Abstract

Background: Implementation of the COPD-Home integrated disease management (IDM) intervention at discharge after hospitalizations for acute exacerbations of COPD (AECOPD) led to reduced hospital utilization during the following 24 months compared to the year prior to study start.

Aims: To analyze the impact of the COPD-Home IDM intervention on health related quality of life, symptoms of anxiety and depression, and the degree of patient activation during 24 months of follow-up and to assess the association between these outcomes.

Methods: A single center, prospective, open, controlled clinical study. Changes in The St. George Respiratory Questionnaire (SGRQ), the Hospital anxiety (HADS-A) and depression (HADS-D) and the patient activation measure (PAM) scores were compared between the patients in the integrated care group (ICG) and the usual care group (UCG) 6, 12 and 24 months after enrolment.

Results: The questionnaire response rate was 80-96%. There were no statistically significant differences in the change of the SGRQ scores between the groups during follow up. After 12 months of follow-up there was a trend towards a reduction in the mean HADS-A score in the ICG compared to the UCG. The HADS-D scores remained stable in the ICG compared with an increasing trend in the UCG. Clinically significant difference in the PAM score was achieved only in the ICG, 6.7 (CI95% 0.7 to 7.5) compared to 3.6 (CI95% -1.4 to 8.6) in the UCG. In a logistic regression model a higher HADS-D score and current smoking significantly increased the odds for a low PAM score.

Conclusion: The COPD-Home IDM intervention did not result in any statistically significant changes in mean SGRQ, HADS-A, HADS- D or PAM scores during the 24 months of follow-up.

Trial registration: The ID number for the study in the Clinical.Trials.gov registration system is 17417. ClinicalTrials.gov Identifier: NCT 00702078.

Trial registration: ClinicalTrials.gov NCT00702078.
