Residential care supply and cognitive and physical problem case mix in nursing homes.

OBJECTIVES: A rapid evolution has occurred in state policy and industry practices relative to assisted living and expanded use of residential care facilities for people with physical and cognitive frailty, yet relatively little is known about the interrelationship between this housing supply and nursing-home case mix. METHODS: The association between residential care supply and the proportion of cognitively and physically impaired nursing facility residents was examined in more than 1,500 facilities in five states. RESULTS: The proportion of nursing-home cases with only physical and cognitive impairment likely to be affected by emerging long-term care policy appears to be well under 10%. This effect is more persistent among admissions than continuing cases. DISCUSSION: The findings raise caution about the optimistic assumptions of the interplay between residential care/assisted living policy and nursing-home use.

Implementing the second generation social health maintenance organization.

BACKGROUND: In 1996 the Health Care Financing Administration implemented a second generation of the Social HMO demonstration. This model retained the chronic care benefits of the original Social HMOs while attempting to develop a geriatric service model integrated into primary care and a screening and assessment process focused directly on healthcare risk factors. Other refinements included risk-adjusted capitation payment, broadened eligibility for expanded care benefits, low co-payments for these benefits, and no caps on the expanded care benefits expenditures. OBJECTIVES: The geriatric approach is designed to facilitate integration among providers and levels of care. This includes timely application of primary care monitoring and treatment to reduce illness and disability as well as a geriatric education and consultation program to provide specialty support for complex cases. Care management is designed for those requiring home-based care, those discharged from hospitals or nursing homes, and those having difficulty with treatment regimens. DESIGN: A case study of the Social HMO implementation through the Fall of 1999. SETTING: Health Plan of Nevada (HPN), with locations in Las Vegas, Reno, and surrounding areas. PARTICIPANTS: More than 25,000 Medicare beneficiaries participated during the study period. MEASUREMENTS: Administrative reports, charts, and interviews with administrators and clinicians. RESULTS: Within 12 months of operation under this authority, HPN succeeded in putting in place most of the components of the planned geriatric approach: a screening program to identify patients "at risk" for high service costs and disability and timely application of primary care treatment to reduce illness and disability. Geriatric education and a consultation program for complex cases were available, but full implementation was delayed until the plan was able to hire a full time geriatrician. CONCLUSIONS: Health Plan of Nevada's Social HMO program reflects current perspectives on how to integrate chronic care into an HMO. The accomplishments affirm that the provision of risk-adjusted reimbursement, along with the 5 % supplement to the normal Medicare capitation payment, are sufficient incentives for a health plan to restructure itself so that it places a priority on retaining and serving populations at risk for high expenditures.

Residential care supply, nursing home licensing, and case mix in four states.

Simulation analyses quantify admission and continuing physical and cognitive impairment patient case-mix changes under two scenarios: with increases in residential care supply and with all nursing homes licensed only as skilled care facilities. Findings raise caution about the assumed interplay between residential care supply and nursing home use. The proportion of nursing home patients with only physical and cognitive impairment likely to be affected by current and emerging long-term care (LTC) policy was well under 25 percent of the nursing home population in each of the four study States. States varied in LTC supply and utilization controls.

Misclassification and selection bias when identifying Alzheimer's disease solely from Medicare claims records.

BACKGROUND: Medicare claims as the basis for health condition adjustments is becoming a method of choice in capitation reimbursement. A recent study has found that claims-based beneficiary classification for Alzheimer's disease produces lower prevalence estimates and higher average costs than previous healthcare cost studies in this population. These sets of studies differ in data sources, period length, and in their specification of dementia. OBJECTIVES: Participants in the Medicare Alzheimer's Disease Demonstration (MADDE) provide a sample of persons known to have some form of dementia. This group is used to test the adequacy of claims data for identifying eligible cases and any bias in expenditure differences between those flagged or not flagged by a claim in a given period. DESIGN: A prospective cohort design using up to 36 months of claims data. SETTING: The demonstration enrolled 4166 participants in treatment, and 3942 in a control group in eight communities across the US. Cases were combined in this analysis. PARTICIPANTS: Persons with available Medicare Part A & B claims data: those receiving care under fee for service reimbursement were used in the analysis. A total of 5379 MADDE cases received fee for service care during 1991 and 1992, the period of primary interest in the analysis. MEASUREMENT: Client health and functional status interviews and Medicare Part A & B claims. RESULTS: Less than 20% of MADDE participants were classified with Dementia of the Alzheimer type (DAT) from a single year of claims although 68% had a DAT diagnosis from a referring physician. Annualized expenditures were 1.7 times higher among those with DAT from claims compared with those known otherwise to have dementia but who had not been identified with this condition from Medicare claims. CONCLUSION: Underclassification of dementia from claims records can be partially remedied by increasing the period during which claims are compiled, but additional diagnostic sources will likely be needed to increase prevalence counts closer to 100% of true cases. Risk adjustment based on a single year of reported claims expenditures may overpay providers, at least in the short term, because payment incentives will likely increase prevalence reporting.

Effects of the Medicare Alzheimer's Disease Demonstration on the use of community-based services.

STUDY QUESTION: Did the Medicare Alzheimer's Disease Demonstration with its case management and community service waivers affect the use of community-based long-term care services among people with dementia and their primary caregivers? DATA SOURCES: Baseline and periodic caregiver interviews. Measures include client and caregiver attributes and self-reported service use. STUDY DESIGN: The demonstration randomly assigned voluntary applicants into treatment and control groups. Treatment group cases were eligible for case management and for up to $699 per month in community care benefits. The actual monthly entitlement varied among the eight demonstration communities due to regional cost and inflation adjustments over time. Analyses are for the year after enrollment. DATA COLLECTION: Analyses are of cases surviving six months or more in the community after enrollment (n = 5,209). Cases received baseline and semi-annual assessments. PRINCIPAL FINDINGS: The intervention of case management and community service reimbursement had a strong, consistent, and positive effect on the likelihood of using home care (including homemaker/chore services, personal care services, companion services) and adult day care. Treatment group clients were at least twice as likely as control group clients to be using any of the four community-based services. A similar, but less pervasive effect was achieved with caregiver training and support group participation. Reimbursement provided by the demonstration's Medicare waiver was generally not sufficient to exceed the level of control group service acquired through private payment. CONCLUSIONS: Reimbursement levels within the demonstration may have enabled more individuals to purchase some services, but they were not sufficient to increase the average level of use over those in the control group. No consistent differences between demonstration models were found in service use likelihood or average use among users.

Effects of the Medicare Alzheimer's Disease Demonstration on caregiver burden and depression.

STUDY QUESTION: Does improved access to community-based care reduce perceived burden and reported levels of depression among primary caregivers of people with dementia? DATA SOURCES: Baseline and periodic caregiver interviews with participants in the Medicare Alzheimer's Disease Demonstration. Client and caregiver attributes and caregiver outcomes such as depression and burden scores were among the measures. STUDY DESIGN: Applicants to the demonstration (all voluntary) were randomly assigned into treatment and control groups. Treatment group cases were eligible for case management and for up to $699 per month in community care benefits. (The actual monthly entitlement varied among the eight demonstration communities due to regional cost differences and inflation adjustments over the four-year demonstration period.) DATA COLLECTION: A total of 5,307 eligible individuals received a baseline assessment at the time of application to the demonstration and at least one semi-annual reassessment. Clients and their caregivers were periodically reassessed producing a total of 20,707 observations. PRINCIPAL FINDINGS: Persons in the treatment group had a high exposure to case management and a greater likelihood of community service use relative to those in the control group. Treatment group membership was associated with statistically significant, but very small reductions in caregiver burden (in four of eight sites) and depression (three of eight sites) over a 36-month tracking period. These findings are not sustained with all cases combined, or among a higher-resource demonstration model considered separately. CONCLUSIONS: Both the fact that these programmatic differences did not translate into substantial treatment group reductions in caregiver burden or depression, and the consistency of these findings with those of prior case management evaluations suggest the need to reformulate this programmatic intervention into areas not previously tested: 24-hour care, crisis intervention, coordination with primary care, or chronic disease management.

Effects of the Medicare Alzheimer's Disease Demonstration on nursing home entry.

STUDY QUESTION: Did the Medicare Alzheimer's Disease Demonstration, with its goal of improving caregiver outcomes through case management and subsidized community services, affect the nursing home entry rate of treatments with dementia compared to controls? DATA SOURCES: Interviews conducted at baseline and six months thereafter. Measures include date of nursing home entry, client and caregiver health, and income. STUDY DESIGN: The demonstration randomly assigned voluntary applicants into treatment and control groups. Treatment group cases were eligible for case management and for an 80 percent discount on community care benefits, up to about $600 per month. DATA COLLECTION: All cases received baseline and semi-annual assessment interviews for up to three years after enrollment. Analyses are among cases that remained in the demonstration for more than 30 days after enrollment (n = 8,095). PRINCIPAL FINDINGS: The intervention of case management and subsidized community service had no effect on nursing home entry rates for treatments overall, compared to those of controls, and few effects on treatment subgroups, with the exception of one site where it may have increased nursing home entry rates. CONCLUSIONS: Providing case management and subsidized community services with the goal of improving caregiver outcomes may have little effect on nursing home entry rates for people with dementia.

Effects of the Medicare Alzheimer's disease demonstration on Medicare expenditures.

Applicants were randomized either into a group with a limited Medicare community care service benefit and case management or into a control group receiving their regular medical care. Analyses assess whether or not community care management affected health care use. A tendency toward reduced expenditures was observed for the treatment group, combining all demonstration sites, and when observing each separately. These differences were or approached statistical significance in two sites for Medicare Part A and Parts A and B expenditures averaged over 3 years. Expenditure reductions approached budget neutrality with program costs in two sites.

Case management, client risk factors and service use.

Six "pure" types of case-manager activity are identified using chart data from 922 cases in the Medicare Alzheimer's Disease Demonstration. The association between case-manager actions and client characteristics, and between case-manager activities and service use outcomes is used to test predictive validity. Case-manager activity is generally more associated with caregiver than client characteristics. Monitoring and service management was protective against nursing home placement. A clinical nursing emphasis was protective against hospitalization. Understanding how case management is differentiated may improve staffing, treatment protocol, and client service outcomes.

Caregiver supports: outcomes from the Medicare Alzheimer's disease demonstration.

A randomized 3-year study assessed the effect of expanded community-based services and case management on 5,254 caregivers of dementia clients. A tested policy concern was whether the financing of formal care would result in a reduction of informal assistance. Unmet needs task assistance for the demonstration's treatment group caregivers decreased by 30 percent within 6 months and by about 20 percent over 36 months relative to controls. While treatment group members used slightly more formal care over time, there were no differences between treatment and control groups in primary caregiver hours after 36 months, or in the number of tasks in which primary or secondary caregivers provided assistance.

Prior and current costs in capitated health plans: the effects of health status at enrollment.

We compared the prior and current costs of persons age 65 and older enrolling in a Social/Health Maintenance Organization in each of four sites with samples of persons using standard Medicare benefits in each site. Analyses were adjusted for individual health differences using case mix scores. Costs were examined in the year before S/HMO enrollment or prior to the sampling of a person using regular Medicare services as well as costs during the study. Costs during the study are analyzed using a two-stage procedure where first the propensity to enroll in a S/HMO is modeled and then costs derived from either Medicare sources or shadow prices assigned to service units provided in a S/HMO are modeled. The costs for case mix groups with different health and functional characteristics varied significantly. Cost differences between case mix classes differed between the S/HMO and FFS populations.

Health plan satisfaction and risk of disenrollment among social/HMO and fee-for-service recipients.

Health plan satisfaction among the elderly is affected by multiple individual and locational factors. We used a general behavioral framework of predisposing, enabling, and service use factors to produce adjusted satisfaction scores. These then were included in a logistic analysis to determine the effect of satisfaction on continued membership in social health maintenance organizations (S/HMOs) or continued participation in fee-for-service care. S/HMO members, after one year in the plan, generally reported satisfaction scores comparable to Medicare beneficiaries in fee-for-service care. Satisfaction with perceived physician quality and interpersonal relationships with the providers reduced the risk of disenrollment. Functional impairment reduced the likelihood of disenrollment, but this effect varied by community. Being impaired was protective in communities with established HMOs. In markets where HMOs were emerging or where intensive HMO competition was beginning, disability increased the likelihood of changing current coverage. S/HMO membership, after adjusting for the market area's general disenrollment propensities, had varying effects. Being a newly formed plan was not a consistent predictor of higher disenrollment rates.

Case mix controlled service use and expenditures in the social/health maintenance organization demonstration.

BACKGROUND: The social health maintenance organization (S/HMO) demonstration was implemented, in part, to determine if the presumed integration of acute and chronic care in these plans could produce sufficient savings to allow plans to offer expanded and chronic care benefits without increased cost to the Medicare program. METHODS: S/HMO members and a sample of fee-for-service (FFS) recipients were tracked over three years to assess their utilization experience. Analyses controlled for case mix, using Grade of Membership procedures. RESULTS: In 1987, the last year of risk sharing, S/HMOs reported higher total expenditures than FFS in each health status class. For the "healthy," differences were largest for physician care. In other classes, differences in nonskilled nursing or home care use were noted. In 1988, the first year of full risk, Seniors Plus had equivalent or lower expenditures relative to FFS for all classes. Elderplan had lower expenditures in four of six classes and provided more service to the "frail" and the "acutely ill." SHP had higher expenditures in all classes because of higher hospital and nursing home expenditures. Medicare Plus II had higher expenditures in all classes, for physician, nonskilled nursing home, and home care expenditures. CONCLUSIONS: Overall plan losses and higher expenditures among a number of case mix groups suggest a need for refinement of S/HMO operations--especially in case management relationships to medical care and in the selection of "high risk" cases.

Evaluating long-term care demonstrations in real time with study design and plan performance interactions.

The evaluation of long-term care demonstrations has to deal with complex organizational entities, with large, heterogeneous client populations that, during the course of study, may have to change features of their organization or operation. The implications of such "real-time" changes are discussed for analyses of the operation and performance of Social/Health Maintenance Organizations over a 5-year period (2 years of start-up and enrollment and 3 years of follow-up). Analyses conducted of the plans in the context of real-time changes have to be based on different statistical models than for classic experimental study designs, where treatment factors are fixed rather than dynamic. A number of issues that may arise are identified, and possible approaches to their solutions described. Key words: long-term care; demonstrations; evaluations; study design; capitation.

A method for adjusting capitation payments to managed care plans using multivariate patterns of health and functioning: the experience of Social/Health Maintenance Organizations.

A multivariate procedure for identifying case-mix dimensions from discrete health variables is presented. Since the dimensions are generated only from health use data and not service use data, they can be used for adjust capitation rates to provide incentives to treat persons not currently well integrated in standard health care system (e.g., very ill persons, the uninsured) or to promote specific health outcomes. The procedure is illustrated with data from Social/Health Maintenance Organizations (S/HMO) since they provide both acute and long-term care (LTC) services. Thus, case-mix measures to adjust S/HMO reimbursements have to represent both medical conditions and the degree, and type, of functional impairment. From 31 health and functioning items, six case-mix dimensions, and scores for individuals on each, were calculated. The multivariate distribution of scores in S/HMO enrollees, and in Medicare eligible, comparison samples, were examined in each site to see how their health differed. S/HMO enrollees were healthier and less frail than persons remaining in the Medicare FFS system. Such differences are important in adjusting capitation rates to provide incentive to accept clients with complex health problems.

Social/health maintenance organization and fee-for-service health outcomes over time.

Evaluating the performance of long-term care (LTC) demonstrations requires longitudinal assessment of multiple outcomes where selective mortality and disenrollment, if not accounted for, can give the appearance of reduced (or enhanced) efficacy. We assessed outcomes in social/health maintenance organizations (S/HMOs) and Medicare fee-for-service (FFS) care using a multivariate model to estimate active life expectancy (ALE). S/HMO enrollees and samples of FFS clients in four sites were analyzed and outcome differences assessed for a 3-year period. Results provide insights into S/HMO performance under different conditions and, more generally, into evaluating LTC demonstrations without randomized client and control groups.

Awareness and enrollment in the Social/HMO.

Marketing the Social/Health Maintenance Organization (S/HMO) relative to HMOs and fee-for-service health insurance is a complex undertaking. Awareness of the plans is relatively high among joiners and nonjoiners, as is awareness of the relative price and benefits of these competing options. Local market competition and out-of-pocket costs appear to be major factors in selection. Study subjects include a probability sample of S/HMO members in 1986 and probability samples of elderly Medicare beneficiaries who had enrolled in HMOs or were fee-for-service recipients within the demonstration communities.
