Cost-consequence analysis of penile prosthesis implantation in outpatient setting in Spain

ObjectiveTo evaluate the clinical and economic consequences of penile prosthesis (PP) implantation in an outpatient setting compared to its implantation in an inpatient setting in the Spanish National Health System (NHS).MethodsA cost-consequence model was developed to estimate the total cost per patient (euro, 2021) of PP implantation in the outpatient or inpatient setting and the total cost in a hypothetical future scenario in which the annual percentage of patients implanted in an outpatient setting could reach 50% (n = 349) to 70% (n = 488). Consequences included health resource consumption, total time gained/per patient and bed occupation.ResultsPP implantation in the outpatient vs inpatient setting resulted in cost savings of euro962/per patient and 1 hospital bed day per procedure. Increasing the percentage of patients implanted in outpatient setting to 50% and 70% could generate annual savings of euro279,657 and euro413,785, respectively, compared to the current scenario (8.3% PP implantation in the outpatient setting). If the patients currently undergoing surgery in the inpatient setting underwent surgery in the outpatient setting, 328 additional patients/per year could be admitted.ConclusionsPP implantation in the outpatient setting has been shown to have similar outcomes and to yield cost savings compared to inpatient surgery within the Spanish NHS.
