| アブストラクト | BACKGROUND: Real-world data on the pharmacological management of men who have lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH) are limited. OBJECTIVE: To characterize men with LUTS/BPH who had both storage and voiding symptoms and to evaluate treatment patterns in UK primary care. DESIGN, SETTING AND PARTICIPANTS: This was an observational study of men aged >/=45 years with a diagnosis, symptoms or therapies indicative of LUTS/BPH with both storage and voiding components. These men were identified from the large Health Improvement Network (THIN) database between 1 January 2004 and 30 September 2011. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Drug prescriptions and switching/discontinuation patterns for alpha(1)-blockers and antimuscarinics. RESULTS AND LIMITATIONS: We identified 8694 men with a median age of 66.0 (interquartile range [IQR], 59.0-74.0) years. Most (7850; 90.3%) received an alpha(1)-blocker, and 2167 (24.9%) received antimuscarinic therapy over a median of 2.1 years. The most commonly prescribed alpha(1)-blocker was tamsulosin (81.8%); most frequent antimuscarinics were tolterodine (41.0%), oxybutynin (37.2%) and solifenacin (35.7%). Concomitant prescription of alpha1-blocker and antimuscarinic therapy (within 30 days of each other) was received by 1160 men (14.8% of alpha(1)-blocker-treated men). Of alpha(1)-blocker recipients, 3024 (38.5%) discontinued during follow-up, while 1149 (53.0%) discontinued antimuscarinic therapy. Of 2167 men who received an antimuscarinic, 476 (22.0%) switched to another antimuscarinic. Of the three most commonly prescribed antimuscarinics, solifenacin had the lowest proportions of discontinuations (43.0%) and switches (15.3%), and the longest median duration of therapy (90 days, IQR 30-300). General practice consultations accounted for most resource use (5307.9 per 1000 patient-years). CONCLUSIONS: This study presents real-world management of men with LUTS/BPH who have both storage and voiding symptoms. The low proportion of men who received concomitant alpha(1)-blocker and antimuscarinic therapy suggests that some patients are sub-optimally treated in routine clinical practice. |
