Background: Guidelines for chronic obstructive pulmonary disease (COPD) recommend supplementing pharmacotherapy with non-pharmacological interventions. Little is known about the use of such interventions by patients. We analyzed the utilization of a number of non-pharmacological interventions and identified potential determinants of use.
Methods: Based on self-reports, use of interventions (smoking cessation, influenza vaccination, physiotherapy, sports program, patient education, pulmonary rehabilitation) and recommendation to use were assessed in 1410 patients with COPD. The utilization was analyzed according to sex and severity of disease. Potential determinants of utilization included demographic variables and disease characteristics and were analyzed using logistic regression models.
Results: Influenza vaccination in the previous autumn/winter was reported by 73% of patients. About 19% were currently participating in a reimbursed sports program, 10% received physiotherapy, 38% were ever enrolled in an educational program, and 34% had ever participated in an outpatient or inpatient pulmonary rehabilitation program. Out of 553 current or former smokers, 24% had participated in a smoking cessation program. While reports of having received a recommendation to use mainly did not differ according to sex, women showed significantly (p < 0.05) higher utilization rates than men for all interventions except influenza vaccination. Smoking was a predictor for not having received a recommendation for utilization and also significantly associated with a reduced odds of utilization. We found a correlation between recommendation to use and utilization.
Conclusions: Utilization of non-pharmacological interventions was lower in men and smokers. A recommendation or offer to use by the physician could help to increase uptake.
