Effect of an innovative medicare managed care program on the quality of care for nursing home residents.

PURPOSE: We sought to assess the quality of care provided by an innovative Medicare+Choice HMO targeted specifically at nursing home residents and employing nurse practitioners to provide additional primary care over and above that provided by physicians. The underlying premise of the Evercare approach is that the additional primary care will reduce the rate of untoward events and reduce the use of hospitals. Four aspects of quality were assessed: mortality, preventable hospitalizations, quality indicators derived from the Minimum Data Set, and change in functioning. DESIGN AND METHODS: The care provided by Evercare was compared with that for two control groups: (a) other residents in the same homes not enrolled in Evercare and (b) residents in homes in the same geographic area that did not participate in Evercare. Data came from various sources, including the Minimum Data Set. Utilization was based on Medicare data for controls and United Healthcare data for Evercare residents. Survival analysis was used to estimate mortality rates. Various risk adjustment methods were applied to the quality indicators. RESULTS: The hazard rates of mortality were significantly lower for Evercare residents than for other residents in the same nursing homes. Evercare residents had fewer preventable hospitalizations; the difference was significant for one control group. The rates of quality indicators and functional change were equivalent. IMPLICATIONS: Evercare, with its use of nurse practitioners, represents a model that can provide more efficient care that is of at least comparable quality.

The effect of Evercare on hospital use.

OBJECTIVES: To examine the use of hospital and related medical care services of a novel managed care program using nurse practitioners (NPs) and directed specifically at long-stay nursing home residents. DESIGN: Quasi-experimental posttest design with two control groups to minimize selection bias. SETTING: Nursing homes. PARTICIPANTS: Evercare enrollees in five sites were compared with two sets of controls: nursing home residents in the same nursing homes who did not enroll in Evercare (control-in) and residents of nursing homes that did not participate in Evercare (control-out). MEASUREMENTS: Utilization data from Medicare and United Healthcare (the parent corporation for Evercare) were obtained for slightly more than 2 years. Patterns of use were assessed by calculating the monthly use rate for each group and aggregating to form annual rates. Usages addressed included hospital admissions and days, emergency room visits, therapy services, mental health services, and podiatry. Adjustments were made to correct for age, race, and sex. Because the groups differed in terms of the rate of cognitive impairment, the analysis was stratified on this variable. RESULTS: The incidence of hospitalizations was twice as high in control residents as in Evercare residents (4.63 and 4.67 per 100 enrollees per month vs 2.43 in the 15 months after census, P<.001). This difference corresponded to Evercare's use of intensive service days. The same pattern held for preventable hospitalizations (0.80 and 0.86 vs 0.28, P<.001). The pattern held when residents were stratified by cognitive status. On average, using a NP is estimated to save about $103,000 a year in hospital costs per NP. CONCLUSION: The use of active primary care provided by NPs may have prevented the occurrence of some hospitalizable events, but its major effect was allowing cases to be managed more cost-effectively.

Nursing home residents covered by Medicare risk contracts: early findings from the EverCare evaluation project.

OBJECTIVES: To compare the characteristics of a sample of EverCare nursing home residents with two control groups: one composed of other residents in the same homes and another made up of residents in matched nursing homes. To compare levels of unmet need, satisfaction with medical care, and the use of advance directives. DESIGN: Quasi-experimental design using two control groups to minimize selection effects. Information collected by in-person surveys of nursing home residents and telephone surveys of proxies and family members. SETTING: Nursing homes affiliated with EverCare and matched control homes. PARTICIPANTS: Nursing home residents and their family members. MEASUREMENTS: Questionnaire addressing function (activities of daily living (ADLs)), unmet care needs, pain, use of advance directives, satisfaction, and caregiver burden. RESULTS: In general, the experimental and control groups were similar, but the EverCare sample had more dementia and less ADL disability. Family members in the EverCare sample expressed greater satisfaction with several aspects of the medical care they received than did controls. Satisfaction of residents in the EverCare sample was more comparable with that of controls. There was no difference in experience with advance directives between EverCare and control groups. CONCLUSIONS: EverCare appears to be a model of managed care worth tracking. It is producing care that is at least comparable with what is available in the fee-for-service environment, with evidence that families seem to appreciate the added attention. There is some suggestion that it has enrolled a less disabled but more demented population. Pending results on the effects of this care on hospitalization and emergency care should shed useful light.
