Practice and application of learning curve theory in improving prescription review skills in standardized training for pharmacists in medical institutions

To explore the practice and application of learning curve theory in improving prescription review skills in standardized training for pharmacists in medical institutions, and to provide reference for enhancing the effectiveness of standardized training for pharmacists in medical institutions. A retrospective analysis was conducted on the relevant data of 20 students who participated in our hospital's standardized pharmacist training in 2022 and 2023 during their prescription review practice learning process. The prescription review practice learning process is divided into 10 stages, with 100 prescriptions in each stage. Three indicators, namely the time spent on the review operation (A1), the accuracy of the review result judgment (A2), and the proficiency of the review system operation (A3), are quantified. The cumulative sum control chart method of binary variables (CUSUM) is used to establish the benchmark target value of the evaluation indicators and the success rate standard of the evaluation indicators. Through accumulation and analysis, the scatter plot was fitted with curves. The stages where the slope of the learning curve began to decrease for different indicators are stage 7, stage 6, and stage 5, respectively. The overall learning curve reaches its peak crossing point in the sixth stage, and prescription review learning transitions from the improvement stage to the proficiency stage. The slope of the individual learning curve began to decrease from stages 4-8. Through further analysis of the correlation between students crossing the learning curve and possible influencing factors, Spearman analysis results shown that students' theoretical exam scores are highly negatively correlated with the number of times they cross the learning curve in practice. By applying the learning curve theory, we can scientifically define the developmental stages of pharmacists' auditing abilities. As the number of prescription reviews accumulates, the prescription review ability and proficiency of the trainees gradually improve, and the accuracy of prescription review significantly increases. The time spent on prescription review is significantly shortened compared to the learning stage, and the system operation proficiency meets the standard. Through the practice and application of learning curve theory, regulatory training institutions provide scientific basis for teaching and training, which can serve as an evaluation standard for the standardized training effect of pharmacist prescription review, and also provide valuable reference for the scientific design of teaching practice for future students.
