RESUMO
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.

BACKGROUND: Shoulder and elbow examinations for pitchers have been performed in Japan's National High School Baseball Invitational Tournaments (NHSBITs) and National High School Baseball Championships (NHSBCs) since 1993. However, for years the results have not been analyzed. The purpose of this study was to evaluate changes in the condition of shoulders and/or elbows of pitchers from 1993 to 2016. MATERIALS AND METHODS: Pitchers in NHSBITs and NHSBCs, 1994-2016, were examined together with those who received a trial examination (Trial) in the NHSBC 1993. Shoulder and elbow symptoms were comprehensively graded into five categories; none, mild, moderate, severe and dysfunction. Standard plain radiographs of the shoulder and elbow were obtained. Average Annual Percent Changes (AAPCs) in the percentages of pitchers with symptoms and positive radiographic findings were analyzed. RESULTS: The percentages of pitchers with moderate or worse symptoms in the shoulder or elbow were 14.6% and 13.8%, respectively, in the Trial, 1.1% and 1.1% in NHSBITs and 1.3% and 2.0% in NHSBCs. The AAPC of pitchers with a symptomatic shoulder in NHSBITs was reduced over the study period, at -3.36% (P < 0.05), but that in NHSBCs was unchanged at -1.01%. The AAPCs of pitchers with a symptomatic elbow in NHSBITs and in NHSBCs decreased, at -3.13% and -3.33%, respectively (P < 0.05), while that of pitchers with residual apophyseal fragmentation at the ulnar collateral ligament insertion increased at +2.79% (P < 0.05). The decreased percentages of symptomatic pitchers suggest that joint condition is well controlled in high school days; however, the increased frequency of radiographic findings suggests the necessity of protection against overuse in younger players. CONCLUSIONS: The percentages of pitchers with symptomatic shoulders and elbows in NHSBITs and those with symptomatic elbows in NHSBCs have decreased over the 23 years. However, the increased frequency of residual medial humeral epicondyle apophyseopathy should be noted.

The effect of post-cardiac arrest care in children with out-of-hospital cardiac arrest (OHCA) has not been adequately established, and the long-term outcome after pediatric OHCA has not been sufficiently investigated. We describe here detailed in-hospital characteristics, actual management, and survival, including neurological status, 90 days after OHCA occurrence in children with OHCA transported to critical care medical centers (CCMCs).We analyzed the database of the Comprehensive Registry of Intensive Care for OHCA Survival (CRITICAL) study, which is a multicenter, prospective observational data registry designed to accumulate both pre- and in-hospital data on OHCA treatments. We enrolled all consecutive pediatric patients aged <18 years who had an OHCA and for whom resuscitation was attempted and who were transported to CCMCs between 2012 and 2016.A total of 263 pediatric patients with OHCA were enrolled. The average age of the patients was 6.3 years, 38.0% were aged < 1 year, and 60.8% were male. After hospital arrival, 4.9% of these pediatric patients received defibrillation; 1.9%, extracorporeal life support; 6.5%, target temperature management; and 88.2% adrenaline administration. The proportions of patients with 90-day survival and a pediatric cerebral performance category (PCPC) score of 1 or 2 were 6.1% and 1.9%, respectively. The proportion of patients with a PCPC score of 1 or 2 at 90 days after OHCA occurrence did not significantly improve during the study period.The proportion of pediatric patients with a 90-day PCPC score of 1 or 2 transported to CCMCs was extremely low, and no significant improvements were observed during the study period.

Coffee consumption is increasing globally. We aimed to assess the effect of coffee consumption on the risk of all-cause and cause-specific mortality in a pooled analysis of eight population-based cohort studies in Japan (Japan Cohort Consortium). Data came from eight Japanese cohort studies (144,750 men and 168,631 women). During a mean follow-up time of 17â¯years, 52,943 deaths occurred. More specifically, 19,495 cancer deaths, 7321 deaths due to heart disease, 6387 cerebrovascular, 3490 respiratory disease and 3382 injuries and accidents. A random effects model was applied to obtain pooled hazard ratios (HRs) and 95% confidence intervals (95%CIs). In both sexes, coffee consumption up to 5â¯cups/day was overall protective in relation to all-cause mortality, with the association attenuating in the highest category of coffee consumption (≥5â¯cups/day). In men, a similar inverse association was observed for major causes of mortality except cancer. In women, coffee consumption decreased the risk for mortality due to heart disease in the 1-2â¯cups/day category, but increased the risk in the ≥5â¯cups/day category. Coffee consumption was not associated with cancer in both sexes. Results were similar among male current smokers and female never-smokers. Based on available data, this pooled analysis suggests that coffee consumption under five cups per day may be beneficial for reducing the risk of mortality due to major causes.

AIMS: We aimed to reveal the effects of application of public-access automated external defibrillators (AEDs) and bystander-initiated cardiopulmonary resuscitation (CPR) on survival of paediatric patients with out-of-hospital cardiac arrest (OHCA) occurring on school campuses in Japan. METHODS AND RESULTS: Data were obtained from a nationwide prospective observational study of paediatric OHCAs in school settings in Japan, termed Stop and Prevent cardIac aRrest, Injury, and Trauma in Schools (SPIRITS). Non-traumatic OHCA patients from elementary school, junior high school, and high school/technical college between April 2008 and December 2015 were enrolled. A multivariable logistic regression analysis was conducted to assess the effect of bystander interventions (i.e. public-access AED application and bystander-CPR) on 30-day survival with favourable neurological outcome. In total, 232 OHCA cases were analysed. The proportion of 30-day survival with favourable neurological outcome was significantly higher among the patients receiving both public-access AED application and bystander-CPR than those without any bystander intervention (50.9% vs. 20.0%, adjusted odds ratio 4.08, 95% confidence interval 1.25-13.31; P = 0.020). During the study period, the proportion of patients to whom public-access AEDs were applied increased significantly (from 61.9% in 2008 to 87.0% in 2015, P-for trend = 0.014). Accordingly, the proportion of 30-day survival with favourable neurological outcome improved significantly (from 38.1% in 2005 to 56.5% in 2015, P-for trend = 0.026). CONCLUSION: The combination of public-access AED application and bystander-CPR increased the chance of survival approximately four-fold in schools. The nationwide efforts towards disseminating public-access defibrillation systems in school settings may reduce the risk of sudden cardiac death among school children.

BACKGROUND: Coffee, which contains various bioactive compounds, is one of the most popular beverages. Further accumulation of evidence is needed, however, to confirm whether coffee consumption would be effective in preventing cardiovascular disease in the general Japanese population. MethodsâandâResults: We evaluated the association between coffee consumption frequency (never, sometimes, 1-2 cups/day, 3-4 cups/day and ≥5 cups/day) and mortality from all causes, heart disease, and cerebrovascular disease, in 39,685 men and 43,124 women aged 40-79 years at baseline, in a 3-prefecture cohort study. The coffee consumption frequency was assessed on questionnaire. Cox proportional hazards regression modeling was used to assess the association between coffee consumption frequency and all-cause and cardiovascular disease mortality with adjustment for potential confounders. During 411,341 and 472,433 person-years in men and women, respectively, a total of 7,955 men and 5,725 women died. Coffee consumption frequency was inversely associated with all-cause mortality in both genders (P for trend<0.001). In addition, the risks of mortality from cerebrovascular disease in men (P for trend<0.001), and heart disease in women (P for trend=0.031) were inversely associated with coffee consumption. CONCLUSIONS: In this Japanese population, coffee drinking has a preventive effect on all-cause and on cardiovascular mortality in men and/or women.

The aim of our study was to assess the association between green tea consumption and all-cause and cause-specific mortality in a pooled analysis of eight Japanese population-based cohort studies. Pooled hazard ratios (HR) and 95% confidence intervals (CI), derived from random effects models, were used to evaluate the associations between green tea consumption, based on self-report at baseline, and risk of all-cause and cause-specific mortality. During a mean follow-up of 17.3 years, among 313,381 persons, 52,943 deaths occurred. Compared with individuals who consumed < 1 cup/day, those in the highest consumption category (≥ 5 cups/day) had a decreased risk of all-cause mortality [the multivariate-adjusted HR was 0.90 (95% CI 0.87-0.94) for men and 0.82 (0.74-0.90) for women]. A similar inverse association was observed for heart disease mortality [HR 0.82 (0.75-0.90) for men, and 0.75 (0.68-0.84) for women], and cerebrovascular disease mortality [HR 0.76 (0.68-0.85) for men, and 0.78 (0.68-0.89) for women]. Among women, green tea consumption was associated with decreased risk of total cancer mortality: 0.89 (0.83-0.96) for the 1-2 cups/day category and 0.91 (0.85-0.98) for the 3-4 cups/day category. Results for respiratory disease mortality were [HR 0.75 (0.61-0.94)] among 3-4 cup daily consumers and [HR 0.66 (0.55-0.79)] for ≥ 5 cups/day. Higher consumption of green tea is associated with lower risk for all-cause mortality in Japanese, especially for heart and cerebrovascular disease. Moderate consumption decreased the risk of total cancer and respiratory disease mortality in women.

BACKGROUND: We assessed whether the occurrence of out-of-hospital cardiac arrest (OHCA) with cardiac origin increased in the disaster areas during the 3-year period after the Great East Japan Earthquake (GEJE).MethodsâandâResults:From the OHCA registry in Japan, yearly changes in occurrence after the GEJE were assessed by applying Poisson regression models. The risk ratio of the first year after the earthquake was significantly greater in both men and women, but the difference disappeared in the second and third years. CONCLUSIONS: The GEJE significantly increased the occurrence of OHCA with cardiac origin in the first year after the earthquake.

BACKGROUND: A better understanding of the epidemiology of pediatric out-of-hospital cardiac arrest (OHCA) occurring in school settings is important to establish an evidence-based strategy for prevention and better prognosis.MethodsâandâResults:The Stop and Prevent cardIac aRrest, Injury, and Trauma in Schools (SPIRITS) is a nationwide prospective observational study linking databases from 2 nationally representative registries, the Injury and the Accident Mutual Aid Benefit System of The Japan Sport Council and the All-Japan Utstein Registry of the Fire and Disaster Management Agency. Using these databases, we described the detailed characteristics and outcomes of pediatric OHCAs that occurred in school settings in Japan between 2009 and 2014. During the 6-year study period, 295 OHCA cases were confirmed. Overall incidence rate was 0.4 per 100,000 students per year. The majority of OHCA cases had a cardiac origin (71%), occurred during exercise (65%), were witnessed by bystanders (70%), and received bystander-initiated cardiopulmonary resuscitation (73%). In approximately one-third of cases the student was defibrillated by public-access automated external defibrillator (38%). The proportion of patients with 1-month survival and a favorable neurological outcome was 34% among all OHCAs and 43% among OHCAs of cardiac origin. CONCLUSIONS: In Japan, approximately 50 pediatric cases of OHCA consistently occur yearly in school settings. The majority of students received basic life support from bystanders, and patients with OHCA of cardiac origin had a relatively good prognosis.

The preventive effect of coffee on cancer at different sites has been reported, but the effect on all-sites cancer incidence has not been extensively investigated. We evaluated the association between frequency of coffee consumption and risk of all-sites cancer incidence and mortality among 39 685 men and 43 124 women (age 40-79 years, at baseline), in the Three-Prefecture Cohort Study. The association between frequency of coffee consumption and risk of all-sites cancer incidence and mortality was assessed by a Cox proportional hazards regression model, adjusted for potential confounders. During 411 341 person-years among men and 472 433 person-years among women, a total of 4244 men and 2601 women developed cancer at different sites and a total of 3021 men and 1635 women died of cancer at different sites. We showed an inverse association between frequency of coffee consumption and all-sites cancer incidence in both men and women. Comparing participants who consumed coffee with those who never drank coffee, the adjusted hazard ratios (95% confidential interval) for all-sites cancer incidence was 0.74 (0.62-0.88) for coffee consumption of ≥5 cups/day in men (P for trend < 0.001) and 0.76 (0.58-1.02) in women (P for trend = 0.020). Coffee consumption frequency was inversely associated with mortality from all-sites cancer. In this population, increasing coffee consumption resulted in a decreased risk of all-sites cancer incidence and mortality.

BACKGROUND: We reutilized the existing Three-Prefecture Cohort to evaluate the relationship between lifestyle factors and the incidence or mortality from non-communicable diseases. METHODS: This study was a prospective population-based observation conducted from the 1980s to 2000 in three prefectures (Miyagi, Aichi, and Osaka) in Japan. The study subjects were residents aged ≥40 years who received a questionnaire. The follow-up period was 15 years from the baseline survey in each study area. A self-administered questionnaire, which included items on participants' demographic factors and lifestyle characteristics, was administered. Vital status and date of death were collected from residence certificates by the local government, and cause of death was identified using vital statistics. Cancer incidence and the date of diagnosis were collected from local cancer registry data. RESULTS: A total of 46,421 men and 54,189 women were eligible for our analysis. The person-years of follow-up for cancer incidence were 464,664 and 567,271 for men and women, respectively, and those for death were 527,940 and 648,601 for men and women, respectively. There were 8479 cancer incidences (5106 men and 3373 women) and 20,240 total deaths (11,156 men and 9084 women). The stomach was the most common cancer incidence site for both men (25.6%) and women (18.6%). The leading cause of death was cancer among men (35.0%) and cardiovascular disease among women (41.0%). CONCLUSIONS: The Three-Prefecture Cohort Study enabled us to reveal the association of multiphasic lifestyle factors with cancer incidence and mortality. The study will also allow us to conduct a pooled analysis in combination with other large-scale cohorts.

OBJECTIVE: This study aimed to examine epidemiologically socio-environmental factors associated with diabetes mellitus among patients hospitalized with schizophrenia in Japan. METHODS: This was a cross-sectional study from a single psychiatric hospital. Study patients were adults aged ≥20 years who were hospitalized with schizophrenia one or more times between January 2013 and December 2014. From electronic medical records or health insurance claims, we extracted schizophrenia patients with an F2 code according to ICD-10, and assessed the association of various factors with diabetes mellitus among these patients in a multivariable analysis. RESULTS: During the 2-year period, there were 1899 patients hospitalized with a psychiatric disorder one or more times. Of them, a total of 770 adults with schizophrenia (285 men and 485 women) were eligible for our analysis. The standardized prevalence ratio of diabetes mellitus was 2.0 [95 % confidence interval (CI) 1.6-2.5] among men and 3.0 (95 % CI 2.5-3.6) among women in this hospital. There were no socio-environmental factors associated with diabetes mellitus among men. Among women, factors such as a 730-day hospitalization [adjusted odds ratio (OR) 3.82: 95 % confidence interval (CI) 1.52-9.64], and a medical protection/compulsory/discrimination hospitalization (adjusted OR 0.60, 95 % CI 0.36-0.99) were associated with diabetes mellitus. Compared with women living alone, those who were unmarried and lived together with someone had a significantly lower adjusted OR (0.41, 95 % CI 0.21-0.81). CONCLUSIONS: Socio-environmental factors such as length of hospitalization, type of hospitalization, and marital status and living arrangement were associated with diabetes mellitus among hospitalized women with schizophrenia.

PURPOSE: Posttraumatic meningitis is one of the severe complications that can result in increased mortality and longer hospital stay among trauma patients. Factors such as cerebrospinal fluid (CSF) fistula and basilar skull fracture are associated with posttraumatic meningitis. However, it remains unclear whether procedures such as burr hole surgery in the emergency department and decompressive craniectomy are associated with posttraumatic meningitis. The aim of this study was to assess factors associated with posttraumatic meningitis with a nationwide hospital-based trauma registry in Japan. METHODS: This was a retrospective observational study with a 12-year study period from January 2004 to December 2015. We included trauma patients registered in the Japanese Trauma Data Bank, whose head Abbreviated Injury Scale score was ≥ 3 in this study. The main endpoint was the occurrence of meningitis during hospitalization. Multivariable logistic regression analysis was used to assess independent parameters associated with posttraumatic meningitis such as CSF fistula, burr hole surgery in the emergency department, and decompressive craniectomy. RESULTS: Among 60,390 head injury patients with head AIS score 3 or more, 284 (0.5%) patients had posttraumatic meningitis. Factors associated with posttraumatic meningitis were burr hole surgery in the emergency department (adjusted odds ratio [AOR] 2.158 [95% confidence interval (CI) 1.401-3.325]), decompressive craniectomy (AOR 2.123 [95% CI 1.506-2.993]), external ventricular drainage (AOR 1.843 [95% CI, 1.157-2.935]), CSF leakage (AOR 3.328 [95% CI 2.205-5.022]), and basilar skull fracture (AOR 1.651 [95% CI 1.178-2.314]). CONCLUSIONS: In this population of trauma patients, burr hole surgery in the emergency department and decompressive craniectomy was associated with posttraumatic meningitis.

PURPOSE: The aim of this study was to evaluate the association between the implementation of pelvic angiography (PA) and outcome in emergency pediatric patients with pelvic fracture. METHODS: We extracted data on pelvic fracture patients aged ≤ 19 years between 2004 and 2015 from a nationwide trauma registry in Japan. The main outcome was hospital mortality. We assessed the relationship between implementation of PA and hospital mortality using one-to-one propensity-score-matching analysis to reduce potential confounding effects in comparing the PA group with the non-PA group. RESULTS: In total, 1351 patients were eligible for our analysis, with 221 patients (16.4%) included in the PA group and 1130 patients (83.6%) included in the non-PA group. For all patients, the proportion of hospital mortality was higher in the PA group than in the non-PA group [13.6% (30/221) vs 7.1% (80/1130), crude odds ratio (OR) 2.062 (95% confidence interval (CI), 1.318-3.224); p = 0.002]. In the propensity-score-matched patients, the proportion of hospital mortality was lower in the PA group than in the non-PA group [10.5% (22/200) vs 18.2% (38/200), p = 0.027]. This finding was confirmed in both the multivariable logistic regression model [adjusted OR 0.392 (95% CI, 0.171-0.896); p = 0.026] and the conditional logistic regression model [conditional OR 0.484 (95% CI, 0.261-0.896); p = 0.021]. CONCLUSION: The implementation of PA was significantly associated with lower hospital mortality among emergency pediatric patients with pelvic fractures compared with the non-implementation of PA.

AIM: The study examined the association of vehicle seating positions with the risk of death in serious motor vehicle crashes (MVCs) in Japan. METHODS: Data from the Japan Trauma Data Bank between 2004 and 2015 were analyzed. All MVC drivers with the legal age for driving and all copassengers were enrolled (n = 23,040). The cases were divided into three groups based on their seating position during the crash: the driver seat, front passenger seat, and rear passenger seats. The primary outcome variable was in-hospital mortality. Multivariable logistic regression analysis was used to assess the association between the seating position and in-hospital mortality. Potential factors associated with each seating position and in-hospital mortality were also assessed. RESULTS: The odds ratios (ORs) for deaths were estimated for front and rear passengers compared to those for the driver in MVCs. The adjusted ORs (95% confidence interval [CI]) for death were 0.96 (0.84-1.11) and 1.22 (1.04-1.42) for front and rear passengers, respectively. Factors significantly associated with MVC deaths were age over 71 years (OR = 3.38; 95% CI, 2.58-4.41), male gender (OR = 1.54; 95% CI, 1.39-1.71), and night driving (OR = 1.17; 95% CI, 1.06-1.29). CONCLUSIONS: This hospital-based study suggested that rear seating increased the risk of MVC-related death. Further studies are needed in order to find mechanisms of the increase in mortality by the seating position.
RESUMO
BACKGROUND: Little is known about the association between prehospital cardiopulmonary resuscitation duration for adults with out-of-hospital cardiac arrest and outcome by the location of arrests. This study aimed to investigate the association between prehospital cardiopulmonary resuscitation duration and one-month survival with favourable neurological outcome. METHODS: We analysed 276,391 adults aged 18 years and older with out-of-hospital cardiac arrest of medical origin before emergency medical service arrival. Prehospital cardiopulmonary resuscitation duration was defined as the time from emergency medical service-initiated cardiopulmonary resuscitation to prehospital return of spontaneous circulation or to hospital arrival. The primary outcome was one-month survival with favourable neurological outcome (cerebral performance category 1 or 2). The association between prehospital cardiopulmonary resuscitation duration and favourable neurological outcome was assessed using univariable and multivariable logistic regression analyses. RESULTS: The proportion of favourable neurological outcomes was 2.3% in total, 7.6% in public locations, 1.5% in residential locations and 0.7% in nursing homes (P < 0.001). In univariable and multivariable logistic regression analyses, longer prehospital cardiopulmonary resuscitation duration was associated with poor neurological outcome, regardless of arrest location (P for trend < 0.001). Patients with shockable rhythm in both public and residential locations had better neurological outcome than those in nursing homes at any time point, and residential and public locations had a similar neurological outcome tendency among patients with shockable rhythm. CONCLUSIONS: Longer prehospital cardiopulmonary resuscitation duration was independently associated with a lower proportion of patients with favourable neurological outcomes. Moreover, the association between prehospital cardiopulmonary resuscitation duration and neurological outcome differed according to the location of arrest and the first documented rhythm.

BACKGROUND: Female out-of-hospital cardiac arrest (OHCA) patients have been reported to be less likely to receive cardiopulmonary resuscitation by bystanders compared with male patients in prehospital settings. However, no clinical studies have investigated gender disparities in the application of public-access automated external defibrillator (AED) pads among OHCA patients in public locations. METHODS: OHCA data from 2011 to 2018 were obtained from the OHCA registry in Osaka City, Japan and OHCAs that occurred in public locations were included. Gender differences in receiving public-access AED pad application by bystanders were assessed according to the age of the OHCA patient (<15, 15-49, 50-74, and ≥75 years) after controlling confounders. RESULTS: The analysis included 4358 OHCA patients (3313 male and 1045 female patients). The multivariable logistic regression analyses found no significant gender differences in the likelihood of public-access AED pad application among patients aged <15 years (5.3% in male patients vs 6.3% in female patients; adjusted ORâ¯=â¯1.00, pâ¯=â¯1.000), 50-74 years (16.8% vs 12.7%; adjusted ORâ¯=â¯0.96, pâ¯=â¯0.796), and ≥75 years (12.3% vs 14.8%; adjusted ORâ¯=â¯1.45, pâ¯=â¯0.098). In contrast, among patients aged 15-49 years, female patients were significantly less likely to receive public-access AED pad application compared with male patients (12.1% vs 5.2%; adjusted ORâ¯=â¯0.54, pâ¯=â¯0.032). CONCLUSION: In this population, female OHCA patients of reproductive age (15-49 years) were less likely to receive public-access AED pad application compared with male patients of the same age group.

The impact of time of day or day of week on the survival of emergency trauma patients is still controversial. The purpose of this study was to evaluate the outcomes of these patients according to time of day or day of week of emergency admission by using data from the nationwide Japan Trauma Data Bank (JTDB).This study enrolled 236,698 patients registered in the JTDB database from 2004 to 2015, and defined daytime as 09:00 AM to 16:59 PM and nighttime as 17:00 PM to 08:59 AM, weekdays as Monday to Friday, and weekends as Saturday, Sunday, and national holidays. The outcome measures were death in the emergency room (ER) and discharge to death.In total, 170,622 patients were eligible for our analysis. In a multivariable logistic regression adjusted for confounding factors, both death in the ER and death at hospital discharge were significantly lower during the daytime than at nighttime (623/76,162 [0.82%] vs 954/94,460 [1.01%]; adjusted odds ratio [AOR] 0.79; 95% confidence interval [CI] 0.71-0.88 and 5765/76,162 [7.57%] vs 7270/94,460 [7.70%]; AOR 0.88; 95% CI 0.85-0.92). In contrast, the weekdays/weekends was not significantly related to either death in the ER (1058/114,357 [0.93%] vs 519/56,265 [0.92%]; AOR 0.95; 95% CI 0.85-1.06) or death at hospital discharge (8975/114,357 [7.85%] vs 4060/56,265 [7.22%]; AOR 1.02; 95% CI 0.97-1.06).In this population of emergency trauma patients in Japan, both death in the ER and death at hospital discharge were significantly lower during the daytime than at night, but the weekdays/weekends was not associated with outcomes of these patients.

BACKGROUND: The use of public-access automated external defibrillators (AEDs) has become common in Japan. To provide a strategy for appropriate public-access AED deployment, we assessed public-access defibrillation (PAD) by laypersons and the outcomes following out-of-hospital cardiac arrest (OHCA) among adult patients by location of arrest. METHODS: From a nationwide, prospective, population-based registry of patients after OHCA in Japan, we enrolled adult patients with bystander-witnessed OHCA of medical origin in public locations between 2013 and 2015. The primary outcome measure was one-month favorable neurological outcome defined by cerebral performance category 1 or 2. Factors associated with favorable neurological outcome after ventricular fibrillation (VF) were assessed by multivariable logistic regression analysis. RESULTS: A total of 20,970 adult bystander-witnessed OHCAs of medical origin occurred in public locations. Of those, the proportions of PAD by location were: 13.1% (757/5761) in public areas, 15.9% (333/2089) at workplaces, 26.0% (544/2095) in recreation/sports areas, 36.1% (112/310) in educational institutions, and 5.8% (241/4151) on streets/highways. In a multivariable analysis of VF arrests, both bystander cardiopulmonary resuscitation [adjusted odds ratio (AOR), 1.78; 95% confidence interval (CI), 1.54-2.07] and PAD (AOR, 2.33; 95% CI, 2.05-2.66), and emergency medical service (EMS) response time (AOR, 0.89; 95% CI, 0.87-0.90) were associated with improved outcomes. Earlier PAD initiated by bystanders before EMS arrival was also associated with better outcomes after OHCA. CONCLUSIONS: In Japan, where public-access AEDs are well-disseminated, the PAD program worked effectively for adult OHCA of medical origin occurring in public locations. Notably, the proportions of PAD differed substantially according to specific public locations.
