Internet-based home asthma telemonitoring: can patients handle the technology?

Area of Science:

• Pulmonary Medicine
• Health Informatics
• Patient Monitoring

Background:

• Asthma management requires regular monitoring of lung function.
• Home-based telemonitoring offers a potential solution for continuous patient oversight.
• Evaluating the efficacy and patient acceptance of new technologies is crucial for adoption.

Purpose of the Study:

• To assess the validity of self-performed spirometry testing within a home telemonitoring system for asthma patients.
• To determine patient acceptance and usability of an internet-based asthma telemonitoring system.

Main Methods:

• An internet-based telemonitoring system was used to collect home spirometry data and symptom reports.
• Patients underwent a brief training session before performing twice-daily spirometry tests for three weeks.
• A medical professional conducted a supervised spirometry test at the end of the monitoring period to compare with self-tested results.

Main Results:

• No significant difference was found between unsupervised home spirometry self-testing and physician-supervised testing.
• Spirometric index variability in self-testing was comparable to previously reported within-subject variability.
• Despite limited computer experience, most patients found the system easy to use and expressed high interest in future use.

Conclusions:

• Spirometry self-testing during home telemonitoring is a valid method for asthma management.
• Internet-based home asthma telemonitoring systems are feasible and well-accepted, even by patients with no prior computer experience.
