[Using Healthcare Failure Mode and Effects Analysis to Reduce Intra-Arterial Thrombectomy Preoperative Preparation Error Rates in the Emergency Room].

BACKGROUND & PROBLEMS: Intra-arterial thrombectomy (IAT) is a novel surgery that may restore cerebral blood flow in patients with ischemic stroke and lower the risks of permanent brain damage and disability. Because the process of preoperative preparation for IAT is complicated, error rates for this process have been reported in previous studies to be as high as 100%. Although these errors did not result in serious damage to patients, the risk to patient safety remains. Therefore, reducing the error rate for IAT preoperative preparation is necessary to improve patient safety.

PURPOSE

To reduce the rate of IAT preoperative preparation error in an emergency room.

RESOLUTION

This project applied healthcare failure mode and effect analysis (HFMEA) to evaluate the potential risks of IAT preoperative preparation in an emergency room. Based on the resultant hazard score, critical preventive measures were adopted, including creating a quick response code consent form, designing order packages, developing a checklist form, modifying stroke operating procedures and policies, planning suitable education content for staffs, developing criteria for evaluating preoperative preparation procedures, and installing vital signs equipment.

RESULTS

After implementation of these measures, the hazard scores of 13 out of the 16 potential failure causes decreased to < 8, and the progress rate was 81.3%. The follow-up error rate for preoperative preparation was 0% in October 2019, which fulfilled the goal of this project.

CONCLUSIONS

Preoperative preparation for IAT is complicated and time-consuming. In this project, HFMEA was introduced to ensure that preoperative preparation was accomplished in a complete and timely manner. Based on the results, after implementation, preparation work was effectively completed and operations were performed on schedule. Other hospitals may consider using this tool to evaluate potential risks to patient safety and to develop solutions to improve the quality of healthcare processes.
