The main objective of the research was to study the baseline quality of life, comorbidities, and demographics as the prospective outcome after lumbar spine surgery. The patients who are undergoing lumbar spine surgery within the span from June 2009 to December 2012 were being reviewed thoroughly. The type of surgery was calculated with the patient’s conditions based on the comorbidities, demographics, symptoms, and the duration of those symptoms. Once the surgery is done, the patients are kept under observation based on their visits or readmission to the hospitals within 30 days, 90 days, or 1 year. A score has been calculated according to the outcome of the patients and that was being used for internal validation of the surgery.

As a result of 2996 lumbar spine surgery cases, it has been observed that only 7% of patients had come for a revisit within 30 days. The rate of 30-day readmission was 12%. 3% of patients needed to do reoperation within 90 days. 56% of patients recovered and went through improvements within 1 year after the surgery. Based on this study the doctors can offer lumbar spine surgery for critical patients for a better prospective outcome and improvement.
