ABSTRACT

Background:

Cardiovascular and cerebrovascular diseases significantly contribute to global mortality and disability. The shift to outpatient postoperative care, accelerated by the COVID-19 pandemic, emphasizes the need for effective management of postoperative outcomes. In Korea, high rates of these diseases necessitate focused transitional care during patient discharge periods.

Objective:

This study analyzed the emotional experiences of patients discharged after cardiovascular and cerebrovascular surgeries using data from Naver, a major South Korean web portal.

Methods:

Posts were collected using specific keywords and processed with the KoBERT model based on Transformer, which classified sentiments into positive, neutral, and negative categories. The model's performance was validated using precision, recall, F1 score, and support metrics. Sentiment analysis was conducted within the Transitional Care Model (TCM) framework, divided into five domains: health status, care resources, care demand, interaction, and mental state.

Results:

The KoBERT model showed high performance with precision, recall, and F1 scores over 0.8. Cerebrovascular surgery patients exhibited higher negative emotions, particularly in health status, compared to cardiovascular surgery patients who had higher negative sentiments in care demands. Keywords within the TCM framework highlighted that cerebrovascular patients emphasized rehabilitation and caregiver support, while cardiovascular patients focused on cost-related concerns.

Conclusions:

The study suggests the need for tailored transitional care for cardiovascular and cerebrovascular diseases. Cerebrovascular patients require robust rehabilitation and caregiver support, while cardiovascular patients need better cost management. These insights can guide policy recommendations to improve patient-centered transitional care, ensuring continuous and effective postoperative management.
