Topic Suggestion Description

Date submitted: June 25, 2010

Briefly describe a specific question, or set of related questions, about a health care test or treatment that this program should consider.

For patients being evaluated for coronary artery disease, what is the comparative effectiveness of strategies using intravascular diagnostic procedures compared to angiography alone or other strategies in deciding whether a procedure is needed?

For patients having a stent implantation, what is the comparative effectiveness of using intravascular imaging techniques compared to angiography alone or other standard strategies in stent outcomes?

Does your question include a comparison of different health care approaches? (If no, your topic will still be considered.)

yes

If yes, explain the specific technologies, devices, drugs, or interventions you would like to see compared:

Measurements of Fractional Flow Reserve, Optical Coherence Tomography, Intravascular Ultrasound compared to angiography and other standard methods

What patients or group(s) of patients does your question apply to? (Please include specific details such as age range, gender, coexisting diagnoses, and indications for therapy.)

Patients with suspected coronary artery disease

Are there subgroups of patients that your question might apply to? (For example, an ethnic group, stage or severity of a disease.)
Describe the health-related benefits you are interested in. (For example, improvements in patient symptoms or problems from treatment or diagnosis.)

Cardiovascular events

Describe any health-related risks, side effects, or harms that you are concerned about.

Procedure risk

Appropriateness for EHC Program

Does your question include a health care drug, intervention, device, or technology available (or likely to be available) in the U.S.?
Which priority area(s) and population(s) does this topic apply to? (check all that apply)
EHC Priority Conditions (updated in 2008)
  • Cardiovascular disease, including stroke and hypertension
AHRQ Priority Populations
  • Low income groups
  • Minority groups
  • Women
  • Elderly
Federal Health Care Program
  • Medicaid
  • Medicare

Importance

Describe why this topic is important.

~3 millions cardiac catheterizations per year in the US

What specifically motivated you to ask this question? (For example, you are developing a clinical guideline, working with a policy with large uncertainty about the appropriate approach, costly intervention, new research you have read, items in the media you may have seen, a clinical practice dilemma you know of, etc.)

items in the media

Does your question represent uncertainty for clinicians and/or policy-makers? (For example, variations in clinical care, controversy in what constitutes appropriate clinical care, or a policy decision.)

yes

If yes, please explain:

Potential Impact

How will an answer to your research question be used or help inform decisions for you or your group?
Describe the timeframe in which an answer to your question is needed.
Describe any health disparities, inequities, or impact on vulnerable populations your question applies to.
