In this cluster RCT, all medical-surgical wards and ICUs of the Center where the study will be conducted, will be selected. Subsequently, cluster randomization will divide those hospital units in two arms: (1) Intervention group - 1 ICLN per ward/ICU will be identified and formed; (2) Control group - wards and ICU that will continue standard IPC practice.
Assessment, data collection, and intervention will be administered within the hospital facility. Since this hospital comprises in total 6 medical-surgical wards and 2 ICUs, each study group (i.e., Intervention group and Control group) will comprise 4 hospital units.
Data will be collected in presence at baseline (T0 - before ICLNs' implementation) and after 12 months (T1).
- Primary endpoint will be nurses' compliance with standard precautions, using a validated instrument ("Compliance with Standard Precaution Scale-Italian version; CSPS-It)
- Secondary outcomes (i.e., healthcare professionals' hand hygiene compliance, healthcare professionals' alchol-based hand rub consumption and healthcare-associated infections incidence rate) will be evaluated for all healthcare professionals working in the promoting center.
Signing of Informed Consent will only be required by nursing staff who fill-out the CSPS-It, whereas all other data collected (hand hygiene compliance, alchol-based hand rub consumption consumption and HAIs incidence) are part of usual intra-hospital surveillance practices and do not involve the collection of any personal data.
For this reason, nurses working in the selected units will be asked to participate in the study, and they will be asked to sign an Informed Consent form and will be consecutively enrolled until the sample size is reached (i.e., 100 nurses).
After cluster randomization is performed, recruitment of potential participants will begin. 4 ICLNs will be selected and every clinical nurse working full-time in the selected hospital units will be asked to participate in the present RCT. After signing the Informed Consent, baseline data collection will begin.
At baseline (T0) socio-demographic data and job-related informations (e.g., time in years of clinical experience as a nurse, study degree) will be collected. Afterward, participants will be asked to fill out a validated instrument aiming to measure compliance with standard precautions (i.e., CSPS-it). Sample size is composed only by nurses because CSPS-It is validated only for registered nurses and nursing students.
Concurrently, data regarding healthcare professionals' (i.e., doctors, nurses, support personnel, technicians) compliance with hand hygiene (HH), Alcohol-Based Hand Rub (ABHR) consumption, and Healthcare-Associated Infections (HAIs)' incidence rate will be collected.
During the 12-month ICLNs implementation program, ICLNs will be continuously supported in their activities by hospital management and by their colleagues, and they will be asked to participate in monthly educational meetings covering core elements on HAIs prevention and control, standard and isolation precaution measures, and hand hygiene paired with flexible times useful for ICLNs to create debates, reflect on barriers, and analyze situations together.
After 12 months (T1), the same data collection at baseline (T0) will be performed (i.e., CSPS-it, HH compliance, ABHR consumption, HAIs' incidence rate).
Data collection will be carried out by research assistants trained to the present protocol, HH compliance direct observations will be performed by hospital personnel not involved in this RCT, data related to AHRB consumption and HAIs rate will be collected by trained personnel working in the hospital facility.
To ensure privacy, data at baseline and follow-up will be collected, analyzed and presented exclusively in aggregate form (i.e., for the intervention group and control group).
