Avoiding Retained Surgical Items at an Academic Medical Center: Sustainability of a Surgical Quality Improvement Project

Unintentionally retained surgical items (RSIs) are a serious complication representing a surgical "Never" event. The authors previously reported the process and significant improvement over a 3-year multiphased quality improvement RSI reduction effort that included sponge-counting technology. Herein, they report the sustainability of that effort over the decade following the formal quality improvement project conclusion. This retrospective analysis includes descriptive and qualitative data collected during RSI event root cause analysis. Between January 2009 and December 2019, 640 889 operations were performed with 24 RSIs reported. The resulting RSI rate of 1 per 26 704 operations represent a 486% performance improvement compared to the preintervention rate of 1 per 5500 operations. The interval, in days, between RSI events increased to 160 from 26 during the preintervention phase. Cotton sponges were the most retained RSI despite the use of sponge-counting technology. A significant and sustained reduction in RSI is possible after designing a sustainable comprehensive multidisciplinary effort.

Using a data-matrix-coded sponge counting system across a surgical practice: impact after 18 months

BACKGROUND

Retained surgical items (RSIs), most commonly sponges, are infrequent. Yet despite sponge-counting standards, failure to maintain an accurate count is a common error. To improve counting performance, technology solutions have been developed. A data-matrix-coded sponge (DMS) system was evaluated and implemented in a high-volume academic surgical practice at Mayo Clinic Rochester (MCR). The primary end point was prevention of sponge RSIs after 18 months.

METHODS

Two trials were conducted before implementation. A randomized-controlled trial assessed the system's function, efficiency, and ergonomics. The second, larger trial was conducted to validate the prior findings and test product improvements. After the trials, the system was implemented in all 128 operating/procedure rooms across the MCR campus on February 2, 2009. The institutionwide implementation was intended to avoid the possibility of having standard unmarked sponges and DMSs in the operating room suite concurrently.

RESULTS

Before implementation, a retained sponge occurred on average every 64 days. Between February 2009 and July 2010, 87,404 procedures were performed, and 1,862,373 DMSs were used without an RSI (p < .001). After four cases, the average time to count a DMS decreased from 11 to 4 seconds. Total sponge counting time/operation increased without any increase in overall operative time.

CONCLUSIONS

After 18 months, a DMS system eliminated sponge RSIs from a high-volume surgical practice. The DMS system caused no work-flow disruption or increases in case duration. Staff satisfaction was acceptable, with a high degree of trust in the system. The DMS system is a reliable and cost-effective technology that improves patient safety.
