Background And ObjectiveHand hygiene (HH) is the simplest and most effective measure for the prevention of infection related to healthcare. Despite this, compliance in healthcare professionals continues to be suboptimal. The aim of this study is to assess the impact of an expanded World Health Organization (WHO) multimodal strategy on HH compliance in healthcare personnel.Material And MethodsA quasi-experimental before-after study was designed, carrying out the expanded WHO multimodal strategy in 2018, aimed at professionals in a tertiary hospital. In this strategy, apart from applying the 5 pillars of the WHO, a video was made, the administration of the WHO perceptions questionnaire and an incentive to the service/unit with better compliance, adding to the training a modality of practical workshops. The compliance percentages for 2017 and 2018 were compared.ResultsIn 2017, 1056 opportunities were observed, registering 631 HH actions, with global compliance of 60% (95% CI 56.7-62.7). In 2018, with 1481 opportunities observed and 1111 HH actions, compliance was 75% (95% CI 72.7-77.2) (P<.001). This compliance increased in all professional categories and in all indications.ConclusionsThe application of an expanded multimodal strategy has a positive impact on HH compliance. Strategies should be directed to the categories with the worst compliance and continuously over time.Copyright © 2022 Elsevier España, S.L.U. All rights reserved.
