  • Background: Sharp exposures are a major risk for healthcare workers.  Acute care hospitals are mandated to review all reported injuries and institute preventative measures.  Routine surveillance suggested an increasing frequency of needlestick injuries in healthcare workers injecting local anesthesia; therefore, a comprehensive review was performed. 

    Methods: All needlestick injuries at UMass Memorial Medical Center, an academic medical center, for the years 2004 through 2013 were collected, and rates of injuries per 1000 employees were calculated.  Descriptive statistics, test of trend, and U statistical process control charts were used to describe the sharps injury incidence rate over time.

    The rate and number of both total sharps injuries and non-insulin and non-local anesthesia associated hollow bore needlestick injuries per year showed statistically significant decreasing trends for the period 2004 to 2013 (p<0.0033; p<0.0002).  In contrast, the incidence of local anesthesia associated injuries demonstrated a statistically significant increasing trend over time (p<0.0167)(fig. below).  There were no significant changes in the rates of other sharps injuries.

    Conclusion: Over a 10 year period the rate of local anesthesia associated needle stick injuries increased at our institution as the overall rate of sharps injuries decreased.  This trend may be related to persistent unsafe practices, as practitioners frequently perform repeat injections with the same needle when administering local anesthesia.  Further investigation of this issue is warranted.
