E-health drug data saves $436M: study

Canada is seeing e-health gains in the area of medication, with an estimated $436 million in cost savings and efficiencies this year, a report released Wednesday says.

Drug information systems, which are hooked up now mainly in the western provinces and Prince Edward Island and to a lesser extent elsewhere, allow pharmacists and health-care providers to electronically access records of a patient's prescription medications.

And they provide a full and accurate medication history so that potential drug interactions or allergies can be caught before they happen.

The $436-million tally and report were compiled by Deloitte for Canada Health Infoway, a federally funded organization that was founded in 2001 and charged with helping provinces and territories to adopt electronic health-record projects.

"We expect that number to increase over time as drug information systems are more widely used in the country, and we get more experienced with their use," said Jennifer Zelmer, senior vice-president of clinical adoption and innovation at Infoway.

Forecast: $1B in savings

It's the first such report to assess the estimated gains for this level Generation 2 of drug information systems.

The report projects that once Generation 2 systems are more widely implemented across the country, and people are more experienced in using them, they will generate about $1 billion a year in benefits.

But Zelmer couldn't say when that would be.

"We're certainly moving as fast as we can."

Saskatchewan, Manitoba and Prince Edward Island are at 100 per cent in terms of implementing Generation 2 drug information systems, while British Columbia and Alberta are about 90 per cent operational, she said.

In Ontario, hospital emergency programs have access to medication profiles for seniors and others who have drugs provided through government programs.

About half the hospital emergency rooms in Canada are currently linked to these drug information systems, Zelmer noted.

"If you come in and you're unconscious, or for whatever other reason can't provide information about the medications you're on, authorized health-care providers can still understand your medication profile, and know whether it's safe to prescribe any medication for you or not," she said.

Higher productivity

The report offered a breakdown of where the benefits and productivity gains were realized.

It attributes 21 per cent of total benefits to better compliance, because the computerized records helped pharmacists work with patients so that medications were more likely to be taken as prescribed.

Another 32 per cent of benefits were related to increased pharmacist and prescriber productivity, because fewer phone calls were needed to check prescriptions.

Reduced adverse drug reactions accounted for 20 per cent of the financial benefit, and reduced medication abuse for 16 per cent. Another 10 per cent was in the area of improved drug cost management.

The findings are a result of a national survey of 750 pharmacists, benefit evaluation studies completed in several provinces, a study of British Columbia's experience with identification and reduction of adverse drug events and P.E.I.'s study of how many more prescriptions can be processed with the electronic records, compared to in the past.
