Cardiac arrest survival is rare without prehospital return of spontaneous circulation.

BACKGROUND: Emergency medical services (EMS) are crucial in the management of out-of-hospital cardiac arrest (OHCA). Despite accepted termination-of-resuscitation criteria, many patients are transported to the hospital without achieving field return of spontaneous circulation (ROSC). OBJECTIVE: We examine field ROSC influence on OHCA survival to hospital discharge in two large urban EMS systems. METHODS: A retrospective analysis of prospectively collected data was conducted. Data collection is a component of San Antonio Fire Department's comprehensive quality assurance/quality improvement program and Cincinnati Fire Department's participation in the Cardiac Arrest Registry to Enhance Survival (CARES) project. Attempted resuscitations of medical OHCA and cardiac OHCA for San Antonio and Cincinnati, respectively, from 2008 to 2010 were analyzed by city and in aggregate. RESULTS: A total of 2,483 resuscitation attempts were evaluated. Age and gender distributions were similar between cities, but ethnic profiles differed. Cincinnati had 17% (p = 0.002) more patients with an initial shockable rhythm and was more likely to initiate transport before field ROSC. Overall survival to hospital discharge was 165 of 2,483 (6.6%). More than one-third (894 of 2,483, 36%) achieved field ROSC. Survival with field ROSC was 17.2% (154 of 894) and without field ROSC was 0.69% (11 of 1,589). Of the 11 survivors transported prior to field ROSC, nine received defibrillation by EMS. No asystolic patient survived to hospital discharge without field ROSC. CONCLUSION: Survival to hospital discharge after OHCA is rare without field ROSC. Resuscitation efforts should focus on achieving field ROSC. Transport should be reserved for patients with field ROSC or a shockable rhythm.

Improving Administration of Prehospital Corticosteroids for Pediatric Asthma.

Early administration of systemic corticosteroids for asthma exacerbations in children is associated with improved outcomes. Implementation of a new emergency medical services (EMS) protocol guiding the administration of systemic corticosteroids for pediatric patients with asthma exacerbations went into effect in January 2016 in Southwest Ohio. Our SMART aim was to increase the proportion of children receiving systemic prehospital corticosteroids for asthma exacerbations from 0% to 70% over 2 years. METHODS: Key drivers were derived and tested using multiple plan-do-study-act cycles. Interventions included community EMS outreach and education, improved clarity in the prehospital protocol language, distribution of pocket-sized educational cards, and ongoing individualized EMS agency feedback on protocol adherence. Eligible patients included children age 3-16 years, who were transported by EMS to the pediatric emergency department with diagnoses consistent with asthma exacerbation. Manual chart review assessed eligibility to receive prehospital corticosteroids. Statistical process control charts tracked adherence to corticosteroid recommendations. RESULTS: A total of 256 encounters met the criteria for receiving prehospital corticosteroids for pediatric asthma exacerbations between January 1, 2016, and April 30, 2019. Special cause variation was demonstrated following education at high-volume EMS stations, and the centerline shifted to 34%. This shift has been sustained for 28 months. CONCLUSION: Improvement methodology increased prehospital corticosteroid administration for pediatric asthma exacerbations, although we failed to achieve our aim of increasing use to 70%. Many barriers exist in pediatric prehospital protocol implementation, many of which can be improved with quality improvement tools.

Postal survey methodology to assess patient satisfaction in a suburban emergency medical services system: an observational study.

BACKGROUND: Patient satisfaction is of growing importance to providers of emergency medical services (EMS). Prior reports of patient satisfaction have frequently used resource-intensive telephone follow-up to assess satisfaction. We determine the feasibility of using a single mailing, anonymous postal survey methodology for collecting patient satisfaction data from a suburban EMS system. METHODS: Patients transported between January 2001 and December 2004 were mailed a brief satisfaction questionnaire. The questionnaire was printed on a pre-addressed, postage paid postcard and consisted of five questions that used a five-point Likert scale to assess satisfaction with EMS personnel and services provided. Three open-ended questions assessed concerns, the most important service provided, and methods for improving service. Survey response rate was the primary outcome of interest. The Chi-square test was used to compare rates between years. RESULTS: The survey required about 6 man hours and cost about $70 per month. Overall response rate was 32.0% (857/2764; 95CI 30.3% - 33.9%). During the first year, response rate was 42.6% (95CI 38.5% - 46.8%), but was significantly lower in subsequent years (29.0% in year 2, 30.8% in year 3, and 27.6% in year 4, p < 0.05). There were 847/851 respondents (99.5%) who were satisfied or very satisfied with their EMS experience. Three patients felt the service was adequate and one was very unsatisfied. Open-ended questions suggested that interpersonal communications were the single most important contributor to patient satisfaction. Patients also reported that response times and technical aspects of care were important to them. CONCLUSION: Postal surveys for assessing patient satisfaction following EMS transport can achieve comparable response rates to similar surveys in other health care settings. Response rates did not decline after the second year of patient surveys, suggesting some stability after the initial year. Interpersonal communication was determined to be the single most important contributor to patient satisfaction.

Evaluating an emergency medical services-initiated nontransport system.

OBJECTIVE: To evaluate both factors predicting nontransport and mortality rates in an emergency medical services system with a nontransport policy. METHODS: We reviewed data from 1,581 transported and nontransported patients from October 2001 to July 2003. Patients who refused transport against medical advice were excluded. Extracted data included demographics, run characteristics, chief complaint, and clinical impression. Transported and nontransported patients were compared using Mann-Whitney U or chi-square tests. Logistic regression identified factors predictive of nontransport. A Social Security Death Index search determined 30-day mortality. RESULTS: A total of 1,501 runs involving 1,059 patients were included. Median age was 60 years (range, 0-97 years). A total of 427 (40.4%) were male; 107 (10.2%) were nonwhite. Older patients were more likely to be transported (odds ratio, 1.03; confidence interval, 1.02-1.03). Race, frequency of calls, mutual aid, or time of day did not significantly influence probability of transport. Patients with cardiovascular, respiratory, and gastrointestinal complaints were more likely to be transported than those with other conditions (P < 0.005); patients with endocrine, trauma, and miscellaneous complaints were less likely to be transported (P < 0.003). Patients with renal, obstetrics/gynecology, and hema matology/oncology were complaints all transported. Mortality was 4.9% (confidence interval, 3.9%-6.2%) for transported patients and 1.0% for those not transported (confidence interval, 0.2%-3.7%). CONCLUSIONS: Age is a determinant when deciding on transporting patients. Patients with complaints with potentially higher acuity were transported most often. Only two nontransported patients died within 30 days, although it is unknown whether initial transport would have changed their mortality. Our data suggest that emergency medical services-initiated nontransport is influenced only by age and chief complaint and may not result in significant mortality.

Prehospital cardiac arrest in a paramedic first-responder system using the Utstein style.

OBJECTIVES: To describe the characteristics of patients found to have cardiac arrest and to evaluate the characteristics predictive of survival after cardiac arrest in a paramedic first-responder model. METHODS: All patients who suffered out-of-hospital cardiac arrest in the city of Reading, Ohio, from January 1998 to December 2003 were recorded in the Utstein style. The number and incidence rate of witnessed arrests, initial rhythms, rate of bystander cardiopulmonary resuscitation (CPR), and 30-day mortality rate were retrospectively collected. Demographics, time to hospital, and response times were evaluated as predictors of survival. RESULTS: Of those patients initially found to be in cardiac arrest, 14.3% were discharged alive. Witnessed arrests were more likely to result in live discharge of the patient. Whether bystander CPR was performed was not found to affect survival, nor was initial rhythm, although no patients initially found in asystole were discharged alive. No demographic characteristics or response times were predictive of survival. CONCLUSION: The rates of survival in this paramedic first-response system are favorable compared with basic emergency medical technician first-response systems. Further study using direct comparison methodology is warranted to confirm these findings.
