General practitioner and nurse prescriber experiences of prescribing antibiotics for respiratory tract infections in UK primary care out-of-hours services (the UNITE study).
Interventions are needed to reduce unnecessary antibiotic prescribing for respiratory tract infections (RTIs). Although community antibiotic prescribing appears to be decreasing in the UK, figures for out-of-hours (OOH) prescribing have substantially increased. Understanding the factors influencing prescribing in OOH and any perceived differences between general practitioner (GP) and nurse prescriber (NP) prescribing habits may enable the development of tailored interventions promoting optimal prescribing in this setting. ⋯ Environmental and social factors in OOH services and a mixed healthcare workforce provide unique influences on antibiotic prescribing for RTIs, which would need to be considered in tailoring interventions that promote prudent antibiotic prescribing in OOH services.

ReviewTreatment of infections caused by multidrug-resistant Gram-negative bacteria: report of the British Society for Antimicrobial Chemotherapy/Healthcare Infection Society/British Infection Association Joint Working Party.
The Working Party makes more than 100 tabulated recommendations in antimicrobial prescribing for the treatment of infections caused by multidrug-resistant (MDR) Gram-negative bacteria (GNB) and suggest further research, and algorithms for hospital and community antimicrobial usage in urinary infection. The international definition of MDR is complex, unsatisfactory and hinders the setting and monitoring of improvement programmes. We give a new definition of multiresistance. ⋯ The diagnosis and treatment of both presumptive and confirmed cases of infection by GNB should be improved. This guidance, with infection control to arrest increases in MDR, should be used to improve the outcome of infections with such strains. Anticipated users include medical, scientific, nursing, antimicrobial pharmacy and paramedical staff where they can be adapted for local use.

T2 magnetic resonance for the diagnosis of bloodstream infections: charting a path forward.
We discuss four studies in this issue of the Journal of Antimicrobial Chemotherapy that describe experience with T2 magnetic resonance (T2MR) nanodiagnostics for Candida and bacterial bloodstream infections, in the context of the T2MR literature. T2Candida and T2Bacteria panels use a dedicated instrument to detect amplified DNA from microbial cells directly in whole blood. T2Candida gives positive or negative results for C. albicans/C. tropicalis, C. glabrata/C. krusei, and C. parapsilosis. ⋯ Finally, a study from a hospital in Rome provides the first clinical data for T2Bacteria: sensitivity and specificity were 89% and 98%, respectively, among patients with positive blood cultures for bacteria detected by the panel, or fulfilling criteria for infection. We conclude that T2MR diagnostics are promising both for detecting bloodstream infections due to Candida and bacteria, and for providing prognostic information. More studies that present real-world performance data are needed.
