Many state and local emergency medical services (EMS) systems may wish to modify provider levels and their scope of practice to align their systems with the recommendations of the National Emergency Medical Services Education and Practice Blueprint. To determine any changes that may be needed in a typical EMS system, the knowledge and skills of EMS providers in one rural area of North Carolina were compared with the knowledge and skills recommended in the National Emergency Medical Services Education and Practice Blueprint.

A survey listing 175 items of patient care-oriented knowledge and skills described in the National Emergency Medical Services Education and Practice Blueprint was developed. EMS providers from five rural eastern North Carolina counties were asked to identify on the survey those items of knowledge and skills they believed they possessed. The skills and knowledge selected by the respondents at the five different North Carolina levels of certification were compared with the knowledge and skills listed for comparable provider levels delineated by the National Emergency Medical Services Education and Practice Blueprint. The proportions of the recommended skills reported to be possessed by the respondents were compared to determine which North Carolina certification levels best correlate with the Blueprint.

One hundred forty-five EMS providers completed the survey. The proportion of recommended skills and knowledge reported to be possessed by Emergency Medical Technicians (EMTs) ranked significantly lower than did the skills and knowledge reported to be possessed by respondents at other levels in five of the 10 Blueprint elements. The proportion of recommended skills and knowledge reported to be possessed by EMT-Defibrillator-level personnel ranked lower than did those reported to be possessed by respondents at other levels in seven of the 10 Blueprint elements. The proportion of recommended skills and knowledge reported to be possessed by EMT-Intermediates ranked lower than did those reported to be possessed by respondents at other levels in nine of the 10 Blueprint elements. The proportion of recommended skills and knowledge reported to be possessed by EMT-Advanced Intermediates ranked lower than were the skills and knowledge reported to be possessed by respondents at other levels in two of the 10 Blueprint elements. Finally, the proportion of recommended skills and knowledge reported to be possessed by EMT-Paramedics ranked lower than were those reported to be possessed by respondents at other levels in one of the 10 Blueprint elements.

In North Carolina, combining the EMT and EMT-Defibrillator levels and eliminating the EMT-Intermediate level would create three levels of certification, which would be more consistent with levels recommended by the Blueprint. The results of this study should be considered in any effort to revise the levels of EMS certification in North Carolina and in planning the training curricula for bridging those levels. Other states may require similar action to align with the National Emergency Medical Services Education and Practice Blueprint.

Rapid transport from scene to closest trauma center requires optimal use of public safety first responder (FR), basic life support (BLS), advanced life support (ALS), and transport resources (ground or air). In some parts of this regional emergency medical services (EMS) system, on-scene ALS requires contact with on-line medical command (OLMC) to obtain authorization for air medical helicopter (AMH) dispatch, because some EMS medical directors believe that this may decrease overutilization of AMH services.

The hypothesis of this study was that requiring prior OLMC for AMH dispatch prolongs mean time to a trauma center versus either FR or BLS request for AMH.

Computer mapping programs were used to model the most rapid driving time to the closest trauma center from 167 actual AMH responses to the scene of a motor vehicle accident. In an OLMC-ALS model, only OLMC-ALS can request an AMH. In a BLS model, BLS units arrive on the scene and the crew requests simultaneous dispatch of an ALS response and an AMH. In the FR model, on arrival at the scene, a FR requests simultaneous dispatch of a BLS unit, an ALS unit, and an AMH.

The OLMC-ALS model resulted in a longer mean value for time to trauma center by an AMH than did the computer model for all ground transport settings. The FR model yielded a shorter mean time for AMH compared with the mean values for time to trauma center for all settings. Differences in mean values for time in urban settings were small (ground: 42 minutes, air: 36 minutes), whereas those for the suburban (ground: 52 minutes, air: 41 minutes), and those for rural (ground: 69 minutes, air: 47 minutes) were significant clinically. For the BLS model, these differences persisted, but were significant clinically only in the rural setting (ground: 68 minutes, air: 53 minutes).

Optimal use of AMH requires balancing the need for early helicopter dispatch to fully exploit its speed advantage with the disadvantage of expensive overutilization. This computer model indicates that the best person to request AMH varies by venue: in urban settings, the OLMC physician should request AMH dispatch; in suburban venues, BLS should request AMH dispatch; and in rural venues, FRs should request AMH dispatch.

Many colleges and universities appear to exist in relative isolation from community-based emergency medical services (EMS) systems. In response, some have developed their own EMS systems.

To determine the extent of this phenomenon and to delineate the characteristics of these systems.

Questionnaires were mailed to 1,503 colleges/universities in the United States and Canada. The questionnaire asked whether the institution had an EMS system and included 19 questions about the characteristics of the system.

A total of 919 (61 %) responses were received. Of the institutions responding, 234 (25%) had an EMS system and 31 (3.4%) were considering starting a system. Characteristics of the systems were as follows: 1) Types of patients—the two most common call types were medical and trauma/surgical; 134 (57%) reported one-fourth of calls to be medical and 91 (39%) reported one-fourth of calls to be trauma/surgical. 2) Type of service—133 (57%) services transport patients; 195 (83%) respond only to the campus or other university property; the remainder also respond to the community; and 135 (58%) function all year. 3) Dispatch—178 (76%) are dispatched by the campus police, although most services are dispatched by several sources; 46 (20%) use 9-1-1. 4) Personnel—two systems (0.85%) exclusively employ paramedic; 141 systems (60%) have at least one emergency medical technician; the remainder use emergency care attendants and first-aid providers; 118 (50%) have medical directors, of these 76 (64 %) are student health physicians and 21 (18%) are community physicians. 5) Demographic Information—The majority of the campus-based EMS systems exist on small campuses in urban areas.

A significant number of colleges/universities have EMS systems and one-half transport patients. However, the level of training of the personnel and medical direction may be below the standard for the EMS systems in the communities in which these campus-based systems exist.

The capnometric demonstration of end-tidal carbon dioxide (CO2) is a reliable method of differentiating between a correct endotracheal tube position and an accidental misplacement of the tube into the esophagus. Recently, several CO2 detectors have been introduced for monitoring end-tidal CO2 in the “out-of-hospital” setting, where quantitative capnometry with capnography is not yet available.

These devices are not influenced by carbon monoxide (CO) present in lethal concentration.

A heated (37°C) 2.3 L reservoir bag filled one-third full with water (representing the stomach in esophageal misintubation) was machine ventilated (tidal volume: 450 ml; frequency: 16/min) with the following mixtures for three minutes each: 1) 95% O2, 5% CO; 2) 45% O2 5% CO, 50% N2O; and 3) 44% O2 5% CO, 50% N2O, 1% halothane. The presence of end-tidal CO2 was monitored with each of the following devices: 1) MiniCAP™ III CO2 Detector; 2) StatCAP™ CO2 Detector; 3) EasyCAP™ CO2 Detector; PediCAP™ CO2 Detector; and 5) Colibri™ CO2 Detector.

In none of the cases was the presence of CO2 signaled by the detector.

The presence of 5% CO does not interfere with infrared spectrometry detection (MiniCAP™ and StatCAP™) or chemical detection (EasyCAP™, PediCAP™, and Colibri™) of CO2. The devices can be used safely in patients with CO poisoning for monitoring of endotracheal tube position.

Although the efficacy of the administration of beta-adrenergic bronchodilators has been demonstrated, the best method available for the delivery of these drugs in the prehospital setting has not been defined. This paper compares the effects of administration of metaproterenol when administered by paramedics using either a metered-dose inhaler (MDI) or a hand-held nebulizer (HHN).

There is no difference in the effects produced in patients suffering from smooth bronchiolar muscle spasm by metaproterenol when delivered either by a standard metered-dose inhaler or with a hand-held nebulizer.

Consecutive prehospital patients complaining of difficulty breathing with clinical evidence of bronchospasm and with a history of asthma, chronic obstructive pulmonary disease, or emphysema who were not in extremis.

Prior to the administration of metaproterenol, a peak expiratory flow rate (PEFR) was obtained. This measurement was repeated five minutes following the conclusion of the administration of metaproterenol. Patients in Burbank, California, received the treatment using a standard metered-dose inhaler, and those in Madison, Wisconsin, received the drug using a hand-held nebulizer. Peak expiratory flow rates were compared using Student's t-tests with Bonferroni's correction. Statistical significance was set at p <0.05.

Data were collected from 36 consecutive patients by the paramedics of the Burbank Fire Department and from 32 consecutive patients by the paramedics of the Madison Fire Department. For the metered-dose inhaler group, the mean value for peak expiratory flow rate for the pre-treatment test was 95.4 ±88.1 1/min, and after treatment was 109.4 ±89.3 1/min (p <0.001). For the hand-held nebulizer group, the mean value for peak expiratory flow rate before the administration of the metaproterenol was 96.1 ±76.3 1/min and following the treatment was 149.1 ±92.9 1/min (p <0.001). The mean values for the differences between the control peak expiratory flow rate and the post-treatment peak expiratory flow rate for the metered-dose inhaler group was +14.0 ±27.4 1/min, and for the hand-held nebulizer group was +53.0 ±69.1 1/min (p <0.003).

In the prehospital setting the administration of metaproterenol using a hand-held nebulizer is more effective than delivering the drug using a metered-dose inhaler. The hand-held nebulizer is easier to use and delivers a higher dose of the drug than is convenient using the metered-dose inhaler.

The purpose of this study was to determine whether basic life support, prehospital emergency medical care in a rural area affects the hospital course of patients with respiratory distress.

Medical records for patients admitted from the emergency department with a discharge diagnosis related to respiratory disease were reviewed. Data collected included: 1) mode of arrival; 2) initial symptom; 3) vital signs; 4) prehospital interventions applied; 5) hospital days; 6) discharge status; and 7) principal diagnosis. Multiple logistic regression analysis was used to predict length of hospital stay.

Charts for 603 patients were reviewed. Complete data for all variables included in the logistic regression analysis were available for 471 patients (78.1%). Because 55 patients died, only 416 (69.0%) were included in the multiple regression analysis conducted to predict length of hospital stay. Logistic regression analysis demonstrated that patients who arrived by ambulance and older patients were more likely to die; patients with higher systolic blood pressures were more likely to survive. Only patient age predicted length of hospital stay, with older patients having longer stays.

Basic life support prehospital care in this rural emergency medical services system does not result in a lower mortality rate or a shorter hospital stay for a broad group of patients with respiratory distress who require hospital admission. Although this study is limited to a single population and a single emergency medical services system, it is one of only a few studies of outcome in basic life support systems.

To determine characteristics of continuing education programs for paramedics in large metropolitan areas, and to make recommendations for changes in the Chicago Emergency Medical Services (EMS) system.

A survey of 95 metropolitan areas from each state in the United States.

EMS medical directors, coordinators, and administrators.

The survey population included 56 respondents. Within this group, 23% were from areas of 1 million people or more, 61% in areas with populations of 100,000 to 1 million and 16% from areas populated by < 100,000 people. Several system types were represented in the survey. In the systems surveyed, 98% mandate didactic continuing education requirements. Clinical continuing education was required by 34% of the systems. Ten systems (18%) awarded continuing education hours for documented in-field experience. This method did not have a specific structure by the majority of users. Both written and skills testing were used by most EMS systems to evaluate paramedic competency. No statistically significant differences (p >0.05) could be found among population subgroups or EMS system types when evaluating the use of these various methods.

EMS systems primarily use didactic sessions to meet their continuing education requirements. Nearly half of the systems requiring clinical continuing education use in-field credit to fulfill these requirements. In-field credit systems are poorly developed to date. This mechanism may be an effective alternative to usual clinical experiences for paramedics and deserves further investigation.

Considerable attention is being addressed to injury prevention. This study addresses the acceptance of a home injury-prevention survey as an injury-prevention tool in rural communities.

The purpose of this study was to evaluate public acceptance of a home injury-prevention survey as a tool to educate and enlighten the public about home injuries.

All patients with home injuries who came to Wetzel County Hospital Emergency Department were asked if they would participate in a home injury-prevention survey. The study was conducted from 01 May to 01 July 1995. Paramedics were used as interviewers because of the closeness they enjoy with the community.

During the study period, 2,104 patients came to the emergency department of Wetzel County Hospital. Of these, 386 sought care because of an injury sustained in their homes. From this group, 23 (5.9%) patients agreed to participate in a home injury-prevention study; 363 (94.1%) refused.

A home injury-prevention survey alone does not seem to be an effective tool to aid in the reduction of home injuries, because it is not embraced by the general public.
