4.1. HCWM situation and factors
The findings indicate that a national strategy, with appropriate
regulation and policy, are the first factors to improve the governance
structures for HCWM in any country (Townend et al., 2009;
UNEP/SBC and WHO, 2004). Safe segregation of sharps is a key
priority due to their classification as highly hazardouswaste (Pruss-
Ustun et al., 2013). Indeed their segregation leads to a dramatic
reduction in the rate of sharp-related injuries (Perry et al., 2012).
Effective treatment and disposal are also critical aspects in all the
countries. Indeed even where HCWM international standards are
being met, improvements are still possible in order to reduce the
impact on public health and the environment. This is particularly
true in LMICs where treatment and disposal will become more
tightly regulated in future (Tudor, 2012).
