Nurse navigators may aid colon cancer screening follow-up
After positive screening test, they may help Group Health patients get needed diagnosis
2014-11-10
(Press-News.org) SEATTLE--Group Health patients with a positive screening test for colon cancer (a stool test or sigmoidoscopy) tended to be more likely to get the recommended follow-up test, a diagnostic colonoscopy, if nurse navigators contacted them than if they got usual care. This is according to "Results of Nurse Navigator Follow-up After Positive Colorectal Cancer Screening Test: A Randomized Trial" in the November-December Journal of the American Board of Family Medicine, led by Beverly B. Green, MD, MPH, a Group Health physician and a Group Health Research Institute associate investigator.
"The effect didn't reach statistical significance, partly because rates of screening and follow-up were already so high at Group Health--among the highest reported," said Dr. Green, who is also an associate clinical professor at the University of Washington (UW) School of Medicine. The reason follow-up rates were already so high at Group Health is that usual care includes a reminder system that alerts patients' doctors when follow-up testing is needed and hasn't been done.
"Our study showed that combining this systems approach with nurse navigation resulted in colonoscopy follow-up rates exceeding 92 percent," she said, "with 10 percent of that attributable to the nurse navigators."
In 2013 Dr. Green showed that colon cancer screening rates doubled at Group Health with systematic use of electronic health records. The new study is a follow-up trial within that larger Systems of Support to Increase Colorectal Cancer Screening Study (SOS).
Group Health uses the electronic medical record to offer a yearly stool test or a colonoscopy every decade to patients of average risk of cancer of the colon and rectum. When the SOS trial was done, sigmoidoscopy was also an option that patients could choose for screening.
Dr. Green has shown that systematically mailing stool tests to patients each year is a promising way to help prevent disparities in colon cancer screening.
"Screening for colorectal cancer saves lives," Dr. Green said, "but only if people are screened--and if they receive prompt diagnostic testing to follow up on screening tests that suggest that cancer might be present." Around one in three people who have a positive stool test or positive sigmoidoscopy turn out to have either colorectal cancer or an advanced pre-cancer that can be removed during colonoscopy.

In research published today in the Astrophysical Journal, an Australian led team of astronomers has used radio telescopes in Australia and Chile to see inside the remains of a supernova.
The supernova, known as SN1987A, was first seen by observers in the Southern Hemisphere in 1987 when a giant star suddenly exploded at the edge of a nearby dwarf galaxy called the Large Magellanic Cloud.
In the two and a half decades since then the remnant of Supernova 1987A has continued to be a focus for researchers the world over, providing a wealth of information about one of ...

New York | Heidelberg, 10 November 2014 -- Physicists have, for the first time, explored in detail the time evolution of the conductivity, as well as other quantum-level electron transport characteristics, of a graphene device subjected to periodic ultra-short pulses. To date, the majority of graphene studies have considered the dependency of transport properties on the characteristics of the external pulses, such as field strength, period or frequency. The new findings have now been published in EPJ B by Doniyor Babajanov from the Turin Polytechnic University in Tashkent, ...

Philadelphia, November 10, 2014 -- Physician-patient communication about goals of care is a low risk, high value intervention for patients with a life threatening illness, the American College of Physicians (ACP) advises in a paper published in JAMA Internal Medicine.
"Discussions about end-of-life care, especially early in the course of a life-limiting illness, are associated with care more consistent with patient goals and improved patient outcomes, including longer survival rates and better quality of life," said Dr. David Fleming, president, ACP. "This approach is ...

Scientists believe a new treatment, shown to be effective in mice, could halt the growth of tumours in patients with prostate cancer.
Pioneering research, by academics at the Universities of Bristol, Nottingham and the University of the West of England (UWE Bristol), shows that a specific compound can inhibit the activity of a molecule which is key to how tumours form new blood vessels. The vessels are essential for the cancer cells to survive and multiply.
The findings, published today [10 November] in the journal Oncogene, show that targeting a molecule called SRPK1 ...

The sound of monitor alarms in hospitals can save patients' lives, but the frequency with which the monitors go off can also lead to "alarm fatigue," in which caregivers become densensitized to the ubiquitous beeping.
Researchers at Cincinnati Children's Hospital Medical Center have tackled this problem and developed a standardized, team-based approach to reducing cardiac monitor alarms. The process reduced the median number of daily cardiac alarms from 180 to 40, and increased caregiver compliance with the process from 38 percent to 95 percent.
"Cardiac monitors ...

Laundry detergent pods began appearing on U.S. store shelves in early 2010, and people have used them in growing numbers ever since. The small packets can be tossed into a washing machine without ever having to measure out a liquid or powder. The convenience, though, has come with risks for young children.
A new study from researchers at Nationwide Children's Hospital found that from 2012 through 2013, U.S. poison control centers received reports of 17,230 children younger than 6 years of age swallowing, inhaling, or otherwise being exposed to chemicals in laundry detergent ...

When bladder cancer patients are well-informed by their physicians, they acknowledge that tobacco use was likely the cause of their disease. The finding comes from a new study published early online in CANCER, a peer-reviewed journal of the American Cancer Society. Patients with such knowledge may be more motivated to quit smoking, which could help prolong their lives.
At least half of bladder cancer cases diagnosed in the United States are the result of cigarette smoking. Bladder cancer is the second most common tobacco-related malignancy, a fact that is not well known ...

Businesses report that U.S. military veterans make excellent employees, but companies still experience challenges locating and hiring them, according to a new RAND Corporation report.
Studying a group of companies that have made a major commitment to hire veterans, researchers concluded that challenges remain for veterans seeking civilian jobs and employers hoping to hire them, including continuing difficulty understanding the match between military skills and civilian job requirements.
Too often veterans believe their talents apply only in the security or defense ...

The child-mortality gap has narrowed between the poorest and wealthiest households in a majority of more than 50 developing countries, a new study from the Stanford University School of Medicine has found.
This convergence was mostly driven by the fact that child-mortality rates declined the fastest among the poorest families. In the countries where the gap increased, the study identified a common thread: poor governance.
The findings provide important information for making decisions about prioritizing global health investments to effectively promote equity, said ...

JACKSONVILLE, Fla. -- Researchers at Mayo Clinic's campus in Jacksonville say they have identified first steps in the origin of pancreatic cancer and that their findings suggest preventive strategies to explore.
In an online issue of Cancer Discovery, the scientists described the molecular steps necessary for acinar cells in the pancreas -- the cells that release digestive enzymes -- to become precancerous lesions. Some of these lesions can then morph into cancer.
"Pancreatic cancer develops from these lesions, so if we understand how these lesions come about, we may ...
