Evaluating unmet needs in large-volume subcutaneous drug delivery: U.S. payer perspectives on a novel, large-volume on-body delivery system.

OBJECTIVE: Existing healthcare systems face finite resource allocation and budgetary constraints, resulting in a substantial need for innovative solutions to enhance service delivery at reduced costs. A novel, user-friendly on-body delivery system (OBDS) was developed which enables administration of large-volume subcutaneous (SC) drugs in both clinical and home-based settings (at-home healthcare professional [HCP] administration or at-home self-administration). METHODS: This research sought to evaluate the potential economic impact of at-home self- or HCP- administration with the OBDS through a comprehensive review of published literature and semi-structured interviews with 17 US payers representing approximately 227 million covered lives. RESULTS: Published literature on OBDS remains limited, but available research highlights the cost-savings of SC administration due to reduced healthcare resource utilization, particularly with home-based care, and improved patient compliance. In interviews, payers identified several attributes that would help address unmet clinical and economic needs. Clinically, the hidden needle and ease-of-use compared to SC syringe pumps was deemed valuable to improve patient compliance and, as OBDS required minimal training, reduce the risk of administration errors. The flexibility to administer drugs at home (self-administration or HCP-administration) or in-clinic was identified as the most impactful attribute on coverage decision making as it has the greatest potential to reduce costs associated with HCP administration for several therapeutic areas. CONCLUSIONS: Given the ability to help address critical unmet needs for the patient and healthcare system, a large proportion of the payers stated that the novel OBDS would warrant a price premium versus the cost of the standalone SC vial and certainly over the IV counterpart. Future research to quantify the value that OBDS efficiencies could bring to healthcare delivery are warranted.

Overview of alopecia areata for managed care and payer stakeholders in the United States.

Alopecia areata (AA) is an autoimmune disease with a complex pathophysiology resulting in nonscarring hair loss in genetically susceptible individuals. We aim to provide health care decision makers an overview of the pathophysiology of AA, its causes and diagnosis, disease burden, costs, comorbidities, and information on current and emerging treatment options to help inform payer benefit design and prior authorization decisions. Literature searches for AA were conducted using PubMed between 2016 and 2022 inclusive, using search terms covering the causes and diagnosis of AA, pathophysiology, comorbidities, disease management, costs, and impact on quality of life (QoL). AA is a polygenic autoimmune disease that significantly impacts QoL. Patients with AA face economic burden and an increased prevalence of psychiatric disease, as well as numerous systemic comorbidities. AA is predominantly treated using corticosteroids, systemic immunosuppressants, and topical immunotherapy. Currently, there are limited data to reliably inform effective treatment decisions, particularly for patients with extensive disease. However, several novel therapies that specifically target the immunopathology of AA have emerged, including Janus kinase (JAK) 1/2 inhibitors such as baricitinib and deuruxolitinib, and the JAK3/tyrosine kinase expressed in hepatocellular carcinoma (TEC) family kinase inhibitor ritlecitinib. To support disease management, a disease severity classification tool, the Alopecia Areata Severity Scale, was recently developed that evaluates patients with AA holistically (extent of hair loss and other factors). AA is an autoimmune disease often associated with comorbidities and poor QoL, which poses a significant economic burden for payers and patients. Better treatments are needed for patients, and JAK inhibitors, among other approaches, may address this tremendous unmet medical need.

Identification of an Optimal COVID-19 Booster Allocation Strategy to Minimize Hospital Bed-Days with a Fixed Healthcare Budget.

Healthcare decision-makers face difficult decisions regarding COVID-19 booster selection given limited budgets and the need to maximize healthcare gain. A constrained optimization (CO) model was developed to identify booster allocation strategies that minimize bed-days by varying the proportion of the eligible population receiving different boosters, stratified by age, and given limited healthcare expenditure. Three booster options were included: B1, costing US $1 per dose, B2, costing US $2, and no booster (NB), costing US $0. B1 and B2 were assumed to be 55%/75% effective against mild/moderate COVID-19, respectively, and 90% effective against severe/critical COVID-19. Healthcare expenditure was limited to US$2.10 per person; the minimum expected expense using B1, B2, or NB for all. Brazil was the base-case country. The model demonstrated that B1 for those aged <70 years and B2 for those ≥70 years were optimal for minimizing bed-days. Compared with NB, bed-days were reduced by 75%, hospital admissions by 68%, and intensive care unit admissions by 90%. Total costs were reduced by 60% with medical resource use reduced by 81%. This illustrates that the CO model can be used by healthcare decision-makers to implement vaccine booster allocation strategies that provide the best healthcare outcomes in a broad range of contexts.

Health insurance coverage and switching among people with hemophilia A in the United States.

BACKGROUND: Hemophilia A (HA) is marked by substantial economic burden, including costs of ongoing treatment, increased monitoring, bleed events, and other health care utilization associated with managing the disease and comorbidities related to the disease. Gene therapies and other anticipated breakthrough treatments hold potential to substantially offset long-term traditional factor VIII (FVIII) prophylaxis in specific populations. Fragmentation of the US insurance system, however, may impact payers' approaches to coverage of new treatments, given concerns about patients "switching" insurance and the payer's ability to offset costs over time. OBJECTIVE: To assess insurance coverage and switching across payers among people with severe HA (SHA) using real-world data. METHODS: Adult men with SHA (FVIII measuring < 1%) in the American Thrombosis and Hemostasis Network dataset between January 2013 and September 2019 were identified. Patients' primary insurance category (ie, commercial, Medicaid, Medicare) and insurance switching over time were described. Outcomes included distribution of current primary insurance coverage by category and mean years of coverage per payer for commercially insured patients, including those with 2 or more commercial payers, and for those who switched insurance categories (eg, coverage by a commercial payer and government payer). RESULTS: Among the cohort of patients with SHA (N = 3,677), 51.9% had commercial primary insurance and 29.0% had coverage by Medicaid (including state-funded programs). The mean duration of follow-up in the database was 6.3 years for patients with at least 1 year of follow-up. Among patients who had ever been commercially insured, 74.9% had the same commercial payer for the entire follow-up period. The mean time covered by the same commercial insurance was 4.8 years. Only 7.5% of patients switched insurance categories (eg, from commercial to Medicaid). Among those who switched categories, patients averaged 3.9 years of commercial coverage, 4.0 years of Medicaid coverage, and 4.8 years of Medicare coverage during the follow-up period. CONCLUSIONS: Both commercially and government-insured patients with SHA typically maintain continuous coverage for extended periods, with limited switching between payers and insurance categories over time. These findings suggest that should breakthrough treatments be approved, payers would likely be able to realize substantial cost savings associated with avoiding long-term prophylactic therapies during the several years after treatment.

Association Between Formulary Coverage and Use of Abuse-Deterrent Prescription Opioids, Risk for Abuse or Overdose, and Associated Healthcare Resource Utilization.

BACKGROUND: Significant public health concerns exist regarding the misuse and abuse of prescription opioids. Abuse-deterrent formulation (ADF) opioids may be leveraged as an important tool for combating the current opioid crisis. OBJECTIVES: To evaluate the relationships between ADF opioid formulary coverage and the ADF utilization rate, the risk for opioid abuse or overdose, opioid abuse or overdose-related healthcare resource utilization, and medical costs within a calendar year. METHODS: This cross-sectional multiyear panel study included adults prescribed an opioid medication in 2015 or 2016. We analyzed the medical and pharmacy claims linked to health plan benefit design data. An ADF opioid-including reformulated oxycodone hydrochloride (HCl) controlled-release (CR; reformulated OxyContin), morphine sulfate and naltrexone HCl extended-release (ER; Embeda), and hydrocodone bitartrate ER (Hysingla ER)-was considered covered if it was listed on the health plan's formulary. Generalized linear models were used to assess the association between ADF opioid formulary coverage and the study outcomes. RESULTS: Of 1,350,607 eligible patients, those enrolled in health plans with coverage of ADF opioids were more likely to fill a prescription for an ADF opioid than those enrolled in plans that did not cover ADF opioids. The risk for opioid abuse or overdose was significantly lower among patients enrolled in plans with broader ADF coverage (adjusted odds ratio [OR], 0.91; 95% confidence interval [CI], 0.86-0.95 for oxycodone HCl CR only vs no ADF coverage; adjusted OR, 0.70; 95% CI, 0.67-0.73 for oxycodone HCl CR plus ≥1 ADF opiods vs no ADF; adjusted OR, 0.77; 95% CI, 0.73-0.81 for oxycodone HCl CR plus ≥1 ADF opiods vs oxycodone HCl CR only; all P <.0001). Approximately 15% and 25% reductions in the opioid abuse or overdose-related hospitalization rate and medical costs were observed for those in the oxycodone HCl CR plus ≥1 ADF opioids coverage group versus those without ADF opioid coverage. CONCLUSIONS: Broad formulary coverage of ADF opioids is associated with reduced rates of opioid abuse or overdose in real-world managed care populations. Health plan administrators and policymakers may consider improving the formulary coverage of ADF opioids as a strategy to ensure appropriate patient access to necessary pain medications while mitigating risk for opioid abuse or overdose.

Recognizing that Evidence is Made, not Born.

Therapeutic product development, licensing and reimbursement may seem a well-oiled machine, but continuing high attrition rates, regulatory refusals, and patients' access issues suggest otherwise; despite serious efforts, gaps persist between stakeholders' stated evidence requirements and actual evidence supplied. Evidentiary deficiencies and/or human tendencies resulting in avoidable inefficiencies might be further reduced with fresh institutional cultures/mindsets, combined with a context-adaptable practices framework that integrates emerging innovations. Here, Structured Evidence Planning, Production, and Evaluation (SEPPE) posits that evidence be treated as something produced, much like other manufactured goods, for which "built-in quality" (i.e., "people" and "process") approaches have been successfully implemented globally. Incorporating proactive, iterative feedback-and-adjust loops involving key decision-makers at critical points could curtail avoidable evidence quality and decision hazards-pulling needed therapeutic products with high quality evidence of beneficial performance through to approvals. Critical for success, however, is dedicated, long-term commitment to systemic transformation.

The Effect of a Pediatric Rare Disease on Subscriber Retention Rates for Commercial Health Insurers in the United States.

BACKGROUND: The advent of personalized medicine creates opportunities for regenerative therapies to deliver extended clinical benefit from a single administration. Policymakers and health insurers in the United States are evaluating coverage and payment arrangements for these therapies. One challenge involved in these evaluations is the perception that subscribers change insurers relatively often. However, the effect of pediatric rare diseases on retention rates for commercial health insurers has not been well studied. OBJECTIVE: To develop estimates for subscriber retention by a commercial insurer for up to 10 years. METHODS: Three population cohorts were examined: (1) all subscribers, (2) subscribers with any dependent aged 16 years or younger, and (3) subscribers with any dependent aged 16 years or younger diagnosed with a chronic rare disease that typically results in a debilitating state or high mortality, usually associated with high health care costs regardless of whether a treatment is available. The analysis was conducted for a sample of fully insured and self-insured group business within the commercial health insurance market for these study cohorts. The MarketScan Commercial Claims and Encounters research database covering the time period from January 1, 2007, through December 31, 2016, was used as the basis for the analysis. Subscribers were included in the family-based cohorts beginning with the first observed month with a dependent aged 16 years or younger and were retained in the analysis until the subscriber or insurer withdrew from the dataset (whichever came first). Subscribers were included in the family-based rare disease cohorts if their qualifying dependent was reported with at least 2 occurrences for any of the rare diseases studied. A Kaplan-Meier estimator was used to produce retention rates for all populations for up to 120 months. An adjustment for interval censoring was applied to the family-based cohorts. A log rank test with chi-square statistic was used to determine statistical significance. RESULTS: The analysis found that the subscriber retention rate within the self-insured groups was higher than within the fully insured groups (P < 0.0001). In addition, the probability of retaining subscribers with a dependent aged 16 years or younger compared with all subscribers was significantly greater (P < 0.0001). The analysis also found the probability of retaining subscribers with a qualifying dependent with a rare disease compared with subscribers with any dependent aged 16 years or younger was significantly greater (P < 0.0001). CONCLUSIONS: This study demonstrated that families with a child with a rare disease remained with their commercial health insurer longer than families who did not have a child with a rare disease. The analysis will be a useful resource when evaluating alternative payment arrangements and cost/benefit analyses of regenerative therapies that offer an extended duration of clinical benefit.

Secular trends in opioid prescribing in the USA.

Opioid abuse and misuse in the USA is a public health crisis. The use of prescription opioid analgesics increased substantially from 2002 through 2010, then plateaued and began to decrease in 2011. This study examined prescriptions of branded and generic immediate- and extended-release opioid analgesics from 1992 to 2016. This was juxtaposed against state and federal policies designed to decrease overutilization and abuse, as well as the launch of new opioid products, including opioids with abuse-deterrent properties (OADPs). The data indicate that these health policies, including the utilization and reimbursement of OADPs, have coincided with decreased opioid utilization. The hypothesis that OADPs will paradoxically increase opioid prescribing is not supported.

Advancing Value Assessment in the United States: A Multistakeholder Perspective.

Rising costs without perceived proportional improvements in quality and outcomes have motivated fundamental shifts in health care delivery and payment to achieve better value. Aligned with these efforts, several value assessment frameworks have been introduced recently to help providers, patients, and payers better understand the potential value of drugs and other interventions and make informed decisions about their use. Given their early stage of development, it is imperative to evaluate these efforts on an ongoing basis to identify how best to support and improve them moving forward. This article provides a multistakeholder perspective on the key limitations and opportunities posed by the current value assessment frameworks and areas of and actions for improvement. In particular, we outline 10 fundamental guiding principles and associated strategies that should be considered in subsequent iterations of the existing frameworks or by emerging initiatives in the future. Although value assessment frameworks may not be able to meet all the needs and preferences of stakeholders, we contend that there are common elements and potential next steps that can be supported to advance value assessment in the United States.

Association Between Patient-Centered Medical Homes and Adherence to Chronic Disease Medications: A Cohort Study.

BACKGROUND: Despite the widespread adoption of patient-centered medical homes into primary care practice, the evidence supporting their effect on health care outcomes has come primarily from geographically localized and well-integrated health systems. OBJECTIVE: To assess the association between medication adherence and medical homes in a national patient and provider population, given the strong ties between adherence to chronic disease medications and health care quality and spending. DESIGN: Retrospective cohort study. SETTING: Claims from a large national health insurer. PATIENTS: Patients initiating therapy with common medications for chronic diseases (diabetes, hypertension, and hyperlipidemia) between 2011 and 2013. MEASUREMENTS: Medication adherence in the 12 months after treatment initiation was compared among patients cared for by providers practicing in National Committee for Quality Assurance-recognized patient-centered medical homes and propensity score-matched control practices in the same Primary Care Service Areas. Linear mixed models were used to examine the association between medical homes and adherence. RESULTS: Of 313 765 patients meeting study criteria, 18 611 (5.9%) received care in patient-centered medical homes. Mean rates of adherence were 64% among medical home patients and 59% among control patients. Among 4660 matched control and medical home practices, medication adherence was significantly higher in medical homes (2.2% [95% CI, 1.5% to 2.9%]). The association between medical homes and better adherence did not differ significantly by disease state (diabetes, 3.0% [CI, 1.5% to 4.6%]; hypertension, 3.2% [CI, 2.2% to 4.2%]; hyperlipidemia, 1.5% [CI, 0.6% to 2.5%]). LIMITATION: Clinical outcomes related to medication adherence were not assessed. CONCLUSION: Receipt of care in a patient-centered medical home is associated with better adherence, a vital measure of health care quality, among patients initiating treatment with medications for common high-cost chronic diseases.

Payer view of personalized medicine.

PURPOSE: The process and methods used by payers when evaluating coverage of personalized medicine testing are described. SUMMARY: Personalized medicine encompasses a number of diagnostic tools that measure drug metabolism, genetic risk for disease development, and tumor type or markers that can guide oncology treatments. However, whole genome testing, tumor marker testing, and testing for drug metabolism are additional costs to the healthcare system. In order to justify these costs, payers and health technology assessment bodies must evaluate the individual tests or groups of tests on their own merits. In order for a test to be covered by payers, test developers must demonstrate clinical utility as measured by improved outcomes or well-informed decision-making. In the United States, payers generally focus on clinical benefit to individual patients and benefits to the healthcare system. Clinical benefits include improved outcomes. Benefits to the healthcare system are generally considered to be cost offsets, which may be due to reductions in the use of unnecessary interventions or to more efficient use of resources. Provider organizations have been assuming more responsibility and liability for healthcare costs through various risk arrangements, including accountable care organizations and patient-centered medical homes. Diagnostic tests that increase efficiency, reduce unnecessary interventions, and improve outcomes will be chosen by specialists in provider organizations. CONCLUSION: For personalized medicine approaches to be adopted and covered by health plans, the methods must be shown to be analytically and clinically valid and provide clinical utility at a reasonable level of cost-effectiveness to payers.

Genomic testing in oncology to improve clinical outcomes while optimizing utilization: the evolution of diagnostic testing.

Cancer care is costly, particularly when chemotherapy and its supportive costs are considered. Yet, chemotherapy is not the right course for every patient. Patients with cancer need appropriate treatment that will give them the best possible outcome. Personalized medicine has become an important area of oncology. In addition to genetic testing, genomic testing has become a useful tool in diagnostics. For genomic assays to be viable, they must have clinical validity, analytic validity, and clinical utility. Stakeholders are willing to provide coverage for such testing through medical policy when there is strong evidence the tests are effective. Genomic testing can be used in decision making to rule out chemotherapy or other treatment options that would not be effective for the care of an individual patient. The use of genomic testing to help eliminate ineffective or possible harmful treatment options and determine appropriate care will benefit the patient while reducing healthcare utiliztion and costs.

Brief Report: Intensification to Triple Therapy After Treatment With Nonbiologic Disease-Modifying Antirheumatic Drugs for Rheumatoid Arthritis in the United States From 2009 to 2014.

OBJECTIVE: Several trials suggest that triple therapy (methotrexate, sulfasalazine, and hydroxychloroquine) and biologic disease-modifying antirheumatic drugs (DMARDs) have similar efficacy in patients with rheumatoid arthritis (RA). This study was undertaken to investigate intensification to triple therapy after initial nonbiologic prescription among patients with RA. METHODS: The use of triple therapy among patients with RA in 2009-2014 was evaluated using US insurance claims data. Patients with a health care visit for RA and an initial nonbiologic DMARD prescription were included. Frequencies of intensification to triple therapy or a biologic DMARD and rates of intensification per 6-month time period were calculated. Using Cox regression, we evaluated whether sociodemographic, temporal, geographic, clinical, and health care utilization factors were associated with intensification to triple therapy. Among those patients whose therapy was intensified, we investigated factors associated with triple therapy use by logistic regression. Hazard ratios (HRs) with 95% confidence intervals (95% CIs) for intensification to triple therapy in relation to various clinical and demographic factors were calculated. RESULTS: There were 24,576 patients with a mean ± SD age of 50.3 ± 12.3 years, and 78% were female. During the study period, treatment was intensified to biologic DMARDs in 2,739 patients (11.1%) compared to 181 patients (0.7%) whose treatment was intensified to triple therapy. There was no significant change in triple therapy use across calendar years. Patients whose treatment was intensified to triple therapy were more likely to receive glucocorticoids (HR 1.91 [95% CI 1.41-2.60]) compared to patients who did not use glucocorticoids and were more likely to use nonsteroidal antiinflammatory drugs (NSAIDs) (HR 1.48, 95% CI 1.10-1.99 versus no NSAID use). Among those patients whose treatment was intensified to triple therapy or biologic DMARDs, factors significantly associated with triple therapy use included older age, US region (with the highest odds for triple therapy use in the West and lowest odds for triple therapy use in the Northeast), glucocorticoid use, and lower number of outpatient visits within 180 days of initial nonbiologic DMARD prescription. CONCLUSION: Despite reports published during the study period suggesting equivalent efficacy of triple therapy and biologic DMARDs for RA, the use of triple therapy was infrequent and did not increase over time in this large nationwide study.

Initial choice of oral glucose-lowering medication for diabetes mellitus: a patient-centered comparative effectiveness study.

IMPORTANCE: Although many classes of oral glucose-lowering medications have been approved for use, little comparative effectiveness evidence exists to guide initial selection of therapy for diabetes mellitus. OBJECTIVE: To determine the effect of initial oral glucose-lowering agent class on subsequent need for treatment intensification and 4 short-term adverse clinical events. DESIGN, SETTING, AND PARTICIPANTS: This study was a retrospective cohort study of patients who were fully insured members of Aetna (a large national health insurer) who had been prescribed an oral glucose-lowering medication from July 1, 2009, through June 30, 2013. Individuals newly prescribed an oral glucose-lowering agent who filled a second prescription for a medication in the same class and with a dosage at or above the World Health Organization's defined daily dose within 90 days of the end-of-day's supply of the first prescription were studied. Individuals with interim prescriptions for other oral glucose-lowering medications were excluded. EXPOSURES: Initiation of treatment with metformin, a sulfonylurea, a thiazolidinedione, or a dipeptidyl peptidase 4 inhibitor. MAIN OUTCOMES AND MEASURES: Time to addition of a second oral agent or insulin, each component separately, hypoglycemia, other diabetes-related emergency department visits, and cardiovascular events. RESULTS: A total of 15 516 patients met the inclusion criteria, of whom 8964 (57.8%) started therapy with metformin. In unadjusted analyses, use of medications other than metformin was significantly associated with an increased risk of adding a second oral agent only, insulin only, and a second agent or insulin (P < .001 for all). In propensity score and multivariable-adjusted Cox proportional hazards models, initiation of therapy with sulfonylureas (hazard ratio [HR], 1.68; 95% CI, 1.57-1.79), thiazolidinediones (HR, 1.61; 95% CI, 1.43-1.80), and dipeptidyl peptidase 4 inhibitors (HR, 1.62; 95% CI, 1.47-1.79) was associated with an increased hazard of intensification. Alternatives to metformin were not associated with a reduced risk of hypoglycemia, emergency department visits, or cardiovascular events. CONCLUSIONS AND RELEVANCE: Despite guidelines, only 57.8% of individuals began diabetes treatment with metformin. Beginning treatment with metformin was associated with reduced subsequent treatment intensification, without differences in rates of hypoglycemia or other adverse clinical events. These findings have significant implications for quality of life and medication costs.

Patterns of initiation of oral anticoagulants in patients with atrial fibrillation- quality and cost implications.

BACKGROUND: Dabigatran, rivaroxaban, and apixaban have been approved for use in patients with atrial fibrillation based upon randomized trials demonstrating their comparable or superior efficacy and safety relative to warfarin. Little is known about their adoption into clinical practice, whether utilization is consistent with the controlled trials on which their approval was based, and how their use has affected health spending for patients and insurers. METHODS: We used medical and prescription claims data from a large insurer to identify patients with nonvalvular atrial fibrillation who were prescribed an oral anticoagulant in 2010-2013. We plotted trends in medication initiation over time, assessed corresponding insurer and patient out-of-pocket spending, and evaluated the cumulative number and cost of anticoagulants. We identified predictors of novel anticoagulant initiation using multivariable logistic models. Finally, we estimated the difference in total drug expenditures over 6 months for patients initiating warfarin versus a novel anticoagulant. RESULTS: There were 6893 patients with atrial fibrillation that initiated an oral anticoagulant during the study period. By the end of the study period, novel anticoagulants accounted for 62% of new prescriptions and 98% of anticoagulant-related drug costs. Female sex, lower household income, and higher CHADS2, CHA2DS2-VASC, and HAS-BLED scores were significantly associated with lower odds of receiving a novel anticoagulant (P <.001 for each). Average combined patient and insurer anticoagulant spending in the first 6 months after initiation was more than $900 greater for patients initiating a novel anticoagulant. CONCLUSIONS: This study demonstrates rapid adoption of novel anticoagulants into clinical practice, particularly among patients with lower CHADS2 and HAS-BLED scores, and high health care cost consequences. These findings provide important directions for future comparative and cost-effectiveness research.

Practical perspectives on the management of overweight and obesity.

The prevalence of obesity, defined as a body mass index of 30 or more, has reached epidemic proportions in the United States. Obesity is associated with an increased risk of multiple conditions, including type 2 diabetes mellitus, cardiovascular disease, arthritis, and sleep apnea. To discuss issues related to obesity in the workplace, healthcare, and managed care settings, stakeholders from these areas participated in a roundtable discussion on several topics, including the management of obesity, managed care coverage policies for obesity treatments, and potential strategies for improving patient outcomes. Participants agreed that obesity is a challenging condition to treat. Lifestyle modification, one of the most commonly recommended treatment modalities, is often inadequate on its own, as patients are unable to maintain weight loss over time. Although lifestyle modification remains important, additional tools are needed. In patients who undergo bariatric surgery, lifestyle modification is also necessary for long-term weight maintenance; however, surgery is not appropriate for all patients. Pharmacologic treatment may also be considered, but cost and managed care coverage policies have the potential to limit patient access to this treatment modality. Increased awareness and additional efforts on the part of all stakeholders are needed to improve outcomes for patients affected by obesity.

Research to real-world application: experts weigh in on the underuse of anticoagulants.

Although numerous studies have shown that anticoagulants can reduce the risk of stroke and thromboembolic events in patients with nonvalvular atrial fibrillation, they are underprescribed in the clinical setting. While standardized risk scoring assessments are recommended in treatment guidelines to determine when anticoagulant use may be appropriate, they are not widely used in the real-world clinical setting. Many factors contribute to anticoagulant underuse, including patient characteristics and comorbidities. Reluctance to prescribe an anticoagulant may also stem from concerns about bleeding or other perceived risks. In addition, physicians may be discouraged from prescribing anticoagulant therapy, particularly warfarin, if follow-up care and monitoring is potentially unfeasible. Patient fears of treatment and lack of access to the healthcare system also contribute to underuse. Increased awareness and education, medical therapy management programs, better care coordination, and improvements in monitoring and follow-up programs may help to increase the use of anticoagulant therapies in appropriate patients.

Considerations for the optimal use of immunoglobulin.

Immunoglobulins are large Y-shaped proteins produced by B-cells and plasma cells that are used by the immune system to identify and neutralize foreign objects such as bacteria and viruses. Immunoglobulin G (IgG) preparations are approved by the US Food and Drug Administration for the treatment of primary immunodeficiency disease, idiopathic thrombocytopenic purpura, Kawasaki disease, chronic lymphocytic leukemia with frequent infections, bone marrow transplantation, to prevent infection in pediatric human immunodeficiency virus, and chronic inflammatory demyelinating polyneuropathy. However, IgG products are frequently used off label in many autoimmune conditions. The advent of numerous intravenous and subcutaneous formulations of IgG presents new opportunities impacting patient preferences, site of care, and costs. The appropriate and optimal use of IgG is reviewed based on discussions from an expert roundtable panel and review of the scientific literature. Clinicians and payers should consider patient preferences, evidence- based guidelines, and policies when selecting an IgG product.
