Rapid identification of physiological derangement and timely action are related to improved outcome.1 In high-income countries, this is achieved using sophisticated continuous monitoring systems facilitated by high nurse to patient ratios. In low-income and middle-income countries (LMIC), lack of staff and equipment means this is difficult to achieve.2 3 An alternative solution for resource-limited settings, enabled by recent advances in sensor technologies, is the use of low-cost wearable devices.4 Some of these devices have the additional advantage of being able to record continuous data, which allow more complex analysis and may facilitate even better risk prediction.5–7 There is, however, limited use of these devices in the unique and challenging environments of LMIC intensive care units (ICUs).3 The majority of validatory data concerning wearables come from community settings in relatively healthy ambulatory individuals.8–10 In hospital environments, the accuracy of data derived from unstable or critically ill patients is less certain.10 Studies indicate a … ER -
