Abstract | INTRODUCTION: METHODS: A retrospective analysis of the Nationwide Inpatient Sample (years 2000-2008) was used; we selected cases with a primary diagnosis of a periapical abscess with/without sinus involvement. The demographic characteristics and outcomes were examined. Each individual hospitalization was the unit of analysis. RESULTS: During the 9-year study period, a total of 61,439 hospitalizations were primarily attributed to periapical abscesses in the United States. The average age was 37 years, and 89% of all hospitalizations occurred on an emergency/urgent basis. The mean length of stay was 2.96 days, and a total of 66 patients died in hospitals. Medicare, Medicaid, and private insurance plans paid for 18.7%, 25.2%, and 33.4% of hospitalizations, respectively. Uninsured patients accounted for 18.5% of hospitalizations. Significant predictors that influenced both hospital charges and length of stay included age, race, insurance status, a periapical abscess with sinus involvement, geographic region of country, the Charlson comorbidity index, and the year of study (P < .05). CONCLUSIONS: The current study highlights the increasing burden of hospitalization of patients with periapical abscesses over a 9-year study period from 2000 to 2008. The high-risk groups likely to seek a hospital setting for the treatment of periapical abscesses were identified as were groups associated with higher hospital charges and a longer length of stay.
