Interpretation

Printed letters distributed as a series regularly from a trusted source has a modest desirable impact on prescribing to new patients.

Further work needs to be done to determine the sustainability of prescribing changes, and to determine what aspects of printed letters elicit prescribing changes

What policies were implemented?

Outcomes based coverage. Funding of new drugs was based on the best

available evidence. A new drug only became a full benefit if it

represented a therapeutic advantage or a cost advantage over appropriate alternatives.

Page 15: Therapeutics Initiative · 2014. 11. 21. · Therapeutics Initiative, 1994 (10 individuals) Mission: To provide physicians and pharmacists with up-to-date, evidence-based, practical

Examples of drug classes affected by this policy

Non-steroidal anti-inflammatory drugs (Cox-2 selective NSAIDs).

Oral hypoglycemic drugs (glitazones and others). Cholinesterase inhibitors for Alzheimers Disease.

Page 16: Therapeutics Initiative · 2014. 11. 21. · Therapeutics Initiative, 1994 (10 individuals) Mission: To provide physicians and pharmacists with up-to-date, evidence-based, practical

What other policies were implemented?

Reference based pricing of equivalent drugs within a drug class.

Restricted access based on special authority criteria.

Therapeutic substitution

Page 17: Therapeutics Initiative · 2014. 11. 21. · Therapeutics Initiative, 1994 (10 individuals) Mission: To provide physicians and pharmacists with up-to-date, evidence-based, practical

Reference based pricing

January 1, 1997 least expensive ACE inhibitors fully covered (captopril, quinapril, ramipril).

More expensive ACE inhibitors covered up to a maximum of $27 per month (benazepril, cilazapril, enalapril, fosinopril, lisinopril).

Patients on more expensive ACEI could pay the difference or switch.

Reference pricing for ACEI conclusions

18% of patients switched to lower cost alternative. Not associated with changes in physician visits,

hospitalizations or mortality. Cost savings to drug funder of approximately $6

million per year.

How much did BC save on prescription drug costs in 2007?

If BC's drug utilization was the same as the Canadian average in 2007, total spending in our province would have been $701 million higher.

$455 million of this saving was due to BC residents purchasing fewer drugs, while $208 million reflects the savings from choosing lower-cost treatment options.

Why were the policies successful?

The TI did not allow any conflicts of interest. Establishing questions for review was an iterative

process. Drug Assessment Working Group (DAWG) followed

Cochrane methodology. DAWG improved critical appraisal skills and

assessing risk of bias over time.

Page 30: Therapeutics Initiative · 2014. 11. 21. · Therapeutics Initiative, 1994 (10 individuals) Mission: To provide physicians and pharmacists with up-to-date, evidence-based, practical

Why were the policies successful?

Researchers were contracted to independently evaluate the impact on drug utilization and health outcomes.

Ministry of Health personnel remained committed to outcomes based coverage and other policies despite political pressures.

Page 31: Therapeutics Initiative · 2014. 11. 21. · Therapeutics Initiative, 1994 (10 individuals) Mission: To provide physicians and pharmacists with up-to-date, evidence-based, practical

What did the TI team learn?

All drugs with any effect have both benefits and harms. Drugs are less effective than what we thought was true. Drugs are more harmful than what we thought was true. In many instances we were shocked that Health Canada

had approved the drugs for market. In most instances drugs are marketed without knowing

that the benefits outweigh the harms in many if not all the clinical settings where they are used.

What should of happened?

Expansion of the reference based program to new classes of drugs eg. Statins.

Continued development of the international reputation of BC as a drug policy innovator.

Increased funding to the Therapeutics Intiative to increase the expertise and ensure the long-term future.

Page 35: Therapeutics Initiative · 2014. 11. 21. · Therapeutics Initiative, 1994 (10 individuals) Mission: To provide physicians and pharmacists with up-to-date, evidence-based, practical

What Happened?

In October 2007 a Pharmaceutical Task Force was announced by BC Health Minister with the following objectives:

1. Identify and strengthen patient care and choice; 2. Optimize the decision-making process for what

drugs are covered under PharmaCare; 3. Improve the effectiveness of the Common Drug

Review process; 4. Enhance the effectiveness, transparency

and future role of the Therapeutics Initiative.

Academic review of TIhttp://www.pharmacology.ubc.ca/

3 member external panel reviewed the TI over 2 days in October 2008.

Validated the roles and activities of the TI in drug assessment, pharmacoepidemiology and education.

Recommendations: Stable funding must be ensured. The present

funding is inadequate. 3 new permanent University F-slots should

be established.

What has happened?

The TI’s advisory role to the BC Ministry of Health has been severely curtailed.

The TI’s funding from the BC Ministry of Health has been reduced to $550,000 per year for the Therapeutics Letter and Pharmacoepidemiology work.

The University has not created any new positions in response to the Academic Review recommendations.

What has happened?

In November 2009, Don Avison confirmed that he was recently appointed as the Canadian representative on Pfizer’s Global International Advisory Board. He did not respond to an e-mail asking what he will be paid.

Don Avison received a Leadership award from LifeSciences BC for his role as Chair of the Pharmaceutical Task Force.

Page 42: Therapeutics Initiative · 2014. 11. 21. · Therapeutics Initiative, 1994 (10 individuals) Mission: To provide physicians and pharmacists with up-to-date, evidence-based, practical

What has happened?

In the spring of 2012 an investigation into data access is initiated by the BC Ministry of Health.

In June, 2012, TI data access is cut off as a result of the investigation.

In October, 2012, TI funding is suspended by the Ministry as a result of the investigation.

In October, 2013, the Ministry of Health announces that TI funding and data access will be restored.

What is wrong with the prescription drug system?

The elephants (Brand Name drug companies) are too wealthy and powerful.

Recommended reading: “The Corporation: The pathological pursuit of profit and power” by Joel Bakan (UBC Professor).

It is not the fault of the corporations. Governments established the system that got us here

and must bring in regulations to correct it.

Ways to improve the system.

Support present independent groups investigating the benefits and harms of prescription drugs.

New money for new groups and to support networking between groups internationally.

Continue to educate prescribers and patients about the benefits and harms of prescription drugs.
