The number of remotely monitored patients grew by 44 percent to 7.1 million in 2016, according to the latest figures from Berg Insight. The market, according to the research firm, has entered a growth phase fuelled by rising market acceptance in several key verticals. Connected medical devices used for various forms of personal health tracking are not included in this figure.
Berg Insight estimates that the number of remotely monitored patients will grow at a compound annual growth rate (CAGR) of 47.9 percent to reach 50.2 million by 2021.
The two main applications are monitoring of patients with sleep therapy devices and monitoring of patients with implantable cardiac rhythm management (CRM) devices. These two verticals accounted for 80 percent of all connected home medical monitoring systems in 2016.
"The number of remotely monitored sleep therapy patients grew by 70 percent in 2016, mainly driven by Resmed that has made connected healthcare a cornerstone of its strategy," Anders Frick, Senior Analyst at Berg Insight, said in a statement.
Other leading vendors in this segment are Philips Respironics and SRETT.
The CRM market, on the other hand, is led by companies such as Medtronic, Boston Scientific and St. Jude Medical (now Abbott) that included connectivity in CRM solutions more than a decade ago.
Telehealth is the third largest segment with 0.50 million connections at the end of the year. Leading telehealth hub vendors include Tunstall Healthcare, Honeywell, Cardiocom, Philips and Qualcomm Life.
All other device categories — including ECG, glucose level, medication adherence and others — stood for less than one million connections together.
Berg has also found that cellular connectivity has already replaced PSTN and LAN as the de-facto standard communication technology for most types of connected home medical monitoring devices. The number of mHealth devices with integrated cellular connectivity increased from 3.0 million in 2015 to 4.9 million in 2016.
Finally, the use of BYOD connectivity will increase the most during the next five years, with a forecasted CAGR of 109 percent.
