A Scandinavian audit of hospitalizations for chronic obstructive pulmonary disease

SummaryIn Scandinavia no large audits of hospitalizations for chronic obstructive pulmonary disease (COPD) have been performed, and data on adherence to national guidelines are scarce. The aims of the present study were to audit hospitalizations for COPD exacerbations in three Scandinavian hospitals with respect to incidence, patient population and standards of hospital care.Retrospectively all hospitalizations in the Departments of Internal and Respiratory Medicine in Östersund Hospital (Sweden), Aalesund Hospital (Norway) and Trondheim University Hospital (Norway) from Jan 1 to Dec 31, 2005, with discharge ICD-10 diagnoses J43–J44, J96 + J44 or J13-18 + j44 were registered. A total of 1144 admissions (731 patients) were identified from patient administrative systems and medical charts.Among the admitted patients 27% were >80 years old, >50% had COPD stage III or IV, and 14% had respiratory acidosis at admittance. Patients with 3 or more admissions (13%) during 2005 accounted for 36% of all hospitalizations. One third of the patients were current smokers. Non-invasive ventilation was used in 14% of the admissions, with large variation between centres. In-hospital mortality was 3.7%.In this first large Scandinavian audit of COPD-hospitalizations, all centres had low in-hospital mortality. We consider this as an indication of good clinical practice in the three studied centres and possibly due to the frequent use of non-invasive ventilation.
