Obtaining the family history for common, multifactorial diseases by family physicians. A descriptive systematic review

OBJECTIVE

To summarize the knowledge on the use of comprehensive family history taking for common, multifactorial diseases in primary health care.

DESIGN AND DATA SOURCES

Systematic review of MEDLINE (1966-2008), EMBASE (1986-2008) and Cochrane Library.

METHODS

Search terms reflected 'primary care', 'family history' and 'genetics'. Included were original studies, published in the English language, from a primary care setting, investigating family history taking for multifactorial disorders. Methodological criteria (design, size, response rate) were not used to exclude papers. Out of 116 potentially eligible papers, 27 papers were selected: nine studies on opinions, eight studies on actual practice, seven studies on family history tools, and three studies on the patient perspective. Two authors independently extracted the data, and consequently discussed and summarized them. Given the heterogeneity of the studies, outcomes were presented in a qualitative way.

RESULTS

Among family physicians, the general opinion was that taking a family history is the task of the primary care physician. However, observational studies of consultations and analyses of medical records showed wide variability and low regular updating. There are no family history tools yet, that are sufficiently feasible and reproducible. Patients and doctors may perceive a positive family history differently, which may cause miscommunication.

CONCLUSION

There is a need for research into feasible and high quality tools for detailed family history taking for multifactorial disorders.

The use of the genogram in palliative care

A genogram is a format for drawing a family tree that records information about family members and their relationships over at least three generations. The genogram has been widely promoted as a useful tool for gathering, recording and displaying family information in order to practice family-oriented health care. We present a format for constructing the genogram and to outline the principles underlying its interpretation and application in clinical practice, so as to facilitate its use by physicians, nurses, psychologists, family therapists, and other professionals working with families in palliative care. Finally, the future potential of the genogram as a research and clinical tool in palliative care is discussed.
