Impact of safety-engineered devices (SEDs) on the prevention of percutaneous injuries

Abstract Background Needlestick injuries represent a major occupational hazard for healthcare workers as they lead to exposure to biological fluids, with higher risk of bloodborne pathogen infections. In order to minimise this risk, safety-engineered devices (SEDs) have been developed and introduced into the daily hospital practice. An annual survey, conducted by the Department of Public Health Sciences of the University of Turin since 1999, has been evaluating the number of percutaneous accidents in the hospitals of Piedmont (Italy), assessing also the impact of the introduction of SEDs on the injury incidence rate. The aim of this study is therefore to evaluate the efficacy of SEDs in preventing needlestick injuries. Methods Data about percutaneous injuries and needle consumption were obtained from 42 hospitals of Piedmont for the years 2014-2017, concerning all the types of needles and sharps most commonly used in the departments. After considering the overall trend of percutaneous events, standardised rates for 100000 needles were computed for both SEDs and conventional devices. The same analysis was performed considering all sharps except standard needles, which are mainly used for procedures not involving contact with patients (e.g. drug dilution). Results The comparison between the incidence rates with SEDs and conventional devices showed a slightly protective effect of SEDs in 2014, 2016 and 2017, with an incidence rate ratio ranging from 0.78 to 0.97. However, by removing the confounding effect of standard needles, the analysis yielded strong statistical evidence of the protective effect of SEDs for all years (RR = 0.28-0.63). Moreover, the total number of percutaneous events shows a trend of general decrease. Conclusions Safety devices have proved to be significantly effective in the prevention of needlestick injuries, and their introduction into the daily practice is one of the factors who could contribute to a reduction of percutaneous events. Key messages Safety-engineered devices are a very important tool in the prevention of injuries in healthcare workers, and their introduction into hospital practice has reduced the number of percutaneous injuries. Safety-engineered devices are significantly protective against percutaneous injuries compared to conventional ones, especially for procedures involving contact with patients (therefore at high risk).
