Background: Hand hygiene compliance (HHC) can be influenced by behavioural determinants, but knowledge on this remains scarce. The Capability, Opportunity, Motivation-Behaviour (COM-B) hand hygiene questionnaire was developed by Lydon et al. to gain insight into self-reported behavioural determinants and self-reported HHC., Aims: To determine the validity of self-reported HHC using the COM-B questionnaire; and investigate the influence of self-reported behavioural determinants on observed HHC, taking environmental determinants into account., Methods: This was a cross-sectional study, from September to November 2019, in nine hospitals in the Netherlands. Healthcare workers (HCWs) completed the COM-B questionnaire, and direct hand hygiene observations were performed. In addition, information on environmental determinants (workload, ward category, hospital type and ward infrastructure) was collected. Validity of self-reported HHC was determined using the intraclass correlation coefficient (ICC). Univariable and multi-variable regression analyses were performed to investigate the relationship between behavioural and environmental determinants and observed HHC., Findings: The ICC showed no association between self-reported HHC and observed HHC [0.04, 95% CI -0.14 to 0.21]. In univariable regression analyses, ward category and the opportunity and motivation subscales were significantly associated with observed HHC. In multi-variable regression analysis, only ward category and the motivation subscale remained significant., Conclusion: Self-reported HHC is not a valid substitute for direct hand hygiene observations. Motivation (behavioural determinant) was significantly associated with HCC, while almost none of the environmental determinants had an effect on observed HHC. In further development of hand hygiene interventions, increasing the intrinsic motivation of HCWs should receive extra attention., (Copyright © 2023 The Authors. Published by Elsevier Ltd..

Background: Observing hand hygiene compliance (HHC) among non-sterile healthcare workers (HCWs) in the operating theatre (OT) is challenging as there are no tailored protocols or observation tools., Aim: To develop and test a hand hygiene protocol tailored to non-sterile HCWs in the OT., Methods: In this prospective observational study, nine hospitals in the Rotterdam-Rijnmond region provided input on a draft protocol on hand hygiene in the OT, resulting in a new consensus protocol for the region. An observation tool based on the protocol was developed and tested. HHC rates with 95% confidence intervals (CI) were calculated by type of hospital and type of HCW., Findings: The protocol has three sections: (1) written general hand hygiene rules; (2) written hand hygiene rules specific for anaesthesia and surgery; and (3) visual representation of the OT, divided into four hand hygiene areas. Hand hygiene should be applied when changing area. Average HHC of 48.0% (95% CI 45.2-61.2%) was observed in OTs across all hospitals. HHC was highest in the two specialized hospitals (64.0%, 95% CI 30.6-89.8%; 76.7%, 95% CI 62.8-84.5%) and lowest in the academic teaching hospital (23.1%, 95% CI 0.0-45.8%). In terms of type of HCW, HHC was lowest among anaesthesiologists (31.6%, 95% CI 19.2-62.4%) and highest among OT assistants (57.4%, 95% CI 50.1-78.2%)., Conclusion: This uniform way of observing HHC in the OT enables evaluation of the effectiveness of interventions in the OT and facilitates friendly competition. In the Rotterdam-Rijnmond region, HHC in the OT was below 50%; this needs to be addressed, particularly in teaching hospitals and among physicians., (Copyright © 2022 The Author(s).

Background: Isolation precautions are recommended when caring for patients identified with highly resistant micro-organisms (HRMOs). However, the direct costs of patients in isolation are largely unknown., Aim: To obtain detailed information on the daily direct costs associated with isolating patients identified with HRMOs., Methods: This study was performed from November until December 2017 on a 12-bed surgical ward. This ward contained solely isolation rooms with anterooms. The daily direct costs of isolation were based on three cost items: (1) additional personal protective equipment (PPE), measured by counting the consumption of empty packaging materials; (2) cleaning and disinfection of the isolation room, based on the costs of an outsourced cleaning company; and (3) additional workload for healthcare workers, based on literature and multiplied by the average gross hourly salary of nurses. A distinction was made between the costs for strict isolation, contact-plus isolation, and contact isolation., Findings: During the study period, 26 patients were nursed in isolation because of HRMO carriage. Time for donning and doffing of PPE was 31 min per day. The average daily direct costs of isolation were the least expensive for contact isolation (gown, gloves), €28/$31, and the most expensive for strict isolation (surgical mask, gloves, gown, cap), €41/$47., Conclusion: Using a novel, easy method to estimate consumption of PPE, we conclude that the daily direct costs of isolating a patient differ per type of isolation. Insight into the direct costs of isolation is of utmost importance when developing or updating infection prevention policies., (Copyright © 2020 The Authors. Published by Elsevier Ltd..
