Purpose: The "golden hour" concept in trauma is pervasive despite little evidence to support it. This study addressed the association between prehospital time and in-hospital mortality in seriously injured abdominal trauma victims. Methods: A retrospective study was conducted over a three-year period from 2006 to 2008. We analyzed trauma victims with abdominal injuries who underwent an emergency laparotomy in a local emergency center located in a city with a population of 2,500,000. According to the 'golden hour' oncept, we separated the trauma victims into two groups (Gourp 1: prehospital time ${\leq}$ 1 hour, Group 2: prehospital time > 1hour) and investigated several factors, such as time, process, and outcome. Results: During the period from January 2006 to December 2008 139 trauma victims underwent an emergency laparotomy, and 89 of them were enrolled in this study. Between the two groups, emergency department (ED) access, transportation, and injury mechanism showed statistically meaningful differences, but no statistically meaningful differences were observed in various measures of the outcome, such as length of hospital stay, length of Intensive Care Unit stay, and mortality. In a univariate logistic regression study, age (odds ratio [OR]: 1.101; 95% confidence interval [CI]: 1.026 to 1.182), Revised Trauma Score (RTS) (OR: 0.444; 95% CI 0.278 to 0.710), hemoglobin (OR: 0.749; 95% CI: 0.585 to 0.960), and creatinine (OR: 24.584; 95% CI: 2.019 to 299.364) were significant prognostic factors, but prehospital time was not. In a multivariate logistic regression study, age and RTS were significant associated with mortality. Conclusion: In this study, we found no association between prehospital time and mortality among abdominal trauma patient who underwent an emergency laparotomy. We suggest that in our current out-of-hospital and emergency care system, until arrival at the hospital time may be less crucial for trauma victims than once thought.

Background: The purpose of this study is to identify the factors infecting the medical care utilization from a new perspective by newly classifying the categories of administrative districts using the urban decline index and medical vulnerability index as indicators. Methods: This study targeted 150,940 people who used medical services using the 2015 cohort database (DB), 2010-2015 urban regeneration analysis index DB, and 2014-2015 public health and medical statistics DB. The decline of the region was classified using the urban decline index typed using k-means clustering and the medical vulnerability index typed using the quantile score calculation. Regression analysis was performed 3 times with medical expenditure, length of stay, and the number of outpatient visits as dependent variables. Results: There were 37 stable region (47.4%), 29 health vulnerable region (37.2%), and 12 decline region (15.4%). The health vulnerable region had lower medical expenditure, fewer outpatient visits, and a higher length of stay than the stable region. The decline region was all higher than the stable region but had no significant effect. Conclusion: The factors that cause the health disparity between regions are not only factors related to individual health behavior but also environmental factors of the local community. Therefore, there is a need for a systematic alternative that properly considers the resources within the community and reflects the characteristics of the population.

Purpose: Sports offer several health benefits but are not free of injury risk. Activity dynamics vary across sports, impacting the injury profile and thereby influencing healthcare resource utilization and health outcomes. The purpose of this study was to investigate sports-related major trauma cases and compare differences across sports and activity groups. Methods: A retrospective case notes review of sports-related major traumas over a 5-year period was conducted. Demographic, hospital episode-related, and health outcome-related data were analyzed, and differences were compared across sports and activity groups. The Glasgow Outcome Scale (GOS) at discharge was used as the primary outcome measure and the length of hospital stay as the secondary outcome measure. Results: In total, 76% of cases had good recovery at discharge (GOS, 5), 19% had moderate disability (GOS, 4), and 5% had severe disability (GOS, 3). The mean length of hospital stay was 11.2 days (range, 1-121 days). The most severely injured body region was the limbs (29.1%) and vertebral/spinal injuries were most common (33%) in terms of location. A significant difference (P<0.05) existed in GOS across sports groups, with motor sports having the lowest GOS. However, no significant differences (P>0.05) were found in other health-outcome variables or injury patterns across sports or activity groups, although more competitive sports cases (67%) required admission than recreational sports cases (33%). Conclusions: Spinal injuries are the most frequent sports injuries, bear the worst health outcomes, and warrant better preventive measures. Head injuries previously dominated the worst outcomes; this change is likely due to better preventive and management modalities. Competitive sports had a higher injury frequency than recreational sports, but no difference in health outcomes or injury patterns.

Purpose: The purpose was to investigate nurse staffing levels and patient outcomes(nosocomial infection, patient fall, pressure ulcer). Method: The subjects of this study were 305 nurses from 20 general hospitals who worked at 39 medical and surgical wards. Self-reporting questionnaire which was developed by the writer through preceding study was used. In data analysis, SPSS WIN 10.0. program was utilized for descriptive statistics, ANOVA. Result: The mean of patient-to-nurse ration was 5.2:1. 65% among 20 hospitals was over 300 beds, 90 was located in urban area and 55 was private hospitals. Patient-to-nurse ration of hospitals in under 300 beds or rural area or private ownership was lower than hospitals in 300 beds or urban area or public ownership. 89.9 among 39 wards was medical or surgical wards. The mean of length of stay, 8-14 days got a majority and showed higher patient-to-nurse ration. Of the general characteristics, rural was significantly hight to patient fall(F=3.205, p<.05), medical unit was significantly high to patient fall, pressure ulcer(patient fall: F=8.890, p<.001, pressure ulcer: F=3.399, p<.05) and over 15 days was significantly higher than under 14 days of the mean of length of stay. And there was significant relationship between over 6.0:1 and over 4.0:1 to less than 5.0:1(F=4.817,p<.01). Conclusion: This study has shown a relationship between patient-to-nurse ration and patient fall using not objective research tool but self-reporting questionnaire. Therefore further research is needed to study using objective research tool. Based on this study, the effect of nurse staffing levels on patient outcome also has to be studied.

Background: Various truncal block techniques with ultrasonography (USG) are becoming widespread to reduce postoperative pain and opioid requirements in video-assisted thoracoscopic surgery (VATS). The primary aim of our study was to determine whether the USG-guided serratus anterior plane block (SAPB) is as effective as the thoracic paravertebral block (TPVB) in VATS. Our secondary aim was to evaluate patient and surgeon satisfaction, block application time, first analgesic time, and length of hospital stay. Methods: Patients in Group SAPB received 0.4 mL/kg bupivacaine with a USG-guided SAPB, and patients in Group TPVB received 0.4 mL/kg bupivacaine with a USG-guided TPVB. We recorded the pain scores, the timing of the first analgesic requirement, the amount of tramadol consumption, and postoperative complications for 24 hours. We also recorded the block application time and length of hospital stay. Results: A total of 62 patients, with 31 in each group (Group SAPB and Group TPVB) completed the study. Between the two groups, there were no significant differences in rest and dynamic pain visual analog scale scores at 0, 1, 6, 12, and 24 hours after surgery. The total consumption of tramadol was significantly lower in the TPVB group (P = 0.026). The block application time was significantly shorter in Group SAPB (P < 0.001). Conclusions: An SAPB that is applied safely and rapidly as a part of multimodal analgesia in patients who undergo VATS is not inferior to the TPVB and can be an alternative to it.

Purpose : This study aimed to assess the effectiveness of an advanced practice nurse (APN)-driven ventilator weaning protocol for patients undergoing cardiac surgeries. Methods : A retrospective analysis was conducted on 226 patients admitted to the intensive care unit (ICU) of a tertiary hospital between January and June 2020, following a cardiac surgery. Patients were divided into an APN protocol-applied group (experimental group, n=152) and a control group managed based on doctors' judgment (n=74). Ventilator weaning criteria and clinical outcomes, including duration of ventilation, length of ICU stay, and rate of reintubation, were compared between the two groups. Results : Patients in the control group were older and had a higher incidence of massive bleeding from chest tube drainage (>100 cc/hr) at baseline. The average duration of ventilation was significantly shorter in the experimental group compared to the control group (7.44 vs. 21.61 hours, p <.001). Furthermore, the mean length of ICU stay was shorter in the experimental group compared to the control group (47.96 vs. 77.97 hours, p <.001). There was no difference in the rate of reintubation between the two groups. Conclusion : These findings suggest that an APN-driven ventilator weaning protocol can improve clinical outcomes without significant complications. These results support the adoption of APN-driven mechanical ventilator weaning protocols in clinical practice.

Background: This study investigates association modified category medical specialization (CMS) and hospital charge, length of stay (LOS), and mortality among lumbar spine disease inpatients. Methods: This study used National Health Insurance Service-cohort sample database from 2002 to 2013, using stratified representative sampling released by the National Health Insurance Service. A total of 56,622 samples were analyzed. The primary analysis was based on generalized estimating equation model accounting for correlation among individuals within each hospital. Results: Inpatients admitted with lumbar spine disease at hospitals with higher modified CMS had a shorter LOS (estimate, -1.700; 95% confidence interval [CI], -1.886 to -1.514; p<0.0001). Inpatients admitted with lumbar spine disease at hospitals with higher modified CMS had a lower mortality rate (odds ratio, 0.635; 95% CI, 0.521 to 0.775; p<0.0001). Inpatients admitted with lumbar spine disease at hospitals with higher modified CMS had higher hospital cost per case (estimate, 192,658 Korean won; 95% CI, 125,701 to 259,614; p<0.0001). However, inpatients admitted with lumbar spine surgery patients at hospitals with higher modified CMS had lower hospital cost per case (estimate, -152,060 Korean won; 95% CI, -287,236 to -16,884; p=0.028). Inpatients admitted with lumbar spine disease at hospitals with higher modified CMS had higher hospital cost per diem (estimate, 55,694 Korean won; 95% CI, 46,205 to 65,183; p<0.0001). Conclusion: Our results showed that increase in hospital specialization had a substantial effect on decrease in hospital cost per case, LOS, and mortality, and on increase in hospital cost per diem among lumbar spine disease surgery patients.
