Brotman, M.D., an associate professor of medicine at the Johns Hopkins University School of Medicine and director of the hospitalist program at The Johns Hopkins Hospital. “There is definitely an over-ordering of tests in this country, and we can make better decisions about whether our patients truly need each test we order for them. But when it comes to big-ticket tests like MRI, it appears the doctors have already decided they need to know the information, regardless of the cost of the test.”Studies in the past suggest that much of the expense of laboratory tests, medical imaging and prescription drugs is unknown or hidden from providers and patients at the time of ordering, leaving financial considerations largely out of the health care decision-making process and likely driving up costs, Brotman notes.Other studies have shown that doctors ordered fewer laboratory tests in some cases when they were given the price up front. But Brotman says imaging tests appear to be “a different animal.”There are built-in disincentives to ordering many major tests if they are not necessary, such as the potential danger of radiation used in some, Brotman says. In addition to making physicians more sensitive to the costliness of unnecessary testing, Brotman says they need to learn how to explain to patients why they may not need them.For the study, Brotman and his colleagues identified the 10 imaging tests most frequently ordered for patients at The Johns Hopkins Hospital. Dividing the tests into two groups, they made sure prices were attached to one group over a six-month period, from November 2009 to May 2010. Brotman and his colleagues left out the pricing information for the other group over the same time period. Prices are not typically shared with physicians or patients in most medical settings.When the researchers compared the ordering rates to the rates from a six-month period a year earlier, when no costs were displayed at all, they found no significant difference in ordering patterns.Brotman says he might have been concerned if there was a large decrease in ordering expensive tests, as there are many instances when the expensive test is justified. For example, when a patient appears to have had a sub-acute stroke, an MRI is often justified “regardless of cost,” he says. “When a key diagnosis is needed in imaging, there are limited options for comparison shopping.”That is not to say there are not times when physicians need to look more closely at whether too many imaging tests are being ordered, Brotman says. For example, patients in a hospital intensive care unit who are on a ventilator and unable to tell doctors how they are feeling may not need a daily chest X-ray to scan for potential problems. Brotman says there is evidence that outcomes are not compromised if X-rays are ordered only when the patient’s condition appears to be worsening. MRIs are also ordered too frequently for lower back pain, he says.“For too long, there has not been enough attention paid to the bottom line in health care,” Brotman says. This is not about rationing care to hold down costs, he says, but about choosing tests a little more wisely. “There are financial consequences for the choices we make, and for too long we haven’t considered them,” he says.Even though price transparency did not influence the way physicians ordered imaging tests in his study, Brotman says financial considerations may play a role in other circumstances if tied to clinical evidence.For example, he says, when clinical programs began to compare the amount of blood products used by surgeons, those who were using far more than their peers (and with similar patient outcomes) took note and reduced their reliance on transfusions, which are not only costly but also carry risks.If you show a provider that he or she is ordering four times as many computed tomography (CT) scans as a colleague whose patients have similar outcomes, it could change the decision-making calculus for the better, he says.“Cost transparency must be part of the solution to solving fiscal challenges in medicine,” Brotman says. “Providers have no idea how much they’re spending. Patients don’t know either. Having everyone understand more of the economics of health care is a great place to start cutting costs in medicine.”The study was supported, in part, by the Research and Education Foundation of the Radiological Society of North America, the Walter and Mary Ciceric Research Award and the Johns Hopkins Hospitalist Scholars Program.Other Johns Hopkins researchers involved in the study include Daniel J.

TUNIS, Tunisia (AP) – A former prime minister who led Tunisia’s transition government after the fall of its autocratic leader has launched a new political party to counter-balance the Islamists running the North African country.Beji Caid Essebsi announced the formation of the Nida’ Tounes, or Call of Tunisia, party on Saturday before thousands of men and women _ including a number of artists _ in a packed hall. The 85-year-old said he wants a party “that unifies everyone, without exclusion.” He called it a “balancing force that can create conditions for an alternative.” The moderate Islamist Ennahda party was elected after a transition period following the January 2011 ouster of Zine El Abidine Ben Ali. However, hardline Islamists are emerging and last week clashed with police over an art exhibit they judged blasphemous.(Copyright 2012 The Associated Press. All rights reserved.
