Treatment Strategies, Patterns of Drug Use and Treatment Discontinuation in Men with LUTS Suggestive of Benign Prostatic Hyperplasia: The Triumph Project

Objectives: We aimed to describe treatment strategies for lower urinary tract symptoms suggestive of benign prostatic hyperplasia (LUTS/BPH), adherence to and persistence with pharmacological treatment and the association between the type of LUTS/BPH complaints and early treatment discontinuation. Methods: Within a large GP database (IPCI) in the Netherlands we identified all males ≥45 years newly diagnosed with LUTS/BPH during 1995-2000. Details on treatment were assessed from the electronic patient records. Logistic regression analysis was used to estimate the association between the type of main urinary complaints and early treatment discontinuation. Results: Of the 2214 men with incident LUTS/BPH, 1075 received pharmacological treatment and 238 underwent prostate surgery. The average adherence differed slightly between drugs: 67% for α-blockers, 73% for 5α-reductase inhibitors and 71% for combination therapy. 26% of the treated patients discontinued treatment early. The probability of early discontinuation was higher if patients mainly expressed one type of complaint: voiding (ORadj 3.38; 95%CI: 1.89-6.04), post micturition (ORadj 2.37; 95%CI: 1.15-4.87) or storage symptoms (ORadj 1.85; 95%CI: 1.16-2.95) as compared to patients expressing a combination of symptoms. The risk of early discontinuation was higher if patients had a normal PSA measurement. Older age and a higher chronic disease score protected against early treatment discontinuation. Conclusions: Almost half of newly diagnosed LUTS/BPH patients are pharmacologically treated, and a quarter discontinues very rapidly. Stopping early is more frequent among younger persons, persons with only one type of main urinary complaint, no other co-morbidity and a normal PSA.
