Reduced renal function is associated with prolonged hospitalization in frail older patients with non-severe pneumonia.

Objective: Pneumonia is a disease with high morbidity and mortality among older individuals in Japan. In practice, most older patients with pneumonia are not required ventilatory management and are not necessarily in critical respiratory condition. However, prolonged hospitalization itself is considered to be a serious problem even in these patients with non-critical pneumonia and have negative and critical consequences such as disuse syndrome in older patients. Therefore, it is essential to examine the factors involved in redundant hospital stays for older hospitalized patients with non-severe pneumonia, many of whom are discharged alive. Method: We examined hospitalized patients diagnosed with pneumonia who were 65 years and older in our facility between February 2017 and March 2020. A longer length of stay (LOS) was defined in cases in which exceeded the 80th percentile of the hospitalization period for all patients was exceeded, and all other cases with a shorter hospitalization were defined as a shorter LOS. In a multivariate logistic regression model, factors determining longer LOSs were analyzed using significant variables in univariate analysis and clinically relevant variables which could interfere with renal function, including fasting period, time to start rehabilitation, estimated glomerular filtration rate (eGFR), the Quick Sequential Organ Failure Assessment (qSOFA) score of 2 or higher, bed-ridden state. Results: We analyzed 104 eligible participants, and the median age was 86 (interquartile range, 82-91) years. Overall, 31 patients (30.7%) were bed-ridden, and 37 patients (35.6%) were nursing-home residents. Patients with a Clinical Frailty Scale score of 4 or higher, considered clinically frail, accounted for 93.2% of all patients. In multivariate analysis, for a decrease of 5 ml/min/1.73m2 in eGFR, the adjusted odds ratios for longer LOSs were 1.22 (95% confidence interval, 1.04-1.44) after adjusting for confounders. Conclusion: Reduced renal function at admission has a significant impact on prolonged hospital stay among older patients with non-severe pneumonia. Thoughtful consideration should be given to the frail older pneumonia patients with reduced renal function or with chronic kidney disease as a comorbidity at the time of hospitalization to prevent the progression of geriatric syndrome associated with prolonged hospitalization.

Behçet's Disease with Extremely High Levels of Urinary ß2-Microglobulin after Non-Steroidal Anti-Inflammatory Drug Treatment.

Behçet's disease is an inflammatory disease which manifests itself as various symptoms, such as uveitis, oral and genital aphthae, erythema nodosa, gastro-intestinal ulcerations and encephalopathy. Among the manifestations, renal dysfunction is reported in some percentage of the patients with this disorder. We experienced a middle-aged male with Behçet's disease who showed an extremely high level of urinary ß2-microglulin, which is one of the markers of renal dysfunction, despite normal serum creatinine levels. The patient was on non-steroidal anti-inflammatory drug (NSAID) therapy for 7 weeks, and this could have affected his renal dysfunction. The present report suggests that renal injury should not be underestimated in patients with Behçet's disease, especially in patients using NSAIDs.

Japanese Society for Cancer of the Colon and Rectum (JSCCR) guidelines 2016 for the treatment of colorectal cancer.

Japanese mortality due to colorectal cancer is on the rise, surpassing 49,000 in 2015. Many new treatment methods have been developed during recent decades. The Japanese Society for Cancer of the Colon and Rectum Guidelines 2016 for the treatment of colorectal cancer (JSCCR Guidelines 2016) were prepared to show standard treatment strategies for colorectal cancer, to eliminate disparities among institutions in terms of treatment, to eliminate unnecessary treatment and insufficient treatment, and to deepen mutual understanding between health-care professionals and patients by making these Guidelines available to the general public. These Guidelines were prepared by consensus reached by the JSCCR Guideline Committee, based on a careful review of the evidence retrieved by literature searches, and in view of the medical health insurance system and actual clinical practice settings in Japan. Therefore, these Guidelines can be used as a tool for treating colorectal cancer in actual clinical practice settings. More specifically, they can be used as a guide to obtaining informed consent from patients and choosing the method of treatment for each patient. As a result of the discussions held by the Guideline Committee, controversial issues were selected as Clinical Questions, and recommendations were made. Each recommendation is accompanied by a classification of the evidence and a classification of recommendation categories based on the consensus reached by the Guideline Committee members. Here we present the English version of the JSCCR Guidelines 2016.

Japanese Society for Cancer of the Colon and Rectum (JSCCR) Guidelines 2016 for the Clinical Practice of Hereditary Colorectal Cancer (Translated Version).

Hereditary colorectal cancer accounts for less than 5% of all colorectal cancer cases. Some of the unique characteristics that are commonly encountered in cases of hereditary colorectal cancer include early age at onset, synchronous/metachronous occurrence of the cancer, and association with multiple cancers in other organs, necessitating different management from sporadic colorectal cancer. While the diagnosis of familial adenomatous polyposis might be easy because usually 100 or more adenomas that develop in the colonic mucosa are in this condition, Lynch syndrome, which is the most commonly associated disease with hereditary colorectal cancer, is often missed in daily medical practice because of its relatively poorly defined clinical characteristics. In addition, the disease concept and diagnostic criteria for Lynch syndrome, which was once called hereditary non-polyposis colorectal cancer, have changed over time with continual research, thereby possibly creating confusion in clinical practice. Under these circumstances, the JSCCR Guideline Committee has developed the "JSCCR Guidelines 2016 for the Clinical Practice of Hereditary Colorectal Cancer (HCRC)," to allow delivery of appropriate medical care in daily practice to patients with familial adenomatous polyposis, Lynch syndrome, or other related diseases. The JSCCR Guidelines 2016 for HCRC were prepared by consensus reached among members of the JSCCR Guideline Committee, based on a careful review of the evidence retrieved from literature searches, and considering the medical health insurance system and actual clinical practice settings in Japan. Herein, we present the English version of the JSCCR Guidelines 2016 for HCRC.

[How Long Should We Continue the Chemotherapy?-From the View Point of Health Economics].

The continuation of cancer chemotherapy was examined from the view point of the patient's economic burden and the national finance. Along with the rapid technological progress, anti-cancer drugs become more and more expensive. According to our survey, not a little patient was obliged to give up the most appropriate treatment due to some economic reasons. The impact of the increasing cost of cancer treatment and the rational measure to minimize the patient's burden were discussed. The mean out-of-pocket expense of the patients without economic worries was three-fourths that of the patients with economic worries. In other words, if the economic burden is reduced by around a quarter in the patients whose burden is heavy, they would certainly receive optimal medical care. As for the situation in which the cancer chemotherapy have to be interrupted due to the constraint of limited funding, it seemed difficult to continue to avoid this thoroughly in the future without the drastic reform of medical insurance system. The importance to set priorities and allocate human and financial resources within the financial crunch was discussed while making reference to health care reforms of several western countries in the late 1990's.

Japanese Society for Cancer of the Colon and Rectum (JSCCR) Guidelines 2014 for treatment of colorectal cancer.

Colorectal cancer is a major cause of death in Japan, where it accounts for the largest number of deaths from malignant neoplasms among women and the third largest number among men. Many new methods of treatment have been developed during recent decades. The Japanese Society for Cancer of the Colon and Rectum Guidelines 2014 for treatment of colorectal cancer (JSCCR Guidelines 2014) have been prepared as standard treatment strategies for colorectal cancer, to eliminate treatment disparities among institutions, to eliminate unnecessary treatment and insufficient treatment, and to deepen mutual understanding among health-care professionals and patients by making these guidelines available to the general public. These guidelines have been prepared as a result of consensuses reached by the JSCCR Guideline Committee on the basis of careful review of evidence retrieved by literature searches and taking into consideration the medical health insurance system and actual clinical practice in Japan. They can, therefore, be used as a guide for treating colorectal cancer in clinical practice. More specifically, they can be used as a guide to obtaining informed consent from patients and choosing the method of treatment for each patient. As a result of the discussions of the Guideline Committee, controversial issues were selected as clinical questions, and recommendations were made. Each recommendation is accompanied by a classification of the evidence and a classification of recommendation categories, on the basis of consensus reached by Guideline Committee members. Here we present the English version of the JSCCR Guidelines 2014.

Proposal for the breakdown of increased cancer healthcare cost and its improvement.

Technological progress in the field of cancer treatment can be expected to accelerate in the future, giving hope to such patients. At the same time, there is concern that cancer care will become more expensive. It is indispensable to minimize the economic burden of patients to deliver technological advances in treatment. It is important for the physician engaged in cancer care to recognize the economic burden of patients and to reduce this burden as much as possible. The Cancer Control Act was enacted in 2007 to promote work on cancer control using all the resources of the nation, and this should surely entail financial support. In order to take advantage of innovations in cancer care, reform of the payment system to lighten the economic burden of the patient would be a pressing necessity.

Japanese Society for Cancer of the Colon and Rectum (JSCCR) guidelines 2010 for the treatment of colorectal cancer.

Colorectal cancer is a major cause of death in Japan, where it accounts for the largest number of deaths from malignant neoplasms in women and the third largest number in men. Many new treatment methods have been developed over the last few decades. The Japanese Society for Cancer of the Colon and Rectum (JSCCR) guidelines 2010 for the treatment of colorectal cancer (JSCCR Guidelines 2010) have been prepared to show standard treatment strategies for colorectal cancer, to eliminate disparities among institutions in terms of treatment, to eliminate unnecessary treatment and insufficient treatment, and to deepen mutual understanding between health-care professionals and patients by making these Guidelines available to the general public.

[Economic burden of cancer patients undergoing oral chemotherapy].

Due to constant medical advancement, the cost of cancer treatment has been spiraling and the economic burden of the patient has increased. In view of this, it is important to ease the patient's economic burden while pushing for high quality cancer treatment. We carried out a national level investigation with cancer patients and their medical doctors in charge and reviewed the policy to minimize the patients' burden.

The cost-effectiveness of risedronate treatment in Japanese women with osteoporosis.

We constructed a mathematical model for assessing the cost-effectiveness of providing BMD (bone mineral density) scans to Japanese women aged 55 years and over and treating, with risedronate, those that are shown to be osteoporotic. Fracture rates, cost data, utility values, and the increased risks of fractures associated with T-score and vertebral fracture history were taken from published literature. We estimated the cost of fractures avoided due to risedronate treatment, allowing the net changes in cost, incorporating both intervention and fracture costs to be calculated. The QALYs (quality adjusted life years) gained through treatment were calculated enabling cost per QALY ratios to be presented. Further analyses were undertaken assuming treatment was reserved for older women and/or those who had sustained a vertebral fracture in the previous 2 years. Cost per QALY values were inversely related to absolute risk of fracture. Assuming a cost per QALY value threshold of US dollars 100,000, we concluded that providing BMD scans to women aged 70 years and over who had sustained a vertebral fracture in the previous 2 years and treating those that were osteoporotic was cost-effective. However, providing BMD scans for women without a vertebral fracture in the previous 2 years was not cost-effective, even in women aged 85 years and older.

Strategies for improving pediatric services in Japan.

The shortage of pediatricians and emergency medical care for children is an issue of great concern in Japan. This study attempts to identify the problems in children's medical care and their causes. With multiple secondary data sources, we found that over 80% of outpatient pediatric services were provided by clinics, that over 95% of clinics were closed on holidays, Sunday, and Saturday night, that among the children's illnesses respiratory ailments were dominant and were generally acute and required immediate treatment or consultation, and that the revenue rates from providing services for children were lower than those for adults. That fewer clinics are open on Saturday night, Sunday and holidays, and workday evenings may be the main reason why it is difficult for children to find pediatric services outside of normal working hours. Lower revenue rates may be one of the key reasons why the number and rate of clinics and hospitals providing pediatric services continue to decline, and fewer physicians are willing to provide services for children. The findings in this research would provide important information of multiple dimensions for the governments to make efforts to improve pediatric services in Japan. Our proposition is to prompt pediatric specialists and internists who can treat pediatric cases in clinics to provide pediatric service systematically and alternatively at night, and to adjust the fee-for-service scales of pediatric services.

Impact of hormonal therapy prior to radical prostatectomy on the recovery of quality of life.

BACKGROUND: We investigated the changes in health-related quality of life (HRQOL) in patients who underwent prostatectomy (RP) with or without neoadjuvant hormonal therapy (NHT). METHODS: A total of 72 patients undergoing direct RP (DRP group) and 26 patients receiving neoadjuvant hormonal therapy (NHT group) were enrolled in the present study. The baseline interview was conducted before RP (not initiation of therapy). Follow-up interviews were conducted in person at scheduled study visits of 3, 6, and 12 months after surgery. We measured general and disease specific HRQOL with the Medical Outcomes Study 36-Item Short Form and University of California, Los Angeles Prostate Cancer Index, respectively. RESULTS: At baseline, the NHT group scored statistically lower for not only sexual function (P < 0.001), but also the general HRQOL, such as role limitations due to physical problems (P = 0.007), social function (P = 0.045) and mental health (P = 0.034), than the DRP group. The NHT group reported lower scores in social function and mental health at 3 months (P = 0.040 and 0.006, respectively). Patients who received NHT for more than 3 months continued to show significantly lower scores for some HRQOL domains 12 months later. CONCLUSION: Neoadjuvant hormonal therapy may decrease not only sexual function, but also general HRQOL before surgery. The recovery of HRQOL appeared to be further prolonged in patients who received long-term NHT.

Recovery of health related quality of life after radical prostatectomy in japanese men: a longitudinal study.

BACKGROUND: We performed a longitudinal survey of health related quality of life (HRQOL) after radical retropubic prostatectomy (RP) in Japanese men with localized prostate cancer. METHODS: The present study started with self-reported HRQOL assessments provided by 72 patients who received only RP. The RAND 36-Item Health Survey and the University of California, Los Angeles Prostate Cancer Index were administered before and 3, 6 and 12 months after RP. RESULTS: Patients who underwent RP showed problems in some domains of general HRQOL, but these problems diminished over time. Urinary function declined substantially at 3 months and continued to recover at 6 and 12 months, but scored lower than the baseline. Urinary bother at 3 months had a significant decrease, but at six months it turned out to be the same as the baseline. The data of sexual function and bother showed a substantially lower score after RP. The sexual bother score of the younger men was significantly worse than that of the older men. Those who underwent nerve sparing procedures experienced significantly better recovery of urinary and sexual functions than the non-nerve sparing group. CONCLUSION: Despite reports of problems with sexuality and urinary continence, general HRQOL was mostly unaffected by RP after 6 months. Although there was a substantial decrease in urinary function, recovery from urinary bother was rapid. Deterioration of the sexual domain was remarkable throughout the postoperative period. Therefore, careful attention should be given to preoperative counseling, especially for younger patients.

Health related quality of life in Japanese men after radical prostatectomy or radiation therapy for localized prostate cancer.

BACKGROUND: We performed a retrospective survey of general and disease specific health-related quality of life (HRQOL) after radical prostatectomy (RP) and external beam radiotherapy (XRT) in Japanese men. METHODS: A total of 186 patients underwent RP and 78 underwent XRT for clinically localized prostate cancer between 2000 and 2002. We measured the general and disease specific HRQOL with the MOS 36-Item Health Survey and the University of California, Los Angeles Prostate Cancer Index, respectively. Each treatment group was further divided into four subgroups according to the time scale. RESULTS: Patients from the RP group were significantly younger than those from the XRT group. The tumor characteristics differed significantly in their distributions among the treatment groups. Patients undergoing XRT had low scores in most of the general measures of HRQOL just after treatment, but after 6 months there were no differences between the treatment groups, except for the physical domains. The RP group was associated with worse urinary function, whereas the XRT group had worse bowel function and bother during the first 6 months after treatment. Thereafter, however, urinary and bowel domain did not differ between the groups. Both groups reported poor sexual function, although the RP group scored lower sexual bother. CONCLUSION: The patients who underwent RP had significantly worse urinary and better bowel function than those treated with XRT. Both treatment groups had decrements in sexual function throughout the post-treatment period; careful attention should be paid to this side-effect in preoperative counselling, especially in younger patients, regardless of the primary treatments.

[The perioperative charge equivalence of radical prostatectomy with 1-year follow up since the diagnosis of prostate cancer].

We assessed the 1-year charges in the group of patients undergoing radical prostatectomy and the changes in hospital costs and resource use following implementation of a clinical care path. A total of 69 consecutive men treated with radical prostatectomy for clinically localized prostate cancer were enrolled in the study. Hospital and outpatient records were analyzed for each patient in regard to preoperative, operative and postoperative charges of a 12-month period. Parameters included number of encounters, diagnostic and therapeutic interventions, hospitalization and operative charges, and follow-up visits, diagnostic tests and interventions for 1 year. The mean first-year cost of treatment with radical prostatectomy for localized prostate cancer was 144 x 10(4) yen. The increases in the first-year cost with higher prostate specific antigen (PSA) level for the diagnosis level appeared to primarily be associated with increased inpatient resource use and greater use of hormonal therapy. Length of the stay in a hospital significantly influenced the first-year cost. After implementation of the radical prostatectomy care path hospital costs decreased by 30% (66 x 10(4) yen vs 46 x 10(4) yen), total costs decreased 40% (190 x 10(4) yen vs 113 x 10(4) yen) and length of hospital stay decreased by 56% (37.0 vs 16.6). The first-year costs with radical prostatectomy are influenced greatly by the hormonal therapy and the number of hospital days. By standardizing preoperative and postoperative management for patients undergoing radical prostatectomy, significant savings can be achieved toward shorter hospital stays and lower hospital costs.

Health-related quality of life after radical prostatectomy in Japanese men with localized prostate cancer.

PURPOSE: We evaluated retrospectively health-related quality of life (HRQOL) after radical prostatectomy (RP) in Japanese men with localized prostate cancer. METHODS: The study was based on self-reported HRQOL of 280 patients. Patients were divided into seven groups: time 0 (T0), baseline before operation; T1, 1-3 months after RP; T2, 4-6 months after RP; T3, 7-12 months after RP; T4, 13-24 months after RP; T5, 25-36 months after RP; and T6, more than 36 months after RP. We measured the general and disease-specific HRQOL using the RAND 36-item Health Survey 1.0 (SF-36) and the University of California, Los Angeles Prostate Cancer Index (UCLA PCI). RESULTS: The general HRQOL of the postoperative groups was assessed by SF-36. The postoperative groups showed almost the same or higher scores than those of the baseline group. Urinary function scores decreased substantially after surgery. In contrast, there was no difference in urinary bother between the baseline and postoperative groups. Sexual function deteriorated substantially in all postoperative groups. Similarly, the sexual bother score significantly deteriorated after RP. The sexual bother score of men aged 65-years or younger was significantly worse than that of their counterparts in the T1-2 groups. CONCLUSION: Despite reports of problems with sexual activity and urinary continence, general HRQOL was mostly unaffected by RP. Although there was a substantial decrease in urinary function, recovery from urinary bother was rapid. Since the deterioration of sexual function was marked through the postoperative period, careful attention should be paid to this issue during preoperative counseling, especially for younger patients.

[Economic analysis of adverse events in cancer treatment].

Faced with limited resources and the desire to improve the quality of cancer care, there is an increasing interest among physicians in maximizing gains in cancer treatment. This paper discusses where to find cost-benefit estimates for a host of adverse events in cancer treatments. In order to clarify the relationship between the input resources and economic effects of supportive therapies against adverse events, we developed a system model, similar to the Marcov model, of prognosis of principal seven cancers and analyzed the balance of patient labor productivity (Benefit) and accumulated cancer care costs (Cost). Economic analysis is a useful guide to resource allocation and appropriate decision making for improving patient's QOL.
