Preoperative Mental Health is not Predictive of Patient-reported Outcomes Following a Minimally Invasive Lumbar Discectomy

Study Design:
This is a retrospective cohort study.
Objective:
To determine if preoperative mental health is associated with patient-reported outcomes (PROs) following a minimally invasive lumbar discectomy.
Summary of Background Data:
PROs are commonly used to quantify a patient’s perceived health status. Recently, mental health has been theorized to directly affect patients’ perception of their disability and pain after spine surgery.
Materials and Methods:
A registry of patients who underwent a primary, single-level minimally invasive lumbar discectomy was reviewed. The association between preoperative Short-Form Health Survey mental composite score (MCS) and change in PROs [Oswestry Disability Index, back and leg visual analog scale (VAS) pain scores] from preoperative to postoperative (6-week, 12-week, 6-month) timepoints was assessed using multivariate regression controlling for patient demographics and the respective preoperative PRO. Patients in the top and bottom quartiles of preoperative MCS were compared regarding achievement of minimum clinically important difference for each PRO.
Results:
A total of 110 patients were included in the analysis. Better preoperative mental health was associated with lower preoperative disability and decreased preoperative back VAS (P
