Substance use, dependence, and service utilization among the US uninsured nonelderly population

OBJECTIVES: We examined the prevalence and correlates of substance use, dependence, and service utilization among uninsured persons aged 12 to 64 years. METHODS: We drew study data from the 1998 National Household Survey on Drug Abuse. RESULTS: An estimated 80% of uninsured nonelderly persons reported being uninsured for more than 6 months in the prior year. Only 9% of these uninsured persons who were dependent on alcohol or drugs had received any substance abuse service in the past year. Non-Hispanic Whites were an estimated 3 times more likely than Blacks to receive substance abuse services. CONCLUSIONS: Compared with the privately insured, uninsured persons had increased odds of having alcohol/drug dependence and appeared to face substantial barriers to health services for substance use problems.     

Use of drugs among persons admitted to a country jail.

Examinations of 427 prisoners at the time of the admission to a large urban county jail showed that more than a quarter were, or had been, users of potentially addictive drugs. Except for their drug problems, the drug users did not present any more of different health problems than the nonusers. The treatment for drug abuse recommended by the examining physicians was, for the most part, not available in the facility. Evidence of continued drug use in the jail by less than 10 per cent of the prisoners was obtained at 4-week and 8-week followup examinations. Detection of drug use by means of questionnaires and urine testing was shown to be feasible among persons admitted to such a jail.     

Characteristics of older adults referred to a psychiatric emergency outreach service

Although older adults typically underutilize mental health services, problems associated with dementing illnesses, chronic medical illnesses, affective disorders, social isolation, and multiple medication use, among other phenomena, have increased referrals of the elderly to psychiatric emergency services. The present study reviewed characteristics of elderly adults referred to a psychiatric emergency outreach/screening service. Of all individuals for whom a referral was made, 24% were aged 60 or older. Among those older adults referred, 63% were seen by screening service personnel; 37% did not meet screening criteria or voluntarily sought mental health services. Diagnoses of individuals evaluated included dementia (27%), affective disorders (27%), schizophrenia (16%), psychosis (12%), alcohol abuse (7), and diagnosis deferred (11%). Findings highlight the limited options available for mental health care of the aged.     

Mental health and social characteristics of the homeless: a survey of mission users.

Selected mental health and social characteristics of 51 homeless persons drawn as a probability sample from missions are compared to those of 1,338 men aged 18-64 years living in households from the NIMH Epidemiologic Catchment Area survey conducted in Eastern Baltimore. Differences between the two groups were small with respect to age, race, education, and military service but the differences in mental health status, utilization patterns, and social dysfunction were large. About one-third of the homeless scored high on the General Health Questionnaire which measures distress. A similar proportion had a current psychiatric disorder as ascertained by the Diagnostic Interview Schedule (DIS), with the homeless exhibiting higher prevalence rates in every DIS/DSM III diagnostic category compared to domiciled men. Homeless persons reported higher rates of hospitalization than household men for both mental (33 per cent vs 5 per cent) and physical (20 per cent vs 10 per cent) problems but a lower proportion received ambulatory care (41 per cent vs 50 per cent). Social dysfunction among the homeless was indicated by fewer social contacts and higher rates of arrests as adults than domiciled men (58 per cent vs 24 per cent), including multiple arrests (38 per cent vs 9 per cent) and felony convictions (16 per cent vs 5 per cent). Implications of these findings are discussed in terms of research and health policy.     

How did the introduction of managed care for the uninsured in Iowa affect the use of substance abuse services?

Concerns about access under managed care have been raised for vulnerable populations such as publicly funded patients with substance abuse problems. To estimate the effects of the Iowa Managed Substance Abuse Care Plan (IMSACP) on substance abuse service use by publicly funded patients, service use before and after IMSACP was compared; adjustments were made for changes in population sociodemographic and clinical characteristics. Between fiscal years 1994 and 1997, patient case mix was marked by a higher burden of illness and the use of inpatient, residential non-detox, outpatient counseling, and assessment services declined, while use of intensive outpatient and residential detox services increased. Findings were similar among women, children, and homeless persons. Thus, care moved away from high-cost inpatient settings to less costly venues. Without knowing the impact on treatment outcomes, these changes cannot be interpreted as improved provider efficiency versus simply cost containment and profit maximization.     

Who leaves managed behavioral health care?

The growth of managed care and the possibility of biased enrollment and disenrollment rates have raised concerns about cost shifting. This article analyzes the duration of continuous enrollment in a managed behavioral health organization among members with and without behavioral health care utilization and among members with different mental health conditions. Eleven large employers with more than 250,000 members who are enrolled in managed behavioral health plans are studied. Compared to managed care 10 years ago, the rate of disenrollment among patients with depression appears to have dropped. Moreover, there appear few differences in disenrollment among users and nonusers of behavioral health services, except for employees for whom coverage is linked to job performance. However, patients with substance abuse problems or severe types of disorders are significantly more likely to disenroll than patients with less severe problems.     

Health risks and behaviour of out–of–school 16–year–olds in New South Wales

Abstract: This study describes the health risks and health behaviour of a sample of 283 out–of–school 16–year–olds in New South Wales. We sampled study participants through the Commonwealth Employment Service offices in 1994 using a multistage sampling procedure. Of those surveyed, 129 responded to a letter inviting them to participate and 154 were recruited opportunistically. This paper describes the study methods and results for self–reported binge drinking, weekly use of tobacco and marijuana, sexual abuse, physical abuse, drink–driving, violence, and use of health services, by sex and method of recruitment. High rates of substance use were observed. Reported substance use in the out–of–school group was consistently higher than for 16–year–olds in school, except for binge drinking for girls recruited by letter. Of the out–of–school group, 34 per cent reported weekly use of tobacco, marijuana and also binge drinking. Boys were more likely to report drink–driving than girls (28 per cent and 13 per cent respectively). Having been in trouble with police ranged from 32 per cent for girls recruited by letter to 75 per cent for boys recruited opportunistically. A high proportion of girls reported sexual abuse (34 per cent of the 'letter' group and 41 per cent of the 'opportunistic' group). Overall, 87 per cent of respondents had used health services in the previous year. The results indicate that this is a disadvantaged group of young people who are an important target for health service provision and interventions.     

Surveillance of HIV infection and related risk behaviour in European prisons. A multicentre pilot study

BACKGROUND: In order to demonstrate the feasibility of human immunodeficiency virus (HIV) infection and related risk behaviour surveillance in European prisons, a multicentre pilot study was undertaken. METHODS: A cross-sectional survey was carried out in six European prisons (France, Germany, Italy, The Netherlands, Scotland and Sweden). Inmates were invited to complete a self-administered and anonymous questionnaire and to give a saliva sample in order to test for HIV antibodies. RESULTS: Eight hundred and forty-seven out of 1,124 inmates participated in the survey (response rate 75%). Saliva from 817 inmates (73%) was collected and processed for HIV antibodies. Twenty-seven per cent reported that they had ever injected drugs and 49% of these reported they had injected whilst in prison. Eighteen per cent of inmates reported that they had been tattooed whilst in prison, which was found to be higher among injecting drug users (IDUs). One and sixteen per cent reported that they had ever had homosexual and heterosexual intercourse in prison respectively. The HIV prevalence among IDUs was 4% (versus 1% among non-IDUs) (p = 0.02). The proportions of inmates previously tested for hepatitis C and vaccinated against hepatitis B were 24 and 16% respectively. CONCLUSION: This survey demonstrates the feasibility of cross-sectional surveys in European prison inmates and highlights the importance of surveillance of HIV prevalence and related risk behaviour among inmates. The continuing high HIV prevalence and potential for HIV spread in prisons should encourage decision makers in implementing or enhancing harm reduction and education programmes and substance abuse treatment services in prison.     

Addressing substance abuse and violence in substance use disorder treatment and batterer intervention programs

ABSTRACT: BACKGROUND: Substance use disorders and perpetration of intimate partner violence (IPV) are interrelated, major public health problems. Methods: We surveyed directors of a sample of substance use disorder treatment programs (SUDPs; N=241) and batterer intervention programs (BIPs; N=235) in California (70% response rate) to examine the extent to which SUDPs address IPV, and BIPs address substance abuse. Results: Generally, SUDPs were not addressing co-occurring IPV perpetration in a formal and comprehensive way. Few had a policy requiring assessment of potential clients, or monitoring of admitted clients, for violence perpetration; almost one-quarter did not admit potential clients who had perpetrated IPV, and only 20% had a component or track to address violence. About one-third suspended or terminated clients engaging in violence. The most common barriers to SUDPs providing IPV services were that violence prevention was not part of the program's mission, staff lacked training in violence, and the lack of reimbursement mechanisms for such services. In contrast, BIPs tended to address substance abuse in a more formal and comprehensive way; e.g., one-half had a policy requiring potential clients to be assessed, two-thirds required monitoring of substance abuse among admitted clients, and almost one-half had a component or track to address substance abuse. SUDPs had clients with fewer resources (marriage, employment, income, housing), and more severe problems (both alcohol and drug use disorders, dual substance use and other mental health disorders, HIV+ status). We found little evidence that services are centralized for individuals with both substance abuse and violence problems, even though most SUDP and BIP directors agreed that help for both problems should be obtained simultaneously in separate programs. Conclusions: SUDPs may have difficulty addressing violence because they have a clientele with relatively few resources and more complex psychological and medical needs. However, policy change can modify barriers to treatment integration and service linkage, such as reimbursement restrictions and lack of staff training.     

Associated and mediating variables related to quality of life among service users with mental disorders

Purpose

This study aimed to identify variables associated with quality of life (QoL) and mediating variables among 338 service users with mental disorders in Quebec (Canada). Data were collected using nine standardized questionnaires and participant medical records.

Methods

Quality of life was assessed with the Satisfaction with Life Domains Scale. Independent variables were organized into a six-block conceptual framework. Using structural equation modeling, associated and mediating variables related to QoL were identified.

Results

Lower seriousness of needs was the strongest variable associated with QoL, followed by recovery, greater service continuity, gender (male), adequacy of help received, not living alone, absence of substance use or mood disorders, and higher functional status, in that order. Recovery was the single mediating variable linking lower seriousness of needs, higher service continuity, and reduced alcohol use with QoL. Findings suggest that greater service continuity creates favorable conditions for recovery, reducing seriousness of needs and increasing QoL among service users. Lack of recovery-oriented services may affect QoL among alcohol users, as substance use disorders were associated directly and negatively with QoL.

Conclusions

Decision makers and mental health professionals should promote service continuity, and closer collaboration between primary care and specialized services, while supporting recovery-oriented services that encourage service user involvement in their treatment and follow-up. Community-based organizations should aim to reduce the seriousness of needs particularly for female service users and those living alone.

     

Does the disbursement of income increase psychiatric emergencies involving drugs and alcohol?

OBJECTIVE: To determine if the incidence of psychiatric emergencies involving drugs or alcohol supports the argument that mentally ill persons contribute to elevated mortality during the days following disbursement of private earnings and public income transfers. STUDY DESIGN: Interrupted time-series using Box-Jenkins methods. DATA COLLECTION/EXTRACTION METHODS: Daily counts of adults admitted to psychiatric emergency services in San Francisco after using drugs or alcohol were derived from medical records for the period January 1 through June 30, 1997. PRINCIPAL FINDINGS: Psychiatric emergencies among males who had used drugs or alcohol were elevated in the early days of the month. Such emergencies among females were not similarly elevated. Emergencies among females who had not used drugs or alcohol were elevated in the early days of the month. CONCLUSION: Elevated mortality in the first week of the month may be attributable, in part, to the "check effect" or use of drugs and alcohol by mentally ill males in the days after they receive income. The contribution of women is more complex and may be induced by drug or alcohol abuse among persons in their social networks. The check effect suggests that persons with a history of substance abuse and mental illness should be offered the opportunity to have their income managed by someone who can monitor and influence how the money is being spent. The fact that drug- or alcohol-related admissions among males exhibit temporal patterns suggests that the provision of preventive as well as treatment services may be strategically scheduled.     

Associations of substance use, abuse, and dependence with subsequent suicidal behavior

General population survey data are used to disaggregate the associations of substance use disorders with suicide attempts in order to evaluate a number of hypotheses about the processes leading to these associations. Data are from the US National Comorbidity Survey (1990-1992). Discrete-time survival analysis is used to study the effects of retrospectively reported temporally prior substance use, abuse, and dependence in predicting first onset of suicidal behavior. Alcohol and drug use predict subsequent suicide attempts after controlling for sociodemographics and comorbid mental disorders. Previous use is not a significant predictor among current nonusers. Abuse and dependence are significant predictors among users for three of the 10 substances considered (alcohol, inhalants, and heroin). The number of substances used is more important than the types of substances used in predicting suicidal behavior. Disaggregation shows that the effects of use are largely on suicidal ideation and nonplanned attempts among ideators. In comparison, the effects of use on suicide plans and planned attempts among ideators are not significant. Clinicians need to be aware that current substance use, even in the absence of abuse or dependence, is a significant risk factor for unplanned suicide attempts among ideators.     

Long-term follow-up of rural involuntary clients

A cohort of 72 persons who had entered a rural Oregon county's involuntary treatment system in 1979 through 1982 was followed for six years. While schizophrenia was the most frequent diagnosis, several other conditions were represented including adjustment disorders, organic mental disorders, and substance abuse. The majority (55%) of persons with organic mental disorders died as did 12% of the individuals with schizophrenia. The overall mortality rate was three times the expected figure (p=.002). During the follow-up period, only 39% of the initial cohort received treatment from a community mental health program whereas 28% were newly admitted (involuntarily) to a state mental hospital. Hospital recividism was most likely among individuals who had had prior involuntary treatment. At least in rural areas, the civil commitment system seems to serve both “infrequent” and “persistent” users. Infrequent users mainly have diagnoses of adjustment disorders and/or substance abuse. Persistent users chiefly have diagnoses of organic mental disorders, mood disorders, or schizophrenia. Modifying the involuntary treatment system to take account of this heterogeneous population's diverse needs is discussed.     

Toward cost-effective care for persons with dual diagnoses

Implementing services that controlcosts and improve client functioning for persons with both severe psychiatric and substance disorders is paramout in a managed care environment. In this clinical trial, standard mental health care augmented by the behavioral sills intervention was more effective than two other approaches (case management and modified 12-step recovery) in interventions with persons with dual diagnoses across indicators of psychosocial adjustment, psychiatric and substance abuse symptoms, and mental health service costs. These findings reinforce the need to address mental health and substance disorders concomitantly; to provide skill-building interventions as the primary ingredient of active treatment to address various instrumental, coping, and social skill deficits that clients with dual diagnoses have; and to monitor the effectiveness of the services and client progress every six months on multiple adjustment and symptomatology dimensions.     

Equal opportunities, equal risks? Overuse injuries in female military recruits

BACKGROUND: The rate of female personnel medically discharged from service in the British Army has been rising steadily since 1992 from around 3 per 1,000 per year to over 35 per 1,000 in 1996, although there has been only a minor increase in medical discharges for males over the same period. This paper examines the increasing rate of medical discharge in young female members of the British Army from an aetiological perspective and reviews the literature to identify risk factors that may be relevant. METHODS: Data from published military medical statistical reports were reviewed and the clinical records of a 10 per cent sample of females medically discharged for relevant conditions were examined. RESULTS: The majority of the excess medical discharges had occurred in females under the age of 22 and were due to musculoskeletal disorders and injuries caused by military training. Data from the clinical records showed that 75.5 per cent (37/49) of those medically discharged for these conditions were recruits. Stress fractures and other overuse syndromes accounted for 70.2 per cent of medical discharges among the recruits in the sample. CONCLUSION: Females undertaking strenuous exercise alongside males are at increased risk of injury. Risk factors include smoking, short stature, restricted dietary intake and menstrual disturbance. Equal opportunities legislation has been interpreted to require identical training for males and females, but some segregation of training may be acceptable provided the outcome of training is no less favourable to either gender, and this may reduce the excess risk of injury to females.     

Use of hormone replacement therapy by Melbourne women

Abstract: Hormone replacement therapy (HRT) is used for relief of symptoms related to the menopause and for the prevention of postmenopausal osteoporosis and cardiovascular disease. Patterns of use of HRT are thought to be changing rapidly, but little is known about who is using the therapy, for what purpose or for what period of time. Telephone interviews were conducted in May 1991 with a randomly selected sample of 2001 Australian-born women aged 45 to 55 years living in Melbourne, as part of the Melbourne Women's Midlife Health Project. Questions related to use of HRT, health status, use of health services, sexual functioning, attitudes to menopause and aging, and sociodemographic characteristics. Twenty-one per cent of the sample were using HRT. Use was more prevalent among women 50 years and over (28 per cent) than those under 50 (15 per cent). Seventeen per cent of nonhysterectomised women, 31 per cent of hysterectomised women and 49 per cent of women who had undergone hysterectomy and bilateral oophorectomy were current users. Almost 60 per cent had been using the therapy for two years or less, and 34 per cent for one year or less. Just over half reported control of hot flushes as a benefit, and 10 per cent mentioned prevention of bone loss as a benefit Logistic regression analysis identified differences between users and nonusers in experience of hot flushes, health status, use of preventive and treatment services, sexual functioning, wellbeing, attitudes to menopause and aging, and sociodemographic characteristics. These differences may relate to risk of later cardiovascular disease.     

Childhood sexual abuse and age at initiation of injection drug use

OBJECTIVES: We examined the relation between childhood sexual abuse and injection drug use initiation among young adult injection drug users. METHODS: We used mixed effect linear models to compare age at first injection among 2143 young injection drug users by first sexual abuse age categories. RESULTS: The participants were predominantly male (63.3%) and White (52.8%). Mean age and age at first injection were 23.7 and 19.6 years, respectively; 307 participants (14.3%) reported childhood sexual abuse. After adjustment for gender, race/ethnicity, noninjection drug use before first injection drug use, and recruitment site, childhood sexual abuse was independently associated with younger age at first injection. CONCLUSIONS: Childhood sexual abuse was associated with earlier initiation of injection drug use. These data emphasize the need to integrate substance abuse prevention with postvictimization services for children and adolescents.     

Elderly herbal supplement users less satisfied with medical care than nonusers

The purpose of the study was to examine differences between elderly herbal supplement users and nonusers with respect to their perceptions of the safety of supplements and their satisfaction with current medical care. The researchers interviewed 69 elderly persons from congregate meal sites in four Illinois counties to assess herbal supplement use, perceptions of herbal supplement safety, medical supervision of herbal supplement use, and satisfaction with medical care. Two-sample Kolmogorov-Smirnov tests compared both perceived safety of herbal supplements and satisfaction with medical care of supplement users and nonusers. Herbal supplement users were more likely to perceive supplements as safe and to be less satisfied with conventional medical care than nonusers. Some elderly persons do not inform physicians that they are using herbal supplements, thus increasing the risk for supplement misuse, toxicity, and drug-supplement interactions. It is important that physicians, dietetics professionals, and pharmacists inquire about and discuss herbal supplement use with elderly patients.     

Sexual practices,sexually transmitted diseases and other risk factors for HIV among injecting drug users

Abstract: Data were collected from 814 clients attending anonymously for counselling before tests for human immunodeficiency virus (HIV) infection at the Burnett Clinic in Auckland. Just over 10 per cent of clients (n = 83) reported ever having injected drugs. This group was matched according to age, gender, ethnicity and sexual orientation with an equal sized control group drawn from clients who had not injected drugs. The groups were compared in terms of their sexual practices, sexual partnerships, other drug use, current and past health status and their perception of HIV risk. The injecting drug users reported more sex partners than the nonusers, they were less likely to be in a relationship and they were less likely to be monogamous. Vaginal and oral sex were the most common practices in both groups but anal sex was more common among users than the nonusers. Regular condom use was reported by less than a quarter of each group. The health status of drug users was generally poorer than that of the nonusers. They reported greater use of alcohol and other drugs, more mental health problems, and more symptoms of ill health. They also had experienced more sexually-transmitted diseases. Only 1 per cent of users and 2 per cent of nonusers tested positively for HIV, although users saw themselves and their partners as at greater risk of HIV infection than the nonusers.     

Epidemiology and health service resource allocation policy for alcohol, drug abuse, and mental disorders

Data from the NIMH Epidemiologic Catchment Area (ECA) Study in Baltimore, Md., are used to illustrate the association between alcohol, drug abuse, and mental disorder diagnoses with health service use. A probability sample of 3,481 adult (age 18 and over) residents of a geographically defined Baltimore City population of 175,000 was found to have a 23.4 per 100 population, 6-month prevalence of 13 specific alcohol, drug, and mental disorders. Of this population, 7.1 percent sought outpatient mental health treatment from both general medical physicians and mental health specialists in a 6-month period. The presence of a mental disorder diagnosis increased the average number of visits to all health providers from 1.91 to 4.06 during the same 6-month period. Although the presence of a mental disorder diagnosis clearly increased the probability of using both general medical and mental health services, only 15.6 percent of the persons with a mental disorder sought any mental health treatment during this 6-month timeframe--leaving 84 percent of those with mental disorders not seeking any outpatient treatment during the same period. The addition of a measure of high symptomatology (a score of 4 or more on the General Health Questionnaire) increased the percentage of persons with mental disorder using services to 30.5 percent. When a measure of disability was added to the diagnosis and the high symptom level score, 54.7 percent of the population could be predicted to use some mental health service. These data demonstrate the necessity of having additional patient assessment measures with a diagnosis to predict probable service use. However, even in the most comprehensive multidimensional model, more research is required to explore the phenomena of presumed unmet need--the 45 percent of those with a diagnosis, disability, and high symptoms who do not use services. Hence, epidemiologists who wish to participate in setting policy for resource allocation must join with their colleagues in economics, sociology, and health services research to identify all factors in addition to disease states that either predispose population groups to use services or represent additional resource allocation needs.
