Time and motion study of pharmacist prescribing of oral hormonal contraceptives in Oregon community pharmacies.

OBJECTIVES: The aim of this time and motion study was to evaluate the procedural time and steps of performing an oral hormonal contraceptive pharmacist prescribing service in an Oregon community pharmacy. METHODS: A standardized patient seeking oral hormonal contraception visited 13 community pharmacies throughout February 2018 in the tri-county Portland, Oregon, metropolitan area for pharmacist-prescribed hormonal contraception services for a total of 26 patient encounters. An observer was present at each encounter to record the time for each step and the total encounter time. Each pharmacist was asked to perform assessment procedures and prescribing for each of 2 standardized patient presentations: in cohort 1 (n = 13), the pharmacist's assessment resulted in a hormonal contraception prescription written; in cohort 2 (n = 13), pharmacist's assessment detected contraindications and resulted in a medical referral to another health care prescriber. RESULTS: The average total patient time from arrival at the pharmacy to the generation of either a written prescription for hormonal contraception or referral to another health care provider was 17.9 and 14.1 minutes, respectively. Without accounting for documentation or dispensing the prescription, the average total pharmacist time to perform the service and issue a prescription, or refer the patient, was 7.8 and 5.4 minutes, respectively. CONCLUSION: The results indicate that the pharmacist prescribing service for oral hormonal contraception requires a modest amount of pharmacist time. Incorporation of practice into regular workflow appears to have an impact similar to other clinical services, such as immunizations and point-of-care testing. The patient time spent with the pharmacist was similar to other health care provider visits.

Assessing pharmacologic and nonpharmacologic risks in candidates for kidney transplantation.

PURPOSE: Pharmacotherapy concerns and other factors with a bearing on patient selection for kidney transplantation are discussed. SUMMARY: The process of selecting appropriate candidates for kidney transplantation involves multidisciplinary assessment to evaluate a patient's mental, social, physical, financial, and medical readiness for successful surgery and good posttransplantation outcomes. Transplantation pharmacists can play important roles in the recognition and stratification of pharmacologic and nonpharmacologic risks in prospective kidney transplant recipients and the identification of issues that require a mitigation strategy. Key pharmacotherapy-related issues and considerations during the risk assessment process include (1) anticoagulation concerns, (2) cytochrome P-450 isoenzyme-mediated drug interactions, (3) mental health-related medication use, (4) chronic pain-related medication use, (5) medication allergies, (6) use of hormonal contraception and replacement therapy, (7) prior or current use of immunosuppressants, (8) issues with drug absorption, (9) alcohol use, (10) tobacco use, (11) active use of illicit substances, and (12) use of herbal supplements. Important areas of nonpharmacologic risk include vaccine delivery, infection prophylaxis and treatment, and socially related factors such as nonadherent behavior, communication barriers, and financial, insurance, or transportation challenges that can compromise posttransplantation outcomes. CONCLUSION: Consensus opinions of practitioners in transplantation pharmacy regarding the pharmacologic and nonpharmacologic factors that should be considered in assessing candidates for kidney transplantation are presented.

Pharmacogenomic considerations in the treatment of the pediatric cardiomyopathy called Barth syndrome.

Barth syndrome (BTHS) is a genetic, X-linked, rare but often fatal, pediatric skeletal- and cardiomyopathy occurring due to mutations in the tafazzin gene (TAZ). TAZ encodes a transacylase involved in phospholipid biosynthesis, also called tafazzin, which is responsible for remodeling the inner mitochondrial membrane phospholipid, cardiolipin (CL). Tafazzin mutations lead to compositional alterations in CL molecular species, causing extensive mitochondrial aberrations and ultrastructural muscle damage. There are no specific treatments or cure for BTHS. Current therapy is largely palliative and aimed at treatment of organ-specific complications during disease progression. Polypharmacy frequently occurs during treatment and may lead to severe adverse events. Adverse reactions may originate from exogenous factors such as the inadvertent co-administration of contraindicated drugs. Theoretically, endogenous factors such as polymorphic variations in genes encoding drug metabolizing enzymes may also precipitate fatal toxicity. Investigation of the consequences of pharmacogenomic variations on BTHS therapy is lacking. To our knowledge, this review presents the first examination of the possible sources of pharmacogenomic variations that may affect BTHS therapy. We also explore BTHSspecific patents for possible treatment options. The patents discussed suggest innovative strategies for treatment, including feeding linoleic acid to patients to overcome compositional CL deficiency; or the use of 2S,4R ketoconazole formulations to augment CL levels; or the delivery of mitochondrial stabilizing cargo. Future research directions are also discussed.
