Effectiveness of a Teaching Model using QR Codes in Patients before Cardiac Surgery
Keywords:
Open heart surgery, Efficacy, QR codeAbstract
This quasi-experimental study aimed to assess the effectiveness of the utilization of QR codes in a teaching model for patients before open-heart surgery, focusing on improving their preoperative knowledge and reducing anxiety. The samples included 70 patients from the Institute of Chest Diseases, divided into the control and the experimental groups, each of which containing 35 participants.
The research tools included a teaching model with QR codes and a data collection form verified by experts in patient education and surgical care. The collected data covered personal information, surgery details, preoperative knowledge, cooperation in preoperative practices, and satisfaction with the QR code-based teaching model. Descriptive statistics and T-tests were used to analyze the data.
The results showed a significant increase in preoperative knowledge for both groups after the intervention (p < .05). No significant difference was observed between the groups prior to the intervention, but in the post-intervention, the experimental group scored significantly higher than the control group (p < .05). Both groups showed high cooperation, and the experimental group reported high satisfaction with the teaching model.
In conclusion, using QR codes effectively increased patients' knowledge and satisfaction. Future research should explore the long-term impact and address potential limitations, such as patient access to technology. The findings can help develop preoperative teaching models using technologies like mobile apps or video tutorials to improve patient preparation.
