Table 2 Estimated model parameters for Model 5

From: Mathematical modelling of vancomycin-resistant enterococci transmission during passive surveillance and active surveillance with contact isolation highlights the need to identify and address the source of acquisition

Parameters Symbol (unit) Median values (95% credible intervals)
Background acquisition coefficient β0 (×10− 4) (/susceptible/day) 76 (26 to 130)
Cross-transmission coefficient in patients who were not contact isolated β1 (×10− 4) (/VRE colonised or infected patient that was not contact isolated/susceptible/day) 4.9 (0.049 to 33)
Cross-transmission coefficient in patients who were contact isolated β2 (×10−4) (/VRE colonised or infected patient that was contact isolated/susceptible/day) 1.7 (0.012 to 82)
Probability of detection for passive surveillance λ 0.044 (0.016 to 0.14)
Ratio of VRE transmission with contact isolation versus without contact isolation 0.33 (0.050 to 1.22)
Proportion of VRE colonisation/infection that was acquired via cross-transmission (%) 0.17 (0.0015–0.72)
