The use of wearable devices in preventing hospital readmission and in improving the quality of life of chronic patients in the homecare Setting: A Narrative Literature Review.

Introduction: According to the World Health Organisation chronic diseases are the leading cause of mortality in the world, representing 60% of all deaths. Strategies employed to tackle chronic diseases aim to act on risk factors through adopting a healthy lifestyle. These strategies can be greatly implemented from the adoption of wearable devices, which allow a thorough and mini- mally invasive monitoring of patients' clinical data. This article aims to clarify whether wearable devices can help in preventing hospital readmission and improve quality of life in chronic patients.

Method: A literature search of electronic databases was performed in January 2017. The following databases were searched: The Cochrane Database of Systematic Reviews, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), Pub Med, EMBASE and MEDLINE.

Results: 33 articles met the inclusion criteria and were included in the literature review.

Discussion: Various wearable devices are currently available to monitor and keep records of diffe- rent clinical information. Some of them are proved to prevent hospital re-admissions and to treat effectively life-threatening situations in certain categories of chronic patients. Higher level of acceptability and usability are achieved when users are involved in the testing stage prior to the release of the device and/or the features and terms of use are clearly described to patients and carers. Wearable devices are also proved to be more accurate than clinical assessment only in estimating the risk of falls in chronic patients, thus improving safety in the home care setting. Regardless of their features, wearable devices are yet to be used by both healthcare professionals and patients on a large scale.
