Abstract
Background and objective: Cancer patients treated with palliative intent often report anxiety. Anxiety is associated with dyspnoea, cancer pain, and reduced quality of life. Limited knowledge on variability and treatment effects warranted exploring factors associated with improvement in anxiety for hospitalised palliative cancer patients.
Methods: This study is a cross-sectional secondary analysis. All patients admitted to an acute palliative care unit for one year were assessed and 164 patients satisfied the study inclusion criteria. The patients reported self-registered symptom intensities using the 11-point numeric rating scale. Demographic variables, patient reports, and medical management were analysed for associations with anxiety.
Results: At admission, 37.8% of the patients reported moderate or severe anxiety, and of these 43.6% used benzodiazepines. The corresponding numbers for benzodiazepine use were 35.1% and 24.4% for patients with mild and no anxiety, respectively. Of all patients, 26.8% reported improved anxiety during their hospital stay. More patients with moderate or severe anxiety at admission reported improved anxiety during hospitalisation (50.0%) compared to the corresponding patients with mild anxiety (22.8%). Patients with moderate or severe anxiety reported less improvement in pain compared to patients with mild anxiety. Improved dyspnoea was the only factor statistically associated with improvement in anxiety, both for patients reporting mild anxiety and moderate and severe anxiety. Thirty-seven-point-1% of patients with moderate or severe anxiety at admission received no benzodiazepine treatment during the hospital stay. Patients receiving midazolam had more anxiety at admission, were younger, and had poorer performance status. Median dose and interquartile range [IQR] of midazolam in these patients were 2 mg/24 h [IQR: 2.0-6.0].
Conclusion: Improved dyspnoea was associated with reduced anxiety; however, the use of benzodiazepines was not.
