Indiana University-Purdue University Indianapolis (IUPUI) / Chronic obstructive pulmonary disease (COPD) is a significant worldwide cause
of chronic illness and mortality and one of the most common admitting diagnoses in the
United States. Persons with COPD are at increased risk for deconditioning during
hospitalization, which can lead to decreased functional status at discharge.
Disease-related factors and elements of the hospital environment make older adults with
COPD vulnerable to hospital-associated functional status decline. The purpose of this
dissertation was to identify activity factors that contribute to hospital-associated
functional status decline in older adults with COPD by promoting functioning during
hospitalization.
This predictive correlational study is a secondary analysis of a pre-existing
dataset. Patients with COPD were pulled from the larger parent study sample for
comparison with patients without COPD. The convenience sample consisted of 111
patients with COPD and 190 patients without COPD. Subjects were 46.5% male, 53.5%
female, and a mean age of 66 years. All subjects were patients admitted to a pulmonary
unit and received an intervention protocol designed to address mobility barriers related to
COPD and hospitalization.
Statistical analysis explored the number, type, and timing of activity events in
relation to the selected functional status outcomes of discharge disposition, length of
hospital stay, and 30-day readmission rates for hospitalized older adults with COPD.
Multivariate and bivariate analyses results indicated ambulation to the bathroom, ambulation outside the patient room, and number of days to first out-of-bed activity were
significant predictors (p < 0.05) of patient discharge to home; days to first activity and
ambulation were significant predictors (p < 0.05) of reduced length of stay; none of the
variables were predictive of 30-day readmission. Patients with COPD experienced longer
lengths of stay and more non-weight bearing activity than patients without COPD in this
sample.
These findings provide a foundation for future research to explore hospital
environmental factors influencing mobility, determine optimal modes of activity during
hospitalization, and examine potential cost savings associated with promotion of early
mobility. Findings help explain the effects of physical activity during hospitalization and
may aid development of nursing interventions to prevent or alleviate functional status
decline in this vulnerable population. / 2 years
