Insufficient Pulmonary Rehabilitation Uptake After Severe Exacerbation of COPD: A Multicentre Study in the South West Region of France.

Purpose: Pulmonary rehabilitation (PR) is a type of multidisciplinary care strongly recommended after severe exacerbation of chronic obstructive pulmonary disease (COPD). Recently, a national French study reported a very low rate of PR uptake (8.6%); however, important clinical data were missing. Here, we aimed to identify the main factors associated with insufficient PR uptake after hospitalisation for COPD exacerbation. Patients and Methods: This multicentre retrospective study included patients hospitalised with COPD exacerbation between 1 January 2017 and 31 December 2018, as identified by both coding and a detailed review of medical records. PR was defined as inpatient care in a specialised centre or unit within 90 days of discharge. Multivariate logistic regression was used to identify associations between PR uptake and patient characteristics, such as comorbidities, non-invasive ventilation (NIV), inhaled treatment, and forced expiratory volume in 1 second (FEV1). Results: Among the 325 patients admitted for severe COPD exacerbation, 92 (28.3%) underwent PR within 90 days of discharge. In univariate analysis, relative to those who underwent PR, patients without PR had significantly more comorbidities, were less often treated with triple bronchodilator therapy or NIV, and had a higher FEV1. In multivariate analysis, variables independently associated with the lack of PR uptake were the presence of comorbidities (adjusted odds ratio (aOR) = 1.28 [1.10-1.53], p = 0.003) and a higher FEV1 (aOR = 1.04 [1.02-1.06], p < 0.001). There was no significant correlation between PR uptake and departmental PR centre capacity (notably, some departments had no PR facilities). Conclusion: These data highlight the lack of PR in the early stages of COPD. Collaboration among all healthcare providers involved in patient management is crucial for improved PR uptake.
