Introduction

Chronic Obstructive Pulmonary Disease (COPD) is an important and increasing cause of morbidity and mortality worldwide. Patients with COPD suffer from acute exacerbations (AE), which lead to a reduced quality of life, increased risk of mortality, further and longer hospitalization, and increased healthcare costs.

Objectives

The aims of the study are to describe patients with AE admitted through the Mobile Emergency Care Unit (MECU), to identify prognostic factors and to determine the associated 30-day mortality.

Methods

The study was performed in the MECU in Odense Denmark, from the 1st of July 2011 - 31st of December 2013. All first-time contact patients (>18years) with COPD treated by the MECU within this period were eligible for the study. AE diagnosis were confirmed by patient record review otherwise the patient was excluded from the study.

Results

Within the study period of 2 years and 5 months, 438 patients with AE were treated by the MECU, hereof 264 (60.3%) patients were first-time contacts, and thus eligible for inclusion in the study. Furthermore, the MECU had 174 (39.7%) additional patient contacts with AE within the study period. Of the 264 included first-time contacts, 113 (42.8%) were male, and the mean age was 72.4 years. 159 (60.2%) had severely affected breathing upon arrival of the MECU. 7 patients (2.6%) were intubated in the prehospital setting. 262 (99.2%) of all patients with AE in contact with the MECU were admitted to hospital, and only 2 (0.76%) patients were left at scene, this might be due to the fact that only first-time contacts were included in the study. Patients were hospitalized on average 5.3 days (0-48). 22 of 264 (8.3%) patients were transferred to the intensive care unit (ICU) with an average stay of 2.6 days (56.6 hours), of these 22 patients, 21 (95.5%) were mechanically ventilated on average 38.7 hours. 7/22 (31.8%) of patients admitted to ICU were dead within 30 days. The overall 30-day mortality among patients with AE was 12.5% (33/264). In a multivariate Cox regression model, age>80 years HR 0.8 (0.2-3.0) and female sex HR 0.8 (0.4-1.9) were analyzed as prognostic factors of mortality among patients with AE, however were found non-significant at a 95% confidence level.

Conclusions

We found that among first-time contact patients with AE treated by the MECU, a small proportion of these patients are admitted to ICU to receive mechanical ventilation. However one third of these patients die within 30 days. Despite non-significant levels, data indicate that when admitted to hospital due to AE, being male sex and of younger age worsens the prognosis.
