The Incidence and Incubation Period of False Positive Cultures in Shoulder Surgery

100 participantsStarted 2015-05

Plain-language summary

This study will describe the time point at which a positive culture from a patient who has undergone shoulder surgery should be treated as an infection versus a false positive result that should be disregarded. Intraoperative biopsies will be taken and cultured from 50 subjects who have undergone an "open" surgical procedure and 50 from subjects undergoing an arthroscopic procedure.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * Patients undergoing primary open and arthroscopic shoulder surgery in which there is a clear diagnosis of a mechanical problem that is felt to be amenable to surgical intervention and there is no suspicion of infection. Examples include, but are not limited to: rotator cuff tear, labral tear, instability, impingement, and osteoarthritis. Exclusion Criteria: * Prior shoulder surgery * Prior glenohumeral injection within the last 6 months * Systemic or shoulder inflammatory disorder * Any clinical, imaging, or laboratory findings that raise suspicion of infection * Minors * Erythrocyte sedimentation rate (ESR) \>15 mm/hr for males less than 50 years old, \>20 mm/hr for males greater than 50 years old and females less than 50 years old, and \>30 mm/hr for females greater than 50 years old * C reactive protein (CRP) \>1 mg/d, * Procalcitonin (PCT) \>0.05 ng/ml.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
