International Journal of Clinical Case Reports, 2025, Vol.15, No.2, 68-78 http://medscipublisher.com/index.php/ijccr 73 Jayawardhana (2015) pointed out that loneliness is a major factor affecting the quality of life of elderly individuals, and home care interventions can effectively address this issue, thereby enhancing overall life satisfaction. 5 Factors Affecting the Effectiveness of Community-Based Home Care 5.1 Frequency and duration of care services The frequency and duration of care services are critical factors that influence the effectiveness of community-based home care. High-frequency and long-term care services provide more stable support for elderly individuals living alone, helping them achieve notable improvements in both physical and mental health. Frequent care visits allow caregivers to monitor health conditions more effectively and address sudden health issues promptly, reducing dependence on emergency or hospital care. Research has shown that regular and continuous care services significantly improve the quality of life of elderly individuals; for example, Wang et al. (2022) found that elderly individuals receiving high-frequency care services experience significant improvements in mental health and life satisfaction (Figure 3). Additionally, continuous care services help establish a trusting relationship between elderly individuals and caregivers, and this long-term emotional bond enhances acceptance and dependence on care, improving overall effectiveness (Chen and Hsu, 2020). Figure 3 Propensity scores in treatment and control groups (nuclear matching) (Adopted from Wang et al., 2022) On the other hand, the frequency and duration of care services need to be adjusted based on individual needs. For instance, elderly individuals with chronic illnesses or special care needs may require more frequent and long-term care, whereas those in relatively good health may benefit from a reduced frequency. Imanishi et al. (2015) found a significant correlation between the duration of care and mental health and life satisfaction, with long-term care associated with reduced loneliness and depressive symptoms among elderly individuals. Therefore, adjusting the frequency and duration of care services to meet individual needs can not only improve care quality but also better fulfill personalized needs, enhancing satisfaction with the services. 5.2 Training and skill level of caregivers The training and skill level of caregivers directly impact the quality of community-based home care services. Skilled caregivers with professional knowledge and abilities can more accurately identify the health needs of elderly individuals and provide personalized care, significantly improving care outcomes. Essential caregiver skills include chronic disease management, psychological counseling, and emergency handling, which enable caregivers to make more professional judgments and responses in complex situations. Boland et al. (2017) indicated that highly trained caregivers are better able to assist elderly individuals in managing chronic diseases and addressing mental health issues, reducing anxiety and depression caused by physical discomfort or emotional stress. Su and Wang (2019) also found that highly qualified caregivers perform well in providing psychological support, establishing positive emotional connections in the care process, which contributes to improved mental health among elderly individuals.
