Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention is the implementation of the Breathless Clinic (BC), a nine weeks’ programme to manage refractory breathlessness. The intervention duration is planned for a period of 12 months, so as to minimise the impact of seasonal variation on our results. The follow up duration comprises 12 months (from initial enrolment in clinic).
Following assessment, review and optimisation of pharmacotherapies, non-pharmacologic treatment interventions will commence and further investigations and referrals will be undertaken as required. The most crucial aspect of BC, is to provide coaching for dyspnoea self-management and daily coping strategies for survival in the domestic setting or community; for example, breathing techniques, posture, fans and self-talk (offered through senior specialist respiratory nursing colleagues) and the strategies provided to improve efficiency and therefore manage breathlessness during day-to-day activities, tailored for individual patients in the home setting, by our physiotherapy and occupational therapy clinicians. These aspects may allow for greater independence and participation in community activities. "Home visits" and standard clinic visits will usually occur face to face but may also utilise telephone or videoconference depending on the patient circumstances and preferences.

Non-pharmacologic breathlessness interventions (examples):
Beliefs
• Validation of breathlessness
• Clarifying mistaken beliefs (breathlessness is not always due low oxygen levels, breathlessness itself is not dangerous)
• Motivational interviewing

Strategies
• Hand-held, battery-operated fan
• “Breathing around the rectangle”, “flickering the candle” (single breath)
• Other breathing techniques (breathing pattern) – paced or diaphragmatic breathing, “blow as you go”
• Positions to relieve breathlessness

Training
• Walking program (supported by use of a pedometer)

Aids/efficiency
• four-wheel walker/ shower chair
• Energy conservation (save energy on what you must do, so that you have some spare to participate in activities that you enjoy).
• Home modifications
• Referral to dietitian if underweight/ malnourished

Education and Self-management
• Written breathlessness action plans* (3 Fs - lean Forward, Focus on breath out, Fan; 3Ps - Pause, Purse lips, Position)
• Written COPD exacerbation action plan** (guide of what to do in an exacerbation)
• Breathlessness DVD*** – reinforces key interventions to relieve breathlessness
• Relaxation CD***

Miscellaneous
• Sputum clearance techniques
• Carer support
• Management of incontinence

BC schedule
The clinic itself comprises eight to nine healthcare interactions over nine weeks, with most interactions occurring within the patient’s home;

Week 1 (patient’s home) – Initial assessment, Respiratory Nurse, research assistant
Week 2 (outpatient clinic) – Formulate Management Plan, Multidisciplinary Team
Week 3 (patient’s home) – Physiotherapist
Week 4 (patient’s home) – Occupational Therapist (as required)
Week 5 (patient’s home) – Respiratory Nurse
Week 6 (patient’s home) – Physiotherapist
Week 7 (patient’s home) – Respiratory Nurse
Week 8 (patient’s home) – Final assessments, research assistant
Week 9 (outpatient clinic) – Closure and follow up arrangements, Multidisciplinary Team

Clinical items to be reviewed/assessed at BC visits 1 and 2
1) Heart rate, blood pressure, respiratory rate and oxygen saturation
2) Electrocardiogram (ECG)
3) Height and weight
4) Most recent measures:
a) spirometry or complex lung function within previous 12 months
b) inflammation (white cell count and differential, C-reactive protein) within previous 12 months
c) cardiac biomarkers (high sensitivity Troponin T, NT-proB-type Natriuretic Peptide) within previous 12 months
d) microbiology (any positive gram stains, cultures and available antibiotic sensitivities, any positive respiratory viral screens within previous 12 months)
e) 6 minute walk test (6MWT), if available, within 12 months
5) Comorbidities and current medications
6) Mini Nutritional Assessment (MNA)
7) Eating Assessment Tool (EAT-10)
8) Exacerbation history
9) Healthcare visit data
10) COPD action plan

Clinic team: Specialist Respiratory Physician, Specialist Respiratory Nurse, Senior Physiotherapist (with experience running pulmonary rehabilitation program), Senior Occupational Therapist.
The clinic team will deliver the intervention as per the clinic program above. The team may also include general practitioner, senior registrars in Cardiology and Respiratory Medicine

All clinic interactions will ideally involve a single participant and their partner/carer (if relevant). The sessions will last 30 - 120 minutes.

Since BC is part of the clinic services of our hospital, each clinic interaction will be recorded within each subject's electronic medical record (EMR). Compliance for some individualised BC components will be assessed (for example step counts measured by pedometer for patients receiving exercise recommendations to achieve a goal daily step count). However, for the most part, the assessment of adherence to clinic recommendations will be subjective (by patient report) and captured during the post-clinic interviews collecting qualitative data, along with the patients' perception of which clinic interventions were most and least helpful for managing their breathlessness.

* Written breathlessness action plans, resources originally developed by Cambridge Breathlessness Intervention Service and distributed via their education seminars, then adapted for use in Westmead Hospital's breathlessness clinic service (used with permission)
** COPD action plan, readily available free resource from Lung Foundation Australia, routinely used in clinical practice
*** Breathlessness DVD, developed for breathlessness clinics at Westmead Hospital and used with permission.
**** Relaxation CD, developed for breathlessness clinics at Westmead Hospital and used with permission.

Note: Westmead Hospital's Breathlessness Clinic service has provided collaboration and mentorship in developing/designing the clinic used in this intervention, which has been adapted to the Campbelltown Hospital setting.

Comparator / control treatment
The control is "standard care" which may involve pulmonary rehabilitation, general practice review, outpatient specialist clinic review, community nursing involvement.
Participants will act as their own controls, with breathlessness impact data being compared with baseline and health outcome data (from the previous 12 months) being compared with the 12 months from commencement of protocol.
Benchmarking with similar or theoretically comparable populations will also be applied, where appropriate, for healthcare outcomes:
1. comparison of unplanned admission rates and unplanned hospital bed days within the year of the study with the corresponding figures for a population comprising all patients hospitalised within Campbelltown Hospital with diagnostic related group (DRG) code "COPD" during the 12 months prior to BC commencement (study participants excluded).
2. comparison of unplanned admission rates and unplanned hospital bed days within the year of the study with the corresponding figures for population comprising all patients presenting to Campbelltown Emergency Department with the triage category "SOB respiratory" (Shortness of breath, respiratory) during the 12 months prior to BC commencement
Study participants will be excluded from populations used for benchmarking.

Qualitative analysis
Perspectives from patients and carers, based on their experiences of BC, will be explored via interview and analysed using qualitative thematic analysis to identify key concepts and themes. Patients and carers (if applicable) will be interviewed together. We will seek feedback from the consumers involved in the BC intervention, using qualitative research to develop a deeper understanding of their experience, which can be used to inform interpretation of trial outcomes and further refinement and adaptation of the intervention for other settings.
Interview will generally be face to face, although there is provision to undertake the interviews via telephone or videoconference medium, depending on the participants' circumstances and preferences.
Timepoint [14] 388212 0
Consumer feedback will be sought at conclusion of the BC intervention and take the form of a standardised semi-structured interview (10-18 weeks).

Intervention assignment
Single group
Other design features
All participants receive the same intervention throughout the study.
For the primary outcome and most secondary outcomes, the participant results post intervention will be compared to those obtained at baseline (subjects will act as their own controls).
The study's qualitative component will explore perspectives from patients and carers, based on their experiences of BC, to identify key concepts and themes and to inform future adaptations of the clinic model.
Some secondary healthcare outcomes will be benchmarked (see previous sections) against populations in which outcomes might be expected to be similar, such as "patients admitted with DRG code COPD" and patients triaged in the Emergency Department as "SOB - respiratory". However, benchmarking is not being undertaken for the primary outcome and so such analyses should be regarded as "exploratory".

Efficacy
Statistical methods / analysis
Breathless Clinic (BC) will be evaluated by means of a pre- and post-intervention study, with subjects acting as their own controls, before and after the clinic intervention duration of nine weeks. Twelve months’ follow up data will provide further information about the sustainability of outcomes.
Recruitment target estimation is constrained by limited precedent data, We have estimated sample size for this study on limited data from one small study of a population similar to our own, and other study populations comprising patients with refractory dyspnoea but quite different from our own. Considering these data, we have set our BC recruitment goal at 92 subjects, in anticipation of 30% discontinuation or dropout.
The subject group will be characterised by application of descriptive statistics to clinic baseline data collected prior to the first hospital visit.
The clinical effectiveness outcome measures (breathlessness impact) will be repeated at clinic completion and 12 months to compare with the baseline assessments, assessing for any effect of the BC intervention and whether that effect is sustained. Healthcare outcome data for BC patients will be compared with that for the previous 12 months and benchmarked, where appropriate. For continuous data, statistical comparison will be undertaken using T tests, provided that the data is normally distributed and subject to normal transformation prior to analysis if they are not. Comparisons will be made between baseline and 9 weeks (BC completion); baseline and 12 months, 9 weeks (BC completion) and 12 months. Categorical data will be compared using Chi squared or Fisher’s exact test, as appropriate. Subjects' compliance/fidelity with individual components of the BC intervention will be correlated with clinical and healthcare outcomes, in an attempt to determine which components are the most important contributors to outcomes.
