This commentary letter was conducted to evaluate Wang et al.'s (2025) research study on the relationship between perceived staffing and quality of care among hospitals. The current study's findings show that the relationship between professional self-efficacy and job performance is mediated by work engagement. Life contentment influences work engagement, which is associated with enhanced job performance. However, involvement acts as a mediator between job performance and burnout, which could affect the quality of patient care. Staffing satisfaction and quality patient care are closely related, and it is essential for healthcare institutions to prioritize appropriate workforce levels and address the nursing shortage. However, there are still unanswered questions in this sector, such as researching nursing-specific care procedures, addressing data challenges, and understanding the connections between nursing practice and patient care outcomes. Future research should address the "black box" of nursing practice and address variations in the quality of patient care provided by nurses.
