Evaluation of the medical management and preventability of death in 137 road traffic fatalities in Victoria, Australia: An overview

OBJECTIVES In 1992 a multidisciplinary committee was established to identify problems in the management of road fatalities in Victoria, Australia, to assess their contribution to death, and to identify preventable deaths (preventable: survival probability more than 75%; potentially preventable: 25 to 75%). METHODS For 1992 and 1993 all 137 fatality cases surviving until arrival of ambulance services were evaluated by analysis and discussion of their complete prehospital, hospital, and autopsy records. RESULTS 1,012 problems were identified in 509 admissions to the various areas of care. Six hundred eighty-five (68%) were management errors and 217 (21%) were system inadequacies. Technique errors (45 (4%)), diagnosis delays (25 (2%)), and diagnosis errors (40 (4%)) were less frequent. The emergency department (ED) accounted for 537 (53%) problems, followed by prehospital (200 (20%)) and intensive care unit (118 (12%)). Four hundred seventy (46%) problems were assessed as contributing to death. Two hundred twenty-eight (49%) occurred in the ED, 90 (19%) were prehospital problems, and 63 (13%) occurred in the intensive care unit. Management errors comprised 326 (69%) problems contributing to death, and system inadequacies 88 (19%). Resuscitation problems accounted for 82 (49%) of the 167 ED management errors contributing to death. Eighty-five (62%) deaths were assessed as nonpreventable, 7 (5%) as preventable, and 45 (33%) as potentially preventable. CONCLUSION Organizational and educational counter measures are required to reduce the high frequency of problems in emergency services and clinical management.

Quality assessment of the management of road traffic fatalities at a level I trauma center compared with other hospitals in Victoria, Australia

OBJECTIVES Since 1992, the Consultative Committee on Road Traffic Fatalities in Victoria, Australia, has identified problems including those contributing to death and the potential preventability of deaths in road fatalities who survived until at least the arrival of ambulance services. The present analysis examines the outcomes at a Level I trauma center compared with other hospital groups in Victoria. METHODS Between 1992 and 1994, 257 consecutive eligible fatalities were evaluated. Problems in management and preventable deaths were identified at the trauma center (TC) and in pooled data from other hospital groups, i.e., specialist teaching (Level II), other metropolitan (Level III), large regional (Level III), and small regional hospitals. RESULTS Mean problems identified and those contributing to death (controlled for the number of areas of care), were less frequent at TC (1.7 and 0.6) than at other hospital groups (specialist teaching, 1.9 and 1.1*; metropolitan, 3.1* and 1.6*; large regional, 3.8* and 1.8*; small regional, 5.1* and 2.6*) (*p < 0.05 compared with TC). Preventable and potentially preventable deaths were also less common at TC (20%) than at the other hospital groups (specialist teaching, 40%*; metropolitan, 41%*; large regional, 53%*; small regional, 62%*) (*p < 0.05 compared with TC). When a Trauma and Injury Severity Score of 75% or more was used to define preventable death, a similar trend was identified. CONCLUSION Management of patients with major trauma at a Level I trauma center was associated with fewer problems contributing to death and fewer preventable and potentially preventable deaths than at the different hospital groups. A trauma system in Victoria, including bypass of major trauma patients to designated hospitals with 24-hour trauma services, is likely to decrease the frequency of problems, including the preventable death rates.

Gender differences in outcome in patients with hypotension and severe traumatic brain injury

BACKGROUND Animal studies have identified hormonal influences on responses to injury and recovery, creating a potential gender effect on outcome. Progesterone and oestrogen are thought to afford protection in the immediate post-injury period, suggesting females have an advantage, although there has been limited evidence of this in human outcome studies. METHODS This study examined the influence of gender on outcome in 229 adults (151 males), aged >17 years, with severe blunt head trauma, initial GCS <9 and hypotension, recruited into a randomised controlled trial of pre-hospital hypertonic saline resuscitation versus conventional fluid management. Outcome was measured by survival and Glasgow Outcome Scale-Extended version (GOS-E) scores at 6 months post-injury. RESULTS Females recruited into the study had a higher mean age. Females were more likely to be injured as passengers and pedestrians and males as drivers or motorcyclists. There were no gender differences in GCS or injury severity scores, ICP, cerebral perfusion pressure, gas exchange (PaO2/FiO2 ratio), or duration of mechanical ventilation. After controlling for GCS, age and cause of injury, females had a lower rate of survival. They also showed a lower rate of good outcome (GOS-E score >4) at 6 months, but this appeared to reflect the lower rate of initial survival. Those females surviving had similar outcomes to males. CONCLUSIONS The study provides no evidence that females fare better than males following severe TBI, suggesting rather that females may fare worse.

Reproducibility of preventable death judgments and problem identification in 60 consecutive road trauma fatalities in Victoria, Australia

BACKGROUND Since 1992, the Consultative Committee on Road Traffic Fatalities in Victoria has identified problems in the management of traffic fatalities. Its two evaluative committees have additionally assessed the potential preventability of death. Previous studies have shown only poor to fair reproducibility of death judgments. METHODS Problems in the management of 60 consecutive road traffic fatalities and the potential preventability of death were independently evaluated by the two committees. Inter-rater and inter-committee concordance were analyzed using the kappa statistic. RESULTS Reproducibility was high. Inter-committee agreement on nonpreventable, potentially preventable, and preventable death judgments was high (kappa = 0.73, 95% confidence interval = 0.57-0.89). Agreement within the two evaluative committees was also high (average weighted kappa = 0.73 and 0.74). There was good agreement between committees on problems identified, including those contributing to death. CONCLUSION The high kappa concordance on preventable death judgments and the agreement on problem identification supports the reproducibility of the methodology used.

Evaluation of the prehospital management of road traffic fatalities in Victoria, Australia.

INTRODUCTION This study was undertaken to identify prehospital system and management deficiencies and preventable deaths between 01 January 1997 and 31 December 1998 in 243 consecutive Victorian road crash victims with fatal outcomes. METHODS The complete prehospital and hospital records, the deposition to the coroner, and autopsy findings were evaluated by computer analysis and peer group review with multidisciplinary discussion. RESULTS One-hundred eighty-seven (77%) patients had prehospital errors or inadequacies, of which 135 (67%) contributed to death. Three-hundred ninety-four (67%) related to management and 130 (22%) to system deficiencies. Technique errors, diagnosis delays, and errors relatively were infrequent. One of 24 deaths at the crash scene or en route to hospital was considered to be preventable and two potentially preventable. CONCLUSION The high prevalence of prehospital deficiencies has been addressed by a Ministerial Task Force on Trauma and Emergency Services and followed by the introduction of a new trauma care system in Victoria.

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 Committees 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.

The preventability of death in road traffic fatalities with head injury in Victoria, Australia

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.
