Transmission thresholds for the spread of infections in healthcare facilities
Fig 3
Scatterplot of facility basic reproduction number vs. length of stay (LOS) distribution statistics.
Calculations of the facility reproduction number, , for Model 3 with the following fixed values calibrated to pre-intervention CRE data in long-term acute care hospitals (Table 3): transmission rate
per day, clinical detection rate
per day, colonization clearance rate
per day, and contact precaution effectiveness
. The dots represent
results for 1000 sets of values for each of the four parameters governing the mixed exponential–gamma length of stay distribution, drawn from four independent uniform distributions ranging from 60% to 140% of the calibrated values in Table 3. Each subplot displays the same 1000
results, plotted against different statistics of the length of stay distribution for each set of length-of-stay parameters.
