1,300 Days and Counting: A Risk Model Approach to Preventing Retained Foreign Objects (RFOs).

Background: A retained foreign object (RFO) is a devastating surgical complication that typically results in additional surgeries, increased length of stay, and risk of infections and is potentially fatal. Memorial Sloan Kettering Cancer Center (MSKCC) convened a multidisciplinary task force to undertake an improvement initiative to reduce the frequency of RFO incidents.

Methods: A needs assessment was undertaken using focus group interviews, review of past RFOs, and operating room (OR) observations, and a comprehensive intervention plan was initiated. Items at risk of retention were reclassified and new tracking sheets were developed. A probabilistic risk model was developed based on aviation industry methodology, an RFO risk projection, and the retention risk classification of surgical items. Training initiatives were launched to shift organizational culture and staff behaviors toward greater awareness of RFO risk and proactive prevention.

Results: Since the implementation of our task force's recommendations on March 24, 2014, there have been no RFO incidents at our institution to this day. The last RFO occurred in August 2013-more than 1,300 days ago (as of March 28, 2017). The RFO incident frequency was reduced from 1.69 per year to a risk model estimate of 1 in 22 years. Ongoing training maintains the staff's behavioral changes as well as the improved OR and organizational culture.

Conclusion: Implementation of a multidisciplinary approach to preventing RFOs was successful at MSKCC. The use of an RFO risk model enabled the creation of a robust system for RFO prevention. Support from leadership, participation by all stakeholders, education, training, and cooperation from frontline staff are all important contributors to RFO prevention success.
