The World Health Organization hand hygiene observation method

Monitoring hand hygiene adherence and providing performance feedback to health care workers is a critical component of multimodal hand hygiene promotion programs, but important variations exist in the way adherence is measured. Within the framework of the World Health Organization's (WHO) First Global Patient Safety Challenge known as "Clean Care is Safer Care," an evidence-based, user-centered concept, "My five moments for hand hygiene," has been developed for measuring, teaching, and reporting hand hygiene adherence. This concept is an integral part of the WHO's hand hygiene improvement strategy conceived to translate the WHO Guidelines on Hand Hygiene in Health Care into practice. It has been tested in numerous health care facilities worldwide to ensure its applicability and adaptability to all settings irrespective of the resources available. Here we describe the WHO hand hygiene observation method in detail-the concept, the profile and the task of the observers, their training and validation, the data collection form, the scope, the selection of the observed staff, and the observation sessions-with the objective of making it accessible for universal use. Sample size estimates, survey analysis and report, and major bias and confounding factors associated with observation are discussed

Double-blind, randomized, crossover trial of 3 hand rub formulations: fast-track evaluation of tolerability and acceptability

OBJECTIVE: To compare healthcare workers' skin tolerance for and acceptance of 3 alcohol-based hand rub formulations. DESIGN: Double-blind, randomized, crossover clinical trial. SETTING: Intensive care unit in a university hospital. PARTICIPANTS: Thirty-eight healthcare workers (HCWs). INTERVENTION: A total of 3 alcohol-based hand rub formulations (hereafter, formulations A, B, and C) were used in random order for 3-5 consecutive working days during regular nursing shifts. Formulations A and B contained the same emollient, and formulations B and C contained the same alcohol at the same concentration. Use of each test formulation was separated by a "washout" period of at least 2 days. A visual assessment of skin integrity by a blinded observer using a standard 6-item scale was conducted before and after the use of each formulation. Univariate and multivariate analyses were used for the assessment of risk factors for skin alteration, and product acceptability was assessed by use of a customized questionnaire after the use of each formulation. RESULTS: Thirty-eight HCWs used each of 3 formulations for a median of 3 days (range, 3-5 days). The mean amount of product used daily (+/-SD) was 54.9+/-23.5 mL (median, 50.9 mL). Both subjective and objective evaluation of skin conditions after use showed lower HCW tolerance for product C. Male sex (odds ratio [OR], 3.17 [95% confidence interval {CI}, 1.1-8.8]), fair or very fair skin (OR, 3.01 [95% CI, 1.1-7.9]), skin alteration before hand rub use (OR, 3.73 [95% CI, 1.7-8.1]), and use of formulation C (OR, 8.79 [95% CI, 2.7-28.4]) were independently associated with skin alteration. CONCLUSIONS: This protocol permits a fast-track comparison of HCWs' skin tolerance for different alcohol-based hand rub formulations that are used in healthcare settings. The emollient in formulation C may account for its inferior performance

Knowledge of standard and isolation precautions in a large teaching hospital

OBJECTIVE: To assess the level of knowledge regarding and attitudes toward standard and isolation precautions among healthcare workers in a hospital. METHOD: A confidential, self-administered questionnaire survey was conducted in a random sample of 1500 nurses and 500 physicians in a large teaching hospital. RESULTS: A total of 1,241 questionnaires were returned (response rate, 62%). The median age of respondents was 39 years; 71.9% were women and 21.2% had senior staff status. One-fourth had previously participated in specific training regarding transmission precautions for pathogens conducted by the infection control team. More than half (55.9%) gave correct answers to 10 or more of the 13 knowledge-type questions. The following reasons for noncompliance with guidelines were judged as "very important": lack of knowledge (47%); lack of time (42%); forgetfulness (39%); and lack of means (28%). For physicians and healthcare workers in a senior position, lack of time and lack of means were significantly less important (P <.0005). On multivariate linear regression, knowledge was independently associated with exposure to training sessions (coefficient, 0.33; 95% confidence interval, 0.08 to 0.57; P =.009) and less professional experience (coefficient per increasing professional experience, -0.024; 95% confidence interval, -0.035 to -0.012; P <.0005). CONCLUSIONS: Despite a training effort targeting opinion leaders, knowledge of transmission precautions for pathogens remained insufficient. Nevertheless, specific training proved to be the major determinant of "good knowledge"

Lower risk of peripheral venous catheter-related bloodstream infection by hand insertion

Introduction Little is known about the bloodstream infection (BSI) risk associated with short-term peripheral venous catheters (PVCs) and no large study investigated the insertion site-related risk for PVC-BSI. Methods We performed a cohort study at the University of Geneva Hospitals using the prospective hospital-wide BSI surveillance database. We analyzed the association between insertion site and risk of PVC-BSI on the upper extremity using univariable and multivariable marginal Cox models. Results Between 2016 and 2020, utilization of 403′206 peripheral venous catheters were prospectively recorded in a 2000-bed hospital consortium with ten sites. Twenty-seven percent of PVC (n = 109′686) were inserted in the hand. After adjustment for confounding factors, hand insertion was associated with a decreased PVC-BSI risk (adjusted hazard ratio [HR] 0.42, 95% CI 0.18–0.98, p = 0.046) compared to more proximal insertion sites. In a sensitivity analysis for PVCs with ≥ 3 days of dwell time, we confirmed a decreased PVC-BSI risk after hand insertion (HR 0.37, 95% CI 0.15–0.93, p = 0.035). Conclusion Hand insertion should be considered for reducing PVC infections, especially for catheters with an expected dwell time of more than 2 days

Educating healthcare workers to optimal hand hygiene practices: addressing the need

The education of healthcare workers is essential to improve practices and is an integral part of hand hygiene promotional strategies. According to the evidence reviewed here, healthcare worker education has a positive impact on improving hand hygiene and reducing healthcare-associated infection. Detailed practical guidance on steps for the organization of education programmes in healthcare facilities and teaching-learning strategies are provided using the World Health Organization (WHO) Guidelines for Hand Hygiene in Health Care as the basis for recommendations. Several key elements for a successful educational programme are also identified. A particular emphasis is placed on concepts included in the tools developed by WHO for education, monitoring and performance feedback
