Background: Colorectal cancer is among the most prevalent malignancies, and increasing complexity in treatment and care delivery has heightened demand for long-term care (LTC) services. This study aimed to investigate LTC needs among colorectal cancer patients and analyze the influencing predisposing, enabling, and need-related factors based on Andersen’s Behavioral Model of Health Services Use. Materials and methods: A cross-sectional survey was conducted from January 4 to June 8, 2024, at a regional hospital in New Taipei City, Taiwan. A total of 90 patients were enrolled, and data were collected using validated demographic and LTC needs questionnaires. Statistical analyses were performed using SPSS 29.0. Results: The average age of patients was 63.63, with 58.9% male and 92.2% fully independent in daily living functions. The most clearly recognized LTC need was “family caregiver support,” while institutional care had the highest perceived need and willingness to use. Key predictors included age, employment status, living arrangement, economic condition, primary caregiver status, number of LTC information sources, use of as-sistive devices, disability level, specific care (e.g., port-A catheter care), and the number of LTC considerations. Conclusion: Patients exhibited moderate clarity and perceived need for LTC services but showed low willingness to use them. Family caregiver support and institutional care were notably preferred and influenced by multiple Andersen Model factors. These findings offer valuable implications for fu-ture LTC policy development and resource optimization, helping to bridge the gap between care awareness and actual utilization.
