Patient FAQs
What is the purpose of the TRIAD Study?
The TRIAD study is investigating whether using a dilute povidone-iodine (betadine) wash during hip or knee replacement surgery can reduce the risk of surgical site infections (SSI) within 90 days after surgery. The study will use data from the AOANJRR registry to compare outcomes between betadine wash and standard saline wash.
What does participation involve?
Your hospital will be randomly assigned to use either betadine or normal saline wash during surgery. Both are standard of care, and you will receive either regardless of participating in the study.
You will complete short questionnaires about your health, joint function, pain, and satisfaction before surgery, and at 90 days, 6, and 12 months after surgery.
The questionnaires take approximately 10 minutes and can be completed online or by phone.
Participation is voluntary, and you may withdraw at any time without affecting your care.
Are there any risks?
There is no added surgical risk beyond standard care.
The main risk is the time and minor inconvenience of completing questionnaires.
Your personal information is handled securely, minimising any risk of data leakage.
How is my data protected?
Personal information (e.g., name, date of birth, contact details, and surgery details) is stored in a secure database on the AOA RAPID Platform on the AOA RAPID platform.
Only you and your surgeon can access your individual results.
Data may be used in research publications, but your identity will never be disclosed.
You may nominate a family member or friend to help complete the questionnaires if preferred.
Is participation voluntary?
Participation is entirely voluntary and will not in any way affect your operation.
You can withdraw at any time without giving a reason, and your medical care will not be affected.
Any data already provided may still be used unless you request it be removed.
