Community-acquired pneumonia (CAP) is the most important infectious disease in Germany. After 3 years of data recording, the country-wide competence network CAPNETZ presents reliable data on etiology and course of the disease, based on more than 3,500 prospectively observed patients. In the acute phase, lethality is as high as nearly 10%, and in the 6-month follow-up period after the acute infection, lethality is > 15%. A reliable detection of the underlying pathogen is possible in less than half of all patients studied. The most frequent pathogens are Streptococcus pneumoniae (40%), Haemophilus influenzae, and Mycoplasma pneumoniae (8% each). Legionella (3%) and Chlamydia pneumoniae (< 1%) are rarely found, and gram-negative enterobacteriaceae (< 5%) are restricted to high-risk patient groups (nursing home, multimorbidity). CAPs due to pneumococci, legionella or enterobacteriaceae were associated with increased lethality. Problems with resistances had not been found in Germany, except for a decreasing susceptibility of S. pneumoniae to macrolides. Viruses could be detected in nearly 15% of all pneumonia patients. The CRB-65 score allows a reliable discrimination between patients with a high and low risk of dying. The new S3 guideline for diagnosis and treatment of CAP recommends a risk-adapted treatment. Low-risk patients shall receive a monotherapy with, e. g., amoxicillin, high-risk patients should be treated with a broad-spectrum combination therapy (beta-lactam and macrolide).

According to the recommendations of the Swedish Community-Acquired Pneumonia (CAP) guidelines, the selection of empirical antibiotic therapy should be based on the CRB-65 rule. The guidelines recommend empirical therapy directed predominantly against Streptococcus pneumoniae for patients with low CRB-65 scores and broad-spectrum therapy for patients with high CRB-65 scores. In order to study the utility of the recommendations, we analyzed the data from an aetiological study previously performed on 235 hospitalized adult CAP patients at our medical centre. A definite, probable, or possible bacterial aetiology was noted in 194 cases (83%), including 112 cases (48%) with S. pneumoniae aetiology. The following frequencies of definite-probable aetiologies were noted in the patients with CRB-65 score 0-1 (n=155) and CRB-65 score 2-4 (n=80): S. pneumoniae 30% and 35%, Haemophilus influenzae 6.5% and 14% (p=0.063), Mycoplasma pneumoniae 15% and 5.0% (p=0.019), Chlamydophila species 2.6% and 1.2%, Legionella pneumophila 1.9% and 0%, and Staphylococcus aureus 1.3% and 1.2%, respectively. The high frequency of S. pneumoniae in the study supports the recommendations to predominantly cover this bacterium in the empirical therapy of patients with low CRB-65 scores. In the case of treatment failure in these patients, the study indicates that coverage against M. pneumoniae and H. influenzae should be considered.

Community-acquired pneumonia (CAP) is the most common form of severe infectious disease in developed countries. The mortality is particularly high in elderly patients. For risk stratification simple clinical scores such as the CRB-65 (confusion, respiratory rate, blood pressure, age over 65 years) are recommended. The spectrum of pathogens is characterized by Pneumococcus and Haemophilus influenzae as well as atypical and viral pathogens. Resistance plays a subordinate role in Germany. In addition to the clinical symptoms an X-ray examination is also helpful to confirm the diagnosis and biomarkers can also be useful. Microbiological investigations are not necessary in practice. Particularly in cases of uncharacteristic clinical symptoms and therapy failure there are many differential diagnoses which can be hidden behind the clinical diagnosis of pneumonia. The calculated treatment of CAP should correspond to the current recommendations in national guidelines. The options for prevention by general measures and vaccinations should be applied consistently.
