Background context:
Positive psychosocial factors early after surgery, such as resilience and self-efficacy, may be important characteristics for informing individualized postoperative care.
Purpose:
To examine the association of early postoperative resilience and self-efficacy on 12-month physical function, pain interference, social participation, disability, pain intensity, and physical activity after lumbar spine surgery.
Study design/setting:
Pooled secondary analysis of prospectively-collected trial data from two academic medical centers.
Patient sample:
248 patients who underwent laminectomy with or without fusion for a degenerative lumbar condition.
Outcome measures:
Physical function, pain inference, and social participation (ability to participate in social roles and activities) were measured using the Patient Reported Outcomes Measurement Information System. The Oswestry Disability Index, Numeric Rating Scale, and accelerometer activity counts were used to measure disability, pain intensity, and physical activity, respectively.
Methods:
Participants completed validated outcome questionnaires at 6 weeks (baseline) and 12 months after surgery. Baseline positive psychosocial factors included resilience (Brief Resilience Scale) and self-efficacy (Pain Self-Efficacy Questionnaire). Multivariable linear regression analyses were used to assess the associations between early postoperative psychosocial factors and 12-month outcomes adjusting for age, sex, study site, randomized group, fusion status, fear of movement (Tampa Scale of Kinesiophobia), and outcome score at baseline. This study was funded by Patient-Centered Outcomes Research Institute and Foundation for Physical Therapy Research. There are no conflicts of interest.
Results:
Resilience at 6 weeks after surgery was associated with 12-month physical function (unstandardized beta = 1.85 [95% CI: 0.29; 3.40]), pain interference (unstandardized beta = -1.80 [95% CI: -3.48; -0.12]), social participation (unstandardized beta = 2.69 [95% CI: 0.97; 4.41]), and disability (unstandardized beta = -3.03 [95% CI: -6.04; -0.02]). Self-efficacy was associated with 12-month disability (unstandardized beta = -0.21 [95% CI: -0.37; -0.04].
Conclusions:
Postoperative resilience and pain self-efficacy were associated with improved 12-month patient-reported outcomes after spine surgery. Future work should consider how early postoperative screening for positive psychosocial characteristics can enhance risk stratification and targeted rehabilitation management in patients undergoing spine surgery.
