Autopsy



Fig. 8.1.
Logical diagram for the sequence of procedures involved for ascertaining medicolegal jurisdiction, validating a consent, identifying the body, and examining the body at autopsy.




 




Trauma



Review circumstances of the case

 



Independently determine that the case is not a case that must be reported to the medicolegal authorities



  • The hospital admitting office may have already made a determination, but this must be checked before beginning. If the patient was admitted to the hospital for treatment of an injury, such as a motor vehicle collision or a fall, then it is likely to be a legal duty to contact the proper authority


  • In general, but not specific to any location, a death must be reported prior to autopsy if the death is a complication of trauma


  • The autopsy physician must first seek a release from the medicolegal authority before entertaining an autopsy in such a case

 


Child Deaths and Specified Medicolegal Cases



Some states have laws mandating that certain deaths be reported to the authorities



  • Commonly encountered statutes include mandatory reporting for child deaths, death of patients referred from extended care facilities, or other special circumstances


  • The autopsy room procedure manual should be a resource for information about specific legal duties for reporting deaths

 




Consent




Legal Requirements for Informed Consent



Determine that the consent for autopsy is proper



  • The legal duty for the pathologist is to prepare a policy and follow a procedure, whereby the consent process fulfills legal requirements


  • Legal requirements for informed consent are somewhat variable among the states. Be knowledgeable about local requirements and review the autopsy room procedure manual instructions


  • Medicolegal cases under the authority of a medical examiner or coroner have consent requirements different from routine hospital cases


  • Routine hospital autopsies require informed consent from the person who is the closest surviving relative of the patient, the legal next-of-kin

 


Legal Next-of-Kin



Observe the requirements for determining that the death need not be reported to the medicolegal authorities

 



Inspect the consent form to determine if the form follows, in good faith, a proper informed consent

 



The person giving consent for autopsy MUST be the legal next-of-kin



  • Local laws will exactly spell out a sequence for the determination of the one person who is the legal next-of-kin with the ultimate sepulchral custodianship of the remains


  • Only that person , and no one else, can sign the autopsy consent


  • Check the hospital admitting record to see if the admitting clerk has filled in the name of a person as the legal next-of-kin at the time that the patient was admitted. If so, this is the person who shall have signed the autopsy consent, and the consent is probably not valid if any other person signed the consent


  • It is, however, quite possible that the admitting clerk was mistaken in completing that information, or that the patient was admitted with that information field blank on the admitting form, so the accuracy of the information must always be checked

 



The priority for next-of-kin is established in law, and it does vary. In some jurisdictions , there can be a “common law spouse,” who may be the legal next-of-kin, while other jurisdictions do not recognize such a status

 



In general, but not in every jurisdiction, the top priority for consenting an autopsy goes to the lawful spouse, and no other person can give consent, even if the spouse is “estranged,” “legally separated,” “incarcerated,” or “of unknown whereabouts”



  • In such a case, no one else can give consent, and the autopsy process must stop without autopsy


  • There is no remedial solution for this problem

 



If a spouse does not exist because the patient was never married, or the spouse has died, or there is a finalized legal divorce, then in most jurisdictions the consent is next obtained from an adult child , if an adult child exists



  • If there is more than one adult child, AND no spouse, there is no legal provision for determining which adult child is the next-of-kin, so sepulchral property right is not clear


  • If there is apparent discord, disagreement, or dysfunction within the family, seek advice from the autopsy service director

 



For a patient without a spouse, and without an adult child, the autopsy consent becomes extremely unclear in many jurisdictions



  • Legal or quasi-legal documents of “power of attorney,” or “medical power of attorney,” or “durable power of attorney,” or “legal guardian” do not ever in any circumstance afford the power to consent an autopsy. These instruments may permit consenting for healthcare of the living patient, but do not apply to any consent process after death. All of these legal appointments and contracts, even the contracts filed with courts, end immediately upon death, and custody and property right revert forthwith back to the legal standard “next-of-kin” scheme. A court-appointed or contracted healthcare representative cannot be used to provide consent for autopsy, even when the guardian represents a state social service agency

 



For pediatric autopsies , the ideal consent is from the mother. If mother is herself a child, it is best for the consent to also be cosigned by the maternal grandmother of the infant. Lesser levels of signature present potential problems, especially if the consent is only signed by the alleged father, where paternity has not been established by any mechanism other than the name on the birth certificate



  • Always check with the autopsy service director before starting an autopsy if the consent is at all questionable

 


Restrictions on Examination




Complete and Partial Autopsy



After confirming the consenting person, check the consent form to see if there are any restrictions placed on the autopsy examination



  • Typically, autopsy consents allow “complete autopsy” or “chest and abdomen”


  • Additional specific limited requests, like “chest only,” “heart only,” or even “liver biopsy only,” do sometimes appear on consents, and such restrictions must be followed exactly

 



A complete autopsy is an unrestricted examination of the body and at least includes the brain and internal organs of the neck, chest, abdomen, and pelvis



  • In some hospitals, or for certain types of diseases, the word “complete” also mandates a complete removal and examination of the spinal cord, such as for Guillain-Barré syndrome , where the diagnosis simply cannot be made unless the dorsal root ganglia of the cord are obtained and submitted for microscopic examination


  • This means checking with an autopsy reference book, such as Ludwig’s Handbook of Autopsy Practice , to determine if there is something special needed for diagnosis


  • Eyes are needed for Von Hippel-Lindau, and many other conditions, and these may not be part of a “routine complete autopsy” at many institutions

 



For autopsies that are restricted by consent to particular organs or body topography (i.e., “chest and abdomen only” or “chest only”), the examination is restricted or limited to the organs within only the consented body cavity

 


Resolving Issues with Autopsy Restrictions



If the autopsy has a medical issue wherein the diagnosis cannot be established due to the limitations of the dissection, it is always best to call the physician who requested the autopsy to see if that physician was aware of the restrictions and aware of the impact that will have on the quality of information obtained by the autopsy

 



In a “chest only” autopsy, there will not be an examination of the liver, even if the liver is visible during the dissection. There will not be an examination of the larynx even though the intrathoracic portion of the trachea is examined

 



The clinicians need to be aware if restrictions prevent answering specific questions about locations of therapeutic devices such as the endotracheal tube or a vena cava filtration device

 


Retention of Organs and Tissues






Retention of organs and tissues after an autopsy , especially the brain, is a controversial practice



  • Historically, retention of the organs has been done by pathologists worldwide for decades, but public outcry, sometimes involving commercial sale of the retained specimens for research or pharmaceutical development, is beginning to limit that practice in some countries and some institutions


  • Retention of tissues and organs by formalin fixation does simplify the process of learning proper autopsy procedure, because the organs are available for future consultation with pathologists. However, not all institutions permit the autopsy physician to retain organs


  • There will be a procedure or consent policy statement concerning retention of organs and tissues, and that policy must be followed. In Great Britain, and in a spreading list of geographic locations, retention of tissues, even the brain, may be forbidden without specific informed consent. In that case, staffing of the autopsy may be compelled to happen directly during the procedure, and the only specimens retained may be the microscopic tissue block specimens

 



Before the autopsy, review the procedure manual or discuss the tissue retention policy with autopsy staff, and comply with the policy. Most pathology residents will be working at institutions where complete retention of organs is the ordinary practice, yet distribution of those retained organs and tissues is strictly regulated

 


Organ and Tissue Donation






Laws pertaining to organ and tissue donation vary across the United States and worldwide

 



The consent to obtain tissues, for medical or commercial donation, even corneas, from the body before or after autopsy, is determined by the tissue bank facility, usually coordinated with the autopsy facility

 



The consent to obtain tissue must include a specific “release of confidential or protected health information” clause, so that the pathologist examining the body can discuss the medical history and results of autopsy tests with the procurement agency

 



Commonly, the organ or tissue facility will contact the pathologist on the day of the autopsy to discuss gross autopsy findings. If this does not happen, there may be circumstances where it is appropriate to try to contact that facility directly. A very common scenario is that there has already been corneal donation, and then the autopsy discloses medically unsuspected and undiagnosed caseating granulomas in the body. That finding may affect utilization of the corneas, and the information, even though preliminary, incomplete, and not confirmed evidence of infection, needs to be assessed by the tissue facility

 



Ultimately, consent for collection of medical, commercial, or research human tissues is to be provided by the tissue bank, not the pathology lab

 



It is always incumbent upon the physician conducting the autopsy to coordinate the autopsy, and access to the body, with any organ or tissue procurement agency once that agency has proper consent



  • The medical suitability of tissues for donation is not determined by the pathologist; it is made by the tissue bank, but the history of risk factors for communicable diseases and metastatic cancer should be made clear in communication with the procurement agency if the pathologist determines that a risk factor MAY exist


  • A common scenario in the autopsy of organ or tissue donors is a finding that discloses the existence of occult tumor or infection, where the existence of that disease was never a part of the patient history. Even before microscopic slide confirmation or culture results, it may be prudent for the pathology resident to communicate that finding immediately by calling the procurement agency, in order to protect a potential graft recipient


  • The medical suitability of tissues is dependent on the overall postmortem interval, as well as factors during life such as infection and cancer metastasis, so timely discussion with the procurement agency, and coordination with that agency, may require scheduling the autopsy to best permit donation


  • Autopsy can be done either before or after donation of skin, bones, corneas, and other tissues. From the standpoint of the procurement agency, they will generally want to go first, but that can change from case to case


  • Any organ or tissue removed for donation will not be examined at autopsy. The whole heart is removed to obtain heart valves for donation, so if heart valves are to be obtained, then there will be no autopsy examination of the heart


  • Postmortem organ and tissue procurement procedures can result in artifacts or changes made to the body, where the autopsy report will need to provide a description of those changes. Donor facilities commonly use nonmedical funeral-industry appliances to repair defects left in the body after removal of corneas and long bones. Removal of skin for donation can leave wide areas of the skin open via split-thickness dermatome incision, and removal of full-thickness skin can leave subcutaneous fat and even skeletal muscle exposed over wide areas of the body

 


Use of Autopsy Tissue for Research



Historically , decades in the past, there were autopsy facilities in America where loose, even verbal, agreements were struck to permit commercial vendors to obtain human pituitaries and human placentas, as well as other body parts, from hospital autopsy rooms, sometimes including fees paid to pathologists for obtaining these tissues. Pituitaries were purchased by pharmaceutical companies to make extracts of human hormones for medical treatment, and placentas were used to extract human chorionic gonadotropin for reagent test kits and fertility drug synthesis. These practices largely or completely disappeared decades ago. Today, specific informed consent, validated and monitored by an institutional review board, may be required before the pathologist gives any autopsy specimen to anyone else outside the immediate reach of patient care for the patient at autopsy. A training institution may have an internal mandate to require specific consent and IRB management for autopsy tissue procurement for human subject research. It is common among pathology resident training facilities to have IRB-approved procurement procedures for research specimens, especially as related to the use of experimental in-dwelling surgical or diagnostic devices where there may exist an approved research protocol to retrieve the device from the patient’s body after death for scientific examination of the device. Every pathology resident should understand that autopsy requests for research specimens are quite routine, but never simple, and there are mechanisms and requirements and procedures that must be monitored by hospitals and academic institutions to sustain ethical use of autopsy specimens for research. Careful understanding of the scope of the autopsy consent is necessary, to stay strictly within the boundaries of that consent when obtaining specimens for research, teaching, or commercial enterprise. A resident leaving training and entering into private practice is expected to know that ethical standards apply to autopsy tissue research

 


Review of The Medical Record






Review and approve the consent

 



Prepare for the autopsy with a review of the hospital chart, as mandated by CAP and Residency Review Committee (RRC) requirements



  • Become completely familiar with the past medical history, prior to the current hospitalization, as this history is always pertinent to the dissection and examination of the organs


  • Read through the medical chart, radiograph reports, and clinical laboratory data

 



Determine if there are any clinical lab tests, such as microbiologic cultures, that might be pending when the patient died



  • Many hospitals direct the clinical laboratory to discontinue pending clinical lab testing upon death of the patient. If there are pending microbiologic cultures, make sure these are not discarded


  • If cultures are pending, call the microbiology lab or the resident on microbiology to ensure that the cultures get completed under the autopsy case number, if they have been deleted from the patient admitting number

 



Determine if the diseases indicated in the clinical history will require any sort of specialized dissections as outlined above under “Restrictions on Examination”

 



If spinal dorsal root ganglia or eyes are going to be needed to establish a diagnosis, then the time to prepare for that dissection is during your review of the medical history



  • You may need special preservation media for cultures or electron microscopy, and you should get those media or containers in the autopsy room before opening the body

 



During The Autopsy



External Examination






Check the hospital identification tags on the body to make sure the correct patient is on the autopsy table

 



If the hospital identification bracelet or tag does not agree with the name and hospital number on the autopsy consent, then do not proceed. Identity must be assured before conducting the internal examination

 



Make a list and take photos of any property or jewelry with or upon the body using nonspecific descriptive language such as yellow or white metal rings on fingers, earrings, and dentures



  • Example: Do not describe “a gold band ring and diamond on the left ring finger”; instead describe “a yellow-colored band ring with clear stone on the left ring finger”

 



Regardless of the limitations from the consent, the entire external body must be examined and documented



  • Record all clothing, jewelry, medical hardware devices, surgical scars, and deformities


  • Undress the entire body, and remove all bandages, but leave all the medical lines and tubes in place

 



Diagrams are useful to locate medical therapeutic devices , even when there is temporary uncertainty about the technical function of the external device. At this preliminary stage in the autopsy, it is entirely possible to have a tube come out through the skin and to be unsure whether that particular tube is intravenous, arterial, or even into a body cavity or drainage site as in Fig. 8.2

Fig. 8.2.
This example illustration of a typical body diagram chart shows nonspecific terms for medical hardware devices often found on the body, where the actual name or internal location of the device will only be revealed during the internal examination, so the description of the device should be generic on the external diagram.




  • Nonspecific terminology like “vascular catheter” and “surgical drainage tube” is far preferable to guessing and potentially misidentifying a peritoneal dialysis catheter as a gastric feeding tube


  • Locations of needle puncture sites should be marked


  • Measure surgical wounds, indicating sutures and staples


  • Describe scars by location and length, but not by surgical type. For example, do not describe a lower abdominal scar as a “hysterectomy scar,” when a patient may have had a Caesarian section and then later had a vaginal hysterectomy


  • Describe all skin injuries, including burns from defibrillator paddles, ecchymoses around needle puncture sites, senile purpura, vascular stasis ulcers, and remarkable skin disease lesions


  • Describe locations of tattoos, but use only brief nonspecific language to describe tattoos. It is preferable to say “multicolor tattoo with wording” than to be graphic in describing a nude image with vulgar inscription. Photos are to be obtained, and those photos are the ultimate reference for tattoo specifics, so the description should be left quite brief


  • Do specifically examine the sacrum for evidence of decubitus ulcer and document by written description the presence OR the absence of such an ulcer

 



Photograph the whole body, after removal of all the clothing, gowns, drapes, and surgical wound bandages
