these programs complemented but did not substitute for nursing home care. Later
research showed that those who used community-based services in general
needed and benefited from them, but they did not have lower rates of nursing
home admission, and use of community-based care actually raised overall health
care costs (Weissert et al., 1988). Weissert also reported that when there was re-
duction in nursing home utilization, the savings were usually small, and commu-
nity services had a limited effect in producing changes in health status.

Case management is an emerging supportive service that facilitates access to ap-
propriate health and social services for high-risk older adults and their caregivers
through assessment, counseling, and advocacy (Raiff & Shore, 1993; Scharlach,
Giunta, & Mills-Dick, 2001). A major strength of case management is its ability to
transcend traditional health care boundaries by coordinating and linking services
across medical, behavioral, and social service environments. Yet despite the
prevalence of case management practice, there has been little evidence of efficacy
and effectiveness in application of these models. What studies do exist on case
management models with older adults often lack rigor or contain methodological
weaknesses that result in questionable findings (Lee & Tuljapurkar, 1998). In the
past few years, several studies on the efficacy of case management with older
adults have been conducted using experimental designs with randomized control
groups (Boult et al., 2000; Engelhardt et al., 1996; Fordyce, Bardole, Romer,
Soghikian, & Fireman, 1997; Gagnon, Schein, McVey, & Bergman, 1999; Leveille
et al., 1998; Marshall, Long, Voss, Demma, & Skerl, 1999; Morishita, Boult, Boult,
Smith, & Pacala, 1998; Naylor et al., 1999; Schore, Brown, & Cheh, 1999; Weuve,
Boult, & Morishita, 2000). These projects aimed to improve health and daily func-
tioning, reduce medical service use, decrease rates of depression, and increase
client satisfaction, among other goals. Results of these studies are consistently in-
consistent; some reported decreased rates of service use (Leveille et al., 1998;
Naylor et al., 1999), and others reported no difference in or increased service use
for those receiving this service (Boult et al., 2000; Fordyce et al., 1997; Gagnon
et al., 1999; Long & Marshall, 1999; Schore et al., 1999). Similarly, levels of satis-
faction and functioning for the case management group were also inconsistent
across studies (Gagnon et al., 1999; Marshall et al., 1999; Morishita et al., 1998).
Moreover, none of the studies measuring depression level were actually able to
impact depression through their interventions (Engelhardt et al., 1996; Leveille
et al., 1998; Naylor et al., 1999).
Current Models of Case Management The most prevalent case management models
serving older adults with chronic conditions utilize managed care systems to
achieve their goals of improving quality of care and quality of life and cost sav-
ings. Here we summarize findings on a number of these models, including the
PACE program, S/HMO, and case management models that link managed health
care with community agencies.
The premise of the PACE model is that through monthly fixed payments from
Medicare and Medicaid (for those dually eligible) or through private pay, ser-
vices can be expanded beyond what is traditionally provided by either Medicare
