Purpose
The purpose of this study was to determine the accuracy of self-reported non-smoking status in subjects undergoing elective orthopedic surgery as confirmed by serum cotinine levels.
Methods
Institutional Review Board approval was obtained for this retrospective review of consecutive subjects that underwent elective orthopedic surgery by a single fellowship-trained orthopedic surgeon. All patients provided smoking history (active, former, or non-smoker). Serum cotinine levels defined each subject as “non-smoker”, “passive tobacco exposure”, or “active smoker”. Self-reported non-smokers were eligible for inclusion. Subjects were excluded if they failed to provide smoking history, reported themselves as “smokers”, and/or had unavailable serum cotinine levels. Self-reported non-smoking status accuracy was determined by dividing the total number of included subjects by the number of subjects that were defined as “non-smoker” or “passive tobacco exposure” on their serum cotinine test.
Results
A total of 378 patients (mean age of 42.5 (13-78) years and 68% female) self-reported as non-smokers and were included. A total of 369 subjects had serum cotinine levels consistent with “non-smoking” resulting in a self-reported non-smoking status accuracy of 97.6%. None of the former smokers had cotinine levels consistent with active smoker status.
Conclusion
Subjects undergoing elective orthopedic surgery self-report as non-smokers with an accuracy of 97.6%. This suggests that routine serum cotinine testing of non-smokers in this patient population may not be necessary.
The 2022 International Society of Hip Preservation (ISHA) physiotherapy agreement on assessment and treatment of greater trochanteric pain syndrome (GTPS) was intended to present a physiotherapy consensus on the assessment and surgical and non-surgical physiotherapy management of patients with GTPS. The panel consisted of 15 physiotherapists and eight orthopaedic surgeons. Currently, there is a lack of high-quality literature supporting non-operative and operative physiotherapy management. Therefore, a group of physiotherapists who specialize in the treatment of non-arthritic hip pathology created this consensus statement regarding physiotherapy management of GTPS. The consensus was conducted using a modified Delphi technique to guide physiotherapy-related decisions according to the current knowledge and expertise regarding the following: (i) evaluation of GTPS, (ii) non-surgical physiotherapy management, (iii) use of corticosteroids and orthobiologics and (iv) surgical indications and post-operative physiotherapy management.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
