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.

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.

Heated humidifiers. Structure and function.

Humidity in the form of molecular water vapor is an essential requirement for intubated patients, and can be beneficial to nonintubated patients receiving CPAP or oxygen therapy. There are many different types of humidification devices but they generally consist of a humidity generator (or water reservoir) and humidity delivery system (or breathing circuit). Humidifiers that generate aerosols may provide adequate humidity, but they also provide a transport mechanism for contaminants and may deliver excess water to the airways. An ideal system generates the required amount of humidity, in the form of water vapor, at the correct temperature, and transports it to the patient without the loss of either heat or moisture. The most effective way to achieve this is to use a large heated water surface for the generator, and heating elements within the delivery system to prevent condensation. This system can be configured to provide optimal humidity for both intubated and nonintubated patients from the neonatal to the adult intensive care unit. Heated humidifiers have no contraindications and can be used on any patient requiring ventilatory assistance or supplemental oxygen.
