Type 2 diabetes linked with cognitive impairments, study shows
WASHINGTON A small study conducted by Canadian researchers found factors that may link Type 2 diabetes with such cognitive impairments as dementia.
Older adults with diabetes who also have high blood pressure, walk slowly or lose their balance, or believe they’re in bad health, are more likely to have poorer cognitive functions than those without these problems, according to a new study conducted by researchers at the University of Alberta in Canada and published in the September issue of Neuropsychology
The study of older Canadians — 41 adults with Type 2 diabetes, ages 55 to 81 years, and 458 matched healthy controls (ages 53 to 90 years) — found that systolic blood pressure, a low combination score for gait and balance, and a patient’s own reports of poor health all played a statistically significant role in the relationship between diabetes and cognitive impairment.
“Awareness of the link between diabetes and cognition could help people realize how important it is to manage this disease, and to motivate them to do so,” said co-author Roger Dixon, PhD, of the University of Alberta.
Type 2 diabetes has been found by other researchers to nearly double the risk of dementia and Alzheimer’s disease, said Dixon, who studies how health affects cognition in aging. As diabetes becomes more common, this heightened risk could dramatically hike the number of older people with dementia.
The prevalence of diabetes in the United States for people older than age 60 — according to the National Institute of Diabetes and Digestive and Kidney Diseases — is more than 23%, while Canadian prevalence is nearly 19%, according to the Public Health Agency of Canada.
Active phone prompts spur Rx adherence rates among consumers, CVS reveals
WOONSOCKET, R.I. Consumers are much more likely to adhere to their prescription medication therapy if given “a clear and active choice” in recorded telephone prompts from their pharmacy, new research into patient compliance from CVS Caremark demonstrated.
The company announced Thursday the results of a long-term research project into patient behavior, conducted by its Behavior Change Research Partnership. Those findings, presented at a Pittsburgh Business Group on Health symposium, underline a clear connection between encouraging patients to get their maintenance medications refilled and improved adherence rates.
“Ongoing research into how behavioral economics impacts healthcare choices found that when consumers are presented with a clear and active choice in a voice-recorded message to select automatic prescription refills, rather than a passive default notification, they are twice as likely to choose the automatic option,” CVS said.
CVS established the BCRP in March to study how behavioral economics impacts consumer healthcare decisions. The research group also was created “to help the company better understand why some patients stop taking maintenance medications for chronic illnesses,” the company noted.
The research results were presented by Troyen Brennan, CVS Caremark EVP and chief medical officer. “The preliminary findings show that by making choices clear and by streamlining messages, consumers sign up at twice the rate of those who are passively presented opt-in choices,” Brennan told Pittsburgh business leaders Thursday. “This research will help us develop programs to encourage people to stay on their medications, because nonadherence is costing the healthcare system billions of dollars every year.”
The BCRP research, titled “Active Choice,” is testing options in four communication channels, CVS said. Those channels include interactive Web sign-ins, in-bound customer calls to care centers, automated outbound telephone calls and direct mail.
“The testing shows some options offered to consumers today are overlooked because the choices are not readily transparent,” the company said. “Past industry studies show one-quarter of people receiving prescriptions never fill their first prescriptions, and patients with chronic diseases, such as diabetes and coronary artery disease, adhere to their ongoing medication regimen about half of the time.”
The BCRP panel is led by Punam Anand Keller of the Tuck School of Business at Dartmouth College, George Loewenstein of Carnegie Mellon University and Kevin Volpp of University of Pennsylvania’s Medical School and The Wharton School of Business. The presentation in Pittsburgh continued discussion of BCRP research that was first presented at a Centers for Disease Control and Prevention symposium in Atlanta last month.
SDI: Many Americans have received seasonal flu shot
PLYMOUTH MEETING, Pa. More than 690,000 Americans already have received this season’s flu vaccine from their doctors, according to SDI’s VaccineTrack data through Sept. 4.
VaccineTrack provides syndicated weekly vaccine usage by physicians based on medical office electronic healthcare reimbursement claims data.
The Centers for Disease Control and Prevention recently announced an unprecedented campaign to combat seasonal flu through a universal vaccination strategy. CDC removed many restrictions and currently supports seasonal influenza vaccination for all persons 6 months of age and older based on the recommendation of the Advisory Committee on Immunization Practices, which advises CDC on vaccine issues.
In the 2010-2011 season, vaccine manufacturers are slated to produce more influenza vaccine than ever before. Shipments of influenza vaccine began weeks ahead of most other seasons in anticipation of rapid and wide-ranging vaccine uptake.
“These measures taken by the CDC and vaccine manufacturers facilitate public health efforts to make flu vaccines available to all,” stated Andrew Kress, CEO of SDI.
