A social gradient in fatal opioids and cocaine related overdoses?

Laboratory method to induce state boredom increases impulsive choice in people who use cocaine and controls

Background: Impulsive choice is associated with both cocaine use and relapse. Little is known about the influence of transient states on impulsive choice in people who use cocaine (PWUC).Objective: This study investigated the direct effects of induced boredom on impulsive choice (i.e., temporal discounting) in PWUC relative to well-matched community controls.Methods: Forty-one PWUC (≥1× cocaine use in past 3 months; 7 females) and 38 demographically matched controls (5 females) underwent two experimental conditions in counterbalanced order. Temporal discounting was assessed immediately after a standardized boredom induction task (peg-turning) and a self-selected video watched for the same duration (non-boredom). Subjective mood state and perceived task characteristics were assessed at baseline, during experimental manipulations, and after the choice task.Results: PWUC and controls were well matched on sex, age, and socioeconomic status. Groups were also similar in reported use of drugs other than cocaine, except for recent cigarette and alcohol use (PWUC > controls). As expected, peg-turning increased boredom in the sample overall, with higher boredom reported during peg-turning than the video (p < .001, η2p = .20). Participants overall exhibited greater impulsive choice after boredom than non-boredom (p = .028, η2p = .07), with no preferential effects in PWUC (p > .05, BF01 = 2.9).Conclusion: Experimentally induced boredom increased state impulsivity irrespective of cocaine use status - in PWUC and carefully matched controls - suggesting a broad link between boredom and impulsive choice. This is the first study to show that transient boredom directly increases impulsive choice. Data support a viable laboratory method to further parse the effects of boredom on impulsive choice.

Short communication: Relationship between social determinants and opioid use disorder treatment outcomes by gender

BACKGROUND

Social determinants of health (SDoH) influence health outcomes differentially across gender. Gender differences in SDoH have been identified at baseline in opioid use disorder (OUD) treatment studies, but less is known about how SDoH and gender intersect with OUD treatment trajectories. This study aims to identify social correlates of OUD treatment outcomes from five key areas of social determinants separately for men and women receiving buprenorphine for OUD.

METHODS

This is a secondary data analysis of a cross-sectional survey with medical record review conducted with patients recruited from an office based opioid treatment clinic. Participants completed surveys between July-September 2019. A 6-month prospective medical record review was conducted to determine treatment retention, substance use recurrence, and buprenorphine continuation. Chi square, T-tests, and Mann Whitney U tested differences in social factors and OUD outcomes by gender. Gender-stratified multivariable logistic and negative binomial regressions assessed predictors of OUD outcomes.

RESULTS

Among study participants (n = 142), women were significantly younger (p < 0.001), more likely to live in a safe neighborhood (p = 0.046), and less likely to be employed (p = 0.005) or have substance use recurrence during the study period (p = 0.033) than men. For women, employment (AOR=0.19, p = 0.031) and education (AOR=0.08, p = 0.040) were negatively associated with treatment retention. For men, no social factors were associated with OUD outcomes.

CONCLUSIONS

SDoH may impact OUD treatment outcomes differently by gender. Addressing MOUD stigma and implementing patient-centered care strategies may facilitate OUD treatment continuation among employed women in recovery. Gender-related social factors should be considered in OUD treatment research.

Social Determinants of Opioid Use among Patients in Rural Primary Care Settings

Opioid use and misuse are a widespread problem across the United States. Identifying and targeting social determinants of opioid use may help to identify predictive factors to influence intervention and policy. The purpose of this study was to identify social determinants of opioid use frequency among patients seeking primary care in rural Alabama healthcare facilities. This survey-based study focused on a patient population located in rural west Alabama surveyed for a screening, brief intervention, and referral to treatment program. The screening tool contained demographic information and questions regarding the social determinants of health and opioid use, among others. Adjusted incidence rate ratios (IRRs) for the relationship between social determinants of health and opioid use frequency (in days/month) were estimated in Poisson regression models. Eleven percent of the population self-reported opioid use in the past 30 days. Three social determinants of health measured (level of education, housing stability, and employment status) were identified as having a significant association with the frequency of opioid use. Targeting certain social determinants of health may allow for further predictive interventions to mitigate opioid misuse and potential fatality or mortality.

Addressing substance use disorder in primary care: The role, integration, and impact of recovery coaches

BACKGROUND

Only 10% of people with substance use disorder (SUD) receive treatment, partially due to inadequate access to specialty SUD care and limited management within primary care. "Recovery coaches" (RCs), peers sharing the lived experience of addiction and recovery, are increasingly being integrated into primary care to help reach and treat people experiencing SUD, yet little is known about how their role should be defined or about their clinical integration and impact.

METHODS

Semistructured interviews with RCs (n = 5) and their patients (n = 16) were used to explore patient and RC perspectives on the RC role. Maximum variation sampling was employed to select patients who displayed diversity across gender, RC, housing status, and number of contacts with an RC. Patients were sampled until no new concepts emerged from additional interviews, and a semistructured interview guide was used for data collection. To analyze interview transcripts, the constant comparative method was used to develop and assign inductively developed codes. Two coders separately coded all transcripts and reconciled code assignments.

RESULTS

Four core RC activities were identified: system navigation, supporting behavior change, harm reduction, and relationship building. Across these activities, benefits of the RC role emerged, including accessibility, shared experiences, motivation of behavior change, and links to social services. Challenges of the RC model were also evident: patient discomfort with asking for help, lack of clarity in RC role, and tension within the care team.

CONCLUSIONS

These findings shed light on RCs in primary care. Many patients and coaches perceived that RCs play a valuable role within primary care, providing both tangible system navigation and intangible, social support that promote recovery and might not otherwise be available. Enhanced communication between RCs and health center leadership in defining the RC role may help resolve ambiguity and related tensions between RCs and care team members.

Patterns of analgesic use to relieve tooth pain among residents in British Columbia, Canada

The use of prescription opioids has increased dramatically in Canada in recent decades. This rise in opioid prescriptions has been accompanied by increasing rates of opioid-related abuse and addiction, creating serious public health challenges in British Columbia (BC), one of Canada's most populated provinces. Our study explores the relationship between dental pain and prescription opioid use among residents in BC. We used data from the 2003 Canadian Community Health Survey (CCHS), which asked respondents about their use of specific analgesic medications, including opioids, and their history of tooth pain in the past month. We used logistic regression, controlling for potential confounding variables, to identify the predictive value of socioeconomic factors, oral health-related variables, and dental care utilization indicators. The Relative Index of Inequality (RII) was calculated to assess the magnitude of socioeconomic inequalities in the use of particular analgesics by incorporating income-derived ridit values into a binary logistic regression model. Our results showed that conventional non-opioid based analgesics (such as aspirin or Tylenol) and opioids were more likely to be used by those who had experienced a toothache in the past month than those who did not report experiencing a toothache. The use of non-opioid painkillers to relieve tooth pain was associated with more recent and more frequent dental visits, better self-reported oral health, and a greater income. Conversely, a lower household income was associated with a preference for opioid use to relieve tooth pain. The RII for recent opioid use and conventional painkiller use were 2.06 (95% CI: 1.75-2.37) and 0.62 (95% CI: 0.35-0.91), respectively, among those who experienced recent tooth pain, suggesting that adverse socioeconomic conditions may influence the need for opioid analgesics to relieve dental pain. We conclude that programs and policies targeted at improving the dental health of the poor may help to reduce the use of prescription opioids, thereby narrowing health inequalities within the broader society.

Socioeconomic gradients in general and oral health of primary school children in Shiraz, Iran

Background: Health status is largely determined by socio-economic status. The general health of individuals at higher social hierarchy is better than people in lower levels. Likewise, people with higher socio-economic status have better oral health than lower socio-economic groups. There has not been much work regarding the influence of socio-economic status on the health conditions of children in developing countries, particularly in Iran. The aim of this study was to compare the oral and general health conditions of primary school children of three different socio-economic areas in the city of Shiraz, Iran.

Methods: This cross-sectional study was conducted on 335, 8- to 11-year-old primary schoolchildren in Shiraz. The children were selected by a three-stage cluster sampling method from three socio-economically different areas. Tools and methods used by the United Kingdom’s Medical Research Council were used to obtain anthropometric variables as indicators of general health. The Decay, Missing, Filled Teeth (DMFT) Index for permanent teeth, dmft Index for primary teeth, the Modified Developmental Defects of Enamel (DDE) Index, the Gingival Index (GI) and the Debris Index-Simplified (DI-S) were used for oral health assessment. 

Results: Height (P<0.001), weight (P<0.001), and BMI (P=0.001) significantly increased as the socio-economic status of area increased. GI score (P<0.001), DI-S score (P<0.001), number of permanent teeth with DDE (P=0.008), and number of DDE lesions in permanent teeth (P=0.008) significantly decreased as the socio-economic status of area increased.

Discussion: Findings of this study generally confirmed that social gradients exist in both general and oral health status of the primary schoolchildren of Shiraz. The influence of socio-economic status on health condition means children have different life chances based on their socio-economic conditions. These findings emphasize the significance of interventions for tackling socio-economic inequalities in order to improve the health status of children in lower socio-economic areas.
