Examine the Impact of Early Education on COPD Management

Chronic Obstructive Pulmonary Disease (COPD) Clinical Trial

Official title: Examine the Impact of Early Chronic Disease Management Education Following Hospital Discharge in Acute Exacerbation of COPD

Status Completed

Clinical Trial Summary

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.

Clinical Trial Description

Purpose: To examine the impact of early pulmonary education (PE) following hospital discharge on QoL, pulmonary/CV outcomes and AECOPD hospitalizations.

Rationale: Studies have shown that education improves self-efficacy and QoL in COPD. Whether these improvements translate to increased exercise tolerance, physical activity, reduced CV risk and hospitalizations in patients recently discharged from hospital requires examination.

Hypothesis: Patients who receive early education will have improved QoL, pulmonary/CV outcomes, and less COPD hospitalizations in the 6 months following hospital discharge. Education will improve self efficacy, physical activity and QoL while reducing CV risk as compared to usual care.

Study Design & Subject Recruitment: In Calgary, patients discharged following an AECOPD hospitalization are referred to the Calgary COPD and Asthma Program (CCAP) where they are seen by a Certified Respiratory Educator 1-2 times within the month following discharge. For this study, patients will be recruited from the CCAP program and randomized into receiving usual care; general education sessions over the month following discharge, or the experimental arm; focused education following discharge from hospital. Patients found to have an acute cardiac injury, mobility issues or residence outside the greater Calgary area will be excluded. All education visits will be 1hr in length, and occur at a local outpatient clinic. The education will focus on patient self-management and will use Living Well with COPD supporting literature (www.livingwellwithcopd.com) designed to improve patient self-management and physical activity. 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 will be obtained through electronic medical records as described above. Patient assessments will include: quality of life, 6min walk, dyspnea, self-efficacy, physical activity, pulse wave velocity (PWV), vascular function and systemic inflammation (TNF, MMP-2, IL-6 and CRP). All data will be collected before, immediately and 6 months after education. 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.

Data Analysis: The influence of education on QoL, 6min walk, dyspnea, self-efficacy, physical activity, pulse wave velocity, vascular function and systemic inflammation will be evaluated using a multivariate mixed-model multivariate analysis of variance (MANOVA) with treatment (education vs. usual care) being a fixed between-group variable and time (pre, immediate post, 6months post) as a repeated variable.

Sample size: Based on previous work, a total sample size of 140 (70 in each group) will be sufficient to detect a clinically significant difference in QoL and a significant difference in hospital readmission rates. Based on outhe investigators r recent work, this sample could detect a 10% difference in PWV and physical activity. ;
