Legal aspects of chronic opioid therapy.

Although many Americans suffer from undertreated pain, the regulatory and legal environment for the use of opioids in pain relief is currently in a state of flux. The federal government's efforts to curb drug abuse have complicated the use of opioids for pain relief. Recent actions by the US Drug Enforcement Agency have added to an atmosphere of mistrust and confusion and have increased physician concerns about increased scrutiny and legal, regulatory, or administrative sanctions. Despite a disturbing shift in regulatory authority over opioid analgesics away from health agencies and toward law enforcement agencies, recent state policies and guidelines from national medical organizations are playing an important role in promoting the use of opioids for pain treatment and helping to reduce practitioners' concerns over regulatory oversight. Current and future trends concerning the legal and regulatory aspects of chronic opioid treatment are discussed in this article.

Racial/ethnic differences in FIM scores and length of stay for underinsured patients undergoing stroke inpatient rehabilitation.

OBJECTIVE: To explore racial/ethnic differences in FIM data from admission to discharge in underinsured patients undergoing inpatient stroke rehabilitation. DESIGN: This is a retrospective analysis of the Uniform Data System for Medical Rehabilitation (UDSMR) database of an inpatient rehabilitation unit of a county hospital in a large urban city. Data included 171 adult patients admitted to the stroke rehabilitation unit between January 2000 and October 2003. Main outcome measures included admission and discharge total FIM score, FIM gain, FIM efficiency, and length of stay (LOS). Data were analyzed using chi analyses, t tests, univariate analysis of variance, binary logistic regression, and hierarchical multiple regression. RESULTS: Data from 68 Hispanic, 83 black, and 20 white patients were included in the study. Univariate tests revealed that race/ethnicity groups differed significantly on admission FIM score (F=5.38, P<0.005), FIM gain (F=4.35, P<0.014), and FIM efficiency (F=3.42, P<0.035). Post hoc pairwise comparisons revealed that Hispanics had lower admission FIM scores than blacks (58.9 vs. 68.9). However, Hispanics had higher FIM gain scores than blacks (26.8 vs. 21.5). Race/ethnicity was not significantly related to age, gender, side of stroke, type of stroke, time from onset of stroke to rehabilitation admission, discharge FIM score, or LOS. Multiple regression analyses revealed that after controlling for all other available factors, race/ethnicity accounted for a significant amount of additional variance in admission FIM score (5.8%) and FIM efficiency (4.6%), but not in discharge FIM score, FIM gain, or LOS. Race/ethnicity was not predictive of discharge disposition. CONCLUSIONS: Differences in functional independence at admission to poststroke rehabilitation and the average daily improvement in function are related, in part, to patients' race/ethnicity. Differences in change in functional independence from admission to discharge (FIM gain) are not related to race/ethnicity once other factors, particularly admission FIM score, are taken into account. Future studies should identify reasons why Hispanics have lower admission FIM scores because demographic and stroke-related variables were not related to ethnicity yet have outcomes similar to blacks and whites at discharge.

Lumbar artery pseudoaneurysm in traumatic spinal cord injury: a case report.

Lumbar artery pseudoaneurysm is a rare vascular complication of trauma. This case report concerns a 24-year-old man with a lumbar-level spinal cord injury (SCI) secondary to a gunshot wound who developed severe exacerbation of low back and flank pain during inpatient rehabilitation. Diagnostic investigations at an acute care hospital revealed a left lumbar artery pseudoaneurysm. This was treated by transcatheter embolization, which resulted in a marked reduction in pain. The patient resumed inpatient rehabilitation without further complications. This case report highlights the importance of early diagnosis of lumbar artery pseudoaneurysm, a potentially fatal complication that can occur in patients with traumatic lumbosacral SCI. Physiatrists should include lumbar artery pseudoaneurysm in the differential diagnosis for back, flank, or abdominal pain in this patient population.

Comparison of dalteparin and enoxaparin for deep venous thrombosis prophylaxis in patients with spinal cord injury.

OBJECTIVE: To determine differences between dalteparin and enoxaparin in patients with spinal cord injury. DESIGN: This prospective, randomized, open-label study was performed as a multiple hospital trial in a large urban setting. A total of 100 patients with acute (<3 mo) spinal cord injury were recruited. A total of 95 patients met all inclusion criteria. Fifty received enoxaparin, and 45 received dalteparin. Main outcome measures included deep venous thrombosis, bleeding, compliance, Short Form-12 Health Status Survey, satisfaction, and medication/labor costs. Patients were randomized to receive 30 mg of enoxaparin subcutaneously every 12 hr or 5000 IU of dalteparin subcutaneously once daily. Prophylaxis was continued for 3 mo for motor-complete and 2 mo for motor-incomplete patients. RESULTS: Six percent of the patients developed deep venous thrombosis while receiving enoxaparin and 4% while receiving dalteparin (chi2 = 0.44, df = 1, P = 0.51). Four percent developed bleeding while receiving dalteparin and 2% while receiving enoxaparin (chi2 = 0.13, df = 1, P = 0.72). No differences were noted in compliance, health status, or most of the satisfaction measures. It was, however, noted that after being discharged home, the patients receiving enoxaparin rated the shots significantly more inconvenient (two injections per day) compared with taking three pills per day, than those receiving dalteparin (one injection per day, P < 0.05). The cost of the medication was 1101 US dollars/mo for enoxaparin (two injections per day) and 750 US dollars/mo for dalteparin (one injection per day). CONCLUSION: Similar compliance, health status, deep venous thrombosis, and bleeding rates were found between dalteparin and enoxaparin.
