Abstract

Background

Patients’ expectations influence their decisions to undergo surgery for scoliosis, and fulfillment of expectations is an important patient-centered outcome.

Questions/Purposes

In a 2-year cohort study, we compared the proportion of expectations fulfilled based on the number of vertebrae involved in surgery between adult lumbar scoliosis patients and controls with other degenerative conditions.

Methods

Patients pre-operatively completed a valid lumbar surgery expectations survey addressing expected improvements for symptoms, function, and psychosocial well-being (scores from 0 to 100; higher score indicates more expectations). Two years post-operatively, the patients completed another survey, this one recording how much improvement they actually experienced; fulfillment was defined as a proportion (i.e., received improvement/expected improvement). The range was 0 (none fulfilled) to > 1 (expectations surpassed). We further analyzed data according to the number of vertebrae involved in the surgery.

Results:

We included 42 scoliosis patients and 134 controls with similar mean ages (66 vs 64 years, respectively) and pre-operative expectations survey scores (72 vs 70, respectively). When we stratified by < 3 or ≥ 3 vertebrae, we found that the proportion of expectations fulfilled differed for scoliosis patients but not for controls. In multivariable analysis, lower proportion of expectations fulfilled was associated with greater pre-operative expectations, less improvement in pre- to post-operative disability, and the composite interaction of scoliosis and number of vertebrae.

Conclusions

Compared with controls, scoliosis patients who required surgery to a greater number of vertebrae were more likely to have unfulfilled expectations 2 years post-operatively. Our findings support the importance of addressing expectations pre-operatively with all patients, especially those with scoliosis who require surgery to ≥ 3 vertebrae.
