The relationship between clinical outcomes and empirical antibiotic therapy in patients with community-onset Gram-negative bloodstream infections: a cohort study from a large teaching hospital.

Antibiotic-resistant Gram-negative bacteraemias (GNB) are increasing in incidence. We aimed to investigate the impact of empirical antibiotic therapy on clinical outcomes by carrying out an observational 6-year cohort study of patients at a teaching hospital with community-onset Escherichia coli bacteraemia (ECB), Klebsiella pneumoniae bacteraemia (KPB) and Pseudomonas aeruginosa bacteraemia (PsAB). Antibiotic therapy was considered concordant if the organism was sensitive in vitro and discordant if resistant. We estimated the association between concordant vs. discordant empirical antibiotic therapy on odds of in-hospital death and ICU admission for KPB and ECB. Of 1380 patients, 1103 (79.9%) had ECB, 189 (13.7%) KPB and 88 (6.4%) PsAB. Discordant therapy was not associated with increased odds of either outcome. For ECB, severe illness and non-urinary source were associated with increased odds of both outcomes (OR of in-hospital death for non-urinary source 3.21, 95% CI 1.73-5.97). For KPB, discordant therapy was associated with in-hospital death on univariable but not multivariable analysis. Illness severity was associated with increased odds of both outcomes. These findings suggest broadening of therapy for low-risk patients with community-onset GNB is not warranted. Future research should focus on the relationship between patient outcomes, clinical factors, infection focus and causative organism and resistance profile.

Cross-sectional study of Ebola virus disease preparedness among National Health Service hospital trusts in England.

BACKGROUND: The largest outbreak of Ebola virus disease (EVD) is ongoing in West Africa. Air-travel data indicate that outside Africa, the UK is among the countries at greatest risk of importing a case of EVD. Hospitals in England were therefore instructed to prepare for the assessment and early management of suspected cases. However, the response of hospitals across England is undetermined. AIM: To evaluate the readiness of acute hospitals in England, and to describe the challenges experienced in preparing for suspected cases of EVD. METHODS: A cross-sectional study using semi-structured telephone interviews and online surveys of all acute National Health Service (NHS) hospital trusts in England (hospital trusts are the vehicle by which one or more NHS hospitals in a geographical area are managed). FINDINGS: In total, 112 hospital trusts completed the survey. All interviewed hospital trusts reported undertaking preparedness activities for suspected cases of EVD, and 97% reported that they were ready to assess suspected cases. Most hospital trusts had considered scenarios in accident & emergency (97%). However, fewer hospital trusts had considered specific obstetric (61%) and paediatric scenarios (79%), the provision of ventilatory and renal support (75%), or resuscitation in the event of cardiorespiratory arrest (56%). Thirty-four hospital trusts reported issues with timely access to category A couriers for sample transportation. Challenges included the choice, use and procurement of personal protective equipment (71%), national guidance interpretation (62%) and resource allocation/management support (38%). CONCLUSION: English hospital trusts have engaged well with EVD preparedness. Although subsequent national guidance has addressed some issues identified in this study, there remains further scope for improvement, particularly in a practical direction, for acute care services encountering suspected cases of EVD.
