaluated 8786 major trauma patients, and data on 7326 of these patients were available for analysis. We identified 529 (13.7%) census tracts with a higher than expected incidence of major trauma events. In multivariable models, trauma events were associated with higher unemployment rates, larger percentages of non-White residents, smaller percentages of foreign-born residents, lower educational levels, smaller household sizes, younger age, and lower income levels. CONCLUSIONS: Major trauma events tend to cluster in census tracts with distinct population characteristics, suggesting that social and contextual factors may play a role in the occurrence of significant injury events.

ABSTRACT

OBJECTIVE: Timely reperfusion therapy for ST-elevation myocardial infarction (STEMI) is an important determinant of outcome, yet targets for time to treatment are frequently unmet in North America. Prehospital strategies can reduce time to reperfusion. We sought to determine the extent to which emergency medical services (EMS) use these strategies in Canada. METHODS: We carried out a cross-sectional survey in 2007 of ground EMS operators in British Columbia, Alberta, Ontario, Quebec and Nova Scotia. We focused on the use of 4 prehospital strategies: 1) 12-lead electrocardiogram (ECG), 2) routine expedited emergency department (ED) transfer of STEMI patients (from a referring ED to a percutaneous coronary intervention [PCI] centre), 3) prehospital bypass (ambulance bypass of local EDs to transport patients directly to PCI centres) and 4) prehospital fibrinolysis. RESULTS: Ninety-seven ambulance operators were surveyed, representing 15 681 paramedics serving 97% of the combined provincial populations. Of the operators surveyed, 68% (95% confidence interval [CI] 59%-77%) had ambulances equipped with 12-lead ECGs, ranging from 40% in Quebec to 100% in Alberta and Nova Scotia. Overall, 47% (95% CI 46%-48%) of paramedics were trained in ECG acquisition and 40% (95% CI 39%-41%) were trained in ECG interpretation. Only 18% (95% CI 10%-25%) of operators had prehospital bypass protocols; 45% (95% CI 35%-55%) had protocols for expedited ED transfer. Prehospital fibrinolysis was available only in Alberta. All EMS operators in British Columbia, Alberta and Nova Scotia used at least 1 of the 4 prehospital strategies, and one-third of operators in Ontario and Quebec used 0 of 4. In major urban centres, at least 1 of the 3 prehospital strategies 12-lead ECG acquisition, bypass or expedited transfer was used, but there was considerable variation within and across provinces. CONCLUSION: The implementation of widely recommended prehospital STEMI strategies varies substantially across the 5 provinces studied, and relatively simple existing technologies, such as prehospital ECGs, are underused in many regions. Substantial improvements in prehospital services and better integration with hospital-based care will be necessary in many regions of Canada if optimal times to reperfusion, and associated outcomes, are to be achieved.

ABSTRACT

BACKGROUND: Concerns have been raised about the enrollment of racial and ethnic minorities in research in the emergency setting when it is not possible to obtain informed consent. However, there is a paucity of data related to the validity of such claims. METHODS: Retrospective comparison of registry enrollment (4/1/2006-3/31/2007) and trial enrollment (4/1/2007-3/31/2008) from three sites in the Resuscitation Outcomes Consortium. Subjects compared met the following criteria: (1) shock, defined by blunt or penetrating force to the body with either systolic blood pressure (SBP) < or =70 mmHg or SBP 71-90 mmHg and heart rate > or =108 beats/min and/or (2) traumatic brain injury (TBI), defined by blunt force to the head with out-of-hospital Glasgow Coma Score < or =8. RESULTS: Overall, compared to a registry there were no differences in the percent of racial or ethnic groups enrolled in the clinical trial [odds ratio (OR) for Blacks versus Whites: 0.87, 95% confidence interval (CI) 0.65-1.16, p=.34; OR for Hispanics versus Whites 1.04; 95% CI 0.72-1.49, p=.85]. However, Blacks were less likely than Whites to be enrolled in the TBI cohort [OR 0.58 (0.34-0.97), p=.04]. CONCLUSIONS: Despite some discordance in subgroups, there was no overall difference in the racial and ethnic distribution of subjects enrolled in a multi-center clinical trial of severe trauma compared to a registry accounting for study entry criteria. These findings help address justice concerns about enrollment of racial and ethnic minorities in trauma research performed using an exception from informed consent under emergency circumstances.
