Hospital effluents represent an important source for the release of antibiotics and antibiotic resistant bacteria into the environment. This study aims to determine concentrations of various antibiotics in wastewater before and after wastewater treatment in a rural hospital (60 km from the center of Hanoi) and in an urban hospital (in the center of Hanoi) in Vietnam, and it aims to explore the relationship between antibiotic concentrations in wastewater before wastewater treatment and quantities of antibiotics used in the rural hospital, over a period of one year in 2013. Water samples were collected using continuous sampling for 24 h in the last week of every month. The data on quantities of antibiotics delivered to all inpatient wards were collected from the Pharmacy department in the rural hospital. Solid-phase extraction and high performance liquid chromatography-tandem mass spectrometry were used for chemical analysis. Significant concentrations of antibiotics were present in the wastewater both before and after wastewater treatment of both the rural and the urban hospital. Ciprofloxacin was detected at the highest concentrations in the rural hospital’s wastewater (before treatment: mean = 42.8 µg/L; after treatment: mean = 21.5 µg/L). Metronidazole was detected at the highest concentrations in the urban hospital’s wastewater (before treatment: mean = 36.5 µg/L; after treatment: mean = 14.8 µg/L). A significant correlation between antibiotic concentrations in wastewater before treatment and quantities of antibiotics used in the rural hospital was found for ciprofloxacin (r = 0.78; p = 0.01) and metronidazole (r = 0.99; p < 0.001).

The environmental spread of antibiotic-resistant bacteria has been recognised as a growing public health threat for which hospitals play a significant role. The aims of this study were to investigate the prevalence of antibiotic resistance and antibiotic resistance genes (ARGs) in Escherichia coli isolates from hospital wastewater in Vietnam. Wastewater samples before and after treatment were collected using continuous sampling every month over a year. Standard disk diffusion and E-test were used for antibiotic susceptibility testing. Extended-spectrum beta-lactamase (ESBL) production was tested using combined disk diffusion. ARGs were detected by polymerase chain reactions. Resistance to at least one antibiotic was detected in 83% of isolates; multidrug resistance was found in 32%. The highest resistance prevalence was found for co-trimoxazole (70%) and the lowest for imipenem (1%). Forty-three percent of isolates were ESBL-producing, with the blaTEM gene being more common than blaCTX-M. Co-harbouring of the blaCTX-M, blaTEM and qepA genes was found in 46% of isolates resistant to ciprofloxacin. The large presence of antibiotic-resistant E. coli isolates combined with ARGs in hospital wastewater, even post-treatment, poses a threat to public health. It highlights the need to develop effective processes for hospital wastewater treatment plants to eliminate antibiotic resistant bacteria and ARGs.

Staff practice, driven by knowledge, plays a decisive role in hospital infection control. This study aimed to assess and compare knowledge and self-reported practices of infection control among various occupational groups in a rural and an urban hospital in Vietnam. Questionnaires consisting of items on knowledge and practices were collected from 339 hospital staff with varying occupations. For analysis, total knowledge or practice score ranged from 0–15. Mood’s median test was performed to compare median scores. Post-hoc analysis of ordinal logistic regression models was applied to test differences in scores among occupational groups. The majority of hospital staff had good or adequate knowledge (median score: rural = 11.8; urban = 12), but the score range was wide (1.4–14.5). Self-reported practices in the urban hospital were likely to be better than in the rural one (p = 0.003). Self-reported practices yet not completely satisfactory, indicating the need for continuing professional development in both settings. Overall, cleaners had lower scores than both physicians and nurses, highlighting the need for tailored education in this topic. Future infection control strategies within the hospitals might want to assess the difference between the staff’s self-reported practice and their actual real practice. These findings can be of value in many other similar settings.

Adequate infection control plays a key role in preventing healthcare-associated infections (HAIs). This study aimed to explore staff perceptions of hospital infection control in a rural and an urban hospital in Vietnam. Individual interviews were conducted with hospital managers, and focus group discussions were conducted with doctors, nurses and cleaning workers separately. Content analysis was applied. An interview guide including discussion points on HAIs, hand hygiene and healthcare waste management was used. Generally, the staff were knowledgeable of hospital infection control, but they were not aware of the situation in their own hospital, and infection control practices in the hospitals remained poor. Reported difficulties in infection control included lack of resources, poor awareness and patient overload. A main theme emerged: ‘Making data on HAIs available for health workers can improve their awareness and motivate them to put their existing knowledge into practice, thus decreasing the know-do gap in infection control’. This could be a feasible intervention to improve infection control practice in the hospitals with limited resources, high workload and patient overload.

Background: Antimicrobial resistance (AMR) including antibiotic resistance is considered one of the greatest threats to global health with an important reason being irrational use of antibiotics in the community. In Vietnam, antimicrobial stewardship programs (ASP) have mostly been implemented in hospitals. Understanding the perceptions and practices of community pharmacists towards antimicrobial stewardship is crucial for developing and implementing effective ASPs in the community setting. Objective: To assess the perceptions and practices regarding antimicrobial stewardship among pharmacists working in community pharmacies in Chuong My district, Hanoi, Vietnam. Methods: This was a cross-sectional study. A structured questionnaire was distributed to pharmacists working in community pharmacies. Descriptive statistics, as well as Mann-Whitney and Kruskal-Wallis tests, were used for data analysis. Results: Community pharmacists were aware of the importance of antimicrobial stewardship. The study participants perceived that antimicrobial stewardship could reduce inappropriate use of antibiotics in the community (98%); They also perceived the need for continuous training related to antimicrobial stewardship (95%). Additionally, 80.8% of the participants supported integrating ASPs into community pharmacy practice. However, inappropriate antibiotic dispensing practices were self-reported. Specifically, 89.9% of the participants have dispensed antibiotics without prescriptions; 71.7% based on customer requests and 88.9% based on their own assessment of symptoms. Conclusions: Therefore, drug administration authorities need to strengthen periodic inspections, especially to develop and implement community-based antibiotic stewardship programs targeting drug retail establishments. Regular continuous trainings organised by pharmaceutical training institutions or pharmacy associations on antimicrobial stewawrdship for community pharmacists can enhance their knowledge, thus improve their practices towards appropriate use of antibiotics in the community.
