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.

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.

Management of severe trauma in intensive care units and surgical wards.

OBJECTIVE: To evaluate the management of severe trauma in intensive care, high dependency and general surgical wards of Victorian hospitals. DESIGN: Retrospective case review by multidisciplinary committees. SUBJECTS: The first 256 people who died from road traffic accidents who were alive on the arrival of emergency services between 1 July 1992 and 30 June 1994. MAIN OUTCOME MEASURES: (1) Severity of injury according to clinical diagnosis, autopsy findings and recognised trauma-scoring methods; (2) errors in management, identified as contributing or not contributing to the cause of death, and categorised as "management", "system", "diagnostic" or "technique" errors. RESULTS: Most patients (61%) were admitted to an intensive care unit (ICU), and 19.5% were admitted to high dependency or general surgical wards. Of 2187 errors of care identified, 11.8% occurred in ICU and 6.7% in wards, with the remainder occurring during the earlier phases of care. Most errors were classified as management errors (82% of ICU errors and 88% of ward errors). Fifty-two per cent of ICU errors and 71% of ward errors were judged to contribute to the patient's death. CONCLUSIONS: A significant number of errors of trauma management occur in the intensive care and general surgical ward. Improvement in late trauma care may reduce the number of preventable trauma deaths.

Quality assessment of the management of road traffic fatalities at a level I trauma center compared with other hospitals in Victoria, Australia. Consultative Committee on Road Traffic Fatalities in Victoria.

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.

Reproducibility of preventable death judgments and problem identification in 60 consecutive road trauma fatalities in Victoria, Australia. Consultative Committee on Road Traffic Fatalities in Victoria.

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.

Management deficiencies and death preventability in 120 Victorian road fatalities (1993-1994). The Consultative Committee on Road Traffic Fatalities in Victoria.

BACKGROUND: 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: survival probability between 25 and 75%). METHODS: For 1993-94, 120 consecutive fatality cases surviving until arrival of ambulance services were evaluated by analysis and discussion of their complete pre-hospital, hospital and autopsy records. RESULTS: A total of 1175 problems were identified in 455 admission to the various areas of care. A total of 949 problems (81%) were found to be management errors and 123 (11%) were found to be system inadequacies. Technique errors (35 (3%)), diagnosis delays (27 (2%)) and diagnosis errors (41 (4%)) were less frequent. The emergency department (ED) accounted for 662 (56%) problems, followed by 191 (16%) pre-hospital problems and 140 (12%) intensive care unit (ICU) problems. There were 598 (51%) problems that were assessed as contributing to death. A total of 308 (52%) problems occurred in the ED, 106 (18%) were pre-hospital problems and 71 (12%) occurred in ICU. Management errors comprised 465 (78%) problems contributing to death, and system inadequacies comprised 76 (13%) problems. Resuscitation problems accounted for 101 (40%) of the 254 ED management errors contributing to death. A total of 79 (66%) deaths were assessed as non-preventable, five (4%) were assessed as preventable and 36 (30%) were assessed as potentially preventable. CONCLUSIONS: Organization and educational countermeasures are required to reduce the high frequency of problems in emergency services and clinical management.

Evaluation of the medical management and preventability of death in 137 road traffic fatalities in Victoria, Australia: an overview. Consultative Committee on Road Traffic Fatalities in Victoria.

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.

Bicyclist head injury prevention by helmets and mandatory wearing legislation in Victoria, Australia.

After a decade of promotion and education, legislation for mandatory helmet wearing by bicyclists in Victoria was introduced on 1 July 1990. The legislation was a world first. Comparison of 1710 bicyclist casualties wearing and not wearing helmets has demonstrated that wearing helmets certified to the Australian Standard reduces the head injury risk by at least 39% and lessens head injury severity. Simulated impact testing of helmets has shown that they provide protection in most impacts including collisions involving a motor vehicle. Legislation for mandatory helmet wearing in Victoria has led to increased wearing rates and marked reductions in bicyclist fatalities and head injuries. The Victorian experience gives substantial support to the introduction of legislation for mandatory helmet wearing by bicyclists.

Trauma audit and quality improvement.

Audit is the evaluation of patient care. The care of the injured patient commences at the accident scene and involves prehospital triage and management, emergency hospital assessment and resuscitation, diagnostic and therapeutic interventions, operative surgery, intensive care unit management, acute hospital care and rehabilitation. Audit assesses the delivery of trauma care and clinical management and through identification of inadequacies facilitates the introduction of appropriate improvements. Both the American National Academy of Sciences--National Research Council and the Australian National Health & Medical Research Council have recommended the establishment of an audit process to evaluate the quality of trauma management and to obtain quality assurance. They have advised that this process would be assisted by the development of regional trauma registries and a uniform approach to the grading of injuries. Reduction in the preventable death rate, frequency of complications and duration of hospitalization has followed audits as a result of changes in the organization and quality of trauma care. In the United States, for example, the preventable death rate after injury was reduced from 35 to 15% in Orange County, California and from 14 to 3% in San Diego County, California. Studies from Great Britain. The Netherlands, Canada, Australia and elsewhere have further supported the view that trauma audit modifies practice leading to reductions in mortality and morbidity.

The effectiveness of bicyclist helmets: a study of 1710 casualties.

During the 1980s, a sustained campaign increased the rates of helmet use of Victorian bicyclists. The efficacy of helmet use was evaluated by comparison of crashes and injuries (AIS-1985) in 366 helmeted (261 Australian Standard approved and 105 non-approved) and 1344 unhelmeted casualties treated from 1987 through 1989 at Melbourne and Geelong hospitals or dying before hospitalization. Head injury (HI) occurred in 21.1% of wearers of approved helmets and in 34.8% of non-wearers (p < 0.001). The AIS scores were decreased for wearers of approved helmets (p < 0.001), face injuries were reduced (p < 0.01), and extremity/pelvic girdle injuries increased (p < 0.001) and the overall risk of HI was reduced by at least 39% and face injury by 28%. When casualties with dislodged helmets were excluded, HI was reduced 45% by approved helmets. Head injury reduction by helmets, although substantial, was less than that found in a similar study in Seattle, Washington.

Cancer risk in relatives of patients with common colorectal cancer.

OBJECTIVE: To quantify any risk for colorectal cancer in first-degree relatives of patients with common colorectal cancer and to define possible markers for increased risk. DESIGN: Case-control family study. PATIENTS: Relatives of colorectal cancer patients and of matched control patients from a one-surgeon practice. METHODS: Family medical histories were obtained for 7493 first-degree relatives and 1015 spouses of 523 case-control pairs. Reported diagnoses of colorectal cancer in relatives were verified in 79% of instances. RESULTS: By case-control analysis, the odds ratio was 1.8 (95% CI, 1.2 to 2.7) for one and 5.7 (CI, 1.7 to 19.3) for two affected relatives. By matched analysis of risk in relatives, the increased risk to parents and siblings was 2.1 times greater for case patients than for control patients (CI, 1.4 to 3.1); 3.7 times greater (CI, 1.5 to 9.1) with case patients diagnosed before 45; and 1.8 times greater (CI, 1.2 to 2.9) with case patients diagnosed at 45 years or older; and was independent of gender, type of relative, site of cancer, and type of cancer (single or multiple). The cumulative incidence among first-degree relatives was greater for case patients than for control patients (P < 0.001), and in case patients, greater for those diagnosed before 55 years of age (P < 0.001). The cumulative incidence (+/- S.E.) to age 80 was 11.1% +/- 1.3%, 7.3% +/- 0.8%, and 4.4% +/- 1.0% among relatives of case patients diagnosed before age 45 years, between 45 and 54 years, and at 55 years or older, respectively, and was 2.4% +/- 0.6% in relatives of control patients. CONCLUSIONS: First-degree relatives of patients with common colorectal cancer have an increased risk for colorectal cancer. This risk is greater if diagnosis was at an early and is greater when other first-degree relatives are affected. This increased risk should be considered when formulating screening strategies.

Helmet efficacy in the prevention of bicyclist head injuries: Royal Australasian College of Surgeons initiatives in the introduction of compulsory safety helmet wearing in Victoria, Australia.

The results of a comparative study of the injury profiles of Victorian motorcyclist and bicyclist casualties were used by the Royal Australasian College of Surgeons in initiating a state-wide campaign to promote the wearing of approved safety helmets by Victorian bicyclists and to obtain the necessary legislation whereby such wearing would become compulsory. Bicyclist casualties had sustained more frequent and severe head injuries than motorcyclist casualties although the latter had sustained overall more severe body injuries. Increases in voluntary helmet wearing rates and reductions in costs preceded the introduction in July, 1990 in Victoria of compulsory safety helmet wearing by bicyclists. Sixty-four helmets obtained during a study of more than 1,700 Victorian bicyclists wearing and not wearing helmets were evaluated for performance by impact severity testing and findings related to head injury occurrence. Sixteen helmets sustained more than one impact during the accident. All casualties who sustained a severe head injury (Abbreviated Injury Scale greater than or equal to 4) were involved in a collision with a motor vehicle and subjected to more than one impact to the head/helmet and/or the helmet had come off during the accident. Most impacts occurred below the current test lines of Australian and United States standards. Ten percent of impacts were more severe than required in performance standards. Recommendations are made for improvements in the current standard.
