- Brief Summary
The purpose of this trial is to determine whether a minimal homebased psychoeducative intervention is effective in management of anxiety and dyspnea in patients with severe chronic obstructive pulmonary disease.
- Detailed Description
In patients with severe chronic obstructive pulmonary disease (COPD) anxiety and dyspnea are described as the primary symptoms with a high impact on the patients quality of life and use of social services. Both pharmacological and non-pharmacological strategies aimed at reducing anxiety in patients with severe illness are challenged by low compliance and/or side-effect, which emphasized the need of focusing on treatment strategies that addresses the issues characteristic for a population with severe pulmonary disease.
The trial is a single-centre randomised clinical trial that test the hypothesis that a minimal homebased psychoeducative intervention reduces anxiety in patients with severe COPD. The primary outcome is anxiety assessed by the hospital and anxiety and depression scale (HADS), subscale for anxiety (HADS-A). Secondary outcomes are mastery of dyspnea measured by the Chronic Respiratory Questionnaire (CRQ), Health-related Quality of Life (HRQL) measured by the St. George Respiratory Questionnaire (SGRQ) and depression measured by the HADS, subscale for depression (HADS-D). The outcomes will be assessed at follow-up four weeks and three months after the intervention.
The trial population consist of patients with severe COPD affiliated the Department of Pulmonary \& Infectious Diseases at Nordsjællands Hospital. Based on a sample size calculation sixty-six patients with severe COPD and associated anxiety will be randomised 1:1 to either intervention plus usual care or to usual care.
The intervention consist of a minimal psychoeducative dialogue delivered in the patient's home follow by a telephone booster session after two weeks. The intervention is based on a manual, where the theoretical foundation is cognitive behavior theory. The intervention is carried out by a nurse.
Our primary outcome of interest is intra-individual differences in HADS-A scores between baseline and last follow-up after three months. To analyse this with-in group difference in outcome we use paired t-test or Wilcoxon signed-rank. Differences between the groups will similarly be assessed with two-sample t-test or Wilcoxon rank-sum test. Same strategy will be used analyzing the secondary outcomes CRQ, SGRQ and HADS-D.
To include all points of follow-up and to evaluate the development with-in group and between groups we use a longitudinal regression model. Because of an expected high number of drop outs, the censuring due to death and missing data due to possibly lost to follow up will be handled appropriately, under supervision and in collaboration with an experienced bio-statistician. The sample size calculation is based on HADS-A, a paired design and a estimated drop-out of 33.3 %.
The trial is designed with the aim of giving nurses and other health professionals an instrument clinically applicable in proving care for patients with severe COPD and associated anxiety. Positive or negative results of the trial will be submitted to international journals.
