A survey was undertaken to examine the impact of Medicare's Prospective Payment System (PPS) and other recent changes in the health care environment on providers' decisions regarding acquisition of high-cost technologic equipment. The survey group included 199 hospitals and freestanding imaging centers known to have acquired magnetic resonance (MR) imaging units, as well as a random sample of 400 hospitals whose acquisition decisions were unknown to the authors. Fifty-eight percent of the known adopters and 61% of the randomly selected hospitals responded to the survey. Nonadopters' decisions were dominated by economic considerations, including the high cost of MR imagers and concerns about Medicare's reimbursement policies. Competition and a desire to provide the highest quality of care are counterbalancing the retardant effects of PPS, however, and are stimulating widespread diffusion of MR imagers. 相似文献

Radiology conferences enable participants the opportunity to ask experts questions through question and answer (Q and A) sessions
or individually. Given the time limitations and intimidating circumstances, we incorporated conference text messaging (confexting)
as a method of increasing interactivity between the audience and speakers. During a 5-day radiology conference, text messaging
was utilized for anonymous interactivity between the audience and speakers during Q and A sessions. There were 324 text messages;
76 of these were either follow-up statements or questions related to earlier text messages. Forty-two questions were submitted
via paper notes. There was a general trend of an increasing number of text messages and a decreasing number of paper notes.
The anonymous text messaging system was found to be an effective method for interactivity between the audience and the speakers.
The questions and answers could be presented in a PowerPoint format at the formal Q and A sessions. Questions texted to the
authors during their talks could be immediately answered or addressed in subsequent talks. Although difficult for some individuals
to embrace technology, confexting allows for interactivity and prompts discussion. Confexting is an effective method for interactivity
between the audience and speakers not previously utilized in a conference setting. The anonymity and asynchronous communication
enable conference participants to submit more questions than in the traditional setting. The speakers may be able to explain
more thoroughly difficult concepts more thoroughly with additional slides at Q and A sessions or may immediately answer texted
questions during their talks. 相似文献

The Brazilian Diabetes Society is starting an innovative project of quantitative assessment of medical arguments of and implementing a new way of elaborating SBD Position Statements. The final aim of this particular project is to propose a new Brazilian algorithm for the treatment of type 2 diabetes, based on the opinions of endocrinologists surveyed from a poll conducted on the Brazilian Diabetes Society website regarding the latest algorithm proposed by American Diabetes Association /European Association for the Study of Diabetes, published in January 2009.An additional source used, as a basis for the new algorithm, was to assess the acceptability of controversial arguments published in international literature, through a panel of renowned Brazilian specialists. Thirty controversial arguments in diabetes have been selected with their respective references, where each argument was assessed and scored according to its acceptability level and personal conviction of each member of the evaluation panel.This methodology was adapted using a similar approach to the one adopted in the recent position statement by the American College of Cardiology on coronary revascularization, of which not only cardiologists took part, but also specialists of other related areas. 相似文献
