Such interventions may be effective in other patients e.g. interstitial lung disease (ILD) or post lung transplantation (pLTX) if patients have similar attitudes towards PA.Aim: Compare characteristics of patients with COPD, ILD and pLTX starting tele coaching to improve PA.Methods: Patients with COPD, ILD and pLTX were included when starting TC. A 6-minute walking test (6MWT) and the Hospital Anxiety and Depression Scale (HADS) were completed and social status was recorded. Importance, motivation and self-efficacy to improve PA were scored by the patient on a 10-point scale. Groups were compared using ANOVA or Wilcoxon tests.Results: Patients pLTX were younger and had a lower BMI (table 1). Gender, HADS, marital status, importance of and motivation for PA did not differ between groups. Patients with COPD had a better 6MWT than patients pLTX and their self-efficacy to improve PA was higher than patients with ILD and pLTX.Conclusions: Lower self-efficacy observed in ILD and pLTX is an additional challenge for PA coaching. Future studies should consider self-efficacy as a possible mediator of effect.Funding: FWO #1194320N & BI#2019/1950.FootnotesCite this article as: European Respiratory Journal 2021; 58: Suppl. 65, PA1811.This abstract was presented at the 2021 ERS International Congress, in session “Prediction of exacerbations in patients with COPD”.This is an ERS International Congress abstract.
