Deaths during or after a surgical procedure may be considered
medico-legal and subjected to medico-legal autopsy and inquest. We
define death in medical terms and discuss the implications of the
provisions of the Amended Health Professions Act of 1974 and its recent
amendment. Problems with the old and new definitions of such deaths and
whether the amendment provides additional patient protection for the
patient are considered. We challenge the South African law-makers to
review the all-inclusive terminology in relation to such deaths.
Patients who undergo anaesthesia and medical procedures may die as a result thereof. South African law (1) requires any death considered unnatural (2) to be reported for medico-legal investigation. Unnatural death related to anaesthesia is provided for in the Health Professions Act. (3) In July 2008, a revised version of this statutory obligation came into effect with the proclamation of the Health Professions Amendment Act. (4) We examine the scope and significance of this amendment, and consider its implications for health care providers.
Background and definitions
The repealed law stated that 'the death of a person whilst under the influence of a general anaesthetic or local anaesthetic, or of which the administration of an anaesthetic has been a contributory cause, shall not be deemed to be a death from natural causes as contemplated in the Inquests Act 58 of 1959, or the Births, Marriages and Deaths Registration Act 81 of 1963'. (3)
The amendment provides that 'the death of a person undergoing, or as a result of a procedure of a therapeutic, diagnostic or palliative nature, or of which any aspect of such a procedure has been a contributory cause, shall not be deemed to be a death from natural causes as contemplated in the Inquests Act 58 of 1959, or the Births and Deaths Registration Act 51 of 1992'. (4)
Legislative protection for the anaesthetised patient appeared shortly after the introduction of anaesthesia to facilitate invasive surgical procedures. (5) The drug-induced state of deep unconsciousness and loss of voluntary faculties places patients in a position of vulnerability to hazards of the anaesthesia, and also in a totally compromised state where their lives are subject to the conduct of the health practitioners involved. The expectancy of death following procedures performed under anaesthesia varies widely, from 1 in 133 patients in Togo to 1 in 185 000 in the UK, raising concern about anaesthesia and perioperative safety in developing countries. (6) The peri-operative death rate from inpatient surgery in industrialised countries is between 0.4% and 0.8%, and at least half of all surgical complications may be avoidable. (7) However, deaths caused by the anaesthetic procedure alone account for fewer deaths compared with the surgical procedure itself, with mortality associated with general anaesthesia alone ranging from 0.02% (8) reported in Finland, to 0.06% (9) reported as a global figure.
Issues pertinent to South Africa
The amendment in South African law appears to be related to the requirement for health professionals to recognise the need for greater protection for the vulnerable patient under their authority and care. (10) The wider-ranging provision in section 48 of the Health Professions Amendment Act permits legal inquiry into deaths which may have evaded investigation under the repealed section 56 of the Health Professions Act.
Gordon et al. (11) reported that 94% of anaesthetists in South Africa admitted to a drug administration error. A small but important number of cases led to morbidity or death, thereby expressing the need for greater awareness and reporting mechanisms to identify and manage risks.
Although anaesthesia accounted for few of the maternal deaths in the First Report on Confidential Enquiries into Maternal Deaths in South Africa, it was an important and preventable cause related to substandard care. Almost 67% of maternal deaths reported as being related to the anaesthetic were directly caused by the anaesthetic itself, mainly general anaesthesia, citing human error or professional incompetence as a main element of causation; the prevalent event being failed intubation. (12) Rout decried the lack of autopsy examinations and the poor quality of medical records in this review (of anaesthetic-related maternal deaths), making a strong point about the need to review the term 'anaesthetic death' as it obscures the more substantial and significant cause of such deaths. (12)
Few of these anaesthetic-related maternal deaths were directly linked to the anaesthesia itself, the majority being due to the condition of the patient that necessitated the medical procedure, or a pre-existing co-morbid condition. What is important is that these deaths are eminently preventable. Sadly, all subsequent maternal death reports show a similar trend in the incidence of anaesthetic-related deaths. (13) In tandem with the fifth Millennium Development Goals, (14) which ought to be realised by 2015, maternal health would be greatly advanced by reduction in avoidable maternal deaths associated with anaesthesia. (6)
Legislation as to which deaths that take place under the care of a health professional are reportable for medico-legal investigation differs between countries and even between jurisdictions within some countries. Whether an unnatural death is reported appears to be dependent upon the sophistication of the reporting system, the number of complex surgical procedures managed, and the death investigation system in place. In most countries, deaths that occur within a short time period after a surgical operation or during an invasive procedure, and those that occur under the influence of anaesthesia or to which the administration of an anaesthetic was a contributory cause, become the subject of a medico-legal investigation. (15)
The lack of guidelines for the interpretation of the reporting legislation in South Africa has led to difficulties in applying the law to individual cases. While the original clause in section 56 of the Health Professions Act made deaths related to anaesthesia reportable, there was no specific provision for the reporting of death related to a procedure. Further, reporting was left to the discretion of the practitioner, raising the possibility that some deaths that would otherwise justify medico-legal investigation could be signed off as due to natural causes. Deaths that merit investigation on the basis of possible medical error may therefore be overlooked. The question that must be considered is whether death would have occurred if the medical intervention had not taken place. (15) However, although the law is now amended, the clinician in charge is still responsible for reporting an unnatural death. Additionally, while the repealed legislation generally held the surgeon or anaesthetist as carrying the main burden of liability for a death, the amended rule could have any registered health care professional held so accountable.
Anaesthesia places a person in an unnatural state of unconsciousness that is associated with inherent but preventable risks. In the amendment, all prescripts relating to anaesthesia are now excluded and replaced by one relating to 'procedure'. While attempting to broaden the interpretation beyond 'anaesthetic', it involves the perilous possibility of excluding deaths directly related to the anaesthesia. The vulnerability and protection of the anaesthetised patient is therefore not addressed. It is a significant omission to exclude adverse effects relating to the anaesthetic and other drugs and interventions used in anaesthesia. The amended rule does not provide reassurance that the all-inclusive term 'procedure' would suffice to include deaths related to the anaesthetic for purposes of reporting.
In respect of the period of time after general anaesthesia, death was considered reportable if the patient died before recovering consciousness. (16) In contrast, if death took place even within a few hours of the anaesthetic, but with initial full recovery of consciousness and no causal association with the anaesthetic itself, they would not be regarded as related. However, where an earlier adverse event such as aspiration or airway obstruction may have occurred during anaesthesia, and death occurred due to subsequent related complications in spite of regaining wakefulness, the anaesthetic should be considered contributory. Notwithstanding the duration of time elapsed after the anaesthetic, the death may therefore still be related if a causal association between the anaesthetic and the death can be demonstrated. (16)
International trends show that deaths occurring during or within a short time after either a surgical or invasive procedure or an anaesthetic are generally subjected to medico-legal investigation, notwithstanding the interval between the intervention and death, as long as a plausible causal relationship can be assumed. (17) This seems a rational approach where there are concerns that previous legislation allowed for an unacceptable failure to investigate those deaths that may have been due to negligence, or those that were patently avoidable. The argument (17) that the best term for such deaths should be 'anaesthetic and procedure-related deaths' is compelling.
The suggested terms 'peri-operative' and 'postoperative' death (17) are also vague, and deaths resulting from procedures under anaesthesia but not in an operating room may be excluded from reporting. Surprisingly, South African clinicians often persist in using a '24-hour' rule to decide whether a death following an anaesthetic or surgical procedure is reportable, although no such rule exists in South Africa.
In the early postoperative period where the patient has not recovered from the anaesthetic, many deaths are due to questionable circumstances, and the clinician may be unsure about causation and on reporting. To avoid these possible unnatural deaths being missed, it would be useful if there were a time specification for reporting the death. A time limit of 24 hours would serve this purpose most appropriately, and be in line with global trends and leading international practices. (18) For such patients the clinician would not then be required to exercise a sometimes fallible discretion, as all the early deaths during this 'grey' area would automatically be reported.
The term 'procedure' is not defined in the amended law. It is not clear whether it is inclusive of any procedure regardless of nature or complexity. Hazards during diagnostic procedures include many deaths from interventional radiology procedures. (19) Therapeutic procedures can be the surgery itself, whether major or minimally invasive, and could also relate to drug therapy alone: the Institute of Medicine reported that up to 98 000 preventable deaths a year caused by adverse drug events occurred in health institutions in the USA. (20) On the other hand, deaths from palliative procedures may have escaped scrutiny. Palliative medicine aims to ease pain and provide relief from distress; medical error that negligently shortens the life of a patient, even with terminal disease, is a drop in the standard of care. (21) Any medical interference, including research and experimental interventions, may also be regarded as procedures.
To counter the challenge of a possible increase in the number of reportable deaths and the expected burden to the investigative and medico-legal services, the law should provide in reported cases for the state forensic pathologist or inquest magistrate to have the discretion, in consultation with relevant medical specialist experts as required, to consider whether further medico-legal investigation is required. This evaluation could be done in the form of an official consultation with full documentation accompanying the reporting. A full postmortem examination could be done when it is considered necessary to establish the mechanism and cause of death, and/or where liability on the part of any health provider or institution may be at issue.
The proposal to the Health Professions Council of South Africa is to review the amendment and its terminology. A more precise definition, with broader inclusivity, is needed. It would be prudent for legislators to swiftly review and revise the specific provisions of the recent amendment for best outcome.
To best define health care-related deaths that should be subject to medico-legal investigation, we advocate use of both the terms 'anaesthetic-related' and 'procedure-related', and inclusion of a 24-hour rule in the wording of the legislation. A more precise wording could be a composite of the following essential components:
'The death of a person whilst undergoing a general, regional or local anaesthetic or a medical or surgical procedure, or of which the administration of an anaesthetic or the undertaking of a procedure has been a contributory cause, shall not be deemed to be a death from natural causes, provided that:
i. All deaths within 24 hours of the administration of anaesthetic or performance of a procedure must be the subject of a medicolegal investigation;
ii. A procedure is defined as any medical or surgical procedure, including but not limited to that of a diagnostic, therapeutic or palliative nature, but which, in the opinion of the attending clinician, was associated with material risk of injury or death; and
iii. The nature and extent of the medico-legal investigation must be left to the discretion of a state pathologist or magistrate of the district in which the death occurred.'
Health care providers have a crucial obligation in reporting unnatural deaths of patients under their care. Increased use of medical technology, the ability to treat patients who were previously not considered operable, including the requirement that patients undergoing diagnostic and palliative procedures should be equally considered, increases the risk of error, and therefore calls for increased attentiveness by health practitioners.
The amendment is progressive as it allows for a legal inquiry into a death that would not have occurred if the patient had received a reasonable standard of care during the medical intervention. Further, if negligence is confirmed during an inquest, a patient's next of kin may proceed with a civil claim for material damages suffered due to the untimely death of their family member. Vulnerable patients deserve this protection, particularly where service delivery is poor, with fewer resources and little access to optimal health care. Lack of resources should not allow us to drop our vigilance towards patient protection.
