The utility of an electronic health journal with home spirometry in a real world population of people with fibrotic lung conditions
ABSTRACT
Background:
Daily home spirometry in idiopathic pulmonary fibrosis (IPF) has been shown to be feasible and clinically informative. The patientMpower electronic health journal (pMp) is an application to facilitate home spirometry with the addition of home monitoring of IPF-related symptoms. pMp is downloaded to the user’s mobile phone or tablet device to enable them to record objective and subjective data.
Objective:
We report on one year’s experience of using pMp with home spirometry in 36 subjects with self-reported pulmonary fibrosis (PF) treated with usual care.
Methods:
Participants enrolled in the programme were recruited through one of two patient advocacy groups: Irish Lung Fibrosis Association, Ireland or PF Warriors, US [baseline mean predicted Forced Vital Capacity (FVC): 64% and 62%, respectively]. Participants in each population were recruited to identical open-label, single-group observational studies and were provided with a Spirobank Smart spirometer which integrated directly via Bluetooth with pMp. Data collected via pMp included: FVC (once/day; seated); breathlessness (modified Medical Research Council score), step count, medication adherence, symptoms and impact of IPF on daily life [patient-reported outcome measure (PROM) specifically developed for IPF].
Results:
Thirty-six participants used pMp and provided spirometry data. A large majority reported that using pMp was positive and wished to continue using it after an initial 6-week observation. Twenty-one participants (58%) recorded home spirometry without prompting for ≥180 days and 9 (25%) continued with recording home spirometry for ≥360 days. Longitudinal patient-reported data on breathlessness, oximetry, oxygen consumption and impact of IPF on quality of life were also collected.
Conclusions:
The pMp application with associated Bluetooth-connected devices (e.g. spirometer, pulse oximeter) offers an acceptable and accessible approach to the collection of patient-reported objective and subjective data in fibrotic lung conditions. Clinical Trial: Not registered
