Proportion of Patients on Warfarin Therapy Who Are Eligible for Conversion to a Direct Oral Anticoagulant in the Setting of COVID-19.

BACKGROUND: Warfarin, a commonly prescribed anticoagulant, requires frequent lab monitoring. Lab monitoring puts patients at risk of COVID-19 exposure and diverts medical resources away from health care systems. Direct oral anticoagulants (DOACs) do not require routine therapeutic monitoring and are indicated first line for nonvalvular atrial fibrillation (NVAF) stroke prevention and venous thromboembolism (VTE) prevention/treatment. OBJECTIVE: The purpose of the study was to determine the proportion of patients who qualify for DOACs and assess for predictors of qualification. METHODS: This cross-sectional study investigated patients on warfarin managed by Michigan Medicine Anticoagulation Service. Direct oral anticoagulant eligibility criteria were established using apixaban, dabigatran, and rivaroxaban package inserts. Patient eligibility was determined through chart review. The primary outcome was the proportion of patients who qualify for DOACs based on clinical factors. Predictors of DOAC qualification were assessed. RESULTS: This study included 3205 patients and found 51.8% (n = 1661) of patients qualified for DOACs. Qualifying patients were older (71.9 vs 59.4 years, P < 0.0001) with a higher CHA2DS2 VASc (3.7 vs 3.4, P < 0.0007). The primary disqualifying factor was extreme weight, high and low. Accounting for a patient's sex and referral source, age > 65 (odds ratio [OR] = 1.9, P < 0.0001) and NVAF indication (OR = 5.6, P < 0.0001) were significant predictors for DOAC qualification. CONCLUSION AND RELEVANCE: Approximately 52% of patients on warfarin were eligible for DOACs. This presents an opportunity to reduce patient exposure to health care settings and health care utilization in the setting of COVID-19. Increased costs of DOACs need to be assessed.

Standards-Based Clinical Decision Support Platform to Manage Patients Who Meet Guideline-Based Criteria for Genetic Evaluation of Familial Cancer.

PURPOSE: The ubiquitous adoption of electronic health records (EHRs) with family health history (FHH) data provides opportunities for tailoring cancer screening strategies to individuals. We aimed to enable a standards-based clinical decision support (CDS) platform for identifying and managing patients who meet guidelines for genetic evaluation of hereditary cancer. METHODS: The CDS platform (www.opencds.org) was used to implement algorithms based on the 2018 National Comprehensive Cancer Network guidelines for genetic evaluation of hereditary breast/ovarian and colorectal cancer. The platform was designed to be interfaced with different EHR systems via the Health Level Seven International Fast Healthcare Interoperability Resources standard. The platform was integrated with the Epic EHR and evaluated in a pilot study at an academic health care system. RESULTS: The CDS platform was executed against a target population of 143,012 patients; 5,245 (3.7%) met criteria for genetic evaluation based on the FHH recorded in the EHR. In a clinical pilot study, genetic counselors attempted to reach out to 71 of the patients. Of those patients, 25 (35%) scheduled an appointment, 10 (14%) declined, 2 (3%) did not need genetic counseling, 7 (10%) said they would consider it in the future, and 27 (38%) were unreachable. To date, 13 (52%) of the scheduled patients completed visits, and 2 (15%) of those were found to have pathogenic variants in cancer predisposition genes. CONCLUSION: A standards-based CDS platform integrated with EHR systems is a promising population-based approach to identify patients who are appropriate candidates for genetic evaluation of hereditary cancers.

Potential Deaths Averted and Serious Adverse Events Incurred From Adoption of the SPRINT (Systolic Blood Pressure Intervention Trial) Intensive Blood Pressure Regimen in the United States: Projections From NHANES (National Health and Nutrition Examination Survey).

BACKGROUND: SPRINT (Systolic Blood Pressure Intervention Trial) demonstrated a 27% reduction in all-cause mortality with a systolic blood pressure (SBP) goal of <120 versus <140 mm Hg among US adults at high cardiovascular disease risk but without diabetes mellitus, stroke, or heart failure. To quantify the potential benefits and risks of SPRINT intensive goal implementation, we estimated the deaths prevented and excess serious adverse events incurred if the SPRINT intensive SBP treatment goal were implemented in all eligible US adults. METHODS: SPRINT eligibility criteria were applied to the 1999 to 2006 National Health and Nutrition Examination Survey and linked with the National Death Index through December 2011. SPRINT eligibility included age ≥50 years, SBP of 130 to 180 mm Hg (depending on the number of antihypertensive medications being taken), and high cardiovascular disease risk. Exclusion criteria were diabetes mellitus, history of stroke, >1 g proteinuria, heart failure, estimated glomerular filtration rate <20 mL·min-1·1.73 m-2, or dialysis. Annual mortality rates were calculated by dividing the Kaplan-Meier 5-year mortality by 5. Hazard ratios for all-cause mortality and heart failure and absolute risks for serious adverse events in SPRINT were used to estimate the number of potential deaths and heart failure cases prevented and serious adverse events incurred with intensive SBP treatment. RESULTS: The mean age was 68.6 years, and 83.2% and 7.4% were non-Hispanic white and non-Hispanic black, respectively. The annual mortality rate was 2.20% (95% confidence interval [CI], 1.91-2.48), and intensive SBP treatment was projected to prevent ≈107 500 deaths per year (95% CI, 93 300-121 200) and give rise to 56 100 (95% CI, 50 800-61 400) episodes of hypotension, 34 400 (95% CI, 31 200-37 600) episodes of syncope, 43 400 (95% CI, 39 400-47 500) serious electrolyte disorders, and 88 700 (95% CI, 80 400-97 000) cases of acute kidney injury per year. The analysis-of-extremes approach indicated that the range of estimated lower- and upper-bound number of deaths prevented per year with intensive SBP control was 34 600 to 179 600. Intensive SBP control was projected to prevent 46 100 (95% CI, 41 800-50 400) cases of heart failure annually. CONCLUSIONS: If fully implemented in eligible US adults, intensive SBP treatment could prevent ≈107 500 deaths per year. A consequence of this treatment strategy, however, could be an increase in serious adverse events.

MF101, a selective estrogen receptor beta modulator for the treatment of menopausal hot flushes: a phase II clinical trial.

OBJECTIVE: To determine the optimal dose, safety, and efficacy of an estrogen receptor beta selective Chinese herbal extract, menopausal formula 101 (MF101), for treating hot flushes. METHODS: A randomized, blinded trial in 217 postmenopausal women with hot flushes randomized to 5 or 10 g/day of MF101 or placebo for 12 weeks. RESULTS: The effects of 5 g/day of MF101 did not differ from those of placebo. After 12 weeks, the mean percent decrease in frequency of hot flushes in the 10 g/day group was 12.9% greater than that in the placebo group (P = 0.15), the median percent decrease was 11.7% greater than that in the placebo group (P = 0.05), and the proportion of women with at least a 50% reduction in hot flushes was 16.2% greater than that in the placebo group (P = 0.03). CONCLUSIONS: Treatment with 10 g/day of MF101 reduces the frequency of hot flushes. Trials with higher doses are planned.
