The relationship between paramedics' level of education and degree of commitment.

INTRODUCTION: Emergency medical services (EMS) personnel attrition is a serious concern. Two fundamental psychological constructs linked to attrition are organizational and occupational commitment. OBJECTIVE: To determine if there is a relationship between a paramedic's degree of occupational/organizational commitment and the following: (1) levels of education and (2) type of employment. METHODS: This was a cross-sectional study of paramedics in 6 states that require continued paramedic national registration. The data collection instrument consisted of demographic and occupational and organizational commitment sections. For level of education, the primary independent variable, each subject was placed into 1 of 3 groups: (1) certificate, (2) associate's or bachelor's degree in EMS (degree), and (3) paramedic certificate or degree with a non-EMS postbaccalaureate degree. Type of employment (fire based vs non-fire based) was also used as an independent variable. Organizational and occupational commitment was measured using validated scales for each. Analysis of variance was used for the comparisons between levels of each of the independent variables. A P < .05 was considered significant. RESULTS: For occupational commitment, the participants with certificate level of education had a significantly higher score (88.9) than did those with either the degree (83.6) or postbaccalaureate (80.9) level of education. There were no significant differences for total organizational commitment. There were also no overall differences in occupational and organizational commitment between fire- and non-fire-based employees. CONCLUSION: Paramedic occupational commitment shows a statistically significant decrease with increased level of education. Factors associated with commitment of more highly educated paramedics need to be explored.

Is online pediatric continuing education effective in a rural state?

OBJECTIVE: This prospective study was designed to evaluate the effectiveness of online pediatric education for prehospital emergency medical technicians (EMTs). METHODS: Online emergency medical services (EMS) continuing education modules, on various pediatric emergency topics, were developed for dissemination statewide. Pre- and posttest scores were compared by EMT level of training, rural versus urban location, and individual module performance. RESULTS: A total of 539 participants completed both the pre- and posttests. Of these, more than one-third (38.0%) reported Bernalillo County, the only urban county in the state, as the county in which they worked. Pretest scores ranged from 0 to 15 (mean = 8.5; 95% confidence interval [CI] = 8.2, 8.7), with a median of 8.0 and a mode of 8.0. Posttest scores were higher, ranging from 4 to 15 (mean = 11.6; 95% CI = 11.4, 11.7). For the posttest, the median score was 12.0 and the mode was 13.0. Urban and rural EMTs improved in posttests comparably. EMT-Basic participants' scores improved (mean change in score = 3.4, 95% CI = 3.1, 3.7) more than those of EMT-Intermediates (mean = 2.9, 95% CI = 2.5, 3.2) or EMT-Paramedics (mean = 2.7, 95% CI = 2.2, 3.3). CONCLUSIONS: 1) The New Mexico EMS for Children (EMSC) online pediatric continuing education program increased EMTs' cognitive knowledge; 2) rural EMTs accessed the training more than urban EMTs; and 3) although pre- and posttest results varied by EMT licensure level, improvements in scores also varied such that posttest scores were more similar than pretest scores.

Relationship of restraint use, patient injury, and assaults on EMS personnel.

OBJECTIVE: We hypothesized that the assaults on EMS personnel by patients requiring restraints can be correlated with demographic information, patient condition, and other scene information such as presence the of law enforcement. METHODS: The study was a one-year cross-sectional study of paramedic restraint use and assault on EMS personnel in an urban area. A data collection form was completed by EMS for each patient placed in restraints. Study outcome variable was "Assault on EMS personnel." Predictor variables included demographic and EMS call information, patient condition, law-enforcement related variables, and the paramedic's perception of the need for chemical restraints. To compare predictor and outcome variables, a multivariable model with odds ratios and 95% confidence intervals was used. RESULTS: The study included 271 restrained patients over a 12-month period from April 2002 to April 2003. Seventy-seven (28%) cases were positive for assaults on EMS personnel. Multivariable analysis including 8 variables, indicated the following 6 variables were associated with assault on EMS personnel: time of day between midnight and 6 am (OR = 4.4, 95% CI = 1.6-12.7); female patient (OR for males 0.6, 95% CI = 0.3-1.0); violent patient (OR = 10.1, 95%CI = 2.3-48.2); patient injured under supervision (OR = 3.9, 95% CI = 1.1-13.8); arrested patient (OR = 4.4, 95% CI = 1.1-18.5); and perceived need for chemical restraint (OR = 2.1, 95% CI = 1.2-3.9). CONCLUSION: Multiple factors are correlated with assaults on EMS personnel by patients requiring restraints. By specifically targeting patients exhibiting these factors, EMS providers can help prevent injury to themselves. Patients not exhibiting these factors may be less dangerous.

Subsequent suicide mortality among emergency department patients seen for suicidal behavior.

OBJECTIVES: To determine whether suicide mortality rates for a cohort of patients seen and subsequently discharged from the ED for a suicide-related complaint were higher than for ED comparison groups. METHODS: This was a nonconcurrent cohort study set at a university-affiliated urban ED and Level 1 trauma center. All ED patients 10 years and older, with at least one ED visit between February 1994 and November 2004, were eligible. ED visit characteristics defined the cohort exposure. Patients with visits for suicide attempt or ideation, self-harm, or overdose (exposed) were compared with patients without these visits (unexposed). Exposure classification was determined from billing diagnoses, E-codes (E950-E959), and free-text searching of the ED tracking system data for suicide, overdose, and spelling variants. Emergency department patient data were probabilistically linked to state mortality records. The principal outcome was suicide death. Suicide mortality rates were calculated by using person-year (py) analyses. Relative rates (RR) and 95% confidence intervals (95% CIs) were calculated from Cox proportional hazards models. RESULTS: Among the 218,304 patients, the average follow-up was 6.0 years; there were 408 suicide deaths (incidence rate [IR]: 31.2 per 100,000 py). Males (IR: 48.3) had a higher rate than females (IR: 13.5; RR: 3.6; 95% CI = 2.8 to 4.6). A single ED visit for overdose (RR: 5.7; 95% CI = 4.5 to 7.4), suicidal ideation (RR: 6.7; 95% CI = 5.0 to 9.1), or self-harm (RR: 5.8; 95% CI = 5.1 to 10.6) was strongly associated with increased suicide risk, relative to other patients. CONCLUSIONS: The suicide rate among these ED patients is higher than population-based estimates. Rates among patients with suicidal ideation, overdose, or self-harm are especially high, supporting policies that mandate psychiatric interventions in all cases.

Understanding suicide attempts among American Indian adolescents in New Mexico: modifiable factors related to risk and resiliency.

OBJECTIVE: To examine correlates of suicide attempts among American Indian adolescents living on reservations in New Mexico. DESIGN: Cross-sectional PARTICIPANTS: American Indian adolescents attending school in New Mexico, grades 6 to 12. MAIN OUTCOME MEASURES: Data from the Search Institute Profiles of Student Life Attitudes and Behaviors survey related to suicide attempts and student assets and risk behaviors. Hypothesized predictor variables derived from 39 survey questions were tested against one outcome variable relating to prior suicide attempts. RESULTS: Of 690 American Indian students included in the study, 24.2% indicated having attempted suicide one or more times in their lives. Salient assets included having neighbors who cared about them, adults who made them feel important, and having friends who did well in school. Notable risk factors were feeling depressed, drug and alcohol use, and having been the victim of violence. CONCLUSIONS: Adolescent suicide continues to be a major concern for American Indians. A focus on strengthening parent-child relationships and community support for families may increase resiliency among youth at risk.

The New Mexico school nurse and emergency medical services emergency preparedness course: program description and evaluation.

Illness and injuries are common among students and school staff. Therefore, school nurses must be prepared. In this study, a 16-hour scenario-based emergency preparedness course for school nurses was evaluated for its effectiveness. Effectiveness was measured by (a) traditional methods (written exams and confidence surveys) and (b) skills and performance evaluations in simulated emergencies called On-site Mock Emergency Scenarios. School nurses who completed the emergency preparedness course showed significant improvement in knowledge, confidence, and On-site Mock Emergency Scenarios scores that measured each nurse's ability to apply knowledge in simulated emergencies.

Characteristics of fire station walk-in patients.

OBJECTIVE: To characterize the use of fire stations for walk-in health care and compare utilization patterns of fire stations in lower-income areas with those in higher-income areas. METHODS: The study was a retrospective review of emergency medical services (EMS) medical forms of patients who presented directly to a fire station for medical care during a 12-month period. RESULTS: During the study period, there were a total of 56,600 EMS calls by the studied fire department, with 155 visits by persons presenting to 19 fire stations in the 12 zip code areas. Of these, 131 were eligible for inclusion in our study. Of the 131 visits, 76 of 131 (58%) occurred in zip codes where more than 20% of residents lived below poverty level. Patients presenting to the fire station for medical care were disproportionately male, 84 of 131 (64%), aged 31-50 years, 61 of 131 (47%). Leading chief complaints were abrasion/laceration/hematoma, 20 of 131 (15%), shortness of breath, 18 of 131 (14%), loss of consciousness/syncope/dizziness/weakness, 17 of 131 (13%), musculoskeletal pain, 17 of 131 (13%), and chest pain, 14 of 131 (11%). Suicide, assault, alcohol, or substance intoxication (SAAD) was associated with 47 of 131 (36%) visits. Following evaluation at the fire station, 97 of 131 (82%) were transported by EMS; few patients were transported by private vehicle (n = 11) or did not need transport (n = 12). CONCLUSIONS: In the authors' EMS system, the use of fire stations for walk-in health occurs disproportionately in areas of poverty. SAAD features are present in more than one third of the visits.

Prehospital administration of morphine for isolated extremity injuries: a change in protocol reduces time to medication.

OBJECTIVE: To evaluate the effect of a new protocol allowing paramedics to administer morphine without a physician order to patients with extremity trauma with respect to time of morphine administration, scene time, morphine amount and number of doses per patient, and proportion of patients receiving morphine. METHODS: Data were abstracted from transport forms for a ten-month period prior to the implementation of the new protocol and for nine months after implementation. Data elements included patient age and sex, date, time of EMS arrival on scene, amount and number of morphine doses, and total number of patients transported. RESULTS: Implementation of the new protocol was associated with a decrease in time between emergency medical services (EMS) arrival on scene and administration of the first dose of morphine from 18.8 to 16.7 minutes, a difference of 2.1 minutes [95% confidence interval (95%CI) 1.3, 2.9]. The proportion of patients receiving analgesia at the scene, rather than during transport, increased from 62.7% before the protocol change to 69.5% after, an increase of 6.8% (95% CI 2.7, 11.0). Transports before and after implementation of the new protocol did not differ with respect to patient sex, age, or chief complaint; number of morphine doses or total morphine administered per patient; or proportion of prehospital patients receiving morphine. CONCLUSIONS: A change in protocol that permits trained paramedics to administer morphine without physician approval reduces time to analgesia administration without influencing the amount of morphine delivered per patient or the rate of prehospital morphine use. Further study should measure the effect on base hospital physician interruptions and patient outcome.

Health status and intimate partner violence: a cross-sectional study.

STUDY OBJECTIVE: We identify health variables associated with a history of intimate partner violence (IPV) using self-reported and laboratory measures. METHODS: This study used a cross-sectional design. Participants were a randomized sample of English-speaking women between the ages of 18 and 50 years who presented to a large urban emergency department. Potential participants were screened in the ED for a history of physical abuse and coded as having experienced no IPV (No IPV), as having a recent history of IPV (occurring in the previous 12 months; IPVA), or as having a remote history (most recent occurrence >12 months ago; IPVHx). Participants were interviewed several days later in an outpatient setting regarding demographics, medical care use, and physical and mental health variables. Participants also received urine and blood tests and a pelvic examination. RESULTS: Self-reported health was poorest among women reporting IPVA and best among women reporting no IPVA. Women in the IPVA group differed from women with no IPV history with respect to cocaine use (odds ratio [OR] 4.8; 95% confidence interval [CI] 1.4 to 17.3), sexually transmitted diseases (OR 5.1; 95% CI 1.5 to 20.3), and nightmare frequency (OR 11.6; 95% CI 2.3 to 83.4). Women reporting IPVHx were more likely to report a history of sexually transmitted diseases than women with no IPV history (OR 4.1; 95% CI 1.6 to 11.4) and had more frequent nightmares (OR 5.0; 95% CI 1.3 to 24.9). Urine and blood tests identified only 2 variables (hemoglobin levels, mean corpuscular volume) that differed significantly between groups by IPV history; these differences were not clinically significant. CONCLUSION: Women with a recent history of IPV reported a poorer health status than women with no IPV history; laboratory testing detected few differences.
