2: Infection Control Overview - HIV Slide 3 Discussion: Hepatitis B Immunisation Are you familiar with the current policy for Hep B vaccination before and after exposure? What is the procedure involved for a new hospital employee under this policy? What are the contraindications for the Hep B vaccination?

2: Infection Control Overview - HIV Slide 4 Protecting Yourself from Blood-Borne Pathogens

2: Infection Control Overview - HIV Slide 5 Protecting Yourself from Blood-Borne Pathogens (cont’d) Wear gloves Don’t recap needles Complete 3 doses of Hep B vaccine Eliminate unnecessary injections Dispose of sharps immediately after use to minimise handling that increases risk of needlesticks Substitute safer devices or tools whenever possible Report needlesticks

2: Infection Control Overview - HIV Slide 6 Protecting Yourself from Blood-Borne Pathogens (cont’d) Which pathogen is most likely to be transmitted from a needle used on an infectious patient?  HIV  HEP B  HEP C

2: Infection Control Overview - HIV Slide 7 HIV: 3 Infections per 1,000 Sticks with a HIV+ Needle

2: Infection Control Overview - HIV Slide 8 Hepatitis C: 18 Persons per 1,000 Needle-sticks

2: Infection Control Overview - HIV Slide 9 Hepatitis B is Most Infectious

2: Infection Control Overview - HIV Slide 10 Why is Hep B Virus More Infectious than HIV? Viral concentration per mL Virulence factor Incubation period

2: Infection Control Overview - HIV Slide 11 Protect Yourself! Get a Hepatitis B Vaccination and keep your Vaccine Record 3 doses of Hepatitis B vaccine protect most people for a lifetime The next dose at this facility will be given on _______________ Will you be there with your staff?

2: Infection Control Overview - HIV Slide 12 Prevention of Injury Due to Sharps is Critical In some hospitals in India, staff report 1-2 sharps injuries per person per year Do you know how, when, with what device and to whom most sharps injuries occur?

2: Infection Control Overview - HIV Slide 13 Exercise 2.1: Sharps Injury Role Play Instructions: Divide into groups of 5 Decide who will play the roles of supervisor, health worker, and observer The health care worker will pretend that they have just received a sharps injury The supervisor should interview the worker about the injury using worksheet 2.1 as a guide The observer will report back to the larger group on what took place

2: Infection Control Overview - HIV Slide 14 Discussion: Sharps Reporting Form Is this Proforma sufficient for reporting sharps injuries? Why or why not? What changes could be made to current reporting procedures to make it easier to report injuries? Why do you think injuries are not always reported?

2: Infection Control Overview - HIV Slide 15 What do We Mean by “Sharps” Needles and syringes Glass capillary tubes Glass ampoules Vacutainer needles Suture needles, IV introducers and IV flushes Test tubes and glass apparati used in lab

2: Infection Control Overview - HIV Slide 16 Eliminate Needle use When Possible Do not use an injection or IV medicine when an oral medicine will do! Do not place a venting needle into an IV; this increases the risk of contamination and needlesticks

2: Infection Control Overview - HIV Slide 17 Substitute Metal or Plastic for Glass when Possible Staff are discussing using metal tubes for pulmonary drainage rather than glass to help prevent accidents

2: Infection Control Overview - HIV Slide 18 Sharps Injuries are Likely to Occur… During recapping needles During blood draws During IV insertion & removal When handling needles (taking them apart, picking up a dirty syringe, dumping containers, etc.) When disposing of sharps During waste collection and processing During breakages

2: Infection Control Overview - HIV Slide 19 Safe Handling of Sharps Wear gloves when drawing blood or handling sharps—double glove for surgery Don’t recap! Don’t bend or break needles Never place used sharps on tables, beds, furniture Put used sharps immediately into a sharps container

2: Infection Control Overview - HIV Slide 20 Disposal of Sharps: The Ideal Immediately after use, put sharps in a leak- proof and puncture- proof container The container should be within arm’s length

2: Infection Control Overview - HIV Slide 21 Sharps Disposal at GHTM Needle destroyer Disposal of sharps in blue bins What are some potential problems with the current sharps disposal system?

2: Infection Control Overview - HIV Slide 22 Sharps Disposal (cont’d) Disposal containers should be placed at all points of use Disposal bin should be rigid and should be leak and puncture proof Separate sharps from other waste so laundry workers or waste disposal staff do not get needlesticks Empty sharps containers when they are ¾ full

2: Infection Control Overview - HIV Slide 23 Danger! Open containers of used needles like this put staff at risk each time they put a hand in to pick up one Keep your ward free of used sharps

2: Infection Control Overview - HIV Slide 24 Remember this Procedure… If a needle pricks you or blood and/or body fluids enter your eye(s) or mouth  Wash wounds with soap and water  Flush eyes and mouth with water  Check the patient record to see if the patient is HIV+, HIV-, or untested  Check patient record for Hepatitis B or C infection  Call the medical duty officer immediately

NACO PEP Guidelines

2: Infection Control Overview - HIV Slide 26 Determination of Exposure Code

2: Infection Control Overview - HIV Slide 27 Determination of HIV Status Code

2: Infection Control Overview - HIV Slide 28 Determination of PEP Recommendation EC HIV SCPEP Recommendation 11 Pep may not be warranted 12 Consider basic regimen Exposure type poses a negligible risk for HIV transmission 21 Recommend basic regimen Most HIV exposures are in this category; no increased risk for HIV transmission has been observed but use of PEP is appropriate 22 Recommend expanded regimen Exposure type represents an increased HIV transmission risk 31 or 2 Recommend expanded regimen Exposure type represents an increased HIV transmission risk UNKNOWN If the source, (in the case of an unknown source), the setting where the exposure and the EC is 2 or 3, consider PEP basic regimen

2: Infection Control Overview - HIV Slide 29 HIV Testing and Counselling Post exposure HIV testing done at intervals of immediately, at 6 weeks and 6 months accompanied by Pre-test counselling Post test counselling

2: Infection Control Overview - HIV Slide 30 Drugs Recommended for Post Exposure Prophylaxis Zidovudine – 300mg 12 hrly Lamivudine – 150 mg 12 hrly Indinavir – 800 mg thrice daily ( expanded regimen only) For 28 days

2: Infection Control Overview - HIV Slide 31 Treatment for HIV after Needlesticks (Post Exposure Prophylaxis) It is most effective if started 1- 2 hours after exposure Can be given up to 72 hours after exposure Should NEVER be given without medical follow-up and filing an incident report because of the serious side effects, and the need to try to prevent similar injuries Must be taken for 28 days Pregnant staff can take PEP drugs. Tell the duty officer if you might be pregnant so he can give appropriate medications Staff member on PEP should avoid sex or practice safe sex (use condoms)

2: Infection Control Overview - HIV Slide 32 Group Discussion: Help the Infection Control Committee What is the current PEP policy and practice at your facility?  How soon after an injury should it be reported?  What do you describe a significant exposure? How should the confidentiality of the test report be maintained? Where should an emergency stock of PEP drugs be stored? Should the source patient be tested?

2: Infection Control Overview - HIV Slide 33 NACO PEP Policy - Role of the Medical Officer Decides if PEP is needed Tests the source patient and staff for HIV, if test results are not available Tests staff members who take PEP at six and 12 weeks for HIV, and monitors for side effects Gives reporting form to the Superintendent Keeps all information confidential

2: Infection Control Overview - HIV Slide 34 When do you need to wear gloves? Discussion: Personal Protective Equipment

2: Infection Control Overview - HIV Slide 35 Gloves Wear clean gloves when handing blood or body fluids Wear clean gloves when serving food Wear sterile gloves when handling sterile supplies, doing invasive procedures, suctioning, catheters, etc. Wear surgical gloves for surgery

2: Infection Control Overview - HIV Slide 36 Utility Gloves Utility gloves are used repeatedly and have many germs Do not use them to touch patients, patient care items, or anything near patents Use the same utility gloves for the same tasks - use separate gloves for dirty and clean tasks Utility gloves must be washed with detergent and bleach and left to dry at the end of the shift

2: Infection Control Overview - HIV Slide 37 Summary: Steps to Protect Yourself from Blood-Borne Pathogens Wear gloves Don’t recap needles Complete 3 doses of Hep B vaccine Eliminate unnecessary injections Dispose of sharps immediately after use to minimise handling that increase risk of needlesticks Substitute a safer substance or tool whenever possible Report needlesticks immediately

2: Infection Control Overview - HIV Slide 38 Key Points HIV PEP should be in started within 1-2 hours and should be used for four weeks if needed You can help others by being a good role model Supervisors should tactfully correct staff if they are doing unsafe practices
