Robotic-assisted unicompartmental knee arthroplasty is associated with earlier discharge from physiotherapy and reduced length-of-stay compared to conventional navigated techniques.

INTRODUCTION: Computer-assisted surgery (CAS) has been used to improve intraoperative accuracy to restore patient's anatomy and joint kinematics. It is not yet known whether robotic systems provide significant benefits over established navigation techniques. MATERIALS AND METHODS: Thirty-one patients underwent robotic-assisted UKA (RA-UKA) over a 14-month period. Length of operation, transfusion requirements, time to discharge, range-of-motion and analgesia requirements were compared to a similar cohort of 31 patients who had received UKA using computer-assisted surgery (CAS-UKA). RESULTS: All patients in the RA-UKA and CAS-UKA groups underwent surgery without conversion to conventional techniques. Both cohorts were similar apart from mean BMI (RA-UKA-group 28.5 vs 32.2; p < 0.05). There was a higher percentage of females in the CAS-UKA group (68% vs 45%, p = 0.12). Minor complication rates were the same in both groups (4/31, 12.9%). Mean operating time was longer in the RA-UKA group (104.8 vs 85.6 min; p < 0.001). No patients required post-operative transfusion in either group and there was no significant difference in haemoglobin level drop or analgesia requirements at any time point. Patients in the RA-UKA group achieved straight leg raise without lag sooner (23 vs 37.5 h; p = 0.004) and demonstrated increased range-of-motion on discharge (81.4° vs 64.5°; p < 0.001). Patients in the RA-UKA group were discharged from physiotherapy services earlier than the CAS-UKA group (42.5 vs 49 h; p = 0.02) and discharged from hospital significantly sooner (46 vs 74 h; p = 0.005). CONCLUSIONS: RA-UKA is safe and reproducible, comparable to traditional navigation. Patients undergoing RA-UKA achieve straight leg raise and discharge from physiotherapy sooner than with navigation alone. LEVEL OF EVIDENCE: III (Therapeutic) Retrospective Cohort Study.

An international cross-sectional survey of antimicrobial stewardship programmes in hospitals.

OBJECTIVES: To report the extent and components of global efforts in antimicrobial stewardship (AMS) in hospitals. METHODS: An Internet-based survey comprising 43 questions was disseminated worldwide in 2012. RESULTS: Responses were received from 660 hospitals in 67 countries: Africa, 44; Asia, 50; Europe, 361; North America, 72; Oceania, 30; and South and Central America, 103. National AMS standards existed in 52% of countries, 4% were planning them and 58% had an AMS programme. The main barriers to implementing AMS programmes were perceived to be a lack of funding or personnel, a lack of information technology and prescriber opposition. In hospitals with an existing AMS programme, AMS rounds existed in 64%; 81% restricted antimicrobials (carbapenems, 74.3%; quinolones, 64%; and cephalosporins, 58%); and 85% reported antimicrobial usage, with 55% linking data to resistance rates and 49% linking data to infection rates. Only 20% had electronic prescribing for all patients. A total of 89% of programmes educated their medical, nursing and pharmacy staff on AMS. Of the hospitals, 38% had formally reviewed their AMS programme: reductions were reported by 96% of hospitals for inappropriate prescribing, 86% for broad-spectrum antibiotic use, 80% for expenditure, 71% for healthcare-acquired infections, 65% for length of stay or mortality and 58% for bacterial resistance. CONCLUSIONS: The worldwide development and implementation of AMS programmes varies considerably. Our results should inform and encourage the further evaluation of this with a view to promoting a worldwide stewardship framework. The prospective measurement of well-defined outcomes of the impact of these programmes remains a significant challenge.

Causative organisms in revision total hip & knee arthroplasty for infection: Increasing multi-antibiotic resistance in coagulase-negative Staphylococcus and the implications for antibiotic prophylaxis.

BACKGROUND AND PURPOSE: Increasing resistance among post-operative Coagulase-negative Staphylococci (CNS) infections have been reported. We present our experience changing resistance patterns. METHODS: We examined microbiological results from hip and knee revisions from 2001 to 2010 and compared resistance to all Staphylococcus aureus (SA) and CNS cultured from regional pan-speciality sources, in order to examine the patterns of antibiotic resistance. MAIN FINDINGS: 72 revisions in 67 patients were included. The most common organisms were SA (36%) and CNS (35%). Resistance to methicillin was 72% for CNS versus 20% for SA and resistance to gentamicin was 40% for CNS versus 4% for SA. Among all regional (background pan-speciality) cultures SA resistance to methicillin fell from 32% to 16% from 2006 to 10 with no change in gentamicin resistance at 3%. During the same period resistance of CNS to methicillin and gentamicin increased from 63% to 70% and 32%-47% respectively. CONCLUSIONS: Resistance of CNS to both methicillin and gentamicin is higher than with SA and appears to be increasing. At least 32% of CNS and 4% of SA from infected TKRs/THRs were resistant to our current prophylaxis regime. These changing patterns of resistance may have implications for future antibiotic prophylaxis regimes.

Efficacy and safety of IV/PO moxifloxacin and IV piperacillin/tazobactam followed by PO amoxicillin/clavulanic acid in the treatment of diabetic foot infections: results of the RELIEF study.

OBJECTIVE: The aim was to compare the efficacy and safety of two antibiotic regimens in patients with diabetic foot infections (DFIs). METHODS: Data of a subset of patients enrolled in the RELIEF trial with DFIs requiring surgery and antibiotics were evaluated retrospectively. DFI was diagnosed on the basis of the modified Wagner, University of Texas, and PEDIS classification systems. Patients were randomized to receive either intravenous/oral moxifloxacin (MXF, N = 110) 400 mg q.d. or intravenous piperacillin/tazobactam 4.0/0.5 g t.d.s. followed by oral amoxicillin/clavulanate 875/125 mg b.d. (PIP/TAZ-AMC, N = 96), for 7-21 days until the end of treatment (EOT). The primary endpoint was clinical cure rates in the per-protocol (PP) population at the test-of-cure visit (TOC, 14-28 days after EOT). RESULTS: There were no significant differences between the demographic characteristics of PP patients in either treatment group. At TOC, MXF and PIP/TAZ-AMC had similar efficacy in both the PP and intent-to-treat (ITT) populations: MXF: 76.4 % versus PIP/TAZ-AMC: 78.1 %; 95 % confidence interval (CI) -14.5 %, 9.0 % in the PP population; MXF: 69.9 % versus PIP/TAZ-AMC: 69.1 %; 95 % CI -12.4 %, 12.1 % in the ITT population. The overall bacteriological success rates were similar in both treatment groups (MXF: 71.7 % versus PIP/TAZ-AMC: 71.8 %; 95 % CI -16.9 %, 10.7 %). A similar proportion of patients (ITT population) experienced any adverse events in both treatment groups (MXF: 30.9 % versus PIP/TAZ-AMC: 31.8 %, respectively). Death occurred in three MXF-treated patients and one PIP/TAZ-AMC-treated patient; these were unrelated to the study drugs. CONCLUSION: Moxifloxacin has shown favorable safety and efficacy profiles in DFI patients and could be an alternative antibiotic therapy in the management of DFI. CLINICAL TRIAL: NCT00402727.

Clinical and economic burden of community-acquired pneumonia among adults in Europe.

It is difficult to determine the impact of community-acquired pneumonia (CAP) in Europe, because precise data are scarce. Mortality attributable to CAP varies widely between European countries and with the site of patient management. This review analysed the clinical and economic burden, aetiology and resistance patterns of CAP in European adults. All primary articles reporting studies in Europe published from January 1990 to December 2007 addressing the clinical and economic burden of CAP in adults were included. A total of 2606 records were used to identify primary studies. CAP incidence varied by country, age and gender, and was higher in individuals aged ≥65 years and in men. Streptococcus pneumoniae was the most common agent isolated. Mortality varied from <1% to 48% and was associated with advanced age, co-morbid conditions and CAP severity. Antibiotic resistance was seen in all pathogens associated with CAP. There was an increase in antibiotic-resistant strains, but resistance was not related to mortality. CAP was associated with high rates of hospitalisation and length of hospital stay. The review showed that the clinical and economic burden of CAP in Europe is high. CAP has considerable long-term effects on quality of life, and long-term prognosis is worse in patients with pneumococcal pneumonia.

The effect of COVID-19 on a Major Trauma Network. An analysis of mechanism of injury pattern, referral load and operative case-mix.

PURPOSE: The aim of this study was to evaluate changes in both mechanism and diagnoses of injuries presenting to the orthopaedic department during this lockdown period, as well as to observe any changes in operative case-mix during this time. METHODS: A study period of twelve weeks following the introduction of the nationwide "lockdown period", March 23rd - June 14th, 2020 was identified and compared to the same time period in 2019 as a "baseline period". A retrospective analysis of all emergency orthopaedic referrals and surgical procedures performed during these time frames was undertaken. All data was collected and screened using the 'eTrauma' management platform (Open Medical, UK). The study included data from a five NHS Foundation Trusts within North West London. A total of 6695 referrals were included for analysis. RESULTS: The total number of referrals received during the lockdown period fell by 35.3% (n=2631) compared to the same period in 2019 (n=4064). Falls remained proportionally the most common mechanism of injury across all age groups in both time periods. The proportion sports related injuries compared to the overall number of injuries fell significantly during the lockdown period (p<0.001), however, the proportion of pushbike related accidents increased significantly (p<0.001). The total number of operations performed during the lockdown period fell by 38.8% (n=1046) during lockdown (n=1732). The proportion of patients undergoing operative intervention for Neck of Femur (NOF) and ankle fractures remained similar during both study periods. A more non-operative approach was seen in the management of wrist fractures, with 41.4% of injuries undergoing an operation during the lockdown period compared to 58.6% at baseline (p<0.001). CONCLUSION: In conclusion, the nationwide lockdown has led to a decrease in emergency orthopaedic referrals and procedure numbers. There has been a change in mechanism of injuries, with fewer sporting injuries, conversely, there has been an increase in the number of pushbike or scooter related injuries during the lockdown period. NOF fractures remained at similar levels to the previous year. There was a change in strategy for managing distal radius fractures with more fractures being treated non-operatively.

The impact of a managed care network on attendance, follow-up and treatment at a hepatitis C specialist centre.

Infection with the hepatitis C virus commonly occurs in patient groups who have difficulty accessing conventional medical care, reducing their chance of successful antiviral therapy. Managed care networks (MCNs) have been suggested as a mechanism of improving access to care; however, there is little evidence to support their use in patients with hepatitis C. The aim of this study was to evaluate the impact of a MCN for patients with hepatitis C. This was a retrospective cohort study of all individuals in our area who had received a positive hepatitis C antibody test between August 1994 and June 2008. The MCN introduced a new referral pathway, which included nonmedical referrals and outreach nurse-led clinics. These interventions were introduced in 2004 and evaluated in 2008. After the introduction of the MCN, the proportion of individuals who accessed care increased from 61% (280/430) to 82.4% (721/875). There was an increase in nonmedical referrals with 81 (18.3%) being directly referred from Drug Problem Services and 75 (17%) from the Prison Service. The changes to referral did not have a negative impact on treatment outcomes as the number who completed treatment increased from 66.1% (43/65) to 73.7% (98/133) and the sustained virological response increased from 50.7% (33/65) to 60.9% (81/133). This study provides evidence that the collaboration of health care professionals within a network can have a radical effect in improving access to care in a traditionally hard to reach population. This has been achieved with little additional resource, but rather working smarter with existing staff.

Predicting mortality in patients with community-acquired pneumonia and low CURB-65 scores.

Some patients classified as having non-severe community-acquired pneumonia (CAP) by CURB-65 subsequently die. The objective of this study was to identify risk factors for mortality in non-severe patients and to test how risk factors might be used. Patients who had a CURB-65 score of 0-2 on admission to hospital and were alive at 30 days were compared with those who died. Identified risk factors were included in new variations of CURB-65 and new management strategies. Age >65 years, blood urea >7 mmol/l, bilateral/multi-lobar appearance of the chest radiograph (CXR), social situation (living alone/no fixed abode or residential/nursing care) and temperature <36 degrees C were associated with mortality (p < 0.05). A two-step approach, with initial use of CURB-65 followed by the above non-CURB-65 criteria, increased the proportion of patients correctly classified as having severe CAP who subsequently died from 54/76 (71%, 95% confidence interval [CI] 61% to 81%) to 72/76 (95%, 95% CI 90% to 100%). The consideration of additional risk factors in a two-step approach can improve the stratification of mortality by CURB-65. Physicians should be cautious about managing patients with CAP as outpatients if they have a CURB-65 score of 1 (or more) and have at least one of the three additional risk factors identified.

Should we routinely perform a post-operative hemoglobin check following unicompartmental knee arthroplasty?

OBJECTIVES: To study the significance of checking post-operative hemoglobin and hematocrit following unicompartmental knee arthroplasty (UKA). SETTING: Single center. Multiple surgeons. DESIGN: Retrospective case series. Level of evidence IV. MATERIALS AND METHODS: Following institutional approval, a retrospective analysis of all patients undergoing UKA at our level one academic university hospital was conducted. Operative records of all patients undergoing primary UKA were reviewed between March 2016 and March 2019. Patients' pre-operative hemoglobin and hematocrit, BMI, co-morbidities, application of tourniquet, tourniquet time, administration of tranexamic acid, need for post-operative blood transfusion, hospital length of stay, complications, and re-admission were all recorded. Blood loss was estimated using the post-operative hematocrit. RESULTS: A total number of 155 patients were included. There were 70 females (45%) and 85 males (55%). The mean age was 66 ±â€¯10 years. Median pre-op blood volume was 4700 mLs (interquartile range (IQR); 4200-5100). Median blood loss was 600 mLs (IQR; 400-830). Mean pre-op hemoglobin was 135 ±â€¯14 g/L and mean post-op hemoglobin was 122 ±â€¯13 g/L. No patient had a post-op hemoglobin under 80 g/L (range 93-154). No patients in our study needed transfusion. CONCLUSION: The results of our study indicated that post-operative hemoglobin and hematocrit check proved unnecessary in all of our patients and could have been omitted from post-operative routines. We conclude that routine post UKA check of hemoglobin and hematocrit can be avoided and be saved for special circumstances depending on patient's physiology.

Achieving discharge within 24 h of robotic unicompartmental knee arthroplasty may be possible with appropriate patient selection and a multi-disciplinary team approach.

AIMS: There has been significant interest in day-case and rapid discharge pathways for unicompartmental knee replacements (UKR). Robotic-assisted surgery has the potential to improve surgical accuracy in UKR. However, to date there are no published studies reporting results of rapid-discharge pathways in patients receiving UKR using the NAVIO ◊ robotic system. METHODS: A retrospective analysis identified 19 patients who were safely discharged within 24 h following UKR using the NAVIO ◊ robotic system between June 2017 and October 2019. All patients went through a standardised UKR pathway protocol. Pre-operatively patients underwent education sessions and anaesthetic assessment, with selected patients undergoing occupational/physiotherapy assessment prior to surgery. All patients received a general anaesthetic with local anaesthetic infiltration prior to closure; nerve blocks were not used routinely. A multi-modal analgesic regime was utilised. Patients were discharged home once they were safe to mobilise on ward, had normal vital signs and pain was adequately controlled. Patients were discharged with outpatient physiotherapy referral and consultant follow up at 6 weeks. RESULTS: All patients were discharged within 24 h; there were no post-operative complications and no readmissions to hospital. The mean length of stay was 19.5 h (SD = 6.8), with patients seen twice on average by physiotherapy post-operatively. Active range of motion at 6 weeks was 105.8°, with all patients mobilising independently. The median 6-month post-operative Oxford Knee Score was 44 out of 48. CONCLUSION: This initial feasibility study suggests that patients may be safely discharged within 24 h of UKR using the NAVIO robotic system. Appropriate patient selection will ensure successful discharge. Further prospective studies are needed.

Predictors of extended length of stay after unicompartmental knee arthroplasty.

PURPOSE: To identify factors that independently predict extended length of stay after unicompartmental knee arthroplasty (UKA) surgery (defined as length of stay longer than 3 days), and to identify factors predicting early post-operative complications. METHODS: A retrospective analysis of all patients undergoing UKA from January 2016-January 2019 at our institution was performed. Clinical notes were reviewed to determine the following information: Patient age (years), gender, American Society of Anesthesiologists (ASA) grade, weight (kg), height (meters), body mass index (BMI), co-morbidities, indication for surgery, surgeon, surgical volume, surgical technique (navigated or patient-specific instrumentation), implant manufacturer, estimated blood loss (ml), application of tourniquet during the surgery, application of drain, hospital length of stay (days) and surgical complications. RESULTS: Multivariate regression analysis showed that ASA 3-4 vs. ASA 1-2 [OR 4.4 (CI; 1.8-10.8, p = 0.001)] and a history of cardiovascular disease [OR 2.8 (CI; 1.4-5.5), p = 0.004)] were significant independent predictors of prolonged length of stay. Hosmer-Lemeshow goodness of fit of the model showed a p-value of 0.214. Nagelkerke R-Square was 0.2. For complications, multivariate regression analysis showed that ASA 3-4 vs. ASA 1-2 [OR 5.8 (CI; 1.7-20.7)] and high BMI (BMI >30) [OR 4.3 (CI; 1.1-17.1)] were significant independent predictors of complications. Hosmer-Lemeshow goodness of fit was 0.89 and Nagelkerke R-Square was 0.2. Patients treated with robotics (Navio) techniques had shorter length of stay median 51 h (IQR; 29-96) when compared to other techniques 72 h (IQR; 52-96), p = 0.008. CONCLUSION: Based on the results of our study, high ASA grade (≥3) appears to be the most important factor excluding eligibility for fast-track UKA. Any number of co-morbidities may increase ASA, but in and of themselves, apart from a history of cardiovascular disease, they should not be seen as contraindications. Appropriate patient selection, technical tools and details during the surgery could facilitate fast track surgery.

MRSA as a cause of lung infection including airway infection, community-acquired pneumonia and hospital-acquired pneumonia.

Staphylococcus aureus has been recognised as a cause of community-acquired pneumonia, albeit uncommon, and an important cause of healthcare-associated (HA) pneumonia, including ventilator-associated pneumonia. Resistance of S. aureus to methicillin developed shortly after its introduction into clinical practice. Since then, methicillin-resistant S. aureus (MRSA) has predominantly been a feature of hospital-acquired, or latterly HA, infections as the boundaries became more blurred between the community and hospital environments. However, more recently true community-acquired (CA)-MRSA infections have been detected and are becoming increasingly common, especially in the USA. Europe has not been immune to the development of MRSA in healthcare settings and although the prevalence of CA-MRSA is currently relatively low, there is the risk of wider spread. These new CA-MRSA strains appear to behave differently to HA-MRSA strains. Although predominantly causing skin and soft tissue infections, mainly as boils and abscesses requiring drainage, life threatening invasive infections including necrotising pneumonia can also occur. This article summarises the pathogenesis and clinical presentations of MRSA-related lung infections.

Consultants in Scotland: survey of educational qualifications, experience and needs of Scottish consultants.

AIMS: To survey Scotland's NHS consultants regarding their teaching roles; educational qualifications/training; attitudes to educational qualifications; perceptions of health boards' attitudes to educational activities; usefulness of various educational courses and preferred delivery methods. METHODS: Postal questionnaire (n=3615). RESULTS: Sixty two percent response rate (n=2246). 98% had one or more roles in education/training. 54% spent more time in educational roles than job-plan allocations. 6% had educational qualifications. 30% rated educational qualifications valuable to their educational role; 21% to their career. 48% had not attended any educational training. 19% of respondents rated their health board as supportive of their educational activities. Respondents rated dealing with underperforming students (74%), dealing with challenging behaviour (63%), appraising students (63%), trainee assessment (61%) and feedback (58%) as the most useful topics. CONCLUSIONS: Scottish consultant involvement in educational activities is virtually universal but consultants perceive they need more time than allocated in job plans. Most consultants had no teaching qualifications. Nearly half had no formal training for educational activities. Educational qualifications were valued by a minority regarding both career development and educational activities. Increased access to staff development for teaching is required as NHS sources are not meeting the need for teacher training of consultant staff.

Implementation of antibiotic stewardship in different settings - results of an international survey.

Background: Antibiotic stewardship interventions are being implemented across different healthcare settings. We report the findings of a global survey of healthcare professionals on the implementation of antibiotic stewardship programmes. Methods: Learners of a Massive Online Open Course (MOOC) on antibiotic stewardship were invited to complete an online survey on the core available organisational resources for stewardship. The categorical variables were analysed using chi-squared test, and Likert questions were analysed using an ordinal regression model. The p-values were considered as two-tailed. Significance was set at p-value of < 0.05. Results: The response rate was 55% (505/920), from 53 countries. The responders were 36% (182) doctors, 26% (130) pharmacists, 18% (89) nurses and 20% (104) other (researchers, students and members of the public). Post-graduate training in infection management and stewardship was reported by 56% of doctors compared with 43% (OR 0.59, 95%CI 0.35-1.00) nurses and 35% (OR 0.39, 95%CI 0.24-0.62) of pharmacists. Hospitals were significantly (83% in teaching hospitals, 79% in regional hospitals, p = < 0.01) more likely to have antibiotic policies, when compared to primary care. A surveillance mechanism for antibiotic consumption was reported in 58% (104/178) of teaching hospitals and 62% (98/159) of regional hospitals. Antimicrobial resistance, patient needs, policy, peer influence and specialty level culture and practices were deemed important determinants for decision-making. Conclusion: Postgraduate training and support in antibiotic prescribing remains low amongst nurses and pharmacists. Whilst antibiotic policies and committees are established in most institutions, surveillance of antibiotic use is not. The impact of specialty level culture, and peer influence appears to be important factors of antibiotic prescribing.

Perceptions, attitudes, and practices of French junior physicians regarding antibiotic use and resistance.

OBJECTIVES: To assess the perceptions, attitudes, and practices of French junior physicians regarding antibiotic use and resistance, and then to identify the characteristics of junior physicians associated with appropriate practices of antibiotic use. METHOD: European junior physicians received an email invitation to complete a 49 item web questionnaire between September 2015 and January 2016. We present the French data. Multivariate regression models were used to identify the characteristics of junior physicians associated with appropriate prescription practices and with consideration of the antibiotic prescription consequences. RESULTS: The questionnaire was completed by 641 junior physicians: family medicine (37%), other medical specialties (e.g., pediatrics, internal medicine, neurology: 45%), surgical specialties (11%), and anesthesiology-intensive care specialty (7%). Most respondents (93%) declared being aware of the risk of bacterial resistance and 41% acknowledged prescribing antibiotics more often than necessary. Two factors were independently associated with appropriate prescription practices: a high perceived level of education on antibiotic use (OR=1.51; 95% CI [1.01-2.30]) and a medical specialty (OR=1.69; 95% CI [1.16-2.46]). Factors independently associated with taking into account adverse events of antibiotics were a good perceived knowledge of antibiotics (OR=3.71; 95% CI [2.09-6.61]), and a high perceived education level on antibiotics (OR=1.70; 95% CI [1.11-2.58]). CONCLUSION: Our data can help better define interventions targeting junior physicians in antibiotic stewardship programs.

Developing core elements and checklist items for global hospital antimicrobial stewardship programmes: a consensus approach.

OBJECTIVES: With increasing global interest in hospital antimicrobial stewardship (AMS) programmes, there is a strong demand for core elements of AMS to be clearly defined on the basis of principles of effectiveness and affordability. To date, efforts to identify such core elements have been limited to Europe, Australia, and North America. The aim of this study was to develop a set of core elements and their related checklist items for AMS programmes that should be present in all hospitals worldwide, regardless of resource availability. METHODS: A literature review was performed by searching Medline and relevant websites to retrieve a list of core elements and items that could have global relevance. These core elements and items were evaluated by an international group of AMS experts using a structured modified Delphi consensus procedure, using two-phased online in-depth questionnaires. RESULTS: The literature review identified seven core elements and their related 29 checklist items from 48 references. Fifteen experts from 13 countries in six continents participated in the consensus procedure. Ultimately, all seven core elements were retained, as well as 28 of the initial checklist items plus one that was newly suggested, all with ≥80% agreement; 20 elements and items were rephrased. CONCLUSIONS: This consensus on core elements for hospital AMS programmes is relevant to both high- and low-to-middle-income countries and could facilitate the development of national AMS stewardship guidelines and adoption by healthcare settings worldwide.

Microbiological and functional outcomes after open extremity fractures sustained overseas: The experience of a UK level I trauma centre.

BACKGROUND: Open extremity fractures carry a high risk of limb loss and poor functional outcomes. Transfer of extremity trauma patients from developing countries and areas of conflict adds further layers of complexity due to challenges in the delivery of adequate care. The combination of extensive injuries, transfer delays and complex microbiology presents unique challenges. METHODS: A retrospective review was conducted to analyse the surgical and microbiological themes of patients with open extremity fractures transferred from overseas to our institution (Imperial College NHS Trust) between January 2011 and January 2016. RESULTS: Twenty civilian patients with 21 open extremity fractures were referred to our unit from 11 different countries. All patients had poly-microbial wound contamination on initial surveillance cultures. Five patients (25%) underwent amputation depending on the extent of osseous injury; positive surveillance cultures did not preclude limb reconstruction, with seven patients undergoing complex reconstruction and eight undergoing simple reconstruction to achievewound coverage. Hundred percent of patients demonstrated infection-free fracture union on discharge. CONCLUSION: Patients with open extremity fractures transferred from overseas present the unique challenge of poly-microbial infection in addition to extensive traumatic wounds. Favourable outcomes can be achieved despite positive microbiological findings on tissue culture with adequate antimicrobial therapy. The decision to salvage the limb and the complexity of reconstruction used should be based on the chance of achieving meaningful functional recovery, mainly determined by the extent of bony injury. The complexity of reconstruction was based on the predicted long-term functionality of the salvaged limb.

Point prevalence survey of antibiotic use in Scottish hospitals utilising the Glasgow Antimicrobial Audit Tool (GAAT).

A point prevalence survey of antimicrobial prescribing was performed in 10 Scottish hospitals using the Glasgow Antimicrobial Audit Tool (GAAT). Appropriateness of the intravenous (IV) route was determined by an infectious diseases physician (IDP) and by a computerised algorithm. The IDP also estimated IV agent appropriateness. Each hospital was surveyed on a single day. Of 3826 patients surveyed, 1079 (28.3%) received an antibiotic, 381 (35.3%) intravenously; 197 (28.2%) orally treated had prior IV therapy. Median duration of IV was 4 days (IQR 2-7 days) and oral switch was 3.5 days (2-6). IV route was appropriate in 84% (IDP) and 84.8% (algorithm). Choice of agent was appropriate in 80% (IDP). Third-generation cephalosporins (3GC) (28.3%) were most frequent, followed by co-amoxiclav (20.2%), metronidazole (19.2%) and glycopeptides (18.6%). Regional differences were seen. The study shows it is possible to coordinate, collect and compare data from UK hospitals using the GAAT. Data may usefully inform local and national audit and support prescribing initiatives.

Infection control and management of MRSA: assessing the knowledge of staff in an acute hospital setting.

Much of the recent work in tackling meticillin-resistant Staphylococcus aureus (MRSA) has focused on hygiene in hospitals, but it is unclear how much hospital staff know about the treatment and management of patients who are colonized or infected with MRSA. The aim of this study was to assess the knowledge and perceived practice of staff regarding MRSA and its management in an acute hospital setting. A further aim was to determine what staff felt was needed in terms of information or education on the risks, management and treatment of MRSA. A questionnaire survey was carried out through group administration during a study day and by face-to-face interviews. Subjects included in the questionnaire were infection and colonization, treatment, and the availability of local support and advice. There were 174 responses, divided equally between doctors and nurses. Knowledge on many aspects of MRSA and its management was deficient, although the majority of participants who felt that they required additional information about MRSA acknowledged this. The survey confirmed that assumptions should not be made about adequate knowledge and expertise of staff in relation to MRSA. Gaps in awareness of aspects of care and management were highlighted and information and educational needs identified.
