    Abstract

    Introduction: Over 160,000 people with severe hip or knee pain caused by osteoarthritis undergo total hip (THR) or knee replacement (TKR) surgery each year in the UK within the National Health Service (NHS) and this number is expected to increase. Innovative approaches to evaluating surgical outcomes will be needed to respond to the increasing burden of joint replacement surgery. The Sensor Platform for Healthcare in a Residential Environment, Interdisciplinary Research Collaboration (SPHERE-IRC) have developed a system of sensors that can monitor the health-related behaviours of people living at home. The system includes sensors for the home environment (measuring temperature, humidity, room occupancy, water and electricity usage) a wrist-band body-worn activity monitor and silhouette (body outline) sensors. The aim of HEmiSPHERE (Hip and KnEe Study of a Sensor Platform of HEalthcare in a Residential Environment) is to a) determine, the accuracy and feasibility of the sensory data as it compares to conventional assessment of health outcomes after surgery using patient self-reported questionnaires, and (b) to explore how the SPHERE system is useful for every day clinical decision making.

    Methods and Analysis: A feasibility study recruiting and installing the SPHERE system in the homes of up to 30 NHS adult patients as they undergo a THR or TKR. Through a mixed methods design the SPHERE system will monitor and record continuous measurements of daily behaviour. Main outcomes will assess the relationships between environmental, behavioural and movement data and the parameters of interest from the standard clinical assessments measuring patient outcomes over time. Patient interviews and focus groups with consultant orthopaedic surgeons will provide depth in understanding of the acceptability, feasibility and accuracy of the data.

    Ethics and Dissemination: Ethical approval has been obtained through South West – Central Bristol Research Ethics Committee (17/SW/0121). We aim to disseminate the findings through regional talks and seminars, international conferences and peer-reviewed journals and social medi
