Practice-Based Research Card Study Resources

The Card Study is a hallmark method of practice-based research that has been used for more than 30 years.  There are two basic types of card studies - condition specific and prevalence. The basic characteristics of a Card Study are:

  • Observational Study
  • Patient-Level Survey Data
  • Point of Care Data Collection

The Card Study method is a simple, yet effective way to answer clinical questions that come up in everyday practice settings.  The answers to these questions have been used to develop new standards of care for diverse conditions and to establish the prevalence of conditions in primary care and other practice settings.
