RESUMO
BACKGROUND: In trauma systems, criteria for individualised and optimised administration of tranexamic acid (TXA), an antifibrinolytic, are yet to be established. This study used nationwide cohort data from Japan to evaluate the association between TXA and in-hospital mortality among all patients with blunt trauma based on clinical phenotypes (trauma phenotypes). METHODS: A retrospective analysis was conducted using data from the Japan Trauma Data Bank (JTDB) spanning 2019 to 2021. RESULTS: Of 80,463 patients with trauma registered in the JTDB, 53,703 met the inclusion criteria, and 8046 (15.0%) received TXA treatment. The patients were categorised into eight trauma phenotypes. After adjusting with inverse probability treatment weighting, in-hospital mortality of the following trauma phenotypes significantly reduced with TXA administration: trauma phenotype 1 (odds ratio [OR] 0.68 [95% confidence interval [CI] 0.57-0.81]), trauma phenotype 2 (OR 0.73 [0.66-0.81]), trauma phenotype 6 (OR 0.52 [0.39-0.70]), and trauma phenotype 8 (OR 0.67 [0.60-0.75]). Conversely, trauma phenotypes 3 (OR 2.62 [1.98-3.47]) and 4 (OR 1.39 [1.11-1.74]) exhibited a significant increase in in-hospital mortality. CONCLUSIONS: This is the first study to evaluate the association between TXA administration and survival outcomes based on clinical phenotypes. We found an association between trauma phenotypes and in-hospital mortality, indicating that treatment with TXA could potentially influence this relationship. Further studies are needed to assess the usefulness of these phenotypes.

AIM: There are well-known methods for decompressing the colorectal tract before surgery, including transanal decompression tubes (TDT) and self-expanding metallic stents (SEMS). This study aimed to compare the short and long-term results in patients with malignant large bowel obstruction in whom TDT or SEMS were placed before surgery. METHODS: This retrospective observational study enrolled 225 patients with malignant large bowel obstruction in whom TDT or SEMS were placed preoperatively and underwent R0 resection between 2008 and 2020. One-to-two propensity score matching was performed according to patient characteristics. Short- and long-term outcomes were compared. The primary endpoint was relapse-free survival (RFS). The secondary endpoints were the overall survival (OS) and postoperative complication rate. RESULTS: Fifty-seven patients in the TDT group and 114 in the SEMS group were matched. The 3-year RFS rates were 66.7% in the TDT group and 69.9% in the SEMS group (p = 0.54), and the 3-year OS rates were 90.5% in the TDT group and 87.1% in the SEMS group (p = 0.52). No significant differences in the long-term results were observed between the two groups. Regarding short-term results, the SEMS group had significantly fewer stoma construction (p = 0.007) and shorter postoperative hospitalization (p < 0.001). The incidence of postoperative complications (grade ≥ 2) was significantly lower in the SEMS group (p = 0.04). CONCLUSION: No significant differences in the long-term results were observed between the TDT and SEMS group. The SEMS showed significant usefulness in terms of improving short-term outcomes.

BACKGROUND: Little is known about the transport and outcomes of emergency patients with cardiocerebrovascular diseases in Japan before and during the COVID-19 pandemic.MethodsâandâResults: Data were extracted from a population-based registry in Osaka, Japan, from 2019 to 2021. There were almost no differences in the numbers of emergency patients hospitalized with myocardial infarction, stroke, or heart failure or their deaths. However, the number of cases of difficulty obtaining patient acceptance by hospitals increased in 2020 and 2021 compared with 2019. CONCLUSIONS: The numbers of emergency patients hospitalized with cardiocerebrovascular diseases and their deaths in Osaka were not affected by the COVID-19 epidemic.

The fibrosis-4 index (FIB4), a liver fibrosis maker, has been shown to be associated with the prognosis in patients with severe isolated tricuspid regurgitation (TR). Recent study showed that the fibrosis-5 index (FIB5), which was calculated by albumin, alkaline phosphatase, aspartate transaminase, alanine aminotransferase and platelet count, had better prognostic value than FIB4 in patients with heart failure. The aim of this study was to evaluate the usefulness of FIB5 index for predicting prognosis in patients with severe isolated TR and compare the prognostic value between the FIB4 and the FIB5 in those patients. This was a dual-center, retrospective study. 113 consecutive outpatients with severe isolated TR (mean age, 65.8 years; 47.8% male) were analyzed. Major adverse cardiovascular events (MACEs) were defined as the composite of cardiovascular death, hospitalization for heart failure, myocardial infarction, and stroke. During a median follow-up of 3.0 years, 41 MACEs occurred. Patients with MACEs had a lower the FIB5 than patients without MACEs. The multivariate Cox analysis revealed that the FIB5 < -4.30 was significantly associated with higher incidence of MACEs after adjusted by confounding factors. Receiver-operating characteristic curve analyses showed that prognostic values did not differ between the FIB5 and the FIB4 in whole patients and in patients aged ≥ 70 years; while, in patients aged < 70 years, the FIB5 had better prognostic value than the FIB4. The FIB5 may be a useful predictor of MACEs in patients with severe isolated TR.

INTRODUCTION: Legionella disease can manifest as severe respiratory tract infection with a high mortality rate and is sometimes associated with a hospital outbreak by a contaminated water supply. A patient with breast cancer admitted about a month before. High fever was observed 18 days after admission and the Legionella antigen test showed the positive result. METHODS: Due to the incidence of Legionella infection, we demonstrated the active surveillance of Legionella contamination in the entire hospital. RESULTS: Cultures of her environmental samples revealed that hot water in two bathrooms were contaminated with Legionella. In our hospital, the hot water is heated and pumped up on the roof and distributed to each room. The contaminated bathrooms were related to the same plumbing. Therefore, we further collected samples throughout the hot water system. Legionella was not detected in the central part of the system. However, we detected Legionella in the hot water sampled from other five rooms, which were also associated with the same plumbing of the two bathrooms. The temperature and chlorine concentration of the hot water were not high enough to inactivate Legionella at the end of the plumbing. After the adjustment of the water temperature and chlorine concentration, Legionella became undetectable. Our prompt and active surveillance successfully identified the plumbing of the hot water system as the source of Legionella contamination and took precautions against future outbreaks. CONCLUSIONS: Monitoring of water temperature and chloride concentration at the end of the hot water circulation is important to prevent nosocomial Legionella disease.

PURPOSE: This study compared the surgical outcomes between laparoscopic colectomy (LC) and open colectomy (OC) for mid-transverse colon cancer (MTC). METHODS: This multicenter retrospective study compared the short- and long-term surgical outcomes for patients with advanced MTC (T3 and T4 with or without nodal involvement) who underwent LC or OC between January 2008 and December 2019 using a propensity score-matched analysis. RESULTS: A total of 177 patients with advanced MTC were enrolled. After matching, 58 cases for the OC and LC groups were selected. No significant differences in age, sex, tumor progression, or procedure type (extended resection or segmental resection) existed between groups. The LC group had significantly less blood loss (20 mL vs. 50 mL, p=0.048) and a shorter postoperative hospital stay (8 days vs. 12 days, p<0.001) than the OC group. Postoperative complications (Clavien-Dindo grade ≥ 2) occurred in 27.6% and 25.9% of the OC and LC groups respectively (p=1). Three patients (5.2%) and one patient (1.7%) of the OC and LC groups respectively developed anastomotic leakage (p=0.62). Re-operation was required in five patients (8.6%) in the OC group and one patient (1.7%) in the LC group (p=0.21). No surgery-related deaths occurred in either group. The 3-year overall survival rates (stage II: LC 100% vs. OC 92.8%, p=0.15; stage III: 88.9% vs. 84.3%, p=0.88, respectively) were similar between the two groups. CONCLUSION: LC is a minimally invasive technique with lesser blood loss, shorter postoperative hospital stays, and oncologic equivalence to OC. Hence, LC is useful for MTC treatment.

PURPOSE: Computed tomography (CT) has become essential for the management of trauma patients. However, appropriate timing of CT acquisition remains undetermined. The purpose of this study was to assess the relationship between time to CT acquisition and mortality among adult patients with severe trauma. METHODS: We conducted a retrospective cohort study using data from the Japan Trauma Data Bank, which had 256 participating institutions from all over Japan between 2004 and 2018. Patients were categorized upon arrival as either severe trunk trauma with signs of shock or severe head trauma with coma and separately analyzed. Cases were further divided into three groups based on time elapsed between arrival at hospital and CT acquisition as immediate (0-29 min), intermediate (30-59 min), or late (≥60 min). Primary outcome was mortality on discharge, and multivariate logistic regression with adjusting for confounders was used for evaluation. RESULTS: A total of 8467 (3640 in immediate group, 3441 in intermediate group, 1386 in late group) with trunk trauma patients and 6762 (4367 in immediate group, 2031 in intermediate group, 364 in late group) with head trauma patients were eligible for analysis included in the trunk and head trauma groups, respectively. The trunk trauma patients with shock on hospital arrival was 56.4% (4773/8467), and the head trauma patients with deep coma upon EMS arrival was 44.2% (2988/6762). Mortality rate gradually increased from 5.7% to 15.8% with prolonged time to CT imaging among trunk trauma patients. Multivariate logistic regression for death on discharge among trunk trauma patients yielded an adjusted odds ratio of 1.79 (95% confidence interval: 1.42-2.27) for the late group compared to the immediate group. In contrast, among head trauma patients, an adjusted odds ratio was 0.93 (95% confidence interval: 0.71-1.20) for the late group compared to the immediate group. CONCLUSION: CT scan at or after 60 min was associated with increased death on discharge among patients with severe trunk trauma but not in those with severe head trauma.
RESUMO
BACKGROUND AND OBJECTIVES: Contrary to the Japanese guidelines recommendations regarding lateral lymph node dissection (LatLND) for rectal cancer, its omission is common in clinical practice without reliable omission criteria. Negative pathological mesorectal lymph node metastasis (MesLNM) is reportedly highly correlated with negative pathological lateral lymph node metastasis (p-LatLNM); however, this cannot be used as a criterion because pathological features are revealed postoperatively. Herein, we prospectively evaluated the negative predictive value (NPV) of MesLNM diagnosed via the one-step nucleic acid amplification (OSNA) method for p-LatLNM. METHODS: This prospective study was conducted at a single academic study group in Japan. The key eligibility criterion was mid-to-low rectal cancer planned to be treated using mesorectal excision with LatLND. According to the study protocol, the OSNA method was considered useful if the point estimate of the NPV exceeded 95%. RESULTS: Preoperative case registration was conducted between 2018 and 2020; 34 patients were registered. Among these, 16 were negative for OSNA-MesLNM, and negative p-LatLNM was confirmed in all cases. The point estimate of the NPV was 100%, with the 95% confidence interval ranging from 79.4% to 100.0%. CONCLUSIONS: The OSNA method is useful in selecting patients in whom LatLND can be omitted in real-world clinical practice.

BACKGROUND: The fibrosis-4 (FIB-4) index is used to evaluate liver disease patients. It can also be used to evaluate the prognosis for heart disease patients; however, its ability to determine the prognosis of severe isolated tricuspid regurgitation (TR) patients is unclear. This study aimed to clarify the association between FIB-4 index scores and the cardiovascular prognosis for severe isolated TR patients.MethodsâandâResults: This was a dual-center, retrospective study. From 2011 to 2019, 111 consecutive outpatients with severe isolated TR (mean age, 68.6 years; 53.2% male) were evaluated. Major adverse cardiovascular events (MACEs) were defined as the composite of cardiovascular death, hospitalization for heart failure, myocardial infarction, and stroke. The association between FIB-4 index scores and echocardiography was also evaluated. During a median follow up of 3.0 years, 24 patients were lost to follow up and 40 MACEs occurred. Baseline FIB-4 index scores for patients with MACEs were significantly higher than those for patients without MACEs. A multivariate analysis revealed that FIB-4 index scores are significantly associated with MACEs (hazard ratio, 1.89; 95% confidence interval, 1.01-3.54; P=0.046). A linear regression analysis indicated that FIB-4 index scores were correlated with echocardiographic parameters, including the left atrial volume index and left ventricular end-diastolic diameter. CONCLUSIONS: The FIB-4 index score may be a useful predictor of MACEs for patients with severe isolated TR.

BACKGROUND: Trauma is a heterogeneous condition, and specific clinical phenotypes may identify target populations that could benefit from certain treatment strategies. In this retrospective study, we determined clinical phenotypes and identified new target populations of trauma patients and their treatment strategies. METHODS: We retrospectively analyzed datasets from the Japan Trauma Data Bank and determined trauma death clinical phenotypes using statistical machine learning techniques and evaluation of biological profiles. RESULTS: The analysis included 71,038 blunt trauma patients [median age, 63 (interquartile range [IQR], 40-78) years; 45,479 (64.0%) males; median Injury Severity Score, 13 (IQR, 9-20)], and the derivation and validation cohorts included 42,780 (60.2%) and 28,258 (39.8%) patients, respectively. Of eight derived phenotypes (D-1-D-8), D-8 (n = 2178) had the highest mortality (48.6%) with characteristic severely disturbed consciousness and was further divided into four phenotypes: D-8α, multiple trauma in the young (n = 464); D-8ß, head trauma with lower body temperature (n = 178); D-8γ, severe head injury in the elderly (n = 957); and D-8δ, multiple trauma, with higher predicted mortality than actual mortality (n = 579). Phenotype distributions were comparable in the validation cohort. Biological profile analysis of 90 trauma patients revealed that D-8 exhibited excessive inflammation, including enhanced acute inflammatory response, dysregulated complement activation pathways, and impaired coagulation, including downregulated coagulation and platelet degranulation pathways, compared with other phenotypes. CONCLUSIONS: We identified clinical phenotypes with high mortality, and the evaluation of the molecular pathogenesis underlying these clinical phenotypes suggests that lethal trauma may involve excessive inflammation and coagulation disorders.

PURPOSE: The laparoscopic surgery approach for mid-transverse colon cancer (MTC) varies depending on tumor characteristics and the guidelines implemented by each surgeon; the optimal surgical procedure for MTC has not been established. This study aimed to compare the surgical outcomes of laparoscopic extended right hemicolectomy (Lap-ERHC) and laparoscopic transverse colectomy (Lap-TC) for MTC. METHODS: This was a multicenter, retrospective study. We surveyed eight hospitals, by questionnaire, on MTC surgery policies and retrospectively compared the short- and long-term surgical outcomes for patients with MTC who underwent Lap-ERHC or Lap-TC between January 2008 and December 2019. RESULTS: A total of 129 patients were enrolled, of whom 35 underwent Lap-ERHC and 94 underwent Lap-TC. There were no significant differences in tumor progression between the two groups. Operation time was significantly longer (202 min vs. 185 min, p = 0.026). We observed a higher complication rate (≥ grade 3) in the Lap-ERHC group than in the Lap-TC group (11.4% vs. 3.2%, p = 0.086). Three patients (8.6%) who underwent Lap-ERHC developed anastomotic leakage; none of the patients who underwent Lap-TC had this complication (p = 0.018). The 3-year overall survival rates (stage I: 100% vs. 91.9%, p = 0.64; stage II: 100% vs. 95.5%, p = 0.46; stage III: 100% vs. 88.2%, p = 0.91, respectively) were similar between the two groups. CONCLUSION: Lap-ERHC for MTC has the same long-term outcomes as Lap-TC. However, Lap-ERHC for MTC has a higher complication rate. Therefore, Lap-TC may be recommended for patients with MTC.

INTRODUCTION: Postpartum haemorrhage is a major cause of maternal mortality. Although contrast-enhanced computed tomography (CE-CT) is useful to reveal arterial bleeding, its accuracy in postpartum haemorrhage is unclear. The aim of this study was to evaluate the accuracy of CE-CT scanning in detecting postpartum haemorrhage. METHODS: This was a retrospective observational study. We included patients with postpartum haemorrhage treated by emergency physicians in collaboration with obstetricians. We calculated the sensitivity, specificity, and positive and negative predictive values for CE-CT scanning to detect arterial bleeding. RESULTS: CE-CT scanning was performed in 52 patients, and 31 patients had extravasation. The sensitivity of CE-CT scanning to detect arterial extravasation was 100% (15/15), specificity was 28.6% (2/7), positive predictive value was 75% (15/20), and negative predictive value was 100% (2/2). CONCLUSION: We showed the sensitivity of CE-CT scanning to detect arterial extravasation in patients with postpartum haemorrhage to be 100%.

BACKGROUND: Coronavirus disease 2019 (COVID-19), caused by Severe Acute Respiratory Syndrome Coronavirus 2, has spread rapidly around the world. OBJECTIVE: To assess the effect of the COVID-19 pandemic on the emergency medical service (EMS) and hospital admission course for children transported by ambulance. METHODS: This study was a retrospective, descriptive study with a study period from January 1, 2018 to December 31, 2020 using the Osaka Emergency Information Research Intelligent Operation Network (ORION) system. All children who were transported by ambulance in Osaka Prefecture were included. The main outcome of this study was the rate of difficult-to-transfer cases, which was calculated by univariate and multivariate Poisson regression analyses. RESULTS: Over the 3 years between January 1, 2018 and December 31 2020, 1,436,212 patients were transported to hospitals by ambulances in Osaka Prefecture, with children accounting for 102,473 (37,064, 39,590, and 25,819, in 2018, 2019, and 2020, respectively). Poisson regression analysis showed that children were negatively associated with difficult-to-transfer cases (risk ratio (RR) 0.35, 95% CI 0.33 to 0.37). With reference to 2018, 2020 was not significantly associated with difficult-to-transfer cases in children (RR 1.14, 95% CI 0.99 to 1.32, P = 0.075), but was significantly related (RR 1.24, 95% CI 1.21 to 1.27, P < 0.001) to difficult-to-transfer cases in the general population. CONCLUSION: Children were consistently associated with a reduced RR for difficult-to-transfer cases, even in the COVID-19 pandemic in 2020.

BACKGROUND: Earlier syndromic surveillance may be effective in preventing the spread of infectious disease. However, there has been no research on syndromic surveillance for rotavirus. The study aimed to assess the relationship between the incidence of rotavirus infections and the number of telephone triages for associated symptoms in pediatric patients under 4 years old in Osaka prefecture, Japan. METHODS: This was a retrospective observational study for which the study period was the 3 years between January 2015 and December 2017. We analyzed data on children under 4 years old who were triaged by telephone triage nurses using software. The primary endpoint was the number of rotavirus patients under 4 years triaged old per week. Using a linear regression model, we calculated the R square value of the regression model to assess the relationship between the number of patients with rotavirus and the number of telephone triages made for associated symptoms. Covariates in the linear regression model were the week number indicating seasonality and the weekly number of telephone triages related to rotavirus symptoms such as stomachache and vomiting. RESULTS: During the study period, there were 102,336 patients with rotavirus, and the number of people triaged by telephone was 123,720. The highest correlation coefficient was 0.921 in the regression model with the number of telephone triages for "stomachache + nausea/vomiting" and "stomachache + diarrhea + nausea/vomiting". CONCLUSION: The number of telephone triage symptoms was positively related to the incidence of pediatric patients with rotavirus in a large metropolitan area of Japan.

BACKGROUND: Little is known about the characteristics of emergency patients transported to hospital while participating in sports activity. Hence, we identified characteristics of emergency patients transported to hospital by emergency medical service (EMS) while participating in sports activity in Osaka City. METHODS: Population-based ambulance records of Osaka Municipal Fire Department were reviewed. All sports-related emergency transport cases (ie, patients experiencing external injury or illness during/immediately after participation in sports activity and then transported to hospital by the EMS) were enrolled, including both athletes and recreational sports participants. The study was performed from January 1, 2013 to December 31, 2015. Data of patient characteristics were described according to the type of sports. RESULTS: During the study, 661,190 patients required emergency transport in Osaka city; 2,642 (0.4%) were sports-related emergency transport, including 2,453 external injuries and 298 illnesses. Overall, 79.0% of patients were men and 44.4% were less than 18 years. Emergency transport during ball games accounts for the majority of cases (71.5%, 1,888/2,642), including baseball (n = 380), soccer (n = 368), and futsal (n = 209). The leading diagnosis/symptom of external injury was fracture/bone contusion (n = 701) and that of illness was heatstroke/dehydration (n = 184). Serious acute illness, such as sudden cardiac arrest, accounted for 0.6% (16/2,751) of all accidents, with half of them (n = 8) related to long-distance running. CONCLUSION: Characteristics of sports-related accidents widely varied by type of sports. Measures to prevent serious accidents during sports activities should be established based on the information on patient characteristics of each type of sports.

We report a rare case of spindle cell carcinoma of the breast which grew rapidly during neoadjuvant chemotherapy. A 72- year-old female was presenting with chief complaint of a mass in the right breast; a tumor about 20 mm in size. Core needle biopsy of tumor revealed invasive ductal carcinoma and fine needle aspiration cytology of axillary lymph node was Class â ¤. So she was diagnosis breast cancer as cT2N1M0, cStage â ¡B. The tumor subtype was triple negative breast cancer (TNBC). She received the neoadjuvant chemotherapy by FEC100. After FEC 4 courses, we detected a huge and rapid growing breast mass of 40 mm by CT. She was administered received mastectomy and axillary lymph node dissection after 4 months from initial contact. Pathological finding was spindle cell carcinoma of the breast. Postoperatively, she was treated with weekly PTX for a total of 12 courses and radiation therapy for a right chest wall and supraclavicular fossa. Although the tumor was resistant for neoadjuvant chemotherapy, she is alive and well without metastasis for more than 3 years.

A 61-year-old man had a sudden severe abdominal pain and visited our hospital. He was diagnosed with intestinal perforation, given the peritoneal irritation symptoms, the thickening of the intestinal wall and free air as shown on enhanced abdominal computed tomography. He then underwent emergent surgery. A tumor with small perforation was found on the intestine about 15 cm distant from the terminal ileum. Partial resection of the ileum was performed. Microscopically, a type 2 tumor of 70×50mm in diameter, was observed in the resected intestine. The tumor was diagnosed as diffuse large B-cell lymphoma via immunochemical staining. He received 6courses of R-CHOP therapy after surgery without recurrence. A primary intestinal malignant lymphoma is easily perforated, which lead to poor prognosis of the patient. We report a case of perforated intestinal malignant lymphoma, which was induced to remission by multidisciplinary therapy.

Appendiceal mucinous neoplasm has a risk for pseudomyxoma peritonei caused by appendiceal perforation.It has been reported that laparoscopic surgery is more risky than open surgery.We investigated 4 patients who underwent laparoscopic surgery for appendiceal mucinous neoplasm.The median age was 69.5(49-85).There were 3 males and 1 female.Three cases of partial laparoscopic resection of the cecum and 1 case of ileocecal resection with lymph node dissection were performed. The pathology was low-grade mucinous neoplasm in all cases.The median hospital stay was 6 days, and there were no postoperative complications(CD Grade 3 or higher)or hospital death.As for long-term results, peritoneal pseudomyxoma developed in 1 case, which had already ruptured at the time of surgery.There were no recurrences in other cases.This result suggests that laparoscopic surgery for appendiceal mucinous neoplasm is safe with optimal selection of the procedure and a protective technique.

A 69-year-old woman was referred to our hospital due to dyspnea on exertion and a heart murmur. A chest X-ray showed a bulge at the left 3rd arch and chest computed tomography( CT) revealed a giant mass adjacent to the right ventricular outflow. Multidetector-row CT and coronary angiography showed a giant coronary aneurysm (55×45 mm) and fistulae arising from the left main coronary trunk and entering into the main pulmonary artery (PA). The pulmonary to systemic flow ratio was 1.84. She was diagnosed with coronary-pulmonary artery fistulae with giant coronary aneurysm. Aneurysmorrhaphy and closure of the fistula outlet from the PA were performed under cardiopulmonary bypass with cardiac arrest. After declamping the aorta, residual shunt flow was found at several sites of abnormal vessels in the right ventricular outflow using a Doppler flowmeter. The vessels were ligated with pledgeted sutures, but did not disappear completely. Postoperative coronary angiography and transthoracic echocardiogram showed a small residual shunt flow into the PA. The postoperative course was uneventful;she was discharged on postoperative day 18. Six months later, the residual shunt flow had disappeared. No recurrence has been detected for 7 years.

BACKGROUND: Characteristics and outcomes of emergency patients with bath-related sudden cardiac arrest in prehospital settings have not been sufficiently investigated. METHODSâANDâRESULTS: From a prospective population-based registry, which covers all out-of-hospital cardiac arrests (OHCAs) in Osaka City, a total of 642 patients who had a bath-related OHCA from 2012 to 2014 were enrolled in the analyses. The characteristics and outcomes of OHCA were compared by three locations of arrest: home baths (n=512), public baths (n=102), and baths in other public institutions (n=28). Overall, bath-related OHCAs mainly occurred in winter (December-February, 48.9%, 314/642). The proportion of OHCAs that were witnessed by bystanders was 6.4% (33/512) in home baths, 17.6% (18/102) in public baths, and 25.0% (7/28) in baths in other public institutions. The proportion of public-access automated external defibrillator pad application was 0.8% (4/512) in home baths, 6.9% (7/102) in public baths, and 50.0% (14/28) in baths in other public institutions. Only 1 survivor with a favorable neurologic outcome was observed in a home bath, whereas there were no patients who survived with favorable neurologic outcomes in public baths and baths in other public institutions. CONCLUSIONS: Bath-related OHCAs mainly occurred in winter, and the outcome of victims was exceedingly poor, irrespective of location of arrest. The establishment of preventive measures as well as earlier recognition of cardiac arrest by bystanders are needed. (Circ J 2016; 80: 1564-1570).
