Objective The aims of the present study were to describe the use, and barriers to the use, of non-medication pain therapies and to identify the demographic and clinical correlates of different non-opioid pain treatments. Methods The study was performed on a cohort (n=1514) of people prescribed pharmaceutical opioids for chronic non-cancer pain (CNCP). Participants reported lifetime and past month use of healthcare services, mental and physical health, pain characteristics, current oral morphine equivalent daily doses and financial and access barriers to healthcare services. ⋯ Having private health insurance was associated with increased use of non-opioid treatments for pain, highlighting the importance of considering how treatments are paid for and potential financial barriers to effective treatments. What are the implications for practitioners? Patients' beliefs and financial barriers may affect the uptake of different treatments. Many patients may be using complementary and alternative approaches with limited evidence to support their use, highlighting the need for clinicians to discuss with patients the range of prescribed and non-prescribed treatments they are accessing and to help them understand the benefits and risks of treatments that have not been tested sufficiently, or have inconsistent evidence, as to their efficacy in improving pain outcomes.

Rates of chronic non-cancer pain are increasing worldwide, with concerns regarding poorer access to specialist treatment services in remote areas. The current study comprised the first in-depth examination of use and barriers to access of health services in Australia according to remoteness. ⋯ Perceived communication, access, and financial barriers to healthcare indicate the need for increased efforts to address geographic inequality in pain treatment.

To examine laxative use by individuals in hospice who were taking opioids during the last week of life. ⋯ In 2007, slightly more than half of older adults in hospice who were taking opioids used laxatives during the last week of life. Recent quality indicators from the Centers for Medicare and Medicaid Services recommend laxative treatment when opioid therapy is initiated to prevent opioid-induced constipation and are intended to improve laxative use in individuals in hospice treated with opioids.

Microinjection of morphine into the periaqueductal gray (PAG) produces antinociception. In vitro slice recordings indicate that all PAG neurons are sensitive to morphine either by direct inhibition or indirect disinhibition. We tested the hypothesis that all PAG neurons respond to opioids in vivo by examining the extracellular activity of PAG neurons recorded in lightly anesthetized and awake rats. ⋯ Changes in activity caused by morphine were surprisingly modest (a median increase from 0.7 to 1.3Hz). The small inconsistent effects of morphine are in stark contrast to the large changes produced by morphine on the activity of rostral ventromedial medulla (RVM) neurons or the widespread inhibition and excitation of PAG neurons treated with opioids in in vitro slice experiments. The relatively modest effects of morphine in the present study suggest that morphine produces antinociception by causing small changes in the activity of many PAG neurons.

Aim To identify nurses' knowledge of pain and its management in older people in acute hospitals. Method A quantitative, descriptive, cross-sectional design was used to survey a convenience sample of nurses. Data were collected using the Pain in the Elderly Questionnaire. ⋯ Less than 25% of nurses had recent pain management education. Conclusion These findings indicate a knowledge deficit among nurses regarding pain and its management in older people, particularly in relation to opioid management. To improve pain management, nurses caring for older people would benefit from participation in an education programme with clinical application, such as expert-led, real-life or simulation demonstrations rather than lecture/discussion format only.
