(258) Trends in Prevalence, Incidence and Pharmacological Prescriptions for Premature and Delayed Ejaculation – A Claims Database Analysis

Abstract Introduction Premature (PE) and delayed (DE) ejaculation are common male sexual dysfunction disorders. Despite a community-reported prevalence of approximately 30% for PE and 5% for DE, the clinical prevalence, incidence, and rates of pharmacological prescriptions for both disorders remain under-investigated in the literature. Objective Our objective is to assess the trends in prevalence, incidence, and pharmacological treatment of PE and DE using a large claims database. Methods The TriNetX Research database, a large insurance claims database, was queried to identify all adult (≥18 years) males that were evaluated from January 2012 through December 2022. The number of men diagnosed with PE (ICD-10 F52.4) and DE (F52.32 and N53.11) was compared to the total number of men evaluated using six-month intervals (January-June, July-December) to calculate percent prevalence and incidence. A chi-squared test of linear trends was performed for prevalence and incidence. Rates of prescribed treatments were calculated comparing the number of men receiving the treatment to the total number of men with the assessed disorder using six-month intervals for PE and one-year intervals for DE. Results A total of 17,647 adult males with a diagnosis of PE and 6,304 adult males with a diagnosis of DE were identified from January 2012 to December 2022. The prevalence and incidence for both disorders are found in Figure 1. The chi-square test for trends showed a significant increasing trend in the prevalence of PE (χ2 = 303.44, p-value = <0.0001) and DE (χ2 = 314.14, p-value = <0.0001) and incidence of PE (χ2 = 6.40, p-value = 0.0114) and DE (χ2 = 187.43, p-value = <0.0001). In the final period, 63.5% males with PE and 33.4% males with DE received at least one medication of the investigated therapies. The most common medications prescribed to men with PE were phosphodiesterase-5 inhibitors (25.7%), paroxetine (17.4%), topical anesthetics (13.4%), and sertraline (12.2%). The most common medications prescribed to men with DE were testosterone (11.7%), bupropion (12.2%), and cabergoline (10.0%). The prescription rates of all of the investigated medications for PE and DE are shown in Figures 2 and 3, respectively. Conclusions In this large US claims database analysis, premature and delayed ejaculation are overall diagnosed at low but increasing rates. Furthermore, the rates of pharmacological prescriptions for PE remains relatively low, despite pharmacotherapy being recommended as first-line options under the current guidelines. Additional research is necessary to investigate the long-term efficacy of individual medications for both PE and DE. Disclosure No.
