National trends in the use of outpatient psychotherapy.

OBJECTIVE: This article reports recent trends in the use of outpatient psychotherapy in the United States. METHOD: Data from the household sections of the 1987 National Medical Expenditure Survey and the 1997 Medical Expenditure Panel Survey were analyzed. Trends in the rate of psychotherapy use from these nationally representative samples are presented by age, sex, race/ethnicity, marital status, education, employment status, and income. Psychotherapy users are compared over time by provider specialty, concomitant psychotropic medication use, number of annual visits, and costs. In addition, trends in payment source and primary diagnosis are assessed for psychotherapy visits. RESULTS: Between 1987 and 1997, there was no statistically significant change in the overall rate of psychotherapy use (3.2 per 100 persons in 1987 and 3.6 per 100 in 1997). However, significant increases were observed in psychotherapy use by adults aged 55-64 years and by unemployed adults. Among psychotherapy patients, there was a marked increase in the use of antidepressant medications (14.4% to 48.6%), mood stabilizers (5.3% to 14.5%), stimulants (1.9% to 6.4%), and psychotherapy provided by physicians (48.1% to 64.7%). A smaller proportion of patients made more than 20 psychotherapy visits in 1997 (10.3%) than in 1987 (15.7%). Over this period, psychotherapy visits for mood disorders became more common. In 1997, 9.7 million Americans spent $5.7 billion on outpatient psychotherapy. CONCLUSIONS: From 1987 to 1997, access to psychotherapy in the United States remained constant overall but was characterized by increased use by some socioeconomically disadvantaged groups. However, the number of visits per user markedly decreased during this period. Psychotherapy was increasingly administered by physicians and provided in conjunction with psychotropic medications. These changes occurred during a period of expansion in the number of available psychotropic medications and growth in managed behavioral health care.

Trends in the treatment of bipolar disorder by outpatient psychiatrists.

OBJECTIVE: This study examined recent changes in the prescribing patterns for medications to treat bipolar disorder in office-based psychiatric practice. METHOD: The authors analyzed physician-reported data from the National Ambulatory Medical Care Survey for 1992-1995 and 1996-1999, focusing on physicians specializing in psychiatry. Demographic, clinical, and medication prescription characteristics of patients' visits were compared to identify changes between the periods. Logistic regression models were used to identify predictors of medication prescription, with adjustment for the presence of other covariates. RESULTS: In both survey periods, over one-third of the total psychiatrist visits by patients with bipolar disorder did not include prescription of a mood stabilizer. There was a decrease in the use of lithium over time, accompanied by an increase in the use of valproic acid. Antipsychotic medication was prescribed more frequently for the bipolar manic and mixed subtypes, and there was a secular increase in the use of the newer antipsychotics. During each time period, prescription of antidepressants was common, often in the absence of a mood stabilizer. CONCLUSIONS: Despite important advances in the range of mood stabilizers available, the pharmacological treatment of bipolar disorder continues to be an area with substantial opportunity for quality improvement.

Predicting incarceration of clients of a psychiatric probation and parole service.

OBJECTIVE: This study assessed the extent to which clinical characteristics, psychiatric status, and use of mental health services explain incarceration for technical violations of probation or parole rather than incarceration for new offenses. METHODS: A total of 250 clients of an urban psychiatric probation and parole service were screened for psychiatric diagnoses and monitored with a 12-month data collection protocol. Longitudinal analysis was used to explain incarceration on new charges, incarceration on technical violations of probation and parole, or absence of incarceration. RESULTS: Eighty-five individuals (34 percent) were incarcerated during the follow-up period. Forty-four (18 percent) were incarcerated for a new offense, and 41 (16 percent) were incarcerated for a technical violation. Participation in mental health treatment was associated with a lower risk of incarceration for a technical violation. Intensive monitoring by mental health providers, such as through case management and medication management, were significant risk factors for incarceration for a technical violation. Clients who were incarcerated for a technical violation were more than six times as likely to have received intensive case management services. CONCLUSIONS: The role of mental health services in reducing the risk of incarceration remains mixed. Providing services that emphasize monitoring tends to increase the risk of incarceration for technical violations of criminal justice sanctions. However, any participation in treatment and motivation to participate in treatment appears to reduce the risk of incarceration.

Prescription of antipsychotic drugs by office-based physicians in the United States, 1989-1997.

OBJECTIVE: This study examined trends in the prescription of antipsychotic drugs in a nationally representative sample of physicians in nonfederal office-based clinical practice during the 1990s. METHODS: The authors analyzed physician-reported data from annual National Ambulatory Medical Care Surveys between 1989 and 1997 using weighted national estimates of physician visits during which antipsychotic drugs were prescribed. Prescription rates for antipsychotic drugs were compared between periods and among demographic, organizational, and clinical subgroups. RESULTS: Prescription of antipsychotic drugs in office-based practice increased significantly between 1989 and 1997. In 1989 antipsychotics were prescribed during 3.2 million office visits (.46 percent of all visits), compared with 6.9 million visits in 1997 (.88 percent). The atypical antipsychotics risperidone and olanzapine were the most widely prescribed antipsychotics in 1997. Risperidone was prescribed during 22.8 percent of all visits that involved prescription of an antipsychotic, and olanzapine during 17.1 percent. Psychiatrists were more likely than other physicians to prescribe an atypical agent (37.1 percent of visits involving prescription of an antipsychotic compared with 14.2 percent). Psychiatrists were also more likely than other physicians to schedule a follow-up visit after prescribing an antipsychotic (96.6 percent of visits compared with 73 percent). No evidence was found of a broadening of diagnostic indications for use over time. CONCLUSIONS: The rate of prescription of antipsychotic drugs among office-based physicians increased sharply during the 1990s after a nine-year decline. The increase was accounted for by growth in the use of atypical antipsychotics; the overall prescription rate of conventional agents did not change. Psychiatrists were more likely to prescribe atypical agents and to monitor more closely patients who were taking antipsychotics.

National trends in nonoperative care for nonspecific back pain.

BACKGROUND CONTEXT: Few empirical data are available that document changes in population-based rates for the evaluation and treatment of nonspecific back pain. PURPOSE: To determine the extent of change in the pattern of outpatient evaluation and treatment of nonspecific low back pain in the United States between 1987 and 1997. STUDY DESIGN AND SETTING: The 1987 National Medical Expenditure Survey and the 1997 Medical Expenditure Panel Survey, two nationally representative surveys with similar sampling methods and questions, were used. PATIENT SAMPLE: Noninstitutionalized adults in the United States. OUTCOME MEASURES: Changes in rates of any health service for nonspecific back pain and occurrence of provider-specific care and types of services provided. Changes in the prescription of specific medication classes (ie, nonsteroidal anti-inflammatory drugs [NSAIDs], muscle relaxants, nonnarcotic and narcotic analgesics) were also investigated. RESULTS: Overall rate for outpatient treatment for nonspecific back pain in the US population was relatively stable over the decade (4.48% in 1987, 4.53% in 1997, p=.85). Among those receiving care, the proportion receiving physician care increased from 64% in 1987 to 74% in 1997 (p<.001), whereas those obtaining care from physical therapists increased from 5% to 9% during the same time period (p<.01). The proportion of respondents receiving NSAIDs, muscle relaxants, nonnarcotic analgesics and narcotic analgesics remained stable. However, the mean number of patient visits in which these medications were prescribed increased from 2.0 to 3.9 over the decade (p<.001). The proportion of individuals receiving chiropractic care (p<.01) and X- rays (p<.001) were lower in 1997 than 1987. CONCLUSIONS: The national pattern of health care for nonspecific low back pain observed in the present study serves as a basis for future investigations into the management of this major public health problem. Findings suggest that perhaps a duplication of care is partly responsible for the high degree of health care utilization in this population.

Demographic and practice characteristics of psychiatrists who primarily treat patients with substance use disorders.

This study examined the sociodemographic and practice characteristics of psychiatrists whose caseloads consist primarily of patients with Substance Use Disorders (SUD). A survey instrument was completed by a random sample of 865 psychiatrists. Study groups were defined as high-SUD providers if psychiatrists reported having 51% or more patients with SUD (n=92) and non-SUD providers as those who reported not having any patients with SUD (n=128). High-SUD providers tended to be younger, more likely to graduate from international medical schools, have larger caseloads, work more hours per week, and have a higher proportion of inpatients and publicly funded patients than non-SUD providers. Results suggest that psychiatrists who primarily treat patients with SUD are in their early careers and treat patients with more clinical, psychosocial, and economic disadvantages. The implications of these findings for psychiatry training programs and policy makers will be discussed.

Treatment compliance in patients with comorbid psychiatric and substance use disorders.

This study examines clinical and non-clinical factors associated with treatment compliance problems in 342 patients with substance use disorders (SUD) seen in routine psychiatric practice. Weighted Wald-X(2) and multivariate logistic regression assessed sociodemographic, clinical, treatment, and health plan characteristics associated with treatment compliance problems. Among patients with SUD, 40.5% were reported to currently have treatment compliance problems. Patients with treatment compliance problems were significantly more likely to have personality disorders, lower global assessment of functioning scores, and medication side effects than those without treatment compliance problems. Patients seen by psychiatrists who were reimbursed by discounted rather than undiscounted fee-for-service were five times more likely to be reported to have treatment compliance problems. Both clinical and non-clinical factors appear to be associated with treatment compliance problems. Understanding these factors and targeting treatment interventions may improve treatment compliance and patient outcomes.

Medical errors in psychiatry.

Medical errors in the general medical sector result in significant patient deaths and injuries, as well as high costs to the health care system. Despite the growing literature on errors in medical and surgical specialties, few studies have examined the incidence, nature, predictors, and prevention of errors that may occur in mental health treatment settings. The purpose of the current review is to examine the lessons learned from patient-safety research in the general medical sector, provide examples of types of errors in psychiatry, review the errors identified in the literature, offer a discussion of error-reduction strategies for improving patient safety, and provide recommendations for future research. Increased attention to medical errors in psychiatry is necessary in order to build safer health systems and promote a culture of safety among providers, thereby producing better care for patients with mental disorders.

The most expensive medical conditions in America.

This study uses a nationally representative survey to identify the most expensive conditions in the United States and to examine the association between spending and disability. The most expensive conditions at a population level were ischemic heart disease and motor vehicle accidents; at the per capita level they were respiratory malignancies. There was not a significant association between rank order of treatment costs and disability; the conditions with the greatest disability relative to expenditures were mood disorders, chronic obstructive pulmonary disease, and arthropathies. We use the findings to discuss the role for cost-of-illness and burden-of-disease estimates in setting priorities.

Listening to generic Prozac: winners, losers, and sideliners.

This study tracks the diffusion of generic fluoxetine after its release in August 2001 within the largest U.S. pharmacy benefit manager (PBM). Within two weeks of the generic's release, prescriptions exceeded those of brand-name Prozac. The main winners proved to be Barr Laboratories, the first entrant to the generic market; large purchasers, who reaped substantial cost savings after Barr's period of exclusivity expired; and the PBM. The major loser was Eli Lilly, the manufacturer of Prozac. Consumers and makers of other antidepressants largely remained on the sidelines, with surprisingly little short-term impact evident from Prozac's patent expiration.

Comparison of adult and geriatric psychiatric practice patterns: findings from the American Psychiatric Association's Practice Research Network.

OBJECTIVE: The authors explored diagnostic and treatment patterns for patients under and over age 65 seen by a nationally representative sample of psychiatrists participating in the American Psychiatric Association's Practice Research Network. METHODS: Detailed patient information, including demographic and financial characteristics, diagnoses, service utilization, and treatment, was collected by 383 psychiatrists on 1,026 patients to assess the impact of patient age on pharmacotherapy and psychotherapy service use as well as treatment outcomes. RESULTS: Approximately 15% of the patient sample was over age 65. Compared with patients ages 19-64, a lower percentage of geriatric patients had Axis I comorbidity, but a higher percentage had Axis III comorbidity. Geriatric patients were more often treated in hospital settings, and older patients were less likely to have their visits adversely affected by financial pressures of the healthcare system. Over 60% of patients in both age-groups received antidepressants, but there was a disproportionately increased use of antipsychotics and antianxiety/benzodiazepine medications among geriatric patients. Being age 65+ was a strong predictor for "improved" clinician rating on general assessment scores, but failed to be a predictor of receiving psychotherapy or pharmacotherapy. CONCLUSION: There were important differences between subject groups. Overall, American psychiatrists treat a complex group of geriatric patients suffering from major mental disorders complicated by medical comorbidity. Additional studies would further enhance our understanding of the delivery of mental health services to elderly patients and improve training of psychiatrists who help care for our aging population.

Comparing clinical practice with guideline recommendations for the treatment of depression in geriatric patients: findings from the APA practice research network.

OBJECTIVE: The authors describe treatments provided for depressed geriatric patients (age 65+) treated by psychiatrists in the American Psychiatric Association's (APA) Practice Research Network (PRN) and compare treatments with recommended guidelines for treating late-life depression. METHODS: Detailed demographics, diagnoses, service utilization, and treatment information were collected on relevant patients treated by psychiatrists participating in the APA's PRN during 1997, sample-weighted to produce nationally representative estimates. Treatment data were qualitatively compared with existing depression treatment guidelines from the APA and the Expert Consensus Guideline Series on pharmacotherapy of depressive disorders in older patients. RESULTS: Of patients treated by psychiatrists in the PRN (N=152), just over 41% had a diagnosable depressive disorder, and, of those with depression, nearly 84% had major depression. Over 90% received a psychotropic medication, and over 75% received an antidepressant. Treatment intensity, as measured by visit frequency and duration of treatment, were more intense than typically found in primary care. Most patients received a combination of medication management and psychotherapy. Selective serotonin reuptake inhibitors were the most frequently prescribed antidepressant, although they were less frequently prescribed than in primary care and other national surveys. Just over 11% received a tertiary amine antidepressant, and nearly 43% received benzodiazepines, this frequency being inconsistent with existing guidelines. CONCLUSION: Depressed geriatric patients treated by psychiatrists in APA's PRN receive active treatments largely consistent with existing guidelines, which generally resulted in favorable patient outcomes.
