Communicating risk with relatives in a familial hypercholesterolemia cascade screening program: a summary of the evidence.
BACKGROUND
Familial hypercholesterolemia (FH) is the most common inherited, potentially deadly disease, affecting an estimated 600 000 people in the United States. When FH is undiagnosed and untreated, it is linked with early coronary heart disease in more than 50% of men by age 50 years and 30% of women by age 60 years. Cascade screening is the most cost effective method available to identify family members with this disease; however, cascade screening guidelines do not specify best methods to use when contacting relatives. Therefore, I conducted an exhaustive search of the literature to find the most successful communication methods used in contact tracing and cascade screening.


OBJECTIVE
The purpose of this summary of the evidence was to identify the communication method with greatest impact in having at-risk populations present to a provider for disease screening. These findings will inform clinicians of the most successful methods to implement when cascade screening relatives of known FH patients.


CONCLUSIONS
Most studies support direct contact of relatives via letter, mailed from the provider. Provider-initiated communication more often resulted in relatives being tested when compared with other methods of communication.


CONCLUSIONS
On the basis of the literature, family members of current FH patients will be more likely to present to a provider for cascade screening if they receive written communication from the provider.
