The Kaplan–Meier method was used to calculate the cumulative survival rate, and the Log rank test was used to analyze the factors associated with the survival rate of patients.Results: This study enrolled a total of 68 patients with a mean age of 71.93 ± 7.44 years at the initiation of CAPD. The most common complication among kidney failure patients was diabetic nephropathy (39.71%). The rate of concomitant cardiovascular diseases was 58.82%. The average survival rate was 45.59 ± 4.01 months. Peritonitis was the most common factor causing death (31.25%), followed by cardiovascular diseases (28.12%) and malnutrition (25%). The factors that impacted the survival rate included concomitant cardiovascular diseases, low serum albumin (< 35 g/dL), and an indication of CAPD due to exhausted vascular access for hemodialysis at baseline. The main factor associated with a shorter survival time was concomitant cardiovascular diseases.Conclusion: It is necessary to improve the survival time beyond 5 years for elderly patients undergoing CAPD, especially for those with concomitant cardiovascular diseases. Besides the prevention of peritonitis, adequate measures to protect from cardiovascular diseases and malnutrition will reduce the mortality rate in patients on CAPD.Keywords: CAPD, elderly, Vietnamese, concomitant diseases, cardiovascular diseases

Direct-acting antivirals (DAAs) have revolutionized hepatitis C virus (HCV) treatment through their high cure rates and improved safety profiles. We aimed to evaluate the efficacy and safety, and identify the optimal combination, of DAAs for the treatment of chronic HCV. A retrospective study was conducted of 613 patients with chronic HCV who were treated with DAAs. Demographic, HCV genotype, treatment regimen, virological response, and adverse drug event (ADE) data were collected at the initial visit and 4, 8, 12, and 24 weeks later. The rapid virologic response (RVR) and sustained virologic response (SVR) rates were 90.4% and 97.8% for HCV genotype 1, 89.2% and 98.7% for genotype 6, 92.8% and 99% for genotype 2, and 90.9% and 100% for mixed genotype 2/6 or unspecified genotypes, respectively. There were no significant differences in the RVR and SVR rates for the various DAA regimens. The mean ALT, AST, and GGT activities decreased, and the PLT count increased during the treatments. ADEs occurred in 8% of the patients. The commonest ADEs were itching (3.1%), fatigue (1.8%), and dizziness (1.1%). None of the patients discontinued treatment because of an ADE. Posttreatment disease progression occurred in 7.7% of the patients, including liver fibrosis (3.6%), cirrhosis (1.1%), hepatocellular carcinoma (1.1%), and high alpha-fetoprotein (AFP) (1%). The factors associated with the achievement of RVR were low viral load, the use of sofosbuvir/ledipasvir or sofosbuvir/daclatasvir regimens, and a treatment duration of 12 weeks. No specific factors were found to be associated with the achievement of SVR. Posttreatment disease progression was associated with a high AFP and the use of sofosbuvir/ledipasvir. Thus, DAAs are highly effective and well-tolerated means of treating chronic HCV, and significantly improve patient outcomes. Their high efficacy and favorable safety profiles highlight the importance of early diagnosis and the use of personalized treatment strategies., (© 2024 The Author(s).

Objectives: To evaluate the impact of clinical pharmacist-led interventions on the switch from intravenous (IV) to oral (PO) antibiotics among inpatients with infectious diseases., Methods: A before-and-after study was conducted among inpatients aged 18 or older who were diagnosed with infectious diseases and received IV antibiotics for at least 24 h at the Thong Nhat Hospital during the pre-intervention (between January 2021 and June 2021) and intervention (between January 2022 and June 2022) periods. Information on patient characteristics, antibiotic usage, length of hospital stay and treatment outcomes was obtained from medical records. The interventions included introducing IV-to-PO switch guidelines to physicians and clinical pharmacists' feedback on eligible cases. The impact of the pharmacists' interventions was evaluated by comparing primary outcomes (switch rate and appropriateness of switching) and secondary outcomes (duration of IV therapy, length of hospital stay and treatment outcomes) between the two study periods., Results: We included 99 patients in the pre-intervention and 80 patients in the intervention period. The proportion of patients who switched from IV-to-PO antibiotics increased from 44.4% in the pre-intervention period to 67.8% in the intervention period (p = 0.008). The overall rate of appropriate conversion increased significantly from 43.8% to 67.5% (p = 0.043). There were no statistically significant differences between the two periods with respect to the median duration of IV therapy (9 days vs. 8 days), length of hospital stay (10 days vs. 9 days) and treatment outcomes. Logistic regression analysis showed that the interventions resulted in a higher switch rate, whereas age was negatively associated with the switching rate., Conclusions: The implementation of clinical pharmacist-led interventions was effective in promoting IV-to-PO antibiotic conversion., (© 2023 John Wiley & Sons Ltd.)

Background: Invasive gastrointestinal surgery may be performed as an open or endoscopic procedure, such as laparoscopic semi-colon surgery, laparoscopic appendectomy, laparoscopic gastrectomy, and anal surgery, among other such operations. Regardless of the approach, the operative procedure interferes with the patient's gastrointestinal tract, necessitating the rational use of prophylactic antibiotics to improve treatment outcomes and minimize postoperative infections., Objective: To investigate the prophylactic and postoperative antibiotic usage in patients who underwent invasive gastrointestinal surgery, and to identify factors associated with postoperative infection., Design: This descriptive, cross-sectional study included 112 patients who underwent invasive gastrointestinal surgery at the Department of Gastroenterology, Thong Nhat Hospital. We conducted a cross-sectional study in all inpatients aged 18 years and older, who underwent invasive gastrointestinal surgery between January 2020 and December 2020. We recorded patient characteristics, the administration and appropriateness of antibiotics, as well as treatment outcomes. The appropriateness of prophylactic and postoperative antibiotic usage was assessed based on 2015 Vietnamese national guideline for antibiotic use. Multivariable logistic regression analysis was used to determine the factors associated with postoperative infection., Results: Patients' mean age was 59.7 ± 17.2 years. Most surgeries (89.3%) were clean-contaminated procedures. The rates of appropriate types of antibiotics selected, doses, and overall rates of appropriateness of antibiotic prophylaxis were 68.0%, 76.4% and 54.7%, respectively. Of the patients investigated, 34.8% had at least one sign of postoperative infection; the overall appropriate rate of postoperative antibiotic was 38.5%. Old age was associated with postoperative infection and longer length of hospitalization., Conclusion: Implementation of the guidelines recommended for the prophylactic and therapeutic use of antibiotics is essential to improve treatment outcomes., (© 2022.

Objectives: We investigated the characteristics of prophylactic antimicrobial use in clean and clean-contaminated surgical procedures and assessed the efficacy of a prophylactic antimicrobial stewardship intervention at Thong Nhat Hospital, Ho Chi Minh City, Vietnam., Methods: A cross-sectional study was conducted on 354 patients who underwent either clean or clean-contaminated surgical procedures at Thong Nhat Hospital. Eligible patients were classified with respect to three periods of intervention from 2017 to 2020. Data collection included surgical procedures, patient characteristics, and prophylactic antimicrobial usage. We determined the efficacy of antimicrobial stewardship intervention based on comparisons among the primary outcome (the appropriateness of prophylactic antimicrobials) and secondary outcomes (postoperative antimicrobial prophylaxis (AP) prolongation, length of postoperative hospital stay, and cost of antimicrobials)., Results: The mean age of patients in periods 1, 2, and 3 was 54.5 ± 16.6, 50.2 ± 16.5, and 52.8 ± 17.3 years, respectively, with an overall male/female ratio of 1.1/1. No significant differences were detected in basic patient characteristics during the three periods. Majority of the surgical procedures were clean (56%-59%) and scheduled (85%-86%). Prophylactic antimicrobial stewardship intervention enhanced AP appropriateness (by 12.7%, 12.7%, and 39.0% in periods 1, 2, and 3, respectively, p < 0.001), decreased postoperative prophylactic antimicrobial duration [3.0 (0-6), 1.5 (0-5), and 0.0 (0-1) days, respectively, p < 0.001], and reduced average antimicrobial expenses (p < 0.001)., Conclusions: The prophylactic antimicrobial stewardship interventions introduced at Thong Nhat Hospital had several positive impacts on the appropriateness of prophylactic antimicrobial use and treatment costs., (© 2022 John Wiley & Sons Ltd.)

Objectives: End-stage renal disease (ESRD) is a chronic disease that can adversely affect the patient's quality of life (QoL) in terms of functional limitation and cognitive impairment. This study aimed to identify the factors associated with QoL in patients with ESRD undergoing dialysis at a national hospital in Vietnam., Methods: A descriptive cross-sectional study was conducted among outpatients aged ≥18 years who underwent haemodialysis (HD) or peritoneal dialysis (PD) for at least 3 months at Thong Nhat Hospital, Ho Chi Minh City, Vietnam from May 2020 to July 2021. QoL was measured using the validated Vietnamese version of the EuroQol-5 Dimensional-5 Level (EQ-5D-5L). The factors associated with the QoL of patients with ESRD undergoing dialysis were identified using multiple linear regression analysis., Results: In total, 131 (73.6%) and 47 (26.4%) patients underwent HD and PD, respectively. Overall, 178 (55.6%) patients were men (median age, 66 [56-79] years). The mean EQ-5D-5L score was significantly higher in patients undergoing PD than in those undergoing HD (0.848 ± 0.183 vs. 0.766 ± 0.231; p = 0.030). Older age (β = -0.006; p < 0.001) and peptic ulcer disease (β = -0.083; p = 0.029) were associated with lower QoL scores. PD treatment was associated with higher QoL scores (β = 0.065; p = 0.046)., Conclusions: It is necessary to improve the QoL of patients undergoing dialysis, especially of elderly patients and patients with peptic ulcer disease. PD may be a better method for maintenance dialysis, if applicable, in terms of QoL., (© 2021 John Wiley & Sons Ltd.)

Objectives: To assess the appropriateness of empirical antimicrobial therapy for sepsis and septic shock and determine factors associated with patient treatment outcomes at a Vietnamese national hospital., Methods: A cross-sectional study was conducted on 134 patients diagnosed with sepsis and/or septic shock at Thong-Nhat Hospital, Ho Chi Minh City, Vietnam, from January 2018 to June 2018. Appropriateness of antimicrobial therapy was defined as physician adherence to antimicrobial guidelines using the Sanford Guide to Antimicrobial Therapy and the Vietnam national guidelines. Bayesian model averaging technique was used to identify the related factors associated with patient treatment outcomes., Results: The median age of patients was 70 years. Organisms were identified in 54.5% of cases and predominated by Escherichia coli and staphylococci. Appropriate empirical antimicrobial agents were initiated in 56.6% ( n  = 73) of all cases. Of these patients, 31 cases (42.5%) and 61 cases (83.6%) received the antimicrobials in accordance with recommendations related to dosage and route of administration, respectively, bringing the overall rate of appropriate empirical antimicrobial therapy down to 23.3%. Patients who progressed to septic shock, received inappropriate antimicrobial therapy and required ICU admission were more likely to suffer treatment failure., Conclusions: The study findings suggest that clinicians should appropriately adhere to antimicrobial guidelines, especially in patients with septic shock and those who require ICU care, to improve treatment outcomes., (© The Author(s) 2021.
