We aimed to compare continuous temperature-monitoring using Bluetooth-enabled thermometer (BET) and intermittent monitoring by digital thermometer (DT) in neonates. Continuous monitoring using BET identified 377 episodes of hypo/hyperthermias in 90 baby-days; 316 (83.8%) episodes were confirmed by DT and 61 (16.2%) were false alarms. Five episodes were missed by BET. The agreement between digital thermometer and BET was good. Continuous temperature monitoring helps in early identification of hypo/hyperthermia in neonates.
