Definition 1

Definition(1)

Old concept:

  • Nosocomial Infection = Hospital acquired infection

    - An infection that occured during hospitalization (> 3 X 24 hours after admission) which are not present nor incubating upon hospital admission

    - Infection at the same location but the causative microorganism was different than at addmission OR the same microorganism but different location


Definition 2

Definition(2)

  • Problems of old definition:

    1.Focus on infection occuring in the hospital

    only.

    What about in other health care system but

    not hospital?While many home-care are

    availlable now?

    2. Focus on patient’s infection

    What about healthcare worker?


Definition 3

Definition(3)

New terminology:

nosocomial Infection =

Health-careassociated Infection

Health-care related Infection


Healthcare associated infection

Healthcare-associated infection

Definition:

An infection occurring in a patient during the process of care in a hospital or other healthcare facilitywhich was not present or incubating at the time of admission.

This includes infections acquired in the hospital but appearing after discharge,

and also occupational infections among staff of the facility


In indonesia

In Indonesia

  • The term nosocomialinfection still being used

  • For nosocomialinfection occured in the hospital: Hospital Infection (”InfeksiRumahSakit”)

  • Control Program of HAIs called: “PencegahandanPengendalianInfeksiRumahSakit” (“PPIRS”)


Types of infe ct i ons 1

Types of Infections(1)

Four categories:

Surgical site infections(SSI)

Central line-associated bloodstream infections(CLABSI)

-Hepatitis B and C

- HIV / AIDS

- SARS

Why does hais important

Why does HAIs important?


Why does hais important1

Why does HAIs important?

1.Increase morbidity & mortality

2.Prolong length of stay (LOS)

3.Increase cost

4.Related to ‘image’/ quality of the hospital

5.Important in medicolegaland “patient

safety” aspects.


Impact of hais

Impact of HAIs

They lead to

functional disability and emotional stress to the patient

disabling conditions that reduce the quality of life

They are one of the leading causes of death


Impact of hais cont d

Impact of HAIs (cont’d)

  • The increased economic costs are high:

    - Increased length of hospital stay

    - extra investigations

    - extra use of drugs

    - extra health care by doctors and nurses


Nosocomial infections cost

Nosocomial Infections Cost

  • The cost varies according to the type and severity of these infections

  • An estimated: 1 - 4 extra days for a UTI

    7 – 8 days for a surgical site infections

    7 – 21 days for a blood stream infection

    7 – 30 days for pneumonia

  • The CDC has recently reported that US$5 billion are added to US health costs every year as a result of NI


Impact of nosocomial infections cont d

Impact of Nosocomial Infections (cont’d)

  • Organisms causing N.I. can be transmitted to the community through discharged patients, staff and visitors

  • If organisms are multi-resistant they may cause significant disease in the community


Goals of infection control

Goals of infection control

  • To protect the patients from HAIs e.g UTI, SSI, IV line infection, pneumonia (HAP, VAP), Blood stream infection (sepsis)

  • To protect the patients from others infection which acquire through contact with other patients or healthcare worker whom colonized by contagious microorganisms.

  • To protect healthcare workers, Visitor, in hospital environtment from infections

SIX COMPONENTS OF THE CHAIN OF INFECTION

Schaffer SD et al: Infection Prevention and Safe Practice, Mosby, 1996


Risk fa c tor s 1

Risk Factors(1)

Age: neonatus >>

Interuption of anatomical barrier:

- Urine catether

- Operationprocedure

- Respiration intubation

- Vein/artery canule

- Burn wound and trauma


Risk f a c tor s 2

Risk factors(2)

Implantation of:

- “indwelling catheter”

- “surgical suture material”

- “cerebrospinal fluid shunts”

- “valvular / vascular prostheses”

Changes in normal microflora :

antibiotics usage


Routes of transmission of infection

Routes of Transmission of Infection

A susceptible host and appropriate inoculum of infecting microorganism with an appropriate route of transmission contributed in majority of case

  • Airborne (resp tract, aerosols from equipment etc)

  • Contact spread (person to person)

  • Food borne spread

  • Blood borne spread

  • Self infections (endogenous) and cross infections


Transmission 1

Transmission(1)

  • Contact transmission:

    - Direct:

    body contact

    physically causative microorganism transfer

     physical examination, patients bathing

    - Indirect: most of the time !!!

    contact through objects (tools)

    instrumentation, needle, bandage

     unwashed hand


Transmission 2

Transmission(2)

  • Droplet transmission :

    - droplet particles > 5 μm

    - coughing, sneezing, talking

    - short transmission distance, and only short time in the air

    - “deposit” at conjungtival mucous, nose, mouth

    - e.g.: Diphteria, Pertussis, Hib, Mycoplasma

    Influenza Virus , mumps, rubella


Transmission 3

Transmission(3)

  • Airborne transmission :

    - small particles < 5 μm

    - long standing in the air

    - long transmission distance

    - easy inhaled

    - e.g : Mycobacterium tuberculosis

    varicella virus, morbilli,

    fungi spore.


Pathophysiology

Pathophysiology

Within hours of admission, colonies of hospital strains of bacteria develop in the patient's skin, respiratory tract, and genitourinary tract.

Risks factors for the invasion of colonizing pathogens can be categorized into 3 areas: iatrogenic, organizational, and patient-related


Iatrogenic risk

Iatrogenic risk

  • Iatrogenic risk factors: include pathogens on the hands of medical personnel, invasive procedures (intubation and extended ventilation, indwelling vascular lines, urine catheterization), and antibiotic use and prophylaxis.


Organizational

Organizational

  • Organizational risk factors include:contaminated air-conditioning systems, contaminated water systems, and staffing and physical layout of the facility (eg, nurse-to-patient ratio, open beds close together).


Patient associated

Patient associated

  • Patient risk factors include the severity of illness, underlying immunocompromised state, and length of stay.

  • Prolonged stay in the hospital is a Major contributing factor


Blood stream infections

Blood stream infections

  • Most important pathogen:

    coagulase negative Staphylococcus (CONS): 39.3%

  • 10 – 15% of patients with HAI have a BSI

  • Needle sticks may offer a path of entry for the microbes


Pneumonia

Pneumonia

  • Most important pathogens

    • Staphylococcus aureus: 16.8%

    • Pseudomonas aeruginosa: 16.1%

  • 10 – 15% of patients with a HAI get pneumonia

  • 20 – 50% mortality rate

    • Intubation and mechanical ventilation increase the risk of pneumonia by S. aureus

    • Pneumonia usually caused by aspiration of bacteria clusters found in resp. Tract/GI tract


Urinary tract infection

Urinary tract infection

  • Most important pathogens

    • Escherichia coli – 18.2%

    • Candida albicans – 15.3%

  • Up to 40% of patients with HAIs get a UTI

  • E. coli is a natural inhabitant of the GI tract

    it is commonly found near the anterior urethra

  • Candida albicans is a natural inhabitant of the GI and genital tract

  • Normal urination clears the urethra of harmful microbes while catheterization may allow microbes to colonize and infect the urinary tract


Surgical site infection

Surgical site infection

  • Most important pathogens

    • Enterococci spp. – 14.5%

    • Coagulase negative Staphylococcus (CoNS)– 13.5%

  • Up to 54% of patients with HAI who have also had surgery get a SSI: 500,000 infections/year

  • Enterococci spp. are a natural inhabitant of the GI tract

  • Urinary catheterizations and antimicrobial use during hospital stays increases risk of infection


3 major players in hais

3 Major players in HAIs

1. Antimicrobial use in hospitals and long-term care facilities: has produced resistant strains that are often found colonizing health care workers. These strains can be transferred to patients by normal human contact

  • Medical devices such as catheters and sutures offer a portal of entry for the microbes

    2. Failure of hospital personnel to follow basic infection control: Handwashing, PPE etc.

    3. Hospital patients are increasingly immunocompromised


Prevention and control

Prevention and Control

  • The basic responsibility of any good hospital remain with establishment of good infection control policies, which can always be achieved with

  • 1. An infection control committee

  • 2. An Infection team

  • The Functions of the Committee:

  • To do surveillance and infection monitoring of hygiene practices.

  • Educate the Medical and Paramedical staff on policies relating to prevention of infection, and safe procedures


Infection control nurse

Infection Control Nurse

  • Is the key member of the team

  • Maintain the close working relations between Microbiology Laboratory, different clinical services and supportive services like laundry, pharmacy and engineering

  • Collect information and document on HAIs


Universal precautions
