Assessing the functionality and value of introducing Death Investigators into forensic pathology service in South Africa

Abstract

In modern society the medico-legal investigation of death is a prerequisite for the administration of justice and for the betterment of public health. These investigations require a high level of skill, professionalism and ethics and have far reaching effects. South Africa’s high level of unnatural deaths, combined with limited human and fiscal resources, specifically a scarcity in practicing Forensic Medical Practitioners, a lack of adequate training of Forensic Officers and members of the South African Police Service, discrepancies in available statistics and a lack of accreditation and quality control, to name a few, leave the South African medico-legal system overburdened. Death investigation needs to evolve and improve constantly and improvements in death investigation need to occur across a wide spectrum of parameters. In the United States of America, to combat systemic issues such as those experienced in South Africa, Death Investigators have been introduced in a supportive capacity and as an extension of services rendered by Forensic Medical Practitioners. These investigators, who are not medical practitioners but may have some level of training or vocational experience within the medical or investigative field, attend and help to analyse death scenes, collect relevant ante-mortem data, assist during autopsies, expedite special investigations, liaise with other stakeholders and provide testimony if warranted. Multiple benefits are associated with the introduction of these death investigators, with the collection of relevant (pre-autopsy) information which will assist and direct the Forensic Medical Practitioner probably being the most pertinent in the context of this research. The aim of this study was to assess the functionality and value of introducing such Death Investigators into forensic pathology service in South Africa. Specifically, this research focused on the nature and scope of information currently being provided to Forensic Medical Practitioners prior to conducting an autopsy and assessed whether the introduction of these investigators would improve the quality of pre-autopsy information. To determine this, participating Forensic Medical Practitioners were asked to evaluate the quality of information currently provided to them prior to conducting an autopsy and to evaluate the quality of information contained in a Death Investigator worksheet that was completed hypothetically for the same case, as an example of the type of information that would be collected by a Death Investigator. Additionally, the disposition of Forensic Medical Practitioners and external stakeholders to the proposed introduction of Death Investigators was assessed through a questionnaire process. Findings of this research showed that there is a significant deficit in the quality of pre-autopsy information being provided to Forensic Medical Practitioners at present. The current pre-autopsy information received an average information quality score of 21.4%. However, the Death Investigator worksheets received and average information quality score of 84.9% representing a marked improvement. Forensic Medical Practitioners had a favourable disposition to the proposed introduction of Death Investigators and agreed that Death Investigators would provide an improved knowledge and understanding of the circumstances and setting of the death, which in turn would , enhance their ability to strategise a post-mortem approach, to request appropriate special investigations and to better interpret their autopsy findings. Overall, the results of this research suggest that the introduction of Death Investigators would add value, specifically by improving the gathering of appropriate information and would be welcomed by Forensic Medical Practitioners. While this research was conducted in Pretoria, it was done on the premise that the poor-quality pre-autopsy information experienced in Pretoria, is probably, to a greater or lesser extent experienced in other medico-legal laboratories in South Africa. It is recommended, that a multi-centre audit of pre-autopsy information quality is undertaken to verify the results found at the Pretoria Medico-legal Laboratory. Furthermore, to facilitate the introduction of Death Investigators as a new professional category, it is recommended that a working group be convened to further interrogate the added-value potential of this introduction as well as to determine prerequisite educational requirements and acceptable recognised prior learning, and to develop guidelines and scope of practice documents. It is also recommended that should this introduction come to fruition, provision be made to accommodate such Death Investigators on a professional board affiliated with the Health Professions Council of South Africa, to guide training and qualification requirements, advise on best practice and professional standards against which Death Investigators can be held accountable.
