This prospective randomized controlled trial investigated the effects of an evidence-based nursing intervention under a quantitative assessment strategy (EB-NQAS), utilizing the Edmonton Symptom Assessment Scale (ESAS), on cancer-related fatigue, self-management ability, and quality of life in lung cancer patients undergoing chemotherapy. Outcomes were compared to a group receiving routine nursing care.

Lung cancer patients undergoing chemotherapy frequently experience significant cancer-related fatigue (CRF) and diminished quality of life (QoL), which may not be adequately addressed by conventional nursing approaches. This study aimed to evaluate the efficacy of an evidence-based nursing intervention guided by a quantitative assessment strategy (EB-NQAS). The EB-NQAS group (n=75) received personalized care plans developed by a dedicated nursing team. These plans were based on quantitative symptom assessment using the Edmonton Symptom Assessment Scale (ESAS) and incorporated evidence-based interventions for pain management (e.g., graded approach, music therapy, opioids), fatigue (e.g., activity plans, sleep optimization), nausea/vomiting prevention (e.g., prophylactic antiemetics, ginger, dietary advice), and psychological support (e.g., cognitive-behavioral therapy). Care plans were dynamically evaluated and adjusted based on daily and weekly ESAS monitoring. The control group (n=75) received routine nursing care, including standard health education, psychological support, dietary guidance, and adverse effect management. The study compared the effects of EB-NQAS versus routine nursing on CRF, self-management ability, QoL, and adverse events over a 3-month intervention period in 150 randomized lung cancer patients.
