|
The Medical Cognition program in the Day Cognition Lab studies how people find, understand, remember, and use medical information. The basic approach has the following characteristics.
Who
Anyone who deals with medical information, especially:
| |
Health Care Professionals --physicians --physicians associates --nurses --nurse practitioners --pharmacists |
Consumers --patients --caregivers |
Others --industry --regulators --legal system |
Medical Information
| General types of medical information include: |
|
--drugs (prescription, over-the-counter) --medical devices --other medical treatments --health information |
| Specific content includes: |
| |
--side effects ("adverse events") --drug interactions --pictograms --medical terminology |
--instructions for use --alternative treatments --medication schedules --health diaries |
| General issues include: |
| |
--cognition in both providers in patients --patient safety --risks (assessment, perception, management) --"fair balance" of benefits vs. risks --medical error --health outcomes --doctor/patient communication --informed consent --electronic medical records (pros and cons) |
Cognitive Accessibility
A key concept in this work is "cognitive accessibility" (Day, 2000), the ease with which people can find, understand, remember, and use medical information in a safe and effective way.
Information Sources
A wide range of existing medical information sources is examined, developed for use by both health care professionals and consumers, including:
| |
-- |
FDA-approved "product labeling" for drugs (also Physicians Desk Reference) |
| -- |
medical device labeling and manuals |
| -- |
patient package inserts (PPI's) |
| -- |
pharmacy leaflets |
| -- |
internet product websites |
| -- |
print and TV ads |
| -- |
informed consent forms |
Methodological Approaches
Basic methodological approaches include:
| 1) |
Information Analysis |
|
|
Evaluate the cognitive accessibility of information in existing information sources. Develop quantitative methods (e.g., for assessing "fair balance" of benefits vs. risks). |
| 2) |
Document Design |
|
|
Design/redesign materials to enhance their cognitive accessibility. |
| 3) |
Laboratory Experiments |
|
|
Test the effects of alternative displays of medical information on cognition and behavior using carefully-controlled laboratory methods. |
| 4) |
Real-World Experiments |
|
|
Test the effects of alternative medical displays on cognition, behavior, and health outcomes in everyday settings (including hospitals, clinics, and self care). |
Goals
| 1) |
To understand why medical information can be hard to understand, remember, and use |
| 2) |
To enhance the cognitive accessibility of medical information |
| 3) |
To enable people to use medical information in a safe and effective manner |
| 4) |
To reduce medical error (by both professionals and patients) |
| 5) |
To understand how cognitive processes operate in real-world situations |
| 6) |
To re-evaluate cognitive theories generated in the laboratory, based on findings from everyday cognition research in medical settings |
