A space-time model for carbapenemase-producing Klebsiella pneumoniae (KPC) cluster quantification in a high-complexity hospital

Epidemiol Infect. 2015 Sep;143(12):2648-52. doi: 10.1017/S0950268814003811. Epub 2015 Jan 12.

Abstract

A retrospective space-time permutation model with non-Euclidean distance criteria was applied within a high-complexity hospital setting to quantitatively explore cluster patterns of 273 patients infected with or colonized by carbapenemase-producing Klebsiella pneumoniae during 4 years. Results were compared to standard nosocomial active-surveillance methods. Two clusters were identified in the period, suggesting that space-time strategies for cluster quantification within confined environments may be useful.

Keywords: KPC; outbreaks; space–time; surveillance.
