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.

Review of pneumococcal endocarditis in adults in the penicillin era.

Streptococcus pneumoniae is an infrequent cause of infectious endocarditis in adults. In the past 2 years, however, we have encountered several cases at our institution, and additional cases have been reported in the literature. This infection typically follows pneumonia in the setting of chronic alcoholism and may additionally be complicated by meningitis. Less commonly, pneumococcal endocarditis occurs in other hosts or follows primary infection at other extrapulmonary sites. In such cases, the diagnosis may be initially missed, with a resultant delay in institution of appropriate therapy. Moreover, there are controversies regarding the optimal therapy for infections of this nature in the era of penicillin resistance. Since a comprehensive review of this topic has not been published since 1990, we reviewed cases of pneumococcal endocarditis in the penicillin era, with particular attention to disease recognition, the role of echocardiography, and the dilemmas surrounding medical and surgical therapeutic interventions.

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.

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.

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.

Predicting the patient at low risk for lymph node metastasis with localized prostate cancer: an analysis of four statistical models.

PURPOSE: Statistical models using preoperative Prostate-Specific Antigen, Gleason primary grade or score of the biopsy specimen, and clinical stage have been developed to predict those patients with clinically localized prostate cancer at low risk for lymph node metastasis. It has been recommended that these patients do not require pelvic lymph node dissections. Four such models were evaluated to assess their accuracy in identifying this subgroup of patients. METHODS AND MATERIALS: We reviewed the records of 214 patients with clinically localized prostate cancer who underwent pelvic lymph node dissections. Data from these patients were entered into the four models. RESULTS: Lymph node metastasis was detected in 14% of patients. The results showed the following for each of the proposed models respectively: 78, 50, 76, and 42% of the patients were identified as low risk and, hence, would be spared pelvic lymph node dissections. The false negative rates are 13 (7.8%), 5 (4.6%), 14 (8.6%), and 1 (1.1%). Sensitivities are 56.7, 83.3, 53.3, and 96.7%. CONCLUSIONS: While the pelvic lymph node dissection is the most accurate method of detecting occult nodal metastasis, statistical models can identify a cohort of low risk patients that may be spared lymphadenectomy.

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.

Subtyping eating disorders: is it justified?

OBJECTIVE: DSM-IV subtypes anorexia nervosa by the presence or absence of bulimic symptoms. Assessing whether bulimic symptoms are related to the probability of recovery can provide justification for subtyping of anorexia. METHOD: Two hundred twenty-five treatment-seeking women with anorexia and/or bulimia nervosa were interviewed every 3 months for up to 4 years. Survival methods were used for analyses. RESULTS: Less than half of the entire cohort recovered; however, the great majority of the women became less symptomatic over time. Contrary to findings from previous studies, bulimic anorexics had a higher rate of recovery than restricting anorexics. CONCLUSION: Differences in course provide some support for the subtyping of anorexia nervosa. Additional prospective studies are needed before subtyping can be warranted.
