Abstract
Objective
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.
Method
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. The cumulative sum of the evaluation indicators of the research object is calculated (∑=A1 + A2 + A3), and a learning curve is drawn. The polynomial curve is fitted, and the fitting function y is differentiated and the derivative is obtained. The derivative value of each stage corresponds to the slope k of each point on the fitting curve. When the value of k changes from positive to negative, it successfully crosses the learning curve.
Results
Through accumulation and analysis, the scatter plot was fitted with a curve to obtain the best fitting model. The fitted curve reached a peak crossing in the sixth stage of prescription review, and the curve changed from rising to falling from this point. The k value of the curve was negative, and the prescription review ability crossed the learning curve. Prescription review learning transitioned from the improvement stage to the proficiency stage.
Conclusion
With the accumulation of prescription review sheets, the prescription review ability and proficiency of the trainees gradually improve. After the sixth stage, they reach proficiency, and the time spent is significantly shortened compared to the learning stage. The accuracy of the review results is significantly improved, and the system operation proficiency meets the standard. By studying the learning curve, regulatory training institutions can provide teachers with a more scientific reference, which can serve as an evaluation standard for the effectiveness of standardized training in pharmacist prescription review.
