Plain English summary of protocol
Background and study aims
Breathlessness is common in people with heart and lung conditions and can get very severe and frightening. When this happens patients or family members often call an ambulance, especially when their own doctor’s surgery is closed. In a recent study, it was found that 1 in 5 of all people taken by ambulance to Accident and Emergency (A&E) called for help because of breathlessness. A third of these did not need to stay in hospital and went home. There are treatments to calm severe breathlessness that could be used in the patient’s home. If paramedics can use this approach, breathlessness may be calmed more quickly and some people may not need to go to A&E. The aim is to see if it is possible to run a research study with people calling ambulances because of breathlessness. The study will test if paramedics trained in breathlessness techniques can ease breathlessness more quickly than usual care, and help more people stay at home. People with severe breathlessness have said this is important and have agreed to help run the study. At the end of this “test” study, it will be known whether i) such care can be used by paramedics, ii) a larger trial can be done and iii) the best way to run it. The researchers will let the participants, local support groups, charities, local clinicians and the funder know their findings and also publish them in a scientific journal. This study is a key first step to help people with severe breathlessness needing emergency help.
Who can participate?
Patients in their normal home environment experiencing a breathlessness crisis and receiving a 999 ambulance response from a participating paramedic
What does the study involve?
Eight paramedics in the Yorkshire area are chosen at random to use the breathing calming techniques in breathless patients or to give usual care. Patients are asked to provide consent for the use of routinely collected information from the call out and about whether there have been any further call-outs in the next 48 hours to be used in the study. They are also asked whether they are willing to be contacted about taking part in the follow-up of the study. Patients agreeing to further contact are contacted by a member of the research team about participating in the follow-up. If the patient agrees, a member of the research team visits them at a place suitable to them to gain written consent before completing an interview and/or three questionnaires. If the patient has a carer, they are invited to join the interview. The patient is contacted again at 1 month and 6 months after the original call-out about repeating the three questionnaires.
What are the possible benefits and risks of participating?
There is no specific benefit to the participants other than the potential to inform future research into the clinical practice of the ambulance service. The intervention is considered to be of low risk as it is based on best practice and optimisation of routine care.
Where is the study run from?
The study is being run by the University of Hull/Hull York Medical School and the Yorkshire Ambulance Service NHS Trust in the Yorkshire and Humber region (UK)
When is the study starting and how long is it expected to run for?

| Health condition(s) or problem(s) studied | Breathlessness as a result of either COPD, bronchitis, asthma, bronchiectasis, emphysema, heart disease or cancer in the lungs |
| Intervention | A group of paramedics (paramedic-participants) will be randomised to either deliver usual care or adopt the BREATHE intervention into routine practice for breathlessness patients. These paramedics will act as the cluster factor in a feasibility cluster randomised controlled trial: Usual care: The paramedic-participants in the control group will deliver usual care according to national guidelines including; initial history, baseline vital signs and tailored examination (chest auscultation, peak flow readings, 12-lead ECG). BREATHE intervention: In additional to usual care, patient-participants managed by paramedics-participants allocated to the intervention will receive a paramedic-administered short non-pharmacological complex intervention. This includes i) face-to-face advice (positioning, breathing techniques, panic management, fan) ii) a laminated leaflet and iii) a breathlessness management booklet to keep and refer to later. This booklet will have information to help the patient and carer self-manage breathlessness and information on local services they can turn to for support. |

Patient recruitment rate recorded as the number of eligible patients who consent to participate to Day 0 data use 2. Patient consent rate for follow-up data provision recorded as the number of patients who consent to Day 0 data use who also consent to follow-up 3. Patient attrition rate recorded as the number of patients who consent to participate in follow-up that remain in the study until the end of follow-up |
| Secondary outcome measures | Other feasibility outcomes: 1. Data quality of routinely collected and patient/proxy reported data recorded as completeness of data at Day 0 and 48-hour post-call-out data 2. Data quality of patient-reported outcomes recorded as completeness of questionnaire completion at 14 days, 1 month and 6 months 3. Intervention fidelity recorded as elements of BREATHE intervention used by the paramedic during Day 0 call-out 4. Patient adherence to the BREATHE intervention recorded as how they take part in the intervention in the call-out on Day 0 5. Acceptability of the BREATHE intervention to the patients is reported from qualitative analysis of interviews at 14 days post call out 6. Acceptability of the BREATHE intervention to the paramedics is recorded by Process evaluation and qualitative interviews at end of recruitment 7. Use of BREATHE intervention by patient since initial visit on Day 0 is reported from qualitative analysis of interviews at 14 days post call out and Health service utilisation questionnaires at 1 month and 6 months 8. Intracluster coefficient and sample size calculation for candidate primary outcomes Potential definitive trial primary outcomes: 1. Improvement in breathlessness intensity at end of paramedic visit is measured by patient-participant report or paramedic-participant proxy report NRS intensity “now” every 2 minutes till decision to transfer to ED or decision to keep at home on Day 0 2. Conveyance to Accident & Emergency is being collected from routinely collected data at Day 0 Clinical measures: 1. Paramedic routinely collected clinical and service delivery data (pulse, respiratory rate, blood pressure (systolic and diastolic), capillary blood oxygen saturation level (SPO2) with air, SPO2 with oxygen) recorded at first and last assessments of call-out on Day 0 2. Working impression is recorded as paramedic impression on Day 0 Health service utilisation: 1. Duration of index call (Day 0) is collected from routine data 2. Future call-outs in 48 hrs (routinely collected) at 14 days 3. Health service utilisation relating to the 6 months prior to Day 0 is collected by Health service utilisation questionnaire at 14 days 4. Utilisation of primary and emergency services is collected by Health service utilisation questionnaire at 14 days, 1 month and 6 months Health status: This will be measured by the SF-6D which is derived from the SF-36. The SF-6D is a validated health status measurement tool widely used in health economic evaluations. For the purposes of this feasibility study data completion will be assessed and quality-adjusted life years will not be calculated Chronic Respiratory Questionnaire dyspnoea domain: This includes measurement of mastery of breathlessness and is recommended in addition to a unidimensional tool such as the NRS. This will be measured at 14 days, 1 month and 6 months |
