Does the prehospital National Early Warning Score predict the short-term mortality of unselected emergency patients?

Objectives: The prehospital research field has focused on studying patient survival in cardiac arrest, as well as acute coronary syndrome, stroke, and trauma. There is little known about the overall short-term mortality and its predictability in unselected prehospital patients. This study examines whether a prehospital National Early Warning Score (NEWS) predicts 1-day and 30-day mortalities. Methods: Data from all emergency medical service (EMS) situations were coupled to the mortality data obtained from the Causes of Death Registry during a six-month period in Northern Finland. NEWS values were calculated from first clinical parameters obtained on the scene and patients were categorized to the low, medium and high-risk groups accordingly. Sensitivities, specificities, positive predictive values (PPVs), negative predictive values (NPVs), and likelihood ratios (PLRs and NLRs) were calculated for 1-day and 30-day mortalities at the cut-off risks. Results: A total of 12,426 EMS calls were included in the study. The overall 1-day and 30-day mortalities were 1.5 and 4.3%, respectively. The 1-day mortality rate for NEWS values = 13 higher than 20%. The high-risk NEWS group had sensitivities for 1-day and 30-day mortalities 0.801 (CI 0.74-0.86) and 0.42 (CI 0.38-0.47), respectively. Conclusion: In prehospital environment, the high risk NEWS category was associated with 1-day mortality well above that of the medium and low risk NEWS categories. This effect was not as noticeable for 30-day mortality. The prehospital NEWS may be useful tool for recognising patients at early risk of death, allowing earlier interventions and responds to these patients.Peer reviewe

Medical priority dispatch codes-comparison with National Early Warning Score

Background: In Finland, calls for emergency medical services are prioritized by educated non-medical personnel into four categories-from A (highest risk) to D (lowest risk)-following a criteria-based national dispatch protocol. Discrepancies in triage may result in risk overestimation, leading to inappropriate use of emergency medical services units and to risk underestimation that can negatively impact patient outcome. To evaluate dispatch protocol accuracy, we assessed association between priority assigned at dispatch and the patient's condition assessed by emergency medical services on the scene using an early warning risk assessment tool. Methods: Using medical charts, clinical variables were prospectively recorded and evaluated for all emergency medical services missions in two hospital districts in Northern Finland during 1.1.2014-30.6.2014. Risk assessment was then re-categorized as low, medium, or high by calculating the National Early Warning Score (NEWS) based on the patients' clinical variables measured at the scene. Results: A total of 12,729 emergency medical services missions were evaluated, of which 616 (4.8%) were prioritized as A, 3193 (25.1%) as B, 5637 (44.3%) as C, and 3283 (25.8%) as D. Overall, 67.5% of the dispatch missions were correctly estimated according to NEWS. Of the highest dispatch priority missions A and B, 76.9 and 78.3%, respectively, were overestimated. Of the low urgency missions (C and D), 10.7% were underestimated; 32.0% of the patients who were assigned NEWS indicating high risk had initially been classified as low urgency C or D priorities at the dispatch. Discussion and conclusion: The present results show that the current Finnish medical dispatch protocol is suboptimal and needs to be further developed. A substantial proportion of EMS missions assessed as highest priority were categorized as lower risk according to the NEWS determined at the scene, indicating over-triage with the protocol. On the other hand, only a quarter of the high risk NEWS patients were classified as the highest priority at dispatch, indicating considerable under-triage with the protocol.Peer reviewe

EuReCa ONE—27 Nations, ONE Europe, ONE Registry A prospective one month analysis of out-of-hospital cardiac arrest outcomes in 27 countries in Europe

AbstractIntroductionThe aim of the EuReCa ONE study was to determine the incidence, process, and outcome for out of hospital cardiac arrest (OHCA) throughout Europe.MethodsThis was an international, prospective, multi-centre one-month study. Patients who suffered an OHCA during October 2014 who were attended and/or treated by an Emergency Medical Service (EMS) were eligible for inclusion in the study. Data were extracted from national, regional or local registries.ResultsData on 10,682 confirmed OHCAs from 248 regions in 27 countries, covering an estimated population of 174 million. In 7146 (66%) cases, CPR was started by a bystander or by the EMS. The incidence of CPR attempts ranged from 19.0 to 104.0 per 100,000 population per year. 1735 had ROSC on arrival at hospital (25.2%), Overall, 662/6414 (10.3%) in all cases with CPR attempted survived for at least 30 days or to hospital discharge.ConclusionThe results of EuReCa ONE highlight that OHCA is still a major public health problem accounting for a substantial number of deaths in Europe.EuReCa ONE very clearly demonstrates marked differences in the processes for data collection and reported outcomes following OHCA all over Europe. Using these data and analyses, different countries, regions, systems, and concepts can benchmark themselves and may learn from each other to further improve survival following one of our major health care events

Prehospital risk assessment and patient outcome:a population based study in Northern Finland

Abstract Emergency medical services (EMS) are designed to provide prompt response, on-scene treatment and transport for definitive care in patients with acute illness or injury. In recent years, the growing number of missions for non-urgent matters has challenged emergency care to design risk assessment protocols and tools to support decision-making and resource management at both dispatch and on-scene. The present study was designed to examine the efficacy of a criteria based dispatch protocol and National Early Warning Score (NEWS) in the Finnish EMS system. In addition, the aim of the research was to obtain data on patient allocation and mortality in the Northern Finnish population. The study data included 13,354 EMS missions from a six-month cohort (1.1.2014 - 30.6.2014) of prehospital emergency patients in two hospital districts – Kainuu and Länsi-Pohja – in Northern Finland, using a retrospective, observational design. Prehospital data including patient clinical physiological variables were combined with the national Finnish registries (Care Registry for Health Care, Intensive Care Consortium Database and Cause of Death Registry) in order to examine risk assessment in EMS and prehospital patient outcomes. Based on the result, the risk assessment at the dispatch was correct in 67.5% of the cases and four out of ten EMS missions did not lead to transportation by an ambulance. The use of the Finnish dispatch protocol resulted in an overall rate of 23% of over-triage and a 9% rate of under-triage. The highest NEWS category showed a good sensitivity for 1-day mortality but failed to adequately discriminate patients in need of intensive care or who died within 30-days in a large, unselected, typical EMS population. In conclusion, the criteria based dispatch protocol resulted in over-triage of a quarter of missions and in a significant rate of EMS missions without ambulance transportation. In addition, the predictive value of prehospital NEWS regarding the patient´s risk of death and need for intensive care was low.Tiivistelmä Ensihoitopalvelu on suunniteltu tarjoamaan nopeaa vastetta, paikalla tapahtuvaa hoitoa ja kuljetusta lopulliseen hoitopaikkaan potilaille, joilla on akuutti sairaus tai vamma. Viime vuosien lisääntyneet yhteydenotot ei-kiireellisissä asioissa on johtanut riskinarviotyökalujen kehittämiseen tukemaan päätöksentekoa ja resurssienhallintaa hätäpuhelun aikana ja tapahtumapaikalla. Tässä tutkimuksessa tarkasteltiin kriteeripohjaista hätäpuhelun käsittelyä sekä varhaisen varoituspistejärjestelmän (NEWS) tehokkuutta suomalaisessa ensihoitojärjestelmässä. Lisäksi tutkimuksen tavoitteena oli saada tietoa ensihoitopotilaiden hoitotuloksista ja kuolleisuudesta Pohjois-Suomessa. Tutkimukseen sisältyi 13 354 ensihoitotehtävää kuuden kuukauden kohortista (1.1.2014 – 30.6.2014) kahden sairaanhoitopiirin alueelta – Kainuu ja Länsi-Pohja – Pohjois-Suomessa käyttämällä retrospektiivistä havainnoivaa tutkimusmenetelmää. Ensihoidon aikana kerätty tieto, mukaan lukien potilaan kliiniset fysiologiset arvot, yhdistettiin kansallisiin rekistereihin (hoitoilmoitusrekisteri, tehohoitokonsortion laatutietokanta sekä kuolinsyyrekisteri) jotta ensihoitopotilaiden riskinarviota ja hoitotuloksia voitiin tutkia. Tutkimustulosten mukaan 67.5 prosentissa tapauksista riskinarvio hätäkeskuksessa oli oikea ja neljä kymmenestä ensihoitotehtävästä ei johtanut kuljetukseen ambulanssilla. Suomalaisen hälytysprotokollan käyttö johti yliarviointiin 23 prosentissa tapauksista ja aliarviointiin 9 prosentissa tapauksista. Korkeariskin NEWS-luokan herkkyys 1-päivän kuolleisuudelle oli hyvä, mutta se ei kyennyt erottelemaan riittävän hyvin potilaita, jotka tarvitsivat tehohoitoa tai kuolivat 30 päivän sisällä suuressa ei-valikoidussa tyypillisessä ensihoitopotilasväestössä. Yhteenvetona todettiin, että kriteeripohjaisen riskinarvion käyttö johti yliarvioon neljänneksestä tapauksista sekä huomattavaan ensihoitotehtävämäärään ilman ambulanssikuljetusta. Lisäksi ensihoidon aikana käytetyn varhaisen varoituspistejärjestelmän ennusteellinen arvo potilaan kuolemanriskin ja tehohoidon tarpeeseen oli matala

Ensihoidon kiireettömien tehtävien siirto puhelimessa tehtävään hoidontarpeen arviointiin : kuvaus resurssien käytöstä ja kustannusten jakaantumisesta

Tutkimuksen tarkoitus: Kuvata sairaanhoitajan puhelimessa toteuttaman hoidon tarpeen arvioinnin (PHTA) resurssien käyttöä ja kustannuksia ja verrata niitä ensihoidon resurssien käyttöön ja kustannuksiin. Aineisto ja menetelmät: Ensihoidon kiireettömien tehtävien määrät ja kestot kerättiin ensihoidon tietojärjestelmistä. Ensihoidon ja PHTA:n kustannukset kerättiin talousarvioista vuodelta 2018 Kainuussa ja Oulussa. Aineistosta laskettiin teoreettiset ensihoidon ja PHTA:n vuosikustannukset ja resurssien käyttö Kainuussa. Laskelmien avulla mallinnettiin Ouluun vastaavat kustannukset sekä teoreettiset säästöt. Tulokset: Vuonna 2018 Kainuussa ensihoidon kiireettömiä tehtäviä oli 5295 ja Oulussa 8598. Laskennallinen kiireettömän ensihoitotehtävän hinta oli Kainuussa 172,80€ ja Oulussa 102,70€, sekä yhden tehtävän käsittelyn hinta PHTA:lla hinta oli 7€. Ensihoitopalveluun integroidun PHTA:n tuomat teoreettiset säästöt ovat Oulussa ja Kainuussa 258 199–294 912€/vuosi. Henkilöstöresurssitarpeen väheneminen on yli 5000 tuntia vuodessa. Päätelmät: PHTA:n integroiminen ensihoitopalveluun voi tuottaa säästöjä ja hillitä ensihoidon tehtävämäärien nousua. Vapautuvat ensihoidon resurssit voitaisiin kohdentaa kiireellisten potilaiden hoitoon. PHTA:n käyttöönotto olisi mahdollista nykyisillä palvelurakenteilla

A high proportion of prehospital emergency patients are not transported by ambulance:a retrospective cohort study in Northern Finland

Abstract Background: The number of missions in the emergency medical services (EMS) has increased considerably in recent years. People are requesting ambulance for even minor illnesses and non‐medical problems, which is placing financial and resource burdens on the EMS. The aim of this study was to determine the rate of non‐transportation missions in Northern Finland and the reasons for these missions. Methods: All ambulance missions in two hospital districts in Northern Finland during the 6‐month period of January 1 through June 30, 2014, were retrospectively evaluated from the EMS charts to identify missions in which the patients were not transported by the EMS. The non‐transportation rates and reasons were calculated and expressed as percentages. Results: In 41.7% of the 13,354 missions, the patient was not transported from the scene by an ambulance. After a medical assessment and care was provided by the EMS, 48.2% of these non‐transport patients were evaluated as not needing further treatment in the emergency department and were directed to contact the municipal health care center during office hours. There was no need for any medical care in 39.9% of non‐transportation missions. Conclusion: This study showed a high rate of EMS missions resulting in non‐transportation in two hospital districts in Northern Finland. In the majority of these missions there was no need for emergency admission to an emergency department or for any medical care at all. These findings indicate that an improvement in the dispatch process and primary care resources might be of benefit
