Reasons for discontinuing intracavernous injection therapy with prostaglandin E1 (alprostadil) - 07/09/11
Abstract |
Objectives. To clarify the reasons why experience with self-injection therapy for erectile dysfunction shows high dropout rates.
Methods. We studied 86 patients 36 to 76 years old who had been on home treatment for at least 3 months. Sixty-nine patients (80%) were continuing to use injections, and 17 (20%) had discontinued the treatment. Patients were evaluated by interview and clinical examination.
Results. Patients still in the program used one injection every 2 weeks, and those who had given up treatment had used one injection in 3 weeks (P = 0.31). They were in the program for 39 ± 27 and 16 ± 22 months (P = 0.002), respectively, and had used 50 (95% confidence interval [CI] 21 to 91) versus 12 (95% CI 4 to 20) injections, respectively (P < 0.0001). Injections producing unsatisfactory penile rigidity, prolonged erections, hematoma at injection site, corporal fibrosis, secondary penile deviation, and mean estimated duration of a pharmacoinduced erection showed no significant differences. Patient satisfaction (P = 0.02), estimated partner satisfaction (P = 0.02), increase in self-esteem (P = 0.01), and negligible effort in performing injections (P = 0.001) all showed significantly better results for those still in the program.
Conclusions. Reasons for dropout from self-injection therapy are not based on objective side effects and discomfort. Patients leaving the program are less motivated, less satisfied with the quality of pharmacoinduced sexuality, consider the effort to perform injections to be substantial, and have not achieved improved self-esteem.
