Direct Oral Anticoagulants and Warfarin for Atrial Fibrillation Treatment: Rural and Urban Trends in Medicare Beneficiaries.

BACKGROUND: Data are needed on the use of oral anticoagulation in patients with atrial fibrillation (AF) in rural versus urban areas, including the initiation of direct oral anticoagulants (DOACs). OBJECTIVE: We used Medicare data to examine rural/urban differences in anticoagulation use in patients with AF. METHODS: We identified incident AF in a 20% sample of fee-for-service Medicare beneficiaries (aged ≥ 65 years) from 2011 to 2016 and collected ZIP code and covariates at the time of AF. We identified the first anticoagulant prescription filled, if any, following AF diagnosis. We categorized beneficiaries into four rural/urban areas using rural-urban commuting area codes and used Poisson regression models to compare anticoagulant use. RESULTS: We included 447,252 patients with AF (mean age 79 ± 8 years), of which 82% were urban, 9% large rural, 5% small rural, and 4% isolated. The percentage who initiated an anticoagulant rose from 34% in 2011 to 53% in 2016, paralleling the uptake of DOACs. In a multivariable-adjusted analysis, those in rural areas (vs. urban) were more likely to initiate an anticoagulant. However, rural beneficiaries (vs. urban) were less likely to initiate a DOAC; those in isolated areas were 17% less likely (95% confidence interval [CI] 13-20), those in small rural areas were 12% less likely (95% CI 9-15), and those in large rural areas were 10% less likely (95% CI 8-12). CONCLUSION: Among Medicare beneficiaries with AF, anticoagulation use was low but increased over time with the introduction of DOACs. Rural beneficiaries were less likely to receive a DOAC.

The Learning Health System Competency Appraisal Inventory (LHS-CAI): A novel tool for assessing LHS-focused education needs.

There is increasing interest in health care organizations functioning as learning health systems (LHSs) to improve the quality and efficiency of health care delivery while generating new knowledge. Individuals must be trained in associated concepts and competencies and subsequently positioned (or embedded) within the delivery system for maximum effect as they perform their scholarship. Potential researchers within LHSs come from many different training backgrounds; therefore, each LHS scholar requires a goal-directed plan tailored to his or her needs. There are few tools available to guide development, training, or evaluation of individuals interested in becoming leaders of research in LHSs. In this paper, we present a newly developed tool for guiding the training of such researchers, the Learning Health Systems Competency Appraisal Inventory (LHS-CAI). The LHS-CAI is modeled after the Clinical Research Appraisal Index (CRAI) used within Clinical and Translational Science Award sites across the United States. The LHS-CAI is a tool for trainees at all levels to use with their mentors in an interactive manner. The tool can then identify areas in which more training is needed and at what level to ensure success as a researcher within LHSs. We further modified the CRAI format to better leverage the LHS-CAI as a key part of an LHS scholar's individual development plan. To implement the LHS-CAI, we have identified key points within the Minnesota Learning Health System Mentored Career Development Program (MN-LHS) at which assessment of expertise for each competency would be useful to LHS scholars, mentors, and program leaders. Scholars in this program come from various clinical and academic backgrounds but are all targeting their career trajectories toward leading embedded LHS research. They will reevaluate their expertise upon completion of the program, with comparison to baseline serving as a key program evaluation tool. The LHS-CAI is currently being implemented with the first cohort of scholars in the MN-LHS program.

Experiences with Work and Participation in Public Programs by Low-Income Medicaid Enrollees Using Qualitative Interviews.

BACKGROUND: Centers for Medicare & Medicaid Services (CMS) began encouraging governors to implement work requirements for Medicaid enrollees using section 1115 waivers in 2018. Significant controversy surrounds such attempts, but we know little about the perceptions and experiences of enrollees. OBJECTIVE: To characterize experiences of work and its relationship to participation in Medicaid and other public programs among potential targets of Medicaid work requirements. DESIGN: In-depth, semi-structured, one-time qualitative interviews. PARTICIPANTS: 35 very low-income, non-disabled Medicaid expansion enrollees participating in a county-sponsored Medicaid managed care plan as a part of a larger study. APPROACH: We used a biographical narrative interpretive method during interviews including questions about the use of employment and income support and other public programs including from state and federal disability programs. Our team iteratively coded verbatim transcripts allowing for emergent themes. KEY RESULTS: Interview data revealed high motivation for, and broad participation in, formal and informal paid work. Eight themes emerged: (1) critical poverty (for example, "I'm not content, but what choices do I have?"); (2) behavioral and physical health barriers to work; (3) social barriers: unstable housing, low education, criminal justice involvement; (4) work, pride, and shame; (5) inflexible, unstable work (for example, "Can I have a job that will accommodate my doctor appointments?…Will my therapy have to suffer? You know? So it's a double edged sword."); (6) Medicaid supports the ability to work; (7) lack of transparency and misalignment of program eligibility (for example, "It's not like I don't want to work because I would like to work. It's just that I don't want to be homeless again, right?"); and (8) barriers, confusion, and contradictions about federal disability. CONCLUSIONS: We conclude that bipartisan solutions prioritizing the availability of well-paying jobs and planful transitions off of public programs would best serve very low-income, work-capable Medicaid enrollees.

Evaluating Travel Distance to Radiation Facilities Among Rural and Urban Breast Cancer Patients in the Medicare Population.

PURPOSE: The distance patients travel for specialty care is an important barrier to health care access, particularly for those living in rural areas. This study characterizes the actual distance older breast cancer patients traveled to radiation treatment and the minimum distance necessary to reach radiation care, and examines whether any patient demographic or clinical factors are associated with greater travel distance. METHODS: We used data from the Surveillance Epidemiology and End Results (SEER)-Medicare database. Our cohort included 52,317 women diagnosed with breast cancer between 2004 and 2013. Driving distances were calculated using Google Maps. We used generalized estimating equations to estimate associations between patient demographic and disease variables and travel distance. FINDINGS: Patients living in rural areas traveled on average nearly 3 times as far as those from urban areas (40.8 miles vs 15.4 miles), and their nearest facility was more than 4 times farther away (21.9 miles vs 4.8 miles). Older age, being single or widowed, and lower household income were significantly associated with shorter actual travel distance, while increasing rurality was significantly associated with greater actual and minimum travel distance to radiation treatment. Disease severity (stage, grade, etc) was not significantly associated with actual or minimum travel distance. CONCLUSIONS: In this insured population, travel distance to radiation facilities may pose a significant burden for breast cancer patients, particularly among those living in rural areas. Policymakers and patient advocates should explore service delivery models, reimbursement models, and social supports aimed at reducing the impact of travel to radiation treatment for breast cancer patients.

Changes in Quality of Life Among Enrollees in Hennepin Health: A Medicaid Expansion ACO.

Despite limited program evaluations of Medicaid accountable care organizations (ACOs), no studies have examined if cost-saving goals negatively affect quality of life and health care experiences of low-income enrollees. The Hennepin Health ACO uses an integrated care model to address the physical, behavioral, and social needs of Medicaid expansion enrollees. As part of a larger evaluation, we conducted semistructured interviews with 35 primary care using Hennepin Health members enrolled for 2 or more years. Using fuzzy set qualitative comparative analysis, we assessed enrollee complexity and use of the care model and improvements in quality of life. We found improved quality of life was consistently associated with strong bonds to primary care, consistent mental health care, and support from extended care team members. Comprehensive, integrated care models within ACOs may improve quality of life for low-income Medicaid enrollees through coordinated primary and mental health care.

Integrated, Accountable Care For Medicaid Expansion Enrollees: A Comparative Evaluation of Hennepin Health.

Hennepin Health, a Medicaid accountable care organization, began serving early expansion enrollees (very low-income childless adults) in 2012. It uses an integrated care model to address social and behavioral needs. We compared health care utilization in Hennepin Health with other Medicaid managed care in the same area from 2012 to 2014, controlling for demographics, chronic conditions, and enrollment patterns. Homelessness and substance use were higher in Hennepin Health. Overall adjusted results showed Hennepin Health had 52% more emergency department visits and 11% more primary care visits than comparators. Over time, modeling a 6-month exposure to Hennepin Health, emergency department and primary care visits decreased and dental visits increased; hospitalizations decreased nonsignificantly but increased among comparators. Subgroup analysis of high utilizers showed lower hospitalizations in Hennepin Health. Integrated, accountable care under Medicaid expansion showed some desirable trends and subgroup benefits, but overall did not reduce acute health care utilization versus other managed care.

Development and Implementation of an Interdisciplinary Intensive Primary Care Clinic for High-Need High-Cost Patients in a Safety Net Hospital.

In 2010, payment for some of Hennepin County Medical Center's highest need patients changed from fee for service to a per capita formula. This financial stress led the institution to employ a population health lens that revealed a significant concentration of spending on a small segment of the population. Finding high rates of potentially avoidable inpatient and emergency care, an organizational effort was initiated to attempt to manage this high-need, high-cost population more effectively. A freestanding interdisciplinary intensive primary care clinic was developed. Nurses led a risk stratification process to identify eligible patients for co-located medical, care coordination, and social services from multidisciplinary care teams. Workflows to engage the population were designed to reduce readmissions and inappropriate use of emergency services. Soon after opening, the clinic added mental health and substance use professionals. For people entering the clinic between January 2010 and July 2017, utilization and financial data were collected for the year before (pre) and after (post) enrollment (n = 487). Bivariate statistics and outlier analyses facilitated comparisons between pre/post enrollment. Patients visited the new clinic twice per month on average and outpatient costs almost doubled. Overall costs were 16% lower, with the largest decrease seen in inpatient costs. This experience has led to ongoing investment, replication, and expansion of the model. An interdisciplinary intensive primary care clinic for high-utilizing, underserved patients is a promising intervention. Multidisciplinary teams and ongoing institutional support are critical to program success. Payment reform is essential to the development of such programs.

Long-Term Effects of Age Discrimination on Mental Health: The Role of Perceived Financial Strain.

OBJECTIVES: This study examines the role of work-related perceived age discrimination on women's mental health over the life course and tests whether financial strain mediates this relationship. METHODS: Using the National Longitudinal Survey of Mature Women (1967-2003), we employ nested growth curve models to evaluate whether perceived age discrimination at work influences women's depressive symptoms and life satisfaction and whether perceived financial strain mediates this relationship. RESULTS: Women who experienced age discrimination had greater overall depressive symptoms but not after controlling for financial strain. We found evidence that age discrimination affected financial strain, which, in turn, increased women's depressive symptoms. Women who reported age discrimination had lower odds of being in higher categories of overall life satisfaction; financial strain partially mediated the relationship but age discrimination remained a significant predictor. DISCUSSION: Despite legal protection, age discrimination at work is frequent and has significant effects on women's mental health over the life course. Financial strain partially mediates this relationship, pointing to financial implications of perceived age discrimination for women and their families. Our findings have important policy and workplace implications, calling attention to ageism as a potent stressor for working women's mental health beyond those tied to sex or race.

Quasi-Experimental Evaluation of LifeCourse on Utilization and Patient and Caregiver Quality of Life and Experience.

Whole-person care is a new paradigm for serious illness, but few programs have been robustly studied. We sought to test the effect of LifeCourse (LC), a person-centered program for patients living with serious illness, on health-care utilization, care experience, and quality of life, employing a quasi-experimental design with a Usual Care (UC) comparison group. The study was conducted 2012 to 2017 at an upper-Midwest not-for-profit health-care system with outcomes measured every 3 months until the end of life. Enrolled patients (N = 903) were estimated to be within 3 years of end of life and diagnosed with 1+ serious illness. Exclusion criteria included hospice enrollment at time of screening or active dying. Community health workers (CHWs) delivered standardized monthly 1-hour home visits based on palliative care guidelines and motivational interviewing to promote patients' physical, psychosocial, and financial well-being. Primary outcomes included health-care utilization and patient- and caregiver-experience and quality of life. Patients were elderly (LC 74, UC 78 years) and primarily non-Hispanic, white, living at home with cardiovascular disease as the primary diagnosis (LC 69%, UC 57%). A higher proportion of LC patients completed advance directives (N = 173, 38%) than UC patients (N = 66, 15%; P < .001). LifeCourse patients who died spent more days in hospice (88 ± 191 days) compared to UC patients (44 ± 71 days; P = .018). LifeCourse patients reported greater improvements than UC in communication as part of the care experience ( P = .016). Implementation of person-centered programs delivered by CHWs is feasible; inexpensive upstream expansion of palliative care models can yield benefits for patients and caregivers. Trial Registration: Trial NCT01746446 was registered on November 27, 2012 at ClinicalTrials.gov .

The Complex Needs of Medicaid Expansion Enrollees with Very Low Incomes.

Issue: Access to health care, use of services, and patient outcomes can be complicated by many medical and nonmedical factors. People facing complex challenges such as mental illness, housing insecurity, or substance use, however, are not a homogeneous group; different individuals have different needs. Goals: To understand the needs of people with very low income--no more than 75 percent of the federal poverty level--who enrolled in Medicaid under Minnesota's expansion of the program prior to the Affordable Care Act. Methods: The authors analyzed data on nondisabled, childless adults in the Minneapolis-St. Paul region who enrolled in Medicaid between 2011 and 2013. Findings and Conclusions: Early Medicaid expansion enrollees in urban Minnesota were largely nonwhite, male, and unmarried and had low educational attainment. In this very poor population, rates of homelessness, substance use, and mental illness were very high. More than 25 percent of adults dealt with two or more of these challenges, while 10 percent experienced all three. Providing access to a range of highly integrated health and social services may be the best way to help these individuals.

Acupuncture 'dose' (number of treatments) and insurance benefits in the USA.

BACKGROUND: An adequate treatment dose, including a sufficient number of acupuncture treatments, is important for the clinical effectiveness of acupuncture treatment for common conditions. OBJECTIVE: To examine the characteristics of US adults who used a full course of acupuncture (≥6 treatments), a short course (1-5 treatments) or no acupuncture, including use of insurance benefits for acupuncture among users. METHODS: We used population-based survey data from the 2012 National Health Interview Survey (NHIS), the most current nationally representative data including use of acupuncture. We described subgroups of acupuncture users and used logistic regression to estimate the odds of past year acupuncture use versus non-use and completion of a full treatment course versus a short course. Covariates included demographic factors and health status. Analyses used strata, weights and clustering to account for the complex sample design. RESULTS: Among acupuncture users, 38% completed a full course. Acupuncture use was low (1.5%), but odds were higher among women and those with greater education and less poverty. Those who used acupuncture insurance benefits and who had greater education were more likely to receive a full treatment course. Insurance benefits attenuated disparities in use by sex and race/ethnicity. CONCLUSION: Nationally, most people who use acupuncture do not receive a full treatment course. Considering evidence of effectiveness, low risk and relatively low cost of delivery, acupuncture could play a larger role in non-pharmaceutical treatment of common conditions such as pain. Policymakers should consider that, without insurance benefits for acupuncture, people are less likely to complete a full treatment course, which may contribute to disparities in use and health outcomes.

Evaluation of Amphetamine-Related Hospitalizations and Associated Clinical Outcomes and Costs in the United States.

Importance: Despite indications of increasing amphetamine availability and psychostimulant deaths in the United States, evidence across data sources is mixed, and data on amphetamine-related hospitalizations are lacking. Objective: To clarify trends in amphetamine-related hospitalizations and their clinical outcomes and costs in the United States. Design, Setting, and Participants: This repeated, cross-sectional study used hospital discharge data from the Healthcare Cost and Utilization Project National Inpatient Sample. The nationally representative sample included US adults (n = 1 292 300) who had amphetamine-related hospitalizations between January 1, 2003, and December 31, 2015. Multivariable logistic and Poisson regression models were used to examine in-hospital mortality and length of stay. Analysis of these data was conducted from November 2017 to August 2018. Exposure: Amphetamine dependence or abuse or amphetamine poisoning. Main Outcomes and Measures: Annual hospitalizations, in-hospital mortality, length of stay, transfer to another facility, and costs. Results: Over the 2003 to 2015 study period, there were 1 292 300 weighted amphetamine-related hospitalizations. Of this population, 541 199 (41.9%) were female and 749 392 (58.1%) were male, with a mean age of 37.5 years (95% CI, 37.4-37.7 years). Amphetamine-related hospitalizations, compared with other hospitalizations, were associated with age younger than 65 years (98.0% vs 58.0%; P < .001), male sex (60.3% [95% CI, 59.7%-60.8%] vs 41.1% [95% CI, 40.9%-41.3%]), Medicaid coverage (51.2% [95% CI, 49.8%-52.7%] vs 17.8% [95% CI, 17.5%-18.1%]), and residence in the western United States (58.5% [95% CI, 55.9%-61.0%] vs 18.9% [95% CI, 18.0%-19.8%]). Amphetamine-related hospitalizations declined between 2005 and 2008, and then increased from 55 447 hospitalizations (95% CI, 44 936-65 959) in 2008 to 206 180 hospitalizations (95% CI, 95% CI, 189 188-223 172) in 2015. Amphetamine-related hospitalizations increased to a greater degree than hospitalizations associated with other substances. Adjusted mean length of stay (5.9 [95% CI, 5.8-6.0] vs 4.7 [95% CI, 4.7-4.8] days; P < .001), transfer to another facility (26.0% [95% CI, 25.3%-26.8%] vs 18.5% [95% CI, 18.3%-18.6%]; P < .001), and mean in-hospital mortality (28.3 [95% CI, 26.2-30.4] vs 21.9 [95% CI, 21.6-22.1] deaths per 1000 hospitalizations; P < .001) were higher for amphetamine-related than other hospitalizations. Annual hospital costs related to amphetamines increased from $436 million (95% CI, $312 million-$559 million) in 2003 to $2.17 billion (95% CI, $1.95 billion-$2.39 billion) by 2015. Conclusions and Relevance: Given that amphetamine-related hospitalizations and costs substantially increased between 2003 and 2015, pharmacologic and nonpharmacologic therapies for amphetamine use disorders and a coordinated public health response are needed to curb these rising rates.

Identifying Homeless Medicaid Enrollees Using Enrollment Addresses.

OBJECTIVE: To design and test the validity of a method to identify homelessness among Medicaid enrollees using mailing address data. DATA SOURCES/STUDY SETTING: Enrollment and claims data on Medicaid expansion enrollees in Hennepin and Ramsey counties who also provided self-reported information on their current housing situation in a psychosocial needs assessment. STUDY DESIGN: Construction of address-based indicators and comparison with self-report data. PRINCIPAL FINDINGS: Among 1,677 enrollees, 427 (25 percent) self-reported homelessness, of whom 328 (77 percent) had at least one positive address indicator. Depending on the type of addresses included in the indicator, sensitivity to detect self-reported homelessness ranged from 30 to 76 percent and specificity from 79 to 97 percent. CONCLUSIONS: An address-based indicator can identify a large proportion of Medicaid enrollees who are experiencing homelessness. This approach may be of interest to researchers, states, and health systems attempting to identify homeless populations.

Patient capacity and constraints in the experience of chronic disease: a qualitative systematic review and thematic synthesis.

BACKGROUND: Life and healthcare demand work from patients, more so from patients living with multimorbidity. Patients must respond by mobilizing available abilities and resources, their so-called capacity. We sought to summarize accounts of challenges that reduce patient capacity to access or use healthcare or to enact self-care while carrying out their lives. METHODS: We conducted a systematic review and synthesis of the qualitative literature published since 2000 identifying from MEDLINE, EMBASE, Psychinfo, and CINAHL and retrieving selected abstracts for full text assessment for inclusion. After assessing their methodological rigor, we coded their results using a thematic synthesis approach. RESULTS: The 110 reports selected, when synthesized, showed that patient capacity is an accomplishment of interaction with (1) the process of rewriting their biographies and making meaningful lives in the face of chronic condition(s); (2) the mobilization of resources; (3) healthcare and self-care tasks, particularly, the cognitive, emotional, and experiential results of accomplishing these tasks despite competing priorities; (4) their social networks; and (5) their environment, particularly when they encountered kindness or empathy about their condition and a feasible treatment plan. CONCLUSION: Patient capacity is a complex and dynamic construct that exceeds "resources" alone. Additional work needs to translate this emerging theory into useful practice for which we propose a clinical mnemonic (BREWS) and the ICAN Discussion Aid.

Pursuing minimally disruptive medicine: disruption from illness and health care-related demands is correlated with patient capacity.

BACKGROUND: Chronic conditions burden patients with illness and treatments. We know little about the disruption of life by the work of dialysis in relation to the resources patients can mobilize, that is, their capacity, to deal with such demands. We sought to determine the disruption of life by dialysis and its relation to patient capacity to cope. METHODS: We administered a survey to 137 patients on dialysis at an academic medical center. We captured disruption from illness and treatment, and physical, mental, personal, social, financial, and environmental aspects of patient capacity using validated scales. Covariates included number of prescriptions, hours spent on health care, existence of dependents, age, sex, and income level. RESULTS: On average, patients reported levels of capacity and disruption comparable to published levels. In multivariate regression models, limited physical, financial, and mental capacity were significantly associated with greater disruption. Patients in the top quartile of disruption had lower-than-expected physical, financial, and mental capacity. CONCLUSIONS: Our sample generally had capacity comparable to other populations and may be able to meet the demands imposed by treatment. Those with reduced physical, financial, and mental capacity reported higher disruption and represent a vulnerable group that may benefit from innovations in minimally disruptive medicine.

Experiences With Insurance Plans and Providers Among Persons With Mental Illness.

OBJECTIVE: This study used nationally representative household survey data to examine the association between mental illness and experiences with usual care providers and health plans among persons with public or private insurance (N=25,176). METHODS: Data were from the 2004-2012 Medical Expenditure Panel Surveys. Mental illness was assessed with symptom scales of serious psychological distress and depression at two time points, and persons were categorized by whether mental illness was episodic or persistent over time. Questions about experiences with providers (four questions) and plans (five questions) were based on the Consumer Assessment of Healthcare Providers and Systems survey. Rates of problems with plans and providers were reported for each category of mental illness, and multivariate regression was used to examine the association of problems with mental illness. RESULTS: Rates of problems with health plans were high, specifically for treatment approvals, finding information, and customer service, and were higher among persons with mental illness. Rates of problems with providers were lower than problems with plans, but persons with mental illness were more likely to report problems, specifically that doctors do not explain treatment options, respect treatment choices, or seek participation in decisions. CONCLUSIONS: Persons with mental illness reported experiencing more clinical and administrative problems at their usual source of care, although the reasons were not clear. Efforts by plans to improve health care before and after the clinical encounter and by providers to design treatments in line with patient preferences may improve experiences for all patients and particularly for those with mental illness.

An observational study of emergency department utilization among enrollees of Minnesota Health Care Programs: financial and non-financial barriers have different associations.

BACKGROUND: Emergency department (ED) use is costly, and especially frequent among publicly insured populations in the US, who also disproportionately encounter financial (cost/coverage-related) and non-financial/practical barriers to care. The present study examines the distinct associations financial and non-financial barriers to care have with patterns of ED use among a publicly insured population. METHODS: This observational study uses linked administrative-survey data for enrollees of Minnesota Health Care Programs to examine patterns in ED use-specifically, enrollee self-report of the ED as usual source of care, and past-year count of 0, 1, or 2+ ED visits from administrative data. Main independent variables included a count of seven enrollee-reported financial concerns about healthcare costs and coverage, and a count of seven enrollee-reported non-financial, practical barriers to access (e.g., limited office hours, problems with childcare). Covariates included health, health care, and demographic measures. RESULTS: In multivariate regression models, only financial concerns were positively associated with reporting ED as usual source of care, but only non-financial barriers were significantly associated with greater ED visits. Regression-adjusted values indicated notable differences in ED visits by number of non-financial barriers: zero non-financial barriers meant an adjusted 78% chance of having zero ED visits (95% C.I.: 70.5%-85.5%), 15.9% chance of 1(95% C.I.: 10.4%-21.3%), and 6.2% chance (95% C.I.: 3.5%-8.8%) of 2+ visits, whereas having all seven non-financial barriers meant a 48.2% adjusted chance of zero visits (95% C.I.: 30.9%-65.6%), 31.8% chance of 1 visit (95% C.I.: 24.2%-39.5%), and 20% chance (95% C.I.: 8.4%-31.6%) of 2+ visits. CONCLUSIONS: Financial barriers were associated with identifying the ED as one's usual source of care but non-financial barriers were associated with actual ED visits. Outreach/literacy efforts may help reduce reliance on/perception of ED as usual source of care, whereas improved targeting/availability of covered services may help curb frequent actual visits, among publicly insured individuals.

'They leave at least believing they had a part in the discussion': understanding decision aid use and patient-clinician decision-making through qualitative research.

OBJECTIVE: This study explores how patient decision aids (DAs) for antihyperglycemic agents and statins, designed for use during clinical consultations, are embedded into practice, examining how patients and clinicians understand and experience DAs in primary care visits. METHODS: We conducted semistructured in-depth interviews with patients (n=22) and primary care clinicians (n=19), and videorecorded consultations (n=44). Two researchers coded all transcripts. Inductive analyses guided by grounded theory led to the identification of themes. Video and interview data were compared and organized by themes. RESULTS: DAs used during consultations became flexible artifacts, incorporated into existing decision making roles for clinicians (experts, authority figures, persuaders, advisors) and patients (drivers of healthcare, learners, partners). DAs were applied to different decision making steps (deliberation, bargaining, convincing, case assessment), and introduced into an existing knowledge context (participants' literacy regarding shared decision-making (SDM) and DAs). CONCLUSION: DAs' flexible use during consultations effectively provided space for discussion, even when SDM was not achieved. DAs can be used within any decision-making model. PRACTICE IMPLICATIONS: Clinician training in DA use and SDM practice may be needed to facilitate DA implementation and promote more ideal-type forms of sharing in decision making.

Diagnosed prevalence and health care expenditures of mental health disorders among dual eligible older people.

PURPOSE: Little is known about mental health disorders (MHDs) and their associated health care expenditures for the dual eligible elders across long-term care (LTC) settings. We estimated the 12-month diagnosed prevalence of MHDs among dual eligible older adults in LTC and non-LTC settings and calculated the average incremental effect of MHDs on medical care, LTC, and prescription drug expenditures across LTC settings. METHODS: Participants were fee-for-service dual eligible elderly beneficiaries from 7 states. We obtained their 2005 Medicare and Medicaid claims data and LTC program participation data from federal and state governments. We grouped beneficiaries into non-LTC, community LTC, and institutional LTC groups and identified enrollees with any of 5 MHDs (anxiety, bipolar, major depression, mild depression, and schizophrenia) using the International Classification of Diseases Ninth Revision codes associated with Medicare and Medicaid claims. We obtained medical care, LTC, and prescription drug expenditures from related claims. RESULTS: Thirteen percent of all dual eligible elderly beneficiaries had at least 1 MHD diagnosis in 2005. Beneficiaries in non-LTC group had the lowest 12-month prevalence rates but highest percentage increase in health care expenditures associated with MHDs. Institutional LTC residents had the highest prevalence rates but lowest percentage increase in expenditures. LTC expenditures were less affected by MHDs than medical and prescription drug expenditures. IMPLICATIONS: MHDs are prevalent among dual eligible older persons and are costly to the health care system. Policy makers need to focus on better MHD diagnosis among community-living elders and better understanding in treatment of MHDs in LTC settings.

Hospitalization costs for radical prostatectomy attributable to robotic surgery.

BACKGROUND: With health technology innovation responsible for higher health care costs, it is essential to have accurate estimates regarding the differential costs between robot-assisted radical prostatectomy (RARP) and open radical prostatectomy (ORP). OBJECTIVE: To describe the total hospitalization costs attributable to robotic and open surgery for radical prostatectomy (RP). DESIGN, SETTING, AND PARTICIPANTS: Using a population-based cohort by merging the Nationwide Inpatient Sample (NIS) and the American Hospital Association (AHA) survey from 2006 to 2008, we identified 29 837 prostate cancer patients who underwent RP. INTERVENTIONS: ORP and RARP. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary outcome was total hospitalization costs adjusted to year 2008 US dollars. Generalized estimating equations were used to identify patient and hospital characteristics associated with total hospitalization costs and to estimate costs of ORP and RARP adjusted for case mix and hospital teaching status, location, and annual case volume. RESULTS AND LIMITATIONS: Overall, 20 424 (68.5%) patients were surgically treated with RARP, and 9413 (31.5%) patients underwent ORP. Compared to ORP, patients undergoing RARP had shorter median length of stay (1 d vs 2 d; p<0.001) and were less likely to experience any postoperative complications (8.2% vs 11.3%; p<0.001). However, patients undergoing RARP had higher median hospitalization costs ($10409 vs $8862; p<0.001). After adjusting for patient and hospital features, RARP was associated with higher total hospitalization costs compared to ORP ($11932 vs $9390; p<0.001). Our results are limited by a study design using retrospective population-based data. CONCLUSIONS: Despite RARP having lower complications and shorter length of stay than ORP, total hospitalization costs are higher for patients treated with RARP compared with those treated with ORP.
