How and why do healthcare workers use gloves in two Norwegian nursing homes?

BACKGROUND: Incorrect glove use can cause cross-contamination and healthcare-associated infections. Previous research has identified reasons for this, such as lack of indication, improper changing, and poor hand hygiene post use. Limited research has investigated the reasons behind healthcare workers' glove usage. AIM: To develop an in-depth understanding of healthcare worker (HCW) attitudes and perceptions of glove use and to explore barriers and facilitators as well as compliance with national guidelines. METHODS: A small-scale convergent-parallel mixed methods study design consisting of observations with focus group interviews (FGIs) by using the Systems Engineering Initiative for Patient Safety model (SEIPS). The study was conducted at two Norwegian municipal nursing homes in Oslo for two weeks in January-February 2023. FINDINGS: Out of 73 observations, gloves were used in 67 episodes, not worn even if indicated in six observations, and were overused 16 times (21.9%). Lack of hand hygiene after glove removal was observed in 36 out of 67 instances (53.7%). Two FGIs disclosed that glove usage decisions are shaped by habits, knowledge, experience, and emotions linked to patient requirements, tasks, and glove type. Double gloves were used for self-protection and efficiency. Availability of gloves was a facilitator, while poor glove quality posed a barrier. CONCLUSION: Despite HCWs' knowledge of glove guidelines, their attitudes did not consistently ensure compliance. This study underscores the need for targeted interventions to improve hand hygiene after glove removal, urging awareness of glove overuse to reduce infections, protect HCWs' skin, and promote sustainability.

Development of a method to measure bacterial transfer from hands.

A method was developed to investigate the transfer of bacteria from the hands of healthcare workers (HCWs). The method involved standardised hand contact between the HCW and a recipient wearing sterile gloves, followed by sampling of the bare hands of the HCW and the gloved hands of the recipient by the glove juice method. The duration of contact, degree of friction and dryness of the hands could be varied. We investigated the applicability of the method for measuring transfer from hands artificially contaminated with Escherichia coli as well as from naturally contaminated hands following a 30s contact time with moderate friction and dry hands. Only a small proportion of bacteria on donor hands was recovered from the recipient: 0.15% for E. coli and 0.07% for natural hand flora. A smaller proportion of E. coli was recovered from bare skin compared with gloves, suggesting reduced survival of bacteria as a result of contact with natural skin. We suggest that these data are clinically relevant, and may indicate low transfer of bacteria during short contact with dry hands. This method is suitable to investigate the effect of potential risk factors for ineffective hand hygiene and the effect of hand hygiene procedures on contact transmission in clinical studies with large numbers of HCWs.
