Abstract	Background: Contamination of the surgeon during gowning is a possible risk factor for prosthetic joint infection in arthroplasty surgery. Surgical helmets are a common form of personal protective equipment used during this type of surgery. Increasingly, there is a focus on the methods of application of the surgical hood and gown while wearing these helmets. Methods: Ultraviolet fluorescent powder was used to represent air-borne contaminant and applied through the airflow inlet of the surgical helmet. Seven methods of helmet and surgical gown application methods were examined. A ultraviolet torch was used to determine the level of contamination across 11 body regions. A single body region with less than 10 particles was classified as minor contamination, and over 10 particles as major contamination. Results: Early activation of the surgical helmet resulted in significant level of contamination across the majority of body regions. Major contamination also affected the scrub nurse when applying the surgical hood to the surgeon's helmet. Late activation of helmet system resulted in only minor level of contamination to the surgeon's shoulders and forearms. Adhesive wrist wraps over the inner gloves did not decrease contamination when added to late activation of the helmet. Conclusion: It is our recommendation that the surgical hood should be applied by an unsterile theater assistant and that the surgical helmet system should be activated after the surgeon has applied inner gloves to minimize the level of contamination to the surgeon's gown.

Abstract	Background: Recently, retrospective registry-based studies have reported the decreasing incidence and increasing mortality of postinjury multiple organ failure (MOF). We aimed to describe the current epidemiology of MOF following the introduction of haemostatic resuscitation. Methods: A 10-year prospective cohort study was undertaken at a Level-1 Trauma Centre-based ending in December 2015. Inclusion criteria age ≥ 16 years, Injury Severity Score (ISS) > 15, Abbreviated Injury Scale (AIS) Head < 3 and survived > 48 h. Demographics, physiological and shock resuscitation parameters were collected. The primary outcome was MOF defined by a Denver Score > 3. Secondary outcomes: intensive care unit length of stay (ICU LOS), ventilation days and mortality. Results: Three hundred and forty-seven patients met inclusion criteria (age 48 ± 20; ISS 30 ± 11, 248 (71%) were males and 23 (6.6%) patients died. The 74 (21%) MOF patients (maximum Denver Score: 5.5 ± 1.8; Duration; 5.6 ± 5.8 days) had higher ISS (32 ± 11 versus 29 ± 11) and were older (54 ± 19 versus 46 ± 20 years) than non-MOF patients. Mean daily Denver scores adjusted for age, sex, MOF and ISS did not change over time. Crystalloid usage decreased over the 10-year period (p value < 0.01) and PRBC increased (p value < 0.01). Baseline cumulative incidence of MOF at 28 days was 9% and competing risk analyses showed that incidence of MOF increased over time (subdistribution hazard ratio 1.14, 95% CI 1.04 to 1.23, p value < 0.01). Mortality risk showed no temporal change. ICU LOS increased over time (subdistribution hazard ratio 0.95, 95% CI 0.92 to 0.98, p value < 0.01). Ventilator days increased over time (subdistribution hazard ratio 0.94, 95% CI 0.9 to 0.97, p value < 0.01). Conclusion: The epidemiology of MOF continues to evolve. Our prospective cohort suggests an ageing population with increasing incidence of MOF, particularly in males, with little changes in injury or shock parameters, who are being resuscitated with less crystalloids, stay longer on ICU without improvement in survival.

Abstract	Objective: To describe the health characteristics, condition-specific measures, chronic disease risk factors, and healthcare and medication use over time of individuals with musculoskeletal conditions awaiting orthopaedic surgical consultation. Study importance: Musculoskeletal conditions are highly prevalent in the general population and often coexist with chronic diseases. However, little is documented about the overall health of this group. This study describes the health of these individuals, with particular emphasis on modifiable risk factors of chronic disease. Study type: A repeated measures longitudinal cohort study of individuals referred for orthopaedic consultation across three time points (2014, 2015 and 2016). Methods: This study was undertaken in the orthopaedic outpatient service of a public tertiary referral hospital in New South Wales, Australia. Participants were aged 18 years and older and were referred for and awaiting orthopaedic surgical consultation for a musculoskeletal condition (back, neck, hand or wrist pain, or hip or knee osteoarthritis). Measures included patient demographics, condition-specific indicators (e.g. pain, disability, quality of life [QoL]) and chronic disease risk factors (e.g., excess weight, smoking). Results: The mean age of participants was 57.7 years, and 7.3% identified as Aboriginal and/or Torres Strait Islander. Back (43.1%) and knee (35.0%) pain were the most prevalent conditions. At baseline (N = 1052), participants reported moderate pain (mean numerical pain rating scale score of 6.4, standard deviation [SD] 2.4) and QoL (Physical Component Score of 32.7, SD 10.7; Mental Component Score of 46.6, SD 13.3). Chronic disease risk factors were highly prevalent, with 74.6% of participants having three or more. For most measures, there were only small changes over time. Conclusion: Individuals with musculoskeletal conditions who are awaiting orthopaedic surgical consultation have a complex clinical picture and numerous chronic disease risk factors. Given the modifiable nature of many of these risk factors, identifying and addressing them before or while awaiting consultation may improve the health of these individuals.

Abstract	Background: Operative fixation for femoral metastatic bone disease is based on the principles of reducing pain and restoring function. Recent literature has proposed a number of prognostic models for appendicular metastatic bone disease. The aim of this study was to compare the accuracy of proposed soring systems in the setting of femoral metastatic bone disease in order to provide surgeons with information to determine the most appropriate scoring system in this setting. Methods: A retrospective cohort analysis of patients who underwent surgical management of femoral metastatic bone disease at a single institution were included. A pre-operative predicted survival for all 114 patients was retrospectively calculated utilising the revised Katagiri model, PathFx model, SSG score, Janssen nomogram, OPTModel and SPRING 13 nomogram. Univariate and multivariate Cox regression proportional hazard models were constructed to assess the role of prognostic variables in the patient group. Area under the receiver characteristics and Brier scores were calculated for each prognostic model from comparison of predicted survival and actual survival of patients to quantify the accuracy of each model. Results: For the femoral metastatic bone disease patients treated with surgical fixation, multivariate analysis demonstrated a number of pre-operative factors associated with survival in femoral metastatic bone disease, consistent with established literature. The OPTIModel demonstrated the highest accuracy at predicting 12-month (Area Under the Curve [AUC] = 0.79) and 24-month (AUC = 0.77) survival after surgical management. PathFx model was the most accurate at predicting 3-month survival (AUC = 0.70) and 6-month (AUC = 0.70) survival. The PathFx model was successfully externally validated in the femoral patient dataset for all time periods. Conclusions: Among six prognostic models assessed in the setting of femoral metastatic bone disease, the present study observed the most accurate model for 3-month, 6-month, 12-month and 24-month survival. The results of this study may be utilised by the treating surgical team to determine the most accurate model for the required time period and therefore improve decision-making in the care of patients with femoral metastatic bone disease.

Abstract	The core theme of the book is the importance of an independent state audit to ensure that the Executive is held accountable to Parliament. Instilling effective financial control and accountability for the use of public funds and the proper conduct of public business has been an incremental process that has taken centuries. This book provides a detailed history of the forces and personalities involved in the development of public sector audit, including the battles which extended well into the 20th century to establish a public sector audit that was constitutionally and in practice independent from the influence and control of the Executive. It identifies key themes that have emerged and re-emerged in these developments, and the challenges and obstacles faced and overcome over the years to arrive at today's modern audit framework and to establish current principles and practice in accountability to Parliament and the public.0The book charts the movement of public sector audit from a focus on the presentation and accuracy of accounts to the introduction of the added dimension of ensuring that funds are spent only for purposes approved by Parliament and that resources have been used efficiently, effectively and with economy. It explores the seminal relationships of the NAO and its predecessors with the Treasury, spending departments and the Public Accounts Committee; and it deals with the impact of major changes still taking place in the objectives, management and delivery of government programmes and services, including the growing involvement of outside agencies and the private sector. The book reviews the NAO's current achievements, continuing challenges, developments in the range and nature of its work, and future priorities. Importantly, it provides an authoritative source of reference for professionals and academics, while remaining accessible to readers with a more general interest in the developments and issues examined

Abstract	Background: Acutely infected total knee arthroplasty (TKA) is commonly treated with debridement, antibiotics, and implant retention (DAIR). There are no direct comparative studies to determine whether debridement should be performed open or arthroscopically for infected TKA. The aim of this study is to compare the outcomes of open vs arthroscopic debridement of infected TKAs. Methods: All patients at a university teaching hospital with an infected TKA treated with DAIR between 2002 and 2017 were analyzed. The primary outcome was successful treatment defined using international consensus criteria. Secondary outcomes included antibiotic suppression, prosthesis retention, mortality, postoperative range of motion, and length of stay. Clinical, laboratory, surgical, and antibiotic treatment data were collected. Propensity score matching was performed to control for selection bias. Results: DAIR was used in 141 patients. The initial DAIR procedure was open for 96 patients and arthroscopic for 45 patients. The success rate was 29% greater for open DAIR (45% open vs 16% arthroscopic; P < .001). After propensity score matching, this benefit was estimated to be 36% (95% confidence interval, 22%-50%; P < .0001). When those on antibiotic suppression were also considered successfully treated, open DAIR was still superior by 34% (95% confidence interval, 18%-51%; P < .0001). Conclusion: For infected TKA, open DAIR is a more successful index procedure compared with arthroscopic DAIR. Open DAIR remained more successful even when antibiotic suppression is considered successful treatment.
