This pre/post study was a retrospective analysis of unplanned hospitalization rates in a cohort of COPD subjects started on remote physiologic monitoring (RPM) at a large, outpatient pulmonary practice. The study included all subjects with high healthcare utilization (≥1 hospitalization or emergency room visit in the prior year) who had elected to enroll in an RPM service for assistance with clinical management. Additional inclusion criteria included being on RPM for at least 12 months and a patient of the practice for at least two years (12 months pre- and post-initiation of RPM).

This study included a retrospective analysis of data collected from subjects at a large outpatient pulmonology practice in the mid-Atlantic region of the United States between May 2019 and February 2022. At this clinic, patients who were candidates for RPM had been offered voluntary participation in service tailored to chronic respiratory disease patients (Spire Health, San Francisco, CA, USA). They continued regular follow-ups with their pulmonologists and received usual care according to the direction of their primary pulmonary physician for their COPD.

Inclusion criteria for the present study included a clinical diagnosis of COPD (COPD, chronic bronchitis, obstructive lung/airways disease, or emphysema), subscribed to RPM for at least 12 months as of February 28, 2022, full electronic medical records (EMR) at the site in question for one year before and one year after the start of RPM, and high healthcare utilization (≥1 ER visit or hospitalization in the year prior to enrollment). All such patients were included in the analysis.

The primary endpoint was unplanned, all-cause hospitalizations per subject. Secondary endpoints included unplanned cardiopulmonary hospitalizations, respective lengths of stay, ER visits, outpatient pulmonary visits, and systemic corticosteroid use, adherence to RPM, and time-to-visit (RPM escalation to provider visit).

Inclusion Criteria:

• Clinical diagnosis of COPD (COPD, chronic bronchitis, obstructive lung/airways disease, or emphysema)
• ≥1 hospitalization or emergency visit in the year prior to enrollment
• enrolled in the Spire RPM patient monitoring service for at least 12 months
• a patient of the practice for at least two years (12 months pre- and 12 months post-initiation of RPM).

Exclusion Criteria:

• None

COPD patients at a large outpatient pulmonology practice in the mid-Atlantic region of the United States. They were all candidates for RPM and were offered a voluntary participation in a service tailored to chronic respiratory disease patients.
