Concurrently, there has been an increase in clinical trials; growing research interest in patient experiences of living with IPF and the approval of two treatments. There is a growing need to reliably and consistently measure health status in this population and a need for an IPF Specific PRoM that is concordant with the European Medicines Agency (EMA) and US FDA criteria2 and UK NICE guidelines3. Aim: To develop a robust, patient centred methodological approach underpinning a patient reported outcome measure for IPF, a rare condition To identify concepts & descriptors of IPF attributes which are important to patients Results: R1: Participants (n=120) rated 329 statements on a Likert scale 1-7 (‘very’ to ‘not at all’ important) Consensus determined using criteria in Table 1. 98 items were retained for R2 and 18 additional items added from analysis of comments in R2 Repeating the process 12 items were eliminated after R2. Response rate >93%. A greater number of items than anticipated remained resulting in too high a ratio of respondents per item Development of a Round 3: Aim: to recruit 300 participants Participants were recruited through IPF charities & support groups. An electronic link to the questionnaire was hosted on the charity websites / facebook. Self-selecting participants, confirming they had a diagnosis of IPF, anonymously recorded their level of agreement / experience with 104 statements about IPF on 4 point Likert scales. Questions regarding diagnosis were incorporated to maintain authenticity of disease group IP addresses were checked to detect duplicate responses. Results of Round 3: Participants accessing survey n=510; Partially completing survey n=70; Completing survey n=281; Completing hard copy n= 20; Not required to complete survey due to a diagnosis other than IPF n=41 108 participants accessed the survey but did not proceed to the questions Years N (%) ≤59y 55 (19.5%) 60-69 109(39%) 70-79 93 (33%) range ≥ 80y 24(8.5%).

Working with IPF charities provided a feasible, reliable and an efficient way to gather a large volume of responses across the UK and Ireland in a short period of time (4 months) from patients diagnosed with IPF. This approach enables the application of appropriate psychometric analysis to these data and offers one approach for generating rich data in rare conditions Table 1: Consensus Criteria Statement result Threshold to apply Definitely include >=70% of participants rate statement as >=6 OR Median rating of >=5 Maybe include >=70% of participants rate statement as >=5 OR Median rating of >=5 Definitely exclude <70% of participants rate statement as <=4 AND 100% participants understand statement OR Median <=4 AND 100% panel understand statement Review <70% of panel rate statement as >=6 AND <100% panel understand statement References Devlin N & Appleby J Getting the most out of proms: Putting health outcomes at the heart of NHS decision-making The King’s Fund 2010 Guidance on the routine collection of Patient Reported Outcome Measures (PROMs) DH: http://www.dh.gov.uk/en/Publicationsandstatistics/Publications/PublicationsPolicyAndGuidance/DH_092647 U.S. Department of Health and Human Services Food and Drug Administration (FDA).
