Purpose: Hospital-acquired infections in the Intensive Care Unit (ICU) account for an increase in morbidity and mortality leading to serious health complications. This study aims to determine the effect of a multimodality approach including disinfection and physical separation on the infections prevailing in ICU.
Methods: The study employed prospective cross-over analysis to assess the 738 individuals (560 males and 178 females) at the ICU, Aseer Central Hospital, Saudi Arabia. The intervention programs were carried out for 3 years (2013-2015). It included the application of hydrogen peroxide and silver cations, physical separation, and compartmentalization of ICU. Acinetobacter spp., E. coli, and staphylococci were isolated, identified, and used to evaluate the efficacy of the intervention program.
Results: The results provide endotracheal tube as the main specimen type (34.7%) followed by blood (29.1%), tracheal secretion (7.7%), wound (6%), urine (5.7%), throat swab (5.4%), sputum (3.7%), and other specimens (7.7%). It also showed the infection rate decreased from 14.3% to 4% in the last three months after continuous interventions (R2 = 0.44). There was a decrease in the occurrence of bacteria after an intervention (p = 0.036).
Conclusion: The outcome of the study revealed that mist and separation measures offered a significant decrease in infections at the ICU as per the measurement of the most hazardous nosocomial pathogens.
