Cost analysis of objective resident cataract surgery assessments.

Purpose: To compare 8 ophthalmology resident surgical training tools to determine which is most cost effective.

Setting: University of Rochester Medical Center, Rochester, New York, USA.

Design: Retrospective evaluation of technology.

Interpretation of urine drug testing results in patients using transdermal buprenorphine preparations for the treatment of chronic noncancer pain.

Objective: To determine whether the prevailing liquid chromatography and tandem mass spectroscopy assay (LC-MS/MS) assay designed to monitor buprenorphine compliance of the sublingual formulation used in the substance abuse treatment setting can be extrapolated to the transdermal formulation used in the chronic pain treatment setting, which is 1000-fold less concentrated.

Design: Retrospective chart review.

Subjects: Self-reported compliant patients using the transdermal or sublingual formulations of buprenorhphine.
