Objective: Although Ghana National Ambulance Service (NAS) personnel are being assigned to various scenes following formal training for 1 or 2 years, it is unclear if they have sufficient capacity to handle lengthy and long-distance patient transport in various emergencies. This study examined this through an analysis of referral patients in a typical rural area of Ghana and a survey of NAS personnel. Methods: Cases of the patient group transported by NAS personnel were abstracted from the referral patients’ chart of Worawora Government Hospital (Oti region, Ghana). These charts were analyzed according to age, sex, diagnosis, and outcome. A self-assessment survey was also conducted to estimate the confidence NAS personnel had in their abilities. Results: According to the records from the Worawora Government Hospital, from January to June 2021, 770 patients were admitted, including 126 obstetrics and gynecology patients (18.0%) and 124 trauma patients (17.7%). Sixty-nine patients (9.8%) who had already been transferred from lower-level hospitals were re-transferred to teaching hospitals. Among these, 33 were trauma patients (47.8%). In the survey, NAS personnel showed high confidence in the patient evaluation section, but they showed relatively low confidence in treating obstetrics and gynecology patients. Conclusion NAS personnel in the Oti region frequently encounter obstetrics and gynecology patients, as well as trauma patients, but they appear to lack the knowledge and skills required to transport such patients. Supplementation of knowledge and technical education in these fields is essential to ensure proper prehospital management.

PURPOSE: Upper gastrointestinal bleeding (UGIB) is a common medical emergency condition in the emergency department (ED). Patients with UGIB show a wide range of clinical severity, from mild bleeding to death. The objective of this study was to evaluate methods for risk stratification of active UGIB in the ED. METHODS: We retrospectively reviewed patients with UGIB who were admitted to the ED of a tertiary care, university-affiliated hospital center from January 2011 to December 2011. Our study subjects were patients over 20 years old who complained of symptoms and signs of gastrointestinal tract bleeding and underwent endoscopic gastroduodenoscopy (EGD) evaluation. However, patients diagnosed with variceal gastrointestinal bleeding, disseminated malignancy, coagulopathy, and lower gastrointestinal bleeding and patients who did not undergo EGD within 6 hours were excluded. The Blatchford score and the clinical Rockall score were calculated for the enrolled patients. In cases where the value of each score was greater than 0, the scores were considered high risk. Active UGIB was defined as a symptom of patients who underwent emergency endoscopic intervention such as ligation or sclerotherapy. We compared the proportions of patients identified as high risk using chi tests. The areas under the receiver operating characteristic (AUROC) curve for detection of patients requiring emergency endoscopic intervention were calculated for both the Blatchford score and the clinical Rockall score. RESULTS: The numbers of patients with high risk according to the Blatchford score and the clinical Rockall were 220 (93.6%) and 192 (81.7%) of 235 patients, respectively. The number of patients with active UGIB was 96 (40.9%) of 235 patients. The sensitivity and specificity of risk stratification based on the Blatchford score was 100% (96/96) and 10.8% (15/139) (p=0.001), respectively, while those based on the clinical Rockall score were 80.2% (77/96) and 17.3% (24/139) (p>0.05). The AUROC curves of the Blatchford score and the clinical Rockall score were 0.617 (95% CI; 0.546-0.688) and 0.495 (95% CI; 0.420-0.571), respectively. CONCLUSION: The Blatchford score could be more useful as a risk stratification tool than the clinical Rockall score for active UGIB patients in the ED. The Blatchford score would be preferable as a clinical tool that can discriminate patients who need emergency endoscopic intervention for control of UGIB.

PURPOSE: This study reports the clinical features of infant, child, school aged and adolescent patients treated for acute poisoning in nationwide emergency departments (EDs). METHODS: We retrospectively analyzed clinical data pertaining to patients under 19 years of age who were treated for acute poisoning in nationwide EDs from 2013 to 2015. The data were collected by the National Emergency Department Information System (NEDIS). All patients were divided into three groups: ‘Infant and child group’ (0 to 5 years), ‘school age group’ (6 to 12 years) and ‘adolescent group’ (13 to 18 years). General characteristics, Korea Standard Classification of Disease 7(th) (KCD-7) codes and results of care were collected. RESULTS: There were 14,500 pediatric poisoning cases during the study period. The distribution of patient age was bimodal with two peaks among infant, child and adolescent group. The proportion of alert mentality at the ED visit of the infant and child group was 99.3%, while that of the adolescent group was 86.4%. The proportion of intentional intoxication was higher in the adolescent group (40.7%) than other age groups. Among children less than 13 years of age, various poisonous substances and therapeutic drugs were common. CONCLUSION: There were some clinical differences in acute poisoning patients between age groups. It is necessary to establish a preventive plan considering characteristics by age. Since the KCD-7 code has limitations in analyzing the characteristics of poisoning patients, it is necessary to consider the registration system of poisoning patients.

In this study, we investigated playground equipment related injuries in preschool-aged children. This was a retrospective observational study using Emergency Department based Injury In-depth Surveillance, (2011–2014). We included the preschool-aged children with playground equipment related injuries. We surveyed the mechanism and incidence of injuries, and estimated the odds ratio (OR) of traumatic brain injury (TBI) and upper/lower extremities fracture. There were 6,110 patients, mean age was 4.14 ± 1.95 years old. Slide and swing related injuries were 2,475 (40.5%) and 1,102 (18.0%). Fall down (48.5%) was the most common mechanism. The OR of TBI in children 0–2 years old was 1.88 times higher than children 3–7 years old, and in swing was 4.72 (OR, 4.72; 95% confidence interval [CI], 2.37–9.40) times higher than seesaw. The OR of upper extremity fracture in children 3–7 years old was 3.07 times higher than children 0–2 years old, and in climbing was 2.03 (OR, 2.03; 95% CI, 1.63–2.52) times higher than swing. The OR of lower extremity fractures in horizontal bars, tightropes, and trampolines was 2.95 (OR, 2.95; 95% CI, 1.55–5.61) times higher than swing. The most common mechanism and playground equipment were fall down and slide. TBI was associated to younger children (0–2 years old) and swing. Fracture of upper extremities was associated to older children (3–7 years old) and climbing. Fracture of lower extremities was associated to others such as horizontal bars, tightropes, and trampolines.

PURPOSE: Falling is one of the most common causes of injury for preschool children. Here, we aim to identify the characteristics and risk factors of injuries by falling-down in preschool children. METHODS: Between January 2010 and December 2011, we enrolled patients under the age of 7 years, who were injured by falling down and visited an urban regional emergency center. We retrospectively surveyed the medical record of these patients, including age, sex, place and height of fall, type of floor, guardian's witness, traumatic brain injury (TBI), and fracture of extremities. RESULTS: The odds ratios sex (male), age (under 2 years old), height of fall, type of floor (hard), and guardian's witness (presence) that resulted in TBI were 1.35 (95% confidence interval [Cl], 0.72?2.55; p=0.352), 3.83 (95% Cl, 1.78?8.65; p<0.05), 6.38 (95% Cl, 3.27–12.44;p<0.05), 3.58 (95% Cl, 0.47–27.30; p=0.218), and 1.47 (95% Cl, 0.63–3.43; p=0.377), respectively. The odds ratios sex (male), age (over 2 years old), height of fall, type of floor (soft), and guardian's witness (absence) that resulted in fractures were 1.19 (95% Cl, 0.78–1.81; p=0.433), 3.10 (95%Cl, 1.99–4.84; p<0.05), 1.98 (95%Cl, 1.19–3.29; p<0.05), 2.41 (95% Cl, 1.29–4.54; p<0.05), and 1.15 (95%Cl, 0.72–1.85, p=0.554), respectively. CONCLUSION: In preschool children who experienced an injury from falling down, TBI was increased with younger patients and higher height of fall, but it was not related with patient's sex, type of floor, and guardian's witness; conversely, fractures were increased with older patients, higher height of fall, and soft floor, but not related with patient's sex and guardian's witness.

PURPOSE: This study was conducted to describe the characteristics of patients with carbon monoxide (CO) poisoning. METHODS: We retrospectively surveyed data from the Emergency Department based Injury In-depth Surveillance of 20 hospitals (2011-2014). We included patients whose mechanism of injury was acute CO poisoning caused by inhalation of gases from charcoal or briquettes. We surveyed the annual frequency, gender, age, result of emergency treatment, rate of intensive care unit (ICU) admission, result of admission, association with alcohol, and place of accident. We also surveyed the cause and experience of past suicide attempts by intentional poisoning. RESULTS: A total of 3,405 patients were included (2,015 (59.2%) and 1,390 (40.8%) males and females, respectively) with a mean age of 39.83±18.51 year old. The results revealed that the annual frequency of CO poisoning had increased and the frequency of unintentional CO poisoning was higher than that of intentional CO poisoning in January, February and December. The mean age of intentional CO poisoning was younger than that of unintentional CO poisoning (38.41±13.03 vs 40.95±21.83) (p<0.001). The rates of discharge against medical advice (DAMA), ICU care and alcohol association for intentional CO poisoning were higher than for unintentional CO poisoning (36.4% vs 14.0%, 17.8% vs 4.7%, 45.2% vs 5.6%) (p<0.001). The most common place of CO poisoning was in one's residence. CONCLUSION: The annual frequency of total CO poisoning has increased, and unintentional CO poisoning showed seasonal variation. DAMA, ICU care, and alcohol association of intentional CO poisoning were higher than those of unintentional CO poisoning.

PURPOSE: The aim of this study is to investigate the anesthetic effect on a modified subcutaneous single-injection digital block in accordance with the location of the finger. METHODS: We recruited volunteers from the workshop training course. We injected less than 5 mL of 2% lidocaine at the volar side, between the 3rd metacarpal and proximal phalangeal joint, until the swelling in the dorsal side of the finger increased. At 10 minutes post the modified subcutaneous single-injection digital block, we recorded the pain score (0-10) using 11-point numeric rating pain scale (NRPS) according to the location of the finger (volar proximal phalanx, VPP; volar middle phalanx, VMP; volar distal phalanx, VDP; dorsal distal phalanx, DDP; dorsal middle phalanx, DMP; dorsal proximal phalanx, DPP) via a pinprick test. We analyzed and compared the NRPS on the location of the finger by the Friedman test with a Pairwise comparison. RESULTS: Fifty-eight volunteers of healthy adult were enrolled in this study. The pain scales on DPP and DMP were 7.00 (4.00-8.00) and 2.00 (1.00-4.00), respectively. The pain scales on DDP, VDP, VMP and VDP were 0.00 (0.00-2.00), 0.00 (0.00-0.00), 0.00 (0.00-1.00) and 0.00 (0.00-1.00), respectively. The pain scales on DPP and DMP were significantly different among DDP, VPP, VMP and VPP (p<0.05). There were no significant differences of pain scale on DDP, VDP, VMP and VPP (DDP vs. VDP, p=0.592; DDP vs. VMP, p=0.749; DDP vs. VPP, p>0.999; VDP vs. VMP, p>0.999; VMP vs. VPP, >0.999). CONCLUSION: A modified subcutaneous single-injection digital block should be considered useful in regional anesthesia at the volar side of the finger and the dorsal side of the distal phalanx.

PURPOSE: Tension pneumothorax is a life threatening condition. As an emergency treatment, needle thoracostomy with 50mm angiocatheter at the second intercostal space on the mid-clavicular line (2nd ICS/MCL) is recommended in the current guidelines. However, another site has been suggested in some studies. The purpose of this study was to determine whether the current procedure should be changed, by comparing the chest wall thicknesses (CWT) at the 2(nd) ICS/MCL and the 5(th) ICS/AAL (anterior axillary line) of injured patients. METHODS: A retrospective observational study was performed in an emergency center between May 2009 and December 2011. Medical records and computed tomography (CT) images of 140 included patients were reviewed. CWT at the 2(nd) ICS/MCL was compared with the 5(th) ICS/AAL. Moreover, the relationship between BMI (body mass index) and CWT was evaluated. RESULTS: CWT of the 2(nd) ICS/MCL was 31.7±8.5 mm on the right and 31.6±8.8 mm on the left, with no differences (p=0.42). CWT of the 5(th) ICS/AAL was 28.1±8.5 mm on the right and 27.8±7.7 mm on the left, also with no differences (p=0.30). CWT of the 2(nd) ICS/MCL was thicker than that of the 5(th) ICS/AAL (p<0.001). Nevertheless, CWT of all sites were not thicker than 50 mm (p<0.001). BMI was positively correlated with CWT. CONCLUSION: There was insufficient amount of evidences shown in this study to change the current guidelines of needle thoracostomy. However, in case of obvious patients, a long needle and 5(th) ICS/AAL site should be considered for needle thoracostomy, because CWT tended to increase as BMI increased.

The Kaeseong Industrial District (KID) is a special economic zone that is being managed in partnership by North Korea and South Korea. The Kaeseong Industrial District Medical Clinic (KIDMC) was founded to deliver healthcare services to South Korean workers staying at the KID. The purpose of this study is to understand the clinical manifestations of the patients who visited the KIDMC from January 2013 to November 2014. All data were collected by analyzing the medical records of the patients. Gender, age, vital signs, and causes of visits were collected. The causes of visits to the clinic were categorized according to the Korean Standard Classification of Causes of Death and Disease, 6th edition. Information about the patients who underwent emergency evacuation from the KID to South Korea was reviewed in depth. The number of patients included in this study was 1,199. The total number of clinic visits was 2,548 and 3,873 in 2013 and 2014, respectively. The most common reason for a visit was respiratory problems (34.99%). During the study period, 103 patients underwent emergency evacuation from the KID during the study period. The most common reason for evacuation was trauma (20.39%). The mean time of emergency evacuation from the KIDMC to the southern office of Customs, Immigration and Quarantine was 176 minutes. We concluded that the KIDMC must obtain medical equipment and human resources for patients with various health conditions. Furthermore, equipment and medical staff should be obtained, and a system established, for fast, safe evacuation. We expect that this study provides information that would be valuable for such efforts.

OBJECTIVE: International emergency medicine (IEM) is a rapidly growing field in emergency medicine (EM). However, there are few studies of the interest and attitude of EM residents on this subject in Korea. The aim of this study was to assess the awareness of IEM and determine feasibility of adoption as an EM residency program. METHODS: A structured on/off-line survey was distributed to all current first to third grade EM residents in Korea (year 2016–2017). Ninety-two hospitals with residency programs and 463 residents were identified as potential survey candidates. The survey consisted of 20 questionnaires including binary yes/no and multiple choice questions. RESULTS: The response rate was 37.1% (172/463). The proportion of residents who have interest in IEM was 62.8% (108/172); 76.2% (131/172) respondents answered that they wanted to participate in IEM/global health activities during their residency. Approximately two thirds (68.6%, 118/172) reported that they plan to participate in any IEM activity even after graduation. More than half (56.4%, 97/172) agreed that the inclusion of IEM/global health training in their residency might be necessary and it may help them to guide their future careers after their training (68.6%, 118/172). A total of 144 respondents (83.7%) indicated lack of time during their residency mostly, absence of an IEM program (47.1%, 81/172), and lack of information on IEM (31.4%, 54/172). CONCLUSION: IEM is of interest to Korean EM residents. On the other hand, formal education and training offered to residents is limited in Korea. Korean Society of Emergency Medicine should start discussions on how to adopt a global IEM agenda, and reflect on a resident training program.
