Abstract ▼ AI-Helper

Patient safety has become a growing concern in health care. The U.S. Institute of Medicine (IOM) report "To Err Is Human: Building a Safer Health System" in 1999 included estimations that medical error is the eighth leading cause of death in the United States and results in up to 100,000 deaths annually. However, many adverse events and errors occur in surgical practice. Within all kinds of surgical adverse events, wrong-side/wrong-site, wrong-procedure, and wrong-patient adverse events are the most devastating, unacceptable, and often result in litigation. Much literature claims that systems must be put in place to render it essentially impossible or at least extremely difficult for human error to cause harm to patients. Hence, this research aims to develop a prototype system based on active RFID that detects and prevents errors in the OR. To fully comprehend the operating room (OR) process, multiple rounds of on site discussions were conducted. IDEF0 models were subsequently constructed for identifying the opportunity of improvement and performing before-after analysis. Based on the analysis, the architecture of the proposed RFID-based OR system was developed. An on-site survey conducted subsequently for better understanding the hardware requirement will then be illustrated. Finally, an RFID-enhanced system based on both the proposed architecture and test results was developed for gaining better control and improving the safety level of the surgical operations.

문제 정의

Whether wrong patient, wrong location, wrong medical staff or wrong operation event has resulted in injury or didn’t raise actual harm, those kind of events cause anxiety for patients and staff, disrupt the smooth flow of patients through the OR suite, and increase the probability of medical errors. Hence, this research aims to develop a prototype system based on RFID that detects and prevents errors in the OR. The system provides hospitals to correctly identify surgical patients and track their operations to ensure they get the correct operations at the right time.

제안 방법

After a series of admission procedure, the nurse logged on to the hospital information system to change the patient’s status.
Patient safety is the most important and uncompromised issue for medical institutions. In this research, we analyzed the existing OR process based on the as-is model and developed the RFID-based OR process. This RFID-based process can improve surgical patient safety and make medical staff efficient.
With sufficient information regarding the as-is operation, analyzing current process and building a new system become easier. Second, we examined the model, found out the operations which probably threaten to patient safety or make medical staff ineffective and analyzed the opportunity for introducing RFID to solve the problem.
From the surgical patient safety point of views, the RFID-based OR system (1) correctly identifies surgical patients, (2) automatically compares the OR which patients enter with the OR sche dule, and (3) actively provides patients’ information to ensure that patients get correct procedures. The proposed system decreases the probability of medical errors such as wrong patients, wrong locations, wrong medical staff and wrong procedures. From the medical staff point of views, the system replaces some time-wasted manual input processes.
The purpose of this model is to find out the systemic vulnerabilities that may lead to human error and the opportunities that can improve medical staff’s operations by introducing RFID technology.

성능/효과

2. Entering the wrong OR: In general, a teaching medical center has numbers of contiguous ORs, each performing two to three cases daily. Moreover, OR schedule varies frequently.
5. Inefficiently updating patient’s states: Based on the as-is model, nurses have to manually update a patient’s status information (in surgery, in recovery, etc.) in the hospital information system when the patient’s status is changed.

용어 설명: PCR은 세균 특이성이 있는 primer를 이용하여 적은 수의 세균이 있을지라도 쉽게 검출할 수 있는 유용한 방법이며, 이를 이용하여 구강 내 치면세균막이나 타액에서 직접 세균을 검출할 수 있게 되었다[8].
