Detection of Physiological Deterioration by the SNAP40 Wearable Device Compared to Standard Monitoring Devices in the Emergency Department
Detection of Physiological Deterioration by the SNAP40 Wearable Device Compared to Standard Monitoring Devices in the Emergency Department
In recent years there has been increasing focus on the earlier detection of deterioration in the clinical condition of hospital patients with the aim of instigating earlier treatment to reverse this deterioration and prevent adverse outcomes. This is especially important in the ED, a dynamic environment with large volumes of undifferentiated patients, which carries inherent patient risk. SNAP40 is an innovative medical-grade device that can be worn on the upper arm that continuously monitors patients' vital signs including relative changes in systolic blood pressure, respiratory rate, heart rate, movement, blood oxygen saturation and temperature. It uses automated risk analysis to potentially allow clinical staff to easily and quickly identify high-risk patients. The aim of this study is to investigate whether the SNAP40 device is able to identify deterioration in the vital sign physiology of an ED patient earlier than current standard monitoring and observation charting techniques.
As well as the potential of the SNAP40 device to improve patient safety, we believe that the SNAP40 device will increase ED efficiency, improve and increase use of resources and enable improved patient flow through the ED. Currently the only option for continuous monitoring or regular observations in the ED is to connect the patient to a standard monitor. Whilst these monitors can be portable they are not lightweight enough to allow the patient to be ambulatory within the ED and therefore require the patient to have a bed and a bed space or cubicle. This leads to lack of space within the ED, less cubicles (which allow privacy) free for performing history taking, examination and procedures, difficulty accessing patients and difficulty transporting them to areas where specialist tests can be performed (i.e. radiology and ECG). SNAP40 may remove the need for patients to be confined to beds and bed spaces (unless clinically required) freeing up space within the ED and allowing the ED care processes to occur much more freely increasing efficiency and speed of patient processing. This will undoubtedly lead to improved patient experiences around their ED and hospital journey.
The SNAP40 device also has the potential to free up resources, which can be used to improve patient care and experience in the ED. SNAP40 may reduce clinical staff time taken to record observations enabling them to provide patients with other aspects of care (i.e. analgesia and treatments) more regularly and in a timelier manner. Clinical staff may be able to spend more time with patients allowing better quality communication with them and their relatives. There will potentially be more time for traditional nursing care and personal care.
Whilst there are some other similar medical devices on the market (i.e. www.biovotion.com, www.sensium-healthcare.com, www.vitalconnect.com, http://www.caretakermedical.net) using wristbands, patches or finger cuff technology, currently none are being used in ED clinical practice.
This study will examine the SNAP40 device by comparing its performance to detect physiological deterioration against standard observations taken by clinical staff (nurses, doctors and clinical support workers) within the ED. The study will assess whether the device is able to detect physiological derangement sooner that standard monitoring devices.
