RESUMO
Background: Urine drug testing techniques have different rates of false-positive and false-negative test results. However, clinicians may have highly varying perceptions of test accuracy and may compensate for perceived inaccuracy by incorporating other factors into their interpretation of observed test results. Thus, there is the potential for adverse consequences from decisions based on inaccurate test results or interpretation. Methods: We surveyed 466 members of the American Society of Addiction Medicine to examine clinicians' perceptions of the accuracy of 2 types of urine drug tests, immunoassay (IA) and liquid chromatography-tandem mass spectrometry (LC-MS/MS), and the extent to which behavioral and demographic factors influence the interpretation of test results. Participants read 4 brief vignettes describing positive and negative test results in hypothetical patients who differed along several dimensions (gender, age, race/ethnicity, comorbid mental disorder, court-ordered versus voluntary status, treatment compliance). Outcome variables include likelihood of renewed drug use, likelihood of test error, whether to request additional testing, and whether to report the violation to a probation officer. Results: The strongest predictor of study outcomes was treatment compliance (consistent versus inconsistent attendance), as this was the only independent variable to generate effect sizes of medium strength. Significant effect sizes were also found for type of test used (IA versus LC-MS/MS), legal status (court-mandated versus voluntary), presence of a comorbid mental disorder, treatment history, and race, although effect sizes for these variables were small and less consistently observed. Conclusions: These results highlight the potential for error in clinician judgments about urine drug testing. Not only were participants likely to underestimate the accuracy of "confirmatory" LC-MS/MS testing, but vignettes suggested that a number of historical and demographic factors may influence interpretation of test results.

ABSTRACTObjective:Sleep can affect quality of life (QoL) during cancer survivorship, and symptoms related to poor sleep can be exacerbated. We examined the prevalence, severity, and nature of subjective sleep complaints in women surviving stage I-III breast cancer who were 1-10 years posttreatment. We also examined the demographic, medical, physical, and psychosocial correlates of poor sleep in these women in order to identify the subgroups that may be most in need of intervention. METHOD: A total of 200 patients at a comprehensive cancer center who were 1-10 years posttreatment for primary stage I-III breast cancer with no evidence of disease at the time of enrollment completed a battery of questionnaires on demographics, sleep, physical symptoms, mood, cancer-specific fears, and QoL. RESULTS: The women had a mean age of 57 years (SD = 10.0), with a mean of 63.3 months (SD = 28.8) of post-cancer treatment. Some 38% of these patients were identified as having poor-quality sleep. Women with poor sleep took longer to fall asleep, had more awakenings, and acquired 2 hours less sleep per night than those with good sleep. They also had a lower QoL, greater severity of pain, more concerns about health and recurrence, and increased vasomotor symptoms (p < 0.05). Daytime sleepiness and depression were found to be not significantly correlated with sleep quality. SIGNIFICANCE OF RESULTS: Many breast cancer survivors had severe subjective insomnia, and several breast cancer survivor subgroups were identified as having members who might be most in need of sleep-improvement interventions. Addressing physical symptoms (e.g., vasomotor symptoms and pain) and providing education about the behavioral, social, environmental, and medical factors that affect sleep could result in substantial improvement in the life course of breast cancer survivors.

OBJECTIVE: To conduct an Internet patient survey through the National Fibromyalgia & Chronic Pain Association on reactions to the first 100 days following the rescheduling of hydrocodone. METHODS: Face-valid survey questions were created with expert consensus along with repurposed questions used on previous NFMCPA surveys covering domains such as demographics and symptoms. The questionnaire was designed to be administered over the Internet. RESULTS: 6,420 responders met screening criteria and completed the survey. Most (5,181, or 82.5%) had been prescribed hydrocodone for more than 1 year. 2,296, (39.0%) reported no changes in access to hydrocodone, while the majority experienced some barriers. Of those who could no longer get hydrocodone, 1,067 (18.1%) borrowed pain medications, 1,007 (17.1%) turned to marijuana, 773 (13.1%) used alcohol, and 135 (2.3%) used illicit drugs. Most respondents had to visit their healthcare providers more often (N = 3,699, 64.2%) and 1,735 (30.3%) reported some type of issue interacting with their pharmacy. Most felt that the rescheduling was neither a fair nor appropriate solution to the abuse of hydrocodone (N = 4,938, 88.3%). For those still working, 801 (46.2%) reported that they had missed work because of the stricter regulations. 1,462 (27.2%) reported having thoughts of suicide since the rescheduling. SIGNIFICANCE: The unintended consequences for people with chronic pain that have been caused by the rescheduling effort to impede hydrocodone abuse are negatively impacting thousands. These consequences include suffering from being placed on less effective drugs, increased cost, inconvenience, and negative influence on physician-patient and pharmacist-patient relationships.

OBJECTIVE: Evaluate aberrant drug-related behaviors in patients administering fentanyl buccal tablet or traditional short-acting opioids for breakthrough pain. DESIGN: Twelve-week open-label extension. SETTING: Forty-two US sites. SUBJECTS: Opioid-tolerant patients with chronic pain who completed the previous randomized, double-blind, crossover portion of a study comparing fentanyl buccal tablet and immediate-release oxycodone for treatment of breakthrough pain. METHODS: Patients were rerandomized to continue treatment with fentanyl buccal tablet or begin any traditional short-acting opioid. Assessments included Screener and Opioid Assessment for Patients with Pain-Revised (SOAPP-R) at baseline and Addiction Behaviors Checklist and Current Opioid Misuse Measure at baseline and final visit. Case report forms were reviewed retrospectively to identify aberrant drug-related behaviors. RESULTS: One hundred thirty patients entered the open-label extension (fentanyl buccal tablet, N = 65; traditional short-acting opioid, N = 65). SOAPP-R scores were <18 (low risk of aberrant drug-related behavior) in 74% of patients; no significant differences in SOAPP-R scores were observed between treatment groups. At the final visit, ≤14% of patients in each treatment group had scores indicating potential aberrant drug-related behavior (Addiction Behaviors Checklist ≥3, Current Opioid Misuse Measure ≥9); no significant differences in scores were observed between treatment groups. Baseline SOAPP-R score ≥18 was not predictive of Addiction Behaviors Checklist ≥3 but was predictive of Current Opioid Misuse Measure ≥9. Aberrant behaviors were identified in 12 (18%) fentanyl buccal tablet patients and 13 (20%) traditional short-acting opioid patients. CONCLUSIONS: Incidence of aberrant drug-related behaviors was similar between patients taking fentanyl buccal tablet and traditional short-acting opioids over 12 weeks.

OBJECTIVE: The long-term effects of disease and treatment in colorectal cancer (CRC) survivors are poorly understood. This study examined the prevalence and characteristics of pain in a sample of CRC survivors up to 10 years post-treatment. DESIGN: One hundred cancer-free CRC survivors were randomly chosen from an institutional database and completed a telephone survey using the Brief Pain Inventory, Neuropathic Pain Questionnaire-Short Form, Quality of Life Cancer Survivor Summary, Brief Zung Self-Rating Depression Scale, Zung Self-Rating Anxiety Scale, and Fear of Recurrence Questionnaire. RESULTS: Participants were primarily Caucasian (90%) married (69%) males (53.5%) with a mean age of 64.7 years. Chronic pain was reported in 23% of CRC survivors, with a mean moderate intensity rating (mean = 6.05, standard deviation = 2.66) on a 0-10 rating scale. Over one-third (39%) of those with pain attributed it to their cancer or treatment. Chi-square and t-test analyses showed that survivors with pain were more likely to be female, have lower income, be more depressed and more anxious, and show a higher endorsement of suicidal ideation than CRC survivors without chronic pain. On average, pain moderately interfered with daily activity. CONCLUSIONS: Chronic pain is likely a burdensome problem for a small but not inconsequential minority of CRC survivors requiring a biopsychosocial treatment approach to improve recognition and treatment. Open dialogue between clinicians and survivors about physical and emotional symptoms in long-term follow-up is highly recommended.

Recurrent use of prescription opioid analgesics by chronic pain patients may result in opioid dependence, which involves implicit neurocognitive operations that organize and impel craving states and compulsive drug taking behavior. Prior studies have identified an attentional bias (AB) towards heroin among heroin dependent individuals. The aim of this study was to determine whether opioid-dependent chronic pain patients exhibit an AB towards prescription opioid-related cues. Opioid-dependent chronic pain patients (n = 32) and a comparison group of non-dependent opioid users with chronic pain (n = 33) completed a dot probe task designed to measure opioid AB. Participants also rated their opioid craving and self-reported arousal associated with opioid-related and neutral images, pain severity, and relief from pain treatments. Repeated-measures ANOVA revealed a significant group (opioid-dependent vs. non-dependent opioid user) × presentation duration (200. vs. 2,000 ms.) interaction, such that opioid-dependent individuals evidenced a significant AB towards opioid cues presented for 200 ms but not for cues presented for 2,000 ms, whereas non-dependent opioid users did not exhibit a significant mean AB at either stimulus duration. Among opioid-dependent individuals, 200 ms opioid AB was significantly associated with opioid craving, while among non-dependent opioid users, 200 ms opioid AB was significantly associated with relief from pain treatments. Furthermore, dependent and non-dependent opioid users experienced opioid cues as significantly more arousing than neutral cues. Opioid dependence among chronic pain patients appears to involve an automatic AB towards opioid-related cues. When coupled with chronic pain, attentional fixation on opioid cues may promote compulsive drug use and addictive behavior.

The standard of care calls for the assessment of patients with chronic pain prior to the initiation of opioids, with one part of this assessment including assessment of the risk of misuse of medications. However, traditional opioid risk assessment tools focus almost entirely on individual factors and on the risk of misuse and addiction to opioids. Diversion of opioid medications has been found to be not uncommon, but to date, there have been no assessment tools specifically designed to assess the risk of diversion. In this study, we developed a measure designed specifically to assess the risk of an opioid medication ending up in the hands of someone other than the chronic pain patient to whom they were prescribed. A 15-item measure, the Diversion Risk Scale, was created and administered to 85 patients at a chronic pain practice. Results found that the measure had acceptable predictive validity. It was moderately correlated with traditional opioid risk assessment tools and showed improved ability to predict specific indicators of diversion. Diversion has been an understudied phenomenon, and the clinical value of an assessment tool that can help predict diversion in the chronic pain population is discussed.

Importance: The direct addition of buprenorphine to urine drug test specimens to mimic results suggestive of adherence is a clinically significant result, yet little is known about the phenomenon. Objective: To characterize factors associated with the direct addition of buprenorphine to urine specimens among patients prescribed buprenorphine for opioid use disorder. Design, Setting, and Participants: This cross-sectional study of urine drug test specimens was conducted from January 1, 2017, to April 30, 2022, using a national database of urine drug test specimens ordered by clinicians from primary care, behavioral health, and substance use disorder treatment clinics. Urine specimens with quantitative norbuprenorphine and buprenorphine concentrations from patients with opioid use disorder currently prescribed buprenorphine were analyzed. Exposures: Nonprescribed opioid or stimulant co-positive, clinical setting, collection year, census division, patient age, patient sex, and payor. Main Outcomes and Measures: Norbuprenorphine to buprenorphine ratio less than 0.02 identified direct addition of buprenorphine. Unadjusted trends in co-positivity for stimulants and opioids were compared between specimens consistent with the direct addition of buprenorphine. Factors associated with the direct addition of buprenorphine were examined with generalized estimating equations. Results: This study included 507â¯735 urine specimens from 58â¯476 patients. Of all specimens, 261â¯210 (51.4%) were obtained from male individuals, and 137â¯254 (37.7%) were from patients aged 25 to 34 years. Overall, 9546 (1.9%) specimens from 4550 (7.6%) patients were suggestive of the direct addition of buprenorphine. The annual prevalence decreased from 2.4% in 2017 to 1.2% in 2020. Opioid-positive with (adjusted odds ratio [aOR], 2.01; 95% CI, 1.85-2.18) and without (aOR, 2.02; 95% CI, 1.81-2.26) stimulant-positive specimens were associated with the direct addition of buprenorphine to specimens, while opioid-negative/stimulant-positive specimens were negatively associated (aOR, 0.78; 95% CI, 0.71-0.85). Specimens from patients aged 35 to 44 years (aOR, 1.59; 95% CI, 1.34-1.90) and primary care (aOR, 1.60; 95% CI, 1.44-1.79) were associated with the direct addition of buprenorphine. Differences by treatment setting decreased over time. Specimens from the South Atlantic census region had the highest association (aOR, 1.4; 95% CI, 1.25-1.56) and New England had the lowest association (aOR, 0.54; 95% CI, 0.46-0.65) with the direct addition of buprenorphine. Conclusions and Relevance: In this cross-sectional study, the direct addition of buprenorphine to urine specimens was associated with other opioid positivity and being collected in primary care settings. The direct addition of buprenorphine to urine specimens is a clinically significant finding, and best practices specific for this phenomenon are needed.

For many cancer survivors, disease-related long-term morbidities and the application of advanced cancer treatments have resulted in the development of a chronic pain state. This brief review explores the relationship between what is known about the treatment of active cancer pain syndromes-both continuous pain and breakthrough pain-and persisting pain syndromes in cancer survivors. We also posit that because there is evidence to suggest that poorly treated acute pain can lead to protracted pain conditions, acute pain should be recognized and treated promptly, both for short- and long-term gain. In the short term, better acute pain treatment can improve functionality and psychological well-being, whereas in the long term, mounting evidence suggests that it could prevent of future chronic pain.

OBJECTIVE: Several prominent guidelines recommend that patients on long-term opioid therapy have periodic urine drug monitoring (UDM) for appropriate use; however, none address the specific questions of which patients to test, which substances to test for, how often to test, and how to act on the results. DESIGN: In the absence of adequate scientific evidence in the literature, a panel of experts in the field of pain and addiction medicine was convened to develop consensus UDM recommendations. The panel met three times between March 2010 and April 2011, and reviewed several drafts of the recommendations document between meetings. RESULTS: The group was able to achieve consensus on a set of UDM recommendations addressing test selection, test frequency, interpretation of results, and how to handle discrepancies based on specific results. CONCLUSION: While the participating panel members recognize that there currently is a limited evidence base to support the expert panel's recommendations, primary care providers and pain specialists are largely acting today based on anecdote, intuition, and individual experience. The recommendations are meant to begin to provide a framework for standardizing practices for UDM in the treatment of chronic pain, and to serve as a catalyst to advance research that quantifies the effects of UDM on opioid therapy management and patient outcomes.

OBJECTIVE: Clinicians and policymakers have been wrestling with the appropriateness and safety of opioid therapy during the opioid crisis. Policy and clinical decisions have often been made without much current data on trends in drug use in patients with pain. Thus, we evaluated definitive urine drug test (UDT) results in patients being treated for pain to see if those taking their prescribed opioids were less likely to be positive for the primary illicit drugs currently driving overdose deaths: cocaine, heroin, fentanyl, and methamphetamine. DESIGN, SETTING, AND PATIENTS: A cross-sectional study of UDT results from January 1, 2015 to September 30, 2021, from 600,000 patient specimens submitted for testing by pain management specialists. INTERVENTIONS: UDT by liquid chromatography-tandem mass spectrometry as ordered by the treating clinician. MAIN OUTCOME MEASURES: Presence of other substances stratified by whether a patient's prescribed opioid was found. RESULTS: The presence of cocaine, heroin, fentanyl, and methamphetamine for the total population was low (<5 percent). Of the 347,092 patients prescribed opioids, 76 percent (n = 264,961) were positive on UDT for their prescribed opioid ("consistent"). Compared to patients without their prescribed opioid present ("inconsistent"), patients consistent with therapy were 54 percent (incidence rate ratio (IRR) 1.54, 95 percent confidence interval (CI) 1.47-1.59) less likely to be positive for cocaine, 47 percent [IRR 1.47, 95 percent CI 1.34-1.57] less likely to be positive for heroin, and 35 percent [IRR 1.35, 95 percent CI 1.24-1.45] less likely to be positive for methamphetamine, p < 0.001. Differences between the groups for fentanyl were not significant. CONCLUSIONS: Overall positivity rates for cocaine, heroin, fentanyl, and methamphetamine were low. Patients with prescribed opioid present were less likely to be positive for cocaine, heroin, or methamphetamine. Patterns of substance use within this pain management population should be used to inform ongoing policy decisions.

Importance: Drug overdose deaths in the US are currently the highest ever recorded; data collected from public health surveillance sources can help to identify emerging drug use patterns associated with overdose mortality rates, but the time lag in results often limits utility. Urine drug testing (UDT) is one potentially underused source that could augment surveillance efforts through timely data collection. Objective: To evaluate the correlation between real-time UDT results from a proprietary national database and overdose mortality data from the National Vital Statistics System. Design, Setting, and Participants: This retrospective cross-sectional study included 500 000 urine specimens submitted for UDT by substance use disorder (SUD) treatment health care practices and collected between January 1, 2013, and December 31, 2020. Real-time UDT data were obtained from the Millennium Health proprietary national database, and overdose mortality data were obtained from the National Vital Statistics System of the Centers for Disease Control and Prevention (CDC WONDER). Specimens were analyzed for specific drugs in 5 categories (cocaine, heroin, methamphetamine, synthetic opioids, and other opioids) using liquid chromatography-tandem mass spectrometry. Participants were adults aged 18 years and older who provided urine specimens at SUD treatment practices. Exposures: Urine drug testing. Main Outcomes and Measures: The primary outcome was the correlation between UDT positivity rates and overdose mortality rates at national, state, and county levels. Univariate and multivariate regression models were also used to evaluate the association between state- and county-level overdose mortality and standardized UDT positivity rates. Results: Among 500â¯000 unique patient specimens collected from SUD treatment practices between 2013 and 2020, 288 534 specimens (57.7%) were from men, and the median age of the study population was 34 years (IQR, 17-51 years). On a national level, synthetic opioids and methamphetamine were highly correlated with overdose mortality (Spearman ρ = 0.96 for both). When synthetic opioids were coinvolved, methamphetamine (ρ = 0.98), heroin (ρ = 0.78), cocaine (ρ = 0.94), and other opioids (ρ = 0.83) were also highly correlated with overdose mortality. In the absence of synthetic opioids, all drug categories were highly correlated (ρ = 0.75 for other opioids, 0.81 for heroin, and 0.88 for methamphetamine), with the exception of cocaine (ρ = -0.37). Synthetic opioids (ρ = 0.77) and methamphetamine (ρ = 0.80) had the strongest state-level correlations over time, whereas other opioids had the lowest correlation for both total positivity (ρ = 0.31) and positivity in the absence of synthetic opioids (ρ = 0.23). In Ohio, county-level correlation was strongest for synthetic opioids (ρ = 0.71), followed by heroin (ρ = 0.69) and methamphetamine (ρ = 0.67). At the state level, the multivariate incidence rate ratio (IRR) for synthetic opioids was 1.16 (95% CI, 1.14-1.19; P < .001), and at the county level, the IRR was 1.13 (95% CI, 1.09-1.17; P < .001), suggesting that for every 1-SD increase in the UDT positivity rate, there were 16.2% and 12.8% increases, respectively, in monthly overdose deaths. Both methamphetamine (11.7% increase per 1-SD increase in UDT positivity rate; IRR, 1.12; 95% CI, 1.09-1.14; P < .001) and cocaine (5.1% increase per 1-SD increase in UDT positivity rate; IRR, 1.05; 95% CI, 1.03-1.07; P < .001) also had significant positive associations with mortality rates, but the effect sizes were smaller than that of synthetic opioids (IRR, 1.16). Conclusions and Relevance: In this study, UDT results were highly correlated with mortality rates at national, state, and county levels. These findings suggest that real-time UDT surveillance can help to quickly identify changes in drug use patterns that might inform targeted harm reduction strategies designed to prevent overdose deaths.

OBJECTIVE: The Cancer Behavior Inventory-Brief Version (CBI-B), a 12-item measure of self-efficacy for coping with cancer derived from the longer 33-item version, was subjected to psychometric analysis. METHOD: Participants consisted of three samples: 735 cancer patients from a multicenter CCOP study, 199 from central Indiana, and 370 from a national sample. Samples were mixed with respect to initial cancer diagnosis. Participants completed the CBI-B and measures of quality of life, optimism, life satisfaction, depression, and sickness impact. RESULTS: Exploratory Factor Analysis with oblique rotation yielded four factors in the first sample: (1) Maintaining Independence and Positive Attitude; (2) Participating in Medical Care; (3) Coping and Stress Management; and (4) Managing Affect, which were confirmed in subsequent samples. Cronbach α coefficient for the 12-item CBI-B ranged from 0.84 to 0.88. Validity of the CBI-B was demonstrated by positive correlations with measures of quality of life and optimism, and negative correlations with measures of depression and sickness impact. CONCLUSION: The CBI-B is a valid brief measure of self-efficacy for coping that could be easily integrated into clinical oncology research and practice, and also used in screening patients.

Opioid-related deaths in the United States have become a public health problem, with accidental and unintended overdoses being especially troubling. Screening for psychological risk factors is an important first step in safeguarding against nonadherence practices and identifying patients who may be vulnerable to the risks associated with opioid therapy. Validated screening instruments can aid in this attempt as a complementary tool to clinicians' assessments. A structured screening is imperative as part of an assessment, as clinician judgment is not the most reliable method of identifying nonadherence. As a complement to formal screening, we present for discussion and possible future study certain psychological variables observed during years of clinical practice that may be linked to medication nonadherence and accidental overdose. These variables include catastrophizing, fear, impulsivity, attention deficit disorders, existential distress, and certain personality disorders. In our experience, chronic pain patients with dual diagnoses may become "chemical copers" as a way of coping with their negative emotion. For these patients, times of stress could lead to accidental overdose. Behavioral, cognitive-behavioral (acceptance and commitment, dialectical behavior), existential (meaning-centered, dignity), and psychotropic therapies have been effective in treating these high-risk comorbidities, while managing expectations of pain relief appears key to preventing accidental overdose.

OBJECTIVE: A panel of experts in pain medicine and public policy convened to examine root causes and risk factors for opioid-related poisoning deaths and to propose recommendations to reduce death rates. METHODS: Panelists reviewed results from a search of PubMed and state and federal government sources to assess frequency, demographics, and risk factors for opioid-related overdose deaths over the past decade. They also reviewed results from a Utah Department of Health study and a summary of malpractice lawsuits involving opioid-related deaths. RESULTS: National data demonstrate a pattern of increasing opioid-related overdose deaths beginning in the early 2000s. A high proportion of methadone-related deaths was noted. Although methadone represented less than 5% of opioid prescriptions dispensed, one third of opioid-related deaths nationwide implicated methadone. Root causes identified by the panel were physician error due to knowledge deficits, patient non-adherence to the prescribed medication regimen, unanticipated medical and mental health comorbidities, including substance use disorders, and payer policies that mandate methadone as first-line therapy. Other likely contributors to all opioid-related deaths were the presence of additional central nervous system-depressant drugs (e.g., alcohol, benzodiazepines, and antidepressants) and sleep-disordered breathing. CONCLUSIONS: Causes of opioid-related deaths are multifactorial, so solutions must address prescriber behaviors, patient contributory factors, nonmedical use patterns, and systemic failures. Clinical strategies to reduce opioid-related mortality should be empirically tested, should not reduce access to needed therapies, should address risk from methadone as well as other opioids, and should be incorporated into any risk evaluation and mitigation strategies enacted by regulators.

As opioid prescribing has dramatically expanded over the past decade, so too has the problem of prescription drug abuse. In response to these now two major public health problems - the problem of poorly treated chronic pain and the problem of opioid abuse - a new paradigm has arisen in pain management, namely risk stratification. Once a prescriber has determined that opioids will be used (a medical decision based on how intense the pain is, what has been tried and failed and, to some extent, what type of pain the patient has), he/she must then decide how opioid therapy is to be delivered. Different models of delivery of opioid therapy can be utilized, beginning the process with a risk assessment that is highly individualized to each patient. Recently, researchers have produced a wide variety of literature regarding assessment tools to be used for this purpose. And while there remains a need for larger prospective studies to examine the ability of each tool to predict aberrant drug-taking behaviors, clinicians can and should utilize one or more of these screening tools and understand their benefits and limitations. This chapter will describe the nature of current screening assessments, their potential for use in the pain population in various settings, past clinical observations and suggestions for moving forward.

Cancer-related cognitive dysfunction is an important issue for breast cancer survivors. Previous research has identified both cross-sectional and longitudinal alterations in brain function related to cancer status and treatment. In this study, we prospectively collected functional magnetic resonance imaging data in breast cancer cases treated with adjuvant chemotherapy and in controls with no cancer history during a working memory task. Data and blood specimens were collected immediately prior to the start of treatment (baseline) and following completion of treatment (follow-up), and at yoked intervals for controls. In secondary analysis we assessed the levels of oxidative DNA damage in peripheral blood lymphocytes of cases and controls using the Comet assay. A significant group*time interaction revealed reduced deactivation in the superior frontal gyrus in the controls at follow-up, in contrast to cases, who exhibited similar magnitude of deactivation at baseline and follow-up. Working memory performance indicated a significant improvement in the controls at follow-up, and no change in performance in cases. In secondary analyses, oxidative DNA damage levels were elevated in the cases at follow-up compared to controls, but no associations were found between the Comet assay variables and functional imaging at either time-point or group. In light of previous reports on task induced deactivations, our findings reflect continuing effortful processing at follow-up in the breast cancer group, with relatively less effortful processing in the control group given the reduced novelty and practice effects from the baseline to follow-up.

BACKGROUND: Opioids can be a safe and effective option for carefully selected patients with a structured treatment program that includes consistent monitoring. However, the benefits and risks of opioid therapy for patients with chronic pain, and society as a whole, have been sharply debated. A key component of this debate has involved the administration of rapid-onset opioids for the management of breakthrough pain. OBJECTIVE: Review key aspects of breakthrough pain management with fentanyl buccal tablet, with a focus on minimizing risk to optimize therapeutic outcomes. Recommendations that apply broadly to all rapid-onset opioids are also discussed. DESIGN: Available fentanyl buccal tablet clinical and post-marketing data were reviewed. RESULTS: Like other schedule II controlled substances, and because fentanyl buccal tablet is a highly potent opioid, its use is associated with risk of overdose, misuse, and diversion. As with all rapid-onset opioids, particular attention to patient selection and risk assessment is warranted. The inclusion and exclusion criteria in fentanyl buccal tablet clinical studies represent patient selection standards that should be translated to clinical practice, most importantly, that patients are opioid-tolerant before fentanyl buccal tablet initiation. Titration of fentanyl buccal tablet from a low starting dose to a successful dose allows the safe identification of a dose that provides the greatest pain relief without unacceptable adverse events. After initiating fentanyl buccal tablet therapy, all patients should continue to be regularly monitored for response, including analgesia, functioning, tolerability, and aberrant behavior. CONCLUSIONS: Fentanyl buccal tablet can be an effective and generally safe treatment for breakthrough pain when appropriate patient selection, administration, dosing, and monitoring are applied.

In the oncology community, opioids recently have become the cornerstone of cancer pain management. This has led to a rapid increase in opioid prescribing in an effort to address the growing public health problem of chronic pain. A new paradigm in noncancer pain management has emerged, that of risk assessment and stratification in opioid therapy. Techniques foreign to cancer pain management have now become commonplace in the noncancer pain setting, such as the use of monitoring compliance via urine drug screens. Amidst these strides in opioid use for pain management, cancer has been changing. The survival rate has increased, and a group of these patients with chronic pain were treated with opioid therapy. With opioid exposure being longer and against the backdrop of prescription drug abuse, the question is how much of the adaptation of the risk management paradigm in chronic pain management is to be imported to cancer pain management?

OBJECTIVE: To compare concomitant benzodiazepine (BZDs) use among chronic pain patients adherent to extended-release tapentadol (TapER) or oxycodone (OxnER) and estimate the number of lives potentially saved by switching pa-tients to the less BZD coprescribed treatment. DESIGN: Retrospective database study. SETTING: Patients were identified using the IBM MarketScan® Commercial Database. The opioid overdose death esti-mates were obtained from the US national mortality register and were used to estimate the number of lives potentially saved by switching patients to the opioid treatment with lower rates of BZD coprescribing. PATIENTS, PARTICIPANTS: The authors identified 30,213 chronic pain patients between October 2012 and March 2016. Af-ter propensity score matching, N = 2,355 and N = 6,761 patients were adherent (proportion of days covered ≥80 percent) to TapER and OxnER, respectively. INTERVENTIONS: TapER versus OxnER, during the 180-day treatment. MAIN OUTCOME MEASURE(S): Proportions of BZD coprescribing, BZD dosing patterns in matched patients, and the esti-mated number of lives potentially saved by the opioid treatment switch. RESULTS: TapER patients were less coprescribed BZDs during the treatment period (38.9 percent versus 49.2 percent, OR = 0.659, p < 0.001), and had fewer days of BZD supply per patient (mean: 49.6 versus 70.2 days, p < 0.001) with similar BZD average daily dose. Due to less frequent coprescribing of BZDs with TapER, it is estimated that ~800 deaths may have been avoided in the U.S. as a result of switching patients from OxnER to TapER. CONCLUSIONS: Among treatment-adherent patients, TapER patients had fewer BZD coprescriptions than OxnER pa-tients had. Moreover, when BZDs were coprescribed, those BZD prescriptions were for shorter periods of time. Pro-spective studies are warranted to explore rates and consequences of BZD coprescribing among opioids.
