Purpose: The objective of this study was to determine the cause-effect and dynamic change mechanism among factors that affect calculation of the nursing workforce in the hemodialysis room and to establish a system dynamics model and create a strategic simulation to be used to increase efficiency in the clinical situation.
Method: The system dynamics approach was adapted to build a simulation model for calculating the nursing workforce. The model was built using Vensim 5.0b DSS.
Results: The results were as follows for Scenario A: The highest level of nursing service quality, patient satisfaction, and nurse satisfaction, and the lowest level of turnover intention is maintained when the ratio of patients to nurse is 3.5:1 compared to all other situations. Scenario B: At the ratio of patients to nurse 4.0:1 nursing service quality, patient satisfaction, and nurse satisfaction dropped slightly, and turnover intention also rose slightly. However with time the results showed improvement.
Conclusion: In terms of economic efficiency in the hemodialysis room, the ratio of patients to nurse for the best nursing workforce should not exceed 4.0:1.
