| Title: How human strategic behavior updating in evolutionary games: a guide to better in-service training program | |
| Abstract:
Hand hygiene compliance is the most significant, modifiable cause of hospital-acquired infections (HAIs), prolonging the duration of stay in hospitals, and then increased financial burden. The main driver for the high level of infection transmission is that self-interested nurses do not conduct hand-washing consistently but strategically and therefore, the compliance rate is generally low. To combat HAIs, hospitals have invested resources in in-service training program to improve nurses’ hand hygiene adherence. In this speech, we study the impact of self-interested nurses on the ineffectiveness in in-service education to improve HAIs. In order to capture both infection transmission dynamics and strategic behavior, we draw on an existing body of literature that has sought to combine epidemiologic compartmental models of infection transmission with strategic behavior. Further, I will present our model across a wide space of different parameter values meant to capture an infection transmission dynamics and formulate nurses' strategic behavior as an evolutionary game. Behavioral change in a workplace does not occur overnight. The result of our model suggests that there are three motivations behind nurses' hand-washing compliance rate. Given a policy, it takes time for group behavior to converge to equilibrium, through which we are able to explain “why don’t interventions work as expected?”
