The Prescription Is Only the Beginning: Closing the Gap in Home Oxygen Care
A perspective for pulmonologists and referring specialists.
The part of the oxygen prescription the doctor cannot see
A pulmonologist sees a patient with advanced chronic respiratory disease. The indication is established, the assessment is done, oxygen is prescribed. The patient leaves with a script. Clinically, that can feel like the end of a decision.
Operationally, it is the beginning of an entirely different process. Someone now has to translate that prescription into equipment the patient can actually use at home. Someone has to explain what the oxygen is for, how the device works, what to do when leaving the house, whom to call when something fails, and how the medical-aid authorisation will be handled.
That space between the prescription and everyday use is where home oxygen therapy quietly succeeds or fails — and it is almost entirely invisible from the consulting room. This is not a theoretical concern. The 2017 American Thoracic Society workshop on optimising home oxygen therapy was convened precisely because functional problems, equipment failures, access barriers and inadequate patient education recur across the home oxygen pathway.
A correct prescription does not guarantee correct therapy
Oxygen is a prescribed therapy delivered through a device, and the device has to fit the clinical requirement. Patients differ: oxygen at rest, oxygen on exertion, continuous versus pulse-dose delivery, differing flow rates, and very different mobility needs. The ATS 2020 clinical practice guideline reflects this. It makes a strong recommendation for long-term oxygen therapy of at least 15 hours a day in COPD or ILD patients with severe chronic resting hypoxaemia, and conditional recommendations for ambulatory oxygen in patients with severe exertional hypoxaemia. It goes further, making a conditional recommendation for portable liquid oxygen in patients who are mobile outside the home and need more than 3 L/min of continuous flow on exertion.

The clinical point beneath the recommendations is simple: "oxygen" is not one generic intervention. The delivery system has to be matched to the patient. Stated as a principle:
The device should follow the prescription. The prescription should never be forced to fit whatever device happens to be available.
What the doctor assumes is happening — and what happens at home
This is where the gap becomes measurable. In a qualitative study of COPD patients who had been prescribed ambulatory oxygen, researchers interviewed 27 community-dwelling patients using prescribed ambulatory systems and found that only one of them was able to carry and use the system independently, in the way the prescriber had envisaged. The reasons were strikingly practical: patients had received no instruction on how to use the oxygen, were uncertain of its benefit, feared the cylinder running out while they were away from home, were embarrassed to be seen using it in public, and could not physically carry the equipment because of its weight. BMC Pulmonary MedicinePubMed
A national patient survey points the same way at scale. The ATS Nursing Assembly surveyed nearly two thousand oxygen users, and 51% reported problems with their oxygen — most commonly equipment malfunction, a lack of physically manageable portable systems, and a lack of portable systems capable of higher flow rates. Forty-four percent said inadequate portable oxygen limited their activities outside the home. Patient Perceptions of the Adequacy of Supplemental Oxygen Therapy.

The insight that follows is one every referring specialist should sit with:
Non-adherence is not always refusal. Often the system around the patient has made adherence unnecessarily difficult.
A clinician who writes an ambulatory oxygen script reasonably assumes the patient is now leaving the house with oxygen. In reality, that oxygen may be sitting unused in a cupboard. That disconnect is clinical, not administrative.
Patient education is part of the therapy, not an optional add-on
The ATS guideline does not treat education as a courtesy. It includes a best-practice statement that patients and their caregivers receive instruction and training on the use and maintenance of all oxygen equipment, plus education on oxygen safety — including smoking cessation, fire prevention and tripping hazards. Guideline Central
Proper education is not "here is the machine." It covers what the prescription means and when oxygen should be used; how the device operates; how tubing and cannulae are handled; how a portable system works; basic troubleshooting; oxygen and fire safety; cylinder or battery planning; and a clear contact when something goes wrong.
How often does that actually happen? In the ambulatory-oxygen study, 25 of the 27 patients could not recall receiving any instruction on using their system from a healthcare professional. And in the national survey, when instruction was given at all, it came from the equipment delivery person 64% of the time and from a clinician only 8% of the time, while 10% of patients received no instruction, and roughly a third felt
unprepared to operate their equipment. Ambulatory oxygen: why do COPD patients not use their portable systems as prescribed? A qualitative study | BMC Pulmonary Medicine | Full Text +2
That single finding reframes the whole problem. If most real-world oxygen education happens at the point of delivery, then the quality of the delivery and setup visit is not a logistics detail. It is the moment the therapy is either enabled or lost.
Portable oxygen: the difference between prescribed and usable therapy
Ambulatory oxygen has specific indications and must be prescribed appropriately — the evidence supporting it is conditional, not universal, and this is the clinician's call. But once ambulatory oxygen is indicated, the practical usability of the device matters enormously, because an unusable system delivers nothing.
The lived-experience evidence is blunt about why patients abandon portable oxygen: the weight of the cylinder was cited as a barrier by 25 of the 27 patients, 21 disliked being seen using it in public, and fear of the system running out was common. These are not clinical objections. They are design and support failures that quietly convert a valid prescription into a non-therapy. BMC Pulmonary Medicine
The clinical question is not only whether portable oxygen has been prescribed. It is whether the patient can realistically incorporate it into daily life.
That is where lighter portable oxygen concentrators, sensible rental or purchase options, and honest guidance on what a patient can actually manage stop being a sales matter and become part of whether the therapy works at all.
The specialist should not have to become the oxygen administrator
Home oxygen carries an administrative tail: qualification criteria, documentation, medical-aid authorisation and renewals, and back-and-forth with the equipment supplier. A CHEST review of strategies to improve supplemental oxygen care identified exactly these frictions — burdensome testing, prescription and documentation requirements, difficult interactions with equipment suppliers, and uncertainty about adherence — as major barriers clinicians face in delivering good oxygen care.
The division of labour should be clean. The specialist's role stays clinical: diagnosis, indication, prescription, review, and adjustment where clinically appropriate. The service partner should absorb as much of the non-clinical pathway as possible — processing the script, medical-aid administration, patient communication, equipment coordination, delivery, setup, ongoing support, routine servicing, and the documentation required for supply.
Doctor scripts. We manage the pathway around it.
Delivery is a clinical handover, not a courier event
If most patient education happens at delivery, then whoever walks into the home is doing implementation work, not fulfilment. That visit reveals things no prescription can: where the concentrator will sit, whether the patient understands the cannula, whether tubing creates a trip hazard, whether the electrical supply is sound, whether the family understands the therapy, whether anyone is smoking in the home, and whether the patient can physically manage a portable system.
This is why the ATS guideline ties equipment training and safety education — smoking, fire, tripping hazards — directly to the patient's own environment. A handover done properly is where adherence is built. A handover treated as a drop-off is where it is lost.
Delivery should be treated as part of implementation, not the end of a transaction.
Reassessment matters, because oxygen requirements are not static
A patient started on oxygen after an acute illness may not need the same therapy months later. Guidelines and expert reviews consistently stress reassessing oxygen requirements over time, particularly after a hospital discharge.
A service provider has no business changing a prescription. What it can do is keep the pathway connected — flag when a review may be due, make it easy for the treating clinician to stay in the loop, and ensure the patient does not simply drift on a script that has outlived its assessment.
The service provider supports continuity. The prescribing clinician retains the clinical decision.
What pulmonologists should expect from a modern oxygen partner
Rather than a generic checklist, the standard is best expressed as five questions a specialist should be able to put to any oxygen provider:
Can you implement my prescription accurately — the right delivery system at the right flow, not a default?
Can you educate my patient properly, including caregivers, on use and on oxygen safety?
Can you supply equipment matched to the patient's clinical and practical needs, including realistic portable options?
Can you support the patient after delivery, when the real questions surface?
Can you reduce the administrative burden on my practice while keeping me clinically in control?
If the answer to those is yes, the provider is no longer an equipment supplier. They are part of the care pathway.
The Respocare model: Oxygen as a Service
This is the thinking behind how we work. Respocare's role begins once the clinician has made the clinical decision — and from there we carry the pathway: script processing and medical-aid administration; patient and caregiver communication; home delivery, setup and in-home education; stationary oxygen; portable oxygen for rental or purchase; ongoing equipment support and servicing; backup cylinder supply; and continuity of service over time.
We work alongside specialists rather than attempting to stand in for the clinical relationship. The physician determines the therapy. Our responsibility is to make that therapy workable in the patient's real life.
A short patient journey
A pulmonologist prescribes oxygen for a patient who has recently returned home. The script reaches Respocare. The medical-aid administration is handled. The family is contacted before anything is delivered. The appropriate equipment is organised, set up in the home, and the patient and their caregiver are shown how to use it — properly, not in passing. Questions come up in the first few days, and there is someone to answer them.
Later, the patient wants to leave the house more often. Portable options are explored against the prescription and the clinical requirement, not sold ahead of it. If a clinical question arises, the patient is directed back to the treating physician. The pulmonologist remains the clinician. The patient remains supported. And the oxygen service does what a healthcare service should: it keeps the care pathway connected.
Oxygen is a therapy. Service determines how well that therapy reaches everyday life. The future of home oxygen should not be defined by who can deliver a concentrator fastest — but by who can build a reliable bridge between the specialist's clinical decision and the patient's daily reality. The prescription starts with the doctor. Good oxygen care continues long after it leaves the practice.
