Providing palliative care to patients with chronic obstructive pulmonary disease (COPD) is a priority. Spirometry demonstrating airflow limitation is a diagnostic test for COPD and a common inclusion criterion for palliative care research. However, there are barriers to spirometry, and requiring spirometry with airflow limitation may exclude appropriate patients unable to complete spirometry, or patients with preserved-ratio impaired spirometry and symptoms or imaging consistent with COPD.
