Evaluating attitudes, behaviors, and relevant factors in dispensing antibiotics without prescription by pharmacies: a cross-sectional study in Vietnam.

Objectives: To standardize a questionnaire about drug dispensers' attitudes and behaviors in dispensing antibiotics without prescription, and to evaluate drug dispensers' attitudes, behaviors, and relevant factors in dispensing antibiotics without prescription at community pharmacies in Can Tho City, Vietnam. Methods: A descriptive cross-sectional study was conducted among community pharmacists in Can Tho City, Vietnam from June to December 2022. A self-administered questionnaire designed according to the Theory of Planned Behavior was used for data collection. The questionnaire was composed of 33 statements scored on the 5-point Likert scale, which was completed by interviews with 180 pharmacy dispensers to Can Tho. Exploratory Factor Analysis was also utilized to uncover major determinants of dispensing antibiotics without prescription. Results: Of the 180 participants, 65% of drug dispensers were female (n=117), 59.4% were university graduates (n= 107), and 80.6% had experience of less than 10 years (n=145). A pharmacy is the first destination people think about when they have a health issue. Unfortunately, dispensing antibiotics without a valid prescription is not in compliance with governmental regulations. In the study, perceived behavioral control factors were found to be the most critical determinants of the behavior, followed by subjective norms. By contrast, attitudinal factors presented no impact on intention to dispensing antibiotics without prescription. Conclusions: The provision of non-prescription is primarily influenced by the perception of the distributors and external factors. Developing interventions is necessary to increase public awareness of the misuse and misunderstanding of antibiotics.

Assessment of morphological and hemodynamic changes in adult atrial septal defect before and after percutaneous trans-catheter closure: the initial result in Vietnamese patient.

OBJECTIVE: This study aimed to evaluate the change of morphology and hemodynamics in a relatively large number of patients with atrial septal defect (ASD) and provide the initial result in Vietnamese patients. PATIENTS AND METHODS: This longitudinal, prospective case-control study was done at the Vietnam National Heart Institute from January 2012 to December 2017. The participants were divided into two groups: the ASD group, which included patients with ASDs, and the control group, which included healthy individuals or individuals without cardiac-related disorders. RESULTS: There were 94 participants in the ASD group and 83 participants in the control group. Most patients with ASDs in the study group were female, and the average age was 38.65 ± 14.8. The success rate of the ASD group was 98.9%. The right ventricle morphology and function showed right ventricular diameter, pulmonary trunk gradually decreased, FAC and ET increased, IVCT and IVRT decreased, and Tei index gradually decreased after each examination. Morphology and function of the left ventricle after ASD closure showed that the left ventricular diameter gradually increased, and EF% in 3 months after ASD closure increased statistically significantly. IVCT, IVRT, and LV Tei index decreased, and ET increased statistically significantly. After six months from ASD closure, the proportion of patients with NYHA I was 90.3%, with no patient with NYHA IV, and pulmonary vascular resistance gradually decreased. CONCLUSIONS: Percutaneous trans-catheter closure in Vietnamese adult atrial septal defect was an effective technique. Ventricle morphological and hemodynamic abnormalities following closure recovered statistical significance over time, particularly in the left ventricle.
