Pharmacists' Impact on Older Adults Transitioning To and From Patient Care Centers: A Scoping Review.

Objective: Expand upon previous reviews conducted on transitions of care (TOC) services with a focus on pharmacist interventions for older adults specifically transitioning to and from long-term care, acute rehabilitation, residential care facilities, care homes, skilled nursing, or assisted living facilities, collectively termed patient care centers (PCC). Data Sources: A PubMed and Ovid MEDLINE search was conducted including citations between 1974 and July 14, 2022. Bibliographies were also reviewed for additional citations. Methods: Articles included described pharmacist interventions during TOC for patients transitioning to and from PCC, were written in English, and reported outcomes pertaining to TOC services. Of 873 citations reviewed, 22 articles met the inclusion criteria. Results: Most studies were prospective in design with small sample sizes, of limited duration, and with varying interventions and reported outcomes. Most explored the transition from hospital to PCC and included a pharmacist intervention involving the identification of medication errors and discrepancies during the TOC. Few studies reported cost savings or 30- and 60-day reductions in readmission rates or mortality. Conclusions: This scoping review revealed a lack of robust clinical trials to assess the effectiveness of specific interventions performed by pharmacists for patients transitioning to and from PCC. Of the available data, pharmacist involvement within an interprofessional team can be an effective intervention to resolve medication discrepancies, reduce readmissions, and medication-related adverse events. An opportunity exists for future studies to explore ways to improve outcomes during TOC within PCC.

Part Four: Identifying, Managing, and Preventing Adverse Effects of Diabetes Medications.

Background An 81-year-old woman with type 2 diabetes, residing in a long-term care facility, has experienced a fall after medication changes, and a few days of irregular eating. Assessment This patient may be experiencing one or more common potential adverse events related to her diabetes medications. There is a need to create individualized treatment goals in this case. Outcome After a revision of treatment goals for hypertension and diabetes, and adjustments to the medication regimen, there have been no subsequent falls and this patient reports that she feels better. Conclusion As the person with diabetes ages, quality of life should be considered when setting treatment goals. Older people can be more at risk for adverse effects of medications to treat diabetes, so a clinician should be vigilant in the identification, management, and prevention of such adverse events. Inter-professional communication is key to the safe and effective treatment of diabetes.

Clinical applications of pharmacogenomics guided warfarin dosing.

AIM OF THE REVIEW: To assess the state of the literature concerning pharmacogenomic testing in patients requiring vitamin K antagonists, specifically warfarin. METHOD: We conducted a literature search of MEDLINE and International Pharmaceutical Abstracts using the following words: warfarin, pharmacogenetic, and pharmacogenomic. The search results were reviewed by the authors and papers concerning pharmacogenomic testing in warfarin dosing were procured and reviewed. Additionally bibliographies of papers procured were also examined for other studies. The authors focused on clinical trials concerning the use of pharmacogenomic testing in warfarin dosing. RESULTS: Although numerous studies have demonstrated that a significant portion of warfarin dosing variability can be explained by genetic polymorphisms, few prospective studies have been conducted that examine the integration of this information in practical dosing situations. Those that have, have shown that using pharmacogenomic information improves initial dosing estimates and decreases the need for frequent clinic visits and laboratory testing. Data showing a reduction in serious bleeding events is sparse. Cost-effectiveness analyses have generally shown a small but positive effect with pharmacogenomic testing in patients receiving warfarin. CONCLUSION: Several studies have shown that pharmacogenomic testing for warfarin dosing is more accurate that other dosing schemes. Pharmacogenomic testing improves time to a therapeutic international normalized ratio while requiring fewer dosing adjustments. Patients who require higher or lower than usual doses seem to benefit the most. The cost-effectiveness of pharmacogenomic testing as well as preventing of outcomes such as bleeding or thrombosis are not yet elucidated. Pharmacists, especially those in a community setting can play a role in this new technology by educating prescribers and patients concerning pharmacogenomic testing, and by developing and using dosing protocols that incorporate its use.
