Hospital-associated functional status decline in pulmonary patients
type: CreativeWork
description: 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. Thes…
