    Injection safety or safe injection practices are measures taken to protect patients, healthcare providers and others.

    Injection safety includes practices intended to prevent transmission of infectious diseases between one patient and another, or between a patient and healthcare provider and also to prevent needle stick injuries.

    BURDEN OF DISEASE ASSOCIATED WITH UNSAFE INJECTION PRACTICES

    About 16 billion preventive and curative injections are given each year in developing and transitional countries. Over 95% of all injections given are curative (therapeutic): for every vaccination given, 20 therapeutic injections are administered. Because injections are so common, unsafe injection practices are a powerful engine to transmit blood borne pathogens, including hepatitis B (HBV), hepatitis C (HCV) and human immunodeficiency virus (HIV).

    • Hepatitis B: HBV is highly infectious and causes the highest number of infections–in developing and transitional countries 21.7 million people become infected each year, representing 33% of new HBV infections worldwide.

    • Hepatitis C: Unsafe injections are the most common cause of HCV infection in developing and transitional countries, causing two million new infections each year and accounting for 42% of cases.

    • Human immunodeficiency virus: Globally nearly 2% of all new HIV infections are caused by unsafe injections. In South Asia up to 9% of new cases may be caused in this way.

    Because infection with these viruses initially presents no symptoms, it is a silent epidemic. However, these kinds of infection transmissions can be easily controlled.

    HBV, HCV, and HIV cause chronic infections that lead to disease, disability and death a number of years after the unsafe injection. Those infected with hepatitis B in childhood will typically suffer from chronic liver disease by the age of 30.

    3.1 Annual Cost of Unsafe Injections to Healthcare Systems

    A recent study indicated that each year unsafe injections cause an estimated 1.3 million early deaths (a loss of 26 million years of life) and an annual burden of  $535 million in direct medical costs. In 2008, unsafe medical injections incurred $119 billion in productivity losses and costs associated with treating nosocomial HIV, HBV, HCV, bacteraemia and injection site abscesses worldwide.

    In the US, where HBV and HCV infection are not common, the overall cost of HBV and HCV is estimated at $1.3 billion.

    Today the average price of a needle and syringe with reuse prevention features is $0.12. 48 different syringes with reuse prevention features meet WHO specifications for therapeutic injections.

    During the annual review, hospitals should carefully examine safety syringe products currently being used and evaluate all new options that exist. There are three main safety syringe technologies now available to hospitals to help prevent needlestick injuries:

    • Retro-fitted: A conventional syringe with an add-on piece, such as a cap, sheath or shield that covers the needle.

    • Manually retractable: Operating with a simple “Push, Pull, Snap” mechanism to manually withdraw the needle into the syringe barrel and snap off the plunger.

    • Automatically retractable: A spring-activated safety syringe that automatically draws the needle back into the syringe barrel after use.

    Each of these safety syringe designs has pros and cons and it is important for the hospital to consider all aspects of each design. In fact, it is better to compare and contrast examples of the three technologies rather than to compare different products from one technology. Adopting this approach will ensure a better appreciation of what the market has to offer.

    Hospitals may be most familiar with retro-fitted designs, as this was the first type of safety syringe widely introduced for prevention of needlestick injuries. Retro-fitted designs incorporate a safety mechanism–usually attached to the needle and not to the syringe itself–which can be used to cap the needle. Retro-fitted syringes can impede certain procedures, to the point where a clinician may remove the safety mechanism completely in order to proceed, negating the usefulness of the device entirely. In addition, when using the safety mechanism to disable the needle, the clinician’s fingers may still come into close proximity with the needle, raising the possibility of a needlestick injury. And since the safety mechanism may be able to be removed after being engaged, it is possible for the syringe to be reused.

    Automatically retractable designs may be appealing, as the user does not have to do anything upon completion of the injection to avoid needlestick injuries. Working like a ballpoint pen, the needle automatically retracts into the barrel of the syringe. However, such devices may fail if used incorrectly, and there may be aerosolization if retraction is activated outside of the patient. In addition, automatically retractable safety syringes are often significantly more expensive than other options.

    Manually retractable syringes have the look and feel of conventional syringes. The safety mechanism is integral to the syringe and functions with a simple Push, Pull, Snap. After pushing to complete the injection, the plunger is pulled back, retracting the needle into the syringe barrel. Snapping the plunger completes the process, permanently disabling the syringe to prevent any possible re-use. Because the user has control of the mechanism at all times, there is a lowered risk of aerosolization. The user’s hand always remains out of the way of the needle, making it easier to administer injections and reducing the risk of disposal needlestick injuries even further. In addition, manually retractable syringes tend to be more cost-effective than automatically retractable syringes, which can be important when it comes to your facility’s budget.

    When researching new or updated safety syringe options to prevent needlestick injuries, a healthcare facility should also consider the following:

    • Easy-to-read gradation markings

    • Availability of syringes with low dead space

    • Range of syringe sizes

    • Low dose options, particularly for syringes used for insulin

    • Cost

    • Syringes easily labeled at the time of use, ideally with a write-on field

    Summary of the Needlestick Law 
    [Public Law 106-430, 106th Congress, H.R. 5178]

    This landmark achievement for nurses nationwide changed the Blood borne Pathogens standard under the Occupational Health and Safety Act to provide increased protections to workers from exposure to human immunodeficiency virus (HIV), hepatitis B virus and hepatitis C virus, and other viruses and infections. The same year, the Centers for Disease Control and Prevention (CDC) estimated that from 62 percent to 88 percent of sharps injuries potentially could be prevented through use of safer medical devices.

    The law requires employers to use work practice controls and safer needle devices that are engineered to eliminate or minimize exposure to bloodborne pathogens resulting from needlestick injuries. Employers must:

    • Demonstrate that they are reviewing new technology that can reduce risk of exposure to blood borne pathogens by updating exposure control plans and documenting the decision-making process on implementing such technology.

    • Maintain a sharps injury log to track the type and brand of device used, the department or area where the incident occurred, and an explanation of the incident. The log must be maintained in a manner to protect the confidentiality of the injured employee.

    • Solicit input from employees responsible for direct patient care in the identification, evaluation and selection of effective safety devices and work practice controls, as part of the ongoing exposure control plan development process. Efforts to encourage staff input must be documented in the plan.

    Canada: Safe Needles Laws Expand

    The Service Employees International Union (SEIU) Canada is applauding a commitment from the provincial government in Manitoba to convert from conventional to safety-engineered medical sharps devices. ‘Legislation is absolutely vital to protect the workers and people of Manitoba from these potentially deadly injuries,’ said Sharleen Stewart, Canadian international vice-president with SEIU. ‘We must have mandatory use of safety-engineered devices in every workplace – anything less will give us less.’ Ted Mansell, SEIU Canada’s health and safety coordinator, points to the legislation in the US, as well as an announcement made by the neighbouring province of Saskatchewan last month, as a model (Risks 182). ‘Both of those jurisdictions have realised that in order to avoid a patchwork of protection, the conversion must be done across the board,’ he said. ‘If not, we will have some workers protected, others not protected and the on-going threat of used needles in public spaces.’
