BACKGROUND: Community-acquired pneumonia (CAP) is common and often severe.
PURPOSE: To examine the effect of adjunctive corticosteroid therapy on mortality, morbidity, and duration of hospitalization in patients with CAP.
DATA SOURCES: MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials through 24 May 2015.
STUDY SELECTION: Randomized trials of systemic corticosteroids in hospitalized adults with CAP.
DATA EXTRACTION: Two reviewers independently extracted study data and assessed risk of bias. Quality of evidence was assessed with the Grading of Recommendations Assessment, Development, and Evaluation system by consensus among the authors.
DATA SYNTHESIS: The median age was typically in the 60s, and approximately 60% of patients were male. Adjunctive corticosteroids were associated with possible reductions in all-cause mortality (12 trials; 1974 patients; risk ratio [RR], 0.67 [95% CI, 0.45 to 1.01]; risk difference [RD], 2.8%; moderate certainty), need for mechanical ventilation (5 trials; 1060 patients; RR, 0.45 [CI, 0.26 to 0.79]; RD, 5.0%; moderate certainty), and the acute respiratory distress syndrome (4 trials; 945 patients; RR, 0.24 [CI, 0.10 to 0.56]; RD, 6.2%; moderate certainty). They also decreased time to clinical stability (5 trials; 1180 patients; mean difference, -1.22 days [CI, -2.08 to -0.35 days]; high certainty) and duration of hospitalization (6 trials; 1499 patients; mean difference, -1.00 day [CI, -1.79 to -0.21 days]; high certainty). Adjunctive corticosteroids increased frequency of hyperglycemia requiring treatment (6 trials; 1534 patients; RR, 1.49 [CI, 1.01 to 2.19]; RD, 3.5%; high certainty) but did not increase frequency of gastrointestinal hemorrhage.
LIMITATIONS: There were few events and trials for many outcomes. Trials often excluded patients at high risk for adverse events.
CONCLUSION: For hospitalized adults with CAP, systemic corticosteroid therapy may reduce mortality by approximately 3%, need for mechanical ventilation by approximately 5%, and hospital stay by approximately 1 day.
PRIMARY FUNDING SOURCE: None.
Time to clinical stability in patients hospitalized with community-acquired pneumonia: implications for practice guidelines.

CONTEXT: Many groups have developed guidelines to shorten hospital length of stay in pneumonia in order to decrease costs, but the length of time until a patient hospitalized with pneumonia becomes clinically stable has not been established.
OBJECTIVE: To describe the time to resolution of abnormalities in vital signs, ability to eat, and mental status in patients with community-acquired pneumonia and assess clinical outcomes after achieving stability.
DESIGN: Prospective, multicenter, observational cohort study.
SETTING: Three university and 1 community teaching hospital in Boston, Mass, Pittsburgh, Pa, and Halifax, Nova Scotia.
PATIENTS: Six hundred eighty-six adults hospitalized with community-acquired pneumonia.
MAIN OUTCOME MEASURES: Time to resolution of vital signs, ability to eat, mental status, hospital length of stay, and admission to an intensive care, coronary care, or telemetry unit.
RESULTS: The median time to stability was 2 days for heart rate (<or =100 beats/min) and systolic blood pressure (>or =90 mm Hg), and 3 days for respiratory rate (<or =24 breaths/min), oxygen saturation (>or =90%), and temperature (<or =37.2 degrees C [99 degrees F]). The median time to overall clinical stability was 3 days for the most lenient definition of stability and 7 days for the most conservative definition. Patients with more severe cases of pneumonia at presentation took longer to reach stability. Once stability was achieved, clinical deterioration requiring intensive care, coronary care, or telemetry monitoring occurred in 1% of cases or fewer. Between 65% to 86% of patients stayed in the hospital more than 1 day after reaching stability, and fewer than 29% to 46% were converted to oral antibiotics within 1 day of stability, depending on the definition of stability.
CONCLUSIONS: Our estimates of time to stability in pneumonia and explicit criteria for defining stability can provide an evidence-based estimate of optimal length of stay, and outline a clinically sensible approach to improving the efficiency of inpatient management.
