The risk transmission of blood-borne viruses has been shown to be around 1 in 3 if the patient is Hepatitis B Virus positive, 1 in 30 if Hepatitis C Virus positive and 1 in 300 if HIV positive [2, 3]. Even when infections are not transmitted such an injury can cause considerable fear and stress [4].<\/p>\n<p>In many cases, it is not feasible to eliminate injections or use another administration method as a substitute.\u00a0 Therefore, the hazard is most effectively handled by engineering solutions which separate those at risk from the sharps (Figure 1). Research by the UK\u2019s Health and Safety Executive has found that education and training related to safer sharps is only effective when combined with safer sharps devices [5] and the UK\u2019s Health Protection Agency recommends that Primary Care Trusts and hospitals adopt safety devices in place of conventional devices [2].\u00a0 In the US, the CDC estimated that up to 88% of sharps injuries in hospitals could be prevented by using safer medical devices [6].<\/p>\n<p><a class=\"is-inset-wrap\" href=\"https:\/\/www.sanner-group.com\/wp-content\/uploads\/2018\/06\/Figure-1.avif\"><img loading=\"lazy\" decoding=\"async\" class=\"full-width-image\" src=\"https:\/\/www.sanner-group.com\/wp-content\/uploads\/2018\/06\/Figure-1.avif\" sizes=\"auto, (max-width: 575px) 100vw, 575px\" srcset=\"https:\/\/www.sanner-group.com\/wp-content\/uploads\/2018\/06\/Figure-1.avif 575w, https:\/\/www.sanner-group.com\/wp-content\/uploads\/2018\/06\/Figure-1-300x201.avif 300w\" alt=\"\" width=\"575\" height=\"385\" \/><\/a><\/p>\n<p style=\"text-align: center;\">Figure 1 &#8211; Hierarchy of hazard controls with increasing effectiveness\u00a0(Source: <a href=\"https:\/\/www.cdc.gov\/niosh\/topics\/hierarchy\/default.html\">National Institute for Occupational Safety and Health<\/a>)<\/p>\n<h2>The legal requirements<\/h2>\n<p>Many regulators around the world require needlestick protection, and others are in the process of implementing it.\u00a0 Examples are:<\/p>\n<ul>\n<li><a href=\"https:\/\/www.osha.gov\/needlesticks\/needlefaq.html\">US Needlestick Safety and Prevention Act<\/a> (2000)<\/li>\n<li><a href=\"https:\/\/osha.europa.eu\/en\/legislation\/directives\/council-directive-2010-32-eu-prevention-from-sharp-injuries-in-the-hospital-and-healthcare-sector\">EU Directive 2010\/32\/EU<\/a> \u2013 prevention from sharp injuries in the hospital and healthcare sector<\/li>\n<\/ul>\n<p>The international standard <a href=\"https:\/\/www.iso.org\/standard\/50680.html\">ISO 23908:2011<\/a> defines the requirements and test methods for sharps protection features on single-use hypodermic needles, introducers for catheters, and needles used for blood sampling.<\/p>\n<h2>&#8222;Active&#8220; and &#8222;passive&#8220; solutions<\/h2>\n<p>Broadly, solutions can be classed as:<\/p>\n<ul>\n<li>Active (the user must take some type of action to initiate the feature) or<\/li>\n<li>Passive (the feature is activated automatically, without user intervention).<\/li>\n<\/ul>\n<p>Active solutions rely on the HCW completing an extra step, which relies on training and changing existing behaviors. The UK National Health Service Employers organization recommends that needle safety mechanisms should be an integral part of the device, require little change of technique and are preferably activated automatically or with a single hand [7].<\/p>\n<p>A simple active solution is to cap the exposed needle with a shield after use, such as Smith Medical\u2019s Point-Lok\u00ae needle protection device (Figure 2).\u00a0 The device sits on a flat surface to accept and lock onto the exposed needle.<\/p>\n<p><a class=\"is-inset-wrap\" href=\"https:\/\/www.sanner-group.com\/wp-content\/uploads\/2018\/06\/Figure-2.avif\"><img loading=\"lazy\" decoding=\"async\" class=\"full-width-image\" src=\"https:\/\/www.sanner-group.com\/wp-content\/uploads\/2018\/06\/Figure-2.avif\" sizes=\"auto, (max-width: 391px) 100vw, 391px\" srcset=\"https:\/\/www.sanner-group.com\/wp-content\/uploads\/2018\/06\/Figure-2.avif 391w, https:\/\/www.sanner-group.com\/wp-content\/uploads\/2018\/06\/Figure-2-300x278.avif 300w\" alt=\"\" width=\"391\" height=\"362\" \/><\/a><\/p>\n<p style=\"text-align: center;\">Figure 2 \u2013 Smith Medical\u2019s Point-Lok\u00ae needle protection device<\/p>\n<h2>Active Sharps Injury Protection (sheath)<\/h2>\n<p>Syringes with integral sharps injury protection (SIP) often use a cover that shields the user from the needle after use.\u00a0 This cover can be an extendable tube (Figure 3).

The sheath covers the outer surface of the barrel during the injection.\u00a0 These syringes should be held by the flange, so the sheath is not displaced before the end of the injection.
