The association between hepatitis C infection and prevalent cardiovascular disease among HIV-infected individuals.

OBJECTIVE: To examine the association between hepatitis C and prevalent cardiovascular disease (CVD) among HIV-infected individuals. DESIGN: A cross-sectional analysis of data from the HIV-Longitudinal Interrelationships of Viruses and Ethanol (HIV-LIVE) cohort, a prospective cohort of HIV-infected individuals with current or past alcohol problems. METHODS: We analysed health questionnaire and laboratory data from 395 HIV-infected individuals (50.1% co-infected with hepatitis C) using logistic regression to estimate the odds ratio (OR) for the prevalence of CVD among those co-infected with hepatitis C and HIV compared with those infected with HIV alone. RESULTS: The prevalence of CVD was higher among those co-infected with hepatitis C compared with those with HIV alone (11.1 versus 2.5%, respectively). After adjusting for age, the OR for the prevalence of CVD was significantly higher among those with hepatitis C co-infection (adjusted OR 4.65, 95% confidence interval 1.70-12.71). The relationship between hepatitis C and CVD persisted when adjusting for age and other sociodemographic characteristics, substance use, and cardiovascular risk factors in separate regression models. CONCLUSION: Co-infection with hepatitis C among a cohort of HIV-infected individuals was associated with a higher age-adjusted odds for the prevalence of CVD. These data suggest that hepatitis C infection may be associated with an increased risk of CVD among those co-infected with HIV.

Risk of mortality during four years after substance detoxification in urban adults.

The objective of this analysis was to assess the mortality rate and risk factors in adults, with substance dependence, who are not receiving primary medical care (PC). Date and cause of death were identified using the National Death Index data and death certificates for 470 adults without PC over a period of almost 4 years after detailed clinical assessment after detoxification. Factors associated with risk of mortality were determined using stepwise Cox proportional hazards models. Subjects were 76% male, 47% homeless, and 47% with chronic medical illness; 40% reported alcohol, 27% heroin, and 33% cocaine as substance of choice. Median age was 35. During a period of up to 4 years, 27 (6%) subjects died. Median age at death was 39. Causes included: poisoning by any substance (40.9% of deaths), trauma (13%), cardiovascular disease (13.6%), and exposure to cold (9.1%). The age adjusted mortality rate was 4.4 times that of the general population in the same city. Among these individuals without PC in a detoxification unit, risk factors associated with death were the following: drug of choice [heroin: hazard ratio (HR) 6.9 (95% confidence interval (CI) 1.6-31.1]; alcohol: HR 3.7 (95% CI 0.79-16.9) compared to cocaine); past suicide attempt (HR 2.1, 95% CI 0.96-4.5); persistent homelessness (HR 2.4, 95% CI 1.1-5.3); and history of any chronic medical illness (HR 2.1, 95% CI 0.93-4.7). Receipt of primary care was not significantly associated with death (HR 0.85, 95% CI 0.34-2.1). Risk of mortality is high in patients with addictions and risk factors identifiable when these patients seek help from the health care system (i.e., for detoxification) may help identify those at highest risk for whom interventions could be targeted.

Screening and brief intervention online for college students: the ihealth study.

AIMS: To test the feasibility of online alcohol screening and brief intervention (BI) by comparing (i) two approaches to inviting all students to be screened, and (ii) a minimal versus a more extensive BI. METHODS: Freshmen students at one university were randomized to receive one of two types of email invitations to an online anonymous: (i) general health assessment, or (ii) alcohol-specific assessment. All were linked to the same alcohol screening survey. Those with unhealthy alcohol use (AUDIT >or=8) were randomly assigned to minimal or more extensive online alcohol BI. RESULTS: In both invitation groups (4008 students), 55% of students completed the online screening. Overall, 37% of men and 26% of women had unhealthy alcohol use. Compared to minimal BI, more extensive BI was associated with intention to seek help among men and with a greater increase in readiness to change among women. One month after BI, 75% of students completed another assessment, 33% of women and 15% of men with unhealthy alcohol use at baseline no longer had unhealthy alcohol use. There were no significant differences on drinking measures by BI randomization group. CONCLUSIONS: Over half of an entire freshman class of college students were reached by email and completed alcohol screening and brief intervention. Even an alcohol-specific invitation did not deter students. Although brief interventions that differed had some gender specific effects on readiness to change and intention, in general, unhealthy alcohol use decreased after brief intervention. Web screening and brief intervention show promise for addressing unhealthy alcohol use by college students.

Substance abuse treatment and receipt of liver specialty care among persons coinfected with HIV/HCV who have alcohol problems.

We examined the association of substance abuse treatment with access to liver specialty care among 231 persons coinfected with HIV and hepatitis C virus (HCV) with a history of alcohol problems who were recruited and followed up in the HIV-Longitudinal Interrelationships of Viruses and Ethanol cohort study from 2001 to 2004. Variables regarding demographics, substance use, health service use, clinical variables, and substance abuse treatment were from a standardized research questionnaire administered biannually. We defined substance abuse treatment services as any of the following in the previous 6 months: 12 weeks in a halfway house or residential facility, 12 visits to a substance abuse counselor or mental health professional, day treatment for at least 30 days, or any participation in a methadone maintenance program. Liver specialty care was defined as a visit to a liver doctor, a hepatologist, or a specialist in treating hepatitis C in the past 6 months. At study entry, most of the 231 subjects (89%, n = 205) had seen a primary care physician, 50% had been exposed to substance abuse treatment, and 50 subjects (22%) had received liver specialty care. An additional 33 subjects (14%) reported receiving liver specialty care during the follow-up period. In the multivariable model, we observed a clinically important although not statistically significant association between having been in substance abuse treatment and receiving liver specialty care (adjusted odds ratio = 1.38; 95% confidence interval = 0.9-2.11). Substance abuse treatment systems should give attention to the need of patients to receive care for prevalent treatable diseases such as HIV/HCV coinfection and facilitate its medical care to improve the quality of care for individuals with substance use disorders. The data illustrate the need for clinical care models that give explicit attention to the coordination of primary health care with addiction and hepatitis C specialty care while providing ongoing support to engage and retain these patients with complex health needs.

Hepatitis C infection is associated with depressive symptoms in HIV-infected adults with alcohol problems.

OBJECTIVES: Depression is common in persons with HIV infection and with alcohol problems, and it has important prognostic implications. Neurocognitive dysfunction has been reported with chronic hepatitis C virus (HCV) infection. We hypothesized that HCV infection is associated with more depressive symptoms in HIV-infected persons with a history of alcohol problems. METHODS: We performed a cross-sectional analysis of baseline data from a prospective cohort study of 391 HIV-infected subjects with a history of alcohol problems, of whom 59% were HCV antibody (Ab) positive and 49% were HCV RNA-positive. We assessed depressive symptoms (Center for Epidemiologic Studies Depression [CES-D]) and past month alcohol consumption. In the primary analysis, we evaluated whether there were more depressive symptoms in HCV Ab-positive and RNA-positive subjects in unadjusted analyses and adjusting for alcohol consumption, gender, age, race, CD4 count, homelessness, drug dependence, and medical comorbidity. RESULTS: Mean CES-D scores were higher in subjects who were HCV Ab-positive compared with those who were HCV Ab-negative (24.3 vs 19.0; p < 0.001). In adjusted analyses, the difference in CES-D scores between HCV Ab-positive and Ab-negative subjects persisted (24.0 vs 19.0; p < 0.001). Unadjusted mean CES-D scores were also significantly higher in HCV RNA-positive subjects compared with those who were RNA-negative, and the difference remained significant (24.6 vs 19.3; p < 0.001) in adjusted analyses. CONCLUSIONS: HCV/HIV coinfected persons with a history of alcohol problems have more depressive symptoms than those without HCV, and this association is unexplained by a variety of population characteristics. These data suggest that HCV may have a direct effect on neuropsychiatric function.

Emergency department and hospital utilization among alcohol and drug-dependent detoxification patients without primary medical care.

Utilization of emergency department (ED) services and hospitalization among a cohort of substance abusers are described based on structured research interviews with 470 adults without primary care admitted to an urban residential detoxification program. Cross-sectional analysis of baseline data of subjects found nearly 19% of subjects went to an ED on 2 or more occasions in the 6 months prior to detoxification and 14% were admitted for an overnight hospitalization. Upon further analysis of past 6-month ED utilization, the following factors were independently associated with increased odds of ED use: White race; at least one month homeless in the past 5 years chronic health condition; injury in past 6 months; and subject perception that their substance abuse interfered with seeking care from a regular doctor. Subjects with cocaine as a primary problem had lower odds of ED utilization than a reference group with alcohol as a primary problem.

Need and non-need factors associated with addiction treatment utilization in a cohort of homeless and housed urban poor.

BACKGROUND: Research on addiction treatment utilization in indigent samples mainly has been retrospective, without measures of addictive consequences, social network influences, and motivation. Prospective assessment of factors influencing utilization could inform policy and clinical care. OBJECTIVE: We sought to identify factors associated with utilization of addiction treatment and mutual help groups among substance-dependent persons with high rates of homelessness. RESEARCH AND METHODS: This was a prospective cohort of patients detoxified from alcohol or drugs at baseline who were followed for 2 years in a randomized clinical trial of linkage to primary care (n = 274). Outcomes included utilization of Inpatient/Residential, Outpatient, Any Treatment, and Mutual Help Groups. Predictor variables in longitudinal regression analyses came from the literature and clinical experience, organized according to theoretical categories of Need, and non-Need (eg, Predisposing and Enabling). RESULTS: Many subjects used Inpatient/Residential (72%), Outpatient (62%), Any Treatment (88%) or Mutual Help Groups (93%) at least once. In multivariable analyses, addictive consequences (odds ratio [OR] 1.38, 95% confidence interval [CI] 1.12-1.71), motivation (OR 1.32, 95% CI 1.09-1.60), and female gender (OR 1.80, 95% CI 1.13-2.86) were associated with most treatment types (ORs are for Any Treatment). Homelessness was associated with Residential/Inpatient (for Chronically Homeless vs. Housed, OR 1.75, 95% CI 1.04-2.94). Living with one's children (OR 0.51, 95% CI 0.31-0.84) and substance-abusing social environment (OR 0.65, 95% CI 0.43-0.98) were negatively associated with Any Treatment. CONCLUSIONS: In this cohort of substance-dependent persons, addictive consequences, social network variables, and motivation were associated with treatment utilization. Non-need factors, including living with one's children and gender, also were significant.

The severity of unhealthy alcohol use in hospitalized medical patients. The spectrum is narrow.

BACKGROUND: Professional organizations recommend screening and brief intervention for unhealthy alcohol use; however, brief intervention has established efficacy only for people without alcohol dependence. Whether many medical inpatients with unhealthy alcohol use have nondependent use, and thus might benefit from brief intervention, is unknown. OBJECTIVE: To determine the prevalence and spectrum of unhealthy alcohol use in medical inpatients. DESIGN: Interviews of medical inpatients (March 2001 to June 2003). SUBJECTS: Adult medical inpatients (5,813) in an urban teaching hospital. MEASUREMENTS: Proportion drinking risky amounts in the past month (defined by national standards); proportion drinking risky amounts with a current alcohol diagnosis (determined by diagnostic interview). RESULTS: Seventeen percent (986) were drinking risky amounts; 97% exceeded per occasion limits. Most scored > or =8 on the Alcohol Use Disorders Identification Test, strongly correlating with alcohol diagnoses. Most of a subsample of subjects who drank risky amounts and received further evaluation had dependence (77%). CONCLUSIONS: Drinking risky amounts was common in medical inpatients. Most drinkers of risky amounts had dependence, not the broad spectrum of unhealthy alcohol use anticipated. Screening on a medicine service largely identifies patients with dependence--a group for whom the efficacy of brief intervention (a recommended practice) is not well established.

Impact of health literacy on depressive symptoms and mental health-related: quality of life among adults with addiction.

BACKGROUND: Health literacy has been linked to health status in a variety of chronic diseases. However, evidence for a relationship between health literacy and mental health outcomes is sparse. OBJECTIVE: We hypothesized that low literacy would be associated with higher addiction severity, higher levels of depressive symptoms, and worse mental health functioning compared with those with higher literacy in adults with alcohol and drug dependence. METHODS: The association of literacy with multiple mental health outcomes was assessed using multivariable analyses. Measurement instruments included the Rapid Estimate of Adult Literacy in Medicine (REALM), the Center for Epidemiologic Studies-Depression (CES-D) scale, the Mental Component Summary scale of the Short Form Health Survey, and the Addiction Severity Index for drug and alcohol addiction. Subjects included 380 adults recruited during detoxification treatment and followed prospectively at 6-month intervals for 2 years. Based on the REALM, subjects were classified as having either low (< or = 8th grade) or higher (> or = 9th grade) literacy levels. RESULTS: In longitudinal analyses, low literacy was associated with more depressive symptoms. The adjusted mean difference in CES-D scores between low and high literacy levels was 4 (P<.01). Literacy was not significantly associated with mental health-related quality of life or addiction severity. CONCLUSIONS: In people with alcohol and drug dependence, low literacy is associated with worse depressive symptoms. The mechanisms underlying the relationship between literacy and mental health outcomes should be explored to inform future intervention efforts.

Challenges applying alcohol brief intervention in diverse practice settings: populations, outcomes, and costs.

This article summarizes the proceedings of a symposium at the 2005 Research Society on Alcoholism, Santa Barbara, California. The purpose of the symposium was to address challenges that arise in translating evidence for efficacy of alcohol brief intervention (BI) into diverse clinical settings and populations by reviewing the literature and describing 4 research studies. Dr. Saitz reviewed the limitations in evidence for efficacy of BIs and then described results of a randomized clinical trial of brief motivational intervention for medical inpatients drinking risky amounts. Dr. Svikis presented alternative methods for identifying pregnant women in prenatal care at risk for alcohol and drug problems (including nicotine and caffeine) and BIs to reduce or eliminate use. Dr. D'Onofrio discussed results of a randomized trial of the brief negotiated interview in emergency department patients. Dr. Kraemer presented results of a decision analytic and computer-simulation model regarding the cost-effectiveness of alcohol screening and intervention in primary care settings. Finally, Dr. Perl discussed the salient issues and suggested future directions for work in the area of alcohol BI.

Barriers to treatment of hepatitis C in HIV/HCV-coinfected adults with alcohol problems.

BACKGROUND: Alcohol use and human immune deficiency virus (HIV) infection are both associated with accelerated progression of hepatitis C virus (HCV) disease and reduced response rates to interferon therapy. In this study, we assessed the prevalence of barriers to interferon treatment in a population of HIV/HCV-coinfected patients with current or past alcohol problems and the extent to which they received treatment to address the barriers. METHODS: This is a cross-sectional, descriptive analysis of baseline data from a prospective study assessing the impact of HCV and alcohol use on HIV disease progression. Using consensus guidelines, subjects were categorized as having absolute, relative, or no contraindications to interferon therapy for HCV. Absolute contraindications to treatment included heavy alcohol use, decompensated liver disease, CD4 cell count <100 cells/microL, recent needle sharing, and suicidal ideation. Relative contraindications included moderate alcohol use, recent injection drug use, depressive symptoms, and CD4 cell count from 100 to 199 cells/microL. RESULTS: Of 401 HIV-infected subjects, 200 were HCV RNA-positive. Fifty-three percent had an absolute contraindication to interferon therapy, 35% a relative but no absolute contraindication, and only 12% had no contraindication. Of those with an absolute contraindication, 61% reported heavy drinking and the majority (88%) had multiple contraindications. These contraindications were present despite the fact that over 50% were in receipt of substance abuse and mental health treatment. CONCLUSIONS: Continued alcohol and drug use as well as depressive symptoms are the major barriers to interferon therapy in HCV/HIV-coinfected subjects and these barriers persist despite high treatment rates for these problems. Therefore, more intensive treatments of alcohol, drug, and mental health issues are needed to improve HCV treatment eligibility in HCV/HIV-coinfected persons.

Teaching internal medicine resident physicians about Alcoholics Anonymous: a pilot study of an educational intervention.

Greater physician confidence in treating alcoholism is associated with a higher frequency of referring alcoholic patients for treatment, but many physicians have limited experience with Alcoholics Anonymous. We implemented a brief, didactic and experiential educational intervention about AA and evaluated its effect on knowledge and attitudes, using a before-after repeated measures study design. Thirty-six first-year internal medicine resident physicians received an educational intervention, which consisted of a 45-minute lecture about AA, a visit to an AA meeting, and a 30-minute debriefing session the next day. Residents' knowledge and attitudes were assessed by a brief written anonymous survey before and after the educational intervention. Residents reported increases in self-perceived knowledge about AA and had more favorable attitudes towards AA after the intervention. Our pilot study shows that a brief, didactic and experiential course can improve physician knowledge and attitudes about AA, and holds promise for improving physician interface with this commonly used intervention.

The use of the mini-mental state examination in recruitment for substance abuse research studies.

BACKGROUND: Substance abuse is associated with cognitive impairment. Participation in clinical addiction research can be cognitively demanding. Screening tools can identify cognitively impaired subjects. We examined the use of the mini-mental state examination (MMSE) as an entry criterion in three randomized controlled substance abuse clinical trials. METHODS: In each of the three studies, we calculated the proportion of subjects excluded due to MMSE scores (<21) suggestive of cognitive impairment. We estimated the potential impact on enrollment based on the number of excluded subjects. Separately, for two of the studies, we assessed the impact of cognitive function on participation in follow-up using multivariable logistic regression. RESULTS: Of all persons screened for enrollment, 1.6% (171/10,791) were ineligible based solely on a MMSE score of <21. We estimate that 119 of these 171 ineligible persons would have consented and enrolled. These 119 persons would have represented 9.3% of all enrolled subjects across these studies. For subjects in a study in an inpatient detoxification unit, a higher MMSE score was associated with higher odds (adjusted odds ratio 1.15, 95% CI 1.03-1.30) of completing at least one follow-up assessment. A similar impact on subject follow-up was not observed in a study of medical inpatients with unhealthy alcohol use (adjusted odds ratio 1.01, 95% CI 0.86-1.20). CONCLUSION: Screening for cognitive impairment using the MMSE excludes a small, but substantial, number of persons from addiction research studies. Cognitive ability, as captured by the MMSE may impact follow-up. These data support cognitive screening of substance abuse research subjects.

Relationship of depressive symptoms and mental health functioning to repeat detoxification.

To better understand residential detoxification use, we assessed the roles of depressive symptoms (DS) and mental health functioning (MHF) on repeat detoxification. A prospective cohort of residential detoxification patients (N=400) without primary medical care was followed over 2 years at 6-month intervals. Subsequent detoxification admissions were examined using a statewide administrative database and DS (Center for Epidemiologic Studies Depression Scale) and MHF (SF-36 mental component summary subscale) measurements at follow-up. Incidence rate ratios of return to detoxification were estimated using multivariable longitudinal Poisson regression. In separate analyses, greater DS and worse MHF predicted higher detoxification use rates. Clinically significant worsening (10 points) of DS and MHF on objective scales predicted a 20% increased rate of detoxification readmission. Male sex, heroin as a problem substance, and race/ethnicity each predicted detoxification use. These data suggest that identifying individuals with DS or worse MHF after detoxification may provide opportunities for clinical intervention to reduce recurrent residential detoxification.

Health utility ratings for a spectrum of alcohol-related health states.

BACKGROUND: Preference-based utility ratings for health conditions are important components of cost-utility analyses and population burden of disease estimates. However, utility ratings for alcohol problems have not been determined. OBJECTIVES: The objectives of this study were to directly measure utility ratings for a spectrum of alcohol-related health states and to compare different methods of utility measurement. DESIGN, SETTING, AND SUBJECTS: The authors conducted a cross-sectional interview of 200 adults from a clinic and community sample. METHODS: Subjects completed computerized visual analog scale (VAS), time tradeoff (TTO), and standard gamble (SG) utility measurement exercises for their current health, a blindness scenario, and for 6 alcohol-related health state scenarios presented in random order. The main outcome measures were the utility ratings, scaled from 0 to 1, and anchored by death (0) and perfect health (1). RESULTS: The 200 subjects were middle-aged (mean, 41 +/- 14 years), 61% women, and racially diverse (48% black, 43% white). Utility ratings decreased as the severity of the alcohol-related health state increased, but differed significantly among the VAS, TTO, and SG methods within each health state. Adjusted mean (95% confidence interval) utility ratings for alcohol dependence (VAS, 0.38 [0.34-0.41]; TTO, 0.54 [0.48-0.60]; SG, 0.68 [0.63-0.73]) and alcohol abuse (VAS, 0.53 [0.49-0.56]; TTO, 0.71 [0.65-77]; SG, 0.76 [0.71-0.81]) were significantly lower than utility ratings for nondrinking, moderate drinking, at-risk drinking, current health, and blindness. CONCLUSIONS: Utility ratings for alcohol-related health states decrease as the severity of alcohol use increases. The low utility ratings for alcohol abuse and alcohol dependence are similar to those reported for other severe chronic medical conditions.

Homeless chronicity and health-related quality of life trajectories among adults with addictions.

BACKGROUND: New federal initiatives target funds toward chronically homeless as distinct from other homeless persons. Few data exist, however, to substantiate the implications of chronic homelessness for major health outcomes. OBJECTIVES: Using data from a 2-year cohort of addicted persons, we tested whether changes in mental and physical health-related quality of life (HRQOL) differed according to homeless chronicity. METHODS: Using self-reported homelessness, we classified subjects as chronically homeless (CH; n = 60), transitionally homeless (TRANS; n = 108), or as housed comparison subjects (HSD; n = 106). The Short Form-36 Health Survey, administered at baseline and 2 follow-ups over a period of 2 years, provided a Mental Component Summary (MCS) and a Physical Component Summary (PCS) for HRQOL. Mixed model linear regression was used to test the association between housing status, MCS, and PCS. Additional models assessed whether medical, psychiatric, addiction, and social support measures could account for HRQOL differences. RESULTS: All subjects had low MCS scores at study entry (mean, 31.2; SD, 12.6). However, there was a significant housing status-by-time interaction (P = 0.01). At final follow-up, CH and TRANS subjects had lower adjusted MCS scores than HSD subjects (33.4, 38.8, and 43.7 for the 3 groups, respectively; all P < or = 0.01). By contrast, housing status and PCS were not significantly associated (P = 0.19). Medical, psychiatric, addiction, and social support variables had significant associations with MCS, and their inclusion in the regression reduced the apparent effect of housing status on MCS. CONCLUSIONS: Chronic homelessness was associated with especially poor mental but not physical HRQOL over time. These findings reinforce a new typology of homelessness.

Primary medical care and reductions in addiction severity: a prospective cohort study.

AIMS: To assess whether receipt of primary medical care can lead to improved outcomes for adults with addictions. DESIGN: We studied a prospective cohort of adults enrolled in a randomized trial to improve linkage with primary medical care. METHODS: Subjects at a residential detoxification unit with alcohol, heroin or cocaine as a substance of choice, and no primary medical care were enrolled. Receipt of primary medical care was assessed over 2 years. Outcomes included (1) alcohol severity, (2) drug severity and (3) any substance use. FINDINGS: For the 391 subjects, receipt of primary care (> or = 2 visits) was associated with a lower odds of drug use or alcohol intoxication (adjusted odds ratio (AOR) 0.45, 95% confidence interval (CI) 0.29-0.69, 2 d.f. chi(2)P = 0.002). For 248 subjects with alcohol as a substance of choice, alcohol severity was lower in those who received primary care [predicted mean Addiction Severity Index (ASI) alcohol scores for those reporting > or = 2, 1 and 0 visits, respectively, 0.30, 0.26 and 0.34, P = 0.04]. For 300 subjects with heroin or cocaine as a substance of choice, drug severity was lower in those who received primary care (predicted mean ASI drug scores for those reporting > or = 2, 1 and 0 visits, respectively, 0.13, 0.15 and 0.16, P = 0.01). CONCLUSIONS: Receipt of primary medical care is associated with improved addiction severity. These results support efforts to link patients with addictions to primary medical care services.
