ABSTRACT
Police calls for service are an important conduit by which officers and researchers can obtain insight into public requests for police service. Questions remain, however, about the quality of these data, and, particularly, the prevalence of measurement error in the classifications of events. As part of the present research, we assess the accuracy of call-types used by police dispatchers to describe events that are responded to by police officers. Drawing upon a sample of 515,155 calls for police service, we explore the differences among initial call-types, cleared call-types, and crime-types as documented in crime reports. Our analyses reveal that although the majority of calls for service exhibit overlap in their classifications, many still exhibit evidence of misclassification. Our analyses also reveal that such patterns vary as a function of call- and crime-type categories. We discuss our findings in light of the challenges of the classification process and the associated implications.

Emergency medical services (EMS) activation is an integral component in managing individuals with myocardial infarction (MI). EMS play a crucial role in early MI symptom recognition, prompt transport to percutaneous coronary intervention centres and timely administration of management. The objective of this study was to examine sex differences in prehospital EMS care of patients hospitalized with Ml using data from a retrospective population-based cohort study of linked health administrative data for people with a hospital diagnosis of MI in Australia (2001-18).

In recent years, the impact of new major infectious diseases on people's normal life is becoming more and more frequent, which has brought great impact on people's life safety and social economy, especially the corona virus disease 2019, which has been sweeping the globe. Public health and disease prevention and control systems in different countries have different performances in response to the pandemic, but they all have exposed many shortcomings. Countries around the world urgently need to improve the monitoring, early warning and emergency response systems for new major infectious diseases. As the outpost and main part of medical rescue, the hospital urgently needs to establish a set of scientifically advanced emergency response mechanism that is suitable for the business process of the medical system and unified standards in order to improve the response efficiency and quality of emergency treatment.

OBJECTIVE: To determine the inter-rater reliability and validity of the Netherlands Triage Standard (NTS) for paediatric triage. DESIGN: A cross-sectional study using fictional cases for telephone and physical triage. METHOD: An expert panel established in advance the urgency of 40 cases concerning emergency help requests from non-referred children (the reference standard). These requests were presented in an online survey to triagists from three general practitioner (GP) out-of-hours practices, three ambulance dispatching centres and three hospital emergency departments. Triagists assessed all cases, using the NTS. We determined the agreement on degrees of urgency between different triagists and compared them with the reference standard. The outcome measure for inter-rater reliability was the intraclass correlation coefficient (ICC). The outcome measures for validity were the degree of agreement with the reference standard, under-triage and over-triage, and sensitivity and specificity in identifying high-urgency (U0-U2) versus low-urgency cases (U30U5). RESULTS: In total, 116 triagists participated in the study (response: 86%). The ICC was 0.73 among all triagists, and was highest in the out-of-hours GP cooperatives. There was 62.3% agreement with the reference standard, 17.4% under-triage and 20.2% over-triage. Of the divergent urgencies, 77% differed by only one urgency category. The sensitivity was 85.2% and the specificity 89.7%. The sensitivity and specificity of triage by the GP out-of-hours practices (82.7% and 92.7%, respectively) were almost the same as that by the hospital emergency departments (79.6% and 92.5%, respectively). Triage by the ambulance dispatching centres had relatively high sensitivity (93%), but relatively low specificity (82.4%). CONCLUSION: The results of the study contribute to the evidence that the NTS is a reliable and valid triage standard for paediatric patients. The urgency assessments by triagists in the GP out-of-hours practices, ambulance dispatching centres and hospital emergency departments were broadly in agreement. Results were limited by cases being on paper and triage only on anamnestic characteristics.

OBJECTIVES: This study aimed to assess whether trigger tools were useful identifying triage errors among patients referred to non-emergency care by emergency medical dispatch nurses, and to describe the characteristics of these patients. DESIGN: An observational study of patients referred by dispatch nurses to non-emergency care. SETTING: Dispatch centres in two Swedish regions. PARTICIPANTS: A total of 1089 adult patients directed to non-emergency care by dispatch nurses between October 2016 and February 2017. 53% were female and the median age was 61 years. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was a visit to an emergency department within 7 days of contact with the dispatch centre. Secondary outcomes were (1) visits related to the primary contact with the dispatch centre, (2) provision of care above the primary level (ie, interventions not available at a typical local primary care centre) and (3) admission to hospital in-patient care. RESULTS: Of 1089 included patients, 260 (24%) visited an emergency department within 7 days. Of these, 209 (80%) were related to the dispatch centre contact, 143 (55%) received interventions above the primary care level and 99 (38%) were admitted to in-patient care. Elderly (65+) patients (OR 1.45, 95% CI 1.05 to 1.98) and patients referred onwards to other healthcare providers (OR 1.58, 95% CI 1.15 to 2.19) had higher likelihoods of visiting an emergency department. Six avoidable patient harms were identified, none of which were captured by existing incident reporting systems, and all of which would have received an ambulance if the decision support system had been strictly adhered to. CONCLUSION: The use of these patient outcomes in the framework of a Global Trigger Tool-based review can identify patient harms missed by incident reporting systems in the context of emergency medical dispatching. Increased compliance with the decision support system has the potential to improve patient safety.

BACKGROUND: Dispatch services (DS's) form an integral part of emergency medical service (EMS) systems. The role of a dispatcher has also evolved into a crucial link in patient care delivery, particularly in dispatcher assisted cardio-pulmonary resuscitation (DACPR) during out-of-hospital cardiac arrest (OHCA). Yet, there has been a paucity of research into the emerging area of dispatch science in Asia. This paper compares the characteristics of DS's, and state of implementation of DACPR within the Pan-Asian Resuscitation Outcomes (PAROS) network. METHODS: A cross-sectional descriptive survey addressing population characteristics, DS structures and levels of service, state of DACPR implementation (including protocols and quality improvement programs) among PAROS DS's. RESULTS: 9 DS's responded, representing a total of 23 dispatch centres from 9 countries that serve over 80 million people. Most PAROS DS's operate a tiered dispatch response, have implemented medical oversight, and tend to be staffed by dispatchers with a predominantly medical background. Almost all PAROS DS's have begun tracking key EMS indicators. 77.8% (n = 7) of PAROS DS's have introduced DACPR. Of the DS's that have rolled out DACPR, 71.4% (n = 5) provided instructions in over one language. All DS's that implemented DACPR and provided feedback to dispatchers offered feedback on missed OHCA recognition. The majority of DS's (83.3%; n = 5) that offered DACPR and provided feedback to dispatchers also implemented corrective feedback, while 66.7% (n = 4) offered positive feedback. Compression-only CPR was the standard instruction for PAROS DS's. OHCA recognition sensitivity varied widely in PAROS DS's, ranging from 32.6% (95% CI: 29.9-35.5%) to 79.2% (95% CI: 72.9-84.4%). Median time to first compression ranged from 120 s to 220 s. CONCLUSIONS: We found notable variations in characteristics and state of DACPR implementation between PAROS DS's. These findings will lay the groundwork for future DS and DACPR studies in the PAROS network.

CONTEXT: Houston policy is to dual dispatch medically trained firefighters, in addition to emergency medical services (EMS) units to out-of-hospital cardiac arrest (OHCA) cases. While believed to improve public health outcomes, no research exists supporting the policy that when firefighters respond before a better-equipped EMS unit, they increase the probability of survival. OBJECTIVE: To inform EMS policy decisions regarding the effectiveness of dual dispatch by determining the impact of medically trained firefighter dispatch on return of spontaneous circulation (ROSC), a measure of survivability, in OHCA 911 calls while controlling for the subsequent arrival of an EMS unit. DESIGN: This retrospective study uses logistic regression to determine the association between ROSC and response time for fire apparatus first responders controlling for arrival of the EMS unit. SETTING: Out-of-hospital cardiac arrest cases in Houston between May 2008 and April 2013 when dual dispatch was used. PARTICIPANTS: A total of 6961 OHCA cases with the complete data needed for the analysis. MAIN OUTCOME MEASURES: Logistic regression of the dependence of OHCA survival using the indicator ROSC, as related to the fire first responder response times controlling for subsequent arrival of the EMS. RESULTS: Fire apparatus arrived first in 46.7% of cases, a median value of 1.5 minutes before an EMS unit. Controlling for subsequent arrival time of EMS has no effect on ROSC achieved by the fire first responder. If the firefighters had not responded, the resulting 1.5-minute increase in response time equates to a decrease in probability of attaining ROSC of 20.1% for cases regardless of presenting heart rhythm and a 47.7% decrease for ventricular fibrillation cases in which bystander cardiopulmonary resuscitation was initiated. CONCLUSIONS: The firefighter first responder not only improved response time but also greatly increased survivability independent of the arrival time of the better-equipped EMS unit, validating the public health benefit of the dual dispatch policy in Houston.

INTRODUCTION: When general practitioners (GPs) order an ambulance, their calls are handled by staff at the emergency medical dispatch centre (EMDC) who then select an appropriate response. There are currently no data evaluating this mode of communication between the GPs and the staff at the EMDC. â©METHODS: A retrospective study was performed based on evaluation of calls during which GPs requested a rapid response ambulance. Over a period of three months of 2014, 1,334 calls were included for evaluation according to specific parameters including a transactional analysis of the communication. â©RESULTS: We found problematic communication in less than 2% (n = 25) of the evaluated calls. In 68% of the 25 problematic cases transactional analysis showed that the staff at the EMDC initiated the problematic communication. In 4% (n = 51) of the calls, the GP delegated the call to a secretary or nurse, and we found that these calls were more likely to contain problematic communication (odds ratio = 5.1). In 18% (n = 236) of the cases, there was not sufficient information to assess if the physician-manned mobile emergency care unit (MECU) should have been dispatched along with the ambulance. â©CONCLUSIONS: Problematic communication is rare, occurring in less than 2% of the calls. Problems are more frequent when the GP delegates the call. Furthermore, we established that the communicative problems were more likely to be initiated by the staff at the EMDC than by the GP. In addition, we found that there was insufficient information to assess if the MECU should be dispatched in nearly 20% of all calls.â© FUNDING: none.â© TRIAL REGISTRATION: The study was approved by the Danish Data Protection Agency (ref. no. 2008-58-0035). Informed consent from individual patients or ethics committee approval was not required since it was a register-based study solely and no person-identifiable data were used.

BACKGROUND: An optimized protocol to help dispatchers identify potential cases of cardiac arrest and provide phone instructions for cardiopulmonary resuscitation (CPR) may increase the provision of bystander CPR, further improving the survival rate and neurological outcomes. OBJECTIVE: We assessed a revised dispatcher-assisted (DA)-CPR protocol with a continuous quality-improvement feature in a county fire department-based emergency medical services system. METHODS: This was a before-and-after intervention prospective study conducted in Taoyuan City, Taiwan. The participants were out-of-hospital cardiac arrest (OHCA) patients from November 2014 to February 2016. Interventional quality control started in August 2015. Approximately 10% of the telephone calls from these OHCA patients were reviewed. RESULTS: In total, 66 and 64 cases were included in the before- and after-intervention groups, respectively. No significant differences were observed in sex, age, day, and time of events, or languages spoken by the callers. After the intervention, we found significant improvements in the rates at which cardiac arrests were recognized (54.5% vs. 68.8%; p = 0.007) and normal breathing was checked (51.5% vs. 76.6%, p = 0.003). Moreover, the frequency with which DA-CPR was provided by the dispatchers improved significantly (50.0% vs. 72.7%; p = 0.046). Significant improvement in patient outcomes was observed with regard to 24-h survival (7.6% vs. 20.3%, p = 0.036) but not with regard to survival to discharge (3.0% vs. 10.9%, p = 0.076). CONCLUSIONS: The study found this DA-CPR protocol, which includes continuous quality control, is promising as it improved the successful recognition of cardiac arrests.

BACKGROUND: Dispatch centres (DCs) are considered an essential but expensive component of many highly developed healthcare systems. The number of DCs in a country, region, or state is usually based on local history and often related to highly decentralised healthcare systems. Today, current technology (Global Positioning System or Internet access) abolishes the need for closeness between DCs and the population. Switzerland went from 22 DCs in 2006 to 17 today. This study describes from a quality and patient safety point of view the merger of two DCs. METHODS: The study analysed the performance (over and under-triage) of two medical DCs for 12 months prior to merging and for 12 months again after the merger in 2015. Performance was measured comparing the priority level chosen by dispatcher and the severity of cases assessed by paramedics on site using the National Advisory Committee for Aeronautics (NACA) score. We ruled that NACA score > 3 (injuries/diseases which can possibly lead to deterioration of vital signs) to 7 (lethal injuries/diseases) should require a priority dispatch with lights and siren (L&S). While NACA score < 4 should require a priority dispatch without L&S. Over-triage was defined as the proportion of L&S dispatches with a NACA score < 4, and under-triage as the proportion of dispatches without L&S with a NACA > 3. RESULTS: Prior to merging, Dispatch A had a sensitivity/specificity regarding the use of lights and sirens and severity of cases of 86%/48% with over- and under-triage rates of 78% and 5%, respectively. Dispatch B had sensitivity and specificity of 92%/20% and over- and under-triage rates of 84% and 7%, respectively. After they merged, global sensitivity/specificity reached 87%/67%, and over- and under-triage rates were 71% and 3%, respectively CONCLUSIONS: A part the potential cost advantage achieved by the merger of two DCs, it can improve the quality of services to the population, reducing over- and under-triage and the use of lights and sirens and therefore, the risk of accidents. This is especially the case when a DC with poor triage performance merges with a high-performing DC.

BACKGROUND AND AIMS: We examined the accuracy in assessments of emergency dispatchers according to their education and time of the day. We examined this in chest pain patients who were diagnosed with a potentially life-threatening condition (LTC) or died within 30days. METHODS: Among 2205 persons, 482 died, 1631 experienced an acute coronary syndrome (ACS), 1914 had a LTC. Multivariable logistic regression was used to study how time of the call and the dispatcher's education were associated with the risk of missing to give priority 1 (the highest). RESULTS: Among patients who died, a 7-fold increase in odds of missing to give priority 1 was noted at 1.00pm, as compared with midnight. Compared with assistant nurses, odds ratio for dispatchers with no (medical) training was 0.34 (95% CI 0.14 to 0.77). Among patients with an ACS, odds ratio for calls arriving before lunch was 2.02 (95% CI 1.22 to 3.43), compared with midnight. Compared with assistant nurses, odds ratio for operators with no training was 0.23 (95% CI 0.13 to 0.40). Similar associations were noted for those with any LTC. Dispatcher's education was not associated with the patient's survival. CONCLUSIONS: In this group of patients, which experience substantial mortality and morbidity, the risk of not obtaining highest dispatch priority was increased up to 7-fold during lunchtime. Dispatch operators without medical education had the lowest risk, compared with nurses and assistant nurses, of missing to give priority 1, at the expense of lower positive predictive value. KEY MESSAGES: What is already known about this subject? Use of the emergency medical service (EMS) increases survival among patients with acute coronary syndromes. It is unknown whether the efficiency - as judged by the ability to identify life-threatening cases among patients with chest pain - varies according to the dispatcher's educational level and the time of day. What does this study add? We provide evidence that the dispatcher's education does not influence survival among patients calling the EMS due to chest discomfort. However, medically educated dispatchers are at greatest risk of missing to identify life-threatening cases, which is explained by more parsimonious use of the highest dispatch priority. We also show that the risk of missing life-threatening cases is at highest around lunch time. How might this impact on clinical practice? Dispatch centers are operated differently all over the world and chest discomfort is one of the most frequent symptoms encountered; we provide evidence that it is safe to operate a dispatch center without medically trained personnel, who actually miss fewer cases of acute coronary syndromes. However, non-medically trained dispatchers consume more pre-hospital resources.

BACKGROUND: Emergency dispatchers use protocols to instruct bystanders in cardiopulmonary resuscitation (CPR). Studies changing one element in the dispatcher's protocol report improved CPR quality. Whether several changes interact is unknown and the effect of combining multiple changes previously reported to improve CPR quality into one protocol remains to be investigated. We hypothesize that a novel dispatch protocol, combining multiple beneficial elements improves CPR quality compared with a standard protocol. METHODS: A novel dispatch protocol was designed including wording on chest compressions, using a metronome, regular encouragements and a 10-s rest each minute. In a simulated cardiac arrest scenario, laypersons were randomized to perform single-rescuer CPR guided with the novel or the standard protocol. PRIMARY OUTCOME: a composite endpoint of time to first compression, hand position, compression depth and rate and hands-off time (maximum score: 22 points). Afterwards participants answered a questionnaire evaluating the dispatcher assistance. RESULTS: The novel protocol (n=61) improved CPR quality score compared with the standard protocol (n=64) (mean (SD): 18.6 (1.4)) points vs. 17.5 (1.7) points, p<0.001. The novel protocol resulted in deeper chest compressions (mean (SD): 58 (12)mm vs. 52 (13)mm, p=0.02) and improved rate of correct hand position (61% vs. 36%, p=0.01) compared with the standard protocol. In both protocols hands-off time was short. The novel protocol improved motivation among rescuers compared with the standard protocol (p=0.002). CONCLUSIONS: Participants guided with a standard dispatch protocol performed high quality CPR. A novel bundle of care protocol improved CPR quality score and motivation among rescuers.

OBJECTIVE: In Denmark, calls to the Danish emergency number 1-1-2 concerning medical emergencies are received by an emergency medical communication center (EMCC). At the EMCC, health care professionals (nurses, paramedics, and physicians) decide the necessary response, depending on the level of emergency as indicated by the Danish Index for Emergency Care. The index states 37 main criteria (symptoms) and five levels of emergency, descending from A (life threatening) to E (not serious). An ambulance is not sent to emergency level-E patients (level-E patients), but they are given other kinds of help/advice. No prior studies focusing on Danish level-E patients exist, hence the sparse knowledge about them. This study aimed to characterize level-E patients in the Central Denmark Region and to investigate their progress in the health care system after the 1-1-2 call, regarding contacting 1-1-2 again, general practitioner and Emergency Department (ED) visits, hospital admission, and death. METHODS: This is a retrospective follow-up study of callers who contacted the EMCC of the Central Denmark Region and were assessed as level-E patients from August 2013 to July 2014. The study population was identified in the EMCC dispatch software, whose data were supplemented with health care data from three national registries. RESULTS: Of the 53,414 patients who called 1-1-2 over the study period, 4,962 level-E patients were included in the study. The median age was 47 years (IQR: 24.3-67.7), and 53.4% were men. The most common main criteria were extremity pain - minor wounds. Within 1 day after their 1-1-2 call, 42.1% had a subsequent contact with the health care system. Of those, 5.9% called 1-1-2 again, 24.3% contacted an ED, and 8.6% were admitted. The fatality rate was 0.1%. CONCLUSIONS: Level-E patients who contacted the EMCC of the Central Denmark Region were most frequently young adults. Almost 60% of level E-patients, who could be tracked, had no further contact with the health care system within a day after their 1-1-2 call. Of those who did, a quarter contacted an ED, indicating that level-E patients needed medical attention. The low fatality rates suggest limited undertriage, that is, level-E patients do not seem to need emergency medical service transportation. Further studies on undertriage among other things are needed.

BACKGROUND: The Emergency Medical Communication Centre (EMCC) operators in Norway report using the Norwegian Index for Medical Emergency Assistance (Index), a criteria-based dispatch guideline, in about 75 % of medical emergency calls. The main purpose of a dispatch guideline is to assist the operator in securing a correct response as quickly as possible. The effect of using the guideline on EMCC response interval is as yet unknown. We wanted to ascertain an objective measure of guideline adherence, and explore a possible effect on emergency medical dispatch (EMD) response interval. METHODS: Observational cross-sectional study based on digital telephone recordings and EMCC records; 299 random calls ending in acute and urgent responses from seven strategically selected EMCCs were included. Ability to confirm location and patient consciousness within an acceptable time interval and structural use of criteria cards were indicators used to create an overall guideline adherence variable. We then explored the relationship between different levels of guideline adherence and EMD response interval. RESULTS: The overall guideline adherence was 80 %. Location and patient consciousness were confirmed within 1 min in 83 % of the calls. The criteria cards were used systematically as intended in 64 % of the cases. Total median response interval was 2:28, with 2:01 for acute calls and 4:10 for urgent calls (p < 0.0005). Lower guideline adherence was associated with higher EMD response interval (p < 0.0005). CONCLUSION: The measured guideline adherence was higher than previously reported by the operators themselves. Patient consciousness was rapidly confirmed in the majority of cases. Failure to use Index criteria as intended result in delayed ambulance dispatch and a potential risk of undertriage.

BACKGROUND AND PURPOSE: There are no contemporary national-level data on Emergency Medical Services (EMS) response times for suspected stroke in the United States (US). Because effective stroke treatment is time-dependent, we characterized response times for suspected stroke, and examined whether they met guideline recommendations. METHODS: Using the National EMS Information System dataset, we included 911 calls for patients ≥ 18 years with an EMS provider impression of stroke. We examined variation in the total EMS response time by dispatch notification of stroke, age, sex, race, region, time of day, day of the week, as well as the proportion of EMS responses that met guideline recommended response times. Total EMS response time included call center dispatch time (receipt of call by dispatch to EMS being notified), EMS dispatch time (dispatch informing EMS to EMS starts moving), time to scene (EMS starts moving to EMS arrival on scene), time on scene (EMS arrival on scene to EMS leaving scene), and transport time (EMS leaving scene to reaching treatment facility). RESULTS: We identified 184,179 events with primary impressions of stroke (mean age 70.4 ± 16.4 years, 55% male). Median total EMS response time was 36 (IQR 28.7-48.0) minutes. Longer response times were observed for patients aged 65-74 years, of white race, females, and from non-urban areas. Dispatch identification of stroke versus "other" was associated with marginally faster response times (36.0 versus 36.7 minutes, p < 0.01). When compared to recommended guidelines, 78% of EMS responses met dispatch delay of <1 minute, 72% met time to scene of <8 minutes, and 46% met on-scene time of <15 minutes. CONCLUSIONS: In the United States, time from receipt of 9-1-1 calls to treatment center arrival takes a median of 36 minutes for stroke patients, an improvement upon previously published times. The fact that 22%-46% of EMS responses did not meet stroke guidelines highlights an opportunity for improvement. Future studies should examine EMS diagnostic accuracy nationally or regionally using outcomes based approaches, as accurate recognition of prehospital strokes is vital in order to improve response times, adhere to guidelines, and ultimately provide timely and effective stroke treatment.

BACKGROUND AND AIMS: From 2009 to 2010, approximately 14,000 consecutive persons who called for the EMS due to chest discomfort were registered. From the seventh month, dispatchers ask 2285 patient ten pre-specified questions. We evaluate which of these questions was independently able to predict an acute coronary syndrome (ACS), life-threatening condition (LTC) and death. METHODS: The questions asked mainly dealt with previous history and type of symptoms, each with yes/no answers. The dispatcher took a decision on priority; 1) immediately with sirens/blue light; 2) EMS on the scene within 30min; 3) normal waiting time.We examined the relationship between the answers to these questions and subsequent dispatch priority, as well as outcome, in terms of ACS, LTC and all-cause mortality. RESULTS: 2285 patients (mean age 67years, 49% women) took part, of which 12% had a final diagnosis of ACS and 15% had a LTC. There was a significant relationship between all the ten questions and the priority given by dispatchers. Localisation of the discomfort to the center of the chest, more intensive pain, history of angina or myocardial infarction as well as experience of cold sweat were the most important predictors when evaluating the probability of ACS and LTC. Not breathing normally and having diabetes were related to 30-day mortality. CONCLUSIONS: Among individuals, who call for the EMS due to chest discomfort, the intensity and the localisation of the pain, as well as a history of ischemic heart disease, appeared to be the most strongly associated with outcome.

This project aimed to develop a standard operating procedure (SOP) for suicide postvention in Fire Service. First, an existing SOP was refined through expert review. Next, focus groups were conducted with fire departments lacking a peer suicide postvention SOP; feedback obtained guided revisions. The current article describes the iterative process used to evaluate and revise a Suicide Postvention SOP into a Postvention guideline that is available for implementation and evaluation. Postventions assist survivors in grief and bereavement and attempt to prevent additional negative outcomes. The implementation of suicide postvention guidelines will increase behavioral wellness within Fire Service.
