The case–case study design is a potentially useful tool for infection preventionists during outbreak or cluster investigations. This column clarifies terminology related to case–case, case–control, and case-case-control study designs. Examples of practical applications of the case–case study design include determining risk factors for health care–onset versus community-onset infections, or antibiotic-resistant versus antibiotic-susceptible infections.
