Background and study aims.
The potential benefits of new drug treatments and increased medication use have not been fully realized, even though the proportion of health costs due to drug costs continues to rise on a yearly basis. This has created a need to investigate new methods to maximize the benefits of existing and new drug treatments while minimizing costs. This research will build on North American initiatives to implement electronic prescribing and integrated drug management systems to improve safety. The study will assess whether access to detailed comparative information on patient out-of-pocket cost for drugs of equivalent effectiveness at the time of prescribing will reduce the overall cost of medication prescribed for elderly patients. The intervention will target medications commonly used to treat cardiovascular disease, high cholesterol, acid-peptic disease, and common chronic respiratory problems. It will also determine the impact on patient adherence with the targeted prescription medications. The results of this research will help to assess the degree to which evidence-based decision-support systems for chronic disease management can be integrated into drug management systems and produce improvements in quality and outcome of care by primary care physicians.
Who can participate?
Physicians are eligible for inclusion if they are primary care practitioners who treat elderly patients and are participating in part or full-time practices in Quebec City, Montreal, or Boston in the electronic prescribing and integrated electronic medical record projects (MOXXI in Quebec and the Partners Healthcare Longitudinal Medical Record with RxHub in Boston).
Patients will be eligible for inclusion in the study if they are 65 years of age or older, and make one or more visits to an enrolled study physician during follow-up. Only patients who have been prescribed or dispensed one or more of the target medications (i.e. antihypertensives, lipid-lowering drugs, anti-ulcer drugs, and drugs for asthma and COPD) during follow-up will be eligible.
What does the study involve?
A study with 12 months of follow-up will be conducted in 100 primary care clinics, representing 300 physicians and 52,852 of their elderly patients. Clinics, sorted by city, size, and baseline drug costs for elderly patients, will be randomly allocated to receive a) comparative expected patient out-of-pocket expenditure information or b) the integrated drug management/electronic record system alone. Comparative expected patient out-of-pocket expenditure information will be provided for elderly patients receiving drug treatment for cardiovascular disease, hyperlipidemia, acid-peptic disease, and common chronic respiratory problems as drug treatment for these conditions is responsible for 65% of the drug budget and is the fastest growing sector of expenditure.
What are the possible benefits and risks of participating?
This study involves minimal to no risk.
Where is the study run from?
The study is run from Quebec City and Montreal, Quebec, Canada and Boston, MA, USA
When is study starting and how long is it expected to run for?
The study started on January 1st, 2009 and is expected to run until January 1st, 2014
Who is funding the study?
Canadian Institutes of Health Research (CIHR)

| Scientific title | Providing comparative out-of-pocket cost information for prescription drugs through an integrated physician electronic prescribing system: a proof of concept with anti-hypertensive drugs |
| Study objectives | The primary objective is to determine if provision of comparative information on expected out-of-pocket expenditures for anti-hypertensive drugs to physicians at the time of prescribing for uncomplicated hypertension therapy will increase the proportion of patients receiving more cost-effective treatment. The secondary objective is to determine if primary and secondary adherence with anti-hypertensive medication is improved by providing physicians with information needed to reduce out-of-pocket expenditures for anti-hypertensive treatment. As of 14/06/2012, the following changes have been made on the trial record: 1. Anticipated start date has been amended from 01/07/2007 to 26/01/2009. 2. Anticipated end date has been amended from 01/07/2009 to 31/10/2013. Please note that as of 30/04/2013, the following changes have been made to the trial record: 1. The anticipated start date of this trial has been updated from 26/01/2009 to 01/01/2009 2. The anticipated end date of this trial has been updated from 31/10/2013 to 01/01/2014 |
