Safety of antimicrobial de-escalation for culture-negative severe pneumonia.

PURPOSE: This study investigated the outcomes of antimicrobial de-escalation (ADE) based on mortality and the incidence of multi-drug resistant (MDR) pathogen occurrence in patients with culture-negative pneumonia presenting with sepsis and septic shock. MATERIALS AND METHODS: We retrospectively analyzed patients diagnosed with severe pneumonia requiring intensive care unit (ICU) admission and possessing negative microbiological culture results at a tertiary referral hospital in South Korea from March 2008 to July 2018. RESULTS: We identified 107 patients with culture-negative pneumonia. The Acute Physiologic and Chronic Health Evaluation (APACHE) II and Sepsis-related Organ Failure Assessment (SOFA) mean scores were 20.3 ±â€¯8.6 and 9.6 ±â€¯3.3, respectively. Among the patients, 40 (37.4%) underwent ADE. The APACHE II, SOFA, and follow-up SOFA scores did not differ significantly between the groups, and no differences were found in ICU mortality and MDR pathogen occurrence (27.5% vs 41.8%, P = .137 and 15.0% vs 16.9% P = .794, respectively). CONCLUSIONS: We observed similar ICU mortality and MDR pathogen occurrence in patients with culture-negative pneumonia presenting with sepsis/shock regardless of whether they received ADE. Additionally, ADE lowered the antimicrobial burden.

A survey of the perspectives of patients who are seriously ill regarding end-of-life decisions in some medical institutions of Korea, China and Japan.

PURPOSE: The debate about the end-of-life care decision is becoming a serious ethical and legal concern in the Far-Eastern countries of Korea, China and Japan. However, the issues regarding end-of-life care will reflect the cultural background, current medical practices and socioeconomic conditions of the countries, which are different from Western countries and between each other. Understanding the genuine thoughts of patients who are critically ill is the first step in confronting the issues, and a comparative descriptive study of these perspectives was conducted by collaboration between researchers in all three countries. METHODS: Surveys using self-reporting paper questionnaire forms were conducted from December 2008 to April 2009 in Korea (six hospitals in two regions), China (five hospitals in four regions) and Japan (nine hospitals in one region). The subjects were patients who were critically ill who had been diagnosed as having cancer. A total of 235 participants (Korea, 91; China, 62; Japan, 52) were eventually recruited and statistically analysed. RESULTS: Most respondents had sometimes or often thought of their own death, mostly fear of 'separation from loved ones'. They wanted to hear the news regarding their own condition directly and frankly from the physician. A quarter of them preferred making end-of-life care decisions by themselves, while many respondents favoured a 'joint decision' with their family members. The most favoured proxy decision maker was the spouse, followed by the children. Most admitted the necessity of 'advance directives' and agreed with artificial ventilation withdrawal in irreversible conditions. The most common reason was 'artificial prolongation of life is unnecessary'. Most respondents agreed with the concept of active euthanasia; however, significant differences were sometimes observed in the responses according to variables such as patient's country of origin, age, gender and education level. CONCLUSION: Patients in Far-Eastern countries gave various responses regarding end-of-life care decisions. Although familial input is still influential, most patients think of themselves as the major decision maker and accept the necessity of advance directives with Westernization of the society. Artificial ventilation withdrawal and even active euthanasia may be acceptable to them.
