The PERFORM-P (Principles of Evidence-based Reporting in FORensic Medicine-Pathology version).

INTRODUCTION: Most findings of forensic pathology examinations are presented as written reports. There are currently no internationally accepted recommendations for writing forensic pathology reports. Existing recommendations are also varied and reflect the differences in the scope and role of forensic medical services and local settings in which they are to be implemented. The legal fact-finder thus faces wide variation in the quality of forensic pathology reports, which poses a threat to the reliability of legal decision-making. To address this issue, the development of the "PERFORM-P (Principles of Evidence-based Reporting in FORensic Medicine-Pathology version)" was undertaken. The goal of the PERFORM-P is to provide common practice recommendations adaptable to local requirements to promote evidence-based practice (EBP) in forensic pathology. METHODS: An international consensus study was conducted in three phases by (1) developing a long-list of items to be considered in the reporting recommendations, (2) conducting a Delphi process (an iterative survey method to transform individual opinions into group consensus) with international forensic pathologists, and (3) designing the PERFORM-P prototype and its accompanying manual. RESULTS: With assistance from 106 forensic pathologists/forensic medical practitioners from 41 countries, the PERFORM-P was developed. The PERFORM-P consists of a list of 61 items to be included in a forensic pathology report, which is accompanied by its Explanation and Elaboration (E&E) document. DISCUSSION: To prepare forensic pathology (postmortem) reports that incorporate principles of evidence-based practice, internationally accepted recommendations might be helpful. The PERFORM-P identifies recommendations for necessary elements to include in a forensic pathology report. PERFORM-P can be applied to a wide range of matters requiring forensic pathological analysis, acceptable to forensic pathologists from a representative selection of jurisdictions and medico-legal systems.

Two halves make a whole: Both first responders and experts are needed for the management and identification of the dead in large disasters.

Catastrophic natural disasters are a regular global issue claiming thousands of lives and having severe and long lasting consequences for communities. Along with the rescue and care of survivors and the provision of basic services, managing the dead in a proper and dignified manner is one of the three pillars of disaster response. Since the 2004 Indian Ocean Tsunami, progress to facilitate better coordination in the management of the dead has been made. Two guidelines contributing to this positive trend are the Interpol DVI Guide, and the "Management of the Dead after Disasters - A Field Manual for First Responders". The former is aimed at forensic specialists and emergency services, the latter at untrained first responders confronted with the management of the dead when specialist forensic services are not available. This paper sets out the complementarity of the two publications, illustrating that ideally, both first responders and experts are needed to properly manage and identify the dead following large disasters.

The risk of HIV, HBV, HCV and HTLV infection among musculoskeletal tissue donors in Australia.

In Australia, there are no current national estimates of the risks of transmission of human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV) or human T-lymphotrophic virus (HTLV) by musculoskeletal tissue transplantation. We determined the prevalence rates of antibodies against HIV (anti-HIV), HCV (anti-HCV) and HTLV (anti-HTLV) and Hepatitis B surface antigen (HBsAg) for 12,415 musculoskeletal tissue donors from three major bone tissue banks across Australia for the period 1993-2004. The prevalence (per 100,000 persons) was 64.44 for anti-HIV, 407.13 for HBsAg, 534.63 for anti-HCV and 121.88 for anti-HTLV. The estimated probability of viremia at the time of donation was 1 in 128,000, 1 in 189,000, 1 in 55,000 and 1 in 118,000, respectively. With the addition of nucleic acid amplification testing (NAT), the probability of donor viremia would be reduced to 1 in 315,000 for HIV, 1 in 385,000 for HBV and 1 in 500,000 for HCV. The prevalence of HIV, HBV, HCV and HTLV although low, are higher among musculoskeletal tissue donors than among first-time blood donors. The risks associated with musculoskeletal donation will be reduced with NAT, though further cost analysis is required prior to its implementation.

Evaluation of management of road trauma survivors with brain injury and neurologic disability in Victoria.

BACKGROUND: Victoria recently established a new trauma care system following the Consultative Committee's findings on frequent preventable deaths after road crash injury. This study investigates the contribution to neurologic disability of preventable deficiencies in health care in survivors of road crashes occurring from 1998 to 1999. METHODS: The emergency and clinical management of 60 road crash survivors with head Abbreviated Injury Scale score > or = 3 and residual neurologic disability were evaluated by analysis and multidisciplinary discussion of their complete prehospital, hospital, and rehabilitation records. RESULTS: The mean number of potentially preventable errors or inadequacies per patient was 19.2 +/- 7.5, with 10.5 +/- 7.2 contributing to neurologic disability. The mean number contributing to neurologic disability was greatest in the emergency room (3.5 +/- 3.2), followed by the intensive care unit (2.2 +/- 2.7) and the prehospital setting (1.8 +/- 2.0). Eighty-four percent of the deficiencies were management errors/inadequacies and 7% were system inadequacies. Fifty-five percent of deficiencies contributed to neurologic disability. In patients with a systolic blood pressure less than 90 mm Hg with hypovolemia consequent to inadequate resuscitation, the frequency of severe neurologic disability was increased almost twofold (p < 0.05). Deficiencies contributing to neurologic disability were significantly less frequent in university teaching hospitals with neurosurgical units. CONCLUSION: Improvement in neurologic outcomes can be achieved through appropriate triage and increased attention to basic principles of trauma and head injury care.

Choking deaths: the role of antipsychotic medication.

BACKGROUND: An increased risk of choking associated with antipsychotic medication has been repeatedly postulated. AIMS: To examine this association in a large number of cases of choking deaths. METHOD: Cases of individuals who had died because of choking were linked with a case register recording contacts with public mental health services. The actual and expected rates of psychiatric disorder and the presence of psychotropic medication in post-mortem blood samples were compared. RESULTS: The 70 people who had choked to death were over 20 times more likely to have been treated previously for schizophrenia. They were also more likely to have had a prior organic psychiatric syndrome. The risk for those receiving thioridazine or lithium was, respectively, 92 times and 30 times greater than expected. Other antipsychotic and psychotropic drugs were not over-represented. CONCLUSIONS: The increased risk of death in people with schizophrenia may be a combination of inherent predispositions and the use of specific antipsychotic drugs. The increased risk of choking in those with organic psychiatric syndromes is consistent with the consequences of compromised neurological competence.

Road traffic fatalities in Victoria, Australia and changes to the trauma care system.

BACKGROUND: The aim was to identify organizational and clinical errors in the management of road traffic fatalities and to use this information to improve Victoria's trauma care system. METHODS: A multidisciplinary committee evaluated the complete ambulance, hospital and autopsy records of 559 consecutive road traffic fatalities, who were alive on arrival of ambulance services, in five substantial time periods between 1992 and 1998. Patients who survived more than 30 days were excluded. Errors or inadequacies in each phase of management, including those contributing to death, were identified and an assessment was made of the potential preventability of death. RESULTS: Findings between 1992 and 1998 were similar. In 1998, 1672 problems were identified in 110 deaths with 1024 (61 per cent) contributing to death. Eight hundred and forty-two (50 per cent) of the total problems occurred in the emergency department. There were frequent problems in initial patient reception and medical consultation, resuscitation, investigation and assessment (especially of the abdomen and head), and in transfer to the operating theatre or to a higher-level hospital. Victoria's combined preventable and potentially preventable death rate has been unchanged between 1992 and 1998 (34-38 per cent). CONCLUSION: The problems identified led to a Ministerial Taskforce on Trauma and Emergency Services in Victoria as a consequence of which a new trauma system is now being implemented.

Issues in child homicides: 11 cases.

For a variety of reasons, child homicides are the most difficult cases for forensic pathologists. For example, the events are usually not witnessed, accidental explanations are offered, often there is more than one carer spanning the period over which the injuries might have occurred and there can be conflicting opinions between the various medical specialities. Eleven cases of fatal child abuse are presented to illustrate and briefly discuss particular difficulties. Reference is also made to interaction with the legal process and parallel difficulties the law has with fatal child abuse.

The preventability of death in road traffic fatalities with head injury in Victoria, Australia. The Consultative Committee on Road Traffic Fatalities.

Since 1992 the Consultative Committee on Road Traffic Fatalities in Victoria (CCRTF) has examined the medical management of patients who died following motor vehicle accidents. Three hundred and fifty-five fatalities with head injury occurring between 1 July, 1992 and 31 December 1997 were assessed by the CCRTF. They represented 79% of the total 449 fatalities examined by the Committee. Following examination of the complete medical records and multidisciplinary discussion, the Committee considered 237 (67%) of the 355 neurotrauma deaths to be non-preventable, 105 (30%) potentially preventable and 13 (4%) preventable. The present analysis excludes the non-preventable deaths in order to focus on preventable factors. Problems identified in the 118 patients pre-hospital included: no intubation; prolonged scene time; and no intravenous access; in 139 emergency room attendances: inappropriate reception including delay in arrival of a consultant, no neurosurgical consultation, no CT scan of the head, inadequate blood gases and oxygen monitoring, inadequate fluid resuscitation, delayed respiratory resuscitation and delayed dispatch to the operating room; in 111 operating room visits: no ICP monitoring, inadequate fluid administration and inappropriate anaesthetic technique; and in 90 intensive care unit admissions: no ICP monitoring. Overall, 1745 individual problems in the various areas of care were identified, of which 1104 (63%) were judged to have contributed to death. Improved delivery and quality of trauma care could reduce the identified problems in emergency services and clinical management. Basic principles of trauma management remain the most important means of reducing morbidity and death following road trauma. The leadership role of the neurosurgeon in neurotrauma care is emphasised.

Consultative Committee on Road Traffic Fatalities: trauma audit methodology.

BACKGROUND: Since 1992 the Consultative Committee on Road Traffic Fatalities in Victoria has identified deficiencies and errors in the management of 559 road traffic fatalities in which the patients were alive on arrival of ambulance services. The Committee also assessed the preventability of deaths. Reproducibility of results using its methodology has been shown to be statistically significant. The Committee's findings and recommendations, the latter made in association with the learned Colleges and specialist Societies, led to the establishment of a Ministerial Taskforce on Trauma and Emergency Services. As a consequence, in 2000, a new trauma care system will be implemented in Victoria. This paper presents a case example demonstrating the Committee's methodology. METHODS: The Committee has two 12 member multidisciplinary evaluative panels. A retrospective evaluation was made of the complete ambulance, hospital and autopsy records of eligible fatalities. The clinical and pathological findings were analysed using a comprehensive data proforma, a narrative summary and the complete records. Resulting multidisciplinary discussion problems were identified and the potential preventability of death was assessed. RESULTS: In the present case example the Committee identified 16 management deficiencies of which 11 were assessed as having contributed to the patient's death; the death, however, was judged to be non-preventable. CONCLUSION: The presentation of this example demonstrating the Committee's methodology may be of assistance to hospital medical staff undertaking their own major trauma audit.

Sudden unexpected death in epilepsy in Victoria.

Sudden unexpected death in epilepsy (SUDEP) refers to sudden unexpected death in patients with epilepsy in whom autopsy fails to reveal an anatomic or toxicological cause of death. The purpose of this study was to examine associated factors and mechanisms relating to SUDEP in Victoria. The study was a retrospective study based on data from questionnaires completed by treating doctors and coronial files including police reports of death, autopsy and toxicology reports. The deaths were of people with epilepsy in Victoria that were referred to the coroner between 1991 and 1997. There were 15,751 coronial autopsies of which 357 had epilepsy and 50 (14%) were SUDEPs. The SUDEP rate was approximately 1 per 3000 epileptics per year. This study suggested the following associations: young age, tonic-clonic seizures, seizure frequency greater than 10/year, duration of epilepsy greater than 10 years, mental retardation, psychiatric disease and alcohol abuse. Antiepileptic drug (AED) compliance was rated by treating doctors as good in 24 cases. One or more postmortem AED drug levels was subtherapeutic in 30 of 50 cases. Only 5 were receiving psychotropic drugs; only 1 of these was receiving more than one of these drugs. A history of recent unusually stressful life event was present in only 4 cases. At least 11 showed evidence of terminal seizure, and the majority of events occurred in sleep. These observations support the hypothesis that seizures are the mechanism of many cases of SUDEP. The associations observed were largely in agreement with previous studies. However, seizure frequency was greater and duration of epilepsy greater than most previous studies. The role of factors such as AED compliance, psychotropic drug prescription and recent unusually stressful life event is less clear. This highlights the need for case-control studies of risk factors for SUDEP.

Deaths due to brain injury among footballers in Victoria, 1968-1999.

OBJECTIVES: To determine the frequency and nature of fatal brain injuries occurring in Australian football. SETTING: State of Victoria, January to July 1999. DESIGN: Retrospective case series of football-related deaths identified from the coronial autopsy records of the Victorian Institute of Forensic Medicine (1990-1999) and newspaper reports (1968-1989). MAIN OUTCOME MEASURES: Coronial autopsy findings and circumstances of injury. RESULTS: 25 deaths associated with Australian football were identified, nine due to brain injury. Coronial findings in the brain-injury deaths were intracranial haemorrhage in eight patients and infarct in the territory of the middle cerebral artery in one. In three of four cases of subarachnoid haemorrhage, vertebral artery trauma was noted. In all but one case, injury occurred as an accidental part of play. CONCLUSIONS: The most common findings in deaths due to brain injury in Australian football were intracranial haemorrhage, including subarachnoid haemorrhage from vertebral artery injury.

Comparison of antiepileptic drug levels in sudden unexpected deaths in epilepsy with deaths from other causes.

PURPOSE: (a) To compare postmortem antiepileptic drug (AED) levels in patients with sudden unexpected death in epilepsy (SUDEP) with those in a control group of subjects with epilepsy. If SUDEP patients more frequently had undetectable or subtherapeutic AED levels, this would suggest that compliance with AED treatment is poorer in this group and that poor compliance is a risk factor for SUDEP. (b) To determine whether a particular AED was detected more commonly in the SUDEP group, suggesting that this AED is associated with a higher risk of SUDEP. METHODS: A retrospective study of coronial cases was performed. Postmortem AED levels in 44 SUDEP cases and 44 control cases were compared. The control group consisted of epileptics who died of causes other than epilepsy, including natural disease (e.g., ischemic heart disease, accidents, and suicide). The AEDs measured included carbamazepine (CBZ), phenytoin, (PHT), valproate (VPA), phenobarbitone (PB), lamotrigine (LTG), clonazepam (CZP), and clobazam (CLB). The number of SUDEP and control cases in which CBZ only was detected were compared, as were the number in which PHT only was detected. RESULTS: Compared with the controls, the SUDEP group showed no difference in the number with no detectable AEDs (13 vs. 11), the number with subtherapeutic AEDs (10 vs. 13), and the number with therapeutic levels (21 in both groups). CBZ only was detected in 11 SUDEPs and 11 controls, and PHT only in five SUDEPs and 10 controls. CONCLUSIONS: Our study suggests the SUDEP group were no less compliant with AED treatment than the control group. This study does not support the hypothesis that poor compliance with AED treatment is a risk factor for SUDEP. There was no evidence that PHT or CBZ is associated with a higher risk of SUDEP.
