Untreated Opioid Use Disorder and Health-Related Quality of Life Among Syringe Service Program Clients.

This cross-sectional study explores health-related quality of life (HRQoL) and the challenges to physical, emotional, and social functioning among individuals with opioid use disorder.

Withdrawal catastrophizing scale: initial psychometric properties and implications for the study of opioid use disorder and hyperkatifeia.

Background: Discovery of modifiable factors influencing subjective withdrawal experience might advance opioid use disorder (OUD) research and precision treatment. This study explores one factor - withdrawal catastrophizing - a negative cognitive and emotional orientation toward withdrawal characterized by excessive fear, worry or inability to divert attention from withdrawal symptoms.Objectives: We define a novel concept - withdrawal catastrophizing - and present an initial evaluation of the Withdrawal Catastrophizing Scale (WCS).Methods: Prospective observational study (n = 122, 48.7% women). Factor structure (exploratory factor analysis) and internal consistency (Cronbach's α) were assessed. Predictive validity was tested via correlation between WCS and next-day subjective opiate withdrawal scale (SOWS) severity. The clinical salience of WCS was evaluated by correlation between WCS and withdrawal-motivated behaviors including risk taking, OUD maintenance, OUD treatment delay, history of leaving the hospital against medical advice and buprenorphine-precipitated withdrawal.Results: WCS was found to have a two-factor structure (distortion and despair), strong internal consistency (α = .901), and predictive validity - Greater withdrawal catastrophizing was associated with next-day SOWS (rs (99) = 0.237, p = .017). Withdrawal catastrophizing was also correlated with risk-taking behavior to relieve withdrawal (rs (119) = 0.357, p < .001); withdrawal-motivated OUD treatment avoidance (rs (119) = 0.421, p < .001), history of leaving the hospital against medical advice (rs (119) = 0.373, p < .001) and buprenorphine-precipitated withdrawal (rs (119) = 0.369, p < .001).Conclusion: This study provides first evidence of withdrawal catastrophizing as a clinically important phenomenon with implications for the future study and treatment of OUD.

Nociplastic Pain and Pain-Motivated Drinking in Alcohol Use Disorder.

Heavy chronic alcohol use may produce pain amplification through neurochemical and neuroplastic changes at multiple levels of the nervous system. Similar changes are thought to underlie nociplastic pain. The American College of Rheumatology Fibromyalgia Survey has been used as a surrogate for nociplastic pain, including among individuals with alcohol use disorder (AUD). However, studies linking nociplastic pain to pain-motivated drinking are lacking. The present study aimed to determine if nociplastic pain is associated with pain-motivated drinking in AUD. To achieve this aim, a new scale-the Pain-Motivated Drinking Scale (PMDS)-was developed to measure how often participants were motivated by pain to drink alcohol. Measurement properties of this new scale were determined, including its factor structure, internal consistency reliability, and construct validity. In this cross-sectional observational study, participants with AUD (n = 138) were consecutively recruited from the patient pool at an academic addiction treatment facility. Seventy-two percent (95, 72.0%) reported they drank alcohol "to get relief from physical pain" at least some of the time, and over forty-two percent (56, 42.4%) reported pain relief motivated their drinking at least half of the time. PMDS had a single-factor structure, strong internal consistency reliability, and construct validity. A multiple hierarchical linear regression was run to determine if nociplastic pain was associated with pain-motivated drinking. Nociplastic pain was associated with PMDS even after controlling for potential confounders and pain severity. These findings suggest nociplastic pain is uniquely associated with pain-motivated drinking in AUD. PERSPECTIVE: Nociplastic pain is independently associated with pain-motivated drinking in alcohol use disorder (AUD). The Pain-Motivated Drinking Scale (PMDS) is a new scale to measure how often people drink to cope with pain. PMDS has promising psychometric properties. Nociplastic pain may be uniquely associated with pain-motivated drinking in AUD.

The Perceived Role of Withdrawal in Maintaining Opioid Addiction among Adults with Untreated Opioid Use Disorder: A Survey of Syringe Exchange Program Participants.

Background: Withdrawal is believed to play a central role in the brain disease model of addiction. However, little research describes withdrawal-motives among untreated individuals in community settings. Methods: This cross-sectional study surveyed syringe exchange program participants (n = 139) with untreated opioid use disorder (OUD) in Columbus, Ohio from January 10th to March 25th, 2023, to assess their perceptions of the role of withdrawal in OUD maintenance, treatment delay, and OUD's refractoriness to buprenorphine. Participants responded to a survey including DSM-5 OUD criteria, demographics, and questions about substance use and opioid withdrawal. Participant ages ranged from 21 to 65 years with a mean age of 37.5 years and standard deviation of 8.1. The racial distribution of the sample was as follows: 81% White/Caucasian, 12% Black/African American, 3% Native American or Alaskan Native. Results: Sixty-six percent of participants agreed, or strongly agreed that opioid withdrawal was "the most important reason" they had been unable to stop using opioids. Almost seventy-one percent agreed, or strongly agreed that worry about opioid withdrawal had caused them to "put off or delay" OUD treatment. Although all participants had active, untreated OUD at the time of recruitment, most (85%) had previously tried buprenorphine, and the majority (78%) reported having experienced buprenorphine-precipitated withdrawal. Conclusions: Among this community sample of individuals with untreated OUD, withdrawal was perceived to have an important role in maintaining OUD, including by motivating OUD treatment delay. Prior buprenorphine-precipitated withdrawal was common, suggesting aversion to withdrawal might possibly be associated with OUD's refractoriness to buprenorphine.

Years of Life Lost to Firearm Suicide Among Young People in the US.

This cross-sectional study examines years of life lost among the top 3 causes of death and compares firearm suicide with other methods of suicide among individuals aged 10 to 24 years in the US.

Years of life lost due to deaths of despair and COVID-19 in the United States in 2020: patterns of excess mortality by gender, race and ethnicity.

BACKGROUND: In 2020 COVID-19 was the third leading cause of death in the United States. Increases in suicides, overdoses, and alcohol related deaths were seen-which make up deaths of despair. How deaths of despair compare to COVID-19 across racial, ethnic, and gender subpopulations is relatively unknown. Preliminary studies showed inequalities in COVID-19 mortality for Black and Hispanic Americans in the pandemic's onset. This study analyzes the racial, ethnic and gender disparities in years of life lost due to COVID-19 and deaths of despair (suicide, overdose, and alcohol deaths) in 2020. METHODS: This cross-sectional study calculated and compared years of life lost (YLL) due to Deaths of Despair and COVID-19 by gender, race, and ethnicity. YLL was calculated using the CDC WONDER database to pull death records based on ICD-10 codes and the Social Security Administration Period Life Table was used to get estimated life expectancy for each subpopulation. RESULTS: In 2020, COVID-19 caused 350,831 deaths and 4,405,699 YLL. By contrast, deaths of despair contributed to 178,598 deaths and 6,045,819 YLL. Men had more deaths and YLL than women due to COVID-19 and deaths of despair. Among White Americans and more than one race identification both had greater burden of deaths of despair YLL than COVID-19 YLL. However, for all other racial categories (Native American/Alaskan Native, Asian, Black/African American, Native Hawaiian/Pacific Islander) COVID-19 caused more YLL than deaths of despair. Also, Hispanic or Latino persons had disproportionately higher mortality across all causes: COVID-19 and all deaths of despair causes. CONCLUSIONS: This study found greater deaths of despair mortality burden and differences in burden across gender, race, and ethnicity in 2020. The results indicate the need to bolster behavioral health research, support mental health workforce development and education, increase access to evidence-based substance use treatment, and address systemic inequities and social determinants of deaths of despair and COVID-19.

Central sensitization in alcohol use disorder: correlates of pain, addiction and health-related quality of life.

BACKGROUND: Central sensitization is an important mechanism underlying many chronic pain conditions. Chronic pain and alcohol use disorder (AUD) are highly comorbid. Despite great scientific interest in brain mechanisms linking chronic pain and AUD, progress has been impeded by difficulty assessing central sensitization in AUD. OBJECTIVE: The present study is the first to employ a validated surrogate measure to describe central sensitization in a clinical sample with AUD. METHODS: Participants with AUD (n = 99) were recruited from an academic addiction treatment center. A well-established surrogate measure of central sensitization, The American College of Rheumatology Fibromyalgia Survey Criteria (ACRFMS) was administered. Participants also responded to questions about quality of life (RAND-36), and AUD. Descriptive analyses and Spearman's rho correlations were performed. RESULTS: Chronic pain and evidence of central sensitization were prevalent. Greater central sensitization was associated with worse health-related quality of life. Participants higher in central sensitization expressed greater endorsement of pain as a reason for AUD onset, maintenance, escalation, treatment delay, and relapse. CONCLUSION: The present study bolsters prior assertions that AUD and chronic pain might compound one another via progressive sensitization of shared brain circuitry. These results may inform future mechanistic research and precision AUD treatment.

Years of life lost due to unintentional drug overdose among perinatal individuals in the United States.

BACKGROUND: The United States has one of the highest maternal mortality rates of developing countries, but the contribution of perinatal drug overdose is not known. Communities of color also have higher rates of maternal morbidity and mortality when compared to White communities, however the contribution due to overdose has not yet been examined in this population. OBJECTIVES: To quantify the years of life lost due to unintentional overdose in perinatal individuals from 2010 to 2019 and assess for disparity by race. STUDY DESIGN: This was a cross-sectional retrospective study with summary-level mortality statistics for the years 2010-2019 obtained from the Centers for Disease Control (CDC) Wide-Ranging Online Data for Epidemiologic Research (WONDER) mortality file. A total of 1,586 individuals of childbearing age (15-44 years) who died during pregnancy or six weeks postpartum (perinatal) from unintentional overdose in the United States from January 1, 2010 to December 31, 2019 were included. Total years of life lost (YLL) was calculated and summated for White, Black, Hispanic, Asian/Pacific Islander, and American Indian/Native Alaska women. Additionally, the top three overall causes of death were also identified for women in this age group for comparison. RESULTS: Unintentional drug overdose accounted for 1,586 deaths and 83,969.78 YLL in perinatal individuals from 2010 to 2019 in the United States. Perinatal American Indian/Native American individuals had a disproportionate amount of YLL when compared to other ethnic groups, with 2.39% of YLL due to overdose, while only making up 0.80% of the population. During the last two years of the study, only American Indian/Native American and Black individuals had increased rates of mortality when compared to other races. During the ten-year study period, when including the top three causes of mortality, unintentional drug overdoses made up 11.98% of the YLL overall and 46.39% of accidents. For the years 2016-2019, YLL due to unintentional overdose was the third leading cause of YLL overall for this population. CONCLUSIONS: Unintentional drug overdose is a leading cause of death for perinatal individuals in the United States, claiming nearly 84,000 years of life over a ten-year period. When examining by race, American Indian/Native American women are most disproportionately affected.

Fibromyalgia predicts increased odds of pain-related addiction exacerbation among individuals with pain and opioid use disorder.

ABSTRACT: Fibromyalgia and opioid use disorder (OUD) are highly impactful chronic illnesses with substantially overlapping psychosocial, biological, and clinical features. Little previous research has examined interactions between fibromyalgia and OUD. Limiting such research has been the previous requirement of a clinical examination to diagnose fibromyalgia. The 2011 American College of Rheumatology Fibromyalgia Survey (ACR-FMS) is a validated self-report instrument with high sensitivity and specificity for fibromyalgia intended to enable fibromyalgia research in settings where a clinical examination is impractical. The present observational study uses the ACR-FMS to determine whether fibromyalgia affects odds of acknowledging pain-related OUD exacerbations among a sample of participants with pain and OUD. Participants with pain and OUD (n = 125) were recruited from an academic substance use treatment facility. The ACR-FMS, along with an original scale measuring pain-related OUD exacerbation-the Pain-related OUD Exacerbation Scale-was administered through an electronic survey. The factor structure, internal consistency, and construct validity of Pain-related OUD Exacerbation Scale were tested. In addition, descriptive analyses, multiple hierarchical linear regression, ordinal logistic regression, and multinomial logistic regression analyses were performed. Although all participants had pain, those with fibromyalgia demonstrated significantly greater odds of acknowledging pain-related OUD exacerbations. Pain-related OUD Exacerbation Scale was found to have a single-factor solution, strong internal consistency, and construct validity. This study provides first evidence of fibromyalgia as a risk factor for pain-related exacerbation of OUD and introduces a new scale with promising psychometric properties to measure pain-related OUD exacerbation.

Years of life lost due to unintentional drug overdose relative to the leading underlying causes of death in the United States: a comparative analysis of excess mortality 2017-2019.

The present study aims to compare Years of Life Lost for unintentional drug overdose and the leading underlying causes of death in the United States annually from 2017 to 2019. Years of Life Lost provide valuable context to incident deaths when comparing the relative mortality burden of underlying causes of death. Prior research has shown unintentional drug overdose was the third leading cause of Years of Life Lost in the state of Ohio in 2017. However, this finding has yet to be replicated at the national level in the US. Death statistics for 2017-2019 were accessed via CDC WONDER. Years of Life Lost were calculated for unintentional drug overdose and each of the top five causes of incident deaths in the US during the study period. Unintentional drug overdose caused nearly seven million Years of Life Lost in the US during the three-year period of study and was the fourth leading cause of Years of Life Lost after cancer, heart disease and other accidents. Incidence alone provides an incomplete picture of the effect of unintentional drug overdose on overall mortality burden in the US. Years of Life Lost give critical context to the overdose crisis, underscoring unintentional drug overdose as a leading cause of premature mortality.
