Applying Human Factors to Reduce Healthcare-Associated Infections Caused by Face Touching

Canada is currently facing a critical healthcare worker (HCW) shortage, in part resulting from absenteeism due to healthcare-associated infection (HAI). HCWs are at greater risk of infection and are among the most common sources of HAI transmission. Face touching is a behaviour that HCWs engage in on average 20-23 times per hour, and is one way for HCWs to infect themselves. While personal protective equipment (e.g., face masks) has been found to decrease face touching, the behaviour still occurs. We conducted a literature review on face touching, previously proposed solutions for addressing face touching, and the applications of human factors in mitigating face touching behaviours. We also conducted a pilot study of semi-structured interviews with three HCWs using the Lead User method to understand their needs and explore how best to decrease face touching, which resulted in several suggested interventions for reducing face touching.
