OAK BROOK, Ill. Despite concerns to the contrary, very little of the variation in Emergency Department (ED) imaging utilization is attributable to physician experience, training or gender, according to a new study published online in the journal Radiology.

Imaging exams like X-rays and CT scans are common in the ED. In 2010, slightly more than 47 percent of all ED visits in the United States had an imaging exam associated with them.

"Analyzing and understanding drivers of use of imaging in the ED is important for several reasons," said Christopher L. Sistrom, M.D., M.P.H., Ph.D., from the departments of radiology at Massachusetts General Hospital in Boston and the University of Florida in Gainesville, Fla. "There's a balance of cost and benefits to the patient, institution and payer, as well as the overarching issue of radiation exposure."

Previous studies have found substantial variation in imaging rates across and within EDs, suggesting different tendencies among physicians when ordering imaging. However, much of the existing research is limited, according to Dr. Sistrom.

"A lot of literature on imaging variability can lead to a false assumption that doctors are primarily responsible," he said. "The problem is that it is difficult to fully describe and quantify variability at the different levels it can occur."

In the new study, Dr. Sistrom and colleagues analyzed 88,851 ED visits during 2011 at Massachusetts General Hospital. They used an analytical tool known as hierarchical logistic regression to identify multiple predictors of the probability that imaging was ordered during a given visit.

"That's what makes our paper unique," Dr. Sistrom said. "Hierarchal modeling allows us to ask very specific questions about the relative contributions of various factors to imaging use."

The overall rate of imaging utilization in the Massachusetts General ED was 45.4 percent in 2011, similar to the 2010 national average of 47.2 percent. Analysis of the data revealed that physician-related factors like gender, experience and training did not correlate with imaging use.

"The key finding in our study is that doctors don't make much difference in imaging utilization," Dr. Sistrom said. "Our data showed that doctors are responsible for about one percent of the variability in probability of having an imaging exam during an ED visit."

Instead, patient and visit factors were the predominant predictors of the likelihood of imaging for a given ED visit. These factors include prior visit, referral source, arrival mode and clinical reason for the visit.

The workload of the ED was another significant factor in imaging use. When the ED was the least busy, the odds of low-cost imaging were 11 percent higher than the reference standard. A busier ED resulted in a tendency towards more high-cost imaging.

The new study shows that medical management efforts looking to reduce imaging utilization may be misguided in focusing on remediating ED physicians.

"To reduce imaging utilization, a lot of people in quality improvement and medical management might try to identify high outliers and punish them," Dr. Sistrom said. "In settings like the one we studied, that strategy won't get you anything but angry doctors."

'Bing for Schools' tailors Microsoft's search engine to K-12, cuts ads and filters adult content

Bing is headed to the classroom in a more targeted form, with Redmond announcing this morning a new version of the engine dubbed "Bing for Schools." The initiative takes the standard Bing search engine and cuts all adverts in search, filters "adult content" (the specifications of that are murky) adds more privacy protection, and adds "specialized learning features to enhance digital literacy." Schools can opt in on a per-case basis, and if they do, that will enable the specialized version of Bing on an entire school's network. The program's kicking off "later this year," and interested parties can put their name in the hat right here. Should you like to see the full note introducing Bing for Schools from Microsoft's Bing Behavioral Scientist Matt Wallaert, we've dropped it just beyond the break.

Families skeptical of Pratt cancer study findings

HARTFORD, Conn. (AP) -- For jet engine maker Pratt & Whitney, a long-simmering dispute over worker illnesses was settled by a massive 11-year study that found no elevated risk of brain cancer at its plants. But for dead workers' relatives who first raised concerns years ago, the matter is far from closed.

Their next step hasn't been decided, and the choices are limited. Matt Shafner, a New London lawyer who represents families, said more than 90 workers' compensation claims have been filed. But he won't move forward until an independent review of the study is completed, he said.

"It's not over," said Carol Shea, whose husband, John Shea, worked at Pratt & Whitney's North Haven plant for 35 years and died of brain cancer in 2000 at age 56.

Some relatives of workers who died of brain cancer a decade or more ago are dissatisfied with the study, saying it failed to prove that the deaths of their loved ones were part of a broader problem.

Todd Atcherson, whose father, Charles Atcherson, died in 1998 after working at Pratt & Whitney for about 25 years, said the enormous scope of the study ? health and work records of more than 200,000 employees were reviewed ? fail to explain the deaths of his father and a small group of other workers at the North Haven plant.

"They skewed out the numbers so far, they lost focus of five people who worked in the same site and all died," he said.

Shea said she believes the researchers are "way off."

"I couldn't believe they couldn't come up with anything," she said.

The study, released last month, was launched "in response to the perception of an unusual occurrence" of glioblastoma, a common and aggressive malignant brain tumor, at the North Haven plant. It found the incidence rates of glioblastoma at the site weren't related to workplace exposures.

The environment at the plant featured a blue haze, a product of aerosol generated from metalworking fluids during fast, hot grinding.

The study, which examined seven other Pratt & Whitney plants in Connecticut, found no statistically significant elevations in the rate of cancer among workers. Researchers at the University of Pittsburgh and University of Illinois at Chicago said they identified 723 workers diagnosed with tumors between 1976 and 2004 at the subsidiary of United Technologies Corp.

The tumors were malignant, benign or unspecified and included 277 cases of brain cancer. Of those, 167 were at Pratt & Whitney's East Hartford site and 57 at North Haven, though North Haven workers were at greater risk of having brain cancer, the study said.

But following a study of the North Haven plant, researchers said they couldn't conclude that the environment or exposures were related to the overall elevations in brain cancer.

Gary Marsh, the University of Pittsburgh researcher who led the study, said that he understands family members' frustrations but that the study is conclusive and definitive.

"Let's face it: Brain cancer is a terrible disease and anyone who suffers from it or had a loved one suffer from it wants to know why they got that disease," he said. "We looked at everything conceivable as a possible cause of brain cancer."

Ray Hernandez, a spokesman for Pratt & Whitney, said the company is satisfied with the study's conclusions and considers the matter closed.

"Since we are confident in the scientific rigor of this comprehensive study, we think it provides the best possible information about this issue," he said in an emailed statement.

The study found no connection between brain cancer and the workplace and researchers found no patterns or trends of other causes of death "suggestive of a workplace relationship," Hernandez said.

In Connecticut, Pratt & Whitney over the years has shut down all but its Middletown and East Hartford plants. Manufacturing processes from decades ago have been transformed and haven't recently raised safety issues.

A few family members said they are wary of the study because it was commissioned by Pratt & Whitney at a cost of $12 million. The university researchers worked independently of Pratt & Whitney and the state Department of Public Health established an advisory group to review the progress, methods and other aspects of the study and address concerns about the study's independence.

John DeLeone, a grinding machine operator at the North Haven plant from 1984 until it closed in 2002, said workers suspected that chemicals specific to that plant were lethal. He criticized the study, which was launched in 2002 in response to concerns about employee deaths at North Haven, for being overly broad rather than focusing on that plant.

"It seemed that only people who got sick were those who transferred from North Haven," he said.

Marsh said the study adds to the body of knowledge of occupational health, used by researchers and relevant to other jet engine manufacturers, such as General Electric Co. and Rolls Royce, he said.

"We concluded there is no evidence of elevated health risks of this population. That's a good thing to know," he said.

But Debra Belancik, the Machinists' union's safety and health representative, said the study "doesn't bring any closure at all."

"All this work we did, all the high rates, all the funerals and wakes I went to, it kind of bothered me a little bit," she said.

'Mad Men's' Don Draper: Sexy, but so sad

TV

Anna Chan TODAY

10 hours ago

Michael Yarish / AMC

Don Draper found himself surrounded by people, yet all alone and sad, in the ninth episode of the season, titled "Better Half."

It's been a long, sad season for Don Draper on "Mad Men." It seemed almost every episode featured at least one shot of the handsome ad man brooding -- and in some cases, even shedding a tear or two.

What's he got to cry about, you say? We hear you: He's a rich, very successful, good-looking guy with a gorgeous wife. As far as viewers can see, he's still got his health too. (At least, we think so. His liver hasn't started failing from all that drinking yet, right?) So why the long face, Don?

Turns out maybe we should cut the guy a little slack. Money and good looks can't buy happiness, after all. (Just a lot of other stuff that makes life a bit easier.)

Dumped
Nobody tells Don Draper what's what! Unless you're his neighbor/mistress, apparently. In the episode titled "Man With a Plan," the ad man does his own version of "50 Shades of Grey" and orders lover Sylvia to stay in her hotel room all day (although it felt more like days), even taking away her book at one point. By the end of that ordeal, she'd had an epiphany and dumped him. His response? Disbelief. Sad face. Begging. And later, more begging on the phone.

Who are you?
Daughter Sally delivered a knife to Don's -- and viewers' -- hearts this year. After the Draper residence is burgled while the adults are away and Sally was left behind to watch her little brothers, she explained to Don why she was duped into believing the thief -- a black woman -- was her grandma. "She said she knew you," Sally told her dad on the phone later. "I asked her everything I know and she had an answer for everything. Then I realized I don't know anything about you." Sad, ponderous face.

All by himself
Don's often surrounded by people, whether he's at the office, having a meal with clients or enjoying a little tryst with someone. When he hooked up with ex-wife Betty while visiting son Bobby at camp, he admitted that he'd missed her, hinting at how unhappy he is in his current marriage. "Why is sex the definition of being close to someone?" he asked. Her reply? "I don't know. But it is for me, it is for most people." Cue the sad face. And by the next morning, they were miles apart again. As Don headed into the diner for breakfast, he saw Betty sitting with her husband, Henry ... and Don shuffled off to sit alone.

Drowning
After smoking some hashish at a Hollywood party, Don started to hallucinate first the happy, then the sad. The vision of a pregnant Megan came to him first, then Dinkins, the soldier he met in the season premiere. Except now, the young man is missing an arm -- and is dead. "Dying doesn't make you whole," Dinkins told Don when asked why the deceased vet was still missing his appendage in the afterlife. "You should see what you look like." And what does the ad man look like? Depressed. And dead. Floating in a pool face-down dead. But fortunately for him, the dead part was a hallucination, but he really was drowning in the pool until Roger dove in and saved him.

Busted
When Don finally got caught cheating with Sylvia, it wasn't by who viewers -- or Don himself -- were probably expecting. It was Sally who walked in on the two lovebirds. This sent Don first into panic mode, which eventually morphed into depression. It became obvious two episodes later, when Don started out the penultimate episode of the season curled up in a fetal position on Sally's bed, and ended the hour the same way, realizing that his actions have cost him a relationship with his little girl.

What Sunday's finale holds for Don's happiness, you'll have to tune in and see at 10 p.m. on AMC.

Zimmerman judge: No testimony on 911 call screams

SANFORD, Fla. (AP) ? The judge in the murder trial of George Zimmerman said Saturday that prosecution audio experts who point to Trayvon Martin as screaming on a 911 call moments before he was killed won't be allowed to testify at trial.

The screams are crucial pieces of evidence because they could determine who the aggressor was in the confrontation before Zimmerman fatally shot the unarmed teenager. Martin's family contends it was the teen screaming, while Zimmerman's father has said it was his son.

Judge Debra Nelson ruled that the methods used by the experts aren't reliable. But her ruling doesn't prevent the 911 calls from being played at trial.

She reached the decision after hearing arguments that stretched over several days this month on whether to allow testimony from two prosecution experts. One expert ruled out Zimmerman as the screamer and another said it was Martin. Defense experts argued there was not enough audio to determine who the screams are coming from. Zimmerman's attorneys also argued that the state experts' analysis is flawed.

Opening statements are set for Monday in the second-degree murder trial for the former neighborhood watch volunteer who says he fired on the black teenager in self-defense last year. Zimmerman is pleading not guilty.

The elimination of the audio experts will likely shorten the trial by a week. Before the ruling, attorneys had predicted the trial could last two to four weeks after opening statements.

A spokeswoman for prosecutors didn't immediately return an email Saturday.

Audio experts from both sides testified at different times during the hearing, which stretched over three weeks. Voice experts were hired by lawyers and news organizations to analyze the calls, which were made during the confrontation between the two. The experts arrived at mixed conclusions.

In deciding whether to admit the voice-recognition technology used by prosecution audio experts Tom Owen and Alan Reich, Nelson had to determine whether it is too novel or whether it has been accepted by the scientific community at-large.

"There is no evidence to establish that their scientific techniques have been tested and found reliable," the judge said in her ruling.

Owen was hired by the Orlando Sentinel last year to compare a voice sample of Zimmerman with screams for help captured on 911 calls made by neighbors. He said Zimmerman's voice doesn't match the screams. He only compared Zimmerman's voice to the 911 calls because he didn't have a voice sample for Martin at the time.

"The screams don't match at all," Owen testified during the hearing. "That's what tells me the screams aren't George Zimmerman."

Owen also testified that remarks Zimmerman made in a conversation with a police dispatcher aren't a racial slur. He testified Zimmerman said, "These f------ punks."

Reich testified in a report for prosecutors that the screams on the 911 tapes were from Martin, and the defense does not want him to testify at trial.

Reich's analysis also picked up words that other experts couldn't find. They include the words, "This shall be" from Zimmerman and "I'm begging you" from Martin.

Reich's testimony would "confuse issues, mislead the jury," the judge said.

In contrast, a British audio expert testified for the defense that it would be extremely difficult to analyze voices by comparing screaming to a normal voice.

"I've never come across a case in my 13 years where anybody's tried to compare screaming to a normal voice," said audio expert Peter French.

A second audio expert for the defense, George Doddington, also criticized prosecution experts who said Friday that screams and pleas on a 911 recording likely belonged to Martin.

"It's all ridiculous," Doddington said.

Government on offensive outside Syria's capital

BEIRUT (AP) ? Syrian government forces stepped up their attack against rebel strongholds north of the capital Damascus on Saturday, while opposition fighters declared their own offensive in the country's largest city Aleppo.

Both sides intensified operations as an 11-nation group that includes the U.S., dubbed the Friends of Syria, began meeting in Qatar to discuss how to coordinate military and other aid to the rebels seeking to oust Syrian President Bashar Assad.

Friends of Syria agreed on Saturday to do more to help the embattled rebels trying to overthrow Assad, U.S. Secretary of State John Kerry said. While he offered no specifics about stepped-up military and humanitarian aid, Kerry said the assistance would help change the balance on the battlefield.

Kerry also denounced Assad for inviting Iranian and Hezbollah fighters to fight alongside his troops, saying the Syrian president risked turning the civil war into a regional sectarian conflict.

The fighting in Damascus came as the Syrian government announced salary increases to state employees and members of the military, days after the Syrian currency dipped to a record low of 210 pounds to the dollar compared with 47 when the crisis began more than two years ago. The raise also covered pensions.

The Britain-based Syrian Observatory for Human Rights, which relies on an extensive network of activists in Syria, said the shelling of the district of Qaboun has killed three children, including two from the same family, since Friday.

Activists reported heavy shelling on many fronts on districts north of Damascus, apparently an attempt to cut links between rebel-held districts that have served as launching pads for operations against the capital.

The Lebanese TV station Al-Mayadeen, which had a reporter embedded with Syrian government forces in the offensive, quoted a military official as saying that the operation aims to cut rebel supply lines, separate one group from another, and secure the northern entrances to the capital. The regime's forces have struggled for months to regain control of these suburbs.

The Observatory said the neighborhood was being attacked from several different sides, while the shelling has caused structural damage and started fires. Activists from Qaboun posted on Facebook that government forces had brought up new tanks to reinforce its positions outside the neighborhood, and the bombardment had brought buildings down.

The Observatory said rebels targeted a police academy in the nearby Barzeh area Saturday, pushing back against a government attempt to storm the neighborhood. One rebel was killed in overnight fighting, it said.

State news agency SANA said troops "inflicted heavy losses" among rebels in several suburbs of Damascus.

A recent declaration by the U.S. that it had conclusive evidence that President Bashar Assad's regime used chemical weapons on a small scale against opposition forces prompted Washington to authorize the arming of rebels, a major shift in policy. The decision also followed advances by the government forces aided by fighters from Lebanon's Hezbollah.

Rebels say they have already received new weapons from allied countries? but not the U.S. ? that they claim will help them to shift the balance of power on the ground. Experts and activists said the new weapons include anti-tank missiles and small quantities of anti-aircraft missiles.

It was not clear if any of the new weapons have made it to the Damascus area. A spokesman for one of the main groups fighting outside of Damascus, the al-Islam brigade, said his group had none of the new weapons. The spokesman, who declined to be named for fear of government reprisals, spoke to The Associated Press through Skype.

He said government forces were shelling Barzeh from Qasioun mountain overlooking Damascus. Syria's main Western-backed opposition group said Thursday that 40,000 civilians in the two northern districts of Damascus are suffering from shortages of food and medical supplies.

Rebels and government also clashed in and around the northern city of Aleppo, where government forces announced an offensive earlier this month. Activists said troops clashed in the southern neighborhoods of Rashideen and Hamdaniya and in the western suburbs.

The Observatory said rebels pounded a military academy in the area, causing a fire in the compound. There were no immediate reports of casualties. In Rashideen, rebel forces have pushed government forces out from parts of the neighborhood, according to the local Aleppo Media Center network and posts on Facebook.

A statement by a coalition of rebel groups, posted on the Center's page, declared that the fighters are launching a new operation to seize control of the western neighborhoods of Aleppo. Amateur showed what appeared to be intense government shelling of villages in the area.

On Saturday, a dozen shells from Syrian forces landed in a northern Lebanese border town, some landing near homes, causing a panic among residents, the Lebanese news agency reported.

Syria's official news agency said government troops were targeting a group of infiltrators across the border. It gave no further details.

Rockets from Syria fall regularly into towns and villages near the border. On Friday, a rocket slammed into a suburb of Beirut, bringing the war closer to Lebanon's bustling capital, the second in less than a month. No one claimed responsibility for that attack, but rebels in Syria have vowed to retaliate against Hezbollah's Beirut strongholds for its increasingly active role assisting Assad.

In Damascus, a presidential decree said that the raise for the public sector could reach up to 40 percent depending on the salary of the civil servant. Pensions could rise by up to 25 percent, according to the decree.

It said those who make 10,000 pounds ($54) a month will get a 40 percent raise, while who make double that amount will get a 20 percent boost. People making 40,000 pounds a month will get a 5 percent raise, it said.

Syria's 2-year civil war has killed nearly 93,000 people. It increasingly pits Sunni against Shiite Muslims and threatening the stability of Syria's neighbors.

Obama to meet with privacy, civil liberties board

WASHINGTON (AP) ? President Barack Obama is holding his first meeting with a privacy and civil liberties board Friday as he seeks to make good on his pledge to have a public discussion about secretive government surveillance programs.

Obama has said the little-known Privacy and Civil Liberties Oversight Board will play a key role in that effort. The federal oversight board reviews anti-terror programs to ensure that privacy concerns are taken into account.

The president is also tasking the director of national intelligence, James Clapper, to consider declassifying more details about the government's collection of U.S. phone and Internet records. Obama is specifically asking Clapper to review possible declassification of opinions from the Foreign Intelligence Surveillance Court, which approves the surveillance efforts.

Obama's meeting with the board was taking place Friday afternoon, but the White House wasn't planning to allow press coverage. White House spokesman Jay Carney said the meeting would take place in the White House Situation Room "to allow for the discussion of classified matters."

"It's certainly more than a get-to-know-you session," Carney said.

The government has already lifted some of the secrecy surrounding the programs following disclosures earlier this month about their existence by former National Security Agency contractor Edward Snowden. But the legal opinions from the highly secretive court remain private.

The privacy board was created in 2004 but has operated fitfully ever since, given congressional infighting and at times, censorship by government lawyers. The board was dormant during Obama's first term and only became fully functional in May, before the NSA programs became public.

The board's chairman, David Medine, said the five-member group has a "broad range of questions" to ask about the NSA's widespread collection programs. The board was given a classified briefing on the programs last week and plans to release a report eventually with recommendations for the government.
