(Press-News.org) Between 2010 and 2013, data breaches of protected health information reported by HIPAA-covered entities increased and involved approximately 29 million records, with most data breaches resulting from overt criminal activity, according to a study in the April 14 issue of JAMA.
Reports of data breaches have increased during the past decade. Compared with other industries, these breaches are estimated to be the most costly in health care; however, few studies have detailed their characteristics and scope. Vincent Liu, M.D., M.S., of the Kaiser Permanente Division of Research, Oakland, Calif., and colleagues evaluated an online database maintained by the U.S. Department of Health and Human Services describing data breaches of unencrypted protected health information (i.e., individually identifiable information) reported by entities (health plans and clinicians) covered under the Health Insurance Portability and Accountability Act (HIPAA). The researchers included breaches affecting 500 individuals or more reported as occurring from 2010 through 2013, accounting for 82 percent of all reports.
The authors identified 949 breaches affecting 29.1 million records. Six breaches involved more than 1 million records each and the number of reported breaches increased over time (from 214 in 2010 to 265 in 2013). Breaches were reported in every state, the District of Columbia, and Puerto Rico. Five states (California, Texas, Florida, New York, and Illinois) accounted for 34 percent of all breaches. However, when adjusted by population estimates, the states with the highest adjusted number of breaches and affected records varied.
Most breaches occurred via electronic media (67 percent), frequently involving laptop computers or portable electronic devices (33 percent). Most breaches also occurred via theft (58 percent). The combined frequency of breaches resulting from hacking and unauthorized access or disclosure increased during the study period (12 percent in 2010 to 27 percent in 2013). Breaches involved external vendors in 29 percent of reports.
The authors note that the study was limited to breaches that were already recognized, reported, and affecting at least 500 individuals. "Therefore, our study likely underestimated the true number of health care data breaches occurring each year."
"Given the rapid expansion in electronic health record deployment since 2012, as well as the expected increase in cloudbased services provided by vendors supporting predictive analytics, personal health records, health-related sensors, and gene sequencing technology, the frequency and scope of electronic health care data breaches are likely to increase. Strategies to mitigate the risk and effect of these data breaches will be essential to ensure the well-being of patients, clinicians, and health care systems."

Editorial: Keeping Personal Health Information Safe
In an accompanying editorial, David Blumenthal, M.D., M.P.P., of The Commonwealth Fund, New York, and Deven McGraw, J.D., L.L.M., M.P.H., of Manatt Phelps & Phillips LLP, Washington, D.C., write that "if patients have concerns that their digitized personal health information will be compromised, they will resist sharing it via electronic means, thus reducing its value in their own care and its availability for research and performance measurement."
"Concerned patients may also withhold sensitive information about issues such as mental health, substance abuse, human immunodeficiency virus status, and genetic predispositions. Surveys suggest this may already be happening to some degree. Loss of trust in an electronic health information system could seriously undermine efforts to improve health and health care in the United States."
"The stakes associated with the privacy and security of personal health information are huge. Threats to the safety of health care data need much more focused attention than they have received in the past from both public and private stakeholders."

Among patients with atrial fibrillation who filled prescriptions for the anticoagulant dabigatran at Veterans Health Administration sites, there was variability in patient medication adherence across sites, with appropriate patient selection and pharmacist-led monitoring associated with greater adherence to the medication, according to a study in the April 14 issue of JAMA.
Atrial fibrillation is the most common cardiac arrhythmia, affecting more than 3 million patients and necessitating treatment with oral anticoagulation in moderate- to high-risk patients to reduce ...
In a comparison of mechanical prosthetic vs bioprosthetic mitral valves among patients 50 to 69 years of age undergoing mitral valve replacement, there was no significant difference in survival at 15 years, although there were differences in risk of reoperation, bleeding and stroke, according to a study in the April 14 issue of JAMA.
In patients with severe, symptomatic mitral valve disease unsuitable for surgical repair, mitral valve replacement reduces symptoms and improves survival. Bioprosthetic valves (made primarily with tissue) are recommended in patients older ...
PASADENA, Calif., -- Children whose mothers developed gestational diabetes by the 26th week of pregnancy were at increased risk of developing autism later in life, according to a new Kaiser Permanente study published today in the Journal of the American Medical Association.
Researchers examined the electronic health records of more than 322,000 ethnically diverse children born between 28 and 44 weeks at Kaiser Permanente Southern California medical centers between January 1995 and December 2009. They followed the children for an average of 5.5 years and found that those ...
Patients are more likely to take a new type of blood thinner correctly and without missing doses when they are managed by pharmacists, rather than only by doctors or nurses, according to a study co-authored by a researcher at the Stanford University School of Medicine.
Mintu Turakhia, MD, assistant professor of medicine at Stanford, and fellow researchers studied a new treatment for atrial fibrillation, a dangerous heart disorder that increases the risk of stroke and blood clots. The treatment, a drug called dabigatran, is one of a new class of twice-daily oral medications. ...
WASHINGTON D.C., April 14, 2015 - For our modern, technologically-advanced society, in which technology has become the solution to a myriad of challenges, energy is critical not only for growth but also, more importantly, survival. The sun is an abundant and practically infinite source of energy, so researchers around the world are racing to create novel approaches to "harvest" clean energy from the sun or transfer that energy to other sources.
This week in the journal Applied Physics Letters, from AIP Publishing, researchers from the University of Waterloo in Canada ...
Parents who work to instill self-control in their children will see them reap the benefits not only in the short-term but throughout their working life, according to new research in Psychological Science, a journal of the Association for Psychological Science.
The researchers who led the study found that children with high self-control -- who are typically better able to pay attention, persist with difficult tasks, and suppress inappropriate or impulsive behaviors -- are much more likely to find and retain employment as adults, spending 40% less time unemployed than those ...
Instead of shrinking as expected, as part of the normal aging process, the memory center in the brains of seniors maintained their size and, in men, grew modestly after two years in a program that engaged them in meaningful and social activities, new Johns Hopkins Bloomberg School of Public Health-led research suggests.
At the same time, those with larger increases in the brain's volume over two years also saw the greatest improvements on memory tests, showing a direct correlation between brain volume and the reversal of a type of cognitive decline linked to increased ...
WASHINGTON - Gradual and variable change in mental functions that occurs naturally as people age, not as part of a neurological disease such as Alzheimer's disease, is one of the most challenging health issues encountered by older adults, says a new report from the Institute of Medicine. The aging process affects the brain just like any other part of the body. Known as "cognitive aging," the type and rate of change can vary widely among individuals. Some will experience very few, if any, effects, while others may experience changes in their memory, speed of processing ...
COLUMBIA, Mo. - Following the 2012 shooting in Newtown, Connecticut, some in the media and the public speculated a link existed between autism spectrum disorder and violence and, in particular, that violent video games may cause gamers with autism to act violently. Now, a study from the University of Missouri has found evidence to contradict this speculation. It is the first study to test the effects of violent video games on aggression in adults with autism spectrum disorder.
"If violent video games caused adults with autism spectrum disorder to behave aggressively, ...
Messages conveyed on websites may be more persuasive if theses websites are interactive, according to researchers.
In a study, participants who visited an interactive antismoking website were more likely than controls to say that smoking was an unattractive behavior, and more likely to agree with the site's stance against smoking.
"When interface features are perceived as natural, easy to use and intuitive, users will feel more focused and have more fun during browsing," said Jeeyun Oh, assistant professor of communications, Robert Morris University and former Penn ...
