The co-ordination of the interdisciplinary care of the multi traumapatient by the Trauma Service staff has promoted a collaborativeapproach to the management of the multiply injured patient.

Prevalence of Patient Controlled Analgesia (PCA) in multipletrauma: A seven-year restrospective analysis of prospectivedata at a level 1 metropolitan trauma centre

Background: Acute pain control formulates a key component inpolytrauma management. Patient Controlled Analgesia (PCA) hasbeen utilised in the last decade. Very little literature is available todate on the prevalence, usage and role of PCA in multiple trauma.Aim: To study the prevalence and pattern of usage of PCA inpolytrauma patientsMethod: A retrospective analysis of prospectively collected data onpolytrauma patients admitted to a Level 1 Trauma Centre over aperiod of seven years was undertaken. Detailed analysis ofdemographic data, injury severity, injury pattern and types ofanalgesia were performed in a cohort of patients on PCA.Results: A total of 8599 patients were admitted to a Level 1 TraumaCentre over a period of seven years. Oral analgesics remain by farthe most prevalent (n = 3195) type of analgesia used in our traumainpatient population, followed by parenteral opiates (n = 987), PCA(n = 822) and opiate infusion (n = 573). Epidural analgesia wasused in a very small number of patients (n = 4). Out of the total8,599 patients, 822 patients received PCA during their hospitalisa-tion. 75.3% of PCA patients were males. The mean age of the PCAinpatients was 41.9 years. 35.6% of PCA patients have severepolytrauma with an Injury Severity Score(ISS) greater than 15.Extremities injuries (n = 633), soft tissues injuries (n = 508) andchest injuries (n = 429) were the most prevalent injuries inpolytrauma receiving PCA. PCA alone was used in more than half(n = 446) of trauma patients.Conclusion: Pattern of PCA use is around 10% in polytraumapatients. Injury Severity Scores is not a good indicator of PCA usage.PCA alone was an adequate mode of analgesia in more than half oftrauma patients. PCA is commonly used in injuries involvingextremities, soft tissues and chest. The prevalence of epiduralanalgesia is extremely low. There is a scope for further increaseduse of PCA in acute pain management in trauma patients. Furtherresearch is required to evaluate the role of PCA in polytrauma withmild head injury.

Background: Delayed union and nonunion are complications offracture healing that remain problematic to treat. They arepotentially chronic conditions associated with pain and withfunctional and psychosocial disability. Although studies haveinvestigated the patient-reported outcomes of different treat-ments of delayed fracture healing, the overall health outcomes ofdelayed union and nonunion have yet to be documented. Thisstudy aims to compare the differences in health outcomes ofpatients with delayed fracture healing (delayed union and
nonunion) and those with union of diaphyseal fractures treatedat two major metropolitan trauma centres in Victoria.Methods: 872 fractures of the clavicle, humerus, radius, ulna,femur, tibia and fibula in 695 adult patients followed up by theVictorian Orthopaedic Trauma Outcomes Registry (VOTOR) wereincluded in the study; 95 fractures in 66 patients were excluded.Hospital medical records were reviewed to identify the healingoutcome of each fracture. Prospectively gathered VOTOR healthoutcome measurements, including the Short Form 12-Item HealthSurvey (SF-12), at 6 and 12 months post injury were thencompared to each fracture outcome.Results: Response rate for the SF-12 was 65.5% at 12 months postinjury. 16.7% of fractures demonstrated evidence of delayedhealing. The most frequently affected bones in this group werethe tibia (41.1%), femur (28.1%) and clavicle (17.8%), while the mostcommon mechanisms of injury were motorcycle (34.9%) andmotor vehicle (27.4%) accident. The median SF-12 Physical andMental Component Summary scores at 12 months post injury forthe tibia, femur and clavicle were lower in the delayed fracturehealing group compared to the fracture union group.Conclusion: Delayed union and nonunion are common complica-tions of fracture healing post trauma, often requiring furthersurgical intervention. Patients with delayed healing of diaphysealfractures generally have reduced physical and mental health at 12months post injury compared to patients with successful primaryfracture union. However, these preliminary results need to bevalidated with further analyses, including accounting for con-founding variables and testing for statistical significance.

AIS 2005 vs. AIS 1998—A double-coding exercise to identifyissues for trauma data
Cameron PalmerRoyal Children’s Hospital, Melbourne, Australia
Background: The 2005 version of the Abbreviated Injury Scale(AIS05) potentially represents a significant change in injuryspectrum classification, due to a substantial increase in the numberof codes used, and alterations to the agreed severity of a number ofinjury types when compared to the previous version (AIS98). While asignificant proportion of trauma registries around the world aremoving to adopt AIS05, its effect on patient classification in existingregistries, and the optimum method of comparing existing datacollections with new AIS05 collections are largely unknown.Objectives: To assess the potential impact of adopting the AIS05codeset in an established trauma system, and to identify issuesassociated with this change.Methods: A current subset of consecutive major trauma patientsadmitted to the Royal Children’s Hospital Melbourne and TheAlfred Hospital were double-coded using both AIS98 and AIS05.Resulting codesets were assessed for concordance in codes used,injury severity and calculated injury severity scores.Results: 602 injuries sustained by 109 patients were compared.Individual injury severities, and patient injury severity scoresdiffered markedly between codesets. Discrepancies in dataconsistency were more common in head and chest injuries. Datamapped to a different codeset performed better in comparisonsthan raw AIS98 and AIS05 codesets.Conclusions: It is felt that this review contributes significantly toour knowledge of AIS codeset change impact on establishedtrauma registries, and validates the concept of code mappingbetween AIS versions. The effect of AIS05 on major traumadefinition and patient numbers will be discussed.
