[Survey on the actual condition of psychiatrists and psychiatric services in Japan. (Part 1): Basic data on number and distribution of psychiatrists].

BACKGROUND: To ensure that psychiatric services adequately meet the needs of the Japanese people, planning a prospective design based on a needs analysis is required. Presently, the distribution of medical resources in Japan is skewed and the priorities of psychiatric services are unclear. OBJECTIVE: To determine the current status of psychiatric services. METHOD: The definition of a psychiatrist was determined by qualified specialists of the Japanese Society for Psychiatry and Neurology (JSPN). Of the 11,169 candidates who applied for the specialist psychiatry examination, 246 were excluded due to a lack of personal information and 4 due to refusal. The remaining 10,919 agreed to allow the verification of their personal data. This study was conducted with the approval of the JSPN. The total number of psychiatrists, their demographic backgrounds, the number of psychiatrists by prefecture, and the number of psychiatrists in each secondary medical care block in Japan were calculated. RESULTS: Of the 10,919 psychiatrists included in this analysis, 2,124 were female and 8,790 were male. Approximately 90% were < 65 years old, and 42% were < 45 years old. Their primary work places were as follows: psychiatric hospitals (n = 5,233, 47.9%); university departments of psychiatry (n=1,353, 12.4%); general hospitals (n = 1,064, 9.7%); psychiatric clinics (n = 2,456, 22.5%); nonpsychiatric clinics (n = 687, 6.3%); and nonclinical work places such as basic science departments (n = 124, 1.1%). The number of psychiatrists per 100,000 inhabitants in each prefecture was determined. The highest numbers of psychiatrists were from Kochi (13.20), Tokyo (12.76), and Tokushima (12.24), and the lowest numbers were from Ibaraki (5.34), Aomori (5.36), and Saitama (5.67). The number of psychiatrists per 100,000 inhabitants in Kochi was 1.48 per area (100 km square), and Tokyo showed the highest at 75.99 psychiatrists per area, followed by Osaka and Kanagawa. The five Tohoku prefectures and Hokkaido had the fewest psychiatrists per area. CONCLUSION: For planning the future management of psychiatric services, continuous investigation of the actual number of psychiatrists and the status of psychiatric services in Japan is required with the constant cooperation of the JSPN.

[Survey on the actual condition of psychiatrists and psychiatric services in Japan. (Part 2): Change in geographical working area and setting of each psychiatrist].

BACKGROUND: The shortage of psychiatrists has recently become a public concern; however, the reason for this shortage has not been clearly discussed or explained on the basis of real data. We assumed that it is not only due to the lack of the absolute number of psychiatrists, but also due to an imbalance in their distribution in geographical working areas and settings. OBJECTIVE: To evaluate the change in distribution of Japanese psychiatrists. METHOD: We analyzed the change in the geographical working area and setting of each psychiatrist from September 2006 to March 2009 using data obtained from psychiatrists who applied for the Board Certification Examination of the Japanese Psychiatric Association. Our data included 6,881 psychiatrists. RESULTS: With regard to the geographical working area, the number of psychiatrists in ordinance-designated cities (urban areas) increased by 2.2%, whereas that in other areas decreased by 3.0%. On examination of work settings, we noted a 16.0% decrease in the number of psychiatric departments in general hospitals and a 20.0% increase in the number of psychiatric clinics. Surprisingly, more than 10% of middle-aged psychiatrists (10.3% of 36 45-year-olds and 12.2% of 46-55-year olds) who worked in general hospitals moved to clinics. CONCLUSION: The present study revealed that, although psychiatrists did not tend to move from rural to urban areas, they showed a tendency to move from general hospitals to psychiatric clinics.
