To evaluate the effectiveness and adverse eventsof nonpharmacologic interventions in patients with exacerbation of chronicobstructive pulmonary disease (COPD).
Patients and Methods:
We searched Embase, MEDLINE, Cochrane databases,Scopus, and clinicaltrials.gov from database inception to January 2, 2019, forrandomized controlled trials that enrolled adults with exacerbation of COPD andevaluated the effect of nonpharmacologic interventions on clinical outcomesand/or lung function.
We included 30 randomized controlled trials with2643 participants. Improvement in 6-minute walking test distance was associatedwith resistance training (weighted mean difference [WMD], 74.42; 95% CI, 46.85to 101.99), pulmonary rehabilitation (WMD, 20.02; 95% CI, 12.06 to 28.67),whole body vibration (WMD, 89.42; 95% CI, 45.18 to 133.66), and transcutaneouselectrical nerve stimulation (WMD, 64.54; 95% CI, 53.76 to 75.32). Improvementin quality of life was associated with resistance training (WMD, 18.7; 95% CI,5.06 to 32.34), combined breathing technique and range of motion exercises(WMD, 14.89; 95% CI, 5.30 to 24.50), whole body vibration (WMD, -12.02; 95% CI,-21.41 to -2.63), and intramuscular vitamin D (WMD, -4.67; 95% CI, -6.00 to-3.35 at the longest follow-up). Oxygen titration with a target oxygensaturation range of 88% to 92% was associated with reduced mortality comparedwith high flow oxygen (odds ratio, 0.36; 95% CI, 0.14 to 0.88). All findingswere based on low strength of evidence.
In patients hospitalized for exacerbation ofCOPD, exercise interventions and pulmonary rehabilitation programs mayameliorate functional decline. Oxygen should be titrated with a target oxygensaturation of 88% to 92% in these patients.
