Fuzzy Logic Application In Determining The Satisfaction Of Inpatients (case Studies Of Herna Medan General Hospital)
Introduction
Building a positive relationship with patients is the key to the success of a hospital. In achieving this, an accurate evaluation model is needed to measure the level of patient satisfaction. This study, which was conducted at Herna Medan Hospital, proposed an innovative evaluation model by utilizing fuzzy logic to measure the satisfaction of inpatients. Fuzzy logic, a mathematical approach that deals with uncertainty and imprecision, has been increasingly used in various fields, including healthcare, to provide more accurate and comprehensive solutions.
Traditional Models and Their Limitations
Traditional models often use a strict set (crisp) with a fixed value range to determine satisfaction. This model has a weakness because it produces limited output, so it is unable to capture the nuances of complexity in patient experience. For instance, a patient may rate a service as "good" or "bad," but this rating may not accurately reflect their true experience. Fuzzy logic, with flexible membership functions such as triangular and sigmoid curves, provides a more accurate solution. This membership function allows the model to provide more detailed results, according to the perception of patients with varying degrees of satisfaction.
The Fuzzy Logic Model
In this study, the instrument in the form of a questionnaire was given to inpatients at Herna RSU Medan. This questionnaire measures various aspects of service, ranging from the quality of medical services to the convenience of facilities. The data obtained was then analyzed using fuzzy logic to determine the level of patient satisfaction with each service unit. The fuzzy logic model used in this study was based on the following steps:
- Data Collection: The questionnaire was administered to inpatients at Herna Medan Hospital.
- Data Analysis: The data was analyzed using fuzzy logic to determine the level of patient satisfaction with each service unit.
- Membership Function: The membership function was used to determine the degree of membership of each patient in each service unit.
- Fuzzy Inference: The fuzzy inference system was used to determine the level of patient satisfaction with each service unit.
Results and Discussion
The results showed that the fuzzy logic model was able to produce a more comprehensive assessment than the traditional model. The use of a triangular and sigmoid curve, even though it produces the same linguistic, provides a different degree of membership. This proves that this model is able to capture subtle differences in the patient's perception and provide a more accurate assessment. The results also showed that the fuzzy logic model was able to identify the best and unsatisfactory service units, which is a valuable information for management to determine the development strategy and improve the quality of service.
Benefits of the Fuzzy Logic-Based Evaluation Model
This fuzzy logic-based evaluation model has several benefits for Herna Medan Hospital:
Identification of the Best and Unsatisfactory Service Units
This model can be used to identify service units that provide the best services and units that need to be improved. This information is very valuable for management to determine the development strategy and improve the quality of service.
A Deeper Understanding of Patient Satisfaction
This model provides a deeper understanding of patient satisfaction, because it considers the nuances and complexity of the patient's experience.
Improving Service Quality
By understanding the factors that affect patient satisfaction, Herna Medan Hospital can focus on improving service quality and creating better patient experiences.
The Importance of Standardization in Assessment
Although this model provides a more comprehensive solution, keep in mind that standard assessment standards remain important in measuring patient satisfaction. This standardization will help ensure that the assessment carried out in various hospitals can be compared and interpreted consistently.
Conclusion
Fuzzy logic-based evaluation model can be an effective tool for hospitals to increase patient satisfaction and build closer relationships with them. Its advantage in capturing the nuances of complexity in patient experience makes this model a more appropriate solution in measuring the satisfaction of inpatients. This study demonstrates the potential of fuzzy logic in healthcare and highlights the importance of standardization in assessment.

Q: What is fuzzy logic, and how does it relate to patient satisfaction?
A: Fuzzy logic is a mathematical approach that deals with uncertainty and imprecision. In the context of patient satisfaction, fuzzy logic is used to measure the level of satisfaction with various aspects of healthcare services, such as quality of care, convenience of facilities, and communication with healthcare providers.
Q: What are the benefits of using fuzzy logic in measuring patient satisfaction?
A: The benefits of using fuzzy logic in measuring patient satisfaction include:
- More accurate and comprehensive results: Fuzzy logic can capture subtle differences in patient experience and provide a more accurate assessment of satisfaction.
- Identification of best and unsatisfactory service units: Fuzzy logic can identify service units that provide the best services and units that need to be improved.
- Deeper understanding of patient satisfaction: Fuzzy logic provides a deeper understanding of patient satisfaction, considering the nuances and complexity of the patient's experience.
Q: How does fuzzy logic work in measuring patient satisfaction?
A: Fuzzy logic works by using a membership function to determine the degree of membership of each patient in each service unit. The membership function is used to assign a value to each patient's experience, based on their perception of the service. The fuzzy inference system is then used to determine the level of patient satisfaction with each service unit.
