Characterisation of Patients With Chronic Obstructive Pulmonary Disease (COPD) From an Urban Municipality in the Northern Region of Portugal: A Cross-Sectional Study.

ABSTRACT

Background Pulmonary rehabilitation (PR) is formally indicated to all COPD patients in groups B and E. It positively impacts dyspnoea, health-related quality of life and exercise tolerance, reducing admissions among people with chronic obstructive pulmonary disease (COPD) who have had a recent exacerbation and symptoms of anxiety and depression. There is limited access to PR programmes in Portugal, partially due to insufficient resources or referrals. This study aims to characterise COPD patients and assess whether they have criteria for PR programmes. Data from this study may provide strategic information for healthcare organisations to differentiate and innovate their response to COPD patients. Methodology A cross-sectional study was conducted in an urban municipality in the northern region of Portugal. The sample was randomly extracted from the national primary electronic health records. The sample size (n = 339) was determined considering the population of COPD patients in this region (N = 2818), a 95% confidence level and a margin of error of 5%. Results In this population, the prevalence of COPD is 1.8%. Furthermore, in this sample, 40% (n = 136) of people diagnosed with COPD have a formal indication to participate in PR programmes, although only 14.2% (n = 48) of these patients had access to PR. Conclusion COPD is probably underdiagnosed in this Portuguese region. Most COPD patients have eligibility criteria to be offered PR programmes, although most of them do not benefit from this vital treatment. Investing in community and home-based programmes may increase PR access, reducing acute exacerbation of chronic obstructive pulmonary disease (AECOPD) admissions.
