Table 1. Parameter estimates used in the model of CPKP transmission.

Parameter Symbol Value used inthe model Note
Number of beds B 30
Number of HCWs 24 Total daily number
Number of nursing staff 10 Total daily number
Discharge rate for uncolonized patients (/day) μμ 1/10.3 1/duration of stay of uncolonized patients
Discharge rate for colonized patients (/day) μc 1/22.9 1/duration of stay of colonized patients
Admission rate (/day) λ 5.0–8.7 Inline graphic using monthly estimates of bed occupancy
Colonization prevalence on admission (%) φ 0%–4.9% Monthly estimates
Per capita contact rate (/patient/HCW/day) α 1.4
Probability of a patient becoming colonizedduring contact with contaminated HCW bp Estimated by the model
Probability of a HCW becoming contaminated during contact with colonized patient bh 21.4% CPKP was isolated from the hands of HCWs in 15 out of 70 contacts with colonized patients
Decontamination rate of HCWs (/day) μh 24 1/duration of contamination where duration is assumed 1 hour (1hour = 1/24 days)
Hand washing compliance p 21%
