Hospital infection control- Lec. No. 1- Introduction

Hospital Infection Control
Lecture no. 1
Introduction

Infection Control 
Objectives:
Describe the role of isolation in preventing the spread of certain infections
Describe each type of isolation with examples of diseases
Understand significance of correct sequence of donning and removing PPE.

ISOLATION – foundation for preventing transmission of infectious agents associated w/healthcare delivery
Role – creates a protective environment that is required to contain the transmission of infectious agents

Infection Control 
Objectives:
Understand the significance of antibiotic resistant organisms seen in hospitals
Understand how surveillance for hospital acquired (nosocomial) infections is performed and the significance of surveillance data

Antibiotic Resistant – Global Health Problem
Increasing morbidity
contributes to increasing mortality
increase health care costs – nosocomial pathogens est to exceed 1.3 Billion annually
Chain of Infection
Break the chain
pathogen – appropriate antibiotics
Reservoir – patients – frown when we get rid of them
portal of exit – Mask
mode of transmission – isolation
portal of entry – N-95 resp
susceptible host - immunizations

What is Infection Control?
Identifying and reducing the risk of infections developing or spreading
Nosocomial Infections
Develops when a patient is staying at a healthcare facility AND was not present when the patient was admitted to the facility
At least 5% of patients hospitalized each year in the United States develop nosocomial infections. Many are preventable
