Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]

Overview

Infectious Diseases Society of America/American Thoracic Society consensus recommendation on empiric antibiotic treatment of community-acquired pneumonia in adults. ^[1] (DO NOT EDIT)

“

Previously healthy and no risk factors for drug-resistant Streptococcus pneumoniae

A macrolide (azithromycin, clarithromycin, or erythromycin (Strong recommendation; level I evidence)

Doxycycline (Weak recommendation; level III evidence)

Presence of comorbidities or other risks for drug-resistant Streptococcus pneumoniae

Presence of comorbidities, such as chronic heart, lung, liver, or renal disease; diabetes mellitus; alcoholism; malignancies; asplenia; immunosuppressing conditions or use of immunosuppressing drugs; use of antimicrobials within the previous 3 months (in which case an alternative from a different class should be selected); or other risks for DRSP infection:

A respiratory fluoroquinolone (moxifloxacin, gemifloxacin, or levofloxacin [750 mg]) (Strong recommendation; level I evidence)
A beta-lactam plus a macrolide (Strong recommendation; level I evidence) (High-dose amoxicillin [e.g., 1 g 3 times daily] or amoxicillin-clavulanate [2 g 2 times daily] is preferred; alternatives include ceftriaxone, cefpodoxime, and cefuroxime [500 mg 2 times daily]; doxycycline (level II evidence) is an alternative to the macrolide.)

In regions with a high rate (>25%) of infection

In regions with a high rate (>25%) of infection with high-level (minimal inhibitory concentration [MIC], >16 micrograms/mL) macrolide-resistant S. pneumoniae, consider the use of alternative agents for any patient, including those without comorbidities. (Moderate recommendation; level III evidence)

Inpatient, Non-ICU Treatment

The following regimens are recommended for hospital ward treatment.

A respiratory fluoroquinolone (Strong recommendation; level I evidence)

A beta-lactam plus a macrolide (Strong recommendation; level I evidence) (Preferred beta-lactam agents include cefotaxime, ceftriaxone, and ampicillin; ertapenem for selected patients; with doxycycline (level III evidence) as an alternative to the macrolide. A respiratory fluoroquinolone should be used for penicillin-allergic patients.)

Inpatient, ICU Treatment

The following regimen is the minimal recommended treatment for patients admitted to the ICU.

A beta-lactam (cefotaxime, ceftriaxone, or ampicillin-sulbactam) plus either azithromycin (level II evidence) or a fluoroquinolone (Strong recommendation; level I evidence) (For penicillin-allergic patients, a respiratory fluoroquinolone and aztreonam are recommended.)

For Pseudomonas infection, use an antipneumococcal, antipseudomonal beta-lactam (piperacillin-tazobactam, cefepime, imipenem, or meropenem) plus either ciprofloxacin or levofloxacin (750-mg dose)

or the above beta-lactam plus an aminoglycoside and azithromycin or the above beta-lactam plus an aminoglycoside and an antipneumococcal fluoroquinolone (for penicillin-allergic patients, substitute aztreonam for the above beta-lactam). (Moderate recommendation; level III evidence)

For community-acquired methicillin resistant Staphylococcus aureus (CA-MRSA) infection, add vancomycin or linezolid. (Moderate recommendation; level III evidence)

Infectious Diseases Society of America/American Thoracic Society consensus recommendation on pandemic Influenza community-acquired pneumonia in adults. ^[1] (DO NOT EDIT)

“

Pathogen-directed Therapy

Once the etiology of CAP has been identified on the basis of reliable microbiological methods, antimicrobial therapy should be directed at that pathogen (Moderate recommendation; level III evidence)
Early treatment (within 48 h of the onset of symptoms) with oseltamivir or zanamivir is recommended for influenza A. (Strong recommendation; level I evidence)
Use of oseltamivir and zanamivir is not recommended for patients with uncomplicated influenza with symptoms for >48 h (level I evidence), but these drugs may be used to reduce viral shedding in hospitalized patients or for influenza pneumonia. (Moderate recommendation; level III evidence)

Pandemic Influenza

Patients with an illness compatible with influenza and with known exposure to poultry in areas with previous H5N1 infection should be tested for H5N1 infection. (Moderate recommendation; level III evidence)
In patients with suspected H5N1 infection, droplet precautions and careful routine infection control measures should be used until an H5N1 infection is ruled out. (Moderate recommendation; level III evidence)
Patients with suspected H5N1 infection should be treated with oseltamivir (level II evidence) and antibacterial agents targeting S. pneumoniae and S. aureus, the most common causes of secondary bacterial pneumonia in patients with influenza. (Moderate recommendation; level III evidence)

Infectious Diseases Society of America/American Thoracic Society consensus recommendation on time, route, and duration of community-acquired pneumonia in adults. ^[1] (DO NOT EDIT)

“

Time to First Antibiotic Dose

For patients admitted through the emergency department (ED), the first antibiotic dose should be administered while still in the ED. (Moderate recommendation; level III evidence)

Switch from Intravenous to Oral Therapy

Patients should be switched from intravenous to oral therapy when they are hemodynamically stable and improving clinically, are able to ingest medications, and have a normally functioning gastrointestinal tract. (Strong recommendation; level II evidence).
Patients should be discharged as soon as they are clinically stable, have no other active medical problems, and have a safe environment for continued care. Inpatient observation while receiving oral therapy is not necessary. (Moderate recommendation; level II evidence)

Duration of Antibiotic Therapy

Patients with CAP should be treated for a minimum of 5 days (level I evidence), should be afebrile for 48 to 72 h, and should have no more than 1 CAP-associated sign of clinical instability before discontinuation of therapy. (level II evidence) (Moderate recommendation)
A longer duration of therapy may be needed if initial therapy was not active against the identified pathogen or if it was complicated by extrapulmonary infection, such as meningitis or endocarditis. (Weak recommendation; level III evidence)

Other treatments consideration

Infectious Diseases Society of America/American Thoracic Society consensus recommendation on other treatments considerations for acquired pneumonia in adults. ^[1] (DO NOT EDIT)

“

This recommendation has been removed due to the market withdrawal of drotrecogin alfa.
Hypotensive, fluid-resuscitated patients with severe CAP should be screened for occult adrenal insufficiency. (Moderate recommendation; level II evidence)
Patients with hypoxemia or respiratory distress should receive a cautious trial of noninvasive ventilation (NIV) unless they require immediate intubation because of severe hypoxemia (arterial oxygen pressure/fraction of inspired oxygen [PaO2/FiO2] ratio <150) and bilateral alveolar infiltrates. (Moderate recommendation; level I evidence)
Low-tidal-volume ventilation (6 cm3/kg of ideal body weight) should be used for patients undergoing ventilation who have diffuse bilateral pneumonia or acute respiratory distress syndrome. (Strong recommendation; level I evidence)

Management of Non-responding Pneumonia

Infectious Diseases Society of America/American Thoracic Society consensus recommendation on non responding acquired pneumonia in adults. ^[1] (DO NOT EDIT)

“

Because of the limitations of diagnostic testing, the majority of CAP is still treated empirically. Critical to empirical therapy is an understanding of the management of patients who do not follow the normal response pattern.
