Presentation Transcript
the basis of this presentation
The basis of this presentation
  • This presentation is designed to assist with the training of staff on sharps management including safety devices
  • The information relates to prevention of hollow-bore needle stick injuries (NSI) and should be used in combination with other training material
  • The information includes the NACO guidelines concerning the Indian law/ Supreme court guidelines and other concerns.
  • The Drug regimes for Post exposure practices should be followed as per current guidelines

Dr.T.V.Rao MD

the problem
CDC estimates ~385,000 sharps injuries annually among hospital-based healthcare personnel (>1,000 injuries/day)

Many more in other healthcare settings (e.g., emergency services, home care, nursing homes)

Increased risk for blood borne virus transmission

Costly to personnel and healthcare system

The Problem

Dr.T.V.Rao MD

slide4

Exposures which place health personnel at risk of blood borne infection –

  • A percutaneous injury e.g. Needle stick injury (NSI) or cut with a sharp instrument
  • Contact with the mucous membrane of eye or mouth
  • Contact with non-intact skin (abraded skin or with dermatitis)
  • Contact with intact skin when the duration of contact is prolonged with blood or other potential infected body fluids

Work Practices which Increase the Risk of Needle Stick Injury

Recapping needles (Most important)

Performing activities involving needles and sharps in a hurry

Handling and passing needles or sharp after use

Failing to dispose of used needles properly in puncture-resistant sharps containers

what kinds of devices usually cause sharps injuries
What kinds of devices usually cause sharps injuries?
  • Hypodermic needles
  • Blood collection needles
  • Suture needles
  • Needles used in IV delivery systems
  • Scalpels

Dr.T.V.Rao MD

what infections can be caused by sharp injuries
Sharps injuries can expose workers to a number of blood borne pathogens that can cause serious or fatal infections. The pathogens that pose the most serious health risks are

Hepatitis B virus (HBV)

Hepatitis C virus (HCV)

Human immunodeficiency virus (HIV)

What infections can be caused by sharp injuries?

Primary HIV Infection

- in 81% of HCWs

- median 25 days after exposure

Seroconversion

- Median 46 days

- by 6 months in 95% of HCWs

- 3 persons Seroconversion at 6-12 months

protecting yourself
Protecting yourself …
  • Report all needle stick and sharps-related injuries promptly to ensure that you receive appropriate follow-up care.
  • Tell your employer about any sharps hazards you observe.
  • Participate in training related to infection prevention.
  • Get a Hepatitis B vaccination.

Dr.T.V.Rao MD

post exposure prophylaxis pep
It refers to the comprehensive management to minimize the risk of infection following potential exposure to blood borne pathogens (HIV, HBV, HCV ).It includes –

First Aid

Risk Assessment

Counseling

PEP drugs (4Weeks) depending upon risk assessment

Relevant Lab Investigation on informed consent of the

source and exposed person

Follow up and support

Post Exposure Prophylaxis (PEP)

Dr.T.V.Rao MD

management of exposed person
1ststep: Management of exposed site - First Aid

Skin: Do not squeeze the wound to bleed it, do not put the pricked finger in mouth. Wash with soap &water, don’t scrub, no antiseptics or skin washes (bleach, chlorine, alcohol, betadine).

Eye: wash with water/ normal saline/ don’t remove contact lens immediately if wearing, no soap or disinfectant.

Mouth: spit fluid immediately, repeatedly rinse the mouth with water and spit / no soap/ disinfectant.

Management of exposed person

Dr.T.V.Rao MD

2 nd step establish eligibility for pep
2nd step: Establish eligibility for PEP
  • Evaluation must be made rapidly so as to start treatment as soon as possible-ideally within 2hours but certainly within 72 hours of exposure. However all exposed cases don’t require prophylactic treatment.
  • Factors determining the requirement of PEP-
  • Nature/Severity of exposure and risk of transmission
  • HIV status of the source of exposure
  • HIV status of the exposed individual

Dr.T.V.Rao MD

Quick FACT:HBV vaccination is recommended for all healthcare workers (unless they are immune because of previous exposure). HBV vaccine has proven to be highly effective in preventing infection in workers exposed to HBV. However, no vaccine exists to prevent HCV or HIV infection.

Dr.T.V.Rao MD

supreme court directive to ensure pep drugs in all government hospitals in india
Supreme Court Directive To Ensure PEP Drugs in All Government Hospitals in India
  • Universal Work Precautions (UWP) and PEP guidelines should be followed by HCPs to prevent occupational transmission of HIV, Hepatitis B and hepatitis C.
  • This will develop confidence in HCPs while working with patients some of whom might be infected with HIV/HBV/HCV.
  • PEP drugs should be available in all Govt Hospitals to enable protection of HCPs dealing with potentially infected patients to make sure that no patients suffering from HIV be denied treatment/surgery/ procedures etc
  • Availability of UWP and PEP can minimize the stigma and discrimination against PLHIVs in Health Care facilities.
  • Above regulations to be practiced in Private hospitals and Establishments

Role of PEP in Preventing Transmission of HIV- Indian Studies (Contd.)

2. LTM Hospital, Sion, Mumbai -2002

Over a period of one year, June 2000 - 2001, a total number of 38 cases of accidental exposures were self reported

Of the 38 reported cases; 34 were NSIs, 2 were scalpel cuts, and 1 was exposure to body fluids (vitreous humor) by splashing and 1 was a human bite, from a psychiatric patient.

The 38 source cases were also tested for HIV 1,2 antibodies and HBsAg. Ten were HIV seropositive and 28 HIV seronegative and four were HBsAg positive and 34 HBsAg seronegative.

Majority of the 34 needle stick injuries were by hollow bore needles. Of these, 20 were during blood collection procedure by hollow bore needle, 5 during angioplasty procedure, 4 during central venous puncture line cut down procedures, 2 during suturing of contused lacerated wound and 3 while recapping the needle. PEP was received regularly by 10 cases.

All the HCWs were HIV and HBsAg seronegativee after one and half years.

availability of pep at healthcare facility
Availability of PEP at Healthcare facility

It is recommended that PEP drugs be kept available round-the-clock in any of the three locations - Emergency room, Labor room and ICU.

Drug Stock at the Healthcare facility

PEP kit comprises of 2 drug regimen:

Zidovudine(AZT) 300mg + Lamivudine (3TC) 150 mg as a fixed dose combination
