Abstract
UNLABELLED Two issues relating to prescription opioid nonmedical use that to our knowledge have not been comprehensively addressed in the peer-reviewed literature are discussed: Motives for nonmedical use and the extent of nonmedical use of prescription opioids in other countries. The United States' national annual survey on illicit drug use in the general population (National Survey on Drug Use and Health) asks respondents whether they have used prescription opioids for nonmedical purposes but does not assess motives for such use. By not assessing motives, nonmedical users who use only for pain relief and nonmedical users who have other motives for use are grouped together, but 2 recent epidemiological studies suggest that these 2 groups may differ in a propensity to have substance use-related problems. We suggest that the survey add a question that assesses motives for nonmedical use. Regarding whether countries besides the United States have problems associated with nonmedical use of prescription opioids, after searching for epidemiological surveys and other materials potentially relevant to this issue, we were unable to determine the extent of nonmedical use of prescription opioids in other countries or draw cross-national comparisons. We suggest that more countries include specific questions about nonmedical use of prescription opioids in their national epidemiological surveys. PERSPECTIVE We believe that critical information surrounding the nonmedical use of prescription opioids is not being gathered. Such information would allow for a better understanding of the problem. We invite discussion and commentaries regarding the issues we raise to more effectively address this public health issue.

Abstract
The profile of opioid dependence in the United States is changing. Abuse of prescription opioids is more common than that of illicit opioids: Recent data indicate that approximately 1.6 million persons abuse or are dependent on prescription opioids, whereas 323,000 abuse or are dependent on heroin. Despite this prevalence, nearly 80% of opioid-dependent persons remain untreated. One option for expanding treatment is the use of buprenorphine and the buprenorphine-naloxone combination. Buprenorphine is a partial opioid agonist that can be prescribed by trained physicians and dispensed at pharmacies. This article addresses the clinical presentation of a patient with opioid dependence and describes the relatively new practice of office-based treatment with buprenorphine-naloxone. The different components of treatment; the role of the physician who provides this treatment; and the logistics of treating this growing, multifaceted patient population are also examined.

Abstract
OBJECTIVE The goal of this paper was to examine the relationship between history of substance use disorder (SUD) and self-reported prescription medication misuse in 127 primary care patients who receive opioid medications for treatment of chronic pain. METHOD Participants completed measures of pain location, pain intensity, disability due to pain, and misuse of prescription medications. Other measures included demographic characteristics, psychiatric symptomatology and quality of life. RESULTS Seventy-eight percent of participants reported at least one indicator of medication misuse in the prior year. After adjusting for age and clinical factors (pain severity, depression severity, current alcohol or substance use disorder), participants with SUD history were significantly more likely than participants without SUD history to report borrowing pain medications from others (OR=6.62, 95% CI=1.4-30.7) and requesting an early refill of pain medication (OR=3.86, 95% CI=1.5-9.6). CONCLUSIONS Misuse of prescription medications is a concern among primary care patients with chronic pain. Participants with a lifetime history of SUD are more likely to endorse some aberrant medication-related behaviors. Patients with SUD histories should be carefully evaluated for medication misuse potential and may require more intense assessment and follow-up.

Abstract
BACKGROUND Little is known about whether internal medicine residents find pain management agreements (PMAs) useful or whether PMA use is associated with more positive attitudes toward patients with chronic noncancer pain (CNCP). METHODS We surveyed all internal medicine residents at Rhode Island Hospital regarding whether they found PMAs useful, what percentage of their patients taking chronic opioids had a signed PMA, and their attitudes toward and experiences with managing CNCP. RESULTS Survey response rate was 89% (110/124). Ninety percent of respondents reported finding PMAs useful. A majority of respondents reported that PMAs were at least somewhat helpful for reducing multiple prescribers (76%), reducing requests for early refills (67%), reducing calls and pages from patients (57%), making it easier to discuss potential problems associated with chronic opioid use (73%), and making it easier to identify patients who are abusing pain medications (66%). Residents who reported greater use of PMAs reported a greater sense of preparation (r=0.20, P=0.04), greater confidence (r=0.18, P=0.06), and a greater sense of reward (r=0.24, P=0.02) for managing CNCP. In a multivariate analysis, PMA use was significantly associated with greater sense of preparation and greater sense of reward for managing CNCP. CONCLUSIONS Among internal medicine residents, PMA use was associated with more positive attitudes toward CNCP management.

Abstract
OBJECTIVES Physicians frequently express dissatisfaction about caring for patients with chronic pain and frequently report that inadequate training and concern about addiction are impediments to prescribing opioids. Elderly patients with chronic pain may be at increased risk of experiencing uncontrolled pain and this patient population is increasingly being cared for by geriatricians rather than internists. We sought to determine if there is a differential impact on internists and geriatricians of the factors that adversely affect attitudes toward opioid prescribing. METHODS Anonymous survey of geriatric and internal medicine physicians at a large urban academic medical center about their beliefs and behaviors regarding opioid prescribing. RESULTS One hundred thirty-two of 187 physicians completed the survey for an overall response rate of 71%. Controlling for level of training, internists were more likely to be concerned about illegal diversion (adjusted odds ratio=10.0, P=0.004), were more concerned about causing addiction (38% vs. 0%, P<0.001), and were more likely to be concerned about their inability to prescribe the correct opioid dose (adjusted odds ratio=11.1, P=0.020). DISCUSSION Factors shown to have an adverse affect on opioid prescribing disproportionately impact on the attitudes of internists compared with geriatricians. Further research is needed to determine if there is also a differential impact on how internists care for their elderly patients with chronic pain.

Abstract
OBJECTIVE To determine whether individuals who use prescribed opioids for chronic noncancer pain have higher rates of any opioid misuse, any problem opioid misuse, nonopioid illicit drug use, nonopioid problem drug use, or any problem alcohol use, compared with those who do not use prescribed opioids. METHODS Respondents were from a nationally representative survey (N = 9,279), which contained measures of regular use of prescribed opioids, substance use problems, mental health disorders, physical health, pain, and sociodemographics. RESULTS In unadjusted models, compared with nonusers of prescription opioids, users of prescription opioids had significantly higher rates of any opioid misuse (odds ratio [OR] = 5.48, P < 0.001), problem opioid misuse (OR = 14.76, P < 0.001), nonopioid illicit drug use (OR = 1.73, P < 0.01), nonopioid problem drug use (OR = 4.48, P < 0.001), and problem alcohol use (OR = 1.89, P = 0.04). In adjusted models, users of prescribed opioids had significantly higher rates of any opioid misuse (OR = 3.07, P < 0.001) and problem opioid misuse (OR = 6.11, P < 0.001) but did not have significantly higher rates of the other outcomes. CONCLUSIONS Users of prescribed opioids had higher rates of opioid and nonopioid abuse problems compared with nonusers of prescribed opioids, but these higher rates appear to be partially mediated by depressive and anxiety disorders. It is not possible to assign causal priority based on our cross-sectional data, but our findings are more compatible with mental disorders leading to substance abuse among prescription opioid users than prescription opioids themselves prompting substance abuse iatrogenically. In patients receiving prescribed opioids, clinicians need to be alert to drug abuse problems and potentially mediating mental health disorders.

Abstract
OBJECTIVE We attempted to identify psychological comorbidities that are associated with the propensity for prescription opioid abuse. INTERVENTIONS Patients presenting to an emergency department seeking opioid refills for chronic pain were evaluated with five validated self-report instruments and structured clinical interviews. The potential for prescription opioid abuse was modeled with multiple regression analysis using depression, anxiety disorders, personality disorder, and addiction as independent variables. RESULTS Of the 113 patients studied, 91 (81%) showed a propensity for prescription opioid abuse as determined by scores on the Screener and Opioid Assessment for Patients with Pain instrument. Depression, anxiety, and a history of substance were common and panic attacks, posttraumatic stress disorder, and personality disorders were also found, albeit less frequently. Panic attacks, trait anxiety, and the presence of a personality disorder accounted for 38% of the variance in the potential for prescription opioid abuse. CONCLUSIONS Patients in chronic pain should be assessed for psychological and addiction disorders because they are at increased risk for abusing opioids. They should also be referred for psychosocial treatment as part of their care, where appropriate.

Abstract
Opioid therapy for chronic noncancer pain (CNCP) is controversial due to concerns regarding long-term efficacy and adverse events (including addiction). We systematically reviewed the clinical evidence on patients treated with opioids for CNCP for at least six months. Of 115 studies identified by our search of eleven databases (through April 7, 2007), 17 studies (patients [n]=3,079) met inclusion criteria. Studies evaluated oral (studies [k]=7; n=1,504), transdermal (k=3; n=1, 993), and/or intrathecal (k=8; n=177) opioids. Many patients withdrew from the clinical trials due to adverse effects (oral: 32.5% [95% confidence interval (CI), 26.1%-39.6%]; intrathecal: 6.3% [95% CI, 2.9%-13.1%]; transdermal: 17.5% [95% CI, 6.5%-39.0%]), or due to insufficient pain relief (oral: 11.9% [95% CI, 7.8%-17.7%]; intrathecal: 10.5% [95% CI, 3.5%-27.4%]; transdermal: 5.8% [95% CI, 4.2%-7.3%]). Signs of opioid addiction were reported in only 0.05% (1/2,042) of patients and abuse in only 0.43% (3/685). There was an insufficient amount of data on transdermal opioids to quantify pain relief. For patients able to remain on oral or intrathecal opioids for at least six months, pain scores were reduced long-term (oral: standardized mean difference [SMD] 1.99, 95% CI, 1.17-2.80; intrathecal: SMD 1.33, 95% CI, 0.97-1.69). We conclude that many patients discontinue long-term opioid therapy due to adverse events or insufficient pain relief; however, weak evidence suggests that oral and intrathecal opioids reduce pain long-term in the relatively small proportion of individuals with CNCP who continue treatment.

Abstract
Development of working alliance was examined for 25 opioid-abusing pain patients and their therapists. Patients participated in an eight-session intervention based on adherence strategies and employment of a supportive, psychoeducational approach; methadone was prescribed for pain. Treatment goals included opioid analgesic adherence and decreasing pain, functional interference, and substance abuse. Patients and therapists completed the Helping Alliance Questionnaire-II following each treatment session. At baseline, scores of patients and therapists indicated good alliance. Patient alliance grew significantly over time regardless of addiction severity and independent of treatment outcomes. In contrast, therapist alliance grew only for patients without substance abuse comorbidity and/or who had good outcomes. Patients' and therapists' alliance scores were consistent during sessions focused on emotional bonds but diverged during sessions that demanded behavior change, suggesting that therapists may have reacted negatively to patients' lack of progress. Whether therapists' reactions to poor performers impacted subsequent patient outcomes is unknown but should be investigated.

Abstract
OBJECTIVE To measure the impact of a structured opioid renewal program for chronic pain run by a nurse practitioner (NP) and clinical pharmacist in a primary care setting. PATIENTS AND SETTING Patients with chronic noncancer pain managed with opioid therapy in a primary care clinic staffed by 19 providers serving 50,000 patients at an urban academic Veterans hospital. DESIGN Naturalistic prospective outcome study. INTERVENTION Based on published opioid prescribing guidelines and focus groups with primary care providers (PCPs), a structured program, the Opioid Renewal Clinic (ORC), was designed to support PCPs managing patients with chronic noncancer pain requiring opioids. After training in the use of opioid treatment agreements (OTAs) and random urine drug testing (UDT), PCPs worked with a pharmacist-run prescription management clinic supported by an onsite pain NP who was backed by a multi-specialty Pain Team. After 2 years, the program was evaluated for its impact on PCP practice and satisfaction, patient adherence, and pharmacy cost. RESULTS A total of 335 patients were referred to the ORC. Of the 171 (51%) with documented aberrant behaviors, 77 (45%) adhered to the OTA and resolved their aberrant behaviors, 65 (38%) self-discharged, 22 (13%) were referred for addiction treatment, and seven (4%) with consistently negative UDT were weaned from opioids. The 164 (49%) who were referred for complexity including history of substance abuse or need for opioid rotation or titration, with no documented aberrant drug-related behaviors, continued to adhere to the OTA. Use of UDT and OTAs by PCPs increased. Significant pharmacy cost savings were demonstrated. CONCLUSION An NP/clinical pharmacist-run clinic, supported by a multi-specialty team, can successfully support a primary care practice in managing opioids in complex chronic pain patients.

Abstract
Little is known about the extent of problems due to extramedical opioid analgesic use ('analgesic misuse') in the US general population. This study explores the distribution of the seven DSM-IV-defined past-year dependence symptoms in a total household sample of 7,810 past-year extramedical opioid analgesic users using the 2002-2003 National Survey on Drug Use and Health (NSDUH). We tested for differences in opioid analgesic dependence symptom profiles across four subgroups of opioid analgesic users, different levels of deviant behaviors, and presence/absence of serious mental health problems quantified by the Composite International Diagnostic Interview Short Form (CIDI-sf). Generalized Estimated Equations (GEE) models were used to analyze the data. The most common opioid analgesic dependence symptoms were 'tolerance' (17.0%) and 'salience' (13.3%). Opioid analgesic dependence symptom profiles were 'parallel' across the groups of past-year opioid analgesic users, across deviant behavior groups and across presence/absence of serious mental health problems. Extramedical use of opioid analgesics associated with prescription drug use, having high levels of deviant behaviors, and having serious mental health problems were more strongly associated with endorsement of opioid analgesics dependence symptoms.

Abstract
UNLABELLED The primary goal of this paper was to present a comprehensive picture of substance use disorders in a sample of patients receiving opioid therapy from their primary care physician. A second goal was to determine the relation of positive urine screens and aberrant drug behaviors to opioid use disorders. The study recruited 801 adults receiving daily opioid therapy from the primary care practices of 235 family physicians and internists in 6 health care systems in Wisconsin. The 6 most common pain diagnoses were degenerative arthritis, low back pain, migraine headaches, neuropathy, and fibromyalgia. The point prevalence of current (DSM-IV criteria in the past 30 days) substance abuse and/or dependence was 9.7% (n=78) and 3.8% (30) for an opioid use disorder. A logistic regression model found that current substance use disorders were associated with age between 18 and 30 (OR=6.17: 1.99 to 19.12), severity of lifetime psychiatric disorders (OR=6.17; 1.99 to 19.12), a positive toxicology test for cocaine (OR=5.92; 2.60 to 13.50) or marijuana (OR=3.52; 1.85 to 6.73), and 4 aberrant drug behaviors (OR=11.48; 6.13 to 21.48). The final model for opioid use disorders was limited to aberrant behaviors (OR=48.27; 13.63 to 171.04) as the other variables dropped out of the model. PERSPECTIVE This study found that the frequency of opioid use disorders was 4 times higher in patients receiving opioid therapy compared with general population samples (3.8% vs 0.9%). The study also provides quantitative data linking aberrant drug behaviors to opioid use disorders.

Abstract
BACKGROUND Chronic noncancer pain (CNCP) is a global issue, not only affecting individual suffering, but also impacting the delivery of health care and the strength of local economies. OBJECTIVES The current study (the Canadian Chronic Pain Study II [CCPSII]) was designed to assess any changes in the prevalence and treatment of CNCP, as well as in attitudes toward the use of strong analgesics, compared with a 2001 study (the CCPSI), and to provide a snapshot of the current standards of care for pain management in Canada. METHODS Standard, computer-assisted telephone interview survey methodology was applied in two segments, ie, a general population survey and a survey targeting randomly selected primary care physicians (PCPs) who treat moderate to severe CNCP. RESULTS AND DISCUSSION The patient-reported prevalence of CNCP within Canada has not markedly changed since 2001 but the duration of suffering has decreased. There have been minor changes in regional distribution and generally more patients receive medical treatment, which includes prescription analgesics. Physicians continue to demonstrate opiophobia in their prescribing practices; however, although this is lessened relating to addiction, abuse remains an important concern to PCPs. Canadian PCPs, in general, are implementing standard assessments, treatment approaches, evaluation of treatment success and tools to prevent abuse and diversion, in accordance with guidelines from the Canadian Pain Society and other pain societies globally, although there remains room for improvement and standardization.

Abstract
Patients with medically unexplained symptoms (MUS) have little or no demonstrable disease explanation for the symptoms, and comorbid psychiatric disorders are frequent. Although common, costly, distressed, and often receiving ill-advised testing and treatments, most MUS patients go unrecognized, which precludes effective treatment. To enhance recognition, we present an emerging perspective that envisions a unitary classification for the entire spectrum of MUS where this diagnosis comprises severity, duration, and comorbidity. We then present a specific approach for making the diagnosis at each level of severity. Although our disease-based diagnosis system dictates excluding organic disease to diagnose MUS, much exclusion can occur clinically without recourse to laboratory or consultative evaluation because the majority of patients are mild. Only the less common, "difficult" patients with moderate and severe MUS require investigation to exclude organic diseases. By explicitly diagnosing and labeling all severity levels of MUS, we propose that this diagnostic approach cannot only facilitate effective treatment but also reduce the cost and morbidity from unnecessary interventions.

Abstract
A central question in prescribing opioids for chronic non-cancer pain (CNCP) is how to best balance the risk of opioid abuse and dependence with the benefits of pain relief. To achieve this balance, clinicians need an understanding of the risk factors for opioid abuse, an issue that is only partially understood. We conducted a secondary data analysis of regional VA longitudinal administrative data (years 2000-2005) for chronic users of opioids for CNCP (n=15,160) to investigate risk factors for the development of clinically recognized (i.e., diagnosed) opioid abuse or dependence among these individuals. We analyzed four broad groups of possible risk factors: (i) non-opioid substance abuse disorders, (ii) painful physical health disorders, (iii) mental health disorders, and (iv) socio-demographic factors. In adjusted models, a diagnosis of non-opioid substance abuse was the strongest predictor of opioid abuse/dependence (OR=2.34, p<0.001). Mental health disorders were moderately strong predictors (OR=1.46, p=0.005) of opioid abuse/dependence. However, the prevalence of mental health disorders was much higher than the prevalence of non-opioid substance abuse disorders (45.3% vs. 7.6%) among users of opioids for CNCP, suggesting that mental health disorders account for more of the population attributable risk for opioid abuse than does non-opioid substance abuse. Males, younger adults, and individuals with greater days supply of prescription opioids dispensed in 2002 were more likely to develop opioid abuse/dependence. Clinicians need to carefully screen for substance abuse and mental health disorders in candidates for opioid therapy and facilitate appropriate treatment of these disorders.

Abstract
BACKGROUND The use of opioid medications to manage chronic pain is complex and challenging, especially in primary care settings. Medication contracts are increasingly being used to monitor patient adherence, but little is known about the long-term outcomes of such contracts. OBJECTIVE To describe the long-term outcomes of a medication contract agreement for patients receiving opioid medications in a primary care setting. DESIGN Retrospective cohort study. SUBJECTS All patients placed on a contract for opioid medication between 1998 and 2003 in an academic General Internal Medicine teaching clinic. MEASUREMENTS Demographics, diagnoses, opiates prescribed, urine drug screens, and reasons for contract cancellation were recorded. The association of physician contract cancellation with patient factors and medication types were examined using the Chi-square test and multivariate logistic regression. RESULTS A total of 330 patients constituting 4% of the clinic population were placed on contracts during the study period. Seventy percent were on indigent care programs. The majority had low back pain (38%) or fibromyalgia (23%). Contracts were discontinued in 37%. Only 17% were cancelled for substance abuse and noncompliance. Twenty percent discontinued contract voluntarily. Urine toxicology screens were obtained in 42% of patients of whom 38% were positive for illicit substances. CONCLUSIONS Over 60% of patients adhered to the contract agreement for opioids with a median follow-up of 22.5 months. Our experience provides insight into establishing a systematic approach to opioid administration and monitoring in primary care practices. A more structured drug testing strategy is needed to identify nonadherent patients.

Abstract
PURPOSE To assess internal medicine residents' confidence in, experiences with, and attitudes toward managing chronic nonmalignant pain (CNMP) in their outpatient practices. METHODS We surveyed internal medicine residents with regard to their experiences with and attitudes toward patients with CNMP. Mean responses across residency year of training were analyzed. RESULTS Sixty-three percent of respondents reported feeling somewhat or much less confident in managing CNMP than in managing diabetes. Confidence did not increase with level of training (p=.72). Sixty-three percent rated their preparation for managing patients with CNMP as fair or poor, and self-rated levels of preparation did not increase with level of training (p=.71). Thirty-eight percent of respondents reported having being threatened by a patient over the prescription of pain medication. CONCLUSION Residents in this setting found CNMP management to be difficult. They lacked confidence in managing CNMP and did not gain confidence over the course of training. Substantial opportunities exist for improving resident education in CNMP.

Abstract
OBJECTIVE Extramedical prescription pain reliever use has generated much public concern; however, little is known regarding its epidemiology in the general population. METHODS Using data from the annual National Survey on Drug Use and Health (2002 and 2003), we explored demographics, drug use history, and physical/mental problems associated with recent onset use (initiated in past 24 mo, n=1528) and persistent use (initiated more than 2 y and still using within a year of the assessment, n=4400) of prescription pain relievers when taken without a clinician's prescription or not as prescribed. RESULTS Adolescents and young adults were more likely to initiate extramedical use as compared with older individuals. African-Americans were approximately half as likely to initiate extramedical use as compared with whites (odds ratio, OR: 0.56, 95% confidence interval, CI: 0.45, 0.70). Hispanics who began using prescription pain relievers extramedically were more likely to persist as compared with whites (OR: 1.84, 95% CI: 1.52, 2.22). Reporting lifetime use of marijuana (adjusted odds ratio, aOR: 6.86, 95% CI: 5.86, 8.03), cocaine (aOR: 5.36, 95% CI: 4.53, 6.33), and heroin (aOR: 3.87, 95% CI: 2.51, 5.97) was associated with initiation of extramedical prescription pain reliever use. Adults with mental problems were twice as likely to be recent onset users as compared with those without these symptoms, holding constant potential confounders. DISCUSSION This study supplies data that can improve our understanding of factors associated with the extramedical use of prescription pain relievers among 2 distinct stages of use.

Abstract
OBJECTIVE To review the evidence on identifying and managing misuse of and dependence on opioids among primary care patients with chronic pain. QUALITY OF EVIDENCE MEDLINE was searched using such terms as "opioid misuse" and "addiction." The few studies on the prevalence of opioid dependence in primary care populations were based on retrospective chart reviews (level II evidence). Most recommendations regarding identification and management of opioid misuse in primary care are based on expert opinion (level III evidence). MAIN MESSAGE Physicians should ask all patients receiving opioid therapy about current, past, and family history of addiction. Physicians should take "universal precautions" that include careful prescribing and ongoing vigilance for signs of misuse. Patients suspected of opioid misuse can be treated with a time-limited trial of structured opioid therapy if they are not acquiring opioids from other sources. The trial should consist of daily to weekly dispensing, regular urine testing, and tapering of doses of opioids. If the trial fails or is not indicated, patients should be referred for methadone or buprenorphine treatment. CONCLUSION Misuse of and dependence on opioids can be identified and managed successfully in primary care.

Abstract
UNLABELLED Little is known about primary care physicians' (PCPs) prescribing of opioids. We describe trends and factors associated with opioid prescribing during PCP visits over the past decade. Using the National Ambulatory Medical Care Survey, we found an opioid prescribed in 2,206 (5%) PCP visits from 1992 to 2001. The prevalence of visits where an opioid was prescribed increased from a low of 41 per 1000 visits in 1992-1993 to a peak of 63 per 1000 in 1998-1999 (P < .0001 for trend) and then stabilized (59 per 1000 in 2000-2001). Several factors increased the odds of receiving an opioid: having Medicaid (odds ratio [OR] 2.09 [95% confidence interval (CI) 1.82-2.40]) or Medicare (OR 2.00 [95% CI 1.68-2.39]); having a visit between 15 and 35 minutes (OR 1.16 [95% CI 1.05-1.27]); and receiving an NSAID (OR 2.27 [95% CI 2.04-2.53]). Patients of hispanic (OR .67 [95% CI .56-.81]) or other race/ethnicity (OR .68 [95% CI .52-.90]), patients in health maintenance organizations (OR .74 [95% CI .66-.84]), and those living in the northeast (OR .60 [95% CI .51-.69]) or midwest (OR .75 [95% CI .66-.85]) had lower odds of receiving an opioid. Substantial variation exists in opioid prescribing by PCPs. Now that pain management standards are advocated, understanding the dynamics of opioid prescribing is necessary. PERSPECTIVE This study describes a decade-long increase in opioid prescribing by U.S. primary care physicians and identifies important geographic-, racial/ethnic-, and insurance-related differences in who receives these medications. Several underlying factors, including regulatory and legal pressures, attitudes and knowledge of opioids, and publicized opioid-related events, may contribute to these differences.

Abstract
BACKGROUND New Mexico has the highest rate of drug-induced mortality in the United States. The contribution of prescription drugs to the total overdose death rate has not been adequately described. METHODS A total of 1,906 unintentional drug overdose deaths occurring in 1994 to 2003 in New Mexico were analyzed. Unintentional drug overdose death was defined as death caused by prescription, illicit, or a combination of drugs, as determined by a pathologist. Deaths were investigated annually by the medical examiner and data were analyzed in 2004-2005. Rates and trends of total and prescription drug overdose death were calculated, decedent characteristics were analyzed, and common drug combinations causing death were described. RESULTS The rate of unintentional prescription drug overdose death increased by 179% (1.9 to 5.3/100,000) from 1994 to 2003. A high percentage of prescription drug overdose decedents were white non-Hispanic (63.2%) and female (43.9%). These decedents were older and less frequently had alcohol listed as an additional cause of death than decedents of other drug overdose categories. Of all deaths caused by prescription drug(s) (n =765), 590 (77.1%) were caused by opioid painkillers, 263 (34.4%) by tranquilizers, and 196 (25.6%) by antidepressants. CONCLUSIONS The rate of prescription drug overdose death in New Mexico increased significantly over the 10-year study period. Comprehensive surveillance of drug overdose deaths is recommended to describe their occurrence in the context of both medical and diverted use of prescription drugs. Understanding decedent profiles and the potential risk factors for prescription drug overdose death is crucial for effective drug overdose prevention education among healthcare providers.

Abstract
OBJECTIVES The aim of this study was to evaluate the effects of two successive neurotoxin treatments for chronic low back pain using multiple pain rating scales in an open-label, prospective study. METHODS Adult patients with chronic low back pain received multiple paraspinal muscle injections with a maximum dosing of 500 units of botulinum A toxin per session. Those with a beneficial clinical response received a second treatment at 4 months. Pain was assessed by visual analog scale (VAS), modified low back pain questionnaire (OLBPQ), and a clinical low back pain questionnaire (CLBPQ) at baseline, 3 weeks, 2 months, 4 months, and 6 months after the first treatment. RESULTS Eighteen women and 42 men, ages 21 to 79 years (mean 46.6 years), with low back pain of a mean duration of 9.1 years were included. Significant improvement in back and radicular pain occurred at 3 weeks in 60% and at 2 months in 58% of the cohort. Beneficial clinical response to the first injection predicted response to reinjection in 94%. A significant minority of patients had a sustained beneficial effect from the first injection at 4 (16.6%) and 6 months (8.3%). Two patients had a transient flu-like reaction after the initial treatment. CONCLUSIONS Botulinum toxin A improves refractory chronic low back pain with a low incidence of side effects. The beneficial clinical response is sustained with a second treatment.

Abstract
Background Opioid misuse can complicate chronic pain management, and the non-medical use of opioids is a growing public health problem. The incidence and risk factors for opioid misuse in patients with chronic pain, however, have not been well characterized. We conducted a prospective cohort study to determine the one-year incidence and predictors of opioid misuse among patients enrolled in a chronic pain disease management program within an academic internal medicine practice. Methods One-hundred and ninety-six opioid-treated patients with chronic, non-cancer pain of at least three months duration were monitored for opioid misuse at pre-defined intervals. Opioid misuse was defined as: 1. Negative urine toxicological screen (UTS) for prescribed opioids; 2. UTS positive for opioids or controlled substances not prescribed by our practice; 3. Evidence of procurement of opioids from multiple providers; 4. Diversion of opioids; 5. Prescription forgery; or 6. Stimulants (cocaine or amphetamines) on UTS. Results The mean patient age was 52 years, 55% were male, and 75% were white. Sixty-two of 196 (32%) patients committed opioid misuse. Detection of cocaine or amphetamines on UTS was the most common form of misuse (40.3% of misusers). In bivariate analysis, misusers were more likely than non-misusers to be younger (48 years vs 54 years, p < 0.001), male (59.6% vs. 38%; p = 0.023), have past alcohol abuse (44% vs 23%; p = 0.004), past cocaine abuse (68% vs 21%; p < 0.001), or have a previous drug or DUI conviction (40% vs 11%; p < 0.001%). In multivariate analyses, age, past cocaine abuse (OR, 4.3), drug or DUI conviction (OR, 2.6), and a past alcohol abuse (OR, 2.6) persisted as predictors of misuse. Race, income, education, depression score, disability score, pain score, and literacy were not associated with misuse. No relationship between pain scores and misuse emerged. Conclusion Opioid misuse occurred frequently in chronic pain patients in a pain management program within an academic primary care practice. Patients with a history of alcohol or cocaine abuse and alcohol or drug related convictions should be carefully evaluated and followed for signs of misuse if opioids are prescribed. Structured monitoring for opioid misuse can potentially ensure the appropriate use of opioids in chronic pain management and mitigate adverse public health effects of diversion.

Abstract
INTRODUCTION Opioid misuse is common among patients with chronic nonmalignant pain. There is a pressing need for physicians to increase their confidence and competence in managing these patients. METHODS A randomized controlled trial of family physicians (N = 88) attending 1 of 4 continuing medical education events helped to determine the effectiveness of e-mail case discussions in changing physician behavior. Before random assignment, participants completed a pretest and attended a 3-hour didactic session on prescribing opioids and benzodiazepines. The intervention group participated in 10 weeks of e-mail case discussions, with designated participants responding to questions on cases. An addictions physician facilitated the discussion. Several months after the e-mail discussion, participants took part in a mock telephone consultation; a blinded researcher posing as a medical colleague asked for advice about 2 cases involving opioid and benzodiazepine prescribing. Using a checklist, the researcher recorded the questions asked and advice given by the physician. RESULTS On post-testing, both groups expressed greater optimism about treatment outcomes and were more likely to report using a treatment contract and providing advice about sleep hygiene. There were no significant differences between pretesting and post-testing between the groups on the survey. During the telephone consultation, the intervention group asked significantly more questions and offered more advice than the control group (odds ratio for question items, 1.27 [p = .03]; advice items, 1.33 [p = .01). DISCUSSION Facilitated by electronic mail and a medical expert, case discussion is an effective means of improving physician performance. Telephone consultation holds promise as a method for evaluating physicians' assessment and management skills.

Abstract
Use of opioids for chronic non-cancer pain is increasing, but the clinical epidemiology and standards of care for this practice are poorly defined. Psychiatric disorders are associated with increased physical symptoms and may be associated with opioid use. We performed a secondary analysis of cross-sectional data from the Health Care for Communities (HCC) survey conducted in 1997-1998 (N=9279) to determine the association of psychiatric disorders and self-reported regular use of prescribed opioids within the past year. Regular prescription opioid use was reported by 282 (3%) respondents. In unadjusted logistic regression models, respondents with common mental disorders in the past year (major depression, dysthymia, generalized anxiety disorder, or panic disorder) were more likely to report regular prescription opioid use than those without any of these disorders (OR=6.15, 95% CI=4.13, 9.14, P< 0.001). Respondents reporting problem drug use (OR=4.75, 95% CI=2.52, 8.94, P<0.001), or problem alcohol use (OR=1.89, 95% CI=1.03, 3.40, P=.041) reported higher rates of prescribed opioid use than those without problem use. In multivariate logistic regression models controlling for demographic and clinical variables, the presence of a common mental disorder remained a significant predictor of prescription opioid use (OR=3.15, 95% CI=1.69, 5.88, P<0.001), among individuals reporting low pain interference (N=8307); but not (OR=1.27, n.s.) among those reporting high pain interference (N=972). Depressive, anxiety and drug abuse disorders are associated with increased use of regular opioids in the general population. Depressive and anxiety disorders are more common and more strongly associated with prescribed opioid use than drug abuse disorders.

Abstract
Background Chronic non-cancer pain is a common problem that is often accompanied by psychiatric comorbidity and disability. The effectiveness of a multi-disciplinary pain management program was tested in a 3 month before and after trial. Methods Providers in an academic general medicine clinic referred patients with chronic non-cancer pain for participation in a program that combined the skills of internists, clinical pharmacists, and a psychiatrist. Patients were either receiving opioids or being considered for opioid therapy. The intervention consisted of structured clinical assessments, monthly follow-up, pain contracts, medication titration, and psychiatric consultation. Pain, mood, and function were assessed at baseline and 3 months using the Brief Pain Inventory (BPI), the Center for Epidemiological Studies-Depression Scale scale (CESD) and the Pain Disability Index (PDI). Patients were monitored for substance misuse. Results Eighty-five patients were enrolled. Mean age was 51 years, 60% were male, 78% were Caucasian, and 93% were receiving opioids. Baseline average pain was 6.5 on an 11 point scale. The average CESD score was 24.0, and the mean PDI score was 47.0. Sixty-three patients (73%) completed 3 month follow-up. Fifteen withdrew from the program after identification of substance misuse. Among those completing 3 month follow-up, the average pain score improved to 5.5 (p = 0.003). The mean PDI score improved to 39.3 (p < 0.001). Mean CESD score was reduced to 18.0 (p < 0.001), and the proportion of depressed patients fell from 79% to 54% (p = 0.003). Substance misuse was identified in 27 patients (32%). Conclusions A primary care disease management program improved pain, depression, and disability scores over three months in a cohort of opioid-treated patients with chronic non-cancer pain. Substance misuse and depression were common, and many patients who had substance misuse identified left the program when they were no longer prescribed opioids. Effective care of patients with chronic pain should include rigorous assessment and treatment of these comorbid disorders and intensive efforts to insure follow up.

Abstract
OBJECTIVE Concerns regarding the efficacy, toxicity, tolerance, dependence, and abuse of opioids have limited their use for patients with chronic spine pain. In our previous study of rheumatology clinic patients, opioid analgesics were found to be highly effective, produced only mild side effects, and had few instances of opioid abuse. The purpose of this study was to replicate our previous study in another large cohort of patients with nonmalignant pain due to well-defined spinal diseases. METHODS Opioid use was studied in 230 orthopedics spine clinic patients by retrospective analysis of prescriptions for 3 years and cross-sectional analysis of efficacy and toxicity by patient interviews. Opioid use and stability of the daily dose over 3 years were derived from computerized pharmacy records. Medical records, operative reports, and radiographic studies were reviewed to determine the reason for dosage escalations and to detect instances of abuse or addiction behaviors. Patients were interviewed to determine the efficacy, frequency, and types of side effects and instances of obtaining opioids from sources outside the Veterans Affairs system. RESULTS Opioids were prescribed for 152 of the 230 patients, for < 3 months (short-term [STO]) in 94, > or =3 months (long-term [LTO]) in 58, and none in 72 (no opioid [NTO]). Medications prescribed were codeine, oxycodone, propoxyphene, tramadol, morphine, meperidine, fentanyl, or hydroxycodone, either alone or in combination. Interviews were completed in 72 STO, 50 LTO, and 45 NTO patients. Pain severity (0-10 scale) was not different in patients with different spinal pathologies. Opioids significantly reduced the back pain severity score from 8.3 +/- 1.5 to 4.5 +/- 2.2 (mean +/- SD). Mild side effects (most commonly, constipation and sedation) were reported by 58% of the opioid-treated patients but rarely caused them to stop taking the medication. There was no significant increase from the mean +/- SD initial opioid dosage of 5.0 +/- 12.2 30-mg codeine equivalents per day (30 mg oral codeine = 5 mg oral morphine) to the mean peak dosage of 7.9 +/- 12.5 and the mean recent dosage of 4.3 +/- 6.3, suggesting that tolerance to opioid analgesia did not appear to occur in these patients. Dosage escalations of > 2 30-mg codeine equivalents occurred 19 times in 17 LTO patients and was due to worsening of the underlying painful condition, complications of spine surgery, or unrelated surgical or medical problems in all but 3 of them (5%). These 3 patients also displayed other abuse behaviors. Abuse behaviors were not more frequent in those with or without a history of abuse/addiction. CONCLUSION This study provides data on the efficacy, toxicity, tolerance, and abuse or addiction behaviors with opioid therapy in a large cohort of patients in an orthopedics spine clinic. The results provide objective data from patients with well-defined spine diagnoses to challenge the position that opioid treatment is inappropriate for chronic nonmalignant pain. This study provides clinical evidence to support and protect physicians treating patients with chronic musculoskeletal diseases, who may be reluctant to prescribe opioids because of possible sanctions from regulatory agencies. More important, it will benefit patients by permitting them to receive these effective, safe medications.

Abstract
OBJECTIVE To provide medication price data and cost-reducing strategies for the acute treatment of migraine. METHODS Retail prices for common acute care medications were found at http://www.drugstore.com. Cost-reduction tactics were obtained from literature searches and clinical experience. RESULTS Several strategies can reduce cost without sacrificing treatment outcome. In mild to moderate migraine, low-priced nonsteroidal anti-inflammatory drugs can be used as first-line medications due to their proven efficacy and favorable tolerability. For patients with more severe migraine, implementing a stratified care approach-using migraine-specific medications early in acute treatment-is cost-effective for most patients. Stratified care not only improves outcome and decreases disability, but also reduces cost. Pill splitting and early administration of triptans within an attack enhance their value. Supplying rescue medications, such as opioids, sedatives, and phenothiazines, can prevent emergency department visits. Minimizing multiple dosing of triptans and reducing utilization of expensive health care resources are key factors in reducing the cost of effective migraine treatment. An important affordability factor for patients with co-payments is the number of triptan pills per package. Sumatriptan, naratriptan, and frovatriptan each contain 9 tablets per package, while most other triptan packages contain 6. Current triptan retail prices (per unit) include: Amerge 1 and 2.5 mg, 17.78 dollars; Axert 6.25 and 12.5 mg, 16.31 dollars; Frova 2.5 mg, 13.89 dollars; Imitrex 50 mg, 14.96 dollars; Imitrex 100 mg, 14.41 dollars; Imitrex Nasal Spray 20 mg, 21.61 dollars; Imitrex SQ 6 mg, 50.26 dollars; Maxalt 5 and 10 mg, 15 dollars; Maxalt-MLT 5 and 10 mg, 15 dollars; Relpax 40 mg, 13.58 dollars; Zomig 2.5 mg, 13.67 dollars; Zomig 5 mg, 15.89 dollars; Zomig-ZMT 2.5 mg, 13.67 dollars; and Zomig-ZMT 5 mg, 15.89 dollars. CONCLUSIONS Practitioners can optimize the use of health care dollars without compromising quality of care through awareness of cost-saving treatment strategies, as well as price variations among medications.

Abstract
To characterize prescription opioid dependent patients in a methadone maintenance treatment (MMT) program, a detailed retrospective chart review of new admissions (1997-1999, n=178, mean age=34.5+/-0.7 years, 65% male) was conducted. At admission most patients (83%) had been using prescription opioids (+/-heroin). Four groups were identified: 24% had used prescription opioids only; 24% used prescription opioids initially and heroin later; 35% used heroin first and prescription opioids subsequently; and 17% had used heroin only (this group was significantly younger: mean age 26+/-1 years, P=0.0001). Subjects reported regular use of prescription opioids at higher than therapeutic dosages. For example, in the 'prescription opioid only' group the reported mean (+/-S.E.) number of codeine or oxycodone-containing tablets consumed daily was 23 (+/-6) tablets and 21 (+/-3) tablets, respectively. There were no significant differences found amongst the groups in measures of social stability. Those dependent on prescription opioids alone were less likely to use illicit non-opioid drugs or to be associated with injection drug use. Those that used prescription opioids only or initially were more likely to have ongoing pain problems and to be involved in psychiatric treatment. Further research is required to better elucidate the complex relationships between pain, mental health and addiction in order to develop optimal prevention and treatment strategies for prescription opioid dependence.

Abstract
The evaluation of the complex chronic pain patient should be different than for the patient with a simple pain problem. The former requires a team approach. It is important that the neurosurgeon contemplating a pain-relieving operation get the best information that is likely to have an impact on outcome. This should include the following: 1. Some way to extract the appropriate information contained in the patient's medical records. 2. Physical factors that have a negative impact on prognosis. 3. Psychologic information, including return-to-work decisions, medication use issues, meaning of prior successes, negative environmental factors, codependency issues, secondary gains and their impact, presence of pain games, negatively acting financial considerations, impact of depression, presence of poor role models, impact of pain on general functioning, and the patient's future plans. Consider that just like a successful operation is a symphony of relatively simple harmonious parts, so, too, is the assessment of the complex chronic pain patient. The complexity of the patient and her or his predicament should not impair your ability to understand her or his real needs. The appropriate assessment of the patient requires that issues other than the pain itself be factored into the decisions about interventions. In the end, it is not appropriate to suggest afterward that psychosocial factors were the major cause for a poor result when nothing had been done about the same factors that had been present before the procedure.
