California Pathologists Balk on Performing CJD Autopsies
By Gary Finch
A recent study that
focused in part on the reluctance of pathologists to perform autopsies on CJD
cases was conducted by the California Emerging Infections Program. The
results, or specifically, the objections of pathologists, should interest
embalmers.
First, some
background. CJD surveillance reports rely on autopsies and neuro-pathologic
evaluation. The 1990–2000 CJD autopsy rates in California were 21%. Most
neurologists were comfortable diagnosing CJD (83%), but few pathologists felt
comfortable diagnosing CJD (35%) or performing an autopsy (29%).
In California, CJD is not
reportable. Since 1999, the California CJD Surveillance Project of the
California Emerging Infections Program, a collaboration of the California
Department of Health Services and the U.S. Centers for Disease Control and
Prevention, has conducted enhanced surveillance for classic and variant CJD.
Currently, pathologic
review of brain tissue obtained by biopsy or autopsy is the only means of
confirming a diagnosis of CJD. Autopsy remains the preferred method for
obtaining tissue, as brain biopsy can result in serious complications (e.g.,
brain hemorrhage or abscess formation) and may not yield adequate amounts of
tissue for analysis. The main role of a brain biopsy is to exclude other
potentially treatable conditions.
This study describes
results from analysis of California mortality data from 1990 through 2000. It
also summarizes responses generated from a statewide survey of neurologists and
pathologists regarding the challenges to diagnosing CJD and variant CJD,
including obtaining an autopsy in suspected cases.
From July to
December 2002, questionnaires regarding experience with diagnosing CJD were
sent to 1,241 California neurologists identified as members of the American Academy of Neurology and 574 pathologists identified as members of the California
Society of Pathologists and the American Association of Neuropathologists.
Most neurologists felt comfortable clinically recognizing classic CJD. The
most commonly cited barrier to obtaining autopsy was family reluctance to give
consent.
A majority of
pathologists were uncomfortable doing an autopsy on a CJD case. Their reasons
ranged from infection control concerns (77%), lack of experience (62%), and
institutional limitations (53%). Less than half of the respondents reported
that confirming the diagnosis of CJD or ruling out variant CJD was an important
reason to pursue an autopsy.
Consensus
opinion of Compliance Plus: If 53% of pathology labs are not fit to handle
CDJ, it stands to reason that nearly 100% of funeral home labs would be
lacking.
Compliance Plus - Opinion on Embalming CJD Cases
We share in the opinion from
the World Health Organization and Centers for Disease Control that posted
remains should not be embalmed.
We further contend that
non-posted cases are also high risk, since the trocar is likely to come into
contact with spinal fluid. We note that the World Health Organization requires
a special autoclave (one that heats about 20 degrees more than a conventional
autoclave) and that to our knowledge, no funeral home has this type of
autoclave.
We are aware of posted
articles appearing in publications from Dodge Chemical Company and Embalmers
Supply Company (ESCO) that promote safe practices for injecting CJD cases. We
take note of all the extra precautions they require, such as covering the
table with plastic to protect it. It is our consensus opinion that any
requirement to cover the prep room table or floor shows that the promoter is
aware that this is a high risk procedure. In our opinion, funeral homes do
not charge enough to cover high risk procedures; embalmers are not paid enough
to engage in them, and they should not.
