Efficacy of an educational intervention in primary health care in inhalation techniques: study protocol for a pragmatic cluster randomised controlled trial.

Background: Chronic obstructive pulmonary disease (COPD) accounts for 10-12 % of primary care consultations, 7 % of hospital admissions and 35 % of chronic incapacity related to productivity. The misuse of inhalers is a significant problem in COPD because it is associated with reduced therapeutic drug effects leading to lack of control of both symptoms and disease. Despite all advice, health care professionals' practice management of inhalation treatments is usually deficient.

Study protocol for a randomized, controlled trial comparing the efficacy of two educational interventions to improve inhalation techniques in patients with chronic obstructive pulmonary disease (COPD): TIEPOC Study.

Background: An appropriate inhalation technique and adherence to treatment are both critical determinants of the success of chronic obstructive pulmonary disease (COPD) management. We have observed that up to 75% of patients do not use a successful inhalation technique. Knowledge evaluation and frequent reassessment of inhaler use, together with education of patients and healthcare professionals, can significantly improve the benefits that patients with COPD will derive from inhaler therapy.
