A national survey found that limited access to high-flow home oxygen is delaying hospital discharges and increasing risks and costs for patients and the healthcare system.

WASHINGTON, July 7, 2026 /PRNewswire-91ÉçÇø/ -- Across the country, people ready to be discharged from the hospital are being forced to stay extra nights due to a lack of adequate at-home oxygen supplies, a new survey found.

Discharge delays are costly for both the hospital and the patient.

"Remaining in the hospital setting poses significant added risks to patients ranging from financial costs to hospital-acquired infections," said Nick Kolaitis, MD. "These patients are medically ready to go home. The barrier is access to the right equipment, and this data makes clear it is not an isolated problem — it is happening at medical centers across the country."

The survey of 54 respiratory clinicians representing 40 medical centers across all U.S. regions found that 94% reported at least one discharge delay per month due to oxygen access issues, while a third of the respondents reported six or more of their patients experienced delays every month due to oxygen access issues. The majority of delays added two or more days to the patient's hospital stay.

Clinicians cited insurance approval delays (69%) and suppliers' inability to provide high-flow oxygen systems, such as liquid oxygen (67%) as primary barriers to discharge.

Patients with serious lung and heart conditions, including pulmonary hypertension, pulmonary fibrosis, chronic obstructive pulmonary disease, and those awaiting lung transplants, often require high-flow supplemental oxygen. Widely available portable oxygen concentrators cannot meet this need. Liquid oxygen systems, which provide high-flow oxygen in a lightweight, portable format that allows patients to leave their home and maintain independence are the preferred solution. However, most oxygen suppliers no longer carry or provide liquid oxygen equipment due to inadequate reimbursement from Medicare and other insurance plans.

As a result, hospitalized patients who are medically ready to go home, but require high-flow oxygen, cannot be discharged.

"This is the first time we have been able to document the impact of inadequate oxygen delivery options on hospital discharge at a national scale, and the results confirm what clinicians have been telling us for years. A lack of high-flow oxygen equipment leads to unnecessary hospital stays, increasing the burden on patients and the healthcare system," said Susan Jacobs, RN.

Survey results were presented as part of a presentation, "Delays in Hospital Discharge Due to Lack of Adequate Home Oxygen Systems," at the recent Pulmonary Hypertension Association's 2026 International PH Conference and Scientific Sessions in Dallas.

"Further analysis will help us understand the financial impact of paying for extra hospital days because Medicare doesn't cover high-flow home oxygen. Additional study is also needed on the indirect costs of extended hospital stays, including hospital acquired infection and quality of life issues," said Colleen Connor, study co-author living with pulmonary hypertension.

The survey was supported by PHA with input from a supplemental oxygen user, clinicians and a methodologist. It was distributed by the American Lung Association, Pulmonary Hypertension Association, Pulmonary Fibrosis Foundation, COPD Foundation and Foundation for Scleroderma Research. Clinician responses were collected from October 14 through November 18, 2025.
