Study population: Adult patients recovering from major intra-cavity abdominal surgery being discharged from the Mater Misericordiae University Hospital in Dublin, Ireland.

Brief summary: Unrecognised changes in patients' vital signs after surgery can result in preventable complications. Current standard practice includes routine monitoring of patient vital signs up until hospital discharge.

Upon discharge from hospital, all forms of routine vital sign monitoring ceases. The availability and use of wearable technology in healthcare is increasing rapidly. The role of wearable technology in the remote monitoring of patients at high-risk of post-operative complications and hospital readmission after discharge from hospital is unclear.

This pilot study is aimed to assess the feasibility of using wearable technology in patients recovering from major intracavity surgery after hospital discharge in the Irish healthcare setting.

Detailed description: Patients undergoing major abdominal and pelvic surgery can have re-admission rates of over 20% in the first 90-days after surgery.

In Ireland the 30-day mortality following emergency abdominal surgery is 6.6%, and 90-day mortality 11.6% (1). Furthermore, 20% of post-operative deaths occur after hospital discharge in those over 80 years of age, of which over 95% occurs during the first six-weeks (2).

Despite this high risk, many patients are discharged home from hospital when medically fit and continuous monitoring discontinues. In hospital, patient monitoring is routine to identify patient deterioration at an early stage using the national early warning score (NEWS), which consists of the following clinical observations: heart rate, blood pressure, temperature, respiratory rate, oxygen saturation and level of consciousness. This monitoring is done routinely in the hospital ward at least every four hours. This monitoring stops when patients are discharged from hospital. Patients discharged are given general advice for recovery and, as part of current practice, are advised to contact their General Practitioner (GP) or emergency department if feeling unwell. Despite this, mortality in the post-discharge period accounts for nearly a quarter of all post-operative deaths.

Home monitoring of patients with chronic conditions has previously been shown to be of some utility. Recently, during the COVID-19 pandemic, remote home monitoring of patients diagnosed with COVID-19 who did not meet hospital admission criteria were managed by smartphone application and peripheral pulse oximetry.

To date, no previously published studies have adopted home monitoring for a patient group that is at a high risk of re-admission. In addition, simple questionnaires used to monitor postoperative recovery (such as the QoR-15) exist, that are reflective of a patient's current health status, but they have not been used to monitor patients after hospital discharge.

In this study, the investigators aim to test the feasibility and patient compliance of remote wearable biosensor technology monitoring after major intracavity surgery. The remote monitoring combines vital sign observations (ECG, heart rate, temperature and respiratory rate) and a health status assessment questionnaire.

The study protocol has been approved by the Mater Misericordiae University Hospital Institutional Review Board (IRB) (Reference: 1/378/2207). Any protocol modifications will be submitted for the IRB review and approval.
