Medicaid Medical Costs Associated with Hypertension by Diabetes Status among Women in Alabama.

Though a high proportion of Medicaid population in Alabama are women, little is known about their economic burdens of diabetes and hypertension. We used Alabama Medicaid claims data of 16,107 female enrollees aged 19-64 years to estimate per-capita total annual medical costs of hypertension by diabetes status. Hypertension prevalence was 60.0% and 17.3% among those with and without diabetes. The estimated annual medical cost for enrollees with hypertension was $6,689 (in 2017 $), of which $2,369 was associated with having hypertension. The hypertension-associated excess costs were $2,646 and $2,378 for enrollees with and without diabetes. All subgroups such as Blacks and those with Charlson Comorbidity Index ≥ 1, had higher medical costs when they had a combination of hypertension and diabetes compared with having diabetes without hypertension. Hypertension and diabetes increased medical costs substantially, and the findings can inform decision makers about effective resource utilizations for prevention and treatment strategies.

Prevalence and medical expenditures of diabetes-related complications among adult Medicaid enrollees with diabetes in eight U.S. states.

AIMS: To estimate the prevalence and medical expenditures of diabetes-related complications (DRCs) among adult Medicaid enrollees with diabetes. METHODS: We estimated the prevalence and medical expenditures for 12 diabetes-related complications by Medicaid eligibility category (disability-based vs. non-disability-based) in eight states. We used generalized linear models with log link and gamma distribution to estimate the total per-person annual medical expenditures for DRCs, controlling for demographics, and other comorbidities. RESULTS: Among non-disability-based enrollees (NDBEs), 40.1% (in California) to 47.5% (in Oklahoma) had one or more DRCs, compared to 53.6% (in Alabama) to 64.8% (in Florida) among disability-based enrollees (DBEs). The most prevalent complication was neuropathy (16.1%-27.1% for NDBEs; 20.2%-30.4% for DBEs). Lower extremity amputation (<1% for both eligibilities) was the least prevalent complication. The costliest per-person complication was dialysis (per-person excess annual expenditure of $22,481-$41,298 for NDBEs; $23,569-$51,470 for DBEs in 2012 USD). Combining prevalence and per-person excess expenditures, the three costliest complications were nephropathy, heart failure, and ischemic heart disease (IHD) for DBEs, compared to neuropathy, nephropathy, and IHD for NDBEs. CONCLUSIONS: Our study provides data that can be used for assessing the health care resources needed for managing DRCs and evaluating cost-effectiveness of interventions to prevent and management DRCs.

Estimated number of eligible Part B beneficiaries for the medicare diabetes prevention program at the county level and by urban-rural classification.

INTRODUCTION: Diabetes imposes large health and financial burdens on Medicare beneficiaries. Type 2 diabetes can be prevented or delayed through lifestyle modification programs. In 2018, Medicare began to offer the Medicare Diabetes Prevention Program (MDPP), a lifestyle intervention, to eligible beneficiaries nationwide. The number of MDPP-eligible beneficiaries is not known, but this information is essential in efforts to expand the program and increase enrollment. This study aimed to estimate the number and spatial variation of MDPP-eligible Part B beneficiaries at the county level and by urban-rural classification. METHODS: Data from 2011-2016 National Health and Nutrition Examination Surveys and a survey-weighted logistic regression model were used to estimate proportions of prediabetes in the United States by sex, age, and race/ethnicity based on the MDPP eligibility criteria. The results from the predictive model were applied to 2015 Medicare Part B beneficiaries to estimate the number of MDPP-eligible beneficiaries. The National Center for Health Statistics' Urban-Rural Classification Scheme for Counties from 2013 were used to define urban and rural categories. RESULTS: An estimated 5.2 million (95% CI = 3.5-7.0 million) Part B beneficiaries were eligible for the MDPP. By state, estimates ranged from 13,000 (95% CI = 8,500-18,000) in Alaska to 469,000 (95% CI = 296,000-641,000) in California. There were 2,149 counties with ≤1,000 eligible beneficiaries and 11 with >25,000. Consistent with demographic patterns, urban counties had more eligible beneficiaries than rural counties. CONCLUSIONS: These estimates could be used to plan locations for new MDPPs and reach eligible Part B beneficiaries for enrollment.

Opioid dispensing among adult Medicaid enrollees by diabetes status.

OBJECTIVE: Diabetes disproportionately affects low-income individuals, many of whom are covered by Medicaid. Comorbidities and complications of diabetes can lead to chronic pain; however, little is known about opioid use patterns among Medicaid enrollees with diabetes. This study examined opioid dispensing among Medicaid enrollees by diabetes status. METHODS: Medicaid claims data from 2014 were used to examine opioid dispensing by diabetes status among 622,992 adult enrollees aged 19-64 years. A logistic model adjusting for demographics and comorbidities was used to examine the association between diabetes and opioid dispensing among enrollees. Analyses were completed in 2019. RESULTS: Overall, 61.6% of enrollees with diabetes filled at least one opioid prescription compared to 31.8% of enrollees without diabetes. A higher proportion of enrollees with diabetes had long-term opioid prescriptions (>90 days' supply) (with diabetes: 51.0% vs. without: 32.1%, p < .001). Characteristics of individual prescriptions, including daily morphine milligram equivalents (45.9 vs. 49.4), formulation (percent short-acting: 91.5% vs. 90.7%), and type of opioids (i.e. percent hydrocodone: 46.7 vs. 45.3), were similar for those with and without diabetes. After adjustment, enrollees with diabetes were 1.43 times more likely to receive an opioid prescription compared to those without (95% CI, 1.40-1.46). CONCLUSIONS: Medicaid enrollees with diabetes were prescribed opioids more frequently and were more likely to have longer opioid supply than enrollees without diabetes. For practitioners who care for patients with diabetes, aligning pain management approaches with evidence-based resources, like the CDC Guideline for Prescribing Opioids for Chronic Pain, can encourage safer opioid prescribing practices.

Uptake of hepatitis C screening, characteristics of patients tested, and intervention costs in the BEST-C study.

From December 2012 to March 2014, three randomized trials, each implementing a unique intervention in primary care settings (repeated mailing, an electronic health record best practice alert [BPA], and patient solicitation), evaluated hepatitis C virus (HCV) antibody testing, diagnosis, and costs for each of the interventions compared with standard-of-care testing. Multilevel multivariable models were used to estimate the adjusted risk ratio (aRR) for receiving an HCV antibody test, and costs were estimated using activity-based costing. The goal of this study was to estimate the effects of interventions conducted as part of the Birth-Cohort Evaluation to Advance Screening and Testing for Hepatitis C study on HCV testing and costs among persons of the 1945-1965 birth cohort (BC). Intervention resulted in substantially higher HCV testing rates compared with standard-of-care testing (26.9% versus 1.4% for repeated mailing, 30.9% versus 3.6% for BPA, and 63.5% versus 2.0% for patient solicitation) and significantly higher aRR for testing after controlling for sex, birth year, race, insurance type, and median household income (19.2 [95% confidence interval (CI), 9.7-38.2] for repeated mailing, 13.2 [95% CI, 3.6-48.6] for BPA, and 32.9 [95% CI, 19.3-56.1] for patient solicitation). The BPA intervention had the lowest incremental cost per completed test ($24 with fixed startup costs, $3 without) and also the lowest incremental cost per new case identified after omitting fixed startup costs ($1691). CONCLUSION: HCV testing interventions resulted in an increase in BC testing compared with standard-of-care testing but also increased costs. The effect size and incremental costs of BPA intervention (excluding startup costs) support more widespread adoption compared with the other interventions. (Hepatology 2017;65:44-53).

The cost-effectiveness, health benefits, and financial costs of new antiviral treatments for hepatitis C virus.

BACKGROUND: New hepatitis C virus (HCV) treatments deliver higher cure rates with fewer contraindications, increasing demand for treatment and healthcare costs. The cost-effectiveness of new treatments is unknown. METHODS: We conducted a microsimulation of guideline testing followed by alternative treatment regimens for HCV among the US population aged 20 and older to estimate cases identified, treated, sustained viral response, deaths, medical costs, quality-adjusted life-years (QALYs), and the incremental cost-effectiveness ratio (ICER) of different treatment options expressed as discounted lifetime costs and benefits from the healthcare perspective. RESULTS: Compared to treatment with pegylated interferon and ribavirin (PR), and a protease inhibitor for HCV genotype (G) 1 and PR alone for G2/3, treatment with PR and Sofosbuvir (PRS) for G1/4 and treatment with Sofosbuvir and ribavirin (SR) for G2/3 increased QALYs by 555 226, reduced deaths by 80 682, and increased costs by $26.2 billion at an ICER of $47 304 per QALY gained. As compared to PRS/SR, treating with an all oral regimen of Sofosbuvir and Simeprevir (SS) for G1/4 and SR for G2/3, increased QALYs by 1 110 451 and reduced deaths by an additional 164 540 at an incremental cost of $80.1 billion and an ICER of $72 169. In sensitivity analysis, where treatment with SS effectiveness was set to the list price of Viekira Pak and then Harvoni, treatment cost $24 921 and $25 405 per QALY gained as compared to PRS/SR. CONCLUSIONS: New treatments are cost-effectiveness per person treated, but pent-up demand for treatment may create challenges for financing.

Effectiveness of a risk screener in identifying hepatitis C virus in a primary care setting.

OBJECTIVES: We evaluated an intervention designed to identify patients at risk for hepatitis C virus (HCV) through a risk screener used by primary care providers. METHODS: A clinical reminder sticker prompted physicians at 3 urban clinics to screen patients for 12 risk factors and order HCV testing if any risks were present. Risk factor data were collected from the sticker; demographic and testing data were extracted from electronic medical records. We used the t test, χ(2) test, and rank-sum test to compare patients who had and had not been screened and developed an analytic model to identify the incremental value of each element of the screener. RESULTS: Among screened patients, 27.8% (n = 902) were identified as having at least 1 risk factor. Of screened patients with risk factors, 55.4% (n = 500) were tested for HCV. Our analysis showed that 7 elements (injection drug use, intranasal drug use, elevated alanine aminotransferase, transfusions before 1992, ≥ 20 lifetime sex partners, maternal HCV, existing liver disease) accounted for all HCV infections identified. CONCLUSIONS: A brief risk screener with a paper-based clinical reminder was effective in increasing HCV testing in a primary care setting.

Primary care-based interventions are associated with increases in hepatitis C virus testing for patients at risk.

BACKGROUND: An estimated 3.2 million persons are chronically infected with the hepatitis C virus (HCV) in the U.S. Effective treatment is available, but approximately 50% of patients are not aware that they are infected. Optimal testing strategies have not been described. METHODS: The Hepatitis C Assessment and Testing Project (HepCAT) was a serial cross-sectional evaluation of two community-based interventions designed to increase HCV testing in urban primary care clinics in comparison with a baseline period. The first intervention (risk-based screener) prompted physicians to order HCV tests based on the presence of HCV-related risks. The second intervention (birth cohort) prompted physicians to order HCV tests on all patients born within a high-prevalence birth cohort (1945-1964). The study was conducted at three primary care clinics in the Bronx, New York. RESULTS: Both interventions were associated with an increased proportion of patients tested for HCV from 6.0% at baseline to 13.1% during the risk-based screener period (P<0.001) and 9.9% during the birth cohort period (P<0.001). CONCLUSIONS: Two simple clinical reminder interventions were associated with significantly increased HCV testing rates. Our findings suggest that HCV screening programs, using either a risk-based or birth cohort strategy, should be adopted in primary care settings so that HCV-infected patients may benefit from antiviral treatment.

The cost-effectiveness of birth-cohort screening for hepatitis C antibody in U.S. primary care settings.

BACKGROUND: In the United States, hepatitis C virus (HCV) infection is most prevalent among adults born from 1945 through 1965, and approximately 50% to 75% of infected adults are unaware of their infection. OBJECTIVE: To estimate the cost-effectiveness of birth-cohort screening. DESIGN: Cost-effectiveness simulation. DATA SOURCES: National Health and Nutrition Examination Survey, U.S. Census, Medicare reimbursement schedule, and published sources. TARGET POPULATION: Adults born from 1945 through 1965 with 1 or more visits to a primary care provider annually. TIME HORIZON: Lifetime. PERSPECTIVE: Societal, health care. INTERVENTION: One-time antibody test of 1945-1965 birth cohort. OUTCOME MEASURES: Numbers of cases that were identified and treated and that achieved a sustained viral response; liver disease and death from HCV; medical and productivity costs; quality-adjusted life-years (QALYs); incremental cost-effectiveness ratio (ICER). RESULTS OF BASE-CASE ANALYSIS: Compared with the status quo, birth-cohort screening identified 808,580 additional cases of chronic HCV infection at a screening cost of $2874 per case identified. Assuming that birth-cohort screening was followed by pegylated interferon and ribavirin (PEG-IFN+R) for treated patients, screening increased QALYs by 348,800 and costs by $5.5 billion, for an ICER of $15,700 per QALY gained. Assuming that birth-cohort screening was followed by direct-acting antiviral plus PEG-IFN+R treatment for treated patients, screening increased QALYs by 532,200 and costs by $19.0 billion, for an ICER of $35,700 per QALY saved. RESULTS OF SENSITIVITY ANALYSIS: The ICER of birth-cohort screening was most sensitive to sustained viral response of antiviral therapy, the cost of therapy, the discount rate, and the QALY losses assigned to disease states. LIMITATION: Empirical data on screening and direct-acting antiviral treatment in real-world clinical settings are scarce. CONCLUSION: Birth-cohort screening for HCV in primary care settings was cost-effective. PRIMARY FUNDING SOURCE: Division of Viral Hepatitis, Centers for Disease Control and Prevention.

Models of community-based hepatitis B surface antigen screening programs in the U.S. and their estimated outcomes and costs.

OBJECTIVES: Information on the process and method of service delivery is sparse for hepatitis B surface antigen (HBsAg) testing, and no systematic study has evaluated the relative effectiveness or cost-effectiveness of different HBsAg screening models. To address this need, we compared five specific community-based screening programs. METHODS: We funded five HBsAg screening programs to collect information on their design, costs, and outcomes of participants during a six-month observation period. We categorized programs into four types of models. For each model, we calculated the number screened, the number screened as per Centers for Disease Control and Prevention (CDC) recommendations, and the cost per screening. RESULTS: The models varied by cost per person screened and total number of people screened, but they did not differ meaningfully in the proportion of people screened following CDC recommendations, the proportion of those screened who tested positive, or the proportion of those who newly tested positive. CONCLUSIONS: Integrating screening into outpatient service settings is the most cost-effective method but may not reach all people needing to be screened. Future research should examine cost-effective methods that expand the reach of screening into communities in outpatient settings.

HCV screening practices and prevalence in an MCO, 2000-2007.

BACKGROUND/OBJECTIVE: The Centers for Disease Control and Prevention recommends routine screening for the hepatitis C virus antibody (anti- HCV) among persons most likely to be infected. Little is known about anti-HCV screening and prevalence in routine practice settings. We studied anti-HCV screening rates, anti-HCV positivity, and demographic and risk factors associated with increased likelihood of anti-HCV screening or positivity in a managed care organization (MCO). METHODS: This was a retrospective observational study of 17-to-74-year-old MCO enrollees from 2000 to 2007 (N = 557,056; 1,949,499 enrollee years). The primary outcome measures were likelihood of anti-HCV screening and HCV positivity (both in the total population and among those screened). Independent variables were: birth cohort, gender, HCV risk factors, and socioeconomic status (SES) and race of residents' neighborhoods. Likelihood of each outcome as a function of the independent variables was estimated using logistic regression. RESULTS: Over the 8-year period, 4.31% of the total population received anti-HCV screening; 0.22% had a positive HCV result. Among those screened, HCV positivity was 5.15%. HCV screening and positivity rates increased over time. Both likelihood of HCV screening and HCV positivity were highest (P <0.05) among persons born during 1945-1964, males, those with HCV risk factors, and residents of neighborhoods of lower SES or with higher percentages of African Americans. CONCLUSIONS: Although HCV screening and detection improved in this MCO over an 8-year period, anti-HCV screening was lower than expected. Many persons at risk for HCV remained unscreened. Strategies for improving anti-HCV screening in routine practice are recommended for patients at increased risk.

Forecasting the morbidity and mortality associated with prevalent cases of pre-cirrhotic chronic hepatitis C in the United States.

BACKGROUND: Without diagnosis and antiviral therapy, many patients with chronic hepatitis C infections will develop end-stage liver disease and die from complications. AIMS: To evaluate the future impacts of preventive interventions and treatment advances, this paper forecasts a baseline estimate of the future morbidity and mortality of prevalent hepatitis C when left untreated. METHODS: We simulated the future disease progression and death for all Americans with prevalent hepatitis C in 2005. To validate the model, we used past seroprevalence to forecast contemporary outcomes. We used the validated model to forecast future cases of end-stage liver disease, transplants, and deaths from 2010 to 2060, and we estimated credible intervals using Monte Carlo simulation. RESULTS: When programmed with past data, our model predicted current levels of hepatitis C outcomes with accuracy between ±1% and 13%. Morbidity and mortality from hepatitis C will rise from 2010 to a peak between the years 2030 and 2035. We forecasted a peak of 38,600 incident cases of end-stage liver disease; 3200 referrals for transplant; and 36,100 deaths. CONCLUSIONS: Because current rates of screening and treatment are low, future morbidity and mortality from hepatitis C are likely to increase substantially without public health interventions to increase treatment.

Ethnomedical syndromes and treatment-seeking behavior among Mayan refugees in Chiapas, Mexico.

This survey investigated the prevalence of ethnomedical syndromes and examined treatments and treatment-seeking in Mayan Guatemalans living in United Nations High Commissioner for Refugee (UNHCR) camps in Chiapas, Mexico. Methods included a rapid ethnographic assessment to refine survey methods and inform the cross-sectional survey, which also examined mental health outcomes; 183 households were approached for interview, representing an estimated 1,546 residents in five refugee camps and 93% of all households. One adult per household (N = 170) was interviewed regarding his or her health; an additional 9 adults in three surveyed households participated and were included in this analysis; of the 179 participants, 95 primary child-care providers also answered a children's health questionnaire for their children. Results indicated that ethnomedical syndromes were common in this sample, with 59% of adults and 48.4% of children having experienced susto (fright condition) and 34.1% of adults reporting ataques de nervios (nervous attacks); both conditions were significantly associated with symptoms consistent with posttraumatic stress disorder, anxiety and depression and are mental health conditions recognized by the American Psychiatric Association. Combining healthcare provider and indigenous treatments such as physician prescribed medication (65%), medicinal plants (65.7%), and limpias (spiritual cleansings) (40.6%) was reported. Most participants (86%) sought routine medical treatment from UNHCR trained health promoters in their camp. Assessing ethnomedical health is important for informing mental health programs among this population.
