The health equity implications of the Health Resources and Services Administration's Ryan White HIV/AIDS Program.

OBJECTIVE: Investigate the role of the Ryan White HIV/AIDS Program (RWHAP) - which funds services for vulnerable and historically disadvantaged populations with HIV - in reducing health inequities among people with HIV over a 10-year horizon. DESIGN: We use an agent-based microsimulation model to incorporate the complexity of the program and long-time horizon. METHODS: We use a composite measure (the Theil index) to evaluate the health equity implications of the RWHAP for each of four subgroups (based on race and ethnicity, age, gender, and HIV transmission category) and two outcomes (probability of being in care and treatment and probability of being virally suppressed). We compare results with the RWHAP fully funded versus a counterfactual scenario, in which the medical and support services funded by the RWHAP are not available. RESULTS: The model indicates the RWHAP will improve health equity across all demographic subgroups and outcomes over a 10-year horizon. In Year 10, the Theil index for race and ethnicity is 99% lower for both outcomes under the RWHAP compared to the non-RWHAP scenario; 71-93% lower across HIV transmission categories; 31-44% lower for age; and 73-75% lower for gender. CONCLUSION: Given the large number of people served by the RWHAP and our findings on its impact on equity, the RWHAP represents an important vehicle for achieving the health equity goals of the National HIV/AIDS Strategy (2022-2025) and the Ending the HIV Epidemic Initiative goal of reducing new infections by 90% by 2030.

Overall survival associated with CDK4/6 inhibitors in patients with HR+/HER2- metastatic breast cancer in the United States: A SEER-Medicare population-based study.

BACKGROUND: Evidence on overall survival (OS) with cyclin-dependent kinase 4 and 6 (CDK4/6) inhibitors is generally limited to data from clinical trials or a few observational studies with limited generalizability to Medicare population. The aim of this study was to determine OS benefits associated with CDK4/6 inhibitors in older Medicare patients with hormone receptor (HR)-positive and human epidermal growth factor receptor-2 overexpressing (HER2-) metastatic breast cancer (MBC). METHODS: In a retrospective cohort design, female patients aged ≥65 years with diagnosis of HR+/HER2- MBC from 2015 to 2017 who initiated first-line systemic therapy within 12 months of MBC diagnosis were selected from the Survey Epidemiology and End Results-Medicare database. The effect of treatment type (endocrine therapy [ET]+CDK4/6 inhibitor vs. ET alone) on OS was analyzed using Kaplan-Meier methods and multivariable Cox regression models. Adjusted hazard ratio (aHR) and 95% CIs were estimated. RESULTS: A total of 630 eligible patients were identified (169 patients treated with ET+CDK4/6 inhibitor and 461 patients treated with ET alone). In the Kaplan-Meier analysis, OS rate at 3 years after first-line treatment initiation was 73.0% for ET+CDK4/6 inhibitor versus 49.1% for ET alone (log-rank p < .0001). In Cox regression analysis, first-line ET+CDK4/6 inhibitor therapy was associated with 41% lower rate of mortality versus ET alone (aHR, 0.590; 95% CI, 0.423-0.823). CONCLUSIONS: The findings of this real-world study demonstrate significant OS benefit associated with ET+CDK4/6 inhibitor therapy over ET alone in an older Medicare population of patients with HR+/HER2- MBC, largely consistent with the evidence from clinical trials.

Impact of CDK4/6 inhibitors on chemotherapy utilization in earlier therapy lines for HR+/HER2- metastatic breast cancer in the United States.

PURPOSE: Delaying chemotherapy remains a vital goal in therapeutic management of HR+/HER2- metastatic breast cancer (MBC). However, recent reports continue to highlight substantially high chemotherapy utilization in earlier therapy lines. In this study, we explored the impact of cyclin-dependent kinase 4 and 6 (CDK4/6) inhibitor therapy class, introduced in 2015, on early chemotherapy utilization in an older population of patients with HR+/HER2- MBC in the United States (US). METHODS: Using an interrupted time series design, patients with a confirmed diagnosis of MBC aged ≥ 65 years initiating systemic therapy during 2010-2019 were selected from the SEER-Medicare database. The proportion of chemotherapy use was summarized quarterly based on the date of treatment initiation separately in the first, second, and third lines. Segmented regression models adjusted for autocorrelation over time were fitted to estimate trends before and after the availability of CDK4/6 inhibitors in the first quarter of 2015. RESULTS: Of the 3244 eligible women (median age at diagnosis: 74 years), all initiated first-line therapy; 47.9% (n = 1581) initiated second-line therapy, and 50.1% (n = 792) initiated third-line therapy. Overall utilization of chemotherapy (alone or in combination) during the study period was 15.7% for the first line, 19.6% for the second line, and 24.8% for the third line. Chemotherapy utilization in the period immediately after introduction of CDK4/6 inhibitor therapy decline by estimated 2.5% in the first line (P = 0.408), 15.5% in the second line (P = 0.005), and 16.3% in the third line (P = 0.003). CONCLUSIONS: This population-based study illustrates that chemotherapy utilization in earlier therapy lines for HR+/HER2- MBC declined steadily between 2010 and 2019. These declines were significantly accelerated by the introduction of CDK4/6 therapy class in 2015, notably in the second- and third-line settings.

Assessment of Therapeutic Response of Edaravone and Riluzole Combination Therapy in Amyotrophic Lateral Sclerosis Patients.

Background: Amyotrophic lateral sclerosis (ALS) is a progressive disease characterized by chronic degeneration of upper and lower motor neurons and finally death within 3-5 years usually because of respiratory failure. Riluzole and edaravone are presently available treatments. It may be better to try combination therapy rather than taking individual medications. Objectives: To compare the effectiveness of (edaravone + riluzole) combination therapy versus riluzole therapy alone in slowing down the progression of ALS and to evaluate the role of serum creatinine as a marker of disease progression. Materials and Methods: Observational, randomized, parallel assignment, open label study. Thirty patients with definite and probable ALS were randomly assigned to two treatment groups. The case group received (riluzole + edaravone) for the initial 6 months, followed by riluzole for the next 6 months. The control group received riluzole for 12 months. After 6 and 12 months, changes in ALS functional rating scale (ALSFRS-R), mRS, and Japanese ALS scores were determined. P value <.05 was considered significant. Results: An increase in mRS at 6 months in the case group versus control group was 0.07 versus 0.20, respectively (p =0.02). At 12 months, it was 0.47 versus 0.53, respectively (p =0.17). A decrease in serum creatinine at 6 months in case group versus control group was 0.08 versus 0.09, respectively (p =.82). There was no change in ALS FRS for bulbar symptoms (salivation), 3.46 versus 3.46 in the case group (p =.018) for the first 6 months. Conclusions: Combined with riluzole, edaravone slows disease progression and is safe, but the effect is short-term. Bulbar symptoms respond better to combination therapy. The serum creatinine is helpful in monitoring disease progression.

Use of oral anticoagulants among individuals with cancer and atrial fibrillation in the United States, 2010-2016.

BACKGROUND: Anticoagulation among patients with cancer and atrial fibrillation is challenging due to elevated risk of bleeding and stroke. We characterized use of oral anticoagulants among patients with cancer and non-valvular atrial fibrillation (NVAF). METHODS: We used Surveillance, Epidemiology, and End Results (SEER)-Medicare data and included patients with cancer aged ≥66 years with an incident diagnosis of NVAF from 2010 to 2016. We used a Cox proportional hazard model and multivariable logistic regression to identify factors associated with anticoagulant use versus no use and direct oral anticoagulants (DOACs) versus warfarin use, respectively. RESULTS: Of 27,702 patients with cancer and NVAF, 4469 (16.1%) used DOACs and 3577 (12.9%) used warfarin. Among 8046 anticoagulant users, DOACs use increased from 21.8% in 2011 to 76.2% in 2016, with a corresponding decline in warfarin use from 78.2% to 23.8%. Nearly 7 out of 10 patients with cancer and NVAF did not initiate anticoagulation in 2016. Anticoagulant use was more likely among those with higher CHA2DS2-VASc scores (hazard ratio [HR] 1.55, 95% confidence interval [CI] 1.27-1.90 for score ≥6 vs. 1) or with lower HAS-BLED scores (HR 1.96, 95% CI 1.67-2.30 for score 1 vs. ≥6). Among anticoagulant users, DOAC use was less likely than warfarin in those with higher CHA2DS2-VASc scores (odds ratio [OR] 0.53, 95% CI 0.33-0.84 for score ≥6 vs. 1). CONCLUSIONS: Nearly 7 out of 10 patients with cancer and NVAF did not receive anticoagulation. Use of DOACs increased from 2010 to 2016, with a corresponding decline in warfarin use. DOACs are used less than warfarin among those at higher risk of stroke.

Real-world evidence on survival, adverse events, and health care burden in Medicare patients with mantle cell lymphoma.

Most data on overall survival (OS) and adverse events (AEs) in patients with mantle cell lymphoma (MCL) are from controlled trials; therefore, in this population-based study, we retrospectively assessed treatment patterns, OS, and AEs in MCL patients initiating systemic treatment during 2013-2015 using the United States Medicare claims database. Among 1390 eligible patients (median age = 74 years), chemoimmunotherapy with bendamustine/rituximab (BR) was the preferred choice in first-line (35.3%), followed by ibrutinib (33.5%), rituximab (9.1%), and rituximab/cyclophosphamide/doxorubicin/vincristine (R-CHOP) (6.8%). Twenty-four-month OS was 73% for BR; 47%, ibrutinib; 72%, rituximab; and 71%, R-CHOP. For the four most commonly used regimens, neutropenia, anemia, hypertension, and infection were the most frequent AEs. Patients with ≥3 AEs had nearly four times higher monthly costs than those with 0-2 AEs in the first observed therapy line. Findings demonstrate a substantial increase in the economic burden as the number of AEs increased among the Medicare MCL patients.

Overall survival, adverse events, and economic burden in patients with chronic lymphocytic leukemia receiving systemic therapy: Real-world evidence from the medicare population.

BACKGROUND: Information on overall survival (OS) and adverse events (AEs) in patients with chronic lymphocytic leukemia (CLL) is mostly available from clinical trials. We therefore conducted a population-based retrospective cohort study to assess OS, incidence of AEs, and economic burden in real-world practice among Medicare patients treated for CLL. METHODS: Patients with CLL receiving ≥1 systemic therapy from 2013 to 2015 were selected from the Medicare claims database and followed from the start of first observed systemic therapy (index date) through December 2016 or death. OS for patients receiving each of the most commonly observed treatments was estimated by the Kaplan-Meier method. AEs were assessed among patients receiving these treatments across all observed lines of therapy. All-cause direct medical costs were assessed from the Medicare system perspective. RESULTS: Among 7,965 eligible patients across all observed therapy lines, ibrutinib monotherapy (Ibr; n = 2,708), chlorambucil monotherapy (Clb; n = 1,620), and bendamustine/rituximab (BR; n = 1,485) were the most common treatments. For first observed therapy, 24-month OS estimates for Ibr, Clb, and BR recipients were 69% (95% CI = 68%-71%), 68% (95% CI = 65%-71%), and 79% (95% CI = 77%-81%) respectively. The most frequently recorded AEs in patients receiving these treatments in any observed line of therapy were neutropenia, hypertension, anemia, and infection. For all patients, the mean monthly all-cause cost during the follow-up period was $8,974 (SD = $11,562); cost increased by the number of AEs, from $5,144 (SD = $5,409) among those with 1-2 AEs to $10,077 (SD = $12,542) among those with ≥6 AEs. CONCLUSION: Over two-thirds of patients survived at least 2 years after starting their first observed therapy for CLL. Our findings highlight considerable susceptibility to AEs and unmet medical need in Medicare patients with CLL treated in routine practice. Medicare incurred substantial economic burden following initiation of systemic therapy, and patients with greater numbers of AEs accounted disproportionately for the high overall cost of CLL management.

Treatment patterns, adverse events, and direct and indirect economic burden in a privately insured population of patients with HR+/HER2- metastatic breast cancer in the United States.

BACKGROUND: Real-world evidence specific to HR+/HER2- metastatic breast cancer (MBC) prior to introduction of CDK4/6 inhibitors is limited. In an effort to provide context for the introduction of new treatments, we assessed treatment patterns, adverse events, productivity loss, and direct/indirect economic burden in a privately insured population of patients with HR+/HER2- MBC. RESEARCH DESIGN AND METHODS: Using a retrospective cohort design, patients aged 18-64 years, selected from MarketScan databases (2007-2014), were analyzed using descriptive and multivariable methods. RESULTS: Among 5,563 eligible patients, endocrine therapy was the most common first-line (1L) therapy; its utilization trended downward from 63% (1L) to 23% (4L), with a simultaneous increase in chemotherapy use, 25% (1L) to 50% (4L). Two hundred and seventy-eight unique treatment regimens were used in the 1L setting. The average per patient monthly all-cause costs were $14,424. The 12-month indirect costs for short-term disability were substantially higher in MBC patients ($10,397) than in matched noncancer patients ($394). CONCLUSION: The increasing use of chemotherapy as patients progressed to second and later lines and the substantial direct/indirect economic burden underscore an unmet need. The high number of 1L regimens highlights significant heterogeneity and a lack of consensus related to the management of HR+/HER2- MBC in routine practice.

Cost-Effectiveness of HRSA's Ryan White HIV/AIDS Program?

BACKGROUND: With an annual budget of more than $2 billion, the Health Resources and Services Administration's Ryan White HIV/AIDS Program (RWHAP) is the third largest source of public funding for HIV care and treatment in the United States, yet little analysis has been done to quantify the long-term public health and economic impacts of the federal program. METHODS: Using an agent-based, stochastic model, we estimated health care costs and outcomes over a 50-year period in the presence of the RWHAP relative to those expected to prevail if the comprehensive and integrated system of medical and support services funded by the RWHAP were not available. We made a conservative assumption that, in the absence of the RWHAP, only uninsured clients would lose access to these medical and support services. RESULTS: The model predicts that the proportion of people with HIV who are virally suppressed would be 25.2 percentage points higher in the presence of the RWHAP (82.6 percent versus 57.4 percent without the RWHAP). The number of new HIV infections would be 18 percent (190,197) lower, the number of deaths among people with HIV would be 31 percent (267,886) lower, the number of quality-adjusted life years would be 2.7 percent (5.6 million) higher, and the cumulative health care costs would be 25 percent ($165 billion) higher in the presence of the RWHAP relative to the counterfactual. Based on these results, the RWHAP has an incremental cost-effectiveness ratio of $29,573 per quality-adjusted life year gained compared with the non-RWHAP scenario. Sensitivity analysis indicates that the probability of transmitting HIV via male-to-male sexual contact and the cost of antiretroviral medications have the largest effect on the cost-effectiveness of the program. CONCLUSIONS: The RWHAP would be considered very cost-effective when using standard guidelines of less than the per capita gross domestic product of the United States. The results suggest that the RWHAP plays a critical and cost-effective role in the United States' public health response to the HIV epidemic.

Development of a Mathematical Model to Estimate the Cost-Effectiveness of HRSA's Ryan White HIV/AIDS Program.

BACKGROUND: The Health Resources and Services Administration's Ryan White HIV/AIDS Program provides services to more than half of all people diagnosed with HIV in the United States. We present and validate a mathematical model that can be used to estimate the long-term public health and cost impact of the federal program. METHODS: We developed a stochastic, agent-based model that reflects the current HIV epidemic in the United States. The model simulates everyone's progression along the HIV care continuum, using 2 network-based mechanisms for HIV transmission: injection drug use and sexual contact. To test the validity of the model, we calculated HIV incidence, mortality, life expectancy, and lifetime care costs and compared the results with external benchmarks. RESULTS: The estimated HIV incidence rate for men who have sex with men (502 per 100,000 person years), mortality rate of all people diagnosed with HIV (1663 per 100,000 person years), average life expectancy for individuals with low CD4 counts not on antiretroviral therapy (1.52-3.78 years), and lifetime costs ($362,385) all met our validity criterion of within 15% of external benchmarks. CONCLUSIONS: The model represents a complex HIV care delivery system rather than a single intervention, which required developing solutions to several challenges, such as calculating need for and receipt of multiple services and estimating their impact on care retention and viral suppression. Our strategies to address these methodological challenges produced a valid model for assessing the cost-effectiveness of the Ryan White HIV/AIDS Program.

Treatment patterns, adverse events, and economic burden in a privately insured population of patients with chronic lymphocytic leukemia in the United States.

INTRODUCTION: Contemporary data describing treatment patterns, adverse events (AEs), and outcomes in patients with chronic lymphocytic leukemia (CLL) in clinical practice are lacking. We conducted a retrospective cohort study and assessed treatment patterns, AEs, health-care resource use (HCRU), and costs in patients with diagnosis of CLL. METHODS: Using a nationally representative population of privately insured patients in the US, adult patients with CLL diagnosis (July 2012-June 2015) were selected if they had continuous health plan enrollment for ≥12 months before the first CLL diagnosis without any evidence of any CLL-directed treatment. Treatment patterns up to four lines of therapy (LOT) and occurrence of AEs during CLL therapies were assessed. Mean per-patient monthly HCRU and costs were assessed overall and by number of unique AEs. RESULTS: Of all patients meeting the selection criteria (n = 7,639; median age, 66 years), 18% (n = 1,379) received a systemic therapy during study follow-up. Of these, bendamustine/rituximab (BR) was the most common first observed regimen (28.1%), while ibrutinib was the most common therapy in the second (20.8%) and third (25.5%) observed regimens. The mean monthly all-cause and CLL-related costs, among patients treated with a systemic therapy, were $7,943 (SD = $15,757) and $5,185 (SD = $9,935), respectively. Mean monthly all-cause costs increased by the number of AEs (from $905 [SD = $1,865] among those with no AEs to $6,032 [SD = $13,290] among those with ≥6 AEs). CONCLUSIONS: Chemoimmunotherapy, particularly BR, was the most common first observed therapy for CLL, whereas ibrutinib was most preferred in the second and third observed lines of therapy during the study period. Findings demonstrate that the economic burden of AEs in CLL is substantial.

Treatment patterns, survival and economic outcomes in Medicare-enrolled, older patients with HR+/HER2- metastatic breast cancer.

Background: Endocrine therapy (ET) remains a foundation of systemic therapy for HR+/ HER2- metastatic breast cancer (MBC), although chemotherapy (CT) is used in select patients. In this "real-world" study, we explored treatment patterns, health care resource use (HCRU), costs, adverse events (AEs) and overall survival (OS) in Medicare-enrolled, older patients with HR+/HER2- MBC. Methods: Patients with HR+/HER2- MBC (2007-2011) and aged >66 years were retrospectively analyzed using the SEER-Medicare data. Treatment patterns, HCRU, costs, AEs and OS after MBC diagnosis through end of study period (31 December 2013) were examined using descriptive and multivariable analyses. Results: Among 3622 eligible patients, ET was the most common treatment (77%), followed by CT (50%), radiation (48%) and surgery (19%). The proportion of patients treated with ET monotherapy decreased across therapy lines, from 74% in first line (1 L) to 35% in 4 L. The total number of unique therapy regimens used was 181 in 1 L, 171 in 2 L, 128 in 3 L, and 95 in 4 L. The median OS from MBC diagnosis was 25.3 months (95% CI, 24.0-26.7). In multivariable analyses, receipt of CT and combination CT + ET (versus ET monotherapy) in 1 L, metastatic disease at initial diagnosis, larger tumor size, and presence of visceral and brain metastases at MBC diagnosis significantly predicted receipt of 2 L therapy. Conclusions: ET was the most common first-line treatment for study patients, but its use decreased gradually in the subsequent lines. The heterogeneity in the treatment selection highlights a lack of consensus for the management of HR+/HER2- MBC in routine practice.

Adverse events, resource use, and economic burden associated with mantle cell lymphoma: a real-world assessment of privately insured patients in the United States.

In view of recent therapeutic advances in mantle cell lymphoma (MCL), the aim of this retrospective cohort analysis was to assess treatment patterns, adverse events (AEs), resource utilization, and health care costs in patients with MCL in a US-based commercial claims database. A total of 783 patients with MCL (median age = 65 years) were selected. Among patients receiving systemic therapy (n = 457), the most common treatment regimens were bendamustine/rituximab (BR) (41.1%), rituximab/cyclophosphamide/doxorubicin/vincristine (RCHOP) (26.7%), rituximab monotherapy (20.4%), and ibrutinib monotherapy (14.2%). Mean monthly costs during treatments with BR, RCHOP, rituximab, and ibrutinib were $12,958, $24,719, $13,153, and $21,690, respectively. Mean monthly cost during follow-up was $13,650 among patients with ≥6 AEs versus $5131 among those without AEs. The costs of MCL varied considerably by treatment regimen and care setting. The overall economic burden of managing patients with MCL can be substantially affected by costs associated with managing AEs occurring during treatment.

Time trends in utilization of G-CSF prophylaxis and risk of febrile neutropenia in a Medicare population receiving adjuvant chemotherapy for early-stage breast cancer.

PURPOSE: The purpose of this study is to assess temporal trends in the use of granulocyte colony-stimulating factor (G-CSF) prophylaxis and risk of febrile neutropenia (FN) among older women receiving adjuvant chemotherapy for early-stage breast cancer. METHODS: Women aged ≥ 66 years with diagnosis of early-stage breast cancer who initiated selected adjuvant chemotherapy regimens were identified using the SEER-Medicare data from 2002 to 2012. Adjusted, calendar-year-specific proportions were estimated for use of G-CSF primary prophylaxis (PP) and secondary prophylaxis and FN risk in the first and the second/subsequent cycles during the first course of chemotherapy, using logistic regression models. calendar-year-specific mean probabilities were estimated with covariates set to modal values. RESULTS: Among 11,107 eligible patients (mean age 71.7 years), 74% received G-CSF in the first course of chemotherapy. Of all patients, 5819 (52%) received G-CSF PP, and among those not receiving G-CSF PP, only 5% received G-CSF secondary prophylaxis. The adjusted proportion using G-CSF PP increased from 6% in 2002 to 71% in 2012. During the same period, the adjusted risk of FN in the first cycle increased from 2% to 3%; the adjusted risk increased from 1.5% to 2.9% among those receiving G-CSF PP and from 2.3% to 3.5% among those not receiving G-CSF PP. CONCLUSION: The use of G-CSF PP increased substantially during the study period. Although channeling of higher-risk patients to treatment with G-CSF PP is expected, the adjusted risk of FN among patients treated with G-CSF PP tended to be lower than among those not receiving G-CSF PP.

Does Maternity Care Coordination Influence Perinatal Health Care Utilization? Evidence from North Carolina.

OBJECTIVE: To examine effects of maternity care coordination (MCC) on perinatal health care utilization among low-income women. DATA SOURCES: North Carolina Center for Health Statistics Baby Love files that include birth certificates, maternity care coordination records, WIC records, and Medicaid claims. STUDY DESIGN: Causal effects of MCC participation on health care outcomes were estimated in a sample of 7,124 singleton Medicaid-covered births using multiple linear regressions with inverse probability of treatment weighting (IPTW). PRINCIPAL FINDINGS: Maternity care coordination recipients were more likely to receive first-trimester prenatal care (p < .01) and averaged three more prenatal visits and two additional primary care visits during pregnancy; they were also more likely to participate in WIC and to receive postpartum family planning services (p < .01). Medicaid expenditures were greater among mothers receiving MCC. CONCLUSIONS: Maternity care coordination facilitates access to health care and supportive services among Medicaid-covered women. Increased maternal service utilization may increase expenditures in the short run; however, improved newborn health may reduce the need for costly neonatal care, and by implication the need for early intervention and other supports for at-risk children.

Association between medical home enrollment and health care utilization and costs among breast cancer patients in a state Medicaid program.

BACKGROUND: The patient-centered medical home (PCMH) is increasingly being implemented in an effort to improve and coordinate primary care, but its effect on health care utilization among breast cancer patients remains unclear. The objective of this study was to examine health care utilization and expenditures as a function of PCMH enrollment among breast cancer patients in North Carolina's Medicaid program. METHODS: North Carolina Medicaid claims linked to North Carolina Central Cancer Registry records (2003-2007) were used to examine monthly patterns of health care use and expenditures. Controlling for a selection bias for time-invariant characteristics, fixed effects regression models analyzed associations between PCMH enrollment and utilization of outpatient, inpatient, and emergency department (ED) services and Medicaid expenditures during the 15 months after the diagnosis of breast cancer. RESULTS: Among 758 breast cancer patients, 381 (50%) were enrolled in a PCMH at some time in the 15 months after diagnosis. After controlling for individual fixed effects, PCMH enrollment was significantly associated with greater outpatient service use, but there was no difference in the probability of inpatient hospitalizations or ED visits. Enrollment in a PCMH was associated with increased average expenditures of $429 per month during the first 15 months. CONCLUSIONS: Greater outpatient care utilization and increased average expenditures among breast cancer patients enrolled in a PCMH may suggest that these women have improved access to primary and specialty care. Expanding PCMHs may change patterns of service utilization for Medicaid breast cancer patients but may not be associated with lower costs.

Health and human rights in eastern Myanmar after the political transition: a population-based assessment using multistaged household cluster sampling.

BACKGROUND: Myanmar transitioned to a nominally civilian parliamentary government in March 2011. Qualitative reports suggest that exposure to violence and displacement has declined while international assistance for health services has increased. An assessment of the impact of these changes on the health and human rights situation has not been published. METHODS AND FINDINGS: Five community-based organizations conducted household surveys using two-stage cluster sampling in five states in eastern Myanmar from July 2013-September 2013. Data was collected from 6, 178 households on demographics, mortality, health outcomes, water and sanitation, food security and nutrition, malaria, and human rights violations (HRV). Among children aged 6-59 months screened, the prevalence of global acute malnutrition (representing moderate or severe malnutrition) was 11.3% (8.0-14.7). A total of 250 deaths occurred during the year prior to the survey. Infant deaths accounted for 64 of these (IMR 94.2; 95% CI 66.5-133.5) and there were 94 child deaths (U5MR 141.9; 95% CI 94.8-189.0). 10.7% of households (95% CI 7.0-14.5) experienced at least one HRV in the past year, while four percent reported 2 or more HRVs. Household exposure to one or more HRVs was associated with moderate-severe malnutrition among children (14.9 vs. 6.8%; prevalence ratio 2.2, 95% CI 1.2-4.2). Household exposure to HRVs was associated with self-reported fair or poor health status among respondents (PR 1.3; 95% CI 1.1-1.5). CONCLUSION: This large survey of health and human rights demonstrates that two years after political transition, vulnerable populations of eastern Myanmar are less likely to experience human rights violations compared to previous surveys. However, access to health services remains constrained, and risk of disease and death remains higher than the country as a whole. Efforts to address these poor health indicators should prioritize support for populations that remain outside the scope of most formal government and donor programs.

Changes in North Carolina maternal health service use and outcomes among medicaid-enrolled pregnant women during state budget cuts.

OBJECTIVES: The recent recession has weakened the US health and human service safety net. Questions about implications for mothers and children prompted this study, which tested for changes in maternal service use and outcomes among North Carolina women with deliveries covered through Medicaid before and after a year of significant state budget cuts. METHODS: Data for Medicaid covered deliveries from April-June 2009 (pre) and from April-June 2010 (post) were derived from birth certificates, Medicaid claims and eligibility files, and WIC (Special Supplemental Food Program for Women, Infants and Children) records. These time periods represent the quarter immediately before as well as the final quarter of a state fiscal year 2010 (July 2009-June 2010) characterized by substantial state budget cuts, including an October 2009 reduction in reimbursement rates for maternity care coordination. We examined how often women received medical care, maternity care coordination, family planning services, and the average numbers of obstetrical encounters, as well as the prevalence of excessive pregnancy weight gain, preterm delivery, and low birth weight. RESULTS: By the end of a year of substantial state budget cuts, women covered through Medicaid had fewer obstetrical visits in all trimesters as well as postpartum (P < .001). Maternal weight gain, preterm delivery, and low birth weight were stable. CONCLUSIONS: One key aspect of medical service use decreased for women enrolled in Medicaid by the end of a year of major state health and human services budget cuts. Maternal and infant child health outcomes measured in this study did not change during that year. Future monitoring is warranted to ensure that maternal health service access remains adequate.

Real-world treatment patterns and costs in a US Medicare population with metastatic squamous non-small cell lung cancer.

OBJECTIVES: Despite advances in the treatment of nonsquamous non-small cell lung cancer (NSCLC), therapeutic choices and overall disease course for squamous NSCLC have remained relatively unchanged over the past several years. We provide a detailed account of current treatment patterns, healthcare use, and survival in real-world clinical settings for metastatic squamous NSCLC. MATERIALS AND METHODS: Patients aged ≥65 years with metastatic squamous NSCLC diagnosed 2001-2009 were identified and followed through 2010 using the Surveillance, Epidemiology and End Results-Medicare database. Treatment patterns were descriptively analyzed. Multivariate logistic regressions were estimated to identify predictors of treatment pattern events; generalized linear models were estimated for total all-cause and NSCLC-related costs to assess cost drivers. RESULTS: Of 17,133 patients, 72% received cancer-directed therapy (surgery, radiation, chemotherapy, or biologic therapy), whereas 28% received only supportive care. Median survival was significantly longer in patients receiving cancer-directed therapy (8 months) than in patients receiving supportive care only (2 months) (P<0.0001). An agent-specific first-line chemotherapy regimen was identified for 91% of the 7700 patients who received chemotherapy. Among these, the most common first-line regimen was carboplatin-paclitaxel combination therapy (46%). Common second-line regimens were gemcitabine monotherapy (16%) and pemetrexed monotherapy (11%). Factors associated with decreased odds of receiving cancer-directed treatment were black versus white race (OR, 0.72; 95% CI, 0.64-0.82), residence in the West versus South (OR, 0.73; 95% CI, 0.66-0.81), and metastatic disease at initial diagnosis versus progression to metastatic disease (OR, 0.77; 95% CI, 0.70-0.84). CONCLUSIONS: Our study shows that prognosis remains poor for patients with metastatic squamous NSCLC, even among those receiving treatment, but particularly for patients limited to supportive care only, highlighting the continuing unmet medical need in this population. Additionally, our analysis indicates that selections for second-line and third-line chemotherapies are not necessarily consistent with National Comprehensive Cancer Network guidelines.

Effects of maternity care coordination on pregnancy outcomes: propensity-weighted analyses.

Care coordination services that link pregnant women to health-promoting resources, avoid duplication of effort, and improve communication between families and providers have been endorsed as a strategy for reducing disparities in adverse pregnancy outcomes, however empirical evidence regarding the effects of these services is contradictory and incomplete. This study investigates the effects of maternity care coordination (MCC) on pregnancy outcomes in North Carolina. Birth certificate and Medicaid claims data were analyzed for 7,124 women delivering live infants in North Carolina from October 2008 through September 2010, of whom 2,255 received MCC services. Propensity-weighted analyses were conducted to reduce the influence of selection bias in evaluating program participation. Sensitivity analyses compared these results to conventional ordinary least squares analyses. The unadjusted preterm birth rate was lower among women who received MCC services (7.0 % compared to 8.3 % among controls). Propensity-weighted analyses demonstrated that women receiving services had a 1.8 % point reduction in preterm birth risk; p < 0.05). MCC services were also associated with lower pregnancy weight gain (p = 0.10). No effects of MCC were seen for birthweight. These findings suggest that coordination of care in pregnancy can significantly reduce the risk of preterm delivery among Medicaid-enrolled women. Further research evaluating specific components of care coordination services and their effects on preterm birth risk among racial/ethnic and geographic subgroups of Medicaid enrolled mothers could inform efforts to reduce disparities in pregnancy outcome.
