Is gender a factor in psychiatrists' evaluation and treatment of patients with major depression?

BACKGROUND: Gender differences in clinical assessment and treatment have been reported in several areas of medicine. We examine whether differences exist in the routine outpatient psychiatric management of men and women with major depression. METHODS: Psychiatrists practicing in the community completed case forms on a systematic sample of their adult outpatients with major depression. Comparisons are presented between male (n=261) and female (n=472) patients focusing on their background characteristics, clinical presentation, assessment, and treatment. Significant gender disparities in assessment and treatment are also examined with respect to the gender of the treating psychiatrist. RESULTS: Although male and female patients had generally similar clinical profiles, a significantly greater proportion of males than females had psychomotor retardation and substance use disorders. No significant gender differences were observed in the assessment of depressive symptoms, psychiatric comorbidities, and treatment with antidepressant medications or psychotherapy. However, a significantly smaller percentage of depressed women than men received assessments of sexual function and medication-related sexual side effects. Female patients were also less likely to have discussed their treatment preferences with their psychiatrists. LIMITATIONS: Only a minority (33.2%) of psychiatrists invited to participate contributed patients to this study. The results are based on structured assessments completed by practicing psychiatrists rather than patient self-assessments or independent research assessments. CONCLUSIONS: Although we find overall little evidence of gender bias in the clinical management of major depression, both male and female psychiatrists need to further explore sexual function and treatment preferences in female patients.

Managed care and fee discounts in psychiatry: new evidence.

This article describes the extent of managed care and fee discounting in psychiatric practice using data on 970 randomly sampled American Psychiatric Association members from the 1996 National Survey of Psychiatric Practice. Seventy percent of psychiatrists were found to have some patients in managed behavioral health care programs. The survey data illustrate that psychiatrists' involvement in managed care spans primary practice settings and is fairly evenly distributed across regions of the United States. Nationally, psychiatrists discount fees for 35% of their patients, with significant variation by practice type and extent of involvement in managed behavioral health care. The average level of discount is 25% with little variation by practice type or extent of involvement in managed behavioral health care. There is little evidence that psychiatrists with patients in managed care have higher fee levels than psychiatrists with no patients in managed care.

Risk-benefit decision making for treatment of depression during pregnancy.

OBJECTIVE: The Committee on Research on Psychiatric Treatments of the American Psychiatric Association identified treatment of major depression during pregnancy as a priority area for improvement in clinical management. The goal of this article was to assist physicians in optimizing treatment plans for childbearing women. METHOD: The authors' work group developed a decision-making model designed to structure the information delivered to pregnant women in the context of the risk-benefit discussion. Perspectives of forensic and decision-making experts were incorporated. RESULTS: The model directs the psychiatrist to structure the problem through diagnostic formulation and identification of treatment options for depression. Reproductive toxicity in five domains (intrauterine fetal death, physical malformations, growth impairment, behavioral teratogenicity, and neonatal toxicity) is reviewed for the potential somatic treatments. The illness (depression) also is characterized by symptoms of somatic dysregulation that compromise health during pregnancy. The patient actively participates and provides her evaluation of the acceptability of the various treatments and outcomes. Her capacity to participate in this process provides evidence of competence to consent. Included in the decision-making process are the patient's significant others and obstetrical physician. The process is ongoing, with the need for incorporation of additional data as the pregnancy and treatment response progress. CONCLUSIONS: The conceptual model provides structure to a process that is frequently stressful for both patients and psychiatrists. By applying the model, clinicians will ensure that critical aspects of the risk-benefit discussion are included in their care of pregnant women.

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.

Psychotherapeutic medication patterns for youths with attention-deficit/hyperactivity disorder.

OBJECTIVES: (1) To describe temporal patterns of office visits for attention-deficit/hyperactivity disorder (ADHD) and stimulant treatment for 5- to 14-year-old US youths; (2) to compare youth visits for ADHD with and without melication according to patient demographics, physician specialty, reimbursement source, and comorbid diagnoses; and (3) to compare office visits for youths with ADHD in relation to common medication patterns (stimulants alone, stimulants with other psychotherapeutic medication, and nonstimulant psychotherapeutic medications alone). DESIGN: Survey based on a national probability sample of office-based physicians in the United States. SETTING: Physician offices. PARTICIPANTS: A systematically sampled group of office-based physicians. MAIN OUTCOME MEASURES: National estimates of office visits for ADHD and psychotherapeutic drug visits for ADHD for each year and for a combined 8-year period. RESULTS: Youth visits for ADHD as a percentage of total physician visits had a 90% increase, from 1.9% in 1989 to 3.6% in 1996. Stimulant therapy within ADHD youth visits rose from 62.6% in 1989 to 76.6% in 1996. While the majority of non-ADHD youth visits were conducted by primary care physicians, one third of ADHD youth visits were managed by psychiatry and neurology specialists. Health maintenance organization insurance was the reimbursement source for 17.9% of non-ADHD youth visits but only 11.7% of ADHD youth visits. Complex medication therapy was more likely to be prescribed by psychiatrists and less likely to be related to visits with health maintenance organization reimbursement. CONCLUSIONS: National survey estimates in the 1990s confirm the substantial increase in visits for youths diagnosed as having ADHD, with more than three quarters of these visits associated with psychotherapeutic medication treatment. Physician specialty and reimbursement source variables identify distinct patient populations with a gradient in psychotherapeutic medication patterns from single-drug standard (stimulant) therapy to complex multidrug treatment regimens for which evidence-based scientific information is lacking.

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.

Therapeutic drug monitoring of mood stabilizers in Medicaid patients with bipolar disorder.

OBJECTIVE: The authors' goal was to determine the extent and pattern of blood serum monitoring of mood stabilizers in Medicaid patients with bipolar disorder. METHOD: Data were drawn from a Medicaid medical claims data set from Pittsburgh and the surrounding region. The authors identified bipolar patients using lithium, valproate, and carbamazepine (N = 718) and then examined the patient demographic, diagnostic, and service use variables associated with therapeutic drug monitoring. RESULTS: A substantial proportion of lithium users (36.5%), valproate users (42.4%), and carbamazepine users (42.2%) with bipolar disorder diagnoses did not receive therapeutic drug level testing during the 12-month study period. Carbamazepine users who were male or in the 30-49-year age range were significantly less likely to be tested for serum drug level. Lithium users who did not receive partial-hospitalization psychiatric services and valproate users who received mental health case management were also less likely to be tested for serum drug level. Over one-half of the lithium users (54.1%) did not receive thyroid function tests, and few (4.2%) received renal function tests. Patients who did receive tests for serum drug level were likely to receive the other recommended tests. CONCLUSIONS: Many Medicaid patients with bipolar disorder received no therapeutic drug monitoring. Patient sociodemographic characteristics contributed little to explaining this omission, although some types of service utilization were related to rates of serum drug level testing.

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.

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.

Antidepressant prescribing practices of outpatient psychiatrists.

BACKGROUND: The authors examined recent changes in the number and proportion of patients prescribed antidepressants by psychiatrists in outpatient private practice and characterized antidepressant prescription patterns by patient age, sex, race, payment source, and clinical diagnosis. METHODS: The authors analyzed physician-reported data from the 1985 and 1993-1994 National Ambulatory Medical Care Survey, focusing on visits to physicians specializing in psychiatry. Logistic regressions were used to examine associations between survey year and antidepressant prescription, adjusting for the presence of other variables. RESULTS: The proportion of outpatient psychiatric visits in which an antidepressant was prescribed increased from 23.1% (95% confidence interval [CI], 19.7%-26.5%) in 1985 to 48.6% (95% CI, 47.5%-49.7%) in 1993-1994. After controlling for several patient variables, psychiatric patients were approximately 2.3 (95% CI, 1.8-2.9) times more likely to receive an antidepressant in 1993-1994 than in 1985. In 1993-1994, selective serotonin reuptake inhibitors accounted for approximately half of the psychiatric visits with an antidepressant prescription. Increases in the rate of antidepressant prescription were particularly evident for children and young adults; whites; new patients; and patients with adjustment disorders, personality disorders, depression not otherwise specified or dysthymia, and some anxiety disorders. CONCLUSIONS: During the late 1980s and early 1990s, there was a significant increase in the prescription of antidepressants by office-based psychiatrists. This increase was greatest for patients with less severe psychiatric disorders.

Assessing the feasibility of recruiting a randomly selected sample of psychiatrists to participate in a national practice-based research network.

This study tested the feasibility of recruiting and retaining a randomly selected sample of psychiatrists compared to a volunteer sample to participate in the American Psychiatric Association's Practice Research Network (PRN). One hundred-forty psychiatrists were randomly selected and contacted by phone by peer psychiatrists for recruitment into the PRN. As a comparison group, a sample of 146 self-selected volunteer psychiatrists were also included in the study. Recruited and volunteer psychiatrists were asked to participate in three studies to assess study compliance and retention. The representativeness of each sample was evaluated by comparing the psychiatrists' sociodemographic and practice characteristics to existing national data on psychiatrists. Study response rates and long-term retention rates were compared for the two groups. Sixty-one percent of the recruited sample who were eligible to participate in the network were willing to participate. Both the recruited and volunteer samples were broadly representative of the American Psychiatric Association's membership (with some differences in race, ethnicity and board certification). Of the recruited sample, 74.5% (38/51) successfully completed the network's first three pilot studies compared to 72.5% (98/135) of the volunteer sample. No psychiatrists in the recruited sample withdrew from the network compared to 2.1% (3/138) of the volunteer sample. These findings indicate a randomly selected sample of psychiatrists can be recruited and retained to participate in practice-based research. These methods can be used to enhance the generalizability of observational health services research studies, which require the participation of practicing clinicians. More effective methods should be tested to enhance participation rates.

The impact of managed care on psychiatry.

It is estimated that 50% of all practicing psychiatrists have at least one contract with a managed care organization (AMA, 1994). As the field of psychiatry increasingly adopts the tools of managed care, it is important for researchers to clarify the extent to which managed care affects the practice of psychiatry, and how the changing practice climate in turn affects patients seeking mental health care. A diverse array of managed care techniques have been introduced into the profession of psychiatry in an effort to alter treatment patterns. One commonly used tool, utilization review, can alter treatment patterns by restricting access to treatment alternatives and providing incentives to practitioners to meet managed care goals. Other managed care tools are the determination of "medical necessity" and the use of triage and treatment guidelines among insured enrollees requesting services. These guidelines serve as selection criteria to help determine not only which members of the insured population receive treatment for mental health care, but also to determine the allocation of enrollees to staff members and to prescribe the starting point for the types of services received. Managed care psychiatrists may find changes not only in their client populations and treatment alternatives, but in many other aspects of their practice. Some psychiatrists working in managed care have become increasingly involved in treatment teams. Other psychiatrists contracting with MCOs are reserved for medication management, consultation, or administration in carved-out mental health departments or agencies. Little is known about the extent to which managed care restrictions affect psychiatrists' patient care roles, collaborative relationships with other mental health professionals, and the degree to which psychiatrists are involved in administration of managed mental health care benefits. The era of managed care has constrained the clinical decision making of psychiatrists whose magnitude and impact on job satisfaction and labor market responses are unknown. Surveys of general physicians in MCOs have provided a framework for understanding some of the difficulties and opportunities faced by managed care psychiatrists, but have failed to shed much light on many aspects of medical practice specific to the provision of mental health care within the boundaries of managed care. Future research in this area would help fill this gap, and assist in shaping the roles of psychiatrists in managed mental health care organizations.

Clinical and treatment characteristics of children with attention-deficit/hyperactivity disorder in psychiatric practice.

OBJECTIVE: To capture information about the clinical characteristics of, and treatments for, children with attention-deficit/hyperactivity disorder (ADHD) in psychiatric practice. METHOD: A mailed, self-administered questionnaire was sent to 81 practicing psychiatrists for them to complete on the next three consecutive patients aged 14 years and younger with ADHD seen during the 12-day study period. Information collected included the sociodemographic, clinical, and treatment characteristics of sampled patients. RESULTS: Patients in the study were predominantly white (85%), male (78%), and between 10 and 14 years old (58%). The most common ADHD subtype was combined/predominantly hyperactive (86%); 31% had no other comorbidity. Ninety-seven percent were receiving medications, with 49% receiving two or more. The single most common medication reported was methylphenidate (51% of patients) followed by clonidine (20%). Psychotropics other than psychostimulants were used in a majority of patients (55%). CONCLUSIONS: Psychiatrists, and child and adolescent psychiatrists in particular, see a more severely impaired and complex group of patients than would be expected of primary care providers. The treatment patterns of psychiatrists for these patients do not reflect the simpler treatments usually studied in clinical trials.

Characterizing psychiatry with findings from the 1996 National Survey of Psychiatric Practice.

OBJECTIVE: The authors' goal was to characterize psychiatric practice by reporting findings from the 1996 National Survey of Psychiatric Practice. METHODS: A random sample of 1,481 APA members was selected to participate in the study; 1,375 APA members were determined to be eligible for study participation. The authors report data from 970 respondents (70.5% response rate) and compare them with data from previous surveys of psychiatrists. RESULTS: Twenty-five percent of the participating psychiatrists were women, compared with 19% in a 1988-1989 survey. Since 1988-1989, the proportion of psychiatrists 39 years old or younger has decreased and the proportion of those 55 years old or older has increased. In 1996, psychiatrists saw, on average, 35.4 unduplicated patients and worked an average of 46.4 hours in a typical week. Patients with mood disorders as their primary diagnoses accounted for the greatest proportion of psychiatrists' caseloads, followed by patients with anxiety disorders, then those with schizophrenia and other psychotic disorders. Public sources of payment and uncompensated care were the main sources of payment for psychiatrists services for 41.7% of patients. The primary payment mechanism for psychiatrists' patient care services was fee-for-service, accounting for 52.5% of psychiatrists' income from direct patient care. Twenty-nine percent of psychiatric patients received care through some form of managed care system, and 41.6% received treatment through a nonmanaged public or private health plan. CONCLUSIONS: As psychiatry moves into the next century, findings from the National Survey of Psychiatric Practice will form a baseline for monitoring changes and trends in the delivery and financing of mental health services.
