Physician groups lobby European Union to reduce sharps injuries

LEADING European physician groups are pressing the European Union to reduce the number of injuries from needles and other sharps.
Infection with
contaminated sharps
represents major hazard


A number of national and international groups warn that infection from contaminated sharps continues to pose a major risk to surgeons and other health professionals.

World Health Organisation
“Contaminated needles and syringes, accidentally or intentionally, are potentially causing many millions of hepatitis B virus infections and many thousands of human immunodeficiency virus infections each year, particularly in the developing countries. The cost to society of the treatment of disease caused by an unsafe injection is thought to be equivalent to about 22 cents US per injection – considerably more than the cost of preventing disease caused in this way.”

International Sharps Injuries Prevention Society
“There are more than 100,000 needle stick injuries in UK hospitals each year. Needle stick injuries are virtually undocumented in many developing countries, but probably equal or exceed those in the industrial world.
“Healthcare workers worldwide are concerned about these accidental needle sticks and other sharps injuries resulting in life-threatening infections. Far too often, healthcare workers are becoming patients after being injured by contaminated medical sharps. These health care workers are contracting potentially deadly infections from sharps injuries that are largely preventable. Health care workers from other disciplines have received sharps injuries including: surgeons, anaesthesiologists, cleaning staff and house-keeping staff.”

UK Medical Devices Agency
“The problem of needle stick and sharps injuries remains a major issue. The cause of these injuries is not restricted solely to the use of needles but also involves other medical devices, surgical instruments, bone fragments and glass vials. These injuries carry the risk of transmission of blood borne viruses.
“In all cases emphasis should be placed on the correct handling before, during and after use and the safe disposal of such devices. Appropriate training of staff is essential in reducing the risks of needle stick and sharps injuries. However it is possible for needle stick and sharps injuries to occur as a result of accidents and the risk associated with these may be reduced by the use of devices incorporating safety features developed during the design of the devices.”

US National Alliance for the Primary Prevention of Sharps Injuries
An estimated 800,000 medical sharps injuries occur each year in healthcare facilities across the US. alone. At risk is any health care worker who handles sharp devices or equipment such as lancets, suture needles, scalpels, or hypodermic needles.

Emergency Care Research Institute
“Any time a needle is used, the potential for a needle stick injury exists — either during or after use or during or after disposal. Injuries that occur after use – for example, if a needle is accidentally left in bed linens – and those that occur after disposal – for example, if exposed needles are protruding from an overfilled sharps container – can be especially problematic.
“In these cases, it is unlikely that the injured person or subsequent caregivers will be able to identify the source patient. As a result, they won't know crucial information about the contamination status of the needle. Because the prudent response in such cases is to assume that the needle had been contaminated, these injuries can lead to unnecessary anxiety and treatment expenses.
“By eliminating needles whenever possible, you'll not only eliminate the risk of injury to the user, but you'll also eliminate the possibility of injuries occurring after the needle has been discarded”.

The call follows increasing fears among surgeons, including ophthalmologists, about the risk of contracting hepatitis and HIV through needle-sticks during surgery.
In a new manifesto, the European Medical Association and European Institute of Medicine have joined nursing, industry and patient groups to press the EU to ensure:

• Consistent compliance with existing EU Worker Safety and Health Directives among EU healthcare providers
• Better information and education of physicians and other health care workers about the
risks of exposure, prevention methods and effective incident reporting
• Safer working practices, including better use of protective clothing, safer disposal of sharps and more effective responses to sharps injuries
• Use of “Sharps Protection” Technology especially for high-risk medical procedures.

“Injuries caused by needles and other sharp medical devices and the related risk of potentially fatal disease transmission remain a major threat to the health and safety of health care workers across the European Union today,” reads the manifesto, which was originally drafted by EUCOMED, the European Medical Technology Industry Association.

In addition to the two physician groups, five other groups to date have signed on to the manifesto: the European Dialysis and Transplant Nurses Association/European Renal Care Association; the International Alliance of Patients' Organisations; the European Federation of Public Service Employees; and the Standing Committee of Nurses of the European
Union.

Studies cited by manifesto indicate that:
• Surgeons, like any other health care workers who regularly work with such sharp instruments as scalpel blades and suture needles, face a high risk of contracting hepatitis B, hepatitis C and even HIV through jabs and sticks when treating infected patients
• The primary route of infection is by percutaneous injury from blood-filled needles
• Hospital staff members incur as many as 30 needlestick injuries per 100 beds each year. However, it is estimated that between 60% and 80% of incidents go unreported.
The risk of infection from a contaminated sharp, of course, depends on the pathogen.

Studies indicate that the risk of transmission of infection from an infected needle is:

• one in three workers for hepatitis B
• one in 30 for hepatitis C
• one in 300 for HIV

The EU debate over needle-stick injuries follows a similar debate in the United States.

There, the US Centre for Disease Control estimates that between 62% and 88% of sharps injuries could be prevented by specific safety features for handling the medical device or preventing accidental pricking.
Against such a background, the American Congress enacted a special law, the Needlestick Safety and Prevention Act.

The act required the US Occupational Safety and Health Administration to revise regulations governing blood-borne pathogens standards to facilitate the use of “safer medical devices”, including sharp objects with built-in safety mechanisms and needle-less systems.

Under the revised US safety and health regulations, employers must select safer needle devices as they become available and involve employees in identifying and choosing such devices. The updated regulations also require employers to maintain a log of injuries from contaminated sharps.

Just how the EU responds to the risk of infection from needles will unfold over the next few months as the European Parliament begins a debate on sharps and the re-use of disposable medical devices.

So far, EU regulatory officials in Brussels contend that no new law is necessary. Rather, more publicity and better enforcement of existing health and safety laws are what is needed, according to Francisco Jesus Alvarez Hidalgo PhD, who oversees health and safety issues in the European Commission’s directorate of Employment and Social Affairs.

“There is a general idea or feeling that existing legislation is enough,” Dr Hidalgo told a March meeting on sharps, sponsored by the European Parliament.
“Maybe it can be modified maybe it can be improved. But in general terms it is enough. This is a good piece of legislation and if we manage to implement it, it would be a very important step forward.”

Regardless of whether Europe proceeds with new laws or just guidelines, any attempt to reduce injuries from sharps must be practical, warns Ms Minerva Malliori, a Greek member of the European Parliament who is charged with drawing up a parliamentary report on the sharps issue.
“I think that the most difficult part of our discussion has to do not only with the directives, the legislation and the guidelines, but with their implementation,” Ms Mallori told the March Parliament meeting.

“Do the member states have the facilities or the funding to react, to implement or to monitor what we decide? Usually, we are very quick with legislation and we don’t care about the implementation. This is something that we must keep in mind.”

EU law ignores specific risk of needle-stick injuries
Although a number of EU laws generally oblige hospitals and physicians to identify risks and do whatever they reasonably can to eliminate or reduce such risks, no specific law addresses the use and disposal of needles and other sharps.

The existing body of EU law includes:

EU Council Directive 391 of 1989
This directive requires that, if risks cannot be totally eliminated, they must be combated at source. Dangerous practices must be replaced by the non-dangerous or the less-dangerous. Employers are also responsible for adapting their operations to technical progress by using newer technology, which can reduce or eliminate risk.

EU Council Directive 665 of 1989
This directive obliges employers to provide a safe working environment. In this context medical devices are ‘work equipment’ and they must be chosen with a view to avoiding or minimising risk.

EU Council Directive 54 of 2000
Under this directive, employers must assess risk and prevent workers’ exposure to biological risks. If prevention is not technically practicable, the directive obliges employers to reduce the risk to the lowest risk level for adequate protection by means of work place design, engineering control measures, hygiene measures and safe handling of waste. In addition, the directive requires employers to make available their risk assessment information to the appropriate authorities in the individual EU country.

Medical Devices Directive 42 of 1993

Under the Medical Devices Directive, manufacturers must undertake a risk analysis of all medical devices before they place such devices on the market. In doing so, manufacturers should take account of the European Standard for risk assessment, known as “EN 1441” and the European Standard for risk management, known as “EN ISO 14971”. The Medical Devices Directive also requires manufacturers to monitor their devices once they are approved for use. Such monitoring should include following up on reports of adverse events about their devices and taking reasonable measures to manage any risks that users of the devices highlight.
