Burden of medical illness in drug- and alcohol-dependent persons without primary care

The Spanish language version of the TAPS tool: protocol for a validation and implementation study in primary care

BACKGROUND

The TAPS Tool ("Tobacco, Alcohol, Prescription drug, and illicit Substance use") is a screening and brief assessment for detecting unhealthy substance use in healthcare settings that was developed by the National Institute on Drug Abuse Clinical Trials Network and validated in a multisite study. Our team developed a Spanish language version of the TAPS Tool that supports provider- and self-administration screening using a mobile/web-based platform, the TAPS Electronic Spanish Platform (TAPS-ESP).

METHODS

This article describes the protocol and rationale for a study to validate the TAPS-ESP in a sample of Spanish-speaking primary care patients recruited from a network of community-based clinics in Texas (target N = 1,000). The TAPS-ESP will be validated against established substance use disorder diagnostic measures, alternative screening tools, and substance use biomarkers. The study will subsequently examine barriers and facilitators to screening with the TAPS-ESP from a provider workflow perspective using qualitative interviews with providers.

DISCUSSION

Validating a Spanish language version of the TAPS Tool could expand access to evidence-based, linguistically accurate, and culturally relevant substance use screening and brief assessment for an underserved health disparity population.

The burden of somatic diseases among people with alcohol- and drug use disorders are influenced by mental illness and low socioeconomic status. A registry-based cohort study in Norway

OBJECTIVES

Persons with alcohol use disorder (AUD) and drug use disorder (DUD) have a lower life expectancy than the general population. We examined the burden of somatic diseases among persons with AUD or DUD and investigated impact of socioeconomic status (SES) and mental health disorders on the co-occurrence of somatic diseases in these groups.

METHODS

We performed a retrospective, register-based cohort study with a 6-year follow-up of persons (aged ≥18 y) with AUD (13,478) or DUD (16,659). Cox regression analyses were used to estimate hazard ratios (HRs) of somatic diseases.

RESULTS

Patients with DUD were, on average, 10 years younger at the point of diagnosis than patients with AUD. Mental illnesses were prominent in both groups (AUD: 40.5%, and DUD: 46.9% vs 3.5% in controls). Adjusting for mental disorders, the risk of all somatic diseases among the AUD and DUD groups was reduced by 30%. Some of the elevated risk of somatic diseases among persons with AUD and DUD is explained by low SES, though less than that explained by the presence of mental disorders. The diseases with highest risk among AUD patients were metabolic disorders (16.9-fold) and hypertension (14.8-fold), and among AUD patients, viral hepatitis (23.3-fold), after adjusting for low SES and mental disorders.

CONCLUSIONS

Persons with AUD had a higher risk of most somatic diseases, while those with DUD had specific risks for infections and viral hepatitis. Mental health disorders and SES adjusted the associations regarding most somatic diseases. In general, improvement of socio-economic conditions, preferably in combination with professional support to self-manage mental health problems, will reduce the risk of somatic illness in both groups. For DUD patients, available sterile user equipment will reduce the risk of viral hepatis.

Economic analysis of out-of-pocket costs among people in opioid agonist treatment: A cross-sectional survey in three Australian jurisdictions

BACKGROUND

Out-of-pocket costs for opioid agonist treatment (OAT) constitute a barrier to treatment entry and retention.This study examines OAT clients' total out-of-pocket costs (including dispensing fees, travel costs and OAT-related appointment costs) in different treatment settings (public clinics, community pharmacies, and private clinics).

METHODS

Cross-sectional survey of 402 people with opioid drug use (OUD) in New South Wales (NSW), Victoria (VIC), Tasmania (TAS), Australia; 266 clients (66%) currently receiving methadone, buprenorphine or buprenorphine-naloxone treatment were asked about dispensing fees, travel costs and OAT-related appointment costs in the past 28 days. A two-part regression model was used to deal with non-normal distributions of costing data (right skew and excess zeros).

RESULTS

Among clients currently receiving OAT, 87% paid out-of-pocket costs. Among those who paid out-of-pocket costs (N=194), travel costs accounted for more than half of total costs (52%), followed by dispensing fees (44%). The mean monthly total out-of-pocket costs were AU$135 (SD: AU$121) for public clinics, AU$161 (SD: AU$110) to AU$214 (SD: AU$166) for community pharmacies and AU$355 (SD: AU$159) for private clinics. Compared to participants in NSW private clinics, those at public clinics paid one third the total out-of-pocket costs (coefficient = 0.33; 95%CI = 0.23-0.48) and those at NSW, TAS, VIC pharmacies paid approximately half the costs (coefficient = 0.58; 95%CI = 0.42-0.79; coefficient = 0.51; 95%CI = 0.36-0.72; coefficient = 0.47; 95%CI = 0.34-0.66, respectively). People in OAT for more than a year paid half the total out-of-pocket costs, compared with those in OAT less than a year (coefficient = 0.49, 95%CI = 0.31-0.77).

CONCLUSIONS

Participants in the current study spent one-eighth of their income on out-of-pocket costs associated with OAT representing a substantial financial burden. Total out-of-pocket costs disproportionately affects those who are newer in treatment and receiving fewer unsupervised doses. Considering and addressing total out-of-pocket costs, especially travel costs and dispensing fees, to clients is critical to prevent cost from being a barrier from receiving effective care.

Substance Use Disorders in Later Life: A Review and Synthesis of the Literature of an Emerging Public Health Concern

Substance use disorders (SUDs) among older persons are among the fastest growing health problems in the United States. The number of older persons is projected to exceed 72.1 million persons by 2030, following a trend of general population growth in the mid-1940s to 1960s. The generation, known as "baby boomers," who refashioned drug use during their 20-30s, are increasingly continuing drug habits into later life. This review aims to assess the epidemiology, impact, and treatment of geriatric SUDs. Academic databases including PubMed, PsychInfo, Ovid, and Medline, were queried up to December 2018 for terms of "geriatric," "older," "elderly," "substance abuse," "drug," "drug use," "drug abuse," "drug dependency," "illicit drugs," and "geriatric psychiatry." Articles identified included 17 government documents, 29 studies based upon government documents, 43 studies not related to US government surveys, 19 review articles, 9 commentary pieces, 4 newspaper articles, 2 textbooks, and 1 published abstract. Evaluated studies and documents together suggest that older individuals are using illicit drugs and meeting criteria for SUDs at higher rates than previous geriatric cohorts resulting in substantial negative impacts on medical and psychiatric conditions. These findings represent a novel trend since previous cohorts of older individuals were thought to rarely use illicit substances. Current treatment models are inadequate to address the new wave of older individuals with SUDs. The fields of geriatrics, addiction, and geriatric psychiatry must work together to establish comprehensive care models and treatment modalities for addressing this emerging public health concern.

The provision of preventive care for modifiable health risk behaviours by clinicians within substance use treatment settings: A systematic review

People who use substances have a high prevalence of other modifiable health risk behaviours such as tobacco smoking which contribute to an increased mortality and morbidity. Preventive care can reduce the prevalence of such behaviours and is recommended by clinical practice guidelines. This review describes the prevalence of preventive care delivery by substance use treatment healthcare providers and examines differences by treatment setting. Five databases were searched for studies published between 2005 and 2017. Eligible studies reported levels of preventive care (assessment, brief advice and/or referral/follow-up) in substance use treatment services for tobacco smoking, nutrition or physical activity. Two reviewers independently conducted article screening, data extraction and methodological quality assessment. Sixteen studies were included and all except one investigated care provision for tobacco smoking only. Four studies reported care levels as a proportion and 12 studies reported care as a score-based mean. Client-reported receipt of smoking cessation care ranged from: 79-90% for assessment; 15-79% for brief advice; 0-30% for referral/follow-up. Meta-regression analyses of 12 studies found clinician-reported preventative care for tobacco smoking was more frequently reported in studies assessing care occurring across multiple substance use treatment settings, compared to studies reporting provision in inpatient only. This review indicated that, compared to smoking cessation care, little is known about the level of preventive care for nutrition or physical activity. Overall, the delivery of smoking cessation care reported was sub-optimal. High levels of assessment relative to brief advice and low levels of referral to ongoing assistance were indicated.

Polysubstance Use Among Veterans in Intensive PTSD Programs: Association With Symptoms and Outcomes Following Treatment

Objective: A distinct group of patients has recently been described who experience polysubstance use disorder characterized by use of multiple addictive substances. This study examines baseline characteristics and longitudinal outcomes of a group of such patients in specialized intensive Veterans Health Administration posttraumatic stress disorder (PTSD) programs and followed 4 months after discharge. Methods: Patients with diagnosed PTSD or subsyndromal PTSD and who used a single substance at baseline were compared to those who used two or three and more than three different addictive substances on measures of PTSD symptom severity and functioning. Comparisons were also adjusted for differences in total days of any substance use and other potentially confounding factors. Patients were reclassified according to the number of substances used at follow-up and again compared on symptoms and functioning. Results: Bivariate analysis of baseline data (N = 8,240) showed frequent polysubstance use (n = 3,695, 44.8% of the sample) and that use of greater numbers of substances was associated with more severe PTSD symptoms as well as more total days of substance use. At follow-up after treatment, 58.2% of the original sample (n = 4,797) was assessed. Polysubstance use was less frequent (n = 756, 15.8% of the follow-up sample), but showed a similar association with more severe symptoms, although differences were attenuated after adjusting for total days of substance use. Conclusions: Polysubstance use, conceptualized within the multimorbidity perspective, is associated with increased severity of PTSD symptoms among veterans with dual diagnoses requiring complex interventions, the evaluation of which will require innovative trial designs.

Providing routine chronic disease preventive care in community substance use services: a pilot study of a multistrategic clinical practice change intervention

OBJECTIVES

To evaluate the potential effectiveness of a practice change intervention in increasing preventive care provision in community-based substance use treatment services. In addition, client and clinician acceptability of care were examined.

DESIGN

A pre-post trial conducted from May 2012 to May 2014.

SETTING

Public community-based substance use treatment services (n=15) in one health district in New South Wales (NSW), Australia.

PARTICIPANTS

Surveys were completed by 226 clients and 54 clinicians at baseline and 189 clients and 46 clinicians at follow-up.

INTERVENTIONS

A 12-month multistrategic clinician practice change intervention that aimed to increase the provision of preventive care for smoking, insufficient fruit and/or vegetable consumption and insufficient physical activity.

PRIMARY AND SECONDARY OUTCOME MEASURES

Client and clinician reported provision of assessment, brief advice and referral for three modifiable health risk behaviours: smoking, insufficient fruit and/or vegetable consumption and insufficient physical activity. Clinician-reported optimal care was defined as providing care to 80% of clients or more. Client acceptability and clinician attitudes towards preventive care were assessed at follow-up.

RESULTS

Increases in client reported care were observed for insufficient fruit and/or vegetable consumption including: assessment (24% vs 54%, p<0.001), brief advice (26% vs 46%, p<0.001), and clinicians speaking about (10% vs 31%, p<0.001) and arranging a referral (1% vs 8%, p=0.006) to telephone helplines. Clinician reported optimal care delivery increased for: assessment of insufficient fruit and/or vegetable consumption (22% vs 63%, p<0.001) and speaking about telephone helplines for each of the three health risk behaviours. Overall, clients and clinicians held favourable views regarding preventive care.

CONCLUSION

This study reported increases in preventive care for insufficient fruit and/or vegetable consumption; however, minimal increases were observed for smoking or insufficient physical activity. Further investigation of the barriers to preventive care delivery in community substance use settings is needed.

A pilot replication of QUIT, a randomized controlled trial of a brief intervention for reducing risky drug use, among Latino primary care patients

BACKGROUND

QUIT is the only primary care-based brief intervention that has previously shown efficacy for reducing risky drug use in the United States (Gelberg et al., 2015). This pilot study replicated the QUIT protocol in one of the five original QUIT clinics primarily serving Latinos.

DESIGN

Single-blind, two-arm, randomized controlled trial of patients enrolled from March-October 2013 with 3-month follow-up.

SETTING

Primary care waiting room of a federally qualified health center (FQHC) in East Los Angeles.

PARTICIPANTS

Adult patients with risky drug use (4-26 on the computerized WHO ASSIST): 65 patients (32 intervention, 33 control); 51 (78%) completed follow-up; mean age 30.8 years; 59% male; 94% Latino.

INTERVENTIONS AND MEASURES

Intervention patients received: 1) brief (typically 3-4 minutes) clinician advice to quit/reduce their risky drug use, 2) video doctor message reinforcing the clinician's advice, 3) health education booklet, and 4) up to two 20-30 minute follow-up telephone drug use reduction coaching sessions. Control patients received usual care and cancer screening information. Primary outcome was reduction in number of days of drug use in past 30days of the highest scoring drug (HSD) on the baseline ASSIST, from baseline to 3-month follow-up.

RESULTS

Controls reported unchanged HSD use between baseline and 3-month follow-up whereas Intervention patients reported reducing their use by 40% (p<0.001). In an intent-to-treat linear regression analysis, intervention patients reduced past month HSD use by 4.5 more days than controls (p<0.042, 95% CI: 0.2, 8.7). Similar significant results were found using a complete sample regression analysis: 5.2 days (p<0.03, 95% CI: 0.5, 9.9). Additionally, on logistic regression analysis of test results from 47 urine samples at follow-up, intervention patients were less likely than controls to test HSD positive (p<0.05; OR: 0.10, 95% CI: 0.01, 0.99).

CONCLUSIONS

Findings support the efficacy of the QUIT brief intervention for reducing risky drug use.

Healthcare Cost Reductions after Moving into a Wet Nursing Home Stay-A Case Series

Serious alcohol dependence is associated with high healthcare costs, especially when patients have chronic problems with alcohol, dementia and exhibit externalizing behavior. One option is to offer a wet nursing home for seriously ill patients for whom abstinence from alcohol is not a feasible option. In this case series, we present the healthcare costs 18 months before moving into a “wet nursing home”, and in the first 18 months of their stay, for three cases, one with low needs of care, one with medium needs, and one with high needs. Results: for all three patients, hospital costs were reduced by between 83.7 and 97.9% for patients with dementia, externalizing behavior, and chronic alcohol problems, a wet nursing home can produce substantial cost reductions in other parts of the healthcare sector.

Somatic health care utilization by patients treated for substance use disorders

INTRODUCTION

Patients with substance use disorder (SUD) are frequently suffering from co-occurring somatic disorders, increasing the risk of mortality. Somatic health care utilization (sHCU) often remains unknown to the physician during SUD treatment. This paper analyses sHCU and associated costs among patients in SUD treatment compared to matched, non-substance dependent controls.

METHODS

Health care utilization data on 4972 SUD patients were matched to 19,846 controls by gender, birth year and ethnic origin. Subcategories of patients were formed based on SUD and on co-morbid psychiatric disorder. Data on sHCU during the year prior to the last treatment contact (the 'index date') for both patients and their matched controls were extracted from a health insurance database.

RESULTS

Patients had a higher sHCU (with increased associated costs) than controls, especially when alcohol dependence was involved. In particular, sHCU for cardiovascular, respiratory, infectious diseases, injuries and accidents was increased among patients. However, the use of preventive medication, such as lipid-lowering drugs, is lower among SUD patients. Co-morbidity of psychiatric disorders led to further increase of sHCU, whereas patients with comorbid non-affective psychotic disorder (NAPD) showed lower sHCU and costs.

CONCLUSION

Patients with SUD overall have a high sHCU, associated with high costs. There are indications that SUD patients have less access to preventive medication. Patients with comorbid NAPD are at risk of possible underutilization of somatic health care. Furthermore, we conclude that these larger administrative databases allow for comparisons between various diagnostic categories.

Longitudinal associations between outpatient medical care use and substance use among rural stimulant users

BACKGROUND

Negative views toward substance use treatment among some rural substance users and limited treatment resources in rural areas likely affect substance use utilization. It is therefore important to determine whether accessing healthcare options other than substance use treatment, specifically outpatient medical care (OMC), is associated with reductions in substance use.

OBJECTIVES

We examined whether use of OMC was associated with reductions in substance use among rural substance users over a three-year period. We also explored whether substance user characteristics, including substance-use severity and related-problems, moderated this potential relationship.

METHODS

Data were collected from an observational study of 710 (61% male) stimulant users using respondent-driven sampling. Participants were recruited from rural counties of Arkansas, Kentucky, and Ohio.

RESULTS

We found a significant main effect of having at least one OMC visit (relative to none) on fewer days of alcohol, crack cocaine, and methamphetamine use over time. Fewer days of alcohol, crack cocaine, and methamphetamine use were reported in participants with at least one OMC visit (relative to those with none) among those reporting higher Addiction Severity Index employment and psychiatric severity scores, and low education, respectively.

CONCLUSION

Our findings extend the results from prior studies with urban substance users to show that contact with an outpatient medical care clinic is associated with reductions in substance use over time among rural substance users with especially poorer functioning. These findings highlight the potential importance of OMCs in addressing unhealthy substance use in rural communities.

Correlates of three-year outpatient medical care use among rural stimulant users

Outpatient medical care (OMC) settings are a care context in which effective management of unhealthy substance use can occur. However, no studies have documented rates of OMC use and characteristics of OMC use among rural substance users. This study sought to examine the rates and frequency of OMC use in a sample of rural drug users over a three-year period. We also explored characteristics of participants associated with use of OMCs over time. Data were collected from June 2005 to September 2007 from a natural history study of 710 stimulant users living in rural communities. Participants were adults, not in drug treatment, and reporting recent methamphetamine, crack cocaine or powder cocaine use. Between 34 and 39% of participants reported any use of an OMC over the three-year follow-up period, with a mean average number of visits ranging from one to two at each follow-up. Having medical insurance, reporting any use of substance use disorder-related care (including formal substance use treatment or mutual-help groups), and higher Addiction Severity Index (ASI) medical and psychiatric composite scores were associated with greater odds of any OMC use and higher frequency of OMC use over time. Being male and having higher ASI alcohol and drug composite scores were associated with lower odds of any OMC use and lower frequency of OMC use. Our findings support the importance of public health efforts to increase OMC use among male rural drug users and those with more severe drug and alcohol use, the important role(s) of Federally Qualified Health Centers and other OMCs in rural communities that serve those with low rates of health insurance, and the need for public health efforts to increase the use of OMCs among rural drug users not experiencing more severe medical or psychiatric health problems.

Respiratory health screening for opiate misusers in a specialist community clinic: a mixed-methods pilot study, with integrated staff and service user feedback

OBJECTIVES

Increased rates of illicit drug inhalation are thought to expose opiate misusers (OMUs) to an enhanced risk of respiratory health problems. This pilot study aimed to determine the feasibility of undertaking respiratory screening of OMUs in a community clinic.

SETTING

Single-centre UK community substance misuse clinic.

PARTICIPANTS

All clinic attendees receiving treatment for opiate misuse were eligible to participate. 36 participants (mean age=37) were recruited over a 5-week period. The sample included 26 males and 10 females.

OUTCOME MEASURES

Spirometry without bronchodilation; health related quality of life EQ-5D-3L; Asthma Control Test; Mini Asthma Quality of Life; Clinical COPD Questionnaire and the Treatment Outcome Profile were used to assess the respiratory health of participants. Findings were discussed with staff and service users in 2 patient and public involvement events and feedback was analysed thematically.

RESULTS

34 participants reported that they had smoked heroin. 8 participants diagnosed with asthma, scored under 13 on the Asthma Control Test, suggesting poorly controlled asthma. Participants (n=28), without a diagnosis of asthma completed the Lung Function Questionnaire. Of these, 79% produced scores under 18, indicating symptoms associated with the development of chronic obstructive pulmonary disease. Spirometry showed 14% of all participants had forced expiratory volume in 1 s/forced vital capacity <0.7 (without bronchodilator), indicating potential obstructive lung disease. Feedback from service users and staff suggested a willingness and capacity to deliver respiratory health screening programmes. Insight towards the difficulties service users have in accessing services and the burden of respiratory health was also provided.

CONCLUSIONS

It is feasible to undertake respiratory health screening of OMUs in a community clinic. Larger screening studies are warranted to determine the prevalence of respiratory health problems in this population. Research regarding asthma medicines adherence and access to healthcare among OMUs is also required.

The Mediating Influence of Treatment Participation Rate on Post-Treatment Employment

This study explored treatment participation rate as a mediator between individuals’ baseline alcohol use, drug use, and psychiatric issue levels and post-treatment employment status. The study sample included 106 unemployed or underemployed individuals with substance use disorders who were participants in an intensive drug abuse treatment program. Structural equation modeling was applied to examine relationships between study variables. The results showed that (a) the direct effect of individuals’ baseline alcohol use, drug use, and psychiatric issue severities reduced treatment participation rate; (b) the direct effect of treatment participation rate ameliorated post-treatment employment status; and (c) the indirect effect of individuals’ baseline alcohol use, drug use, and psychiatric issue severities on post-treatment employment status was mediated by treatment participation rate, which reduced the negative influence of baseline issue severity on employment. This significant mediating effect has both practical and theoretical importance in that it indicates the need for increased focus on treatment participation in practice and future research.

Provision of Chronic Disease Preventive Care in Community Substance Use Services: Client and Clinician Report

INTRODUCTION

People with substance use problems have a higher prevalence of modifiable health risk behaviors. Routine clinician provision of preventive care may be effective in reducing such health behaviors. This study aimed to examine clinician provision of preventive care to clients of community substance use treatment services.

METHODS

A cross-sectional survey was undertaken with 386 clients and 54 clinicians of community substance use treatment services in one health district in New South Wales, Australia. Client- and clinician-reported provision of three elements of care (assessment, brief advice and referral) for three health risk behaviors (tobacco smoking, insufficient fruit and/or vegetable consumption and insufficient physical activity) was assessed, with associations with client characteristics examined.

RESULTS

Provision was highest for tobacco smoking assessment (90% client reported, 87% clinician reported) and brief advice (79% client reported, 80% clinician reported) and lowest for fruit and vegetable consumption (assessment 23%, brief advice 25%). Few clients reported being offered a referral (<10%). Assessment of physical activity and brief advice for all behaviors was higher for clients residing in rural/remote areas.

CONCLUSION

Assessment and brief advice were provided to the majority of clients for smoking, but sub-optimally for the other behaviors. Further investigation of barriers to the provision of preventive care within substance use treatment settings is required, particularly for referral to ongoing support.

Alcohol-Related Diagnoses and All-Cause Hospitalization Among HIV-Infected and Uninfected Patients: A Longitudinal Analysis of United States Veterans from 1997 to 2011

Individuals with HIV infection are living substantially longer on antiretroviral therapy, but hospitalization rates continue to be relatively high. We do not know how overall or diagnosis-specific hospitalization rates compare between HIV-infected and uninfected individuals or what conditions may drive hospitalization trends. Hospitalization rates among United States Veterans were calculated and stratified by HIV serostatus and principal diagnosis disease category. Because alcohol-related diagnoses (ARD) appeared to have a disproportional effect, we further stratified our calculations by ARD history. A multivariable Cox proportional hazards model was fitted to assess the relative risk of hospitalization controlling for demographic and other comorbidity variables. From 1997 to 2011, 46,428 HIV-infected and 93,997 uninfected patients were followed for 1,497,536 person-years. Overall hospitalization rates decreased among HIV-infected and uninfected patients. However, cardiovascular and renal insufficiency admissions increased for all groups while gastrointestinal and liver, endocrine, neurologic, and non-AIDS cancer admissions increased among those with an alcohol-related diagnosis. After multivariable adjustment, HIV-infected individuals with an ARD had the highest risk of hospitalization (hazard ratio 3.24, 95 % CI 3.00, 3.49) compared to those free of HIV infection and without an ARD. Still, HIV alone also conferred increased risk (HR 2.08, 95 % CI 2.04, 2.13). While decreasing overall, risk of all-cause hospitalization remains higher among HIV-infected than uninfected individuals and is strongly influenced by the presence of an ARD.

Relationship Between Psychiatric Distress and Criminal History Among Intravenous Drug Abusers in Iran

BACKGROUND

Sychotropic agents (alcohol, drugs, and illicit substances) have an important effect on the occurrence or exacerbation of psychological and behavioral derangements such as criminal activity and mental abnormalities.

OBJECTIVES

The objective was to assess the relationship between psychiatric distress and criminal history among abusers of intravenous drugs, including heroin, benzodiazepine, codeine, cannabis, opium, and ecstasy.

MATERIALS AND METHODS

Criminal activity history and psychiatric distress were evaluated among intravenous drug abusers in drop-in centers (DIC) (141 subjects) and an outpatient service to delivery methadone to the addicts located in Razy Hospital (Baghdad, Iraq) (120 subjects). Logistic regression analyses using the SPSS for Windows 18.0 were used for analyzing the data.

RESULTS

About 86% of the intravenous drug abusers had psychiatric distress and 48.2% had criminal activity history. DIC addicts group had a better mental well-being compared to the other group, but criminal history rate was similar in two groups. In multiple logistic regression, addiction to heroin (odds ratio [OR] = 1.9, 95% confidence interval [CI]: 1.1 - 4.1), mental disorders (β = 0.060, P = 0.026), and low level of education was highly related with criminal activity (OR = 0.17, 95% CI: 0.03 - 0.89).

CONCLUSIONS

Higher scores in mental well-being questionnaire of DIC addicts suggest the positive effects of psychological interventions. There is a possibility of the involvement of heroin in occurrence of mental disorders and criminal activity. This finding needs further investigations by larger cohort studies.

Cocaine Abuse in Later Life: A Case Series and Review of the Literature

OBJECTIVE

To raise awareness about the growing trend of cocaine abuse in later years as an underdiagnosed, undertreated, and comorbid condition in older individuals. Three cases of cocaine use in patients over the age of 50 years in the Malcolm Randall Veterans Medical Center, Gainesville, Florida, within a 10-day span in 2013 are presented.

DATA SOURCES

PubMed was searched using combinations of keywords, including cocaine, addiction, elderly, and aging, to find articles published between 1986 and 2013.

STUDY SELECTION

In total, 37 articles were selected for inclusion on the basis of their relevance to the objective and importance to the representation of cocaine abuse, including international guidelines for addiction.

DATA EXTRACTION

Each article was reviewed for eligibility. Final decisions were made following full-text review.

RESULTS

Cocaine addiction remains a high-morbidity chronic-relapsing illness with few treatment options. A review of the literature shows that late-life cocaine use is sparsely recognized. Of particular interest are the clinical presentations in which a higher index for detection is warranted. The high rate of medical comorbidity associated with cocaine use, especially cerebrovascular deficits, presents special treatment and social challenges.

CONCLUSIONS

As the number of older individuals admitted for substance use continues to climb, clinicians must adapt to the changing demographics by increasing screening, early detection, and treatment options for older persons.

Buprenorphine maintenance treatment retention improves nationally recommended preventive primary care screenings when integrated into urban federally qualified health centers

Buprenorphine maintenance therapy (BMT) expands treatment access for opioid dependence and can be integrated into primary health-care settings. Treating opioid dependence, however, should ideally improve other aspects of overall health, including preventive services. Therefore, we examined how BMT affects preventive health-care outcomes, specifically nine nationally recommended primary care quality health-care indicators (QHIs), within federally qualified health centers (FQHCs) from an observational cohort study of 266 opioid-dependent patients initiating BMT between 07/01/07 and 11/30/08 within Connecticut's largest FQHC network. Nine nationally recommended preventive QHIs were collected longitudinally from electronic health records, including screening for chronic infections, metabolic conditions, and cancer. A composite QHI score (QHI-S), based on the percentage of eligible QHIs achieved, was categorized as QHI-S ≥80% (recommended) and ≥90% (optimal). The proportion of subjects achieving a composite QHI-S ≥80 and ≥90 % was 57.1 and 28.6%, respectively. Screening was highest for hypertension (91.0%), hepatitis C (80.1%), hepatitis B (76.3%), human immunodeficiency virus (71.4%), and hyperlipidemia (72.9%) and lower for syphilis (49.3%) and cervical (58.5%), breast (44.4%), and colorectal (48.7%) cancer. Achieving QHI-S ≥80% was positively and independently associated with ≥3-month BMT retention (adjusted odds ratio (AOR) = 2.19; 95% confidence interval (CI) = 1.18-4.04) and BMT prescription by primary care providers (PCPs) rather than addiction psychiatric specialists (AOR = 3.38; 95% CI = 1.78-6.37), and negatively with being female (AOR = 0.30; 95% CI = 0.16-0.55). Within primary health-care settings, achieving greater nationally recommended health-care screenings or QHIs was associated with being able to successfully retain patients on buprenorphine longer (3 months or more) and when buprenorphine was prescribed simultaneously by PCPs rather than psychiatric specialists. Decreased preventive screening for opioid-dependent women, however, may require gender-based strategies for achieving health-care parity. When patients can be retained, integrating BMT into urban FQHCs is associated with improved health outcomes including increased multiple preventive health-care screenings.

Somatic health of patients at an outpatient clinic for substance abuse

BACKGROUND

Previous studies have detected a considerable degree of somatic illness among substance abusers. At our outpatient clinic for substance abuse we frequently find that referral documents provide scant information on somatic illnesses, and that patients complain of poor contact with their GP. We wished to investigate these issues.

MATERIAL AND METHOD

From September 2009 to November 2012 a total of 155 of 365 patients (42%) at an outpatient clinic for substance abuse at Levanger Hospital were included in the study. Information was gathered on somatic illnesses according to ICPC using patient-reported medical history, clinical examination, laboratory tests, review of somatic hospital records and/or information from GPs. Somatic health information in referral documents, supplementary information from GPs and patient-GP relationships were examined.

RESULTS

Altogether 119 men and 36 women with an average age of 41.7 years were included. Alcohol was the preferred intoxicant for 110 patients. We found an average of 4.2 disease diagnoses and 0.8 symptom diagnoses per patient. Dental disease was present in 69 patients, hypertension in 56, allergies in 45 and morbid obesity in 37. More serious diseases such as cancer and hepatic failure were detected. ECG showed pathology in 32 of 107 patients examined. A total of 101 referrals lacked information on somatic health. Sixty doctors replied to letters containing questions regarding somatic supplementary information. A total of 92 patients reported good or acceptable contact with their GP, 19 reported poor contact and 19 declined to answer the question, while 15 patients reported no contact and 10 reported that they had just changed their GP.

INTERPRETATION

The substance abusers in this study had several somatic diagnoses, and many reported poor contact with their GPs. There are grounds for questioning whether the requirements set by the specialist health service for adequate health provisions for patients at the outpatient clinic for substance abuse are being met.

Comorbidities and race/ethnicity among adults with stimulant use disorders in residential treatment

Comorbid physical and mental health problems are associated with poorer substance abuse treatment outcomes; however, little is known about these conditions among stimulant abusers at treatment entry. This study compared racial and ethnic groups on baseline measures of drug use patterns, comorbid physical and mental health disorders, quality of life, and daily functioning among cocaine and stimulant abusing/dependent patients. Baseline data from a multi-site randomized clinical trial of vigorous exercise as a treatment strategy for a diverse population of stimulant abusers (N=290) were analyzed. Significant differences between groups were found on drug use characteristics, stimulant use disorders, and comorbid mental and physical health conditions. Findings highlight the importance of integrating health and mental health services into substance abuse treatment and could help identify potential areas for intervention to improve treatment outcomes for racial and ethnic minority groups.

Screening and brief intervention for drug use in primary care: the ASPIRE randomized clinical trial

IMPORTANCE

The United States has invested substantially in screening and brief intervention for illicit drug use and prescription drug misuse, based in part on evidence of efficacy for unhealthy alcohol use. However, it is not a recommended universal preventive service in primary care because of lack of evidence of efficacy.

OBJECTIVE

To test the efficacy of 2 brief counseling interventions for unhealthy drug use (any illicit drug use or prescription drug misuse)-a brief negotiated interview (BNI) and an adaptation of motivational interviewing (MOTIV)-compared with no brief intervention.

DESIGN, SETTING, AND PARTICIPANTS

This 3-group randomized trial took place at an urban hospital-based primary care internal medicine practice; 528 adult primary care patients with drug use (Alcohol, Smoking, and Substance Involvement Screening Test [ASSIST] substance-specific scores of ≥4) were identified by screening between June 2009 and January 2012 in Boston, Massachusetts.

INTERVENTIONS

Two interventions were tested: the BNI is a 10- to 15-minute structured interview conducted by health educators; the MOTIV is a 30- to 45-minute intervention based on motivational interviewing with a 20- to 30-minute booster conducted by master's-level counselors. All study participants received a written list of substance use disorder treatment and mutual help resources.

MAIN OUTCOMES AND MEASURES

Primary outcome was number of days of use in the past 30 days of the self-identified main drug as determined by a validated calendar method at 6 months. Secondary outcomes included other self-reported measures of drug use, drug use according to hair testing, ASSIST scores (severity), drug use consequences, unsafe sex, mutual help meeting attendance, and health care utilization.

RESULTS

At baseline, 63% of participants reported their main drug was marijuana, 19% cocaine, and 17% opioids. At 6 months, 98% completed follow-up. Mean adjusted number of days using the main drug at 6 months was 12 for no brief intervention vs 11 for the BNI group (incidence rate ratio [IRR], 0.97; 95% CI, 0.77-1.22) and 12 for the MOTIV group (IRR, 1.05; 95% CI, 0.84-1.32; P = .81 for both comparisons vs no brief intervention). There were also no significant effects of BNI or MOTIV on any other outcome or in analyses stratified by main drug or drug use severity.

CONCLUSIONS AND RELEVANCE

Brief intervention did not have efficacy for decreasing unhealthy drug use in primary care patients identified by screening. These results do not support widespread implementation of illicit drug use and prescription drug misuse screening and brief intervention.

A computational hypothesis for allostasis: delineation of substance dependence, conventional therapies, and alternative treatments

The allostatic theory of drug abuse describes the brain's reward system alterations as substance misuse progresses. Neural adaptations arising from the reward system itself and from the antireward system provide the subject with functional stability, while affecting the person's mood. We propose a computational hypothesis describing how a virtual subject's drug consumption, cognitive substrate, and mood interface with reward and antireward systems. Reward system adaptations are assumed interrelated with the ongoing neural activity defining behavior toward drug intake, including activity in the nucleus accumbens, ventral tegmental area, and prefrontal cortex (PFC). Antireward system adaptations are assumed to mutually connect with higher-order cognitive processes occurring within PFC, orbitofrontal cortex, and anterior cingulate cortex. The subject's mood estimation is a provisional function of reward components. The presented knowledge repository model incorporates pharmacokinetic, pharmacodynamic, neuropsychological, cognitive, and behavioral components. Patterns of tobacco smoking exemplify the framework's predictive properties: escalation of cigarette consumption, conventional treatments similar to nicotine patches, and alternative medical practices comparable to meditation. The primary outcomes include an estimate of the virtual subject's mood and the daily account of drug intakes. The main limitation of this study resides in the 21 time-dependent processes which partially describe the complex phenomena of drug addiction and involve a large number of parameters which may underconstrain the framework. Our model predicts that reward system adaptations account for mood stabilization, whereas antireward system adaptations delineate mood improvement and reduction in drug consumption. This investigation provides formal arguments encouraging current rehabilitation therapies to include meditation-like practices along with pharmaceutical drugs and behavioral counseling.

Physical illness in psychiatric inpatients: comparison of patients with and without substance use disorders

BACKGROUND

Physical comorbidities and substance use are commonly reported in patients with mental disorders.

AIM

To examine somatic comorbidity in patients with substance use disorders (SUD) compared to patients with mental disorders but no SUD.

METHODS

Lifetime prevalence data on mental and physical health status were collected from inpatients in 12 mental health care facilities in five different countries. Differences in somatic comorbidity were examined by means of logistic regression analysis controlling for age and gender.

RESULTS

Of 2,338 patients, 447 (19%) had a primary or secondary SUD diagnosis. In comparison to patients with other mental disorders, patients with SUD had a higher prevalence of infectious and digestive diseases but a lower prevalence of endocrine, nutritional and metabolic disorders. Patterns of physical comorbidities differed according to type of substance used (alcohol use - cardiovascular; tobacco use - respiratory, neoplasms; cannabinoid use - injuries; opioid use - infectious, digestive; benzodiazepine use - endocrine, nutritional, metabolic; stimulants - urogenital).

CONCLUSIONS

SUD are related to specific somatic health risks while some of our findings point to potentially protective effects. The widespread prescription of benzodiazepines requires research on physical health effects. Early detection of SUD and their integration into programmes targeting physical comorbidity should be a priority in organizing mental health care.

Cochrane systematic reviews in the field of addiction: past and future

BACKGROUND AND OBJECTIVE

The Cochrane Drugs and Alcohol Group aims to produce, update, and disseminate systematic reviews on the prevention, treatment, and rehabilitation of problematic drug and alcohol use. This paper describes what the Group has done since the 1990s to produce evidence to guide policy, practice, and research.

METHOD

We analyze the coverage of topics by our reviews, the body of studies they have included, and the evidence produced.

RESULTS

By July 2013, the Group had published 67 reviews, with 376 authors from 25 different countries. These reviews included 906 studies, of 3061 studies considered for inclusion. Most (90%) included studies were randomized trials. Considering the 'Implications for practice' section of each review, 41% interventions were classified as 'do it', 15% as 'do not do', and 44% as 'do only in research'. These proportions varied according to the type of substance of abuse studied. The proportion of 'do it' interventions were 46% for alcohol, 40% for opioids, 20% for psychostimulants, 40% for polydrugs, and 62% for prevention.

CONCLUSION

Cochrane Reviews produced by the Drugs and Alcohol Group provide evidence on the effectiveness of several interventions, and identify areas of uncertainty where new research is needed.

Health promotion and prevention strategies

Opiate dependency is a medical disorder that requires treatment intervention. Primary health care not only entails treatment of illness but also involves disease prevention and health promotion. Based on Pender's revised Health Promotion Model, a descriptive study comparing the health promoting behaviors/practices in abusing and recovering opiate-dependent drug users is analyzed. Using the Health Promoting Lifestyle Profile II, a comparative descriptive, exploratory, nonexperimental design study was conducted to identify key health-promoting behaviors in recovering opiate-dependent drug users. Prevention strategy recommendations are discussed, along with future research recommendations.

Accessibility versus quality of care plus retention: the formula for service delivery in Australian opioid replacement therapy?

The aim of this paper is to investigate how Australian Opioid Replacement Therapy (ORT) policy influences access to ORT treatment, including the resources required for implementation. In doing so, we also compare the accessibility of ORT treatment in Australia (AU) with ORT in the United Kingdom (UK) and United States (US). A review of government data and policy that influence service delivery was undertaken. When comparing across AU, the UK, and the US, we found several differences. To improve access to treatment in Australia more general practitioners need to provide ORT. Additionally, criteria for quality care, a centralised intake system, a national ORT treatment outcome measure, and a shift towards a recovery focus are recommended.

Ethnicity and gender comparisons of health consequences in adults with alcohol dependence

The moderating effects of ethnicity and gender on factors associated with physical health consequences in adults manifesting alcohol dependence were examined using data from the 2001-2002 US National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). Black and white respondents with a lifetime diagnosis of DSM-IV alcohol dependence were selected for the study (n = 3,852). A multiple-group structural equation model tested ethnicity, gender, and intervening variables as predictors of physical health status in alcohol-dependent men and women. Study findings offer implications for clinical practice with alcohol-dependent individuals by identifying likely target groups and problems for intervention.

Brief exposure to novel or enriched environments reduces sucrose cue-reactivity and consumption in rats after 1 or 30 days of forced abstinence from self-administration

Environmental enrichment (EE) reduces drug and sucrose cue-reactivity in rats. In a previous study we reported that 1 month of EE (large cage, toys, and social cohorts) significantly reduced sucrose cue-reactivity. In the present study, we examined whether overnight (22 h) EE would be as effective. We also examined whether social enrichment (SE), enrichment alone (SoloEE), or exposure to an alternative environment (AEnv) might account for the EE effect. Rats self-administered 10% sucrose (.2 mL/delivery) in 10 daily 2-h sessions. Sucrose delivery was accompanied by a tone+light cue. Rats were then exposed to enrichment or alternative environment conditions overnight (acute) or for 29 days (chronic). Sucrose cue-reactivity was measured after this period of forced abstinence in a session identical to training, but no sucrose was delivered with the cue. All acute conditions markedly reduced sucrose cue-reactivity after 1 day of forced abstinence compared to single-housed rats in standard vivarium housing (CON). Sucrose consumption was also significantly reduced in all groups but SoloEE in a next-day test. All acute conditions but SE significantly reduced sucrose cue-reactivity when administered just prior to Day 30 of forced abstinence; all reduced sucrose consumption in a next-day test. All chronic conditions except for SE and AEnv significantly reduced sucrose cue-reactivity on the Day 30 test and sucrose consumption in a next day test. For both acute and chronic comparisons, EE manipulations were the most effective at reducing sucrose cue-reactivity and consumption. SoloEE and EE were equally effective at reducing sucrose cue-reactivity and similarly effective at reducing sucrose consumption. This indicates that social interaction is not a necessary condition for reducing sucrose-motivated behaviors. These results may be useful in the development of anti-relapse strategies for drug and food addictions.

Effect of quality chronic disease management for alcohol and drug dependence on addiction outcomes

We examined the effect of the quality of primary care-based chronic disease management (CDM) for alcohol and/or other drug (AOD) dependence on addiction outcomes. We assessed quality using (1) a visit frequency based measure and (2) a self-reported assessment measuring alignment with the chronic care model. The visit frequency based measure had no significant association with addiction outcomes. The self-reported measure of care-when care was at a CDM clinic-was associated with lower drug addiction severity. The self-reported assessment of care from any healthcare source (CDM clinic or elsewhere) was associated with lower alcohol addiction severity and abstinence. These findings suggest that high quality CDM for AOD dependence may improve addiction outcomes. Quality measures based upon alignment with the chronic care model may better capture features of effective CDM care than a visit frequency measure.

Racial/ethnic differences in health status and morbidity among adults who use methamphetamine

Higher disease rates among ethnic-minority populations compared to Whites have been pervasive and persistent over time, and as methamphetamine (MA) use continues to penetrate ethnically diverse geographic regions across the United States, minority populations may be at increased risk for adverse MA-related health consequences, thus further contributing to poorer health among vulnerable populations. This study examines racial/ethnic differences in health status and health conditions among individuals who used MA. Data are from a natural history interview study of adult MA users (N = 512), half of whom received treatment for MA abuse, and a comparison group who had not received substance abuse treatment. Chi-square and logistic regression analyses examined differences by race/ethnicity in self-reported health status and morbidity, adjusting for age, gender, and health behaviors including MA use severity and tobacco use. Overall, back/neck injuries (27%), severe dental problems (26%), gunshot/knife injury (25%), and sexually transmitted diseases (STDs) (24%) were commonly reported. Racial/ethnic differences were observed for conditions including gunshot/knife injuries, hearing loss, and learning disabilities disproportionately affecting Latino populations, and asthma and STDs disproportionately affecting African-Americans. Results varied by whether treatment for MA abuse was received. Although poor health and morbidity were common overall, each ethnic group may be at higher risk for specific health problems. Health status and conditions in this MA-using sample are examined and discussed with reference to general population data. These findings may assist researchers and treatment providers in addressing health consequences of the increasing prevalence of MA use among minority populations. Understanding ethnic differences in health status among MA users may assist in developing interventions to target specific health care needs.

Accuracy of self-reported medical problems in patients with alcohol dependence and co-occurring schizophrenia or schizoaffective disorder

BACKGROUND

Schizophrenia and alcohol dependence (AD) are both major risk factors for a variety of medical problems, yet little is known about the medical status of patients in whom both conditions coexist.

OBJECTIVE

The objectives of this study are to assess accuracy of self-reported medical problems and to compare the accuracy reports in patients with schizophrenia or schizoaffective disorder and co-occurring AD compared to patients with AD only and to controls. Our hypothesis was that medical problems are under-reported in patients with co-occurring disorders, possibly due to the combination of alcohol use and symptoms of schizophrenia.

METHODS

Self-reported medical diagnoses were recorded and compared to medical records obtained from all area hospitals in 42 patients with schizophrenia and AD, 44 patients with schizoaffective disorder and AD, 41 patients with AD only, and 15 control subjects. Patients underwent medical history, physical examination, and review of medical records.

RESULTS

Patients with schizophrenia or schizoaffective disorder and co-occurring AD underreported their medical problems significantly more than patients with AD only and controls. Accuracy of self report was significantly lower in patients with schizophrenia-spectrum disorders plus co-occurring alcohol dependence than in AD alone or in controls. The most commonly underreported diagnoses included coronary artery disease, chronic renal failure, seizure disorder, hyperlipidemia, asthma and hypertension.

DISCUSSION

In order to detect potentially unreported medical conditions in patients with co-occurring schizophrenia/schizoaffective disorder and alcohol dependence, the use of targeted screening questionnaires is recommended in addition to physical examination and thorough review of medical records.

Chronic disease and recent addiction treatment utilization among alcohol and drug dependent adults

BACKGROUND

Chronic medical diseases require regular and longitudinal care and self-management for effective treatment. When chronic diseases include substance use disorders, care and treatment of both the medical and addiction disorders may affect access to care and the ability to focus on both conditions. The objective of this paper is to evaluate the association between the presence of chronic medical disease and recent addiction treatment utilization among adults with substance dependence.

METHODS

Cross-sectional secondary data analysis of self-reported baseline data from alcohol and/or drug-dependent adults enrolled in a randomized clinical trial of a disease management program for substance dependence in primary care. The main independent variable was chronic medical disease status, categorized using the Katz Comorbidity Score as none, single condition of lower severity, or higher severity (multiple conditions or single higher severity condition), based on comorbidity scores determined from self-report. Asthma was also examined in secondary analyses. The primary outcome was any self-reported addiction treatment utilization (excluding detoxification) in the 3 months prior to study entry, including receipt of any addiction-focused counseling or addiction medication from any healthcare provider. Logistic regression models were adjusted for sociodemographics, type of substance dependence, recruitment site, current smoking, and recent anxiety severity.

RESULTS

Of 563 subjects, 184 (33%) reported any chronic disease (20% low severity; 13% higher severity) and 111 (20%) reported asthma; 157 (28%) reported any addiction treatment utilization in the past 3 months. In multivariate regression analyses, no significant effect was detected for chronic disease on addiction treatment utilization (adjusted odds ratio [AOR] 0.88 lower severity vs. none, 95% confidence interval (CI): 0.60, 1.28; AOR 1.29 higher severity vs. none, 95% CI: 0.89, 1.88) nor for asthma.

CONCLUSIONS

In this cohort of alcohol and drug dependent persons, there was no significant effect of chronic medical disease on recent addiction treatment utilization. Chronic disease may not hinder or facilitate connection to addiction treatment.

Quality of life among treatment seeking methamphetamine-dependent individuals

As the number of men and women entering treatment for substance use disorders continues to increase across the country, it becomes vitally important to understand their quality of life (QOL) or perceived health status, in order to inform treatment efforts for improving such outcomes. To date, QOL assessments among methamphetamine (MA) dependent users are limited. This paper examines QOL health status among a sample of 838 treatment seeking MA users at admission. Using regression analysis, predictors of QOL are examined among MA users. Predictors of poor QOL among MA users at treatment admission included being female, white, high school educated or more, married, experiencing psychosocial dysfunction (lifetime trauma, suicide, social conflict), reporting a high frequency of both MA and polydrugs for 15 days or more in the past month, chronicity of MA and polydrug use, injection use, and having co-morbid medical and psychiatric impairment. Employment status was the only factor related to better health status perceptions. This study expands the scope of scholarly examination of MA-dependent users entering treatment, as there has not been a development of coherent profiles of QOL among representative samples of clinical MA-abusing populations to date.

Initiation and engagement in chronic disease management care for substance dependence

BACKGROUND

Substance dependence treatment is often episodic and not well coordinated with healthcare for common comorbidities. Chronic disease/care management (CDM), longitudinal, patient-centered care delivered by multidisciplinary health professionals, may be well suited to treat substance dependence (SD).

OBJECTIVE

To examine initiation and engagement with CDM care for SD located in a primary medical setting.

METHODS

We prospectively studied substance dependent participants enrolled in a trial of CDM addiction care. Primary study outcomes, based upon Washington Circle performance measures, were 14-day initiation of CDM care and 30-day engagement with CDM care. Factors associated with these outcomes were determined using multivariable logistic regression models. We also estimated the proportion of participants who eventually attended at least two visits and four visits by the end of the study (Kaplan-Meier method).

RESULTS

Of 282 participants, approximately half of the cohort (45%, 95% Confidence Interval [CI] 39-51%) met criteria for 14-day initiation and 23% (95% CI 18-28%) for 30-day engagement with CDM care. Most participants attended two or more (81%, 95% CI 76-85%) and four or more CDM visits (62%, 95% CI 56-68%). Major depressive episode (AOR 2.60, 95% CI 1.39, 4.87) was associated with higher odds of 14-day initiation; younger age, female sex, and higher alcohol addiction severity were associated with lower odds of 30-day engagement with CDM care.

CONCLUSION

People with SD appear to be willing to initiate and engage with CDM care in a primary medical care setting. CDM care has the potential to improve the quality of care for people with addictions.

Cochrane systematic reviews in the field of addiction: what's there and what should be

The Cochrane Drugs and Alcohol Group aims to produce, update, and disseminate systematic reviews on the prevention, treatment, and rehabilitation of problematic drug and alcohol use. The objective of the present paper was to summarize the main characteristics of the published systematic reviews in the field of drug and alcohol dependence, in terms of the topics covered, methods used to produce the reviews, and available evidence. By January 2010, the Group had published 52 reviews with 694 primary studies included out of 2059 studies considered for inclusion. Of these publications, 44% were published in 12 journals, including Drug and Alcohol Dependence (11%) with the highest number of publications, and 68% were conducted in North America. The majority of included studies (90%) were randomized controlled trials. Evaluating their methodological quality, we found that allocation concealment methods were not properly described in the majority of studies (18% adequate, 73% unclear, 9% inadequate). The percentage of interventions shown to be beneficial varied according to the substance considered: 42% for opioids, 37% for alcohol, 14% for psychostimulants, 7% for polydrugs, and 33% for prevention. Furthermore, 75% of the reviews provided specific information on further research needs. Cochrane reviews provide information on the most effective treatments, particularly in the area of opioid and alcohol dependence, and help clarify areas for further research.

Nutrition issues in the HIV-infected injection drug user: findings from the nutrition for healthy living cohort

OBJECTIVE

The purpose of this paper is to highlight disparities between injection drug users (IDUs) and those who had never been IDUs from the Nutrition for Healthy Living (NFHL) cohort. Although IDUs were enrolled in the cohort throughout its duration, few analyses have sought to highlight findings specific to them.

METHODS

NFHL, a prospective, longitudinal cohort conducted from 1995-2005, included 881 human immunodeficiency virus (HIV) -infected men and women over the age of 18. Subjects were seen every 6 months; body composition and dietary and laboratory data were collected. Individuals were classified as current IDUs, past IDUs, and never-IDUs. The classification of ever-IDU combined current and past users.

RESULTS

In NFHL, a higher proportion of ever-IDUs were women, African American, had a high school education or less, smoked, and were housing insecure and food insecure compared to never-IDUs. Ever-IDUs had lower total, soluble, and insoluble fiber and individual micronutrient intakes. A higher proportion of ever-IDUs had hepatitis C and HIV-related symptoms, used highly active antiretroviral therapy (HAART) less, and had a CD4 count <500 cells/mm3, than never-IDUs, at the study endpoint.

CONCLUSIONS

The course of HIV infection in past and current IDUs appears to be unique and requires more investigation. Physiologic and sociodemographic characteristics of IDUs contribute to poor disease management and nutritional status. Classic manifestations of HIV persist in IDUs in the HAART era.

Hepatitis C treatment eligibility and comorbid medical illness in methadone maintenance (MMT) and non-MMT patients: a case-control study

Comorbid medical illness is common in patients with chronic hepatitis C (HCV) infection and in methadone treatment (MMT) patients, yet little is known about the impact of medical illness on HCV treatment eligibility. Medical illness and HCV treatment eligibility were compared in a case-control study of 80 MMT patients entering an HCV treatment trial and 80 matched non-MMT patients entering HCV treatment in a gastroenterology clinic. 91% of MMT and 85% of non-MMT patients had chronic medical conditions. Despite similar medical severity ratings, a significantly higher proportion (77%) of non-MMT patients were eligible for HCV treatment than were MMT patients (56%) (p<.01). Specific comorbid medical and psychiatric illness led to ineligibility in only 18% of MMT and 16% of non-MMT patients. However, failure to complete the medical evaluation process was significantly (p<.001) more likely to cause ineligibility among MMT patients (19%) than non-MMT patients (0%).

Prescription use disorders in older adults

The number of older adults needing substance abuse treatment is projected to rise significantly in the next few decades. This paper will focus on the epidemic of prescription use disorders in older adults. Particular vulnerabilities of older adults to addiction will be considered. Specifically, the prevalence and patterns of use of opioids, stimulants, and benzodiazepines will be explored, including the effects of these substances on morbidity and mortality. Treatment intervention strategies will be briefly discussed, and areas for future research are suggested.
