BACKGROUND: It is reported that abnormal eating behavior is more frequent in the group of weight control than those of no control. Repeated and chronic binge eating behavior has associations with impaired work and social functioning, overconcerns with body shape and weight. The purpose of this study is to investigate the degree of abnormal eating behavior according to weight management, depression level and obesity. METHODS: From June 1999 to July 1999, we collected self record questionnaire including body mass index(BMI), Beck Depression Inventory(BDI), Eating Attitude Test(EAT) from 1292 students of one girl's high school in Seoul. Study subjects were divided by BMI, the set point was 25 kg/m2. EAT score associated with weight control, BMI, BDI, smoking and alcohol was assessed by multiple linear regression. Study subjects were also grouped by the existence of the history of weight management behavoir, then BMI, EAT score and BDI in each subgroups was assessed by t test. RESULTS: Obese students were 42, whereas those of BMI under 25 kg/m2 were 1191. BDI score ranging from 5 to 20 were 940, 21 to 63 were 179. The EAT score has significant relevance to the history of weight control, BMI, and BDI score in order. The EAT score and BMI were higher in the subjects who experienced various modes of weight control (48.41+/-14.47 vs 33.63+/-12.52 in EAT, 20.34+/-2.26 vs 18.72+/-1.89)(p<0.01). CONCLUSION: EAT score was associated with weight control, BMI and BDI. EAT score and BMI were higher in weight control samples.

BACKGROUND: An automatic alarm system was developed was developed for unexpected vital sign instability in admitted patients to reduce staffing needs and costs related to rapid response teams. This was a pilot study of the automatic alarm system, the medical emergency system (MES), and the aim of this study was to determine the effectiveness of the MES before expanding this system to all departments. METHODS: This retrospective, observational study compared the performance of patients admitted to the pulmonary department at a single center using patient data from three 3-month periods (before implementation of the MES, December 2013–February 2014; after implementation of the MES, December 2014–February 2015 and December 2015–February 2016). RESULTS: A total of 571 patients were admitted to the pulmonary department during the three observation periods. During this pilot study, the MES automatically issued 568 alarms for 415 admitted patients. There was no significant difference in the rate of cardiopulmonary resuscitation (CPR) before and after application of the MES. The mortality rate also did not change. However, it appeared that CPR was prevented in four patients admitted from the general ward to the intensive care unit (ICU) during MES implementation. The median length of hospital stay and median length of ICU stay were not significantly different before and after MES implementation. CONCLUSIONS: Although we did not find a significant improvement in outcomes upon MES implementation, the CPR rate and mortality rate did not increase despite increased comorbidities. This was a small pilot study and, based on these results, we believe that the MES may have significant effects in longer-term and larger-scale studies.

Purpose: This study aimed to investigate the nationwide intention to delegate clinical practice of medical specialists in accordance with the enactment of the scope of practice for advanced practice nurses (APNs). Methods: Data were collected from October to December 2021 using Google Surveys. In total, 147 medical specialists from 12 provinces responded to the survey. The survey questionnaire was categorized into four legislative draft duties, according to the scope of practice (a total of 41 tasks): Twenty-nine tasks on treatments, injects, etc., performed under the guidance of a physician and other activities necessary for medical treatment (treatment domain); two tasks on collaboration and coordination; six tasks on education, counseling, and quality improvement; four regarding other necessary tasks. Participants were asked whether they were willing to delegate the tasks to APN. Results: The intention to delegate tasks to APN was higher for non-invasive tasks such as blood sampling (97.3%) or simple dressing (96.6%). Invasive tasks such as endotracheal tube insertion (10.2%), sampling: bone marrow biopsy & aspiration (23.8%) showed low intention to delegate in the treatment domain. Participants who were older, male, and had more work careers with APN, showed a higher intention to delegate tasks. Conclusion To prevent confusion in the clinical setting, a clear agreement on the scope of APN practice as APN delegated by physicians should be established. Based on this study, legal practices that APN can perform legally should be established.

Purpose: : The purpose of this study was to understand and describe the experiences of the advanced nurse practitioner (APN) system used by healthcare providers including APNs, doctors who worked with APNs, and APN master’s course professors at a graduate school. Methods: : Qualitative data were collected via snowball sampling. The participants were nine APNs, six doctors, and three professors. They were divided into three focus groups, each of which consisted of all three types of healthcare providers. Data were collected via interviews with the three focus groups conducted from September to October 2019. All interviews were audiotaped and transcribed verbatim. The transcribed data then underwent qualitative content analysis. Results: : Based on the data, we extracted four themes and 14 categories. The themes were “Role and system of APNs started according to healthcare environment changes”, “Optimal healthcare provider to ensure quality of care”, “Confused role and system of APNs due to incomplete medical law”, and “Tasks for the stable operation of the APN system.” Conclusion : For quality treatment and safety of patients, a legal basis must be established for the APN system. For its stable operation, social consensus regarding legislation about APNs’ scope of practice is required. Finally, a discussion is necessary about the integration of APNs’ 13 fields.

The brain is the highly organized organ which attributes to consciousness, memory and language. Approximately 85ml of oxygenated blood from the heart is delivered to the brain each minute. In human beings, a steady cerebral blood flow is maintained which cerebral structures are perfused roughly in proportion to their metabolic demands which are actively depend on function. Therefore, cerebral function is the most important physiologic regulator of cerebral blood flow. The measurement of cerebral blood flow is a very important toolin exploring the function of the human brain in healthand disease. An impairment of normal cerebral blood flow indicates clinical derangement of central neruous system. Besides the clinical sympatoms, cerebral blood flow investigation has become our main guideline for judging the timing of operation and prognosis of disease as well as evaluation of treatment. The determination of normal cerebral blood flow in Korean seemed to be enormously important for further study on this subject. For the purpose of establishing normal value of cerebral blood flow in Korean, the author have studied 93 healthy persons with 133Xe-inhalation method using Obrist's two compartmental analysis. Followings were the results. 1) Normal values of FI, ISI, and WIin children below the age of 9 were 113.5+/-36.9, 62.5+/-13.0 and 55.6+/-6.4 each. 2) Normal values of FI, ISI, and WI in the group above the age of 9 were 75.5+/-15.5, 44.6+/-5.7 and 43.1+/-3.95 each. 3) There was no significant difference between mean values of right and left side hemisphere. 4) There was significant decrease in r-CBF in the group above the age of 9, but the decrement by age since after the age of 9 was not significant statistically. 5) The difference of mean values among each lobe was not significant statistically.

Background/Aims: Intensive care unit (ICU) quality is largely determined by the mortality rate. Therefore, we aimed to develop and validate a novel prognostic model for predicting mortality in Korean ICUs, using national insurance claims data. Methods: Data were obtained from the health insurance claims database maintained by the Health Insurance Review and Assessment Service of South Korea. From patients who underwent the third ICU adequacy evaluation, 42,489 cases were enrolled and randomly divided into the derivation and validation cohorts. Using the models derived from the derivation cohort, we analyzed whether they accurately predicted death in the validation cohort. The models were verified using data from one general and two tertiary hospitals. Results: Two severity correction models were created from the derivation cohort data, by applying variables selected through statistical analysis, through clinical consensus, and from performing multiple logistic regression analysis. Model 1 included six categorical variables (age, sex, Charlson comorbidity index, ventilator use, hemodialysis or continuous renal replacement therapy, and vasopressor use). Model 2 additionally included presence/absence of ICU specialists and nursing grades. In external validation, the performance of models 1 and 2 for predicting in-hospital and ICU mortality was not inferior to that of pre-existing scoring systems. Conclusions The novel and simple models could predict in-hospital and ICU mortality and were not inferior compared to the pre-existing scoring systems.

PURPOSE: This study aimed to propose a common scope of practice (SOP) for 13 specialties of Advanced Practice Nurses (APNs) in Korea.METHODS: The first draft of a common SOP was extracted from domestic and international laws with a literature review by 17 experts from the Korean Association of Advanced Practice Nurses (KAAPN). Then, the common SOP was finalized after comparing the activities of APNs in clinical settings.RESULTS: A total of 70 duties were identified and six categories were suggested for the common SOP. The SOP proposed by the KAAPN featured the following: 1) identification of and discrimination between health problems; 2) prescription and implementation of diagnostic tests; 3) treatment of injuries and diseases while implementing measures to prevent exacerbation; 4) prescription of medicinal products in line with 1) to 3); 5) referral and consultation; and 6) education and counseling. It was then confirmed that the proposed six categories in the common SOP reflected all the duties performed by APNs in clinical practice, including all 40 activities.CONCLUSION: The results of this study can be used as evidence for the legalization of a common SOP for APNs. Given the increasing multidisciplinary team approach adopted in Korean hospitals, it may be desirable to establish a broader SOP to reflect the diverse duties of APNs.

Background: The treatment success rate for tuberculosis (TB) has stagnated at 80–81% in South Korea, indicating unsatisfactory outcomes. Enhancing treatment success rate necessitates the development of individualized treatment approaches for each patient. This study aimed to identify the risk factors associated with unfavorable treatment outcomes to facilitate tailored TB care. Methods: We retrospectively analyzed the data of patients with active TB between January 2019 and December 2020 at a single tertiary referral center. We classified unfavorable treatment outcomes according to the 2021 World Health Organization guidelines as follows:“lost to follow-up” (LTFU), “not evaluated” (NE), “death,” and “treatment failure” (TF).Moreover, we analyzed risk factors for each unfavorable outcome using Cox proportional hazard regression analysis. Results: A total of 659 patients (median age 62 years; male 54.3%) were included in the study.The total unfavorable outcomes were 28.1%: 4.6% LTFU, 9.6% NE, 9.1% deaths, and 4.9% TF. Multivariate analysis showed that a culture-confirmed diagnosis of TB was associated with a lower risk of LTFU (adjusted hazard ratio [aHR], 0.25; 95% confidence interval [CI], 0.10–0.63), whereas the occurrence of adverse drug reactions (ADRs) significantly increased the risk of LTFU (aHR, 6.63; 95% CI, 2.63–16.69). Patients living far from the hospital (aHR, 4.47; 95% CI, 2.50–7.97) and those with chronic kidney disease (aHR, 3.21; 95% CI, 1.33–7.75) were at higher risk of being transferred out to other health institutions (NE). Higher mortality was associated with older age (aHR, 1.06; 95% CI, 1.04–1.09) and comorbidities. The ADRs that occurred during TB treatment were a risk factor for TF (aHR, 6.88; 95% CI, 2.24–21.13). Conclusion Unfavorable outcomes of patients with TB were substantial at a tertiary referral center, and the risk factors for each unfavorable outcome varied. To improve treatment outcomes, close monitoring and the provision of tailored care for patients with TB are necessary.

OBJECTIVES: This cross-sectional study was performed to examine if the serum gamma-glutamyltransferase (GGT) level that is within its normal range is associated with the risk of type 2 diabetes and if the association between the waist hip ratio (WHR) and type 2 diabetes is different depending on the serum GGT levels. METHODS: The study subjects were 23,436 persons aged 40 years or older and who participated in regular health check-ups at 11 hospitals (males: 5,821, females: 17,615). The gender-specific quintiles of the serum GGT and WHR were used to examine the associations with type 2 diabetes. RESULTS: The serum GGT levels within their normal range were positively associated with type 2 diabetes only in women. The adjusted odds ratios (ORs) were 1.0, 1.0, 1.4, 2.1, and 2.5 according to the quintiles of the serum GGT (p(trend)<0.01). The WHR was more strongly associated with the prevalence of diabetes among the women with a high-normal serum GGT level as compared with those with a low-normal serum GGT level (p for interaction=0.02). For example, the adjusted ORs for women with a low normal serum GGT level were 1.0, 1.2, 1.5, 2.2, and 2.4 according to the quintiles of the WHR, while those figures were 1.0, 2.4, 3.6, 5.0, and 8.3 among the women with a high normal serum GGT level. However, in men, the serum GGT was very weakly associated with type 2 diabetes and the association between the WHR and type 2 diabetes was not different depending on the serum GGT level. CONCLUSIONS: Serum GGT within its normal range was positively associated with type 2 diabetes, and central obesity was more strongly associated with the prevalence of type 2 diabetes when the serum GGT level was high-normal. However, these associations were observed only in women, which is different from the previous findings. The stronger relation between central obesity and type 2 diabetes among women with a high-normal serum GGT level can be useful for selecting a group that is at high risk for type 2 diabetes irregardless of whatever the underlying mechanism is.
