Abstract

Rationale: Physical inactivity is associated with increased hospitalizations among patients with COPD. The purpose of this investigation was to examine the effects of a behavioral physical activity intervention (BI) on hospitalizations.Methods: Patients were randomized to usual care (UC) or a BI delivered over 5-months. Self-reported hospitalizations for lung (HLD) and non-lung disease (HNLD) were measured at baseline, 6-, 12-, and 18-months. Poisson regression was used to estimate adjusted incidence rate ratios (IRR) of utilization over time.Results: 305 patients were randomized. In longitudinal analysis of individual change in hospitalization from baseline to 18 months there was no change in HNLD (data not shown). However, over 18 months HLD significantly declined (p<0.02) among the BI group and remained unchanged in the UC group (Table). Adjusted IRR suggested a trend of lower numbers (IRR=0.74 [0.53-1.04]) and duration (IRR=0.64 [0.38-1.08]) of HLD among the BI group over time.

Days HLD, mean (SD)	0.77 (2.49)	0.67 (2.09)	0.66 (2.66)	0.96 (3.26)
BI
HLD, n (%)	20 (13.4)	9 (7.3)	9 (7.5)	8 (7.1)
#HLD, mean (SD)	0.20 (0.64)	0.15 (0.79)	0.15 (0.79)	0.09 (0.34)
Days HLD, mean (SD)	1.12 (4.27)	0.54 (2.53)	0.72 (5.17)	0.25 (0.95)

 

Conclusion: This BI was associated with significantly fewer hospitalizations reported for COPD, and they were shorter in duration suggesting that health coaching to promote physical activity may decrease the frequency and severity of COPD exacerbations requiring hospitalization.
