Chronic pain affects both psychological and physical functioning, and is responsible for more than $60 billion in lost productivity annually in the United States. Although previous studies have demonstrated racial disparities in opioid treatment, there is little evidence regarding disparities in treatment of chronic noncancer pain (CNCP) and the role played by physician specialty in these disparities. ⋯ Our findings suggest that, in our study population, black beneficiaries with CNCP are less likely than whites to fill prescriptions for opioid analgesics as a function of their provider's specialty. Although race-based differences in patients filling opioid prescriptions have been noted in previous studies, this is the first study that clearly demonstrates these disparities by provider specialty.

To determine perioperative treatments and events associated with Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey responses. ⋯ These data suggest that demographic factors, preadmission medications, and PACU pain scores but not analgesic medications are associated with patient satisfaction with regards to both pain management and overall satisfaction.

Current research on the risk of opioid analgesics with drug overdose does not account for the total morphine equivalent dose (MED) of opioids filled by a patient. In this study, time from first opioid prescription until drug overdose was examined for 206,869 privately insured patients aged 18 to 64 with noncancer pain and ≥2 filled prescriptions for Schedule II or III opioids from January 2009 to July 2012. Opioid therapy was examined in 6-month intervals including 6 months before an overdose and categorized as mean daily MED (0, 1-19, 20-49, 50-99, ≥100 mg) and total MED divided at top quartile (0, 1-1,830, >1,830 mg). Survival analysis was used, adjusting for demographics, clinical conditions, and psychoactive drugs. Relative to no opioid therapy, persons at highest risk for overdose (adjusted hazard ratios of 2-3) received a daily MED of ≥100 mg regardless of total dose or a daily MED of 50 to 99 mg with a high total MED (>1,830 mg). The hazard ratio was significantly lower (1.43, 95% confidence interval = 1.15-1.79) for 50 to 99 mg daily MED with a lower total MED (≤1,830 mg), whereas hazard ratios for lower daily MEDs did not differ by total dose. This analysis suggests that clinicians should consider total MED to assess risk of overdose for persons prescribed 50 to 99 mg daily MED. ⋯ When addressing risks for drug overdose, this analysis supports the need for clinicians, administrators, and policy makers to monitor not only daily opioid dose but also total dose for patients receiving 50 to 99 mg daily MED.

Opioids are well known for their robust analgesic effects. Chronic activation of mu opioid receptors (MOPs) is, however, accompanied by various unwanted effects such as analgesic tolerance. Among other mechanisms, interactions between MOPs and delta opioid receptors (DOPs) are thought to play an important role in morphine-induced behavioral adaptations. ⋯ As opposed to NTI, 7-benzylidenenaltrexone and naltriben were reported to be selective DOP subtype 1 and DOP subtype 2 antagonists, respectively. Interestingly, naltriben but not 7-benzylidenenaltrexone was able to attenuate the development of morphine analgesic tolerance in inflamed rats. Altogether, our results suggest that targeting of DOP subtype 2 with antagonists provides a valuable strategy to attenuate the analgesic tolerance that develops after repeated morphine administration in the setting of chronic inflammatory pain.

Medical and Psychiatric Effects of Long-Term Dependence on High Dose of tramadol.
Tramadol dependence has been studied recently after large-scale exposure. Although tramadol dependence has increased rapidly in Egypt since 2004, no studies have evaluated the effect of high dose long-term tramadol dependence. ⋯ Tramadol dependence on high dose could be physically safe to some limit, but psychiatrically it has many side effects.
