<qa>  What was the result of a Cochrane review?A number of interventions for improving clinical outcomes in CAP are now supported by recently accrued level 1 evidence. Following a Cochrane review in 2011 that suggested adjunct corticosteroids accelerate time to clinical stability, a number of trials have since demonstrated favorable outcomes. Most notable are two landmark large randomized controlled trials RCT; a study of the effect of corticosteroid on reducing treatment failure in severe CAP published in JAMA, and a study published in the Lancet in 2015 that demonstrated faster clinical recovery and shorter LOS by 1 day without significant adverse events.10 A subsequent meta-analysis 2000 patients from 12 RCTs confirmed these findings and routine adjunctive corticosteroid is now widely supported though as yet not consistently deployed. Early mobilization safely and effectively reduces LOS when applied appropriately as does early switch to oral antibiotics guided by a set of well-defined basic clinical and laboratory criteria. Recently, a RCT incorporating both measures demonstrated a LOS reduction of 2 days compared to standard care. A meta-analysis of nutritional support in malnourished medical inpatients a patient cohort that includes those admitted with CAP showed that systematic screening for risk of malnutrition and targeted nutritional therapy intervention reduces non-elective readmission rates.
