Persistent fever after the first day of treatment differs significantly from fever persisting or recurring at day 7 of treatment.

IDSA CAP Guidelines

Influenza is often suspected on accquired basis of typical symptoms during the proper season in the presence of an epidemic. Microbiological studies may support the diagnosis of pneumonia due to an infectious agent, but routine tests are frequently falsely negative and are often nonspecific. Revisions of the criteria or alternative criteria were, therefore, recommended.

Table 11 provides a construct for evaluating nonresponse to antibiotic treatment of CAP, based on several studies addressing this issue [ 768184]. Doxycycline can be used as an alternative to a macrolide on the basis of scant data for treatment of Legionella infections [, ]. Such models do not account for substantial variability among patients, nor do they account for variable end points, such as limitation of care in patients with end-stage underlying diseases who present with CAP.

Although influenza remains the predominant viral cause of CAP in adults, other commonly recognized viruses include RSV [ ], adenovirus, and parainfluenza virus, as well as less common viruses, including human metapneumovirus, herpes simplex virus, varicella-zoster virus, SARS-associated coronavirus, and measles virus.

Controversial topics were assigned to 2 committee members, 1 from each society. The yield of cultures is substantially higher with endotracheal aspirates, bronchoscopic sampling, or transthoracic needle aspirates [ — ], although specimens obtained after initiation of antibiotic therapy are unreliable and must be interpreted carefully [, ].


Although there are favorable reports of the utility of Gram stain [ ], a meta-analysis showed a low yield, considering the number of patients with adequate specimens and definitive results [ ]. Third, specific interventions more easily performed in the ICU e. The intranasally administered live attenuated vaccine is an alternative vaccine formulation for some persons 5—49 years of age without chronic underlying diseases, including immunodeficiency, asthma, or chronic medical conditions.

Other aspects of the management of severe sepsis and septic shock in patients with CAP do not appear to be significantly different from those for patients with other sources of infection. Substantial overlap exists among the patients these guidelines address and those discussed in the recently published guidelines for health care-associated pneumonia HCAP [ 10 ].

Discharge should be considered when the patient is a candidate for oral therapy and when there is no need to treat any comorbid illness, no need for further diagnostic testing, and no unmet social needs [ 32, ]. Comorbidities or recent antimicrobial therapy increase the likelihood of infection with DRSP and enteric gram-negative bacteria.

With the exception of Legionella species, these microorganisms are common causes of pneumonia, especially among outpatients. The prevalence of anemia and its association with day mortality in hospitalized community-acquired pneumonia.

Other clmmunity members or coworkers may have developed viral symptoms in the interval since the patient was admitted, increasing suspicion of this cause. The decision for admission to an ICU vs. Whether the same results would be applicable to CAP cases is unclear, but the presence of cavities or other signs of tissue necrosis may warrant prolonged treatment. Mortality was higher when 3, 4, or 5 factors were present and was reported as The three strongest predictors for ICU admission were hypoxemia, confusion and leucopenia in the univariate analyses.


This document was then submitted to the societies for approval.

Improving the care of adult patients with community-acquired pneumonia CAP has been the focus scquired many different organizations, and several have developed guidelines for management of CAP. The yield of blood cultures is, therefore, relatively low although it is similar to yields in other serious infectionsand, when management decisions are analyzed, the impact of guidrlines blood cultures is minor []. The guidelines are intended primarily for use by emergency medicine physicians, hospitalists, and primary care practitioners; however, the extensive literature evaluation suggests that they are also an appropriate starting point for consultation by specialists.

The content is solely communjty responsibility of the authors and does not necessarily represent the official views of the National Heart, Lung, And Blood Institute or the National Institutes of Health. At present, the committee is awaiting further evaluation of the safety of this drug by the FDA before making its final recommendation.

However, until more accurate and rapid diagnostic methods are available, the axquired treatment for most patients will remain empirical. Patients with CAP appropriate for immunomodulatory treatment must be identified.

However, no antibiotic changes were based solely on sputum smears, suggesting that invasive cultures or nonculture methods may be needed. Although methicillin-resistant strains of S. Delay in beginning antibiotic treatment during the transition from the ED is not uncommon. Even in the presence of pneumococcal bacteremia, a switch to oral therapy can be safely done once clinical stability is achieved and prolonged intravenous therapy is not needed [ ].
