Background and study aims
Healthcare-associated infections (HAI) are a major public health problem, with an estimated hundreds of millions of new episodes occurring annually worldwide. They affect about 7% and 10% of all hospitalised patients in developed and developing countries, respectively, and are responsible for millions of deaths worldwide each year. Around 50-70% of HAIs are due to healthcare workers (HCWs)’ lack of proper hand hygiene (HH). Proper HH is one of the most efficient methods to prevent HAI. For this reason, the World Health Organization (WHO) recommends a Multimodal Strategy with five elements to improve HH practices in the healthcare setting. In that list, recommendation number three (performing observation of HH practices and providing timely performance feedback) is one of the most challenging because evaluating HH practices by direct observation is a time-consuming and costly task. An electronic device intended to continuously monitor HH practices and to provide real-time feedback to healthcare workers could be very useful. The aim of this study is to identify the effectiveness of using a new device providing automatic, immediate and personal feedback regarding the quality of hand hygiene gesture in enhancing the quality of their HH action.
Who can participate?
Health care workers aged 20 to 65 working in patient-care activities
What does the study involve?
Health care workers (grouped in units) are randomly assigned as to when they receive the intervention. Participants are given a device that is worn on their wrist and a pocket-sized alcohol-based hand rub (ABHR) with a clip that provides personal, automatic and individualized feedback on their hand hygiene quality. This is the second phase of a study performed in 2017 registered with the number ISRCTN25430066.
What are the possible benefits and risks of participating?
Participants may benefit from having personalized and individual feedback regarding their hand hygiene practices and may benefit from the improvement of the quality of each hand hygiene action. There are no notable risks with participating.

| Scientific title | Impact of using a device providing individual feedback on healthcare workers hand hygiene behaviour: a stepped-wedge cluster-randomized clinical trial - phase II |
| Study acronym | SmartRub |
| Study objectives | The researchers hypothesize a 20% absolute increase in the number of healthcare workers (HCWs) performing at least 60% of correct hand hygiene actions if they receive continuous feedback about their hand hygiene action performance. A correct hand hygiene action is defined as the use of at least 80% of the customized volume of alcohol-based hand rub and the performance of hand friction for at least 12 seconds. This is the second phase of a study performed in 2017 registered with the number ISRCTN25430066. |

| Health condition(s) or problem(s) studied | Hand hygiene |
| Intervention | The intervention is an electronic device in the form of a wrist band and a cylinder added into a pocket-size individual bottle of alcohol-based hand rub (ABHR) that measures the duration of hand friction and volume of ABHR used in each hand hygiene gesture and provides a personal, automatic and individualised feedback on those parameters. A stepped wedge trial was designed where clusters (wards) will be randomly and sequentially rolled out from a fixed pre-baseline (no device: 1 month), to the baseline (device without feedback: from 1 to 4 months) followed by the adaptation (1 month) and intervention period (device with feedback: from 1 to 4 months) and finally a post-intervention period (immediate: 1 month and delayed: 1 month). The length of the timepoints is 1 month and the study will have four steps. At the beginning of the study, none of the wards will be exposed to the intervention (pre-rollout period divided in pre-baseline (no device) and baseline (device without feedback)) and at the end of the study, all wards will be exposed to the intervention (post-rollout period). Additionally, a fixed post-intervention period (no feedback) immediate and delayed (3 months later) was also designated in order to assess the sustainability over time of the intervention (secondary outcome). The time of exposure to the active device will be split into four steps with a longer period of 4 months in step 1, to a shorter period of exposure of 1 month in step 4. Thus, the duration of the trial will be 11 months. The primary outcome will be assessed at the HCW level; continuous measures will be taken by the device, regarding the volume of ABHR and duration of hand friction, from the same HCWs throughout the study in order to assess the change in HH quality and its relation to the intervention (active device). It will be thus a closed cohort design. The study periods correspond to: - Pre-baseline period (no device): this period will last 1 month. HCWs will perform their normal daily activities and will not have the device. HCWs will be directly observed regarding their HH compliance (secondary outcome) once. - Baseline period (device without feedback): this period will last from 1 to 4 months, depending on the step to which the ward is allocated. HCWs will perform their normal daily activities and will use the device. However, the device will not provide any feedback to the HCW using it. Data will be obtained regarding the volume of ABHR used and duration of hand friction continuously by the device (baseline for the primary outcome). - Adaptation period: this period will have a fixed duration of 1 month in all steps and it will be immediately before the intervention period and after the baseline period. HCWs will perform their normal daily activities and will continue to use the device. The feedback will be turned on and adjusted progressively to reach the target volume of HCW using it. This will be done by the engineers in the team working in close proximity to the HCWs. Data regarding the volume of ABHR used and duration of hand friction will be not included in the primary outcome in the statistical analysis. - Intervention period: this period will last from 1 to 4 months, depending on the step to which the ward is allocated. HCWs will continue to use the device introduced during the baseline and adjusted during the adaptation period. There will be no adjustments in this phase. The device will provide immediate feedback after each hand hygiene action performed by the HCW on the volume of ABHR and duration of hand friction. - Immediate post-intervention period: this period will have a fixed duration of 1 month in all steps and will take place immediately after the end of the intervention period. After the end of the intervention period, HCWs will still wear the device, but the feedback will be deactivated. This period will help to evaluate the post-immediate sustainability of hand hygiene quality improvement (secondary outcome). - Delayed post-intervention period: this period will have a fixed duration of 1 month in all steps. After the end of the immediate post-intervention period, HCWs will stop wearing the device of the study. Three months after they will be asked to wear the device again without feedback activated. This period will help evaluate the long term sustainability of hand hygiene quality improvement (secondary outcome). In parallel, HCWs will be directly observed regarding their HH compliance (secondary outcome) once per timepoint (monthly) from the pre-baseline to the delayed post-intervention period (11 months). |

| Primary outcome measure | The proportion of HCWs performing correct hand hygiene actions, as defined in the hypothesis, using the device without feedback (baseline for device period) or device with feedback (intervention period). This data will be collected automatically and continuously by the device at baseline and intervention periods (5 months). |
| Secondary outcome measures | 1. Hand hygiene compliance is measured by direct observation by well-trained IPC professionals according to the WHO methodology at the individual HCW level, once per month during the entire study period (11 months) 2. Hand hygiene quality (volume of ABHR, duration of hand friction) and frequency of hand hygiene is measured using the device collecting automatic and continuous data at baseline and intervention (5 months) 3. Adherence to hand hygiene device is measured using how many hours the device is used by HCWs using the device collecting automatic and continuous data at baseline and intervention (5 months) 4. Hand hygiene quality (volume of ABHR, duration of hand friction) and frequency of hand hygiene at post-intervention is measured continuously by the device to assess for the sustainability of the intervention the month after and at 3 months after the end of the intervention (2 months) 5. Satisfaction and perception of the usefulness of the device by HCWs is measured using a questionnaire distributed to participants to evaluate their experience with the device at the end of the intervention 6. Adverse events related to the device are measured using a list of open responses (ie., skin irritation, injury to patient, etc) whenever participants have a complaint |
