The treatment of carbapenem-resistant Enterobacteriaceae (CRE) is diverse in each region due to the difference in local resistant patterns of CRE. We aimed to explore how physicians in Thailand decide on selection options for treating CRE infections. In this study, 25 physicians who were not infectious disease (ID) specialists participated in this semi-structured in-depth interview. We found that they, in general, did not provide empiric antibiotics for the treatment of CRE. However, some patients, e.g., those with prior carbapenems exposure may have brought CRE to physicians’ attention. ID specialists played critical roles in both empiric and specific CRE treatment. There were multiple scenarios when CRE management deviated from recommendations, especially when physicians perceived that the evidence that supported the recommendations was weak. Several supportive factors, challenges, and improvements were also suggested. In conclusion, ID specialists, adequate information, and consistent implementation of infectious control policy are crucial to the treatment and prevention of CRE infection.

World Health Organization (WHO) released the treatment manual of diarrhea in 2005. We aimed to investigate the rationale for selecting medications for acute infective diarrhea in Thai community pharmacies and to see if the selection complied with the WHO manual.A theoretical 18-year-old patient with acute infective diarrhea was used for interviews. The protocol and materials for the research were approved by Institutional Review Board. A total of 30 drugstore personnel were selected by convenience sampling and included. The first author manually coded, extracted for themes, and translated the transcript. Participants did not dispense oral rehydration salt because of the feeling that diarrhea was not severe.Absorbents were dispensed because they were perceived as the first-line medication for noninfective or mild diarrhea. Antibiotics were dispensed because of the concerns for the prognosis and the expected patient pressure. None provided zinc to the patient because of the lack of knowledge of the indication of zinc. We found that dispensing for acute infective diarrhea in Thai drugstores deviated from the WHO treatment guideline. The reasons were that the pharmacy personnel were not practicing evidence-based medicine, the lack of knowledge, the patient pressure, the unavailability of products, and the perceived availability of information in local guidelines.

Drug-induced corrected QT (QTc) prolongation can cause Torsade de Pointes (TdP) which leads to severe arrhythmia or sudden cardiac death. However, information on the prevalence of QTc prolongation in coronavirus disease 2019 (COVID-19) patients and risk factors is limited. A retrospective chart review was conducted in COVID-19 patients admitted to Chonburi Hospital from April to October 2020. The outcomes were the incidence of QTc prolongation and prevalence of risk factor QTc prolongation. We included 29 COVID-19 patients. After treatments were initiated, QTc prolongation occurred in 17 patients (58.62%). QT prolongation could be found as early as two days after the treatment initiation (median = 6 days interquartile range [IQR], 4–7). The median QTc interval in those 17 patients increased from 410 (IQR, 399.5–425.0) ms to 460 (453.50–466.50) ms, with the maximum QTc interval of 488 ms. They were treated with multiple drugs that were reported as a cause of QTc prolongation. 64.71% (n = 11) of them were treated with chloroquine. The median TdP risk score in patients with and without QTc prolongation was 3 (IQR, 2–3) and 2 (IQR, 1–2), respectively. The percentage of patients with comorbidities including atrial fibrillation, bradycardia, concomitant use of diuretics, diabetes, electrolyte imbalance was higher in patients with QTc prolongation. COVID-19 patients were treated with multiple drugs that were reported as a cause of QTc prolongation. COVID-19 patients with QTc prolongation had more comorbidities that are risk factors for QTc prolongation.
