    ABSTRACT: This study determined the impact of preexisting mental illnesses on guideline-consistent breast cancer treatment and breast cancer-related health care utilization. This was a retrospective, longitudinal, cohort study conducted using data from the 2006-2008 Medicaid Analytic Extract files. The target population for the study consisted of female Medicaid enrollees who were aged 18-64 years and were newly diagnosed with breast cancer in 2007. Guideline-consistent breast cancer treatment was defined according to established guidelines. Breast cancer-related health care use was reported in the form of inpatient, outpatient, and emergency room visits. Statistical analyses consisted of multivariable hierarchical regression models. A total of 2142 newly diagnosed cases of breast cancer were identified. Approximately 38% of these had a preexisting mental illness. Individuals with any preexisting mental illness were less likely to receive guideline-consistent breast cancer treatment compared to those without any preexisting mental illness (adjusted odds ratio: 0.793, 95% confidence interval [CI]: 0.646-0.973). A negative association was observed between preexisting mental illness and breast cancer-related outpatient (adjusted incident rate ratio (AIRR): 0.917, 95% CI: 0.892-0.942) and emergency room utilization (AIRR: 0.842, 95% CI: 0.709-0.999). The association between preexisting mental illnesses and breast cancer-related inpatient utilization was statistically insignificant (AIRR: 0.993, 95% CI: 0.851-1.159). The findings of this study indicate that breast cancer patients with preexisting mental illnesses experience disparities in terms of receipt of guideline-consistent breast cancer treatment and health care utilization. The results of this study highlight the need for more focused care for patients with preexisting mental illness. (Population Health Management 2015;xx:xxx-xxx).

    ABSTRACT: Erythropoiesis-stimulating agents (ESAs), found to be effective in reducing anemia in chemotherapy-treated cancer patients, also are associated with an increased risk of cardiovascular events, including stroke. In an attempt to mitigate the risk, the Food and Drug Administration implemented a Risk Evaluation Mitigation Strategy (REMS) in February 2010. The purpose of this study is to evaluate change over time in the incidence of stroke among these patients before and after implementation of REMS. A retrospective data analysis using the Medicare 5% Sample Dataset, 2008-2011, was performed. Patients had to be 65 years of age or older at the start of at least 1 year of continuous enrollment and to have lung and/or breast cancers along with chemotherapy-induced anemia (CIA) in both pre-REMS and post-REMS periods (1Q2008 through 4Q2009 and 1Q2010 through 4Q2011, respectively). Logistic regression was used to evaluate differences in proportions of patients who received ESAs and experienced a stroke pre and post REMS. The pre-REMS cohort included 1252 eligible patients prescribed ESAs; the post-REMS cohort included 949 patients. No statistically significant change in stroke incidence was observed post REMS among patients with CIA who received ESAs. There was a 29.5% decrease in ESA use in patients with lung cancer and a 27.8% decrease in patients with breast cancer. Both were statistically significant. Results adjusted for baseline characteristics and comorbid conditions were similar. There was a statistically significant decrease in ESA use in patients with breast and/or lung cancers post REMS; no statistically significant reduction in the incidence of stroke was observed regardless of cancer type.

    ABSTRACT: Childhood asthma is a prevalent and costly chronic condition. Optimal management enables secondary and tertiary prevention. The goal was to identify population health considerations for pediatric asthma in California to inform the development of quality improvement interventions. California Health Interview Survey 2011-2012 is a random-digit dial telephone survey conducted in 5 languages. It includes 44,000 households from all 58 counties in California. This study assessed factors related to symptom control and health care use in children ages 2-11 years with asthma. An estimated 492,385 (9.6%) of children in California currently have asthma. Urban and rural residents face comparable asthma disease burdens. School-age male children as well as Asian and African American children are disproportionately affected. Asthma causes significant morbidity, with poorer health status, high utilization of emergency care, and the need for daily medication use. Only 38% of children with asthma have a recent asthma management plan. Half of all children with asthma did not receive influenza immunization in the past year, although this reflects the overall low rate of influenza vaccination. Parents of children with asthma frequently utilize the Internet for health information and communication with their child's health care provider. Children with asthma in California face several population-level challenges, including poor health status, low influenza vaccination rates, high use of emergency care, and suboptimal use of health literacy tools. Focusing on improved care coordination and preventive care for high-risk groups is especially urgent given the expansion of public health insurance and impending shortages in the primary care workforce.

    ABSTRACT: The objective was to determine whether automated telephone self-management support (ATSM) for low-income, linguistically diverse health plan members with diabetes affects health care utilization or cost. A government-sponsored managed care plan for low-income patients implemented a demonstration project between 2009 and 2011 that involved a 6-month ATSM intervention for 362 English-, Spanish-, or Cantonese-speaking members with diabetes from 4 publicly funded clinics. Participants were randomized to immediate intervention or a wait-list. Medical and pharmacy claims used in this analysis were obtained from the managed care plan. Medical claims included hospitalizations, ambulance use, emergency department visits, and outpatient visits. In the 6-month period following enrollment, intervention participants generated half as many emergency department visits and hospitalizations (rate ratio 0.52, 95% CI 0.26, 1.04) compared to wait-listed participants, but these differences did not reach statistical significance (P=0.06). With adjustment for prior year cost, intervention participants also had a nonsignificant reduction of $26.78 in total health care costs compared to wait-listed individuals (P=0.93). The observed trends suggest that ATSM could yield potential health service benefits for health plans that provide coverage for chronic disease patients in safety net settings. ATSM should be further scaled up to determine whether it is associated with a greater reduction in health care utilization and costs. (Population Health Management 2015;xx:xxx-xxx).

    ABSTRACT: Increasing scrutiny of hospital readmission rates has spurred a wide variety of quality improvement initiatives. The Preventing Avoidable Readmissions Together (PART) initiative is a statewide quality improvement learning collaborative organized by stakeholder organizations in South Carolina. This descriptive report focused on initial interventions with hospitals. Eligible participants included all acute care hospitals plus home health organizations, nursing facilities, hospices, and other health care organizations. Measures were degree of statewide participation, curricular engagement, adoption of evidence-based improvement strategies, and readmission rate changes. Fifty-nine of 64 (92%) acute care hospitals and 9 of 10 (90%) hospital systems participated in collaborative events. Curricular engagement included: webinars and coaching calls (49/59, 83%), statewide in-person meetings (35/59, 59%), regional in-person meetings (44/59, 75%), and individualized consultations (46/59, 78%). Among 34 (58%) participating hospitals completing a survey at the completion of Year 1, respondents indicated complete implementation of multidisciplinary rounding (58%), post-discharge telephone calls (58%), and teach-back (32%), and implementation in process of high-quality transition records (52%), improved discharge summaries (45%), and timely follow-up appointments (39%). A higher proportion of hospitals had significant decreases (≥10% relative change) in all-cause readmission rates for acute myocardial infarction (55.6% vs. 30.4%, P=0.01), heart failure (54.2% vs. 31.7%, P=0.09), and chronic obstructive pulmonary disease (41.7% vs. 33.3%, P=0.83) between 2011-2013 compared to earlier (2009-2011) trends. Focus on reducing readmissions is driving numerous, sometimes competing, quality improvement initiatives. PART successfully engaged the majority of acute care facilities in one state to harmonize and accelerate adoption of evidence-based care transitions strategies.

    ABSTRACT: This paper examined individual characteristics associated with being a high-cost case in multiple years for Medicaid-covered health care services. In addition, the accuracy of models that predict future persistent high-cost cases was examined. Florida Medicaid claims from 2005 to 2010 were used to examine characteristics, diagnoses, and services associated with individual costs being in the top 1% of recipients. Regression models were estimated with diagnoses and service use in a base year used to predict future high-cost cases. Several different perspectives were used that focus on predicting current year high-cost cases based on prior persistence, predicting future persistence of high costs, and a combination of using past persistence to predict future persistence. Average annual costs for persistent high-cost cases were more than $140,000. Overall, models were predictive of future high-cost cases. The receipt of intermediate case facility (mental retardation) services was the strongest predictor of future high-cost cases. Inpatient, outpatient, pharmacy, and nursing home services, along with diagnoses, all provided important information for predicting high-cost cases. Diagnosis-based models in conjunction with prior costs can predict future high-cost cases with a high degree of accuracy. However, given that many high-cost cases reside in intermediate care facilities, it is not clear that such individuals would benefit from intensive case management. Service use patterns in prior years, diagnoses, and prior costs should all be used to identify individuals who may benefit from intensive case management.

    ABSTRACT: This study is an analysis of a workplace diabetes management program offered to employees of a Fortune 100 financial services corporation located in the United States. The 12-month worksite-based educational program was for employees who were at risk for diabetes, had prediabetes, or were diagnosed with diabetes. This employed population, with health benefits, generally had acceptable control of their diabetes at the start of the program. They statistically improved most self-efficacy measures, but improvement in biometric tests at 6 and 12 months were not significantly different from baseline. Mean hemoglobin A1c at baseline, 6 months, and 12 months was 7.2%, 7.2%, and 7.3%, respectively. At 12 months, about 40% of preprogram survey participants completed all screenings and the post-program questionnaire. Disease management programs at the workplace can be an important component in helping employees enhance their knowledge of diabetes and maintain and improve their health.

    ABSTRACT: This study assessed the hypothesis that the clinic site of service socioeconomic status (SES) represents an unmeasured confounder for clinical outcome comparisons between dialysis clinics and provider types, using data from the federal pay-for-performance program for end-stage renal disease. A total of 6506 dialysis facilities were categorized by clinic SES status (rurality and poverty status). Clinics were then grouped by provider type (chain size and tax status). Lastly, performance penalties were determined by each of these classifications. Findings were that 7.4% of dialysis clinics could be classified as being in rural locations, and 20.6% could be classified as being in high-poverty locations. Large dialysis organizations served more rural (65%) and high-poverty areas (metropolitan, 69%; micropolitan, 75%; rural, 75%) compared to other providers (medium, small, hospital/university). For-profit providers accounted for a majority of dialysis clinics in rural areas (78%) and high poverty areas (metropolitan, 84%; micropolitan, 85%; rural, 90%). This study found that dialysis clinic performance penalties did vary by SES, with poorer outcomes observed for clinic locations with lower SES. This finding, along with the nonrandom distribution of provider types by SES status, suggests that clinic and provider location SES may need to be considered when comparing providers.

    ABSTRACT: The Affordable Care Act has extended coverage for uninsured and underinsured Americans, but it could exacerbate existing problems of access to primary care. Shared medical appointments (SMAs) are one way to improve access and increase practice productivity, but few studies have examined the patient's perspective on participation in SMAs. To understand patient experiences, 5 focus group sessions were conducted with a total of 30 people in the San Francisco Bay Area. The sessions revealed that most participants felt that they received numerous tangible and intangible benefits from SMAs, particularly enhanced engagement with other patients and physicians, learning, and motivation for health behavior change. Most importantly, participants noted changes in the power dynamic during SMA visits as they increasingly saw themselves empowered to impart information to the physician. Although SMAs improve access, engagement with physicians and other patients, and knowledge of patients' health, they also help to ease the workload for physicians.

    ABSTRACT: Repetition by clinicians of the same tests for a given patient is common. However, not all repeat tests are necessary for optimal care and can result in unnecessary hardship. Limited evidence suggests that an electronic health record may reduce redundant laboratory testing and imaging by making previous results accessible to physicians. The purpose of this study is to establish a baseline by characterizing repeat testing in a pediatric population and to identify significant risk factors associated with repeated tests, including the impact of using multiple health systems. A population-based retrospective cross-sectional design was used to examine initial and repeat test instances, defined as a second test following an initial test of the same type for the same patient. The study population consisted of 8760 children with 1-25 test claims over a 1-year period. The study setting included all health care service organizations in Minnesota that generated these claims. In all, 17.2% of tests met the definition of repeat test instances, with several risk factors associated with per patient repeat test levels. The incidence of repeat test instances per patient was significantly higher when patients received care from more than 1 health system (adjusted incidence rate ratio 1.4; 95% confidence interval: 1.3-1.5). Repeat test levels are significant in pediatric populations and potentially actionable. Interoperable health information technology may reduce the incidence of repeat test instances in pediatric populations by making prior test results readily accessible.

    ABSTRACT: The purpose of this research was to retrospectively examine whether demographic differences exist between those who participated in an employee wellness program and those who did not, and to identify the selection of employees' choice in weight management activities. A nonequivalent, 2-group retrospective design was used. This study involved employees at a large, not-for-profit integrated health system. Of the total organization employee pool (29,194), 19,771 (68%) employees volunteered to be weighed (mean body mass index [BMI]=28.9) as part of an employee wellness program. Weight management activities available included: (1) Self-directed 5% total body weight loss; (2) Healthy Solutions at home; (3) Weight Watchers group meetings; (4) Weight Watchers online; and (5) Employee Assistance Program (EAP)-directed healthy weight coaching. Measures were participation rate and available weight management activity participation rate among obese employees across demographic variables, including sex, age, race, job type, and job location. The analysis included chi-square tests for all categorical variables; odds ratios were calculated to examine factors predictive of participation. Of the total 19,771 employees weighed, 6375 (32%) employees were obese (defined as BMI ≥30); of those, 3094 (49%) participated in available weight management activities. Participation was higher among females, whites, those ages >50 years, and non-nursing staff. In conclusion, participation rate varied significantly based on demographic variables. Self-directed 5% weight loss was the most popular weight management activity selected. (Population Health Management 2015;xx:xxx-xxx).

    ABSTRACT: Little is known about how to integrate primary care with mental/behavioral services outside of clinical trials. The authors implemented a collaborative care model (CCM) for depression in a safety net patient-centered medical home. The model focused on universal screening for symptoms, risk stratification based on symptom severity, care management for intensive follow-up, and psychiatry consultation. CCM increased rates of primary care physician encounters, timely follow-up for monitoring symptoms of depression, and documentation of treatment response. Contextual factors that facilitated or hindered practice redesign included clinic leadership, quality improvement culture, staffing, technology infrastructure, and external incentives/disincentives for organizational change.

    ABSTRACT: 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 2015;xx:xxx-xxx).

    ABSTRACT: Physical activity provides numerous health benefits, including reducing risk factors that contribute to the leading causes of morbidity and mortality. Many employers offer incentives to employees to motivate engagement in wellness program activities. Two incentive designs to reward employees for achieving step goals were evaluated. This study used a retrospective design and the study population consisted of benefit-eligible employees at American Specialty Health ages 18 to 65 years who completed a health assessment and biometric screening during 2011 (N=396) or 2012 (N=500). A total of 320 employees participated in both years. During 2011, the incentive goal was 500,000 steps per quarter. By comparison, a 3-tier step goal plan was implemented in 2012 (ie, 400,000; 650,000; or 900,000 steps/quarter). The prevalence of participants in the step program was 64.7% in 2011 and 72.8% in 2012. The percentage of employees who reached at least 1 quarterly incentive increased from 36.3% in 2011 to 51.4% in 2012. Average steps/day was higher in 2012 (mean [M]=3573, standard deviation [SD]=3010) compared to the same employees in 2011 (M=2817, SD=2654) (P<.001). The findings suggest that a tiered incentive design may be an effective population approach to engage employees in physical activity. A multitier incentive design offers participants choices for goal setting and may help shape behavior toward what may be perceived as a difficult goal to achieve.

    ABSTRACT: This analysis examined the efficacy of an automated postdischarge phone assessment for reducing hospital readmissions. All patients discharged between April 1, 2013, and January 31, 2014, from a single Level 1 trauma hospital of a large regional health system center utilizing an automated postdischarge phone assessment service were contacted via automated call between 24 and 72 hours post discharge. Patients answered 5 questions assessing perceived well-being, understanding of discharge instructions and medication regimen, satisfaction, and scheduled follow-up appointments. Responses could automatically prompt health personnel to speak directly with the patient. Data analysis examined rates of hospital readmission-any admission occurring within 30 days of a previous admission-for 3 broad categories of respondents: Answering Machine, Live Answer, and Unsuccessful. There were 6867 discharges included in the analysis. Of the Live Answer patients, 3035 answered all assessment questions; 153 (5.0%) of these had a subsequent readmission. Of the 738 Unsuccessful patients, 62 (8.4%) had a subsequent readmission. Unsuccessful patients were almost 2 times more likely to have a readmission than those who answered all 5 assessment questions. Of the latter group, readmission rates were highest for those who perceived a worsening of their condition (7.4%), and lowest for those reporting no follow-up appointment scheduled (3.8%).

    ABSTRACT: Self-management skills are helpful in making appropriate health-related decisions; however, improvements in self-management skills do not always translate into changes in health services utilization. Therefore, to assess associations between self-management skills and health services use, a randomly selected sample of 984 residents was drawn from South East Queensland, Australia. This cross-sectional study collected self-reported data on respondents' use of health services, health-related behaviors, demographics, and 3 self-management skills: self-monitoring, health services navigation, and social mobilization. The results indicate that the ability to navigate the health system was associated with greater use of health services while the ability to mobilize one's social supports was associated with reduced use of allied health services. Being able to navigate the health system appeared to be driven by necessity, in that those with higher navigation skills were unemployed, financially stressed, or had a chronic condition. This pattern of results confirms the socioeconomic gradient that exists in health. (Population Health Management 2015;xx:xxx-xxx).
