Evaluating the Quality of Basic Life Support Information for Primary Korean-Speaking Individuals on the Internet / 의료커뮤니케이션

PURPOSE: The aim of this study is to investigate the quality of basic life support (BLS) information for primary Korean-speaking individuals on the internet.METHODS: Using the Google © search engine, we searched for the terms ‘CPR’, ‘cardiopulmonary resuscitation (in Korean)’ and ‘cardiac arrest (in Korean)’. The accuracy, reliability and accessibility of web pages was evaluated based on the 2015 American heart association(AHA) guidelines for CPR & emergency cardiovascular care, the health on the net foundation code of conduct and Korean web content accessibility guidelines 2.1, respectively.RESULTS: Of the 178 web pages screened, 50 met criteria for inclusion. The overall quality of BLS information was not enough (median 5/7, IQR 4.75-6). 23(36%) pages were created in accordance with 2010 AHA guidelines. Only 24(48%) web pages educated on how to use the automated electrical defibrillator. The attribution and transparency of the reliability of pages was relatively low, 20(40%) and 16(32%). The web accessibility score was relatively high.CONCLUSION: A small of proportion of internet web pages searched by Google have high quality BLS information for a Korean-speaking population. Web pages based on past guideline were still being searched. The notation of the source of CPR information and the transparency of the author should be improved. The verification and evaluation of the quality of BLS information exposed to the Internet are continuously needed.

Comparison of the Risk Stratification Tools Including the Blatchford Score and the Clinical Rockall for Nonvariceal Upper Gastrointestinal Bleeding in the Emergency Department

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.
