Shah D, Shah A, Tan X, Sambamoorthi U. Trends in utilization of smoking cessation agents before and after the passage of FDA boxed warning in the United States. Drug Alcohol Depend 2017; 177:187-193. [PMID: 28605678 PMCID: PMC5568118 DOI: 10.1016/j.drugalcdep.2017.03.021] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2016] [Revised: 03/08/2017] [Accepted: 03/14/2017] [Indexed: 10/19/2022]
Abstract
BACKGROUND In 2009, the FDA required a black box warning (BBW) on bupropion and varenicline, the two commonly prescribed smoking cessation agents due to reports of adverse neuropsychiatric events. We investigated if there was a decline in use of bupropion and varenicline after the BBW by comparing the percent using these medications before and after BBW. METHODS We conducted a retrospective observational study using data from the Medical Expenditure Panel Survey from 2007 to 2014. The study sample consisted of adult smokers, who were advised by their physicians to quit smoking. We divided the time period into "pre-warning", "post-warning: immediate", and "post-warning: late." Unadjusted analysis using chi-square tests and adjusted analyses using logistic regressions were conducted to evaluate the change in bupropion and varenicline use before and after the BBW. Secondary analyses using piecewise regression were also conducted. RESULTS On an average, 49.04% of smokers were advised by their physicians to quit smoking. We observed a statistically significant decline in varenicline use from 22.1% in year 2007 to 9.23% in 2014 (p value<0.001). In the logistic (Adjusted Odds Ratio=0.36, 95% CI=0.22-0.58) and piecewise regressions (Odds Ratio=0.64, 95% CI=0.41-0.99) smokers who were advised to quit smoking by their physicians were less likely to use varenicline in the immediate post-BBW period as compared to pre-BBW period. While the use of varenicline continued to be significantly low in the late post-BBW period (AOR=0.45, 95% CI=0.31-0.64) as compared to the pre-BBW period, the trend in use as seen in piecewise regression remained stable (OR=0.90, 95% CI=0.75-1.06). We did not observe significant differences in bupropion use between the pre- and post-BBW periods. CONCLUSION The passage of the FDA boxed warning was associated with a significant decline in the use of varenicline, but not in the use of bupropion.

Abstract
BACKGROUND Fibromyalgia, a potentially debilitating chronic pain syndrome of unknown etiology, may be characterized by inflammation. In this study, we investigated the relation of FMS to serum C-reactive protein (CRP) in a large population of adults (18+) and investigated the influence of other factors on this relationship, including BMI, comorbidities, as well as mood and sleep disturbance. METHODS Participants were 52,535 Ohio Valley residents (Fibromyalgia n = 1125). All participants completed a comprehensive health survey (2005-2006) part of the C8 Health Project; serum levels of CRP were obtained, as was history of Fibromyalgia physician diagnosis. Logistic and linear regressions were used for this cross-sectional analysis. RESULTS Mean CRP was higher among participants reporting Fibromyalgia than those without (5.54 ± 9.8 vs.3.75 ± 7.2 mg/L, p < .0001)). CRP level showed a strong, positive association with FMS (unadjusted odds ratio (OR) for highest vs. lowest quartile = 2.5 (CI 2.1,3.0;p for trend < .0001)); adjustment for demographic and lifestyle factors attenuated but did not eliminate this association (AOR for highest vs. lowest quartile = 1.4 (CI 1.1,1.6;p for trend < .0001)). Further addition of body mass index (BMI) and comorbidities to the model markedly weakened this relationship (AORs, respectively, for highest vs lowest CRP quartile = 1.2 (CI 1.0,1.4) and 1.1 (CI 0.9,1.3). In contrast, inclusion of mood and sleep impairment only modestly reduced the adjusted risk estimate (AORs for highest vs. lowest quartile = 1.3 (CI 1.1,1.5) for each)). CONCLUSIONS Findings from this large cross-sectional study indicate a significant positive cross-sectional association of Fibromyalgia to serum C-reactive protein may be explained, in part, by BMI and comorbidity. Prospective research is needed to confirm this, and clarify the potential mediating influence of obesity and comorbid conditions on this relationship.

Abstract
The purpose of this study is to explore the associations between polypharmacy and multimorbidity using conventional and novel measures of polypharmacy. In this cross-sectional study, data on fee-for-service (FFS) Medicaid enrollees with at least 1 chronic condition and aged 18-64 years (N = 38,329) were derived from the 2010 Medicaid Analytic eXtract (MAX) files of Maryland and West Virginia. Polypharmacy, by the authors' novel definition, was determined as simultaneous use of ≥5 drugs for a consecutive period of 60 days. Multimorbidity was defined as having ≥2 chronic conditions based on the US Department of Health and Human Services framework. The association between multimorbidity and polypharmacy was examined with chi-square tests and logistic regression. Polypharmacy prevalence was estimated at 50.9% using the novel definition, as compared to 16.7% and 64.9% for the 2 commonly used conventional measures, respectively. For all 3 definitions, individuals with multimorbidity were more likely to have polypharmacy than those without multimorbidity (P < 0.001). The authors also consistently found, using all definitions, that those who were older, female, white, and eligible for Medicaid because of cash assistance were more likely to have polypharmacy (all P < 0.001). Polypharmacy was highly prevalent and significantly associated with multimorbidity among Medicaid FFS enrollees irrespective of the definitions used. The new measure may provide a more comprehensive and accurate estimation of polypharmacy than the conventional measures. These findings suggest the need for a paradigm shift from disease-specific care to patient-centered collaborative care to manage patients with multimorbidity and polypharmacy.

Abstract
OBJECTIVE To examine the persistence with rapid-acting insulin (RAI) and its association with clinical outcomes among elderly patients with type 2 diabetes (T2D). METHODS This observational, retrospective cohort study analyzed RAI persistence and its association with change in glycated hemoglobin A1c and risk of severe hypoglycemia among elderly (≥65 years) Medicare beneficiaries with T2D who added RAI to their basal insulin regimen. RESULTS Among T2D patients with >1 RAI prescriptions (n = 3927), only 21% were persistent. Baseline factors positively associated with RAI persistence (adjusted odds ratio [95% CI]) were: age ≥75 vs. 65-74 years: 1.20 (1.01-1.43); use of ≥3 oral antidiabetes drugs: 1.63 (1.16-2.28); cognitive impairment: 1.34 (1.03-1.73); and A1C >9.0%: 1.58 (1.15-2.17). Elderly T2D patients having emergency department visits (0.73 [0.59-0.91]) and higher RAI out-of-pocket costs (≥$75 vs. $0 - <$6.40: 0.56 [0.44-0.70]) were less likely to be persistent. Persistent RAI users had a significantly higher reduction in A1C (beta coefficient [standard error]): -0.24 (0.10) and lower odds of severe hypoglycemia (adjusted odds ratio [95% CI]): 0.73 (0.53-0.99). CONCLUSION Among elderly T2D patients, persistence with RAI added to basal insulin was associated with improved glycemic control and lower risk of severe hypoglycemia. Despite treatment effectiveness, RAI persistence was poor and might be improved by reducing RAI out-of-pocket costs.

Abstract
BACKGROUND West Virginia (WV) residents are at high risk for polypharmacy given its considerable chronic disease burdens. OBJECTIVE To evaluate the prevalence, correlates, outcomes, and geographic variations of polypharmacy among WV Medicaid beneficiaries. METHODS In this cross-sectional study, we analyzed 2009-2010 WV Medicaid fee-for-service (FFS) claims data for adults aged 18-64 (N=37,570). We defined polypharmacy as simultaneous use of drugs from five or more different drug classes on a daily basis for at least 60 consecutive days in one year. Multilevel logistic regression was used to explore the individual- and county-level factors associated with polypharmacy. Its relationship with healthcare utilization was assessed using negative binomial regression and logistic regression. The univariate local indicators of spatial association method was applied to explore spatial patterns of polypharmacy in WV. RESULTS The prevalence of polypharmacy among WV Medicaid beneficiaries was 44.6%. High-high clusters of polypharmacy were identified in southern WV, indicating counties with above-average prevalence surrounded by counties with above-average prevalence. Polypharmacy was associated with being older, female, eligible for Medicaid due to cash assistance or medical eligibility, having any chronic conditions or more chronic conditions, and living in a county with lower levels of education. Polypharmacy was associated with more hospitalizations, emergency department visits, and outpatient visits, as well as higher non-drug medical expenditures. CONCLUSIONS Polypharmacy was prevalent among WV Medicaid beneficiaries and was associated with substantial healthcare utilization and expenditures. The clustering of high prevalence of polypharmacy in southern WV may suggest targeted strategies to reduce polypharmacy burden in these areas.

J Am Dent Assoc 2017; 148:500-509.e4. [PMID: 28483048 DOI: 10.1016/j.adaj.2017.03.012] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2016] [Revised: 03/20/2017] [Accepted: 03/21/2017] [Indexed: 12/16/2022]
Abstract
BACKGROUND Sugar-sweetened beverages (SSBs) are dietary sources of sugar that are factors in caries development and tooth loss. Dietary sugar also is linked to diabetes mellitus (DM). There is limited research related to SSBs and tooth loss in people with DM. The authors investigated the association between SSBs and tooth loss as it related to the presence or absence of DM. METHODS The authors used a cross-sectional design with data reported by adults (18 years and older) who responded to the 2012 Behavior Risk Factor Surveillance System questionnaire, which was used in 18 states (N = 95,897; 14,043 who had DM and 81,854 who did not have DM). The authors conducted χ2 and logistic regression analyses to determine associations related to DM status. RESULTS Overall, 12.3% of the survey respondents had DM, 15.5% had 6 or more teeth extracted, and 22.6% reported that they consumed 1 or more SSB daily. In the adjusted analyses, among adults who had DM, those who consumed at least 2 SSBs daily were more likely to have had 6 or more teeth extracted than those who reported that they did not consume SSBs (adjusted odds ratio, 2.35; 95% confidence interval, 1.37 to 4.01; P = .0018). Among adults who did not have DM, those who consumed more than 1 but fewer than 2 SSBs per day were more likely to have had at least 6 teeth extracted (adjusted odds ratio, 1.46; 95% confidence interval, 1.21 to 1.77; P < .0001). CONCLUSIONS The authors found that, among adults with DM, consuming 2 or more SSBs per day was associated with having had 6 or more teeth extracted. PRACTICAL IMPLICATIONS Dietary sugar is a concern for oral and systemic health; however, a strong, independent relationship between the number of teeth extracted and a single source of dietary sugar is not adequate to explain the complexity of tooth loss. Clinicians should use broadly worded dietary messages when discussing caries assessment with patients.

Abstract
Background: Differences in Medicare expenditures during the initial phase of cancer care among rural and medically underserved elderly women with breast cancer (BC) and those from a nationally representative cohort have not been reported. The objective of this study was to determine Medicare expenditures during the initial phase of care among women in West Virginia (WV) who were Medicare beneficiaries with BC and compare them with national estimates. The magnitude of differences in these expenditures was also determined by using a linear decomposition technique. Methods: A retrospective observational study was conducted using the WV Cancer Registry-Medicare database and the SEER-Medicare database. Our study cohorts consisted of elderly women aged ≥66 years diagnosed with incident BC in 2003 to 2006. Medicare expenditures during the initial year after BC diagnosis were derived from all of the Medicare files. Generalized linear regressions were performed to model expenditures, after controlling for predisposing factors, enabling resources, need, healthcare use, and external healthcare environmental factors. Blinder-Oaxaca decomposition was conducted to examine the proportion of the differences in the average expenditures explained by independent variables included in the model. Results: Average Medicare expenditures for the WV Medicare cohort during the initial phase of BC care were $25,626 compared with $29,502 for the SEER-Medicare cohort; a difference of $3,876. In the multivariate regression, this difference decreased to $708 and remained significant. Only 16% of the differences in the average expenditures between the cohorts were explained by the independent variables included in the model. Enabling resources (6.86%), healthcare use (7.55%), and external healthcare environmental factors (3.33%) constituted most of the explained portion of the differences in the average expenditures. Conclusions: The difference in average Medicare expenditures between the elderly beneficiaries with BC from a rural state (WV) and their national counterparts narrowed but remained significantly lower after multivariate adjustment. The explained portion of this difference was mainly driven by enabling and healthcare use factors, whereas 84% of this difference remained unexplained.

Abstract
OBJECTIVE Depression treatment can improve the health outcomes of elderly cancer survivors. There is a paucity of studies on the extent to which depression is treated among elderly cancer survivors. Therefore, this study estimated the rates of depression treatment among elderly cancer survivors and identified the factors affecting depression treatment. METHODS A retrospective cohort study design was adopted, and data were obtained from the linked Surveillance, Epidemiology and End Results (SEER) and Medicare database. Elderly individuals (≥ 66 years) with incident cases of breast, colorectal, or prostate cancer and newly diagnosed depression (N=1,673) were followed for six months after the depression diagnosis to identify depression treatment (antidepressants only, psychotherapy only, combined treatment with both antidepressants and psychotherapy, and no depression treatment). Chi-square tests and multinomial logistic regressions were used to analyze the factors associated with depression treatment. RESULTS In this study population, 46% received antidepressants only, 27% received no treatment, 18% received combined therapy, and 9% received psychotherapy only. Factors associated with depression treatment included anxiety, the percentage of psychologists at the county level, the number of visits to primary care physicians, ongoing cancer treatment, the presence of other chronic conditions, and race-ethnicity. CONCLUSIONS The study findings indicate that two-thirds of cancer survivors received depression treatment in the first six months after depression diagnosis. Our study findings indicate that racial-ethnic disparities in depression treatment persist and competing demands for cancer treatment may take priority over depression care. Also, the availability of psychologists may influence receipt of psychotherapy among cancer survivors.

Abstract
INTRODUCTION Care of individuals with Alzheimer's Disease and Related Dementias (ADRD) poses special challenges. As the disease progresses, individuals with ADRD require increasing levels of medical care, caregiver support, and long-term care which can lead to substantial economic burden. Areas covered: In this expert review, we synthesized findings from studies of costs of ADRD in the United States that were published between January 2006 and February 2017, highlighted major sources of variation in costs, identified knowledge gaps and briefly outlined directions for future research and implications for policy and program planning. Expert commentary: A consistent finding of all studies comparing individuals with and without ADRD is that the average medical, non-medical, and indirect costs of individuals with ADRD are higher than those without ADRD, despite the differences in the methods of identifying ADRD, duration of the study, payer type and settings of study population. The economic burden of ADRD may be underestimated because many components such as direct non-medical costs for home safety modifications and adult day care services and indirect costs due to the adverse impact of ADRD on caregivers' health and productivity are not included in cost estimates.

Abstract
BACKGROUND Although breast cancer is most prevalent among older women, the majority are diagnosed at an early stage. When diagnosed at an early stage, women have the option of breast-conserving surgery (BCS) plus radiation therapy (RT) or mastectomy for the treatment of early-stage breast cancer (ESBC). Omission of RT when receiving BCS increases the risk for recurrence and poor survival. Yet, a small subset of older women may omit RT after BCS. This study examines the current patterns of local treatment for ESBC among older women. METHODS This study conducted a retrospective observational analysis using the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked dataset of women age ≥66 diagnosed with stage I-II breast cancer in 2003-2009. SEER-Medicare data was additionally linked with data from the Area Resource File (ARF) to examine the association between area-level healthcare resources and treatment. Two logistic regression models were used to estimate how study factors were associated with receiving (1) BCS versus BCS+RT and (2) Mastectomy versus BCS+RT. A stratified analysis was also conducted among women aged <70 years. RESULTS Among 45,924 patients, 55% received BCS+RT, 23% received mastectomy, and 22% received BCS only. Women of increasing age, comorbidity, primary care provider visits, stage II disease, and nonwhite race were more likely to have mastectomy or BCS only, than BCS+RT. Women diagnosed in 2004-2006, treated by an oncology surgeon, residing in metro areas, areas of greater education and income, were less likely to receive mastectomy or BCS only, than BCS+RT. While women aged <70 years were more likely to receive BCS+RT, socioeconomic and physician specialties were associated with receiving BCS only. CONCLUSIONS Over half of older women with ESBC initially receive BCS+RT. The likelihood for mastectomy and BCS only increases with age, comorbidity, and vulnerable socio-demographic characteristics. Findings demonstrate continued treatment disparities among certain vulnerable populations.

Abstract
INTRODUCTION Arthritis and depression are two of the top disabling conditions. When arthritis and depression exist in the same individual, they can interact with each other negatively and pose a significant healthcare burden on the patients, their families, payers, healthcare systems, and society as a whole. Areas covered: The primary objective of this review is to summarize, identify knowledge gaps and discuss the challenges in estimating the healthcare burden of depression among individuals with arthritis. Electronic literature searches were performed on PubMed, Embase, EBSCOhost, Scopus, the Cochrane Library, and Google Scholar to identify relevant studies. Expert Commentary: Our review revealed that the prevalence of depression varied depending on the definition of depression, type of arthritis, tools and threshold points used to identify depression, and the country of residence. Depression exacerbated arthritis-related complications as well as pain and was associated with poor health-related quality of life, disability, mortality, and high financial burden. There were significant knowledge gaps in estimates of incident depression rates, depression attributable disability, and healthcare utilization, direct and indirect healthcare costs among individuals with arthritis.

Abstract
OBJECTIVE To estimate rates and patterns of depression treatment among adults with chronic obstructive pulmonary disease (COPD) and depression. METHODS We used a retrospective, cross-sectional study design, pooling data from 2010 and 2012 Medical Expenditure Panel Survey (MEPS). The study sample consisted of 527 individuals aged 21 years or older, diagnosed with COPD and depression. Depression treatment was grouped into three categories based on those who received: (1) neither antidepressant nor psychotherapy; (2) antidepressants only; and (3) psychotherapy combined with antidepressants (combination therapy). We conducted chi-squared tests and multinomial logistic regressions to examine factors (demographic, socio-economic characteristics, healthcare access, health status, and personal health practices) associated with depression treatment among adults with COPD and depression. KEY FINDINGS The mean age of the study sample was 55.96 years (SD = 13.36). Overall, 18.8% of the sample adults did not report any use of antidepressants or psychotherapy, 58.3% reported antidepressants use only and 23% reported using combination therapy. Females (adjusted odds ratio [AOR] = 1.89, 95% CI = 1.02, 3.55), older adults (≥65 years: AOR = 3.69, 95% CI = 1.62, 8.41), adults with fair/poor physical health status (AOR = 3.32, 95% CI = 1.29, 8.56) and those suffering from anxiety (AOR = 1.94, 95% CI = 1.09, 3.46) were more likely to receive antidepressant treatment. Older adults (AOR =2.94, 95% CI = 1.05, 8.22), those who were never married (AOR = 3.17, 95% CI = 1.18, 8.56), suffered from anxiety (AOR =6.01, 95% CI = 3.11, 11.61) and current smokers (AOR = 2.29, 95% CI = 1.05, 4.98) were more likely to receive combination therapy. Whereas, adults who were uninsured (AOR = 0.21, 95% CI = 0.05, 0.86) and did not lacked regular physical activity (AOR = 0.33, 95% CI = 0.16, 0.67) were less likely to receive combination therapy. A key limitation of our study is that we could not control for the severity of depression or COPD which may have influenced depression treatment. CONCLUSION Efforts to improve depression care among adults with co-occurring COPD and depression may need to be tailored for different subgroups.

OBJECTIVE Medications commonly used to treat heart disease, anxiety, and depression can interact resulting in an increased risk of bleeding, warranting a cautious approach in medical decision making. This retrospective, descriptive study examined the prevalence and the factors associated with the use of both selective-serotonin reuptake inhibitor and platelet aggregation inhibitor among individuals with co-occurring atherosclerotic cardiovascular disease and anxiety or depression. METHODS Respondents aged 22 years and older, alive throughout the study period, and diagnosed with co-occurring atherosclerotic cardiovascular disease and anxiety or depression (n = 1507) in years 2007 through 2013 of the Medical Expenditures Panel Survey were included. The use of treatment was grouped as follows: selective-serotonin reuptake inhibitor and platelet aggregation inhibitor, selective-serotonin reuptake inhibitor or platelet aggregation inhibitor, and neither selective-serotonin reuptake inhibitor nor platelet aggregation inhibitor. RESULTS Overall, 16.5% used both selective-serotonin reuptake inhibitor and platelet aggregation inhibitor, 61.2% used selective-serotonin reuptake inhibitor or platelet aggregation inhibitor, and 22.3% used neither selective-serotonin reuptake inhibitor nor platelet aggregation inhibitor. Respondents aged over 65 years (adjusted odds ratio = 1.93 (95% confidence interval = 1.08-3.45)) and having a diagnosis of diabetes (adjusted odds ratio = 1.63 (95% confidence interval = 1.15-2.31)) and hypertension (adjusted odds ratio = 1.84 (95% confidence interval = 1.04-3.27)) were more likely to be prescribed the combination. CONCLUSION The drug interaction was prevalent in patients who are already at higher risk of health disparities and worse outcomes thus requiring vigilant evaluation.

Abstract
OBJECTIVES There is considerable variation in dental services utilization across Appalachian counties, and a plausible explanation is that individuals in some geographical areas do not utilize dental care due to dental workforce shortage. We conducted an ecological study on dental workforce availability and dental services utilization in Appalachia. METHODS We derived county-level (n = 364) data on demographic and socioeconomic characteristics and dental services utilization in Appalachia from the 2010 Behavioral Risk Factor Surveillance System (BRFSS) using person-level data. We obtained county-level dental workforce availability and physician-to-population ratio estimates from Area Health Resources File and linked them to the county-level BRFSS data. The dependent variable was the proportion using dental services within the last year in each county (ranging from 16.6% to 91.0%). We described the association between dental workforce availability and dental services utilization using ordinary least squares regression and spatial regression techniques. Spatial analyses consisted of bivariate local indicators of spatial association (LISA) and geographically weighted regression (GWR). RESULTS Bivariate LISA showed that counties in the central and southern Appalachian regions had significant (P < 0.05) low-low spatial clusters (low dental workforce availability, low percent dental services utilization). GWR revealed considerable local variations in the association between dental utilization and dental workforce availability. In the multivariate GWR models, 8.5% (t-statistics > 1.96) and 13.45% (t-statistics > 1.96) of counties showed positive and statistically significant relationships between the dental services utilization and workforce availability of dentists and dental hygienists, respectively. CONCLUSIONS Dental workforce availability was associated with dental services utilization in the Appalachian region; however, this association was not statistically significant in all counties. The findings suggest that program and policy efforts to improve dental services utilization need to focus on factors other than increasing the dental workforce availability for many counties in Appalachia.

Abstract
Background Disease-modifying drugs are not yet available for the management of chronic obstructive pulmonary disease (COPD). HMG-CoA reductase inhibitors (statins) have anti-inflammatory properties and are therefore being considered for use in the management of COPD. Objective Our objective was to examine the association between statin use and COPD-specific outcomes in a real-world setting. Methods This was a retrospective longitudinal dynamic cohort study that used Medicaid claims data from multiple years (2005–2008) to identify patients with newly diagnosed COPD. Statin therapy was determined from the prescription drug file using National Drug Codes (NDCs). COPD-specific outcomes such as hospitalizations and emergency room and outpatient visits were identified based on a primary diagnosis of COPD. Multivariable logistic regressions with inverse probability treatment weights (IPTWs) were used to examine the relationship between statin therapy and COPD-specific outcomes. Results The study included 19,060 Medicaid beneficiaries with newly diagnosed COPD, 30.3% of whom received statins during the baseline period. Adults who received statins had significantly lower rates of COPD-specific hospitalizations (4.7 vs. 5.2%; p < 0.05), emergency room visits (13.4 vs. 15.4%; p < 0.001), and outpatient visits (41.4 vs. 44.7%; p < 0.001) than those who did not receive statin therapy. Even after adjusting for observed selection bias with IPTWs, adults receiving statins were less likely to have COPD-specific hospitalizations [adjusted odds ratio (AOR) 0.76; 95% confidence interval (CI) 0.66–0.87], emergency room visits (AOR 0.81; 95% CI 0.75–0.89), and outpatient visits (AOR 0.86; 95% CI 0.80–0.91) than those not receiving statins. Conclusions Findings from this study suggest statins have beneficial effects in patients with newly diagnosed COPD and warrant further clinical trial investigation.

Abstract
PURPOSE Worldwide, the number of disabled individuals is used as a marker for population health status because of high morbidity and mortality burden associated with disability. The primary objective of the current study is to use the 2012 NHIS disability supplement and examine racial/ethnic disparities in disability after controlling for a comprehensive list of factors, using the World Health Organization's International Classification of Functioning, Disability, and Health (WHO-ICF). METHODS A retrospective cross-sectional study design with data from 7993 individuals aged above 21 years from the 2012 National Health Interview Survey (NHIS) was adopted. Disability was defined based on a standard set of questions related to mobility, self-care, and cognition from the "Functioning and Disability" supplement of 2012 NHIS. Chi-squared tests and multinomial logistic regressions were conducted to examine the association between race/ethnicity and disability. RESULTS There were statistically significant racial/ethnic differences in disability status; 10.2 % non-Hispanic whites, 14.8 % non-Hispanic African Americans, 8.1 % Latino, and 6.7 % other racial minorities had severe disability. Non-Hispanic African Americans were more likely to have severe disability than were non-Hispanic whites (OR = 1.56, 95 % CI = 1.24, 1.95), and Latinos were less likely to have severe disability (OR = 0.70, 95 % CI = 0.55, 0.90) in the unadjusted model. There was no difference in disability status among non-Hispanic African Americans and non-Hispanic whites after adjusting for socio-economic status. CONCLUSION The study findings highlighted the role of socio-economic characteristics in reducing disparities in disability between non-Hispanic African Americans and non-Hispanic whites. As SES can affect health through a complex interaction of biological, psychological, lifestyle, environmental, social, and neighborhood factors, a multipronged approach that focuses on primary, secondary, and territory prevention of disability is needed.

Abstract
OBJECTIVES Depression is associated with high healthcare expenditures, and depression treatment may reduce healthcare expenditures. However, to date, there have not been any studies on the effect of depression treatment on healthcare expenditures among cancer survivors. Therefore, this study examined the association between depression treatment and healthcare expenditures among elderly with depression and incident cancer. METHODS The current study used a retrospective longitudinal study design, the linked Surveillance, Epidemiology, and End Results-Medicare database. Elderly (≥66 years) fee-for-service Medicare beneficiaries with newly diagnosed depression and incident breast, colorectal, or prostate cancer (N = 1502) were followed for a period of 12 months after depression diagnosis. Healthcare expenditures were measured every month for a period of 12-month follow-up period. Depression treatment was identified during the 6-month follow-up period. The adjusted associations between depression treatment and healthcare expenditures were analyzed with generalized linear mixed model regressions with gamma distribution and log link after controlling for other factors. RESULTS The average 1-year total healthcare expenditures after depression diagnosis were $38 219 for those who did not receive depression treatment; $42 090 for those treated with antidepressants only; $46 913 for those treated with psychotherapy only; and $51 008 for those treated with a combination of antidepressants and psychotherapy. As compared to no depression treatment, those who received antidepressants only, psychotherapy only, or a combination of antidepressants and psychotherapy had higher healthcare expenditures. However, second-year expenditures did not significantly differ among depression treatment categories. CONCLUSIONS Among cancer survivors with newly diagnosed depression, depression treatment did not have a significant effect on expenditures in the long term.

Abstract
OBJECTIVE Adults 65 years of age and older comprise the fastest growing demographic in the United States. As substance use is projected to increase in this population, there is concern that more seniors will drive under the influence of impairing drugs. The purpose of this analysis was to characterize the drug and alcohol usage among senior drivers fatally injured (FI) in traffic collisions. METHODS Data from the Fatality Analysis Reporting System were analyzed from 2008 to 2012. Commonly used classes and specific drugs were explored. Rates of drug use, multiple drugs, concomitant drug and alcohol use, and alcohol use alone were generated using Poisson regression with robust error variance estimation. Rates were compared to a reference population of FI middle-aged drivers (30 to 50 years old) using rate ratios. RESULTS Drug use among FI senior drivers occurred in 20.0% of those tested. Among drug-positive FI senior drivers, narcotics and depressants were frequent. The prevalence of testing positive for any drug, multiple drugs, combined drug and alcohol, and alcohol use alone among FI seniors were 47% less (relative risk [RR] = 0.53, 95% confidence interval [CI], 0.47, 0.62), 59% less (RR = 0.41, 95% CI, 0.34, 0.51), 87% less (RR = 0.13, 95% CI, 0.09, 0.19), and 77% less (RR = 0.23, 95% CI, 0.19, 0.28), respectively, compared to FI middle-aged drivers. CONCLUSIONS Though overall drug use is less common among FI senior drivers relative to FI middle-aged drivers, driving under the influence of drugs may be a relevant traffic safety concern in a portion of this population.

Abstract
OBJECTIVE The objective of this study was to examine the longitudinal patterns of emergency department (ED) visits among adult fee-for-service Medicaid. DATA SOURCES Data were obtained from the Medicaid analytic eXtract files, Area Health Resource File, and County Health Rankings. STUDY DESIGN A retrospective longitudinal study design, with four observations for each individual was used. The study population consisted of 33,393 Medicaid beneficiaries who met inclusion criteria. ED visits were time-lagged and time-varying patient-level factors were measured for each year. Time-invariant characteristics (gender and race/ethnicity) were measured in 2006. Multivariable hurdle models with logistic (ED use versus no ED use) and negative binomial regressions (ED visits among ED users) were used to analyze the ED visits over time. To account for correlation due to repeated observations, mixed effect models with robust standard errors were performed. PRINCIPAL FINDINGS In both unadjusted and adjusted analysis, the likelihood of ED use did not change from year to year (AOR = 1.00, 95 percent CI: 0.99, 1.01). Among ED users, the estimated number of ED visits increased over time (IRR = 1.01, 95 percent CI: 1.01, 1.03). CONCLUSIONS Primary care resources should be a major focus to reduce the increased burden on the EDs.

Abstract
A retrospective data analysis using 2000-2008 three state Medicaid Analytic eXtract was conducted to examine the prevalence and association of comorbidities (psychiatric and non-psychiatric) with healthcare utilization and expenditures of fee-for-service enrolled adults (22-64 years) with and without autism spectrum disorders (International Classification of Diseases, Ninth Revision-clinical modification code: 299.xx). Autism spectrum disorder cases were 1:3 matched to no autism spectrum disorder controls by age, gender, and race using propensity scores. Study outcomes were all-cause healthcare utilization (outpatient office visits, inpatient hospitalizations, emergency room, and prescription drug use) and associated healthcare expenditures. Bivariate analyses (chi-square tests and t-tests), multinomial logistic regressions (healthcare utilization), and generalized linear models with gamma distribution (expenditures) were used. Adults with autism spectrum disorders (n = 1772) had significantly higher rates of psychiatric comorbidity (81%), epilepsy (22%), infections (22%), skin disorders (21%), and hearing impairments (18%). Adults with autism spectrum disorders had higher mean annual outpatient office visits (32ASD vs 8noASD) and prescription drug use claims (51ASD vs 24noASD) as well as higher mean annual outpatient office visits (US$4375ASD vs US$824noASD), emergency room (US$15,929ASD vs US$2598noASD), prescription drug use (US$6067ASD vs US$3144noASD), and total expenditures (US$13,700ASD vs US$8560noASD). The presence of a psychiatric and a non-psychiatric comorbidity among adults with autism spectrum disorders increased the annual total expenditures by US$4952 and US$5084, respectively.

Abstract
Background. Effective communication and high trust with doctor are important to reduce the burden of multimorbidity in the rapidly aging population of the US. However, the association of multimorbidity with patient-doctor communication and trust is unknown. Objective. We examined the relationship between multimorbidity and patient-doctor communication and trust among the elderly. Method. We used the Medicare Current Beneficiary Survey (2012) to analyze the association between multimorbidity and patient-doctor communication and trust with multivariable logistic regressions that controlled for patient's sociodemographic characteristics, health status, and satisfaction with care. Results. Most elderly beneficiaries reported effective communication (87.5-97.5%) and high trust (95.4-99.1%) with their doctors. The elderly with chronic physical and mental conditions were less likely than those with only physical conditions to report effective communication with their doctor (Adjusted Odds Ratio [95% Confidence Interval] = 0.80 [0.68, 0.96]). Multimorbidity did not have a significant association with patient-doctor trust. Conclusions. Elderly beneficiaries had high trust in their doctors, which was not affected by the presence of multimorbidity. Elderly individuals who had a mental condition in addition to physical conditions were more likely to report ineffective communication. Programs to improve patient-doctor communication with patients having cooccurring chronic physical and mental health conditions may be needed.

Abstract
Use of multiple prescription medications is common among individuals with chronic obstructive pulmonary disease (COPD) because of coexisting inflammatory-related conditions. Specifically, the use of antidepressants, inhaled corticosteroids (ICSs), and statins may place individuals with COPD at high risk for new-onset diabetes. The objective was to examine the relationship between the use of antidepressants, ICSs, and statins and new-onset diabetes among Medicaid beneficiaries with COPD. This study used a retrospective longitudinal cohort design using multiple years (2005-2008) of Medicaid claims for beneficiaries with newly diagnosed COPD (n = 15,287), who were diabetes free at baseline. National Drug Codes were used to determine the receipt of antidepressants, ICSs, and statins, and International Classification of Diseases, Ninth Revision, Clinical Modification codes were used to define new-onset diabetes (250.x2). Multivariable logistic regression was used to examine the adjusted relationship between medication use and new-onset diabetes. Overall, 6.3% of the study population was diagnosed with new-onset diabetes. After controlling for baseline characteristics, individuals using ICSs (adjusted odds ratio [AOR]: 1.23; 95% confidence interval [CI]: 1.07, 1.47) or statins (AOR: 1.48; 95% CI: 1.27, 1.72) had a greater risk of new-onset diabetes compared to those not given ICSs, statins, or antidepressants. Analyses using combined medication categories revealed that adults using statins in combination with both antidepressants and ICSs, or when combined with ICS, were more likely to have new-onset diabetes. These findings indicate that multiple medication use (ICSs and statins) was associated with increased rates of new-onset diabetes. Further research is warranted to understand this association.

Abstract
BACKGROUND Among elderly patients, the management of type 2 diabetes mellitus (T2DM) is complicated by population heterogeneity and elderly-specific complexities. Few studies have been done to understand treatment intensification among elderly patients failing multiple oral antidiabetic drugs (OADs). OBJECTIVE To examine the association between time to treatment intensification of T2DM and elderly-specific patient complexities. METHODS In this observational, retrospective cohort study, elderly (aged ≥ 65 years) Medicare beneficiaries (n = 16,653) with inadequately controlled T2DM (hemoglobin A1c ≥ 8.0% despite 2 OADs) were included. Based on the consensus statement for diabetes care in elderly patients published by the American Diabetes Association and the American Geriatric Society, elderly-specific patient complexities were defined as the presence or absence of 5 geriatric syndromes: cognitive impairment; depression; falls and fall risk; polypharmacy; and urinary incontinence. RESULTS Overall, 48.7% of patients received intensified treatment during follow-up, with median time to intensification 18.5 months (95% CI = 17.7-19.3). Median time to treatment intensification was shorter for elderly patients with T2DM with polypharmacy (16.5 months) and falls and fall risk (12.7 months) versus those without polypharmacy (20.4 months) and no fall risk (18.6 months). Elderly patients with urinary incontinence had a longer median time to treatment intensification (18.6 months) versus those without urinary incontinence (14.6 months). The median time to treatment intensification did not significantly differ by the elderly-specific patient complexities that included cognitive impairment and depression. However, after adjusting for demographic, insurance, clinical characteristics, and health care utilization, we found that only polypharmacy was associated with time to treatment intensification (adjusted hazard ratio, 1.10; 95% CI = 1.04-1.15; P = 0.001). CONCLUSIONS Less than half of elderly patients with inadequately controlled T2DM received treatment intensification. Elderly-specific patient complexities were not associated with time to treatment intensification, emphasizing a positive effect of the integrated health care delivery model. Emerging health care delivery models that target integrated care may be crucial in providing appropriate treatment for elderly T2DM patients with complex conditions.
