SUMBER INFEKSI HAI/HCAI
MODES OF TRANSMISSION
• Parenteral Transmission – the spread of an agent through intact skin by a sharp e.g., needle stick injury.
• Common Vehicle Transmission – the spread of an agent through a common contaminated source e.g., multi-dose vials.
• Vector Transmission – occurs when a host is bitten by an animal or insect carrying the infectious agent e.g., mosquito transmitting and West Nile virus.

Factor ExampleAge Neonates, elderly patientsUnderlying disease System of organ failure (e.g. liver cirrhosis, diabetes, mellitus, chronic obstructive pulmonary disease, renal failure), cancer, neutropeniaImmunodeficiency Congenital, or acquired, (e.g. AIDS, immunosuppressive therapy, malnutrition)Specific immunity Susceptibility to viral infectionsBreach of Mucocutaneous Trauma, burns, surgery, endoscopy, indwelling devices barriers
Mucosal and skin diseasesAnesthesia, sedation Suppression of cough and peristalsis, hypoventilationAntibiotics, antacids Alterations of resident microflora and decrease of resistance to colonization by hospital flora
Selection of antibiotic-resistant mutants and naturally resistant bacteria and yeasts

AIMS OF HOSPITAL INFECTION SURVEILLANCE
To identify high-risk patients and procedures and assign infection control priorities To monitor trends over time of incidence and patterns
of infection To detect outbreaks of hospital infection To evaluate the efficacy of prevention and control
interventions To evaluate quality assurance programs To educate and motivate health care providers and
decision makers
A number of aims can be assigned to hospital epidemiologic surveillance systems
Struelens MJ : Hosp. Infec. Control, in Amstrong & Cohen : Infect. Dis, 1999
The Awareness of HAI/HCAI Infection Control
• Over the past 30 years, nosocomial infection surveillance, prevention and control programs have been integrated into hospitals
• The goal is to ensure the well being of patients, staff, visitor and others in the healthcare environment
D W
The Critical Importance of HAI/HCAI Infections 1
• In 1976 the Joint Commission on Accreditation of Health Care Organizations (JCAHO) highlighted the nosocomial infection as preventable & controllable adverse hospital outcomes
Scheckler WE et al Am J Infect Contr 1998;26:47 D W
The Critical Importance of HAI/HCAI Infections 2
JCAHO published standards for :– Organization Surveillance– Reporting Evaluation– Record maintenance – & other requirements
For infection prevention & control activities as a condition for hospital accreditation
Scheckler WE et al Am J Infect Contr 1998;26:47
D W
The Benefit of HAI/HCAI Infection Control Programme
• Subsequent analyses have demonstrated that nosocomial infection prevention and control programs are:
– Clinically effective – Cost effective
SENIC (Wenzel 1995)
D W
Goals for Infection Control
3 principal goals for hospital infection control programs :
• Protect the patient;• Protect the healthcare worker; visitors, and others in the healthcare environment;• Accomplish the previous two goals in
a cost-effective manner
Scheckler WE et al Am J Infect Contr 1998;26:47 D W
Monitoring the Achievement of Infection Control Goals 1
• Every healthcare institution must developed specific objectives & outcome measures to determine whether they have achieved their infection control goals
JCAHO
D W
Monitoring the Achievement of Infection Control Goals 2
• The outcome measures should relate directly to the specific goals of the infection control program, namely:
– To measure the effectiveness of procedures, policies, or programs to protect patients & healthcare providers
– To determine the cost effectiveness of these activities
D W
The Essential of Hospital Infection Control Program
Hospital infection control is a quality improvement activity that focuses on improving the care of patients and protecting the health of staff
D W
Paradigm in Infection Control= Quality improvement
programs
• Ongoing data collection & analyses• Problem identification and definition• Intervention to improve outcomes• Reassessment to ensure that the
intervention has led to the desired result
D W
HAI/HCAI INFECTION CONTROL PROGRAM
Target for HCWThe save delivery of health care
Promote HCW awareness - Of NI as a problem- That NI can (in part) be prevented
HospitalsShould do the sick no harm

A RATIONAL CLASSIFICATION OF HOSPITAL INFECTION PREVENTION STRATEGIES(2)
Target Objective Example of strategy
Antimicrobial To prevent the Restricted usage of broad-spectrum resistance emergence, and antimicrobial agents
spread of Optimized anti-infectious therapy (agents,
resistance genes dosage and duration)
To prevent the Detection, monitoring and timely reporting
spread of of antimicrobial resistanceresistant strains Isolation precautions and
treatment of of micro- carriers of transmissible resistant
strains organisms Molecular epidemiologic studies to distinguish between mutant selection, gene or clone dissemination
