Comparing the national economic burden of five chronic conditions.

Using a nationally representative sample of 23,230 U.S. residents, we examine patterns of economic burden across five chronic conditions: mood disorders, diabetes, heart disease, asthma, and hypertension. Almost half of U.S. health care costs in 1996 were borne by persons with one or more of these five conditions; of that spending amount, only about one-quarter was spent on treating the conditions themselves and the remainder on coexistent illnesses. Each condition demonstrated substantial economic burden but also unique characteristics and patterns of service use driving those costs. The findings highlight the differing challenges involved in understanding needs and improving care across particular chronic conditions.

Psychiatric care of patients with depression and comorbid substance use disorders.

BACKGROUND: The goal of this study was to describe the sociodemographic and clinical characteristics and routine psychiatric care of depressed patients with or without substance use disorders (SUDs) and to assess the association between the presence of comorbid SUD and the psychiatric management of patients with depression. METHOD: Each of a sample of 531 psychiatrists participating in the Practice Research Network (PRN) of the American Psychiatric Institute for Research and Education was asked to provide information about 3 randomly chosen patients. Data were collected using a self-administered questionnaire, which generated detailed diagnostic and clinical data on 1228 psychiatric patients. Weighted data were analyzed using the SUDAAN software package. Multivariate logistic regression was used to compare depressed patients with and without SUD. RESULTS: A total of 595 patients (48.4%) were diagnosed with depression (DSM-IV criteria). The prevalence of SUD (excluding nicotine dependence) in this group was 18.1%. The group with SUD had a significantly larger proportion of males, young adults, patients seen in public general hospitals, and non-managed care public plans. No significant group differences were found for primary payer, locus of care, length of treatment, type of current or past treatment, and prescription of medications. Only 2.2% of SUD patients were prescribed with an anti-SUD medication (i.e., disulfiram and naltrexone). CONCLUSION: Concomitant SUDs have little effect on the routine psychiatric care of depressed patients. Efforts should be made to improve the identification and management of depressed patients with SUD.

Understanding disability in mental and general medical conditions.

OBJECTIVE: This study characterized the prevalence, characteristics, and impact of mental and general medical disabilities in the United States. METHOD: The 1994-1995 National Health Interview Survey of Disability was the largest disability survey ever conducted in the United States. A national sample was screened for disability, defined as limitation or inability to participate in a major life activity. Analyses compared cohorts who attributed their disability to physical, mental, or combined conditions. RESULTS: Of 106,573 adults, 1.1% reported functional disability from mental conditions, 4.8% from general medical conditions, and 1.2% from combined mental and general medical conditions. Disabilities attributed to a mental condition were predominantly associated with social and cognitive difficulties, those attributed to general medical conditions with physical limitations, and combined disabilities with deficits spanning multiple domains. In multivariate models, comorbid medical and mental conditions were associated with a twofold increase in odds of unemployment and a two-thirds increase in odds of support on disability payments compared to respondents with a single form of disability. More than half the nonworking disabled reported that economic, social, and job-based barriers contributed to their inability to work. One-fourth of working disabled people reported discrimination on the basis of their disability during the past 5 years. CONCLUSIONS: An estimated three million Americans (one-third of disabled people) reported that a mental condition contributes to their disability. Mental, general medical, and combined conditions are associated with unique patterns of functional impairment. Social and economic factors and job discrimination may exacerbate the functional impairments resulting from clinical syndromes.

Recent patterns and predictors of antipsychotic medication regimens used to treat schizophrenia and other psychotic disorders.

Up-to-date data are needed on the types of treatments used by psychiatrists and the reasons for use of particular treatments. Using 1997 American Psychiatric Association (APA) Practice Research Network (PRN) Study data on patients with schizophrenia and other psychotic disorders, we identified the characteristics of antipsychotic medications (APMs) currently being prescribed and factors associated with the use of particular regimens. In this study population, use of the newer APMs, including risperidone, olanzapine, and clozapine, has increased rapidly and now accounts for over one-half of all APM use. Other intriguing findings include the fact that one-sixth of patients with schizophrenia and other psychotic disorders are concurrently treated with two or more APMs. Factors associated with being prescribed one of the newer APMs risperidone or olanzapine include being elderly, having more education, being white, having psychiatric comorbidity, and making fewer recent visits to a psychiatrist. The APA PRN Study data are an important new resource for mental health services researchers.

Improvement strategies in free-throw shooting and grip-strength tasks.

Participants performed a free-throw shooting task and a grip-strength task before and after imagery, nonspecific arousal, or no instructions. Imagery improved performance in the free-throw shooting task, which is assumed to have more cognitive components than the grip-strength task. Imagery did not improve performance in the grip-strength task, which is assumed to have fewer cognitive components than the free-throw task. Nonspecific arousal, on the other hand, improved performance in the grip-strength task but not in the free-throw shooting task. Athletic experience, confidence levels, and gender were correlated with actual performance levels in both tasks, but not with improvement. Results are discussed within the transfer-appropriate processing framework.

Referrals to psychiatrists. Assessing the communication interface between psychiatry and primary care.

The Study of Outpatient Referral Patterns was conducted in 1998 to examine the nature of the communication relationship between psychiatrists and primary care physicians regarding outpatient referrals. Nationally representative psychiatrists were surveyed (N = 542) regarding their aggregate experience with outpatient referrals from non-psychiatric physicians in the previous 60 days. Data regarding frequency and type of information and mode of communication were gathered. Results indicate that primary care physicians represent a significant source of referrals to psychiatrists and that psychiatrists are generally satisfied with the communication interface with the referring physicians. Psychiatrists' level of satisfaction was related to the quantity and quality of information provided by referring physicians.

Alcohol abuse and dependence in a national sample of psychiatric patients.

OBJECTIVE: To examine clinical characteristics and services being provided to Alcohol Abuse/Dependent (AAD) patients in current psychiatric practice. METHOD: In a national sample of psychiatrists (N = 417), each provided data on three preselected patients (N = 1,245; 51.8% women) that included demographics, DSM-IV diagnoses, treatment setting and health-plan measures. Logistic regression was used to compare patients with and without an AAD diagnosis. RESULTS: Only 12% of patients (n = 151) had an AAD diagnosis. AAD patient care was more frequently subject to utilization review and restriction or specification of medications to be prescribed (formulary). Psychiatrists also perceived greater restrictions on AAD patient care (e.g., requirements to use specific practice guidelines or treatment algorithms). CONCLUSIONS: Findings suggest that health care systems are subjecting treatment patients with AAD to greater scrutiny and may be limiting the extent and nature of care provided to these patients. The low prevalence of AAD among patients being seen by psychiatrists also warrants further attention. Study findings highlight the utility of practice-based research in addiction psychiatry.

Update of geriatric psychiatry practices among American psychiatrists: Analysis of the 1996 National Survey of Psychiatric Practice.

Using data from the 1996 National Survey of Psychiatric Practice from the American Psychiatric Association (APA), the authors updated information on psychiatrists who are high geriatric providers (HGPs). In 1996, HGPs comprised 18% of the sample. Only 23% reported no geriatric patients in their practice, a 51% reduction from 1988-89; the proportion of HGPs is increasing. HGPs were more often male, minority, international medical school graduates, certified in geriatric psychiatry, and not medical school-affiliated. HGPs worked longer hours/week in direct patient care, had more patient visits/week, and saw more new patients/month, spending more time in hospitals and nursing homes and less time in office-based practice, and seeing more patients with mood disorders, psychotic disorders, and other disorders. Medicare was a proportionally higher payment source. Older psychiatrists were likely to have more patients over age 65. Tracking practice activities of HGPs may help inform policy discussion regarding staffing needs for geriatric patients with late-life mental disorders.

Characteristics of health plans that treat psychiatric patients.

Nationally representative data regarding the organizational, financial, and procedural features of health plans in which psychiatric patients receive treatment indicate that fewer privately insured, Medicaid, and Medicare managed care enrollees receive care from a psychiatrist than is true for "nonmanaged" enrollees. Financial considerations were reported to adversely affect treatment for one-third of all patients. Although utilization management techniques and financial/resource constraints commonly applied to patients in both managed and nonmanaged plans, performance-based incentives were rare in nonmanaged plans. The traditional health plan categories provide limited information to identify salient plan characteristics and guide policy decisions regarding the provision of care.

Psychiatric patients and treatments in 1997: findings from the American Psychiatric Practice Research Network.

Despite extensive studies on the epidemiology of mental disorders and advances in the treatment of these conditions, there is a paucity of detailed information concerning the characteristics of psychiatric patients and how treatments are administered in routine psychiatric practice. This 1997 observational study collected detailed information from 417 psychiatrists on the demographic, diagnostic, clinical, and treatment characteristics of a systematic sample of 1228 patients. Six hundred thirty-seven patients (51.9%) were women and the mean patient age was 41.9 years. The most common diagnostic category (53.7%) was mood disorders, followed by schizophrenia/psychotic disorders (14.6%), anxiety disorders (9.3%), and disorders of childhood (7.7%). Six hundred seventy-one patients (54.6%) had at least one comorbid Axis I condition and almost half (49.8%) had a history of psychiatric hospitalization. Patients received a mean of 2.0 psychotherapeutic medications, most commonly antidepressants (62.3%). Findings demonstrate that psychiatrists in routine practice treat a patient population with severe, complex conditions.

Prescribing trends in psychotropic medications: primary care, psychiatry, and other medical specialties.

CONTEXT: Psychotropic medications are widely prescribed, but how new classes of psychotropic medications have affected prescribing patterns has not been well documented. OBJECTIVE: To examine changes between 1985 and 1994 (data from 1993 and 1994 were combined) in the prescribing patterns of psychotropic medications by office-based primary care physicians, psychiatrists, and other medical specialists. DESIGN: National estimates for the number of visits during which a physician prescribed a psychotropic medication based on the National Ambulatory Medical Care Surveys conducted in 1985, 1993, and 1994. SETTING: Office-based physician practices in the United States. PARTICIPANTS: A systematically sampled group of office-based physicians. MAIN OUTCOME MEASURES: National estimates of visits that included a psychotropic medication. RESULTS: The number of visits during which a psychotropic medication was prescribed increased from 32.73 million to 45.64 million; the proportion of such visits, as a proportion of all visits, increased from 5.1% to 6.5% (P< or =.01). Antianxiety or hypnotic drug visits, previously the largest category, decreased as a proportion of psychotropic drug visits (P< or =.01) and are now surpassed by antidepressant visits. Visits for depression increased from 10.99 million in 1988 to 20.43 million in 1993 and 1994 (P< or =.01). Stimulant drug visits increased from 0.57 million to 2.86 million (P< or =.01). Although visits for depression doubled for both primary care physicians and psychiatrists, the proportion of visits for depression during which an antidepressant was prescribed increased for psychiatrists but not for primary care physicians. CONCLUSIONS: The patterns of psychotropic medication use in outpatient medical practice changed dramatically during the study period, especially in psychiatric practice.
