Importance: The National Action Plan for Adverse Drug Event (ADE) Prevention identified 3 high-priority, high-risk drug classes as targets for reducing the risk of drug-related injuries: anticoagulants, diabetes agents, and opioids.

Objective: To determine whether a multifaceted clinical pharmacist intervention improves medication safety for patients who are discharged from the hospital and prescribed medications within 1 or more of these high-risk drug classes.

Design, Setting, And Participants: This randomized clinical trial was conducted at a large multidisciplinary group practice in Massachusetts and included patients 50 years or older who were discharged from the hospital and prescribed at least 1 high-risk medication.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for the coronavirus disease (COVID-19) pandemic, has challenged practitioners with complex clinical scenarios as well as conflicting and scarce data to support treatment strategies. The pandemic has also placed strains on institutions due to drug shortages, alterations in medication use processes, economic losses, and staff exposure to the virus. This article provides pharmacist-led suggestions and strategies to various case questions, describing some of the challenges faced by practitioners at an urban teaching hospital during the COVID-19 pandemic.

The American College of Chest Physicians guidelines recommend unfractionated heparin (UFH), low molecular weight heparins (LMWHs) or fondaparinux for prevention of venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE), in medically-ill patients. Direct oral anticoagulants (DOACs) have been evaluated relative to enoxaparin for VTE prophylaxis though head-to-head comparisons of these agents are lacking. Therefore, we conducted a mixed treatment comparisons meta-analysis to evaluate the safety and efficacy of established treatments and DOACs for VTE prophylaxis in medically-ill patients.

Objectives: Older adults are often transferred from hospitals to skilled nursing facilities (SNFs) for post-acute care. Patients may be at risk for adverse outcomes after SNF discharges, but little research has focused on this period.

Design: Assessment of the feasibility of a transitional care intervention based on a combination of manual information transmission and health information technology to provide automated alert messages to primary care physicians and staff; pre-post analysis to assess potential impact.

Objective: Little is known about how to best taper antipsychotics used in patients with dementia. To address this gap, we reviewed published antipsychotic discontinuation trials to summarize what is known about tapering strategies for antipsychotics used with older adults with dementia. We further developed pharmacokinetic-based gradual dose reduction (GDR) protocols based on antipsychotic half-lives.

Objectives: To evaluate the effectiveness of efforts to translate and disseminate evidence-based guidelines about atypical antipsychotic use to nursing homes (NHs).

Design: Three-arm, cluster randomized trial.

Setting: NHs.

Purpose: The needs of complex patients with chronic conditions can be unpredictable and can strain resources. Exploring how tasks vary for different patients, particularly those with complex needs, can yield insights about designing better processes in healthcare. The purpose of this paper is to explore the tasks required to manage complex patients in an anticoagulation therapy context.

The American College of Clinical Pharmacy (ACCP) Research Affairs Committee published a commentary in 2013 on training clinical pharmacy scientists in the context of changes in economic, professional, political, and research environments. The commentary centered on the opportunities for pharmacists in clinical/translational research including strategies for ACCP, colleges of pharmacy, and the profession to increase the number and impact of clinical pharmacy scientists. A postdoctoral fellowship is cited as a current training pathway, capable of producing independent and productive pharmacy researchers.

Objectives: To describe the current extent and type of pharmaceutical marketing in nursing homes (NHs) in one state and to provide preliminary evidence for the potential influence of pharmaceutical marketing on the use of atypical antipsychotics in NHs.

Design: Nested mixed-methods, cross-sectional study of NHs in a cluster randomized trial.

Setting: Forty-one NHs in Connecticut.

Purpose: Target-specific oral anticoagulants (apixaban, rivaroxaban, and dabigatran) are widely available for the treatment of venous thromboembolism (VTE). Although analyses comparing these agents to placebo or warfarin exist, direct comparisons of these agents for extended VTE treatment have not been conducted. Therefore, this network meta-analysis aimed to evaluate the efficacy and tolerability of VKA and target-specific oral anticoagulants for extended VTE treatment using a mixed-treatment comparison, meta-analytic approach.

Background: The relationship between psychiatric consultation and antipsychotic prescribing in nursing homes (NH) is unknown.

Objective: To identify the association between psychiatric consultant groups and NH-level antipsychotic prescribing after adjustment for resident case-mix and facility characteristics.

Research Design And Subjects: Nested cross-sectional study of 60 NHs in a cluster randomized trial.

Background: The current guidelines recommend various antiplatelet agents used alone or in combination for secondary prevention of noncardioembolic stroke.

Objective: The purpose of this study was to conduct a mixed treatment comparison meta-analysis to determine which antiplatelet or combination of antiplatelet agents is most efficacious and tolerable in patients with prior stroke.

Methods: A comprehensive literature search was conducted in MEDLINE (1945 through March 2012), EMBASE (1974 through March 2012), and the Cochrane Controlled Trials Registry (1975 through April 2012) to identify randomized trials evaluating the role of various antiplatelet agents and combinations for the secondary prevention of stroke.

Objectives: To characterize adverse drug events (ADEs) occurring within the high-risk 45-day period after hospitalization in older adults.

Design: Clinical pharmacists reviewed the ambulatory records of 1,000 consecutive discharges.

Setting: A large multispecialty group practice closely aligned with a Massachusetts-based health plan.

Background/objectives: Antipsychotic use is common in US nursing homes, despite evidence of increased risk of morbidity and mortality, and limited efficacy in older adults with dementia. Knowledge, attitudes, and beliefs regarding antipsychotic use among nursing home staff are unclear. The study aim was to describe nursing home leadership and direct care staff members' knowledge of antipsychotic risks, beliefs and attitudes about the effectiveness of antipsychotics and nonpharmacologic management of dementia-related behaviors, and perceived need for evidence-based training about antipsychotic medication safety.

Purpose: Observational studies describe high rates of errors in home oral chemotherapy use in children. In hospitals, proactive risk assessment methods help front-line health care workers develop error prevention strategies. Our objective was to engage parents of children with cancer in a multisite study using proactive risk assessment methods to identify how errors occur at home and propose risk reduction strategies.

Heparin-induced thrombocytopenia is a rare and serious reaction to unfractionated heparin and low-molecular-weight heparins in children. Quick recognition, discontinuation of heparin, and subsequent treatment with an alternative anticoagulant are essential steps to prevent serious complications such as thrombus and limb amputation. The purpose of this review is to describe the clinical features of heparin-induced thrombocytopenia in children and to summarize the data available for its management.

Background: Little attention has been focused on the safety of medications administered to treat non illnesses in nursing home residents with dementia. It is unclear whether this population is at increased risk of adverse drug events.

Objectives: To test the hypotheses that in nursing home residents with dementia prescribed warfarin have less time in therapeutic range and a higher incidence of nonpreventable and preventable adverse warfarin events compared to nursing home residents without dementia after controlling for facility and patient characteristics.
