People living with human immunodeficiency virus (HIV) are at increased risk of invasive pneumococcal disease (IPD). We assessed whether patients with invasive Streptococcus pneumoniae, in blood or cerebrospinal fluid, underwent HIV serology testing over a 5-year period. We found that only 39 inpatients out of 156 (25%) with IPD were tested for HIV and thus conclude that such testing is not being undertaken according to some guidelines in patients with IPD. Education and implementation strategies are required to increase testing.Copyright © 2021 Royal Australasian College of Physicians

Background: Cefiderocol, ceftazidime-avibactam, ceftolozane-tazobactam, intravenous fosfomycin and plazomicin represent potential carbapenem sparing agents for extended-spectrum-beta-lactamase or AmpC beta-lactamase producing Escherichia coli infection. However, available data is limited in predicting the volume of carbapenem therapy which could be substituted and real-world contraindications. Method(s): We determined the number of carbapenem days of therapy (DOT) which could be substituted and frequent contraindications accounting for antimicrobial susceptibility and site of infection in an unselected cohort with ceftriaxone-non-susceptible E. coli bacteremia at a single health network from 2015 to 2016. Individual patient data was used to calculate DOT and substitution for each agent. Result(s): There were 108 episodes of E. coli bacteremia resulting in 67.2 carbapenem DOT/100 patient-days of antimicrobial therapy administered. Ceftazidime-avibactam could be used to substitute 36.2 DOT/100 patient-days (54%) for inpatient definitive therapy, ceftolozane-tazobactam for 34.7 DOT/100 patient-days (52%), cefiderocol for 27.1 DOT/100 patient-days (40%), fosfomycin for 23.3 DOT /100 patient-days (35%) and plazomicin for 27.1 DOT/100 patient-days (40%). Non-urinary tract source of infection was the most frequent contraindication to fosfomycin (25), plazomicin (26) and cefiderocol (26). Use in outpatient parenteral antimicrobial therapy (OPAT) programs accounted for 40% of DOT, all of which could be substituted if stability data allowed for ceftazidime-avibactam and ceftolozane-tazobactam. Conclusion(s): All tested agents could be used to replace a significant volume of carbapenem therapy. Establishing stability of these agents for use in OPAT is required for maximizing their use as carbapenem sparing agents while randomized clinical data is awaited for some of these agents in resistant E. coli bacteremia.Copyright © 2020, The Author(s).

Background: Gonorrhoea is usually managed in community sexual health or general practice, but a proportion of cases present to hospital settings. In this study, we examined how gonorrhoea was managed through a large hospital network and what the implications may be for public health management. Method(s): A retrospective chart review was performed of the management of patients with Neisseria gonorrhoeae infection diagnosed at a large Australian healthcare network from January 2015 to May 2018. Documentation rates of five parameters of care were assessed: (1) the presence (or absence) of previous sexually transmissible infections (STIs); (2) recent travel; (3) discussion of HIV testing; (4) contact tracing; and (5) public health notification. Result(s): In all, 110 cases (48 male, 62 female) were analysed. Most cases were in the 15-39 years age group; 98 cases (89%) were symptomatic, and 12 (11%) were screening tests. The most common presenting syndromes were pelvic inflammatory disease (32%; 31/98 symptomatic cases), urethritis (26%; 25/98) and epididymo-orchitis (13%; 13/98). None of the five parameters assessed were documented in most cases. Documentation was most likely to occur in patients admitted to hospital. When HIV testing was performed, no new cases of HIV were identified. Conclusion(s): Infections with gonorrhoea present on a regular basis to hospital practice, but overall management is suboptimal. Automated prompts for other recommended tests, including HIV testing when testing for other sexually transmissible diseases is ordered, may improve management. Better awareness of best practice is needed, which can be facilitated with ongoing education. However, the greatest benefit is likely achieved by linking patients back to community-based services, which are best placed to provide ongoing long-term care.Copyright © CSIRO 2019 Open Access.
