An App Platform-Facilitated Collaborative Palliative Care Intervention for Outpatients With Interstitial Lung Disease: A Pilot Randomized Trial.

Outpatients with interstitial lung disease often experience serious symptoms, yet infrequently receive palliative care. To determine the feasibility and clinical impact of a mobile application (PCplanner) in an outpatient setting. We conducted a pilot randomized controlled trial among adults with interstitial lung disease in a single-center academic clinic. Clinical outcomes included change in Needs at the End-of-Life Screening Tool (NEST) scale between baseline and 3 months as well as frequency of advance care planning discussions and referrals to palliative care services. Observed feasibility outcomes were similar to targeted benchmarks including randomization rates (82.1% vs 80%) and retention (84.8% vs 80%). Mean NEST scores between the intervention and control group were 38.9 (SD, 18.9) vs 41.5 (SD, 20.5) at baseline, 34.6 (SD, 18.9) vs 33.6 (SD, 19.4) at 1 month after clinic visit, 40.5 (SD, 21.6) vs 35.3 (SD, 25.0) at 3 months after clinic visit. Changes in NEST scores between baseline and 3 months showed no difference in the primary outcome ( = 0.481, 95% CI [-8.45, 17.62]). Among patients with interstitial lung disease, a mobile app designed to focus patients and clinicians on palliative care principles demonstrated evidence of feasibility. Although changes in self-reported needs were similar between intervention and control groups, more patients in the intervention group updated their advance directives and code status compared to the control group.
