Abstract part 1 Acute exacerbations of chronic obstructive pulmonary disease (AECOPDs) frequently cause patients with COPD to access the emergency department and have a negative impact on the course of the disease. The objectives of our study were: 1) describing the socio-demographic and clinical characteristics, and the clinical management, of patients with AECOPD, when they present to the emergency department; and 2) estimating the costs related to the management of these patients. We conducted a retrospective cohort study in Italy, collecting data on 4,396 patients, from 34 centres. Patients had a mean (SD) age of 76,6 (10.6) years, and 61.2 % of them where males. More than 70 % of the patients had a moderate to very high comorbidity burden, and heart failure was present in 26.4 % of the cohort. The 64.6 % of patients were admitted to hospital wards, with a mean (SD) length of stay of 10.8 (9.8) days. The estimated cost per patient was 2617 €. Conclusions: Patients attending the ED for an AECOPD are old and present important comorbidities. The rate of admission is high, and costs are remarkable. Abstract part 2 Exacerbations of chronic obstructive pulmonary disease (AECOPD) frequently require hospitalizations, may necessitate of invasive mechanical ventilation (IMV), and are associated with a remarkable in-hospital mortality. The BAP-65 score is a risk assessment model (RAM) based on simple variables, that has been proposed for the prediction of these adverse outcomes in patients with AECOPD. If showed to be accurate, the BAP-65 RAM might be used to guide the patients management, in terms of destination and treatment. We conducted a retrospective, multicentre, chart-review study, on patients attending the ED for an AECOPD during 2014. The aim of the study was the validation of the BAP-65 RAM for the prediction of in-hospital death or use of IMV (composite primary outcome). We assessed the discrimination and the prognostic performance of the BAP-65 RAM. We enrolled 2908 patients from 20 centres across Italy. The mean (standard deviation) age was 76 (11) years, and 38% of patients were female. The composite outcome occurred in 5.3% of patients. The AUROC of BAP-65 for the composite outcome was 0.64 (95%CI 0.59-0.68). The sensitivity of BAP-65 score ≥ 4 to predict in-hospital mortality was 44% (95% CI 34%-55%), the specificity was 84% (95% CI 82%-85%), the positive predictive value was 9% (95% CI 6%-12%), and the negative predictive value was 98% (95% CI 97%-98%). Conclusions: In patients attending Italian EDs with an AECOPD, we found that the BAP-65 score did not have sufficient accuracy to stratify patients upon their risk of severe in-hospital outcomes.

Sintesi in lingua italiana – Parte prima Nei pazienti con BPCO, le riacutizzazioni sono una frequente causa di accesso in pronto soccorso e possono condizionarne negativamente la prognosi. Obiettivi dello studio erano: 1) descrivere le caratteristiche socio-demografiche e cliniche, nonché la gestione in pronto soccorso dei pazienti con riacutizzazione di bronco-pneumopatia ostruttiva cronica (BPCO); 2) stimarne i costi. Abbiamo condotto uno studio di coorte retrospettivo in Italia, raccogliendo dati su 4,396 pazienti da 34 centri. I pazienti avevano un’età media (deviazione standard [DS]) di 77 (11) anni, ed erano femmine nel 39% dei casi. Oltre il 70% dei pazienti presentava un indice di comorbidità moderato o severo, e nel 26% dei casi era presenta anche una diagnosi di scompenso cardiaco. Il 65% dei pazienti è stato ospedalizzato, per una durata media (DS) di 11 (10) giorni. Il costo stimato per paziente è 2.617 €. In conclusione, I pazienti che afferiscono in pronto soccorso con una riacutizzazione di BPCO sono anziani e gravate da importanti comorbidità. Il tasso di ricovero in questi pazienti è alto, e i costi onerosi. Sintesi in lingua italiana – Parte seconda Le riacutizzazioni di BPCO esitano frequentemente in ospedalizzazione, possono richiedere il trattamento con ventilazione invasiva e sono associate a elevata mortalità intraospedaliera. Il BAP-65 è modello di predizione del rischio di eventi avversi per pazienti con riacutizzazione di BPCO. Il BAP-65 è semplice da utilizzare e, se la sua accuratezza prognostica fosse confermata, potrebbe essere utilizzato per guidare la gestione dei pazienti. Abbiamo condotto uno studio retrospettivo, multicentrico in pazienti che afferivano in pronto soccorso per una riacutizzazione di BPCO durante il 2014. Lo scopo dello studio era validare il modello BAP-65 per la predizione dell’outcome combinato mortalità intraospedaliera e ricorso alla ventilazione invasiva. Abbiamo arruolato 2.908 pazienti da 20 centri Italiani. L’età media (DS) era 76 (11) anni, e il 38% dei pazienti era femmina. L’outcome combinato si è verificato nel 5% dei pazienti. L’area sotto la curva (AUROC) stimata per l’outcome combinato è risultata pari a 0,64 (95%CI 0,59-0,68). Un punteggio BAP-65 ≥ 4 ha mostrato una sensibilità pari a 44% (95% CI 34%-55%) nel predire la mortalità intraospedaliera, con specificità 84% (95% CI 82%-85%), valore predittivo positivo 9% (95% CI 6%-12%) e valore predittivo negativo 98% (95% CI 97%-98%). In conclusione, il modello BAP-65 non ha dimostrato accuratezza sufficiente per un’efficacie stratificazione del rischio di prognosi infausta nella popolazione studiata.
