RESUMEN
Purpose: To investigate the association of filling opioid prescriptions with healthcare service utilization among a nationally representative sample of adults with disability. Materials and Methods: The Medical Expenditure Panel Survey (MEPS) for 2010-2015, Panels 15-19, was used to identify adults who were prescribed opioids during each two-year period. We examined the data for associations between opioid prescription filling and the number of emergency department (ED) visits and hospitalizations. The participants were grouped as those with inflammatory conditions or with longstanding physical disability, and a comparison group of those without these conditions. Results and conclusions: Opioid prescription filling differed among adults with inflammatory conditions and longstanding physical disability compared to the comparison group (44.93% and 40.70% vs 18.10%, respectively). For both groups of people with disability, the relative rates for an ED visit or hospitalization were significantly higher for those who filled an opioid prescription, compared to adults with the same conditions who did not fill an opioid prescription. People with a longstanding physical disability who filled an opioid prescription had the highest rate ratio of ED use and hospitalization. Results from this investigation demonstrate that opioid prescription filling among persons with inflammatory conditions and longstanding physical disabilities is associated with higher rates of ED visits and hospitalizations.
RESUMEN
In 2021, the US Food and Drug Administration (FDA) granted approval to aducanumab, an antiamyloid antibody for early-stage Alzheimer's disease, despite a lack of clear clinical evidence demonstrating the drug's cognitive benefits. The manufacturer initially priced the drug at a staggering $56,000 per year, a price that was later reduced to $28,200. Unfortunately, these costs do not include the additional expenses associated with monitoring the treatment. However, the Centers for Medicare and Medicaid Services (CMS) recently announced that they will only cover individuals enrolled in clinical trials and will limit coverage of future antiamyloid antibodies. This discrepancy between the FDA and CMS positions has caused confusion and concerns for patients who could potentially benefit from antiamyloid therapy. It is important to acknowledge the clinical and economic uncertainties surrounding aducanumab and its potential impacts on future antiamyloid drug development and approval processes. The FDA's approval, despite limited clinical evidence, raises questions about the integrity and rigor of the approval process. The drug's high cost also raises accessibility concerns, especially for those without insurance or sufficient financial resources. Given the CMS's limited coverage policy, it's critical to evaluate the long-term implications of this decision on future antiamyloid drug development. Without adequate support and coverage from insurance providers, the development and approval of future Alzheimer's treatments may be hindered. In summary, the approval and pricing of aducanumab, coupled with the CMS's limited coverage policy, has created a confusing and concerning landscape for Alzheimer's patients. It's important that stakeholders, including patients, clinicians, insurers, and regulatory bodies, work together to address these challenges and ensure that individuals with Alzheimer's have access to effective, affordable treatments.
RESUMEN
INTRODUCTION: The economic and clinical implications of eradicating Helicobacter pylori ( H. pylori ) with vonoprazan-based and rifabutin-based regimens vs other existing prepackaged first-line treatment options in the United States are unknown. Therefore, we evaluated the cost-effectiveness of vonoprazan-based and rifabutin-based and other prepackaged regimens for the first-line treatment of H. pylori from the perspective of US healthcare payers. METHODS: We used the state-transition Markov model to conduct a cost-effectiveness analysis of H. pylori eradication with clarithromycin triple, bismuth quadruple, vonoprazan dual, vonoprazan triple, and rifabutin triple regimens. In a cycle length of 2 months, the model estimated the expected costs (expressed in 2022 US$), expected quality-adjusted life-years (QALY), incremental cost-effectiveness ratios, and expected net monetary benefit over 20 years. In addition, we accounted for the present value of future costs and QALY by applying a 3% discounting rate. RESULTS: In this study, rifabutin triple therapy had a lower expected cost but was more effective than clarithromycin triple, bismuth quadruple, and vonoprazan dual regimens; hence, it dominated them. Vonoprazan triple therapy had a higher expected cost (US$ 1,172 vs US$ 1,048) and expected QALY (14.262 vs 14.256) than rifabutin triple therapy, yielding an estimated incremental cost-effectiveness ratio of US$ 22,573/QALY. The study suggested that vonoprazan triple treatment had the highest expected net monetary benefit and was the most cost-effective at willingness-to-pay thresholds between US$50,000 and US$150,000 per QALY, followed by rifabutin triple therapy. DISCUSSION: H. pylori infection eradication with vonoprazan triple therapy would provide the greatest net health and monetary benefit from the perspective of US healthcare payers.

Objective: This study aimed to examine the association of nonsteroidal anti-inflammatory drug (NSAID) use by pregnant women during pregnancy with autism spectrum disorder (ASD) and intellectual disability (ID) in their children among Medicaid-insured mother-child dyads. Materials and Methods: We conducted a retrospective cohort study linking multiple datasets of South Carolina for the years between 2010 and 2017, in which the main exposure variable was NSAID use during pregnancy and outcome variables were ASD only, ID only, and ASD with ID. We conducted a multinomial logistic regression analysis, controlling for identified risk factors for ASD (mother's age, race, body-mass index, preeclampsia, and gestational diabetes). Results: NSAID use during pregnancy was found to be associated with ID only in both unadjusted and adjusted analyses. Children with mothers who had NSAID prescriptions were 26% more likely to have ID in comparison with children whose mothers did not have NSAID prescriptions (odds ratio: 1.26 [1.10-1.46]). The other risk factors identified for ASD were maternal age, race, preeclampsia, smoking, low birth weight, and obesity. For ID, the risk factors were maternal age, race, smoking, birth weight, overweight, and obesity, all of which were also associated with ASD with ID, except for overweight. Conclusions: NSAID usage during pregnancy was found to be associated with ID only and not with ASD. However, more research is needed to validate the effect of NSAIDs during pregnancy on ASD and ID among children.

Association between protease inhibitors (PI) and Type II diabetes mellitus (T2DM) in human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) patients is largely debated. This study examined the odds of developing T2DM among HIV/AIDS Medicare beneficiaries treated with PI and possible racial disparities in the odds. We performed a nested casecontrol study of Medicare database 2013-2017. We included HIV/AIDS positive beneficiaries who were enrolled continuously in Medicare Part A/B with no previous history of T2DM. PI-users were matched to non-PI users and non-anti-retroviral therapies (ART) users using a1:1 greedy propensity score (PS) matching . Multivariablee logistic regressions were performed to assess the odds of developing T2DM. The analysis included 2,353 HIV/AIDS beneficiaries. Matched samples were generated for PI vs. non-PI groups (n = 484) and PI vs. non-ART groups (n = 490). Compared to the non-PI group, the odds of developing T2DM were higher in PI-users (AOR: 1.76; 95% CI: 1.17-2.64), in Caucasian PI-users (AOR: 1.81; 95% CI: 1.02-3.22) and in African-American PI-users (AOR: 1.86; 95% CI: 1.03-3.36). Compared to the non-ART group, the odds of developing T2DM were higher in PI-users (AOR: 1.87; 95% CI: 1.25-2.81), in Caucasian PI-users (AOR: 1.96; 95% CI: 1.14-3.39) and in African-American PI-users (AOR: 2.05; 95% CI: 1.03-4.09). The use of PI is associated with higher odds of T2DM; odds were higher among African-Americans than Caucasians.

Clinical management of human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) is progressing to include chronic/metabolic complications, which may impose a significant economic burden on beneficiaries and Medicare. We assessed the national economic impact of comorbid Type-II Diabetes Mellitus (T2DM) on HIV/AIDS patients and potential raical disparities. This study was a cross-sectional study of Medicare database 2013-2017. Analytical sample included HIV/AIDS positive beneficiaries continuously enrolled in Part A/B. Total medical costs, prescription costs, inpatient costs, outpatient costs, out-of-pocket (OOP) costs, and Medicare costs were assessed from Medicare claims. Generalized linear models with log-link and gamma distribution were used to examine the impact of T2DM on different costs. A total of 2,509 eligible HIV/AIDS positive beneficiaries were identified of which 19.9% (n=498) had T2DM. After adjusting for covariates, T2DM beneficiaries had higher inpatient costs: 63.34% (95% CI: 42.73%-86.94%), outpatient costs: 50.26% (95% CI: 30.70%-72.75%), Medicare costs: 27.95% (95% CI: 13.81%-43.84%), OOP costs: 59.15% (95% CI: 40.02%-80.92%), and total medical costs: 27.83% (95% CI: 14.27%-43.00%) than non-T2DM beneficiaries. Incremental costs were higher among African Americans than Caucasians. Comorbid T2DM mposes a significant economic burden on HIV/AIDS patients and Medicare, which is higheramong African Americans.

PURPOSE: Standard survival models are often used in a medication persistence analysis. These methods implicitly assume that all patients will experience the event (medication discontinuation), which may bias the estimation of persistence if long-term medication persistent patients rate is expected in the population. We aimed to introduce a mixture cure model in the medication persistence analysis to describe the characteristics of long-term and short-term persistent patients, and demonstrate its application using a real-world data analysis. METHODS: A cohort of new users of statins was used to demonstrate the differences between the standard survival model and the mixture cure model in the medication persistence analysis. The mixture cure model estimated effects of variables, reported as odds ratios (OR) associated with likelihood of being long-term persistent and effects of variables, reported as hazard ratios (HR) associated with time to medication discontinuation among short-term persistent patients. RESULTS: Long-term persistent rate was estimated as 17% for statin users aged between 45 and 55 versus 10% for age less than 45 versus 4% for age greater than 55 via the mixture cure model. The HR of covariates estimated by the standard survival model (HR = 1.41, 95% CI = [1.35, 1.48]) were higher than those estimated by the mixture cure model (HR = 1.32, 95% CI = [1.25, 1.39]) when comparing patients with age greater than 55 to those between 45 and 55. CONCLUSIONS: Compared with standard survival modeling, a mixture cure model can improve the estimation of medication persistence when long-term persistent patients are expected in the population.

BACKGROUND: Nationally, individuals with disability have higher rates of opioid use and misuse and are prescribed higher doses than those without disability. Opioid prescriptions during pregnancy are associated with adverse birth outcomes. OBJECTIVE: To understand the difference in opioid prescribing during pregnancy over time by disability status among Medicaid beneficiaries who gave birth from 2008 to 2017 in South Carolina. METHODS: Data from hospital discharges, vital records, and pharmacy were linked to determine the mother's disability status, opioid prescriptions filled during pregnancy, and other maternal characteristics. Disability status was characterized into physical disability, inflammatory conditions, intellectual and developmental disabilities (IDD), and psychiatric conditions. Bivariate analyses and negative binomial regression were utilized to obtain adjusted rate ratios for total opioid prescriptions and total morphine milligram equivalents (MME) during pregnancy per live birth. Models were adjusted for chronic pain status. The final analytic sample included 319,752 births to 224,838 mothers. RESULTS: Almost 7% of the births were to mothers with at least one type of disability. Overall, those with disability had a significantly higher adjusted rate ratio of total opioid prescriptions (aRR: 2.36; 95% CI: 2.21-2.52) and total MME (aRR: 2.29; 95% CI: 2.07-2.52) during pregnancy per live birth than those without disability. These findings were seen across all the diagnostic groups, except IDD, where there were no significant differences. CONCLUSIONS: The current study found that women with physical, inflammatory, and psychiatric disability were prescribed more opioids and at higher dosages during pregnancy than their counterparts without disability, after adjusting for chronic pain status.

BACKGROUND: Streptococcus pneumoniae is an important pathogen responsible for severe pneumococcal diseases, including pneumonia, bacteraemia/sepsis, and meningitis. Inflammatory bowel disease [IBD] patients have an increased risk for infections due to an altered immune system and treatment with immunosuppressive medications. The aim of this study was to assess the prevalence of severe pneumococcal disease [SPD] and evaluate the impact of pneumococcal vaccination on the risk of SPD in Veterans with IBD. METHODS: Subjects with IBD and SPD were identified from the VA Health Administration database using ICD9/10 codes. Pneumococcal vaccination and use of immunosuppressant medications were collected. Risk of SPD was evaluated using an adjusted Cox proportional hazards model controlling for demographics, medications, vaccination, and comorbidities. RESULTS: A total of 1798 cases of SPD were identified [283 pneumonia, 1513 bacteraemia, and two meningitis]. SPD patients were older [60.9 years vs 59.4 years; p <0.001], had more comorbidities [Charlson Comorbidity Index of 2.11 vs 0.96; p <0.001], and had increased mortality [4.6% vs 1.5%, p <0.001]. The risk of SPD was increased in Crohn's disease (hazard ratio [HR] 1.15; 95% confidence interval [CI] 1.05-1.27) and with more comorbidities [HR 1.45; 95% CI 1.42-1.48]. Use of immunosuppressive medications increased the risk of SPD. Receipt of PCV13 either alone or in combination with PPSV23 predicted a 5-fold decreased risk of SPD compared with no vaccination. CONCLUSIONS: Risk factors for severe pneumococcal disease include having Crohn's disease, more comorbidities, and exposure to combination immunosuppression. Vaccination with PCV13 alone or in combination with PPSV23 and revaccination with PPSV23, was protective against SPD. All IBD patients should be evaluated for pneumococcal vaccination, particularly those receiving or expected to receive immunosuppressive therapies.

OBJECTIVE: To evaluate the impact of pre-intensive care unit admission (pre-ICU) statin use on all-cause in-hospital mortality and ICU length of stay (LOS). DESIGN: Retrospective cohort study. SETTING: Adult ICUs at tertiary hospitals. PATIENTS: Adult critically ill patients diagnosed with sepsis admitted to the ICUs. INTERVENTION: The exposure was pre-ICU statin prescription (statin users); unexposed represented absence of pre-ICU prescription (non-users). MEASUREMENT AND MAIN RESULTS: We used the 2001-2012 Medical Information Mart for Intensive Care-III (MIMIC-III) database to determine average treatment effect (ATE) of pre-ICU statin use on 30-day ICU mortality, ICU LOS, and 30-day in-hospital mortality using the Augmented Inverse Propensity Weighted technique (AIPW), after adjusting for confounding factors (age, race, health insurance, corticosteroids use, vital signs, laboratory tests, and Sequential Organ Failure Assessment score (SOFA). We measured 30-day ICU mortality as deaths within 30 days of admission to the ICU, and ICU LOS was measured in fractional days. A 30-day in-hospital mortality was measured as death within 30 days of hospital admission. A total of 8200 patients with sepsis were identified; 19.8% (1623) were statin users, and 80.2% (6577) were non-users. Most were Caucasian, aged 80 years and above, and male. After adjusting for confounding factors, pre-ICU statin use decreased 30-day ICU mortality (ATE, -0.026; 95% confidence interval [CI], -0.048 to -0.009); ICU LOS (ATE, -0.369; 95% Cl, -0.849 to -0.096); and 30-day in-hospital mortality (ATE, -0.039; 95% CI, -0.084 to -0.026) on average compared with non-statin use, respectively. In a stratified analysis, the result for ICU LOS (ATE, -0.526; 95% CI, -0.879 to -0.241) and 30-day in-hospital mortality (ATE, -0.023; 95% CI, -0.048 to -0.002) was consistent among patients admitted to the medical ICU. CONCLUSIONS: Among patients with sepsis admitted to the medical ICU, pre-ICU statin use is causally associated with a decrease in 30-day ICU mortality, ICU LOS, and 30-day in-hospital mortality compared to non-use. This study adds to the totality of evidence on the pleiotropic effect of statin use in patients with sepsis.

RESUMEN
BACKGROUND: The introduction of direct-acting antivirals (DAAs) represents a potential clinical cure for hepatitis C virus (HCV) infection. Identification of costs associated with different stages of untreated disease through cost-of-illness (COI) evaluation helps inform policy decisions and cost-effectiveness analyses (CEAs). This study's objective was to review published real-world costs for patients with HCV to estimate the COI across different stages of disease progression. METHODS: A literature search of EMBASE, Scopus, and PubMed from January 1, 2010 to August 31, 2019 was conducted to identify real-world evidence related to HCV. Data extraction included citation details, population, study type, costing method used, currency and inflation adjustments, and disease-specific costs. Standardized costing method categories (sum all medical, sum diagnosis specific, matching, regression, other incremental, and other total) were assigned. The risk of bias was assessed at the outcome level for influence on costs attributable to HCV. RESULTS: The search strategy identified 278 studies, with 31 included in the final review after inclusion and exclusion criteria were applied. Retrospective cohorts (77%) and cross-sectional analyses (16%) were most frequently encountered. Sum Diagnosis Specific was the most common costing method (39%), followed by Regression (32%). Of the 31 studies analyzed, 35% included costs that would be included in a societal model. Costs were identified for various stages and complications related to HCV disease progression. Several studies included were determined to have a high (48%) or moderate risk (42%) of bias related to COI estimates. CONCLUSION: Cost estimates for formal, informal, and non-health care services were identified in this review, but several challenges still exist in fully quantifying HCV burden. Future modeling studies including cost inputs should critically evaluate the risk of bias based on costing methods and data sources.

BACKGROUND: Cost-effectiveness evaluations for hepatitis C virus (HCV) treatments have been published frequently, but new products with significant cost and effectiveness differences make these analyses obsolete. How valuable are economic models for a fixed time period in a dynamic market? OBJECTIVE: To estimate the cost-effectiveness of the best available HCV treatment at different points in time, using the same comparator to demonstrate how rapid innovation in a disease area influences economic outcomes. METHODS: A Markov model was used to calculate the cost-effectiveness of treatment in 2010, 2012, 2014, 2016, and 2018 compared with a standard comparator (no treatment) from the payer perspective. Expected drug costs and treatment effectiveness estimates for sustained virologic response (SVR) were calculated using recommended regimens for each of the 6 HCV genotypes at each time point and distribution of genotypes in the United States. Patients entered the model with different stages of fibrosis. Utility estimates for each health state were used to calculate quality-adjusted life-years (QALYs) earned at each cycle. Incremental cost-effectiveness ratios were reported for each year to compare the "treatment versus no treatment" decision at that time. RESULTS: No HCV treatment resulted in a gain of 11.54 QALYs over a 20-year time horizon at a cost of $42,938. Costs for treated groups were $69,075, $123,267, $125,431, $86,782, and $56,470 for the 2010, 2012, 2014, 2016, and 2018 scenarios, respectively. QALYs gained for treated groups were 12.90, 12.97, 13.34, 13.39, and 13.46 for the 2010, 2012, 2014, 2016, and 2018 scenarios, respectively. The incremental cost-effectiveness ratios in each year compared with no treatment were $19,218 per QALY, $56,104 per QALY, $45,829 per QALY, $23,699 per QALY, and $7,048 per QALY. CONCLUSIONS: Treatment effectiveness for HCV has increased steadily, while treatment costs increased substantially from 2010-2014 before decreasing to its lowest point in 2018. Thus, the dynamic nature of innovation creates the need for iterative cost-effectiveness analyses. DISCLOSURES: No outside funding supported this study. Mattingly reports unrelated consulting from the National Health Council, Bristol Myers Squibb, G&W Laboratories, Allergy and Asthma Foundation of American, and the Massachusetts Health Policy Commission.

BACKGROUND: Ras-related C3 botulinum substrate 1 (Rac1) is a member of the small molecule family Rho guanosine triphosphate (GTP)ases. Recent findings reveal epigenetic downregulation of Rac1 is a mechanism of depression. AIMS: The purpose of this study was to evaluate Rac1 as a therapeutic target for depression we examine the association between thiopurines, which inhibit Rac1, and the risk of depression among US veterans. METHODS: This study uses data spanning January 2000-May 2019, comparing thiopurine exposure (no exposure, less than one year, 1-2.9 years, 3-5 years, and greater than five years) in two separate cohorts, a rheumatoid arthritis cohort and inflammatory bowel disease cohort. We estimate the hazard of depression using a time dependent cox proportional hazards model. RESULTS: A total of 76,763 rheumatoid arthritis and 46,787 inflammatory bowel disease patients met all inclusion criteria. Patients exposed to thiopurines less than one year have a 27% (hazard ratio=1.272; 95% confidence interval=(1.038-1.559)) and 67% (hazard ratio=1.667 95% confidence interval=(1.501-1.850)) higher risk of depression in the rheumatoid arthritis and inflammatory bowel disease cohorts, respectively. In the inflammatory bowel disease cohort, we find the risk of depression is increased for up to five years of thiopurine exposure. CONCLUSION: These results provide evidence that Rac1 regulation is a viable therapeutic target for depression. Further research into therapeutics targeting Rac1 for the treatment of depression is warranted.

Over the past several decades, the incidence of early-onset colorectal cancer (EOCRC; in patients <50 years old) has increased at an alarming rate. Although robust and scientifically rigorous epidemiological studies have sifted out environmental elements linked to EOCRC, our knowledge of the causes and mechanisms of this disease is far from complete. Here, we highlight potential risk factors and putative mechanisms that drive EOCRC and suggest likely areas for fruitful research. In addition, we identify inconsistencies in the evidence implicating a strong effect of increased adiposity and suggest that certain behaviours (such as diet and stress) might place nonobese and otherwise healthy people at risk of this disease. Key risk factors are reviewed, including the global westernization of diets (usually involving a high intake of red and processed meats, high-fructose corn syrup and unhealthy cooking methods), stress, antibiotics, synthetic food dyes, monosodium glutamate, titanium dioxide, and physical inactivity and/or sedentary behaviour. The gut microbiota is probably at the crossroads of these risk factors and EOCRC. The time course of the disease and the fact that relevant exposures probably occur in childhood raise important methodological issues that are also discussed.

Social media is increasingly utilized as a resource in healthcare. We sought to identify perceptions of using social media as an educational tool among healthcare practitioners. An electronic survey was distributed to healthcare administrators, nurses, nurse practitioners, pharmacists, physicians, and physician assistants f hospital systems and affiliated health science schools in Georgia, Maryland, South Carolina, and Wisconsin. Survey questions evaluated respondents' use and views of social media for educational purposes and workplace accessibility using a Likert scale (1 = strongly disagree, 5 = strongly agree). Nurses (75%), pharmacists (11%), and administrators (7%) were the most frequent respondents. Facebook® (27%), Pinterest® (17%), and Instagram® (17%) were the most frequently accessed social media platforms. Nearly 85% agreed or strongly agreed that social media can be an effective tool for educational purposes. Among those who had social media platforms, 43.0% use them for educational purposes. Pinterest® (30%), Facebook® (22%), LinkedIn® (16%), and Twitter® (14%) were most frequently used for education. About 50% of respondents had limited or no access to social media at work. Administrators, those with unlimited and limited work access, and respondents aged 20-29 and 30-39 years were more likely to agree that social media is an educational tool (OR: 3.41 (95% CI 1.31 to 8.84), 4.18 (95% CI 2.30 to 7.60), 1.66 (95% CI 1.22 to 2.25), 4.40 (95% CI 2.80 to 6.92), 2.14 (95% CI 1.53 to 3.01) respectively). Residents, physicians, and those with unlimited access were less likely to agree with allowing social media access at work for educational purposes only. Healthcare practitioners frequently utilize social media, and many believe it can be an effective educational tool in healthcare.

Hepatitis B virus (HBV) is a global disease with significant morbidity and mortality. Worldwide, ~257 million people are chronically infected with HBV, defined as having a positive hepatitis B surface antigen, but millions more have prior HBV exposure indicated by positive hepatitis B core antibody. Reactivation of hepatitis B implies a sudden increase in viral replication in a patient with chronic HBV infection or prior HBV exposure. Hepatitis B virus reactivation (HBVr) can occur spontaneously, but it is more commonly triggered by immunosuppressive therapies for cancer, immunologic diseases, or transplantation. Elimination of hepatitis C virus (HCV) in HBV-HCV coinfected individuals treated with direct-acting antivirals (DAAs) has also been identified as an important cause of HBVr. Hepatitis B virus reactivation is an underappreciated but important complication of common medical therapies that can delay treatment or result in clinical episodes of hepatitis, hepatic failure, or death. In this review, factors associated with HBVr, particularly medication-related risks, are explored. We review data involving rituximab and ofatumumab, doxorubicin, corticosteroids, tumor necrosis factor antagonists, tyrosine kinases, bortezomib, hematologic stem cell transplantation, and DAAs for HCV treatment. In addition, we discuss screening strategies, choice of antiviral prophylaxis, and the optimal duration of therapy for HBVr. With additional awareness, screening, and appropriate antiviral therapy, it is expected that most cases of HBVr can be prevented.
