Abstract
Prostate abscess is a severe complication of acute bacterial prostatitis. To date, a population-based analysis of risk factors and outcomes of prostatic abscess has not been performed. Using the National Inpatient Sample from 2010 to 2015, we identified rates of prostatic abscess among non-elective hospitalizations for acute prostatitis. Significant Elixhauser comorbidities and risk factors were analyzed using survey-weighted logistic regression. Additional survey-weighted regression models were constructed to analyze sepsis, in-hospital mortality, length of hospital stay (LOS), and total hospital charges. A weighted total of 126,103 hospitalizations for acute prostatitis was identified, with 6,775 (5.4%) hospitalizations with prostatic abscess. Numerous risk factors for prostatic abscess were identified, with a history of prostate biopsy (adjusted OR: 5.7; p < 0.001), complicated diabetes mellitus (adjusted OR: 3.23, p < 0.001), and urethral stricture (adjusted OR: 3.15; p < 0.001) having the greatest magnitude of developing abscess. Moreover, those diagnosed with prostatic abscess had increased odds of sepsis (adjusted OR: 1.71, p < 0.001), in-hospital mortality (adjusted OR: 2.73, p < 0.001), LOS (adjusted Incidence Rate Ratio: 1.86, p < 0.001), and total hospital charges (adjusted Ratio: 2.06, p < 0.001). Numerous risk factors were associated with the development of prostatic abscess, with those diagnosed experiencing greater odds of sepsis, in-hospital mortality, longer LOS, and greater hospital charges. Ultimately, better understanding of risk factors associated with this condition will enable clinicians to identify patients at high risk, thereby expediting and tailoring management.
