Increasing clinical evidence has validated the utility of CTAP in a variety of clinical settings. As a result, the utilization of CTAP has increased in recent years, in both the ED and a variety of other settings, resulting in questions regarding the appropriateness of its utilization.
"Understanding the complexity of patient encounters in which advanced medical imaging services are frequently delivered might be useful in aiding payers and policymakers in explaining the growth of advanced imaging services over the past decade and determining the context in which these examinations are appropriately being used," said Richard Duszak, Jr., MD, co-author of the study.
Using the CMS five percent Medicare files for 2007, ED visits for Medicare fee-for-service beneficiaries were identified. Contemporaneous ED physician evaluation and management codes were used as the basis for patient complexity categorization. Encounters in which CTAP was performed on the same date of service were identified, and variables affecting the utilization of CTAP were analyzed.
Results showed that of 1,081,000 ED encounters, 306, 401 (28.3 percent) were of lower complexity and 774, 599 (71.7 percent) were of higher complexity. CT of the abdomen and pelvis was performed in 65,273 of all encounters (6.0 percent), corresponding to 4,069 (1.3 percent) of lower complexity and 61,204 (7.9 percent) of higher complexity encounters. Of the 65,273 encounters associated with CTAP, 61,204 (93.8 percent) were of higher complexity.
"The utilization of advanced medical imaging in the ED setting serves many valuable roles. CT of the abdomen and pelvis can facilitate patient triage, decrease ED patient waiting times, decrease hospital lengths of stay and reduce the need for exploratory surgery. These outcomes would favor a preferential role for CTAP in sicker and more complex patients, and our results support that belief," said Duszak.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
