Prevalence of opioid and benzodiazepine use in adult patients with the exstrophy-epispadias complex

Introduction: Bladder exstrophy (BE), cloacal exstrophy (CE), and epispadias (E) are variants of the exstrophy-epispadias complex (EEC). These children require opioids and benzodiazepines to achieve pain management and immobilization for a lifetime of surgeries. It is hypothesized that these children would be sensitized to opiates and benzodiazepines as adults. The objective was to identify incidence of opiate and benzodiazepine use in adult EEC patients. Methods: A US Health network, TriNetX Diamond was queried from 2009 to 2022. Incidence of prescriptions for benzodiazepines and opioids were calculated for adults aged 18–60 years with a diagnosis of BE, CE, or E. Results: A total of 2627 patients were identified: 337 with CE, 1854 patients with BE, and 436 with E. Of these, 55.5% of CE, 56.4% of BE, and 41.1% of E had received any opioid prescription. Non-EEC controls had lower rates of opioids at 0.3%. E had a lower likelihood than BE or CE of receiving opioids (p < 0.0001, p < 0.0001). Benzodiazepines were prescribed in 30.3% of CE, 24.4% of BE, 18.3% of E, and 0.1% of controls. CE had a higher likelihood of benzodiazepines than both BE and E (p = 0.022, p < 0.001, respectively). E group had the lowest likelihood of benzodiazepine prescription (p = 0.007 when compared to BE) and all groups were significantly higher than controls (p < 0.0001 for all comparisons). For BE, females were more likely to be prescribed opioids (p = 0.039) and benzodiazepines (p = 0.027) than males. Sub-analyses revealed BE females had higher rates of surgical procedures (general, cardiac, gastrointestinal, and maternity) and chronic diagnoses (generalized anxiety disorder, major depressive disorder, chronic pain) compared to males with BE. Older age was associated with higher likelihood of opioid or benzodiazepine prescriptions in BE (p < 0.001), CE (p = 0.004), and E (p = 0.002). Discussion: Across the EEC, adult patients with the most severe anomalies of CE were more likely to have received opioids and benzodiazepines. Females with BE were prescribed more opioid and benzodiazepines than males with BE. Mirroring the US population, female sex and increasing age were associated with higher rates of prescriptions, chronic diagnoses, and surgical procedures. Limitations include the lack of granular data and ability to correlate results with childhood surgeries. Conclusion: Adult EEC patients have higher rates of opioid and benzodiazepine prescriptions, with a high percentage of co-prescribing when compared to healthy controls. Across the spectrum, those with more severe anomalies, female sex, and increasing age were more likely to have received prescriptions.
