ReviewTherapeutic options for the treatment of postherpetic neuralgia: a systematic review.
Postherpetic neuralgia (PHN) is a chronic and painful condition that may result in significant disturbances to normal activities and decreases in the quality of life for those affected. Despite the availability of several first- and second-line treatment options, many patients may experience refractory pain. The objectives of this review were to summarize evidence for Food and Drug Administration (FDA)-approved and off-label therapies for the treatment of PHN and to present gaps in the current literature for future research focus. ⋯ However, evidence regarding the comparative effectiveness of these treatment alternatives is lacking. In order to choose the optimal treatment, providers should consider issues related to efficacy, safety, and tolerability in conjunction with patient goals, preferences, and adherence issues. Evidence from randomized or observational studies that directly compare agents with each other should help to inform treatment choices.

Observational StudyTapentadol prolonged release for severe chronic pain: results of a noninterventional study involving general practitioners and internists.
This noninterventional, prospective study investigated the administration of tapentadol prolonged release (PR; the dosage form described in this article is commercially available in Germany as Palexia retard; Grünenthal GmbH, Aachen) for severe chronic pain in routine clinical practice over a 3-month period. Effectiveness analyses included data from 3134 patients; 1331 received World Health Organization (WHO) Step III pretreatment. A total of 97.8% of patients received long-term analgesic pretreatment (42.5% with strong opioids). ⋯ Significant decreases in pain-related impairment of daily activities and improvements in quality of life (descriptive P value ≤.001) were observed with tapentadol PR with good tolerability. Tapentadol PR was effective for various pain indications in patients previously receiving strong opioids (67.2% achieved clinically relevant pain relief). Tapentadol PR can be considered an alternative therapy to classical opioids for treatment of severe chronic pain.

Characterization of patients undergoing total hip arthroplasty in a real-world setting and pain-related medication prescriptions for management of postoperative pain.
This observational study characterized medication use in the immediate postoperative period among patients undergoing total hip arthroplasty (THA) at an academic medical center, and evaluated pain (0-10 numerical pain rating scale [NPRS]; 0 = no pain, 10 = worst pain that the patient can imagine), function (Harris Hip Score [HSS]and Lower Extremity Function Scale [LEFS]), and health-related quality of life (SF-36). Study patients (N = 115; 59% female; average age 61.3 ± 12.0 years; mean BMI of 29.9 ± 6.9 kg/m2) who underwent THA between September 1, 2008, and November 30, 2010, and met study inclusion criteria were drawn from the University of Utah Orthopedic Clinic database. The most common comorbidities in these patients were osteoarthritis, hypertension, and chronic back pain. ⋯ Opioids and celecoxib continued to be commonly prescribed at discharge. Pain was improved at a 6-week follow-up (mean change −3.3 ± 3.3 points), as were HSS and LEFS, with mean changes of 19.9 ± 24.2 and 8.7 ± 16.9 points (P < .01 for both), respectively. Although SF-36 scores were also improved, these scores were significantly lower relative to normative values for the US general population as well as relative to individuals having both osteoarthritis and hypertension.

Opioid use in end-of-life care in patients with interstitial pneumonia associated with respiratory worsening.
The authors investigated the treatment outcome of patients with severe interstitial pneumonia (IP) who received opioids during end-of-life care. Twenty-two consecutive patients were retrospectively evaluated before and after continuous administration of opioids for 24 hours. All subjects died within 21 days; the mean survival period after opioid administration was 5.6 days. ⋯ The other 16 patients showed both positive and negative effects as expected. Clinicians should assess dyspnea prior to opioid administration, since the purpose of the opioid administration is to relieve dyspnea. Dyspnea should be monitored and recorded in routine clinical practice, at least after hospitalization.

Estimates of charges associated with emergency department and hospital inpatient care for opioid abuse-related events.
The economic burden of prescription opioid abuse is substantial; however, no study has estimated the monetary burden of hospital services (emergency department [ED] and inpatient) using a single, nationally representative database. We sought to estimate total and average (adjusted for demographic and clinical factors) charges billed for opioid abuse-related events, and magnitude of difference in charges between ED visits resulting in inpatient admission to the same hospital and treat-and-release ED visits in the United States. We used the 2006, 2007, and 2008 files of the Healthcare Cost and Utilization Project's Nationwide Emergency Departments Sample (HCUP-NEDS) to identify events and charges assigned opioid abuse, dependence, or poisoning ICD-9-CM (International Classification of Diseases, 9th Revision, Clinical Modification) diagnosis codes (304.0X, 304.7X, 305.5X, 965.00, 965.02, 965.09). ⋯ Compared with events covered by private insurance, mean charges for Medicare- and Medicaid-covered events were higher (t = 28.14, P < .001; t = 6.42, P < .001, respectively), whereas self-paid events had significantly lower charges (t = -11.14, P < .001). ED visits resulting in subsequent inpatient admission had approximately 6 times higher charges than treat-and-release visits. This study provides estimates of differences in hospital costs of opioid abuse by insurance status, resulting in a better understanding of the economic burden of opioid abuse on the health care system.
