Background The role of ivermectin in the treatment of moderate coronavirus disease 2019 (COVID-19) is controversial. We performed an open label randomized controlled trial to evaluate the role of ivermectin plus favipiravir-based standard of care versus favipiravir-based standard of care for the treatment of moderate COVID-19 infection. Materials and Methods An open-label randomized control trial was performed at Thammasat Field Hospital and Thammasat University Hospital from October 1st, 2021 to May 31st, 2022. Patients with moderate COVID-19 infections were randomized to the intervention (ivermectin plus favipiravir-based standard of care) or control group (favipiravir-based standard of care alone). Patients were followed up to 21 days. The primary outcome was the improvement in World Health Organization (WHO) category ordinal scale by 2 points. Secondary outcomes included duration of illness, development of severe COVID-19, and adverse reactions. Results There were 157 patients in the intervention and 160 patients in the control group. Characteristics, underlying diseases, and risk factors for severe COVID-19 were comparable in both groups. Improvement in the WHO-category ordinal scale by 2 points was achieved in 98.7% of the intervention group and in 99.4% of the control group (relative risk [RR]: 0.487; 95% confidence interval [CI]: 0.044-5.430). The median illness duration was 5.0 days (range, 3 - 28 days) in intervention group versus 5.2 days (range, 3 - 28 days) in control group (P = 0.630). Severe COVID-19 that required intensive care occurred in 2 patients (1.3%) in the intervention group and 1 patient (0.6%) in the control group (RR: 2.052; 95% CI: 0.184 - 22.857). No significant difference in serious drug adverse events was seen. Conclusion In this study ivermectin plus standard of care was not associated with improvement in the WHO-category ordinal scale, reduced illness duration, or development of severe COVID-19 in moderately ill COVID-19 patients.

Environmental cleaning and disinfection practices have been shown to reduce microorganism bioburden in the healthcare environment. This study was performed in four intensive care units in Thailand. Five high-touch surfaces were sampled before and after terminal manual cleaning and disinfection, and after pulsed xenon UV (PX-UV). Five nursing station sites were collected on a weekly basis before and after terminal manual cleaning. There were 100 patient rooms—50 rooms in the intervention arm and 50 rooms in the control arm—plus 32 nursing station sites. In the intervention arm, rooms with positive Gram-negative microorganisms were reduced by 50% after terminal manual cleaning and disinfection (p = 0.04) and 100% after PX-UV disinfection (p < 0.001). On five nursing station sites, colony counts of Gram-negative contamination decreased by 100% (p < 0.001) in the intervention arm while decreasing by 65.2% (p = 0.03) in the control arm after terminal manual cleaning and disinfection. The in-room time use was 15.6 min per room. A PX-UV device significantly reduced the level of Gram-negative microorganisms on high-touch surfaces in intensive care units. The application of a PX-UV device was practical a in resource-limited setting without compromising cleaning and disinfection times. [ABSTRACT FROM AUTHOR]

Vancomycin Area Under the Curve (AUC) monitoring has been recommended to ensure successful clinical outcomes and minimize the risk of nephrotoxicity, rather than traditional trough concentration. However, vancomycin AUC monitoring by a pharmacist-led multidisciplinary team (PMT) has not been well established in Southeast Asia. This study was conducted at Thammasat University Hospital. Adult patients aged ≥ 18 years who were admitted and received intravenous vancomycin ≥48 h were included. The pre-PMT period (April 2020–September 2020) was defined as a period using traditional trough concentration, while the post-PMT period (October 2020–March 2021) was defined as a period using PMT to monitor vancomycin AUC. The primary outcome was the rate of achievement of the therapeutic target of an AUC/MIC ratio of 400–600. There was a significantly higher rate of achievement of therapeutic target vancomycin AUC during post-PMT period (66.7% vs. 34.3%, p < 0.001). Furthermore, there was a significant improvement in the clinical cure rate (92.4% vs. 69.5%, p < 0.001) and reduction in 30-day ID mortality (2.9% vs. 12.4%, p = 0.017) during the post-PMT period. Our study demonstrates that PMT was effective to help attain a targeted vancomycin AUC, improve the clinical cure rate, and reduce 30-day ID mortality. This intervention should be encouraged to be implemented in Southeast Asia. [ABSTRACT FROM AUTHOR]

Methicillin-resistant Staphylococcus aureus (MRSA) is a significant causative agent of hospital-acquired infections. We characterized MRSA isolated from August 2012 to July 2015 from Thammasat University Hospital. Genotypic characterization of MRSA SCCmec type II and III isolates were scrutinized by whole genome sequencing (WGS). The WGS data revealed that the MRSA SCCmec type II isolates belonged to ST764 previously reported mainly in Japan. All of tested isolates contained ACME Type II′, SaPIn2, SaPIn3, seb, interrupted SA1320, and had a virulence gene profile similar to Japan MRSA ST764. Rigorous surveillance of MRSA strains is imperative in Thailand to arrest its potential spread. [ABSTRACT FROM AUTHOR]

Aim: This study examined the effects of multimodal strategies on knowledge and practices in preventing multidrug‐resistant organism (MDRO) transmission among healthcare personnel (HCP), and to investigate MDRO transmission in two surgical intensive care units (SICUs). Design: A quasi‐experimental study with a one‐group pretest–posttest design. Methods: We recruited 62 HCP. Data were collected during 2017–2019. Multimodal strategies, including training, educational and reminder posters, an educational YouTube channel, champions and feedback, were used to enhance knowledge and practices. Data were analysed using Wilcoxon signed‐rank test and chi‐square test. Results: After the intervention, median knowledge scores increased from 16.0 to 17.0 (p =.001), and overall correct MDRO prevention practices increased from 76.6% to 94.0% (p <.001). The MDRO transmission rate decreased from 25% to 0% (p <.001). Conclusion: The findings indicate that multimodal strategies could enhance knowledge and practices for preventing MDRO transmission among HCP and could reduce the MDRO transmission rate in SICUs.

Existing data on the feasibility of human immunodeficiency virus (HIV) testing and counseling (HTC) and linkage to care among men who have sex with men (MSM) in hotspots are currently limited. A prospective study on active targeted HTC and linkage to care among MSM (≥18 years old) was conducted at a gay sauna in Thailand from November 2013 to October 2015. HIV risks and risk perception were evaluated through an anonymous survey. HIV testing with result notification and care appointment arrangement were provided on-site. Of the 358 participants; median age was 30 years; 206/358(58%) were at high risk for HIV acquisition; 148/358(41%) accepted HTC, all of whom either had prior negative HIV tests [98/148 (66%)] or had not known their HIV status [50/148 (34%)]. The three most common reasons for declining HTC were prior HIV testing within 6 months (48%), not ready (19%) and perceiving self as no risk (11%). Of the 262 moderate- and high-risk participants, 172 (66%) had false perception of low HIV risk which was significantly associated with declining HTC. Among the 148 participants undergoing HTC, 25 (17%) were HIV-infected. Having false perception of low risk (P = 0.004) and age <30 years (P = 0.02) were independently associated with HIV positivity. Only 14 of the 25 HIV-infected participants (56%) could be contacted after the result notification, of whom 12 (86%) had established HIV care and received immediate antiretroviral therapy. The active targeted HTC and facilitating care establishment was feasible among MSM attending the gay sauna but required strategies to improve accuracy of HIV-risk perception and linkage to care.

Background: HIV testing and counseling (HTC) with linkage to care after known infection are key components for HIV transmission prevention. This study was conducted to assess HTC uptake, HIV risk perception and linkage to care among Thai university students.Methods: An outreach HTC program was conducted in a large public university in Thailand from January 2013 to December 2014. The program consisted of brief HIV knowledge assessment, free HTC, HIV risk assessment and education provided by the healthcare personnel. Students were categorized into low, moderate and high-risk groups according to the pre-defined HIV risk characteristics.Results: One-thousand-eight-hundred-one students participated in the program, 494 (27 %) underwent HTC. Independent characteristics associated with no HTC uptake included female sex (P < 0.001), lower HIV knowledge score (P < 0.001), younger age (P < 0.001) and students from non-health science faculties (P = 0.02). Among the 494 students undergoing HTC, 141 (29 %) were categorized into moderate or high-risk group, of whom 45/141 (32 %) had false perception of low HIV risk. Being heterosexual was independently associated with false perception of low HIV risk (P = 0.04). The rate of new HIV infection diagnosis was 4/494 (0.8 %). Of these 4 HIV-infected students, 3 (75 %) were men who have sex with men and only 2 of the 4 students (50 %) showed up for HIV continuity care.Conclusions: An outreach HIV prevention program with HTC was feasible and beneficial in detecting HIV risk and infection among the university students. However, interventions to improve HTC uptake, HIV risk perception and linkage to care are needed. [ABSTRACT FROM AUTHOR]

Excess black-water flooding in central Thailand resulted in closure of several healthcare facilities in the Fall of 2011. Persons living with human immunodeficiency virus (HIV) infection were presumably at risk for interruption of antiretroviral therapy (ART), with consequent treatment failure. We conducted a retrospective cohort study of ART use among patients in care at a Thai HIV clinic that closed due to excess flood water. Among 217 patients on ART who had clinic appointments within the one-month interval before the floods through the one-month interval after the clinic re-opened, seven (3%) reported non-sustained ART access. Non-sustained ART access was independently associated with prior low self-reported ART adherence (P<0.001) and less than six-months duration on the ART regimen (P=0.03). Advanced ART receipt or procurement at other flood-free healthcare facilities were strategies associated with ART access. During a flood disaster, identification and close monitoring of at-risk patients, patient–staff communication, flood preparedness plans, “HIV care access for all” policies, and collaboration among patients, healthcare providers and the government are relevant issues within preparedness plans to optimize ART access.

A serologic study with simultaneous self-administered questionnaire regarding infection control (IC) practices and other risks of influenza A (H1N1) pdm09 (2009 H1N1) infection was performed approximately 1 month after the first outbreak among frontline healthcare professionals (HCPs). Of 256 HCPs, 33 (13%) were infected. Self-reported adherence to IC practices in >90% of exposure events was 82·1%, 73·8%, and 53·5% for use of hand hygiene, masks, and gloves, respectively. Visiting crowded public places during the outbreak was associated with acquiring infection (OR 3·1, P = 0·019). Amongst nurses, exposure to HCPs with influenza-like illness during the outbreak without wearing a mask was the only identified risk factor for infection (OR = 2·3, P = 0·039).

The article presents a cohort study of the risk factors for recombinant HIV infection in Thailand. It says that such infection was associated with high-risk sex behaviors, such as exchange of sex for money, having more than one sex partner within the prior 6 months, and decline in CD4 cell count. It suggests that HIV disease progression, safer sex practices, and vaccine development may predict recombinant HIV infection.

Fourteen (3%) of 495 Thai health care personnel were identified as having a serum sickness-like reaction in 2008 after receipt of inactivated influenza vaccine manufactured in Thailand. These health care personnel experienced fever, myalgia, centrifugal arthralgias, and injection site erythema. A history of allergic reactions to food or drugs (adjusted odds ratio, 5.9; 95% confidence interval, 1.54-25.4) was independently associated with a serum sickness-like reaction.

Background. The first phase of national surveillance for avian influenza (H5N1) human disease in Thailand occurred over a 4-month period that began on 1 December 2003. Subsequently, a nationally coordinated laboratory system (NCLS) for avian influenza (H5N1) was created to assess population-based surveillance, specimen procurement, case detection, and reporting at the national level. Methods. We conducted a pre- and postintervention study to evaluate the NCLS designed during the 6-week interval from 1 April through 15 May 2004. During the pre-NCLS period (1 December 2003 through 31 March 2004), 12 cases of human avian influenza (H5N1) were confirmed. During the post-NCLS period (16 May 2004 through 31 December 2006), interventions were implemented for human avian influenza (H5N1) surveillance, case detection, and expedited, computer-based reporting. Results. During the pre- and post-NCLS periods, 777 (85%) of 915 and 10,434 (95%) of 11,042 clinical respiratory specimens, respectively, were adequate for confirmatory testing (P < .001), the median time from procurement to results decreased from 17 days (range, 14-24 days) to 1.8 days (range, 0.25-4 days; P < .001), and the duration of specimen shipment decreased from 46.5 h to 21.1 h (P < .001). Thirteen cases of avian influenza (H5N1) were detected during the 31-month postintervention period. H5N1 reverse-transcriptase polymerase chain reaction and real-time reverse-transcriptase polymerase chain reaction sensitivity was 100% and specificity was 99.8%. Conclusions. The NCLS exemplifies a systematic approach to national surveillance for avian influenza A (H5N1). This NCLS program in Thailand serves as a model for human avian influenza (H5N1) preparedness that can be adopted or modified for use in other countries. [ABSTRACT FROM AUTHOR]

The Bangkok International Conference on Avian Influenza 2008 was organized by the National Center for Genetic Engineering and Biotechnology of Thailand. The Center has been playing an active role in the organization of research projects and knowledge management in preparation for an influenza pandemic since the beginning of the H5N1 avian influenza (AI) outbreak in the region in 2004. The timing of the conference, January 23rd, coincided with the 2004 announcement of the first outbreak in the country, marking the fourth year of widespread AI outbreaks in this region. In this 4-year period, progresses have been made scientifically and politically. Nevertheless, AI is still a major threat to us all. At the opening ceremony of the conference, Yongyuth Yuthavong, the Minister of Science and Technology of Thailand, emphasized that we are all together in the global village in this AI crisis and that we have to share information and materials and work together in the fight against this enemy of mankind.

Background. Ventilator-associated pneumonia (VAP) is considered to be an important cause of infection-related death and morbidity in intensive care units (ICUs). We sought to determine the long-term effect of an educational program to prevent VAP in a medical ICU (MICU). Methods. A 4-year controlled, prospective, quasi-experimental study was conducted in an MICU, surgical ICU (SICU), and coronary care unit (CCU) for 1 year before the intervention (period 1), 1 year after the intervention (period 2), and 2 follow-up years (period 3). The SICU and CCU served as control ICUs. The educational program involved respiratory therapists and nurses and included a self-study module with preintervention and postintervention assessments, lectures, fact sheets, and posters. Results. Before the intervention, there were 45 episodes of VAP (20.6 cases per 1000 ventilator-days) in the MICU, 11 (5.4 cases per 1000 ventilator-days) in the SICU, and 9 (4.4 cases per 1000 ventilator-days) in the CCU. After the intervention, the rate of VAP in the MICU decreased by 59% (to 8.5 cases per 1000 ventilator-days; P = .001) and remained stable in the SICU (5.6 cases per 1000 ventilator-days; P = .22) and CCU (4.8 cases per 1000 ventilator-days; P = .48). The rate of VAP in the MICU continued to decrease in period 3 (to 4.2 cases per 1000 ventilator-days; P = .07), and rates in the SICU and CCU remained unchanged. Compared with period 1, the mean duration of hospital stay in the MICU was reduced by 8.5 days in period 2 (P < .001) and by 8.9 days in period 3 (P < .001). The monthly hospital antibiotic costs of VAP treatment and the hospitalization cost for each patient in the MICU in periods 2 and 3 were also reduced by 45%-50% (P < .001) and 37%-45% (P < .001), respectively. Conclusions. A focused education intervention resulted in sustained reductions in the incidence of VAP, duration of hospital stay, cost of antibiotic therapy, and cost of hospitalization.

Background. We conducted a study to evaluate the impact of education and an antibiotic-control program on antibiotic-prescribing practices, antibiotic consumption, antimicrobial resistance, and cost of antibiotics in a tertiary care hospital in Thailand. Methods. A study of the year before and the year after the intervention was performed. Inpatient antibiotic prescriptions were prospectively observed. Demographic characteristics, hospital unit, indication for antibiotic prescription, appropriateness of antibiotic use, reasons for inappropriate antibiotic use, antibiotic consumption (i.e., the rate of antibiotic use), bacterial resistance, and antibiotic cost data were collected. Interventions included education, introduction of an antibiogram, use of antibiotic prescription forms, and prescribing controls. Results. After the intervention, there was a 24% reduction in the rate of antibiotic prescription (640 vs. 400 prescriptions/1000 admissions; P < .001). The incidence of inappropriate antibiotic use was significantly reduced (42% vs. 20%; P <.001). A sustained reduction in antibiotic use was observed (R² = 0.692; P<.001). Rates of use of third-generation cephalosporins (31 vs. 18 defined daily doses [DDDs]/1000 patient-days; P < .001) and glycopeptides (3.2 vs. 2.4 DDDs/1000 patient-days; P = .002) were significantly reduced. Rates of use of cefazolin (3.5 vs. 8.2 DDDs/1000 patient-days; P < .001) and fluoroquinolones (0.68 vs. 1.15 DDDs/1000 patient-days; P < .001) increased. There were no significant changes for other antibiotic classes. Significant reductions in the incidence of infections due to methicillin-resistant Staphylococcus aureus (48% vs. 33.5%; P < .001), extended- spectrum β-lactamase-producing Escherichia coli (33% vs. 21%; P < .001), extended-spectrum β-lactamase-producing Klebsiella pneumoniae (30% vs. 20%; P < .001), and third-generation cephalosporin-resistant Acinetobacter baumanii (27% vs. 19%; P < .001) were also observed. Total costs saving were US$32,231 during the study period. Conclusions. Education and an antibiotic-control program constituted an effective and cost-saving strategy to optimize antibiotic use in a tertiary care center in Thailand. [ABSTRACT FROM AUTHOR]

Influenza A (H5N1) is endemic in poultry across much of Southeast Asia, but limited information exists on the distinctive features of the few human cases. In Thailand, we instituted nationwide surveillance and tested respiratory specimens by polymerase chain reaction and viral isolation. From January 1 to March 31, 2004, we reviewed 610 reports and identified 12 confirmed and 21 suspected cases. AN 12 confirmed case-patients resided in villages that experienced abnormal chicken deaths, 9 lived in households whose backyard chickens died, and 8 reported direct contact with dead chickens. Seven were children <14 years of age. Fever preceded dyspnea by a median of 5 days, and lymphopenia significantly predicted acute respiratory distress syndrome development and death. Among hundreds of thousands of potential human cases of influenza A (H5N1) in Asia, a history of direct contact with sick poultry, young age, pneumonia and lymphopenia, and progression to acute respiratory distress syndrome should prompt specific laboratory testing for H5 influenza.

The antibiotic stewardship program (ASP) is a necessary part of febrile neutropenia (FN) treatment. Pharmacist-driven ASP is one of the meaningful approaches to improve the appropriateness of antibiotic usage. Our study aimed to determine role of the pharmacist in ASPs for FN patients. We prospectively studied at Thammasat University Hospital between August 2019 and April 2020. Our primary outcome was to compare the appropriate use of target antibiotics between the pharmacist-driven ASP group and the control group. The results showed 90 FN events in 66 patients. The choice of an appropriate antibiotic was significantly higher in the pharmacist-driven ASP group than the control group (88.9% vs. 51.1%, p < 0.001). Furthermore, there was greater appropriateness of the dosage regimen chosen as empirical therapy in the pharmacist-driven ASP group than in the control group (97.8% vs. 88.7%, p = 0.049) and proper duration of target antibiotics in documentation therapy (91.1% vs. 75.6%, p = 0.039). The multivariate analysis showed a pharmacist-driven ASP and infectious diseases consultation had a favorable impact on 30-day infectious diseases-related mortality in chemotherapy-induced FN patients (OR 0.058, 95%CI:0.005–0.655, p = 0.021). Our study demonstrated that pharmacist-driven ASPs could be a great opportunity to improve antibiotic appropriateness in FN patients. [ABSTRACT FROM AUTHOR]

Background: Men who have sex with men (MSM) are amongst populations at-risk for HIV acquisition in Thailand. In youth MSM (aged 15–24 years), the incidence of HIV infection has substantially increased. However, data on HIV risk, risk perception and HIV testing and counseling (HTC) uptake among youth MSM in hotspots are limited. Methods: A subanalysis of a prospective study among Thai MSM attending a gay sauna was conducted. HIV risk and risk perception were assessed by an anonymous survey. The MSM were categorized as having actual "low-risk", "moderate-risk" and "high-risk" for HIV acquisition based on the validated study risk categorization tool. HTC was provided on-site with result notification within 1 h. HIV care establishment appointment was arranged by the counselors for HIV-infected participants. Care engagement within 1 year of diagnosis was subsequently assessed. Results: There were 358 MSM participants; 87 (24%) were youth MSM. Comparing to other MSM, youth MSM had significantly higher median number of lifetime sexual partners [2 (IQR 1–9) vs. 1 (IQR 0–1); P < 0.001), were more-likely to ever exchange sex for money (44% vs. 9%; P < 0.001) and have sexual partner who exchanged sex for money (8% vs. 1%; P < 0.001). Rates of consistent condom use in the past 3 months for anal, oral and vaginal sexes were low and not significantly different between youth and other MSM (51% vs. 61%, 26% vs. 35% and 72% vs. 61%, respectively). By using the study risk categorization tool, there were 68 youth MSM with moderate or high-risk for HIV acquisition, of which 43 (63%) had false perception of low HIV risk. Youth MSM were more likely than other MSM to accept HTC [68% vs. 33%, P < 0.001)] and to be first-time testers (42% vs. 28%, P = 0.07). By HTC, the rates of HIV infection tended to be higher among youth MSM comparing to other MSM [14/59 (24%) vs. 11/89 (12%); P = 0.07]. Among the 14 youth MSM newly-diagnosed with HIV infection, only 6 (43%) showed-up for continuity care after 1-year follow-up. Conclusions: Youth MSM had substantial high HIV risk, false perception of low HIV risk and low rate of care engagement but demonstrated considerable rate of HTC uptake. Strategies to improve access to HTC, risk perception and linkage to care are needed for HIV prevention and management among the youth MSM. [ABSTRACT FROM AUTHOR]

Summary: The diagnosis of gnathostomiasis typically includes a triad of eosinophilia, migratory skin lesions, and exposure risk. The cutaneous manifestations are protean yet often involve intermittent migratory swellings and creeping skin eruptions with abscesses or nodules, which vary in onset and duration. We report the first case of gnathostomiasis presenting as fever and eosinophilia without cutaneous migratory and internal organ involvement. [ABSTRACT FROM AUTHOR]

Purpose To evaluate and compare antimicrobial stewardship program (ASP) guideline adherence (primary outcome) as well as length of stay, 30-day all-cause mortality, clinical cure, antimicrobial consumption, and incidence of multidrug-resistant (MDR) pathogens (secondary outcomes) between an infectious diseases (ID) pharmacist–led intervention group and a standard ASP group. Methods A quasi-experimental study was performed at Thammasat University Hospital between August 2019 and April 2020. Data including baseline characteristics and primary and secondary outcomes were collected from the electronic medical record by the ID pharmacist. Results The ASP guideline adherence in the ID pharmacist–led intervention group was significantly higher than in the standard ASP group (79% vs 56.6%; P < 0.001), especially with regard to appropriate indication (P < 0.001), dosage regimen (P = 0.005), and duration (P = 0.001). The acceptance rate of ID pharmacist recommendations was 81.8% (44/54). The most common key barriers to following recommendations were physician resistance (11/20; 55%) and high severity of disease in the patient (6/20; 30%). Compared to the standard ASP group, there was a trend toward clinical cure in the ID pharmacist–led intervention group (63.6% vs 56.1%; P = 0.127), while 30-day all-cause mortality (15.9% vs 1.5%; P = 0.344) and median length of stay (20 vs 18 days; P = 0.085) were similar in the 2 groups. Carbapenem (P = 0.042) and fosfomycin (P = 0.014) consumption declined in the ID pharmacist–led intervention group. A marginally significant decrease in the overall incidence of MDR pathogens was also observed in the ID pharmacist–led intervention group (coefficient, –5.93; P = 0.049). Conclusion Our study demonstrates that an ID pharmacist–led intervention can improve ASP guideline adherence and may reduce carbapenem consumption. [ABSTRACT FROM AUTHOR]

Evaluate and compare the efficacy and safety of molnupiravir and favipiravir in outpatients with mild to moderate COVID-19 and at risk of severe COVID-19. In an open-label, parallel-group, multicenter trial in Thailand, participants with moderate COVID-19 and at least one factor associated with severe COVID-19 were randomly assigned 1:1 to receive oral molnupiravir or oral favipiravir (standard of care). Phone calls for remote symptom assessment were made on Days 6, 15, and 29. Participants with worsening symptoms were instructed to return to the hospital. The primary endpoint was pulmonary involvement by Day 29, as evidenced by ≥2 of the following: dyspnea, oxygen saturation <92% or imaging. Nine hundred seventy-seven participants (487 molnupiravir, 490 favipiravir) were enrolled from 8 July 2022 to 19 January 2023. 98% had received ≥1 dose of COVID-19 vaccine and 83% ≥3 doses. By Day 29, pulmonary involvement occurred in 0% (0/483) in molnupiravir arm versus 1% (5/482) in favipiravir arm (−1.0%; Newcombe 95.2% CI: −2.4% to −0.0%; P = 0.021); all-cause death in 0% (0/483) and <1% (1/482); COVID-19 related hospitalization in <1% (1/483) and 1% (3/482); treatment-related adverse event in 1% (5/483) and 1% (4/486); and serious adverse event in 1% (4/483) and 1% (4/486). Favipiravir and molnupiravir had a similar efficacy and safety profile. Whether either of the two reduced the risk of complications during the omicron era in this population with a low risk of pulmonary involvement and a high vaccine coverage remains unclear. There were no differences in any of the safety endpoints. TCTR20230111009. [ABSTRACT FROM AUTHOR]

In this quasi-experimental study, implementing PX-UV to the standard environmental cleaning protocol was associated with a reduction in the overall incidence of multidrug-resistant (MDR) gram-negative organisms ( P = .01) and MDR Acinetobacter baumannii ( P = .001) in intervention intensive care units. However, the intervention did not reduce patient length of stay and 30-day mortality.

Background: Antimicrobial stewardship in Thailand has made major progress backed by a national strategic plan. The current study aimed to assess the antimicrobial stewardship program (ASP) composition, reach, and breadth, as well as urine culture stewardship in Thai hospitals., Methods: We sent an electronic survey to 100 Thai hospitals between February 1, 2021 and August 31, 2021. This hospital sample represented 20 hospitals in each of Thailand's 5 geographical regions., Results: The response rate was 100%. A total of 86 of 100 hospitals had an ASP. These were often multi-disciplinary in nature, with half including infectious disease-trained physicians and pharmacists, infection preventionists, and nursing staff. Urine culture stewardship protocols existed in 51% of hospitals., Conclusions: The national strategic plan in Thailand has allowed the country to stand up robust ASPs. Further research should examine the effectiveness of such programs and ways to expand them into other medical settings, like nursing homes, urgent care, and outpatient while continuing to grow telehealth and urine culture stewardship., (Copyright © 2023 Association for Professionals in Infection Control and Epidemiology, Inc.

In national surveys of infection preventionists in Israel (n = 15), the United States (n = 415), and Thailand (n = 100), we found that views of organizational culture track well with these countries' cultural dimension scores of power distance and individualism. Our findings highlight the importance of considering cultural dimensions when implementing infection prevention efforts., (Published by Elsevier Inc.)

Background: A 2014 study assessed infection prevention (IP) practices in Thai hospitals for catheter-associated urinary tract infection (CAUTI), central line-associated bloodstream infection (CLABSI), and ventilator-associated pneumonia (VAP). This study compares current IP practices to results obtained in 2014., Methods: Between February 1, 2021 and August 31, 2021, we resurveyed Thai hospitals regarding practices to prevent CAUTI, CLABSI, and VAP. We also assessed COVID-19 impact and healthcare worker burnout and coping strategies. We distributed 100 surveys to a convenience sample of infection preventionists., Results: Response rate: 100%. One-third (31%) of hospitals reported excellent leadership support for infection control (ie, responses of "good" or "excellent" to one survey question). Some prevention practices increased between 2014 vs 2021 (CAUTI: catheter reminder/stop-order/nurse-initiated discontinuation [50.0% vs 70.0%, P < .001]; condom catheters [36.3% vs 51.0%, P = .01]; ultrasound bladder scanner [4.7% vs 12.0%, P = .03]; CLABSI: chlorhexidine gluconate insertion site antisepsis [73.6% vs 85.0%, P = .03]; maximum sterile barrier precautions [63.2% vs 80.0%, P = .003]; VAP: selective digestive tract decontamination [26.9% vs 40.0%, P = .02]). Antimicrobial catheter use decreased since 2014 (10.4% vs 3.0%, P < .001). Many other practices remain suboptimal. COVID-19 challenges: staff shortages (71%), financial hardships (67%). Only 46% of infection preventionists felt safe working during COVID-19., Conclusions: More national strategic support is needed for IP programs to prevent CAUTI, CLABSI, VAP and healthcare worker well-being in Thailand during the COVID-19 pandemic., (Copyright © 2022.

Intensified infection prevention (IP) and health care personnel (HCP) vaccination programs could enhance HCP safety during COVID-19 pandemic. A multi-center survey regarding on intensified IP practices and vaccination uptake among HCP was performed. Working in the emergency medicine department was associated with wearing a double mask and face shield (P = .04). Despite having more confidence in care of COVID-19 patients, there was no significant improvement of intensified IP practices, COVID-19 and influenza vaccination programs among "high-risk" HCP., (Copyright © 2021 Association for Professionals in Infection Control and Epidemiology, Inc.

Mycobacterium scrofulaceum is an environmental mycobacterial species rarely reported to cause disseminated infection in adults. We report the case of a disseminated M. scrofulaceum infection in a 55-year-old nonhuman immunodeficiency virus-infected Thai man with anti-interferon-γ autoantibodies. The clinical signs of the infection improved after the induction regimen with amikacin, rifampicin, ethambutol, and clarithromycin, followed by the consolidation regimen with ethambutol, clarithromycin, and trimethoprim/sulfamethoxazole. Our review of previous reported cases of this infection indicates its association with immune deficiency, complex treatment, and a high rate of unfavorable outcomes., Competing Interests: None

Preoperative enteric screening for extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae was conducted in 360 patients prospectively observed for surgical site infection (SSI). ESBL colonization (adjusted odds ratio [aOR], 2.4) and dirty wound classification (aOR, 3.6) were associated with SSI; no association between carbapenem prophylaxis and reduction in SSI was detected.

Background: Cesarean surgical site infections (SSIs) can be prevented by proper preoperative antibiotic prophylaxis. Differences in antibiotic selection in clinical practice exist according to obstetricians' preferences despite clear guidelines on preoperative antibiotic prophylaxis. This study aimed to compare the efficacy of ampicillin and ceftriaxone in preventing cesarean SSIs., Methods: The observational prospective cohort study was conducted at a tertiary hospital in Thailand from 1 January 2007 to 31 December 2012. Propensity scores for ceftriaxone prophylaxis were calculated from potential influencing confounders. The cesarean SSI rates of the ceftriaxone group vs. those of the ampicillin prophylactic group were estimated by multilevel mixed-effects Poisson regression nested by propensity score., Results: Data of 4149 cesarean patients were collected. Among these, 911 patients received ceftriaxone whereas 3238 patients received ampicillin as preoperative antibiotic prophylaxis. The incidence of incisional SSIs was (0.1% vs. 1.2%; p  = 0.001) and organ space SSIs was (1.2% vs. 2.9%; p  = 0.003) in the ceftriaxone group compared with the ampicillin group. After adjusting for confounders, the rate ratios of incisional and organ/space SSIs in the ceftriaxone compared with the ampicillin group did not differ (RR, 0.23; 95% CI 0.03-1.78), and (RR, 1.62; 95% CI 0.83-3.18), respectively., Conclusion: These data indicate no difference exists between ampicillin and ceftriaxone to prevent SSIs after cesarean section. Ampicillin may be used as antibiotic prophylaxis in cesarean section., Competing Interests: This study was approved by the Research Ethics Committee 4, Faculty of Medicine, Chiang Mai University (reference no. 186/2013).Consent for publication is not applicable.The authors declare that they have no competing interests.Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.

A prospective study conducted in a Thai general practice clinic demonstrated a high prevalence (91.3%) of inappropriate empirical antibiotic use in women with uncomplicated cystitis and 42.6% Escherichia coli fluoroquinolone resistance. An annual update of antimicrobial resistance surveillance data of uropathogens may permit targeted treatment of patients in hospital care., (© The Author 2017.

Background: We evaluated the extent to which hospital characteristics, infection control practices, and compliance with prevention bundles impacted multidrug-resistant organism (MDRO) infections in Thai hospitals., Methods: From 1 January 2014 to 30 November 2014, we surveyed all Thai hospitals with an intensive care unit and ≥250 beds. Infection control practices for methicillin-resistant Staphylococcus aureus (MRSA) and multidrug-resistant Acinetobacter baumannii (MDR-AB) were assessed. Linear regression was used to examine associations between hospital characteristics and prevention bundle compliance and changes in MDRO infection rates., Results: A total of 212 of 245 (86.5%) eligible hospitals responded. Most hospitals regularly used several fundamental infection control practices for MRSA and MDR-AB (ie, contact precautions, private room/cohorting, hand hygiene, environmental cleaning, and antibiotic stewardship); advanced infection control practices (ie, active surveillance, chlorhexidine bathing, decolonization for MRSA, and hydrogen peroxide vaporizer for MDR-AB) were used less commonly. Facilities with ≥75% compliance with the MRSA prevention bundle experienced a 17.4% reduction in MRSA rates (P = .03). Although the presence of environmental cleaning services (41.3% reduction, P = .01) and a microbiology laboratory (82.8% reduction, P = .02) were among characteristics associated with decreases in MDR-AB rates, greater compliance with the MDR-AB prevention bundle did not lead to reductions in MDR-AB rates., Conclusions: Although fundamental MRSA and MDR-AB control practices are used regularly in most Thai hospitals, compliance with more comprehensive bundled prevention approaches is suboptimal. Improving compliance with bundled infection prevention approaches and promoting the integration of certain hospital factors into infection control efforts may help reduce MDRO infections in Thai hospitals., (© The Author 2017.

OBJECTIVE To evaluate the expected and treatment outcomes of Thai infectious disease physicians (IDPs) regarding carbapenem-resistant Acinetobacter baumannii (CRAB) ventilator-associated pneumonia (VAP) METHODS From June 1, 2014, to March 1, 2015, survey data regarding the expected and clinical success rates of CRAB VAP treatment were collected from all Thai IDPs. The expected success rate was defined as the expectation of clinical response after CRAB VAP treatment for the given case scenario. Clinical success rate was defined as the overall reported success rate of CRAB VAP treatment based on the clinical practice of each IDP. The expected and clinical success rates were divided into low (80%) categories and were then compared with standard clinical response rates archived in the existing literature. RESULTS Of 183 total Thai IDPs, 111 (60%) were enrolled in this study. The median expected and clinical success rates were 68% and 58%, respectively. Using multivariate analysis, we determined that working in a hospital that implemented the standard intervention combined with an intensified infection control (IC) intervention for CRAB (adjusted odds ratio [aOR], 3.01; 95% confidence interval [CI], 1.17-7.73; P=.02) was associated with standard and high expected rates (>60%). Being a board-certified IDP (aOR, 5.76; 95% CI, 2.16-15.37; P60%). We identified a significant correlation between expected and clinical success rates (r=0.58; P<.001). CONCLUSIONS Awareness of IC among IDPs can improve physicians' expected and clinical success rates for CRAB VAP treatment, and treatment experience impacts overall treatment success. Infect. Control Hosp. Epidemiol. 2015;37(1):61-69.

Mycobacterium haemophilum is an environmental organism that rarely causes infections in humans. We report a patient with acquired immunodeficiency syndrome who had central nervous system infection due to M. haemophilum. The diagnosis required brain tissue procurement and molecular identification method while the treatment outcome was unfavourable., (© The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.)

Background: Advanced source control (once-daily bathing and 4-times daily oral care with chlorhexidine aqueous solution) and thorough environmental cleaning were implemented in response to an increased incidence of colonization and infection with extremely drug-resistant (XDR) Acinetobacter baumannii in a Thai medical intensive care unit (MICU)., Methods: During the 12-month baseline period (P1), contact isolation, active surveillance for XDR A baumannii, cohorting of XDR A baumannii patients, twice-daily environmental cleaning with detergent-disinfectant, and antibiotic stewardship were implemented. In the 5.5-month intervention period (P2), additional measures were introduced. Sodium hypochlorite was substituted for detergent-disinfectant, and advanced source control was implemented. All interventions except cleaning with sodium hypochlorite were continued during the 12.5-month follow-up period (P3). Extensive flooding necessitating closure of the hospital for 2 months occurred between P2 and P3., Results: A total of 1,365 patients were studied. Compared with P1 (11.1 cases/1,000 patient-days), the rate of XDR A baumannii clinical isolates declined in P2 (1.74 cases/1,000 patient-days; P < .001) and further in P3 (0.69 cases/1,000 patient-days; P < .001). Compared with P1 (12.15 cases/1,000 patient-days), the rate of XDR A baumannii surveillance isolates also declined in P2 (2.11 cases/1,000 patient-days; P < .001) and P3 (0.98 cases/1,000 patient-days; P < .001). Incidence of nosocomial infections remained stable. Six patients developed chlorhexidine-induced rash (1.4/1,000 patient-days); 31 patients developed mucositis (17.1/1,000 patient-days)., Conclusions: These results support advanced source control and thorough environmental cleaning to limit colonization and infection with XDR A baumannii in MICUs in resource-limited settings., (Copyright © 2014 Association for Professionals in Infection Control and Epidemiology, Inc.

Pulmonary infection (P=.01) and an infectious diseases consultation (P=.04) were associated with carbapenem de-escalation; pulmonary infection and septic shock were associated with unsuccessful de-escalation. Successful de-escalation was associated with lower mortality (0% vs 23%; P<.001) and shorter duration of carbapenem use (4 vs 10 days; P ≤ .001).
