Variables associated with adequate INR reversal in warfarin treated patients receiving 4-factor prothrombin complex concentrate.

Dosing of 4-factor prothrombin complex concentrate (4FPCC) in warfarin treated patients generally utilizes international normalized ratio (INR) and patient weight. The recommended maximum dosing for all INR categories is capped at 100 kg weight. Whether this affects INR reversal is unknown. Furthermore, characteristics associated with adequate INR reversal need to be further elucidated. This was a multi-center, retrospective cohort study of 186 patients who received 4FPCC for INR reversal in the setting of warfarin-associated hemorrhage or need for emergent INR reversal. Utilizing multiple regression analysis, we evaluated INR reversal, achievement of hemostasis, and 28-day all-cause mortality. A target INR < 1.4 was achieved in 132 of 186 patients (71%). Factors significantly affecting the odds of achieving target INR were age in years (OR 1.03; 95% CI 1.01-1.06; P = 0.01), weight-based 4FPCC dose (units/kg) (OR 1.04; 95% CI 1.00-1.08; P = 0.03), and 4FPCC dosing normalized to INR (units/kg/INR) (OR 1.18; 95% CI 1.03-1.35; P = 0.02). Hemostasis was achieved in 109 of 148 bleeding patients (73.6%). Blood transfusions were associated with not achieving hemostasis (OR 0.44; 95% CI 0.21-0.93; P = 0.03). All-cause 28-day mortality was 21.5% and was associated with intracranial hemorrhage (OR 2.83; 95% CI 1.38-5.8; P = 0.01). Adequate INR reversal was associated with age, weight-based 4FPCC dose, and dosing normalized to INR (units/kg/INR). Future studies should evaluate the appropriateness of current INR targets for warfarin reversal and alternative 4FPCC dosing strategies such as utilizing a 4FPCC dosing ratio of units/kg/INR.

Turmeric-Associated Drug-Induced Liver Injury.

Turmeric is a common herbal supplement used for its possible anti-inflammatory and other properties. It is marketed as safe with few reports of major adverse effects directly related to oral supplementation. We report a case of turmeric supplement-induced liver injury in a 49-year-old woman admitted with elevated aspartate aminotransferase and alanine aminotransferase with no history of liver disease or alcohol use disorder. Thus, this case re-emphasizes the importance of evaluating herbal and dietary supplements as potential drug-induced liver injury causes.

High-dose versus low-dose 4-factor prothrombin complex concentrate for factor Xa inhibitor reversal in intracranial hemorrhage.

BACKGROUND & PURPOSE: 4-factor prothrombin complex concentrate (4FPCC) is used off-label for factor Xa (FXa) inhibitor-associated intracranial hemorrhage (ICH). Guideline recommendations provide various 4FPCC dosing regimens for FXa inhibitor reversal in this setting. We evaluated 4FPCC weight-based dosing and outcomes in FXa inhibitor-associated ICH. METHODS: We conducted a multi-center, retrospective, cohort study of ICH patients between July 2017 and February 2020. Patients were greater than 18 years of age, received 4FPCC, and were taking apixaban, rivaroxaban, or edoxaban. Patients were separated into high- (≥35 units/kg) or low-dose (<35 units/kg) 4FPCC groups. The primary outcome was hemostasis achievement. Secondary outcomes included in-hospital mortality, intensive care unit and hospital length of stay, discharge disposition, and thrombotic events. Outcomes were evaluated with binary logistic regression. RESULTS: Of 390 patients identified, 89 were included with 74 and 15 in the high- vs low-dose groups, respectively. Mean (SD) age was 76.6 (±10.8) years. Most were taking a FXa inhibitor for atrial fibrillation (76.4%) and apixaban was the most common FXa inhibitor (65.2%). Hemostasis achievement was greater in the high- vs low-dose group (89.2% vs 46.7%; OR 11.2; 95% CI 2.4-52.6, P = 0.002). Thrombotic events were 8.2% and 6.7% in the high vs low-dose groups, respectively (OR 0.8; 95% CI 0.08-8.2, P = 0.87). No statistically significant differences were found in secondary outcomes. CONCLUSION: In patients with FXa inhibitor-associated ICH, high-dose 4FPCC was associated with increased odds of hemostasis achievement. There was no difference in thrombotic events.

COVID-19 preparedness: Clinical pharmacy services remote staffing in a quaternary, level I trauma and comprehensive stroke center.

PURPOSE: The rapid spread of the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19), has strained the resources of healthcare systems around the world. In accordance with recommendations from the World Health Organization, Centers for Disease Control and Prevention, and US Department of Defense, Intermountain Medical Center (IMED) in Murray, UT, has developed a plan to provide remote clinical pharmacy services to protect the health of pharmacy caregivers while maintaining appropriate clinical pharmacy coverage to optimally care for patients. SUMMARY: The utilization of telemedicine technology permits clinical pharmacists to readily communicate with nurses, physicians, other caregivers, and patients. We have identified strategies to allow clinical pharmacists to continue to participate in daily rounds, provide consultations under collaborative practice agreements, verify medication orders, collect medication histories, provide antimicrobial stewardship, and deliver medication education to patients from off-site locations. The pharmacy department at IMED proactively tested telemedicine technologies, defined the roles of clinical pharmacists, and identified communication strategies prior to a rapid rise in COVID-19 cases in the state of Utah. CONCLUSION: The proactive measures described can help ensure that pharmacy caregivers have appropriate remote access and are capable of confidently using the resources. These steps allow for optimal care of hospitalized patients and promote social distancing, which may have the added benefit of decreasing the spread of SARS-CoV-2 among patients and caregivers.

Improving end-of-rotation transitions of care among ICU patients.

BACKGROUND: Hospitalised patients whose inpatient teams rotate off service experience increased mortality related to end-of-rotation care transitions, yet standardised handoff practices are lacking. OBJECTIVE: Develop and implement a multidisciplinary patient-centred handoff intervention to improve outcomes for patients who are critically ill during end-of-rotation transitions. DESIGN, SETTING AND PARTICIPANTS: Single-centre, controlled pilot study of medical intensive care unit (ICU) patients whose resident team was undergoing end-of-rotation transition at a university hospital from June 2017 to February 2018. INTERVENTION: A 4-item intervention was implemented over two study periods. Intervention 1 included: (1) in-person bedside handoff between teams rotating off and on service, (2) handoff checklist, (3) nursing involvement in handoff, and (4) 30 min education session. Intervention 2 included the additional option to conduct bedside handoff via videoconferencing. MAIN OUTCOME MEASURES: Implementation was measured by repeated clinician surveys and direct observation. Patient outcomes included length of stay (LOS; ICU and hospital) and mortality (ICU, hospital and 30 days). Clinician perceptions were modelled over time using per cent positive responses in logistic regression. Patient outcomes were compared with matched control 'transition' patients from 1 year prior to implementation of the intervention. RESULTS: Among 270 transition patients, 46.3% were female with a mean age of 55.9 years. Mechanical ventilation (64.1%) and in-hospital death (27.6%) rates were prevalent. Despite high implementation rates-handoff participation (93.8%), checklist utilisation (75.0%), videoconferencing (62.5%), nursing involvement (75.0%)-the intervention did not significantly improve LOS or mortality. Multidisciplinary survey data revealed significant improvement in acceptability by nursing staff, while satisfaction significantly declined for resident physicians. CONCLUSIONS: In this controlled pilot study, a structured ICU end-of-rotation care transition strategy was feasible to implement with high fidelity. While mortality and LOS were not affected in a pilot study with limited power, the pragmatic strategy of this intervention holds promise for future trials.
