The Upstate New York Surgical Quality Improvement Opioid Reduction Project.

Over 5 million Americans currently abuse prescription opioids. Patients' first exposure to opioids is often after surgery. Few opioid guidelines account for the challenges to health care institutions that serve wide catchment areas.

The Association of Vitamin D Status and Pre-operative Physical Activity in Patients with Hip or Knee Osteoarthritis.

Background: Vitamin D is important for musculoskeletal health and may have significant implications for maintaining physical activity in elderly patients. Our goal was to investigate whether serum 25-hydroxyvitamin D (25OHD) levels are associated with pre-operative physical activity in patients who are offered elective knee or hip joint replacement surgery.

Methods: We performed a single-center, retrospective analysis of patients who had elective knee or hip replacement surgery from 2002 to 2012.
