As policymakers debate adding a prescription drug benefit to Medicare, they must also seek ways to promote cost-effective use of drugs and minimize inappropriate prescribing. For more than a decade, all state Medicaid agencies and most private insurers have used computerized drug utilization review (DUR) programs to prevent or rectify potential prescribing errors. DUR can be retrospective, in w...

BACKGROUND The Omnibus Budget Reconciliation Act of 1990 offered the promise that prospective drug utilization review (pDUR) systems would improve the quality of drug prescribing and patient drug use. There is little evidence that this promise has been fulfilled. To the contrary, there is growing evidence that suboptimal use of drugs (in terms of preventable drug-related morbidity) is at least ...

CONTEXT Retrospective drug utilization review is required of all state Medicaid programs and is performed by most private-sector prescription programs. However, it has not been shown to improve clinical outcomes or reduce the rate of potential prescribing errors, known as "exceptions." OBJECTIVE To look for an effect of retrospective drug utilization review on the rate of exceptions and of cl...

To learn to read is to acquire a visual language skill that systematically maps onto extant spoken language skills. Some children perform this task quite adeptly, while others encounter much difficulty, and it has become a question of both scientific and practical merit to ask why there exists such a range of success in learning to read. Obviously, learning to read places a complex burden on ma...

While the need for hierarchies within control systems is apparent, it is also clear to many researchers that such hierarchies should be learned. Learning both the structure and the component behaviors is a diicult task. The beneet of learning the hierarchical structures of behaviors is that the decomposition of the control structure into smaller transportable chunks allows previously learned kn...

Optimal utilization of acoustic cues during auditory categorization is a vital skill, particularly when informative cues become occluded or degraded. Consequently, the acoustic environment requires flexible choosing and switching amongst available cues. The present study targets the brain functions underlying such changes in cue utilization. Participants performed a categorization task with imm...

We have developed a haptic virtual reality system for dental skill training. In this study we examined several kinds of kinematic information about the movement provided by the system supplement knowledge of results (KR) in dental skill acquisition. The kinematic variables examined involved force utilization (F) and mirror view (M). This created three experimental conditions that received augme...

Navigating is a complex cognitive task that places high demands on spatial abilities, particularly in the absence of sight. Significant advances have been made in identifying the neural correlates associated with various aspects of this skill; however, how the brain is able to navigate in the absence of visual experience remains poorly understood. Furthermore, how neural network activity relate...
