Emergency Department Length of Stay for Older Adults With Dementia.

STUDY OBJECTIVE: The emergency department (ED) poses unique challenges and risks to persons living with dementia. A longer ED length of stay is associated with the risk of death, delirium, and medication errors. We sought to determine whether ED length of stay differed by dementia status and trends in ED length of stay for persons living with dementia from 2014 to 2018 and whether persons living with dementia were at a higher risk for prolonged ED length of stay (defined as a length of stay > 90th percentile). METHODS: In this observational study, we used data from the Healthcare Cost and Utilization Project State Emergency Department Database from Massachusetts, Arkansas, Arizona, and Florida. We included ED visits resulting in discharge for adults aged ≥65 years from 2014 to 2018. We used inverse probability weighting to create comparable groups of visits on the basis of dementia status. We used generalized linear models to estimate the mean difference in ED length of stay on the basis of dementia status and logistic regression to determine the odds of prolonged ED length of stay. RESULTS: We included 1,039,497 ED visits (mean age: 83.5 years; 64% women; 78% White, 12% Hispanic). Compared with visits by persons without dementia, ED length of stay was 3.1 hours longer (95% confidence interval [CI] 3.0 to 3.3 hours) for persons living with dementia. Among the visits resulting in transfer, ED length of stay was on average 4.1 hours longer (95% CI 3.6 to 4.5 hours) for persons living with dementia. Visits by persons living with dementia were more likely to have a prolonged length of stay (risk difference 4.1%, 95% CI 3.9 to 4.4). CONCLUSION: ED visits were more than 3 hours longer for persons living with versus without dementia. Initiatives focused on optimizing ED care for persons living with dementia are needed.

Paid Care for People with Functional Impairment and Serious Illness: Results from the Health and Retirement Study.

BACKGROUND: Paid caregivers (e.g., home health aides) care for individuals living at home with functional impairment and serious illnesses (health conditions with high risk of mortality that impact function and quality of life). OBJECTIVE: To characterize those who receive paid care and identify factors associated with receipt of paid care in the context of serious illness and socioeconomic status. DESIGN: Retrospective cohort study. PARTICIPANTS: Community-dwelling participants ≥ 65 years enrolled in the Health and Retirement Study (HRS) between 1998 and 2018 with new-onset functional impairment (e.g., bathing, dressing) and linked fee-for-service Medicare claims (n = 2521). MAIN MEASURES: Dementia was identified using HRS responses and non-dementia serious illness (e.g., advanced cancer, end-stage renal disease) was identified using Medicare claims. Paid care support was identified using HRS survey report of paid help with functional tasks. KEY RESULTS: While about 27% of the sample received paid care, those with both dementia and non-dementia serious illnesses in addition to functional impairment received the most paid care (41.7% received ≥ 40 h of paid care per week). In multivariable models, those with Medicaid were more likely to receive any paid care (p < 0.001), but those in the highest income quartile received more hours of paid care (p = 0.05) when paid care was present. Those with non-dementia serious illness were more likely to receive any paid care (p < 0.001), but those with dementia received more hours of care (p < 0.001) when paid care was present. CONCLUSIONS: Paid caregivers play a significant role in meeting the care needs of those with functional impairment and serious illness and high paid care hours are common among those with dementia in particular. Future work should explore how paid caregivers can collaborate with families and healthcare teams to improve the health and well-being of the seriously ill throughout the income spectrum.

Use of the patient portal among older adults with diagnosed dementia and their care partners.

INTRODUCTION: Care partners are at the forefront of dementia care, yet little is known about patient portal use in the context of dementia diagnosis. METHODS: We conducted an observational cohort study of date/time-stamped patient portal use for a 5-year period (October 3, 2017-October 2, 2022) at an academic health system. The cohort consisted of 3170 patients ages 65+ with diagnosed dementia with 2+ visits within 24 months. Message authorship was determined by manual review of 970 threads involving 3065 messages for 279 patients. RESULTS: Most (71.20%) older adults with diagnosed dementia were registered portal users but far fewer (10.41%) had a registered care partner with shared access. Care partners authored most (612/970, 63.09%) message threads, overwhelmingly using patient identity credentials (271/279, 97.13%). DISCUSSION: The patient portal is used by persons with dementia and their care partners. Organizational efforts that facilitate shared access may benefit the support of persons with dementia and their care partners. Highlights Patient portal registration and use has been increasing among persons with diagnosed dementia. Two thirds of secure messages from portal accounts of patients with diagnosed dementia were identified as being authored by care partners, primarily using patient login credentials. Care partners who accessed the patient portal using their own identity credentials through shared access demonstrate similar levels of activity to patients without dementia. Organizational initiatives should recognize and support the needs of persons with dementia and their care partners by encouraging awareness, registration, and use of proper identity credentials, including shared, or proxy, portal access.

Catalyzing dementia care through the learning health system and consumer health information technology.

To advance care for persons with Alzheimer's disease and related dementias (ADRD), real-world health system effectiveness research must actively engage those affected to understand what works, for whom, in what setting, and for how long-an agenda central to learning health system (LHS) principles. This perspective discusses how emerging payment models, quality improvement initiatives, and population health strategies present opportunities to embed best practice principles of ADRD care within the LHS. We discuss how stakeholder engagement in an ADRD LHS when embedding, adapting, and refining prototypes can ensure that products are viable when implemented. Finally, we highlight the promise of consumer-oriented health information technologies in supporting persons living with ADRD and their care partners and delivering embedded ADRD interventions at scale. We aim to stimulate progress toward sustainable infrastructure paired with person- and family-facing innovations that catalyze broader transformation of ADRD care.

Factors Associated With Loss of Usual Source of Care Among Older Adults.

PURPOSE: Access to a usual source of care (USC) is associated with better preventive health and chronic disease treatment. Although most older adults have a USC, loss of USC, and factors associated with loss of USC, have not previously been examined. METHODS: We followed 7,609 participants of the National Health and Aging Trends Study annually for up to 6 years (2011-2016). Discrete time-to-event techniques and pooled logistic regression were used to identify demographic, clinical, and social factors associated with loss of USC. RESULTS: Ninety-five percent of older adults reported having a USC in 2011, of whom 5% subsequently did not. Odds of losing a USC were higher among older adults with unmet transportation needs (adjusted odds ratio [aOR] 1.67), who moved to a new residence (aOR 2.08), and who reported depressive symptoms (aOR 1.40). Odds of losing a USC were lower for those who had ≥4 chronic conditions (vs 0-1; aOR 0.42) and with supplemental (aOR 0.52) or Medicaid (aOR 0.67) insurance coverage. CONCLUSIONS: We identified factors associated with older adults' loss of a USC. Potentially modifiable factors, such as access to transportation and supplemental insurance, deserve further investigation to potentially assist older adults with continuous access to care.

Factors associated with imaging overuse in the emergency department: A systematic review.

BACKGROUND: Emergency departments (ED) are sites of prevalent imaging overuse; however, determinants that drive imaging in this setting are not well-characterized. We systematically reviewed the literature to summarize the determinants of imaging overuse in the ED. METHODS: We searched MEDLINE® and Embase® from January 1998 to March 2017. Studies were included if they were written in English, contained original data, pertained to a U.S. population, and identified a determinant associated with overuse of imaging in the ED. RESULTS: Twenty relevant studies were included. Fourteen evaluated computerized tomography (CT) scanning in patents presenting to a regional ED who were then transferred to a level 1 trauma center; incomplete transfer of data and poor image quality were the most frequently described reasons for repeat scanning. Unnecessary pre-transfer scanning or repeated scanning after transfer, in multiple studies, was highest among older patients, those with higher Injury Severity Scores (ISS) and those being transferred further. Six studies explored determinants of overused imaging in the ED in varied conditions, with overuse greater in older patients and those having more comorbid diseases. Defensive imaging reportedly influenced physician behavior. Less integration of services across the health system also predisposed to overuse of imaging. CONCLUSIONS: The literature is heterogeneous with surprisingly few studies of determinants of imaging in minor head injury or of spine imaging. Older patient age and higher ISS were the most consistently associated with ED imaging overuse. This review highlights the need for precise definitions of overuse of imaging in the ED.

First-Year Internal Medicine Residents' Reflections on Nonmedical Home Visits to High-Risk Patients.

PROBLEM: Patients who are high utilizers of care often experience health-related challenges that are not readily visible in an office setting but paramount for residents to learn. A nonmedical home visit performed at the beginning of residency training may help residents better understand social underpinnings related to their patient's health and place subsequent care within the context of the patient's life. INTERVENTION: First-year internal medicine residents completed a nonmedical home visit to an at-risk patient prior to seeing the patient in the office for his or her first medical visit. CONTEXT: We performed a thematic analysis of internal medicine interns' (n = 16) written narratives on their experience of getting to know a complex patient in his or her home prior to seeing the patient for a medical visit. Narratives were written by the residents immediately following the visit and then again at the end of the intern year, to assess for lasting impact of the intervention. Residents were from an urban academic residency program in Baltimore, Maryland, USA. OUTCOME: We identified four themes from the submitted narratives. Residents discussed the visit's impact on future practice, the effect of the community and support system on health, the impact on the depth of the relationship, and the visit as a source of professional fulfillment. Whereas the four themes were present at both time points, the narratives completed immediately following the visit focused more on the themes of impact of future practice and the effect of the community and support system on health. The influence of the home visit on the depth of the relationship was a more prevalent theme in the end-of-the-year narratives. LESSONS LEARNED: Although there is evidence to support the utility of learners completing medical home visits, this exploratory study shows that a nonmedical home visit can be rewarding and formative for early resident physicians. Future studies could examine the patient's perspective on the experience and whether a nonmedical home visit is a valuable tool in other patient populations.

The effect of dementia on patterns of healthcare use in older adults with diabetes.

BACKGROUND: For persons with diabetes, incidence of dementia has been associated with increased hospitalization; however, little is known about healthcare use preceding and following incident dementia. We describe healthcare utilization in the 3 years pre- and post-incident dementia among older adults with diabetes. METHODS: We used the National Health and Aging Trends Study (NHATS) linked to Medicare fee-for-service claims from 2011 to 2018. We included community-dwelling adults ≥65 years who had diabetes without dementia. We matched older adults with dementia (identified with validated NHATS algorithm) at the year of incident dementia to controls using coarsened exact matching. We examined annual outpatient visits, emergency department (ED) visits, hospitalization, and post-acute skilled nursing facility (SNF) use 3 years preceding and 3 years following dementia onset. RESULTS: We included 195 older adults with diabetes with incident dementia and 1107 controls. Groups had a similar age (81.6 vs 81.7 years) and were 56.4% female. Persons with dementia were more likely to be of minority racial and ethnic groups (26.7% vs 21.3% Black, non-Hispanic, 15.3% vs 6.7% other race or Hispanic). We observed a larger decrease in outpatient visits among persons with dementia, primarily due to decreasing specialty visits (mean outpatient visits: 3 years pre-dementia/matching 6.8 (SD 2.6) dementia vs 6.4 (SD 2.6) controls, p < 0.01 to 3 years post-dementia/matching 4.6 (SD 2.3) dementia vs 5.5 (SD 2.7) controls, p < 0.01). Hospitalization, ED visits, and post-acute SNF use were higher for persons with dementia and rose in both groups (e.g., ED visits 3 years pre-dementia/matching 3.9 (SD 5.4) dementia vs 2.2 (SD 4.8) controls, p < 0.001; 3 years post-dementia/matching 4.5 (SD 4.7) dementia vs 3.5 (SD 6.1) controls, p = 0.04). CONCLUSIONS: Older adults with diabetes with incident dementia have higher rates of acute and post-acute care use, but decreasing outpatient use over time, primarily due to a decrease in specialty visits.

The Annual Wellness Visit Health Risk Assessment: Potential of Patient Portal-Based Completion and Patient-Oriented Education and Support.

Background and Objectives: Patient portals are secure online platforms that allow patients to perform electronic health management tasks and engage in bidirectional information exchange with their care team. Some health systems administer Medicare Annual Wellness Visit (AWV) health risk assessments through the patient portal. Scalable opportunities from portal-based administration of risk assessments are not well understood. Our objective is 2-fold-to understand who receives vs misses an AWV and health risk assessment and explore who might be missed with portal-based administration. Research Design and Methods: This is an observational study of electronic medical record and patient portal data (10/03/2021-10/02/2022) for 12 756 primary care patients 66+ years from a large academic health system. Results: Two-thirds (n = 8420) of older primary care patients incurred an AWV; 81.0% of whom were active portal users. Older adults who were active portal users were more likely to incur AWV than those who were not, though portal use was high in both groups (81.0% with AWV vs 76.8% without; p < .001). Frequently affirmative health risk assessment categories included falls/balance concerns (44.2%), lack of a documented advanced directive (42.3%), sedentary behaviors (39.9%), and incontinence (35.1%). Mean number of portal messages over the 12-month observation period varied from 7.2 among older adults affirmative responses to concerns about safety at home to 13.8 for older adults who reported difficulty completing activities of daily living. Portal messaging varied more than 2-fold across affirmative health risk categories and were marginally higher with greater number affirmative (mean = 13.8 messages/year no risks; 19.6 messages/year 10+ risks). Discussion and Implications: Most older adults were active portal users-a group more likely to have incurred a billed AWV. Efforts to integrate AWV risk assessments in the patient portal may streamline administration and scalability for dissemination of tailored electronically mediated preventive care but must attend to equity issues.

Care partners and consumer health information technology: A framework to guide systems-level initiatives in support of digital health equity.

Introduction: Consumer-oriented health information technologies (CHIT) such as the patient portal have a growing role in care delivery redesign initiatives such as the Learning Health System. Care partners commonly navigate CHIT demands alongside persons with complex health and social needs, but their role is not well specified. Methods: We assemble evidence and concepts from the literature describing interpersonal communication, relational coordination theory, and systems-thinking to develop an integrative framework describing the care partner's role in applied CHIT innovations. Our framework describes pathways through which systematic engagement of the care partner affects longitudinal work processes and multi-level outcomes relevant to Learning Health Systems. Results: Our framework is grounded in relational coordination, an emerging theory for understanding the dynamics of coordinating work that emphasizes role-based relationships and communication, and the Systems Engineering Initiative for Patient Safety (SEIPS) model. Cross-cutting work systems geared toward explicit and purposeful support of the care partner role through CHIT may advance work processes by promoting frequent, timely, accurate, problem-solving communication, reinforced by shared goals, shared knowledge, and mutual respect between patients, care partners, and care team. We further contend that systematic engagement of the care partner in longitudinal work processes exerts beneficial effects on care delivery experiences and efficiencies at both individual and organizational levels. We discuss the utility of our framework through the lens of an illustrative case study involving patient portal-mediated pre-visit agenda setting. Conclusions: Our framework can be used to guide applied embedded CHIT interventions that support the care partner role and bring value to Learning Health Systems through advancing digital health equity, improving user experiences, and driving efficiencies through improved coordination within complex work systems.

Frequency and implications of coexistent manifestations of serious illness in older adults with dementia.

BACKGROUND: In older adults, serious illness comprises three manifestations: dementia, activity of daily living (ADL) impairment, and other advanced medical conditions (AMC; e.g., end-stage renal disease). Little is known about how dementia and other manifestations of serious illness co-occur. We aim to describe the prevalence of persons with dementia (PWD) who are living with additional manifestations of serious illness, and the implications on healthcare utilization, Medicare costs, caregiving hours and out-of-pocket expenses. METHODS: In this cross-sectional study, we use data from the 2016 Health and Retirement Study (HRS) linked to Medicare fee-for-service claims. We limited inclusion to adults >65 years. Dementia was determined using validated methodology that incorporates functional and cognitive test scores from HRS. We classified PWD as having dementia alone, dementia and an AMC (irrespective of ADL impairment) or dementia and ADL impairment (without an AMC). Healthcare utilization and Medicare costs were measured in claims, caregiving hours and out-of-pocket expenses were self-reported. RESULTS: Most PWD (67%) met criteria for another manifestation of serious illness (24% advanced medical condition, 44% ADL impairment). PWD and an AMC had the highest proportion of hospital use and the highest median total Medicare costs ($17,900 vs. $8962 dementia + ADL impairment vs. $4376 dementia alone). Mean total hours of caregiving per month were similar for PWD and an AMC and PWD and ADL impairment (142.9 and 141.9 h, respectively), while mean hours were much lower for PWD alone (47.7 h). Median out-of-pocket costs were highest for PWD and ADL impairment ($13,261) followed by PWD and an AMC ($10,837) and PWD alone ($7017). CONCLUSIONS: PWD commonly face another manifestation of serious illness. Dementia and ADL impairment was associated with the highest costs for PWD and families while dementia and an AMC was associated with the highest costs for Medicare.

Care manager, older adult, and caregiver perspectives on co-occurring care management among high-need older adults.

BACKGROUND: Care management programs are widely used to improve care coordination and management of chronic conditions for high-need older adults. With many care management programs targeting a small number of people, high-need older adults may receive services from more than one care management program (co-occurring care management), the implications of which are unknown. METHODS: We conducted semi-structured interviews with 37 care managers, 15 older adults, and 13 caregivers, who were recruited through an urban academic medical center and a large rural health system in Maryland. We analyzed interview transcripts using qualitative content analysis with the aim of understanding contributors to, implications of, and strategies to manage co-occurring care management among high-need older adults. RESULTS: Contributors to co-occurring care management included siloed programs due to program-specific financial incentives and inability to easily identify other involved care managers, and the complex needs of the enrolled older adult population, which motivated involvement of more than one program. Implications of co-occurring care management included older adults and caregivers feeling cared for and safe when they had multiple care management programs involved and reporting value in their relationships with care managers. Older adults were identified as having greater access to resources and improved care when care manager roles were aligned in a complementary way; however, misaligned roles posed the potential for confusion about care manager accountability for tasks and resulted in frustration and lack of follow-through. Strategies for managing co-occurring care management included alignment of care manager roles through communication and negotiation and older adults and caregivers identifying and relying on a single care manager with whom they had the strongest relationship. CONCLUSIONS: Initiatives that clarify strengthen the relationship between care managers and older adults, increase care manager visibility, and facilitate communication across care managers may help foster collaboration.

Effects of screening for geriatric conditions and advance care planning at the Medicare Annual Wellness Visit.

BACKGROUND: The Medicare Annual Wellness Visit (AWV) requires screening for geriatrics conditions and can include advance care planning (ACP). We examined (1) the prevalence of positive screens for falls, cognitive impairment, and activities of daily living (ADL) impairment, (2) referrals/orders generated potentially in response, and (3) the increase in ACP among those with two AWVs. METHODS: In this retrospective analysis, we used electronic medical record data from a Mid-Atlantic group ambulatory practice. We included adults age > 65 who had ≥1 AWV (n = 16,176) in years 2014-2017. Analyses on high-risk prescribing were limited to those (n = 13,537) with ≥3 months of follow up and ACP to those (n = 9097) with two AWVs. We used responses from the AWV health risk questionnaire to identify screening status for falls, cognitive and ADL impairment and whether an older adult had an ACP. For each screen we identified orders/referrals placed potentially in response (e.g., physical therapy for falls). High-risk medications were based on the 2019 Beers Criteria. RESULTS: Positive screening rates were 38% for falls, 23% for cognition, and 32% for ADL impairment. The adjusted odds of having an order placed potentially in response to the screening were 1.8 (95% CI 1.6-2.0) for falls, 1.4 (1.3-1.7) for cognition, 2.8 (2.4-3.3) for ADL impairment. The adjusted odds of a high-risk prescription in the 3 months after a positive screen were 2.1 (95% CI 1.8-2.5) for falls and 1.9 (95% CI 1.6-2.4) for cognition. Of those with two AWVs, 48% had an ACP at the first AWV. Among the remaining 52% with no ACP at the first AWV, the predicted probability of having an ACP at the second AWV was 0.22 (95% CI 0.18-0.25). CONCLUSION: Our results may indicate positive effects of screening for geriatric conditions at the AWV, and highlight opportunities to improve geriatrics care related to prescribing and ACP.

Fragmentation of care in the last year of life: Does dementia status matter?

BACKGROUND: Care at the end of life is commonly fragmented; however, little is known about commonly used measures of fragmentation of care in the last year of life (LYOL). We sought to understand differences in fragmentation of care by dementia status among seriously ill older adults in the LYOL. METHODS: We analyzed data from adults ≥65 years in the National Health and Aging Trends Study who died and had linked 2011-2017 Medicare fee-for-service claims for ≥12 months before death. We categorized older adults as having serious illness due to dementia (hereafter dementia), non-dementia serious illness or no serious illness. For outpatient fragmentation, we calculated the Bice-Boxerman continuity of care index (COC), which measures care concentration, and the known provider of care index (KPC), which measures the proportion of clinicians who were previously seen. For acute care fragmentation, we divided the number of hospitals and emergency departments visited by the total number of visits. We built separate multivariable quantile regression models for each measure of fragmentation. RESULTS: Of 1793 older adults, 42% had dementia, 53% non-dementia serious illness and 5% neither. Older adults with dementia had fewer hospitalizations than older adults with non-dementia serious illness but more than older adults without serious illness (mean 1.9 vs 2.3 vs 1, p = 0.002). In adjusted models, compared to older adults with non-dementia serious illness, those with dementia had significantly less fragmented care across all quantiles of COC (range 0.016-0.110) but a lower predicted 90th percentile of KPC, meaning more older adults with dementia had extremely fragmented care on the KPC measure. There was no significant difference in acute care fragmentation. CONCLUSIONS: In the LYOL, older adults with dementia have fewer healthcare encounters and less fragmentation of care by the COC index than older adults with non-dementia serious illness.

Prevalence of co-occurring serious illness diagnoses and association with health care utilization at the end of life.

INTRODUCTION: End-of-life care differs by serious illness diagnosis. Cancer and dementia are serious illnesses that have been associated with less intensive end-of-life health care use. It is not known how health care utilization varies in the presence of >1 serious illness. METHODS: We used the Rochester Epidemiology Project to identify persons living in a midwestern area who died on July 1, 2017-June 30, 2018 at age ≥65 years, and were seriously ill. We examined the number of emergency department (ED), hospital, and intensive care unit (ICU) stays in the last 6 months and the last 30 days of life. We used Poisson regression to determine the incidence rate ratio for ED, hospital, and ICU stay in the last 6 months and 30 days of life by number of serious illness diagnoses. For cancer and dementia, we examined the effect of an additional serious illness. RESULTS: We included a population of 1372 adults who were, on average, 84 years, 52% female, and 96% white. Approximately 41% had multiple serious illnesses. Compared to older adults with 1 serious illness diagnosis, rates of hospitalization, and ICU stay for adults with 2 or ≥3 serious illness diagnoses were at least 1.5 times higher in the last 6 months and the last 30 days of life. Rates of ED visits were significantly higher for older adults with 2 or ≥3 serious illness diagnoses in the last 6 months of life, but only higher for those with ≥3 versus 1 serious illness diagnosis in the last 30 days of life. For both cancer and dementia, rates of ED visits, hospitalization and ICU stay were lower for the condition alone than when an additional serious illness diagnosis was present. CONCLUSION: Having multiple serious illnesses increases the risk of health care utilization at the end of life.

National profile of the growing population of older adults who access community health centers.

BACKGROUND: Community health centers (CHCs) are federally funded safety-net clinics that provide care to low income and medically underserved persons. The proportion of CHC patients aged ≥65 doubled in the last ten years, yet little is known about this population. We aim to describe the demographic and clinical characteristics of the older adult CHC population. DESIGN: Cross sectional analysis. SETTING: The nationally representative 2014 Health Center Patient Survey. PARTICIPANTS: CHC patients ≥55 years. MEASURES: We used descriptive statistics to characterize older adults across demographic and clinical variables. To determine differences by age, we stratified into three groups (55-64, 65-74, 75+ years). We used t-tests and chi-squared to calculate p values and survey weights to make national estimates. RESULTS: We included 1875 older adults ≥55 years, representing over 4.2 million people. Older adults were mostly aged 55-64 (60%), female (51%), and white (60%). The majority (73%) had Medicare or Medicaid and 47% reported fair or poor health. Regardless of age, older adults had an average of three chronic conditions and 0.6 impairments in activities of daily living (ADL). Healthcare utilization was not significantly different across age groups with most taking ≥5 prescription medications (54%) and one in five reporting ≥2 emergency department visits or ≥1 hospitalization in the last year. CONCLUSIONS: Adults 55-64 who attend CHCs have similar disease burden as adults ≥65. As the population of older adults who access CHCs grow, our findings highlight the opportunity to enhance focus on key principles of geriatric medicine, such as measurement of functional impairment for those who are <65 while also addressing underlying health disparities.

"It's Tricky": Care Managers' Perspectives on Interacting with Primary Care Clinicians.

Care management programs that facilitate collaboration between care managers and primary care clinicians are more likely to be successful in improving chronic disease metrics than programs that do not facilitate such collaboration. The authors sought to understand care managers' perspectives on interacting with primary care clinicians. Semi-structured qualitative interviews were conducted with care managers (n = 29) from 3 health systems in and around a large, urban academic center. Interviews were audio recorded, transcribed verbatim, and iteratively analyzed using a grounded theory approach. Care managers worked for health plans (14%), outpatient specialty clinics (31%), hospitals and emergency departments (24%), and primary care offices (14%). Care managers identified the primary care clinician as leading patients' care and as essential to avoiding unnecessary utilization. Care managers described variability in and barriers to interacting with primary care clinicians. When possible, care managers use the electronic medical record to facilitate interaction rather than communicating directly (eg, phone call) with primary care clinicians. The role of the care manager varied across programs, contributing to primary care clinicians' poor understanding of what the care manager could provide. Consequently, primary care clinicians asked the care manager for help with tasks beyond his/her role. Care managers felt inferior to primary care clinicians, a potential result of the traditional medical hierarchy, which also hindered interactions. Although care managers view interactions with the primary care clinician as essential to the health of the patient, communication challenges, variability of the care manager's role, and medical hierarchy limit collaboration.
