Decision tree analyses of key patient characteristics in Middle Eastern/North African and Latin American men treated with long-acting and short-acting PDE5 inhibitors for erectile dysfunction
Abstract Background : Phosphodiesterase type 5 ( PDE5 ) inhibitors have discontinuation rates as high as 60 % in men with erectile dysfunction . Treatment satisfaction has been significantly associated with treatment continuation . Underst and ing key characteristics in terms of treatment preference , relationship , and lifestyle issues could provide direction on how to improve compliance with PDE5 inhibitor treatment globally . Objective : The objective was to identify subgroups of interest in the pooled data base of two observational studies conducted in Latin America ( LA ) and Middle East/North Africa ( MENA ) exploring patient characteristics and prescription of either a long- or short-acting PDE5 inhibitor at baseline . Methods : Two identical prospect i ve , non-interventional , observational , studies in MENA ( N = 493 ) and LA ( N = 511 ) treated men with an ‘ on dem and ’ ( pro re nata , PRN ) PDE5 inhibitor ( sildenafil , tadalafil , vardenafil , or lodenafil ) during 6 months . In this post-hoc meta- analysis of two observational studies with equal design , pooled data were analyzed to determine patient characteristics and PDE5 inhibitor prescribed/used most likely to be associated with patient expectations , satisfaction , self-esteem , and patient – partner relationships . Decision tree analyses , with and without weighting , were used to identify and describe key features . Results : In each analysis of patient expectations , patient – partner relationship , and self-esteem , we describe the two major subgroups at baseline for each decision tree . Analyses of patient expectations and sexual self-esteem revealed that patients prescribed long-acting PDE5 inhibitors ( 59 % ) highlighted the importance of treatment effect duration , second to partner satisfaction with treatment , while patients prescribed short-acting PDE5 inhibitors ( 32 % ) placed less importance on treatment effect duration but considerable importance on treatment effect lasting until intercourse completion . Further insights regarding patients , partner relationship characteristics , and treatment expectations were identified . Conclusion : Our analyses have described key characteristics , such as self- and partner perceptions , sexual attitudes , and treatment expectations in relation to the patients ’ country and prescribed treatment , which might guide treatment decisions in MENA and LA men with ED
