Bringing Science to Practice: Therapy Underutilization and Compliance in CV disease - The Aspirin Perspective

Aspirin underuse, poor compliance and cessation

Giuseppe Biondi-Zoccai, MDSapienza University of Rome, Latina, Italy

Melbourne, May 6, 2014 – 16:00 to 19:00 - Room M14, Crown Promenade

Goals of the Roundtable

• Prevalence of non-adherence to Aspirin• Consequences of

non-compliance/discontinuation to Aspirin• Issues surrounding non-compliance to Aspirin• Tools and programs to improve compliance to

Aspirin

Too old to be good?

Too good to be true?

Do we still need Aspirin?

What are the facts?

Goals of the Presentation

• Underutilisation and poor adherence in secondary prevention of CVD

• Physician and patient perceptions about Aspirin

• Impact of Aspirin discontinuation (including inconsistent use and temporary discontinuation)

Updated terminology• Cessation: any ceasing or discontinuance• Compliance: accuracy with which a patient follows an

agreed treatment plan• Discontinuation: physician-supervised withdrawal as

perceived as no longer needed• Disruption: cessation due to non-compliance or bleeding

(brief: 1-5 days; temporary: 6-30 days; permanent: >30 days)

• Interruption: physician-supervised temporary discontinuation for surgery lasting <15 days

• Underuse: act of using (or prescribing) less than expected

Avoiding discontinuation is also cheaper


Take home messages• Differentiating between type, reason, setting and

timing of underuse and discontinuation of Aspirin is crucial

• Inadequate physician-patient communication and lack of awareness of underlying cardiovascular risk and benefits are the key reasons for Aspirin underuse and discontinuation

• Underuse and discontinuation are clearly detrimental for patients, especially early after an acute cardiovascular event or procedure, but even later on

ASPREE

• ASPREE is a randomised, double-blind placebo trial of 5-year low-dose (100mg) aspirin for 5 years

• It involves both males and females, 70 years and older • The study is recruiting 19,000 healthy participants through

regional centres (both in urban and rural locations throughout Australia and the United States)

• The trial has a number of sub-studies, which investigate the effect of aspirin on specific diseases: Biobank, ENVIS-ion, ALSOP, SNORE-ASA, ASPREE-AMD, ASPREE-Knee, and ASPREE-NEURO

• Results are expected for 2018

Aspirin: a measure of quality of care?

Quality of health care according to the US Institute of Medicine:

degree to which health services for individuals and populations increase the likelihood of desired health outcomes and are consistent with professional knowledge

Aspirin discontinuation: a hot topic

Means to improve compliance in Asia-Pacific

• Perceived as effective by most physicians:1. Material demonstrating the lifelong benefits of

Aspirin2. Material demonstrating the immediate effects of

Aspirin3. Shared patient-physician decision-making4. Suitable patient information










Avoiding discontinuation is also cheaper
