Abstract PDF: Background
In patients with out-of-hospital cardiac arrest (OHCA), guidelines recommend advanced airway (AA) management at the advanced cardiovascular life support stage; however, the ideal timing remains controversial. Therefore, we evaluated the prognosis according to the timing of AA in patients with OHCA.
Methods
We conducted a retrospective observational study of patients with OHCA at six major hospitals in Daegu Metropolitan City, South Korea, from August 2019 to June 2022. We compared groups with early and late AA and evaluated prognosis, including recovery of spontaneous circulation (ROSC), survival to discharge, and neurological evaluation, according to AA timing.
Results
Of 2,087 patients with OHCA, 945 underwent early AA management and 1,142 underwent late AA management. The timing of AA management did not influence ROSC in the emergency department (5–6 minutes: adjusted odds ratio [aOR], 0.97; p=0.914; 7–9 minutes: aOR, 1.37; p=0.223; ≥10 minutes: aOR, 1.32; p=0.345). The timing of AA management also did not influence survival to discharge (5–6 minutes: aOR, 0.79; p=0.680; 7–9 minutes: aOR, 1.04; p=0.944; ≥10 minutes: aOR, 1.86; p=0.320) or good neurological outcomes (5–6 minutes: aOR, 1.72; p=0.512; 7–9 minutes: aOR, 0.48; p=0.471; ≥10 minutes: aOR, 0.96; p=0.892).
Conclusion
AA timing in patients with OHCA was not associated with ROSC, survival to hospital discharge, or neurological outcomes.

Background
Recently, there have been various developments in medical service robots (MSRs). However, few studies have examined the perceptions of those who use it. The purpose of this study is to identify user perceptions of MSRs.
Methods
We conducted a survey of 320 patients, doctors, and nurses. The contents of the survey were organized as follows: external appearances, perceptions, expected utilization, possible safety accidents, and awareness of their responsibilities. Statistical analyses were performed using t-test, chi-square test, and analysis of variance.
Results
The most preferred appearance was the animal type, with a screen. The overall average score of positive questions was 3.64±0.98 of 5 points and that of negative questions was 3.24±0.99. Thus, the results revealed that the participants had positive perceptions of MSR. The overall average of all expected utilization was 4.05±0.84. The most expected utilization was to guide hospital facilities. The most worrisome accident was exposure to personal information. Moreover, participants thought that the overall responsibility of the robot user (hospital) was greater than that of the robot manufacturer in the case of safety accidents.
Conclusion
The perceptions of MSRs used in hospital wards were positive, and the overall expected utilization was high. It is necessary to recognize safety accidents for such robots, and sufficient attention is required when developing and manufacturing robots.

Abstract PDF

Background
To prepare for future work stoppages in the medical industry, this study aimed to identify the effects of healthcare worker strikes on the mortality rate of patients visiting the emergency department (ED) at six training hospitals in Daegu, Korea.
Methods
We used a retrospective, cross-sectional, multicenter design to analyze the medical records of patients who visited six training hospitals in Daegu (August 21–September 8, 2020). For comparison, control period 1 was set as the same period in the previous year (August 21–September 8, 2019) and control period 2 was set as July 1–19, 2020. Patient characteristics including age, sex, and time of ED visit were investigated along with mode of arrival, length of ED stay, and in-hospital mortality. The experimental and control groups were compared using t-tests, and Mann-Whitney U-test, chi-square test, and Fisher exact tests, as appropriate. Univariate logistic regression was performed to identify significant factors, followed by multivariate logistic regression analysis.
Results
During the study period, 31,357 patients visited the ED, of which 7,749 belonged to the experimental group. Control periods 1 and 2 included 13,100 and 10,243 patients, respectively. No significant in-hospital mortality differences were found between study periods; however, the results showed statistically significant differences in the length of ED stay.
Conclusion
The ED resident strike did not influence the mortality rate of patients who visited the EDs of six training hospitals in Daegu. Furthermore, the number of patients admitted and the length of ED stay decreased during the strike period.

Abstract PDF

BACKGROUND
The aim of this study was to confirm the risk factors for low back pain and injury to improve the prevention and treatment of lower back pain. MATERIALS AND METHODS: An epidemiologic study of low back pain and injury was performed with questionnaires distributed to 471 women working at Yeungnam university hospital. The differences in low back pain and injuries among various hospital departments were analyzed by a one-way analysis of variance (ANOVA), and the relevant factors included in the questionnaire were determined by a factor analysis. RESULTS: The frequency of low back pain in women in the department of diet and in the maintenance department was higher than among the other departments. The frequency of low back pain was mainly related to the frequency of psychosomatic symptoms. In addition, the low back pain was partially related to the frequency of psychosomatic symptoms and partially related to the frequency of pushing during the workday. The degree of disability from low back pain was increased by lifting and hard physical work and was related to the frequency of psychosomatic symptoms and the degree of work dissatisfaction. The frequency of low back injury was increased by increased standing time during work and hard physical work. The frequency of low back injury was related to advancing age and in part to psychosomatic symptoms. CONCLUSION: Lower back pain and its associated complications are related to psychosomatic factors and type of work. Lower back injury is related to physiological factors such as age. For the prevention and treatment of lower back pain, a multidisciplinary approach is required.

Abstract PDF

Background
：The purpose of this study was to estimate noise levels in hospital and effects of noise on patients and staff members and provide basic information required for reducing noise and improving working environment in hospital. Material and Methods：A structured questionnaire was served to patients and employees at a general hospital based in Daegu during the period from December 2004 to January 2005. Noise levels were measured at locations where noise level was high in the hospital.
Results
：Of total employee respondents, 95.8% cited work interruption and 94.5% cited interruption in conversation as noise disturbance. Also, 98.7% of total employees respondents regarded noise in hospital as a nuisance. Those working in intensive care units (58.8%) and boiler maintenance room (66.7%) said noise level was high all day. Those working in Nutrition Division (47.5%) said noise level was high in the morning between 10 and 11 a.m. Patients in the hospital cited sleep disturbance (59.0%), nuisance (38.0%) and interruption in conversation (38.0%) as a consequence of noise. Of these patients, 75.0% said they were just tolerating noise. By the source of noise, patients described talks between patient and family member who sharing the same room, visitors, squeak noise from beds and chairs, trolley, telephone bell and toilet flush.
Conclusion
：Noise in the hospital resulted in sleep disturbance, nuisance and interruption in conversation for patients and poor working environment, reduced performance and interruption in conversation for employees. Noise control seems imminent to make hospital environment comfortable for both patients and employees.

Abstract PDF: BACKGROUND
The causes of chest pain vary but the leading cause of chest pain is ischemic heart disease. Mortality from ischemic chest pain has increased more than two fold over the last ten years. The purpose of this study was to determine the data necessary for rapid treatment of patients with signs and symptoms of ischemic chest pain in the emergency department (ED). MATERIALS AND METHODS: We interviewed 170 patients who had ischemic chest pain in the emergency department of Yeungnam University Hospital over 6 months with a protocol developed for the evaluation. The protocol used included gender, age, arriving time, prior hospital visits, methods of transportation to the hospital, past medical history, final diagnosis, and outcome information from follow up. RESULTS: Among 170 patients, there were 118 men (69.4%) and the mean age was 63 years. The patients diagnosed with acute myocardial infarction (AMI) were 106 (62.4%) and with angina pectoris (AP) were 64 (37.6%). The patients who had visited another hospital were 68.8%, twice the number that came directly to this hospital (p<0.05). The ratio of patients who visited another hospital were higher for the AMI (75.5%) than the AP (59.4%) patients (p<0.05). The median time spent deciding whether to go to hospital was 521 minutes and for transportation was 40 minutes. With regard to patients that visited another hospital first, the median time spent at the other hospital was 40 minutes. The total median time spent before arriving at our hospital was 600 minutes (p>0.05). The patients who had a total time delay of over 6 hours was similar 54.8% in the AMI group and 57.9% in the AP group (p>0.05). As a result, only 12.2% of the patients with an AMI received thrombolytics, and 48.8% of them had a simultaneous percutaneous coronary intervention (PCI). In the emergency department 8.5% of the patients with an AMI died. CONCLUSION: Timing is an extremely important factor for the treatment of ischemic heart disease. Most patients arrive at the hospital after a long time lapse from the onset of chest pain. In addition, most patients present to a different hospital before they arrive at the final hospital for treatment. Therefore, important time is lost and opportunities for treatment with thrombolytics and/or PCI are diminished leading to poor outcomes for many patients in the ED. The emergency room treatment must improve for the identification and treatment of ischemic heart disease so that patients can present earlier and treatment can be started as soon as they present to an emergency room.
