Factors Associated with Turnover Intention among Nurses in Small and Medium-Sized Medical Institutions

Objectives: The objective of this study was to evaluate factors associated with turnover intention among nurses in small and medium-sized medical institutions. Methods: A self-administered questionnaire survey was performed in 293 registered nurses, licensed practical nurses, and assistant nurses working full-time in various medical institutions. Multiple linear regression analysis was conducted, with turnover intention as the dependent variable, and nurses’ basic attributes and job satisfaction as independent variables. Results: As for nurses’ basic attributes, turnover intention was significantly associated with registered nurses, younger nurses and those with low satisfaction with sleep. As for nurses’ job satisfaction, the number of nurses with turnover intention was significantly higher for those with low satisfaction with salary, low satisfaction with welfare, poor implementation of fair salary raise and poor cooperation among nurses. Conclusion: Turnover intention may be reduced by the enhancement of trust in the organization, giving appropriate advice to young nurses and registered nurses, and developing measures for addressing sleep disorders.

Preferred Information Media for Providing Clinical Practice Guidelines to Physicians in Japan : A Needs Assessment Study by the Medical Information Network Distribution Service (Minds) / General Medicine

BACKGROUND: The purpose of our study was to compare the characteristics of medical practitioners who prefer using the Internet as their information resource and those who prefer using printed materials.<BR>METHODS: From December 2002 to January 2003, a non-anonymous questionnaire was sent out by post to members of the Japanese Medical Association (JMA) and physicians working in hospitals. Contributing factors were examined by using logistic regression analysis.<BR>RESULTS: The response rates for the questionnaires were 18.7% (n=1868) for JMA physicians and 68.0% (n=5901) for hospital physicians. Factors associated with the preference for using the Internet were: ‘younger age’; ‘use of the Internet to solve clinical problems and uncertainties’; ‘use of personal computers at work’; and, ‘use of personal computers at home’.<BR>CONCLUSION: The results of this study show that, although some younger physicians prefer printed materials, providing medical information via the Internet is better suited for younger physicians who are making full use of computers. In contrast, older physicians prefer printed materials because they tend to be less familiar with using computers and may have limited accessibility to the Internet. Therefore, using both the Internet and printed materials to provide medical information is necessary to meet the needs of the larger physician population.

The cytotoxicity of microglass fibers on alveolar macrophages of fischer 344 rats evaluated by cell magnetometry, cytochemisry and morphology

<p><b>OBJECTIVES</b>The toxicity of microglass fibers (MG), one of the man-made mineral fibers, has not been sufficiently evaluated.

The Cytotoxicity of Microglass Fibers on Alveolar Macrophages of Fischer 344 Rats Evaluated by Cell Magnetometry, Cytochemisry and Morphology

Objectives: The toxicity of microglass fibers (MG), one of the man-made mineral fibers, has not been sufficiently evaluated. The aim of the current study was to evaluate the cytotoxicity of MG in vitro. Methods: Alveolar macrophages were obtained from the bronchoalveolar lavage of male F344/N rats. The macrophages were exposed to MG at concentrations of 0, 40, 80, 160 and 320 μg/ml. The effects of MG on the macrophages were examined by cell magnetometry, LDH assay and morphological observation. Results: In the cell magnetometry experiment, a significant delay of relaxation (the reduction of remanent magnetic field strength) was observed in the cells treated with 160 and 320 μg/ml of MG in a dose-dependent manner. A significant increase in LDH release was also observed in the cells with 160 and 320 μg/ml in a dose-dependent manner. Changes in the cytoskeleton were observed after exposure to MG, by immunofluorescent microscopy using an α-tubulin antibody. Conclusions: The cytotoxicity of MG on alveolar macrophages was demonstrated with cell magnetometry. The mechanism of the toxic effects of MG was related to cytoskeleton damage.

Physicians' Awareness Regarding Evidence-based Medicine, Practice Guidelines and Clinical Information Resources in Japan / General Medicine

BACKGROUND: physicians' awareness regarding evidence-based medicine (EBM), clinical practice guidelines, and clinical information resources were rarely examined in Japan. We need to know them prior to the initiation of the Medical Information Network Distribution Service (Minds) by the Japan Council for Quality Health Care (JCQHC) .<BR>METHODS: A total of 10, 000 directors/owners of private clinics (CDs: clinic physicians) affiliated with the Japan Medical Association (JMA) and 8682 physicians working for hospitals certified by the JCQHC (HDs: hospital physicians) were randomly selected and surveyed by a mailed questionnaire.<BR>RESULTS: The response rate to the questionnaire was 18.7% (n=1865) among CDs and 67.8% (n=5885) among HDs. The percentage of respondents who uses internet was 39.9% among CDs and 69.3% among HDs. The information resource most commonly used by all respondents was medical journals, followed by textbooks. The percentage of respondents who used medical literature database was 10.8% among CDs and 49.7% among HDs, respectively. Approximately 80% of all respondents approved implementing EBM in daily practice. Fifty percent of all respondents indicated to have used clinical practice guidelines, and 90% of all the guideline users replied that clinical practice guidelines are useful tools for clinical decision-making. Over half of HDs required to access to the abstracts of the literature cited in the guidelines.<BR>CONCLUSIONS: Many physicians who responded to the survey acknowledged that EBM will contribute to improving the quality of medical services. They are positive in using clinical practice guidelines that include a series of recommendations proposed by specialists in the relevant field (s) in accordance to the reviewed evidence.

A Report on Internet-Based Epidemiology Distance Learning / 医学教育

Epidemiology has played a major role in improving global health in this century. Its importance has increased in the clinical field as well. However, systematic education in epidemiology is conducted only in public health schools in Western countries ; epidemiology is not taught at medical schools. The rapidly growing Internet is being used for distance learning. We took part as teaching assistants in an Internet-based distance learning course in epidemiology offered by the Department of Epidemiology, Graduate School of Public Health, University of Pittsburgh. This is the only Internet-based distance learning lecture on epidemiology that is free of charge. Four people in Japan took this course. In this report, we share our experiences with Internet-based distance learning in epidemiology.
