Information Delay of Significant Bloodstream Isolates and Patient Mortality: A Retrospective Analysis of 6225 Adult Patients With Bloodstream Infections. Clin Infect Dis 2023; 77:680-686. [PMID: 37099685 DOI: 10.1093/cid/ciad243] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2023] [Revised: 04/08/2023] [Accepted: 04/19/2023] [Indexed: 04/28/2023] Open
Abstract
BACKGROUND Our aim in this study was to evaluate the clinical and prognostic impact of communicating microbiological information in real time for adult patients with bloodstream infections (BSIs). METHODS We retrospectively reviewed 6225 clinical episodes of bacteremia in a teaching hospital from January 2013 to December 2019. Bacteremia-associated mortality was compared when blood culture results were relayed to the infectious diseases specialist (IDS) in real time and periods when results were relayed the following morning. The impact of information availability using mortality at 30 days was used as the main outcome of the study. RESULTS The initial analysis (all microorganisms included) did not show an association of mortality and information delay to the IDS (odds ratio [OR], 1.18; 95% confidence interval [CI], .99-1.42). However, information delay of BSIs caused by fast-growing microorganisms such as Enterobacterales was associated with a significant increase in the odds of death at 30 days both in the univariate (OR, 1.76; 95% CI, 1.30-2.38) and multivariate analysis (OR, 2.22; 95% CI, 1.50-3.30). Similar results were found with mortality at 14 days and 7 days in the univariate (OR, 1.54; 95% CI, 1.08-2.20 and OR, 1.56; 95% CI, 1.03-2.37, respectively) and the multivariate analysis (OR, 2.05; 95% CI, 1.27-3.32 and OR, 1.92; 95% CI, 1.09-3.40, respectively). CONCLUSIONS Information delivered in real time has prognostic relevance and is likely to improve survival of patients with documented BSIs. Future studies should address the prognostic impact of adequate resource allocation (microbiologist/IDS with 24/7 coverage) in BSIs.

Kitaya S, Kakuta R, Kanamori H, Ohkoshi A, Ishii R, Nomura K, Tokuda K, Katori Y. Clinical and Epidemiological Characteristics of Bloodstream Infections in Head and Neck Cancer Patients: A Decadal Observational Study. J Clin Med 2022; 11:jcm11164820. [PMID: 36013061 PMCID: PMC9409783 DOI: 10.3390/jcm11164820] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2022] [Revised: 08/10/2022] [Accepted: 08/16/2022] [Indexed: 11/16/2022] Open
Abstract
This retrospective study aims to describe the clinico-epidemiological characteristics of bloodstream infections (BSIs) and the risk factors in patients with head and neck cancer (n = 227) treated at the Department of Otolaryngology, Head and Neck Surgery, Tohoku University Hospital between April 2011 and March 2021. Overall, 23.3% of blood cultures were positive. In the culture-positive group, catheter-related bloodstream infections (CRBSIs) were the most common (38.8%), followed by respiratory tract infections (19.4%), and catheter-associated urinary tract infections (6.0%). Methicillin-resistant Staphylococcus aureus (26.9%), Staphylococcus epidermidis (17.9%), and Pseudomonas aeruginosa (10.4%) infections were common. The most frequent treatment for head and neck cancer was surgery (23.9%), followed by treatment interval or palliative care (19.4%), and single radiotherapy (13.4%). The 30-day mortality rate was significantly higher in the BSI than in the non-BSI group (10.4% vs. 1.8%, respectively). CRBSIs are the most frequent source of BSIs in patients with head and neck cancer. In conclusion, central venous catheters or port insertion should be used for a short period to prevent CRBSIs. The risk of developing BSI should be considered in patients with pneumonia. Understanding the epidemiology of BSIs is crucial for diagnosing, preventing, and controlling infections in patients with head and neck cancer.
