Study Design. A retrospective review of instrumented spine registry from an integrated US healthcare system.

Objective. Investigate the 30-day readmission rate and risk factors after instrumented spine surgery.

Method. 30-day readmission rates were determined for 14,939 patients after an index spine procedure between 1/2009 and 3/2013. Data were analyzed with descriptive statistics, univariate, and multivariate logistic regression analysis.

Result. The average age of the cohort was 59 (SD= 13.4) and 52% were female. The 30-day readmission rate was 5.5%(821/14,939). The temporal pattern for readmission was: 17%(140) at week 1, 48%(394) at week 2, 72%(591) at week 3, and 100%(821) at week 4. The leading …
