The excess medical cost and health problems of family members of persons diagnosed with alcohol or drug problems.

BACKGROUND: Having a family member with substance use problems affects family functioning, which may lead to increased medical problems and increased health care utilization and costs in the other family members. AIM: We sought to estimate the excess medical costs and prevalence of diagnosed health conditions of family members of persons with an alcohol or drug diagnosis (AOD) compared with the family members of similar persons without an AOD. METHODS: Using a large health plan's administrative databases, we identified persons who received an AOD between 2001 and 2004 and a similar group of persons with no AOD during that time. Using a hierarchical linear mixed model, we compared the cost and utilization of the family members of the AOD and non-AOD patients in the 2 years prior to the AOD patient's first AOD. Using logistic regression, we determined whether the family members of patients with AODs were more likely than comparison family members to be diagnosed with medical conditions. RESULTS: Family members of patients with AODs had greater health care costs than comparison family members in the second year before the index date (490 dollars) and in the year before the index date (433 dollars). This was the case for both adult and child family members. They also were more likely to be diagnosed with many medical conditions, especially substance abuse and depression. CONCLUSIONS: Family members of patients with AODs have greater health care costs and are more likely to be diagnosed with a number of medical conditions than family members of similar persons without an AOD.

Nonmedical use of prescription drugs among a longitudinal sample of dependent and problem drinkers.

BACKGROUND: Increasing trends in the nonmedical use of prescription drugs (NMPD) have been documented, yet little is known about the demographic, severity, and social network influences related to NMPD among treated and untreated problem and dependent drinkers. METHODS: To determine NMPD over four post-baseline interviews, the current study uses a 7-year longitudinal sample of 1598 dependent and problem drinkers, many also using illegal drugs, who were identified through a probability survey in the general population and consecutive intakes in public and private chemical dependency treatment programs in a California county. A panel model incorporating variables from the four post-baseline interviews was used, with baseline variables added for control. RESULTS: The use of illegal drugs (OR=2.18, CI 1.28-3.70), including marijuana (OR=2.66, CI 1.74-4.08), and the nonmedical use of prescription drugs prior to the baseline interview (OR=2.53, CI 1.48-4.33) were related to NMPD over the study period. Larger heavy alcohol and drug using social networks were also related to NMPD (OR=1.03, CI 1.01-1.05). CONCLUSIONS: When examining a sample of dependent and problem drinkers, many of the results obtained were similar to results in the literature predicting drug, and even alcohol, use more generally. In this sample, illegal drug use, and marijuana use were important predictors of NMPD. Thus, the nonmedical use of prescription drugs may not be the first problem noticed by health and psychiatric providers.

Adolescents entering chemical dependency treatment in private managed care: ethnic differences in treatment initiation and retention.

PURPOSE: There has been little research on adolescents of different ethnicities in chemical dependency (CD) treatment, despite a focus on ethnic disparities in health care in recent years. In particular, little is known about ethnic differences in utilization of adolescent CD services. METHODS: We examined treatment initiation and treatment retention in a sample of African American, Native American, Latino, Asian American, and Caucasian adolescents entering CD treatment in a private, managed care health plan (n = 419). Our conceptual framework included ethnicity as the main factor as well as measures of external pressure and internal motivation/readiness for treatment, family environment, psychiatric co-morbidities, and severity of alcohol and drug problems. Logistic and Poisson regression were used to examine differences. RESULTS: The study found ethnic differences in treatment initiation and treatment retention. Native American adolescents had lower odds of returning after intake to initiate treatment compared with Caucasians (odds ratio [OR] .35, p = .009), and African American youth spent less time in treatment than Caucasians (RR: .49, p < .001). CONCLUSIONS: Study findings indicate differences in treatment initiation for Native Americans and in treatment retention for African Americans. Intake and orientation sessions offer an opportunity to intervene with Native American youth. Given their high psychiatric co-morbidity, they may also benefit from the availability of psychiatric services. Even after adjusting for severity, we found shorter treatment retention for African American adolescents and suggest that organizational factors, such as cultural competency, may play an important role.

Adolescents with co-occurring substance use and mental conditions in a private managed care health plan: prevalence, patient characteristics, and treatment initiation and engagement.

This study examined the prevalence, patient characteristics, and treatment initiation and engagement of adolescents with co-occurring substance use (SU) and serious mental health (MH) diagnoses in a private, managed care health plan. We identified 2,005 adolescents aged 12-17, who received both SU and MH diagnoses within a 1-year window between 1/1/2000 and 12/31/2002; 57% were girls. Gender variations were found in diagnoses received and point of identification. Being dually diagnosed in specialty departments (rather than Primary Care and Emergency) and receiving both diagnoses within a shorter time period were associated with treatment initiation and engagement.

Health care services use by adolescents with intakes into an outpatient alcohol and drug treatment program.

We examined utilization and cost in the 1 year pre- and post-intake among a sample of adolescents (N=419) entering chemical dependency (CD) treatment. Multivariate analyses showed that these youth used significantly more medical services than a demographically matched sample of members without substance use (SU) problems. Their utilization and costs were higher than matched members, and they did not show the same reductions in post-treatment costs that adults do. This is of concern since it would appear that the medical and mental health problems of adolescents entering CD treatment may be so severe that there are no short-term reductions in post-treatment cost, including ER and hospitalizations.

Chemical dependency patients with cooccurring psychiatric diagnoses: service patterns and 1-year outcomes.

BACKGROUND: Improving services and treatment outcomes for individuals with cooccurring alcohol and drug use disorders and psychiatric conditions has been a critical challenge to clinicians and policy makers. This study examined 1-year outcomes for individuals entering chemical dependency (CD) treatment with and without cooccurring psychiatric diagnoses targeted by California parity legislation. Among those with cooccurring conditions (i.e., dual-diagnosis patients), we examined a model including individual characteristics, treatment services, and extratreatment characteristics to understand CD outcome predictors in this population. We hypothesized that longer CD treatment duration and receiving psychiatric services would predict higher abstinence levels. In particular,patterns of psychiatric services (amount of services, receiving a critical dose, or receiving services concurrently with CD treatment) were assessed in relation to outcome. METHODS: We examined abstinence rates 1 year after intake for 747 adults with and without cooccurring conditions. Among dual-diagnosis patients, logistic regression was used to examine predictors of abstinence. RESULTS: At baseline, dual-diagnosis patients (N=104) had higher levels of medical, family, and employment problems than others. They had similar CD retention and received more psychiatric services during the year after intake and had comparable CD outcomes at 1 year. Length of stay in CD treatment, hours of psychiatric services, number of months with concurrent CD and psychiatric services, and number of 12-step meetings attended were independent predictors of abstinence for dual diagnosis patients. CONCLUSIONS: Chemical dependency outcomes in patients with cooccurring psychiatric conditions were positively associated with the number and patterning of services. Receiving psychiatric services concurrently with CD treatment may be beneficial for dual-diagnosis patients. Future studies should examine how best to integrate services to optimize treatment outcomes.

Course of recovery from alcoholism.

This article represents the proceedings of a symposium at the 2005 Research Society on Alcoholism meeting in Santa Barbara, California, organized and chaired by Kamilla L. Venner. This symposium integrated current empirical research on the course of recovery from alcoholism from multiple perspectives, an aim that is consistent with NIAAA's new focus on the process of recovery. The presentations and presenters were as follows: (1) The Role of Community Services and Informal Support on 7-Year Drinking Outcomes in Treated and Untreated Drinkers, by Helen Matzger; (2) The Sequence of Recovery Events in a Native American Sample, by Kamilla L. Venner; (3) Transformational Change in Recovery, by Alyssa A. Forcehimes; (4) Social Settings and Substance Use: Contextual Factors in Recovery, by Rudolf H. Moos; and (5) A Broader View of Change in Drinking Behavior, by discussant Mark L. Willenbring. A theme connecting the presentations was that treatment is but one discrete aspect to recovery and that sustained recovery is often influenced by an individual interaction with others within a social context. Collectively, presentations underscored the need to think more broadly about factors contributing to the remission of alcohol dependence.

Addiction treatment history, medical services utilization, and cost: a longitudinal analysis of problem drinkers.

Few studies have examined the long-term patterns of health services utilization and cost for alcohol use disorders. This paper used data from baseline, 3-year, and 5-year follow-up interviews to compare utilization and cost of medical care services for problem drinkers who received chemical dependence treatment and those who did not. The analysis examined overnight hospital stays, emergency room visits, and medical office visits. The unadjusted analysis indicates that in the year immediately preceding each follow-up period, a significantly higher percentage of the chemical dependency treatment group stayed overnight at a hospital or used ER services. In terms of medical office visits, a significantly lower percentage of the treatment sample had office visits at the 5-year follow-up, but otherwise no significant differences existed. Most of the significant differences between the two groups vanished when we controlled for covariates. Researchers, policy makers, and clinicians could benefit from such information to develop alternative delivery models, formulate research initiatives, and determine areas for potential intervention and improvement.

Translating research findings into practice: example of treatment services for adolescents in managed care.

An important question in the alcoholism treatment field is how research findings can be translated into real-world clinical practice. Researchers have developed a new research-practice integration (RPI) model that can both drive the formulation of studies and new research questions and promote improvements in treatment quality. The hallmark of this model is a collaborative relationship between the key stakeholders in both alcohol and other drug (AOD) treatment and research, including health plan administrators and clinicians, treatment program administrators, psychiatry and primary care departments, patients and their families, purchasers, and researchers. The issue of technology transfer is especially relevant in the realm of adolescent AOD treatment. The implementation and feasibility of the RPI model are illustrated by a case study of a managed health care plan's treatment services for adolescents with AOD dependence. In this setting, key research findings are being used to shape the plan's adolescent health services.

Adolescents in private chemical dependency programs: who are most at risk for HIV?

Consecutive intakes (N = 419) between ages 13 and 18 years to chemical dependency (CD) programs in a large private health plan were interviewed. The prevalence of six HIV risk behaviors was measured and categorized into zero, one, and multiple risk groups. The relationships between both demographic characteristics and substance use with HIV risk behaviors were examined. Approximately half the sample reported at least one risk behavior, with 17% reporting multiple risk behaviors. Those most likely to report multiple risk behaviors were heavy drinking boys, as well as girls who reported using narcotic analgesics. Implications of these findings for pediatricians and CD clinicians are discussed.

Chemical dependency and psychiatric services for adolescents in private managed care: implications for outcomes.

BACKGROUND: Many adolescents with alcohol and drug problems have mental health comorbidities. The literature suggests that patients entering chemical dependency (CD) treatment with co-occurring problems have less successful outcomes, including treatment dropout and relapse. We examined the impact of psychiatric services on treatment initiation, retention, and alcohol and drug abstinence outcomes for adolescents in CD treatment. METHODS: Participants were 419 adolescents aged 12-18 years who were seeking treatment at four CD programs of a nonprofit, managed care, group model health system and a parent or guardian for each adolescent. We surveyed participants at intake and 6 months and examined clinical and administrative data on diagnoses and CD and psychiatric utilization. Six-month response rates were 91% for adolescents and 93% for parents. RESULTS: Fifty-five percent of the patients with treatment intakes had at least one psychiatric diagnosis in addition to a substance use disorder. Compared with matched controls, patients with CD intakes had higher rates of depression, anxiety, eating disorders, attention deficit hyperactivity disorder, conduct disorder, and conduct disorder including oppositional defiant disorder. Thirty-one percent of the full sample had psychiatric visits in the 6 months after intake; among those with a psychiatric diagnosis, 54% had a psychiatric visit. Girls and those with higher Youth Self-Report internalizing scores were more likely to have a psychiatric visit (OR = 2.27, p < 0.001 and OR = 1.05, p < 0.0001, respectively). Adolescents receiving psychiatric services were more likely to be abstinent from both alcohol and drugs than those not receiving these services (OR = 1.57, 95% CI = 0.98-2.5) and more likely to be alcohol abstinent (OR = 1.68, 95% CI = 1.00-2.85). Those adolescents at colocated clinics had higher odds of abstinence from both alcohol and drugs (OR = 1.57, 95% CI = 1.03-2.39) and drugs (OR = 1.84, 95% CI = 1.87-2.85) and of returning after intake to initiate CD treatment (OR = 2.28, 95% CI = 1.44-3.61, p < 0.001) than others. CONCLUSIONS: Our results demonstrate the need for psychiatric treatment of adolescents in CD treatment and highlight the importance of their receiving such services.

Hazardous drinkers and drug users in HMO primary care: prevalence, medical conditions, and costs.

BACKGROUND: There exists substantial evidence that individuals with alcohol and drug disorders have heightened comorbidities and health care costs. However, little is known about the larger population of "hazardous" drinkers (those whose consumption increases their "risk of physical and psychological harm") and drug users. METHODS: A sample of 1,419 patients from HMO primary care clinics was screened for hazardous drinking and drug use. Health plan databases were used to examine medical conditions and health care costs of hazardous drinkers and drug users in the year prior to screening, in comparison to 13,347 patients from the same clinics, excluding those screened. RESULTS: We found a prevalence of 7.5% for hazardous drinking and 3.2% for drug use in primary care (10% had at least one of the two problems). Hazardous drinkers and drug users had heightened prevalences for eight medical conditions, including costly conditions such as injury and hypertension, and psychiatric conditions. Medical costs for the year examined were not higher, except for those who also had psychiatric conditions. CONCLUSIONS: The prevalence of hazardous drinking and drug use was similar to hypertension and diabetes. Hazardous drinkers and drug users' heightened medical conditions, especially those related to alcohol and drug abuse, indicate that screening and brief intervention at this lower threshold of hazardous drinking and drug use will detect individuals with health risks sooner. Optimal treatment and prevention of some medical disorders may require identification and intervention of underlying hazardous alcohol or drug use.

Alcoholics anonymous careers: patterns of AA involvement five years after treatment entry.

BACKGROUND: Most formal treatment programs recommend Alcoholics Anonymous (AA) attendance during treatment and as a form of aftercare, but we know very little about treatment seekers' patterns of AA involvement over time and how these relate to abstinence. METHOD: This paper applies latent class growth curve modeling to longitudinal data from 349 dependent drinkers recruited when they were entering treatment and were re-interviewed at one or more follow-up interviews one, three and five years later, and who reported having attended AA at least once. RESULTS: Four classes of AA "careers" of meeting attendance emerged: The low AA group mainly just attended AA during the 12 months following treatment entry. The medium and high AA groups were characterized by stable attendance at the second and third follow-ups-at about 60 meetings a year for the medium group and over 200 meetings per year for the high group, followed by slight increases for the medium group and slight decreases for the high group by year five. The declining AA group doubled its meeting attendance postbaseline, to almost 200 meetings during the year following treatment entry, but by year five they were only attending about six meetings on average. Decreases in AA meetings did not necessarily signal disengagement from AA; at the five-year follow-up, a third of the low AA group and over half of the declining AA group said they felt like a member of AA. Activities other than meeting attendance, such as having a sponsor, otherwise paralleled the meeting careers, but social networks were similar by year five. Rates of abstinence by year five (for the past 30 days) were 43% for the low AA group, 73% for the medium group, 79% for the high group and 61% for the declining group. Rates of dependence symptoms and social consequences of drinking did not differ between the groups at year five. CONCLUSIONS: The prototypical AA careers derived empirically are consistent with anecdotal data about AA meetings: some never connect; some connect but briefly; and others maintain stable (and sometimes quite high) rates of AA attendance. However, contrary to AA lore, many who connect only for a while do well afterwards.

Reasons for drinking less and their relationship to sustained remission from problem drinking.

AIMS: To compare representative general population and treated samples on their reasons for drinking less and whether particular reasons were related to sustained remission from problem drinking for either group. PARTICIPANTS AND DESIGN: A total of 659 problem drinking adults in a Northern California county identified through a probability survey in the general population (n = 239) and a survey of consecutive admissions to public and private alcohol and drug programs (n = 420), who reported drinking less at the one-year follow-up and provided reasons for reducing their drinking, were assessed 1-, 3-, and 5-years post-baseline regarding their problem drinking status. MEASUREMENTS: Logistic regression models were used to predict sustained remission from problem drinking. RESULTS: While the treated sample endorsed a majority of reasons in significantly higher proportions than the general population sample, the same three reasons were significant for both groups in predicting sustained remission from problem drinking: hitting rock bottom, experiencing a traumatic event and undergoing a spiritual awakening. Interventions by medical personnel and family members were either non-significant predictors or significantly negatively related to sustained improvement for both general population and treated problem drinkers. CONCLUSIONS: General population and treatment samples have similar reasons for cutting down as they relate to sustained remission from problem drinking.

Dependent and problem drinking over 5 years: a latent class growth analysis.

Understanding the long-term course of problematic drinking is a fundamental concern for health services research in the alcohol field. The stability of, or change in, the course of drinking--especially heavy drinking--has both theoretical and applied relevance to alcohol research. We explore the application of latent class growth modeling to 5 years of survey data collected from dependent and problem drinkers--some not in treatment at baseline--in an attempt to uncover prototypical longitudinal drinking patterns. Results indicated that five profiles of drinkers can be used to represent their longitudinal course of alcohol consumption: early quitters (N = 88), light/non-drinkers (N = 76), gradual improvers (N = 129), moderate drinkers (N = 229), and heavy drinkers (N = 572). Significant baseline factors included ASI drug severity, dependence symptoms, and marital status. Attendance at AA meetings, the size of one's heavy drinking and drug using social network, past treatment, receiving suggestions about one's drinking, and contacts with the medical system were significant influences. The size of heavy drinking and drug using social networks was noticeably larger for the heavy drinkers. Findings also support the usefulness of a semi-parametric latent group-based approach as a tool for analyzing alcohol-related behaviors.

Adolescents with substance diagnoses in an HMO: factors associated with medical provider referrals to substance abuse and mental health treatment.

This study examines the factors related to referrals of adolescents with substance use disorders to substance abuse or mental health treatment by their medical providers. Administrative and chart review data from the membership of a large private health maintenance organization (HMO) were collected from a probability sample of 400 adolescents, ages 13-18, who were diagnosed with a substance use disorder in 1999. Logistic regression analyses examined referral to substance abuse treatment and referral to mental health treatment in the aggregate and stratified by gender. Documented use of both alcohol and another illicit drug, and legal problems increased likelihood of referral to substance abuse and mental health treatment, whereas diagnoses of alcohol and marijuana use disorders decreased likelihood of referral to substance abuse treatment. Mental health diagnoses played a limited role in both types of referrals, although specific psychosocial problems were associated with increased likelihood of referrals. Treatment history and location of first mention of problem were significant predictors of referral. There were no gender differences in referral rates to either substance abuse or mental health treatment; however predictors of referral differed by gender. These findings extend our knowledge about factors that influence clinicians' treatment referrals of adolescents with substance abuse diagnoses and have implications for influencing clinician referral behavior within health plans.
