Epidemiological and Survival Trends of Pediatric Cardiac Arrests in Emergency Departments in Korea: A Cross-sectional,Nationwide Report

Cardiac arrest (CA) in children is associated with high mortality rates. In Korea, cohort studies regarding the outcomes of pediatric CAs are lacking, especially in emergency departments (EDs) or in-hospital settings. This study was conducted to examine the trends in epidemiology and survival outcomes in children with resuscitation-attempted CAs using data from a cross-sectional, national, ED-based clinical registry. We extracted cases in which cardiopulmonary resuscitation and/or manual defibrillation were performed according to treatment codes using the National Emergency Department Information System (NEDIS) from 2008 to 2012. The total number of ED visits registered in the NEDIS during the 5-yr evaluation period was 20,424,530; among these, there were 2,970 resuscitation-attempted CAs in children. The annual rates of pediatric CAs per 1,000 ED visits showed an upward trend from 2.81 in 2009 to 3.62 in 2012 (P for trend = 0.045). The median number of estimated pediatric CAs at each ED was 7.8 (25th to 75th percentile, 4 to 13) per year. The overall rates for admission survival and discharge survival were 35.2% and 12.8%, respectively. The survival outcome of adults increased substantially over the past 5 yr (11.8% in 2008, 11.7% in 2010, and 13.6% in 2012; P for trend = 0.001); however, the results for children did not improve (13.6% in 2008, 11.4% in 2010, and 13.7% in 2012; P for trend = 0.870). Conclusively, we found that the overall incidence of pediatric CAs in EDs increased substantially over the past 5 yr, but without significantly higher survival outcomes.

Associations of visit-to-visit fasting glucose with risk of mortality: A retrospective cohort study of 48,077 people with type 2 diabetes

AimTo investigate the association between mean fasting glucose (FG) and variability in visit-to-visit FG and risk of mortality in people with type 2 diabetes (T2D).MethodsThis retrospective cohort study included 48,077 Chinese men and women with T2D. The yearly mean and coefficient of variation for fasting glucose (mean-FG and FG-CV, respectively) were based on at least two measurements taken each year over a mean duration of 4.5 years. Deaths and their causes were identified using the Shanghai Vital Statistics registry. Mean-FG and FG-CV served as time-dependent variables in Cox models to estimate their associations with risk of mortality; hazard ratios (HRs) were adjusted for baseline risk factors. Potential non-linear associations were examined by restricted cubic splines.ResultsDuring an average 4.5 years of follow-up, 2095 men and 1923 women died. Men with low mean-FG and women with low or high FG were at greater risk of death. Mean-FG was not associated with either cardiovascular disease (CVD) or cancer-specific mortality, whereas higher yearly FG-CV was associated with all-cause and CVD-/cancer-specific mortality in both genders. Compared with a yearly FG-CV of 1.76 (5th percentile), men and women with an FG-CV of 14.14 (75th percentile) had HRs (95% CI) of 1.41 (1.24–1.61) and 1.44 (1.26–1.65), respectively, for all-cause mortality.ConclusionVariability of visit-to-visit FG may be a more sensitive predictor of risk of death than mean-FG in people with T2D.     

Five-year mortality trends associated with chronic pancreatitis in South Korea: A population based cohort study

BackgroundChronic pancreatitis (CP) is associated with all-cause and cancer-related mortality; however, the risk of mortality associated with alcoholic and non-alcoholic CP remains controversial. This study investigated whether CP increased the risk of 5-year all-cause and cancer-specific mortality compared to a control population.MethodsThis population-based study used data from a sample cohort of the National Health Insurance Service (NHIS) database in South Korea. CP was defined as disease code K86.0 (alcohol-induced CP) and K86.1 (other CP and non-alcoholic CP) from the tenth edition of the International Classification of Diseases.ResultsThe prevalence of chronic alcoholic pancreatitis increased from 0.01% in 2002 to 0.07% in 2015, and the prevalence of chronic non-alcoholic pancreatitis increased from 0.08% in 2002 to 0.50% in 2015. In the 2010 NHIS cohort (n = 826,909), CP was associated with an increased risk of 5-year all-cause mortality (hazard ratio [HR] = 1.25, 95% confidence interval [CI]: 1.25 to 1.66, P < 0.001). Additionally, non-alcoholic CP was associated with an increased risk of 5-year all-cause mortality (HR = 1.47, 95% CI: 1.27 to 1.71, P < 0.001); in contrast, alcohol-induced CP was not significantly associated with mortality risk (P = 0.569). Similar tendencies were observed for the 5-year cancer-related mortality risk.ConclusionsIn South Korea, the prevalence of alcoholic and non-alcoholic CP increased during 2002–2015. CP may be an independent risk factor for 5-year all-cause and cancer-related mortality. In this study, this association was more evident in patients with non-alcoholic CP.     

感染HIV的孕产妇预防艾滋病母婴传播服务需求与障碍分析

目的了解艾滋病病毒(HIV)感染孕产妇的预防艾滋病母婴传播服务需求与服务利用障碍。方法对某艾滋病高发地区,自2003年以来截至2004年10月发现并分娩的HIV感染孕产妇进行问卷调查。结果13.79%的孕产妇不愿意接受产前检查,5.17%的孕产妇不愿意住院分娩,怕歧视、担心检查和住院分娩费用高等是孕产妇不接受孕产期保健的主要原因;96.43%的孕产妇愿意本人和给孩子服用抗逆转录病毒药物预防艾滋病母婴传播,但只有87.50%的孕产妇服用了抗HIV药物,未服药的原因为临产急诊分娩,未得到检测结果,延误了孕产妇和婴儿的服药时机;89.29%的孕产妇希望其所生婴幼儿获得随访服务,但只有58.93%的婴幼儿得到过随访服务,其中51.52%的婴幼儿在出生后3个月内得到首次随访;怕别人知道自己的感染情况是不愿意接受随访的主要原因;近7%的孕产妇不愿意或不知道要给所生的婴幼儿进行HIV抗体检测。结论育龄妇女和孕产妇艾滋病检测不及时、非住院分娩、婴幼儿随访服务薄弱、经济负担、社会歧视等问题,是预防艾滋病母婴传播服务利用的主要障碍,预防艾滋病母婴传播综合能力亟待加强。     

Concept analysis: Role ambiguity in senior nursing students

Role ambiguity is a lack of clarity or uncertainty related to one's position or role. Role ambiguity has been documented in the literature in relationship to athletics, industry, business, education, and nursing. However, a concept analysis has not been performed. Therefore, the process of concept analysis outlined by Walker and Avant is now used to look at the concept of role ambiguity and its relevance to senior nursing students’ socialization and education into the profession of nursing. Attributes, antecedents, consequences, and empiric referents are discussed and theories commonly associated with role ambiguity are presented. At the end of the analysis, an operational definition is provided for use in exploring the concept of role ambiguity as it relates to senior nursing students’ articulation of the role of the professional nurse.     

Conceptualizing collaboration in nursing

Nurses practicing at every level need a clear definition of collaboration before applying the concept in daily practice. Additionally, a conceptual definition of collaboration in nursing assists nurse researchers in finding or developing instruments for measuring collaboration and attributes of collaboration, which will enhance research findings. Collaboration extends beyond communication and includes sharing, teamwork, and respect. Multiple databases including CINAHL, PubMed, and ERIC were searched using the keywords collaboration, nursing, concept analysis, sharing, respect, and teamwork. For this analysis, using Walker and Avant’s method, the conceptual definition of collaboration in nursing is an intraprofessional or interprofessional process by which nurses come together and form a team to solve a patient care or healthcare system problem with members of the team respectfully sharing knowledge and resources. Two instruments consistent with the conceptual definition of collaboration are The Mayo High Performance Teamwork Scale (MHPTS) and Team Strategies and Tools to Enhance Performance and Patient Safety (Team STEPPS) and these instruments are summarized in this study. Finally, case scenarios are given to illustrate exemplars of collaboration in clinical practice.
