Hand Hygiene Knowledge and Hand Dirtiness Assessment to Inform Alcohol-Based Hand Rub Appropriateness in Community Settings in Uganda and Kenya.

During the coronavirus disease 2019 pandemic, alcohol-based hand rub (ABHR) availability and use increased as a prevention measure. ABHR is a convenient, effective way to kill microbes on hands but is hampered by the presence of organic material, whereas handwashing with water and soap (HWWS) can physically remove microbes and dirt. Although ABHR is preferred in most health care settings, the suitability of ABHR use in community settings has not been measured. We compared characteristics between community members and health care personnel (HCP) to inform considerations for promoting ABHR in community settings. We included data from community locations and health care facilities in Kenya and Uganda collected between 2021 and 2022. Hand dirtiness swabs were measured using the Quantitative Personal Hygiene Assessment Tool (qPHAT), a visual scale where 0 is very visibly dirty and 10 is no visible dirt. Participants were also asked about the appropriate method to use when hands were visibly dirty. Hand swabs were collected from HCP and community members. Both groups had median qPHAT scores of five. Neither the adjusted odds of having a qPHAT score less than or equal to five (1.4, 95% CI: 0.8-2.2) nor the adjusted odds of responding correctly to the knowledge question (0.8, 95% CI: 0.4-1.4) differed significantly by setting. People in community settings may, therefore, have comparable hand dirtiness and knowledge of appropriate hand hygiene practices to use ABHR as a HWWS complement. Further investigation into guidance and use of supportive messaging should be considered as completed elsewhere.
