Integrated disease mangement interventions for patients with chronic pulmonary disease (review)

__Abstract__ In people with chronic obstructive pulmonary disease (COPD) there is considerable variation in symptoms, limitations and wellbeing, which often complicates medical care. To improve quality of life (QoL) and exercise tolerance, while reducing the number of exacerbations, a multidisciplinary program including different elements of care is needed. To evaluate the effects of integrated disease management (IDM) programs or interventions in people with COPD on health-related QoL, exercise tolerance and number of exacerbations. We searched the Cochrane Airways Group Register of trials, CENTRAL, MEDLINE, EMBASE and CINAHL for potentially eligible studies (last searched 12 April 2012). Randomized controlled trials evaluating IDM programs for COPD compared with controls were included. Included interventions consisted of multidisciplinary (two or more health care providers) and multi-treatment (two or more components) IDMprograms with a duration of at least three months. Two review authors independently assessed trial quality and extracted data; if required, we contacted authors for additional data. We performed meta-analyses using random-effects modeling. We carried out sensitivity analysis for allocation concealment, blinding of outcome assessment, study design and intention-to-treat analysis.
