Dobson | DaVanzo Publishes a Study in Respiratory Medicine

Published Thursday, July 14, 2022

Dobson | DaVanzo staff are pleased to announce a recently accepted study in Respiratory Medicine, titled, "Early Initiation of non-invasive ventilation at home improves survival and reduces healthcare costs in COPD patients with chronic hypercapnic respiratory failure: A retrospective cohort study".

Some highlights include:

  • Multi-year retrospective cohort study of patients with COPD-CRF receiving Non-invasive Ventilation at Home (NIVH) using 100% Medicare claims
  • Econometric IPTW matching methodology – Cox proportional hazard models for time-to-event outcomes and generalized least square model for Medicare expenditure outcomes.
  • Findings are that hypercapnic patients benefited in reduced mortality risk from NIVH applied within the first week after index; hypoxic patients did not reduce their risk of mortality.
  • Medicare expenditures for hypercapnic patients were lower in the 12 months after treatment than expenditures for either hypoxic or unspecified phenotypes.
