Do the prevention procedures work in reducing infections?

Abstract Introduction Healthcare-associated infections (HCAIs) pose significant challenges in healthcare settings. Poor environmental hygiene contributes to HCAI. This study aims to evaluate and to assess the effectiveness of HCAI containment practices in nursing homes (NH). Methods The study examined infection prevention procedures in eight NHs supervised by the Multidisciplinary Commission of the Tuscany South-East Local Health Authority of Italy. Infection frequencies were obtained from NHs management and compliance with preventive procedures was assessed by inspection reports. Infection prevention protocols, including cleaning and disinfection procedures, were referenced from ministerial guidelines for hospital and territorial facilities. Comparisons was done whit Mann-Whitney test, using STATA. Results In 2023 more frequent infections were SARS-CoV-2 (19.5%), urinary tract infections (17%), pharyngitis (15.7%), influenza-like syndromes (ILI) (15%), and pneumonia (9%). Compared to 2022, significant improvements were observed in legionellosis surveillance, laundry, sanitary procedures, instrument disinfection, and hairdressing services. Non-compliance to specific procedures revealed differences in infectious onset like cleaning process verification with fungal infections (P = 0.01; M = 2,5), gastrointestinal infections (P = 0.04; M = 1.5); cleaning sanitary pans with Clostridium Difficile gastrointestinal infections (P = 0.04; M = 2); instrument disinfection with gastrointestinal infections (P = 0.04; M = 1.5) conjunctivitis (P = 0.01; M = 8); laundry procedures with pneumonia (P = 0.04; M = 18) and ILI (P = 0.04; M = 35). Conclusions These findings emphasize the importance of well-defined procedures in reducing HCAIs. While preventive measures demonstrate efficacy, continuous efforts are necessary for their consistent implementation. Continuous monitoring and stakeholder engagement are essential for developing sustainable strategies in preventing healthcare-associated infections. Key messages • Healthcare-associated infections are a significant complication in the healthcare sector and require effective practices in nursing homes. • Prevention measures are effective, but continuous and collaborative effort is needed to ensure their uniform implementation and develop more effective strategies in preventing HCAI.
