![]() Proper identification of patients and blood sample tests are the keys to a significant decrease in blood sampling errors. A critical focus should be conducted on the preparation phase due to the possible errors that may occur. Many factors lead to blood sampling errors. This resulted in a 58 % reduction in the RPN of major failure modes. These themes included: process and responsibility modifications, resource and information technology utilization, patients and family engagement, safety culture, and education and training after implementation of the corrective actions. Accordingly, five themes were developed to guide the corrective actions. Seven steps were conducted, including a review of the blood sampling process, brainstorming potential failures, listing potential effects of each failure mode, assigning a severity rating for each potential effect, assigning a frequency/occurrence rating for each failure mode, assigning a detection rating scale for each failure mode, and calculating the Risk Priority Number (RPN) for each effect.Įight (out of 28) main critical failure modes with more than 200 RPN were identified in the blood sampling process. This project aimed to assess and improve the nursing blood sampling process in a specialized cancer center using failure mode and effect analysis (FMEA).Īn observational analytical design of the nursing blood sampling process using FMEA was conducted in King Hussein Cancer Center in Amman, Jordan. Any failure at any point could have a severe negative impact on patient outcomes. This presentation will compare and contrast the traditional RPN and the action priority (AP) table methods for FMEA as well as provide practical examples of the application of the action priority (AP) table method.The process of blood sampling is considered one of the primary and most common nursing invasive procedures carried out daily. The priorities are derived from weighted hierarchical rankings considering Severity, Occurrence, and Detection. The AP tables assign one of three suggested rankings (High, Medium, and Low Priority) for each action based upon the Severity, Occurrence, and Detection values. The RPN has been replaced by the action priority (AP) table. One of the major changes with the new AIAG-VDA FMEA process is the traditional RPN has been eliminated. The Automotive Industry Action Group (AIAG) and the Verband der Automobilindustrie (VDA) jointly released an updated FMEA handbook on April 2, 2019. The RPN output of an FMEA is a relative risk score for each failure mode, which is used to rank the failure modes of relative risk to allow the organization to prioritize risk mitigation and reduction activities. Detection (D) is the probability that control (design, inspection, alert/warning) will eliminate, mitigate, or catch the defect. A novel method to risk evaluation based on D numbers theory based on the combination usage of risk priority number (RPN) and the risk coefficient newly. Probability of occurrence (O) is the likelihood that a harm or cause will occur and that it will induce the detrimental consequences of the associated hazard. Severity (S) is a measure of the seriousness of the possible consequences of a hazard. ![]() Mark Allen Durivage, Managing Principal Consultant, Quality Systems Compliance LLC, Lambertville, MI, USAįailure mode effect analysis (FMEA) risk priority number (RPN) scores have traditionally been used to quantify risks for use, design, and process FMEAs.įMEA helps quantify and prioritize risk using severity of the harm, probability of occurrence, and probability of detection ratings that are multiplied together to produce the RPN.
