Why patients are afraid of opioid analgesics: a study on opioid perception in patients with chronic pain.

INTRODUCTION    Opiophobia is deemed one of the key barriers in effective pain management. OBJECTIVES    The study aimed to assess the overall perception of opioids in cancer patients treated for chronic pain, as well as to determine the nature of their most common related fears. PATIENTS AND METHODS     The study included 100 palliative care patients who suffered from chronic cancer or noncancer pain. Initially, they had to complete a survey exploring their knowledge on analgesics and potential fear of using opioids. The second phase was based on in‑depth interviews with 10 palliative care patients suffering from cancer pain who were reluctant to use opioids. RESULTS     Of the 100 patients, 43 expressed concerns over commencing the treatment with opioids. Fear was reported more often in patients already on strong opioids, who either overtly expressed it (group C) or not (group B), as compared with patients treated with weak opioids (group A) (50%, 48%, and 19% of groups C, B, and A, respectively). The main concerns were drug addiction, fear of death or dying, and undesirable side effects. A qualitative study revealed similar types of fear among patients expressing concerns prior to being put on strong opioids. CONCLUSIONS    Opiophobia seems to be common among palliative care patients (up to 50%) treated with strong opioids. They mainly fear drug addiction, undesirable effects, and death or dying. Better awareness of patients' preconceptions about opioids may become instrumental to alleviating their suffering through enhanced pain management.
