Preoperative disability influences effectiveness of MCID and PASS in predicting patient improvement following lumbar spine surgery
P Shahi, T Subramanian, O Maayan… - Clinical Spine …, 2023 - journals.lww.com
Study Design: Retrospective cohort. Summary of Background Data: Although minimal
clinically important difference (MCID) and patient acceptable symptom state (PASS) are
utilized to interpret Oswestry Disability Index (ODI), it is unclear whether there is a clearly
better metric between the two and if not, which metric should be utilized when. Objective: To
compare the characteristics of MCID and PASS when interpreting ODI after lumbar spine
surgery. Methods: Patients who underwent primary minimally invasive transforaminal lumbar …

147. Preoperative disability influences effectiveness of MCID and PASS in predicting patient improvement following cervical spine surgery
P Shahi, O Maayan, T Subramanian, N Singh, S Singh… - The Spine Journal, 2023 - Elsevier
BACKGROUND CONTEXT There are two schools of thought for the interpretation of Neck
Disability Index (NDI)-minimal clinically important difference (MCID) and patient acceptable
symptom state (PASS). MCID is commonly utilized for assessing spine surgery outcomes
and is defined as the smallest change in the NDI following surgery that would be clinically
significant for the patient. PASS is an absolute postoperative NDI score, unlike MCID which
is a change score, below which patients are expected to achieve an acceptable symptom …
