People undertaking pulmonary rehabilitation are willing and able to provide accurate data via a remote pulse oximetry system: a multicentre observational study.
Journal of Physiotherapy 2018 December 18
QUESTIONS: 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?
DESIGN: Multicentre, prospective, observational study.
PARTICIPANTS: One hundred and five adults with chronic respiratory disease who were referred to pulmonary rehabilitation.
INTERVENTION: 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: 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.
RESULTS: 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).
CONCLUSION: 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.
