Accurately Determining Patients Who Underwent Robot-Assisted Surgery: Limitations Of Administrative Databases.

The comparative effectiveness of open vs. robot-assisted radical prostatectomy for prostate cancer remains a controversial debate in urology. Its evaluation has largely relied on observational studies using administrative claims.

In this report, we compare the accuracy of ICD-9 procedure codes vs. an itemized charge description methodology before and after the introduction of an ICD-9 code specifically identifying RARP in October 2008. We find that prior to 2008, charge description and ICD-9 procedures codes were poorly correlated, whereas after 2008, they were highly correlated. These findings call for a cautious interpretation of comparative effectiveness studies of ORP vs. RARP relying on ICD-9 procedures codes, particularly before October 2008.
