•

contaminated sharp objects that cut or puncture the skin

•

contaminated splash with eyes, mouth, or nose

•

sharing needles

sexual contact

Hepatitis B Virus

• 100 times more infectious vs. HIV • Can live on dried surfaces for one week • 6-30% chance of infection from an exposure (puncture wound) • 85-90% of those infected will recover in 6-8 weeks • 10-15% will become carriers and develop chronic liver disease • Vaccine preventable – 3 doses, highly effective

Hepatitis

• Risk for exposure from a

C Virus

contaminated puncture wound - 3.3% - 10% • Most transmission is transfusion or IV drug use related • About 4 million people are infected • Chronic infection develops in 80% • Not vaccine preventable

HIV

• Very fragile virus and will not survive long outside the body • Risk of transmission through a needlestick or cut with HIV infected blood is 0.3%. A splash to the eyes or nose or mouth is 0.1% • Risk to non-intact skin to HIV infected blood is estimated to be less than 0.1%

Hand washing

Why By what When How

Hand Washing

• Why: • Hand washing is your first defense in infection control.

Handwashing what to use ?

• Handwashing with soap and water in non-health care settings • When health care personnel's hands are visibly soiled, they should wash with soap and water. • When health care personnel's hands are not visibly soiled , use alcohol-based handrubs • Handrubs and hand washing should be observed before and after each patient.

Hand Washing

When: 􀁸 After contact with blood or other body fluids 􀁸 Before and after handling a patient 􀁸 Between glove changes 􀁸 Before and after eating/smoking 􀁸 After using the rest room

Types of hand washing:



Social Hand washing



Hygienic hand washing or Antiseptic hand washing



Surgical Hand washing



Alcohol hand rub

Hand Washing

How to do It Right!

4.

First wet Wet hands under running water and apply nonabrasive soap Next Vigorously rub palms,back of hands, between fingers, and wrists for 15 – 20 seconds Rinse well and dry your hands dry with paper towel (not cloth towel or other fabric) Avoid chapped and cracked hands if possible. Use a water-based hand lotion frequently. Petroleum-based products and Vaseline break down latex .

Why alcohol based hand rub?

• Alcohol-based hand rubs take less time to use than traditional hand washing. • Alcohol-based handrubs significantly reduce the number of microorganisms on skin and are fast acting • Allergic contact dermatitis due to alcohol hand rubs is very uncommon.

Questions

Personal Protective Equipment (PPE)

 Is specialized clothing or equipment worn or used by you for protection against a hazard.

 It helps to interrupt the transmission of micro organisms between patients and staff.

Gloves

 Wear gloves (clean, nonsterile ) when touching – blood, – body fluids, secretions, excretions, – contaminated items. – just before touching mucous membranes – just before touching nonintact skin  Change gloves – between tasks and procedures on the same patient – after contact with material that may contain a high concentration of microorganisms  Remove gloves promptly – after use, – before touching noncontaminated items and environmental surfaces – before going to another patient,

Gloves

 Does not eliminate the need for hand hygiene.  Hand hygiene does not eliminate the need for gloves.  Gloves reduce hand contamination by 70 percent to 80 percent  Gloves should be changed before and after each patient.

 Hands must be washed after removal because gloves may be punctured and your hands are easily contaminated as the gloves are taken off.  Gloves must be discarded after each procedure.

WEAR -Mask -Eye Protection -Face Shield

To protect eyes, nose, and mouth during procedures and patient care activities that are likely to generate splashes or sprays of blood, body fluids, secretions, and excretions. Such activities are not commonly encountered in ward settings • respiratory suction • scrubbing of instruments • endoscopy, • management of women in labor • surgical procedures, particularly orthopedic and cardiac surgery.

Wear a gown

• Wear a gown to protect skin and to prevent soiling of clothing during procedures and patient-care activities that are likely to generate splashes or sprays of blood, body fluids, secretions, or excretions.

• Select a gown that is appropriate for the activity. • Remove a soiled gown as promptly as possible, and wash hands • Avoid actions which may splash, spray or splatter or create droplets. Never pipette or suction infectious materials by mouth.

Practice Safe Clean Up In All Situations:

–

Do not

• recap used needles • remove used needles from disposable syringes by hand, • bend, break, or otherwise manipulate used needles by hand.

• pick up sharps with bare hands - use tongs/dust pan and broom –

DO

• Use gloves • Place disposable sharp items in appropriate puncture-resistant containers for disposal, • place reusable syringes and needles in a puncture-resistant container for transport to the reprocessing area.

• Always handle trash as if a sharp might be present •

Use mouthpieces, resuscitation bags, or other ventilation devices as an alternative to mouth-to-mouth resuscitation methods

–

Take care when

• using needles, scalpels, and other sharp instruments • handling sharp instruments after procedures; • cleaning used instruments; • disposing of used needles. Never,

Sharp Safe Policy:

Used sharps should be handled as little as possible to minimize the risk of injury.

Needles must not be re-sheathed. If a needle and syringe needs to be disassembled then it should first be re-sheathed using a single handed technique.

Sharps must be discarded immediately after use into a designated sharps container.

Sharps must never be carried in the hand to the point of disposal, but either carried in a tray or a sharps container brought to the point of use.

They should not be passed by hand between staff.

Needles should not be removed from syringes but discarded as a single unit.

The bins must never be more than ¾ filled, sharps protruding from the aperture of a sharps bin present a major hazard to other users.

Bins must be securely closed and labeled with the date and point of origin before being sent for disposal.

Where blood or other potentially infectious materials are present, never – Eat – Drink – Smoke – apply cosmetics – or handle contact lenses

Practice Safe Clean Up In All Situations:

•

Use biohazard label for all infectious waste

•

Use leak proof, closable, puncture resistant and labeled Containers

•

Separate Biohazard waste from regular waste

•

Keep Bagged biohazard waste in the container through out disposal

Practice Safe Clean Up In All Situations:

Patient-Care Equipment

• Handle used patient-care equipment soiled with blood, body fluids, secretions, and excretions in a manner that prevents skin and mucous membrane exposures, contamination of clothing, and transfer of microorganisms to other patients and environments.

• Ensure that single-use items are discarded properly. • Reusable equipment should be decontaminated after use.

Environmental hygiene:

Cleaning and disinfection of the environment: Concurrent cleaning – all surfaces should be cleaned using the approved disinfectant.

Terminal cleaning – after discharge of the patient with infection, room should be disinfected using approved disinfectant.

Care of Linen:

Used linen is potentially an infection risk especially if it is contaminated with blood or body fluid substances.

Handle, transport, and process used linen soiled with blood, body fluids, secretions, and excretions in a manner that prevents skin and mucous membrane exposures and contamination of clothing, and that avoids transfer of microorganisms to other patients and environments Render the linen “safe” by heat disinfection (usually the linen is thermally disinfected at the highest temperature the material will withstand 65º C for at least 10 minutes or 71 º C for at least 3 minutes).

Patient Placement

• Place a patient who contaminates the environment or who does not (or cannot be expected to) assist in maintaining appropriate hygiene or environmental control in a private room. • If a private room is not available, consult with infection control professionals

Screening and Immunization:

New Employees:

All new employees are screened by Staff Clinic for Hep B and HIV. Chest X-ray will be done to rule out pulmonary Tuberculosis.

New employees in high risk areas - Nasal screening done.
