Parotidectomy Trends Toward Outpatient for Benign Disease.

Objective: We evaluate the safety of outpatient parotidectomy. We evaluate factors that lead to planned admission and compare costs. We evaluate trends toward outpatient, and the outcomes of switching admission status, total versus superficial approach, and ambulatory versus hospital site.

Study design: Retrospective cohort study.

Setting: Single tertiary academic center.

Methods: Retrospective review of patients who underwent parotidectomy for benign tumors from 2018 to 2023.

Results: Of 370 parotidectomies performed, there were a planned 162 admissions and 208 outpatient procedures. A travel time > 60 minutes (odds ratio [OR] = 0.487, confidence interval [CI]: 0.296-0.803, P = .005) and total parotidectomy (OR = 0.448, CI: 0.226-0.89, P = .022) decreased the odds of a planned outpatient procedure. In a multivariable model, longer operative time increased the odds of switching to inpatient (n = 29, OR = 1.02, CI: 1.007-1.033, P = .002) and drain placement decreased the odds of switching to outpatient (n = 15, OR = 0.035, CI: 0.004-0.298, P = .002). There was no significant difference in surgical complications, phone calls, clinic visits, readmission rates, or recurrence between outpatient and inpatient. This remained true when comparing surgical facility and superficial versus total parotidectomy. After COVID was declared an emergency, there was a trend toward outpatient parotidectomy (72.7% vs 48.9%, P < .001), but no change in complication rates. At our institution, outpatient parotidectomy saved $3838 compared to overnight admission.

Conclusion: This study supports that outpatient parotidectomy is safe. This remained true for patients switching admission status, undergoing superficial or total parotidectomy, and having their operation at an ambulatory site. We demonstrate that institutions can safely increase outpatient parotidectomy rates and outpatient parotidectomy is cost effective.
