Adverse drug events costly to health care system: Vancouver Coastal Health-UBC research

25.02.2011
Emergency department physicians call for screening tools

Patients who suffer an adverse medical event arising from the use or misuse of medications are more costly to the health care system than other emergency department (ED) patients, say physicians and research scientists at Vancouver General Hospital and UBC. Their research, the first to examine the health outcomes and cost of patient care for patients presenting to the ED with adverse drug events, is published today in the Annals of Emergency Medicine.

The research team, led by Dr. Corinne Hohl, emergency physician at Vancouver General Hospital and research scientist with the Centre for Clinical Epidemiology and Evaluation at Vancouver Coastal Health and the University of British Columbia, studied the health outcomes of patients who had presented to the emergency department with an adverse drug event and compared them to patients who presented for other reasons.

An adverse drug event is an unwanted and unintended medical event related to the use of medications.

After adjustment for baseline differences between patient groups, researchers found no difference in the mortality rate of the patients they studied, but those presenting with an adverse drug event had a 50% greater risk of spending additional days in hospital, as well as a 20 % higher rate of outpatient health care needs. The team followed 1,000 emergency department patients from Vancouver General Hospital for six months.

This new research builds on a 2008 study, published in the Canadian Medical Journal, which showed more than one in nine emergency department visits are due to medication-related problems.

"What we are finding is that these incidents are common and costly, both in terms of patient health and utilization of health care dollars," says Dr. Corinne Hohl. "We also know that these events are hard for physicians to recognize, and that nearly 70 percent of these incidents are preventable."

In BC alone, hospital emergency departments treat an estimated 210,000 patients each year for adverse drug events. The most common reasons for them are adverse drug reactions or side effects to medication, non adherence, and the wrong or suboptimal use of medication. The research team estimates that the cost of treating these patients is 90% greater than the cost of treating other patients after adjustment for differences in baseline characteristics. The added cost could be as much as $49 million annually.

The research team has been developing screening tools to better assist health care providers in the emergency department in recognizing patients at high risk for adverse drug events, as well as developing an evaluation platform that will help inform prescribing practices for physicians in the community

"We anticipate the development of a screening tool will be able to increase the recognition rate of these adverse drug events from 60 to over 90 percent, and we will be able to treat the patient effectively and rapidly, improving his or her care," says Dr. Hohl.

"Right now we spend a lot of time trying to diagnose what is wrong with the patient, yet often miss the fact that there is a medication-related problem. This means that patients often go home still on a medication which may be causing harm." We are also using the data from this research project to help develop a new drug evaluation platform to inform prescribing practices for physicians in the community. The hope is to prevent many of these adverse events from even taking place."

Funding support for this research is through Vancouver Coastal Health Research Institute, the Michael Smith Foundation for Health Research, and the Department of Surgery at the University of British Columbia.

Im Focus: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
