About this study

Official title: Intervention to Reduce Sedentary Time in Older Adults Undergoing Orthopaedic Surgery: a Feasibility Study (INTEREST)

The aim of this study is to investigate the feasibility of an intervention to reduce sedentary behaviour in older adults waiting for hip and knee replacements. The study will be a randomised controlled trial design, including 2:1 randomisation into an intervention and usual care group respectively. A target of n=45 patients ≥60 years will be recruited from Russells Hall Hospital, Dudley, UK, approximately 8-10 weeks before surgery, assisted by research nurses. The variable-length intervention, informed by Self-Determination Theory (SDT), will be composed of multiple behaviour change techniques, namely motivational interviewing, individualised feedback on sedentariness, goal-setting, environmental modification, self-monitoring, and social support. Assessments will occur at baseline, 1 week pre-surgery, and 6 weeks post-surgery. The primary outcome will be the feasibility of the trial, assessed quantitatively using study statistics, and with mixed-methods assessment of acceptability, practicality, adaption, satisfaction, and safety via questionnaires given to participants. Exploratory outcomes will include physical function, cardiometabolic biomarkers, measurement of SDT constructs, and both objective and subjective measurement daily activity and sedentariness. The study will last up to 18 weeks per participant.

Read the detailed description

The aim of this study is to investigate the feasibility of an intervention to reduce sedentary behaviour in n=45 older adults undergoing orthopaedic surgery, at Russells Hall Hospital, Dudley, Birmingham, UK. Recruitment will be via screening of surgery lists followed by direct contact with potentially eligible participants. The intervention is designed utilising Self Determination Theory. It is designed to have multiple components: incorporating individualised feedback on sitting time, education about sedentary behaviour, individualised goal-setting and environmental modification according to each participant's own behavioural patterns and capabilities, motivational interviewing, and biweekly phone calls.

Due to variation in surgery times, the intervention will be variable but can last up to 18 weeks. Each participant will undertake 3-5 visits depending on whether they are in the control group (n=3 visits) or intervention group (n=5 visits). The intervention group will undergo baseline assessments, two intervention meetings, pre-surgical assessments, and a 6-week post-surgical follow up. These visits will occur in different weeks for each participant due to the variability of surgery, however visit 2 will occur 1 week after visit 1. Visit 3 will occur shortly thereafter but may also be combined with visit 2. Visit 4 will occur the week prior to surgery, which is intended to be 6-10 weeks after baseline. Visit 5 occurs 6 weeks post-surgery, which should be 12-18 weeks post-baseline. The primary outcome measure will be feasibility, assessed quantitatively with study statistics. Secondary outcome will be mixed-methods assessment of feasibility via bespoke participant questionnaires. Exploratory outcomes will cover a number of mental and physical health variables, including blood measures to assess cardiometabolic biomarkers, as well as physical function using the short physical performance battery (SPPB). Surgical recovery will be assessed using the Oxford Hip/Knee score and the SPPB. The results of this feasibility study will serve to aid the design of a definitive trial of an intervention to reduce sedentary behaviour in this population.

Questions about this trial

What is this clinical trial studying?

A study testing Sedentary behaviour reduction using motivational interviewing, education, individualised feedback, goal-setting, self-monitoring, environmental modification, and supportive phone calls in people with Orthopedic Disorder and Arthropathy of Knee, run by University of Birmingham at 1 site in United Kingdom.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 5 Jul 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Study uptake rates (as % of those approached who are randomised, recruitment rates (N/mth) (time frame: Assessed post-study-endpoint (up to month 18)). The study lists 10 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03740412, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Jul 2019.
