OBJECTIVE: To evaluate the association between the International Prostate Symptom Score (IPSS) bother question (BQ) and a validated disease-specific quality-of-life questionnaire, the Benign Prostatic Hyperplasia (BPH) Impact Index (BPH-II), using the BPH Registry and Patient Survey database. PATIENTS AND METHODS: The BPH Registry and Patient Survey is a multicentre, longitudinal, observational database of management practices and patient outcomes in a population of patients with BPH in the USA, managed with watchful waiting or pharmacotherapy. Men enrolled in the BPH Registry who completed the IPSS BQ and the four-item BPH-II at enrolment were identified. The association between the IPSS BQ score and the BPH Impact Index was assessed using Spearman rank correlation. RESULTS: At baseline (enrolment visit), 6439 men (mean age 66 years) completed the IPSS BQ and the BPH-II. The mean (sd) score of the IPSS BQ was 2.5 (1.4) and of the BPH-II was 2.8 (2.8). Based on responses to the BPH-II, at least half the men reported that their urinary symptoms were associated with physical discomfort, worry about their health, and bothersomeness. The IPSS BQ score was significantly correlated (P < 0.001) with the BPH-II (r = 0.68) and each of its four questions (physical discomfort, r = 0.52; worry about health, r = 0.53; bothersomeness of trouble with urination, r = 0.67; and time kept from usual activities, r = 0.44). CONCLUSIONS: The IPSS BQ score has a strong and positive correlation with the BPH-II among men enrolled in the BPH Registry. The IPSS BQ is a convenient tool for assessing disease-specific quality of life when determining treatment strategies and evaluating treatment outcomes in men with BPH.
