RESUMO
BACKGROUND: Opioids are increasingly prescribed for chronic noncancer pain across the developed world. Clinical guidelines for management of these patients focus on over-use. However, research into other types of long-term medication indicates that many patients minimize drug use whenever possible. OBJECTIVE: To identify the varying influences on patients' decisions about their use of prescribed opioids and explore whether concepts of resistance and minimization of intake apply to these patients. DESIGN: A multiprofessional team performed a qualitative interview study using the constant-comparative method. Patient's decision making was explored in depth and with a thematic analysis utilizing a published "Model of medicine-taking." SETTING AND PARTICIPANTS: A purposive sample of 20 participants drawn from two pain clinics in Melbourne, Australia. The sample was biased toward patients interested in nonmedication pain management options. FINDINGS: Patients' needs to obtain relief from severe pain, maintain function, and minimize side effects could lead to under-use as well as over-use of prescribed opioids. In keeping with the published Model of medicine-taking, resistance to taking opioids was a common and important influence on behavior. In the face of severe chronic pain, many participants used a variety of strategies to evaluate, avoid, reduce, self-regulate, and replace opioids. Furthermore, participants perceived a resistance to opioids within the system and among some healthcare professionals. This sometimes adversely affected their adherence. CONCLUSIONS: Both patients and doctors exhibit aspects of resistance to the use of prescribed opioids for chronic noncancer pain, suggesting that this shared concern could be the basis of a productive therapeutic alliance to improve communication and shared decision making. SUMMARY: Clinical guidelines for opioids use for chronic noncancer pain focus on over-use. Our qualitative interview study found that many patients resisted and minimized the use of opioids. Using a published "Model of medicine-taking," we identified various influences on patient decision making. Both patients and doctors had concerns about using opioids for chronic noncancer pain. These could be the basis of a productive therapeutic alliance to improve communication and shared decision making.
