Veterans RAND 12-item physical component score seen as valid measure in spinal fusion

Results showed the Veterans RAND 12-item physical component score offers a valid and universally applicable physical outcome assessment of patients undergoing minimally invasive transforaminal lumbar interbody fusion.
Michael T. Nolte, MD, and colleagues from the department of orthopedic surgery at Rush University Medical Center retrospectively analyzed data on 59 patients (mean age of 53.8 years) who underwent single-level minimally invasive (MIS) transforaminal lumbar interbody fusion (TLIF) for degenerative spinal pathology from March 2015 to June 2019. According to the study, patients were excluded if they had surgery for metastatic, traumatic or infectious etiologies or incomplete survey results.
Among the patients, the researchers compared several patient-reported outcome measures (PROMs) from preoperative baseline to 1 year. PROMs included the Veterans RAND 12-item physical component score (VR-12 PCS), SF-12 PCS and Patient-Reported Outcomes Measurement Information System physical function (PROMIS-PF) score.
Nolte and colleagues found patients demonstrated “significant improvements” in all three surveys at 6 months and 1 year postoperatively. They noted strong correlations between the VR-12 PCS, the SF-12 PCS and the PROMIS-PF at all timepoints.
“VR-12 PCS was strongly correlated with the historically validated SF-12 PCS system, as well as with the more recent PROMIS-PF survey,” Nolte and colleagues wrote in the study. “For patients undergoing MIS TLIF surgery, the VR-12 PCS offers a fast, easy to complete, nonproprietary, and universally applicable physical outcome assessment,” they concluded.
