Postal Delivery of Sleep Monitoring Devices: Research Implications

The purpose of this article is to describe the protocol development, feasibility, and lessons learned in the postal mail delivery of sleep monitoring devices to study participants. The original study protocol included four in-person visits with distribution of a sleep monitoring device (Actiwatch) and return of the Actiwatch via the postal service in a self-addressed, stamped envelope. The COVID-19 pandemic limited in-person research contact thus requiring a remote study protocol for application and return of the Actiwatches using postal delivery. While there were postal delivery and return challenges, the overall return rate of 94.4% confirmed remote protocol feasibility. Key lessons learned were: consistent and frequent communication via telephone calls and/or text; confirming required postage; and use of package tracking labels. All these strategies contributed to successful postal delivery/return and concomitantly decreased the potential loss of data and valuable research equipment.
