The APP processing in platelets of patients with AD is different from that of control subjects. This difference, largely caused by factors other than the ApoE4 genotype, may reflect chronic platelet activation in patients with AD. The use of these data to estimate "AD risk," by using the APP isoform ratio, indicates an odds ratio of 1.75, suggesting possible utility as an adjunct in the diagnosis of AD. Moreover, these findings may relate to analogous alterations in APP processing that may occur in brain areas affected by AD.

Current Medicare capitation payments to managed care plans may not meet the higher expected annual costs of care for beneficiaries with DAT. In turn, physicians (or physician groups) who accept capitation for Medicare beneficiaries with DAT should also consider how capitation rates are established by managed care plans and should learn ways to reduce financial risk.

Physicians and nurses had markedly different views about effects of a POE system on patient care, highlighting the need to consider both perspectives when assessing the impact of POE. With this POE system, most nurses saw beneficial effects, whereas many physicians saw negative effects.
