Characterization of combined endoscopies and aerodigestive care: An analysis of utilization and financial feasibility

Background: Aerodigestive care is one model of multi-disciplinary care, which is a valuable tool for both providers and patients. Aerodigestive care models are associated with improved outcomes, reduced anesthesia exposure, reduction in hospital admissions, and fewer days of missed work or school. This is the first study to explore national usage and cost trends in combined endoscopy utilization to identify gaps in care and the potential for financial resource optimization. Methods: Data from the Healthcare Cost and Utilization Project (HCUP) Kid’s Inpatient Sample (KID) was used from 2016 and 2019. Diagnoses and procedures were identified using ICD-10 codes, for patients with hospital length of stay less than 1 day. Demographic data were identified, and survey-weighted means and proportions were computed. Bivariate comparisons were made using Rao Scott Chi-Square tests. National estimates of charges were computed with discharge weights, developed using the American Hospital Association (AHA) universe. Key results: White, high-income patients, and those at urban teaching hospitals received the greatest proportion of combined endoscopic procedures. The cost/charges associated with combined endoscopies are less than for separate gastrointestinal (GI) or airway only endoscopies combined. However, combined procedures comprise a smaller share of national aggregate cost. Conclusions: National utilization trends highlight racial and socioeconomic disparities and suggest differences in access based on hospital characteristics, despite the reduced cost/charges of the combined procedure. For patients with a need for combined aerodigestive procedures, there appears to be a cost-savings opportunity to increase efforts for combined procedures at the level of the clinician or hospital.
