Abstract
Purpose
Pediatric cochlear implantation is performed on an outpatient basis in an inconstant way. The aim of this study is to assess the feasibility of day-case pediatric cochlear implantation by determining the acceptability of outpatient-to-inpatient conversion rate (acceptability threshold of 5%) and to assess the safety by comparing outpatient and inpatient postoperative events. We also want to identify conversion predictive factors.
Methods
We conducted a monocentric retrospective study including 267 cases aged 6 months to 18 years who underwent unilateral cochlear implantation between 2016 and 2020. This population was divided into two groups: outpatient group (190 cases) and inpatient group (77 cases).
Results
Among the 190 cases scheduled as day surgery, 9 cases required conversion to conventional hospitalization which leads to an outpatient-to-inpatient conversion rate of 4.7%. Postoperative nausea and vomiting (PONV) were involved in all cases of conversion. Conversion predictive factors were the presence of an inner ear malformation at risk of gusher (OR 32.51, 95% CI [4.98–370.27], p 0.001) and the intraoperative administration of morphine (OR 8.52, 95% CI [1.38–86.84], p 0.035). There was no statistically significant difference in immediate postoperative complications (outpatient 14.2% vs inpatient 16.9% p 0.715), early-stage complications (outpatient 12.6% vs inpatient 10.4% p 0.812) and early-stage unplanned consultations (outpatient 4.7% vs inpatient 3.9% p 0.748) between outpatient and inpatient groups. Unplanned readmissions were found only in the outpatient group.
Conclusion
Day-case pediatric cochlear implantation is a feasible and safe procedure even in infants. The outpatient-to-inpatient conversion rate of 4.7% is considered acceptable but requires anticipation of human and accommodation needs. No causes of conversion were life-threatening. The risk of postoperative complications and unplanned consultations are not influenced by the mode of hospitalization. Special attention should be paid to the prevention of PONV and the presence of inner ear malformations.
