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.

Prospective identification of patient care measures done as part of a prehospital quality assurance program.

An urban paramedic service in the northeast United States with direct medical command from three local hospitals.

One thousand eight paramedic reports from October 1992 through March 1993.

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.

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).

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.

Nationwide data were collected concerning serious, disabling injuries requiring hospitalization (SDIH) or deaths among urban emergency medical services (EMS) providers.

A mail survey of EMS systems was conducted among the 200 most populated U.S. cities.

Participants were training and operations officers of urban EMS systems.

Ninety forms (45%) were returned with 88 evaluable (44%). There were 81 SDIHs for a rate of one in 31,616 dispatches. No deaths were reported. Body parts most frequently injured were the hand (22%), head (19%), foot (16%), and eye (14%). Although 90% of fire-based EMS systems (fire-EMS) provided helmets, eye protection, safety shoes, and gloves, less than half (45%) of nonfire-EMS did so. Three (4%) SDIHs resulted from acts of violence.

Occupational injuries of EMS personnel are at a serious level. Fire-based EMS systems experienced a higher rate of hand SDIHs despite the provision of protective equipment. Few nonfire-EMS staff are provided with safety equipment, which may have resulted in a relatively high number of head and hand SDIHs. Fire-EMS medical directors need to take an active role in verifying that protective equipment is adequate and appropriate to allow the performance of field EMS duties without being too cumbersome. Medical directors of nonfire-EMS must be advocates for the provision of basic protective equipment aimed at mitigating SDIHs of EMS staff.

Although emergency medical services (EMS) liability litigation is a concern of many prehospital health care providers, there have been no studies of these legal cases nationwide and no local case studies since 1987.

A retrospective case series was obtained from a computerized database of trial court cases filed against EMS agencies nation-wide. All legal cases that met the inclusion criteria were included in the study sample. These cases must have involved either ambulance collisions (AC) or patient care (PC) incidents, and they must have been closed between 1987 and 1992.

There were 76 cases that met the inclusion criteria. Half of these cases involved an AC, and the other cases alleged negligence of a PC encounter. Thirty (78.9%) of the plaintiffs in the AC cases were other motorists, and 35 (92.1%) of the plaintiffs in the PC cases were EMS patients. Almost half of the cases named an individual (usually an emergency medical technician or paramedic) as a codefendant. Thirty-one (40.8%) of the cases were closed without any payment to the plaintiff. There were five cases with plaintiffs' awards or settlements greater than [US] $1 million. Most (71.0%) ofthe ACs occurred in an intersection or when one vehicle rear-ended another vehicle. The most common negligence allegations in the PC cases were arrival delay, inadequate assessment, inadequate treatment, patient transport delay, and no patient transport.

Risk management for EMS requires specific knowledge of the common sources of EMS liability litigation. This sample of recent legal cases provides the common allegations of negligence. Recommendations to decrease the legal risk of EMS agencies and prehospital providers are suggested.

This study attempted to determine the extent of training and emergency care knowledge of public school teachers in midwestern states. A secondary purpose was to assess the frequency of injury and illness in the school setting requiring the teacher to first respond.

A questionnaire and 14-item, scenario-based, emergency medical care test was developed and pretested. A discrimination index was used for validation of the instrument and a reliability coefficient of .82 was computed using the Kuder-Richardson Formula 20. A randomly recruited group of public school nurses from Arkansas, Kansas, and Missouri administered the instrument to 334 teachers who had no prior knowledge of the test. A random telephone survey of local school patrons also was completed to determine parental assumptions and expectations for emergency care and cardiopulmonary resuscitation (CPR) training in teachers.

One-third (112 teachers) had no specific training in first-aid and 40% never had been trained in CPR. However, most (87%) of the respondents strongly agreed that emergency care training should be required in teacher preparation programs. Eighteen percent of the teachers responded to more than 20 injured or ill students annually, and 17% reported that they had encountered at least one life-threatening emergency in a student during their career. The average score for all respondents on the emergency care test was 58% (X2 = 8.12±2.42). Those with prior first-aid training averaged 60.5% (X2 = 8.47±2.32). Significant deficiencies were noted for recognition and appropriate treatment of student emergencies involving basic life support (BLS) and airway interventions, diabetic emergencies, and treatment of profuse bleeding. Forty of the 50 (80%) parents surveyed assumed that all teachers were adequately trained in first-aid and CPR.

Public school teachers represent a potentially effective first-response component during disasters and isolated emergencies in the school environment. Overall, most of public school teachers in this study were deficient in both training and knowledge of emergency care and BLS modalities. Lack of effective, formal emergency care training in teacher preparation programs coupled with no continuing education requirement is a possible explanation of these results. Emergency medical services providers should seek opportunities to help with first-responder training and continuing education in their schools.

Emergency medical services vehicle collisions (EMVCs) associated with the use of warning “lights and siren” (L&S) are responsible for injuries and death to emergency medical services (EMS) personnel and patients. This study examines patient outcome when medical protocol directs L&S transport.

During four months, all EMS calls initiated as an emergency request for service and culminating in transport to an emergency department (ED) were included. Medical criteria determined emergent (L&S) versus non-emergent transport. Patients with worsened conditions, as reported by EMS providers, were reviewed.

Countywide suburban/rural EMS system.

Ninety-two percent (1,495 of 1,625) of patients were transported non-emergently. Thirteen (1%) of these were reported to have worsened during transport, and none of them suffered any worsened outcome related to the non-L&S transport.

This medical protocol directing the use of warning L&S during patient transport results in infrequent L&S transport. In this study, no adverse outcomes were found related to non-L&S transports.

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.

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.

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.

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).

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.

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.

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.

A classroom in a large, urban medical center.

Subjects were basic EMTs who volunteered to take part after the conclusion of a six-hour endotracheal intubation training course.

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.

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.

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.

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.

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.

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.

To determine the awareness of citizens and physicians concerning the capabilities of a rural emergency medical services (EMS) system.

Citizens and physicians are unaware of the capabilities of the EMS system.

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.

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).

This study indicates that both physicians and the lay public have little understanding of the capabilities of their EMS system.
