Making shared decisions with older men selecting treatment for lower urinary tract symptoms secondary to benign prostatic hyperplasia (LUTS/BPH): a pilot randomized trial.

BACKGROUND: Making high-quality decisions when selecting treatment for lower urinary tract symptoms due to benign prostatic hyperplasia (LUTS/BPH) requires a shared decision-making approach. However, older people with lower health literacy face barriers. The pilot study aimed to evaluate the feasibility of recruiting participants and evaluate the effectiveness of a multi-level intervention on decision quality for the treatment of LUTS/BPH. METHOD: In this 2-arm, randomized controlled trial, multi-ethnic Asian men aged ≥ 50 years with moderate or severe symptoms (IPSS ≥ 8 and/or QOL ≥ 3) and physicians were recruited at a Singapore public primary care clinic. Men were randomized to either physicians trained in shared decision-making and used a pictorial patient-reported symptom score (Visual Analogue Uroflowmetry Score) during the consultation or to physicians untrained in shared decision-making who did not use the score. Decision quality was measured using SDMQ-9 scores from men and their physicians after the consultation. RESULTS: 60 men (intervention [n = 30], control [n = 30]) receiving care from 22 physicians were recruited. Men's mean age was 70 ± 9 years: 87% were Chinese, 40% had no formal education, and 32% were of lower socioeconomic status. No difference in decision quality from the men's nor their physicians' perspectives was noted [for men: mean score = 70.8 (SD 20.3) vs. 59.5 (SD 22.4); adjusted p = 0.352] [for physicians: mean score = 78.1 (SD 14.1) vs. 73.2 (SD 19.8); adjusted p > 0.999]. CONCLUSION: It was feasible to recruit the intended participants. There was no difference in decision quality between men who used shared decision-making and usual care for the treatment of LUTS/BPH.
