The predictive validity of the progress assessment, a clinician administered instrument for use in measurement-based care for substance use disorders.

We tested the predictive validity of the Progress Assessment (PA), a brief counselor administered tool for use in measurement-based care for substance use disorders. The PA includes 5 items assessing relapse risk and 5 items assessing factors protective against relapse. Data were drawn from a completed study of continuing care for cocaine dependence (McKay et al., 2013) and includes 12 months of follow-up on158 participants (76% male) who received brief telephone or face-to-face sessions. Each session began with the administration of the PA, followed by cognitive-behavioral counseling tied to the results of the PA and anticipated risky situations. Outcome was assessed via urine toxicology every 3 months. As administered in an effectiveness trial, average PA risk and protective scales within each 3-month segment of the study predicted urine toxicology results at the end of that period, with higher risk scores and lower protective scores predicting greater rates of cocaine positive urine drug screens. PA scores did not predict dropout from continuing care participation. The 10-item PA shows promise as a pragmatic clinical tool for ongoing monitoring during continuing care for substance dependence.

Effects of automated smartphone mobile recovery support and telephone continuing care in the treatment of alcohol use disorder: study protocol for a randomized controlled trial.

BACKGROUND: New smartphone communication technology provides a novel way to provide personalized continuing care support following alcohol treatment. One such system is the Addiction version of the Comprehensive Health Enhancement Support System (A-CHESS), which provides a range of automated functions that support patients. A-CHESS improved drinking outcomes over standard continuing care when provided to patients leaving inpatient treatment. Effective continuing care can also be delivered via telephone calls with a counselor. Telephone Monitoring and Counseling (TMC) has demonstrated efficacy in two randomized trials with alcohol-dependent patients. A-CHESS and TMC have complementary strengths. A-CHESS provides automated 24/7 recovery support services and frequent assessment of symptoms and status, but does not involve regular contact with a counselor. TMC provides regular and sustained contact with the same counselor, but no ongoing support between calls. The future of continuing care for alcohol use disorders is likely to involve automated mobile technology and counselor contact, but little is known about how best to integrate these services. METHODS/DESIGN: To address this question, the study will feature a 2 × 2 design (A-CHESS for 12 months [yes/no] × TMC for 12 months [yes/no]), in which 280 alcohol-dependent patients in intensive outpatient programs (IOPs) will be randomized to one of the four conditions and followed for 18 months. We will determine whether adding TMC to A-CHESS produces fewer heavy drinking days than TMC or A-CHESS alone and test for TMC and A-CHESS main effects. We will determine the costs of each of the four conditions and the incremental cost-effectiveness of the three active conditions. Analyses will also examine secondary outcomes, including a biological measure of alcohol use, and hypothesized moderation and mediation effects. DISCUSSION: The results of the study will yield important information on improving patient alcohol use outcomes by integrating mobile automated recovery support and counselor contact.

Family Characteristics Associated With Child Maltreatment Across the Deployment Cycle of U.S. Army Soldiers.

OBJECTIVE: Soldier deployment can create a stressful environment for U.S. Army families with young children. Prior research has identified elevated rates of child maltreatment in the 6 months immediately following a soldier's return home from deployment. In this study, we longitudinally examine how other child- and family-level characteristics influence the relationship of deployment to risk for maltreatment of dependent children of U.S. Army soldiers. METHODS: We conducted a person-time analysis of substantiated reports and medical diagnoses of maltreatment among the 73,404 children of 56,087 U.S. Army soldiers with a single deployment between 2001 and 2007. Cox proportional hazard models estimated hazard rates of maltreatment across deployment periods and simultaneously considered main effects for other child- and family-level characteristics across periods. RESULTS: In adjusted models, maltreatment hazard was highest in the 6 months following deployment (hazard ratio [HR] = 1.63, p < 0.001). Children born prematurely or with early special needs independently had an increased risk for maltreatment across all periods (HR = 2.02, p < 0.001), as well as those children whose soldier-parent had been previously diagnosed with a mental illness (HR = 1.68, p < 0.001). In models testing for effect modification, during the 6 months before deployment, children of female soldiers (HR = 2.22, p = 0.006) as well as children of soldiers with a mental health diagnosis (HR = 2.78, p = 0.001) were more likely to experience maltreatment, exceeding the risk at all other periods. CONCLUSIONS: Infants and children are at increased risk for maltreatment in the 6 months following a parent's deployment, even after accounting for other known family- and child-level risk factors. However, the risk does not appear to be the same for all soldiers and their families in relation to deployment, particularly for female soldiers and those who had previously diagnosed mental health issues, for whom the risk appears most elevated before deployment. Accounting for the unique needs of high-risk families at different stages of a soldier's deployment cycle may allow the U.S. Army to better direct resources that prevent and address child maltreatment.

Under-ascertainment from healthcare settings of child abuse events among children of soldiers by the U.S. Army Family Advocacy Program.

In cases of maltreatment involving children of U.S. Army service members, the U.S. Army Family Advocacy Program (FAP) is responsible for providing services to families and ensuring child safety. The percentage of cases of maltreatment that are known to FAP, however, is uncertain. Thus, the objective of this retrospective study was to estimate the percentage of U.S. Army dependent children with child maltreatment as diagnosed by a military or civilian medical provider who had a substantiated report with FAP from 2004 to 2007. Medical claims data were used to identify 0-17year old child dependents of soldiers who received a medical diagnosis of child maltreatment. Linkage rates of maltreatment medical diagnoses with corresponding substantiated FAP reports were calculated. Bivariate and multivariable analyses examined the association of child, maltreatment episode, and soldier characteristics with linkage to substantiated FAP reports. Across 5945 medically diagnosed maltreatment episodes, 20.3% had a substantiated FAP report. Adjusting for covariates, the predicted probability of linkage to a substantiated FAP report was higher for physical abuse than for sexual abuse, 25.8%, 95% CI (23.4, 28.3) versus 14.5%, 95% CI (11.2, 17.9). Episodes in which early care was provided at civilian treatment facilities were less likely to have a FAP report than those treated at military facilities, 9.8%, 95% CI (7.3, 12.2) versus 23.6%, 95% CI (20.8, 26.4). The observed low rates of linkage of medically diagnosed child maltreatment to substantiated FAP reports may signal the need for further regulation of FAP reporting requirements, particularly for children treated at civilian facilities.

A randomized clinical trial of alcohol care management delivered in Department of Veterans Affairs primary care clinics versus specialty addiction treatment.

BACKGROUND: Alcohol use disorder is one of the leading causes of disability worldwide. Despite the availability of efficacious treatments, few individuals with an alcohol use disorder are actively engaged in treatment. Available evidence suggests that primary care may play a crucial role in the identification of patients with an alcohol use disorder, delivery of interventions, and the success of treatment. OBJECTIVE: The principal aims of this study were to test the effectiveness of a primary care-based Alcohol Care Management (ACM) program for alcohol use disorder and treatment engagement in veterans. DESIGN: The design of the study was a 26-week single-blind randomized clinical trial. The study was conducted in the primary care practices at three VA medical centers. Participants were randomly assigned to treatment in ACM or standard treatment in a specialty outpatient addiction treatment program. PARTICIPANTS: One hundred and sixty-three alcohol-dependent veterans were randomized. INTERVENTION: ACM focused on the use of pharmacotherapy and psychosocial support. ACM was delivered in-person or by telephone within the primary care clinic. MAIN MEASUREMENTS: Engagement in treatment and heavy alcohol consumption. KEY RESULTS: The ACM condition had a significantly higher proportion of participants engaged in treatment over the 26 weeks [OR = 5.36, 95 % CI = (2.99, 9.59)]. The percentage of heavy drinking days were significantly lower in the ACM condition [OR = 2.16, 95 % CI = (1.27, 3.66)], while overall abstinence did not differ between groups. CONCLUSIONS: Results demonstrate that treatment for an alcohol use disorder can be delivered effectively within primary care, leading to greater rates of engagement in treatment and greater reductions in heavy drinking.

Bayesian multivariate growth curve latent class models for mixed outcomes.

In many clinical studies, the disease of interest is multifaceted, and multiple outcomes are needed to adequately capture information about the characteristics of the disease or its severity. In the analysis of such diseases, it is often difficult to determine what constitutes improvement because of the multivariate nature of the outcome. Furthermore, when the disease of interest has an unknown etiology and/or is primarily a symptom-defined syndrome, there is potential for the disease population to have distinct subgroups. Identification of population subgroups is of interest as it may assist clinicians in providing appropriate treatment or in developing accurate prognoses. We propose multivariate growth curve latent class models that group subjects on the basis of multiple symptoms measured repeatedly over time. These groups or latent classes are defined by distinctive longitudinal profiles of a latent variable, which is used to summarize the multivariate outcomes at each point. The mean growth curve for the latent variable in each class defines the features of the class. We develop this model for any combination of continuous, binary, ordinal, or count outcomes within a Bayesian hierarchical framework. We use simulation studies to validate the estimation procedures. We apply our model to data from a randomized clinical trial evaluating the efficacy of Bacillus Calmette-Guerin in treating symptoms of interstitial cystitis where we are able to identify a class of subjects for whom treatment is effective.

An adaptive approach for identifying cocaine dependent patients who benefit from extended continuing care.

OBJECTIVE: Study tested whether cocaine dependent patients using cocaine or alcohol at intake or in the first few weeks of intensive outpatient treatment would benefit more from extended continuing care than patients abstinent during this period. The effect of incentives for continuing care attendance was also examined. METHOD: Participants (N = 321) were randomized to treatment as usual (TAU), TAU and telephone monitoring and counseling (TMC), or TAU and TMC plus incentives (TMC+). The primary outcomes were (a) abstinence from all drugs and heavy alcohol use and (b) cocaine urine toxicology. Follow-ups were at 3, 6, 9, 12, 18, and 24 months. RESULTS: Cocaine and alcohol use at intake or early in treatment predicted worse outcomes on both measures (ps ≤ .0002). Significant effects favoring TMC over TAU on the abstinence composite were obtained in participants who used cocaine (odds ratio [OR] = 1.95 [1.02, 3.73]) or alcohol (OR = 2.47 [1.28, 4.78]) at intake or early in treatment. A significant effect favoring TMC+ over TAU on cocaine urine toxicology was obtained in those using cocaine during that period (OR = 0.55 [0.31, 0.95]). Conversely, there were no treatment effects in participants abstinent at baseline and no overall treatment main effects. Incentives almost doubled the number of continuing care sessions received but did not further improve outcomes. CONCLUSION: An adaptive approach for cocaine dependence in which extended continuing care is provided only to patients who are using cocaine or alcohol at intake or early in treatment improves outcomes in this group while reducing burden and costs in lower risk patients.

Content matters: neuroimaging investigation of brain and behavioral impact of televised anti-tobacco public service announcements.

Televised public service announcements are video ads that are a key component of public health campaigns against smoking. Understanding the neurophysiological correlates of anti-tobacco ads is an important step toward novel objective methods of their evaluation and design. In the present study, we used functional magnetic resonance imaging (fMRI) to investigate the brain and behavioral effects of the interaction between content ("argument strength," AS) and format ("message sensation value," MSV) of anti-smoking ads in humans. Seventy-one nontreatment-seeking smokers viewed a sequence of 16 high or 16 low AS ads during an fMRI scan. Dependent variables were brain fMRI signal, the immediate recall of the ads, the immediate change in intentions to quit smoking, and the urine levels of a major nicotine metabolite cotinine at a 1 month follow-up. Whole-brain ANOVA revealed that AS and MSV interacted in the inferior frontal, inferior parietal, and fusiform gyri; the precuneus; and the dorsomedial prefrontal cortex (dMPFC). Regression analysis showed that the activation in the dMPFC predicted the urine cotinine levels 1 month later. These results characterize the key brain regions engaged in the processing of persuasive communications and suggest that brain fMRI response to anti-smoking ads could predict subsequent smoking severity in nontreatment-seeking smokers. Our findings demonstrate the importance of the quality of content for objective ad outcomes and suggest that fMRI investigation may aid the prerelease evaluation of televised public health ads.

Performance contracting to engage detoxification-only patients into continued rehabilitation.

In 2006, only 18.7% of Delaware's detoxification patients were admitted to continuing recovery-oriented treatment within 30 days after discharge. In response, Delaware established financial contingencies to (1) maintain 90% detoxification occupancy, (2) make receipt of 10% of the facility's monthly reimbursement contingent on 25% of patients entering treatment, and (3) provide a $500 bonus for every patient with three or more prior detoxification visits who was retained in treatment. Under the performance contract, the detoxification provider (1) maintained the 90% occupancy requirement, (2) achieved the 25% treatment entry target for 7 of 12 months, and (3) observed only 8% (27/337) of detoxification completions that met the targeted length of stay. Continuation to and retention in treatment was even more constrained for patients with three or more prior detoxifications. Contrary to the policy intent, the number of patients with three or more detoxifications in fiscal year (FY) 2008 is nearly triple that of FY 2006. The modest gain in the transition rate was achieved without changes in patient access; the FY 2008 patient population reported significantly higher rates of homelessness and a younger age of first use than before the performance contract in FY 2006. Performance contracting may offer promise for improving transition to treatment rates. However, the unique needs of detoxification patients, the treatment capacity of each level of care to meet patient needs, and the structure of the performance contract must be carefully considered. Performance contracting efforts may be strengthened when service contracts across the system are tightly synchronized.

The GABA B agonist baclofen reduces cigarette consumption in a preliminary double-blind placebo-controlled smoking reduction study.

The surge in dopamine in ventral striatal regions in response to drugs of abuse and drug-associated stimuli is a final common pathway of addiction processes. GABA B agonists exert their effects indirectly, by quieting dopaminergic afferents. The ability of the GABA B agonist, baclofen to ameliorate nicotine and drug motivated behavior is established within the animal literature, however its potential to do so in humans is understudied, particularly with respect to its possible utility as a smoking cessation agent. We conducted a nine-week double-blind placebo-controlled pilot trial of baclofen for smoking reduction (N=30/group) in smokers contemplating, but not quite ready to quit. Baclofen was titrated upwards to 20mg q.i.d. over a period of twelve days. The primary outcome measure was the number of cigarettes smoked per day (CPD). A significant group by time effect of medication was observed. Baclofen was superior to placebo in reducing CPD (beta=0.01, t=1.97, p<0.05). The most common side effect reported during baclofen treatment is transient drowsiness, however there were no differences between groups in mild, moderate, or severe sedation. Craving was significantly lowered at end of treatment in all smokers (p<0.02). Retention did not differ between groups. In line with a multitude of preclinical studies examining the effects of baclofen on drug-motivated behavior, baclofen reduced CPD. In agreement with other studies examining craving and drug use, reductions in CPD were accompanied by a reduction in craving, a major motivator underlying continued smoking and relapse. These preliminary results demonstrate provisional evidence of the utility of baclofen to aid in smoking cessation and indicate further investigation.

Individual characteristics of the literally homeless, marginally housed, and impoverished in a US substance abuse treatment-seeking sample.

BACKGROUND: Many researchers and clinicians believe that understanding substance use problems is key to understanding homelessness. This study's purpose was to test, in a national sample of urban substance abuse treatment seekers, whether (1) income was related to amount of money spent on substances and (2) homeless chronic substance users had more severe psychosocial problems or histories than housed chronic substance users. METHOD: Questions assessing homelessness were inserted into the Drug Evaluation Network System-a computer-assisted intake interview (including the Addiction Severity Index) implemented in addiction treatment programs across the U.S. Based on these data, clients were divided into four residential groups: literally homeless (n = 654), marginally housed (n = 1138), housed poor (n = 3119), and housed not poor (n = 718). Income, human capital (education level and acquisition of a trade/skill), substance use, mental health, and social support were examined. RESULTS: The literally homeless was not the poorest group, although these clients did spend the most money on substances. All four groups' incomes were positively related to amount of money spent on drugs, but only the marginally housed's income was related to money spent on alcohol. The literally homeless had the most severe alcohol, mental health, and social support problems. The literally homeless and marginally housed had similar incomes and human capital and the most severe cocaine problems. In general the housed poor and housed not poor fared better than the literally homeless and marginally housed groups. DISCUSSION: Practitioners should continue to intervene with the homeless and consider working with the marginally housed's social support systems. Future research should examine the marginally housed as an at-risk group for homelessness.

Prescription OxyContin abuse among patients entering addiction treatment.

OBJECTIVE: OxyContin and other pharmaceutical opioids have been given special attention in the media, who frequently describe problematic users of the drug as previously drug-naive individuals who become addicted following legitimate prescriptions for medical reasons. The purpose of this study was to characterize the nature and origins of pharmaceutical opioid addiction among patients presenting at substance abuse treatment programs. METHOD: The authors evaluated the prevalence and correlates of OxyContin use and abuse among a population of 27,816 subjects admitted to 157 addiction treatment programs in the United States from 2001-2004. The data collected included the lifetime and past 30-day use of OxyContin and other drugs prior to admission to addiction treatment, source of drug supply, and prior treatment history. RESULTS: Approximately 5% of all subjects who were admitted to the 157 addiction treatment programs reported prior use of OxyContin. Of those subjects, 4.5% reported using the drug on a regular basis for at least 1 year, and 2% reported use of the drug during the 30 days prior to admission. Seventy-eight percent of subjects who reported OxyContin use also reported that the drug had not been prescribed to them for any medical reason, 86% reported use of the drug to "get high or get a buzz," and 78% reported receiving prior treatment for a substance use disorder. CONCLUSIONS: The patients in this sample did not include individuals from private therapists or pain clinics. However, among treatment-seeking individuals who use OxyContin, the drug is most frequently obtained from nonmedical sources as part of a broader and longer-term pattern of multiple substance abuse.

The availability of web sites offering to sell opioid medications without prescriptions.

OBJECTIVE: This study was designed to determine the availability of web sites offering to sell opioid medications without prescriptions. METHOD: Forty-seven Internet searches were conducted with a variety of opioid medication terms, including "codeine," "no prescription Vicodin," and "OxyContin." Two independent raters examined the links generated in each search and resolved any coding disagreements. The resulting links were coded as "no prescription web sites" (NPWs) if they offered to sell opioid medications without prescriptions. RESULTS: In searches with terms such as "no prescription codeine" and "Vicodin," over 50% of the links obtained were coded as "NPWs." The proportion of links yielding NPWs was greater when the phrase "no prescription" was added to the opioid term. More than 300 opioid NPWs were identified and entered into a database. CONCLUSIONS: Three national drug-use monitoring studies have cited significant increases in prescription opioid use over the past 5 years, particularly among young people. The emergence of NPWs introduces a new vector for unregulated access to opioids. Research is needed to determine the effect of NPWs on prescription opioid use initiation, misuse, and dependence.

Multidimensional assessment of nicotine dependence in adolescents.

Despite the critical importance of adolescent smoking, the assessment of nicotine dependence during this developmental period has been the subject of relatively little research. In this study, 301 adolescents (ages 12 through 18 years) reporting daily smoking were recruited for a project on alcohol use disorders (AUDs). The sample included 140 females and 161 males, 251 subjects from clinical and 50 from community sources, and 176 subjects with AUDs at the baseline assessment. Subjects were evaluated with the Nicotine Dependence Syndrome Scale (NDSS), the Fagerstrom Test for Nicotine Dependence (FTND) and a determination of average number of cigarettes per day (cigarettes/day). A varimax factor analysis of 27 NDSS items revealed four factors: (1) Drive/Tolerance (13 items; Cronbach alpha = 0.91); (2) Continuity (five items; Cronbach alpha = 0.67); (3) Priority (three items; Cronbach alpha = 0.64); (4) Stereotypy (five items; Cronbach alpha = 0.66). The NDSS total score, refined by the removal of four items, was also examined (23 items; Cronbach alpha = 0.90). Predicting cigarettes/day at follow-up, initial smoking rate was the best predictor, with the FTND and NDSS Total score showing significant and similar predictive validity. The NDSS Total showed incremental validity in the prediction of smoking progression in a model including demographic characteristics, initial smoking rate and FTND. The findings suggest that the NDSS has acceptable psychometric properties when applied to adolescents, complementing smoking rate and FTND in a multidimensional smoking assessment.

Effects of an intensive street-level police intervention on syringe exchange program use in Philadelphia, PA.

Repeated measurements and mixed-effects models were used to analyze the effects of an intensive long-term street-level police intervention on syringe exchange program use. Utilization data for 9 months before and after the beginning of the intervention were analyzed. Use fell across all categories and time periods studied, with significant declines in use among total participants, male participants, and Black participants. Declines in use among Black and male participants were much more pronounced than decreases among White and female participants.

Racial disparities in hospitalized elderly patients with chronic heart failure.

The purpose of this study was to examine the impact of race on length of hospital stay (LOS) and number of procedures on elderly persons hospitalized with chronic heart failure (CHF). Secondary data analysis was used to obtain data on 99,543 hospitalized Medicare patients with CHF age 65 years or older. MANOVA was utilized to examine the effects of race, age, and total hospital charges on LOS, number of procedures, and diagnosis. Asian American Pacific Islanders had significantly higher number of procedures and LOS compared to Whites. The combined dependent variables were significantly affected by race, F(9, 99,543) = 121.95, p =.000; the covariates of age, F(3, 99,543) = 720.65, p =.000; and total charges F(3, 99,543) = 38,962.95, p =.000. LOS accounted for 50% of the variance. Studies that examine cultural variables and their effect on LOS and number of procedures are needed.
