Patient understanding of the importance of statin use in the perioperative period.

OBJECTIVE: Perioperative hydroxy-3-methyl glutaryl coenzyme A reductase inhibitors (statins) have been shown to decrease morbidity and mortality after noncardiac surgery. The objective of this study was to assess patient understanding of the potential benefits of perioperative statins in a select population already on chronic therapy. A secondary aim was to determine the frequency with which patients recalled having a discussion with their provider regarding perioperative statins. DESIGN: Survey. SETTING: Teaching hospital. PARTICIPANTS: Patients taking daily statins presenting to a preoperative medical evaluation clinic were offered a 12-question survey that assessed their understanding of the potential benefit of taking the medication in the perioperative period. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: One hundred thirty-two patients completed the questionnaire. The mean age was 68.3 years (standard deviation, 9.0); 42% were female. The most frequent surgical referral to the clinic was orthopedics, at 36%. The most common statin prescribed was atorvastatin, in 35% of patients. Twenty-seven percent of patients (n = 36) recognized that perioperative statins are beneficial; 44% of these patients (n = 14) cited decreased cholesterol during the procedure as the reason, representing 12% of the total sampled population. Twenty-two percent (n = 8) of those recognizing the benefit of perioperative statins identified a decrease in the risk of heart attack or death as the reason. This represented only 6% of the total sample. One percent of surgeons mentioned statins in relation to the planned surgery; 2% of primary or prescribing physicians mentioned the medication in relation to surgery. CONCLUSIONS: This study suggested low patient understanding of the potential importance and reasons for perioperative statins. In addition, this study also suggested that the information regarding the importance of perioperative statins is not being relayed to the patient at the level of the surgeon or primary care physician. All physicians involved in perioperative care can offer improved patient education to promote compliance with statin therapy in hopes of a favorable impact on perioperative outcomes.

Patient understanding of the importance of beta-blocker use in the perioperative period.

OBJECTIVE: Perioperative beta-adrenergic blockade has been shown to decrease morbidity and mortality after noncardiac surgery. The objective of this study was to determine patient knowledge of the importance of perioperative beta-blockade in a population already taking chronic therapy and to assess the effectiveness of medical and surgical providers in patient education regarding these benefits. DESIGN: Survey. SETTING: Teaching hospital. PARTICIPANTS: One hundred twenty-six patients taking daily beta-blockers presenting to a preoperative medical evaluation clinic completed a 12-question survey that assessed their understanding of the potential benefit of taking the medication in the perioperative period. INTERVENTION: None. MEASUREMENTS AND MAIN RESULTS: Mean coronary artery disease risk factors per individual were 3.2 (standard deviation, 1.5). Forty-nine percent indicated that beta-blockers are beneficial in the perioperative period. Of those identifying benefit, 8% recognized decrease in myocardial infarction or decrease in mortality as the reason. Sixty-nine percent of patients who identified perioperative benefit cited blood pressure control as the reason. This correlated to the 67% of the total sample who identified their indication for the medication as antihypertensive. Only 7% recalled their prescribing physician ever mentioning the beta-blocker in relation to surgery. The same percentage recalled their surgeon mentioning it in relation to the planned procedure. CONCLUSIONS: This study suggests low patient understanding of the potential importance and reasons for perioperative beta-blockade. Patients who recognized perioperative benefit identified antihypertensive versus cardioprotective effects. Clinicians can improve education of patients already taking daily beta-blockers regarding these potential benefits.
