Pathogenic and Non-Pathogenic Microbial Presence in Ventilator Associated Pneumonia Patients in Intensive Care Unit and Safety Protocols Under Surveillance of Healthcare Provider: A Research Study

Abstract

Ventilator-associated pneumonia (VAP) is a common hospital-acquired infection that is associated with longer stays in intensive care units (ICUs) and under mechanical ventilation for more than 48 hours. This article explores the prevalence and impact of VAP on mortality and morbidity, emphasizing the microbial associations involved in hospital-acquired infections. Various infections, including Lung infections, surgical site infections, sepsis, and urinary tract infections, are discussed, along with their associated microorganisms. Diagnostic criteria for VAP and related infections are outlined, highlighting the importance of microbiological testing for accurate diagnosis. The underlying factors for VAP acquisition in ICU patients are identified, and prompt antibiotic initiation is emphasized as a critical first-line defense against VAP. In this study, we have populated data from 100 ICU patients, among which 45 were suffering from VAP. It was found that female patients (57.40%) were more affected than male patients (30.43%). The decreasing PaO2 level was seen to be the early sign of infection. It was found that the time of ventilation was the major factor influencing the VAP. The most common organism causing infection in our study was found to be Staphylococcus Aureus (45.1%). The prognosis of early-onset VAP was 35.55% while compared to Late-onset VAP 64.44%. When compared to VAP and Non-VAP patients there was not very huge difference with 55% and 45% respectively. The other factor was age and position. Implementation of Prevention strategies, such as protective environments and HEPA filtration systems, is proposed to reduce VAP incidence. Proper diagnosis, treatment, and prevention are crucial to combatting VAP and enhancing patient outcomes in hospital settings.
