CHAPTER 43

The different purposes of Coroners' and hospital post mortems

Introduction

There are important differences between the purposes of Coroners' and hospital post mortem examinations. The majority of Coroners' post mortems are carried out to identify the cause of death, while hospital post mortems are intended to investigate the extent of disease(s) and to confirm (or revise) the cause of death that is already known. These different purposes indicate that the scope of a Coroner's post mortem can, and indeed should, be different from a hospital post mortem, particularly when the procedure is undertaken against the wishes of the relatives and/or the deceased.
This investigation has shown that the different purposes of Coroners' post mortems have been overlooked. The practice of a single standard post mortem has blurred the differences in many places.
This chapter describes these differences, and why they should influence the extent of Coroners' post mortems. Subsequent chapters address the attitudes of professional organisations, the public and religious faith groups to Coroners' post mortems where the requirements of the law properly take precedence over the objections of the relatives.

Historical perspective

The first examinations of human bodies after death were undertaken centuries ago and were for what would now be regarded as 'research'. The reason for examining bodies was to identify the internal structures, their relationships and functions. While the position of the major organs was known, many of their functions were not; for example, William Harvey in 1628 discovered that blood was circulated round the body by the heart.
Later, when the anatomy of the internal organs was known, dissections were undertaken for medical teaching purposes.
Investigation into the cause of death
The office of Coroner dates from the Middle Ages, when the role of the Coroner was to find out why a person had died. The post mortem examination was introduced much later as a better way of identifying the cause of sudden or unexplained death.
The Human Tissue Act, 1961
Before 1961, in some hospital deaths relatives had little choice about whether or not a post mortem examination was carried out. There were always some relatives who objected to post mortems for religious or other reasons.
The Human Tissue Act regularised the legal position. Since that date, the consent of relatives has been required for all hospital post mortems. (When a death occurs in hospital and the deceased has no known relatives, this responsibility falls to the hospital authorities.) The relatives can also place limits on the extent of the procedure.
The Human Tissue Act permitted the retention of organs and tissues, providing there was 'no objection' from relatives. This wording, as Chapter 5 noted, is subtly but importantly different from 'with consent', but it carries the implication that steps are required to see if the relatives have objections to organ retention.
How many relatives were actually asked if they had objections to tissue or organ retention during the period 1961 to 1995 will never be known. In those years it was generally assumed that, in consenting to the post mortem, the relatives also had no objection to retention of tissues or organs. The consent forms rarely referred to retention, Chapter 42. It appears from the recollections of relatives, and of those who spoke to them, that the question of retention was infrequently mentioned when relatives were asked to sign the post mortem consent form.
Until media publicity was given to organ and tissue retention it was unusual for the relatives to place restrictions on the extent of the examination, or on the retention of tissues.
The present position is very different. Many relatives are only prepared to agree to a hospital post mortem provided it does not include, for example, the opening of the skull or the retention of any organs or tissues.
Relatives should therefore always be asked about tissue and organ retention to ensure there are no objections.
The main differences between Coroners' and hospital post mortems
The two main differences between Coroners' and hospital post mortems are consent and prior knowledge of the cause of death.
Consent
For the relatives the main difference is that their consent is required for a hospital post mortem but they have no choice in the matter when the Coroner orders a post mortem. For relatives, particularly those with religious objections to post mortems, this difference is stark.
Prior knowledge of the cause of death
For the pathologist the main difference is that in most, but not all, Coroners' post mortems his task is to discover the cause of death. By contrast, in a hospital post mortem the cause will already be known. If this is not so the death should, by definition, have been referred to the Coroner.
For the Coroner identification of the cause of death is the foremost objective, and the decision to order a post mortem examination is for that sole purpose. However, Coroners are not obliged to order a post mortem if there are alternative ways of identifying the cause of death.
The Coroner's responsibilities
Rule 36 of the Coroners Rules deals with 'matters to be ascertained at inquest':
'The proceedings and evidence at an inquest shall be directly solely to ascertaining the following matters, namely:
a) who the deceased was;
b) how, when and where the deceased came by his death;
c) the particulars for the time being required by the Registration Acts to be registered concerning the death'.
For deaths where there is no inquest the Coroner still needs to answer these questions,
and (b) and (c) both relate to the cause of death.
It does not, however, follow that a post mortem examination is the only way to answer these questions. Nor does it follow that if an examination of the body is ordered there must be a 'full post mortem' and that organs and tissues must be retained, though this may be necessary in some cases.
Deaths referred to Coroners
The majority of deaths referred to Coroners are sudden and expected deaths of unknown cause. In the minority, the cause will be known when deaths are reported for other reasons, for example, following an accident or a death during a surgical procedure. In such cases the cause of death is known but the Coroner still needs to satisfy Rule 36 on 'how the deceased came by his death'.
For deaths of unknown cause the Coroner needs to decide whether the cause can be satisfactorily established by reference to the deceased's existing medical condition(s).
In many such cases the probable cause of death becomes clear once the deceased's medical history is available. The Coroner can then decide whether this information is sufficient without resorting to a post mortem. Chapter 44 considers other means through which Coroners could answer the questions posed by Rule 36.
Thus for the Coroner and for relatives the important question is whether a post mortem examination is needed and if it is, the scope of the examination.

Objections by relatives to Coroners' post mortems

A coroner has the authority to order a post mortem examination in any death reported to him. The Coroner's right to insist on an examination is an essential legal safeguard.
As Chapter 42 indicates, however, many pathologists consider a 'full post mortem' should be routinely undertaken. In deciding that a post mortem is necessary, against the wishes of the relatives, the Coroner will need to decide between a full post mortem or restricting the extent of the examination. Many Coroners have indicated their preference for respecting the objections of relatives, provided a limited post mortem satisfactorily identifies the cause of death.
Once the cause of death has been identified, the Coroner's purpose is satisfied and so is Rule 36. It is difficult to see how continuing to a full post mortem can be justified in these circumstances. 'Routine procedure' and 'medical curiosity' are insufficient to justify further disregard of the wishes of the relatives.
The same principle should apply to the retention of organs and tissues from a Coroner's post mortem. These should only be retained when they are relevant to the cause of death.
Chapter 45 illustrates the difficulties that post mortem examinations pose to some religious faith communities. The experience in coronial districts where relatives have been assured the examination will be limited to the minimum necessary has shown that this alone eases the objections of some relatives.

The hospital post mortem

The situation is different in a hospital post mortem. The purpose of the procedure is to examine the extent of the disease that led to death, to look for unexpected features, and to confirm the cause of death. In a proportion of cases the cause(s) will be revised as a result of the examination, but it is rare for a hospital post mortem to discover that death was not due to natural causes.
In a hospital post mortem it has been the practice since 1961 to carry out a full post mortem, including examination of the brain.
Pursuit of knowledge
As medical knowledge advanced, it was found that a better understanding of the direct and indirect causes of death could be learned from post mortem examinations. When deaths occurred in hospital, doctors increasingly wished to learn from post mortem examinations to confirm their diagnosis and to identify any other unrecognised factors that contributed to the cause of death. As a result, in many hospitals post mortem examinations were regularly requested. Before 1961 some hospitals even included consent to a post mortem as a condition of admission.
Many advances in medical knowledge and in the care of patients have come directly from the findings of post mortem examinations. The importance and value of the post mortem and its contribution to better patient care cannot be underestimated, Chapter 46.
Summary
There are different purposes for Coroners' and hospital post mortem examinations. These differences have become blurred by the policy of carrying out a 'full post mortem' in all cases.
The distinction is particularly important when the relatives are opposed to the examination.
Coroners' post mortems are mostly undertaken to establish the cause of death, but once a cause has been found, there is no justification to extend the scope of the examination against the wishes of the relatives.
A more limited post mortem examination may ease the difficulties of some relatives who have religious or other objections to the examination.
In many Coroners' cases, organ retention is not necessary to establish the cause of death. Where retention is necessary, the extent should be limited.
The Human Tissue Act requires the consent of the relatives for a hospital post mortem and lack of objection to tissue and organ retention.
The cause of death will be known before a hospital post mortem. Otherwise the death would have been reported to the Coroner. The purpose is to confirm the cause and to find out if there were any other significant features of the death.
Hospital consent forms have in the past not referred to organ retention but consent for this was assumed when the relatives agreed to the post mortem.
The hospital post mortem was usually a full post mortem, but relatives can place restrictions on the extent of the examination.
Enquiries should always be made to ensure the relatives do not have objections to organ and tissue retention.
The importance of post mortem examinations in contributing to medical knowledge and to improvements in patient care cannot be underestimated.
