Educational and supportive interventions for improving adherence to inhalation therapy in people with chronic respiratory diseases: A systematic review protocol

Abstract

Review question/objective The objective of this systematic review is to identify the best available research evidence related to the effectiveness of educational and supportive interventions for improving adherence to inhalation therapy in people with chronic respiratory diseases, focusing on measures of adherence and health outcomes. The specific review questions to be addressed are: 1. What is the effectiveness of educational and supportive interventions for improving adherence to inhalation therapy in terms of inhalation regimens and inhalation techniques in people with chronic respiratory diseases? 2. What is the effectiveness of educational and supportive interventions for improving adherence to inhalation therapy on health service utilization and patient outcomes including symptoms, pulmonary function, and quality of life? 3. What is the effectiveness of various designs, in terms of components, modes and intensities, of educational and supportive interventions for improving adherence to inhalation therapy? Inclusion criteria Types of participants This review will consider studies that include adults aged 18 or above, with a clinical diagnosis of chronic respiratory disease and prescribed self-administered inhalation therapy as a long term regular treatment, irrespective of the type of inhaler used. For the purposes of this review, "chronic respiratory diseases" is defined by WHO in 2007 as "the chronic diseases of the airways and other structures of the lung" (p.5). 1 Inhalation therapy is defined as "a treatment in which a substance is administered to the respiratory tract with inspired air". 6 This review will focus on inhalation of drugs. Those studies with prescribed administration of oxygen and water will be excluded. There is no universal standard for how long a treatment is undertaken to be defined as a "long term treatment". Acute episodic drug treatments, such as a course of antibiotics, will be excluded. Types of interventions of interest All educational interventions, with or without supportive programs, designed to improve the chronic respiratory disease sufferers inhalation technique and adherence to their prescribed inhalation therapy will be considered. Those studies that involve comparison of different types of inhalation medications, inhaler devices or inhalation methods to improve the adherence to inhalation therapy will be excluded.
