(Press-News.org) Surgical house staff and attending physicians who are reminded about the charges for ordering daily blood drawing for routine blood work appear to reduce the amount of routine blood tests ordered and the charges for these laboratory tests, according to a report in the May issue of Archives of Surgery, one of the JAMA/Archives journals.
"The use of laboratory tests has been rapidly increasing over the past few decades to the point where phlebotomy is a substantial proportion of hospital expenditure, and much of it is unwarranted," state the authors. As background, they note that some institutions have modified computer systems to limit the opportunity for clinicians to order redundant tests. They also point to other studies associating these practices with cost savings and no adverse effects on readmission rates, transfer to the intensive care unit, length of stay, diagnoses, or mortality.
Elizabeth A. Stuebing, M.D., M.P.H., of the University of Miami , and Thomas J. Miner, M.D., from Brown University in Providence , R.I. , conducted a study at a Rhode Island Hospital . For nonintensive care unit patients among three general surgical services, the authors obtained daily phlebotomy data, as well as associated charges for these tests, and calculated the amount spent on blood draws and laboratory tests per patient and as a whole. The researchers then made a weekly announcement, for 11 weeks, to surgical house staff and attending physicians about total charges as well as charges per patient per day averaged over the previous week.
The baseline per-patient daily charges were calculated as $147.73, for an initial total of $36,875 charged per week for routine laboratory tests, including blood counts and chemistry panels. During the intervention, the lowest per-patient daily phlebotomy charge was $108.11, a decrease of 27 percent from baseline, and the lowest overall weekly charge was $25,311. At the end of the 11-week study period, the researchers calculated that $54,967 had been saved. The only two weeks in which charges increased to a great extent from the prior week were the same times in which interns rotated in and out of the unit.
The authors reported that the intervention was successful and the costs of implementing it were negligible. "We focused on simply providing the economic implications of wasteful ordering habits, specifically regarding phlebotomy," they write. "This study successfully showed that even without technical and time-consuming interventions, test ordering behavior can be greatly reduced by making health care providers aware of costs."

Commentary: Is That Laboratory Test Necessary?
In a related commentary, A. Benedict Cosimi, M.D., from Massachusetts General Hospital in Boston, writes, "Stuebing and Miner are to be commended for attempting to reduce the volume of unnecessary phlebotomy orders on their surgical units by increasing the cost consciousness of the caregivers." Cosimi commends Stuebing and Miner for offering "convincing evidence that cost consciousness can provide a potent weapon for reducing some of the wasteful medical spending that contributes to our overall health care bill, which currently is twice as much per person as that of most industrialized countries."

Objective evidence of skin infestation lacking in patients with diagnosis of delusional infestation
2011-05-17
Among patients with a diagnosis of delusional skin infestation, neither biopsies nor patient-provided specimens provided objective evidence of skin infestation, according to a report posted online today that will be published in the September issue of Archives of Dermatology, one of the JAMA/Archives journals.
Delusional infestation is a condition in which patients steadfastly yet mistakenly believe that pathogens are infesting their skin. Sometimes, patients believe their skin is literally crawling with bugs, worms, or germs, which is also known as "delusions of parasitosis." ...
Propranolol associated with improvement in size and color of head and neck hemangiomas in children
2011-05-17
The beta-blocker propranolol appears to be associated with reducing the size and color of hemangiomas of the head and neck in a pediatric population, according to a report in the May issue of Archives of Otolaryngology–Head and Neck Surgery, one of the JAMA/Archives journals.
According to background information in the article, hemangiomas are tumors that appear by the age of 2 months, affecting up to 10 percent of full-term white infants. These lesions can be benign, or can affect functions such as the ability to see or on occasion can be life-threatening if they occur ...
Nasal steroid spray may not help resolve dysfunction of the ear's eustachian tubes
2011-05-17
For patients with eustachian tube dysfunction (ETD), steroids administered by a nasal spray may be ineffective, according to a report in the May issue of Archives of Otolaryngology–Head and Neck Surgery, one of the JAMA/Archives journals.
The eustachian tubes connect the middle ear, the upper part of the throat and the ends of the nasal passages. Eustachian tube dysfunction may contribute to fluid collection in the middle ear (otitis media with effusion, or OME) or negative middle ear pressure (NMEP). Presently there is no gold-standard single treatment for this condition, ...
Employees don't always share well with others, says new paper exposing 'knowledge hiding'
2011-05-17
Toronto - Why isn't knowledge transfer happening more often in companies spending money on it?
Maybe it's because their staff don't always want to share.
"We've had years of research in organizations about the benefits of knowledge-sharing but an important issue is the fact that people don't necessarily want to share their knowledge," says David Zweig, a professor of organizational behaviour and human resources management at the University of Toronto's Rotman School of Management and the University of Toronto at Scarborough.
His paper, co-authored with Catherine ...

Transferring a segment of muscle from the thigh appears to help restore the ability to smile in children with facial paralysis just as it does in adults, according to a report in the May issue of Archives of Facial Plastic Surgery, one of the JAMA/Archives journals. The article is part of a theme issue focusing on facial plastic surgery in the pediatric population.
Facial paralysis often disrupts the ability to smile. In pediatric patients, this can be especially problematic, according to background information in the article. Surgery to repair the affected area may generate ...
Freedom in the swamp: Unearthing the secret history of the Great Dismal Swamp
2011-05-17
It's the year 1800. You're a slave in southeast Virginia. You manage to escape. Your freedom is only going to last as long as you can hide. Where do you go?
Would you believe the Great Dismal Swamp? According to Dan Sayers, assistant professor of anthropology and an historical archaeologist at American University, that's exactly where you could have gone for immediate sanctuary.
"There are interesting parallels. What was once more of a human refuge is now a natural refuge," said Sayers of the swamp, which officially became the Great Dismal Swamp National Wildlife ...
Abcc10 may be effective in extending the effectiveness of anticancer drugs
2011-05-17
PHILADELPHIA, PA (May 16, 2011)––Today's anticancer drugs often work wonders against malignancies, but sometimes tumors become resistant to the effects of such drugs, and treatment fails. Medical researchers would like to find ways of counteracting such resistance, but first they must understand why and how it happens. New findings by Fox Chase Cancer Center researchers identify one protein, Abcc10 (also known as Mrp7), as being intimately involved in resistance to certain drugs used to treat breast, ovarian, lung, and other cancers. The results suggest that blunting the ...
Duke-NUS researchers identify new cell that attacks dengue virus
2011-05-17
Durham, N.C., and Singapore – Mast cells, which can help the body respond to bacteria and pathogens, also apparently sound the alarm around viruses delivered by a mosquito bite, according to researchers at Duke-NUS Graduate Medical School in Singapore.
"It appears the mast cells are activated and call immune system cells to the skin where they clear infection, which limits the spread of infection in the host," said lead researcher Ashley St. John, a Research Fellow with Duke-NUS in the Program in Emerging Infectious Diseases, and the Duke Department of Pathology in Durham, ...
Will global climate change enhance boreal forest growth?
2011-05-17
With an increasingly warmer climate, there is a trend for springs to arrive earlier and summers to be hotter. Since spring and summer are the prime growing seasons for plants—when flowers bloom and trees increase in girth and height—do these climate changes mean greater seasonal growth for plants? This is a critical question for forest management, especially in the boreal region—an area particularly sensitive to the effects of climate change.
Dr. Jian-Guo Huang, currently a post-doc at the University of Alberta, and colleagues from the University of Quebec at Montreal ...
Detecting lung cancer early
2011-05-17
Scientists working with Professor Dr. Joachim L. Schultze have identified over 480 molecules whose concentration in the blood changes when a person develops lung cancer. These molecules are present in the blood cells either in increased or decreased quantities. "In lung cancer patients, typical patterns which can be detected with a measuring program thus emerge", explains Prof. Schultze. The molecules are nucleic acids which form in the body when certain genes are transcribed.
The changes in the blood also occur if the tumor is still in a very early stage. In lung cancer, ...
