ItemNo Preview AvailableThe Australasian Society for Infectious Diseases guidelines for the diagnosis, management and prevention of infections in recently arrived refugees: an abridged outline(WILEY, 2009-04-20)About 13,000 refugees are currently accepted for migration into Australia each year, many of whom have spent protracted periods living in extremely disadvantaged circumstances. As a result, medical practitioners are increasingly managing recently arrived refugees with acute and chronic infectious diseases. The Australasian Society for Infectious Diseases has formulated guidelines for the diagnosis, management and prevention of infection in newly arrived refugees. This article is an abridged version of the guidelines, which are available in full at . All refugees should be offered a comprehensive health assessment, ideally within 1 month of arrival in Australia, that includes screening for and treatment of tuberculosis, malaria, blood-borne viral infections, schistosomiasis, helminth infection, sexually transmitted infections, and other infections (eg, Helicobacter pylori) as indicated by clinical assessment; and assessment of immunisation status, and catch-up immunisations where appropriate. The assessment can be undertaken by a general practitioner or within a multidisciplinary refugee health clinic, with use of an appropriate interpreter when required. The initial assessment should take place over at least two visits: the first for initial assessment and investigation and the second for review of results and treatment or referral.

ItemEmpiric antibiotic regimens for neonatal sepsis in Australian and New Zealand neonatal intensive care units(WILEY, 2017-07)AIM: Neonatal sepsis remains an important cause of morbidity and mortality, and requires prompt empiric treatment. However, only a minority of babies who receive antibiotics for suspected sepsis have an infection. Antimicrobial exposure in infancy has important short- and long-term consequences. There is no consensus regarding empirical antimicrobial regimens. METHODS: The study included a survey of empiric antimicrobial regimens in all tertiary neonatal intensive care units in Australia and New Zealand in 2013-2014. RESULTS: All 27 units responded. For early-onset sepsis, all units used a combination of gentamicin with either penicillin or ampicillin. For late-onset sepsis, the frequency of units using empiric vancomycin (41%) versus empiric flucloxacillin (48%) was similar. Gestational age or the presence of a central venous catheter had little influence on using vancomycin instead of flucloxacillin. For late-onset sepsis with meningitis there was marked variation in antimicrobial combinations, with 15 different regimens described. A total of 93% used a cefotaxime-based regimen, either as monotherapy (22%) or combined with a second (22%) or third (48%) agent. For suspected necrotising enterocolitis, 89% used an aminoglycoside, metronidazole and a penicillin. Historical outbreaks of multi-resistant organisms exerted long-term influence over regimen choice. CONCLUSIONS: There was limited use of broad-spectrum agents such as carbapenems or third-generation cephalosporins. In this region with low methicillin-resistant Staphylococcus aureus prevalence, empiric vancomycin use was common, selected for activity against coagulase-negative staphylococci. Empiric vancomycin is rarely necessary because coagulase-negative staphylococci are often contaminants and sepsis is rarely fulminant, occurring almost exclusively in extremely low birthweight infants. Implementation of appropriate, local antimicrobial policies is crucial to minimise antimicrobial exposure in this vulnerable population and halt the development of antimicrobial resistance.

ItemAntenatal pertussis vaccination: Are we implementing best evidence into practice?(WILEY, 2016-12)Maternal immunisation is the most effective strategy to reduce infant morbidity and mortality from pertussis infection, and is now standard of care in many countries, including Australia. However, uptake cannot be guaranteed unless the barriers to implementing programs locally are understood. Education and resources for antenatal care providers, embedding vaccination within antenatal care, and provision of culturally appropriate information for pregnant women are integral to a successful antenatal vaccination program.

ItemPositive predictive value of ICD-10 codes to detect anaphylaxis due to vaccination: A validation study(WILEY, 2019-10)PURPOSE: To validate the use of selected International Classification of Disease Codes 10th revision (ICD-10) to predict (positive predictive value) anaphylaxis due to vaccination using emergency department (ED) data. METHODS: We conducted a retrospective study using ED encounter data from a large tertiary-care teaching hospital, Monash Medical Centre, Melbourne, Australia. We searched all ED encounters potentially due to anaphylaxis after vaccination, between 1 January 2010 and 31 December 2018, using ICD-10-CM codes T80.5, T80.6, T88.1, T88.6, and T78.2. Health records of potential cases were examined to determine if they met the Brighton Collaboration (BC) criteria for anaphylaxis. We calculated the PPV to evaluate the accuracy of the selected ICD-10-CM codes in predicting anaphylaxis due to vaccination. RESULTS: Of the 69 health records identified and reviewed, 29 (42.2%) met the criteria for anaphylaxis regardless of the cause, and 24.6% (17/69) of records were confirmed as anaphylaxis triggered by vaccination (low positive predictive value). However, of the 23 records identified using ICD-10-CM code T80.5, 22 were classified as anaphylaxis cases regardless of the cause, and 12 were anaphylaxis due to vaccination cases giving PPV of 95.7% and 52.2%, respectively. CONCLUSIONS: Given that there is no specific ICD-10-CM code for anaphylaxis due to vaccination, ICD-10-CM code T80.5 may be suitable to monitor anaphylaxis due to vaccination in the ED setting. The current study was conducted at a single centre and needs to be confirmed by future multicentre studies.

ItemA study comparing the practice of Australian maternity care providers in relation to maternal immunisation(WILEY, 2019-06)BACKGROUND: Women's decisions regarding vaccination during pregnancy are heavily influenced by maternity care provider (MCP) recommendations. Understanding why MCPs may not recommend vaccination is central to improving vaccination rates. AIMS: To examine the knowledge, attitudes and practice of Australian MCPs to maternal vaccination. METHODS: We surveyed obstetricians, midwives and general practitioners (GPs) between September and November 2016. Providers were asked about their knowledge and current practice, and about their perceived roles in discussing and administering maternal vaccinations. RESULTS: Eight hundred and seventy surveys were completed. Each MCP group believed they had the primary responsibility for discussing vaccinations but all groups perceived GPs as primarily responsible for administering vaccines. More midwives had concerns about safety (21/129, 16%) than obstetricians (9/359, 3%) and GPs (7/326, 2%) (P < 0.001). Overall, 83% of MCPs recommended diphtheria-tetanus-acellular pertussis vaccination (dTpa) and 78% inactivated influenza vaccination (IIV) according to guidelines, with no differences between groups. Overall 77% provided dTpa onsite (GPs 99%, midwives 70%, obstetricians 60%, P < 0.001) and 71% provided IIV (GPs 99%, midwives 48%, obstetricians 54%, P < 0.001). Factors associated with recommending vaccination in accordance with guidelines and providing vaccination onsite were similar across groups: personal history of vaccination, confidence in vaccine knowledge, and awareness of recommendations for and belief in the safety of maternal dTpa. CONCLUSIONS: Among MCPs, the rates of recommending and providing maternal vaccination were higher than previously reported. Further improvements might be expected with increased awareness of guidelines, further education around vaccine safety, and by changing perceptions of the role of obstetricians and midwives in providing maternal vaccinations.

ItemAntimicrobial prescribing for children in primary care(WILEY, 2019-01)AIM: To describe the patterns of antimicrobial prescribing in general practice for children aged ≤18 years. METHODS: This is a review of routinely collected patient data extracted from computerised medical records from 39 general practices in eastern metropolitan Melbourne over a 5-year period, 2010-2014. MAIN OUTCOME MEASURES: Proportion of paediatric consultations resulting in antibiotic prescription, type and frequency of antibiotics prescribed, antibiotic prescribing stratified by age, reason for indication and inter-practice variation. RESULTS: There were 744 883 consultations for 89 983 individual paediatric patients and 85 913 prescriptions for antibiotics during the study period. Of these antibiotic prescriptions, 75 410 were associated with a consultation, and 10 503 (12.2% of all prescriptions) had no associated consultation in the data. On average, one in five individual children was prescribed an antibiotic each year. The most commonly prescribed antibiotics were cephalexin, amoxycillin/clavulanate, cefaclor, phenoxymethylpenicillin and roxithromycin. Less than 3% of all prescriptions were for amoxycillin. Prescribing of cefaclor and roxithromycin decreased, although cefaclor remained the third most common antibiotic choice for general practitioners. Peaks in prescribing were noted over winter months. Reason for prescription was not recorded for 82% of prescriptions. The frequency of antibiotic prescription per consultation varied substantially (2.1-19.7%) between general practitioner clinics. Overall, antibiotic prescribing decreased by 2.3% over the 5-year period. CONCLUSIONS: This study provides a focused examination of antibiotic prescribing practices for children in Australian general practice. More information is required to better understand specific prescribing practices in children, including the low frequency of amoxycillin prescription and ongoing prescription of cefaclor.

ItemSeroresponses and safety of 13-valent pneumococcal conjugate vaccination in kidney transplant recipients(WILEY, 2018-04)BACKGROUND: Conjugated pneumococcal vaccine is recommended for kidney transplant recipients, however, their immunogenicity and potential to trigger allograft rejection though generation of de novo anti-human leukocyte antigen antibodies has not been well studied. METHODS: Clinically stable kidney transplant recipients participated in a prospective cohort study and received a single dose of 13-valent conjugate pneumococcal vaccine. Anti-pneumococcal IgG was measured for the 13 vaccine serotypes pre and post vaccination and functional anti-pneumococcal IgG for 4 serotypes post vaccination. Anti-human leukocyte antigen antibodies antibodies were measured before and after vaccination. Kidney transplant recipients were followed clinically for 12 months for episodes of allograft rejection or invasive pneumococcal disease. RESULTS: Forty-five kidney transplant recipients participated. Median days between pre and post vaccination serology was 27 (range 21-59). Post vaccination, there was a median 1.1 to 1.7-fold increase in anti-pneumococcal IgG antibody concentrations for all 13 serotypes. Kidney transplant recipients displayed a functional antibody titer ≥1:8 for a median of 3 of the 4 serotypes. Post vaccination, there were no de novo anti-human leukocyte antigen antibodies, no episodes of biopsy proven rejection or invasive pneumococcal disease. CONCLUSION: A single dose of 13-valent conjugate pneumococcal vaccine elicits increased titers and breadth of functional anti-pneumococcal antibodies in kidney transplant recipients without stimulating rejection or donor-specific antibodies.
