Pharmacogenetic testing (PGT) is increasingly being used as a tool to guide clinical decisions. This article describes the development of an outpatient, pharmacist-led, pharmacogenetics consult clinic within internal medicine, its workflow, and early results, along with successes and challenges. A pharmacogenetics-trained pharmacist encouraged primary care physicians (PCPs) to refer patients who were experiencing side effects/ineffectiveness from certain antidepressants, opioids, and/or proton pump inhibitors. In clinic, the pharmacist confirmed the need for and ordered CYP2C19 and/or CYP2D6 testing, provided evidence-based pharmacogenetic recommendations to PCPs, and educated PCPs and patients on the results. Operational and clinical metrics were analyzed. In two years, 91 referred patients were seen in clinic (mean age 57, 67% women, 91% European-American). Of patients who received PGT, 77% had at least one CYP2C19 and/or CYP2D6 phenotype that would make conventional prescribing unfavorable. Recommendations suggested that physicians change a medication/dose for 59% of patients; excluding two patients lost to follow-up, 87% of recommendations were accepted. Challenges included PGT reimbursement and referral maintenance. High frequency of actionable results suggests physician education on who to refer was successful and illustrates the potential to reduce trial-and-error prescribing. High recommendation acceptance rate demonstrates the pharmacist’s effectiveness in providing genotype-guided recommendations, emphasizing a successful pharmacist–physician collaboration.

Purpose The safety and efficacy of dual antiplatelet therapy (DAPT) with aspirin and clopidogrel in the setting of secondary stroke prevention are reviewed. Summary Antiplatelet therapy has been shown to reduce the risk of numerous vascular events, especially in the setting of secondary prevention. DAPT with aspirin and another antiplatelet agent such as clopidogrel, prasugrel, or ticagrelor has become the main stay of acute coronary syndrome (ACS) management. The underlying pathophysiologies of ACS, ischemic stroke, and transient ischemic attack (TIA) are similar. In the setting of ACS, DAPT has clearly been shown to improve outcomes over single antiplatelet therapy for up to 12 months after the ischemic event. However, the role for DAPT in the setting of ischemic stroke and TIA is less clear. The MATCH, CHARISMA, and SPS3 studies demonstrated that DAPT was associated with increased bleeding compared with single antiplatelet therapy without an appreciable reduction in ischemic events. Early initiation of DAPT proved beneficial in reducing future ischemic events in the FASTER and CHANCE trials; however, these trials did not provide enough evidence to recommend the routine use of DAPT in secondary stroke prevention, and current guidelines recommend against such therapy. DAPT with aspirin and clopidogrel appears to be effective only for patients with minor stroke or TIA when started within 24 hours of the ischemic event and continued for a maximum of 21 days. Conclusion Currently available evidence does not substantiate the widespread use of long-term aspirin with clopidogrel for the secondary prevention of ischemic stroke or TIA.

Ambulatory blood pressure monitoring (ABPM) is increasingly recommended for confirming hypertension diagnosis and ongoing hypertension monitoring. However, reimbursement in the United States is variable and low compared with other advanced health care systems. We examined the reimbursement of ABPM and factors associated with successful reimbursement. A retrospective analysis of IBM MarketScan^® commercial claims database was conducted for patients ≥18 years with ≥1 ABPM claim from January 2012 to December 2016. The date of first the ABPM claim was used as the index date. Per‐beneficiary ABPM episode reimbursements were calculated by aggregating all ABPM‐related reimbursements within a 30‐day post‐index window, considered as an ABPM episode. Multivariable logistic regression was used to identify predictors of successful reimbursement. Of 20 875 beneficiaries with ABPM claims, 16 920 (81.0%) were reimbursed. The median reimbursement per beneficiary for an ABPM episode was $89 (Inter Quartile Range [IQR], $62, $132), driven primarily by reimbursement for the full procedure (median, $86; IQR, $66, $110). Comparing benefit plan types, consumer‐directed health plans provided the highest median reimbursement ($96; IQR, $61, $175). Successful reimbursement was associated with female patient sex (adjusted OR [aOR], 1.20; 95% CI, 1.11‐1.28), having a health maintenance organization (aOR 2.11; 95% CI, 1.82‐2.43) or point of service (aOR 2.08; 95% CI, 1.74‐2.49) as benefit plan types, claim filing by a specialist (aOR 1.26; 95% CI, 1.14‐1.40) and services provided at an outpatient hospital (aOR 1.17; 95% CI, 1.01‐1.35). Among commercially insured Americans, our data suggest significant variability in successful reimbursement. Accordingly, more uniform criteria for ABPM reimbursement may facilitate greater use of guideline‐recommended monitoring.
