Pharmacist Interventions to Improve Cardiovascular Disease Risk Factors in Diabetes

Abstract

OBJECTIVEThis systematic review and meta-analysis of randomized controlled trials (RCTs) assesses the effect of pharmacist care on cardiovascular disease (CVD) risk factors among outpatients with diabetes.RESEARCH DESIGN AND METHODSMEDLINE, EMBASE, CINAHL, and the Cochrane Central Register of Controlled Trials were searched. Pharmacist interventions were classified, and a meta-analysis of mean changes of blood pressure (BP), total cholesterol (TC), LDL cholesterol, HDL cholesterol, and BMI was performed using random-effects models.RESULTSThe meta-analysis included 15 RCTs (9,111 outpatients) in which interventions were conducted exclusively by pharmacists in 8 studies and in collaboration with physicians, nurses, dietitians, or physical therapists in 7 studies. Pharmacist interventions included medication management, educational interventions, feedback to physicians, measurement of CVD risk factors, or patient-reminder systems. Compared with usual care, pharmacist care was associated with significant reductions for systolic BP (12 studies with 1,894 patients; −6.2 mmHg [95% CI −7.8 to −4.6]); diastolic BP (9 studies with 1,496 patients; −4.5 mmHg [−6.2 to −2.8]); TC (8 studies with 1,280 patients; −15.2 mg/dL [−24.7 to −5.7]); LDL cholesterol (9 studies with 8,084 patients; −11.7 mg/dL [−15.8 to −7.6]); and BMI (5 studies with 751 patients; −0.9 kg/m2 [−1.7 to −0.1]). Pharmacist care was not associated with a significant change in HDL cholesterol (6 studies with 826 patients; 0.2 mg/dL [−1.9 to 2.4]).CONCLUSIONSThis meta-analysis supports pharmacist interventions—alone or in collaboration with other health care professionals—to improve major CVD risk factors among outpatients with diabetes.

Optimizing the use of oral anticoagulant therapy for atrial fibrilation in primary care: a pharmacist-led intervention

“…Our study adds to the evidence base around beneficial effects of pharmacists working in general medical practices care, complementing other studies demonstrating: identification of high risk patients and improved disease management [47]; and increased evidence based prescribing [48]. In a systematic review of 38 studies examining the effectiveness of clinical pharmacists in a primary care, pharmacist input was shown to be favourable in chronic disease management and quality use of medicines [49].…”

Medication adherence in patients after percutaneous coronary intervention due to acute myocardial infarction: From research to clinical implications

“…The necessity to conduct RCTs has been frequently pointed out in relevant literature, especially in the context of distinguishing interventions aimed at primary and secondary prevention of cardiovascular diseases [52]. Patients suffering from cardiovascular diseases, who received assistance from their pharmacist, exhibited a decrease in the systolic and diastolic blood pressure, total cholesterol or -in the context of public health issues -showed a decrease in smoking habits [53]. Of note, one single-center observation showed that telephone contact with patients who were implanted with DES resulted in "near-perfect" DAPT adherence.…”

Primary Care Providers’ Use of Pharmacist Support for Delivery of Pharmacogenetic Testing

“…Previous studies have demonstrated that pharmacists are well suited to provide support, able to create effective relationships with providers and achieve high provider acceptance of pharmacist recommendations [24,25]. Furthermore, pharmacists have successful providers in patient-centered medical homes [26] and have provided care with demonstrated improved patient outcomes [27][28][29].…”
