as four or greater priapism encounters. Univariate analysis was performed using Student's t-test, Pearson chi-square test, and Kruskal-Wallis H test. A multivariable logistic regression model was used to determine predictors of recurrent priapism encounters.RESULTS: 5,872 patients had a hospital encounter for priapism within the study period and locations. Of these patients, 4,217 had a single encounter, 1,208 had two or three priapism encounters, and 447 had four or greater. Patients with recurrent priapism had an average of 7.82 encounters. (Table 1) On multivariate analysis, factors increasing the odds of recurrent visits included Black race (OR 1.83, p<0.005), Hispanic race (OR 1.49, p<0.005), Asian race (OR 2.79, p<0.005), non-private insurance (e.g. Medicaid 1.63, p<0.005), and sickle-cell anemia (OR 5.08, p<0.005). Factors decreasing odds of recurrent visits included age>45 (OR 0.52, p<0.005), spinal cord injury (OR 0.05, p<0.005) and diagnosis of erectile dysfunction (OR 0.34, p<0.005).CONCLUSIONS: It appears that approximately 7.6% of priapism patients will go on to have recurrent priapism. There are several demographic and medical risk factors that should be considered when treating and counseling patients. Further longitudinal studies should be aimed at confirming these risk factors and ways in prevention.
