Abstract

RATIONALE: Unintentional weight loss (UWL) is prevalent among patients with chronic obstructive pulmonary disease (COPD). However, little research has been done on UWL as an independent variable in terms of clinical outcome. The aim of this study was to investigate the association between BMI, UWL, and clinical outcome in terms of hospitalization, length of stay, exacerbations, mortality, and quality of life (QoL) within six months and one year in a hospital outpatient setting.

METHODS: A prospective single-center cohort study enrolled 200 patients from the COPD outpatient clinic between October 2020 and May 2021 at a Danish Hospital. At baseline, data was collected using patients' electronic journals and a quantitative questionnaire was gathered with a patient-reported UWL of 5% of body weight within three months. At six months and one-year follow-ups, data was collected using the patients' medical journals and a telephonic interview with the EQ-5D-5L and SARC-F questionnaire and the number of non-hospitalization exacerbations since inclusion. Data were analyzed using logistic and Cox hazard regression analysis.

RESULTS: A total of 187 patients were eligible for follow-up (mean age 69.2 years, 43.9% males, median BMI 26.8 kg/m2), and the prevalence of UWL was 13.4%. UWL was associated with an almost trifold risk of >five days stay (OR = 2.94, p = 0.021). Additionally, UWL was associated with a worse QoL. A higher risk of exacerbation was found in the underweight patients (OR = 4.94, p = 0.014). No significant difference in mortality was found.

CONCLUSION: UWL as a solitary factor is associated with increased hospital length of stay and a worse QoL. The results provide further evidence that implementation of regular screening for UWL in addition to BMI might be beneficial to include in international COPD guidelines for outpatient settings.
