Controlled Trial to Increase Detection and Treatment of Osteoporosis in Older Patients With a Wrist Fracture

BACKGROUND: Osteoporosis is a progressive condition that causes a loss of bone mass, skeletal fragility, and fractures. Fractures result in pain, disability, deformity, and death. Osteoporosis is a major population health problem affecting 1.4 million Canadians, 25% of women and 12% of men over the age of 50 years. Current guidelines recommend aggressive secondary prevention in patients with osteoporosis who have suffered a fracture, because these patients have as high as a 20% risk of fracture in the following year, and because there are now proven efficacious treatments that can reduce this risk by 40-60%. Nevertheless, recent studies have shown that these patients are under-recognized and under-treated, demonstrating a care gap between evidence-based best practice and usual care. All patients with osteoporotic fractures (i.e., of the hip, vertebrae, or wrist) benefit from treatment. However, patients who present with a wrist fracture may be best suited to an intervention to improve secondary prevention practices, because wrist fractures are "sentinel events" in the natural history of osteoporosis: they are common, easily diagnosed, always present to medical attention, and occur years before the more devastating and costly fractures of the hip and vertebrae.

OBJECTIVES: The primary objective of this study is to improve the quality of care for patients who present to the ED with osteoporosis and a fracture of the wrist, by increasing the use of proven efficacious osteoporosis treatment. This is the primary study outcome, and it is defined as starting any one of hormone replacement therapy, a bisphosphonate, raloxifene, or calcitonin within 6 months of a fracture of the wrist.

HYPOTHESIS: A quality improvement intervention directed at patients and their primary care physicians will increase the use of proven efficacious osteoporosis treatment. The intervention itself has multiple components that include: a notification system and patient-specific reminders for primary care physicians, locally developed treatment guidelines endorsed by opinion leaders, and patient education and counseling. The study hypothesis will be tested by comparing the intervention to usual care controls, in a prospective nonrandomized controlled trial.

SPECIFIC AIMS: To determine whether the proposed intervention can-

• 1. Increase the use of proven efficacious osteoporosis treatment in patients with a fracture of the wrist,
• 2. Increase appropriate use of bone mineral density testing,
• 3. Increase patients' knowledge of osteoporosis and satisfaction.
