Family history has been integral to family medicine since the
inception of the field. It can provide context to a clinical encounter,
formulate the differential diagnosis for a symptomatic patient, and
guide the delivery of screening and prevention services. Recently there
has been a flurry of activity regarding family history at the national
level.
At a very practical level, a new version of the US Surgeon
General’s My Family Health Portrait (MFHP) was released in 2009. This tool allows patients to collect a
complete family history in the comfort of their home—and improves on
the old tool in that it stores the family history in a structured and
standards-based format. These changes allow compatible electronic
health record (EHR) and personal health record (PHR) systems to import
the data. In the near future, tool users may elect to store their
family history data with third party “Connectivity Partners” (like
Microsoft HealthVault) securely over the Internet. Storing the
information in this manner will allow the individuals and their health
care providers secure access to their family history from any
Internet-connected computer. Access to this data should enable family
physicians to more effectively tailor care to the individual’s health
risks.
Advances in the US Surgeon General’s tool have been facilitated by
something that many family physicians consider mundane—development of
better national standards for family history data in electronic health
record systems. These standards have been adopted by organizations that
drive the development of new capabilities for EHRs and PHRs in the
United States. This is critically important to ensuring that family
history is not lost as family physicians adopt new EHR systems in
preparation for the changes in reimbursement by Centers for Medicare
and Medicaid Services (CMS).
The evidence base supporting the use of family history as a
screening tool in primary care settings has been examined over the last
year, and several STFM members have been active participants. In August
2009 the National Institutes of Health sponsored a State of the Science
conference “Family History and Improving Health” that was designed to
develop research priorities regarding the use of family history as a
screening tool in primary care. The major conclusion of the conference
was that there is a lot of research yet to be done! Very few well-done
and recent research studies have addressed whether using family history
as a screening tool improves health outcomes. Importantly, evidence was
reported at the conference that family history of common serious
conditions obtained from patients is reasonably accurate.
Looking ahead, family history information is likely to be
increasingly used as part of the assessment of risk prior to initiating
screening for common conditions. For example, appropriate use of
several USPSTF guidelines, including those for breast and colorectal
cancer screening, are predicated on health care providers obtaining a
family history and making an accurate determination of a patient’s
risk. In the future, automated health information technology systems
will use patient information, including family history, clinical
characteristics, and lab values (perhaps including genetic risk
markers) to generate more predictive risk estimates and to provide
point-of-care clinical decision support.
We are in an exciting and challenging time in biomedicine where new
and sophisticated technologies for patient care are coming in and out
of style at a blinding pace. Family physicians should be comforted by
the fact that family history is here for the long haul.
