Guidelines for investigating stillbirths: an update of a systematic review.
OBJECTIVE
To identify formal, publicly available guidelines for stillbirth investigation and to identify the most appropriate clinical practice guideline (or component of a guideline) for use in Alberta.


METHODS
A systematic literature search was conducted to identify primary and secondary research studies published between January 1985 and August 2006 and formal, publicly available guidelines on the subject of stillbirth investigation. The Cochrane Library, PubMed, EMBASE, CINAHL, HealthSTAR, Science Citation Index, BIOSIS, and the NHS and CRD databases were searched. The methodological quality of the selected primary research studies was assessed according to specific criteria.


RESULTS
All six of the publicly available clinical practice guidelines selected for this review outlined similar steps in the stillbirth investigation but differed about which tests to include and which components should be core or additional investigations. They agreed on including several elements for routine investigation, such as complete autopsy and detailed examination of the cord and placenta. Of 61 retrieved primary research studies, only seven met the inclusion criteria. No studies compared the value of specific guidelines. Although reviewed evidence highlights the value of fetal autopsy and placental examinations as integral components of stillbirth investigation, the value of other components is still not clear.


CONCLUSIONS
No firm scientific judgement could be made about which clinical practice guideline for stillbirth investigation is the most appropriate or which components are essential. Currently here is no generally accepted reference guideline for stillbirth investigation. Fetal autopsy and placental examination remain important components, assuming the postmortem examination is of high quality. These data may be helpful in counselling parents who are considering whether or not to consent to a postmortem examination.
