RESUMO
AIM: To describe factors affecting critical appraisal of research articles in evidence-based practice by certified nurse specialists who were advanced practice nurses in Japan. DESIGN: A descriptive qualitative study. METHODS: Fourteen certified nurse specialists with master's degree were included by a snowball sampling to maximize the variety of specialty fields for advanced practice nurses in Japan. Individual semi-structured interviews were conducted between November 2016 and March 2017. Interview guides included the experience of evidence-based practice and learning about critical appraisal. RESULTS: The following four aspects were identified as factors affecting the critical appraisal of research articles in evidence-based practices-individual beliefs and attitude, learning status, organizational readiness and availability of research evidence. Each factor included both positive and negative aspects for critical appraisal in evidence-based practice. PATIENT OR PUBLIC CONTRIBUTION: If advanced practice nurses acquire knowledge/skills of critical appraisal, they would be able to select more appropriate care. This will increase to improve the health-related outcome for patients or populations.

AIMS: This work aims to map instruments available in Japanese that have been assessed for reliability or validity for measuring evidence-based practice (EBP) among clinical nurses. BACKGROUND: As EBP competencies comprise various domains, many EBP instruments have been developed. However, instruments available in Japanese for measuring EBP have not been reported systematically. DESIGN: We conducted a scoping review. DATA SOURCES: Two different bibliography databases were searched to identify EBP instruments published until 2019: ICHUSHI (for Japanese articles) and PubMed. REVIEW METHODS: After relevant studies were screened and identified, study profile characteristics were extracted to identify EBP instruments in Japanese, and the quality of methodology for developing such instruments was evaluated. This information was recorded and the characteristics were descriptively summarized. RESULTS: Ninety potentially relevant articles were identified, of which seven articles and nine instruments were included in this review. All instruments were based on self-reported self-efficacy and attitudes. Few Japanese instruments included all the steps required for EBP. The overall reporting quality of each instrument was low. CONCLUSIONS: EBP instruments available in Japanese are extremely scarce. The study results show that it is difficult to measure the various aspects of EBP with the existing instruments.

AIM: To explore the individual factors (such as gender, division of household labor, childcare and elder care) and their impact on research activities in the Japanese nursing research community during the early stage of the COVID-19 pandemic from April to June in 2020. DESIGN: Cross-sectional study. METHODS: An online survey with a self-reported questionnaire was conducted on Japan Academy of Nursing Science members to explore the impacts of individual factors among Japanese nursing researchers from April to June 2020. A multivariate logistic regression model was used for data analysis. RESULTS: A total of 1,273 participants (90.7% female, 85.8% university faculty) were included in the analysis. This survey showed that no evidence of a significant gender gap was found in research activities in Japanese nursing researchers during the COVID-19 pandemic. Research activities during the pandemic were associated with time and motivation.

The Omaha System is a popular and standard term used in community health. This scoping review aimed to update the research types and identify new usage trends for the Omaha System through articles published between 2012 and 2019. The bibliography databases PubMed, CINAHL, Scopus, PsycInfo, Ovid, and ICHUSHI and the Omaha System's Web site were used to search for publications. Research articles published between 2012 and 2019 that included "Omaha System" in the title or abstract and were written in English or Japanese were included in this review. After excluding duplicate articles, 305 articles were screened and 82 were included in our analysis. There was a median of 10.3 articles per year. The percentages for each type of use of the Omaha System to "analyze client problem," "analyze clinical process," "analyze client outcomes," and "advanced classification research" were 18.3%, 12.2%, 23.2%, and 4.9%, respectively. The reclassification of the type "others" (41.5%) included "use the Omaha System data for assessment for other than clients," "use the Omaha System data as structured data," "encode by the Omaha System code," "adopt the OS framework," "clinical information system," and "literature review." This newly reclassified category will help capture future research trends using the Omaha System.

AIMS/INTRODUCTION: We aimed to evaluate the metabolic status of pregnant women by assessing metabolic biomarkers of participants in the Japan Environment and Children's Study, a nationwide, multicenter, pregnancy and birth cohort. MATERIALS AND METHODS: Pregnant women aged 14-50 years were studied in 15 centers across Japan. Clinical information was obtained using self-administered questionnaires. Blood samples were taken during the first two trimesters to measure metabolic biomarkers. Samples were divided into seven groups according to the weeks of pregnancy. RESULTS: Among 82,972 pregnant women, 43 had only type 1 diabetes, 78 had only type 2 diabetes, 2,315 had only gestational diabetes and 354 had only dyslipidemia. Glycated hemoglobin, total cholesterol, low-density lipoprotein cholesterol and triglyceride across all the percentiles increased as prepregnancy body mass index increased, whereas high-density lipoprotein cholesterol levels across all the percentiles decreased as body mass index increased. Glycated hemoglobin was high in participants with type 1 diabetes or type 2 diabetes only, but not in those with gestational diabetes or hyperlipidemia only. Participants with type 2 diabetes or dyslipidemia only had high triglyceride in the first trimester, which then decreased in the second trimester. Participants with type 2 diabetes only also showed low high-density lipoprotein cholesterol, whereas participants with dyslipidemia only showed high total cholesterol and low-density lipoprotein cholesterol throughout. CONCLUSIONS: Metabolic biomarkers were affected by blood sample timing and underlying metabolic disease. The Japan Environment and Children's Study will clarify the influences of metabolic status during pregnancy on the health and development of the offspring in future studies.

AIM: This study aimed to explore sociodemographic factors related to evidence-based practice (EBP) competency in Japanese nurses in university hospitals. METHODS: In March 2016, a survey was distributed to 843 clinical nurses who directly provide nursing care at two university hospitals in Japan. Multiple regression analyses were conducted on data received from 472 nurses using the Evidence-Based Practice Questionnaire (Japanese version). RESULTS: Sociodemographic factors related to EBP competency were experience with conducting nursing research as a part of continuing education, education about EBP, advanced practice certification (certified nurse specialists/certified nurses), and years of experience in clinical nursing. These factors differed across the four subscales of the questionnaire: Practice, Attitude, Knowledge of Research and Practice, and Skills of Research and Practice. Specifically, experience with two or more nursing research activities was significantly positively associated with Attitude and Knowledge/Skills Concerning Research and Practice of EBP, but not related to the implementation of EBP itself. Advanced practice certification was significantly positively associated with Practice and Attitude of EBP. CONCLUSIONS: Our study quantitatively identified sociodemographic factors including experience with conducting nursing research and advanced practice certification status that were found to be related to EBP competency and these factors were differently associated with the four subscales of the Evidence-Based Practice Questionnaire (Japanese version). EBP education should depend on nurses' levels of EBP competency, and nursing educators and managers need to be cognizant of their nurses' sociodemographic factors when providing EBP education.

BACKGROUND: The aims of the present report were to estimate the prevalence of congenital anomalies (CAs) among infants in Japan using data from the Japan Environment and Children's Study (JECS) and to evaluate the validity of CA classification within JECS. METHODS: Data on CAs were collected at delivery and at age 1 month from the medical records of 101,825 infants at 15 regional centers. The analyses focused on 61 CAs, selected on the basis of reported associations with environmental exposure. Prevalence per 10,000 pregnancies (including miscarriages, stillbirths, and live births) was stratified according to four reporting patterns (at delivery, at age 1 month, at either, and at both). To evaluate the accuracy of observed CA prevalence, the medical records of 179 cases from a single JECS regional center underwent independent, retrospective re-evaluation. RESULTS: The prevalence of major CAs in four reporting patterns (at delivery, at age 1 month, at either, and at both) was 2.4, 2.6, 3.5, and 1.4 for myelomeningocele/spina bifida; 4.3, 4.2, 5.3, and 3.2 for cleft palate; 18.1, 17.4, 19.5, and 15.1 for cleft lip with or without cleft palate; 73.4, 100.3, 120.8, and 52.8 for congenital heart disease; and 10.5, 14.1, 15.0, and 9.6 for Down's syndrome, respectively. In the subsample re-evaluation, CA diagnoses were confirmed for 92.7%, 93.3%, 90.5%, and 97.8% of cases in the four reporting patterns (at delivery, at age 1 month, at either, and at both), respectively. CONCLUSIONS: The present report generated reliable data concerning the prevalence of major CAs in JECS.

PURPOSE: The aim of this study was to examine the quality of data from the National Clinical Database (NCD) via a comparison with regional government report data and medical charts. METHODS: A total of 1,165,790 surgical cases from 3007 hospitals were registered in the NCD in 2011. To evaluate the NCD's data coverage, we retrieved regional government report data for specified lung and esophageal surgeries and compared the number with registered cases in the NCD for corresponding procedures. We also randomly selected 21 sites for on-site data verification of eight demographic and surgical data components to assess the accuracy of data entry. RESULTS: The numbers of patients registered in the NCD and regional government report were 46,143 and 48,716, respectively, for lung surgeries and 7494 and 8399, respectively, for esophageal surgeries, leading to estimated coverages of 94.7% for lung surgeries and 89.2% for esophageal surgeries. According to on-site verification of 609 cases at 18 sites, the overall agreement between the NCD data components and medical charts was 97.8%. CONCLUSION: Approximately, 90-95% of the specified lung surgeries and esophageal surgeries performed in Japan were registered in the NCD in 2011. The NCD data were accurate relative to medical charts.

BACKGROUND: Japan Congenital Cardiovascluar Surgical Database (JCCVSD) is a nationwide registry whose data are used for health quality assessment and clinical research in Japan. We evaluated the completeness of case registration and the accuracy of recorded data components including postprocedural mortality and complications in the database via on-site data adjudication. METHODS: We validated the records from JCCVSD 2010 to 2012 containing congenital cardiovascular surgery data performed in 111 facilities throughout Japan. We randomly chose nine facilities for site visit by the auditor team and conducted on-site data adjudication. We assessed whether the records in JCCVSD matched the data in the source materials. RESULTS: We identified 1,928 cases of eligible surgeries performed at the facilities, of which 1,910 were registered (99.1% completeness), with 6 cases of duplication and 1 inappropriate case registration. Data components including gender, age, and surgery time (hours) were highly accurate with 98% to 100% concordance. Mortality at discharge and at 30 and 90 postoperative days was 100% accurate. Among the five complications studied, reoperation was the most frequently observed, with 16 and 21 cases recorded in the database and source materials, respectively, having a sensitivity of 0.67 and a specificity of 0.99. CONCLUSIONS: Validation of JCCVSD database showed high registration completeness and high accuracy especially in the categorical data components. Adjudicated mortality was 100% accurate. While limited in numbers, the recorded cases of postoperative complications all had high specificities but had lower sensitivity (0.67-1.00). Continued activities for data quality improvement and assessment are necessary for optimizing the utility of these registries.

AIM: To develop and test the validity and reliability of a Japanese version of the Evidence-Based Practice Questionnaire. METHODS: The Evidence-Based Practice Questionnaire was translated into Japanese, and a back-translation was performed. In March 2016, the survey was conducted among 843 nurses in 2 university hospitals in Japan. After 2 weeks, the same questionnaire for test-retest reliability was distributed to 197 nurses. We evaluated construct validity by factor analysis: convergent, discriminant, criterion-based and known-group validity, and reliability (internal consistency via Cronbach' alpha and test-retest reliability). RESULTS: A total of 533 (66%) of nurses who agreed to our study returned the completed questionnaire, and 108 nurses (55%) agreed to the test-retest. Factor analysis confirmed that the original model of the Evidence-Based Practices Questionnaire was not statistically appropriate for Japanese nurses. Therefore, the final version of the Japanese version adopted 18 items and 4 subscales including practice, attitudes, and knowledge/skills related to research and practice. In the final version, the validity and reliability were moderate (Cronbach alpha = .90). CONCLUSION: The Japanese version of the Evidence-Based Practices Questionnaire is a reliable and valid tool and can be used to assess evidence-based practice, attitudes, and research knowledge/skills in Japan.

We investigated the effect of using a fall risk screening tool in an electronic medical record system by using data for 25 039 patients in 24 general wards of a single institution. The probability of the occurrence of falls decreased after the tool was implemented, but using the tool did not reduce the actual occurrence of falls. This indicates that we must improve not only the assessment of the risk of falls but also the interventions to prevent falls.

BACKGROUND: Total gastrectomy is a relatively difficult and invasive procedure among gastrointestinal surgeries, and major morbidities following total gastrectomy can be serious and fatal. This study aimed to develop and validate preoperative risk models of morbidities associated with total gastrectomy using a Japanese web-based nationwide registry. METHODS: The national clinical database was used to retrieve the records of 39,253 patients who underwent total gastrectomy in 1,841 hospitals between January 1, 2011 and December 31, 2012. RESULTS: Mean patient age was 69.1 years, and 73.8% of the patients were male. The overall morbidity rate was 21.5%, which included 8.1% with surgical site infection (SSI), 4.5% with anastomotic leak, 5.0% with pancreatic fistula, 3.7% with pneumonia, 1.9% with prolonged ventilation, and 1.2% with renal failure. Sex, splenectomy, and Brinkman index were selected as common risk factors for SSI, anastomotic leak, and pancreatic fistula. Pancreatectomy was the most significant preoperative risk factor in the risk model of SSI and pancreatic fistula. Need of assistance with activities of daily living, chronic obstructive pulmonary disease, previous cerebrovascular disease, American Society of Anesthesiologists score class 3 and over, presence of esophageal cancer, and body mass index more than 25 were selected as common risk factors for pneumonia, prolonged ventilation over 48 h, and renal failure. CONCLUSIONS: We have created the first reported risk models of morbidities associated with total gastrectomy, using a Japanese nationwide database. The risk models developed in this study may be useful to preoperatively predict operative morbidities in patients undergoing total gastrectomy.

PURPOSE: The aim of this study was to investigate whether young age at onset of breast cancer is an independent prognostic factor in patients from the Japanese Breast Cancer Registry, after adjustment of known clinicopathological prognostic factors. METHODS: Of the 53,670 patients registered between 2004 and 2006 and surveyed after a 5-year follow-up prognosis, 25,898 breast cancer patients (48.3 %), who were obtained prognostic data, were examined. Clinicopathological factors were compared between young adult (YA; <35 years), middle-aged adult (MA; 35-50 years), and older adult (OA; >50 years) patients. Five-year disease-free survival (DFS) and overall survival (OS) rates were studied. RESULTS: YA patients were associated with an advanced TNM stage and aggressive characteristics (e.g. human epidermal growth factor receptor 2 (HER2)-positive or oestrogen receptor (ER)-negative breast cancers) compared to MA and OA patients (P < 0.001). The 5-year DFS and OS rates were 79.4 % and 90.8, 88.5 and 95.0 %, and 87.8 % and 91.6 % for YA, MA, and OA patients, respectively. From the multivariable regression analysis, young age at onset was confirmed as an independent prognostic factor for both DFS (hazard ratio 1.73, 95 % confidence interval 1.42-2.10; P < 0.001) and OS (hazard ratio 1.58, 95 % confidence interval 1.16-2.15; P = 0.004). CONCLUSIONS: Young age at onset is an independent negative prognostic factor in breast cancer. Further studies are required to develop new therapeutic strategies for YA breast cancer patients.

To support nursing care for the prevention of falls among inpatients at our institution, we developed and implemented a fall risk prediction tool. To evaluate its effectiveness, we compared the number of falls among inpatients before and after its implementation. The odds ratio for the probability of falling was 0.79 (95% confidence interval: 0.69-0.91) (p < 0.001), which was adjusted based on institutional data comprising 573,216 records from 25,039 patients in 24 general wards. Although whether nurses used the tool completely or whether the dissemination of fall prevention measures led to behavioral changes among the nurses in relation to their care remained unclear, the fall risk of inpatients appeared to be reduced after implementation of the prediction tool.

The rate of breast cancer screening for women of all ages in Japan is increasing. However, little is known about the biological differences between screen- and self-detected tumors. We used data from the Japanese Breast Cancer Registry (JBCR), a nationwide registry of newly diagnosed breast cancer cases in Japan, to investigate patients diagnosed between January 1, 2004 and December 31, 2011. We compared the clinicopathological features of tumors and assessed yearly trends regarding the proportion of screen-detected cases during the study period. We found that 31.8 % (65,358/205,544) of cancers were detected by screening. Asymptomatic tumors detected by screening (asymptomatic) were more likely to have favorable prognostic features than those that were self-detected (ductal carcinoma in situ [DCIS]: 19.8 versus 4.1 %, node-negative: 77.0 versus 61.6 %, and estrogen receptor-positive [ER+]: 82.0 versus 72.9 %, respectively). All these findings were statistically significant (p < .001). The proportion of breast cancers detected by screening among all cases increased from 21.7 % in 2004 to 37.1 % in 2011. During the same time period, the proportion of screen-detected DCIS increased from 41.5 to 66.0 % and that of ER+ cancers increased from 23.2 to 39.7 %. This study demonstrated that low-risk tumors, including DCIS, ER+, and lower TNM stage, account for a substantial proportion of clinical screening-detected cancers. The differences in biological characteristics between screen- and self-detected cancers may account in part for the limited efficacy of breast cancer screening programs aimed at improving breast cancer mortality.

Few studies have reported the association between body mass index (BMI) and outcome among Asian breast cancer patients. We analyzed data for 20,090 female invasive breast cancer patients who had been followed-up for a median period of 6.7 years entered in the National Clinical Database-Breast Cancer Registry between 2004 and 2006. We used mainly the WHO criteria for BMI (kg/m(2) ) categories; <18.5 (underweight), ≥18.5-<21.8 (reference), ≥21.8-<25, ≥25-<30 (overweight), and ≥30 (obese). We divided normal weight patients into two subgroups because this category includes many patients compared to others. The timing of BMI measurement was not specified. The Cox proportional hazards model and cubic spline regression were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). Smoking, alcohol, and physical activity were not controlled. A total of 1418 all-cause, 937 breast cancer-specific deaths, and 2433 recurrences were observed. Obesity was associated with an increased risk of all-cause (HR: 1.46; 95% CI: 1.16-1.83) and breast cancer-specific death (HR: 1.47; 95% CI: 1.11-1.93) for all patients, and with all-cause (HR: 1.47; 95% CI: 1.13-1.92) and breast cancer-specific death (HR: 1.58; 95% CI: 1.13-2.20) for postmenopausal patients. Being underweight was associated with an increased risk of all-cause death for all (HR: 1.41; 95% CI: 1.16-1.71) and for postmenopausal patients (HR: 1.45; 95% CI: 1.15-1.84). With regard to subtype and menopausal status, obesity was associated with an increased risk of breast cancer-specific death for all cases of luminal B tumor (HR: 2.59; 95% CI: 1.51-4.43; Pheterogeneity of Luminal B vs. Triple negative = 0.016) and for postmenopausal patients with luminal B tumor (HR: 3.24; 95% CI: 1.71-6.17). Being obese or underweight is associated with a higher risk of death among female breast cancer patients in Japan.

The aim of the study was to evaluate preoperative variables predictive of lethal morbidities in critically ill surgical patients at a national level.There is no report of risk stratification for morbidities associated with mortality in critically ill patients with acute diffuse peritonitis (ADP).We examined data from 16,930 patients operated during 2011 and 2012 in 1546 different hospitals for ADP identified in the National Clinical Database of Japan. We analyzed morbidities significantly associated with operative mortality. Based on 80% of the population, we calculated independent predictors for these morbidities. The risk factors were validated using the remaining 20%.The operative mortality was 14.1%. Morbidity of any grade occurred in 40.2% of patients. Morbidities correlated with mortality, including septic shock, progressive renal insufficiency, prolonged ventilation >48 hours, systemic sepsis, central nervous system (CNS) morbidities, acute renal failure and pneumonia, and surgical site infection (SSI), were selected for risk models. A total of 18 to 29 preoperative variables were selected per morbidity and yielded excellent C-indices for each (septic shock: 0.851; progressive renal insufficiency: 0.878; prolonged ventilation >48 h: 0.849; systemic sepsis: 0.839; CNS morbidities: 0.848; acute renal failure: 0.868; pneumonia: 0.830; and SSI: 0.688).We report the first risk stratification study on lethal morbidities in critically ill patients with ADP using a nationwide surgical database. These risk models will contribute to patient counseling and help predict which patients require more aggressive surgical and novel pharmacological interventions.

BACKGROUND: The Japan Cardiovascular Surgery Database (JCVSD) is a nationwide benchmarking project to improve the quality of cardiovascular surgery in Japan. This study aimed to develop new JACVD risk models not only for operative mortality but also for each postoperative complication for coronary artery bypass grafting (CABG) operations, valve operations, and thoracic aortic operations. METHODS: We analyzed 24,704 isolated CABG operations, 26,137 valve operations, and 18,228 thoracic aortic operations. Risk models were developed for each operation for operative death, permanent stroke, renal failure, prolonged ventilation (>24 hours), deep sternal wound infection, and reoperation for bleeding. The population was divided into an 80% development sample and a 20% validation sample. The statistical model was constructed by multiple logistic regression analysis. Model discrimination was tested using the area under the receiver operating characteristic curve (C index). RESULTS: The 30-day mortality rates for isolated CABG, valve, and thoracic aortic operations were 1.5%, 2.5%, and 6.0%, respectively, and operative mortality rates were 2.4%, 3.8%, and 8.4%, respectively. The C indices for the end points of isolated CABG, valve, and aortic thoracic operations were 0.6358 for (deep sternal infection) to 0.8655 (operative mortality), 0.6114 (reoperation for bleeding) to 0.8319 (operative death), and 0.6311 (gastrointestinal complication) to 0.7591 (operative death), respectively. CONCLUSIONS: These risk models increased the discriminatory power of former models. Thus, our models can be said to reflect the current state of Japan. With respect to major complications, useful feedback can now be provided through the Japan Cardiovascular Surgery Database Web-based system.

OBJECTIVE: The purpose of this study was to develop risk models for congenital heart surgery short-term and midterm outcomes from a nationwide integrated database drawn from hospitals in Japan. METHODS: The Japan Congenital Cardiovascular Surgery Database collects clinical information from institutions throughout Japan specializing in congenital heart surgery. Variables and definitions used in the Japan Congenital Cardiovascular Surgery Database are almost identical to those of the Society of Thoracic Surgeons-European Association for Cardiothoracic Surgery database for congenital heart surgery. We used logistic regression to develop risk models, which were then validated through spilt-sample validation. In addition to procedural complexity categories by Risk Adjustment in Congenital Heart Surgery (RACHS-1) score, we incorporated patient characteristics to predict surgical outcome. RESULTS: Among 8923 congenital heart operations performed at 69 sites with cardiac surgical programs, 30-day mortalities by RACHS-1 category were as follows: I, 0.1% (n=1319); II, 0.5% (n=3211); III, 2.2% (n=3285); IV, 4.3% (n=818); and V and VI, 8.6% (n=290). From the test data set (n=7223), we developed 3 risk models (30-day mortality, 90-day mortality, and 90-day and in-hospital mortality) with 11 variables, including age category, RACHS-1 category, preoperative risk factors, number of surgical procedures, unplanned reoperations, status of surgery, surgery type, asplenia, and prematurity (<35 weeks). For the performance metrics of the risk models, C statistic values of 30-day, 90-day, and 90-day and in-hospital mortalities for the test data set were 0.85, 0.85, and 0.84, respectively. When only the RACHS-1 score was used for discrimination, the C statistic values of 30-day, 90-day, and 90-day and in-hospital mortalities for the validation data set were 0.73, 0.73, and 0.77, respectively. CONCLUSIONS: The proposed risk scores and categories have high discrimination power for predicting mortality, demonstrating improvement relative to existing consensus-based methods. Risk models incorporating these measures may be useful for comparing mortality outcomes cross institutions or countries with mixed cases.
