Unsafe disposal Reuse of equipment Unsafe collection Injection Safety: Definition • No harm to the recipient • No harm to the health-care worker • No harm to the community Challenges
Injections given with sterile and unsafe equipment worldwide Global Burden of Disease, 2000
Determinants of unsafe injection practices in immunization services • System incentive to achieving high coverage • Vaccine usually funded through donors or lenders • No system incentive to achieve safe injections • Injection equipment is not costed, budgeted, or funded • “The sterilizable policy” smoke screen • Perception of injection safety as a “logistics” issue rather than a prevention policy issue
Reuse of disposable injection equipment Injection preparation table, Pakistan, 1995
No reuse of disposable injection equipment,other breaks in safety Injection preparation table, Romania, 1998
Injection safety beyond the use of new, disposable injection equipment • Theoretical rationale • Experience from the dialysis environment • Persistence of HBV in the environment • Ecological evidence • HBV and HCV infection among injection drug users participating in needle exchange programmes • Association between injection and HBV infection in 1998 in Romania despite the absence of reuse of equipment • Analytical studies • Association between “indirect sharing” and HBV infection among injection drug users * * Bialek S. et al. US CDC EIS conference, 2001
Proposed model for the transmission of HBV in various healthcare setting Outpatient setting in low prevalence area Dialysis setting High risk Low risk ? Prevalence of infection ? Exposure to blood ? Percutaneous exposures ? Prevalence of patients with high viremia
World: 35%, N= 22.5 million Proportion of new HBV Infections attributable to unsafe injections, 2000
Patient with cirrhosis in Africa Hepatitis B virus infection prevention • Two prevention axis • Immunization of infants(child cohorts) • Prevention of exposure to the virus, including injection safety(older age groups) • One common goal for GAVI • Protecting the adult who is in every child
World: 55%, N= 2.7 million Proportion of new HCV infections attributable to unsafe injections, 2000

Injection safety in immunization services • Challenges • Unsuccessful past efforts • History of narrow, technology oriented approach • Costs of injection safety initiatives • Conflict between the safety and coverage objectives • EPI cannot be responsible for the safety of all injections • Opportunities • Successful comprehensive approaches • Increasing recognition of holistic strategies • Promotion of responsible budgeting for EPI • Documentation of safe immunization coverage • EPI can spearhead and catalyse injection safety efforts
