TI  - Defining a Minimum Clinically Important Difference in Patient-Reported Outcome 
      Measures in Lumbar Tubular Microdecompression Patients.
PG  - 538-543

AB  - BACKGROUND: Patient-reported outcome measures (PROMs) are critical tools used in 
      the assessment and reporting of surgical outcomes. However, significant 
      differences in PROM scores have not been shown to consistently correlate with 
      clinical improvement from the physician or patient perspective. Defining a 
      minimum clinically important difference (MCID) for PROMs offers interpretation of 
      surgical outcomes with an emphasis on patient-centered feedback. The goal of this 
      study was to define a MCID for the following PROMs in lumbar tubular 
      microdecompression (LTMD) patients: the EuroQol-Five Dimensions (EQ-5D) index, 
      Oswestry Disability Index (ODI), leg pain visual analog scale (VAS), and low back 
      pain VAS. METHODS: This study examined 235 index LTMD patients with PROMs 
      collected at preoperative evaluation and 1-year follow-up. Using an anchor-based 
      approach with patient satisfaction index, a receiver operating characteristic 
      analysis was performed to define a MCID in the EQ-5D index, ODI, leg pain VAS, 
      and low back pain VAS. RESULTS: The patients had a mean age of 65.18 +/- 12.81 
      years, and 47.7% were male. The MCID values for the EQ-5D, ODI, leg pain VAS, and 
      low back pain VAS are 0.219, 15.0-16.5, 0.5, and 2.5-3.5, respectively. 
      CONCLUSIONS: This study helps define a MCID for the EQ-5D index in LTMD patients. 
      Given its ease of administration and economic relevance, further characterization 
      of the EQ-5D index may warrant its use as a potential alternative or adjunct to 
      the routinely collected PROMs following spine surgery. LEVEL OF EVIDENCE: 3.
