Insights
A small percentage of children require overnight admission after cochlear implantation (CI). Asthma and central nervous system abnormalities significantly increase admission likelihood, while outcomes remain similar for many admitted patients.
Area of Science:
- Pediatric Otolaryngology
- Surgical Outcomes Research
- Medical Informatics
Background:
- Cochlear implantation (CI) is a common procedure for pediatric hearing loss.
- Overnight postoperative admission is infrequent, with limited data on predictors.
- Understanding admission drivers is crucial for optimizing pediatric CI care.
Purpose of the Study:
- Identify variables associated with overnight admission after pediatric CI.
- Evaluate the impact of these variables on patient outcomes.
Main Methods:
- Analysis of the 2012-2015 American College of Surgeons' National Surgical Quality Improvement Program-Pediatric (ACS NSQIP-P) database.
- Identification of pediatric CI patients using CPT codes.
- Comparison of demographics, comorbidities, operative factors, and 30-day outcomes between ambulatory and admitted patients.
Main Results:
- 17.2% of 2943 pediatric CI patients were admitted postoperatively.
- Asthma (OR=2.2) and structural central nervous system (CNS) abnormalities (OR=2.1) were strong predictors of admission.
- Younger age and longer operation time were weak predictors; 42% of admitted patients had no identified risk factors.
Conclusions:
- Asthma and CNS abnormalities are key indicators for post-CI admission in children.
- A significant proportion of admitted patients lack identifiable risk factors, suggesting other admission drivers.
- Outcomes for admitted patients without identified risk factors were comparable to ambulatory patients.
Objectives:
A minority of children undergoing cochlear implantation (CI) are admitted overnight postoperatively, but there are little data on prognostic indicators. Our goal is to review national data to identify variables associated with admission and identify effects on outcomes.
Methods:
We analyzed data from the 2012-2015 American College of Surgeons' National Surgical Quality Improvement Program-Pediatric (ACS NSQIP-P) program use files. The CI patients were identified by CPT code. Demographics, comorbidities, anesthesia time, total operation time, 30-day complications, and 30-day readmission were compared between ambulatory and admitted patients.
Results:
A total of 2943 CI patients were included, with 17.2% of these admitted post implantation. Single variable analysis revealed multiple factors associated with admission post implantation. Multivariable analysis showed patients with asthma were 2.2 times ( P < .001; odds ratio [OR] = 1.484-3.227) and those with structural central nervous system (CNS) abnormalities 2.1 times ( P < .001; OR = 1.584-2.706) more likely to be admitted. Younger age ( P = .002; OR = 0.995-0.999) and longer operation time ( P < .001; OR = 1.003-1.006) were weak predictors. Two hundred sixteen patients lacked any factors but were still admitted. They had similar outcomes to ambulatory healthy patients.
Conclusion:
We identified factors associated with admission post-CI and higher readmission rates. Asthma and CNS abnormalities are strong predictors of admission post implantation. Forty-two percent of admitted patients lack any of these factors and have comparable outcomes to corresponding ambulatory patients.
