Remission and Treatment Augmentation of Depression in the United States.

Objective: To determine the proportion of adults treated for depression in the US who achieve remission and, among those not achieving remission, the proportion receiving augmentation treatment.Methods: Using data from the US National Health and Nutrition Examination Survey (NHANES) for years 2013-2014, 2015-2016, and 2017-2018, we identified 869 adults who reported using antidepressant medications for depression for at least 3 months. This sample was partitioned into remitted (score < 5) and non-remitted (score ≥ 5) respondents based on 9-item Patient Health Questionnaire (PHQ-9) score-a questionnaire based on the DSM-IV criteria for major depressive disorder. Among the non-remitted group, the proportion receiving antidepressant augmentation with another antidepressant medication of a different class or other medications was also assessed.Results: An estimated 43.5% of adults receiving antidepressant medications for depression were in remission when assessed. Among those not in remission, 28.1% were using augmentation treatment, which in most cases was another antidepressant medication from a different class. As compared to depressed adults without any mental health contact in the past year, those with such contact had significantly higher odds of using augmentation treatment (adjusted odds ratio = 2.72; 95% CI, 1.56-4.76; P = .001).Conclusions: The low percentage of US adults treated with antidepressants for depression that achieves remission represents a missed clinical and public health opportunity to optimize depression treatment. Closer monitoring of symptoms through measurement-based care and setting symptom remission as a goal can help improve outcomes for adults with depression.

Determinants of Influenza Vaccine Uptake in Patients With Cardiovascular Disease and Strategies for Improvement.

Cardiovascular disease (CVD) is the leading cause of death and disability worldwide. Influenza infection is associated with an increased risk of cardiovascular events (myocardial infarction, stroke, and heart failure exacerbation) and mortality, and all-cause mortality in patients with CVD. Infection with influenza leads to a systemic inflammatory and thrombogenic response in the host body, which further causes destabilization of atherosclerotic plaques. Influenza vaccination has been shown to be protective against cardiovascular and cerebrovascular events in several observational and prospective studies of at-risk populations. Hence, many international guidelines recommend influenza vaccination for adults of all ages, especially for individuals with high-risk conditions such as CVD. Despite these long-standing recommendations, influenza vaccine uptake among US adults with CVD remains suboptimal. Specifically, vaccination uptake is strikingly low among patients aged <65 years, non-Hispanic Black individuals, those without health insurance, and those with diminished access to healthcare services. Behavioral factors such as perceived vaccine efficacy, vaccine safety, and attitudes towards vaccination play an important role in vaccine acceptance at the individual and community levels. With the ongoing COVID-19 pandemic, there is a potential threat of a concurrent epidemic with influenza. This would be devastating for vulnerable populations such as adults with CVD, further stressing the need for ensuring adequate influenza vaccination coverage. In this review, we describe a variety of strategies to improve the uptake of influenza vaccination in patients with CVD through improved understanding of key sociodemographic determinants and behaviors that are associated with vaccination, or the lack thereof. We further discuss the potential use of relevant strategies for COVID-19 vaccine uptake among those with CVD.

Trends in Use of Cardioprotective Medication in Peripheral Artery Disease: A Nationwide Study.

Background Guideline-based cardioprotective medical therapy is intended to reduce the burden of adverse cardiovascular and limb outcomes in patients with peripheral artery disease (PAD). However, contemporary data describing trends in use of medication remains limited. The present study, therefore, aims to investigate changes in use of cardioprotective medication in PAD. Methods and Results By using Danish national healthcare registries, we identified all patients with first-time diagnosis of PAD (1997-2016) and classified them into two groups: (1) PAD+ that includes all patients with PAD with a history of cardiovascular disease, ie, myocardial infarction, atrial fibrillation, and stroke (n=162 627); and (2) PAD (n=87 935) that comprise patients without a history of cardiovascular disease. We determined the use of medication in the first 12 months after the incident diagnosis of PAD and estimated age standardized 1-year mortality rates. Our results showed increase in use of cardioprotective medication throughout the study period in both groups. However, PAD+ had a higher use of medication (acetylsalicylic acid, 3.5%-48.4%; Clopidogrel, 0%-17.6%; vitamin K antagonists, 0.9%-7.8%; new oral anticoagulants, 0.0%-10.1%; Statins, 1.9%-58.1%; angiotensin-converting enzyme inhibitors, 1.2%-20.6%), compared with PAD (acetylsalicylic acid, 2.9%-54.4%; Clopidogrel, 0%-11.9%; vitamin K antagonists, 0.9%-2.4%; new oral anticoagulants, 0.0%-3.4%; Statins, 1.5%-56.9%; angiotensin-converting enzyme, 0.9%-17.2%), respectively. Furthermore, 1-year mortality rates in PAD declined with increased use of medications during study. Conclusions In this nationwide study, use of cardioprotective medication increased considerably with time, but compared to patients with other atherosclerotic diseases, there remains an underuse of guideline-based medical therapy in patients with PAD.

Patterns of cost-related medication underuse among Canadian adults with cancer: a cross-sectional study using survey data.

BACKGROUND: Cost-related medication underuse (CRMU) has been reported within the general population in Canada. In this study, we assessed patterns of CRMU among Canadian adults with cancer. METHODS: This is a cross-sectional study using survey data. We accessed data sets from the 2015/16 Canadian Community Health Survey (CCHS) and reviewed the records of adults (≥ 18 yr) with a history of cancer who were prescribed medication in the previous 12 months. We collected information about sociodemographic features, health behaviours and CRMU, and conducted a multivariable logistic regression analysis for factors associated with CRMU. RESULTS: A total of 8581 participants were eligible for the current study. In the weighted multivariable logistic regression analysis, the following factors were associated with CRMU: younger age (odds ratio [OR] 2.55, 95% confidence interval [CI] 1.79-3.63), female sex (male sex v. female sex OR 0.62, 95% CI 0.44-0.88), Indigenous racial background (Indigenous v. White OR 2.37, 95% CI 1.49- 3.77), unmarried status (OR 1.59, 95% CI 1.09-2.30), poor self-perceived health (excellent v. poor self-perceived health OR 0.36, 95% CI 0.17-0.77), lower annual income (< $20 000 v. income ≥ $80 000 OR 3.08, 95% CI 1.75-5.41) and lack of insurance for prescription medications (OR 2.49, 95% CI 1.77-3.50). INTERPRETATION: The toll of CRMU among adults seems to be unequally carried by women, racial minorities, and younger (< 65 yr) and uninsured patients with cancer. Discussion about a national pharmacare program for people without private insurance is needed.

Factors Associated With Access to and Timing of Coronavirus Testing Among US Adults After Onset of Febrile Illness.

Importance: Active SARS-CoV-2 (coronavirus) transmission continues in the US. It is unclear whether better access to coronavirus testing and more consistent use of testing could substantially reduce transmission. Objective: To describe coronavirus testing in persons with new onset of febrile illness and analyze whether there are changes over time and differences by race and ethnicity. Design, Setting, and Participants: This cohort study used data from the COVID-19 Citizen Science Study, launched in March 2020, which recruited participants via press release, word-of-mouth, and partner organizations. Participants completed daily surveys about COVID-19 symptoms and weekly surveys about coronavirus testing. All adults (aged at least 18 years) with a smartphone were eligible to join. For this analysis, US participants with new onset of febrile illness from April 2020 to October 2020 were included. Data analysis was performed from November 2020 to March 2021. Main Outcomes and Measures: Receipt of a coronavirus test result within 7 days of febrile illness onset. Results: Of the 2679 participants included in this analysis, the mean (SD) age was 46.3 (13.4) years, 1983 were female (74%), 2017 were college educated (75%), and a total of 3865 distinct new febrile illness episodes were reported (300 episodes [7.8%] from Hispanic participants, 71 episodes [1.8%] from Black participants, and 3494 episodes [90.4%] from not Black, not Hispanic participants) between April 2 and October 23, 2020. In weekly surveys delivered during the 14 days after fever onset, 12% overall (753 participants) indicated receipt of a test result. Using serial survey responses and parametric time-to-event modeling, it was estimated that by 7 days after onset of febrile illness, a total of 20.5% (95% CI, 19.1%-22.0%) had received a test result. This proportion increased from 9.8% (95% CI, 7.5%-12.0%) early in the epidemic to 24.1% (95% CI, 21.5%-26.7%) at the end of July, but testing rates did not substantially improve since then, increasing to 25.9% (95% CI; 21.6%-30.3%) in late October at the start of the winter surge. Black participants reported receiving a test result about half as often as others (7% [7 of 103] of survey responses vs 12% [53 of 461] for Hispanic vs 13% [693 of 5516] for not Black, not Hispanic; P = .03). This association was not statistically significant in adjusted time-to-event models (hazard ratio = 0.59 vs not Black, not Hispanic participants; 95% CI, 0.26-1.34). Conclusions and Relevance: Systematic underuse of coronavirus testing was observed in this cohort study through late October 2020, at the beginning of the winter COVID-19 surge, which may have contributed to preventable coronavirus transmission.

Molecular Biomarker and Programmed Death-Ligand 1 Expression Testing in Patients With Advanced Stage Non-small Cell Lung Cancer Across North Carolina Community Hospitals.

BACKGROUND: Precision medicine in advanced non-small cell lung cancer (NSCLC) requires molecular biomarker testing in patients with nonsquamous and select patients with squamous histologies, and programmed death-ligand 1 (PD-L1) testing in both. RESEARCH QUESTION: What are rates of molecular and PD-L1 biomarker testing in patients with advanced NSCLC in community practices, and do rates vary by sociodemographic factors? What is the prevalence of molecular biomarker mutations and PD-L1 expression levels? STUDY DESIGN AND METHODS: From 389 stage IV NSCLC pathology reports obtained through the University of North Carolina Lineberger Comprehensive Cancer Center's Rapid Case Ascertainment Program from 38 community hospitals across North Carolina, we abstracted demographics, histology, molecular biomarker testing and results, and PD-L1 testing and expression. We geocoded patient and hospital addresses to determine travel time, distance to care, and census block level contextual variables. We compared molecular biomarker and PD-L1 testing rates, the prevalence of molecular biomarkers, and PD-L1 expression levels by race and sex, using χ2 tests. We determined predictors of testing, using multivariable logistic regression and report adjusted ORs and 95%CI. RESULTS: Among patients with nonsquamous NSCLC, 64.4% were tested for molecular biomarkers, and among all NSCLC patients 53.2% were tested for PD-L1 expression. Differences in biomarker testing rates by sociodemographic factors were not statistically significant in univariate or adjusted analyses. Adjusted analyses showed that patients living in areas with higher household internet access were more likely to undergo PD-L1 testing (adjusted OR = 1.66, 95% CI, 1.02-2.71). Sociodemographic differences in molecular biomarker prevalence and PD-L1 expression levels were not statistically significant, except for human epidermal growth factor receptor 2 (HER2) mutations, which occurred in 16.7% of males vs 0% in females, P = .05. INTERPRETATION: Biomarker testing remains underused in NSCLC. Future work should include larger populations and evaluate hospital-specific testing protocols to identify and address barriers to guideline-recommended testing.

Imagining a world without low-value services: progress, barriers, and the path forward.

Low-value services are a major problem in the US health care system. We believe that the coronavirus disease 2019 pandemic's unprecedented impact on the health system, and society writ large, offers an opportunity to reshape the conversation and incentives around low-value services. This article explores current barriers to and opportunities for accelerating progress toward high-value care delivery. We examine how financial and nonfinancial incentives, uncertainty in clinical decision-making, and insufficient partnering with patients and families contribute to the delivery of low-value care. We then explore potential solutions, including making it easier for clinicians to forgo low-value services and providing them with actionable information to make those decisions, expanding payer efforts to develop "value report cards," developing measures that map the adverse health and economic effects of low-value services, and training clinicians and health care leaders to engage in conversations with patients about the personal medical, financial, and psychological harms of low-value services.

Gaps in Evidence-Based Therapy Use in Insured Patients in the United States With Type 2 Diabetes Mellitus and Atherosclerotic Cardiovascular Disease.

Background Evidence-based therapies are generally underused for cardiovascular risk reduction; however, less is known about contemporary patients with type 2 diabetes mellitus and atherosclerotic cardiovascular disease. Methods and Results Pharmacy and medical claims data from within Anthem were queried for patients with established atherosclerotic cardiovascular disease and type 2 diabetes mellitus. Using an index date of April 18, 2018, we evaluated the proportion of patients with a prescription claim for any of the 3 evidence-based therapies on, or covering, the index date ±30 days: high-intensity statin, angiotensin-converting enzyme inhibitor or angiotensin receptor blocker, and sodium glucose cotransporter-2 inhibitor or glucagon-like peptide-1 receptor agonist. The potential benefit of achieving 100% adoption of all 3 evidence-based therapies was simulated using pooled treatment estimates from clinical trials. Of the 155 958 patients in the sample, 24.7% were using a high-intensity statin, 53.1% were using an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker, and 9.9% were using either an sodium glucose cotransporter-2 inhibitor or glucagon-like peptide-1 receptor agonists. Overall, only 2.7% of the population were covered by prescriptions for all 3 evidence-based therapies, and 37.4% were on none of them. Over a 12-month period, 70.6% of patients saw a cardiologist, while only 18% saw an endocrinologist. Increasing the use of evidence-based therapies to 100% over 3 years of treatment could be expected to reduce 4546 major atherosclerotic cardiovascular events (myocardial infarction, stroke, or cardiovascular death) in eligible but untreated patients. Conclusions Alarming gaps exist in the contemporary use of evidence-based therapies in this large population of insured patients with type 2 diabetes mellitus and atherosclerotic cardiovascular disease. These data provide a call to action for patients, providers, industry, regulators, professional societies, and payers to close these gaps in care.

Major fall in urgent skin cancer referrals during the COVID-19 outbreak.

The SARS-CoV-2 cornovirus disease (COVID-19) pandemic has significantly affected referrals of new suspected cancers from primary care to specialist services in the National Health Service (NHS) across the UK.  Amongst the many factors causing delay, such as fear and uncertainty about COVID-19 transmission, reluctance to seek medical attention for cancer sypmtoms and avoiding additional pressure on NHS services, we anticipate a surge in urgent skin cancer referrals to our plastic surgery service as we enter a post-COVID recovery phase.  On the basis of previous referral data and statistical forecasting, we share our predicted numbers against our actual number of urgent skin cancer referrals for the COVID-19 period and, based on this analysis, encourage all cancer services to prepare and allocate resources appropriately for the busy months to follow.

Treatment of post-prostatectomy urinary incontinence and erectile dysfunction: there is insufficient utilisation of care in German cancer survivors.

PURPOSE: Treatment of post-prostatectomy urinary incontinence (UI) and erectile dysfunction (ED) increases quality of life (QoL). Aim of our study was to evaluate the utilisation of care among patients with post-prostatectomy UI and ED in Germany. METHODS: The HAROW study documented treatment of patients with localised prostate cancer (≤ T2c) in Germany. 1260 patients underwent radical prostatectomy (RP). Patients answered validated questionnaires after a median follow-up of 6.3 years. Response rate was 76.8%. RESULTS: Median age at RP was 65 (IQR 60-69) years. 14% (134/936) used more than one pad per day for UI. 25% (26/104, 30 missing) of UI patients underwent surgery to improve continence. Of patients without surgery, 41% (31/75) reported a moderate-to-severe issue concerning their incontinence with worse mental health and QoL. 81% (755/936) patients were unable to have an erection firm enough for sexual intercourse. Of all ED patients, 40% (319/793) used ED treatment regularly or tried it at least once. 49% (243/499) of patients with interest in sex never tried ED treatment. In multivariate analysis, patients not using ED treatments were older (≥ 70 years OR 4.1), and more often had preoperative ED (OR 2.3) and less interest in sex (OR 2.2). Nevertheless, 30% (73/240) of these patients had moderate-to-severe issues with their ED reporting worse mental health and QoL. CONCLUSION: Almost half of the patients without post-prostatectomy UI and ED treatment reported moderate-to-severe issues with a significant decrease in QoL. This indicates an insufficient utilisation of care in Germany.

Management and Outcome of Patients Admitted With Tricuspid Regurgitation in France.

BACKGROUND: Growing evidence shows a major outcome impact and undertreatment of tricuspid regurgitation (TR), but large and comprehensive contemporary reports of management and outcome at the nationwide level are lacking. METHODS: We gathered all consecutive patients admitted with a diagnosis of likely functional TR in 2014-2015 in France from the Programme de Médicalisation des Systèmes d'Information national database and collected rate of surgery, in-hospital mortality, 1-year mortality, or heart failure (HF) readmission rates. RESULTS: In 2014-2015, 17,676 consecutive patients (75 ± 14 years of age, 51% female) were admitted with a TR diagnosis. Charlson index was ≥ 2 in 56% of the population and 46% presented with HF. TR was associated with prior cardiac surgery, ischemic/dilated cardiomyopathy, or mitral regurgitation in 73% of patients. Only 10% of TR patients overall and 67% of those undergoing mitral valve surgery received a tricuspid valve intervention. Among the 13,654 (77%) conservatively managed patients, in-hospital mortality, 1-year mortality, and 1-year mortality or HF readmission rates were 5.1%, 17.8%, and 41%, respectively, overall, and 5.3%,17.2%, and 37%, respectively, among those with no underlying medical conditions (8-fold higher than predicted for age and gender). CONCLUSIONS: This nationwide cohort of patients admitted with TR included elderly patients with frequent comorbidities/underlying cardiac diseases. In patients conservatively managed, mortality and morbidity were considerably high over a short time span. Despite this poor prognosis, only 10% of patients underwent a tricuspid valve intervention. These nationwide data showing a considerable risk and potential underuse of treatment highlight the critical need to develop strategies to improve the management and outcomes of TR patients.

Impact of COVID-19 pandemic on fecal immunochemical test screening uptake and compliance to diagnostic colonoscopy.

BACKGROUND AND AIM: During this COVID-19 pandemic, Taiwan is one of the few countries where fecal immunochemical test and endoscopic activity for colorectal cancer screening keeps ongoing. We aimed to investigate how screening uptake and colonoscopy rate were affected in one of the biggest screening hubs in Northern Taiwan. METHODS: We conducted a prospective observational study tracing and analyzing the screening uptake and the trend of compliance to diagnostic colonoscopy in fecal immunochemical test-positive subjects in the National Taiwan University Hospital screening hub since the outbreak of COVID-19 and compared it with that of the corresponding periods in the past 3 years. Cancellation and rescheduling rates of colonoscopy and related reasons were also explored. RESULTS: Screening uptake during December 2019 to April 2020 was 88.8%, which was significantly lower than that in the corresponding period of the past 3 years (91.2-92.7%, P for trend < 0.0001). Colonoscopy rate in this period was 66.1%, which was also significantly lower than that in the past 3 years (70.2-77.5%, P for trend = 0.017). Rescheduling or cancellation rate was up to 10.9%, which was significantly higher than that in the past 3 years (P for trend = 0.023), and half of them was due to the fear of being infected. CONCLUSION: Fecal immunochemical test screening was significantly affected by COVID-19 pandemic. In order to resume the practice in COVID-19 era, screening organizers should consider various approaches to secure timely diagnosis of colorectal cancer.

El desempeño del primer nivel y su relación con las hospitalizaciones evitables / The primary care performance and its relationship with preventable hospitalizations

INTRODUCCIÓN. El enfoque de atención primaria en el diseño de servicios de salud sigue siendo importante. La coordinación asistencial y la continuidad de la atención son ejes fundamentales para el abordaje de las enfermedades crónicas no transmisibles como la diabetes mellitus, que ha sido catalogada como enfermedad susceptible de cuidados ambulatorios. Las tasas de hospitalización elevadas por este tipo de condiciones reflejan una atención ambulatoria deficiente e inadecuada para el problema de salud estudiado, lo que implica que la población no accedió a la atención, o que esta no es resolutiva. MATERIALES Y MÉTODOS. Se analizaron todas las consultas de emergencia, en 12 meses en un hospital de Quito, se buscaron consultas externas de pacientes en todos los establecimientos de primer nivel del MSP antes de la consulta por emergencia, desde el 1 de enero de 2015 hasta un día antes de la consulta por emergencia. RESULTADOS. De 41 pacientes atendidos con diagnóstico de enfermedades evitables 58% eran mujeres, 43% (18) requirió hospitalización. El promedio de días de hospitalización fue 6,51, con una dispersión de 13,0; el de consultas externas previo a la emergencia fue 3,07, con máximo 22 consultas. Los hospitalizados tuvieron, en promedio, 5,05 consultas externas antes de la emergencia y hospitalización, aproximadamente 4 más que el promedio (0,95) de los pacientes no hospitalizados. DISCUSIÓN. las elevadas tasas de hospitalización podrían reflejar una atención primaria deficiente, lo que implica que la población no accedió a la atención, sin embargo, habría que analizar la gravedad de los pacientes.

INTRODUCTION. Primary care services are important for the delivery of comprehensive health services. The coordination and continuity of care are the main characteristics to approach non-communicable diseases like diabetes mellitus, which has been classified as ambulatory care sensitive condition. The high hospitalization rate might reveal poor and inadequate out-patient care, implying that the population did not access care, or that care was not effective. MATERIALS AND METHODS. All emergency consultations within 12 months in one hospital in Quito were analyzed according to their ICD-10 codes. They were compared with the consultations at the first level of care facilities of the Ministry of Public Health, from January 1st, 2015 until one day before the emergency consultation. RESULTS. Of 41 patients who attended with a diagnosis of preventable diseases 58% were wo-men, 43% (18) required hospitalization. The average number of days of hospitalization was 6.51, with a dispersion of 13.0; the number of external consultations prior to the emergency was 3.07, with a maximum of 22 consultations. The hospitalized patients had, on average, 5.05 outpatient visits before the emergency and hospitalization, approximately 4 more than the average (0.95) of the non-hospitalized patients. DISCUSSION. The high hospitalization rate, due to this condition, might reveal poor and inadequate ambulatory care, nevertheless it is necessary to analyze the severity of the cases in the studs.

Paediatric emergency department visits for non-urgent conditions: Can family medicine prevent this?

BACKGROUND: In Turkey, family physicians serve only during office hours, while emergency services have 7/24 free access. Non-urgent patients commonly use Paediatric Emergency departments (PEDs). In Turkey, there is little evidence as to why emergency services are used instead of family medicine for non-urgent paediatric healthcare. OBJECTIVES: To evaluate the causes and factors affecting non-urgent PED visits. To determine the reason for non-use of family medicine for non-urgent paediatric healthcare. METHODS: We conducted a cross-sectional study at Gaziantep University PED between April and May 2019. We administered a questionnaire to the parents of children (from one month to 16 years) triaged to non-urgent (level-5) using a 5-level triage system. RESULTS: A total of 457 parents were surveyed. The average patient age was 6.5 ± 4.7 years and 24.5% had a chronic disease. One-third of the parents (33.7%) considered their children's condition 'very urgent'. The most important reason for preferring PED (42.5%) instead of family physician or alternative health facilities was the thought that the condition of children would worsen. Two hundred fifty-three (55.4%) of the patients presented outside working hours. Although 58.9% of parents were satisfied with the family physician, most (67.8%) stated that they preferred other specialists rather than family physicians when the child had health problems. Fathers who were primary school graduates were more likely to prefer other specialists than family physicians. CONCLUSION: Parents' perception of urgency and the thought that their child's condition will worsen are the main reasons for non-urgent using PED.

An Asthma Population Health Improvement Initiative for Children With Frequent Hospitalizations.

OBJECTIVES: A relatively small proportion of children with asthma account for an outsized proportion of health care use. Our goal was to use quality improvement methodology to reduce repeat emergency department (ED) and inpatient care for patients with frequent asthma-related hospitalization. METHODS: Children ages 2 to 17 with ≥3 asthma-related hospitalizations in the previous year who received primary care at 3 in-network clinics were eligible to receive a bundle of 4 services including (1) a high-risk asthma screener and tailored education, (2) referral to a clinic-based asthma community health worker program, (3) facilitated discharge medication filling, and (4) expedited follow-up with an allergy or pulmonology specialist. Statistical process control charts were used to estimate the impact of the intervention on monthly 30-day revisits to the ED or hospital. We then conducted a difference-in-differences analysis to compare changes between those receiving the intervention and a contemporaneous comparison group. RESULTS: From May 1, 2016, to April 30, 2017, we enrolled 79 patients in the intervention, and 128 patients constituted the control group. Among the eligible population, the average monthly proportion of children experiencing a revisit to the ED and hospital within 30 days declined by 38%, from a historical baseline of 24% to 15%. Difference-in-differences analysis demonstrated 11.0 fewer 30-day revisits per 100 patients per month among intervention recipients relative to controls (95% confidence interval: -20.2 to -1.8; P = .02). CONCLUSIONS: A multidisciplinary quality improvement intervention reduced health care use in a high-risk asthma population, which was confirmed by using quasi-experimental methodology. In this study, we provide a framework to analyze broader interventions targeted to frequently hospitalized populations.

Underuse of oral anticoagulants in privately insured patients with atrial fibrillation: A population being targeted by the IMplementation of a randomized controlled trial to imProve treatment with oral AntiCoagulanTs in patients with Atrial Fibrillation (IMPACT-AFib).

BACKGROUND: Many studies showing underuse of oral anticoagulants (OACs) in patients with atrial fibrillation (AF) predated the advent of the non-vitamin K antagonist OACs. We retrospectively examined use of OACs in a large commercially insured population. METHODS: Administrative claims data from 4 research partners participating in FDA-Catalyst, a program of the Sentinel Initiative, were queried in September 2017. Patients were included if they were ≥30 years old with ≥365 days of medical/pharmacy coverage, and had ≥2 diagnosis codes for AF, a CHA2DS2-VASc score ≥2, absence of contraindications to OAC use, and no evidence of OAC use in the 365 days before the index AF diagnosis. The main outcome measures of the current analysis were rates of OAC use in the prior 12 months of cohort identification and factors associated with non-use. RESULTS: A total of 197,806 AF patients met the eligibility criteria prior to assessment of OAC treatment. Of these, 179,580 (91%) patients were ≥65 years old and 73,286 (37%) patients were ≥80 years old. Half of the patients (98,903) were randomized to the early intervention arm in the IMPACT-AFib trial and constitute the cohort for this analysis. Of these, 32,295 (33%) had no evidence of OAC use in the prior 12 months. Compared with patients with evidence of OAC use in the prior 12 months, patients without OAC use were more likely to be ≥80 years old, women, and have a history of anemia (51% vs 47%) and less likely to have diabetes (41% vs 44%), history of stroke or TIA (15% vs 19%), and history of heart failure (39% vs 48%). CONCLUSIONS: Despite a high risk of stroke, one-third of privately insured patients with AF and no obvious contraindications to an OAC were not treated with an OAC. There is an unmet need for evidence-based interventions that could lead to greater use of OACs in patients with AF at risk for stroke.
