Key result
Postoperative complications linked to ~391% higher readmission risk following adrenalectomy.
Why the study?
Risk factors for readmission following adrenalectomy and the resulting cost burden on the US healthcare system needed to be examined.
What are the risk factors and cost burden of 30- and 90-day readmissions following adrenalectomy?
Observational (n=20,494)
Yes
What are the risk factors and cost burden of 30- and 90-day readmissions following adrenalectomy?
Effect estimate: OR 4.91 (95% CI 1.98-12.16)
Prolonged initial hospital stays and postoperative complications significantly increase the risk of 30- and 90-day readmissions following adrenalectomy, adding substantial cost burden.
May warrant closer post-discharge surveillance after adrenalectomy; hypothesis-generating for interventions targeting complications and length of stay.
Background: Examining risk factors of readmission in adrenalectomy patients and estimated the cost burden of unplanned readmission on the United States' healthcare system. Methods: According to the Nationwide Readmission Database, 20,494 patients underwent adrenalectomy between 2010-2014. Demographics, comorbidities, clinical data, length of stay (LOS), annual case volume, and discharge disposition of 30- and 90-day readmission cohorts were compared to the non-readmitted cohort. Results: A total of 1,463 (7.9%) and 1,959 (12.7%) adrenalectomy patients were readmitted at 30 and 90 days after discharge, respectively. Prolonged initial hospital stays [odds ratio (OR) =1.93; 95% confidence interval (CI): 1.63-2.27] and postoperative complications (OR =4.91; 95% CI: 1.98-12.16) were associated with a higher risk of readmission. Complications were significantly more frequent in patients with a primary or secondary malignancy (OR =1.42; 95% CI: 1.23-1.64) and in patients undergoing a procedure at a low adrenalectomy volume hospital [hazard ratio (HR) =0.75; 95% CI: 0.62-0.91; P=0.003]. Readmission extended overall LOS by an average of 2.06 days, costing an additional $18,529.49 per admission. Conclusions: Readmission adds significantly to the burden of disease after adrenalectomy. Understanding contributing factors may identify strategies to reduce readmissions and improve healthcare for patients.

Hussein et al. (2022) conducted an observational in Adrenalectomy (n=20,494). Risk factors (prolonged stay, complications) vs. Non-readmitted cohort was evaluated on Readmission associated with postoperative complications (OR 4.91, 95% CI 1.98-12.16). Postoperative complications (OR 4.91; 95% CI 1.98-12.16) and prolonged initial hospital stays (OR 1.93; 95% CI 1.63-2.27) were associated with a higher risk of readmission following adrenalectomy.
