[Adherence to pulmonary rehabilitation: An exploratory review]

Currently, several studies have identified low adherence to pulmonary rehabilitation in patients with COPD, despite the positive effects of the treatment. Patient adherence to pulmonary rehabilitation is affected by factors such as the absence of family support, and the presence of multiple comorbidities, respiratory distress, anxiety and depression. Given that there is no conclusive evidence about which of these factors are most influential in determining adherence to pulmonary rehabilitation in patients with COPD, we conducted this scoping review to analyse the available evidence on the factors influencing the adherence of patients with COPD to pulmonary rehabilitation programs (PRP). A wide literature search was carried out in Medline, Ovid, Science Direct, EMBASE, EBSCO and ISI-web of science, with prior definition of the selection criteria that included the factors associated with healthcare and adherence in patients with COPD in PRP. We used the adherence model proposed by the WHO as a conceptual framework. As a significant result, we found that factors in the dimension of illness (40%) and patient (30%) were the most frequently found dimensions in the studies, revealing that the design of pulmonary rehabilitation programs must take into account the specific needs of the patient. Further studies are needed to establish barriers and facilitators of adherence among COPD patients to PRP in the Colombian setting.
