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) .
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.
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.
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.

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.
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.
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’.
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.

Objective: The need for tailoring ovarian cancer treatments to individual patients is increasing. This study aimed to evaluate the prognostic value of pretreatment laboratory test data for predicting the response and survival outcomes of platinumbased chemotherapy in ovarian cancer. Methods: We enrolled 270 patients with ovarian cancer diagnosed at the Kyoto Medical Center (n=120; group A) and Kyoto University (n=150; group B). Data on 9 blood parameters (neutrophil to lymphocyte ratio [NLR], platelet to lymphocyte rate [PLR], C-reactive protein, lactate dehydrogenase [LDH], glucose, total cholesterol, high-density lipoprotein [HDL], low-density lipoprotein, and triglyceride levels), cancer pathology, cancer stage, cytoreduction outcomes, serum cancer antigen 125 levels, platinum-free interval (PFI), disease-free survival (DFS), and overall survival were assessed retrospectively. Results: NLR, PLR, LDH, and HDL were significantly different in advanced stage patients (P<0.001, <0.001, 0.029, and <0.001, respectively). The Kaplan-Meier curves revealed that high LDH level (≥250 U/L) was associated with reduced PFI (P=0.037 and 0.012) and DFS (P=0.007 and 0.002) in groups A and B, respectively. High NLR (≥4) was associated with reduced DFS in both groups (P=0.036 and 0.005, respectively). LDH showed higher area under the curve (AUC) values in predicting platinum resistance with a PFI of less than 6 months and 12 months (AUC=0.606 and 0.646, respectively) than NLR. In the multivariate analysis, LDH remained significant (P=0.019) after adjusting for the 9 blood parameters. Conclusion Serum LDH level may possibly predict platinum resistance and prognosis in ovarian cancer and may be useful when developing precision medicine for individual patients.

A questionnaire was administered to identify differences between the information that ward nurses think should be provided on a discharge summary and the information that outpatient nurses consider is necessary for providing continuing nursing care. Respondents were asked to select from multiple choice answers which information they believe is necessary to provide on a discharge summary and their perceptions about continuing nursing care, and they were also asked to record the reasons for their selections. Multiple choice responses were aggregated by simple tabulation and reasons were aggregated by similarity. The results showed that ward nurses and outpatient nurses had the same perceptions of what information is needed on a discharge summary. However, whereas the outpatient nurses wanted to see specific information about what care should be continued on the discharge summary, the ward nurses considered continuing nursing care to mean sharing summarized information about the patient's hospital course. This difference can be attributed to the unique characteristics of ward nurses and outpatient nurses. To provide continuing nursing care, ward nurses and outpatient nurses should each understand the other's thinking and learn what information the other considers necessary.
