Evaluation of drug provocation test–related anxiety in patients with drug hypersensitivity
2016
Abstract Background Drug provocation tests (DPTs) are important in the treatment of patients with drug hypersensitivity (DH), but they carry certain hypersensitivity reaction risks, which lead to procedure-related concerns in patients. Objective To investigate DPT-related anxiety and its effect on long-term use of tested drugs. Methods The study included patients who underwent DPT from July 1, 2009, to July 1, 2012. After recording the patients' history and characteristics, a variety of psychiatric (Hospital Anxiety and Depression Scale, Panic and Agoraphobia Scale, and the Maudsley Obsessive-Compulsive Inventory) and quality-of-life (36-item Short Form Health Survey) tests were performed. DPT-related anxiety was also evaluated using a visual analog scale. The patients were requestioned about whether they had used the tested drug within 1 year. Results A total of 126 patients were included in the study. According to the Hospital Anxiety and Depression Scale, 23.4% and 30.6% of the patients had depression and anxiety symptoms, respectively. The mean (SD) visual analog scale anxiety scores after a negative DPT result were lower than those before DPTs (2 [2.5] after vs 5.2 [3.4] before; P Conclusion Our findings suggest that DPTs in themselves cause significant anxiety in patients with DH. Importantly, anxiety levels decreased after a negative test result. However, our results also suggested that a negative DPT result is not convincing enough for some patients to use the tested drug when needed in the future. Therefore, supporting strategies appear to be the most effective way to eliminate DH-related anxiety of patients.
