Day Case Lumbar Fusion Surgery
This article examines the prognostic value of preoperative physical composite scores on postoperative outcomes in patients undergoing lateral lumbar interbody fusion (LLIF). The study divided patients into two cohorts based on their preoperative VR-12 Physical Composite Score (PCS): those with lesser physical function and those with greater physical function. Patient-reported outcome measures were collected before and after surgery. The results showed that patients with lesser physical function had significantly inferior preoperative scores in all domains, except for mental health and leg pain. At various postoperative time points, patients with lesser physical function reported inferior scores in physical function, mental health, and disability outcomes. However, the baseline VR-12 PCS scores did not limit the magnitude of postoperative improvement. This suggests that baseline scores may indicate inferior outcomes but do not affect the overall improvement after surgery

ABSTRACT
PURPOSE: To determine the prognostic value of preoperative Veterans RAND-12 (VR-12) Physical Composite Score (PCS) scores on postoperative clinical outcomes in patients undergoing lateral lumbar interbody fusion (LLIF).
METHODS: LLIF patients were separated into 2 cohorts based on preoperative VR-12 PCS scores: VR-12 PCS < 30 (lesser physical function) and VR-12 PCS ≥ 30 (greater physical function). Patient-reported outcome measures (PROMs) of VR-12 PCS, VR-12 Mental Composite Score (MCS), Short Form-12 (SF-12) PCS, SF-12 MCS, Patient-Reported Outcomes Measurement Information System Physical Function (PROMIS-PF), Patient Health Questionnaire-9 (PHQ-9), Visual Analog Scale (VAS) Back Pain (VAS-BP), VAS Leg Pain (VAS-LP), and Oswestry Disability Index (ODI) were collected at preoperative and up to 2-year postoperative time points. Mean postoperative follow-up time was 16.69 ± 8.53 months. Minimum clinically important difference (MCID) achievement was determined by comparing ∆PROM to previously established thresholds.
RESULTS: Seventy-eight patients were included, with 38 patients with lesser preoperative physical function scores. Patients with lesser physical function reported significantly inferior preoperative PROM scores in all domains, except for SF-12 MCS and VAS-LP. At the 6-week postoperative time point, patients with lesser physical function reported significantly inferior VR-12 PCS, VR-12 MCS, SF-12 PCS, PROMIS-PF, and PHQ-9. At the final postoperative time point, patients with lesser physical function reported significantly inferior VR-12 PCS, VR-12 MCS, PROMIS-PF, PHQ-9, and ODI. Magnitude of 6-week postoperative improvement was significantly higher in the lesser physical function cohort for VR-12 PCS.
: Patients undergoing LLIF with worse baseline VR-12 PCS scores reported inferior postoperative physical function, mental health, and disability outcomes. At the final postoperative follow-up, magnitude of postoperative improvement and MCID achievement did not significantly differ. Baseline VR-12 PCS scores may indicate inferior postoperative clinical outcomes in physical function, mental health, and disability in patients undergoing LLIF; however, baseline VR-12 PCS does not limit the magnitude of postoperative improvement.
