Introduction: Triage process in the emergency department aims to re-organize the time demands in treating patients, allowing a faster access to care for those patients who actually have the need of an emergency treatment. The proper color code assignment, using procedures and protocols, could be influenced by the inter-operator variability. For this reason, the use of scores with predictive performance on hospitalization could help nurses in triage. Among these scores, the Modified Early Warning Score (MEWS) seems to be promising. Aim: To describe the predictive performance of MEWS at the triage in emergency department on (a) hospitalization and (b) hospitalization in intensive care units. Materials and methods: Pilot study with a monocentric descriptive design, using a consecutive sampling of adult patients having a surgical or medical condition. Enrollment has been conducted between July and August 2018. Results: In this study, 145 patients were included from a single emergency department in the north of Italy. MEWS was higher in hospitalized patients than the discharged ones (P-Value<0,001), being also higher in patients hospitalized in intensive care units than the ones hospitalized in ordinary wards (P-Value<0,001). The odds of hospitalization increases of roughly three time for each additional point of MEWS (OR=3,103; IC95%=2,145-4,49; P-Value=0,000). The odds of hospitalization in intensive care unit increases of roughly four times for each additional point of MEWS (OR= 3,955; IC95%=1,744-8,359; P-Value= 0,001). Conclusions: MEWS used in the emergency department (at triage) seems to be predictive of hospitalization and intensive care hospitalization. However, further larger studies are needed to better understand the performance of MEWS on discriminating hospitalization. This pilot study pro- vides useful information to allow precise designing of further studies.
Introduzione: il triage è un processo organizzativo volto a ridistribuire i tempi di attesa d’accesso alle prestazioni sanitarie a favore di chi ha necessità d’interventi in emergenza e urgenza. La corretta attribuzione del codice di triage, anche in presenza di procedure e protocolli condivisi, non è priva di variabilità operatore dipendente. Per questi motivi, gli score con valenza predittiva di ospedaliz- zazione riescono a supportare le valutazioni del professionista in triage. Tra questi score inizia ad emergere il possibile utilizzo del Modified Early Warning Score (MEWS). Scopo: Descrivere le caratteristiche di predittività dello score MEWS utilizzato al triage in pronto soccorso (PS) (a) sul ricovero ospedaliero in ge- nerale, ed in particolare (b) sul ricovero ospedaliero in ambiente intensivo. Materiali e metodi: Studio pilota descrittivo monocentrico con campionamento consecutivo di pazienti maggiorenni con patologia medica o chirurgica. L’arruolamento è stato condotto tra luglio e agosto 2018. Risultati: Sono stati arruolati 145 pazienti in un unico PS del nord Italia. Lo score MEWS ha mostrato punteggi più elevati sia nei pazienti rico- verati versus i pazienti dimessi (P-Value<0,001), sia nei pazienti ricoverati in ambiente intensivo versus i ricoverati in degenza ordinaria (P-Va- lue<0,001). La probabilità del ricovero aumenta di circa tre volte all’aumentare di ogni punto dello score MEWS (OR=3,103; IC95%=2,145-4,49; P-Value=0,000). La probabilità di ricovero in ambiente intensivo aumenta di quasi quattro volte all’aumentare di ogni punto sullo score MEWS (OR= 3,955; IC95%=1,744-8,359; P-Value=0,001). Conclusioni: Lo score MEWS mostra un ruolo predittivo sia sul ricovero in generale sia sul ricovero in ambiente intensivo. Tuttavia, ulteriori indagini su ampia scala e che aggiustino gli effetti dello score MEWS sul ricovero sono necessari per comprenderne la performance predittiva. Questo studio pilota fornisce le informazioni necessarie per pianificare indagini maggiormente robuste.
