Exploring beliefs and practice of opioid prescribing for persistent non-cancer pain by general practitioners

Persistent non-cancer pain is a common reason for consultation in primary care but treatment options, including non-opioid analgesics, are limited, and neither strong evidence nor established guidelines address when and how primary care doctors should prescribe opioid analgesics for persistent non-cancer pain. The aim of this study was to investigate associations between doctors' prescribing patterns for persistent non-cancer pain in primary care and their personal and practice characteristics and beliefs about appropriateness and risks of opioids. A pilot survey sampled beliefs concerning the need for and risks of opioid prescribing for persistent non-cancer pain among volunteers from primary care practices and postgraduate educational events, using a self-report questionnaire, and related these beliefs to their reported opioid prescribing. One quarter of the sample prescribed no opioids for persistent non-cancer pain. Prescribing opioids was predicted by moderate belief in the appropriateness of opioids within certain constraints, and to a lesser extent by younger age. While some beliefs distinguished prescribers from non-prescribers, predicting non-prescribing was poor. Both prescribers and non-prescribers expressed concern about the risks of opioids. In addition, most primary care doctors were dissatisfied with their training on pain; few had prescribing guidelines; and neither training nor guidelines influenced prescribing. In conclusion, whether or not GPs prescribe opioids for persistent non-cancer pain is mainly determined by their personal beliefs about appropriateness of opioids for this problem.
