<p>Evaluating Surgical Risk Using FMEA and MULTIMOORA Methods under a Single-Valued Trapezoidal Neutrosophic Environment</p>

Abstract

Background Human errors during operations may seriously threaten patient recovery and safety and affect the doctor–patient relationship. Therefore, risk evaluation of the surgical process is critical. Risk evaluation by failure mode and effect analysis (FMEA) is a prospective technology that can identify and evaluate potential failure modes in the surgical process to ensure surgical quality and patient safety. In this study, a hybrid surgical risk–evaluation model was proposed using FMEA and multiobjective optimization on the basis of ratio analysis plus full multiplicative form (MULTIMOORA) method under a single-valued trapezoidal neutrosophic environment. This work aimed to determine the most critical risk points during the surgical process and analyze corresponding solutions. Methods A team for FMEA was established from domain experts from different departments in a hospital in Hunan Province. Single-valued trapezoidal neutrosophic numbers (SVTNNs) were used to evaluate potential risk factors in the surgical process. Cmprehensive weights combining subjective and objective weights were determined by the best–worst method and entropy method to differentiate the importance of risk factors. The SVTNN–MULTIMOORA method was utilized to calculate the risk-priority order of failure modes in a surgical process. Results The hybrid FMEA model under the SVTNN–MULTIMOORA method was used to calculate the ranking of severity of 21 failure modes in the surgical process. An unclear diagnosis is the most critical failure in the surgical process of a hospital in Hunan Province. Conclusion The proposed model can identify and evaluate the most critical potential failure modes of the surgical process effectively. In addition, such a model can help hospitals to reduce surgical risk and improve the safety of surgery.

Utilization of Nursing Defect Management Evaluation and Deep Learning in Nursing Process Reengineering Optimization

“…The patient comes first, which needs to improve service quality, control service cost according to patients' needs, and formulate more convenient measures according to more simplified workflow to provide patients with "high quality, high efficiency, satisfaction, low consumption, and reassurance" medical services [4]. The process of nursing process reengineering takes nurses and patients as the center of the whole nursing work and comprehensively changes some management concepts, working methods, and customary practices in the previous nursing process, so as to adapt to the competition in the modern medical market and people's higher requirements for the level of health services [5,6]. Process reengineering refers to the process of completing an activity, a task, and an event.…”

Using Failure Mode and Effect Analysis to Identify Potential Failures in a Psychiatric Hospital Emergency Department

“…18 Failure mode and effect analysis is often criticized for a lack of precision because it only includes a small group of analysts, relies on average scores, and is sensitive to minor variations in the scoring scale, which may lead to changes in the RPN grade, depending on the rankings of the team members. 17,21,22 This study tripled the number of study participants in the FMEA analysis compared with other studies that included only 12. This allowed us to use statistical tools other than simple means, which was considered a weakness in FMEA.…”

Risk Evaluation of Water Environmental Treatment PPP Projects Based on the Intuitionistic Fuzzy MULTIMOORA Improved FMEA Method

“…The traditional FMEA risk assessment process does not take into account risk factor weighting information and treats O, S and D as equally important, which is clearly not the case and results in a less accurate risk sequence for the final failure mode. However, it is difficult to determine the risk factor weights directly, so many weight calculation methods have been applied to determine the risk factor weights in FMEA, mainly the subjective weighting method [26], the objective weighting method [56] and the comprehensive weighting method [57], among which the comprehensive assignment method has been adopted by many scholars because it can consider both subjective and objective reasons.…”
