Non-antimicrobial interventions in recovery from community acquired pneumonia in adults

Purpose of review: We review recent evidence on the effectiveness of non-antimicrobial adjunctive interventions on the recovery of adults diagnosed with community-acquired pneumonia (CAP). Recent findings: Respiratory physiotherapy, early mobilization or tailored exercises may decrease length of stay (LoS), dyspnoea and readmissions, but there is little evidence of an effect on mortality. Nutritional interventions may decrease readmissions and improve 30-day mortality, but there are few studies on the effect of individual micronutrient supplementation. Strategies to improve discharge communications and patient education may decrease readmission rates, improve treatment compliance and patient satisfaction, whereas the implementation of guidelines and care bundles may decrease 30-day mortality but does not appear to affect length of stay or 30-day readmissions. For adjunctive therapeutic interventions, there is evidence that for severe CAP, corticosteroids probably decrease short-term mortality and possibly longer-term mortality and LoS. Anti-platelet agents and statins may decrease short-term mortalitySummary: A wide range of adjunctive interventions have been trialed aiming to improve patient outcomes with variable results and considerable heterogeneity between studies and populations. Future studies should involve engagement with patient groups to identify uncertainties and outcomes they consider important, utilise a core set of outcome measures, and assess long-term outcomes.
