Randomized Controlled TrialIncreases in the Use of Prescription Opioid Analgesics and the Lack of Improvement in Disability Metrics Among Users.
In the United States, use of oral opioid analgesics has been associated with increasing rates of addiction, abuse, and diversion. However, little is known about the recent national use of non-illicit prescription opioid analgesics (those prescribed in a physician-patient relationship), the primary source of these drugs for the general US population. Our primary objective was to examine trends in the use of prescription opioid analgesics in the United States and to identify defining characteristics of patient users of prescribed opioids from 2000 to 2010. ⋯ The use of prescription opioid analgesics among adult Americans has increased in recent years, and this increase does not seem to be associated with improvements in disability and health status among users. On a public health level, these data suggest that there may be an opportunity to reduce the prescribing of opioid analgesics without worsening of population health metrics.

Are Patients Satisfied After Peripheral Nerve Blockade? Results From an International Registry of Regional Anesthesia.
Peripheral nerve blockade (PNB) is associated with superior outcomes compared with opioids; however, little is known regarding patients' perceptions of the care they have received. Patient satisfaction is emerging as an important indicator of quality of health care, and identifying deficiencies in discrete aspects of satisfaction may allow targeted interventions to improve quality. In this study, we analyze data relevant to patient satisfaction from the International Registry of Regional Anesthesia. The primary objective of this analysis was to report the results of a patient-satisfaction questionnaire and to determine predictors associated with unwillingness to have PNB repeated in the case of future surgery. ⋯ A high proportion of survey respondents were willing to undergo repeat PNB in case of future surgery and were satisfied with their anesthetic care. Targeted interventions to improve quality of PNB should be aimed at improving comfort, information provision, and physician-patient interaction.

Characteristics of Chronic Pain Patients Who Take Opioids and Persistently Report High Pain Intensity.
The use of self-report questionnaires to detect characteristics of altered central pain processing, as seen in centralized pain disorders such as fibromyalgia, allow for the epidemiological studies of pain patients. Here, we assessed the relationship between reporting high levels of pain while taking opioids and the presence of characteristics associated with centralized pain. ⋯ Our findings suggest that patients with persistently high pain scores despite opioid therapy are more likely than those with lower levels of pain to present with characteristics associated with having centralized pain. This study cannot determine whether these characteristics were present before (fibromyalgia-like patient) or after the initiation of opioids (opioid-induced hyperalgesia). Regardless, patients with a centralized pain phenotype are thought to be less responsive to opioids and may merit alternative approaches.
