Factors Associated with 30-Day Readmission after Endoscopic Transsphenoidal Surgery: The Critical Role of Dedicated Endocrinology Discharge Coordination.

OBJECTIVES

This study aimed to identify demographic, clinical, and operative factors of unplanned 30-day readmission following endoscopic transsphenoidal surgery (ETS).

DESIGN

Single-center retrospective study.

SETTING

A tertiary academic medical center based in New York, NY.

PARTICIPANTS

A total of 386 adult patients who underwent non-emergent ETS for pituitary adenomas between March 2009 and May 2020.

MAIN OUTCOME MEASURES: The primary outcome was 30-day unplanned hospital admission. Clinical and demographic characteristics were analyzed using χ 2 and Student's t -tests. For factors with p -value <0.1, multivariate logistic regression models were constructed to estimate the adjusted odds of 30-day readmission across predictive factors.

RESULTS

Of 386 patients who received ETS, 29 (7.5%) patients required readmission within 30 days of discharge. Eleven (2.8%) patients were readmitted for complications related to electrolyte derangements (syndrome of inappropriate antidiuretic hormone, hyponatremia), followed by 5 (1.3%) patients with epistaxis. On multivariate analysis, pituitary microadenomas ( p  = 0.032), transient diabetes insipidus (DI; p  = 0.021), and preoperative visual cranial nerve palsies (CN III/IV/VI; p  = 0.019) were associated with increased odds of 30-day readmission.

CONCLUSION

Patients with pituitary microadenomas, transient DI, and preoperative cranial nerve palsies were at an increased risk for unplanned 30-day readmission after ETS. Dedicated neuroendocrinology involvement is necessary in the postoperative period to reduce readmission risk in these patients. Identification and careful monitoring of these at-risk populations is necessary, as targeted postdischarge care may prevent readmission and improve both patient and hospital outcomes.
