Clinical Decision Support Systems to Reduce Unnecessary Clostridioides difficile Testing Across Multiple Hospitals.

BACKGROUND: Inappropriate Clostridioides difficile testing has adverse consequences for patients, hospitals, and public health. Computerized clinical decision support (CCDS) systems in the electronic health record (EHR) may reduce C. difficile test ordering; however, effectiveness of different approaches, ease of use, and best fit into healthcare providers' (HCP) workflow are not well understood. METHODS: Nine academic and 6 community hospitals in the United States participated in this 2-year cohort study. CCDS (hard stop or soft stop) triggered when a duplicate C. difficile test order was attempted or if laxatives were recently received. The primary outcome was the difference in testing rates pre- and post-CCDS interventions, using incidence rate ratios (IRRs) and mixed-effect Poisson regression models. We performed qualitative evaluation (contextual inquiry, interviews, focus groups) based on a human factors model. We identified themes using a codebook with primary nodes and subnodes. RESULTS: In 9 hospitals implementing hard-stop CCDS and 4 hospitals implementing soft-stop CCDS, C. difficile testing incidence rate (IR) reduction was 33% (95% confidence interval [CI]: 30%-36%) and 23% (95% CI: 21%-25%), respectively. Two hospitals implemented a non-EHR-based human intervention with IR reduction of 21% (95% CI: 15%-28%). HCPs reported generally favorable experiences and highlighted time efficiencies such as inclusion of the patient's most recent laxative administration on the CCDS. Organizational factors, including hierarchical cultures and communication between HCPs caring for the same patient, impact CCDS acceptance and integration. CONCLUSIONS: CCDS systems reduced unnecessary C. difficile testing and were perceived positively by HCPs when integrated into their workflow and when displaying relevant patient-specific information needed for decision making.

Barriers and facilitators to depression screening in older adults: a qualitative study.

Objectives: The objective of this qualitative study was to better understand facilitators and barriers to depression screening for older adults.Methods: We conducted 43 focus groups with 102 providers and 247 beneficiaries or proxies: 13 focus groups with Medicare providers, 28 with older Medicare beneficiaries, and 2 with caregivers of older Medicare beneficiaries. Each focus group was recorded, transcribed, and analyzed using principles of grounded theory.Results: There was widespread consensus among beneficiary and provider focus group participants that depression screening was important. However, several barriers interfered with effective depression screening, including stigma, lack of resources for treatment referrals, and lack of time during medical encounters. Positive communication with providers and an established relationship with a trusted provider were primary facilitators for depression screening. Providers who took the time to put their beneficiaries at ease and used conversational language rather than clinical terms appeared to have the most success in eliciting beneficiary honesty about depressive symptoms. Respondents stressed the need for providers to be attentive, concerned, non-judgmental, and respectful.Conclusion: Findings indicate that using person-centered approaches to build positive communication and trust between beneficiaries and providers could be an effective strategy for improving depression screening. Better screening can lead to higher rates of diagnosis and treatment of depression that could enhance quality of life for older adults.

Facilitators and barriers to optimal preventive service use among providers and older patients.

Preventive service use remains low among Medicare beneficiaries despite the Affordable Care Act's waiver of coinsurance. This study sought to understand barriers and facilitators to preventive service provision, access, and uptake. We used a mixed methods approach synthesizing quantitative survey and qualitative focus group data. Self-reported utilization of and factors related to preventive services were explored using quantitative data from the 2012 Medicare Current Beneficiary Survey. Qualitative data from 16 focus groups conducted in 2016 with a range of providers, health advocates, and Medicare beneficiaries explored perspectives on preventive service use. Providers indicated time and competing priorities as factors for not offering patients a full range of preventive services, while beneficiaries reported barriers related to knowledge, perception, and trust. Current healthcare reform efforts incorporating team-based care, nurses and other non-physician providers, and coordinated electronic health records could support enhanced use of preventive services if fully implemented and utilized.

Operationalizing Surveillance of Chronic Disease Self-Management and Self-Management Support.

Sixty percent of US adults have at least one chronic condition, and more than 40% have multiple conditions. Self-management (SM) by the individual, along with self-management support (SMS) by others, are nonpharmacological interventions with few side effects that are critical to optimal chronic disease control. Ruiz and colleagues laid the conceptual groundwork for surveillance of SM/SMS at 5 socio-ecological levels (individual, health system, community, policy, and media). We extend that work by proposing operationalized indicators at each socio-ecologic level and suggest that the indicators be embedded in existing surveillance systems at national, state, and local levels. Without a robust measurement system at the population level, we will not know how far we have to go or how far we have come in making SM and SMS a reality. The data can also be used to facilitate planning and service delivery strategies, monitor temporal changes, and stimulate SM/SMS-related research.

Two Innovative Cancer Care Programs Have Potential to Reduce Utilization and Spending.

BACKGROUND: Cancer patients often present to the emergency department (ED) and hospital for symptom management, but many of these visits are avoidable and costly. OBJECTIVE: We assessed the impact of 2 Health Care Innovation Awards that used an oncology medical home model [Community Oncology Medical Home (COME HOME)] or patient navigation model [Patient Care Connect Program (PCCP)] on utilization and spending. METHODS: Participants in COME HOME and PCCP models were matched to similar comparators using propensity scores. We analyzed utilization and spending outcomes using Medicare fee-for-service claims with unadjusted and adjusted difference-in-differences models. RESULTS: In the adjusted models, both COME HOME and PCCP were associated with fewer ED visits than a comparison group (15 and 22 per 1000 patients/quarter, respectively; P<0.01). In addition, COME HOME had lower spending ($675 per patient/quarter; P<0.01), and PCCP had fewer hospitalizations (11 per 1000 patients/quarter; P<0.05), relative to the comparison group. Among patients undergoing chemotherapy, fewer COME HOME and PCCP patients had ED visits (18 and 28 per 1000 patients/quarter, respectively; P<0.01) and fewer PCCP patients had hospitalizations (13 per 1000 patients/quarter; P<0.05), than comparison patients. CONCLUSIONS: The oncology medical home and patient navigator programs both showed reductions in spending or utilization. Adoption of such programs holds promise for improving cancer care.

Risk Factors for Persistent Frequent Emergency Department Use in Medicare Beneficiaries.

STUDY OBJECTIVE: We examine factors associated with persistent frequent emergency department (ED) use during a 2-year period among Medicare beneficiaries. METHODS: We conducted a retrospective, claims-based analysis of fee-for-service Medicare beneficiaries, using the Chronic Condition Data Warehouse's random 20% sample files. We used multinomial logistic regression models to compare frequent ED use (defined as 4 or more ED visits per year) with infrequent use (1 to 3 visits per year), non-ED use, and death in 2010 as a function of sociodemographic, primary care, clinical characteristics, and 2009 ED use. RESULTS: Approximately 1.1% of Medicare beneficiaries were persistent frequent ED users, defined as experiencing frequent ED use in 2009 and 2010 consecutively. Of the 3.3% of Medicare beneficiaries who were frequent ED users in 2009, 34.3% were frequent ED users, 19.4% were non-ED users, 39.0% were infrequent ED users, and 7.4% died in 2010. Frequent ED use in 2009 was highly associated with frequent ED use in 2010 (relative risk ratio 35.2; 95% confidence interval 34.5 to 35.8). Younger age, Medicaid status, and mental illness were also strong predictors of frequent ED use. The probability of frequent ED use in 2010 was 3.4% for the total sample, but was 19.4% for beneficiaries who were frequent users in 2009 and 49.0% for beneficiaries in the youngest age group who had mental illness, Medicaid, and frequent ED use in 2009. CONCLUSION: Efforts to curtail frequent ED use in Medicare should focus on disabled, socially vulnerable beneficiaries.

Characteristics of Markets and Patients Served by ESRD Seamless Care Organizations.

Under the Comprehensive End-stage Renal Disease (ESRD) Care (CEC) Model, dialysis facilities and nephrologists form ESRD Seamless Care Organizations (ESCOs) to deliver high value care. This study compared the characteristics of patients and markets served and unserved by CEC and assessed its generalizability. ESCOs operated in 65 of 384 markets. ESCO markets were larger than non-ESCO markets, had fewer White patients, higher household income, and higher Medicare spending per patient. Patients in ESCOs were similar to eligible nonaligned patients in age and sex but differed in race/ethnicity and were more often treated in an urban area; comorbidity prevalence differed modestly. CEC is available to a meaningful share of the dialysis population and relatively few dialysis patients resided in a market where no provider could meet the participation threshold, so market size may not be the primary barrier for potential new participants in CEC or future kidney care models.

Association of the Comprehensive End-Stage Renal Disease Care Model With Medicare Payments and Quality of Care for Beneficiaries With End-Stage Renal Disease.

Importance: Medicare beneficiaries with end-stage renal disease (ESRD) are a medically complex group accounting for less than 1% of the Medicare population but more than 7% of Medicare fee-for-service payments. Objective: To evaluate the association of the Comprehensive End-Stage Renal Disease Care (CEC) model with Medicare payments, health care use, and quality of care. Design, Setting, and Participants: In this economic evaluation, a difference-in-differences design estimated the change in outcomes for 73 094 Medicare fee-for-service beneficiaries aligned to CEC dialysis facilities between the baseline (from January 2014 to March 2015) and intervention periods (from October 2015 to December 2017) relative to 60 464 beneficiaries at matched dialysis facilities. In the CEC model, dialysis facilities, nephrologists, and other providers partner to form ESRD Seamless Care Organizations (ESCOs), specialty-oriented accountable care organizations that coordinate care for beneficiaries with ESRD. ESCOs with expenditures below a benchmark set by the Centers for Medicare & Medicaid Services are eligible to share in savings if they meet quality thresholds. A total of 685 dialysis facilities affiliated with 37 ESCOs participated in the CEC model as of January 2017. Thirteen ESCOs joined the CEC model on October 1, 2015 (wave 1), and 24 ESCOs joined on January 1, 2017 (wave 2). Patients with ESRD who were aligned with CEC dialysis facilities were compared with patients at matched dialysis facilities. Main Outcomes and Measures: Medicare total and service-specific payments per beneficiary per month; hospitalizations, readmissions, and emergency department visits; and select quality measures. Results: Relative to the comparison group (n = 60 464; 55% men; mean [SD] age, 63.5 [14.4] years), total Medicare payments for CEC beneficiaries (n = 73 094; 56% men; mean [SD] age, 63.0 [14.4] years) decreased by $114 in payments per beneficiary per month (95% CI, -$202 to -$26; P = .01), associated primarily with decreases in payments for hospitalizations and readmissions. Payment reductions were offset by shared savings payments to ESCOs, resulting in net losses of $78 in payments per beneficiary per month (95% CI, -$8 to $164; P = .07). Relative to the comparison group, CEC beneficiaries had 5.01 fewer hospitalizations per 1000 beneficiaries per month (95% CI, -8.45 to -1.56; P = .004), as well as fewer catheter placements (CEC beneficiaries with catheter as vascular access for periods longer than 90 days decreased by 0.78 percentage points [95% CI, -1.36 to -0.19; P = .01]) and fewer hospitalizations for ESRD complications (CEC beneficiaries were 0.11 percentage points less likely [95% CI, -0.20 to -0.02; P = .01] to be hospitalized in a given month). Total dialysis sessions and payments increased, suggesting improved adherence to dialysis treatments. Conclusions and Relevance: Early findings from the CEC model demonstrate that a specialty accountable care organization model focused on a particular population was associated with reduced payments and improved quality of care. Future research can assess the longer-term outcomes of the CEC model and its applicability to populations with other complex chronic conditions.

Health Care Utilization and Cost Outcomes of a Comprehensive Dementia Care Program for Medicare Beneficiaries.

Importance: An estimated 4 to 5 million Americans have Alzheimer disease or another dementia. Objective: To determine the health care utilization and cost outcomes of a comprehensive dementia care program for Medicare fee-for-service beneficiaries. Design, Setting, and Participants: In this case-control study, we used a quasiexperimental design to compare health care utilization and costs for 1083 Medicare fee-for-service beneficiaries enrolled in the University of California Los Angeles Health System Alzheimer and Dementia Care program between July 1, 2012, and December 31, 2015, with those of 2166 similar patients with dementia not participating in the program. Patients in the comparison cohort were selected using the zip code of residence as a sampling frame and matched with propensity scores, which included demographic characteristics, comorbidities, and prior-year health care utilization. We used Medicare claims data to compare utilization and cost outcomes for the 2 groups. Interventions: Patients in the dementia care program were comanaged by nurse practitioners and physicians, and the program consisted of structured needs assessments of patients and their caregivers, creation and implementation of individualized dementia care plans with input from primary care physicians, monitoring and revising care plans, referral to community organizations for dementia-related services and support, and access to a clinician for assistance and advice 24 hours per day, 7 days per week. Main Outcomes and Measures: Admissions to long-term care facilities; average difference-in-differences per quarter over the 3-year intervention period for all-cause hospitalization, emergency department visits, 30-day hospital readmissions, and total Medicare Parts A and B costs of care. Program costs were included in the cost estimates. Results: Program participants (n = 382 men, n = 701 women; mean [SD] age, 82.10 [7.90] years; age range 54-101 years) were less likely to be admitted to a long-term care facility (hazard ratio, 0.60; 95% CI, 0.59-0.61) than those not participating in the dementia care program (n = 759 men, n = 1407 women; mean [SD] age, 82.42 [8.50] years; age range, 34-103 years). There were no differences between groups in terms of hospitalizations, emergency department visits, or 30-day readmissions. The total cost of care to Medicare, excluding program costs, was $601 less per patient per quarter (95% CI, -$1198 to -$5). After accounting for the estimated program costs of $317 per patient per quarter, the program was cost neutral for Medicare, with an estimated net cost of -$284 (95% CI, -$881 to $312) per program participant per quarter. Conclusions and Relevance: Comprehensive dementia care may reduce the number of admissions to long-term care facilities, and depending on program costs, may be cost neutral or cost saving. Wider implementation of such programs may help people with dementia stay in their communities.

The Impact of Enhanced Critical Care Training and 24/7 (Tele-ICU) Support on Medicare Spending and Postdischarge Utilization Patterns.

OBJECTIVE: To estimate the effect of implementing a tele-ICU and a critical care residency training program for advanced practice providers on service utilization and total Medicare episode spending. DATA SOURCES/STUDY SETTINGS: Medicare claims data for fee-for-service beneficiaries at 12 large, inpatient hospitals in the Atlanta Hospital Referral Region. STUDY DESIGN: Difference-in-differences design where changes in spending and utilization for Medicare beneficiaries eligible for treatment in participating ICUs was compared to changes in a comparison group of clinically similar beneficiaries treated at similar hospitals' ICUs in the same hospital referral region. EXTRACTION METHODS: Using Medicare claims data from January 2010 through June 2015, we defined measures of Medicare episode spending during the ICU stay and subsequent 60 days after discharge, and utilization measures within 30 and 60 days after discharge. PRINCIPAL FINDINGS: Implementation of the advanced practice provider residency program and tele-ICU was associated with a significant reduction in average Medicare spending per episode, primarily driven by reduced readmissions within 60 days and substitution of home health care for institutional postacute care. CONCLUSIONS: Innovations in workforce training and technology specific to the ICU may be useful in addressing the shortage of intensivist physicians, yielding benefits to patients and payers.

Factors Associated With Frequent Emergency Department Use in the Medicare Population.

Frequent emergency department (ED) use is a public health and policy relevant concern but has not previously been examined in the Medicare population. We conducted a retrospective, claims-based analysis of a nationally representative 20% sample of fee-for-service Medicare beneficiaries in 2010 ( n = 5,778,038) to examine frequent ED use. We used multinomial logistic regression to study the relationship between frequent ED use and sociodemographic, outpatient care, and clinical characteristics. Factors that were most strongly associated with frequent ED use included being age 18 to 34 years compared with 65 to 74 years (relative risk ratio = 20.5, confidence interval [CI; 19.7, 21.3]) and mental illness (relative risk ratio = 6.8, CI [6.7, 6.9]). Low versus high continuity of care was associated with 24% (95% CI [1.21, 1.26]) greater risk of frequent compared with non-ED use. Although clinical and demographic characteristics are most strongly associated with frequent ED use, poor continuity of care is also a contributor.

Innovative Home Visit Models Associated With Reductions In Costs, Hospitalizations, And Emergency Department Use.

While studies of home-based care delivered by teams led by primary care providers have shown cost savings, little is known about outcomes when practice-extender teams-that is, teams led by registered nurses or lay health workers-provide home visits with similar components (for example, care coordination and education). We evaluated findings from five models funded by Health Care Innovation Awards of the Centers for Medicare and Medicaid Services. Each model used a mix of different components to strengthen connections to primary care among fee-for-service Medicare beneficiaries with multiple chronic conditions; these connections included practice-extender home visits. Two models achieved significant reductions in Medicare expenditures, and three models reduced utilization in the form of emergency department visits, hospitalizations, or both for beneficiaries relative to comparators. These findings present a strong case for the potential value of home visits by practice-extender teams to reduce Medicare expenditures and service use in a particularly vulnerable and costly segment of the Medicare population.

Innovative Oncology Care Models Improve End-Of-Life Quality, Reduce Utilization And Spending.

Three models that received Health Care Innovation Awards from the Centers for Medicare and Medicaid Services (CMS) aimed to reduce the cost and use of health care services and improve the quality of care for Medicare beneficiaries with cancer. Each emphasized a different principle: the oncology medical home, patient navigation, or palliative care. Comparing participants in each model who died during the study period to matched comparators, we found that the oncology medical home and patient navigation models were associated with decreased costs in the last ninety days of life ($3,346 and $5,824 per person, respectively) and fewer hospitalizations in the last thirty days of life (fifty-seven and forty per 1,000 people, respectively). The patient navigation model was also associated with fewer emergency department visits in the last thirty days of life and increased hospice enrollment in the last two weeks of life. These promising results can inform new initiatives for cancer patients, such as the CMS Oncology Care Model.

Physician Engagement Strategies in Care Coordination: Findings from the Centers for Medicare & Medicaid Services' Health Care Innovation Awards Program.

OBJECTIVE: To identify roles physicians assumed as part of new health care delivery models and related strategies that facilitated physician engagement across 21 Health Care Innovation Award (HCIA) programs. DATA SOURCES: Site-level in-depth interviews, conducted from 2014 to 2015 (N = 672) with program staff, leadership, and partners (including 95 physicians) and direct observations. STUDY DESIGN: NORC conducted a mixed-method evaluation, including two rounds of qualitative data collected via site visits and telephone interviews. DATA COLLECTION/EXTRACTION METHODS: We used qualitative thematic coding for data from 21 programs actively engaging physicians as part of HCIA interventions. PRINCIPAL FINDINGS: Establishing physician champions and ensuring an innovation-values fit between physicians and programs, including the strategies programs employed, facilitated engagement. Among engagement practices identified in this study, tailoring team working styles to meet physician preferences and conducting physician outreach and education were the most common successful approaches. CONCLUSIONS: We describe engagement strategies derived from a diverse range of programs. Successful programs considered physicians' values and engagement as components of process and policy, rather than viewing them as exogenous factors affecting innovation adoption. These types of approaches enabled programs to accelerate acceptance of innovations within organizations.

Effects of a Community-Based Fall Management Program on Medicare Cost Savings.

INTRODUCTION: Fall-related injuries and health risks associated with reduced mobility or physical inactivity account for significant costs to the U.S. healthcare system. The widely disseminated lay-led A Matter of Balance (MOB) program aims to help older adults reduce their risk of falling and associated activity limitations. This study examined effects of MOB participation on health service utilization and costs for Medicare beneficiaries, as a part of a larger effort to understand the value of community-based prevention and wellness programs for Medicare. METHODS: A controlled retrospective cohort study was conducted in 2012-2013, using 2007-2011 MOB program data and 2006-2013 Medicare data. It investigated program effects on falls and fall-related fractures, and health service utilization and costs (standardized to 2012 dollars), of 6,136 Medicare beneficiaries enrolled in MOB from 2007 through 2011. A difference-in-differences analysis was employed to compare outcomes of MOB participants with matched controls. RESULTS: MOB participation was associated with total medical cost savings of $938 per person (95% CI=$379, $1,498) at 1 year. Savings per person amounted to $517 (95% CI=$265, $769) for unplanned hospitalizations; $81 for home health care (95% CI=$20, $141); and $234 (95% CI=$55, $413) for skilled nursing facility care. Changes in the incidence of falls or fall-related fractures were not detected, suggesting that cost savings accrue through other mechanisms. CONCLUSIONS: This study suggests that MOB and similar prevention programs have the potential to reduce Medicare costs. Further research accounting for program delivery costs would help inform the development of Medicare-covered preventive benefits.
