Background A retained surgical item (RSI) is defined as a never-event and can have drastic consequences on patient, provider, and hospital. However, despite increased efforts, RSI events remain the number one sentinel event each year. Hard foreign bodies (e.g. surgical sharps) have experienced a relative increase in total RSI events over the past decade. Despite this, there is a lack of literature directed towards this category of RSI event. Here we provide a systematic review that focuses on hard RSIs and their unique challenges, impact, and strategies for prevention and management. Methods Multiple systematic reviews on hard RSI events were performed and reported using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) and AMSTAR (Assessing the methodological quality of systematic reviews) guidelines. Database searches were limited to the last 10 years and included surgical “sharps,” a term encompassing needles, blades, instruments, wires, and fragments. Separate systematic review was performed for each subset of “sharps”. Reviewers applied reciprocal synthesis and refutational synthesis to summarize the evidence and create a qualitative overview. Results Increased vigilance and improved counting are not enough to eliminate hard RSI events. The accurate reporting of all RSI events and near miss events is a critical step in determining ways to prevent RSI events. The implementation of new technologies, such as barcode or RFID labelling, has been shown to improve patient safety, patient outcomes, and to reduce costs associated with retained soft items, while magnetic retrieval devices, sharp detectors and computer-assisted detection systems appear to be promising tools for increasing the success of metallic RSI recovery. Conclusion The entire healthcare system is negatively impacted by a RSI event. A proactive multimodal approach that focuses on improving team communication and institutional support system, standardizing reports and implementing new technologies is the most effective way to improve the management and prevention of RSI events.

Introduction A retained surgical sharp (RSS) is a never event and defined as a lost sharp (needle, blade, instrument, guidewire, metal fragment) that is not recovered prior to the patient leaving the operating room. A “near-miss” sharp (NMS) is an intraoperative event where there is a lost surgical sharp that is recovered prior to the patient leaving the operating room. With underreporting of such incidents, it is unrealistic to expect aggressive development of new prevention and detection strategies. Moreover, awareness about the issue of “near-miss” or retained surgical sharps remains limited. The aim of this large-scale national survey-based study was to estimate the incidence of these events and to identify the challenges surrounding the use of surgical sharps in daily practice. Methods We hypothesized that there was a larger number of RSS and NMS events than what was being reported. We survived the different OR team members to determine if there would be discordance in reported incidence between groups and to also evaluate for user bias. An electronic survey was distributed to OR staff between December 2019 and April 2020. Respondents included those practicing within the United States from both private and academic institutions. Participants were initially obtained by designating three points of contact who identified participants at their respective academic institutions and while attending specialty specific medical conferences. Together, these efforts totaled 197 responses. To increase the number of respondents, additional emails were sent to online member registries. Approximately 2650 emails were sent resulting in an additional 250 responses (9.4% response rate). No follow up reminders were sent. In total, there were 447 survey responses, in which 411 were used for further analysis. Thirty-six responses were removed due to incomplete respondent data. Those who did not meet the definition of one of the three categories of respondents were also excluded. The 411 were then categorized by group to include 94 (22.9%) from anesthesiologist, 132 (32.1%) from resident/fellow/attending surgeon and 185 (45%) from surgical nurse and technologist. Survey The survey was anonymous. Participants were asked to answer three demographic questions as well as eight questions related to their personal perception of NMS and RSS (Fig. 1). Demographic questions were asked with care to ensure no identifiable information was obtained and therefore unable to be traced back to a specific respondent or institution. Perception questions 4–6 and 11 were designed to understand the incidence of various sharp events (e.g. lost, retained, miscounted). Questions 7 and 10 were dedicated to understanding time spent managing sharps and questions 8 and 9 were dedicated to understanding the use x-ray and its effectiveness. Results Overall, most of each respondent group reported 1–5 lost sharp events over the last year. Roughly 20% of surgeons believed they never had a miscounted sharp over the last year, where only 5.3% of anesthesiologist reported the same (p = 0.002). Each group agreed that roughly 4 lost events occur every 1000 surgeries, but a significant difference was found between the three groups regarding the number of lost sharps not recovered per 10,000 surgeries with anesthesiologist, surgeon and nurse/technologist groups estimating 2.37, 2.56 and 2.94 respectively (p = 0.001). All groups noted x-ray to offer poor effectiveness at 26–50% with 31-40 min added for each time x-ray was used. More than half (56.8%) of surgeons reported using x-ray 100% of the time when managing a lost sharp whereas anesthesiologists and nurses/technologists believe it is closer to 1/3 of the time. An average of 21-30 min is spent managing each NMS, making a lost sharp event result in up to 70 min of added OR time. Conclusions “Near-miss” and RSS are more prevalent than what is reported in current literature. Surgeons perceive a higher rate of success in retrieving the RSS when compared to anesthesiologists and OR nurses/technologists. We recognize several challenges surrounding “near-miss” and never events as contributing factors to their underreported nature and the higher degree of surgeon recall bias associated with these events. Additionally, we highlight that current methods for prevention are costly in time and resources without improvement in patient safety. As NMS and RSS have significant health system implications, a strong understanding of these implications is important as we strive to improve patient safety.
