5. Background (I)
• REG’s focus is real-life research
o Raising the quality and profile of real-life research methodologies
o Using real-life research to address unmet research needs and
address gaps in the evidence base
• Efficacious IPF therapies resulted interest in a need to better
understand the reality of ILD diagnostic practice to optimise
treatment outcomes
• Initial concept – utilise the REG ILD Working Group network to
conduct a diagnostic agreement study:
o Discussion around variability in diagnostic agreement within ILD.
o Would a range of MDTs within this network agree on the
diagnoses if given the same set of “test cases”
6. Background (II)
• Questions when designing the agreement study:
o What would be appropriate definition of an MDT?
o What would be the right case mix for inclusion?
o What does real-life diagnostic practice look like?
• There is limited knowledge of how diagnosis takes place
outside specialist centres
• As a precursor to evaluating agreement, it’s necessary to
understand how ILDs (in particular IPF) are diagnosed in
routine care
7. Agreement Study: Phase I Outputs
• Characterise the ILD diagnostic process globally,
especially in countries/territories where little is currently
known.
• Provide valuable insight as to current diagnostic
practices to inform the robust design of Phase II.
• Develop a characterised global network of ILD centres
for engagement in Phsae II and future research:
o The Phase II diagnostic agreement/accuracy study
o Future ILD and IPF research (RCT and real-life studies)
8. Outputs: Phase II
• Evaluate agreement and accuracy of ILD MDT
diagnosis across a range of global sites and healthcare
settings
• Identify features of current MDT diagnostic practice
associated with accurate diagnosis (including the
effect of bronchoscopic sampling for diagnosis)
• Produce a series of best practice recommendations to
optimise the pathway to accurate ILD diagnosis for future
practice.

12. Centre Recruitment: principles (I)
• Centre Inclusion: Not restricted to expert / specialist centres; a broad a
range of different diagnostic settings will be included
• Objective: The study will help to characterise and describe range and
variation in diagnostic practice
• Local Expertise: Local experts will guide participation in their country to
ensure a range of relevant healthcare settings / centres are included
• Descriptive study: No conclusions about practice approach prevalence
(e.g. what is ‘usual practice’) will be made, i.e.:
o A range of centers in each country is required to reflect the variation
in practice within each country
o The selection of participating centers does not need to be
representative of practice in that country, overall
13. Cascade Approach
• Regional Leads will be asked to:
o Provide country lead names
• Country leads will be asked to to:
o Advise as to translation requirements
o Support translation(s) (personally, or nominate colleague)
o Forward to a number of ILD Centres known to them
• Participating centres will be asked to:
o Complete the questionnaire
o Send it to other centres in their network

16. Example approach – Latin America
• Registry efforts in recent years have identified lead contacts for most
countries in Latin American (except Bolivia) and Central American
• Each national lead can be contacted and asked how they would
envisage contacting their national peers e.g.:
o What resources would they use to identify participants and email addresses,
o How many contacts they have
o How they would recommend we contact those centres)
• Invitations can then be sent to a number (e.g. 20-50) of centres in
each country along with the questionnaire link and a cover note
outlining the broad objectives of the study
• Turnaround should be relatively rapid and feasible within the
proposed 2-month data collection period
• Translation will be important, especially in Brazil, but should be a
minor effort to implement
17. Identification of Country Leads
& Participants
Help us to:
– Identify National Leads
– Translate the questionnaire
18. Translations
• Local language translations will be offered as:
o Necessary in some countries
o Desire standardization of approach across all countries (i.e. translate for all not some)
• Translation support required:
o Preliminary translations can be provided for the following languages, but review and
tailoring will be required by a native speaker:
– English – UK; Esperanto; Estonian; Finnish; French; German; Greek; Gujarati; Hebrew; Hindi; Hungarian; Italian;
Japanese; Khmer; Korean; Latvian; Lithuanian; Macedonian; Mongolian; Myanmar; Norwegian; Persian; Polish;
Portuguese; Romanian; Russian; Serbian; Slovak; Slovenian; Spanish (Latin America); Spanish (Spain); Swahili;
Swedish; Tamil; Thai; Turkish; Ukrainian; Urdu; Vietnamese; Welsh
– Test (in Italian) suggests preliminary translation is ~80% accurate
– Text will be provided in a Word Document that can be edited / corrected
o Where a preliminary translation is not possible; a native speaker must be identified to
support
• Questions are clear and straight forward, so forward translation only will be sufficient

21. Look back to move forwards
• Time to look upstream…:
o What happens to patients in the lead up to their diagnosis
o Are opportunities for earlier diagnosis being missed in primary care
o How can non-specialists be supported to help identify potential IPF and
earlier referral to specialist care…?
• Identify common patterns (trends) in healthcare resource utilization
(HRU) and identify potential “red flags” to to aid earlier diagnosis

22. REG ILD WG Study Aims
• With a view to identifying potential opportunities for earlier
referral to specialists and (ultimately) earlier diagnosis of
IPF, the study aims to:
1. Characterise the clinical features of patients at the time of
their IPF diagnosis
2. Evaluate patients’ patterns of HRU in the years preceding
their IPF diagnosis
3. Develop optimum code lists for IPF database research, i.e.
variation in 1 & 2 for sensitive versus specific code lists

29. Characterization at IPF Diagnosis
Patients will be stratified by broad vs specific IPF code and
characterized in terms of:
• Demographics
• Lifestyle factors
• Comorbidities: Respiratory, Other
• Obstructive lung disease (OLD) pharmacotherapy in the year
preceding index date
• Symptom severity (mMRC)
• Lung function (FVC, FVC %pred, FEV1, FEV1/FVC)
• Obstructive lung disease characteristics:
o COPD GOLD status
o Blood eosinophilia (≥0.5 x 109/ L)
30. Outcomes: trends in HRU
• Consultations:
o Lower respiratory (LR)
consultations
o LR Consultation resulting in a
course of antibiotic drugs (on the
same day)
o LR Consultation resulting in a
course of oral steroids (on the
same day)
• Hospitalisations (in-patient
attendances) with a code for a:
o LR complaint on the same day
o LR complaint within 14 days
• Chest X-ray / radiology
• Cough
• Therapies
o Prescriptions for antibiotics
o Prescriptions for oral steroids:
– Acute
– Maintenance
• Emergency Room / Accident &
Emergency (A&E) attendances
coded for a:
o LR complaint on the same day
Longitudinal trends in HRU preceding IPF diagnosis:
• 10-year annual trends
• 2-year quarterly trends (last 2 years before diagnosis)
33. Clinical features of patients at the
time of their IPF diagnosis
In this routine care IPF population from the UK:
• Demographics
o Mean age: 72-73 years
o Men accounted for 62-65% of the population
o Approximately 1/3 were never smokers; 2/3 current or ex-smokers
• Comorbidities
o 13-25% had obstructive lung disease (13-15% asthma; 19-25% COPD)
o Approximately 50% of patients:
– Had cardiovascular disease (46-53%)
– Consulted for cough (40-52%; ~10% in the 2 years preceding IPF diagnosis)
• Respiratory therapies
o 18-26% of patients received ≥1 prescription for SABA in the year preceding
IPF diagnosis
o Prescribing of all other obstructive lung disease therapies (ICS, LABA,
LAMA, combinations) was low (<10%)
34. Patterns of HRU in the years
preceding their IPF diagnosis
• All markers of respiratory HRU increased annually over
the 10-years and quarterly within the last 2 years leading
up to patient’s IPF diagnosis:
o Primary care events
– LR consultations, LR antibiotics and oral steroids (acute and
maintenance)
o Secondary care attendances
– Hospital admissions, Out patient department attendances,
Accident & emergency attendances
o Other:
– Cough events, Chest X-rays, Incidence of pneumonia
35. Code lists: specific vs broad
• Compared with patients with a “specific” IPF diagnostic code, those with a “broad”
diagnostic label were similar in terms of their:
o Demographic presentation at the time of diagnosis
o Escalating trends in HRU in the years preceding IPF diagnosis
o Lung function: Similar mean(SD) FVC: 3.1(6.8) vs. 2.5(0.9) (p=0.405)
• Comorbidities broad IPF patients had:
o Similar burden of:
– Chronic respiratory conditions (incl. asthma; excl COPD); heart failure,
rhinitis, bronchiectasis, eczema, osteoporosis, cerebrovascular disease,
sleep apnoea, depression and anxiety
o Higher burden of :
– COPD, cardiovascular disease, ischaemic heart disease, Hypertension,
diabetes, myocardial infraction, GERD,CKD, lung cancer, cough
• Drug usage: broad IPF patients had higher use of short-acting bronchodilator therapy
in the year preceding IPF diagnosis (26 vs 18%)
