Adherence assessments and the use of depot antipsychotics in patients with schizophrenia.

BACKGROUND: Antipsychotic medications significantly ameliorate the symptoms of schizophrenia, but patients are often noncompliant with these medications. Research evidence supports the use of depot antipsychotics in noncompliant patients. METHOD: Between January 9, 1991, and December 19, 1995, 1307 veterans with schizophrenia or schizoaffective disorder (ICD-9) were enrolled in a study of enhanced psychosocial programming at 14 Veterans Administration Medical Centers. All had a history of high inpatient use. At enrollment, clinicians listed patient medications, rated patient compliance, and completed a Brief Psychiatric Rating Scale (BPRS) and Global Assessment of Functioning (GAF). Patients reported medication side effects. We describe depot antipsychotic use among these patients and examine the relationship between depot use, assessed compliance, and patient characteristics. RESULTS: At enrollment, 18% of patients in this cohort were receiving depot antipsychotics; however, clinicians reported that 49% had been noncompliant with medication in the past year. Depot use varied significantly with treatment site; African Americans were more likely to receive depot antipsychotics and less likely to receive atypical antipsychotics than white patients. Patients on depot and oral agents had similar levels of psychiatric symptoms, but patients on depot antipsychotics were more likely to receive high doses and complain of side effects. CONCLUSION: Clinicians prescribed depot antipsychotics relatively infrequently, despite high rates of noncompliance and high levels of inpatient use. Variation in use with treatment site and ethnic group suggests barriers to implementing research-based recommendations for depot use in noncompliant patients. Quality improvement programs should consider facilitating the appropriate use of depots.

Adolescent injury in the emergency department: opportunity for alcohol interventions?

STUDY OBJECTIVE: Alcohol, the most commonly used substance among adolescents, is frequently associated with injury. Little is known regarding the drinking characteristics of injured adolescents. Such data are critical for developing emergency department interventions to decrease alcohol-related injury among adolescents. We sought to describe the drinking characteristics of injured adolescents and to describe the relationship of injury severity and mechanisms with drinking characteristics. METHODS: This study was a prospective cohort study performed in a university hospital (sampled May 1, 1995, to July 15, 1995) and a large urban teaching hospital (sampled May 1, 1996, to August 1, 1996). The participants were aged 12 to 20 years, presenting within 6 hours of an injury. We performed a saliva alcohol test and self-administered questionnaire. Age, sex, E-code, injury severity score (ISS), and ED disposition were recorded. An alcohol frequency/quantity index was calculated. Descriptive statistics and 95% confidence intervals were calculated. RESULTS: Two hundred sixty-three patients with a mean age of 17 years and a mean ISS of 2.1 (SD 3.5) were recruited. One hundred fifty-two (50%) were males, and 33 (13%) were admitted. Ten (4%) patients had a positive saliva alcohol test response. On average, within the last year, these adolescents had 1.7 adverse alcohol consequences. Sixty percent drank in unsupervised settings, and 36% reported drinking 5 or more drinks in a row. CONCLUSION: Alcohol use/misuse is a substantial problem among injured adolescents regardless of severity or mechanism of injury. ED physicians should consider screening/intervention or primary prevention of alcohol problems for all injured adolescents.

Effectiveness of specialized treatment programs for veterans with serious and persistent mental illness: a three-year follow-up.

This is the first study to test concurrently the effectiveness of four treatment programs for patients with serious mental illness. Three-year outcome data on utilization and functioning demonstrated important positive changes for seriously mentally ill veterans enrolled in specialized, enhanced inpatient and community case management treatment programs, when compared to patients in an enhanced day treatment program or traditional standard care.

The relationship between alcohol problems and health functioning of older adults in primary care settings.

OBJECTIVE: The purpose of this study was to determine the relationship between alcohol use and health functioning in a sample of older adults screened in primary care settings. DESIGN: A cross-sectional study. SETTING: Thirty-seven primary care clinics. PARTICIPANTS: Older adults (n = 8,578; aged 55-97) with regularly scheduled appointments in primary care clinics were screened. MEASUREMENTS: Participants were categorized based on alcohol consumption levels as abstainers, low-risk drinkers, and at-risk drinkers (women: 9 or more drinks/week; men: 12 or more drinks/week). Dependent variables were eight SF-36 health functioning scales. RESULTS: Sixty-one percent of participants were abstainers, 31% were low-risk drinkers, and 7% were at-risk drinkers. ANCOVAs found significant effects of drinking status on General Health, Physical Functioning, Physical Role Functioning, Bodily Pain, Vitality, Mental Health, Emotional Role, and Social Functioning, controlling for age and gender, with low-risk drinkers scoring significantly better than abstainers. At-risk drinkers had significantly poorer mental health functioning than low-risk drinkers. Few significant gender differences were found on SF-36 scales. CONCLUSIONS: Older adults who are at-risk drinkers may not present with poor physical health functioning. Future studies are needed to determine the relationship between drinking limits for older adults and other areas of physical and psychosocial health.

Race and inpatient psychiatric diagnoses among elderly veterans.

OBJECTIVE: Limited data exist on differential rates of psychiatric diagnoses between ethnocultural groups in the elderly population. The purpose of this study was to examine more closely the issue of race and rates of psychiatric diagnoses among elderly inpatients. METHODS: The national sample included 23,758 veterans age 60 or over admitted in 1994 to acute inpatient units in Department of Veterans Affairs (VA) hospitals. Psychiatric diagnosis determined inclusion in one of six diagnostic groups: cognitive, mood, psychotic, substance use, anxiety, and other disorders. The study also assessed rates of psychiatric diagnoses among patients admitted to psychiatric units only and by age group and treatment setting, such as the size of the hospital and whether it had an academic affiliation. RESULTS: Compared with elderly Hispanic and Caucasian patients, a significantly higher proportion of elderly African-American patients were diagnosed as having cognitive disorders and substance use disorders, and a significantly lower proportion were diagnosed as having mood and anxiety disorders. Hispanic and African-American patients had significantly higher rates of psychotic diagnoses than Caucasian patients. For all diagnoses except cognitive disorders, these differential rates were also found among patients admitted to psychiatric units only. Age and treatment setting appeared to moderate some of the differences in diagnostic rates, except for mood disorders. In every analysis performed, the rate of mood disorder diagnoses among elderly African-American patients was less than half the rate among elderly Caucasian patients. CONCLUSIONS: The findings suggest that elderly African-American veterans admitted to VA inpatient units have strikingly lower rates of mood disorder diagnoses. Future studies should examine the contribution of both patient and provider factors to these differences.

Age-group differences in treatment outcomes for male veterans with severe schizophrenia: a three-year longitudinal study.

Treatment outcomes in later-life schizophrenia are poorly understood and of serious concern for clinicians and mental health policy makers. Age-group differences were examined for 499 male veterans with severe schizophrenia enrolled in enhanced treatment programs at 12 Veterans Affairs hospitals. Participants were separated into three age groups (20-39 years, 40-59 years, 60 years and above), with the following outcomes assessed at enrolment and 1 and 3 years afterwards: psychiatric symptomatology, global functioning, impairment in Instrumental Activities of Daily Living (IADL), and hospital use. All three age groups experienced significant improvement in psychiatric symptoms over time. The oldest group fared worse than younger patients in terms of global functioning and generally required more inpatient services and assistance with IADL. Innovative programming is needed to meet the special needs of the growing population of older adults with schizophrenia.

Race, psychiatric diagnosis, and mental health care utilization in older patients.

To evaluate the impact of race on mental health care utilization among older patients within given clinical psychiatric diagnoses, the authors examined a retrospective sample of 23,718 elderly veterans treated in Department of Veterans Affairs inpatient facilities in 1994. Significant racial differences in mental health care utilization found over a subsequent 2-year period were related to outpatient (but not inpatient) care; for instance: 1) African American patients with psychotic disorders had significantly fewer outpatient psychiatric visits; and 2) African American patients with substance abuse disorders had significantly more psychiatric visits than Caucasian patients in their respective groups. Although inpatient utilization appeared to be similar among races, findings related to outpatient utilization may be associated with such factors as compliance, treatment efficacy, access to health care, or possible clinician bias.

Health care utilization by older patients with coexisting dementia and depression.

OBJECTIVE: Few studies have examined the course of coexisting dementia and depression. The purpose of this study was to compare elderly patients who had coexisting dementia and depression with elderly patients who had either disorder alone in terms of their utilization of inpatient and outpatient services. METHOD: The study group included 7,115 veterans aged 60 years or older who had been discharged from Department of Veterans Affairs inpatient units in 1992 with diagnoses of major depression, dementia, or both. Outcome measures were analyzed for a 2-year period following the index hospitalization for each diagnostic study group. RESULTS: Patients with coexisting dementia and depression had significantly more psychiatric inpatient days than the other two study groups and more medical inpatient days and nursing home readmissions than patients with depression alone. Patients with coexisting dementia and depression had significantly more total inpatient days than the other two groups. Notably, patients with coexisting dementia and depression did not utilize more outpatient resources than the other study groups; in fact, they had significantly fewer medical, psychiatric, and total visits than patients with depression alone. CONCLUSIONS: The findings suggest that patients with coexisting dementia and depression are high utilizers of inpatient services, with a course of illness that may resemble dementia in terms of nursing home and inpatient medical care utilization and depression in terms of inpatient psychiatric care utilization; however, these patients utilized significantly fewer outpatient resources than the group with depression alone. Aggressive outpatient treatment approaches might reduce utilization of inpatient care for patients with coexisting depression and dementia.

Repeated assaults by patients in VA hospital and clinic settings.

OBJECTIVE: The study aim was to determine the prevalence of repeated assaults on staff and other patients and characteristics of patients who commit repeated assaults in the Veterans Health Administration of the Department of Veterans Affairs. METHODS: Patients in VA medical centers and freestanding outpatient clinics who committed two or more assaults in fiscal years 1995 and 1996 were identified through a survey of facility quality or risk managers. For each repeatedly assaultive patient, structured information, including incident reports, was obtained for all assault occasions. RESULTS: A total of 153 VA facilities responded, for a response rate of 99 percent. The survey identified 8,968 incidents of repeated assault by 2,233 patients, for a mean of 4.02 assaults per patient in the two-year study period. In 92 percent of the incidents, the assaultive patient had a primary or secondary psychiatric diagnosis. The mean age of the repeat assaulters was 62 years. Ninety-eight percent of the repeat assaulters were male, and 76.6 percent were Caucasian. At least 16 percent of the assaulters, 22 percent of the patients assaulted, and 20 percent of the staff assaulted required medical attention for injuries, which, along with the number of lost work days, indicates that repeated assaults are costly. CONCLUSIONS: Repeatedly assaultive patients represent major challenges to their own safety as well as to that of other patients and staff. Identifying patients at risk for repeated assaults and developing intervention strategies is critically important for ensuring the provision of health care to the vulnerable population of assaultive patients.

Twelfth grade follow-up of the effectiveness of a middle school-based substance abuse prevention program.

A twelfth-grade follow-up afforded the opportunity to assess the long-term effects of substance abuse prevention delivered in sixth and seventh grades. A social pressures resistance skills curriculum implemented by classroom teachers had been evaluated with short-term positive results previously reported. Students completed self-administered questionnaires at sixth grade pre- and posttests, and at seventh and twelfth-grade posttests. Curriculum group students received lessons on alcohol, tobacco (cigarettes and smokeless), marijuana, and cocaine, which were later incorporated into the Michigan Model for Comprehensive School Health Education. This evaluation used data from 262 students who completed all four questionnaires and who received the complete two-year intervention or no intervention. Repeated measures analyses of variance demonstrated that significant effects evident at seventh grade for alcohol use and misuse, as well as cigarette, cocaine, and other drug use were generally not maintained through twelfth grade. Ongoing reinforcement of effective prevention is recommended.

Prevalence of and factors associated with current and lifetime depression in older adult primary care patients.

BACKGROUND: Depression in late life is a significant health problem in the United States. This study examined the relationship between depression and alcohol, cigarette use, family history, and sociodemographic factors in older adult primary care patients. METHODS: As part of a larger clinical trial, 2,732 patients in 24 primary care offices were recruited to complete a self-administered health screening survey. Depression was assessed using Diagnostic and Statistical Manual of Mental Disorders, Third Edition, Revised (DSM-III-R) criteria for lifetime and current depression. RESULTS: A total of 17.8% of females and 9.4% of males age 60 and over met DSM-III-R criteria for lifetime depression; 10.6% of the females and 5.7% of the males met current depression criteria. Depression was significantly and positively correlated with female gender and family history of mental health problems and negatively correlated with social contact. CONCLUSIONS: Older adults, especially women, should be considered at elevated risk for depression when a family history of mental health problems and self-report of inadequate social connection can be established.

Conduct disorder and antisocial personality in adult primary care patients.

BACKGROUND: Conduct disorder has been linked to substance use disorders in clinical populations. This study examined the relationships of conduct disorder and antisocial personality (ASP) disorder to substance use, substance abuse problems, depression, and demographic factors in primary care settings. METHODS: As part of a larger clinical trial, a survey of 1898 patients in the offices of 64 primary care physicians was conducted using a self-administered health habits questionnaire. Childhood conduct disorder and adult antisocial personality disorder were assessed using criteria from the Diagnostic and Statistical Manual of Mental Disorders, Third Edition, Revised. RESULTS: Eight percent of men and 3.1% of women met criteria for a diagnosis of ASP disorder. The frequency of a history of childhood conduct disorders was higher, with 13.4% for men and 4% for women. Antisocial personality disorder was predicted by male sex, being unmarried (single, separated, divorced), lifetime history of depression, binge drinking, self-reported history of drug problems, current smoking, and younger age. The predictors of a history of child conduct disorder were similar to those of ASP. CONCLUSIONS: Primary care physicians treat many patients who have personality disorders and other conditions such as alcohol problems and depression. These patients need to be identified because of the high potential for comorbidity and the barriers to treatment inherent in these disorders.

Effectiveness of a high school alcohol misuse prevention program.

An alcohol misuse prevention curriculum for tenth-grade students was developed, implemented, and evaluated through twelfth grade with 1041 students from four school districts. The curriculum emphasized social pressures resistance training, immediate effects of alcohol, risks of alcohol misuse, and social pressures to misuse alcohol. There were desirable program effects on alcohol misuse prevention knowledge (p < 0.001), alcohol misuse (p < 0.02), and refusal skills (p < 0.09). Gender by occasion differences were found on alcohol use, alcohol misuse, and driving after drinking, with boys' rates increasing more than those of girls. Exposure to a sixth-grade, as well as the tenth-grade, program did not result in better outcomes. Despite high levels of alcohol use among high school students, a tenth-grade curriculum can result in some desirable effects. Creative approaches are needed, however, especially for boys who tend to use and misuse alcohol at rates that increase more steeply than those of girls.

Factors in adolescent drinking/driving: binge drinking, cigarette smoking, and gender.

During three consecutive years, 3,137 high school seniors from three graduating classes in one Michigan county were surveyed. The primarily White sample reported their use of alcohol and cigarettes, driving experience, and drinking/driving experience. Survey data were linked with state driver history records. Fully one-third of the high school seniors reported driving after drinking in the past six months. To identify factors associated with self-reported drinking/driving, correlation and regression analyses were conducted. Frequent binge drinking and riding with a drinking driver were consistent factors in driving after drinking frequency. Being male, smoking cigarettes, having frequent use of a motor vehicle, having a driving offense on record, and number of years licensed were important correlates, varying by year of graduation. Comprehensive interventions to moderate drinking, smoking, and driving after drinking are needed.

Effectiveness of a school-based substance abuse prevention program.

A grade five through eight substance abuse prevention program, later incorporated into the Michigan Model for Comprehensive School Health Education, was developed, implemented, and evaluated. Results focus on students who received seven lessons on alcohol in grade six, and eight lessons on tobacco, alcohol, marijuana, and cocaine in grade seven taught by their regular classroom teachers (after a 6-hour training in the social pressures resistance skills curriculum). Students (N = 442) received either two years of the program or none, and completed individually-coded questionnaires. Repeated measures analysis of variance resulted in significant treatment by occasion interactions on the use of alcohol, cigarettes, marijuana, cocaine, and other drugs, as well as on knowledge. At the end of grade seven, program students' rates of substance use had increased significantly less and knowledge of alcohol pressures, effects, and skills to resist had increased significantly more than those of comparison students.

Measurement of alcohol use and misuse in a cohort of students followed from grade 6 through grade 12.

In following a cohort of students from grade 6 through grade 12 for the purpose of evaluating an Alcohol Misuse Prevention Study curriculum, a substudy of the measurement of alcohol use and misuse was conducted. The 6-year follow-up of young people over time afforded a good opportunity to assess the adequacy of the initially chosen measures to 1) provide data with statistically desirable properties, and 2) be sensitive to and representative of the wide range of alcohol use and misuse patterns among adolescents as they mature. Revised measures of alcohol use and misuse were developed from the data responding to the same questionnaire items that had been used throughout the study. The revised measures demonstrated good psychometric properties and may be useful in other studies.

Assessment of adolescent refusal skills in an alcohol misuse prevention study.

Although many substance abuse prevention programs seek to enhance the ability of adolescents to refuse offers of alcohol and other drugs, few report assessments of refusal skill ability or its relationship to substance use. This report describes a procedure to assess the ability of adolescents to refuse the offer of a beer, and presents the findings of those assessments as well as their relationships to alcohol misuse prevention knowledge, susceptibility to peer pressure, internal health locus of control, self-esteem, and alcohol use and misuse. A one-third random sample (n = 1012) of 10th graders participating in a longitudinal evaluation of an alcohol misuse prevention curriculum was assessed individually. Students rated their own refusals, which were also rated by trained female and male raters. The results indicated that adolescents refuse the offer of a beer only somewhat convincingly. Those adolescents with better refusal skills had higher levels of alcohol misuse prevention knowledge, especially regarding resisting pressures to use alcohol and the application of knowledge of typical alcohol-related situations. They also reported less susceptibility to peer pressure, greater internal health locus of control and self-esteem, and less alcohol use and misuse. The results provide support for teaching refusal skills in substance abuse prevention programs and for assessing refusal skills in the evaluation of such programs.

Longitudinal assessment of inpatient use and functioning of seriously mentally ill veterans with and without co-occurring substance use disorders.

The purpose of this study was to delineate differences in inpatient service utilization and functional and subjective outcomes between veterans with a serious mental illness (SMI) and those with co-occurring serious mental illnesses and substance abuse (SA) disorders. This study assessed 2-year inpatient utilization and outcomes for 682 SMI veterans enrolled in specialized psychosocial treatment programs which did not have a substance abuse focus. Outcomes included psychiatric symptomatology, impairment in activities of daily living, global life satisfaction, days of hospitalization per year, and number of hospital admissions per year. Of the 682 patients, 198 (29%) had secondary diagnoses of substance abuse/dependence. Patients with co-occurring serious mental illness and substance use disorders had significantly more inpatient admissions per year than other SMI patients but did not differ in cumulative inpatient stays. The SMI/SA patients improved more than the other patients in terms of clinician rating of Global Assessment of Functioning. Patients with SMI/SA had significantly fewer psychiatric symptoms on the Brief Psychiatric Rating Scale, and all patients showed improvement on the BPRS, instrumental activities of daily living, and general life satisfaction rating. Seriously mentally ill patients with co-occurring substance use disorders fared as well as other SMI patients when enrolled in intensive, specialized state-of-the-art treatment programs.
