abstract = {Long-term evidence for the effectiveness and
cost-effectiveness of collaborative dementia care management
(CDCM) is lacking.To evaluate whether 6 months of CDCM is
associated with improved patient clinical outcomes and
caregiver burden and is cost-effective compared with usual
care over 36 months.This was a prespecified secondary
analysis of a general practitioner (GP)-based, cluster
randomized, 2-arm clinical trial conducted in Germany from
January 1, 2012, to December 31, 2014, with follow-up until
March 31, 2018. Participants were aged 70 years or older,
lived at home, and screened positive for dementia. Data were
analyzed from March 2011 to March 2018.The intervention
group received CDCM, comprising a comprehensive needs
assessment and individualized interventions by nurses
specifically qualified for dementia care collaborating with
GPs and health care stakeholders over 6 months. The control
group received usual care.Main outcomes were
neuropsychiatric symptoms (Neuropsychiatric Inventory
[NPI]), caregiver burden (Berlin Inventory of Caregivers'
Burden in Dementia [BIZA-D]), health-related quality of life
(HRQOL, measured by the Quality of Life in Alzheimer Disease
scale and 12-Item Short-Form Health Survey [SF-12]),
antidementia drug treatment, potentially inappropriate
medication, and cost-effectiveness (incremental cost per
quality-adjusted life year [QALY]) over 36 months. Outcomes
between groups were compared using multivariate regression
models adjusted for baseline scores.A total of 308 patients,
of whom 221 $(71.8\%)$ received CDCM (mean [SD] age, 80.1
[5.3] years; 142 $[64.3\%]$ women) and 87 $(28.2\%)$
received usual care (mean [SD] age, 79.2 [4.5] years; 50
$[57.5\%]$ women), were included in the clinical
effectiveness analyses, and 428 (303 $[70.8\%]$ CDCM, 125
$[29.2\%]$ usual care) were included in the
cost-effectiveness analysis (which included 120 patients who
had died). Participants receiving CDCM showed significantly
fewer behavioral and psychological symptoms (adjusted mean
difference [AMD] in NPI score, -10.26 $[95\%$ CI, -16.95 to
-3.58]; P = .003; Cohen d, -0.78 $[95\%$ CI, -1.09 to
-0.46]), better mental health (AMD in SF-12 Mental Component
Summary score, 2.26 $[95\%$ CI, 0.31-4.21]; P = .02; Cohen
d, 0.26 $[95\%$ CI, -0.11 to 0.51]), and lower caregiver
burden (AMD in BIZA-D score, -0.59 $[95\%$ CI, -0.81 to
-0.37]; P < .001; Cohen d, -0.71 $[95\%$ CI, -1.03 to
-0.40]). There was no difference between the CDCM group and
usual care group in use of antidementia drugs (adjusted odds
ratio, 1.91 $[95\%$ CI, 0.96-3.77]; P = .07; Cramér V,
0.12) after 36 months. There was no association with overall
HRQOL, physical health, or use of potentially inappropriate
medication. The CDCM group gained QALYs (0.137 $[95\%$ CI,
0.000 to 0.274]; P = .049; Cohen d, 0.20 $[95\%$ CI, -0.09
to 0.40]) but had no significant increase in costs (437€
[-5438€ to 6313€] [US $476 (95\% CI, -$5927 to $6881)];
P = .87; Cohen d, 0.07 [95\% CI, -0.14 to 0.28]), resulting
in a cost-effectiveness ratio of 3186€ (US $3472) per
QALY. Cost-effectiveness was significantly better for
patients living alone (CDCM dominated, with lower costs and
more QALYs gained) than for those living with a caregiver
(47 538€ [US $51 816] per QALY).In this secondary analysis
of a cluster randomized clinical trial, CDCM was associated
with improved patient, caregiver, and health system-relevant
outcomes over 36 months beyond the intervention period.
Therefore, it should become a health policy priority to
initiate translation of CDCM into routine
care.ClinicalTrials.gov Identifier: NCT01401582.},
