ChIP: An early activation protocol for isolated blunt chest injury improves outcomes, a retrospective cohort study.

BACKGROUND: Blunt chest injuries not treated in a timely manner with sufficient analgesia, physiotherapy and respiratory support are associated with increased morbidity and mortality. The aim of the study was to determine the impact of a blunt chest injury early activation protocol (ChIP) on patient and hospital outcomes. METHODS: In this pre-post cohort study, the outcomes of patients with blunt chest injury who received ChIP were compared against those who did not. Data including injury severity, patient outcomes, hospital treatments and comorbidites were extracted from medical records. The primary outcome was pneumonia. Secondary outcomes evaluated health service delivery. Logistic and multiple regressions were used to adjust for potential confounding variables. RESULTS: 546 patients were included, 273 in the before-ChIP cohort and 273 in the after-ChIP cohort. The incidence of pneumonia following the introduction of ChIP was reduced by 4.8% (95% CI 0.5-9.2, p=0.03). In the after-ChIP cohort, more patients received a pain team review (32% vs. 13%, p<0.001), physiotherapy (93% vs. 86%, p=0.005) and trauma team review (95% vs. 39%, p<0.001). There was no difference in length of stay (p=0.50). CONCLUSIONS: ChIP improved the delivery of healthcare services and reduced the rate of pneumonia among patients with isolated chest trauma.

Physician staffed helicopter emergency medical service case identification - a before and after study in children.

BACKGROUND: Severely injured children may have better outcomes when transported directly to a Paediatric Trauma Centre (PTC). A case identification system using the crew of a physician staffed helicopter emergency medical service (P-HEMS) that identified severely injured children for P-HEMS dispatch was previously associated with high rates of direct transfer. It was theorised that discontinuation of this system may have resulted in deterioration of system performance. METHODS: Severe paediatric trauma cases were identified from a state based trauma registry over two time periods. In Period A the P-HEMS case identification system operated in parallel with a paramedic dispatcher (Rapid Launch Trauma Co-ordinator-RLTC) operating from a central control room (n = 71). In Period B the paramedic dispatcher operated in isolation (n = 126). Case identification and direct transfer rates were compared as was time to arrival at the PTC. RESULTS: After cessation of the P-HEMS system the rate of case identification fell from 62 to 31 % (P < 0.001), identification of fatal cases fell from 100 to 47 % (P < 0.001), the rate of direct transfer to a PTC fell from 66 to 53 % (P = 0.076) and the time to arrival in a PTC increased from a median 69 (interquartile range 52 - 104) mins to 97 (interquartile range 56 - 305) mins (P = 0.003). When analysing the rate of direct transfer to a PTC as a function of team composition, after adjusting for age and injury severity scores, there was no change in the rate between the physician and paramedic groups across the two time periods (relative risk 0.92, 95 % CI: 0.44 to 1.41). DISCUSSION: The parallel identification system improves case identification rates and decreases time to arrival at the PTC, whilst requiring RLTC authorisation preserves the safety and efficiency benefits of centralised dispatch. The model could be extended to adult patients with similar benefits. CONCLUSIONS: A case identification system relying solely on RLTC paramedics resulted in a significantly lower case identification rate and increased prehospital time with a non-significant fall in direct transfer rate to the PTC. The elimination of the P-HEMS input from the tasking system resulted in worse performance indicators and has the potential for poorer outcomes.

Acute costs and predictors of higher treatment costs of trauma in New South Wales, Australia.

BACKGROUND: Accurate economic data are fundamental for improving current funding models and ultimately in promoting the efficient delivery of services. The financial burden of a high trauma casemix to designated trauma centres in Australia has not been previously determined, and there is some evidence that the episode funding model used in Australia results in the underfunding of trauma. AIM: To describe the costs of acute trauma admissions in trauma centres, identify predictors of higher treatment costs and cost variance in New South Wales (NSW), Australia. MATERIALS AND METHODS: Data linkage of admitted trauma patient and financial data provided by 12 Level 1 NSW trauma centres for the 08/09 financial year was performed. Demographic, injury details and injury scores were obtained from trauma registries. Individual patient general ledger costs (actual trauma patient costs), Australian Refined Diagnostic Related Groups (AR-DRG) and state-wide average costs (which form the basis of funding) were obtained. The actual costs incurred by the hospital were then compared with the state-wide AR-DRG average costs. Multivariable multiple linear regression was used for identifying predictors of costs. RESULTS: There were 17,522 patients, the average per patient cost was $10,603 and the median was $4628 (interquartile range: $2179-10,148). The actual costs incurred by trauma centres were on average $134 per bed day above AR-DRG costs-determined costs. Falls, road trauma and violence were the highest causes of total cost. Motor cyclists and pedestrians had higher median costs than motor vehicle occupants. As a result of greater numbers, patients with minor injury had comparable total costs with those generated by patients with severe injury. However the median cost of severely injured patients was nearly four times greater. The count of body regions injured, sex, length of stay, serious traumatic brain injury and admission to the Intensive Care Unit were significantly associated with increased costs (p<0.001). CONCLUSION: This multicentre trauma costing study demonstrated the feasibility of trauma registry and financial data linkage. Discrepancies between the observed costs of care in these 12 trauma centres and the NSW average AR-DRG costs suggest that trauma care is currently underfunded in NSW.

Injury trends and mortality in adult patients with major trauma in New South Wales.

OBJECTIVE: To examine trends in mechanism and outcome of major traumatic injury in adults since the implementation of the New South Wales trauma monitoring program, and to identify factors associated with mortality. DESIGN AND SETTING: Retrospective review of NSW Trauma Registry data from 1 January 2003 to 31 December 2007, including patient demographics, year of injury, and level of trauma centre where definitive treatment was provided. PARTICIPANTS: 9769 people aged ≥ 15 years hospitalised for trauma, with an injury severity score (ISS) > 15. MAIN OUTCOME MEASURES: The NSW Trauma Registry outcome measures included were overall hospital length of stay, length of stay in an intensive care unit and in ospital mortality. RESULTS: There was a decreasing trend in severe trauma presentations in the age group 16-34 years, and an increasing trend in presentations of older people, particularly those aged ≥ 75 years. Road trauma and falls were consistently the commonest injury mechanisms. There were 1328 inhospital deaths (13.6%). Year of injury, level of trauma centre, ISS, head/neck injury and age were all independent predictors of mortality. The odds of mortality was significantly higher among patients receiving definitive care at regional trauma centres compared with Level I centres (odds ratio, 1.34; 95% CI, 1.10-1.63). CONCLUSIONS: Deaths from major trauma in NSW trauma centres have declined since 2003, and definitive care at a Level 1 trauma centre was associated with a survival benefit. More comprehensive trauma data collection with timely analysis will improve injury surveillance and better inform health policy in NSW.

Learning surgical communication, leadership and teamwork through simulation.

BACKGROUND: In Australia and New Zealand, surgical trainees are expected to develop competencies across 9 domains. Although structured training is provided in several domains, there is little or no formal program for professionalism, communication, collaboration, and management and leadership. The Australian federal Department of Health and Aging funded a pilot course in simulation-based education to address these competencies for surgical trainees. This article describes the course and evaluation. METHODS: Course development: Content and methods drew on best-evidence for teaching and learning these competencies from other disciplines. Course evaluation: Participants completed surveys using rating scales and free text comments to identify aspects of the course that worked well and those that needed improvement. RESULTS: Eleven of 12 participants completed evaluation forms immediately after the course. Participants reported largely meeting learning objectives and valuing the educational methods. High levels of realism in simulations contributed to the ease with which participants immersed themselves in scenarios. CONCLUSIONS: This study demonstrates that a course designed to teach competencies in communication, teamwork, leadership, and the encompassing professionalism to surgical trainees is feasible. Although participants valued the content and methods, they identified areas for development. Limitations of the evaluation are highlighted, and further areas for research are identified.

Outcomes of severely injured adult trauma patients in an Australian health service: does trauma center level make a difference?

BACKGROUND: Trauma centers are designated to provide systematized multidisciplinary care to injured patients. Effective trauma systems reduce patient mortality by facilitating the treatment of injured patients at appropriately resourced hospitals. Several U.S. studies report reduced mortality among patients admitted directly to a level I trauma center compared with those admitted to hospitals with less resources. It has yet to be shown whether there is an outcome benefit associated with the "level of hospital" initially treating severely injured trauma patients in Australia. This study was designed to determine whether the level of trauma center providing treatment impacts mortality and/or hospital length of stay. METHODS: Outcomes were evaluated for severely injured trauma patients with an Injury Severity Score (ISS) > 15 using NSW Institute of Trauma and Injury Management data from 2002-2007 for our regional health service. To assess the association between trauma centers and binary outcomes, a logistic regression model was used. To assess the association between trauma centers and continuous outcomes, a multivariable linear regression model was used. Sex, age, and ISS were included as covariates in all models. RESULTS: There were 1,986 trauma presentations during the 6-year period. Patients presenting to a level III trauma center had a significantly higher risk of death than those presenting to the level I center, regardless of age, sex, ISS, or prehospital time. Peer review of deaths at the level III center identified problems in care delivery in 15 cases associated with technical errors, delay in decision making, or errors of judgement. CONCLUSION: Severely injured patients treated at a level III center had a higher mortality rate than those treated at a level I center. Most problems identified occurred in the emergency department and were related to delays in care provision. This research highlights the importance of efficient prehospital, in-hospital, and regional trauma systems, performance monitoring, peer review, and adherence to protocols and guidelines.

Laparoscopic hepatectomy, a systematic review.

This systematic review was undertaken to assess the published evidence for the safety, feasibility and reproducibility of laparoscopic liver resection. A computerized search of the Medline and Embase databases identified 28 non-duplicated studies including 703 patients in whom laparoscopic hepatectomy was attempted. Pooled data were examined for information on the patients, lesions, complications and outcome. The most common procedures were wedge resection (35.1%), segmentectomy (21.7%) and left lateral segmentectomy (20.9%). Formal right hepatectomy constituted less than 4% of the reported resections. The conversion and complication rates were 8.1% and 17.6%, respectively. The mortality rate over all these studies was 0.8% and the median (range) hospital stay 7.8 days (2-15.3 days). Eight case-control studies were analysed and although some identified significant reductions in-hospital stay, time to first ambulation after surgery and blood loss, none showed a reduction in complication or mortality rate for laparoscopically carried out resections. It is clear that certain types of laparoscopic resection are feasible and safe when carried out by appropriately skilled surgeons. Further work is needed to determine whether these conclusions can be generalized to include formal right hepatectomy.
