Outpatient utilization patterns of integrated and split psychotherapy and pharmacotherapy for depression.

OBJECTIVE: This exploratory study examined utilization and costs among depressed patients in two treatment models-integrated treatment, in which psychotherapy and pharmacotherapy were provided by a psychiatrist, and split treatment, in which pharmacotherapy was provided by a psychiatrist and psychotherapy by a nonphysician psychotherapist. METHODS: A quasi-experimental retrospective design was used to compare claims data from a national managed mental health care organization for 191 patients in integrated treatment and 1,326 in split treatment. RESULTS: During the 18-month study, patients receiving integrated treatment used significantly fewer outpatient sessions and had significantly lower treatment costs, on average, than those in split treatment. Integrated treatment appeared to be associated with a pattern of utilization characterized by frequent treatment episodes in contrast to that of split treatment, which was characterized by more sessions with fewer breaks of 90 days or more. CONCLUSIONS: The results do not support the prevailing assumption that integrated treatment is more costly than split treatment in a managed care network. Despite limitations in the study methods, the strength of these preliminary findings poses a powerful challenge and invites further study.

Self-reported anxiety, general medical conditions, and disability bed days.

OBJECTIVE: This study examined the effect of self-reported anxiety on the number of days persons with various general medical conditions spend in bed owing to disability. METHOD: Self-reported medical illness and disability data from a nationally representative household survey sample (N = 20,884) were analyzed. RESULTS: Among respondents with general medical conditions, those with self-reported anxiety had a nearly fourfold greater length of disability (mean = 18.0 bed days) than the nonanxious respondents (mean = 4.8 bed days). After adjustment for differences in demographic characteristics and burden of general medical illness, anxiety was associated with an additional 3.8 bed days. CONCLUSIONS: Self-reported anxiety in combination with general medical conditions may be associated with extensive functional impairment.

Practice-based research in psychiatry.

OBJECTIVE: The authors describe the APA Practice Research Network (PRN), a national research initiative that ultimately will engage 1,000 practicing psychiatrists in collaborative clinical and services research. The PRN is designed to generate practice-relevant information and to inform future service delivery, policy, and financing decisions pertinent to psychiatry. METHOD: The authors review the relative strengths and limitations of practice-based research compared with other widely used research methods. They also describe the structure of the PRN and its procedures for recruiting network members and for identifying and developing specific network studies. The three primary sources of data for the PRN are 1) the biannual National Survey of Psychiatric Practice, which provides not only a mechanism for randomly recruiting the two-thirds of network participants who are not volunteers but also a baseline for assessing the generalizability of PRN findings; 2) separate biannual studies of psychiatric patients and treatments to characterize the network patient/treatment denominator, which is used to monitor trends in psychiatric practice and plan network studies; and 3) specific studies. RESULTS: Pilot data from the PRN have yielded detailed information on the diagnostic and clinical characteristics of 725 patients and on the treatments provided by network psychiatrists. CONCLUSIONS: The APA PRN offers a powerful complement to traditional clinical and health services research approaches. The PRN will help psychiatry improve its ability to meet patients needs in a context of rapidly evolving scientific and clinical progress and legislative and economic forces affecting health care delivery.

Measuring treatment effectiveness. Part two: Newly emerging outcomes databases for individual practitioners.

Individual practitioners are under pressure from the provider and managed care organizations with which they contract to participate in the provider's outcomes measurement initiatives. While many practitioners respect the potential value of outcomes measurement, they can experience these requirements as burdensome and of little benefit to their own professional work. This section describes two research networks initiated and supported by professional associations. The goals of networks are to address research questions that will advance the field and to give clinicians feedback that is of immediate help in their clinical practice.

Clinical and psychopharmacologic practice patterns of psychiatrists in routine practice.

As part of the American Psychiatric Association's national Practice Research Network (PRN), this pilot study tested a data collection instrument designed to systematically characterize the sociodemographic and diagnostic characteristics of psychiatric patients and the specific treatments they received, including specific psychopharmacologic medications. Ninety-five percent of the PRN members (148 of 156 psychiatrists), who practice in a broad range of settings, completed a 21-page data collection instrument that generated detailed diagnostic, clinical, and treatment data on 290 psychiatric patients. Mood disorders constituted the most common principal DSM-IV diagnostic category, affecting 53 percent of the patients in this pilot study. The majority of patients had significant psychiatric and general medical co-occurring conditions; 20 percent of the patients had at least three DSM-IV Axis I mental disorders. Ninety percent of all patients in the sample received at least one psychopharmacologic medication, with each patient, on average, receiving 1.8 (SD = 1.2). After adjustment for patients' diagnostic and clinical characteristics, the mean number of medications prescribed per patient in this pilot study sample did not vary by health plan type or payment source. However, the combinations of treatments provided by psychiatrists (i.e., psychotherapy and medications) did vary by health plan type and payment source.

Peering into the 'black box'. Measuring outcomes of managed care.

Research on the impact of managed care on access, quality, outcomes, and costs of mental health and substance abuse services has been limited because of the lack of generalizability of studies, the "black box" focus of much of the research, the dynamic changes in mental health and substance abuse managed care, and the proprietary nature of the health care industry. This article provides a framework for understanding the organizational, financial, and procedural features of health plans and the effect of these features on the characteristics and flow of patients through health plans and the selection and utilization of treatments. The diverse research priorities of key stakeholders, i.e., public and private purchasers, managed care organizations, providers, and patients and their families, are described along with a broader societal agenda for delineating the outcomes of health care plans. Critical research and methodologic issues in studying the effects of managed care are outlined, including issues related to identifying and selecting appropriate outcome measures and developing appropriate methods for risk adjustment to adequately control for patient selection bias. This article asserts that government, purchasers, health care plans, providers, consumers, and researchers must collaboratively develop resources and research approaches to fully evaluate the effects of managed care. To realize this objective, auspices with reasonable objectivity are needed along with access to necessary data within the black box of health care systems, a cadre of trained investigators, and sufficient research funding, including the development of an all payers fund to support clinical and health services research.
