Evaluation of complications in patients with mandible fractures undergoing chronic kidney disease in the United States.

BACKGROUND

This research aims to assess the demographic characteristics, prevalence, outcomes, and complications in chronic kidney disease (CKD) patients following mandible fractures in the United States using a nationally representative database.

METHODS

We analyzed data from the National Inpatient Sample from 2010 to 2019 in the United States. Patients with mandible fractures were categorized into three groups based on the International Classification of Diseases, Ninth and Tenth Revisions (ICD-9-CM and ICD-10-CM): end-stage renal disease (ESRD), non-ESRD CKD, and healthy kidney function. Chi-squared tests and analysis of variance (ANOVA) were used to compare these groups. Additionally, multivariate regression analysis was performed to determine whether CKD is an independent risk factor for complications in patients with mandible fractures.

RESULTS

A total of 38,481 patients in the United States were estimated to have experienced mandible fractures between 2010 and 2019. The incidence rate of non-ESRD CKD in patients with mandible fractures significantly increased over time, while the prevalence of ESRD remained stable during the ten-year period. Compared to the healthy kidney function group, patients with chronic kidney disease exhibited higher hospital costs, longer hospitalization durations, and higher in-hospital mortality rates. Additionally, they had greater odds ratios for most of the investigated complications.

CONCLUSIONS

This study revealed a steady annual increase in the morbidity rate of non-ESRD CKD among patients with mandible fractures, while ESRD prevalence remained stable over ten years. We observed a close association between chronic kidney disease and the prognosis of patients with mandible fractures. Clinicians should prioritize preventive measures and appropriate management of mandibular fractures in patients with CKD.
