Objective: A common expectation for patients after elective spine surgery is that the procedure will result in pain reduction and minimize the need for pain medication. Most studies report changes in pain and function after spine surgery, but few report the extent of opioid use after surgery. This systematic review aims to identify the rates of opioid use after lumbar spine fusion.Materials and Methods: PubMed, CINAHL, Cochrane Central Register of Controlled Trials, and Ovid Medline were searched to identify studies published between January 1, 2005 and June 30, 2020 that assessed the effectiveness of lumbar fusion for the management of low back pain.Results: Of 6872 abstracts initially identified, 329 studies met the final inclusion criteria, and only 32 (9.7%) reported any postoperative opioid use. Long-term opioid use after surgery persists for more than 1 in 3 patients with usage ranging from 6 to 85.9% and a pooled mean of 35.0% based on data from 21 studies (6.4% of all lumbar fusion studies).Discussion: Overall, opioid use is not reported in the majority of lumbar fusion trials. Patients may expect a reduced need for opioidbased pain management after surgery, but the limited data available suggests long-term use is common. Lack of consistent reporting of these outcomes limits definitive conclusions regarding the efficacy of spinal fusion for reducing long-term opioid. Patient decisions about undergoing surgery may be altered if they had realistic expectations about rates of postsurgical opioid use. Spine surgery trials should track opioid utilization out to a minimum of 6 months after surgery as a core outcome.

Introduction/Objectives Therapeutic alliance (TA) is an integral part of building a patient and clinician relationship. TA begins at the initial encounter; however, the specific TA behavioural practices that are most impactful and linked to pain reduction and improved function remain unclear. The primary objective of this study was to explore physical therapist behaviours and interactions during the initial physical therapy evaluation and how they related to the patient's perception of TA. A secondary objective was to explore the relationship between TA, pain intensity, and function. Methods A mixed methods study was conducted. Pain intensity, TA and self‐reported function were assessed at three time points. Spearman's Rho (ρ) was used to quantify if there was an association between increased TA and function and reduced pain intensity, while a checklist of TA themes and behavioural practices was used for the qualitative analysis. Results There was a statistically significant negative correlation between patient‐perceived TA and pain intensity immediately after the initial evaluation (ρ = −0.39 [p = 0.048]). Behavioural practices associated with higher TA included information gathering, pausing to listen, using humour and transitions, and use of clarifying questions. Behavioural practices associated with patient‐perceived lower TA interactions were lack of touch, the absence of pain neuroscience education, and not restating what the patient said during the interview. Conclusion This study highlights a relationship between TA and reduction of pain intensity after the initial evaluation and identifies key behavioural practices that could positively and negatively impact TA during the clinical encounter.
