Aim Nocturia frequency has been used as a measure of treatment efficacy for nocturia even though fluctuation of the symptom over time has been well described in the literature. Additionally, given the multifactorial causal pathway and clinically relevant comorbidities, frequency alone may be an insufficient marker of treatment direction. The aim of this study was to investigate factors associated with nocturia‐related bother to identify additional variables that may capture the impact of nocturia, direct clinical care and have potential to quantify treatment outcome. Methods Prospective data from tertiary hospital Urology and Continence cohorts were matched for identical variables to generate a sample of 204 datasets. Descriptive statistics were obtained to describe the two cohorts. Characteristics of patients were evaluated across levels of nocturia frequency and nocturia‐related bother using nonparametric methods; statistically significant differences between groups in each cohort were established. Results Nocturia frequency alone does not comprehensively reflect attributable bother. Five sleep variables (poor quality sleep, short time to first awakening to void, less than 7 hours of total sleep, primary sleep latency, and daytime sleepiness) and daily urinary urgency were significantly associated with high nocturia‐related bother. Attributable bother, despite high‐frequency nocturia, was minimized by male gender, lack of daily urinary urgency and good sleep quality. Poor health status, urinary urgency and sleep latency were associated with nocturia frequency. Conclusions Items of importance to individuals with nocturia have been identified from patient data. These variables have the potential to sit alongside change in nocturia frequency as potential markers of treatment response.
