A growing body of literature has been produced on the potential role of statins in reducing perioperative cardiac events in patients undergoing non-cardiac surgery. However, evidence remains inconsistent and little is known about the patterns of perioperative statin use in routine care. To examine patterns of perioperative statin initiation among adults undergoing non-cardiac elective surgery in the US. Using data from a large US healthcare insurer, we identified patients ≥18 years who underwent moderate- to high-risk non-cardiac elective surgery between 2003-2012 and initiated statins within 30 days before surgery. We evaluated temporal trends of statin initiation and patient characteristics. In a matched analysis, we assessed the effect of temporal proximity to surgery on the likelihood of statin initiation. Of 460,154 patients undergoing surgery, 5,628 (12 per 1000 patients) initiated a statin within 30 days before surgery. Statin initiation increased from 8 per 1000 patients in 2003 to 15 in 2012 (p = .0022). The increase was more pronounced among patients undergoing vascular surgery (149 initiators per 1000 patients by the end of 2012) and with revised cardiac risk index (RCRI) score ≥2 (72 per 1000 patients). Proximity to surgery, in particular vascular surgery, was predictive of statin initiation. Despite the lack of robust evidence, perioperative statin initiation progressively increased from 2003 to 2012, particularly among patients undergoing major vascular surgery and with higher RCRI score. These trends were largely attributable to the initiation of statins in anticipation of non-cardiac surgery rather than routine dyslipidemia treatment.
