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 wristband 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 (1) determine the
accuracy and feasibility of the sensory data as it
compares with conventional assessment of health
outcomes after surgery using patient self-reported
questionnaires, and (2) to explore how the SPHERE
system is useful for everyday 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 in-depth understanding of the
acceptability, feasibility and accuracy of the data.
Ethics and dissemination We aim to disseminate the
findings through regional talks and seminars, international
conferences and peer-reviewed journals and social media.
