Subject: Disposal of UNUSED vaccine vials
To: Technet Moderator
Dear Allan,
After a review of WHO guidelines for waste disposal, we remain confused as
to the best practice for disposal of UNUSED vaccine vials/ampoules. (To be
destroyed either because of expiry or cold chain failure.) The vaccines in
question are: freeze-dried BCG & Measles, OPV, DPT, DT, and TT.
Should such sealed vials be incinerated (>1400C) or encapsulated?
best regards,
EPI East Timor

Dear James,
I've forwarded your message on EPI waste disposal to Umit Kartoglu at
WHO/V&B/ATT in Geneva for a response.
Incineration at 800'C is the recommendation as I recall - but as you know -
the vials will explode and do present a hazard - either to the incinerator
or the operators. Lower temp burning - if it is complete and long enough
duration - is probably just as effective. Let us see what Umit answers.
Immunization waste management is a real problem without really good
solutions at this point in time.

Subject: RE: Disposal of UNUSED vaccine vials
Date: Fri, 9 Mar 2001
Dear James,
Thank you for raising this issue. I am not aware of any specific WHO
recommendation regarding disposal of unused/used vaccine vials/ampoules. I
also cross checked this with some colleagues in WHO Geneva and it seems that
there is not any.
The only document I found mentioning of disposal of used vaccine vials is
the "Immunization in Practice" Module 9 "After a session" page 5, reads as
follows: "Wrap empty vials, other vials and rubbish in newspaper or other
paper. Then either burry or burn them if the local government does not
collect them."
In East Timor situation (assuming that you do not have high temperature
incineration facility) the best way of disposal would be burying them. I
would also like to inform you that this issue would be addressed in a group
work to put together an aide-memoire for planners and managers on management
of wastes from immunization activities. I will keep you posted on
developments.

Umit

WHO Fact Sheet October 2000
WASTES FROM HEALTH-CARE ACTIVITIES
Health-care activities - for instance, immunizations, diagnostic tests,
medical treatments, and laboratory examinations - protect and restore health
and save lives. But what about the wastes and by-products they generate?
From the total of wastes generated by health-care activities, almost 80% are
general waste comparable to domestic waste. The remaining approximate 20% of
wastes are considered hazardous materials that may be infectious, toxic or
radioactive. The wastes and by-products cover a diverse range of materials,
as the following list illustrates (percentages are approximate values):
Infectious wastes cultures and stocks of infectious agents, wastes from
infected patients, wastes contaminated with blood and its derivatives,
discarded diagnostic samples, infected animals from laboratories, and
contaminated materials (swabs, bandages) and equipment (disposable medical
devices etc.); and
Anatomic - recognizable body parts and animal carcasses.
Infectious and anatomic wastes together represent the majority of the
hazardous waste, up to 15% of the total waste from health-care activities.
Sharps: syringes, disposable scalpels and blades etc.
Sharps represent about 1% of the total waste from health-care activities.
Chemicals for example solvents and disinfectants; and
Pharmaceuticals: expired, unused, and contaminated; whether the drugs
themselves (sometimes toxic and powerful chemicals) or their metabolites,
vaccines and sera.
Chemicals and pharmaceuticals amount to about 3% of waste from health-care
activities.
Genotoxic waste: highly hazardous, mutagenic, teratogenic1 or carcinogenic,
such as cytotoxic drugs used in cancer treatment and their metabolites; and
Radioactive matter, such as glassware contaminated with radioactive
diagnostic material or radiotherapeutic materials;
Wastes with high heavy metal content, such as broken mercury thermometers.
Genotoxic waste, radioactive matter and heavy metal content represent about
1% of the total waste from health-care activities.
The major sources of health-care waste are hospitals and other health-care
establishments, laboratories and research centres, mortuary and autopsy
centres, animal research and testing laboratories, blood banks and
collection services, and nursing homes for the elderly.
High-income countries can generate up to 6 kg of hazardous waste per person
per year. In the majority of low-income countries, health-care waste is
usually not separated into hazardous or non-hazardous waste. In these
countries, the total health-care waste per person per year is anywhere from
0.5 to 3 kg.
HEALTH IMPACTS
Health-care waste is a reservoir of potentially harmful micro-organisms
which can infect hospital patients, health-care workers and the general
public. Other potential infectious risks include the spread of, sometimes
resistant, micro-organisms from health-care establishments into the
environment. These risks have so far been only poorly investigated. Wastes
and by-products can also cause injuries, for example radiation burns or
sharps-inflicted injuries; poisoning and pollution, whether through the
release of pharmaceutical products, in particular, antibiotics and cytotoxic
drugs, through the waste water or by toxic elements or compounds such as
mercury or dioxins.
Sharps
Throughout the world every year an estimated 12 000 million injections are
administered. And not all needles and syringes are properly disposed of,
generating a considerable risk for injury and infection and opportunities
for re-use.
Worldwide, 8-16 million hepatitis B, 2.3 to 4.7 million hepatitis C and 80
000 to 160 000 HIV infections are estimated to occur yearly from re-use of
syringe needles without sterilization2. Many of these infections could be
avoided if syringes were disposed of safely. The re-use of disposable
syringes and needles for injections is particularly common in certain
African, Asian and Central and Eastern European countries.
Regarding injection practices, public health authorities in West Bengal,
India, have recommended a shift to re-usable glass syringes, as the disposal
requirements for disposable syringes could not be enforced.
In developing countries, additional hazards occur from scavenging on waste
disposal sites and manual sorting of the waste recuperated at the back doors
of health-care establishments. These practices are common in many regions of
the world. The waste handlers are at immediate risk of needle-stick injuries
and other exposures to toxic or infectious materials.
Vaccine waste
In June 2000, six children were diagnosed with a mild form of smallpox
(vaccinia virus) after having played with glass ampoules containing expired
smallpox vaccine at a garbage dump in Vladivostok (Russia). Although the
infections were not life-threatening, the vaccine ampoules should have been
treated before being discarded.
Radioactive wastes
The use of radiation sources in medical and other applications is widespread
throughout the world. Occasionally, the public is exposed to radioactive
waste, usually originating from radiotherapy treatments, that has not been
properly disposed of. Serious accidents have been documented in GOINIA
Brazil in 1988 in which four people died from acute radiation syndrome and
28 suffered serious radiation burns. Similar accidents happened in Mexico
City in 1962, Algeria in 1978, Morocco in 1983 and Ciudad in Mexico
in 1983.
Risks associated with other fractions of health-care wastes, in particular
blood waste and chemicals, have been relatively poorly assessed, and need to
be strengthened. In the meantime, precautionary measures need to be taken.
RISKS ASSOCIATED WITH WASTE DISPOSAL
Although treatment and disposal of health-care wastes aim at reducing risks,
indirect health risks may occur through the release of toxic pollutants into
the environment through treatment or disposal.
Landfilling can potentially result in contamination of drinking water.
Occupational risks may be associated with the operation of certain disposal
facilities. Inadequate incineration, or incineration of materials unsuitable
for incineration can result in the release of pollutants into the air. The
incineration of materials containing chlorine can generate dioxins and
furans3, which are classified as possible human carcinogens and have been
associated with a range of adverse effects. Incineration of heavy metals or
materials with high metal contents (in particular lead, mercury and cadmium)
can lead to the spread of heavy metals in the environment. Dioxins, furans
and metals are persistent and accumulate in the environment. Materials
containing chlorine or metal should therefore not be incinerated.
Only modern incinerators are able to work at 800-1000 degree C, with special
emission-cleaning equipment, can ensure that no dioxins and furans (or only
insignificant amounts) are produced. Smaller devices built with local
materials and capable of operating at these high temperatures are currently
being field-tested and implemented in a number of countries.
At present, there are practically no environmentally-friendly, low-cost
options for safe disposal of infectious wastes. Incineration of wastes has
been widely practised, but alternatives are becoming available, such as
autoclaving, chemical treatment and microwaving, and may be preferable under
certain circumstances. Landfilling may also be a viable solution for parts
of the waste stream if practised safely. However, action is necessary to
prevent the important disease burden currently created by these wastes.
In addition, perceived risks related to health-care waste management may be
significant. In most cultures, disposal of health-care wastes is a sensitive
issue and also has ethical dimensions.
WASTE MANAGEMENT: REASONS FOR FAILURE
The absence of waste management, lack of awareness about the health hazards,
insufficient financial and human resources and poor control of waste
disposal are the most common problems connected with health-care wastes.
Many countries do not have appropriate regulations, or do not enforce them.
An essential issue is the clear attribution of responsibility of appropriate
handling and disposal of waste. According to the "polluter pays" principle,
this responsibility lies with the waste producer, usually being the health-
care provider, or the establishment involved in related activities.
STEPS TOWARDS IMPROVEMENT
Improvements in health-care waste management rely on the following key
elements:
The build-up of a comprehensive system, addressing responsibilities,
resource allocation, handling and disposal. This is a long-term process,
sustained by gradual improvements;
Awareness raising and training about risks related to health-care waste, and
safe and sound practices;
Selection of safe and environmentally-friendly management options, to
protect people from hazards when collecting, handling, storing,
transporting, treating or disposing of waste.
Government commitment and support is needed to reach an overall and long-
term improvement of the situation, although immediate action can be taken
locally.
Health-care waste management is an integral part of health-care, and
creating harm through inadequate waste management reduces the overall
benefits of health-care.
WHO'S RESPONSE
The first global and comprehensive guidance document, Safe Management of
Wastes from Health-Care Activities, released by WHO in 1999, addresses
aspects such as regulatory framework, planning issues, waste minimization
and recycling, handling, storage and transportation, treatment and disposal
options, and training.
It is aimed at managers of hospitals and other health-care establishments,
policy makers, public health professionals and managers involved in waste
management. It is accompanied by a Teacher's Guide, which contains material
for a three-day workshop aimed at the same audience.
The Interagency Guidelines for the Safe Disposal of Unwanted Pharmaceuticals
in and after Emergencies provide practical guidance on the disposal of drugs
in difficult situations in or after emergencies are also available.
The full text of these publications is available on the WHO web site:
http://www.who.int/water_sanitation_health under "health-care wastes".
Planned WHO products and activities include:
- The publication of a decision-maker's guide for health-care waste
management in primary health care centres;
- The implementation of health-care waste systems at country level;
- The development of a database on practical options for health-care waste
management, mainly targeted at developing country situations (soon on
http://www.healthcarewaste.org/);
- Testing of low-cost options for health-care waste management;
-The development of guidance for the disposal of blood and blood bags;
- An approach for promoting the use of products in health-care activities
leading to reduced production of wastes or less harmful wastes.

2. GAVI DONATIONS - INJECTION WASTE DISPOSAL Continued
In Technet Post00334, GAVI DONATIONS - INJECTION WASTE DISPOSAL, on 10 April
2001,
John Lloyd, PATH/CVP, Ticky Raubenheimer, CCCCM/SA/CSIRO, and Anthony
Battersby, FBA Analysts, have kindly posted an interesting discussion on the
GAVI/CVP supported addition of new vaccines and immunization system
strengthening - WHICH ADDS a lot of hazardous materials to the volume of
injection waste in immunization programs.
Data from many countries indicate that the management of immunization and
other injection waste is inadequate and dangerous to health workers and to
the public.
The key issue is that in the next year or so 7,661 cubic meters of
immunization injection waste is being added to health systems where the
current management of health care waste in inadequate to non-existent.

Dear Allan,
We have prepared a tool for assessing the situation in a country regarding
health-care waste management. This "Rapid Assessment Tool" is available on
the SIGN web site www.injectionsafety.org. It is still in draft form, and
will remain so for about another year. It has already been field tested in
Albania and Ivory Coste, but we would like to benefit from further
experience from the field with that tool, so please send us your comments
(to [log in to unmask]).
This tool assists in drawing a picture of current practices, understanding
the level of awareness regarding risks associated with unsafe health-care
waste management, and evaluating the existing regulatory framework. It not
only assists in assessing the situation, but in addition provides the
necessary information to design an action plan on the basis of the
information collected.
It is composed of a brief introduction to the area, various questionnaires
to use with several key actors in the country (Ministries of Health and of
Environment, managers of health-care facilities, staff responsible for waste
management in those facilities etc.). It also assists in choosing a sample
of health-care facilities to visit during the assessment, and in the
planning phase of the assessment. A simple rating system assists in
evaluating the overall situation of the country regarding the safety of
health-care waste management. Finally, a glossary outlines basic terms used
in health-care waste management.
An assessment would take an estimated 3 person-weeks, including preparation
and reporting. A more thorough assessment, or assessment of a large
country, may require additional work.

FIRST, DO NO HARM
Lisa Jacobs examines the road to injection safety - from recognition of the
problem to action
YOU may already know: unsafe injection practices spread disease. In a tragic
twist of irony, health workers who aim to improve people's health may be
unintentionally spreading harm with every prick of an unsterile needle,
every time they toss a used disposable syringe in a vat of warm water for
eventual re-use, or drop it in a trash can.
The result? From 8 million to 16 million new hepatitis B infections, 2.3
million to 4.7 million new hepatitis C infections and 80,000 to 160,000 new
HIV infections every year. These chronic infections are responsible for an
estimated 1.3 million early deaths and lead to US$ 535 million in direct
medical costs every year.
Injections are prescribed for a wide variety of reasons. While they are
essential for delivery of vaccines and many treatments, they are also given
for other, questionable reasons. The belief that an injection is the most
powerful and quick way to deliver medicine - even if the syringe contains
nothing but vitamins - contributes to over-demand for, and over-prescribing
of, injections. In fact, the majority of injections given for curative
reasons in developing countries are thought to be unnecessary.
Why are unsafe injections tolerated - by health workers, patients,
caretakers, government officials? The answers are complex and include
economic imperatives and cultural attitudes about waste. But perhaps the
most important reason is that the people with decision-making power -
including patients and caretakers of children - do not understand the risks,
the extent of the problem, or that solutions (Box 1) are well within reach.
According to Dr Yvan Hutin, an epidemiologist and hepatitis B expert who
runs the Safe Injection Global Network (SIGN), understanding the problem is
the first and most crucial step.
In fact, in many cases, as soon as people see the evidence of what is
occurring, they are convinced they must do something about it, says Dr
Hutin. "The problem of unsafe injections will not solve itself. But when
safety is included in health sector plans and budgets, it will improve."
A PROBLEM WITH CLEAR SOLUTIONS
In 1995, a study in Burkina Faso found that only one in ten injections in
rural health centres was performed with sterile equipment. A new system was
then introduced that made essential drugs - including disposable, sterile
syringes - readily available at every health centre through a cost recovery
scheme. Five years later, the impact on safety was astounding: by 2000
nearly 100% of injections in the centres surveyed were given with a sterile
syringe. In this instance, increased supply of syringes led to increased
demand - a demand for which people were willing to pay.
"The Burkina Faso experience shows how incredibly amendable this problem
is," said Dr Hutin. "Sometimes it is just a matter of making clean needles
available."
The supply, or logistics, approach that worked in Burkina Faso will not be
the answer for all countries. Demand led to supply in Romania, where a
highly publicised outbreak of HIV infections occurred among orphans in the
early nineties. Children had been infected through blood transfusions and
injections conducted in orphanages.
With the vivid images of medically-induced HIV infection, concern about
contracting diseases from syringes built among the general public. People
demanded new syringes, in sealed packages, for every injection, and the
system responded.
"Every time an intervention has been funded and attempted, regardless as to
whether it was behaviour change, provision of supplies or sharps waste
management, it showed some impact," says Dr Hutin. "So if we have a sector
wide approach that combines all these low-cost interventions, we should be
able to eliminate unsafe injection practices."
EPI: A SMALL PART OF THE PROBLEM, A BIG PART OF THE SOLUTION
Even though immunization injections account for fewer than 10% of the 12
billion injections given annually, most health systems have considered
injection safety the responsiblity of the immunization programme, or EPI.
Unfortunately, that responsibility has not been supported with appropriate
budgets. And even though it is essential that immunization programmes have
safe practices, EPI managers have no control over the use and over-use of
injections in the greater health system.
"We can't solve the problem," says Dr Caroline Akim, EPI Manager in
Tanzania. "But we can act as advocates, and push the health system to
address it." In fact, advocating for safe injection policies and practices
is an opportunity for immunization programmes to have a profound, system-
wide impact.
The first priority, according to many, is to adopt a policy on safe
injection and disposal. "Having a system-wide policy is necessary to extend
responsibility for injection safety to the whole health sector, instead of
just in EPI," says Dr Akim. A national policy also gives programmes the
authority to seek out and put an end to actions that are unsafe.
However, a policy is only as good as its implementation. Without buy-in by
all stakeholders, a safe injection and disposal policy will just be another
rule on the books - one that may be considered a nuisance, adding costs to
programmes and perhaps even depriving people of much needed income.
"A policy that is not followed is just like having no policy at all," said
Dr. B. Wabudeya, Minister of State for Health in Uganda. And the danger is
that those in roles of responsibility may think that once a policy is
drafted and adopted, the situation has been addressed.
MEASURING THE PROBLEM
If discovery is the first step toward solving the problem, the first step
has just been made easier. A simple, focused methodology for tracking
injection and disposal practices, and documenting knowledge and
understanding among health workers and patients, has just been developed
jointly by SIGN, the World Health Organization and BASICS, a programme
funded by the US Agency for International Development. Referred to as 'Tool
C' (as in, third of a series of four), this new methodology has been tested
in Burkina Faso, Niger, Ethiopia, Mali, Mauritania, Zimbabwe and Egypt(1).
The aim is to make it as easy for governments to monitor injection safety as
to monitor the percentage of all children immunized, or coverage. "What is
the good of increasing coverage if you also increase exposure to hepatitis B
and C, or HIV?" asks Hutin.
The methods behind Tool C are simple. In each country, a team of 12 monitors
activities in 80 health centres in 10 districts over 2 weeks. Importantly,
the data collected are practical, so countries can quickly identify
solutions. For example, the team finds out how many health centres have
dedicated areas for the preparation of injections, and whether they have at
least a week's supply of disposable/AD equipment in stock. The measures are
standardized, so, as more countries undertake the process, common problems
can be highlighted and appropriate actions designed.
DANGEROUS WASTE
Tool C identified a serious problem in Burkina Faso, one that has caught
many communities unprepared. Investigators found needles discarded in open
containers in 66 health centres, putting health workers at risk of
accidental needle-stick injuries. At most of the centres, used needles and
syringes were found in the surrounding environment, putting the larger
community at risk - a situation that has been identified in a number of
countries.
"In many developing countries, collection and removal of waste is considered
to be a municipal responsibility - not that of the hospitals and health
system," says Annette, from the environmental safety division at WHO.
"The concept of 'polluter pays' is a very Western concept."
Not only do children find syringes to be effective squirt toys; in many
countries, scavengers also scour refuse for saleable items. Conventional
disposable syringes can be rinsed, re-packaged and re-sold as new, when they
are not in fact sterile. According to environmental experts, some health
workers actually collect used syringes to sell to recyclers, providing
income for both. And risk for many.
Now, having learned of their waste disposal problem, health officials in
Burkina Faso have developed plans to address it. Their chances for success
are high; a recent assessment in Ivory Coste found that facilities which
took responsibility for healthcare waste as part of their duty of care
successfully eliminated dirty sharps from their environment.
"What is needed above all is the will to take care of the problem," says Dr
Hutin.
TECHNOLOGY TO THE RESCUE?
Many countries are addressing injection safety by making the switch to AD
syringes for immunizations. AD syringes have a mechanism designed to lock
the syringe once it is used, so that it cannot be re-used. Countries that
have been approved to receive vaccines from GAVI and the Global Fund will
also receive the requisite number of AD syringes. GAVI is now weighing a
policy to further help countries with the transition from sterilizable
and/or disposable syringes to AD syringes for all vaccines, in order to
support countries to comply with the policy of WHO, UNICEF and UNFPA to use
AD syringes for all immunizations by 2003.
But when it comes to safety, technology is not the entire solution. "If you
want to learn how to re-use an 'auto-disable' syringe, come to Pakistan,"
says Johnny Thaneoke Kyaw-Myint, Senior Project Officer for Health and
Nutrition with UNICEF Pakistan. He was, of course, not serious. "People have
learned how to manipulate the syringe so that the safety mechanism doesn't
catch. So it can be re-used, or sold and re-used, again."
The lesson? People must be educated, motivated and supported to insist upon
a sterile syringe with every injection. Provision of safe injection
equipment should be part of a broader strategy that also includes
encouraging behaviour change and the management of sharps waste.
At present, 500 million AD syringes are produced annually for use in
developing countries. Within two years, as more and more countries follow,
that number is expected to rise to 2 billion. The disposal issue becomes
more critical each day.
Simple actions can be taken immediately, says Dr Annete. Supplies of sharps
boxes should be available in all health centres - not just in time for
immunization campaigns. Small incinerators can be built; local oven-builders
can be employed to build incinerators. The costs are affordable; a small
incinerator to serve a district can be built for under US$700, according to
Dr John Lloyd, an immunization expert with the Bill and Melinda Gates
Children's Vaccine Program at PATH.
Until recently, the problem of unsafe injections seemed insurmountable, says
Dr Hutin. "But in fact, when one looks at the experience acquired, we now
know that safety is an area that is easy to address - if the health system
decides to address it. We know some simple strategies to follow, and results
are visible and quick."

Country file 1: Pakistan - a country ready for change
SOME would be daunted by the scale of the challenges facing Pakistan's newly
formed injection safety network. But Dr Arshad Altaf, one of the key
organisers of the network, does not sound like the daunted type.
"There are no short cuts; we need education and training, and we need
injection safety to get the attention and priority that it deserves," says
Dr Altaf, a medical doctor and behavioural epidemiologist from the Aga Khan
University in Karachi.
The burden of bloodborne infections in Pakistan is heavy. As many as one in
ten of the general population is a chronic carrier for hepatitis B virus
(HBV). And, in the past few years, hepatitis C virus (HCV) has spread
rapidly; in some parts of Pakistan, more than one in 20 people are chronic
carriers. Researchers have concluded that unsafe injections are the most
likely cause of this growing HCV epidemic. And since HCV is even more likely
than HBV to cause chronic liver disease, the burden of long-term illness is
rising.
UNNECESSARY INJECTIONS
Studies in Hafizabad, southwest of Lahore, and Darsano Channo, near Karachi,
both found that exposure to injections was the strongest risk factor for
being infected with hepatitis; the more injections, the greater the
probability of being infected(1).
"Painkillers, antibiotics, antimalarials, steroids and multivitamins are all
given by injection," says Dr Altaf. All at a price: patients often pay 30
Pakistan rupees (about US $0.50) for an injection when the whole household's
income is often as low as US$1.60 a day. "When the supply of syringes runs
out, the clinics just dip the syringe in water and re-use it," says Dr
Altaf.
In a study at Aga Khan University Hospital, Dr Naheed Nabi and others(2)
found that most patients believed injections were more effective than oral
medications, and were willing to pay more for them. But when told that oral
medications are equally effective, four-fifths of patients said they would
prefer to avoid an injection.
Interestingly, 91 per cent of the patients who received injectable
treatments said that their doctors recommended them, disputing the claim
that health workers are merely responding to demand. Only 9 per cent of
patients had requested injections.
RECYCLED SYRINGES
A further problem is waste disposal. "There is no proper management or
disposal system for waste," says Dr Altaf. His team have tracked the final
destinations of syringes from hospitals and clinical laboratories in
Karachi. Many are dumped at community waste sites where scavenger boys
collect them and sell them to dealers. Some are also sold to scavengers by
cleaners at the clinics and labs.
"The used syringes with needles are sold by the kilogram at up to 10
Pakistan rupees [17 US cents]," says Dr Altaf. Needles are removed by the
dealers and are re-moulded. The syringe plastic is washed, crushed and made
into granules, which are sold on to the plastic ware industry. A minority of
syringes are also repackaged and sold for repeat medical use.
The earnings from the hazardous trade of recycling used syringes might seem
small to comfortable outsiders sitting in the industrialized countries. But
to people on low incomes, they are significant, says Dr Altaf. "With the
financial incentive and the culture of re-use being so ingrained in the
country, we expect that recycling will continue," he says.
EDUCATE THE SCAVENGERS
Pakistan must develop a proper system(3) for clinical waste disposal, Dr
Altaf believes. This, together with the eventual use of autodisable (AD)
syringes in the country's immunization clinics, may reduce the risks of
bloodborne infections. But until doctors and patients gain a greater
understanding of the risks of infection, and the number of unnecessary
therapeutic injections falls, large numbers of conventional disposable
syringes will continue to enter community waste dumps. Dr Altaf believes
that it may be pragmatic to educate those involved in the recycling trade
about the risks of infection and create a reliable system for the safe
removal and incineration of needles before the syringes are put in the
trash. If the recycling of syringes for remoulded plastic cannot
realistically be stopped yet, at least the risks to everyone can be reduced.
In the short year since Pakistan formed its national network for the Safe
Injection Global Network, no time has been wasted. Today, the network's
activities are beginning to bear fruit: the country has recognized the scale
of its problem and - crucially - most stakeholders in the health system are
now keen to do something about it.

Country file 2: Egypt: 'We need to decrease the demand for injections'
EGYPT knows better than most countries the human cost of re-using needles.
An astonishingly high proportion of the population - about one in eight
people - is infected with hepatitis C virus (HCV), and hepatitis B is also
widespread(1). Much of this disease burden is attributed to unsafe
injections. The problem is not new, but today there is a new and powerful
commitment to overcoming it.
"Injection safety and infection control have become high priorities of the
Ministry of Health and Population," says Dr Maha Talaat, a public health
specialist and executive manager for a new programme in the ministry. The
programme's goal is to prevent the transmission of bloodborne pathogens in
the health service. Dr Talaat is also a member of a new national coalition
of health workers that is striving to increase awareness of injection safety
issues.
Part of Egypt's problem can be traced back to a mass treatment for
schistosomiasis before the 1980s. The treatment required multiple injections
and is believed to have spread HCV widely(2). But new cases of HCV infection
have continued to appear today, even though the schistosomiasis treatment
has long been replaced. Researchers believe that re-used needles are still
to blame. Today, studies suggest HCV continues to be spread by unsafe
injections and other healthcare practices.
Most of the injections are unnecessary. "People prefer injections to oral
medications because they think that injections will cure them faster," says
Dr Talaat. "We need to decrease the demand for injections."
The government has planned its response carefully. This year, the new
programme is gathering essential baseline data so that it can measure the
impact of interventions that will start next year, including training for
healthworkers, education and mass media campaigns for the public, and action
to ensure that supplies of sterile injection equipment are available at all
times.
The top priority, Dr Talaat believes, is to educate those who deliver the
injections. The first step is to identify who they are. The team has already
discovered, from a study in one governorate, that more than 40% of
injections in this setting are given not by trained healthworkers but by lay
people including relatives, friends and "health barbers", whose services are
cheaper than those of doctors. These findings, and further studies to find
out healthworkers' practices across the country, will be crucial in the
design and targeting of training material.
Another key priority is safer disposal systems for clinical waste, says Dr
Talaat. "The Ministry of Environmental Affairs, together with the Ministry
of Health and Population, are working to try to solve this problem," says Dr
Talaat. Because there is no proper system for the transport and incineration
of clinical waste, all syringes - whether or not they are in safety boxes -
are a hazard once they leave the healthcare facility. Some find their way to
municipal rubbish dumps where children play with them. If the final disposal
system is not properly managed, says Dr Talaat, no type of equipment,
including safety boxes or autodisable (AD) syringes, can be regarded as
safe.
No one doubts the scale of the challenge facing Egypt. But now it is
recognized. And, with a new government programme and an active coalition of
healthworkers determined to achieve change, the battle has begun.
