Establishing Quality Assurance for HIV-1 Rapid Test for Recent Infection in Thailand through the Utilization of Dried Tube Specimens.

The present study focuses on establishing the quality assurance of laboratories for recent infections (RTRI) in Thailand. We developed a cold-chain independent method, using fully characterized plasma obtained from the Thai Red Cross Society, and prepared as dried tube specimens (DTS). Twenty microliters of HIV-seronegative, recent, and long-term infected samples were aliquoted into individual tubes and dried at room temperature, 20-30 degrees Celsius, in a biosafety cabinet overnight to ensure optimal preservation. The DTS external quality control and external quality assessment were tested for homogeneity and stability following the ISO/Guide 35 guidelines. The DTS panels were distributed to 48 sites (FY 2022) and 27 sites (FY 2023) across 14 and 9 provinces, respectively, in Thailand. The results from participating laboratories were collected and evaluated for performance. The results were scored, and acceptable performance criteria were defined as the proportion of panels correctly tested, which was set at 100%. The satisfactory performance ranged from 96% to 100% and was not significantly different among the 13 health regions. The developed and implemented DTS panels can be used to monitor the quality of RTRI testing in Thailand.

A Web-Based, Respondent-Driven Sampling Survey Among Men Who Have Sex With Men (Kai Noi): Description of Methods and Characteristics.

BACKGROUND: Thailand's HIV epidemic is heavily concentrated among men who have sex with men (MSM), and surveillance efforts are mostly based on case surveillance and local biobehavioral surveys. OBJECTIVE: We piloted Kai Noi, a web-based respondent-driven sampling (RDS) survey among MSM. METHODS: We developed an application coded in PHP that facilitated all procedures and events typically used in an RDS office for use on the web, including e-coupon validation, eligibility screening, consent, interview, peer recruitment, e-coupon issuance, and compensation. All procedures were automated and e-coupon ID numbers were randomly generated. Participants' phone numbers were the principal means to detect and prevent duplicate enrollment. Sampling took place across Thailand; residents of Bangkok were also invited to attend 1 of 10 clinics for an HIV-related blood draw with additional compensation. RESULTS: Sampling took place from February to June 2022; seeds (21 at the start, 14 added later) were identified through banner ads, micromessaging, and in online chat rooms. Sampling reached all 6 regions and almost all provinces. Fraudulent (duplicate) enrollment using "borrowed" phone numbers was identified and led to the detection and invalidation of 318 survey records. A further 106 participants did not pass an attention filter question (asking recruits to select a specific categorical response) and were excluded from data analysis, leading to a final data set of 1643 valid participants. Only one record showed signs of straightlining (identical adjacent responses). None of the Bangkok respondents presented for a blood draw. CONCLUSIONS: We successfully developed an application to implement web-based RDS among MSM across Thailand. Measures to minimize, detect, and eliminate fraudulent survey enrollment are imperative in web-based surveys offering compensation. Efforts to improve biomarker uptake are needed to fully tap the potential of web-based sampling and data collection.

Frequency and mortality rate following antimicrobial-resistant bloodstream infections in tertiary-care hospitals compared with secondary-care hospitals.

There are few studies comparing proportion, frequency, mortality and mortality rate following antimicrobial-resistant (AMR) infections between tertiary-care hospitals (TCHs) and secondary-care hospitals (SCHs) in low and middle-income countries (LMICs) to inform intervention strategies. The aim of this study is to demonstrate the utility of an offline tool to generate AMR reports and data for a secondary data analysis. We conducted a secondary-data analysis on a retrospective, multicentre data of hospitalised patients in Thailand. Routinely collected microbiology and hospital admission data of 2012 to 2015, from 15 TCHs and 34 SCHs were analysed using the AMASS v2.0 (www.amass.website). We then compared the burden of AMR bloodstream infections (BSI) between those TCHs and SCHs. Of 19,665 patients with AMR BSI caused by pathogens under evaluation, 10,858 (55.2%) and 8,807 (44.8%) were classified as community-origin and hospital-origin BSI, respectively. The burden of AMR BSI was considerably different between TCHs and SCHs, particularly of hospital-origin AMR BSI. The frequencies of hospital-origin AMR BSI per 100,000 patient-days at risk in TCHs were about twice that in SCHs for most pathogens under evaluation (for carbapenem-resistant Acinetobacter baumannii [CRAB]: 18.6 vs. 7.0, incidence rate ratio 2.77; 95%CI 1.72-4.43, p<0.001; for carbapenem-resistant Pseudomonas aeruginosa [CRPA]: 3.8 vs. 2.0, p = 0.0073; third-generation cephalosporin resistant Escherichia coli [3GCREC]: 12.1 vs. 7.0, p<0.001; third-generation cephalosporin resistant Klebsiella pneumoniae [3GCRKP]: 12.2 vs. 5.4, p<0.001; carbapenem-resistant K. pneumoniae [CRKP]: 1.6 vs. 0.7, p = 0.045; and methicillin-resistant Staphylococcus aureus [MRSA]: 5.1 vs. 2.5, p = 0.0091). All-cause in-hospital mortality (%) following hospital-origin AMR BSI was not significantly different between TCHs and SCHs (all p>0.20). Due to the higher frequencies, all-cause in-hospital mortality rates following hospital-origin AMR BSI per 100,000 patient-days at risk were considerably higher in TCHs for most pathogens (for CRAB: 10.2 vs. 3.6,mortality rate ratio 2.77; 95%CI 1.71 to 4.48, p<0.001; CRPA: 1.6 vs. 0.8; p = 0.020; 3GCREC: 4.0 vs. 2.4, p = 0.009; 3GCRKP, 4.0 vs. 1.8, p<0.001; CRKP: 0.8 vs. 0.3, p = 0.042; and MRSA: 2.3 vs. 1.1, p = 0.023). In conclusion, the burden of AMR infections in some LMICs might differ by hospital type and size. In those countries, activities and resources for antimicrobial stewardship and infection control programs might need to be tailored based on hospital setting. The frequency and in-hospital mortality rate of hospital-origin AMR BSI are important indicators and should be routinely measured to monitor the burden of AMR in every hospital with microbiology laboratories in LMICs.

Thailand's national strategic plan on antimicrobial resistance: progress and challenges.

Antimicrobial resistance is a serious threat that affects all countries. The Global Action Plan on antimicrobial resistance and the United Nations Political Declaration on antimicrobial resistance set standards for countries to resolve antimicrobial resistance challenges under the One Health approach. We assess progress and challenges in implementing Thailand's national strategic plan on antimicrobial resistance 2017-2022, discuss interim outcomes and share lessons learnt. Major progress includes: establishing a national governance mechanism that leads high-impact policy on antimicrobial resistance and consolidates actions and multisectoral collaboration; creating a monitoring system and platform to track implementation of the strategic plan; and converting strategies of the strategic plan into actions such as controlling the distribution and use of antimicrobials in humans and animals. Interim results indicate that antimicrobial consumption in animals has nearly halved (exceeding the national goal of a 30% reduction) whereas other goals have not yet reached their targets. We have learnt that elevating antimicrobial resistance to high-level visibility and establishing a national governance mechanism is an important first step, and a monitoring and evaluation system should be developed in parallel with implementation. Securing funds is crucial. Policy coherence is needed to avoid duplication of actions. Highly ambitious goals, although yet to be achieved, can advance actions beyond expectations. Political commitment and collaboration across different sectors will continue to play important roles but might not be sustained without a well-designed governance structure to support long-term actions to address antimicrobial resistance.

La résistance aux antimicrobiens fait peser une sérieuse menace sur la planète tout entière. Le Plan d'action mondial pour combattre la résistance aux antimicrobiens ainsi que la Déclaration politique des Nations Unies sur la résistance aux agents antimicrobiens ont défini des normes pour les pays, afin qu'ils puissent faire face aux enjeux liés à la résistance aux antimicrobiens selon l'approche «One Health¼. Nous avons évalué les progrès et défis de la mise en œuvre du plan stratégique national de la Thaïlande en la matière pour 2017­2022, mais aussi discuté des résultats provisoires et partagé les enseignements tirés. Parmi les principaux progrès accomplis figurent l'établissement d'un mécanisme de gouvernance national pour mener une politique à impact élevé sur la résistance aux antimicrobiens, renforcer les actions et favoriser la collaboration intersectorielle; la création d'un système de surveillance et d'une plateforme pour suivre la mise en œuvre du plan stratégique; et enfin, la conversion des stratégies du plan en actions telles que le contrôle de la distribution et de l'usage des antimicrobiens chez les humains et les animaux. Les résultats provisoires indiquent que la consommation d'antimicrobiens chez les animaux a diminué de moitié (ce qui est supérieur à l'objectif national d'une réduction de 30%), tandis que les autres objectifs n'ont pas encore été atteints. Nous avons constaté qu'accroître la visibilité de la résistance aux antimicrobiens et instaurer un mécanisme de gouvernance national constituaient des étapes cruciales, et qu'un système de surveillance et d'évaluation devait être développé parallèlement à la mise en œuvre. L'obtention de financements est elle aussi essentielle. Une politique cohérente est nécessaire pour éviter de multiplier les actions similaires. Fixer des objectifs très ambitieux, même s'ils ne sont pas encore atteints, permet en outre de faire progresser les actions au-delà des attentes. Enfin, l'engagement politique et la collaboration entre différents secteurs continueront à jouer un rôle prépondérant, mais ne pourront peut-être pas se poursuivre sans une structure de gouvernance bien conçue, capable de soutenir des actions à long terme visant à remédier à la résistance aux antimicrobiens.

La resistencia a los antimicrobianos es una grave amenaza que afecta a todos los países. El Plan de Acción Mundial sobre la resistencia a los antimicrobianos y la Declaración Política de las Naciones Unidas sobre la resistencia a los antimicrobianos establecen normas para que los países resuelvan los problemas de resistencia a los antimicrobianos en el marco del enfoque «Una única salud¼. Evaluamos los avances y los desafíos en la aplicación del plan estratégico nacional de Tailandia sobre la resistencia a los antimicrobianos 2017-2022, analizamos los resultados provisionales y compartimos las lecciones aprendidas. Entre los principales avances se encuentran: el establecimiento de un mecanismo de gobernanza nacional que lidera la política de alto impacto sobre la resistencia a los antimicrobianos y consolida las acciones y la colaboración multisectorial; la creación de un sistema de seguimiento y una plataforma para seguir la aplicación del plan estratégico; y la conversión de las estrategias del plan estratégico en acciones como el control de la distribución y el uso de antimicrobianos en humanos y animales. Los resultados provisionales indican que el consumo de antimicrobianos en animales se ha reducido casi a la mitad (superando el objetivo nacional de una reducción del 30 %), mientras que otros objetivos aún no han alcanzado sus metas. Hemos aprendido que elevar la resistencia a los antimicrobianos a una visibilidad de alto nivel y establecer un mecanismo de gobernanza nacional es un primer paso importante, y que debe desarrollarse un sistema de seguimiento y evaluación en paralelo a la implementación. Asegurar los fondos es crucial. La coherencia política es necesaria para evitar la duplicación de acciones. Unos objetivos muy ambiciosos, aunque todavía no se hayan alcanzado, pueden hacer avanzar las acciones más allá de las expectativas. El compromiso político y la colaboración entre los distintos sectores seguirán desempeñando un papel importante, pero podrían no mantenerse sin una estructura de gobernanza bien diseñada que apoye las acciones a largo plazo para hacer frente a la resistencia a los antimicrobianos.

Enhanced surveillance for severe pneumonia, Thailand 2010-2015.

BACKGROUND: The etiology of severe pneumonia is frequently not identified by routine disease surveillance in Thailand. Since 2010, the Thailand Ministry of Public Health (MOPH) and US CDC have conducted surveillance to detect known and new etiologies of severe pneumonia. METHODS: Surveillance for severe community-acquired pneumonia was initiated in December 2010 among 30 hospitals in 17 provinces covering all regions of Thailand. Interlinked clinical, laboratory, pathological and epidemiological components of the network were created with specialized guidelines for each to aid case investigation and notification. Severe pneumonia was defined as chest-radiograph confirmed pneumonia of unknown etiology in a patient hospitalized ≤48 h and requiring intubation with ventilator support or who died within 48 h after hospitalization; patients with underlying chronic pulmonary or neurological disease were excluded. Respiratory and pathological specimens were tested by reverse transcription polymerase chain reaction for nine viruses, including Middle East Respiratory Syndrome Coronavirus (MERS-CoV), and 14 bacteria. Cases were reported via a secure web-based system. RESULTS: Of specimens from 972 cases available for testing during December 2010 through December 2015, 589 (60.6%) had a potential etiology identified; 399 (67.8%) were from children aged < 5 years. At least one viral agent was detected in 394 (40.5%) cases, with the most common of single vial pathogen detected being respiratory syncytial virus (RSV) (110/589, 18.7%) especially in children under 5 years. Bacterial pathogens were detected in 341 cases of which 67 cases had apparent mixed infections. The system added MERS-CoV testing in September 2012 as part of Thailand's outbreak preparedness; no cases were identified from the 767 samples tested. CONCLUSIONS: Enhanced surveillance improved the understanding of the etiology of severe pneumonia cases and improved the MOPH's preparedness and response capacity for emerging respiratory pathogens in Thailand thereby enhanced global health security. Guidelines for investigation of severe pneumonia from this project were incorporated into surveillance and research activities within Thailand and shared for adaption by other countries.

Viral etiologies of influenza-like illness and severe acute respiratory infections in Thailand.

BACKGROUND: Information on the burden, characteristics and seasonality of non-influenza respiratory viruses is limited in tropical countries. OBJECTIVES: Describe the epidemiology of selected non-influenza respiratory viruses in Thailand between June 2010 and May 2014 using a sentinel surveillance platform established for influenza. METHODS: Patients with influenza-like illness (ILI; history of fever or documented temperature ≥38°C, cough, not requiring hospitalization) or severe acute respiratory infection (SARI; history of fever or documented temperature ≥38°C, cough, onset <10 days, requiring hospitalization) were enrolled from 10 sites. Throat swabs were tested for influenza viruses, respiratory syncytial virus (RSV), metapneumovirus (MPV), parainfluenza viruses (PIV) 1-3, and adenoviruses by polymerase chain reaction (PCR) or real-time reverse transcriptase-PCR. RESULTS: We screened 15 369 persons with acute respiratory infections and enrolled 8106 cases of ILI (5069 cases <15 years old) and 1754 cases of SARI (1404 cases <15 years old). Among ILI cases <15 years old, influenza viruses (1173, 23%), RSV (447, 9%), and adenoviruses (430, 8%) were the most frequently identified respiratory viruses tested, while for SARI cases <15 years old, RSV (196, 14%) influenza (157, 11%) and adenoviruses (90, 6%) were the most common. The RSV season significantly overlapped the larger influenza season from July to November in Thailand. CONCLUSIONS: The global expansion of influenza sentinel surveillance provides an opportunity to gather information on the characteristics of cases positive for non-influenza respiratory viruses, particularly seasonality, although adjustments to case definitions may be required.

An Assessment of Epidemiology Capacity in a One Health Team at the Provincial Level in Thailand.

A multi-sectoral core epidemiology capacity assessment was conducted in provinces that implemented One Health services in order to assess the efficacy of a One Health approach in Thailand. In order to conduct the assessment, four provinces were randomly selected as a study group from a total of 19 Thai provinces that are currently using a One Health approach. As a control group, four additional provinces that never implemented a One Health approach were also sampled. The provincial officers were interviewed on the epidemiologic capacity of their respective provinces. The average score of epidemiologic capacity in the provinces implementing the One Health approach was 66.45%, while the provinces that did not implement this approach earned a score of 54.61%. The epidemiologic capacity of surveillance systems in provinces that utilized the One Health approach earned higher scores in comparison to provinces that did not implement the approach (75.00% vs. 53.13%, p-value 0.13). Although none of the capacity evaluations showed significant differences between the two groups, we found evidence that provinces implementing the One Health approach gained higher scores in both surveillance and outbreak investigation capacities. This may be explained by more efficient capacity when using a One Health approach, specifically in preventing, protecting, and responding to threats in local communities.

Influenza viruses in Thailand: 7 years of sentinel surveillance data, 2004-2010.

BACKGROUND: The re-emergence of avian influenza A (H5N1) in 2004 and the pandemic of influenza A (H1N1) in 2009 highlight the need for routine surveillance systems to monitor influenza viruses, particularly in Southeast Asia where H5N1 is endemic in poultry. In 2004, the Thai National Institute of Health, in collaboration with the U.S. Centers for Disease Control and Prevention, established influenza sentinel surveillance throughout Thailand. OBJECTIVES: To review routine epidemiologic and virologic surveillance for influenza viruses for public health action. METHODS: Throat swabs from persons with influenza-like illness and severe acute respiratory illness were collected at 11 sentinel sites during 2004-2010. Influenza viruses were identified using the standard protocol for polymerase chain reaction. Viruses were cultured and identified by immunofluorescence assay; strains were identified by hemagglutination inhibition assay. Data were analyzed to describe frequency, seasonality, and distribution of circulating strains. RESULTS: Of the 19,457 throat swabs, 3967 (20%) were positive for influenza viruses: 2663 (67%) were influenza A and able to be subtyped [21% H1N1, 25% H3N2, 21% pandemic (pdm) H1N1] and 1304 (33%) were influenza B. During 2009-2010, the surveillance system detected three waves of pdm H1N1. Influenza annually presents two peaks, a major peak during the rainy season (June-August) and a minor peak in winter (October-February). CONCLUSIONS: These data suggest that March-April may be the most appropriate months for seasonal influenza vaccination in Thailand. This system provides a robust profile of the epidemiology of influenza viruses in Thailand and has proven useful for public health planning.
