Readmissions after major gynecologic oncology surgery (NSQIP)



abstract

Highlights

Readmission rate is dependent on several modifiable patient and treatment related factors.
Three quarters of readmission happen within two weeks of discharge from the hospital
Surgical site infections are the leading cause of readmissions

Objectives

To examine the underlying indications, timing, and risk factors associated with unplanned hospital readmissions after major surgery for a gynecologic malignancy.

Methods

This is a retrospective database cohort study utilizing the National Surgical Quality Improvement Program database (NSQIP). The association between risk factors with respect to 30-day unplanned readmission was modeled using logistic regression. Timing of readmission and the primary reason of readmission was abstracted from the database.

Results

Overall, the unplanned readmission rate was 6.5% (832/12,804). On multivariate analysis, operative time ≥ 3 h (OR 1.39, p < 0.001), open abdominal surgery (OR 2.2, p < 0.001), any complication prior to discharge (OR 1.6, p < 0.001), two or more additional surgical procedures (OR 1.34, p = 0.003), or cervical cancer as the site of primary disease (OR 1.30, p = 0.05) were noted to be independent predictors of readmission. To provide a convenient calculation of overall probability of readmission, we developed a nomogram of factors significantly predicting readmission. Overall, infections were a cause of 45% of the readmissions. Surgical Site Infections were the most common reason, accounting for 29.2% of all readmissions. A majority of the readmissions (approximately 75%) were within two weeks of discharge from the hospital.

Conclusions

Efforts to reduce readmission rates should focus on identifying patients at a high risk of readmission and reducing surgical site infections. Additionally, prospective evaluation of interventions targeted at reducing readmissions should focus on the first two weeks after discharge from the hospital.
