To characterize the types of occupational exposures and injuries reported by emergency medical service (EMS) workers.
Methods:
A blinded review of accidents/exposures among EMS workers employed by a Baltimore County fire department was conducted. Medical records for 1992 were reviewed.
Results:
Two hundred and twenty-six reports were filed by EMS workers (n = 197) employed by a large, urban fire department in 1992. The most commonly reported injuries were sprains (23%), strains (20%), and exposure to blood and body fluids (15%). The body site most commonly injured was the back (20%) followed by the respiratory system (10%). Most incidents were treated at the employee health clinic, and 13% of the incidents resulted in a hospital visit. Fifteen percent of the injuries resulted in more than seven lost work days. Most incidents were caused by stretcher mishaps, especially during transport of heavy patients. Walkway impediments (e.g., icy steps, wet leaves, broken and uneven pathways) also played an important role in creating slipping and tripping hazards.
Conclusion:
These results suggest a variety of prevention strategies aimed at reducing accidents and exposures among EMS workers.
Complex, humanitarian emergencies, the result of civil strife and armed conflict affecting large populations at the brink of extinction, represent the most compelling of disaster relief challenges. They require the coordination of the United Nations agencies, the International Committee of the Red Cross, international nongovernmental relief organizations, and military forces. An increasing number of civilian and military health-care providers find themselves involved in the planning, coordination, and direct patient-care aspects of these emergencies, often without proper initiation and understanding of the unique nature of these disasters. This article provides a primer on the concept of complex, humanitarian emergencies and the contributions, characteristics, capabilities, and limitations of each major participant.
To determine the awareness of citizens and physicians concerning the capabilities of a rural emergency medical services (EMS) system.
Hypothesis:
Citizens and physicians are unaware of the capabilities of the EMS system.
Methods:
Residents were selected randomly from the local telephone directory and asked a series of structured questions about their EMS agency. A written survey was distributed to area physicians. Chi-square analysis was used to compare the proportion of respondents who knew the available interventions in their community with the proportion of those who did not. Statistical significance was inferred at p <0.01.
Results:
A total of 49% of the citizens were able to identify available skills, and 41.4% of the physicians were able to identify available skills. Physicians were less likely than were the citizens to be able to identify the skills performed by each provider (p <0.001).
Conclusion:
This study indicates that both physicians and the lay public have little understanding of the capabilities of their EMS system.
International emergency medical services (EMS) consultation requires many sensitivities to cross-cultural issues. Contemporary EMS models in developed countries have, by necessity, a systems framework. This study compares evolving EMS systems in the United States and China. It is concluded, that, no matter what the potential and cultural differences might be, a systems framework inherently will emerge in EMS development. As such, the EMS components recognized often will expose an evolving systems approach with more similarities than differences and can reveal strategies for improvement. Providing a developmental comparison process is a necessary first phase in analysis of a country's systems development or restructuring.
The purpose of this paper is to present approaches to foster critical thinking skills within the context of the current paramedic curriculum. It reviews some of the definitions and concepts of critical thinking from selected adult education and nursing literature in an attempt to formulate a workable definition as it applies to paramedics. From that definition, elements are identified and incorporated to form a teaching model for use in presenting the curriculum content. Some sample teaching strategies based on revised objectives of the airway/ventilation section also are included.
Advanced airway intervention techniques are being considered for use by basic emergency medical technicians (EMTs). It was hypothesized that basic EMTs would be able to discriminate reliably between intratracheal and esophageal endotracheal tube, placement in a mannequin model.
Design:
An airway mannequin with a closed chest cavity was intubated randomly either esophageally or tracheally, and the cuff was inflated. A stethoscope, bag ventilator, and laryngoscope were available next to the mannequin. Placement was assessed by auscultation or direct visualization at the discretion of the EMT. A blinded investigator graded the student.
Setting:
A classroom in a large, urban medical center.
Participants:
Subjects were basic EMTs who volunteered to take part after the conclusion of a six-hour endotracheal intubation training course.
Results:
Thirty-three subjects were tested. Seventeen of 18 (94%) tracheal intubations and 11 of 15 (73%) esophageal intubations were identified correctly. Only 72% of the students listened to the epigastrium, 81% listened to the lungs, and 85% attempted ventilation. The 10 students who visualized the cords discovered all five esophageal intubations. The 23 students who did not visualize the cords missed four and found six esophageal intubations.
Conclusion:
Basic EMTs had difficulty assessing endotracheal tube placement in a mannequin model. The 27% miss rate for identifying esophageal intubations suggests that basic EMTs will require additional training for safe field use of any airway that requires assessment of tube placement.
Background: In some emergency medical services (EMS) system designs, response time intervals are mandated with monetary penalties for noncompliance. These times are set with the goal of providing rapid, definitive patient care. The time interval of vehicle at scene-to-patient access (VSPA) has been measured, but its effect on response time interval compliance has not been determined.
Purpose:
To determine the effect of the VSPA interval on the mandated code 1 (<9 min) and code 2 (<13 min) response time interval compliance in an urban, public-utility model system.
Methods:
A prospective, observational study used independent third-party riders to collect the VSPA interval for emergency life-threatening (code 1) and emergency nonlife-threatening (code 2) calls. The VSPA interval was added to the 9-1-1 call-to-dispatch and vehicle dispatch-to-scene intervals to determine the total time interval from call received until paramedic access to the patient (9-1-1 call-to-patient access). Compliance with the man dated response time intervals was determined using the traditional time intervals (9-1-1 call-to-scene) plus the VSPA time intervals (9-1-1 call-to-patient access). Chi-square was used to determine statistical significance.
Results:
Of the 216 observed calls, 198 were matched to the traditional time intervals. Sixty three were code 1, and 135 were code 2. Of the code 1 calls, 90.5% were compliant using 9-1-1 call-to-scene intervals dropping to 63.5% using 9-1-1 call-to-patient access intervals (p<0.0005). Of the code 2 calls, 94.1% were compliant using 9-1-1 call-to-scene intervals. Compliance decreased to 83.7% using 9-1-1 call-to-patient access intervals (p = 0.012).
Conclusion:
The addition of the VSPA interval to the traditional time intervals impacts system response time compliance. Using 9-1-1 call-to-scene compliance as a basis for measuring system performance underestimates the time for the delivery of definitive care. This must be considered when response time interval compliances are defined.
The aim of this study was to compare the patient care measures provided by paramedics according to standing orders versus measures ordered by direct [on-line] medical command in order to determine the types and frequency of medical command orders.
Design:
Prospective identification of patient care measures done as part of a prehospital quality assurance program.
Setting:
An urban paramedic service in the northeast United States with direct medical command from three local hospitals.
Participants:
One thousand eight paramedic reports from October 1992 through March 1993.
Interventions:
All patient care interventions recorded as done by standing orders or by direct medical command orders. Errors in patient care were determined by the same criteria as in the prior two studies of the same system.
Results:
Direct medical command gave orders in 143/1,008 (14.2%) cases. Paramedics performed 2,453/2,624 (93.5%) of the total patient care interventions using standing orders. In 61 cases (6.1 %), medical command ordered a potentially beneficial intervention not specified by standing orders or not done by the paramedic. 21/171 (12.3%) command orders were for additional doses of epinephrine or atropine in cardiac arrest cases (where the initial doses had been given under standing orders), and 59/171 (34.5%) were for interventions already mandated or permitted by standing orders. The paramedic error rate was 0.6%, and the medical command error rate was 1.8% (unchanged form the prior study of the same standing-orders system).
Conclusion:
Direct medical command gave orders in 14% of cases in this standing-orders system, but 35% of command orders only reiterated the standing orders. More selective and reduced uses of on-line command could be done in this system with no change in the types or numbers of patient care interventions performed.
Patients with acute, intracranial bleeding (ICB), particularly from intracranial aneurysms, are believed to be at high risk for rebleeding or neurologic deterioration if subjected to noise, motion, or stress, but are transported by helicopter with increasing frequency. This study was undertaken to examine the characteristics, safety, and outcomes of air transport for patients with acute subarachnoid hemorrhage (SAH) or other forms of acute ICB in an air medical system.
Methods:
Charts of all patients with spontaneous, acute ICB who were transported by air from 1986 through 1989 were reviewed. Age, gender, time of transport, transport management measures, pre- and post-transport Glasgow Coma Scale (GCS) score, intensive care unit (ICU) and hospital days, operations, and mortality were compiled for all patients and analyzed.
Results:
Eighty-seven patients ranging in age from 2 to 83 years (mean: 47.5 ±18.5 years) met entry criteria. The source of bleeding was cerebral aneurysm in 37 patients; intraparenchymal hemorrhage in 29; an unidentified vascular source in 11; and arteriovenous malformation (AVM) in 10. Mean GCS score measured in 69 patients before and after transport was 10.5 ±4.5 Glasgow Coma Scale score did not change during transport in 61 patients (88%), improved in three (4%), and deteriorated in five (7%). Fifty-nine patients (69%) underwent operations, 36 (41%) within 24 hours of arrival. Mean ICU stay was 14 days (95% CI: 12–15); mean hospital stay was 36 days (95% CI: 27–45 days). Overall mortality was 25% (95% CI: 16–34 days). A GCS score of 3 to 8 at time of transport was associated with both increased hospital length of stay and higher mortality. Patients transported within eight hours of symptom onset had lower GCS scores, but out-come measures were not significantly different from those transported later.
Conclusion:
Emergency air medical transfer of patients with acute ICB for definitive neurosurgical care appears to be both safe and effective, and facilitates early definitive diagnosis and operative intervention.
