DPC is the diagnosis dominant classification defined by diagnosis and procedures. The comprehensive daily payment system by DPC is being implemented in 731 hospitals across Japan. Of the hospitals affiliated with the Japanese Federation of Agricultural Cooperatives for Health and Welfare, 24 hospitals introduced this system in 2008. In September 2008 we mailed a questionnaire to them, and 23 hospitals responded. The mean of the comprehensive pay amounted to 105% of the piece rate. The average length of hospital stay shortened from 15.7 to 14.2 days. The bed occupancy rate decreased from 86.5 to 81.4%. For the preservation of the bed usage, most of the respondents said it was essential to keep in contact with neighboring hospitals and clinics. The adaptation rate of clinical pathways was only 29%. The proportion of generic drugs was 5.9%. In the DPC payment system it is necessary to maintain both the quality of medicine and the cost-effectiveness.

The comprehensive daily payment system by DPC developed the standardization of medical care and cost-effectiveness. We can exchange intelligence of other hospitals through the benchmark. Clinical pathways were useful for both the standardization and cost-benefit analysis. The production of pathways improved the communication between hospital employees. The excessive shortening of the average length of hospital stay decreased the rate of bed usage. The DPC payment system leaves much room for improvement in the quality of medical treatment and care.

Objectives: The staging system of the International Union Against Cancer considers tumor deposits to be N1c in patients with no regional lymph node metastasis, but the significance of tumor deposits in patients with regional lymph node metastases is unclear. We investigated the effect of tumor deposits on overall survival in colorectal cancer patients with regional lymph node metastases.
Patients and Methods: From 2000 to 2008, 551 patients underwent resections for colorectal cancer at our medical center. We excluded 87 patients who had distant metastases or had received neoadjuvant chemotherapy or radiotherapy from our study andstatistically analyzed the remaining 464 patients.
Results: Stepwise multivariate Cox proportional hazards analysis in patients with regional lymph node metastases showed only tumor deposits to be significant for overall survival (hazard ratio: 2.813; P = 0.0002). Recurrence was seen in 49.2% of patients with tumor deposits (30/61) compared with 14.4% of patients without them (58/403; P < 0.0001). Tumor deposits did not show the same effect on overall survival as lymph node metastases.
Conclusions: Tumor deposits were significantly associated with poorer overall survival in colorectal cancer patients with regional lymph node metastases. The effect of tumor deposits on overall survival was between that of lymph node metastasis and distant metastasis.

There is a theory that excessive treament for terminally ill patients is one of the factors in soaring medical costs. To evaluate this theory, we examined the changes in medical expenditures for our inpatients: 41 patients with lung cancer and 69 patients with liver cancer hospitalized for treatment of the department of internal medicine, and 90 patients with stomach cancer and 100 patients with colon cancer hospitalized for surgery from July to December 1997. They were divided to two groups: the patients of group A received active treatment, and the patients of group B received conservative treatment. We selected 10 people randomly from each group, and compared the changes in medical costs.
The cost was significantly low in group B compared with group A. We examined the change in the cost every 5 days. Until 6 days before leaving our hospital, the cost is high sugnificantly in group A compared with group B. The difference between group A and group B in the cost of treatment for lung cancer, and stomach cancer patients disappeared in 5 days before leaving hospital. The cost of treatment for lung and liver cancer patients of group A was a little higher than the average hospitalization fee of internal medicine. Also, the cost of group A stomach cancer patients was a little higher than the averge hospitalization fee of surgery, though there was no difference between the cost of treatment for group A colon cancer patients and the average hospitalization feeof surgery. The fee of group B of either disease was half or less of an average fee for medical treatment.
From this study, no evidence was found that the excessive life prolongation treatment for terminally ill patients was done. So, using authentic data, we should discuss the justifiability of the theory that the excessive treatment for terminally ill patients is one of the factors contributing to a boost in medical costs.

  Recently, the relevance of Helicobacter pyroli (H. pylori) infection to atrophic gastritis and gastric cancer in has been elucidated. Therefore, to diagnose H. pylori infection is important for suspecting the existence of those diseases of the stomach. We investigated the relationships of the H. pylori IgG antibody to H. pylori infection, atrophic gastritisor various stomach lesions to understand the significance and usefulness of evaluating the antibody level in the annual multiphasic health check-up participants. The subjects in this study were 148 people (male: 93, female: 55, average age: 56.4) in Toride city, which is located in the suburb of Tokyo. They had visited our hospital for medical checkups. Eighty-seven subjects underwent upper gastric endoscopy and 55 (63%) tested positive for H. pylori IgG antibody and H. pylori infection was confirmed in 41 (75%). Although 32 subjects tested negative for the antibody, 8 cases (25%) was diagnosed with H. pylori infection. The frequencies of positive antibody in atrophic gastritis, erosion and ulcer, fundic gland polyp, hyperplastic foveolar polyp, adenoma and malignancy were 17%, 70%, 61%, 77%, 31%, 62%, 0% and 100%, respectively. On the other hand of 80 subjects were who underwent barium X-ray examination, 44 tested positive for the antibody (55%). The frequency of positive antibody in no lesion, depressed lesion, elevated lesion and malignant lesion were 61%, 59%, 36% and 100%, respectively. Taken together, H. pylori antibody was a good marker for H. pylori infection and the positive antibody indicated high frequencies of atrophic gastritis and malignancy. Therefore, advices to have participants who have a positive antibody should be strongly an endscopic examination stomach lesions.

  In our hospital the palliative care committee has been held once a month since 2000. In 2007, a total of 1,583 cancer patients were admitted to our hospital orreceived medical care at home. The average length of hospital stay was 24 days. Of the total number of patients, 88.4% was informed that they had cancer. In the latter half of the year it increased to 92.6% because the palliative caretakers gave doctors accurate information on patients' psychology and social background. In October 2007 a questionnaire survey was conducted on those who visited our palliative care section on the occasion of the hospital festival. A total of 46 responded to our survey about the knowledge of palliative care, physician's precise explanation about the illness, image of opioids, desirable place of death and so on. Twenty-eight respondents (60.9%) did not know anything about palliative care. Forty-four (95.7%) wanted precise explanation of cancer. Thirty-four (73.9%) said they had had a night image of opioids after reading the panel. Twenty-eight (60.9%) responded they would rather stay at home until death. We should give healthy people more information about palliative care and opioids.

Background: Blood culture is an essential examination for diagnosis of causative microorganisms and determination of optimal antimicrobials in serious cases of infectious diseases. We examined temporal trends in the number and multiplicities of blood culture submission, two pre-analytic parameters indicating quality of the examination, in the Minami Ibaraki Area.
Methods: We reviewed all computerized and available paper-based laboratory records of microbiological examination in five hospitals in the area between 2002 and 2011.
Results: Blood culture submissions, estimated to be 2.4–7.3 (median: 5.1) sets per hospital bed, 8.6–23 (17) per 1,000 inpatient-days, and 0.13–0.41 (0.25) per newly admission in 2011, almost constantly increased during the study period in all hospitals. Proportions of blood specimens to all materials for microbiological cultures also increased up to 15–30% (20%) in 2011. In contrast, it was not until the latter half of the study period that solitary submission, accounting for 26–56% (35%) in 2011, decreased. Positive blood cultures were between 11 and 28% through the study period. Coagulase-negative staphylococci accounted for approximately one fourth of recovered organisms in 2006 and 2011.
Conclusion: Frequency and multiplicity of blood culture submission markedly increased in hospitals in the Minami-Ibaraki Area of Japan.
