Initial maintenance therapy adherence among older adults with asthma-COPD overlap.

OBJECTIVES: To examine the impact of initial maintenance therapy (IMT) type (inhaled corticosteroid [ICS] vs fixed-dose combination of ICS and long-acting ß agonist [ICS/LABA]) on trajectories of adherence among older adults (≥ 65 years) with coexisting asthma and chronic obstructive pulmonary disease (COPD), known as asthma-COPD overlap (ACO). STUDY DESIGN: We used a longitudinal, retrospective cohort design. METHODS: This study used a cohort of older adults with ACO using longitudinal data from a 10% sample of Optum's Deidentified Clinformatics Data Mart. We adopted group-based trajectory modeling to identify medication adherence trajectories over 12 months. Multinomial logistic regressions were used to evaluate the unadjusted and adjusted associations of IMT medication and adherence trajectory categories. All analyses accounted for treatment option selection bias with inverse probability treatment weighting. RESULTS: Of 1555 individuals, 73% of the sample used ICS/LABA for IMT. Four medication adherence trajectories were observed regardless of regimen: (1) persistent high adherence (12.0%), (2) progression to high adherence (20.8%), (3) progression to low adherence (10.5%), and (4) persistent low adherence (56.7%). Those who were initiated on ICS/LABA were less likely to have persistent low adherence (unadjusted odds ratio [OR], 0.44; 95% CI, 0.29-0.67) compared with those initiated on ICS monotherapy when "persistent high adherence" was used as the reference group. The relationship remained significant in adjusted regressions (adjusted OR, 0.38; 95% CI, 0.24-0.59). CONCLUSIONS: Real-world evidence suggests that using ICS/LABA for IMT may decrease the likelihood of persistent low adherence over time among older adults with ACO compared with ICS monotherapy.

Determining the Entrepreneurial and Intrapreneurial Intentions of Student Pharmacists in Iran.

Objective. To identify factors and entrepreneurial characteristics associated with entrepreneurial and intrapreneurial intentions among Doctor of Pharmacy (PharmD) students in Iran.Methods. First, the Entrepreneurial-Intrapreneurial Pharmacist Questionnaire (EIPQ), which was developed in the United States, was translated from English to Persian. The paper-based Persian-EIPQ questionnaire was then tested in a convenience sample of student pharmacists enrolled in pharmacy schools in Iran. The entrepreneurial characteristics questionnaire was evaluated using exploratory factor analysis with varimax rotation. Internal consistency was examined using Cronbach alpha. The association of demographics and educational variables and entrepreneurial characteristics with entrepreneurial and intrapreneurial intentions was determined using a multiple linear regression model.Results. A total of 504 surveys, 98.6% of the completed questionnaires received, were analyzed. A majority of the participants were female (75.8%) and from 18 to 25 years old (92.2%). Entrepreneurial intention had a positive and significant association with risk-taking propensity, leadership self-efficacy, autonomy, achievement motivation, and having an entrepreneur in the family. Intrapreneurial intention had a positive and significant association with risk-taking propensity, leadership self-efficacy, achievement motivation, people liking, attending a private school, and having an entrepreneur in the family.Conclusion. Based on the findings, student pharmacists with higher levels of risk-taking propensity, achievement motivation, leadership self-efficacy, autonomy, and people liking may be more likely to have greater levels of entrepreneurial and/or intrapreneurial intention.

Economic Burden of Asthma-Chronic Obstructive Pulmonary Disease Overlap among Older Adults in the United States.

The objective of this study is to estimate the excess economic burden of Asthma-COPD Overlap (ACO) among older adults in the United States. We used a cross-sectional study design with data from a nationally representative survey of Medicare beneficiaries (Medicare Current Beneficiary Survey) linked to Medicare fee-for-service claims. Older adults with ACO had higher average total healthcare expenditures ($45,532 vs. $12,743) and higher out-of-pocket spending burden (19% vs. 8.5%) compared to those with no-asthma no-COPD (NANC). Individuals with ACO also had almost two, and 1.5 times higher expenditures compared to individuals with asthma only and COPD only, respectively. Multivariable regression models indicated that the adjusted associations of ACO to economic burden remained positive and statistically significant. In comparison with NANC, nearly three-quarters of the excess total healthcare expenditures and 83% of the out-of-pocket spending burden of older adults with ACO were explained by differences in predisposing, enabling, need, personal healthcare practices, and external factors among the two groups. The higher number of unique medications and the increased incidence of fragmented care were the leading contributors to the excess economic burden among older adults with ACO comparing to NANC individuals. Interventions that reduce the number of medications and fragmented care have the potential to reduce the excess economic burden among older adults with ACO.

Association of Entrepreneurial Traits With Interest in Becoming a Pharmacist Provider Among Student Pharmacists.

BACKGROUND: With the emerging opportunities for pharmacists to gain provider status, the need for understanding interest to become a pharmacist provider has never been greater. OBJECTIVE: To determine which entrepreneurial traits (locus of control, innovativeness, autonomy, risk-taking propensity, proactiveness, achievement motivation, people liking, problem-solving, and leadership) are associated with interest in becoming a pharmacist provider. METHODS: A cross-sectional survey was conducted among second- and third-year student pharmacists. Exploratory factor analysis (principal components with varimax rotation) was used to determine any underlying dimensions. Significant differences in interest in becoming a pharmacist provider by demographic and other characteristics were determined using t tests and analysis of variance (ANOVA; P ≤ .05). Multiple linear regression was used to determine the factors associated with interest in becoming a pharmacist provider. RESULTS: A total of 137 completed questionnaires were received. Gender (P = .003) and preference of workplace (P < .001) were significantly associated with interest in becoming a pharmacist provider. All factor loadings were more than 0.50 and Cronbach alpha values were more than .68. In the multiple linear regression analysis model, proactiveness (P = .036) and achievement motivation (P = .018) were positive predictors of interest in becoming a pharmacist provider. Females (P = .006) and individuals who preferred to work in a hospital (P < .001) or in specialty care (P = .007) had a significantly greater interest in becoming a pharmacist provider. CONCLUSIONS: Proactiveness and achievement motivation can be predictors of interest in becoming a pharmacist provider.

Initial Validation of an Instrument for Measuring Entrepreneurial and Intrapreneurial Intentions in Student Pharmacists.

Objective. To develop a questionnaire for measuring entrepreneurial and intrapreneurial intentions among student pharmacists and to identify characteristics and personality traits that are associated with these intentions. Methods. A 105-item survey instrument was developed and administered to all Doctor of Pharmacy (PharmD) students (incoming to third year) at a large public university. It consisted of nine scales pertaining to entrepreneurism including previously validated and some newly developed scales adapted for use among student pharmacists. Data analysis consisted of factor analysis to determine scale constructs, reliability assessment, and systematic item-reduction analysis. Multiple linear regression and structural equation modeling was used to determine and confirm the association of personality traits and demographic characteristics with entrepreneurial and intrapreneurial intentions. Results. Of 289 students surveyed, 286 useable survey instruments were included in the analysis. Factor analysis was conducted for each scale, and items that did not load on their theorized factor or had cross-loadings above the permissible limits were removed, reducing the survey to 69 items. Findings demonstrated that gender, joint degree program, and autonomy were significant predictors of entrepreneurial intentions, and achievement motivation, leadership self-efficacy, and problem-solving were significant predictors of intrapreneurial intentions. Conclusion. A multi-dimensional questionnaire to measure entrepreneurial and intrapreneurial intentions of student pharmacists was developed and a few key predictors of such intentions were identified. When fully validated, the questionnaire may be used in pharmacy schools for several purposes, including in the PharmD admission process to gain additional insights into a student's potential to become a future innovative entrepreneurial or intrapreneurial practitioner.

Receipt of Guideline-Concordant Care Among Older Women With Stage I-III Breast Cancer: A Population-Based Study.

Background: This study examined receipt of guideline-concordant care (GCC) according to evidence-based treatment guidelines and quality measures and specific types of treatment among older women with breast cancer. Patients and Methods: A total of 142,433 patients aged ≥66 years diagnosed with stage I-III breast cancer between 2007 and 2011 were identified in the SEER-Medicare linked database. Algorithms considering cancer characteristics and the appropriate course of care as per guidelines versus actual care received determined receipt of GCC. Multivariable logistic regression estimated the likelihood of GCC and specific types of treatment for women aged ≥75 versus 66 to 74 years. Results: Overall, 39.7% of patients received GCC. Patients diagnosed at stage II or III, with certain preexisting conditions, and of nonwhite race were less likely to receive GCC. Patients with hormone-negative tumors, higher grade tumors, and greater access to oncology care resources were more likely to receive GCC. Patients aged ≥75 years were approximately 40% less likely to receive GCC or adjuvant endocrine therapy, 78% less likely to have any surgery, 61% less likely to have chemotherapy, and about half as likely to have radiation therapy than those aged 66 to 74 years. Conclusions: Fewer than half of older women with breast cancer received GCC, with the lowest rates observed among the oldest age groups, racial/ethnic minorities, and women with later-stage cancers. However, patients with more aggressive tumor characteristics and greater access to oncology resources were more likely to receive GCC. Considering that older women have the highest incidence of breast cancer and that many are diagnosed at stages requiring more aggressive treatment, efforts to increase rates of earlier stage diagnosis and the development of less toxic treatments could help improve GCC and survival while preserving quality of life.

Association of the severity of diabetes-related complications with stage of breast cancer at diagnosis among elderly women with pre-existing diabetes.

PURPOSE: This study assessed the association between the severity of diabetes complications using diabetes complications severity index (DCSI) and stage of breast cancer (BC) at diagnosis among elderly women with pre-existing diabetes and incident BC. METHODS: Using Surveillance, Epidemiology and End Results-Medicare data, we identified women with incident BC during 2004-2011 and pre-existing diabetes (N = 7729). Chi-square tests were used to test for group differences in stage of BC at diagnosis. Multinomial logistic regression was used to examine the associations between the severity of diabetes complications and stage of BC at diagnosis. RESULTS: Overall, women with a DCSI = 2 and a DCSI ≥ 3 were more likely to be diagnosed at advanced stages as compared to those with no diabetes complications. In full adjusted association (after adding BC screening to the analysis model), the severity of diabetes complications was no longer an independent predictor of advanced stages at diagnosis. However, women with a DCSI = 2 were 26% more likely to be diagnosed at stage I (versus stage 0) of BC at diagnosis as compared to those without diabetes complications (OR 1.26, 95% CI 1.03-1.53). CONCLUSION: The increased likelihood of having advanced-stage BC at diagnosis associated with severity of diabetes-related complications appears to be mediated by lower rates of breast cancer screening among elderly women with pre-existing diabetes complications. Therefore, reducing disparity in receiving breast cancer screening among elderly women with diabetes may reduce the risk of advanced-stage breast cancer diagnosis.

Healthcare Utilization and Costs During the Initial Phase of Care Among Elderly Women With Breast Cancer.

Background: Understanding the patterns of healthcare utilization and costs during the initial phase of care (12 months after breast cancer [BC] diagnosis) in older women (aged ≥65 years) is crucial in the allocation of Medicare resources. The objective of this study was to determine healthcare utilization and costs during the initial phase of care in older, female, Medicare fee-for-service beneficiaries diagnosed with BC, and to determine the factors associated with higher costs. Methods: A retrospective observational study using the SEER-Medicare linked database was conducted in 69,307 women aged ≥66 years diagnosed with primary incident BC in 2003-2009 to determine healthcare utilization, average costs, and costs for specific services during the initial phase of care. Generalized linear model regression was conducted to identify the factors associated with higher costs in a multivariate framework. Results: A total of 96% of women were treated with surgery during the initial phase of BC care, whereas 21% and 54% underwent chemotherapy and radiotherapy, respectively. Costs during the initial phase of care totalled $28,075 in 2012 USD, comprising $13,344 for physician services and $7,456 for outpatient services. Factors associated with higher costs during the initial phase of care were younger age (66-69 years), African American race, higher household income, advanced stages of BC, initial BC treatment, higher number of primary care physician visits, and presence of comorbidities and/or a mental condition. Conclusions: The economic burden of BC is substantial during the initial phase of care. Physician and outpatient services accounted for the highest proportion of costs. Predisposing factors, need-related factors, healthcare use, and external environmental healthcare factors significantly predicted costs during the initial phase of care.

Differences in Medicare Expenditures Between Appalachian and Nationally Representative Cohorts of Elderly Women With Breast Cancer: An Application of Decomposition Technique.

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.

Treatment and Survival of Medicare Beneficiaries with Colorectal Cancer: A Comparative Analysis Between a Rural State Cancer Registry and National Data.

The aim was to examine and compare with "national" estimates, receipt of colorectal cancer (CRC) treatment in the initial phase of care and survival following a CRC diagnosis in rural Medicare beneficiaries. A retrospective study was conducted on fee-for-service Medicare beneficiaries diagnosed with CRC in 2003-2006, identified from West Virginia Cancer Registry (WVCR)-Medicare linked database (N = 2119). A comparative cohort was identified from Surveillance, Epidemiology, and End Results (SEER)-Medicare (N = 38,168). CRC treatment received was ascertained from beneficiaries' Medicare claims in the 12 months post CRC diagnosis or until death, whichever happened first. Receipt of minimally appropriate CRC treatment (MACT) was defined using recommended CRC treatment guidelines. All-cause and CRC-specific mortality in the 36-month period post CRC diagnosis were examined. Differences in usage of CRC surgery, chemotherapy, and radiation were observed between the 2 populations, with those from WVCR-Medicare being less likely to receive any type of CRC surgery (adjusted odds ratio [AOR] = 0.82; 95% confidence interval [CI] = [0.73-0.93]). Overall, those from WVCR-Medicare had a lower likelihood of receiving MACT, (AOR = 0.85; 95% CI = [0.76-0.96]) compared to their national counterparts. Higher hazard of CRC mortality was observed in the WVCR-Medicare cohort (adjusted hazard ratio = 1.26; 95% CI = [1.20-1.32]) compared to the SEER-Medicare cohort. Although more beneficiaries from WVCR-Medicare were diagnosed in early-stage CRC compared to their SEER-Medicare counterparts, they had a lower likelihood of receiving MACT and a higher hazard of CRC mortality. This study highlights the need for an increased focus on improving access to care at every phase of the CRC care continuum, especially for those from rural settings.

Comparison of the Initial Loco-Regional Treatment Received for Early-Stage Breast Cancer between Elderly Women in Appalachia and a United States - Based Population: Good and Bad News.

BACKGROUND: Breast conserving surgery (BCS) followed by radiation therapy (RT) (BCS+RT) is as effective for long-term survival of invasive early-stage breast cancer (ESBC) as mastectomy, and is the local treatment option selected by the majority of women with ESBC. Women of older age and vulnerable socio-demographic characteristics are at greater risk for receiving substandard (BCS only) and non-preferred treatments (mastectomy), such as populations of women from the Appalachian region of United States. METHODS: Using a retrospective cohort study design, we identified 26,106 patients from the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked dataset and 811 patients from the West Virginia Cancer Registry (WVCR)-Medicare dataset age ≥ 66 diagnosed from 2003 to 2006 with stage I-II breast cancer. Multivariable logistic regression models estimated type of initial treatment received between WVCR-Medicare and SEER-Medicare patients, and the association with type of treatment. RESULTS: Overall, women in WV were 0.82 (95% CI 0.68-0.99) and 0.70 (95% CI 0.58-0.84) times less likely to have mastectomy or BCS only vs. BCS+RT, than those in SEER regions. Women in WV of increasing age, greater comorbidity, stage II disease, and non-white race were more likely to have mastectomy or BCS only vs. BCS+RT, whereas, those residing in areas of higher income, higher education, and metro status were less likely, than similarly characterized women from SEER regions. CONCLUSIONS: Findings from this study suggest that the magnitude of disparities in breast cancer treatment between groups of women with more and less resources are even greater in the Appalachian region, than they are among US populations. Improving access to oncology treatment services, as well as, the implementation of patient navigation programs are needed to improve patterns of initial treatment for ESBC among at-risk populations.

Caregiver Burdens and Preventive Dental Care for Children with Autism Spectrum Disorder, Developmental Disability and/or Mental Health Conditions: National Survey of CSHCN, 2009-2010.

Objective The purpose of this study is to examine the burdens of caregivers on perception of the need and receipt of preventive dental care for a subset of children with special health care needs-children with Autism Spectrum disorder, developmental disability and/or mental health conditions (CASD/DD/MHC). Methods The authors used the 2009-2010 National Survey of CSHCN. The survey included questions addressing preventive dental care and caregivers' financial, employment, and time-related burdens. The associations of these burdens on perceptions and receipt of preventive dental care use were analyzed with bivariate Chi square analyses and multinomial logistic regressions for CASD/DD/MHC (N = 16,323). Results Overall, 16.3 % of CASD/DD/MHC had an unmet preventive dental care need. There were 40.0 % of caregivers who reported financial burden, 20.3 % who reported employment burden, and 10.8 % who reported time burden. A higher percentage of caregivers with financial burden, employment burden, and time-related burden reported that their CASD/DD/MHC did not receive needed preventive dental care (14.1, 16.5, 17.7 % respectively) compared to caregivers without financial, employment, or time burdens (9.0, 9.6 %, 11.0 % respectively). Caregivers with financial burden (adjusted multinomial odds ratio, 1.38 [95 % CI 1.02, 1.86] and employment burden (adjusted multinomial odds ratio, 1.45 [95 % CI 1.02, 2.06] were more likely to report that their child did not receive preventive dental care despite perceived need compared to caregivers without financial or employment burdens. Conclusions for practice Unmet needs for preventive dental care were associated with employment and financial burdens of the caregivers of CASD/DD/MHC.

Disparities in Lung Cancer Care and Outcomes among Elderly in a Medically Underserved State Population-A Cancer Registry-Linked Database Study.

Despite availability of guidelines for lung cancer care, variations in lung cancer care among the elderly exist across the nation and are a cause for concern in rural and medically underserved areas. Therefore, the purpose of this study was to evaluate the patterns of lung cancer care and associated health outcomes among elderly residing in a rural and medically underserved area. The authors identified 1924 elderly lung cancer patients from the West Virginia Cancer Registry-Medicare linked database (2002-2007) and categorized them by receipt of guideline-concordant (appropriate and timely) care using guidelines from the American College of Chest Physicians, British Thoracic Society, and the RAND Corporation. Hierarchical generalized logistic models were constructed to identify variables associated with receipt of guideline-concordant care. Kaplan-Meier analysis and log-rank test were used to compare 3-year survival outcomes. Multivariate Cox proportional hazards models were constructed to estimate lung cancer mortality risk associated with nonreceipt of guideline-concordant care. Although guideline-concordant appropriate care was received by fewer than half of all patients (46.5%), of those receiving care, 78.7% received it in a timely manner. Delays in diagnosis and treatment varied significantly. Survival outcomes significantly improved with appropriate care (799 vs. 366 days; P≤0.05), but did not improve with timely care. This study highlights the critical need to address disparities in receipt of guideline-concordant lung cancer care among the elderly residing in rural and medically underserved areas. Although lung cancer diagnostic and management services are covered under the Medicare program, underutilization of these services is a concern. (Population Health Management 2016;19:109-119).

Tobacco-use Cessation Counseling Service Usage.

Objectives: Tobacco-use is common among elderly lung cancer patients and continued tobacco-use can impact prognosis. This study evaluates patterns of receipt of Tobacco-use Cessation Counseling (TCC) services among these patients. Methods: Using West Virginia Cancer Registry-Medicare linked database (2004-2007), we identified elderly patients with lung cancer (n = 922) and categorized them by receipt of TCC services. Hierarchical generalized logistic model was constructed and survival outcomes were analyzed by Kaplan-Meier analysis, Log-Rank test, and Cox proportional hazards modeling. Results: Majority of patients (76.7%) received TCC services. Unadjusted analysis showed favorable survival outcomes in patients who received TCC services. However, adjusted lung cancer mortality risk was no different between the groups (HR (95% CI) = 1.78 (0.87-3.64)). Conclusion: This study highlights the critical need to address disparities in receipt of TCC services among elderly. Although lung cancer preventive services are covered under the Medicare program, underutilization of these services is a concern.

A Discrete Choice Experiment to Elicit Patient Willingness to Pay for Attributes of Treatment-Induced Symptom Relief in Comorbid. Insomnia.

PURPOSE: Insomnia is a burdensome, commonly comorbid condition. How patients value various aspects of the safety and efficacy of available drugs has not been studied. The aim of the present study was to quantify patient-rated utility by studying willingness to pay (WTP) for attributes of symptom relief via a discrete choice experiment (DCE). METHODOLOGY: Adult primary care patients (West Virginia University Hospital) with comorbid insomnia were enrolled. The attributes and levels examined were sleep onset latency (SOL; 10, 20,30 minutes), awakenings (1, 2, 3), wake time after sleep onset (WASO; 15,45, 60 minutes), total sleep time (TST; 6, 7, 8 hours), hangover (none, mild, moderate), FDA-approved duration of use (short term, not restricted to short term, no restrictions), and out-of-pocket cost per month ($20, $35, $50). Willingness to pay (WTP) data were analyzed using a random effects binary logistic regression model. RESULTS: A total of 82 patients completed the DCE (74 analyzed). SOL, WASO, TST, and cost were all found to predict treatment choice. Higher values of SOL, WASO, and cost resulted in decreased preference for a particular treatment, while higher TST predicted increased preference. Modeling revealed an estimated marginal WTP of $66.69 for an example product that improved SOL by 10 minutes, reduced WASO by 15 minutes, and improved TST by 1 hour. CONCLUSION: Patient WTP for symptomatic relief in insomnia can help clinicians fine-tune interventions based on patient preferences, provide evidence for drug formulary and reimbursement decisions, and potentially guide the development of novel drugs.

Guideline-concordant timely lung cancer care and prognosis among elderly patients in the United States: A population-based study.

OBJECTIVES: Elderly carry a disproportionate burden of lung cancer in the US. Therefore, its important to ensure that these patients receive quality cancer care. Timeliness of care is an important dimension of cancer care quality but its impact on prognosis remains to be explored. This study evaluates the variations in guideline-concordant timely lung cancer care and prognosis among elderly in the US. MATERIALS AND METHODS: Using the Surveillance, Epidemiology, and End Results (SEER)-Medicare database (2002-2007), we identified elderly patients with lung cancer (n=48,850) and determined time to diagnosis and treatment. We categorized patients by receipt of timely care using guidelines from the British Thoracic Society and the RAND Corporation. Hierarchical generalized logistic model was constructed to identify variables associated with receipt of timely care. Kaplan-Meier analysis and Log Rank test was used for estimation and comparison of the three-year survival. Multivariable Cox proportional hazards model was constructed to estimate lung cancer mortality risk associated with receipt of delayed care. RESULTS: Time to diagnosis and treatment varied significantly among the elderly. However, majority of them (77.5%) received guideline-concordant timely lung cancer care. The likelihood of receiving timely care significantly decreased with NSCLC disease, early stage diagnosis, increasing age, non-white race, higher comorbidity score, and lower income. Paradoxically, survival outcomes were significantly worse among patients receiving timely care. Adjusted lung cancer mortality risk was also significantly lower among patients receiving delayed care, relative to those receiving timely care (Hazard ratio (HR)=0.68, 95% Confidence interval (CI)=(0.66-0.71); p ≤ 0.05). CONCLUSION: This study highlights the critical need to address disparities in receipt of guideline-concordant timely lung cancer care among elderly. Although timely care was not associated with better prognosis in this study, any delays in diagnosis and treatment should be avoided, as it may increase the risk of disease progression and psychological stress in patients. Furthermore, given that lung cancer diagnostic and management services are covered under the Medicare program, observed delays in care among Medicare beneficiaries is also a cause for concern.

Guideline-concordant lung cancer care and associated health outcomes among elderly patients in the United States.

OBJECTIVES: In the United States (US), the elderly carry a disproportionate burden of lung cancer. Although evidence-based guidelines for lung cancer care have been published, lack of high quality care still remains a concern among the elderly. This study comprehensively evaluates the variations in guideline-concordant lung cancer care among elderly in the US. MATERIALS AND METHODS: Using the Surveillance, Epidemiology, and End Results (SEER)-Medicare database (2002-2007), we identified elderly patients (aged ≥65 years) with lung cancer (n = 42,323) and categorized them by receipt of guideline-concordant care, using evidence-based guidelines from the American College of Chest Physicians. A hierarchical generalized logistic model was constructed to identify variables associated with receipt of guideline-concordant care. Kaplan-Meier analysis and Log Rank test were used for estimation and comparison of the three-year survival. Multivariate Cox proportional hazards model was constructed to estimate lung cancer mortality risk associated with receipt of guideline-discordant care. RESULTS: Only less than half of all patients (44.7%) received guideline-concordant care in the study population. The likelihood of receiving guideline-concordant care significantly decreased with increasing age, non-white race, higher comorbidity score, and lower income. Three-year median survival time significantly increased (exceeded 487 days) in patients receiving guideline-concordant care. Adjusted lung cancer mortality risk significantly increased by 91% (HR = 1.91, 95% CI: 1.82-2.00) among patients receiving guideline-discordant care. CONCLUSION: This study highlights the critical need to address disparities in receipt of guideline-concordant lung cancer care among elderly. Although lung cancer diagnostic and management services are covered under the Medicare program, underutilization of these services is a concern.

An explanatory model for state Medicaid per capita prescription drug expenditures.

Rising prescription drug expenditure is a growing concern for publicly funded drug benefit programs like Medicaid. To be able to contain drug expenditures in Medicaid, it is important that cause(s) for such increases are identified. This study attempts to establish an explanatory model for Medicaid prescription drugs expenditure based on the impacts of key influencers/predictors identified using a comprehensive framework of drug utilization. A modified Andersen's behavior model of health services utilization is employed to identify potential determinants of pharmaceutical expenditures in state Medicaid programs. Level of federal matching funds, access to primary care, severity of diseases, unemployment, and education levels were found to be key influencers of Medicaid prescription drug expenditure. Increases in all, except education levels, were found to result in increases in drug expenditures. Findings from this study could better inform intervention policies and cost-containment strategies for state Medicaid drug benefit programs.

Patterns of cervical cancer screening, diagnosis, and follow-up treatment in a state Medicaid fee-for-service population.

Despite being a screening-amenable cancer, cervical cancer is the third most common genital cancer among white women and the most common among African American women. The study objective was to use administrative claims data for CC disease surveillance among recipients enrolled in a state Medicaid fee-for-service (FFS) program. West Virginia (WV) Medicaid FFS administrative claims data for female recipients aged 21-64 years from 2003 to 2008 were used for this study. All medical and prescription claims were aggregated to reflect each recipient's medical care and prescription drug utilization. The yearly prevalence of Pap smear testing declined from 23.9% in 2003 to 15.8% in 2008 in the Medicaid FFS population. During the 6-year study period, persistence with Pap smear testing was low; 41.8% of recipients received no Pap smear testing. Only 73.1% of recipients received Pap smear testing during the year prior to their CC or precancerous cervical lesions (PCL) diagnosis. The likelihood of a CC diagnosis increased with a decrease in Pap smear testing persistence. Only 10.1% of recipients received appropriate follow-up care following a diagnosis of high-grade PCL; only 31.5% of the recipients received appropriate follow-up care for low-grade PCL diagnosis. Although CC preventive services such as screening and PCL follow-up care are covered under Medicaid programs, underutilization of these services by recipients in the Medicaid FFS population is a concern. Results of this study emphasize the need to address disparities in screening and appropriate PCL follow-up care among recipients in the Medicaid FFS population.
