For patients admitted to the medical ward, it is usually difficult to predict if their clinical condition will deteriorate, however subtle changes in vital signs are usually present 8 to 24 hours before a life-threatening event such as respiratory failure leading to ICU admission, or unanticipated cardiac arrest. Such adverse trends in clinical observations can be missed, misinterpreted or not appreciated as urgent. New continuous and wearable 24/7 clinical vital parameter monitoring systems offer a unique possibility to identify clinical deterioration before patients progress beyond the point-of-no-return, where adverse events are inevitable. The WARD-COPD project aims to determine the number and duration of cardiopulmonary micro events during the first 4 days after hospital admission with Acute Exacerbation of COPD. We will also test the server installation, develop a database of core data and assess the frequency of artefacts and failure to capture the continuous monitoring signal.
