Age, Steroid Use, Low BMD Predict Bisphosphonate Scrips


 

DENVER — Significant predictors of receiving a bisphosphonate prescription within 90 days of a fracture for women are a low bone mineral density score after a fracture, being aged 65-74 years, and oral corticosteroid use, according to the results of a study of 2,000 women.

Women with a bone mineral density (BMD) T score of −2.5 or less in the 90 days after a fracture were almost five times as likely to receive a bisphosphonate prescription than women with higher T scores, according to a poster presented by Carl Asche, Ph.D., at the annual meeting of the American Society for Bone Mineral Research.

Women who were aged 65-74 years at the time of fracture were almost twice as likely to receive a prescription, compared with women younger than 65. Similarly, women taking oral corticosteroids also were more likely to receive a bisphosphonate prescription wrote Dr. Asche of the pharmacotherapy department at the University of Utah, Salt Lake City.

Using electronic health records from Geisinger Health System from Jan. 1, 2000, to June 30, 2007, women 50 years of age and older who had had a fracture were included. They also had to have continuous electronic health record activity for at least 365 days before and after the date of the fracture. Women were excluded if they had a diagnosis of osteoporosis, a bone mineral density score of −2.5 or less at the time of the fracture, a fracture in the 6 months prior to the index date, or a diagnosis of conditions known to impact bone density and quality.

A total of 2,000 women met the inclusion criteria, but less than 10% (188) received a prescription for a bisphosphonate within 90 days of fracture. “Very few women aged [over] 50 receive treatment with an oral bisphosphonate after having a fracture, leaving them potentially vulnerable to future fractures,” he noted.

Disclosures: The study was supported by the Alliance for Better Bone Health—Procter & Gamble Pharmaceuticals and Sanofi-Aventis U.S., which co-promote Actonel. Dr. Asche reported that he has a significant financial relationship with Sanofi-Aventis U.S.
