About Canada What’s relevant for this audience?

• Land area: 3,855,100 sq mi (2nd largest in the world) • Population : 35,158,300,

– Smaller than California (38,041,430) – Quebec (8, 155 300)

• Canadian Health care system = socialized – Universal access – HF patients: lost leader

• Hospital admission: $ $ $ $ • No DRG-diagnosis reimbursement • Devices therapy (ICD-CRT-MCS): more $

– No possibility for the hospital to “Gain Back” some of the lost”

VAD survival (“DT”) compared to Optimal Medical Therapy (IM 3)

Park SJ. AHA Scientific Sessions, November 2010.

So we had to open up the bank somehow to offer this therapy to a growing number of patients.

• The publicly funded cardiology evaluation unit from INESSS conducted a review

of the evidence,

And recommended to the Québec Ministry of Health that use of long-term left ventricular assist devices (LVAD) should be carefully monitored but not limited to bridge-to-transplant patients. March 2012

A Canadian View on Effective Use of VADS: First the data

• In 2013, many Canadian centers joined CANAMACS –Data non available yet

• INESSS: –Retrospective review of hospital data sources of all LVAD-implanted patients (3 centers) → 2010-12. –Variables, definitions & time points as INTERMACS –Major clinical outcomes (death, transplant, recovery) and adverse events were determined during 1-year follow up.

A Canadian View on Effective Use of VADS Conclusion

• Our implant rate is very low – « US benchmark »: 30/100 000 population – Quebec: 0.67/100 000

• In comparison with INTERMACS patients, Québec LVAD patients are younger but sicker and less likely to be DT.

• Despite low volumes, clinical results in Québec hospitals are similar to those reported for INTERMACS. – More adverse events reported with independent data

abstraction compared to self reporting ? • The cost of initial VAD implant in Canada is cheap.

As for DT…

18

• We owe to our patients not to miss the boat – Our volumes will increase, but will remain << USA

• Key for a successfull DT program lies in patients selection.

• Will future policies affect our capacity to offer DT to the Canadian patients? – Some costs are not expected to drop (hospital,…) – The politicians are getter older also…
