Reductions in costly healthcare service utilization: findings from the Care Advocate Program

OBJECTIVES: To determine whether a telephone care-management intervention for high-risk Medicare health maintenance organization (HMO) health plan enrollees can reduce costly medical service utilization. DESIGN: Randomized, controlled trial measuring healthcare services utilization over three 12-month periods (pre-, during, and postintervention). SETTING: Two social service organizations partnered with a Medicare HMO and four contracted medical groups in southern California. PARTICIPANTS: Eight hundred twenty-three patients aged 65 and older; eligibility was determined using an algorithm to target older adults with high use of insured healthcare services. INTERVENTION: After assessment, members in the intervention group were offered mutually agreed upon referrals to home- and community-based services (HCBS), medical groups, or Medicare HMO health plan and followed monthly for 1 year. MEASUREMENTS: Insured medical service utilization was measured across three 12-month periods. Acceptance and utilization of Care Advocate (CA) referrals were measured during the 12-month intervention period. RESULTS: CA intervention members were significantly more likely than controls to use primary care physician services (odds ratio (OR)=2.05, P<.001), and number of hospital admissions (OR=0.43, P<.01) and hospital days (OR=0.39, P<.05) were significantly more stable for CA group members than for controls. CONCLUSION: Results suggest that a modest intervention linking older adults to HCBS may have important cost-saving implications for HMOs serving community-dwelling older adults with high healthcare service utilization. Future studies, using a national sample, should verify the role of telephone care management in reducing the use of costly medical services.     

Characteristics associated with home- and community-based service utilization for Medicare managed care consumers

PURPOSE: We identified the types of home- and community-based services (HCBS) that high-risk older adults in Medicare managed care used, and we examined participant characteristics associated with service use in six areas: overall service use, four specific categories of HCBS, and referrals to insured medical services. DESIGN AND METHODS: We used service data from the Care Advocate Demonstration Program, a telephone-based care-management intervention that linked chronically ill older adults to HCBS. Two hundred and twenty-four high-risk older adults who were enrolled in a southern California-based Medicare managed care plan received an assessment, service referrals, and 12 months of telephone follow-up by master's level social service professionals. We used logistic regression to estimate the odds of using the HCBS categories and medical services. RESULTS: Results indicated that characteristics associated with service use varied extensively, depending on the service. Age, gender, social support, living situation, education, specific functional impairments, heart conditions, and sensory impairments at baseline significantly predicted utilization in the six different service models. IMPLICATIONS: Policy implications include the importance of individualized care-management assessments that direct targeted referrals to appropriate services. Findings support the need for individualized care-management assessment and service planning, suggesting that a "one size fits all" approach to HCBS will not meet the varied needs of diverse consumers.     

Kaiser Permanente community partners project: improving geriatric care management practices

This article describes a geriatric care management project that is testing whether geriatric care management plus a brief purchase of service (POS) intervention will lower medical costs, improve satisfaction with care, increase care plan adherence, and improve perceived quality of life. Kaiser Permanente members aged 65 and older who were eligible for geriatric care management and consented to participate in the study were randomized to one of four study groups: information and referral via mail, telephone care management, geriatric care management, or geriatric care management with POS capability. The POS intervention provides up to $2,000 of designated, paid services including in-home supportive services, transportation, respite, or medical equipment within the first 6 months of care management enrollment. Approximately 1,400 senior members were referred to the geriatric care management program, and 451 were randomly assigned to one of the four study groups. Those enrolled in the geriatric care management program were significantly more likely to be ethnic minorities and have lower income than the general Kaiser Permanente senior enrollment. Barriers encountered in implementing the POS intervention included establishing contractual agreements between Kaiser Permanente and private and community agencies, locating adequate and sufficient community agencies to provided needed services, monitoring service contracts, and delaying use of the POS benefit.     

A novel emergency medical services-based program to identify and assist older adults in a rural community

Rural-dwelling older adults experience unique challenges related to accessing medical and social services. This article describes the development, implementation, and experience of a novel, community-based program to identify rural-dwelling older adults with unmet medical and social needs that leveraged the existing emergency medical services (EMS) system. The program specifically included geriatrics training for EMS providers; screening of older adult EMS patients for falls, depression, and medication management strategies by EMS providers; communication of EMS findings to community-based case managers; in-home evaluation by case managers; and referral to community resources for medical and social interventions. Measures used to evaluate the program included patient needs identified by EMS or the in-home assessment, referrals provided to patients, and patient satisfaction. EMS screened 1,231 of 1,444 visits to older patients (85%). Of those receiving specific screens, 45% had fall-related, 69% medication management-related, and 20% depression-related needs identified. One hundred and seventy-one eligible EMS patients who could be contacted accepted the in-home assessment. Of the 153 individuals completing the assessment, 91% had identified needs and received referrals or interventions. This project demonstrated that screening by EMS during emergency care for common geriatric syndromes and linkage to case managers is feasible in this rural community, although many will refuse the services. Further patient evaluations by case managers, with subsequent interventions by existing service providers as required, can facilitate the needed linkages between vulnerable rural-dwelling older adults and needed community-based social and medical services.     

Home- and community-based long-term care: lessons from Denmark

PURPOSE: Denmark is cited as a model in the development of home- and community-based systems for the frail elderly population. We examined the results of this natural experiment and considered implications for U.S. policy. DESIGN AND METHODS: We used international comparative policy analysis, including site visits and semistructured interviews with Danish leadership in conjunction with a review of published literature, reports, and administrative data from Denmark and the United States. RESULTS: After 12 years of implementing integrated systems for home- and community-based services in 275 municipalities, growth in Danish long-term care expenditures has leveled off; expenditures appear to be decreasing for the over-80 population and have dropped as a percentage of the gross domestic product. Access to and quality of long-term care services appear to remain generally satisfactory. During this period, comparable expenditures in the United States have increased, and deficits in access and quality persist. IMPLICATIONS: These findings should be of interest to state and federal policy makers considering strategies to reduce the rate of growth in Medicaid and Medicare expenditures for elders and to expand home- and community-based services.     

Medicare and Medicaid home health and Medicaid waiver services for dually eligible older adults: risk factors for use and correlates of expenditures

PURPOSE: The purpose of this work was to, among frail dually eligible older adults, determine risk factors for the likelihood of using Medicare home health and Medicaid home health services and to, among service users, determine correlates of Medicare home health, Medicaid home health, and Medicaid waiver service expenditures. DESIGN AND METHODS: Dually eligible individuals enrolled in Connecticut's Medicaid home- and community-based services (HCBS) waiver program for the aged (N = 5,232) were identified from a statewide database containing person-level linked data from Medicare claims, Medicaid claims, and uniform clinical assessment forms. Expenditures, based on claims data, were observed from the month following clinical assessment over the period August 1995 to December 1997. RESULTS: In multivariate models controlling for medical conditions and sociodemographic variables, similar functional disability measures were strongly associated with the probability of the use of, and expenditures for, Medicare home health and Medicaid home health services; severe cognitive impairment was strongly associated with greater Medicaid waiver service expenditures. IMPLICATIONS: Given the similarity of factors associated with Medicare and Medicaid home health service use and expenditures, greater integration of Medicare and Medicaid financing, reimbursement, and delivery strategies for home health services may be feasible and warranted for dually eligible older adults enrolled in state Medicaid HCBS waiver programs.     

Social networks and cognitive function in older adults receiving home- and community-based aged care

ObjectivesSocial engagement has been linked to preserved cognitive functioning in later life. Yet, little is known about the specific network factors that best predict cognitive function in older adults. This study aimed to (i) characterize the quality and quantity of interpersonal relationships and (ii) explore the relationship between social network types and cognitive function in older adults receiving home- and community-based aged care services.MethodsParticipants (n = 175) receiving aged care services participated in a structured interview regarding their cognitive function (Telephone Interview for Cognitive Status-Modified), social networks (Lubben Social Network Scale-12) and quality of life (European Quality of Life Scale). Socio-demographic and aged care service use factors were obtained from provider electronic management systems. Multiple regression analyses were conducted to examine the relationships between the size and composition of clients’ social networks, aged care service use and cognition.ResultsThe sample had a median age of 81 years (range 61-96) and most were women (65.8%). Over a third (37.6%) had cognitive impairment and reported moderately high social networks. Males had higher social networks, were receiving fewer hours but more types of services, and had significantly better cognitive performance. Age, network size and composition were not associated with cognitive performance.DiscussionMore extensive social networks were associated with maintenance of cognitive health for older adults in community aged care. Whether this is causal or a marker of better cognitive health requires a longitudinal approach, and ideally should be tested with interventions at community levels.     

Differences in HIV risk behavior of injection drug users in New York City by health care setting

The purpose of this study is to examine the HIV risk behaviors and demographic characteristics of injection drug users (IDUs) by type of health care setting, which can inform development of tailored structural interventions to increase access to HIV prevention and medical treatment services. IDU syringe customers were recruited from pharmacies as part of the “Pharmacist As Resources Making Links to Community Services” (PHARM-Link) study, a randomized community-based intervention in New York City (NYC) aimed at connecting IDUs to HIV prevention, medical, and social services. An ACASI survey ascertained demographics, risk behavior, health-care utilization, and location where health care services were received in the past year. Data were analyzed using logistic regression. Of 602 participants, 34% reported receiving health care at a community clinic, 46% a private medical office, 15% a mobile medical unit, and 59% an emergency room (ER). After adjustment, participants who attended a community clinic were significantly more likely to have health insurance, report syringe sharing, and be HIV positive. Whites, nondaily injectors, insured, and higher income IDUs were more likely to attend a private medical office. Participants who recently used a case manager and had multiple sexual partners were more likely to use a mobile medical unit. ER attendees were more likely to be homeless and report recent drug treatment use. These findings show that IDU demographics and risk behaviors differ by health care setting, suggesting that risk reduction interventions should be tailored to health care settings. Specifically, these data suggest that community clinics and mobile medical units serve high-risk IDUs, highlighting the need for more research to develop and test innovative prevention and care programs within these settings.     

Home-and community-based alternatives to nursing homes: services and costs to maintain nursing home eligible individuals at home

This study analyzes home- and community-based services (HCBS) use patterns and determines the costs of purchasing in-home services comparable to those offered by SCAN(R), a Social HMO. METHODS. Administrative data on 8,229 nursing home certifiable members were used to profile use patterns; a telephone survey gathered data on the market value of these services. RESULTS. Frail Social HMO members used a variety of HCBS to remain independent at home. These individuals would spend an average of $4,900 out of pocket per year to purchase equivalent HCBS, if they were not enrolled in the Social HMO. DISCUSSION. Findings suggest that the costs of maintaining a Social HMO member at home are modest and affordable, yet offer a substantial benefit, particularly to low- and moderate-income older people. With the aging of the population, an integrated medical and social program, such as the Social HMO, offers a viable policy solution.     

Profile of people referred to an emergency department from residential care

Background : Elderly people in residential care are among the most infirm in society and are at high risk of developing acute medical problems. There are no Australian data on the use of acute hospital emergency services by this group.
Aim : To determine patterns of use of a major public hospital's Emergency Department (ED) by elderly people living in residential care, their presenting problems and the outcome of attendance.
Methods : Prospective study of 300 consecutive referrals to a teaching hospital's ED involving people aged over 65 years and living in residential care in southern Adelaide, South Australia. Case records were examined and residential care staff were interviewed by telephone when information required clarification. This occurred in 25% of referrals.
Results : The 300 referrals were seen over a three month period and accounted for 2.43% of the 12,371 ED attendances during this period. During this time, at least 4.9% of people in residential care in the region were referred to the ED. The referrals involved 239 residents, 196 (82%) who were referred once only, 32 (13%) twice and 11 (5%) three or more times. Residents had a mean age of 84 years and 70% were female. A broad range of acute medical problems precipitated referral and 61% of people referred were immediately hospitalised. There was no general practitioner (GP) involvement in the management of the presenting illness in 58% of all referrals and in 45% of those where symptoms had been present for over three days.
Conclusions : People living in residential care are frequently referred to an ED service, often bypassing their GP in the process. They present with a wide range of acute medical problems for which most are hospitalised. Strategies that anticipate, prevent and manage health breakdown in residential care and so minimise the need for ED referral should be trialed.     

The effects of a variant of the program for all-inclusive care of the elderly on hospital utilization and outcomes

OBJECTIVES: To compare the effects of the Wisconsin Partnership Program (WPP) on hospital, emergency department (ED), and nursing home utilization with those of traditional care. DESIGN: Quasi-experimental longitudinal cohort design. SETTING: Selected counties in Wisconsin. PARTICIPANTS: WPP elderly enrollees and two matched control groups consisting of frail older people enrolled in fee-for-service insurance plans, Medicare, and Medicaid and receiving home- and community-based waiver services, one from the same geographic area as the WPP and another from a location in the state where the WPP was not offered. MEASUREMENTS: Data came from administrative records. Regression and survival analyses were adjusted for case-mix variables. RESULTS: No significant differences in hospital utilization, ED visits, preventable hospitalizations, risk of entry into nursing homes, or mortality were found. WPP enrollees had more contact with care providers than did controls. CONCLUSION: WPP did not dramatically alter the pattern of care. Part of the weak effect may be attributable to the small numbers of WPP cases per participating physician.     

Health outcomes and medicaid costs for frail older individuals: a case study of a MCO versus fee-for-service care

Older individuals receiving both Medicare and Medicaid benefits are known to have a disproportionate burden of illness and high medical care costs. Elder Health, Inc., a private, for-profit managed care organization operating in Maryland under capitation rates from both Medicare and Medicaid, has tailored a medical practice to these individuals, with the stated objective of providing integrated care. This study compared 200 Elder Health patients with a closely matched group of dually eligible older individuals receiving care in fee-for-service practices. There was a baseline in-home structured interview with the patient, followed 1 year later with a telephone interview. Other data sources were Medicaid claims data and Elder Health's utilization records. The outcomes of interest were the patients' health and functional status, their satisfaction with care, rates of use of medical services, and costs to Medicaid.Elder Health patients had similar general health status, better functional status, and greater satisfaction with access to care but less satisfaction with information giving than the fee-for-service group. They received more primary care and preventive services and had less than half the number of hospital days. Costs to Medicaid were nearly identical. Institutional and community-based long-term care costs were not included in the analysis.As pressures mount for the Health Care Financing Administration to expand its prepaid contracts with private health plans and the need for integrated programs increase, quantitative assessment of innovative delivery models such as Elder Health, Inc. will be essential to ensure that patients' and the publics' interests are well served.     

Policy choices for Medicaid and Medicare waivers

This article reviews the authority and processes for issuing Medicare and Medicaid waivers, highlights waiver-based differences in states' home- and community-based (HCB) service systems, and critiques emerging efforts to capitate, integrate, and privatize the long-term care system. Potential pitfalls relate to payment rates, risk, service substitution, accountability, and drains on HCB infrastructure. Before merging HCB services into larger prepaid systems, policy makers are advised to examine implementation challenges, resist ad hoc fixes, clarify HCB entitlements, and strengthen current infrastructure.     

A screening system for Michigan's home- and community-based long-term care programs

PURPOSE: To develop a screening system for Michigan's MI Choice publicly funded home- and community-based services programs, to aid in identifying both individuals eligible for services and their most appropriate level of care (LOC). DESIGN AND METHODS: Identify assessment items from the Minimum Data Set for Home Care (MDS-HC) assessment instrument that are predictive of five LOCs determined by expert care managers: nursing home, home care, intermittent personal care, homemaker, and information and referral (without services). RESULTS: The algorithm based on approximately 30 client characteristics agrees with expert opinions substantially better (kappa =.62) than systems based on activities of daily living and instrumental activities of daily living only (kappa <.40). IMPLICATIONS: The screening algorithm can be used both over the telephone to identify clients who will not be fully assessed (as they are unlikely to receive services) and in person to recommend the appropriate LOC.     

Referral gridlock

BACKGROUND: Patients' barriers to mental health services are well documented and include social stigma, lack of adequate insurance coverage, and underdiagnosis by primary care physicians. Little is known, however, about challenges primary care physicians face arranging mental health referrals and hospitalizations. OBJECTIVE: To examine how practice setting and environment influence primary care physicians' ability to refer patients for medically necessary mental health services. DESIGN: Cross-sectional analysis using nationally representative survey data from the 1998 to 1999 Community Tracking Study physician survey. The overall survey response rate was 61%. PARTICIPANTS: A 1998 to 1999 telephone survey of 6586 primary care physicians. MEASUREMENTS: Primary care physicians' report of whether they could obtain medically necessary referrals to high-quality mental health specialists or psychiatric admissions. RESULTS: Overall, 54% of primary care physicians reported problems obtaining psychiatric hospital admissions, and 54% reported problems arranging outpatient mental health referrals. Primary care physicians practicing in staff and group model HMOs were much less apt to report difficulties than physicians in solo and small-group practices (P <.001). Reports of inadequate time with patients (P <.001) and smaller numbers of psychiatrists in a market area (P <.01) also were associated with problems obtaining mental health referrals. Pediatricians were more apt to report problems than general internists (P <.001). CONCLUSIONS: Primary care physicians face greater hurdles obtaining mental health services than other medical services. Primary care is an important entry point for mental health services, yet inadequate referral systems between medical and mental health services may be hampering access.     

Cooperative dementia care clinics: A new model for managing cognitively impaired patients

Cooperative health care clinics (CHCCs), or shared medical appointments, are a healthcare innovation that can improve access and expand physicians' capacity to manage common geriatric conditions. This report describes a pilot program and working model for extending CHCCs to patients with dementia. Three cooperative dementia care clinics (CDCCs) met monthly for up to 1 year, drawing participants from a dementia clinic roster of patients and caregivers who had required continued specialty care for at least 3 months. Twenty-six of 33 eligible patient-caregiver dyads expressed interest, and 21 enrolled; five whose clinical status changed during the year withdrew and were replaced with new members. Brief introductory socialization, individualized clinical management, and an educational focus selected from problems of patients and caregivers were common to all sessions. Most participants required several types of clinical intervention and educational support. One group ended after reaching a natural termination point, and two others are ongoing at the request of participants. CDCCs can be a viable approach to increasing dementia care capacity in health systems. Formal service intervention trials to evaluate the generalizability and comparative effectiveness and economic viability of this model versus usual care are an appropriate next step.     

Two models of managed long-term care: comparing PACE with a Medicaid-only plan

PURPOSE: In this study an attempt is made to understand how a Medicaid-only managed long-term-care (MMLTC) plan for elders differs from the Program of All-Inclusive Care for the Elderly (PACE), a fully integrated model, in terms of structure, operations, patient population, and service utilization. DESIGN AND METHODS: With the use of information from the Outcome and Assessment Information Set and administrative data from a MMLTC plan in New York City, enrollees were compared at the start of care and their first-year service utilization with PACE, using the PACE national data set. RESULTS: The plans differ in the range of services covered and in the larger number of members served by the MMLTC plan. The served populations differ in their sociodemographic profiles and have levels of functional need that are high, but they also differ in their relative severity of dependency in activities of daily living and instrumental activities of daily living. During the first year of enrollment, the utilization of traditional home- and community-based services was higher in PACE than in the MMLTC plan, although MMLTC plan members received much more care in the home. Total hospital utilization was lower in PACE, but nursing home utilization was higher. IMPLICATIONS: MMLTC is a feasible option for serving a population whose level of impairment is similar to that of PACE. Whereas PACE's reliance on adult day centers is seemingly associated with a stronger medical focus and lower hospital use, the MMLTC plan's emphasis on home-based personal care seems to be linked with lower nursing home use.     

The effect of geriatric evaluation and management on Medicare reimbursement in a large public hospital: a randomized clinical trial.

OBJECTIVE: To study the effect of a geriatric evaluation and management program on health care charges and Medicare reimbursement. DESIGN: Prospective randomized controlled trial during a 1-year study period. SETTING: Large medical school-affiliated public hospital in an urban community. SUBJECTS: Patients at least 70 years old admitted to the medicine service were screened and randomized into two groups of 100 patients each. INTERVENTION: Patients randomized to the experimental group underwent initial comprehensive geriatric evaluation and once discharged from the hospital were enrolled in a geriatric care management and treatment program. The control group received usual care only. The major intervention of this study was in outpatient long-term care. MAIN OUTCOME MEASURE: Total charges for services billed to Medicare Part A and Part B and total Medicare reimbursement. The Medicare charge and reimbursement data were obtained by use of the Medicare Automated Data Retrieval System, a linked Medicare Part A and Part B utilization file. RESULTS: Total charges and reimbursement were greater for the control group but not significantly so. Subset analysis revealed significantly greater inpatient charges (P < 0.03) and Medicare reimbursement (P < 0.005) for the control patients and a greater likelihood of utilization of home health care services in the experimental group (P < 0.01). CONCLUSION: A geriatric evaluation and management program appeared to shift utilization and Medicare expenditures from inpatient services to home health care services. There was no evidence that the experimental program resulted in increased expenditures for Medicare. In selected populations, geriatric evaluation and management programs may contribute to cost containment.     

A randomized trial of a screening, case finding, and referral system for older veterans in primary care

OBJECTIVES: To test whether a system of screening, assessment, referral, and follow-up provided within primary care for high-risk older outpatients improves recognition of geriatric conditions and healthcare outcomes. DESIGN: Controlled clinical trial with 3-year follow-up; intervention versus control group allocation based on practice group assignment. SETTING: Department of Veterans Affairs (VA) ambulatory care center. PARTICIPANTS: Seven hundred ninety-two community-dwelling patients aged 65 and older identified by postal screening survey. INTERVENTION: The intervention combined a structured telephone geriatric assessment by a physician assistant, individualized referrals and recommendations, selected referral to outpatient geriatric assessment, and ongoing telephone case management. MEASUREMENTS: Main outcomes were VA medical record evidence of recognition and evaluation of target geriatric conditions (depression, cognitive impairment, urinary incontinence, falls, functional impairment), functional status (Functional Status Questionnaire, FSQ), and hospitalization (VA databases and self-reported non-VA usage). RESULTS: Intervention participants were more likely to have target conditions recognized, evaluated, and referred to specialized services within 12 months of enrollment, although there were no significant differences in FSQ scores or acute hospitalization between intervention and control groups at 1, 2, or 3 years follow-up. Subgroup analyses suggested improvements in depression symptoms and functional impairment at 1-year follow-up in intervention participants with these problems at baseline, but these findings were not evident at later follow-up. CONCLUSION: The intervention increased recognition and evaluation of target geriatric conditions but did not improve functional status or decrease hospitalization. Innovative screening methods can identify older people in need of geriatric services, but achieving measurable improvement in functional status or hospitalization rates will likely require a more-intensive intervention than a program involving primarily unsolicited referrals and short-term consultations.     

The association of ambulatory care with breast cancer stage at diagnosis among medicare beneficiaries

OBJECTIVE: Although nearly all elderly Americans are insured through Medicare, there is substantial variation in their use of services, which may influence detection of serious illnesses. We examined outpatient care in the 2 years before breast cancer diagnosis to identify women at high risk for limited care and assess the relationship of the physicians seen and number of visits with stage at diagnosis. DESIGN: Retrospective cohort study using cancer registry and Medicare claims data. PATIENTS: Population-based sample of 11,291 women aged > or =67 diagnosed with breast cancer during 1995 to 1996. MEASUREMENTS AND MAIN RESULTS: Ten percent of women had no visits or saw only physicians other than primary care physicians or medical specialists in the 2 years before diagnosis. Such women were more often unmarried, living in urban areas or areas with low median incomes (all P> or =.01). Overall, 11.2% were diagnosed with advanced (stage III/IV) cancer. The adjusted rate was highest among women with no visits (36.2%) or with visits to physicians other than primary care physicians or medical specialists (15.3%) compared to women with visits to either a primary care physician (8.6%) or medical specialist (9.4%) or both (7.8%) (P<.001). The rate of advanced cancer also decreased with increasing number of visits (P<.001). CONCLUSIONS: Even within this insured population, many elderly women had limited or no outpatient care in the 2 years before breast cancer diagnosis, and these women had a markedly increased risk of advanced-stage diagnosis. These women, many of whom were unmarried and living in poor and urban areas, may benefit from targeted outreach or coverage for preventive care visits.
