(Press-News.org) A new study shows how pharmacies might collaborate with physicians and families to reduce asthma-related illness.
The Cincinnati Children's Hospital Medical Center study found that pharmacies in neighborhoods with high rates of asthma-related emergency-room use and hospitalization filled fewer asthma controller medications compared to asthma rescue medications.
Asthma-related illness is particularly common among people living in poverty or with limited access to medical care. Previous studies have shown that disparities in asthma rates are perpetuated by underuse of medications that can prevent asthma attacks and control asthma symptoms. Underuse of controller meds results from under-prescribing by health-care providers, under-availability of these medications at pharmacies and poor adherence to medications among patients.
"As on-the-ground members of the health-care team, community-based pharmacies and pharmacists are well-positioned for an increased role in population health management," says Andrew Beck, MD, a pediatrician at Cincinnati Children's and lead author of the study. "Tracking medication fills could highlight ways in which pharmacies could deliver proactive, as opposed to reactive, asthma care."
The study was published May 4 in the eFirst pages of the journal Pediatrics.
The researchers studied two sets of data that provided information on the same geographic region - Hamilton County in southwest Ohio. One set included children between the ages of 2 and 17 who visited the emergency department or were hospitalized for asthma at Cincinnati Children's between Jan. 31, 2010, and Jan. 30, 2012. The second set was provided by 27 retail Kroger pharmacies in 27 distinct census tracts or neighborhoods. This dataset included all 35,467 asthma medications filled for children in the 2-17 age group during the same time period.
The researchers classified medications as either controller or rescue. They then calculated a dispensing ratio for each pharmacy by dividing all dispensed controller medications by the sum of all controller plus all rescue medications. Census tracts with pharmacies that had a lower ratio had significantly higher utilization rates, even after accounting for their higher rates of poverty and more limited car availability.
Pharmacies located in high utilization census tracts - those with more asthma attacks - were also found to dispense more rescue medications than controller medications throughout the year. The opposite was true for pharmacies in low-utilization, or healthy, census tracts.
"We developed this asthma medication ratio to better understand disparities across our county and to potentially inform allocation of resources to those pharmacies and areas in most need of improvement," says Dr. Beck. "Pharmacies might aggressively provide medication delivery or counseling services, they could flag patients who refill a disproportionate number of rescue medications compared to controllers, or they could more regularly communicate with physicians regarding those patients who do not seem to be responding to current therapy. Our findings also support more active data-sharing between such integral members of the health-care team."

As the realities of legalized marijuana take hold in four states and the District of Columbia, legislators and regulators could learn a lot from the successes -- and failures -- of the tobacco and alcohol industries in keeping their harmful products out of the hands of children and adolescents.
So say three Johns Hopkins Bloomberg School of Public Health researchers in a commentary published May 4 in the journal Pediatrics.
"The early days of marijuana legalization present a unique window of opportunity to create a regulatory environment that minimizes youth access," ...
A group of Cambridge computer scientists have set a new gold standard for openness and reproducibility in research by sharing the more than 200GB of data and 20,000 lines of code behind their latest results - an unprecedented degree of openness in a peer-reviewed publication. The researchers hope that this new gold standard will be adopted by other fields, increasing the reliability of research results, especially for work which is publicly funded.
The researchers are presenting their results at a talk today (4 May) at the 12th USENIX Symposium on Networked Systems Design ...
PHILADELPHIA - Gene therapy for Leber congenital amaurosis (LCA), an inherited disorder that causes loss of night- and day-vision starting in childhood, improved patients' eyesight within weeks of treatment in a clinical trial of 15 children and adults at the Scheie Eye Institute at the Perelman School of Medicine at the University of Pennsylvania. New results involving a subset of patients from the ongoing trial show that these benefits peaked one to three years after treatment and then diminished. The findings are published today in The New England Journal of Medicine.

MEDFORD/SOMERVILLE, Mass. (May 3, 2015) -- A Tufts University study sheds new light on the process by which DNA repair occurs within the cell. In research published in the May 15 edition of the journal Genes & Development and available May 4 online in advance of print, Tufts University biologist Catherine Freudenreich and her co-authors show that expanded repeats of the CAG/CTG trinucleotide (CAG) in yeast shift to the periphery of the cell nucleus for repair. This shift is important for preventing repeat instability and genetic disease.
CAG expansions are significant ...
Young people are aware of the risks of cyberbullying but perceive others as being more at risk than themselves. Young women are more vulnerable to this perception than young men.
This is the finding of a study by Dr Lucy Betts and Sondos Metwally from Nottingham Trent University (NTU) that will be presented as part of the poster presentation session at the British Psychological Society's Annual Conference next week (Thursday 7 May 2015) hosted in Liverpool.
A survey, designed to measure how vulnerable young people felt to cyberbullying and how vulnerable they felt ...
PHOENIX and SAN FRANCISCO -- May 1, 2015 -- Led by the Translational Genomics Research Institute (TGen) and UC San Francisco (UCSF), a comprehensive genetic review of treatment strategies for glioblastoma brain tumors was published today in the Oxford University Press journal Neuro-Oncology.
The study, Towards Precision Medicine in Glioblastoma: The Promise and The Challenges, covers how these highly invasive and almost-always-deadly brain cancers may be treated, reviews the continuing challenges faced by researchers and clinicians, and presents the hope for better treatments ...
Young children with autism spectrum disorder, who also have serious behavioral problems, showed improved behavior when their parents were trained with specific, structured strategies to manage tantrums, aggression, self-injury, and non-compliance.
The findings from this parent training study by Yale and Emory University researchers were published recently in the Journal of the American Medical Association (JAMA).
Autism spectrum disorder (ASD) is a chronic condition beginning in early childhood and defined by impaired social communication and repetitive behavior. ...
Expanding what we know about college students mixing alcohol with energy drinks, investigators from Dartmouth's Norris Cotton Cancer Center found teens aged 15-17 years old who had ever mixed alcohol with energy drinks were four times more likely to meet the criteria for alcohol use disorder than a teen who has tried alcohol but never mixed it with an energy drink. The Dartmouth team, led by James D. Sargent, MD with first author Jennifer A. Emond, MSc, PhD published "Energy drink consumption and the risk of alcohol use disorder among a national sample of adolescents and ...
Procrastination is the thief of time that derails New Year's resolutions and delays saving for college or retirement, but researchers have found a way to collar it.
The trick? Think of the future as now.
"The simplified message that we learned in these studies is if the future doesn't feel imminent, then, even if it's important, people won't start working on their goals," said Daphna Oyserman, lead researcher and co-director of the USC Dornsife Mind and Society Center.
Through a series of scenarios, Oyserman and co-author Neil Lewis Jr. of the University of Michigan ...
Shopping online or in catalogs is great for many reasons: to while away time on a snowy day; to avoid the holiday crush at the local mall; to do ultra-efficient comparison shopping; to enjoy a world of choice at your fingertips. But if you need a pair of shoes for the party tonight? Not so much.
Online and catalog retailers pondering whether to add physical stores to their customers' buying options can look to recent research by marketing professors Koen Pauwels and Scott A. Neslin for valuable insights on the interplay among the various channels.
