Can people referred to pulmonary rehabilitation easily learn to use a system for remote transmission of oximetry data? Do they consider remote transmission of oximetry data to be satisfactory? Are the transmitted data valid compared with locally stored data?Multicentre, prospective, observational study.One hundred and five adults with chronic respiratory disease who were referred to pulmonary rehabilitation.At an initial session, participants were taught to record and transmit their oximetry data to a remote server. At subsequent testing session(s), participants were requested to independently activate and use the oximetry monitoring system for a period of exercise on a cycle ergometer, until autonomy with the system was demonstrated. A subgroup of five participants undertook five 45-minute training sessions to generate a dataset to assess whether the transmitted data were valid compared with the locally stored data.Outcome measures included the number of sessions needed to become autonomous, participant satisfaction with the system, and measures of the validity of the transmitted data.Participants became autonomous quickly: 86% at the first testing session and 100% within three testing sessions. At least 98% of participants agreed that the system was easy to use and they would be willing to use it throughout pulmonary rehabilitation. The system transmitted usable data from 98% (95% CI 96 to 100) of sessions and introduced minimal artefact. Mean absolute differences were 0.365 beats/minute for heart rate and 0.133% for oxyhaemoglobin saturation. For heart rate, exact agreement was 72% (SD 9) and similar agreement (within 3 beats/minute) was 99% (SD 1). For oxyhaemoglobin saturation, exact agreement was 87% (SD 3) and similar agreement (within 3%) was 100% (SD 0).The telemonitoring system used in this study was sufficiently valid and acceptable for use in at-home pulmonary rehabilitation by people with chronic respiratory disease.ClinicalTrials.gov NCT03295474 and NCT03004716 (subgroup study).
