The ACA may reduce ER visits (slightly) but doesn't affect hospitalizations

2015-03-12
(Press-News.org) WASHINGTON - Two patient groups created by the Affordable Care Act (ACA) - Medicare patients enrolled in federally designated patient-centered medical homes and people under age 26 who are allowed to remain on their parents' health insurance - had slightly fewer emergency department visits than they had before health care reform. However, there was no change in the rate of the most expensive types of emergency visits: those that lead to hospitalization.

One study examined the rate of emergency department visits and hospitalizations for Medicare patients treated by patient-centered medical homes. (Primary care practices can receive special designation as patient-centered medical homes (PCMH) from the National Committee for Quality Assurance.) From 2008 to 2010, outpatient emergency department visits grew more slowly for Medicare patients being treated by PCMH practices than by non-PCMH practices. The rate of growth per 100 PCMH beneficiaries was 13 visits fewer for 2009 and 12 visits fewer for 2010. There was no effect on rates of inpatient hospitalization.

"The concept of 'medical homes' has been around since the 1960s and reviews of their effectiveness in improving health outcomes have been mixed," said lead study author Jesse Pines, MD, MBA, FACEP, at the George Washington University School of Medicine and Health Sciences in Washington D.C. "Our study shows that these models can have a positive effect on patients, as far as limiting outpatient emergency department use, but they don't seem to keep patients from being hospitalized, which is many times more expensive than ER visits. Further evaluation of medical homes is needed, particularly on patients who are most likely to benefit, such as those with multiple health problems, a compromised social situation or both."

Maria Raven, MD, MPH, FACEP of the University of California San Francisco, who wrote the companion editorial, cautions that "health care delivery is rarely simple and studying health care utilization is quite complex. The type of outpatient emergency department use that may be affected by PCMH practices is not a main driver of health care expenditures when compared to inpatient hospital admissions and skilled nursing care."

In a related study, the emergency department visit rate declined by 1.6 per 1,000 people among young adults (age 19 to 25) covered by their parents' private insurance plans. The decrease was concentrated among women, weekday visits, non-emergency conditions and conditions that could be treated outside the emergency department.

"The reductions in ER use among young people were quite specific to less severe conditions that could be handled in a primary care setting, which is not unexpected," said lead study author Yaa Akosa Antwi, PhD, of Indiana University-Purdue University in Indianapolis, Ind. "Overall, the reductions in ER use were modest, which suggests that even when the ACA is fully implemented, population-level changes in emergency department use may also be modest. Future research will be needed to assess the effect of coverage expansions on the broader range of adults who will gain coverage under the ACA in the next several years."

Hurricanes require moisture, the rotation of the earth, and warm ocean temperatures to grow from a mere atmospheric disturbance into a tropical storm. But where do these storm cells originate, and exactly what makes an atmospheric disturbance amp up full throttle? A new study published in Geophysical Research Letters by Tel Aviv University's Prof. Colin Price and his graduate student Naama Reicher of the Department of Geosciences at TAU's Faculty of Exact Sciences finds most hurricanes over the Atlantic that eventually make landfall in North America actually start as ...

Engineers create chameleon-like artificial 'skin' that shifts color on demand

Engineers create chameleon-like artificial skin that shifts color on demand
2015-03-12
WASHINGTON, March 12, 2015--Borrowing a trick from nature, engineers from the University of California at Berkeley have created an incredibly thin, chameleon-like material that can be made to change color -- on demand -- by simply applying a minute amount of force. This new material-of-many-colors offers intriguing possibilities for an entirely new class of display technologies, color-shifting camouflage, and sensors that can detect otherwise imperceptible defects in buildings, bridges, and aircraft. "This is the first time anybody has made a flexible chameleon-like ...

Secret of how plants regulate their vitamin C production revealed

2015-03-12
A QUT scientist has helped unravel the way in which plants regulate their levels of vitamin C, the vitamin essential for preventing iron deficiency anaemia and conditions such as scurvy. Professor Roger Hellens, working with Dr William Laing from New Zealand's Plant and Food Research, has discovered the mechanism plants use to regulate the levels of Vitamin C in each of their cells in response to the environment. "Understanding these mechanisms may help in plant breeding programmes to produce hardier plant crops and improve human health because iron deficiency anaemia ...

Government corruption in South Africa contributes to overfishing

2015-03-12
"When I interviewed inspectors they are surprisingly open about this. They tell me that they get a box of fish or just some money from fishermen in exchange for being allowed to break the rules that apply to protected areas or catches," says Aksel Sundström. Many of South Africa's marine fish stocks are overexploited. At the same time, the government actors that are meant to ensure that fishers abide to rules may be a part of the problem. For example, one anonymous inspector is quoted to say: "A Chinese captain that was arrested last week called someone who arrived ...

Liver-sparing operation associated with higher survival rates in cancer patients

2015-03-12
CHICAGO (March 12, 2015): A surgical approach in which a surgeon removes less than a lobe of the liver in a patient undergoing an operation for liver cancer is associated with lower mortality and complication rates, according to new study results published online as an "article in press" in the Journal of the American College of Surgeons (JACS). The article will appear in print in the April issue of the Journal. Historically, the most common surgical method of treatment for liver cancer was a major hepatectomy in which a lobe (hemi-liver) is removed in order to remove ...

Low breast density in mammography worsens breast cancer prognosis

2015-03-12
Very low mammographic breast density worsens the prognosis of breast cancer, according to a recent study from the University of Eastern Finland. Disease free survivals as well as overall life expectancies were significantly shorter in women with very low-density breasts in comparison to women with high density breast tissue. The lower the breast tissue density, the less fibroglandular tissue there is compared to fat tissue. In the future, these findings may prove significant for the assessment of breast cancer prognosis and treatment planning. The study involved 270 ...

Actresses must be picky about with whom they work to survive in movie industry

2015-03-12
WASHINGTON, DC, March 12, 2015 -- Actresses need to be pickier than men about with whom they work if they want to survive in the movie industry, suggests a new study. "My research indicates that women in the film industry suffer a lack of access to future career opportunities when they tend to work with people who have collaborated frequently in the past," said Mark Lutter, lead author of the study and head of the "Transnational Diffusion of Innovation" Research Group at the Max Planck Institute for the Study of Societies (MPIfG) in Germany. Titled, "Do Women Suffer ...

Sweet nanoparticles target stroke

Sweet nanoparticles target stroke
2015-03-12
Materials resulting from chemical bonding of glucosamine, a type of sugar, with fullerenes, kind of nanoparticles known as buckyballs, might help to reduce cell damage and inflammation occurring after stroke. A team from the Max Planck Institute in Germany has tested this on mice, opening the door to potential new drugs for the cerebrovascular accident. The majority of stroke occurs when the blood vessels that reach the brain are blocked by clots or fatty deposits which decrease the flow of blood towards its cells. It is then that an ischemic attack occurs, a pathology ...
