(Press-News.org) Over the past nine years, Scot H. Simpson, professor in the faculty of Pharmacy and Pharmaceutical Sciences at the University of Alberta, has been studying the role of pharmacists on primary care teams and their impact on the health of patients with Type 2 diabetes.
His most recent study, Pharmacists on primary care teams: Effect on antihypertensive medication management in patients with Type 2 diabetes, published in the May/June issue of the Journal of the American Pharmacists Association, found that having pharmacists on primary care teams had a significant impact on the treatment of blood pressure in patients with Type 2 diabetes.
The study was part of a larger research project published in Diabetes Care in 2011.
The main study, which was a randomized control trial, examined blood pressure control in people with Type 2 diabetes as a measurable, clinically important outcome. Results of the main study showed that the addition of pharmacists to primary care teams produced substantial improvements in the health of patients with Type 2 diabetes.
According to the Canadian Diabetes Association, there are 10 million people in Canada living with diabetes or pre-diabetes, with more than 20 Canadians being newly diagnosed with the disease every hour of every day.
Simpson wanted to delve further and 'pinpoint what specifically pharmacists did to improve patient health.
'Our goal with this sub-study was to deconstruct the interventions being used and understand exactly what it was that the pharmacists did to have a positive effect on patient health,' says Simpson.
Patients in the intervention group were counselled directly by two pharmacists, who worked with the patients' physicians as part of primary care teams at several clinics within Edmonton's Southside Primary Care Network. Control group patients did not see a primary care team pharmacist during the study. At the end of the study, 42 percent of the intervention group patients had at least one change to their blood pressure drugs compared to 26 percent of the control group patients.
'Based on the data, we found that patients who had a change in blood pressure drugs were twice as likely to have an improvement in their blood pressure compared to those who didn't have a change in blood pressure drugs,' says Simpson.
Simpson's findings support the importance of interprofessional health collaboration in treating patients. 'Adding pharmacists to the team to review medications, identify drug-related problems and manage the treatment has a positive effect on blood pressure levels of patients with Type 2 diabetes,' says Simpson.
'The pharmacists involved in the study had very collaborative discussions with the physicians about the patients' medications and proposed drug treatment options,' he says. 'It was from these discussions that the pharmacists were able to suggest alternative medicines or changes in dosage that contributed to lowering the patient's blood pressure.'
In fact, there was one patient who had difficulty in achieving blood pressure target because of reflex tachycardia, which is increased heart rate in response to a lower blood pressure.
'The pharmacist was able to recommend switching from one drug to another and was able to help the patient achieve better blood pressure control without adverse effects,' explains Simpson.
Alberta's pharmacists currently have the broadest scope of practice in North America. While this study was conducted prior to Alberta pharmacists having authorized prescribing authority (APA), the pharmalogical knowledge pharmacists bring to the team is critical, says Simpson.
'Pharmacists use their training to review the patient's medication history and work with physicians to find the best solutions for patients.'

From heat waves to damaged crops to asthma in children, climate change is a major public health concern, argues a Michigan State University researcher in a new study.
Climate change is about more than melting ice caps and images of the Earth on fire, said Sean Valles, assistant professor in Lyman Briggs College and the Department of Philosophy, who believes bioethicists could help reframe current climate change discourse.
"When we talk about climate change, we can't just be talking about money and jobs and polar bears," he said. "Why do we focus on polar bears? Why ...
The National Hurricane Center is keeping a close eye on a developing tropical low pressure area in the south-central Gulf of Mexico. NOAA's GOES-East satellite provided imagery of the system, and an animation was created at NASA showing the development over two days. The system has a high chance for development into a tropical depression.
NOAA's GOES-East satellite sits in a fixed location providing continuous coverage of weather systems in the eastern U.S. and Atlantic Ocean basin. An animation of visible and infrared imagery of the low was created by NASA/NOAA's GOES ...
An international research team has found a way of protecting sensitive catalysts from oxygen-caused damage. In the future, this could facilitate the creation of hydrogen fuel cells with molecular catalysts or with biomolecules such as the hydrogenase enzyme. To date, this could only be accomplished using the rare and expensive precious metal platinum. Together with their French colleagues, researchers from Bochum and Mülheim describe the way in which a hydrogel can serve as a "protective shield" for biomolecules by two articles written in the journals Angewandte Chemie ...
The stress and worry of giving birth prematurely does not adversely affect a mother's parenting behaviour, according to researchers at the University of Warwick.
Preterm children often require special care in the neonatal period including incubator care or assistance with breathing. Previous research has suggested that this stress, separation and an increased tendency for depression may impair a mother's parenting behaviour and adversely affect preterm childrens' long term development.
However, a new paper from the University of Warwick shows that mothers of preterm ...

HOUSTON -- (June 15, 2015) -- A team of biologists from Rice University, the University of Notre Dame and three other schools has discovered that an agricultural pest that began plaguing U.S. apple growers in the 1850s likely did so after undergoing extensive and genome-wide changes in a single generation.
This new result, which appears online this week in Ecology Letters, came from applying the latest tools of genome sequencing and analysis to preserved evidence from experiments carried out at Notre Dame in the 1990s. The research focuses on the fruit fly Rhagoletis ...
DENVER, June 15 -- A new study from the University of Colorado Denver finds that scientists agree that children of same-sex parents experience 'no difference' on a range of social and behavioral outcomes compared to children of heterosexual or single parents.
The study was led by Jimi Adams, an associate professor in the Department of Health and Behavioral Studies at CU Denver College of Liberal Arts and Sciences, and published this month in Social Science Research.
The research comes at a time when the U.S. Supreme Court is determining whether the Constitution requires ...
Bethesda, MD (June 15, 2015) -- Modifying the small white blood cells that protect against disease might help treat immune disorders, according to a study1 published in Cellular and Molecular Gastroenterology and Hepatology, the basic science journal of the American Gastroenterological Association. Specifically, researchers found that modulation of B lymphocyte function may be a means of regulating T lymphocyte function to treat immune-mediated disorders, including inflammatory bowel diseases (IBD).

This news release is available in German. An innovative mechanism that the innate immune system uses to control viral infections has been uncovered by researchers at the University Medical Centers in Mainz and Freiburg. Central to this is the discovery that two different but related elements of the immune system can act together in concert to fight, for example, rotavirus infections. Infection with rotavirus is the most common cause of diarrhea in children around the world. The results of the research have recently been published in the eminent scientific journal Nature ...
