(Press-News.org) Boston, MA – Elderly black patients were more likely to be readmitted to the hospital after a prior hospital stay for a heart attack, heart failure, or pneumonia, according to a new study from Harvard School of Public Health (HSPH) researchers. They found that the higher readmission rates were due to disparities related to both race and the hospitals where patients were treated.
"Disparities in health and health care are well-documented in this country, but little was previously known about whether there were disparities in hospital readmissions at the national level," said Karen Joynt, lead author of the study, a research fellow in the department of health policy and management at HSPH, and a physician at Brigham and Women's Hospital (BWH) in Boston. "We found important racial disparities among elderly Americans: Black patients were more likely to be readmitted after being discharged from the hospital, and this was especially true if the discharging hospital cared for a high proportion of minority patients."
The study appears in the February 16, 2011 issue of the Journal of the American Medical Association.
Joynt and her colleagues, E. John Orav, associate professor of biostatistics at HSPH, and senior author Ashish Jha, a physician and associate professor of health policy and management at HSPH, analyzed Medicare data on 30-day readmissions after hospitalization for three conditions: heart attack, heart failure, and pneumonia. They found that black patients had about 13% higher odds of readmission than white patients, regardless of where they received their care. Additionally, patients discharged from hospitals with a high proportion of minority patients had about 23% higher odds of readmission than patients discharged from hospitals with a lower proportion of minorities, regardless of race.
The results were even more striking when those two factors were combined. For example, following a heart attack, black patients discharged from hospitals with a high proportion of minorities had 35% higher odds of readmission than white patients discharged from hospitals with a lower proportion of minorities.
Eliminating health disparities and reducing readmissions are two important goals for policymakers. The Patient Protection and Affordable Care Act calls for financial penalties for hospitals that do a poor job of reducing readmissions. "Our findings suggest that to reduce racial disparities in readmissions, policymakers will need to focus not just on race, but also on where minority patients are receiving their care," said Joynt.

(New York, NY) February 15, 2011 – A new study led by an NYU School of Medicine investigator and published in the February 15, 2011, Advance Online Publication, International Journal of Obesity, challenges the idea that calorie labeling has an effect on the purchasing behavior of teenagers or what parents purchase for their children. Teens appear to notice the calorie information at the same rate as adults, however they respond at a lower rate. The conclusions are similar to a previous study about adult eating behavior by Dr. Brian Elbel, assistant professor and colleagues, ...
Men who start to lose hair at the age of 20 are more likely to develop prostate cancer in later life and might benefit from screening for the disease, according to a new study published online in the cancer journal, Annals of Oncology [1] today.
The French study compared 388 men being treated for prostate cancer with a control group of 281 healthy men and found that those with the disease were twice as likely as the healthy men to have started going bald when they were 20. However, if the men only started to lose their hair when they were 30 or 40, there was no difference ...
Boston, Mass. - Hospital readmissions are increasingly viewed as an indicator of quality of care. If patients receive appropriate discharge care planning and coordinated outpatient follow-up when leaving the hospital, they should transition safely home without the need to return to the hospital. n a retrospective study of inpatient records at 37 free-standing children's hospitals between 2003 and 2008, nearly 20 percent of admissions and one-quarter of inpatient expenditures ($3.4 billion) were accounted for by a small group (2.9 percent) of patients who were readmitted ...
DALLAS – Feb. 15, 2011 – Breast-cancer patient Kristin Wiginton is the first to be treated at UT Southwestern Medical Center with high-beam radiation using the Accuray CyberKnife System, which offers improved cosmetic results, less radiation exposure to surrounding tissue and a shorter treatment period.
Dr. Wiginton is among 45 participants in a UT Southwestern-based clinical trial – the first of its kind in the Southwest – investigating use of the radiation delivery system for breast cancer. Her post-lumpectomy therapy lasted one-third the duration of a typical radiation ...
Chemical releases, suicide bombers, air and subsurface threats: the U.S. Secret Service needs to be prepared to handle these real-life incidents. Training to respond to such incidents, however, has been more theoretical than practical.
Now, with help from the Department of Homeland Security (DHS) Science & Technology Directorate (S&T), the Secret Service is giving training scenarios a high-tech edge: moving from static tabletop models to virtual kiosks with gaming technology and 3D modeling.
For the past 40 years, a miniature model environment called "Tiny Town" ...
Since 1965, the chances of dying early (under 75) are a fifth higher in the north of England than the south, finds a study published on bmj.com today.
An accompanying editorial says the north-south health divide is now at its widest for 40 years and warns that "the north is being decimated at the rate of a major city every decade."
The north-south health divide in England is well documented and has posed a public health challenge - as well as a political and economic challenge - to successive governments. From 2003 to 2010, the UK government had performance targets ...
Depression can be treated effectively with psychotherapy by mental health nurses with minimal training, according to new preliminary research findings.
The study, led by Durham University's Mental Health Research Centre, shows that patients with severe depression can be treated successfully with behavioural activation – a psychotherapy for depression – by non-specialist mental health staff which could potentially lead to considerable cost-savings for the NHS.
Currently, psychotherapies, such as behavioural activation, are delivered by specialist clinicians and therapists. ...
The genome of the Blackleg fungus, which causes the most damaging disease to canola crops worldwide, has been sequenced for the first time by a team of French and Australian scientists.
Professor Barbara Howlett from the School of Botany at the University of Melbourne, who led the Australian research team, said the discovery was a significant step towards controlling the rampant Blackleg disease.
"The 12,500 genes that constitute the genetic blue print for the fungus Leptosphaeria maculans have been identified and now can be mined to discover how this fungus causes ...

UPTON, NY - Scientists hoping to unravel the mystery of proton spin at the Relativistic Heavy Ion Collider (RHIC, http://www.bnl.gov/rhic/), a 2.4-mile-circumference particle accelerator at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, have a new tool at their disposal - the first to directly explore how quarks of different types, or "flavors," contribute to the overall spin of the proton. The technique, described in papers just published by RHIC's STAR and PHENIX collaborations in Physical Review Letters, relies on the measurement of particles called ...
