Abstract
BACKGROUND: The Low-Back Outcome Scale (LBOS) of Greenough and Fraser and the Oswestry disability index (ODI) were compared to the patient satisfaction index (PSI) in lumbar disc herniation (LDH) surgery. METHODS: A total of 134 patients who underwent discectomy were followed through assessment of pre- and post-surgical satisfaction by the PSI, the LBOS, and the ODI. The LBOS were rated as satisfied if the outcomes were excellent or good and as dissatisfied if fair and poor. Considering the ODI, clinically satisfied was defined as a 13-point improvement from the baseline ODI scores. Phi (Φ) correlation analysis was used to study the correlation among the PSI, the LBOS and the ODI scores as proxy for patients' satisfaction. RESULTS: Mean age of patients was 48.9 years. Significant improvement from the pre- to post-operative ODI scores was observed. Post-surgical satisfaction based on the PSI, the ODI, and the LBOS were 70.9%, 76.8%, and 81.3%, respectively. Regarding patient satisfaction, there were weak associations between LBOS vs. PSI and ODI vs. PSI (Φ=-0.054, P=0.533) and (Φ=-0.129, P=0.136), respectively. CONCLUSIONS: Our study showed that the ODI and the LBOS were not reflective of patients' satisfaction after discectomy.
