Audit in forensic pathology

Autopsy numbers in Australian hospitals have declined markedly during the past decade despite evidence of a relatively static rate of demonstrable clinical misdiagnosis during this time. The reason for this decrease in autopsy numbers is multifactorial and may include a general lack of clinical and pathologic interest in the autopsy with a possible decline in autopsy standard, a lack of clinicopathologic correlation after autopsies, and an increased emphasis on surgical biopsy reporting within hospital pathology departments. Although forensic autopsies are currently maintaining their numbers, it is incumbent on forensic pathologists to demonstrate the wealth of important information a carefully performed postmortem examination can reveal. To this end, the Pathology Division of the Victorian Institute of Forensic Medicine has instituted a program of minimum standards in varied types of coroner cases and commenced a system of internal and external audit. The minimum standard for a routine, sudden, presumed natural death is presented and the audit system is discussed.     

Pulmonary surfactant-associated protein A levels in cadaveric sera with reference to the cause of death

Pulmonary surfactant-associated protein A (SP-A) is an exclusively lung specific protein, and is considered to leak into the blood stream in alveolar septal damage. In this study we examined the serum SP-A level in forensic autopsy materials using an enzyme immunoassay with monoclonal antibodies to assess the postmortem level in relation to the cause and mode of death. Although a gradual postmortem degradation should be taken into consideration, topological relationship of serum level seemed to be fairly stable (arterial> or =venous blood in most cases), indicating no evident influence of postmortem diffusion. Significant elevation of serum SP-A (76.7-250 ng/ml in left heart blood) was observed in hyaline membrane diseases from various causes independent of the postmortem intervals (<30 h). However, mean SP-A levels in postmortem heart blood were usually low in asphyxia including hanging, strangulation and choking (left, 25.5 ng/ml; right, 22.3 ng/ml), polytrauma (left, 13.1 ng/ml; right, 9.0 ng/ml) and stab wound to the neck (left, 34.1 ng/ml; right, 29.4 ng/ml). Prominent elevation was noted in a case of fatal strangulation with complication of idiopathic interstitial pneumonia, and also in some deaths due to drowning, burns in fires, blunt and gunshot chest injuries. These findings indicated that postmortem elevation of serum SP-A levels was associated with alveolar septal damage due to inflammation, mechanical and physical stresses, which caused leakage of SP-A into the bloodstream.     

Creating problems as part of the "solution": the JCAHO Sentinel Event Policy, legal issues, and patient safety

The recently reported number of patient deaths attributable to medical errors is staggering. In response to this crisis, the Joint Commission on Accreditation of Healthcare Organizations ("JCAHO") proposed its Sentinel Event Policy. The policy mandates self-reporting by hospitals accredited by the JCAHO. This Article argues that the JCAHO's policy shows an inattention to the legal realities of discovery and absence of immunity. Until the JCAHO addresses these issues, self-reporting will have limited success. This Article suggests that to promote patient safety, self-regulatory reports should go to a neutral, nonsanctioning third party, an approach adopted from aviation's highly successful reporting system.     

Older workers' progression from private disability benefits to Social Security disability benefits

People with medical conditions that limit their ability to work tend to receive short-term disability benefits initially and may then move to long-term and eventually to permanent disability benefits. The progression of older workers (those aged 55 to 64) along that continuum of benefits is documented here with data from a large disability insurance company. The data show that older workers who receive short-term medical disability benefits are three times as likely as younger workers to progress to receipt of Social Security Disability Insurance (SSDI) benefits, although a slight reversal of that trend occurs as workers pass age 62. Musculoskeletal conditions are the most frequent basis of short-term disability claims among older workers, with circulatory conditions running a close second. Furthermore, although all medical conditions are more likely to lead to SSDI benefits among older workers, circulatory conditions do so most frequently. This article discusses industry standards for the management of disability claims at each level of severity. It also addresses common and emerging disability management practices that may reduce the likelihood of impaired workers developing long-term or permanent financial dependence on disability benefits programs.     

Delayed pericardial tamponade following a stab wound to a branch of the right coronary artery

A 45-year-old man was attacked with a knife and suffered multiple stab wounds to the chest and abdomen. After surgical treatment and hospitalization for 9 days he was discharged in a stable condition. The following day he was found dead in his apartment. The autopsy revealed a pericardial tamponade caused by acute bleeding from an injured branch of the right coronary artery. This case shows that life-threatening late complications in patients with penetrating cardiac wounds may occur despite an initially uneventful course.     

The significance of the legal term "corpse" in forensic medicine

The definition of the term "corpse" is relevant for medicine in general and most particularly so for forensic medicine, as it has direct consequences on practical work: legally, postmortems and autopsies may only be performed on corpses. With this in mind, the legal term "corpse" was examined on the basis of German State Law regulations and provisions. Approximately half the burial acts include a definition of "corpse", but even here there are certain variations. The definitions for "corpse" can be divided into four categories: 1) according to the lack of vital signs or sure signs of death 2) according to the degree of decomposition and/or cohesion of body parts 3) on the basis of severed body parts, and 4) terminological differentiation of stillbirths and neonatal fatalities from miscarriages. Laws vary greatly in their definition of the term "corpse". Therefore, the decision whether or not human remains or parts thereof qualify as a "corpse" should be left to medical discretion.     

Not enough help for themselves--the risk of physicians to commit suicide

Physicians seem unwilling to deal with their own suicidal problems professionally. Suicide is a repressed topic. According to international studies, medical students and physicians are clearly over-represented among suicide victims. Committing suicide stands in sharp contrast to the positive image physicians enjoy as competent, strong helpers transmitting positive energy. Various studies and meta-analyses show that physicians use knowledge specific to their profession and are therefore "more successful" than the general population in committing suicide. Moreover, the data reveal a number of risk factors specifically correlating with medical practice. This is confirmed by an increased number of suicides during medical training and professional life in comparison with the general population. Gender-specific analyses show an even higher suicide risk for female physicians. In this context it cannot be excluded that out of "professional respect" cardiovascular causes of death are sometimes falsely documented in death certificates instead of suicide. Despite their special education, physicians are not very good at diagnosing their own emotional disorders and asking colleagues for adequate professional help. They rather tend to camouflage their own psychological problems also because they are afraid of occupational and personal discrimination.     

Survived crossbow injuries

The Hamburg University Institute of Legal Medicine presents 2 cases of injuries of crossbow arrows where the patients survived. Crossbows are used nowadays as sports and hunting weapons. They are freely obtainable, and since people without practice can shoot them, there are constant injuries and fatal cases. Crossbow arrows have a high penetration force and can even pierce bone. Depending on the tip of the arrow used, they bore or cut through tissue, here damage to the tissue being restricted to the direct surroundings. Due to the elasticity of the tissue, the arrow shaft in the wound track may have the effect of an incomplete tamponade so that major hemorrhaging is prevented. In this condition, the injured person may be conscious and capacitated. From the medical viewpoint, crossbow arrows should therefore be invariably left in the wound, secured against displacement during transport, and only removed in the hospital.
