Good HOOF (Part A) guide for Primary Care and Out of Hours teams Nov 2020 Update
This guide will support non-specialist teams who need to order home oxygen for palliative and cluster headache patients (normally following a consultant recommendation and not already under the care of a Home Oxygen Assessment and Review [HOS-AR] team). All other oxygen requirement should be referred to a specialist HOS-AR team. To ensure the patient fulfils the criteria for long term or ambulatory oxygen therapy – LTOT/AOT.
Produced on behalf of the National Home Oxygen Safety Group.
This guide will support those who need to order home oxygen for palliative and cluster headache patients (normally following a consultant recommendation and not already under the care of a Home Oxygen Assessment and Review [HOS-AR] team).
NB All other oxygen requirement should be referred to a specialist HOS-AR team to ensure the patient fulfils the criteria for long term or ambulatory oxygen therapy – LTOT/ AOT.
On average, a GP will fill in a HOOF once every 5 years, so this guide is to help ensure it is completed correctly first time.
If your patient is palliative, please review the guidance from the BTS before requesting oxygen or refer to local palliative care guidance where available.

BTS Guideline for Home Oxygen Use in Adults
“The term ‘palliative oxygen therapy’ (POT) refers to the use of oxygen to relieve the sensation of refractory persistent breathlessness in advanced disease or life-limiting illness irrespective of underlying pathology where all reversible causes have been or are being treated optimally.”
Studies show little benefit of oxygen therapy compared with air in either hypoxaemic or non-hypoxaemic palliative patients. This guidance therefore is for patients with:
cancer or end stage cardio-respiratory disease, on maximum treatment for underlying diseases where possible, and reversible causes for breathlessness have been or are being treated optimally, who are still experiencing intractable breathlessness, and who are either
- Hypoxaemic – resting SpO2<92% or
- Normoxaemic – but only for whom ALL other approaches have been exhausted
Before consideration of oxygen therapy:
- Ensure psycho-social factors have been assessed and addressed as distress from breathlessness can be multi-dimensional
- Trial non-pharmacological measures, including breathing relaxation and life modifying strategies, by involving physio and occupational therapists
- Trial a hand-held fan
- Assess response to Opioids (significantly better than POT in reducing the intensity of dyspnoea in non-hypoxaemic or hypoxaemic patients. Evidence level 1)
- Check SpO2 using pulse oximetry at rest and/ or after exertion.
APPENDIX 3: ASSESSMENT PROTOCOL FOR PALLIATIVE OXYGEN page i35
There is no consensus for the correct clinical assessment strategy for the use of oxygen in palliative care, although multiple tools exist for assessing dyspnoea. This assessment applies to:
The subjective severity and intensity of breathlessness should be recorded regularly to evaluate the degree of suffering caused and the effect of treatment. Recurrent assessment is prudent, especially when using an N=1 approach, as it is difficult to predict which patients will benefit (1). The Numerical Rating Scale (NRS) from 0 to 10 (0=no shortness of breath, 10=worst shortness of breath imaginable) is recommended as it was used in evidence cited. Treatment should focus on patients with an NRS ≥4, and especially those with scores ≥7.
As distress from breathlessness is not correlated to degree of hypoxemia. It is suggested therefore that oxygen flow rates be determined by symptom score on an individual basis rather than SpO2 reading (though caution is advised with this approach as cool air can relieve breathlessness which is why hand-held and other fans are useful and sometimes a lower flow rate plus a fan provide effective relief). Additional consideration needs to be given to potential risks of hypercapnia in those patients susceptible (commonly COPD and those with neuromuscular disease – see BTS guidance for detail) if oxygen is given at higher flow rates.

The recommendations in this document relate to patients with COPD. After discussion with part of the committee who wrote the guidelines, the safety considerations and smoking recommendations could stand regardless of disease prognosis.
Concentrator or cylinder as determined by patients’ needs. If the need is intermittent, then static cylinders may be considered. If it is considered, however, that the patients’ needs are going to increase to >4 hrs a day, then a static concentrator should be first choice.
NB Oxygen cannot be stored in the body, so using it pre-exertion to ‘stoke up’ is unhelpful; likewise, replacing lost oxygen post exertion is unnecessary as levels will normalise with rest anyway, so the perceived desire for a ‘few whiffs’ here and there, pre or post exertion, is not an indication. Hypoxaemia on exertion should be managed with AOT.
The NHS pays for every delivery of static cylinders and so, if a patient deteriorates, a new HOOF may be required, or the patient may have to keep ordering urgently, which is both an added stress at a difficult time for the patient and their family, and adds to the £108M (Correct 2018) National home oxygen bill.
Oxygen therapy, like any pharmacological intervention, should be best considered on a trial basis and be reviewed regularly, while balancing benefits and risks. Most benefit is likely to occur in the first 24 hours, and nearly all symptomatic and functional improvements within the first 3 days of use (1). Follow-up and assessment of response should fit with these timescales.
If the patient still requires oxygen, both a consent form and the Initial home oxygen risk mitigation form (IHORM) need to be filled in and signed before oxygen is requested. (There is a guidance document and a FAQ for the new consent form). All the documents for a GP or OOA team are below. Some areas will have these forms already uploaded onto local systems e.g. EMIS

Some Suppliers encourage you to use their portal see local contact details on 5/6. Other suppliers request that you email the hoof on a named nhs.net address.
Please note from the roll out of the new contract in 2020 across most of England and Wales the use of Faxes is no longer acceptable.
Section 1 and 2: Patient and Carer Details
Please fill in all the boxes, with particular attention to including NHS number and contact details.
Section3: Clinical Details
Complete the clinical coding to assist in data management and on-going reviews to provide an integrated care plan for the patient where required. Clinical Code definitions can be found in section 14 of the HOOF Part A and are now mandatory from 1st August 2017. On the very rare occasion where the patient is using NIV/CPAP or is a paediatric patient, it is recommended that you refer to their Respiratory Clinician/Paediatrician.
Section 4: Patient’s Registered GP Information
Enter the details of the GP with whom the patient is registered.
Section 5: Assessment Service (Hospital or Clinical Service)
Please complete the details of the Assessment Service that will be used for follow-up purposes. This enables us to communicate effectively and ensure seamless care for the patient. Prompt communication with specialist assessment centres/specialist respiratory teams will ensure that they are informed of the situation and are able to assess the patient at the earliest opportunity.
Section 6: Ward Details (if applicable)
If the patient is in hospital and due for discharge, section 6 should be completed. This will enable us to liaise with the hospital to ensure a smooth and consistent process with minimal delays disruptions.
Sections 7, 8, 9: Ordering
Section 7 relates to the oxygen the patient should use. The flow rate of oxygen needs to be stated, together with the number of hours of therapy required per day. All parts are marked as mandatory; failure to complete in full will result in potential rejection and ensuing delay in the provision of supply.
The flow rate must be given as litres per minute. If a fractional component is required (e.g. 0.5,
1.5 LPM etc.) please ensure the decimal point is clearly marked. There should also be a digit to the left of the decimal point (e.g. 0.5 rather than .5).
The period of use required to meet the patient’s need must be stated in hours per day, although periods of less than one hour can be expressed in minutes (e.g. 15 minutes or 15 min).
Section 8 – The choice of equipment will ideally be based on a) the flow rate b) period of use and c) expected length of treatment.
Ultra-high flow rates (> 12 LPM) are generally provided via cylinder supply, particularly if period of use is short (e.g. 15 – 20 minutes per day) Cluster headache patients are the most common patients to require static cylinders at these ultra-high flow rates.
- Lower flow rates and short periods of use (e.g. 1.5 LPM for 1hour per day) will generally best be provided via cylinder supply
- Longer periods of use (e.g. above 4 hours per day) will generally best be provided via concentrator supply
- Where the supply is likely to be in situ for a short period of time (e.g. a few days), with a consistent modest flowrate and period of use, again cylinder supply may be best, but if there is a concern that usage is going to increase, then a concentrator should be considered, to save the family and patient from extra stress at this difficult time.
The quantity to be ordered will depend on flow rate (concentrators) or flow rate & period of use (cylinders), please consult your home oxygen supplier.
For section 9, a choice of either nasal cannula or mask should be made. Most patients would use a nasal cannula unless there are issues with mouth breathing, the home oxygen supplier should be able to give advice. For Cluster headache patients a 100% non-rebreather mask is the default mask.
Section 10: Delivery details
Please indicate the delivery timescale required. Be aware that there are cost implications if using other than standard delivery times.
Section 11: Additional Patient Information
If you would like the oxygen assessment centre to review the patient within a timescale, please indicate which month and year the review would be required. For example, write “Review: April 2020”. If no date is specified, we will notify the assessment centre to review the patient in 6 months’ time.
Additionally, this section should be used to advise us of any special information relating to the patient’s oxygen supply and on-going support requirements. This could include, for exa[mple, physical disabilities, language difficulties, non-English speaker.
Section 12: Clinical Contact (if applicable)
The details of the clinical contact for the patient need to be incorporated here. It is possible that this may be the same person signing the HOOF Part A and, in this case, those details must be repeated here.
Section 13: Declaration
This declaration is mandatory and must be fully completed before the HOOF Part A is sent to the supplier. Both the Consent form and IHORM must be filled in and ticked.
For all new patients, these forms must be signed off appropriately by the clinician and the patient/ patient’s representative. If it is any existing patient please confirm with the patient that the forms were signed previously and it maybe in their notes.
It is very important that not only is the declaration signed, but also a NHS email address or an approved secure email is provided so that we are able to send confirmation/corrections back.
Section 14: Clinical Code:
This must be added to Section 3 as it is a mandatory requirement
We would strongly advise that ‘Referred for Assessment’ boxes are completed and, if
possible, send both forms to your local home oxygen teams for follow up.
If the patient has passed away then this can be called through to the supplier by family or carers.
Otherwise an email should be sent to the supplier to request removal by an HCP.
If oxygen is removed as it is no longer clinically appropriate, the patient does not want to use it, or following failure of a risk assessment, an email should be sent to the supplier to request removal by an HCP after agreement with the prescriber, the local HOS team or GP.
