Clin Exp Emerg Med 2023; 10:287-295. [PMID: 36796782 PMCID: PMC10579723 DOI: 10.15441/ceem.22.389] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2022] [Revised: 01/09/2023] [Accepted: 01/31/2023] [Indexed: 02/18/2023] Open
Abstract
OBJECTIVE Burnout among emergency medical technicians is a serious problem affecting delivery of quality emergency medical services. Although the repetitive nature of the job and lower education level requirements for technicians have been reported as risk factors, little is known about the influence of burden of responsibility, degree of supervisor support, and home environment on burnout among emergency medical technicians. This study aimed to test the hypothesis that burden of responsibility, degree of supervisor support, and home environment increase burnout probability. METHODS A web-based survey was conducted among emergency medical technicians in Hokkaido, Japan from July 26, 2021 to September 13, 2021. A total of 21 facilities were randomly selected from 42 fire stations. Prevalence of burnout was measured using the Maslach Burnout-Human Services Survey Inventory (MBI-HSS). Burden of responsibility was measured using a visual analog scale. Occupational background was also measured. Supervisor support was measured using the Brief Job Stress Questionnaire (BJSQ). Family-work negative spillover was measured using the Japanese version of Survey Work-Home Interaction-NijmeGen (SWING). The cutoff value for burnout syndrome was defined as emotional exhaustion≥27 and/or depersonalization≥10. RESULTS A total of 700 survey respondents were included, and 27 surveys with missing data were excluded. The suspected burnout frequency was 25.6%. Covariates were adjusted using multilevel logistic regression model analysis. Low supervisor support (odds ratio, 1.421; 95% confidence interval, 1.136-1.406; P<0.001) and high family-work negative spillover (odds ratio, 1.264; 95% confidence interval, 1.285-1.571; P<0.001) were independent factors associated with higher probability of burnout. CONCLUSION This study indicated that focusing on improvement of supervisor support for emergency medical technicians and creating supportive home environments may assist in reducing burnout frequency.

Abstract
Background There has been an increase in emergency medical service (EMS) use for behavioral health reasons. Detroit Wayne Integrated Health Network (DWIHN) and Detroit East Medical Control Authority (DEMCA) collaborated to study the rising number of behavioral health (mental disorders and substance use disorders) calls to EMS. Methodology To examine the trend, DWIHN and DEMCA partnered on a data-sharing project and identified that a high volume of EMS runs (responses by EMS as a result of an emergency call) involved individuals served by DWIHN. Results Over a period of 2.5 years, an average of one-third (33.73%) of EMS runs involved individuals who receive behavioral health services through DWIHN. Conclusions DWIHN used the data to create interventions and internal process improvements that can help coordinate medical and behavioral healthcare for individuals who have been using EMS increasingly. The findings were also used to develop prevention efforts to decrease the occurrence of such crises and to avoid unwarranted member involvement with the justice system. We suggest that other comparable organizations consider similar partnerships, especially given the increasingly high EMS and Emergency Department use for behavioral health reasons.

Abstract
Introduction: Since December 2019, emergency services and Emergency Medical Service (EMS) systems have been at the forefront of the fight against the coronavirus disease 2019 (COVID-19) pandemic world-wide. Objective: The objective of this study was to examine the reasons and the necessity of transportation to the emergency department (ED) by ambulance and the outcomes of these cases with the admissions during the COVID-19 pandemic period and during the same period in 2019. Methods: A retrospective descriptive study was conducted in which patients transported to the ED by ambulance in April 2019 and April 2020 were compared. The primary outcomes were the changes in the number and diagnoses of patients who were transferred to the ED by ambulance during the COVID-19 period. The secondary outcome was the need for patients to be transferred to the hospital by ambulance. Results: A total of 4,466 patients were included in the study. During the COVID-19 period, there was a 41.6% decrease in ED visits and a 31.5% decrease in ambulance calls. The number of critically ill patients transported by ambulance (with diagnoses such as decompensated heart failure [P <.001], chronic obstructive pulmonary disease [COPD] attack (P = .001), renal failure [acute-chronic; P = .008], angina pectoris [P <.001], and syncope [P <.001]) decreased statistically significantly in 2020. Despite this decrease in critical patient calls, non-emergency patient calls continued and 52.2% of the patients transported by ambulance in 2020 were discharged from the ED. Conclusions: Understanding how the COVID-19 pandemic is affecting EMS use is important for evaluating the current state of emergency health care and planning to manage possible future outbreaks.

Analysis of the Adequacy of Prehospital Emergency Medical Services Use of Patients Who Visited Emergency Departments in Korea from 2016 to 2018: Data from the National Emergency Department Information System. Emerg Med Int 2021; 2021:6647149. [PMID: 33953985 PMCID: PMC8068549 DOI: 10.1155/2021/6647149] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2020] [Revised: 04/02/2021] [Accepted: 04/08/2021] [Indexed: 12/03/2022] Open
Abstract
Introduction Proper ambulance use is important not only due to the patient's transport quality but also because of the need for efficient use of limited resources allotted by the system. Therefore, this study was conducted to check for overuse or underuse of the ambulance system by patients who visited the emergency department (ED). Methods In this study, a secondary data analysis was conducted using the existing database of the National Emergency Department Information System with all patients who visited EDs over the three-year study period from 2016 to 2018. The study subjects were classified into the following groups: (1) appropriate Emergency Medical Services (EMS) usage; (2) appropriate no EMS usage; (3) underuse; and (4) overuse groups. Results Of 18,298,535 patients, 11,668,581 (63.77%) were classified under the appropriate usage group, while 6,629,954 (36.23%) were classified under the inappropriate usage group. In the appropriate EMS usage group, there were 2,408,845 (13.16%) patients. In the appropriate no EMS usage group, there were 9,259,706 (50.60%) patients. As for the inappropriate usage group, there were 5,147,352 (28.13%) patients categorized under the underuse group. On the other hand, there were 1,482,602 (8.10%) patients under the overuse group. Conclusion There are many patients who use ambulances appropriately, but there are still many overuse and underuse. Guidelines on ambulance use are necessary for the efficient use of emergency medical resources and for the safety of patients.

Outpatient care in acute and prehospital emergency medicine by emergency medical and patient transport service over a 10-year period: a retrospective study based on dispatch data from a German emergency medical dispatch centre (OFF-RESCUE). BMC Emerg Med 2021; 21:29. [PMID: 33750317 PMCID: PMC7941891 DOI: 10.1186/s12873-021-00424-4] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2020] [Accepted: 02/24/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The number of operations by the German emergency medical service almost doubled between 1994 and 2016. The associated expenses increased by 380% in a similar period. Operations with treatment on-site, which retrospectively proved to be misallocated (OFF-Missions), have a substantial proportion of the assignment of the emergency medical service (EMS). Besides OFF-Missions, operations with patient transport play a dominant role (named as ON-Missions). The aim of this study is to work out the medical and economic relevance of both operation types. METHODS This analysis examined N = 819,780 missions of the EMS and patient transport service (PTS) in the catchment area of the emergency medical dispatch centre (EMDC) Bad Kreuznach over the period from 01/01/2007 to 12/31/2016 in terms of triage and disposition, urban-rural distribution, duration of operations and economic relevance (p < .01). RESULTS 53.4% of ON-Missions are triaged with the indication non-life-threatening patient transport; however, 63.7% are processed by the devices of the EMS. Within the OFF-Mission cohort, 78.2 and 85.8% are triaged or dispatched for the EMS. 74% of all ON-Missions are located in urban areas, 26% in rural areas; 81.3% of rural operations are performed by the EMS. 66% of OFF-Missions are in cities. 93.2% of the remaining 34% of operations in rural locations are also performed by the EMS. The odds for both ON- and OFF-Missions in rural areas are significantly higher than for PTS (ORON 3.6, 95% CI 3.21-3.30; OROFF 3.18, 95% CI 3.04-3.32). OFF-Missions last 47.2 min (SD 42.3; CI 46.9-47.4), while ON-Missions are processed after 79.7 min on average (SD 47.6; CI 79.6-79.9). ON-Missions generated a turnover of more than € 114 million, while OFF-Missions made a loss of almost € 13 million. CONCLUSIONS This study particularly highlights the increasing utilization of emergency devices; especially in OFF-Missions, the resources of the EMS have a higher number of operations than PTS. OFF-Missions cause immensely high costs due to misallocations from an economic point of view. Appropriate patient management appears necessary from both medical and economic perspective, which requires multiple solution approaches.

Abstract
BackgroundThe increasing usage of emergency medical services (EMS) missions is a challenge in modern practice. This study was designed to examine the association of the income level of residential areas on the rate of EMS missions and the frequency of EMS use in these areas.MethodsAll EMS missions for adult patients (>18 years) encountered by one rescue department in Northern Finland between June 2015 and May 2017 were analysed. The area served was categorised into four categories, according to the median annual income of the postal code areas. EMS missions per 1000 person-years, rate of non-transport missions and the number of dispatches to frequent (>4 EMS calls/year and highly frequent (>10 calls/year)EMS users per area were investigated.ResultsThere were 62 759 EMS missions, 34.8% of which resulted in non-transport. The crude rate of EMS dispatches was higher in the low-income area compared with other income areas (133.3 vs 108.9 vs 111.3 vs 73.6/1000 person-years) as well as the rate of high-frequency user dispatches (21.5 vs 11.5 vs 7.2 vs 4.3/1000-person years). The rate of non-transports missions was higher also (69.4 vs 43.4 vs 42.5. vs 30.6/1000 person-years). The highest crude rate of EMS use was found in people older than 65 years living in the lowest income areas (294.8/1000 person-years). After age adjustment, the highest rate of EMS use was found in rural areas with the lowest income (146.3/1000 person-years).ConclusionsThe rate of the EMS missions and non-transport missions differs significantly among different income areas. Resource usage was significantly higher in the low income areas. This information can be used in planning allocation of EMS and preventive healthcare resources.

Abstract
Emergency telephone calls for an ambulance (999 calls) are usually dealt with first-come first-served. We have devised and assessed criteria that ambulance dispatch might use to prioritize responses. Data were collected retrospectively on consecutive patients presenting to an accident and emergency (A&E) department after a 999 call. An unblinded researcher abstracted data including age, date, time, caller, location, reason for call and A&E diagnosis and each case was examined for ten predetermined criteria necessitating an immediate ambulance response--namely, cardiac arrest; chest pain; shortness of breath; altered mental status/seizure; abdominal/loin pain >65 years old; fresh haematemesis; fall >2m; stabbing; major burns. 471 patients were recruited, 55% male, median age 50 years. 406 calls came from bystanders or the patients themselves, 36 from general practitioners, 8 from other hospitals and 21 from the police. 52% of patients were admitted. 44% met at least one of the above criteria. Most patients did not meet the criteria for an immediate ambulance response but might nonetheless be suitable for an urgent response. The criteria used in this study have the advantage of being based on the history provided by the caller. The introduction of a priority-based dispatch system could reduce response times to those who are seriously ill, and also improve road safety.

Abstract
OBJECTIVE To investigate the appropriateness of cases presenting to the emergency department (ED) following ambulance-based secondary telephone triage. DESIGN A pragmatic retrospective cohort analysis of all the planned and unplanned ED presentations within 48 hours of a secondary telephone triage. SETTING The secondary telephone triage service, called the Referral Service, and the hospitals were located in metropolitan Melbourne, Australia and operated 24 hours a day, servicing 4.25 million people. The Referral Service provides an in-depth secondary triage of cases classified as low acuity when calling the Australian emergency telephone number. POPULATION Cases triaged by the Referral Service between September 2009 and June 2012 were linked to ED and hospital admission records (N=44,523). Planned ED presentations were cases referred to the ED following the secondary triage, unplanned ED presentations were cases that presented despite being referred to alternative care pathways. MAIN OUTCOME MEASURES Appropriateness was measured using an ED suitability definition and hospital admission rates. These were compared with mean population data which consisted of all of the ED presentations for the state (termed the 'average Victorian ED presentation'). RESULTS Planned ED presentations were more likely to be ED suitable than unplanned ED presentations (OR 1.62; 95% CI 1.5 to 1.7; p<0.001) and the average Victorian ED presentation (OR 1.85; 95% CI 1.01 to 3.4; p=0.046). They were also more likely to be admitted to the hospital than the unplanned ED presentation (OR 1.5; 95% CI 1.4 to 1.6; p<0.001) and the average Victorian ED presentation (OR 2.3, 95% CI 2.24 to 2.33; p<0.001). Just under 15% of cases diverted away from the emergency care pathways presented in the ED (unplanned ED attendances), and 9.5% of all the alternative care pathway cases were classified as ED suitable and 6.5% were admitted to hospital. CONCLUSIONS Secondary telephone triage was able to appropriately identify many ED suitable cases, and while most cases referred to alternative care pathways did not present in the ED. Further research is required to establish that these were not inappropriately triaged away from the emergency care pathways.

Abstract
Objective This study investigated medically unnecessary emergency medical services (EMS) transportation by comparing non-intoxicated versus intoxicated patients who did not receive emergency department (ED) treatment but utilized EMS transport. Methods Patients who used EMS but did not receive ED treatment were classified into non-intoxicated and intoxicated groups. Reasons for not receiving ED treatment were categorized according to whether the decision was made by the patient against medical advice or if the decision was based on a physician’s evaluation and their recommendations. Results There were 212 patients reviewed; 120 in the non-intoxicated group and 92 in the intoxicated group. The intoxicated group had a higher proportion of males than the non-intoxicated group. The most common cause of non-disease symptoms in the intoxicated group was assault. In the non-intoxicated group, the most common reason for the lack of ED treatment was that treatment could take place on an outpatient basis, while in the intoxicated group, the reason was lack of patient cooperation. Conclusions The intoxicated group was older, male and more likely to present with symptoms not related to a disease process than those in the non-intoxicated group when using unnecessary EMS transport.

Abstract
The goal of this study was to understand safety climate in the United States (U.S.) fire service, which responded to more than 31 million calls to the 9-1-1 emergency response system in 2013. The majority of those calls (68 %) were for medical assistance, while only 4 % of calls were fire-related, highlighting that the 9-1-1 system serves as a critical public health safety net. We conducted focus groups and interviews with 123 firefighters from 12 fire departments across the United States. Using an iterative analytic approach supported by NVivo 10 software, we developed consensus regarding key themes. Firefighters concurred that the 9-1-1 system is strained and increasingly called upon to deliver Emergency Medical Services (EMS) in the community. Much like the hospital emergency department, EMS frequently assists low-income and elderly populations who have few alternative sources of support. Firefighters highlighted the high volume of low-acuity calls that occupy much of their workload, divert resources from true emergencies, and lead to unwarranted occupational hazards like speeding to respond to non-serious calls. As a result, firefighters reported high occupational stress, low morale, and desensitization to community needs. Firefighters' called for improvements to the 9-1-1 system-the backbone of emergency response in the U.S.-including better systems of triage, more targeted use of EMS resources, continuing education to align with job demands, and a strengthened social safety net to address the persistent needs of poor and elderly populations.

Abstract
Objective The aim of the present study was to describe the Ambulance Victoria (AV) secondary telephone triage service, called the Referral Service (RS), for low-priority patients calling triple zero. This service provides alternatives to ambulance dispatch, such as doctor or nurse home visits. Methods A descriptive epidemiological review of all the cases managed between 2009 and 2012 was conducted, using data from AV case records, the Victorian Admitted Episodes Dataset and the Australian Bureau of Statistics. Cases were reviewed for patient demographics, condition, final disposition and RS outcome. Results In all, 107148 cases were included in the study, accounting for 10.3% of the total calls for ambulance attendance. Median patient age was 54 years and 55% were female. Geographically based socioeconomic status was associated with the rate of calls to the RS (r = –0.72; 95% confidence interval CI –0.104, –0.049; P < 0.001). Abdominal pain and back symptoms were the most common patient problems. Although 68% of patients were referred to the emergency department, only 27.6% of the total cases were by emergency ambulance; the remainder were diverted to non-emergency ambulance or the patient’s own private transport. The remaining 32% of cases were referred to alternative service providers or given home care advice. Conclusions This paper describes the use of an ongoing secondary triage service, providing an effective strategy for managing emergency ambulance demand. What is known about the topic? Some calls to emergency services telephone numbers for ambulance assistance consist of cases deemed to be low-acuity that could potentially be better managed in the primary care setting. The demand on ambulance resources is increasing each year. Secondary telephone triage systems have been trialled in ambulance services in the US and UK with minimal success in terms of overall impact on ambulance resourcing. What does this paper add? This study describes a model of secondary telephone triage in the ambulance setting that has provided an effective way to divert patients to more suitable forms of health care to meet their needs. What are the implications for practitioners? The implications for practitioners are vast. Some of the issues that currently face paramedics include: fatigue because of high workloads; skills decay because of a lack of exposure to patients requiring intervention with skills the paramedics have, as well as a lack of time for paramedics to practice these skills during their downtime; and decreasing job satisfaction linked to both these factors. Implications for patients include quicker response times because more ambulances will be available to respond and increased patient safety because of decreased fatigue and higher skill levels in paramedics.

Norman C, Mello M, Choi B. Identifying Frequent Users of an Urban Emergency Medical Service Using Descriptive Statistics and Regression Analyses. West J Emerg Med 2016; 17:39-45. [PMID: 26823929 PMCID: PMC4729417 DOI: 10.5811/westjem.2015.10.28508] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2015] [Revised: 10/13/2015] [Accepted: 11/01/2015] [Indexed: 11/16/2022] Open
Abstract
This retrospective cohort study provides a descriptive analysis of a population that frequently uses an urban emergency medical service (EMS) and identifies factors that contribute to use among all frequent users. For purposes of this study we divided frequent users into the following groups: low- frequent users (4 EMS transports in 2012), medium-frequent users (5 to 6 EMS transports in 2012), high-frequent users (7 to 10 EMS transports in 2012) and super-frequent users (11 or more EMS transports in 2012). Overall, we identified 539 individuals as frequent users. For all groups of EMS frequent users (i.e. low, medium, high and super) one or more hospital admissions, receiving a referral for follow-up care upon discharge, and having no insurance were found to be statistically significant with frequent EMS use (P<0.05). Within the diagnostic categories, 41.61% of super-frequent users had a diagnosis of "primarily substance abuse/misuse" and among low-frequent users a majority, 53.33%, were identified as having a "reoccurring (medical) diagnosis." Lastly, relative risk ratios for the highest group of users, super-frequent users, were 3.34 (95% CI [1.90-5.87]) for obtaining at least one referral for follow-up care, 13.67 (95% CI [5.60-33.34]) for having four or more hospital admissions and 5.95 (95% CI [1.80-19.63]) for having a diagnoses of primarily substance abuse/misuse. Findings from this study demonstrate that among low- and medium-frequent users a majority of patients are using EMS for reoccurring medical conditions. This could potentially be avoided with better care management. In addition, this study adds to the current literature that illustrates a strong correlation between substance abuse/misuse and high/super-frequent EMS use. For the subgroup analysis among individuals 65 years of age and older, we did not find any of the independent variables included in our model to be statistically significant with frequent EMS use.

Abstract
ABSTRACTBackground:Within the emergency department (ED) patient population there is a subset of patients who make frequent visits. This chart review sought to characterize this population and identify strategies to reduce frequent ED visits.Methods:Frequent use at an urban tertiary care centre was defined as 15 or more visits over 1 year. The details of each visit—demographics, entrance complaint, discharge diagnosis, arrival method, Canadian Triage and Acuity Scale (CTAS) score, and length of stay—were analyzed and compared to data from the entire ED population for the same period.Results:Ninety-two patients generated 2,390 ED visits (of 25,523 patients and 44,204 visits). This population was predominantly male (66%) and middle-aged (median 42 years), with no fixed address (27.2%). Patients arrived by ambulance in 59.3% of visits with less acute CTAS scores than the general population. Substance use accounted for 26.9% of entrance complaints. Increased lengths of stay were associated with female gender and abnormal vital signs, whereas shorter stays were associated with no fixed address and substance use (p< 0.05). Admissions were lower than the general population, and women were twice as likely as men to be admitted (p< 0.05). Patients left without being seen in 15.8% of visits.Conclusions:High-frequency ED users are more likely to be male, younger, and marginally housed and to present secondary to substance use. Although admissions among this population are low, the costs associated with these presentations are high. Interventions designed to decrease visits and improve the health of this population appear warranted.

Abstract
BACKGROUND Among surgical patients, follow-up visits are essential for monitoring post-operative recovery and determining ongoing treatment plans. Non-adherence to clinic follow-up appointments has been associated with poorer outcomes in many different patient populations. We sought to identify factors associated with non-attendance at follow-up appointments for orthopedic trauma patients. MATERIALS AND METHODS A retrospective chart review at a level I trauma center identified 2,165 patients who underwent orthopedic trauma surgery from 2008 to 2009. Demographic data including age, sex, race, tobacco use, American Society of Anesthesiologist (ASA) score, insurance status, distance from the hospital, and follow-up time were collected. Injury characteristics including fracture type, anatomic location of the operation, length of hospital stay, living situation and employment status were recorded. Attendance at the first scheduled follow-up visit was recorded. Multivariable log-binomial regression analyses were used with statistical significance maintained at p < 0.05. RESULTS Of the 2,165 patients included in the analysis, 1,449 (66.9 %) attended their first scheduled post-operative clinic visit. 33.1 % (717) were not compliant with keeping their first clinic appointment after surgery. Patients who used tobacco, lived more than 100 miles from the clinic site, did not have private insurance, had an ASA score >2, or had a fracture of the hip or pelvis were significantly less likely to follow-up. Age, sex, and race were not significantly associated with failure to follow-up. DISCUSSION Follow-up appointments are essential for preventing complications among orthopedic trauma patients. By identifying patients at risk of failure to follow-up, orthopedic surgeons can appropriately design and implement long-term treatment plans specifically targeted for high-risk patients.

Patient and trauma center characteristics associated with helicopter emergency medical services transport for patients with minor injuries in the United States. Acad Emerg Med 2014; 21:1232-9. [PMID: 25377400 DOI: 10.1111/acem.12512] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2014] [Revised: 07/06/2014] [Accepted: 07/16/2014] [Indexed: 11/27/2022]
Abstract
BACKGROUND Helicopter emergency medical services (EMS) transport is expensive, and previous work has shown that cost-effective use of this resource is dependent on the proportion of minor injuries flown. To understand how overtriage to helicopter EMS versus ground EMS can be reduced, it is important to understand factors associated with helicopter transport of patients with minor injuries. OBJECTIVES The aim was to characterize patient and hospital characteristics associated with helicopter transport of patients with minor injuries. METHODS This was a retrospective analysis of adults ≥18 years who were transported by helicopter to Level I/II trauma centers from 2009 through 2010 as identified in the National Trauma Data Bank. Minor injuries were defined as all injuries scored at an Abbreviated Injury Scale (AIS) score of <3. Patient and hospital characteristics associated of being flown with only minor injuries were compared in an unadjusted and adjusted fashion. Hierarchical, multivariate logistic regression was used to adjust for patient demographics, mechanism of injury, presenting physiology, injury severity, urban-rural location of injury, total EMS time, hospital characteristics, and region. RESULTS A total of 24,812 records were identified, corresponding to 76,090 helicopter transports. The proportion of helicopter transports with only minor injuries was 36% (95% confidence interval [CI] = 34% to 39%). Patient characteristics associated with being flown with minor injuries included being uninsured (odds ratio [OR] = 1.36, 95% CI = 1.26 to 1.47), injury by a fall (OR = 1.32, 95% CI = 1.20 to 1.45), or other penetrating trauma (OR = 2.52, 95% CI = 2.12 to 3.00). Being flown with minor injuries was more likely if the patient was transported to a trauma center that also received a high proportion of patients with minor injuries by ground EMS (OR = 1.89, 95% CI = 1.58 to 2.26) or a high proportion of EMS traffic by helicopter (OR = 1.35, 95% CI = 1.02 to 1.78). No significant association with urban-rural scene location or EMS transport time was found. CONCLUSIONS Better recognizing which patients with falls and penetrating trauma have serious injuries that could benefit from being flown may lead to the more cost-effective use of helicopter EMS. More research is needed to determine why patients without insurance, who are most at risk for high out-of-pocket expenses from helicopter EMS, are at higher risk for being flown when only having minor injuries. This suggests that interventions to optimize cost-effectiveness of helicopter transport will likely require an evaluation of helicopter triage guidelines in the context of regional and patient needs.

Abstract
OBJECTIVE Secondary telephone triage to divert low-acuity patients to alternative non-ambulance services before ambulance arrival has been trialled in the UK and USA as a management strategy to cope with the increase in ambulance demand. The objective of this systematic review was to examine the literature on the structure, safety and success of secondary triage systems. METHODS For inclusion in the study, the telephone triage system had to be a secondary process, receiving referred patients who had already been categorised as low priority by a primary triage process. Two independent reviewers conducted the search to identify relevant studies. Six articles and one report were identified. RESULTS The major theme of the papers was the safety and accuracy of secondary telephone triage in identifying low-acuity patients. Two studies also discussed patient satisfaction. There was a low incidence of adverse events, as expected as these patients had already been subjected to primary telephone triage. In the studies identifying ambulance dispatch as a potential final disposition, at least half of the patients were diverted away from ambulance dispatch. In the studies that identified self/home care as a final disposition, a maximum of 31% of patients were categorised to this outcome. Otherwise all patients were recommended for assessment by a healthcare professional other than ambulance clinicians. Patients appeared to be satisfied with secondary telephone triage on follow-up. CONCLUSIONS These results suggest that, while secondary triage of these patients is safe, further research is required to determine its most appropriate structure and its effect on ambulance demand.

Abstract
OBJECTIVES The objective was to study the role and effect of patients' perceptions on reasons for using ambulance services in Queensland, Australia. METHODS A cross-sectional survey was conducted of patients (n = 911) presenting via ambulance or self-transport at eight public hospital emergency departments (EDs). The survey included perceived illness severity, attitudes toward ambulance, and reasons for using ambulance. A theoretical framework was developed to inform this study. RESULTS Ambulance users had significantly higher self-rated perceived seriousness, urgency, and pain than self-transports. They were also more likely to agree that ambulance services are for everyone to use, regardless of the severity of their conditions. In compared to self-transports, likelihood of using an ambulance increased by 26% for every unit increase in perceived seriousness; and patients who had not used an ambulance in the 6 months prior to the survey were 66% less likely to arrive by ambulance. Patients who had presented via ambulance stated they considered the urgency (87%) or severity (84%) of their conditions as reasons for calling the ambulance. Other reasons included requiring special care (76%), getting higher priority at the ED (34%), not having a car (34%), and financial concerns (17%). CONCLUSIONS Understanding patients' perceptions is essential in explaining their actions and developing safe and effective health promotion programs. Individuals use ambulances for various reasons and justifications according to their beliefs, attitudes, and sociodemographic conditions. Policies to reduce and manage demand for such services need to address both general opinions and specific attitudes toward emergency health services to be effective.

Abstract
AbstractStudy objective:To determine the ability of emergency medical services (EMS) providers to subjectively triage patients with respect to hospital admission and to determine patient characteristics associated with increased likelihood of admission.Methods:A prospective, cross-sectional study of a consecutive sample of patients arriving by ambulance during the month of February 1997 at an urban, university hospital, Emergency Department. Emergency medical services providers completed a questionnaire asking them to predict admission to the hospital and requested patient demographic information. Predictions were compared to actual patient disposition.Results:A total of 887 patients were included in the study, and 315 were admitted to the hospital (36%). With respect to admission, emergency medical services providers had an accuracy rate of 79%, with a sensitivity of 72% and specificity of 83% (kappa = 0.56). Blunt traumatic injury and altered mental status were the most common medical reasons for admission. Variables significantly associated with high admission rates were patients with age > 50 years, chest pain or cardiac complaints, shortness of breath or respiratory complaints, Medicare insurance, and Hispanic ethnicity. The emergency medical services providers most accurately predicted admission for patients presenting with labor (kappa = 1.0), shortness of breath / respiratory complaints (kappa = 0.84), and chest pain (kappa = 0.77).Conclusion:Emergency medical services providers can predict final patient disposition with reasonable accuracy, especially for patients presenting with labor, shortness of breath, or chest pain. Certain patient characteristics are associated with a higher rate of actual admission.

Abstract
The purpose of this study was to generate national estimates of the prevalence of medically unnecessary emergency medical services (EMS) transports to emergency departments (EDs) over time and to identify characteristics that may be associated with medically unnecessary transports. A previously published algorithm was applied to operationalize medical necessity based on ED diagnosis to 10 years of data from the National Hospital Ambulatory Medical Care Survey. The trend over time was reported using descriptive statistics weighted to produce national estimates. Nationally, the proportion of EMS transports that were medically unnecessary increased from 13% to 17% over the 10-year study period. Individual demographic characteristics, including insurance status, were not predictive of inappropriate utilization. EMS transports for medically unnecessary complaints increased from 1997 to 2007. Our findings from a nationally representative sample highlight the opportunity for alternative patient delivery strategies for select patients seeking EMS services.

Abstract
OBJECTIVES The purpose of this study was to describe the associations between individual health insurance and ambulance utilization using a national sample of patients who receive emergency department (ED) care. METHODS The data source was the National Hospital Ambulatory Medical Care Survey, years 2004 through 2006. Noninstitutionalized patients between ages 18 and 65 years were included. The primary dependent variable was ambulance use. Multivariable logistic regression methods were used to assess the associations between health insurance status and ambulance use and to adjust for confounders. RESULTS A total of 61,013 ED visits were included, representing a national sample of approximately 70 million annual ED visits over 3 years. Ambulance transport was used in 11% of private insurance visits, 16% of Medicaid visits, and 13% of uninsured visits. In the adjusted model, visits by patients with Medicaid (adjusted odds ratio [aOR] = 1.60, 99% confidence interval (CI) = 1.37 to 1.86) and the uninsured (aOR = 1.43, 99% CI = 1.23 to 1.66) were more likely to arrive by ambulance than visits by patients with private insurance. Ambulance use among the uninsured was most pronounced in metropolitan areas. CONCLUSIONS Ambulance use varies by health insurance status. Medicaid coverage and lack of insurance are each independently associated with increased odds of ambulance use, suggesting a disproportionate role for emergency medical services (EMS) in the care of patients with limited financial resources.

Abstract
The aim of this study is to determine the use of pre-hospital emergency medical services (EMS) in elderly people aged 65 years and over in Izmir, Turkey. In this descriptive study, older patients admitted to pre-hospital EMS of Izmir Province Health Directorate between 2004 and 2005 years was evaluated through the review of Emergency Call Registry Forms. The study data included socioeconomic characteristics, reasons of calling, distribution of calling times in the day, distribution of ambulance callers and preclinical diagnosis. A total of 34% of the subjects admitted to pre-hospital EMS were 65 years old and over. The rate of the use of ambulance services was 68.9/1000 population/year. The rate of pre-hospital EMS use for older persons living in urban areas was significantly higher than that of those living in rural areas. The most frequent pre-hospital EMS caller were persons in family (70.7%), and utilization of ambulance services was the highest in winter. Medically related incidents accounted for 89.1% of all emergency ambulance calls and cardiovascular diseases accounted for most common cause (32.6%) of calls. The utilization rate of pre-hospital EMS among older persons was approximately four times higher than that of the younger age groups.

Abstract
Background Unnecessary ambulance use has become a socioeconomic problem in Japan. We investigated the possible relations between socioeconomic factors and medically unnecessary ambulance calls, and we estimated the incremental demand for unnecessary ambulance use produced by socioeconomic factors. Methods We conducted a self-administered questionnaire-based survey targeting residents of Yokohama, Japan. The questionnaire included questions pertaining to socioeconomic characteristics, dichotomous choice method questions pertaining to ambulance calls in hypothetical nonemergency situations, and questions on the city's emergency medical system. The probit model was used to analyze the data. Results A total of 2,029 out of 3,363 targeted recipients completed the questionnaire (response rate, 60.3%). Probit regression analyses showed that several demographic and socioeconomic factors influence the decision to call an ambulance. Male respondents were more apt than female respondents to state that they would call an ambulance in nonemergency situations (p < 0.05). Age was an important factor influencing the hypothetical decision to call an ambulance (p < 0.05); elderly persons were more apt than younger persons to state that they would call an ambulance. Possession of a car and hesitation to use an ambulance negatively influenced the hypothetical decision to call an ambulance (p < 0.05). Persons who do not have a car were more likely than those with a car to state that they would call an ambulance in unnecessary situations. Conclusion Results of the study suggest that several socioeconomic factors, i.e., age, gender, household income, and possession of a car, influence a person's decision to call an ambulance in nonemergency situations. Hesitation to use an ambulance and knowledge of the city's primary emergency medical center are likely to be important factors limiting ambulance overuse. It was estimated that unnecessary ambulance use is increased approximately 10% to 20% by socioeconomic factors.

Resuscitation 2006; 71:171-9. [PMID: 16987580 DOI: 10.1016/j.resuscitation.2006.03.016] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2005] [Revised: 03/20/2006] [Accepted: 03/29/2006] [Indexed: 10/24/2022]
Abstract
INTRODUCTION Implementing prehospital advanced life support (ALS) services requires more medical and societal resources in training and equipment. The actual demand for ALS services in our communities was not clear. To ensure good use of expensive resources, it is important to evaluate the demand and appropriateness of ALS services before full-scale implementation takes place. OBJECTIVE To evaluate the rate and characteristics of demand for ALS, and the appropriateness of ALS dispatch of the emergency medical service (EMS) system in metropolitan Taipei City. METHODS A retrospective, cross-sectional analysis of the EMS records of Taipei City Fire Department from April 1999 to December 2000 was conducted. Stratified random sampling of all EMS records in the second week of January, April, July and October of 2000 were obtained, along with the corresponding ALS dispatch records. Retrospective ALS demand criteria, including the chief complaints, mechanisms of injury/illness, initial vital signs and types of care rendered, were developed to estimate the rate of ALS demand. ALS demand is expressed as the percentage of cases fulfilling ALS criteria over the total number of EMS cases. Appropriate ALS dispatches were those ALS dispatches determined as fulfilling the ALS demand criteria. RESULTS Among the sampled 5433 EMS cases, 490 (9.02%) were determined as a demand for ALS care. ALS demands varied from region to region, and were higher during winter months and afternoon rush hours. There were 175 actual ALS dispatches, accounting for 3.22% of the sampled EMS services. The triage performance was suboptimal: the appropriateness of ALS dispatch was 37.14%; the overtriage rate was 72.86%. CONCLUSION Around nine percent of EMS calls demand ALS services. The current triage performance for proper ALS dispatch was suboptimal. A correct ALS dispatch protocol and more dispatcher training programmes should be established in the communities to ensure best use of valuable ALS resources.

Abstract
BACKGROUND Concern about ambulance diversion and emergency department (ED) overcrowding has increased scrutiny of ambulance use. Knowledge is limited, however, about clinical and economic factors associated with ambulance use compared to other arrival methods. OBJECTIVES To compare clinical and economic factors associated with different arrival methods at a large, urban, academic hospital ED. METHODS This was a retrospective, cross-sectional study of all patients seen during 2001 (N = 80,209) at an urban academic hospital ED. Data were obtained from hospital clinical and financial records. Outcomes included acuity and severity level, primary complaint, medical diagnosis, disposition, payment, length of stay, costs, and mode of arrival (bus, car, air-medical transport, walk-in, or ambulance). Multivariate logistic regression identified independent factors associated with ambulance use. RESULTS In multivariate analysis, factors associated with ambulance use included: triage acuity A (resuscitation) (adjusted odds ratio [OR], 51.3; 95% confidence interval [CI] = 33.1 to 79.6) or B (emergent) (OR, 9.2; 95% CI = 6.1 to 13.7), Diagnosis Related Group severity level 4 (most severe) (OR, 1.4; 95% CI = 1.2 to 1.8), died (OR, 3.8; 95% CI = 1.5 to 9.0), hospital intensive care unit/operating room admission (OR, 1.9; 95% CI = 1.6 to 2.1), motor vehicle crash (OR, 7.1; 95% CI = 6.4 to 7.9), gunshot/stab wound (OR, 2.1; 95% CI = 1.5 to 2.8), fell 0-10 ft (OR, 2.0; 95% CI = 1.8 to 2.3). Medicaid Traditional (OR, 2.0; 95% CI = 1.4 to 2.4), Medicare Traditional (OR, 1.8; 95% CI = 1.7 to 2.1), arrived weekday midnight-8 am (OR, 2.0; 95% CI = 1.8 to 2.1), and age > or =65 years (OR, 1.3; 95% CI = 1.2 to 1.5). CONCLUSIONS Ambulance use was related to severity of injury or illness, age, arrival time, and payer status. Patients arriving by ambulance were more likely to be acutely sick and severely injured and had longer ED length of stay and higher average costs, but they were less likely to have private managed care or to leave the ED against medical advice, compared to patients arriving by independent means.

Abstract
STUDY OBJECTIVE We determine the impact of a treatment strategy called the San Diego Serial Inebriate Program on the use of emergency medical services (EMS) and emergency department (ED) and inpatient services by individuals repeatedly arrested for public intoxication. METHODS This was a retrospective review of health care utilization records (EMS, ED, and inpatient) of 529 individuals from 2000 to 2003. Judges offered individuals a 6-month outpatient treatment program in lieu of custody (Serial Inebriate Program). Demographics and health care utilization are reported overall and by treatment acceptance. RESULTS From 2000 to 2003, 308 of 529 (58%) individuals were transported by EMS 2,335 times; 409 of 529 (77%) individuals amassed 3,318 ED visits, and 217 of 529 (41%) individuals required 652 admissions, resulting in 3,361 inpatient days. Health care charges totaled $17.7 million (EMS, $1.3 million; ED, $2.5 million; and inpatient, $13.9 million). Treatment was offered to 268 individuals, and 156 (58%) accepted. Use of EMS, ED, and inpatient services declined by 50% for clients who chose treatment, resulting in an estimated decrease in total monthly average charges of $5,662 (EMS), $12,006 (ED), and $55,684 (inpatient). There was no change in use of services for individuals who refused treatment. There was a significant increasing trend in acceptance among individuals with longer jail sentences (<0.001). Treatment acceptance was 20% among those with sentences of 0 to 30 days and reached 63% for those with sentences longer than 150 days. Operational costs and alternate care at clinics and nonparticipating hospitals were not analyzed. CONCLUSION This community-supported treatment strategy reduced the use of EMS, ED, and inpatient resources by individuals repeatedly intoxicated in public.

Abstract
INTRODUCTION Understanding ambulance utilization patterns is essential to assessing prehospital system capacity and preparedness at the national level. OBJECTIVE To describe the characteristics of patients transported to U.S. emergency departments (EDs) by ambulance and to determine predictors of ambulance utilization. METHODS Data were obtained from the National Hospital Ambulatory Medical Care Survey using mode of arrival, demographic and visit information, ICD-9-CM E and V-codes, and classified reasons for the visit. RESULTS The rates for ED visits of persons conveyed by ambulence were stable between 1997 and 2003, consisting of approximately one in every seven ED visits (14%). In 2003, there were 16.2 million ED visits for which an ambulance was used in the U.S. However, for patients with mental health visits, nearly one in three ED presentations (31%) arrived by ambulance. Significantly higher rates of ambulance use were associated with: (1) mental health visits; (2) older age; (3) African-Americans; (4) Medicare or self-pay insurance status; (5) urban ED location; (6) U.S. regions outside of the South; (7) presentation between 12 midnight to 0800 hours; (8) injury-related visits; (9) urgent visit status; and/or (10) those resulting in hospital admission. Among mental health patients, older age, self-pay insurance status, urban ED location, regions outside the southern US, and urgent visit classification predicted ambulance use. Ambulance usage within the mental health group was highest for suicide and lowest for mood and anxiety disorder-related visits. CONCLUSION Reliance on ambulance services varies by age, insurance status, geographic factors, time of day, urgency of visit, subsequent admission status, and type of mental health disorder. Even after controlling for many confounding factors, mental health problems remain an important predictor of ambulance use.

Abstract
To compare the outcomes of patients who were denied transport by emergency medical services (EMS) with those who refused to be transported, all EMS non-transports were reviewed to determine who refused the transport and adherence to mandatory transport guidelines. Patients were contacted for telephone survey. Of 906 non-transported patients, 310 consented to the survey. Of these, 205 were patient refusals and 105 were EMS refusals. There was no significant difference between the patient and EMS refusal groups in reported change in medical care, hospitalization, or death. One hundred ten non-transported patients met mandatory transport criteria (85 patient refusals vs. 25 EMS refusals, p = 0.002). In conclusion, patient non-transport may result in adverse outcomes that are as likely to occur in patients who are denied transport by EMS as those who refuse to be transported. Patients who refuse transport are more likely to meet mandatory transport guidelines.

Abstract
OBJECTIVE Emergency medical service providers frequently encounter patients with low acuity. Because of liability and safety concerns, emergency medical service systems often prohibit privately owned vehicle (POV) transport. Thus, prehospital resources are used with questionable benefit. In Sequoia and Kings Canyon National Parks, our primary objective was to determine the feasibility of POV. We assessed patient compliance, satisfaction, and safety. Our hypothesis was that POV is feasible with online physician medical control. METHODS This study was a prospective observational analysis of outcomes from POV during a 1-year period. All POV patients were advised to seek medical attention at a hospital. POV patients were asked questions about their medical complaint and the events during transport and at the hospital. RESULTS No documented admissions or patient deterioration was noted. During the survey, all patients were either "all better" (86%) or "somewhat better" (14%). CONCLUSION We conclude that POV with carefully selected patients and online physician medical control is feasible and deserves further study in other systems.

Abstract
OBJECTIVE To assess the safety of nurses and paramedics offering telephone assessment, triage, and advice as an alternative to immediate ambulance dispatch for emergency ambulance service callers classified by lay call takers as presenting with "non-serious" problems (category C calls). DESIGN Data for this study were collected as part of a pragmatic randomised controlled trial reported elsewhere. The intervention arm of the trial comprised nurse or paramedic telephone consultation using a computerised decision support system to assess, triage, and advise patients whose calls to the emergency ambulance service had been classified as "non-serious" by call takers applying standard priority dispatch criteria. A multidisciplinary expert clinical panel reviewed data from ambulance service, accident and emergency department, hospital inpatient and general practice records, and call transcripts for patients triaged by nurses and paramedics into categories that indicated that dispatch of an emergency ambulance was unnecessary. All cases for which one or more members of the panel rated that an emergency ambulance should have been dispatched were re-reviewed by the entire panel for an assessment of the "life risk" that might have resulted. SETTING Ambulance services in London and the West Midlands, UK. STUDY POPULATION Of 635 category C patients assessed by nurses and paramedics, 330 (52%) cases that had been triaged as not requiring an emergency ambulance were identified. MAIN OUTCOME MEASURES Assessment of safety of triage decisions. RESULTS Sufficient data were available from the routine clinical records of 239 (72%) subjects to allow review by the specialist panel. For 231 (96.7%) sets of case notes reviewed, the majority of the panel concurred with the nurses' or paramedics' triage decision. Following secondary review of the records of the remaining eight patients, only two were rated by the majority as having required an emergency ambulance within 14 minutes. For neither of these did a majority of the panel consider that the patient would have been at "life risk" without an emergency ambulance being immediately dispatched. However, the transcripts of these two calls indicated that the correct triage decision had been communicated to the patient, which suggests that the triage decision had been incorrectly entered into the decision support system. CONCLUSIONS Telephone advice may be a safe method of managing many category C callers to 999 ambulance services. A clinical trial of the full implementation of this intervention is needed, large enough to exclude the possibility of rare adverse events.

Abstract
OBJECTIVE It has been estimated that between 11% and 61% of ambulance transports to emergency departments are not medically necessary. This study's objective was to analyze paramedic ability to determine the medical necessity of ambulance transport to the emergency department. METHODS Paramedics prospectively assessed adult patients transported to an emergency department during a six-week period. The setting was an urban, all advanced life support, public utility model emergency medical services (EMS) system with 58,000 transports per year. Paramedics determined medical necessity of patient transport based on the following five criteria: 1) need for out-of-hospital intervention; 2) need for expedient transport; 3) potential for self-harm; 4) severe pain; or 5) other. On arrival in the emergency department, the emergency physician made a blinded determination based on the same criteria. Kappa statistics were used to assess agreement. RESULTS Data forms were completed on 825 of 1,420 (58%) patients transported. Emergency physicians determined 248 (30%) transports were not necessary, paramedics 236 (29%), with agreement in 76.2% (K=0.42) of cases. Paramedics undertriaged 92 patients (11%). Rates of agreement on the five criteria were: 1) 71.9% (K=0.43); 2) 77.7% (K=0.22); 3) 89.6% (K=0.40); 4) 89.6 (K=0.32); and 5) 82.2% (K=0.29). CONCLUSIONS Paramedics and emergency physicians agreed that a significant percentage of patients did not require ambulance transport to the emergency department. Despite only moderate agreement regarding which patients needed transport, the undertriage rate was low.

Abstract
OBJECTIVES To develop guidelines allowing emergency medical services (EMS) dispatchers to safely match callers to an EMS response or, alternatively, to a nontraditional resource. METHODS This was a prospective cohort study of callers to an urban EMS dispatch center and an associated review of EMS patient care forms and emergency department (ED) patient care records. The following five "nature codes" (patient chief complaints) were included: back pain, fall, bleeding or laceration, sick, and trauma. Callers included in the study had been assigned the lowest severity level (Alpha), according to existing dispatch criteria. An a priori list of EMS and ED "important findings," indicating need for an EMS response, was used as the outcome variable. Classification and regression tree (CART) analysis was used to develop a decision rule to further identify a low-risk subgroup of patients who could potentially be served by alternative resources. RESULTS From November 1, 1998, to May 31, 1999, 656 subjects were entered into the study, including 263 males (40%) and 389 females (59%). The mean age was 51 years (range, 0-101 years). One hundred twenty-five (19%) callers had an important EMS finding, including the administration of comfort medications, morphine, benzodiazepines, and droperidol. Forty-six subjects (7%) had an important ED finding. When EMS and ED findings were combined, 158 subjects (24%) had an "important finding." Using CART analysis, having an age <12 years predicted a subset of patients who did not have an important finding suggesting the need for an EMS response. Using cross-validation, this decision rule had a 99% sensitivity, 13% specificity, and 98% negative predictive value. CONCLUSION The authors were able to use a demographic variable (age) to predict a population of callers to a 911 dispatch center triaged to the lowest acuity category, who have a very low risk of having an EMS or ED important finding. The decision rule developed here is preliminary, requiring further validation.

Abstract
OBJECTIVE Recent American Heart Association (AHA) guidelines have suggested that advanced life support (ALS) providers should have "regular field experience," defined as six to 12 intubations/year, as a prerequisite to patient endotracheal intubation (EI). The authors sought to assess the impact of this guideline on rural emergency medical services (EMS) practice. METHODS Statewide EMS records were reviewed for the calendar years 1997-2001. Data reviewed included the number of providers eligible to perform ALS skills (including EI), number of procedures performed per year by EMS provider, patient age, gender, and prehospital diagnosis. The institutional review board approved the study. RESULTS During the study period, a total of 957,836 patient encounters occurred with an average of 1,352 ALS providers annually eligible to perform EI. In the five-year period, there were 5,615 total EI attempts with a range of 37%-42% of eligible providers annually performing EI. A mean of 18 providers per year with a range of 1.8%-0.8% of EI-eligible providers annually attempted EI in more than five patients. One hundred thirty-seven pediatric EI encounters occurred during the five-year period with an annual range of 1.4%-2.7% of eligible providers attempting pediatric EI. During the five-year investigation, EI success rate was reported as 84% by providers with fewer than five annual intubation encounters and 86% by providers with more than five encounters. CONCLUSION Rural EMS providers rarely use EI skills, particularly in pediatric patients. If recent AHA intubation guidelines are to be followed in rural EMS settings, a small number of EMS providers will meet minimum EI utilization requirements.

Abstract
OBJECTIVE The authors sought to determine if the availability of an after-hours on-call emergency physician by telephone for consultation to the staff at a county jail would safely reduce ambulance emergency department (ED) transport of inmates in the community. METHODS The authors conducted a prospective comparison study during the first ten months of an emergency physician on-call program for the county jail in which prospective data were collected on all consultations, including reason for call and disposition (ambulance, deputy, or no ED transport of inmate). They compared this time with a similar period a year before the program in terms of total ambulance transports from the jail. They also reviewed all hospital and jail medical records to assess for any adverse consequences within one month, or subsequent ambulance transport within 24 hours as a result of inmate care after the consultation call. RESULTS Total after-hours ambulance transports from the jail decreased significantly from 30.3 transports/month (95% confidence interval [CI], 21.0-39.6) to 9.1 transports/month (95% CI, 4.1-14.0) (p < 0.05). The most common reasons for consultation calls were chest pain (16%), trauma (15%), and abnormal laboratory or radiology results (14%). Of all calls, only 30% resulted in ambulance transport to the ED. On review of records, no adverse outcome or subsequent ambulance transport was identified. CONCLUSIONS The initiation of an on-call emergency physician program for after-hours consultation to jail nursing and law enforcement staff safely reduced ambulance transports from a county jail with no adverse outcomes identified.

Abstract
OBJECTIVE To investigate the potential impact for ambulance services of telephone assessment and triage for callers who present with non-serious problems (Category C calls) as classified by ambulance service call takers. DESIGN Pragmatic controlled trial. Calls identified using priority dispatch protocols as non-serious were allocated to intervention and control groups according to time of call. Ambulance dispatch occurred according to existing procedures. During intervention sessions, nurses or paramedics within the control room used a computerised decision support system to provide telephone assessment, triage and, if appropriate, offer advice to permit estimation of the potential impact on ambulance dispatch. SETTING Ambulance services in London and the West Midlands. SUBJECTS Patients for whom emergency calls were made to the ambulance services between April 1998 and May 1999 during four hour sessions sampled across all days of the week between 0700 and 2300. MAIN OUTCOME MEASURES Triage decision, ambulance cancellation, attendance at an emergency department. RESULTS In total, there were 635 intervention calls and 611 controls. Of those in the intervention group, 330 (52.0%) were triaged as not requiring an emergency ambulance, and 119 (36.6%) of these did not attend an emergency department. This compares with 55 (18.1%) of those triaged by a nurse or paramedic as requiring an ambulance (odds ratio 2.62; 95% CI 1.78 to 3.85). Patients triaged as not requiring an emergency ambulance were less likely to be admitted to an inpatient bed (odds ratio 0.55; 95% CI 0.33 to 0.93), but even so 30 (9.2%) were admitted. Nurses were more likely than paramedics to triage calls into the groups classified as not requiring an ambulance. After controlling for age, case mix, time of day, day of week, season, and ambulance service, the results of a logistic regression analysis revealed that this difference was significant with an odds ratio for nurses:paramedics of 1.28 (95% CI 1.12 to 1.47). CONCLUSIONS The findings indicate that telephone assessment of Category C calls identifies patients who are less likely to require emergency department care and that this could have a significant impact on emergency ambulance dispatch rates. Nurses were more likely than paramedics to assess calls as requiring an alternative response to emergency ambulance despatch, but the extent to which this relates to aspects of training and professional perspective is unclear. However, consideration should be given to the acceptability, reliability, and cost consequences of this intervention before it can be recommended for full evaluation.

Abstract
OBJECTIVE To estimate the proportion of patients transported by emergency medical services (EMS) who do not need immediate emergency medical care. Secondary objectives were: 1) to evaluate the ability of paramedics to determine hich patients need immediate ambulance transport, and 2) to evaluate on-scene patient characteristics that may aid in developing an EMS transport protocol. METHODS A prospective cross-sectional study design was utilized to estimate the percentage of low-risk patients eligible for non-ambulance transport among 277 patients transported to an emergency department via ambulance. The EMS personnel prospectively rated each patient as to need for immediate ambulance transport. Physician raters, using predefined criteria, determined eligibility for non-ambulance transport. RESULTS There were 116 patients (59.2%, 95% CI = 53.4%-65.0%) who were not in need of immediate emergency medical care. Comparison of the EMS personnel's rating with the criterion-standard need for emergency treatment transport yielded a sensitivity of 22.1% (95% CI = 13.9%-30.2%) and a specificity of 80.5% (95%) CI = 72.5%-88.3%). Chief complaints of abdominal pain (OR = 2.94, 95% CI = 1.31-6.60) and administration of oxygen (OR = 2.13, 95% CI = 1.06-4.29) were independently associated with the need for ambulance transport, while young age (OR = 0.28, 95% CI = 0.09-0.90) was negatively associated. CONCLUSIONS The majority of patients triaged as low-risk were not in need of immediate ambulance transport for emergency medical care. However, EMS personnel, unaided by triage protocols or specific training, could not reliably identify those patients in need of emergency medical treatment, and few factors were identified to assist that decision.

Abstract
OBJECTIVE To describe the scale and range of acute medical problems among patients who present to an inner city accident and emergency (A&E) department after attending nightclubs in Liverpool. METHODS From April 1997 to April 1998, all patients identified as having attended a nightclub before their arrival at the department were included in the study. Information regarding their attendance was gathered retrospectively using a standard proforma. SETTING A large, city centre, teaching hospital A&E department with an annual new patient attendance rate of over 95,000. RESULT 777 such patients were enrolled in the study (0.81% of all new attendances during the same period). This was probably an underestimate, as some eligible patients were not identified during the study. Predictably, most presentations were at the weekend between midnight and 08.00. Surprisingly, the commonest mode of transport to the hospital was an ambulance (38%, 298 of the total). Assault accounted for most presentations (57%, 443 of the total) and lacerations were the commonest injury (the face being most frequently affected). Alcohol was the commonest intoxicant overtly associated with the A&E department attendance. CONCLUSIONS Injury after assault is the commonest precipitant of hospital care among clubbers in Liverpool. Alcohol is the most important contributory factor, although illegal drug misuse is a considerable challenge in the clubs themselves. A number of measures such as (a) the introduction of unbreakable glass or plastic containers; (b) the elimination of glass from outside clubs; (c) the provision of high quality immediate medical care at larger venues; (d) the curbing of over crowding and cheap drinks promotions; (e) registration of doormen, and (f) targeted policing of the areas around nightclubs are urgently required to reduce the healthcare (and civic) burden of clubbing. The cost for these should be borne by the highly profitable clubbing and brewing industries. A national code of practice for clubs-already in existence voluntarily-should be made mandatory.

Abstract
OBJECTIVES To determine whether paramedics can safely decide which patients do not require ambulance transport or emergency department (ED) care. METHODS This was a prospective survey and linked medical record review. Paramedics completed a brief questionnaire for each patient they transported to a university hospital ED during a one-month period. A faculty emergency physician masked to the survey results reviewed hospital records. Ambulance transport was defined as "needed" if the charted differential diagnosis included diagnoses that could necessitate treatment in an ambulance. ED care was defined as "needed" if treatment of these diagnoses would necessitate resources not available in local urgent care centers (UCCs). RESULTS Two hundred thirty-six patients were transported; 183 corresponding ED charts were found. Agreement between paramedics and need determined by ED chart review was low for both transport method [kappa (kappa) = 0.47, 95% confidence interval (95% CI) = 0.34-0.60] and ED care (kappa = 0.32, 95% CI = 0.17-0.46). Paramedics recommended alternative transport for 97 patients, 23 of whom needed ambulance transport. Paramedics recommended non-ED care for 71 patients, 32 of whom needed ED care. CONCLUSION Paramedics cannot safely determine which patients do not need ambulance transport or ED care.

Abstract
OBJECTIVE To determine predicted utilization, decrease in ambulance transports, and target population for emergency medical services (EMS) if telemedicine capabilities were available to the medic units in the field. METHODS A retrospective chart review of 345 consecutive ambulance transports to four hospitals (Level I urban trauma center, urban tertiary care center, children's hospital and suburban community hospital) was performed by a panel of three board-certified emergency medicine physicians experienced and credentialed in emergency telemedicine. They independently reviewed the emergency department (ED) and EMS records and were asked to determine whether patients required ambulance transport for evaluation or whether disposition could be made following paramedic and emergency physician assessment via telemedicine. A five-point Likert scale was used to grade feasibility of telemedicine disposition (definitely yes, probably yes, maybe, probably no, definitely no). Other variables analyzed included age, sex, race, chief complaint, phone, private medical doctor, and call location by patient zip code, call site, and receiving hospital. RESULTS In 14.7% of cases (6% definitely yes and 8.7% probably yes), disposition could be made without transport using telemedicine. The age range for eliminating transport was 2 weeks through 92 years, with mean age of 26.6 years. Under the age of 50 years, 46 out of 238 patients (19.3%) could have possibly been managed by telemedicine. CONCLUSION Use of EMS telemedicine could result in an approximately 15% decrease in ambulance transports when it alone is added to the prehospital care provider's armamentarium. Emphasis for implementation should be placed on younger patients and an identified subset of chief complaints conducive to management using telemedicine.
