In recent years, with the exacerbation of societal aging, private eldercare institutions have assumed increasingly pivotal roles within our nation's eldercare service framework. Nevertheless, beneath the veneer of rapid development, the current state of service quality presents a less than satisfactory scenario. Within the realm of private eldercare institutions, numerous factors collectively influence the caliber of service. Foremost among these concerns is the issue of singular service offerings coupled with inconsistent quality. Many establishments lack rich and comprehensive service provisions in daily care, rehabilitative assistance, and psychological support, resulting in significant disparities in service standards. Moreover, inadequacies in staffing and professional capabilities serve as critical impediments to enhancing service quality. Numerous private eldercare institutions suffer from shortages in both the number and expertise of caregiving personnel, not only hampering the effective execution of daily services but also diminishing the satisfaction levels of service recipients to a certain extent. Furthermore, the issues of management systems and operational efficiency demand equal attention. Many institutions lack innovative and efficient mechanisms in management systems and operational models, leading to irrational resource allocations, inefficient service processes, thereby compromising overall service quality. Against the backdrop of these aforementioned challenges, the comprehensive enhancement of service quality in private eldercare institutions emerges as an urgent issue in need of resolution.
