The objective of this study is to describe the Longitudinal Emergency Medical Technician (EMT) Attributes and Demographic Study (LEADS) design, instrument development, pilot testing, sampling procedures, and data collection methodology. Response rates are provided, along with results of follow-up surveys of non-responders (NRs) and a special survey of Emergency Medical Services (EMS) professionals who were not nationally certified.

Annual surveys from 1999 to 2008 were mailed out to a random, stratified sample of nationally registered EMT-Basics and Paramedics. Survey weights were developed to reflect each respondent’s probability of selection. A special survey of NRs was mailed out to individuals who did not respond to the annual survey to estimate the probable extent and direction of response bias. Individuals who indicated they were no longer in the profession were mailed a special exit survey to determine their reasons for leaving EMS.

Given the large number of comparisons between NR and regular (annual) survey respondents, it is not surprising that some statistically significant differences were found. In general, there were few differences. However, NRs tended to report higher annual EMS incomes, were younger, healthier, more physically fit, and were more likely to report that they were not practicing EMS. Comparisons of the nationally certified EMS professionals with EMS professionals who were not nationally certified indicated that nationally certified EMS providers were younger, had less EMS experiences, earned less, were more likely to be female and work for private EMS services, and less likely to work for fire-based services. These differences may reflect state and local policy and practice, since many states and local agencies do not require maintenance of national certification as a requirement to practice. When these differences were controlled for statistically, there were few systematic differences between non-nationally certified and nationally certified EMS professionals.

The LEADS study is the only national, randomized, and longitudinal data source for studying EMS professionals in the United States. Although not without flaws, this study remains an excellent source of information about EMS provider demographics, attributes, attitudes, workplace issues and concerns, and how the profession has changed from 1999 to 2008.

The objectives of this study were to assess longitudinal and cross-sectional changes in Emergency Medical Technician (EMT)-Basics and Paramedics: (1) demographics, (2) employment characteristics, and (3) initial Emergency Medical Services (EMS) education.

These data were collected between 1999 and 2008 employing survey techniques aimed at collecting valid data. A random, stratified sample was utilized to allow results to be generalizable to the nationally certified EMS population. Survey weights that were adjusted for each stratum’s response were estimated. Weighted percentages, averages for continuous variables, and 95% confidence intervals (CIs) were calculated. Significant changes over time were noted when the CIs did not overlap.

In all 10 years of data collection, the proportion of EMT-Paramedics who were male was greater than the proportion of EMT-Basics who were male. A substantial proportion of respondents performed EMS services for more than one agency: between 39.8% and 43.5% of EMT-Paramedics and 18.4% and 22.4% of EMT-Basic respondents reported this. The most common type of employer for both EMT-Basics and EMT-Paramedics was fire-based organizations. About one-third of EMT-Basics (32.3%-40.1%) and almost one-half of EMT-Paramedics (43.1%-45.3%) reported that these organizations were their main EMS employer. Rural areas (<25,000 residents) were the most common practice settings for EMT-Basics (52.1%-63.7%), while more EMT-Paramedics worked in urban settings (65.2%-77.7%).

This analysis serves as a useful baseline to measure future changes in the EMS profession. This study described the demographic and work-life characteristics of a cohort of nationally certified EMT-Basics and Paramedics over a 10-year period. This analysis also summarized initial EMS education changes over time.

The objective of this paper was to compare demographics, employment variables, satisfaction, and motivation for entering the field of Emergency Medical Services (EMS) between members of under-represented races/ethnicities and members of the majority group.

A cohort of nationally certified EMS professionals was followed for 10 years through annual surveys; however, race/ethnicity was only available for 9 years (2000-2008). Descriptive statistics and 95% confidence intervals (CIs) were calculated and significance was determined by lack of CI overlap.

From 2000 through 2008, the range of proportions of nationally certified EMS professionals by race/ethnicity was as follows: whites: 83.5%-86.0%, Hispanics: 4.2%-5.9%, and African-Americans: 2.5%-4.6%. There were no significant changes in the proportion of minority EMS professionals over the study period. Hispanics and African-Americans combined increased slightly from 6.7% of the population in 2000 to 9.9% in 2008. Likewise, the proportion of all under-represented races/ethnicities increased slightly from 2000 (14.0%) to 2008 (16.5%). Females were under-represented in all years. Nationally certified African-Americans were significantly more likely to be certified at the Emergency Medical Technician (EMT)-Basic level (compared with the EMT-Paramedic level) than whites in all but one survey year. The proportion of Hispanics registered at the EMT-Basic level was significantly higher than whites in three survey years. Accordingly, a larger proportion of whites were nationally registered at the EMT-Paramedic level than both African-Americans and Hispanics. A significantly larger proportion of African-Americans reported working in urban communities (population >25,000) compared with whites for nine of the 10 survey years. Similarly, a significantly larger proportion of Hispanics worked in urban communities compared with whites in 2002 and from 2005 to 2008. For satisfaction measures, there were no consistent differences between races/ethnicities. Among factors for entering EMS, the proportion of whites who reported having a friend or family member in the field was significantly higher than African-Americans in all years and significantly higher than Hispanics in four of the nine years.

The ethnic/racial diversity of the population of nationally certified EMS professionals is not representative of the population served and has not improved over the 2000-2008 period. Similar to other health care professions, Hispanics and African-Americans are under-represented in EMS compared with the US population. This study serves as a baseline to examine under-represented populations in EMS.

The purpose of this paper is to describe factors important for the recruitment and retention of Emergency Medical Technician (EMT)-Basics and EMT-Paramedics new to the Emergency Medical Services (EMS) field (defined as two years or less of EMS employment) through an analysis of 10 years of Longitudinal EMT Attributes and Demographic Study (LEADS) data.

Data were obtained from 10 years of LEADS surveys (1999-2008). Individuals new to the profession were identified through responses to a survey item. Their responses were analyzed using weights reflecting each individual’s probability of selection. Means, proportions, and 95% confidence intervals (CIs) were determined and used to identify statistically significant differences.

There were few changes in the demographic characteristics of new EMT-Basics and Paramedics across survey years. New EMT-Basics tended to be older and less likely to have a college degree than new EMT-Paramedics. More new EMT-Basics than EMT-Paramedics worked in rural areas and small towns and reported that they were working as a volunteer. There were differences between new EMT-Basics and EMT-Paramedics in several of the reasons for entering the profession and in facets of job satisfaction.

The findings provide guidance for recruiters, educators, employers, and governmental EMS policy organizations and will provide better insight into how to attract and retain new entrants to the field.

The objective of this paper is to identify factors associated with compensation for Emergency Medical Technician (EMT)-Basics and Paramedics and assess whether these associations have changed over the period 1999-2008.

Data obtained from the Longitudinal EMT Attributes and Demographic Study (LEADS) surveys, a mail survey of a random, stratified sample of nationally certified EMT-Basics and Paramedics, were analyzed. For the 1999-2003 period, analyses included all respondents providing Emergency Medical Services (EMS). With the addition of a survey in 2004 about volunteers, it was possible to exclude volunteers from these analyses.

Over 60% of EMT-Basics reported being either compensated or noncompensated volunteers in the 2004-2008 period. This was substantially and significantly greater than the proportion of EMT-Paramedic volunteers (<25%). The EMT-Paramedics earned significantly more than EMT-Basics, with differentials of $11,000-$18,000 over the course of the study. The major source of earnings disparity was type of organization: respondents employed by fire-based EMS agencies reported significantly higher earnings than other respondents, at both the EMT-Basic and EMT-Paramedic levels. Males also earned significantly more than females, with annual earnings differentials ranging from $7,000 to $15,000.

There are a number of factors associated with compensation disparities within the EMS profession. These include type of service (ie, fire-based vs. other types of agencies) and gender. The reasons for these disparities warrant further investigation.

The objectives were to assess changes in (1) health and physical fitness, (2) the prevalence of selected health problems, (3) risk behaviors, (4) ambulance safety issues, and (5) the preparedness of Emergency Medical Services (EMS) professionals. In addition, the incidence of patient-initiated violence directed toward EMS personnel and associated factors were assessed.

Data were obtained from a sample of nationally certified EMS professionals via annual questionnaires between 1999 and 2008. Stratification was based upon national certification level, self-reported race, and experience level. Weighted percentages, averages for continuous variables, and 95% confidence intervals (CIs) were calculated. Significant changes over time were noted by lack of CI overlap.

The proportion reporting “excellent” health declined significantly from 1999 (38.5%) to 2008 (32.2%). High rates of sleeping problems (20%-27%), back problems (20%-24%), and hearing problems (7%-10%) were reported as having occurred in the past year. These rates remained constant over time. As a result of sleepiness, 8.0% of nationally certified EMS professionals reported difficulty in driving an emergency vehicle for short distances and 17.5% reported difficulty in driving long distances. The proportion of daily tobacco smokers significantly declined from over one-third (35.3%) to about one-fifth (20.3%). The proportion of providers who had ever been involved in an ambulance crash increased slightly from 2004 (14.5%) to 2008 (15.8%). In 2000, the majority of EMS professionals reported that they and/or their partner had been assaulted by a patient. Finally, there was a significant decrease in the amount of training time devoted to the recognition of biological, chemical, and nuclear (BCN) threats, use of personal protective equipment (PPE), and treatment and management of patients exposed to BCN from an average from 8.4 hours in 2003 to 6.2 hours in 2008.

The overall health and physical fitness of EMS professionals as well as their health problems, risk behaviors, ambulance safety, and patient-initiated violence in the prehospital emergency setting are areas of concern for the nation’s emergency medical system. The prevalence of these problems and overall health and physical fitness has shown little or no improvement from 1999 to 2008.

The objective was to determine why Emergency Medical Technician (EMT)-Basics and Paramedics leave the Emergency Medical Services (EMS) workforce.

Data were collected through annual surveys of nationally registered EMT-Basics and Paramedics from 1999 to 2008. Survey items dealing with satisfaction with the EMS profession, likelihood of leaving the profession, and likelihood of leaving their EMS job were assessed for both EMT-Basics and Paramedics, along with reasons for leaving the profession. Individuals whose responses indicated that they were not working in EMS were mailed a special exit survey to determine the reasons for leaving EMS.

The likelihood of leaving the profession in the next year was low for both EMT-Basics and Paramedics. Although overall satisfaction levels with the profession were high, EMT-Basics were significantly more satisfied than Paramedics. The most important reasons for leaving the profession were choosing to pursue further education and moving to a new location. A desire for better pay and benefits was a significantly more important reason for EMT-Paramedics’ exit decisions than for EMT-Basics.

Given the anticipated increased demand for EMS professionals in the next decade, continued study of issues associated with retention is strongly recommended. Some specific recommendations and suggestions for promoting retention are provided.

The objective of this study was to assess the public’s experience, expectations, and perceptions related to Emergency Medical Services (EMS).

A population-based telephone interview of adults in the United States was conducted. The survey instrument consisted of 112 items. Demographic variables including age, race, political beliefs, and household income were collected. Data collection was performed by trained interviewers from Kent State University’s (Kent, Ohio USA)Social Research Laboratory. Descriptive statistics were calculated. Comparative analyses were conducted between those who used EMS at least once in the past five years and those who did not use EMS using χ2 and t tests.

A total of 2,443 phone calls were made and 1,348 individuals agreed to complete the survey (55.2%). There were 297 individuals who requested to drop out of the survey during the phone interview, leaving a total of 1,051 (43.0%) full responses. Participants ranged in age from 18 to 94 years with an average age of 57.5 years. Most were Caucasian or white (83.0%), married (62.8%), and held conservative political beliefs (54.8%). Three-fourths of all respondents believed that at least 40% of patients survive cardiac arrest when EMS services are received. Over half (56.7%) believed that Emergency Medical Technician (EMT)-Basics and EMT-Paramedics provide the same level of care. The estimated median hours of training required for EMT-Basics was 100 hours (IQR: 40-200 hours), while the vast majority of respondents estimated that EMT-Paramedics are required to take fewer than 1,000 clock hours of training (99.3%). The majority believed EMS professionals should be screened for illegal drug use (97.0%), criminal background (95.9%), mental health (95.2%), and physical fitness (91.3%). Over one-third (37.6%) had used EMS within the past five years. Of these individuals, over two-thirds (69.6%) rated their most recent experience as “excellent.” More of those who used EMS at least once in the past five years reported a willingness to consent to participate in EMS research compared with those who had not used EMS (69.9% vs. 61.4%, P=.005).

Most respondents who had used EMS services rated their experience as excellent. Nevertheless, expectations related to survival after cardiac arrest in the out-of-hospital setting were not realistic. Furthermore, much of the public was unaware of the differences in training hour requirements and level of care provided by EMT-Basics and EMT-Paramedics.
