Abstract Purpose Opioid misuse in the context of chronic opioid therapy (COT) is a growing concern. Depression may be a risk factor for opioid misuse, but it has been difficult to tease out the ...contribution of co-occurring substance abuse. This study aims to examine whether there is an association between depression and opioid misuse in patients receiving COT who have no history of substance abuse. Methods A telephone survey was conducted at Group Health Cooperative and Kaiser Permanente of Northern California. We interviewed 1,334 patients on COT for noncancer pain who had no history of substance abuse. Patients were asked about 3 forms of opioid misuse: (1) self-medicating for symptoms other than pain, (2) self-increasing doses, and (3) giving to or getting opioids from others. Depression was evaluated by the 8-item Patient Health Questionnaire (PHQ-8). Results Compared with patients who were not depressed (PHQ-8 score 0 to 4), patients with moderate depression (PHQ-8 score 10 to 14) and severe depression (PHQ-8 score 15 or higher) were 1.8 and 2.4 times more likely, respectively, to misuse their opioid medications for non–pain symptoms. Patients with mild (PHQ-8 score 5 to 9), moderate, and severe depression were 1.9, 2.9, and 3.1 times more likely, respectively, to misuse their opioid medications by self-increasing their dose. There was no statistically significant association between depression and giving opioids to or getting them from others. Conclusion In patients with no substance abuse history, depressive symptoms are associated with increased rates of some forms of self-reported opioid misuse. Clinicians should be alert to the risk of patients with depressive symptoms using opioids to relieve these symptoms and thereby using more opioids than prescribed.

Abstract Increased opioid prescribing for back pain and other chronic musculoskeletal pain conditions has been accompanied by dramatic increases in prescription-opioid addiction and fatal overdose. ...Opioid-related risks appear to increase with dose. Although short-term randomised trials of opioids for chronic pain have found modest analgesic benefits (a one-third reduction in pain intensity on average), the long-term safety and effectiveness of opioids for chronic musculoskeletal pain remains unknown. Given the lack of large, long-term randomised trials, recent epidemiologic data suggest the need for caution when considering long-term use of opioids to manage chronic musculoskeletal pain, particularly at higher dosage levels. Principles for achieving more selective and cautious use of opioids for chronic musculoskeletal pain are proposed.
Abstract Purpose Although psychosocial and clinical factors have been found to be associated with hypoglycemic episodes in patients with diabetes, few studies have examined the association of ...depression with severe hypoglycemic episodes. This study examined the prospective association of depression with risk of hypoglycemic episodes requiring either an emergency department visit or hospitalization. Methods In a longitudinal cohort study, a sample of 4,117 patients with diabetes enrolled between 2000 and 2002 were observed from 2005 to 2007. Meeting major depression criteria on the Patient Health Questionnaire-9 was the exposure of interest, and the outcome of interest was an International Classification of Disease, Ninth Revision code for a hypoglycemic episode requiring an emergency department visit or hospitalization. Proportional hazard models were used to analyze the association of baseline depression and risk of one or more severe hypoglycemic episodes. Poisson regression was used to determine whether depression status was associated with the number of hypoglycemic episodes. Results After adjusting for sociodemographic, clinical measures of diabetes severity, non–diabetes-related medical comorbidity, prior hypoglycemic episodes, and health risk behaviors, depressed compared with nondepressed patients who had diabetes had a significantly higher risk of a severe hypoglycemic episode (hazard ratio = 1.42, 95% CI, 1.03–1.96) and a greater number of hypoglycemic episodes (odds ratio = 1.34, 95% CI, 1.03–1.74). Conclusion Depression was significantly associated with time to first severe hypoglycemic episode and number of hypoglycemic episodes. Research assessing whether recognition and effective treatment of depression among persons with diabetes prevents severe hypoglycemic episodes is needed.
Little is known about the extent or severity of untreated mental disorders, especially in less-developed countries.
To estimate prevalence, severity, and treatment of Diagnostic and Statistical ...Manual of Mental Disorders, Fourth Edition (DSM-IV) mental disorders in 14 countries (6 less developed, 8 developed) in the World Health Organization (WHO) World Mental Health (WMH) Survey Initiative.
Face-to-face household surveys of 60 463 community adults conducted from 2001-2003 in 14 countries in the Americas, Europe, the Middle East, Africa, and Asia.
The DSM-IV disorders, severity, and treatment were assessed with the WMH version of the WHO Composite International Diagnostic Interview (WMH-CIDI), a fully structured, lay-administered psychiatric diagnostic interview.
The prevalence of having any WMH-CIDI/DSM-IV disorder in the prior year varied widely, from 4.3% in Shanghai to 26.4% in the United States, with an interquartile range (IQR) of 9.1%-16.9%. Between 33.1% (Colombia) and 80.9% (Nigeria) of 12-month cases were mild (IQR, 40.2%-53.3%). Serious disorders were associated with substantial role disability. Although disorder severity was correlated with probability of treatment in almost all countries, 35.5% to 50.3% of serious cases in developed countries and 76.3% to 85.4% in less-developed countries received no treatment in the 12 months before the interview. Due to the high prevalence of mild and subthreshold cases, the number of those who received treatment far exceeds the number of untreated serious cases in every country.
Reallocation of treatment resources could substantially decrease the problem of unmet need for treatment of mental disorders among serious cases. Structural barriers exist to this reallocation. Careful consideration needs to be given to the value of treating some mild cases, especially those at risk for progressing to more serious disorders.
High impact chronic pain (HICP) is a recently proposed concept for treatment stratifying patients with chronic pain and monitoring their progress. The goal is to reduce the impact of chronic pain on ...the individual, their family, and society. The US National Pain Strategy defined HICP as the chronic pain associated with substantial restrictions on participation in work, social, and self-care activities for at least 6 months. To understand the meaning and characteristics of HICP from the younger (<65 years old) and older adults (≥65 years old) with chronic pain, our study examined patients' perceived pain impact between the two age groups. We also characterize the degree of pain impact, assessed with the Patient-Reported Outcomes Measurement Information System (PROMIS) pain interference (PI), between adults and older adults with HICP. We recruited patients at a tertiary pain clinic. The survey included open-ended questions about pain impact, the Graded Chronic Pain Scale-Revised to identify patients' meeting criteria for HICP, and the Patient-Reported Outcomes Measurement Information System (PROMIS
) 8-item PI short form (v.8a). A total of 55 younger adults (65.5% women, 72.7% HICP, mean age = 55.0 with
of 16.2) and 28 older adults (53.6% women, 64.3% HICP, mean age = 72.6 with
of 5.4) with chronic pain participated in this study. In response to an open-ended question in which participants were asked to list out the areas of major impact pain, those with HICP in the younger group most commonly listed work, social activity, and basic physical activity (e.g., walking and standing); for those in the older group, basic physical activity, instrumental activity of daily living (e.g., housework, grocery shopping), and participating in social or fun activity for older adults with HICP were the most common. A 2 × 2 ANOVA was conducted using age (younger adults vs. older adults) and HICP classification (HICP vs. No HICP). A statistically significant difference was found in the PROMIS-PI T-scores by HICP status (HICP:
= 58.4,
= 6.3; No HICP:
= 67.8,
= 6.3), but not by age groups with HICP. In conclusion, perceived pain impacts were qualitatively, but not quantitatively different between younger and older adults with HICP. We discuss limitations and offer recommendations for future research.
To estimate the prevalence of comorbidity among people with arthritis in the US adult population and to determine the role of comorbidity in accounting for the association of arthritis with days out ...of role (a measure of inability to work or carry out normal activities).
Data come from the National Comorbidity Survey Replication (NCS-R), a nationally representative household survey of 9,282 respondents ages 18 and older carried out in 2001 to 2003. Arthritis was assessed by self-report in a chronic-conditions checklist, along with a wide range of other physical conditions. Mental and substance use disorders were ascertained with the World Health Organization Composite International Diagnostic Interview (CIDI). Number of days out of role was assessed for the 30 days before the interview.
Arthritis was reported by 27.3% of respondents, 80.9% of whom also reported at least one other physical or mental disorder, including 45.6% with another chronic pain condition, 62.3% with another chronic physical condition, and 24.3% with a 12-month mental disorder. Arthritis was significantly associated with days out of role, but comorbidity explained more than half of this association. No significant interactions were found between arthritis and the other conditions in predicting days out of role.
Comorbidity is the rule rather than the exception among people with arthritis. Comorbidity accounts for most of the days out of role associated with arthritis. The societal burden of arthritis needs to be understood and managed within the context of these comorbid conditions.
The use of chronic opioid therapy (COT) has risen dramatically in recent years, especially among women. However, little is known about factors influencing overall pain and function (global pain ...status) among COT users. Characterizing the typical experiences of COT patients by age-sex group could help clinicians and patients better weigh the risks and benefits of COT. Thus, we sought to characterize global pain status among COT users in community practice by age and sex.
Telephone survey of 2,163 health plan members aged 21-80 years using COT. We assessed average/usual pain (0-10 scale); pain-related interference (0-10); activity limitation days, last 3 months; and pain impact, last 2 weeks (0-11). Status on each indicator was classified as low (better pain/function), moderate, or high (worse pain/function). Global pain status was categorized as favorable if 2-4 indicators were low and 0-1 was high and unfavorable if 2-4 indicators were high and 0-1 was low.
Among female COT patients, 15% (vs. 26% of males) had favorable global pain status and 59% (vs. 42% of males) had unfavorable status. Under age 65 years, women fared more poorly than men on every indicator. Among 65- to 80-year-olds, women and men had similar global pain status.
Although pain and function among COT users vary considerably, only one in five reported low pain levels and high levels of function. Young and middle-aged women seem to be at particularly high risk for unfavorable global pain status. More research is needed about how to best manage pain in this group.
