RESUMEN
OBJECTIVES: This study aims to determine the overall incidence of medical and surgical admissions related to non-tuberculous mycobacterial cervicofacial lymphadenitis (NTMCL) and determine if rates vary by geographic region in the US. It also aims to assess if the relative frequency of varying treatment modalities for NTMCL differ among geographic regions. STUDY DESIGN: Population-based inpatient registry analysis. SETTING: Academic medical center. METHODS: The Kids' Inpatient Database (2016 and 2019) was used to determine NTMCL-related admissions and common head and neck procedures performed during these admissions were identified. Analysis was performed on regional differences in demographic factors and procedures performed during NTMCL-related admissions. RESULTS: There were 159 weighted admissions (1.31 per 100,000) for NTMCL in 2016 and 2019 in the US, with the Midwest having the highest proportion of NTML-related admissions (1.59:100,000). NTMCL-related admissions were 2.21 times as likely to be elective rather than non-elective in the Midwest when compared to all other geographic regions (p = 0.038). The Midwest was 2.83 times as likely to treat with surgery (p = 0.011), while the Northeast was negatively associated with performing procedures (OR 0.38; p = 0.026). In the Midwest, significantly more excisional surgeries were preformed when compared to other regions, with an OR of 2.98 (p = 0.003). CONCLUSION: The Midwest had the highest incidence of pediatric NTMCL-related admissions and was more likely to perform excisional surgery as primary NTMCL treatment. Regions that rarely see pediatric NTMCL have a more inconsistent approach to management.
