Similar high health care and social care costs were found for pneumonia patients with COPD – the largest group having pneumonia episodes. The municipalities are responsible for 49% of the costs, while a closer focus on the prevention of pneumonia may be advisable, eg, starting with citizens having COPD.

Community-acquired pneumonia (CAP) is the most common type of pneumonia caused by bacteria, virus, or fungi and is ranked as the fifth leading cause of mortality globally.1 The most common cause of bacterial pneumonia in adults is Streptococcus pneumoniae (pneumococcus) accounting for up to 30% of all pneumonia cases.1 Increasing with age and comorbidi- Correspondence: Peter Bo Poulsen ties, the overall incidence of CAP among adults is increasing, now ranging between Pfizer Denmark ApS, Lautrupvang 8, DK-2750 Ballerup, Denmark 1.54 and 1.7 per 1,000 population in Europe.2 Tel +45 2920 3211 Pneumonia is often diagnosed among patients hospitalized with acute exacerbations Fax +45 4420 1114 Email [email protected] of COPD.
