5 Exposure Determination Who has occupational exposure to blood and other potentially infectious materials (OPIM)?

6 OSHA Regulations BBP Standard Each employer who has an employee(s) with occupational exposure as defined by paragraph (b) of this section shall prepare an exposure determination. This exposure determination shall contain the following: Job classifications with occupational exposure to Blood and OPIM A list of all tasks and procedures or groups of closely related task and procedures in which occupational exposure occurs and that are performed by employees in job classifications listed in accordance with the provisions of paragraph (c)(2)(i)(b) of this standard. The Bloodborne Pathogens Standard (29 CFR ) ble=standards&p_id=10051

9 Post-Exposure Serologic Assessment Because vaccine-induced anti-hbs wanes over time, testing HCP for anti-hbs years after vaccination might not distinguish vaccine nonresponders from responders. NEW Giudance: Pre-exposure assessment of current or past anti-hbs results upon hire or matriculation, followed by one or more additional doses of HepB vaccine for HCP with anti-hbs <10 miu/ml, if necessary, helps to ensure that HCP will be protected if they have an exposure to HBV-containing blood or body fluids.

10 OSHA: Hepatitis B Vaccine 29 CFR (f)(1)(ii)(D) takes into consideration the changing nature of medical treatment relating to hepatitis B. OSHA requires use of the U.S. Public Health Service (USPHS) guidelines current at the time of the evaluation or procedure. The hepatitis B vaccination must be given in the standard dose and through the standard route of administration, as recommended in the most current USPHS guidelines.

11 Types of Occupational Exposures to Blood Percutaneous injury Mucous membrane exposure Non-intact (broken) skin exposure Bites

12 Evaluate Alternative Practices and Devices

13 Engineered Safety Sharps

14 Sharps Safety Devices OSHA requires employer to consider procedures and technology that reduce the risk of needlesticks Must document consideration and use of appropriate, and effective safer devices Description of devices identified as candidates Method(s) used to evaluate those devices Justification for the eventual selection (or rejection) Cannot use cost as a justification for non-selection of a safer device Non-managerial employee input must be documented but can be informal in nature

26 Postexposure Management

27 OSHA DEFINITION Exposure Incident means a specific eye, mouth, other mucous membrane, nonintact skin, or parenteral contact with blood or other potentially infectious materials that results from the performance of an employee's duties.

28 Postexposure Management Program Develop clear policies and procedures that reflect Employer Obligations un OSHA BBP Standard Current CDC Guidance Other Considerations (temporary workers, volunteers, etc.) Educate dental health care personnel (DHCP) Education and training strategies Provide rapid response following an exposure incident: Facilitate appropriate exposure response/first aid, Complete initial exposure report Refer DHCP to qualified HCP (risk assessment, baseline testing, and post-exposure prophylaxis) Document source patient and request testing for HIV, HBV, and HCV, unless +sero-status known

29 Exposure Incident Management Percutaneous Expousre Incident Remove instrument or syringe/needle Report Injury to designated on-site manager Provide exposure response first aid Complete initial report Refer exposed DHCP to qualified HCP Request source patient testing Post-exposure site specific evaluation Obtain written report from HCP

30 Do not reuse instrument or device on patient If exposure occurs with sterile item, it must be re-sterilized If accidental reuse occurs, inform patient and evaluating health care provider (occupational health physician or nurse) Remove Instrument/Needle

31 Provide Exposure Response First Aid Wound management for percutaneous exposures Eyewash for blood exposures to the eyes

32 Wound Care Dos and Don ts

33 Wash the Wound Do Wash Wound with Soap and Water Do Not

34 Do Not Do not squeeze or milk wound. Do not apply a tourniquet

35 Flush Mucous Membranes of the Eyes

36 Eye Wash Use and Maintenance

37 Elements of the Exposure Report Date and time of exposure Procedure details: where, when, how, with what device Exposure details: route, body substance involved, volume and duration of contact Information about source patient Exposure management details

38 ml/rr5011a1.htm 2001

39 Request Source Patient Testing Documentation of the source patient Where should this be documented? What information, if source is infected? What tests? (HIV, HBV, HCV) Who should do the testing? Who pays? Informed consent and patients rights What are the state specific statutes and regulations?

45 Recommended Postexposure Management: PEP for Exposure to HBV Exposed person Treatment Vaccinated Documented responder Documented Nonresponder 1 series/3 doses Documented Nonresponder 2 series/6 doses Unvaccinated/incompletely vaccinated or vaccine refusers No action needed HBIG x 1 and initiate revaccination, positive/unknown source no action if the source patient is negative for HBsAg HBIG x 2, separated by 1 month, positive/unknown source. No action if the source patient is negative for HBsAg HBIG x 1 and initiate revaccination, no HBIC if source patient is HBsAg negative

46 Management of Exposures to Hepatitis C Virus (HCV) For source patient, testing for antibodies to HCV Rapid HCV antibody test may be available. For exposed person, baseline and followup testing for anti-hcv and liver enzyme activity Immunoglobulin prophylaxis is not effective nor recommended. New HCV treatment drugs, used for acute HCV infection, are currently not recommended for HCV post-exposure prophylaxis.

47 No Recommended HCV Prophylaxis Preexposure or postexposure prophylaxis with antiviral therapy is NOT recommended. Although new antiviral treatment regimens are highly efficacious and more tolerable than IFNbased therapy, there are no data on the efficacy or cost-effectiveness of antiviral therapy for pre-exposure or post-exposure prophylaxis of HCV infection. Some studies have shown that post-exposure treatment with IFN-based regimens does not prevent infection. (Nakano, 1995 [17]); (Arai, 1996 [18])

48 Postexposure Management: Follow-up of Hepatitis C Virus (HCV) Exposed HCP Test for anti-hcv and amino alanine transferase (ALT) 4-6 months after exposure. Test for HCV- ribonucleic acid (RNA) at 4-6 weeks for earlier diagnosis of HCV infection. Confirm anti-hcv enzyme immunoassay (EIA) positive results with recombinant immunoblot assay (RIBA). Guidelines for therapy during acute HCV are to refer to a specialist for proper management. Select an HCP who follows current HCV postexposure recommendations.

49 Interpretation of Blood Testing During Diagnosis of Acute HCV Infection Test Interpretation for Diagnosis of Acute HCV Infection HCV antibody [test baseline, 4-6 weeks and 4-6 months after the exposure] HCV Ribonucleic Acid( RNA) [test 4-6 weeks after the exposure] May be negative in the first 6 weeks after exposure May be delayed or absent when the individual is immunosuppressed Presence alone does not distinguish between acute and chronic infection Low signal-to-cutoff ratio may be present during acute HCV infection or represent a false-positive result Viral fluctuations greater than 1 log10 IU/mL may indicate acute HCV infection May be transiently negative during acute HCV infection Alone does not distinguish between acute and chronic infection Alanine aminotransferase (ALT) [test 4-6 months after the exposure] Fluctuating peaks during acute HCV infection suggest acute infection May be normal during acute HCV infection May be elevated due to other liver insults such as alcohol consumption AASLD and IDSA;

51 HIV PEP Recommendations (1) PEP is recommended when occupational exposures to HIV occur; (2) the HIV status of the exposure source patient should be determined, if possible, to guide need for HIV PEP; (3) PEP medication regimens should be started as soon as possible after occupational exposure to HIV, and they should be continued for a 4-week duration; (4) new recommendation-pep medication regimens should contain 3 (or more) antiretroviral drugs (listed in Appendix A ) for all occupational exposures to HIV;

52 HIV PEP Recommendations (5) expert consultation is recommended for any occupational exposures to HIV and at a minimum for situations described in Box 1 ; (6) close follow-up for exposed personnel ( Box 2 ) should be provided that includes counseling, baseline and follow-up HIV testing, and monitoring for drug toxicity; follow-up appointments should begin within 72 hours of an HIV exposure; and (7) new recommendation-if a newer fourth-generation combination HIV p24 antigen-hiv antibody test is utilized for follow-up HIV testing of exposed HCP, HIV testing may be concluded 4 months after exposure ( Box 2 ); if a newer testing platform is not available, follow-up HIV testing is typically concluded 6 months after an HIV exposure.
