Application of Wearable Technology in High-risk Surgical Patients in the Perioperative Period
Study Details
Study Description
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 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 oximetery.
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.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Adult patients being discharged from hospital following intra-abdominal or pelvic surgery Patient compliance with wearable biosensor monitoring after major intracavity surgery. The remote monitoring is made up of a wearable biosensor and a data-enabled relay device which will detect vital sign observations (ECG, heart rate, temperature and respiratory rate) and a health status assessment questionnaire. |

Outcome Measures
Primary Outcome Measures
- Primary Objective [30-days]
Assess compliance with remote monitoring in the first 30-days after hospital discharge following intra-abdominal or pelvic surgery. Compliance will be defined as wearing the biosensor for at least 20 hours per day.
Secondary Outcome Measures
- Secondary Outcome [30-days]
Retrospectively explore how recorded vital signs relate to any unplanned hospital admission or GP visits in the first 30-days after hospital discharge. The 30-day questionnaire performed will be the Quality of Recovery 15 (QoR-15) score
