简要总结
Chronic obstructive pulmonary disease (COPD) is a chronic lung disease primarily caused by smoking. COPD creates a tremendous burden to the healthcare system, as disease exacerbations result in frequent, prolonged hospitalizations. While originally considered a disease specific to the lung, data has shown that COPD is associated with substantial cardiovascular (CV) morbidity and mortality. Exacerbations of COPD requiring hospitalization result in marked patient deterioration, and heightened CV risk. The cause of the increased CV risk with stable COPD, and the exaggerated CV risk during exacerbations of the disease are unknown; however, it may be due to chronic inflammation which is exacerbated with a flare-up of the disease, and/or chronic inactivity which is similarly worsened with bed-rest during a hospitalization. Despite the impact of COPD on healthcare, there are relatively few studies examining how COPD inpatient care impacts on patient outcomes, inflammation and CV risk. Disease management programs, such as pulmonary rehabilitation and patient self-management education, are part of guideline therapy for COPD; however, these are not regularly implemented following a hospitalization, and how these interventions affect patient outcomes, behavior, physical activity, inflammation and CV risk have not been well studied. The proposed long-term project will examine how early referral to chronic disease management programs after hospital discharge, affect patient outcomes. This study will provide invaluable information about outpatient management for a disease which has a tremendous impact on healthcare.
详细描述
Purpose: To examine the impact of early pulmonary rehabilitation (PR) following hospital discharge on QoL, pulmonary/CV outcomes and AECOPD hospitalizations.
Rationale: In addition to typical improvements in QoL and exercise tolerance, studies have shown that PR increases self-efficacy and physical activity while reducing CV risk in stable COPD patients. Patients recently discharge from hospital following AECOPD represent the sickest patients with greatly reduced QoL, exercise tolerance, self-efficacy and physical activity. Exactly how these improve with PR following a hospitalization requires examination.
Hypothesis: Patients who receive early PR will have improved QoL, pulmonary/CV outcomes and less hospitalizations for COPD in the 6 months following hospital discharge. PR will improve self efficacy, physical activity and QoL while reducing CV risk as compared to usual care.
Study Design & Subject Recruitment: All patients admitted to the pulmonary ward for an AECOPD, will be offered participation into the study. Patients found to have an acute cardiac injury during admission, mobility issues or residence outside the greater Edmonton area will be excluded. Consenting patients will be subsequently randomized into one of three groups: early PR versus late PR versus usual care. Patients randomized to PR will be enrolled within 1 (Early PR; EPR) or 3 months (Late PR; LPR) of discharge into a PR program. Usual care patients will be followed-up by their most responsible physician as determined by the admitting team. The PR group will be enrolled in the Breathe Easy Program at the Center for Lung Health, and will proceed through the program in a typical fashion. All patients will be followed up 6 months after discharge and will be interviewed to assess disease status, management review and if there has been a history of recurrence or relapse of the AECOPD. Hospital admissions and length of stay data will be obtained through electronic medical records. Patient assessments will include: quality of life, 6min walk, dyspnea, self-efficacy, physical activity, pulse wave velocity, vascular function, systemic inflammation (TNFα, MMP-2, IL-6 and CRP) and FeNO. All data will be collected before, immediately after and 6 months after PR. The control group will have the same data collected at the same scheduled time. See above for descriptions of methods.
Data Handling: Data will be entered onto a secure anonymized database.
