Examine the Impact of Early Education on COPD Management

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.

Inclusion criteria

• All patients admitted to the pulmonary ward for an AECOPD will be offered participation into this arm of the study.

Exclusion criteria

• Patients found to have an acute cardiac injury during admission, mobility issues or residence outside the greater Calgary area will be excluded.
