The relationship between cancer-related fatigue, quality of life and pain among cancer patients.

ABSTRACT

Objectives: This study aimed to select patients with cancer-related pain to further analyze the relationship between pain severity, fatigue severity, and quality of life. Methods: A cross-sectional study was conducted. A convenience sampling method was used to select 224 patients with cancer-related pain who were undergoing chemotherapy and met the inclusion criteria in two hospitals of two provinces from May to November 2019. All participants were invited to complete a general information questionnaire, the Brief Fatigue Inventory (BFI), the Numerical Rating Scale (NRS) for pain intensity, and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30). Results: In the 24 h before completing the scales, 85 patients (37.9%) had mild pain, 121 (54.0%) had moderate pain, and 18 (8.0%) had severe pain. In addition, 92 (41.1%) patients had mild fatigue, 72 (32.1%) had moderate fatigue, and 60 (26.8%) had severe fatigue. Most patients with mild pain only experienced mild fatigue, and their quality of life was also at a moderate level. Patients with moderate and severe pain mostly had moderate or higher levels of fatigue and a lower quality of life. There was no correlation between fatigue and quality of life in patients with mild pain (r = -0.179, P = 0.104). There was a correlation between fatigue and quality of life in patients with moderate and severe pain (r = -0.537, P < 0.01; r = -0.509, P < 0.05). Conclusions: Patients with moderate and severe pain have more fatigue symptoms and lower quality of life than those with mild pain. Nurses should pay more attention to patients with moderate and severe pain, explore the interaction mechanism between symptoms, and carry out joint symptom intervention to improve the quality of life of patients.
