Interpretation of emergency CT scans in polytrauma: trauma surgeon vs radiologist

Introduction: Time is critical in the trauma setting. Emergency computed tomography (CT) scans are usually interpreted by the attending doctor and plans to manage the patient are implemented before the formal radiological report is available. This study aims to investigate the discrepancy in interpretation of emergency whole body CT scans in trauma patients by the trauma surgeon and radiologist and to determine if the difference in trauma surgeon and radiologist interpretation of emergency trauma CT scans has an impact on patient management. Method: This prospective observational comparative study was conducted over a 6 month period (01 April­30 September 2016) at the Inkosi Albert Luthuli Central Hospital which has a level 1 trauma department. The study population comprised 62 polytrauma patients who underwent a multiphase whole body CT scans as per the trauma imaging protocol. The trauma surgeons' initial interpretation of the CT scan and radiological report were compared. All CT scans reported by the radiology registrar were reviewed by a consultant radiologist. The time from completion of the CT scan and completion of the radiological report was analysed. Results: Since the trauma surgeon accompanied the patient to radiology and reviewed the images as soon as the scan was complete, the initial interpretation of the CT was performed within 15­30 min. The median time between the CT scan completion and reporting turnaround time was 75 (16­218) min. Critical findings were missed by the trauma surgeon in 4.8% of patients (bronchial transection, abdominal aortic intimal tear and cervical spine fracture) and non-critical/incidental findings in 41.94%. The trauma surgeon correctly detected and graded visceral injury in all cases. Conclusion: There was no significant discrepancy in the critical findings on interpretation of whole body CT scans in polytrauma patients by the trauma surgeon and radiologist and therefore no negative impact on patient management from missed injury or misdiagnosis. The turnaround time for the radiology report does not allow for timeous management of the trauma patient

Trauma burden, patient demographics and care-process in major hospitals in Tanzania: a needs assessment for improving healthcare resource management

Background:Appropriate referrals of injured patients could improve clinical outcomes and management ofhealthcare resources. To gain insights for system development, we interrogated the current situation by assessingburden, patient demography, causes of injury, trauma mortality and the care-process.Methods:We used an observational, cross-sectional study design and convenience sampling to review patientcharts from 3 major hospitals and the death registry in Tanzania.Results:Injury constitutes 9­13% of the Emergency Centre census. Inpatient trauma-deaths were 8%; however,the trauma death registryfigures exceeded the'inpatient deaths'and recorded up to 16%. Most patients arrivethrough a hospital referral system (82%) and use a hospital transport network (76%). Only 8% of the traumaadmissions possessed National Health Insurance. Road traffic collision (RTC) (69%), assault (20%) and falls (9%)were the leading causes of injury. The care process revealed a normal primary-survey rate of 73­90%.Deficiencies in recording were in the assessment of: Airway and breathing (67%), circulation (40%) and dis-ability (80%). Most patients had non-operative management (42­57%) or surgery for wound care or skeletalinjuries (43%). Laparotomies were performed in 26%, while craniotomy and chest drain-insertion were eachperformed in 10%.Conclusion:The burden of trauma is high, and the leading causes are: RTC, assault, and falls. Deaths recorded inthe death registries outweigh in-hospital deaths for up to twofold. There are challenges in the care process,funding and recording. We found a functional hospital referral-network, transport system, and death registry

Preventative measures taken against hypothermia in selected Durban hospitals' emergency centres and operating theatres

Introduction:Hypothermia is common in emergency general surgical patients. It is known to be associated with major complications in multiple organ systems. It is also easily preventable with the use of safe and cost-effective equipment. However, by observation, it appears that this equipment is used too infrequently thus resulting in unnecessary harm to patients.Methods:This descriptive, observational, cross-sectional study was conducted in two arms to evaluate both emergency centres and operating theatres in the major state hospitals in Durban. It was conducted as an audit as well as a questionnaire-based study, to ascertain the availability of equipment used to prevent hypothermia and also how appropriately the equipment was being used.Results:There was good availability of equipment in both the operating theatres and the emergency centres. However it was being used very poorly, particularly in emergency centres (41% of responses deemed not beneficial to patients versus 29% from operating theatres; 39% of answers beneficial versus 54% from operating theatres.Institutions with hypothermia-prevention protocols scored significantly better than those without a protocol (59% versus 25% beneficial; p = 0.01.Conclusion: In the field of hypothermia prevention, there was sufficient equipment to result in optimal patient care. However there appears to be a lack of knowledge amongst health care providers, resulting in suboptimal use of this equipment.Protocolised management may provide a solution to this problem and improve patient outcomes

Lactate clearance predicts outcome after major trauma

Introduction:To determine a correlation between lactate clearance within 48h and survival in trauma patients at a Level I trauma centre in a developing country and compare to previous international lactate clearance studies.Methods:We conducted a retrospective study of a prospectively collected database at a Level I trauma centre from March 2007 to November 2010. Patients of all ages were included. Metabolic parameters from initial arterial blood gas were measured in all patients; an abnormal lactate beindefined as 2.5mmol/L. A subgroup analysis of blunt versus penetrating injury was performed. Results:Of the 657 patients in the database; 493 had complete lactate data. The survival rate of patients with lactate values 2.5mmol/L was 88. Of the patients with high lactate levels that cleared within 24 and 48h the survival rates were 81 and 71; respectively. The survival rate amongst patients not achieving a normal lactate within 48h was 46 but was higher in those with penetrating as opposed to blunt injury (67 versus 38). The overall survival was 81.Conclusion:The present results confirm previous studies showing that prolonged lactate clearance predicts increased mortality in severely injured trauma patients. Thus; the measurements of arterial serum lactate trends are simple and effective predictors of outcome
