The perceived importance of paramedic skills and the emphasis they receive during EMS education programs

Out-of-hospital endotracheal intubation experience, confidence and confidence-associated factors among Northern Japanese emergency life-saving technicians: a population-based cross-sectional study

OBJECTIVE

Clinical procedural experience and confidence are both important when performing complex medical procedures. Since out-of-hospital endotracheal intubation (ETI) is a complex intervention, we sought to clarify clinical ETI experience among prehospital rescuers as well as their confidence in performing ETI and confidence-associated factors.

DESIGN

Population-based cross-sectional study conducted from January to September 2017.

SETTING

Northern Japan, including eight prefectures.

PARTICIPANTS

Emergency life-saving technicians (ELSTs) authorised to perform ETI.

OUTCOME MEASURES

Annual ETI exposure and confidence in performing ETI, according to a five-point Likert scale. To determine factors associated with ETI confidence, differences between confident ELSTs (those scoring 4 or 5 on the Likert scale) and non-confident ELSTs were evaluated.

RESULTS

Questionnaires were sent to 149 fire departments (FDs); 140 agreed to participate. Among the 2821 ELSTs working at responding FDs, 2620 returned the questionnaire (response rate, 92.9%); complete data sets were available for 2567 ELSTs (complete response rate, 91.0%). Of those 2567 respondents, 95.7% performed two or fewer ETI annually; 46.6% reported lack of confidence in performing ETI. Multivariable logistic regression analysis showed that years of clinical experience (adjusted OR (AOR) 1.09; 95% CI 1.05 to 1.13), annual ETI exposure (AOR 1.79; 95% CI 1.59 to 2.03) and the availability of ETI skill retention programmes including regular simulation training (AOR 1.31; 95% CI 1.02 to 1.68) and operating room training (AOR 1.44; 95% CI 1.14 to 1.83) were independently associated with confidence in performing ETI.

CONCLUSIONS

ETI is an uncommon event for most ELSTs, and nearly half of respondents did not have confidence in performing this procedure. Since confidence in ETI was independently associated with availability of regular simulation and operating room training, standardisation of ETI re-education that incorporates such methods may be useful for prehospital rescuers.

We need support! A Delphi study about desirable support during the first year in the emergency medical service

Background

New and inexperienced emergency medical service (EMS) professionals lack important experience. To prevent medical errors and improve retention there is an urgent need to identify ways to support new professionals during their first year in the EMS.

Methods

A purposeful sample and snowball technique was used and generated a panel of 32 registered nurses with 12–48 months of EMS experience. A Delphi technique in four rounds was used. Telephone interviews were undertaken in round one to identify what desirable support professionals new to the EMS desire during their first year. Content analysis of the transcribed interviews yielded items which were developed into a questionnaire. The experts graded each item in terms of perceived importance on a 5-graded likert scale. Consensus level was set at 75%. Items which reached consensus were removed from questionnaires used in subsequent rounds.

Results

Desirable support was categorized into eight areas: Support from practical skills exercises, support from theoretical knowledge, support from experiences based knowledge, theoretical support, support from an introduction period, support from colleagues and work environment, support from management and organization and other support. The experts agree on the level of importance on 64 of a total of 70 items regarding desirable support. One item was considered not important, graded 1 or 2, 63 items were considered important, graded 4 or 5.

Conclusion

Even with extensive formal competence the EMS context poses challenges where a wide variety of desirable forms of support is needed. Support structures should address both personal and professional levels and be EMS context oriented.

An exploration of the views of paramedics regarding airway management

BACKGROUND

Paramedics are a skilled group of clinicians with expertise in airway management. Our research group has completed a trial comparing supraglottic airway devices with tracheal intubation during out of hospital cardiac arrest. This is a contentious topic amongst paramedics in the United Kingdom (UK). We explored the customs and beliefs of UK paramedics in relation to airway management, and whether tracheal intubation contributes to and sustains paramedic professional identity.

METHODS

The study took place within South Western Ambulance Service NHS Foundation Trust. We used a qualitative approach, conducting interviews and focus groups with paramedics. The themes arising from interviews were discussed in focus groups, developing a deeper understanding and providing insight and recommendations for future research and policy. Purposive sampling accounted for differing training and for participation in the main trial. There were 17interviews and five focus groups with a further 17 participants. Data saturation was achieved.

RESULTS

Four domains were identified. Pride - The ability to use a life-saving skill in austere conditions. Utility - Different training routes and experience have led to different attitudes towards airway management. Inconsistent expectations - Paramedics felt that there were different perceptions of their abilities amongst hospital staff and the general public. Professionalization - Debate over airway management is not founded on good evidence.

CONCLUSION

We have demonstrated that UK paramedics have a wide range of views regarding airway management, and that these are based on evidence and experience rather than dogma. Airway management contributes to paramedics' professional identity, but is not reliant on this.

Populations at Risk for Intubation Nonattempt andFailure in the Prehospital Setting

OBJECTIVES

Pediatric cardiac arrest patients and adult traumatic arrest patients are perceived as more difficult to endotracheally intubate than adult cardiac arrest patients. The study hypothesis was that these populations were at higher risk of endotracheal intubation failure compared with adult cardiac arrest patients and that paramedics would more frequently defer attempts to intubate these patients.

METHODS

This was a retrospective, observational study analyzing oral endotracheal intubations on pediatric cardiac arrest, adult traumatic arrest, and adult cardiac arrest patients over 66 months. Homogeneity of intubation nonattempt and endotracheal intubation failure was studied with chi-square analysis. Relative risks (RRs) with 95% confidence intervals (CIs) were used to compare pediatric cardiac arrest with adult traumatic arrest with adult cardiac arrest nonattempt rates and endotracheal intubation failure rates.

RESULTS

2,669 oral endotracheal intubations were included. There was a significant difference in intubation nonattempts and intubation failure between the combined pediatric cardiac arrest and adult traumatic arrest groups and the adult cardiac arrest cohort (RR 7.24, 95% CI 5.73, 9.16 for nonattempt; RR = 2.33, 95% CI 1.93, 2.83 for intubation failure). Both groups individually showed significant risk for intubation nonattempt and endotracheal intubation failure compared with adult cardiac arrest, with the pediatric cohort at higher risk for failure and the adult traumatic arrest cohort at higher risk for nonattempt.

CONCLUSIONS

There was significant risk of intubation nonattempt and intubation failure in the pediatric cardiac arrest and adult traumatic arrest cohorts compared with the adult cardiac arrest population, with the pediatric cohort being at particularly high risk for intubation failure and the adult traumatic arrest cohort at higher risk for nonattempt.

Defining the Learning Curve for Paramedic Student Endotracheal Intubation

BACKGROUND

Proficiency in endotracheal intubation (ETI) is assumed to improve primarily with accumulated experience on live patients. While the National Standard Paramedic Curriculum recommends that paramedic students (PSs) perform at least five live ETIs, these training opportunities are limited.

OBJECTIVE

To evaluate the effects of cumulative live ETI experience, elapsed duration of training, and clinical setting on PS ETI proficiency.

METHODS

The authors used longitudinal, multicenter data from 60 paramedic training programs over a two-year period. The PSs reported outcomes (success/failure) for all live ETIs attempted in the operating room (OR), the emergency department (ED), the intensive care unit (ICU), and other hospital or prehospital settings. Fixed-effects logistic regression was used to model up to 30 consecutive ETI efforts by each PS, accounting for per-PS clustering. For each patient, the authors evaluated the association between ETI success and the PS's cumulative number of ETIs, adjusted for clinical setting, elapsed number of days from the first ETI encounter, and the interaction (cumulative ETIs x elapsed days). Predicted probability plots were constructed depicting the "learning curve" overall and for each clinical setting. Results. Between one and 74 ETIs (median 7; IQR 4-12) were performed by each of 802 PSs. Of 7,635 ETIs, 6,464 (87.4%) were successful. Stratified by clinical setting, 6,311 (82.7%) ETIs were performed in the OR, 271 (3.6%) in the ED, 64 (0.8%) in the ICU, 86 (1.1%) in other in-hospital settings, and 903 (11.8%) in the prehospital setting. For the 7,398 ETIs included in the multivariate analysis, cumulative number of ETI was associated with increased adjusted odds of ETI success (odds ratio 1.067 per ETI; 95% CI: 1.044-1.091). ETI learning curves were steepest for the ICU and prehospital settings but lower than for other clinical settings.

CONCLUSIONS

Paramedic student ETI success improves with accumulated live experience but appears to vary across different clinical settings. Strategies for PS airway education must consider the volume of live ETIs as well as the clinical settings used for ETI training.

Retention, learning by doing, and performance in emergency medical services

OBJECTIVES

To examine the strength of the volume-outcome relationship among paramedics, a group of providers that has not been previously studied in this context. By identifying the effects of individual learning on performance, we also assess the value of paramedics' retention. The prehospital emergency medical services (EMS) setting allows us to interpret any volume-outcome relationship as learning by doing, uncontaminated by reputation-based referrals because ambulance units are dispatched based on proximity.

DATA SOURCES

Incident-level EMS data spanning 1991 to 2005 from the Mississippi Emergency Medical Services Information System collected by the Mississippi Department of Health.

RESEARCH DESIGN

Using linear and quantile methods with and without provider fixed effects, we estimate the relationship between experience accumulation and performance using the universe of trauma incidents involving injured patients (including motor vehicle crashes, falls, stabbings, and shootings).

PRINCIPAL FINDINGS

We find that greater individual volume is robustly related to improved performance. In addition, we find that the benefit of learning operates through both recent and past experiences, accrues differentially across tenure groups, and operates on both mean performance and the upper quantiles of the performance distribution.

CONCLUSIONS

Persistent past and current volume effects suggest that policy and managerial implications in EMS should be directed at retention efforts to take advantage of individual learning by paramedics.

Clinical Experience and Practical Skills: Results from Mexico City's Paramedic Registry

Introduction: Trauma is a leading cause of death and disability in Mexico. Unintentional injuries, along with diabetes and heart disease, contribute to >35% of the country's total mortality. Effective and efficient prehospital care of the conditions may improve outcomes.

Objective: The objective of this paper was to determine if prehospital field experience (PFE) correlated with higher passing rates among candidates for the paramedic registry in Mexico City.

Methods: This was a retrospective, cohort study using data from the Voluntary Registry of Prehospital Care Professionals (VRPHP) in Mexico City.

Results: The mean value for candidate age was 30.6 years and mean value for the years of PFE was 6.8 years (CI = 9–13 years). Most of the applicants were male and almost 90% were basic emergency medical services providers. Sixty-five percent of the candidates were from private, non-profit organizations, 73% were volunteers, and 19% had obtained a university degree. More than 57% had ≥5 years of PFE, but the experience level did not correlate significantly with higher passing rates for the registry evaluation (χ2 = 1.66, p = 0.43).The results differed between the two years that the examination was offered (χ2 = 32.98, df = 1, p <0.001, γ = 0.54), regardless of gender, education, and years of experience.

Conclusions: Previous field experience showed no correlation with passing rates, although the correlations improved between examination periods. The results may be used to support appropriate implementation of future health policies for prehospital emergency services.

Procedural experience with out-of-hospital endotracheal intubation

OBJECTIVE

Out-of-hospital rescuers likely need regular clinical experience to perform endotracheal intubation (ETI) in a safe and effective manner. We sought to determine the frequency of ETI performed by individual out-of-hospital rescuers.

DESIGN

Analysis of an administrative database of all emergency medical services (EMS) patient care reports in Pennsylvania.

SETTING

Commonwealth of Pennsylvania from January 1 to December 31, 2003.

SUBJECTS

EMS advanced life support rescuers (paramedics, prehospital nurses, and EMS physicians) who reported at least one patient contact during the study period.

INTERVENTIONS

None.

MEASUREMENTS

We calculated individual rescuer ETI frequency and opportunity. We evaluated relationships between ETI frequency and the number of patient contacts. We also examined the relationship with practice setting (air medical vs. ground rescuers and urban vs. rural rescuers).

MAIN RESULTS

In 1,544,791 patient care reports, 11,484 ETIs were reported by 5,245 out-of-hospital rescuers. The median ETI frequency was one (interquartile range, 0-3; range, 0-23). Of 5,245 rescuers, >67% (3,551) performed two or fewer ETIs, and >39% (2,054) rescuers did not perform any ETIs. The median number of ETI opportunities was three (interquartile range, 0-6; range, 0-76). ETI frequency was associated with patient volume (Spearman's rho = 0.67) and was higher for air medical (p = .006) and urban (p < .0001) rescuers. ETI frequency was not associated with response (Spearman's rho = -0.01) or transport (Spearman's rho = -0.06) times.

CONCLUSIONS

Out-of-hospital ETI, an important and difficult resuscitation intervention, is an uncommon event for most rescuers.

Complaints against an EMS system

Complaints against Emergency Medical Services (EMS) agencies represent a concerning and potentially time-consuming problem for all involved in the delivery of prehospital emergency medical care. The objective of this study was to identify the source of complaints against an EMS system to help focus quality and performance improvement and customer service efforts. We conducted a retrospective review of complaints filed against a busy urban EMS agency over a 6-year period. All complaints were included, totaled by season and by year, and categorized by originator and nature of the complaint. A total of 286 complaints were registered during the 6-year period, with an average of 48 per year and 9.3 per 10,000 responses. The most common originators of complaints were patients (53%) followed by medical personnel (19%) and family members or friends (12%). Rude behavior accounted for 23% of the complaints registered, followed by technical skills (20%), transport problems (18%), and loss of belongings (13%). The identification of areas of dissatisfaction will allow focused quality and performance improvement programs directed at customer service and risk management.

Experience and mentoring requirements for competence in new/inexperienced paramedics

A paramedic may be unprepared to practice alone or with an inexperienced partner immediately following completion of training. Emergency medical services systems have not generally set standards to ensure that a newly-licensed paramedic is competent to practice alone. Many other trades and professions, including health care providers, require many hours of mentoring or apprenticeship prior to working in an unsupervised environment. This paper summarizes mentoring requirements for other clinical professions and reviews studies from the out-of-hospital and hospital literature that demonstrate a positive correlation between experience and outcome and/or competence. The author recommends specific benchmarking and supervision by a training officer or an experienced paramedic to ensure competence in new and inexperienced paramedics.

Training with video imaging improves the initial intubation success rates of paramedic trainees in an operating room setting

STUDY OBJECTIVE

Video imaging of intubation as seen by the laryngoscopist has not been a part of traditional instruction methods, and its potential impact on novice intubation success rates has not been evaluated.

METHODS

We prospectively tracked the success rates of novice intubators in paramedic classes who were required to watch a 26-minute instructional videotape made with a direct laryngoscopy imaging system (video group). We compared the prospectively obtained intubation success rate of the video group against retrospectively collected data from prior classes of paramedic students (traditional group) in the same training program. All classes received the same didactic airway instruction, same mannequin practice time, same paramedic textbook, and were trained in the same operating room with the same teaching staff.

RESULTS

The traditional group (n=113, total attempts 783) had a mean individual intubation success rate of 46.7% (95% confidence interval 42.2% to 51.3%). The video group (n=36, total attempts 102) had a mean individual intubation success rate of 88.1% (95% confidence interval 79.6% to 96.5%). The difference in mean intubation success rates between the 2 groups was 41.4% (95% confidence interval 31.1% to 50.7%, P <.0001). The 2 groups did not differ in respect to age, male sex, or level of education.

CONCLUSION

An instructional videotape made with the direct laryngoscopy video system significantly improved the initial success rates of novice intubators in an operating room setting.

Survey of nationally registered emergency medical services providers: pediatric education

STUDY OBJECTIVE

To survey emergency medical services (EMS) providers on a national level to determine and describe their perspective regarding their initial and continuing education (CE) needs in pediatrics.

METHODS

A 10-question survey was developed, pilot-tested, and sent to EMS providers as a part of their National Registry of Emergency Medical Technicians reregistration materials.

RESULTS

Surveys were completed by 18,218 EMS providers, a response rate of 67%. During a typical month, 60% of emergency medical technician-paramedics (EMT-Ps), 84% of EMT-intermediates (EMT-Is), and 87% of basic EMTs (EMT-Bs) care for 0 to 3 pediatric patients. CE was identified by all provider levels as the main source of their pediatric knowledge and skills. A state or national mandate for required CE in pediatrics was supported by 76% of surveyed providers. More than 70% of all providers responded they were comfortable to some degree with their own ability and their EMS system's ability when confronted with a critical pediatric call. Cost, availability, and travel distance were identified by all levels as the primary barriers to obtaining pediatric CE. All levels identified infants as the age of greatest concern if the provider was called to manage a critical case.

CONCLUSION

Surveyed practicing nationally registered EMS providers have infrequent contact with pediatric patients and have acquired most of their pediatric knowledge and skills from CE. In general, these providers are comfortable with their personal and their system's ability to care for children, but clearly support the need for required pediatric CE and identify the birth to 3-year age range as the priority for an educational focus. Cost, travel distance, and availability of pediatric CE are barriers that should be considered if pediatric CE is to be required of EMS providers.
