title: Risk Factors for Priapism Readmission.
abstract: Priapism is a urologic emergency with a tendency to recur in some patients. The frequency of, time to, and risk factors for priapism recurrence have not been well characterized.
  
  
  
  To identify predictors of priapism readmission.
  
  
  
  We used the New York Statewide Planning and Research Cooperative System database to identify patients presenting to emergency departments with priapism from 2005 through 2014. Patients were tracked up to 12 months after initial presentation. Proportional hazards regression was used to identify risk factors for priapism readmission.
  
  
  
  Readmissions for priapism.
  
  
  
  The analytic cohort included 3,372 men with a diagnosis of priapism. The average age at first presentation was 39 ± 18 years and 40% were black. Within 1 year, 24% of patients were readmitted for recurrent priapism, 68% of whom were readmitted within 60 days. On multivariate analysis, sickle cell disease (hazard ratio [HR] = 2.5, 95% CI = 2.0-3.0), drug abuse or psychiatric disease (HR = 1.9, 95% CI = 1.6-2.2), erectile dysfunction history (HR = 1.9, 95% CI = 1.5-2.3), other than commercial medical insurance (HR = 1.2, 95% CI = 1.0-1.4), and inpatient admission for initial priapism event (HR = 0.5, 95% CI = 0.4-0.6) were significant risk factors for readmission.
  
  
  
  Nearly one fourth of patients with priapism were readmitted for recurrent priapism within 1 year of initial presentation. Most readmissions were within 60 days. Future research should focus on strategies to decrease recurrences in high-risk patients.
