Management Patterns for Benign Prostatic Hyperplasia: Impact of a Patient Decision Aid.

INTRODUCTION

Decision aids aimed at men with benign prostatic hyperplasia used in clinical trials have decreased the use of procedures and affected elements of decisional quality. We employed an online, interactive decision aid for men with benign prostatic hyperplasia as a routine part of care with a urologist and tracked subsequent treatment choice. We further evaluated the role of patient preferences on treatment selection.

METHODS

Men scheduled for a new patient visit with a urologist for benign prostatic hyperplasia at a single tertiary care center were invited to use a decision aid prior to their visit. We compared treatment patterns in men who used the decision aid to a usual care group identified prior to the decision aid's introduction. Latent class analysis identified clusters of patients by their treatment preferences, which were then compared to their treatment choice.

RESULTS

The rate of procedures in the decision aid group was significantly lower than in the usual care group (6% vs 15%; p=0.0250), matching the rates reporting a procedure as their preferred treatment choice in the post-consult questionnaire (5% vs 15%; p=0.0082). Of the patients in our project 36% had never tried an alpha blocker prior to their urology consult. Latent class analysis found 2 clusters of patient preferences but without a significant association with final treatment selection.

CONCLUSIONS

Use of a decision aid was associated with a significant decrease in procedural management of benign prostatic hyperplasia. A high proportion of patients were evaluated by urologists without exhausting primary care management options.
