Since the timeliness and appropriateness of antibiotics improves outcome in virtually all forms of pneumonia, clinicians should strive to ensure timely antibiotic treatment preferably within 6 hrs of symptom onset or presentation.

These antibiotics must also be active against the likely pathogen to optimize outcomes. Emergency management of the patient with pneumonia includes establishing an airway, if needed, and maintaining adequate oxygenation and ventilation, and for those patients in shock rapid fluid resuscitation is crucial.

In all patients, if there is any concern for a significant or growing pleural effusion it should be tapped to determine whether there is an accompanying empyema, since this must be drained urgently. Chest imaging represents the most important diagnostic test for establishing the presence of pneumonia. Other diagnostic tests focus on identifying the etiologic pathogen. This generally involves cultures of sputum, blood and pleural fluid if present. In patients who cannot produce sputum, inducing sputum with the help of respiratory therapy should be considered.

Blood cultures are recommended for patients with HCAP. In CAP, the evidence supporting routine blood cultures is more limited. Except for critically ill patients with CAP, blood cultures are more likely to grow a contaminant than a true pathogen. In mechanically ventilated patients, clinicians should consider obtaining lower airway cultures rather than simply tracheal aspirates.

Lower airway cultures are more reliable than tracheal aspirates and are less likely to be confounded by upper airway colonization. Examples of lower airway cultures include both bronchoscopic and non-bronchoscopic techniques. Bronchoscopic approaches include traditional broncheal alveolar lavage BAL and bronchial brush. Mini-BAL and blind-brush are options for non-bronchoscopic alternatives. Both bronchoscopic and non-bronchoscopic means for obtaining culture material are considered to be equivalent for diagnostic purposes in the non-immunocompromised host.

Other tools for identifying the pathogen include urinary antigen testing and serum antibody studies. Urinary antigen tests are commercially available for Streptococcus pneumoniae and selected Legionella species.

Measuring specific antibody titers and then re-evaluating the subject weeks later to determine the convalescent titer has no value outside of clinical research.

In immunosuppressed patients, special stains should be ordered to evaluate sputum and BAL specimens for the presence of Pneumocystis jiroveci PJP and selected fungi. In otherwise normal hosts, these tests are of little value. When clinically suspected based on the clinical and epidemiologic scenario, acid fast stains and subsequent cultures are appropriate to rule out mycobacterial disease.

Genetic probing of sputum and lower airway material can also prove helpful in the proper setting. In the end, the diagnosis of pneumonia is a clinical one. The physician must assemble and integrate the information and patient presentation along with results from objective testing to determine if the patient has pneumonia.

Again, each aspect of diagnostic testing undertaken in pneumonia has limited sensitivity. In other words, the differential diagnosis for an elevation in the WBC count is huge, as is the differential for an abnormal chest film.

Decision aids exist to help make the diagnosis more objective. For example, the clinical pulmonary infection score CPIS integrates various aspects of the clinical presentation and the objective testing into a score.

The higher the score, the more likely the patient is to have infectious pneumonia rather than some alternate process.

The CPIS, though, has very limited utility.
