Patient trust has been identified as an important element in the patient-ph
ysician relationship. However, common features of managed care, such as ris
k-sharing, utilization review, and limitations on benefits, may erode the t
raditionally high trust that patients have in their physicians. High trust
is not always justified; rather, an optimal level of trust: arises from the
level of interdependence between patients and physicians. This analysis of
the interrelationship between patient-physician trust and some of the key
facets of managed care has important implications for managed care. A retur
n to high levels of trust may be impracticable, and new strategies for bala
ncing trust-building efforts by caregivers with checking mechanisms accessi
ble to patients are recommended.
