Role of Structured Infection Prevention and Control Training Program in Reducing Surface Contamination and hospital acquired infections: A Single Centre Study

Abstract

Introduction:  Infection Prevention and Control (IPC) is essential component for patient safety, as Hospital-acquired infections (HAIs)remain a major global challenge recognized by World Health Organization (WHO). High-risk areas such as intensive care units and operation theatres are particularly vulnerable due to invasive procedures, critically ill patients, and environmental contamination of frequently touched surface and medical equipment. The objective of this study is to assess the impact of a structured IPC training program on reducing surface contamination and the frequency of HAIs. The findings aim to support effective infection control strategies and improved outcomes in healthcare settings.>

Methodology: Retrospective interpreted time series (ITS) analysis of monthly environmental cultures

from six critical areas of Tertiary care teaching hospital (June 2022 to Dec 2023) was conducted. Surface culture reports and HAI records were analyzed before and after IPC training implementation. Descriptive statistics and chi-square tests assessed the changes in surface contamination and HAI rates.
Results: Among 619 environmental samples from six critical areas, 32 (5.1%) showed microbial growth. Positive cultures rates declined significantly across study period from 11.9% to 3.1% and 1.7% following IPC program implementation

Conclusion: There is a significant impact of implementation of infection prevention and control

policies followed by regular and structured training sessions of healthcare professionals on

surface bacterial contamination of critical areas and hospital associated infections in a tertiary

care hospital.
