Emergency Medical Services Professionals' Attitudes About Community Paramedic Programs.

INTRODUCTION: The number of community paramedic (CP) programs has expanded to mitigate the impact of increased patient usage on emergency services. However, it has not been determined to what extent emergency medical services (EMS) professionals would be willing to participate in this model of care. With this project, we sought to evaluate the perceptions of EMS professionals toward the concept of a CP program. METHODS: We used a cross-sectional study method to evaluate the perceptions of participating EMS professionals with regard to their understanding of and willingness to participate in a CP program. Approximately 350 licensed EMS professionals currently working for an EMS service that provides coverage to four states (Missouri, Arkansas, Kansas, and Oklahoma) were invited to participate in an electronic survey regarding their perceptions toward a CP program. We analyzed interval data using the Mann-Whitney U test, Kruskal-Wallis one-way analysis of variance, and Pearson correlation as appropriate. Multivariate logistic regression was performed to examine the impact of participant characteristics on their willingness to perform CP duties. Statistical significance was established at p ≤ 0.05. RESULTS: Of the 350 EMS professionals receiving an invitation, 283 (81%) participated. Of those participants, 165 (70%) indicated that they understood what a CP program entails. One hundred thirty-five (58%) stated they were likely to attend additional education in order to become a CP, 152 (66%) were willing to perform CP duties, and 175 (75%) felt that their respective communities would be in favor of a local CP program. Using logistic regression with regard to willingness to perform CP duties, we found that females were more willing than males (OR = 4.65; p = 0.03) and that those participants without any perceived time on shift to commit to CP duties were less willing than those who believed their work shifts could accommodate additional duties (OR = 0.20; p < 0.001). CONCLUSION: The majority of EMS professionals in this study believe they understand CP programs and perceive that their communities want them to provide CP-level care. While fewer in number, most are willing to attend additional CP education and/or are willing to perform CP duties.

Airway management in the air medical setting.

BACKGROUND: Airway management is a key component of air medical care for seriously ill and injured patients. This meta-analysis of the prehospital airway management literature explored the pooled air-medical placement success rates for oral endotracheal intubation (OETI), including rapid sequence intubation (RSI) and drug-facilitated intubation (DFI), nasotracheal intubation (NTI), blind insertion airway devices (BIAD), and surgical cricothyrotomy (SCRIC). METHODS: We performed a systematic literature search for all English language articles reporting success rates for airway procedures performed in the prehospital setting. After identifying articles specific to the air-medical environment, pooled estimates of success rates for each airway technique were calculated using a random effects meta-analysis model. RESULTS: Thirty-six unique studies, encompassing 4,574 procedures, reported airway management success rates in the air medical environment. The pooled estimates (95% CI) for intervention success across all clinicians and patients were: OETI (without RSI/DFI): 86.4% (81.2%-90.3%); DFI: 95.1% (84.1%-98.6%); RSI: 96.7% (94.8%-97.9%); NTI: 76.1% (71.9%-79.9%); BIAD: 94.0% (85.8%-97.6%); and SCRIC: 90.8% (80.6%-95.9%). CONCLUSION: We provide pooled estimates for airway management procedural success rates in the air medical setting. These data can be used by program managers and medical directors in determining the most appropriate airway management procedures to incorporate into their services and for benchmarking in quality improvement activities.

Teaching emergency medical services management skills using a computer simulation exercise.

INTRODUCTION: Simulation exercises have long been used to teach management skills in business schools. However, this pedagogical approach has not been reported in emergency medical services (EMS) management education. We sought to develop, deploy, and evaluate a computerized simulation exercise for teaching EMS management skills. METHODS: Using historical data, a computer simulation model of a regional EMS system was developed. After validation, the simulation was used in an EMS management course. Using historical operational and financial data of the EMS system under study, students designed an EMS system and prepared a budget based on their design. The design of each group was entered into the model that simulated the performance of the EMS system. Students were evaluated on operational and financial performance of their system design and budget accuracy and then surveyed about their experiences with the exercise. RESULTS: The model accurately simulated the performance of the real-world EMS system on which it was based. The exercise helped students identify operational inefficiencies in their system designs and highlighted budget inaccuracies. Most students rated the exercise as moderately or very realistic in ambulance deployment scheduling, budgeting, personnel cost calculations, demand forecasting, system design, and revenue projections. All students indicated the exercise was helpful in gaining a top management perspective, and 89% stated the exercise was helpful in bridging the gap between theory and reality. CONCLUSION: Preliminary experience with a computer simulator to teach EMS management skills was well received by students in a baccalaureate paramedic program and seems to be a valuable teaching tool.

A meta-analysis of prehospital airway control techniques part II: alternative airway devices and cricothyrotomy success rates.

BACKGROUND: Airway management is a key component of prehospital care for seriously ill and injured patients. Oral endotracheal intubation (OETI) is the definitive airway of choice in most emergency medical services (EMS) systems. However, OETI may not be an approved skill for some clinicians or may prove problematic in certain patients because of anatomic abnormalities, trauma, or inadequate relaxation. In these situations alternative airways are frequently employed. However, the reported success rates for these devices vary widely, and established benchmarks are lacking. OBJECTIVE: We sought to determine pooled estimates of the success rates of alternative airway devices (AADs) and needle cricothyrotomy (NCRIC) and surgical cricothyrotomy (SCRIC) placement through a meta-analysis of the literature. METHODS: We performed a systematic literature search for all English-language articles reporting success rates for AADs, SCRIC, and NCRIC. Studies of field procedures performed by prehospital personnel from any nation were included. All titles were reviewed independently by two authors using prespecified inclusion criteria. Pooled estimates of success rates for each airway technique were calculated using a random-effects meta-analysis model. RESULTS: Of 2,005 prehospital airway titles identified, 35 unique studies were retained for analysis of AAD success rates, encompassing a total of 10,172 prehospital patients. The success rates for SCRIC and NCRIC were analyzed across an additional 21 studies totaling 512 patients. The pooled estimates (and 95% confidence intervals [CIs]) for intervention success across all clinicians and patients were as follows: esophageal obturator airway-esophageal gastric tube airway (EOA-EGTA) 92.6% (90.1%-94.5%); pharyngeotracheal lumen airway (PTLA) 82.1% (74.0%-88.0%); esophageal-tracheal Combitube (ETC) 85.4% (77.3%-91.0%); laryngeal mask airway (LMA) 87.4% (79.0%-92.8%); King Laryngeal Tube airway (King LT) 96.5% (71.2%-99.7%); NCRIC 65.8% (42.3%-83.59%); and SCRIC 90.5% (84.8%-94.2%). CONCLUSIONS: We provide pooled estimates for prehospital AAD, NCRIC, and SCRIC airway interventions. Of the AADs, the King LT demonstrated the highest insertion success rate (96.5%), although this estimate is based on limited data, and data regarding its ventilatory effectiveness are lacking; more data are available for the ETC and LMA. The ETC, LMA, and PTLA all had similar-but lower-success rates (82.1%-87.4%). NCRIC has a low rate of success (65.8%); SCRIC has a much higher success rate (90.5%) and should be considered the preferred percutaneous rescue airway.

A meta-analysis of prehospital airway control techniques part I: orotracheal and nasotracheal intubation success rates.

BACKGROUND: Airway management is a key component of prehospital care for seriously ill and injured patients. Although endotracheal intubation has been a commonly performed prehospital procedure for nearly three decades, the safety and efficacy profile of prehospital intubation has been challenged in the last decade. Reported intubation success rates vary widely, and established benchmarks are lacking. OBJECTIVE: We sought to determine pooled estimates for oral endotracheal intubation (OETI) and nasotracheal intubation (NTI) placement success rates through a meta-analysis of the literature. METHODS: We performed a systematic literature search for all English-language articles reporting placement success rates for prehospital intubation. Studies of field procedures performed by prehospital personnel from any nation were included. All titles were reviewed independently by two authors using prespecified inclusion criteria. Pooled estimates of success rates for each airway technique, including drug-facilitated intubation (DFI) and rapid-sequence intubation (RSI), were calculated using a random-effects model. Historical trends were evaluated using meta-regression. RESULTS: Of 2,005 identified titles reviewed, 117 studies addressed OETI and 23 addressed NTI, encompassing a total of 57,132 prehospital patients. There was substantial interrater reliability in the review process (kappa = 0.81). The pooled estimates (and 95% confidence intervals [CIs]) for intervention success for nonphysician clinicians were as follows: overall non-RSI/non-DFI OETI success rate: 86.3% (82.6%-89.4%); OETI for non-cardiac arrest patients: 69.8% (50.9%-83.8%); DFI 86.8% (80.2%-91.4%); and RSI 96.7% (94.7%-98.0%). For pediatric patients, the paramedic OETI success rate was 83.2% (55.2%-95.2%). The overall NTI success rate for nonphysician clinicians was 75.9% (65.9%-83.7%). The historical trend of OETI reflects a 0.49% decline in success rates per year. CONCLUSIONS: We provide pooled estimates of placement success rates for prehospital airway interventions. For some patient and clinician characteristics, OETI has relatively low success rates. For nonarrest patients, DFI and RSI appear to increase success rates. Across all clinicians, NTI has a low rate of success, raising questions about the safety and efficacy of this procedure.

Estimates of cost-effectiveness of prehospital continuous positive airway pressure in the management of acute pulmonary edema.

OBJECTIVE: To estimate the cost-effectiveness of continuous positive airway pressure (CPAP) in managing prehospital acute pulmonary edema in an urban EMS system. METHODS: Using estimates from published reports on prehospital and emergency department CPAP, a cost-effectiveness model of implementing CPAP in a typical urban EMS system was derived from the societal perspective as well as the perspective of the implementing EMS system. To assess the robustness of the model, a series of univariate and multivariate sensitivity analyses was performed on the input variables. RESULTS: The cost of consumables, equipment, and training yielded a total cost of $89 per CPAP application. The theoretical system would be expected to use CPAP 4 times per 1000 EMS patients and is expected to save 0.75 additional lives per 1000 EMS patients at a cost of $490 per life saved. CPAP is also expected to result in approximately one less intubation per 6 CPAP applications and reduce hospitalization costs by $4075 per year for each CPAP application. Through sensitivity analyses the model was verified to be robust across a wide range of input variable assumptions. CONCLUSION: Previous studies have demonstrated the clinical effectiveness of CPAP in the management of acute pulmonary edema. Through a theoretical analysis which modeled the costs and clinical benefits of implementing CPAP in an urban EMS system, prehospital CPAP appears to be a cost-effective treatment.
