Anxiety and depression among haematological cancer patients attending treatment centres: prevalence and predictors

Background This study aimed to: (1) estimate the prevalence of anxiety and/or depression among haematological cancer patients attending treatment centres; and (2) explore the demographic, disease and treatment characteristics associated with anxiety and/or depression. Methods A cross-sectional study was conducted with outpatients from three haematology clinics in Australia. Patients with a confirmed diagnosis of haematological cancer were approached by a research assistant while waiting for their appointment and invited to participate in the survey. Participants completed the Hospital Anxiety and Depression Scale (HADS) and self-reported demographic, disease and treatment characteristics. Results Questionnaires from 304 participants were returned. Twenty-seven percent of patients reported anxiety and 17% reported depression. Specifically, 15% reported anxiety without depression, 5% reported depression without anxiety, and 12% reported comorbid anxiety and depression. Participants who had to relocate to receive treatment had almost three times the odds of reporting anxiety and/or depression compared to those who did not have to move. Former smokers also had significantly higher odds of reporting anxiety and/or depression. Limitations The HADS is likely to have produced some false positives and false negatives when compared with gold standard structured clinical interviews for assessing psychological morbidity. Conclusions Approximately 20% of haematological cancer patients attending outpatient clinics may experience clinically significant levels of anxiety and/or depression. Providing additional tailored support to patients who have had to relocate for treatment, and to former smokers, may help to reduce anxiety and depression among these subgroups.
