Circumstances of Percutaneous Sharps Injuries in German Healthcare Workers—An Analysis of the Ten-Year Period from 2015 to 2024 Based on Accident Insurance Data

Despite the implementation of safety-engineered devices (SEDs) in Germany, percutaneous sharps injuries (PSIs) caused by medical devices remain a major occupational risk for healthcare workers. The aim of this study was to analyze the frequency of PSIs and the circumstances of SED-associated PSIs in hospitals, medical practices, and nursing homes. Routine data from a statutory accident insurance provider for 2015–2024 were used to analyze PSI trends (n = 481,575), and survey data from online questionnaires were used to analyze circumstances of PSIs (n = 791). Routine data showed a slight decline (6.1%) in PSIs over the past 10 years across all sectors. Hospitals and medical practices had the highest rates (30.2 and 21.6 PSIs per 1000 full-time equivalents, respectively). The devices most frequently involved were blood collection needles in hospitals and medical practices and insulin pens in nursing homes. Overall, 43.1% of PSIs were related to the improper disposal of used devices. Around 31.1% of PSIs were associated with SEDs. Around 33% of SED-related injuries occurred during disposal. High workload and distraction were the most frequently reported causes of injuries. Regular training should be provided to raise staff awareness of the proper handling and disposal of used devices.
