Injection Safety and Waste Management
Adverse Event Following Immunization(AEFI) surveillance
EPI Managers Meeting
Kathmandu, June 23-25, 2003
Burden of unsafe injections
In a year, unsafe injections may be responsible for: 8 to 16 Million cases of Hepatitis B 2 to 5 Million cases of Hepatitis C 80,000 to 160,000 cases of HIV
EPI injections represent 10% all injections
INJECTION SAFETYINJECTION SAFETYKey stepsKey steps to improve safety to improve safety
Use of safe injection equipment Adequate injection technique
Disposal of used sharps in safety boxes Appropriate waste management
WHO/UNICEF/UNFPA joint statement
WHO, UNICEF,UNFPA urge that, by the end of 2003, all countries should use only auto-disable syringes for immunization
Campaigns: Auto-Disable (AD) Syringes
Eliminate the risk of infection between vaccine recipients
• Do not eliminate risk of needle stick injuries for health care workers • Do not solve potential infection of community
Not just AD syringes and safety boxes
Proper equipment is necessary, but not sufficient
Careful planning/budgeting/training needed
Injection safety: need for training
Preventing needlestick injury Do NOT recap needles
Do NOT bend needles
Do NOT manually remove needles from
syringes
Do NOT transport without sharp container
or safety boxes
MAJOR CAUSES OF UNSAFE
INJECTIONS
Ignorance of health-workers, consumers and the community at large
Poor/No supervision on safe injection practices
Inadequate supplies of syringes & needles Poverty- leading to re-use/resale of used
syringes and needles Campaign: time pressure
Waste management
Waste management is a frequently overlooked component of EPI: often neglected in planning, budgeting
Ultimate solution: development of jet-injectors, aerosols, powders
Assuring safe disposal of used injection material from campaigns
• In communities, with weak waste mgmt systems, campaign acutely and severely exacerbates this n acutely and severely exacerbates this chronic problemchronic problem
• Early planning necessary to identify options and develop achievable plans
Options for disposing of used injection material during campaigns
Burial Open burning and burying High temperature incineration Dumping in pit latrine or other secure pit Transport for off-site treatment New technologies/recycling
No “one-size-fits-all” solution, need local assessment, simple local solutions
WHO priority for all countries to establish and maintain AEFI
surveillance
AEFI definition: ANY adverse event that is TEMPORALY associated with immunization
AEFI
Adverse reaction to the vaccine or its components
Programmatic (human) error: more common
Coincidental
Adverse reactions associated with the vaccine
Local reaction at injection site: 0-2 days: common
Fever and rash in 5-15% of vaccinees, usually 7-12 days after vaccination, lasts 1-2 days
Encephalopathy < 1/1,000,000 doses
Thrombocytopenia <1/30,000 doses
Anaphylaxis 1 per 100,000 to 1 per million doses
Programmatic errors
Non-sterile injections Incorrect vaccine preparation Injection in wrong site Incorrect vaccine transport and storage
Abcesses, cellulitis Toxic Shock Syndrome Bloodborne infections
AEFI rates: Campaign Different from Routine
Real rise in adverse events may occur through programmatic errors (overworked health workers)
Apparent rise Large number of doses over a short period of time Better surveillance
Campaign targets different age groups than routine immunization
Media more alert
Planning a campaign
1) Planning to prevent programmatic errors
2) Establish AEFI surveillance to monitor safety of your campaign
3) Have communication plan
1. Planning to prevent programmatic errors
Use only quality vaccine (WHO-licensed), bundled with AD syringes and safety boxes
Ensure proper distribution of vaccine, diluent and injection supplies
Keep track of vaccine lot distribution
1. Planning to prevent programmatic errors
Training proper reconstitution and administration proper handling of reconstituted vaccine
Plan for safe waste disposal
2. AEFI Surveillance
Planning Case definitions for reporting Reporting channels (e.g. phone and/or fax,
messenger) Reporting, investigating forms, AEFI line list
Analyze data quickly Provide feed back on weekly basis Consider creating a review committee
3. Communication
Prepare information leaflet for parents / caretakers Prepare Qs and As for health care workers Designate focal person for AEFI surveillance
EPI manager and MoH spokesperson should be immediately informed of situation/allegations
Be ready to respond to national and international media
Ensure coordination among partners
Afghanistan, 2002Nationwide measles campaign10.2 children vaccinated (6 mo -12 yo)Was the campaign safe?
Northeastern Province: cluster of abcesses
End of September, for 14 days: measles campaign conducted in the district
3 weeks later, NID monitors “discovered” cluster of abcesses in a few villages
10 days later: MOPH/UNICEF/WHO investigation team
Investigation results
150 children (all ages) with fever and abcesses on arm in 4 villages; no death; same team vaccinate children
Average time from vaccination to symptoms/signs: 2.7 days
Team run out of diluent
“Sterile” water bought at local market to replace missing diluent
Improper vaccine reconstitution: “sterile water” bought at the local market
Consequences
Vaccinator in hiding, villagers threatened to kill him
SCA health clinic: vaccinated 100 children /month before campaign;after campaign: 8/month
Potential to derail immunization program
Programmatic errors leading to cluster of 150 abscesses
Inadequate supply: not enough diluent
Improper reconstitution, incorrect and contaminated diluent; use of same needle and syringe to reconstitute vaccine
Time constraints/ staff under pressure
Lack of supervision
Delayed reporting: no AEFI monitoring
MOPH/UNICEF/WHO Response
Investigation team
Medical follow-up provided to all
Re-training of vaccinators
Social mobilization of influential community members to restore confidence in vaccines
MOPH: Guidelines AEFI reporting and investigating, national policy, strategy and plan of action
