EP180/#431 Factors associated with emergency room readmission after elective surgery for ovarian cancer

Objectives

Our objective was to measure emergency room (ER) readmission, analyzing the consequent rate of hospital readmission, their causes and associated factors, and the morbidity and mortality of surgery in patients with ovarian cancer.

Methods

A retrospective study of 592 patients with ovarian carcinoma who underwent primary, interval or recurrence surgery were reviewed. An analysis of variables associated with ER readmission, hospital readmission and surgical complications were evaluated.

Results

Form 592 patients, median age was 51 years, the predominant type of surgery was interval laparotomy (52.9%); 46% underwent primary surgeries, and only 6 for recurrence. Complex surgeries resulted in a higher proportion of intraoperative complications (11.7%). The proportion of patients readmitted to ER was 11.8% (70 patients) of whom 12 patients were admitted more than once. The variables associated with ER readmission were prolonged time of surgery, intraoperative bleeding, longer hospital stay, the time of the day when the surgery was performed and postsurgical complications. The hospital readmissions were 4.2% and overall morbidity was 17.6%. In the multivariate analysis, the only variable associated with ER readmission was the presence of surgical complications (OR = 39.01). The variables independently associated with hospital readmission were entrance to the ICU (OR = 1.37), presence of surgical complications (OR = 2.85) and ER readmission (OR = 1.45).

Conclusions

ER readmission is an adverse event that represents the presence of symptoms/complications in patients. The evaluation of the ER readmission independently of the readmission to the hospital is important because it will allow modifying medical care behaviors.
