Preoperative expectations of patients with degenerative cervical myelopathy: an observational study from the Canadian Spine Outcomes and Research Network

•Most patients expected improvement in functional status and myelopathic symptoms.•The foremost desired outcome by patients was halting neurological deterioration.•Expectations predictors: comorbidities, pain, symptoms duration, no failure of other treatment. Despite an abundance of literature on degenerative cervical myelopathy (DCM), little is known about preoperative expectations of these patients. The primary objective was to describe patient preoperative expectations. Secondary objectives included identifying patient characteristics associated with high preoperative expectations and to determine if expectations varied depending on myelopathy severity. This was a retrospective study of a prospective multicenter, observational cohort of patients with DCM. Patients who consented to undergo surgical treatment between January 2019 and September 2022 were included. An 11-domain expectation questionnaire was completed preoperatively whereby patients quantified the expected change in each domain. The most important expected change was captured. A standardized expectation score was calculated as the sum of each expectation divided by the maximal possible score. The high expectation group was defined by patients who had an expectation score above the 75th percentile. Predictors of patients with high expectations were determined using multivariable logistic regression models. There were 262 patients included. The most important patient expectation was preventing neurological worsening (40.8%) followed by improving balance when standing or walking (14.5%), improving independence in everyday activities (10.3%), and relieving arm tingling, burning and numbness (10%). Patients with mild myelopathy were more likely to select no worsening as the most important expected change compared to patients with severe myelopathy (p
