Most patients recover very well but research consistently shows that 1 in 5 patients still have pain many months after surgery. Doctors often prescribe opioid medications for pain after surgery (e.g. Percocet, hydromorphone, codeine). These medications can be helpful for some people, but they can also be dangerous, particularly when used for a long time. Many patients don't like the way opioids make them feel and would prefer alternative pain management strategies. Some people become addicted to opioids, have a difficult time reducing the dose of opioids, or have lasting health problems after using them.\n\nPeople in this study will be randomized to either have usual care or a new pathway designed to improve pain control and decrease opioid use after knee replacements. This study will have an intervention coordinator who will assess patients before surgery and who will follow up with patients regularly after surgery to make sure their pain is controlled and to avoid long-term opioid use. This study will use education, physiotherapy, psychological therapy, ice/cold, and non-opioid pain medications. As pain medications may work differently in different patients, the coordinator will check on each patient to look for pain control and assist to reduce the amount of opioids used after surgery.\n\nThis study will help people have safer and more effective pain management after surgery which may lead to better recovery, higher satisfaction, and a lower risk of being harmed by opioids after surgery."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Adult (18+)\n* Undergoing elective total knee arthroplasty (TKA) for knee arthritis\n* Can use a simple electronic (phone or tablet) device\n* Provide informed consent to participate\n\nExclusion Criteria:\n\n* Revision surgery\n* Simultaneous bilateral arthroplasties\n* Unable to consent (e.g., cognitive disability or substantial language barrier without a support person)'}, 'identificationModule': {'nctId': 'NCT04968132', 'acronym': 'OREOS', 'briefTitle': 'Opioid Reduction in Orthopaedic Surgery (OREOS) - Knees', 'organization': {'class': 'OTHER', 'fullName': 'McMaster University'}, 'officialTitle': 'Opioid Reduction in Orthopaedic Surgery (OREOS): a Feasibility Randomized Controlled Trial in Knee Replacement Patients', 'orgStudyIdInfo': {'id': 'OREOS-knee'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'ACTIVE_COMPARATOR', 'label': 'Standard care group', 'description': 'This group will receive standard perioperative care, surgical treatment, and pain medications.', 'interventionNames': ['Other: Standard care']}, {'type': 'EXPERIMENTAL', 'label': 'Opioid reduction group', 'description': 'Patients will participate in a multicomponent pathway coordinated by a trained coordinator who will facilitate patient participation and engagement with each interventional component.', 'interventionNames': ['Other: Multicomponent opioid reduction and pain management pathway']}], 'interventions': [{'name': 'Multicomponent opioid reduction and pain management pathway', 'type': 'OTHER', 'description': 'Pre-operative pain education and expectation setting, identification and modification of risk factors in high risk patients, postoperative individualized analgesic prescriptions, and continued support for pan control and recovery facilitated by an interventions coordinator.', 'armGroupLabels': ['Opioid reduction group']}, {'name': 'Standard care', 'type': 'OTHER', 'description': 'Standard perioperative care, surgical treatment, and pain medications.', 'armGroupLabels': ['Standard care group']}]}, 'contactsLocationsModule': {'locations': [{'zip': 'L8N 4A6', 'city': 'Hamilton', 'state': 'Ontario', 'country': 'Canada', 'facility': "St. Joseph's Healthcare Hamilton", 'geoPoint': {'lat': 43.25011, 'lon': -79.84963}}], 'overallOfficials': [{'name': 'Harsha Shanthanna, MD PhD FRCPC', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'McMaster University'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'UNDECIDED'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Kim Madden', 'class': 'OTHER'}, 'collaborators': [{'name': "St. Joseph's Healthcare Hamilton", 'class': 'OTHER'}, {'name': 'McMaster Surgical Associates', 'class': 'OTHER'}, {'name': "St. Joseph's Healthcare Foundation", 'class': 'OTHER'}], 'responsibleParty': {'type': 'SPONSOR_INVESTIGATOR', 'investigatorTitle': 'Assistant Professor', 'investigatorFullName': 'Kim Madden', 'investigatorAffiliation': 'McMaster University'}}}}
