Abstract
Background: Few studies have looked at the role of telemodems in monitoring patients on Non-Invasive Ventilation (NIV). Telemodems stream daily ventilation data to a secure, remote site. Data can be assessed, informing decisions around course of therapy. This may impact quality of life, as we can decide if clinic attendance is required. Our hospital is one of the only in the UK regularly using telemodems.
Aim: To assess if NIV use at set-up and over 3 months is similar/better when telemodems are used compared to standard SD (memory) cards, and if their use can reduce number of clinic visits.
Method: Patients set-up on domiciliary NIV (2013-2014) were recruited and randomly assigned to telemodems or SD card. We prospectively downloaded data over 3 months. Those with no/missing data were excluded. We recorded av. daily usage (min) and clinic visits.
Results: 15 telemodem and 20 SD patients were included. Av. use over 90 days was 306.7 (Modem) vs. 314.1min (SD) (P=0.66). Av. Use at 1 month was 350 (Modem) vs 303.6 min (SD) (P=0.24). The SD group had significant increase in use at month 3 (p=0.04). The modem group increased use over 3 months but not significantly (p=0.07). Av. number of clinic visits was 4.43 (Modem) vs 3.43 (SD).
Conclusion: After 1 month NIV adherence was greater in the telemedicine arm suggesting quicker set-up. Whilst use at 3 months is similar, the technology allowed instant data access reducing unnecessary visits. It helped identify those who needed more intensive initial support. Higher clinic visits in the modem group supports this. A larger prospective study reviewing adherence and safety is required.
