Inhaled corticosteroid prescribing in a pediatric emergency department: Sustained success and prescription filling rates.

OBJECTIVE: To determine if improvement in Inhaled Corticosteroid (ICS) prescribing in the pediatric emergency department (PED) can be sustained after transition from intense intervention to low-intervention phase, and to determine ICS fill rates. METHODS: A Quality Improvement (QI) project began in Aug 2012. Results through Feb 2014 were previously published. In Feb 2014 interventions were scaled back to determine the sustainability of QI success. Eligible patients included children aged 2-17 seen in the PED for asthma between Feb 2014 and Sept 2016. The primary change when moving to the low-intervention phase was stopping monthly attending feedback. The primary outcome was the proportion of patients who were prescribed an ICS at the time of PED discharge. The secondary objective of this study was to determine the proportion of patients who filled their ICS prescription in the 6 months following Emergency Department (ED) visit. RESULTS: The goal rate of ICS prescribing was 75%. After transition to the low-intervention phase, the ICS prescribing rate was maintained at a median of 79% through Sept 2016. ICS fill rate in the first 30 days following ED visit was 89%, although this quickly fell to below 40% for months 2-6. CONCLUSIONS: The ICS prescribing rate remained the goal of 75% over a 2.5-year period after transition to a low-intervention phase. High ICS fill rates immediately after ED visit have been demonstrated. However, rapid decline in these rates over subsequent months suggests a need for future efforts to focus on long-term ICS adherence among children with ED visits for asthma.

Suicide Deaths With Opioid Poisoning in the United States: 1999-2014.

OBJECTIVES: To describe trends in suicides with opioid poisoning noted as a contributing cause of death. METHODS: Using National Vital Statistics data (1999-2014), we calculated age-adjusted rates of suicide with opioid poisoning (International Classification of Diseases, Tenth Revision codes T40.0-T40.4) per 100 000 population per year and annual percentage change (APC) in rates. We used Joinpoint regression to examine trends in suicide rates and proportion of suicides involving opioids. RESULTS: The annual age-adjusted death rate from suicide with opioid poisoning as a contributing cause of death increased from 0.3 per 100 000 in 1999 to 0.7 per 100 000 in 2009 (APC = 8.1%; P < .001), and remained at 0.6 to 0.7 per 100 000 through 2014. The percentage of all suicides with opioid poisoning listed as a contributing cause of death increased from 2.2% in 1999 to 4.4% in 2010 (P < .001). Rates were similar for men and women, higher among Whites than non-Whites, higher in the West, and highest for individuals aged 45 to 64 years. CONCLUSIONS: Opioid involvement in suicides has doubled since 1999. These analyses underscore the need for health care providers to assess suicidal risk in patients receiving opioids.

Quality improvement methods improve inhaled corticosteroid prescribing in the emergency department.

OBJECTIVE: Inhaled corticosteroids (ICS) are underutilized among persistent asthmatics. Because of low outpatient follow-up rates after Emergency Department (ED) visits, children are unlikely to be prescribed ICS by their primary care physician after an acute exacerbation. ED physicians have the opportunity to contribute to the delivery of preventive care in the acute care setting. Our objective was to evaluate if quality improvement (QI) methods could improve the rate of ICS initiation at ED discharge. METHODS: Within the Pediatric ED (PED) at a tertiary children's hospital, QI methods were used to encourage ICS prescribing at the time of ED discharge. Interventions focused on education at both the attending physician and resident level, process improvements designed to streamline prescribing, and directed provider feedback. This involved multiple plan-do-study-act cycles. Medical records of eligible patients were reviewed monthly to determine ICS prescribing rates. The effect of our interventions on prescribing rate was tracked over time using a run chart. RESULTS: Following our interventions, the ICS initiation rate for children seen in and discharged home from the ED with an acute asthma exacerbation increased from a baseline median rate of 11.25% to a median rate of 79% representing a significant, non-random improvement. The ICS initiation rate has been sustained for 8 months over our goal rate of 75%. CONCLUSIONS: This study demonstrates that QI methods can be used to increase inhaled corticosteroid initiation rate at the time of ED discharge and, thus, improve the delivery of preventive asthma care in the acute care setting.

Receipt of opioid analgesics by HIV-infected and uninfected patients.

BACKGROUND: Opioids are increasingly prescribed, but there are limited data on opioid receipt by HIV status. OBJECTIVES: To describe patterns of opioid receipt by HIV status and the relationship between HIV status and receiving any, high-dose, and long-term opioids. DESIGN: Cross-sectional analysis of the Veterans Aging Cohort Study. PARTICIPANTS: HIV-infected (HIV+) patients receiving Veterans Health Administration care, and uninfected matched controls. MAIN MEASURES: Pain-related diagnoses were determined using ICD-9 codes. Any opioid receipt was defined as at least one opioid prescription; high-dose was defined as an average daily dose ≥ 120 mg of morphine equivalents; long-term opioids was defined as ≥ 90 consecutive days, allowing a 30 day refill gap. Multivariable models were used to assess the relationship between HIV infection and the three outcomes. KEY RESULTS: Among the HIV+ (n = 23,651) and uninfected (n = 55,097) patients, 31 % of HIV+ and 28 % of uninfected (p < 0.001) received opioids. Among patients receiving opioids, HIV+ patients were more likely to have an acute pain diagnosis (7 % vs. 4 %), but less likely to have a chronic pain diagnosis (53 % vs. 69 %). HIV+ patients received a higher mean daily morphine equivalent dose than uninfected patients (41 mg vs. 37 mg, p = 0.001) and were more likely to receive high-dose opioids (6 % vs. 5 %, p < 0.001). HIV+ patients received fewer days of opioids than uninfected patients (median 44 vs. 60, p < 0.001), and were less likely to receive long-term opioids (31 % vs. 34 %, p < 0.001). In multivariable analysis, HIV+ status was associated with receipt of any opioids (AOR 1.40, 95 % CI 1.35, 1.46) and high-dose opioids (AOR 1.22, 95 % CI 1.07, 1.39), but not long-term opioids (AOR 0.94, 95 % CI 0.88, 1.01). CONCLUSIONS: Patients with HIV infection are more likely to be prescribed opioids than uninfected individuals, and there is a variable association with pain diagnoses. Efforts to standardize approaches to pain management may be warranted in this highly complex and vulnerable patient population.

Long-term chronic opioid therapy discontinuation rates from the TROUP study.

OBJECTIVE: To report chronic opioid therapy discontinuation rates after five years and identify factors associated with discontinuation. METHODS: Medical and pharmacy claims records from January 2000 through December 2005 from a national private health network (HealthCore), and Arkansas (AR) Medicaid were used to identify ambulatory adult enrollees who had 90 days of opioids supplied. Recipients were followed until they discontinued opioid prescription fills or disenrolled. Kaplan Meier survival models and Cox proportional hazards models were estimated to identify factors associated with time until opioid discontinuation. RESULTS: There were 23,419 and 6,848 chronic opioid recipients followed for a mean of 1.9 and 2.3 years in the HealthCore and AR Medicaid samples. Over a maximum follow up of 4.8 years, 67.0% of HealthCore and 64.9% AR Medicaid recipients remained on opioids. Recipients on high daily opioid dose (greater than 120 milligrams morphine equivalent (MED)) were less likely to discontinue than recipients taking lower doses: HealthCore hazard ratio (HR) = 0.66 (95%CI: 0.57-0.76), AR Medicaid HR = 0.66 (95%CI: 0.50-0.82). Recipients with possible opioid misuse were also less likely to discontinue: HealthCore HR = 0.83 (95%CI: 0.78-0.89), AR Medicaid HR = 0.78 (95%CI: 0.67-0.90). CONCLUSIONS: Over half of persons receiving 90 days of continuous opioid therapy remain on opioids years later. Factors most strongly associated with continuation were intermittent prior opioid exposure, daily opioid dose ≥ 120 mg MED, and possible opioid misuse. Since high dose and opioid misuse have been shown to increase the risk of adverse outcomes special caution is warranted when prescribing more than 90 days of opioid therapy in these patients.

Relationship of opioid use and dosage levels to fractures in older chronic pain patients.

BACKGROUND: Opioids have been linked to increased risk of fractures, but little is known about how opioid dose affects fracture risk. OBJECTIVE: To assess whether risk of fracture increases with opioid dose among older patients initiating sustained use of opioids for chronic non-cancer pain. DESIGN: A cohort study that uses Cox proportional hazards models to compare fracture risk among current opioid users vs. persons no longer using opioids. PARTICIPANTS: Members of an integrated health care plan (N = 2,341) age 60 years and older who received 3+ opioid prescriptions within a 90-day period for chronic, non-cancer pain between 2000 and 2005. MEASUREMENTS: Time-varying measures of opioid use and average daily dose in morphine equivalents were calculated from automated data. Fractures were identified from automated data and then validated through medical record review. RESULTS: Compared with persons not currently using opioids, opioid use was associated with a trend towards increased fracture risk (1.28 (95% CI (0.99, 1.64 )). Higher dose opioid use (>or=50 mg/day) was associated with a 9.95% annual fracture rate and a twofold increase in fracture risk (2.00 (95% CI (1.24, 3.24)). Of the fractures in the study cohort, 34% were of the hip or pelvis, and 37% were associated with inpatient care. CONCLUSIONS: Higher doses (>or=50 mg/day) of opioids for chronic non-cancer pain were associated with a 2.00 increase in risk of fracture confirmed by medical record review. Clinicians should consider fracture risk when prescribing higher-dose opioid therapy for older adults.

Age and sex trends in long-term opioid use in two large American health systems between 2000 and 2005.

OBJECTIVE: To estimate recent age- and sex-specific changes in long-term opioid prescription among patients with chronic pain in two large American Health Systems. DESIGN: Analysis of administrative pharmacy data to calculate changes in prevalence of long-term opioid prescription (90 days or more during a calendar year) from 2000 to 2005, within groups based on sex and age (18-44, 45-64, and 65 years and older). Separate analyses were conducted for patients with and without a diagnosis of a mood disorder or anxiety disorder. Changes in mean dose between 2000 and 2005 were estimated, as were changes in the rate of prescription for different opioid types (short-acting, long-acting, and non-Schedule 2). PATIENTS: Enrollees in HealthCore (N = 2,716,163 in 2000) and Arkansas Medicaid (N = 115,914 in 2000). RESULTS: Within each of the age and sex groups, less than 10% of patients with a chronic pain diagnosis in HealthCore, and less than 33% in Arkansas Medicaid, received long-term opioid prescriptions. All age, sex, and anxiety/depression groups showed similar and statistically significant increases in long-term opioid prescription between 2000 and 2005 (35-50% increase). Per-patient daily doses did not increase. CONCLUSIONS: No one group showed especially large increases in long-term opioid prescriptions between 2000 and 2005. These results argue against a recent epidemic of opioid prescribing. These trends may result from increased attention to pain in clinical settings, policy or economic changes, or provider and patient openness to opioid therapy. The risks and benefits to patients of these changes are not yet established.

Trajectories of Self-Reported Opioid Use Among Patients With HIV Engaged in Care: Results From a National Cohort Study.

BACKGROUND: No prior studies have characterized long-term patterns of opioid use regardless of source or reason for use among patients with HIV (PWH). We sought to identify trajectories of self-reported opioid use and their correlates among a national sample of PWH engaged in care. SETTING: Veterans Aging Cohort Study, a prospective cohort including PWH receiving care at 8 US Veterans Health Administration (VA) sites. METHODS: Between 2002 and 2018, we assessed past year opioid use frequency based on self-reported "prescription painkillers" and/or heroin use at baseline and follow-up. We used group-based trajectory models to identify opioid use trajectories and multinomial logistic regression to determine baseline factors independently associated with escalating opioid use compared to stable, infrequent use. RESULTS: Among 3702 PWH, we identified 4 opioid use trajectories: (1) no lifetime use (25%); (2) stable, infrequent use (58%); (3) escalating use (7%); and (4) de-escalating use (11%). In bivariate analysis, anxiety; pain interference; prescribed opioids, benzodiazepines and gabapentinoids; and marijuana use were associated with escalating opioid group membership compared to stable, infrequent use. In multivariable analysis, illness severity, pain interference, receipt of prescribed benzodiazepine medications, and marijuana use were associated with escalating opioid group membership compared to stable, infrequent use. CONCLUSION: Among PWH engaged in VA care, 1 in 15 reported escalating opioid use. Future research is needed to understand the impact of psychoactive medications and marijuana use on opioid use and whether enhanced uptake of evidence-based treatment of pain and psychiatric symptoms can prevent escalating use among PWH.

The role of opioid prescription in incident opioid abuse and dependence among individuals with chronic noncancer pain: the role of opioid prescription.

OBJECTIVE: Increasing rates of opioid use disorders (OUDs) (abuse and dependence) among patients prescribed opioids are a significant public health concern. We investigated the association between exposure to prescription opioids and incident OUDs among individuals with a new episode of a chronic noncancer pain (CNCP) condition. METHODS: We utilized claims data from the HealthCore Database for 2000 to 2005. The dataset included all individuals aged 18 and over with a new CNCP episode (no diagnosis in the prior 6 mo), and no opioid use or OUD in the prior 6 months (n=568,640). We constructed a single multinomial variable describing prescription on opioid days supply (none, acute, and chronic) and average daily dose (none, low dose, medium dose, and high dose), and examined the association between this variable and an incident OUD diagnosis. RESULTS: Patients with CNCP prescribed opioids had significantly higher rates of OUDs compared with those not prescribed opioids. Effects varied by average daily dose and days supply: low dose, acute (odds ratio [OR]=3.03; 95% confidence interval [CI], 2.32, 3.95); low dose, chronic (OR=14.92; 95% CI, 10.38, 21.46); medium dose, acute (OR=2.80; 95% CI, 2.12, 3.71); medium dose, chronic (OR=28.69; 95% CI, 20.02, 41.13); high dose, acute (OR=3.10; 95% CI, 1.67, 5.77); and high dose, chronic (OR=122.45; 95% CI, 72.79, 205.99). CONCLUSIONS: Among individuals with a new CNCP episode, prescription opioid exposure was a strong risk factor for incident OUDs; magnitudes of effects were large. Duration of opioid therapy was more important than daily dose in determining OUD risk.

Predictors of change in pain and physical functioning among post-menopausal women with recurrent pain conditions in the women's health initiative observational cohort.

UNLABELLED: Pain complaints are commonly reported symptoms among postmenopausal women and can have significant effects on health-related quality of life. We sought to identify medical and psychosocial factors that predict changes in pain and overall physical functioning over a 3-year period among postmenopausal women with recurrent pain conditions. We examined data from postmenopausal women age 50 to 79 with recurrent pain conditions (low back pain, neck pain, headache or migraines, or joint pain or stiffness) over a 3-year period using the Women's Health Initiative Observational Study Cohort (N = 67,963). Multinomial logistic regression models controlling for demographic and clinical characteristics were used to identify baseline predictors of change in the SF-36 subscales for pain and physical functioning between baseline and 3-year follow-up. Body mass index (BMI) was associated with worsening of pain (OR [95% CI] 1.54 [1.45-1.63] for BMI ≥30) and physical functioning (1.83 [1.71-1.95] for BMI ≥30). A higher reported number of nonpain symptoms, higher medical comorbidity, and a positive screen for depression (1.13 [1.05-1.22] for worsened pain) were also associated with worsening of pain and physical functioning. Baseline prescription opioid use was also associated with lack of improvement in pain (OR .42, 95% CI .36-.49) and with worsened physical functioning (1.25 [1.04-1.51]). PERSPECTIVE: This study presents prospective data on change in pain and physical functioning in postmenopausal women over a 3-year period. Our results suggest depression, nonpain physical symptoms, obesity, and possibly opioid treatment are associated with worse long-term pain outcomes in this population.

Emergency department visits among recipients of chronic opioid therapy.

BACKGROUND: There has been an increase in overdose deaths and emergency department visits (EDVs) involving use of prescription opioids, but the association between opioid prescribing and adverse outcomes is unclear. METHODS: Data were obtained from administrative claim records from Arkansas Medicaid and HealthCore commercially insured enrollees, 18 years and older, who used prescription opioids for at least 90 continuous days within a 6-month period between 2000 and 2005 and had no cancer diagnoses. Regression analysis was used to examine risk factors for EDVs and alcohol- or drug-related encounters (ADEs) in the 12 months following 90 days or more of prescribed opioids. RESULTS: Headache, back pain, and preexisting substance use disorders were significantly associated with EDVs and ADEs. Mental health disorders were associated with EDVs in HealthCore enrollees and with ADEs in both samples. Opioid dose per day was not consistently associated with EDVs but doubled the risk of ADEs at morphine-equivalent doses over 120 mg/d. Use of short-acting Drug Enforcement Agency Schedule II opioids was associated with EDVs compared with use of non-Schedule II opioids alone (relative risk range, 1.09-1.74). Use of Schedule II long-acting opioids was strongly associated with ADEs (relative risk range, 1.64-4.00). CONCLUSIONS: Use of Schedule II opioids, headache, back pain, and substance use disorders are associated with EDVs and ADEs among adults prescribed opioids for 90 days or more. It may be possible to increase the safety of chronic opioid therapy by minimizing the prescription of Schedule II opioids in these higher-risk recipients.

Risks for opioid abuse and dependence among recipients of chronic opioid therapy: results from the TROUP study.

OBJECTIVE: To estimate the prevalence of and risk factors for opioid abuse/dependence in long-term users of opioids for chronic pain, including risk factors for opioid abuse/dependence that can potentially be modified to decrease the likelihood of opioid abuse/dependence, and non-modifiable risk factors for opioid abuse/dependence that may be useful for risk stratification when considering prescribing opioids. METHODS: We used claims data from two disparate populations, one national, commercially insured population (HealthCore) and one state-based, publicly insured (Arkansas Medicaid). Among users of chronic opioid therapy, we regressed claims-based diagnoses of opioid abuse/dependence on patient characteristics, including physical health, mental health and substance abuse diagnoses, sociodemographic factors, and pharmacological risk factors. RESULTS: Among users of chronic opioid therapy, 3% of both the HealthCore and Arkansas Medicaid samples had a claims-based opioid abuse/dependence diagnosis. There was a strong inverse relationship between age and a diagnosis of opioid abuse/dependence. Mental health and substance use disorders were associated with an increased risk of opioid abuse/dependence. Effects of substance use disorders were especially strong, although mental health disorders were more common. Concerning opioid exposure; lower days supply, lower average doses, and use of Schedule III-IV opioids only, were all associated with lower likelihood of a diagnosis of opioid abuse/dependence. CONCLUSION: Opioid abuse and dependence are diagnosed in a small minority of patients receiving chronic opioid therapy, but this may under-estimate actual misuse. Characteristics of the patients and of the opioid therapy itself are associated with the risk of abuse and dependence.

An analysis of heavy utilizers of opioids for chronic noncancer pain in the TROUP study.

CONTEXT: Although opioids are increasingly used for chronic noncancer pain (CNCP), we know little about opioid dosing patterns among individuals with CNCP in usual care settings, and how these are changing over time. OBJECTIVES: To investigate the distribution of mean daily dose and mean days supply among patients with CNCP in two disparate populations, one national and commercially insured population (HealthCore) and one state based and publicly insured (Arkansas Medicaid), for years 2000 and 2005. METHODS: For individuals with any opioid use, we calculated the distribution of mean daily dose (in milligram morphine equivalents), mean days supply in a year, mean annual dose, and patient characteristics associated with heavy utilizers of opioids. RESULTS: Between 2000 and 2005, across all percentiles, there was little change in the mean daily opioid dose. In HealthCore, mean days supply increased most rapidly at the top end of the days supply distribution, whereas in Arkansas Medicaid, the greatest increases were near the median of days supply. In HealthCore, the top 5% of users accounted for 70% of total use (measured in milligram morphine equivalents), and the top 5% of Arkansas Medicaid users accounted for 48% of total use. The likelihood of heavy opioid utilization was increased among individuals with multiple pain conditions, and in HealthCore, among those with mental health and substance use disorders. CONCLUSION: Opioid use is heavily concentrated among a small percent of patients. The characteristics of these high utilizers need to be further established, and the benefits and risks of their treatment evaluated.

Risks for possible and probable opioid misuse among recipients of chronic opioid therapy in commercial and medicaid insurance plans: The TROUP Study.

The use of chronic opioid therapy (COT) for chronic non-cancer pain (CNCP) has increased dramatically in the past two decades. There has also been a marked increase in the abuse of prescribed opioids and in accidental opioid overdose. Misuse of prescribed opioids may link these trends, but has thus far only been studied in small clinical samples. We therefore sought to validate an administrative indicator of opioid misuse among large samples of recipients of COT and determine the demographic, clinical, and pharmacological risks associated with possible and probable opioid misuse. A total of 21,685 enrollees in commercial insurance plans and 10,159 in Arkansas Medicaid who had at least 90 days of continuous opioid use 2000-2005 were studied for one year. Criteria were developed for possible and probable opioid misuse using administrative claims data concerning excess days supplied of short-acting and long-acting opioids, opioid prescribers and opioid pharmacies. We estimated possible misuse at 24% of COT recipients in the commercially insured sample and 20% in the Medicaid sample and probable misuse at 6% in commercially insured and at 3% in Medicaid. Among non-modifiable factors, younger age, back pain, multiple pain complaints and substance abuse disorders identify patients at high risk for misuse. Among modifiable factors, treatment with high daily dose opioids (especially >120 mg MED per day) and short-acting Schedule II opioids appears to increase the risk of misuse. The consistency of the findings across diverse patient populations and the varying levels of misuse suggest that these results will generalize broadly, but await confirmation in other studies.

Trends in use of opioids for chronic noncancer pain among individuals with mental health and substance use disorders: the TROUP study.

OBJECTIVES: Use of prescription opioids for chronic pain is increasing, as is abuse of these medications, though the nature of the link between these trends is unclear. These increases may be most marked in patients with mental health (MH) and substance use disorders (SUDs). We analyzed trends between 2000 and 2005 in opioid prescribing among individuals with noncancer pain conditions (NCPC), with and without MH and SUDs. METHODS: Secondary data analysis of longitudinal administrative data from 2 dissimilar populations: a national, commercially insured population and Arkansas Medicaid enrollees. We examined these opioid outcomes: (1) rates of any prescription opioid use in the past year, (2) rates of chronic use of prescription opioids (greater than 90 d in the past year), (3) mean days supply of opioids, (4) mean daily opioid dose in morphine equivalents, and (5) percentage of total opioid dose that was Schedule II opioids. RESULTS: In 2000, among individuals with NCPC, chronic opioid use was more common among those with a MH or SUD than among those without in commercially insured (8% vs. 3%, P<0.001) and Arkansas Medicaid (20% vs. 13%, P<0.001) populations. Between 2000 and 2005, in commercially insured, rates of chronic opioid use increased by 34.9% among individuals with an MH or SUD and 27.8% among individuals without these disorders. In Arkansas Medicaid chronic, opioid use increased by 55.4% among individuals with an MH or SUD and 39.8% among those without. DISCUSSION: Chronic use of prescription opioids for NCPC is much higher and growing faster in patients with MH and SUDs than in those without these diagnoses. Clinicians should monitor the use of prescription opioids in these vulnerable groups to determine whether opioids are substituting for or interfering with appropriate MH and substance abuse treatment.

Trends in long-term opioid therapy for noncancer pain among persons with a history of depression.

OBJECTIVE: We report trends in long-term opioid use among patients with a history of depression from two large health plans. METHODS: Using claims data, age- and gender-adjusted rates for long-term (>90 days) opioid use episodes were calculated for 1997-2005, comparing those with and without a depression diagnosis in the prior 2 years. Opioid use characteristics were calculated for those with a long-term episode in 2005. RESULTS: Incident and prevalent long-term opioid use rates were three times higher in those with a history of depression. Prevalent long-term use per 1000 in patients with a history of depression increased from 69.8 to 125.9 at Group Health and from 84.3 to 117.5 at Kaiser Permanente of Northern California between 1997 and 2005. Those with a history of depression were more likely to receive a higher average daily dose, greater days supply, and Schedule II opioids than nondepressed persons. CONCLUSION: Persons with a history of depression are more likely to receive long-term opioid therapy for noncancer pain than those without a history of depression. Results suggest that long-term opioid therapy for noncancer pain is being prescribed to a different population in clinical practice than the clinical trial populations where opioid efficacy has been established.

Suicidal thoughts and behavior among adults with self-reported pain conditions in the national comorbidity survey replication.

UNLABELLED: We sought to examine whether the presence of a noncancer pain condition is independently associated with an increased risk for suicidal ideation, plan, or attempt after adjusting for sociodemographic and psychiatric risk factors for suicide and whether risk differs by specific type of pain. We analyzed data from the National Comorbidity Survey Replication, a household survey of U.S. civilian adults age 18 years and older (n = 5692 respondents). Pain conditions, nonpain medical conditions, and suicidal history were obtained by self-report. DSM-IV mood, anxiety, and substance use disorders were assessed using the World Health Organization's Composite International Diagnostic Interview. Antisocial and borderline personality traits were assessed with the International Personality Disorder Examination screening questionnaire. In unadjusted logistic regression analyses, the presence of any pain condition was associated with lifetime and 12-month suicidal ideation, plan, and attempt. After controlling for demographic, medical, and mental health covariates, the presence of any pain condition remained significantly associated with lifetime suicidal ideation (odds ratio, 1.4; 95% confidence interval, 1.1-1.8) and plan. Among pain subtypes, severe or frequent headaches and "other" chronic pain remained significantly associated with lifetime suicidal ideation and plan; "other" chronic pain was also associated with attempt. PERSPECTIVE: The risk for suicidal thoughts and behaviors that may accompany back, neck, and joint pain can be accounted for by comorbid mental health disorders. There may be additional risk accompanying frequent headaches and "other" chronic pain that is secondary to psychosocial processes not captured by the mental disorders assessed.

Employment outcomes of persons with a mental disorder and comorbid chronic pain.

OBJECTIVE: This study examined the independent and interactive effects of common mental disorders and chronic pain conditions on employment and work outcomes among individuals under 65 years old. METHODS: Cross-sectional data were analyzed from the second wave of Healthcare for Communities (HCC2), a household telephone survey of U.S. civilian adults conducted in 2000-2001 (N=5,328). Common mental disorders were assessed by using the short-form version of the World Health Organization's Composite International Diagnostic Interview. Chronic pain conditions and employment outcomes were identified by self-report. Logistic and linear regression analyses were used to provide estimates for work impairment on the basis of the presence of a mental disorder or a chronic pain condition or both. RESULTS: The interaction between presence of a mental disorder and presence of a chronic pain condition was significantly associated with no work for pay in the past 12 months (odds ratio=2.3, 95% confidence interval=1.2-4.2) and number of days of work missed in the past month because of health (regression coefficient=1.47, SE=.59). In stratified analyses this effect persisted for women but not for men. The presence of a mental disorder and the presence of a chronic pain condition were each independently associated with limitations in work and any work missed in the past 30 days because of health, although the interaction was not significant. CONCLUSIONS: Mental disorders and chronic pain are each associated with work disability. Mental disorders are more strongly associated with some work disability outcomes when they are accompanied by chronic pain, especially among women.

Mental health service use by older adults: the role of chronic pain.

OBJECTIVE: Mental health disorders commonly co-occur in patients with chronic pain, but little is known about the role of chronic pain in mental health service use. In this study, the authors explored the role of chronic pain in mental health service use by adults according to age group. METHOD: The authors conducted a cross-sectional analysis of survey data from the second wave of the Health Care for Communities telephone survey collected in 2000-2001. Participants consisted of U.S. civilian adults (N = 6629) from randomly selected U.S. households. Common mental disorders were assessed using the short-form versions of the World Health Organization's Composite International Diagnostic Interview. Chronic pain conditions and mental health services received were identified by self-report. Physical and mental functioning was assessed using the Short Form-12. RESULTS: Adults older than age 60 had higher rates of chronic pain and lower rates of mental health service use compared with those aged 18-60 years. In multiple logistic regression models, an interaction effect was found between age and chronic pain (odds ratio: 3.0 [1.1-8.0]) with chronic pain significantly increasing the odds of any mental health care in the past year in adults older than 60 years of age. CONCLUSIONS: Chronic pain increases the likelihood of mental health service use among older adults. Chronic pain may facilitate the presentation of distress in medical settings for these adults.

Trends in use of opioids for non-cancer pain conditions 2000-2005 in commercial and Medicaid insurance plans: the TROUP study.

Opioids are widely prescribed for non-cancer pain conditions (NCPC), but there have been no large observational studies in actual clinical practice assessing patterns of opioid use over extended periods of time. The TROUP (Trends and Risks of Opioid Use for Pain) study reports on trends in opioid therapy for NCPC in two disparate populations, one national and commercially insured population (HealthCore plan data) and one state-based and publicly-insured (Arkansas Medicaid) population over a six year period (2000-2005). We track enrollees with the four most common NCPC conditions: arthritis/joint pain, back pain, neck pain, headaches, as well as HIV/AIDS. Rates of NCPC diagnosis and opioid use increased linearly during this period in both groups, with the Medicaid group starting at higher rates and the HealthCore group increasing more rapidly. The proportion of enrollees receiving NCPC diagnoses increased (HealthCore 33%, Medicaid 9%), as did the proportion of enrollees with NCPC diagnoses who received opioids (HealthCore 58%, Medicaid 29%). Cumulative yearly opioid dose (in mg. morphine equivalents) received by NCPC patients treated with opioids increased (HealthCore 38%, Medicaid 37%) due to increases in number of days supplied rather than dose per day supplied. Use of short-acting Drug Enforcement Administration Schedule II opioids increased most rapidly, both in proportion of NCPC patients treated (HealthCore 54%, Medicaid 38%) and in cumulative yearly dose (HealthCore 95%, Medicaid 191%). These trends have occurred without any significant change in the underlying population prevalence of NCPC or new evidence of the efficacy of long-term opioid therapy and thus likely represent a broad-based shift in opioid treatment philosophy.
