Opioid Use Disorder and Employee Work Presenteeism, Absences, and Health Care Costs.

OBJECTIVE: To measure the prevalence of opioid use disorder (OUD) and employee health care and productivity costs with and without OUD and to assess whether utilization of pharmacotherapy for OUD reduces those costs. METHODS: We conducted a cross-sectional analysis of 2016 to 2017 commercial enrollment, health care, and pharmacy claims and health risk assessment data using the IBM MarketScan Databases (Ann Arbor, MI). We estimated regression models to assess the association between OUD and annual employee health care and productivity costs. RESULTS: Health care and productivity costs for employees with OUD who did and did not receive pharmacotherapy were approximately $6294 and $21,570 more than for other employees, respectively. CONCLUSIONS: Employers can make a business case for expanding access to pharmacotherapy treatment for OUD based on our finding that receipt of pharmacotherapy significantly reduces overall health care costs.

Patient factors contributing to variation in same-hospital readmission rate.

The Centers for Medicare & Medicaid Services Hospital Readmission Reduction Program and the Centers for Medicare & Medicaid Innovations Bundled Payments for Care Improvement Initiative hold hospitals accountable for readmissions that occur at other hospitals. A few studies have described the extent to which hospital readmissions occur at the original place of treatment (i.e., same-hospital readmissions). This study uses data from 16 states to describe variation in same-hospital readmissions by patient characteristics across multiple conditions. We found that the majority of 30-day readmissions occur at the same hospital, although rates varied considerably by condition. A significant number of hospitals had very low rates of same-hospital readmissions, meaning that the majority of their readmissions went to other hospitals. Future research should examine why some hospitals are able to retain patients for a same-hospital readmission and others are not.

National estimates of behavioral health conditions and their treatment among adults newly insured under the ACA.

OBJECTIVE: Approximately 25 million individuals are projected to gain insurance as a result of the Affordable Care Act (ACA). This study estimated the prevalence of behavioral health conditions and their treatment among individuals likely to gain coverage. METHODS: Pooled 2008-2011 National Survey on Drug Use and Health data for adults (ages 18-64) were used. Estimates were created for all adults, current Medicaid beneficiaries, and uninsured adults with incomes that might make them eligible for the Medicaid expansion or tax credits for use in the health insurance marketplace. RESULTS: Individuals who may gain insurance under the ACA had lower rates of serious mental illnesses (5.4%, Medicaid expansion; 4.7%, marketplace) compared with current Medicaid beneficiaries (9.6%). They had higher rates of substance use disorders (13.6%, Medicaid expansion; 14.3%, marketplace) compared with Medicaid recipients (11.9%). CONCLUSIONS: There is significant need for behavioral health treatment among individuals who may gain insurance under the ACA.

Geographic variation in cesarean delivery in the United States by payer.

BACKGROUND: The rate of cesarean delivery in the United States is variable across geographic areas. The aims of this study are two-fold: (1) to determine whether the geographic variation in cesarean delivery rate is consistent for private insurance and Medicaid (2) to identify the patient, population, and market factors associated with cesarean rate and determine if these factors vary by payer. METHODS: We used the Healthcare Cost and Utilization Project (HCUP) State Inpatient Databases (SID) to measure the cesarean rate at the Core-Based Statistical Area (CBSA) level. We linked the hospitalization data to data from other national sources to measure population and market characteristics. We calculated unadjusted and risk-adjusted CBSA cesarean rates by payer. For the second aim, we estimated a hierarchical logistical model with the hospitalization as the unit of analysis to determine the factors associated with cesarean delivery. RESULTS: The average CBSA cesarean rate for women with private insurance was higher (18.9 percent) than for women with Medicaid (16.4 percent). The factors predicting cesarean rate were largely consistent across payers, with the following exceptions: women under age 18 had a greater likelihood of cesarean section if they had Medicaid but had a greater likelihood of vaginal birth if they had private insurance; Asian and Native American women with private insurance had a greater likelihood of cesarean section but Asian and Native American women with Medicaid had a greater likelihood of vaginal birth. The percent African American in the population predicted increased cesarean rates for private insurance only; the number of acute care beds per capita predicted increased cesarean rate for women with Medicaid but not women with private insurance. Further we found the number of obstetricians/gynecologists per capita predicted increased cesarean rate for women with private insurance only, and the number of midwives per capita predicted increased vaginal birth rate for women with private insurance only. CONCLUSIONS: Factors associated with geographic variation in cesarean delivery, a frequent and high-resource inpatient procedure, vary somewhat by payer. Using this information to identify areas for intervention is key to improving quality of care and reducing healthcare costs.

High-resolution behavioral economic analysis of cigarette demand to inform tax policy.

AIMS: Novel methods in behavioral economics permit the systematic assessment of the relationship between cigarette consumption and price. Towards informing tax policy, the goals of this study were to conduct a high-resolution analysis of cigarette demand in a large sample of adult smokers and to use the data to estimate the effects of tax increases in 10 US States. DESIGN: In-person descriptive survey assessment. SETTING: Academic departments at three universities. PARTICIPANTS: Adult daily smokers (i.e. more than five cigarettes/day; 18+ years old; ≥8th grade education); n = 1056. MEASUREMENTS: Estimated cigarette demand, demographics, expired carbon monoxide. FINDINGS: The cigarette demand curve exhibited highly variable levels of price sensitivity, especially in the form of 'left-digit effects' (i.e. very high price sensitivity as pack prices transitioned from one whole number to the next; e.g. $5.80-6/pack). A $1 tax increase in the 10 states was projected to reduce the economic burden of smoking by an average of $530.6 million (range: $93.6-976.5 million) and increase gross tax revenue by an average of 162% (range: 114-247%). CONCLUSIONS: Tobacco price sensitivity is non-linear across the demand curve and in particular for pack-level left-digit price transitions. Tax increases in US states with similar price and tax rates to the sample are projected to result in substantial decreases in smoking-related costs and substantial increases in tax revenues.

The neuroeconomics of nicotine dependence: a preliminary functional magnetic resonance imaging study of delay discounting of monetary and cigarette rewards in smokers.

Neuroeconomics integrates behavioral economics and cognitive neuroscience to understand the neurobiological basis for normative and maladaptive decision making. Delay discounting is a behavioral economic index of impulsivity that reflects capacity to delay gratification and has been consistently associated with nicotine dependence. This preliminary study used functional magnetic resonance imaging to examine delay discounting for money and cigarette rewards in 13 nicotine dependent adults. Significant differences between preferences for smaller immediate rewards and larger delayed rewards were evident in a number of regions of interest (ROIs), including the medial prefrontal cortex, anterior insular cortex, middle temporal gyrus, middle frontal gyrus, and cingulate gyrus. Significant differences between money and cigarette rewards were generally lateralized, with cigarette choices associated with left hemisphere activation and money choices associated with right hemisphere activation. Specific ROI differences included the posterior parietal cortex, medial and middle frontal gyrus, ventral striatum, temporoparietal cortex, and angular gyrus. Impulsivity as measured by behavioral choices was significantly associated with both individual ROIs and a combined ROI model. These findings provide initial evidence in support of applying a neuroeconomic approach to understanding nicotine dependence.

Modernization and cardiometabolic risk in Samoan adolescents.

OBJECTIVE: To describe the prevalence of cardiometabolic risk factor clustering in Samoan adolescents and to relate risk factor clustering to weight status and general modernization. METHODS: Anthropometric and biochemical data collected from adolescents aged 12-17.9 years who participated in the Samoan Family Study of Overweight and Diabetes were used to describe the prevalence of cardiometabolic risk factors (high waist circumference, high blood pressure, high triglyceride level, low-high-density lipoprotein cholesterol, and high fasting serum glucose). A total of 436 adolescents were included in this analysis; 237 (54.4%) from American Samoa (n = 123 males) and 199 (45.6%) from Samoa (n = 90 males). Risk factor clustering was indicated by the presence of ≥ 3 risk factors. RESULTS: Cardiometabolic risk factor clustering was greater in American Samoan adolescents (17.9% males, 21.9% females) than Samoan adolescents (1.1% males, 2.8% females). The frequency of risk factor clustering varied according to body mass index status. In males, risk factor clustering was entirely confined to obese adolescents, whereas female adolescents who were overweight or obese were at risk. CONCLUSIONS: Cardiometabolic risk factor clustering is prevalent in the young American Samoan population and is likely to become more prevalent with increasing modernization in Samoan youth. Screening and intervention should be targeted at this age group to reduce the non-communicable disease burden faced by these populations.

Effect of robot-assisted versus conventional body-weight-supported treadmill training on quality of life for people with multiple sclerosis.

This study describes the effect of body-weight-supported treadmill training (BWSTT) on quality of life (QoL) for multiple sclerosis (MS) patients. Thirteen individuals with MS and gait impairment randomly received two blocks of six biweekly training sessions: (1) robot-assisted BWSTT then BWSTT alone (R-T) or (2) BWSTT alone then robot-assisted BWSTT (T-R). No statistically significant differences were found between robot-assisted BWSTT and unassisted BWSTT for improving QoL outcome measures. The change in Physical Component Summary scores from baseline to the end of the 12 training sessions improved significantly more in the R-T than the T-R group. Within-participant longitudinal changes in QoL for all participants from both groups combined showed significant improvements in 5 of the 13 QoL measures. The results of this pilot study suggest that both types of BWSTT may improve QoL for people with gait dysfunction secondary to MS.

Food safety education: child-to-parent instruction in an immigrant population.

A quasi-experimental pretest-posttest design was used to examine increases in food handling knowledge among eastern European refugee restaurant candidates as a result of educational material taught either by the employee's child or the Salt Lake Valley Health Department. Participants were nonrandomly assigned to a study (n = 15) or control group (n = 17). The study group was taught by their children in their native language. The control group was taught by an SLVHD instructor in English. All participants completed pre- and posttests that measured four areas of food handling knowledge: personal hygiene and hand washing (PHHW), cooking and holding time/temperature (COOKTT), cooling and holding time/temperature (COOLTT), and cross-contamination (CC). Both groups demonstrated a significant increase in knowledge of PHHW, but only the study group demonstrated significant improvements in COOKTT and CC knowledge. These study results suggest that food handling education programs are effective in increasing knowledge and mode of delivery may be an important factor.

Assessing consumer awareness about mercury in fish.

The study discussed in this article was conducted to determine if a retail-based educational campaign would be an effective tool to inform consumers about mercury in fish. In 2005, the Rhode Island (RI) Department of Health, in conjunction with the RI Food Dealers Association, conducted surveys in eight supermarkets to assess consumers' knowledge and awareness of mercury in fish. A presurvey was administered to 523 respondents as they prepared to exit the store June 17-19. During the week of July 11-17, a "Fish Week" educational program was conducted. An identical postsurvey to evaluate the effectiveness of "Fish Week" was administered to 556 customers exiting participating supermarkets on July 21-24. A significant (p < .05) increase occurred in the number of respondents who identified brochures as an information source about mercury in fish. Small, but significant, decreases in awareness and knowledge about mercury in fish issues, however, were unexpected findings that were likely due to factors discussed.

Childhood parental loss and adult psychopathology: effects of loss characteristics and contextual factors.

The purpose of this study was to determine whether childhood parental death and childhood parental separation are linked to lifetime depressive and anxiety disorders after controlling for related risk factors. Participants were 105 individuals from the community, including a group with separation/desertion from a parent, a group with childhood parental death, and a matched control group whose parents remained married and living together. Participants completed interviews and questionnaires assessing symptoms of anxiety and depression, family psychiatric history, childhood maltreatment, and childhood parental relationships. Participants with separation/desertion and those with parental death were significantly more likely than the control subjects to report the subsequent onset of symptoms of a depressive or anxiety disorder. These effects were not fully explained by parental relationships or childhood maltreatment. However, in the group with parental separation only, family history of depressive and anxiety disorders accounted for the apparent effect of parental separation. These findings indicate that parental death may be a specific risk factor for depressive and anxiety disorders. For parental separation/desertion, our results highlight the overriding influence of risk factors that commonly co-occur with this form of parental loss.

Childhood parental loss and adult hypothalamic-pituitary-adrenal function.

BACKGROUND: Several decades of research link childhood parental loss with risk for major depression and other forms of psychopathology. A large body of preclinical work on maternal separation and some recent studies of humans with childhood parental loss have demonstrated alterations of hypothalamic-pituitary-adrenal (HPA) axis function that could predispose to the development of psychiatric disorders. METHODS: Eighty-eight healthy adults with no current Axis I psychiatric disorder participated in this study. Forty-four participants experienced parental loss during childhood, including 19 with a history of parental death and 25 with a history of prolonged parental separation. The loss group was compared with a matched group of individuals who reported no history of childhood parental separation or childhood maltreatment. Participants completed diagnostic interviews and questionnaires and the dexamethasone/corticotropin-releasing hormone (Dex/CRH) test. Repeated measures general linear models were used to test the effects of parental loss, parental care, gender, and age on the hormone responses to the Dex/CRH test. RESULTS: Parental loss was associated with increased cortisol responses to the test, particularly in men. The effect of loss was moderated by levels of parental care; participants with parental desertion and very low levels of care had attenuated cortisol responses. Adrenocorticotropic hormone responses to the Dex/CRH test did not differ significantly as a function of parental loss. CONCLUSIONS: These findings are consistent with the hypothesis that early parental loss induces enduring changes in neuroendocrine function.

Cortisol and ACTH responses to the Dex/CRH test: influence of temperament.

Temperament and personality traits such as neuroticism and behavioral inhibition are prospective predictors of the onset of depression and anxiety disorders. Exposure to stress is also linked to the development of these disorders, and neuroticism and inhibition may confer or reflect sensitivity to stressors. Several lines of research have documented hyperactivity of the hypothalamic-pituitary-adrenal (HPA) axis in some patients with major depression, as well as in children and non-human primates with inhibited temperaments. The present investigation tested the hypothesis that stress-reactive temperaments would be predictive of plasma adrenocorticotropin (ACTH) and cortisol concentrations in the dexamethasone/corticotropin-releasing hormone (Dex/CRH) test. Sixty adults completed diagnostic interviews and questionnaires assessing the temperament domains of novelty seeking and harm avoidance and symptoms of anxiety and depression. All subjects were free of any current or past Axis I psychiatric disorder. The Dex/CRH test was performed on a separate visit. A repeated-measures general linear model (GLM) showed a main effect of harm avoidance in predicting cortisol concentrations in the test (F(1, 58)=4.86, p<.05). The GLM for novelty seeking and cortisol response also showed a main effect (F(1, 58)=5.28, p<.05). Higher cortisol concentrations were associated with higher levels of harm avoidance and lower levels of novelty seeking. A significant interaction of time with harm avoidance and novelty seeking (F(4, 53)=3.37, p<.05) revealed that participants with both high levels of harm avoidance and low levels of novelty seeking had the highest cortisol responses to the Dex/CRH test. Plasma ACTH concentrations did not differ as a function of temperament. The results indicate that temperament traits linked to sensitivity to negative stimuli are associated with greater cortisol reactivity during the Dex/CRH test. Increased adrenocortical reactivity, which previously has been linked to major depression and anxiety disorders, may contribute to the association between temperament/personality traits and these disorders.

Decreased adrenocorticotropic hormone and cortisol responses to stress in healthy adults reporting significant childhood maltreatment.

BACKGROUND: Preclinical research findings suggest that exposure to stress and concomitant hypothalamus-pituitary-adrenal (HPA) axis activation during early development can have permanent and potentially deleterious effects. A history of early-life abuse or neglect appears to increase risk for mood and anxiety disorders. Abnormal HPA response to stress challenge has been reported in adult patients with major depressive disorder and posttraumatic stress disorder. METHODS: Plasma adrenocorticotropin hormone (ACTH) and cortisol reactivity to the Trier Social Stress Test were examined in healthy adults (n = 50) without current psychopathology. Subjects with a self-reported history of moderate to severe childhood maltreatment (MAL) (n = 23) as measured by the Childhood Trauma Questionnaire were compared with subjects without such a history (CTL) (n = 27). RESULTS: Compared with CTLs, MAL subjects exhibited significantly lower cortisol and ACTH baseline-to-peak deltas. A significant group effect was seen in the (repeated measures) cortisol response to the stress challenge, reflecting lower concentrations among MAL subjects. A significant group x time effect characterized the relatively blunted ACTH response of the MAL group. Emotional neglect (-.34, p = .02) and sexual abuse (.31, p = .03) strongly predicted maximal cortisol release. CONCLUSIONS: In adults without diagnosable psychopathology, childhood maltreatment is associated with diminished HPA axis response to a psychosocial stressor. Possible explanations for the finding are discussed.
