Exploring indoor and outdoor dust as a potential tool for detection and monitoring of COVID-19 transmission

This study investigated the potential of using SARS-CoV-2 viral concentrations in dust as an additional surveillance tool for early detection and monitoring of COVID-19 transmission. Dust samples were collected from 8 public locations in 16 districts of Bangkok, Thailand, from June to August 2021. SARS-CoV-2 RNA concentrations in dust were quantified, and their correlation with community case incidence was assessed. Our findings revealed a positive correlation between viral concentrations detected in dust and the relative risk of COVID-19. The highest risk was observed with no delay (0-day lag), and this risk gradually decreased as the lag time increased. We observed an overall decline in viral concentrations in public places during lockdown, closely associated with reduced human mobility. The effective reproduction number for COVID-19 transmission remained above one throughout the study period, suggesting that transmission may persist in locations beyond public areas even after the lockdown measures were in place

Alternative Leadership in Flexible Surge Capacity—The Perceived Impact of Tabletop Simulation Exercises on Thai Emergency Physicians Capability to Manage a Major Incident

Flexible surge capacity aims to activate and utilize other resources than normally are surged in a community during the primary and secondary surge capacity. The presence of alternative leadership, skilled and knowledgeable in hospital and prehospital emergency management, is invaluable. Thai emergency physicians work at both levels, emphasizing their important role in emergency management of any source in a disaster-prone country. We aimed to investigate Thai emergency physicians’ ability in terms of knowledge and preparedness to manage potential emergencies using tabletop simulation exercises. Using an established method for training collaboration, two training courses were arranged for over 50 Thai emergency physicians, who were divided into three teams of prehospital, hospital, and incident command groups. Three scenarios of a terror attack along with a bomb explosion, riot, and shooting, and high building fire were presented, and the participants’ performance was evaluated regarding their preparedness, response and gained knowledge. Two senior observers followed the leadership characteristic in particular. Thai physicians’ perceived ability in command and control, communication, collaboration, coordination, and situation assessment improved in all groups systematically. New perspectives and innovative measures were presented by participants, which improved the overall management on the final day. Tabletop simulation exercise increased the perceived ability, knowledge, and attitude of Thai emergency physicians in managing major incidents and disasters. It also enabled them to lead emergency management in a situation when alternative leadership is a necessity as part of the concept of a flexible surge capacity response system

Regional Flexible Surge Capacity – A Flexible Response System

Surge capacity is the ability to manage the increased influx of critically ill or injured patients during a sudden onset crisis. During such an event, all ordinary resources are activated and used in a systematic, structured, and planned way to cope with the situation. There are, however, occasions where conventional healthcare means are insufficient, and additional resources must be summoned. In such an event, the activation of existing capabilities within community resources can increase regional surge capacity in a flexible manner. These additional resources together represent the concept of Flexible Surge Capacity. This study aims to investigate the possibility of establishing a Flexible Surge Capacity response system to emergencies by examining the main components of surge capacity (Staff, Stuff, Structure, System) within facilities of interest present in the Western Region of Sweden. Through a mixed-method and use of (A) questionnaires and (B) semi-structured key-informant interviews, data was collected from potential alternative care facilities to determine capacities and capabilities and barriers and limitations as well as interest to be included in a flexible surge capacity response system. Both interest and ability were found in the investigated primary healthcare centers, veterinary and dental clinics, schools, and sports and hotel facilities to participate in such a system, either by receiving resources and/or drills and exercises. Barriers limiting the potential participation in this response system consisted of a varying lack of space, beds, healthcare materials, and competencies along with a need for clear organizational structure and medical responsibility. These results indicate that the concept of flexible surge capacity is a feasible approach to emergency management. Educational initiatives, drills and exercises, layperson empowerment, organizational and legal changes and sufficient funding are needed to realize the concept

The feasibility of implementing the flexible surge capacity concept in bangkok: Willing participants and educational gaps

The management of emergencies consists of a chain of actions with the support of staff, stuff, structure, and system, i.e., surge capacity. However, whenever the needs exceed the present resources, there should be flexibility in the system to employ other resources within communities, i.e., flexible surge capacity (FSC). This study aimed to investigate the possibility of creating alternative care facilities (ACFs) to relieve hospitals in Bangkok, Thailand. Using a Swedish questionnaire, quantitative data were compiled from facilities of interest and were completed with qualitative data obtained from interviews with key informants. Increasing interest to take part in a FSC system was identified among those interviewed. All medical facilities indicated an interest in offering minor treatments, while a select few expressed interest in offering psychosocial support or patient stabilization before transport to major hospitals and minor operations. The non-medical facilities interviewed proposed to serve food and provide spaces for the housing of victims. The lack of knowledge and scarcity of medical instruments and materials were some of the barriers to implementing the FSC response system. Despite some shortcomings, FSC seems to be applicable in Thailand. There is a need for educational initiatives, as well as a financial contingency to grant the sustainability of FSC

Optimal chest compression position for cardiopulmonary resuscitation determined by computed tomography image: retrospective cross-sectional analysis

Abstract The objective of this study was to determine the height of optimal hand position for chest compression during adult cardiopulmonary resuscitation (CPR) from the tip of the sternal xiphoid process (TOX) along with the relative heights of the left ventricular outflow tract (LVOT) and abdominal organs among the Thai population. The retrospective cross-sectional study was conducted through a review of medical records and contrast-enhanced chest computed tomography. The total of 204 Thai patients without obvious chest deformity at Ramathibodi Hospital from January to June 2018 was included as part of a multi-regional study. The heights of the level of maximal LV width (LVmax), LOVT, top of liver and stomach with respect to TOX were measured on midline sagittal image. Mean age and body mass index (BMI) were 59.5 years and 23.9 kg/m2, respectively. One hundred and one subjects (49.5%) had pulmonary diseases. Mean height of the LVmax from TOX was 37.7 mm, corresponding to 20% of the sternal length (SL) in the inspiration arm raised position (IAR). The adjusted height of LVmax from TOX in the expiration arm-down position (EAD) was 89.7 mm (48% of SL). The inter-nipple line was at 84.5 mm (45.1% of SL) from TOX on IAR. Among 178 and 109 subjects whose uppermost part of the liver and stomach were above TOX, 80.4% and 94.5% were located within the lower half of the sternum, respectively. The adjusted optimal hand position for chest compression during CPR was at approximately 89.7 mm from TOX in EAD (48% of SL). The hand position at the upper part of the lower half of the sternum is closest to the adjusted LVmax and has a better chance to avoid compression of intraabdominal organs. Trial registration This trial was retrospectively registered on 2 February 2023 in the Thai Clinical Trial Registry, identification number TCTR 20230202006

The impact of the three-level collaboration exercise on collaboration and leadership during scenario-based hospital evacuation exercises using flexible surge capacity concept: a mixed method cross-sectional study

Abstract Background Hospitals play a crucial role in responding to disasters and public health emergencies. However, they are also vulnerable to threats such as fire or flooding and can fail to respond or evacuate adequately due to unpreparedness and lack of evacuation measures. The United Nations Office for Disaster Risk Reduction has emphasised the importance of partnerships and capacity building in disaster response. One effective way to improve and develop disaster response is through exercises that focus on collaboration and leadership. This study aimed to examine the effectiveness of using the 3-level collaboration (3LC) exercise in developing collaboration and leadership in districts in Thailand, using the concept of flexible surge capacity (FSC) and its collaborative tool during a hospital evacuation simulation. Methods A mixed-method cross-sectional study was conducted with 40 participants recruited from disaster-response organisations and communities. The data from several scenario-based simulations were collected according to the collaborative elements (Command and control, Safety, Communication, Assessment, Triage, Treatment, Transport), in the disaster response education, “Major Incident Medical Management and Support” using self-evaluation survey pre- and post-exercises, and direct observation. Results The 3LC exercise effectively facilitated participants to gain a mutual understanding of collaboration, leadership, and individual and organisational flexibility. The exercise also identified gaps in communication and the utilisation of available resources. Additionally, the importance of early community engagement was highlighted to build up a flexible surge capacity during hospital evacuation preparedness. Conclusions the 3LC exercise is valuable for improving leadership skills and multiagency collaboration by incorporating the collaborative factors of Flexible Surge Capacity concept in hospital evacuation preparedness

Differences in Ethical Viewpoints among Civilian–Military Populations: A Survey among Practitioners in Two European Countries, Based on a Systematic Literature Review

Civilian–military collaboration in humanitarian crises has been encouraged globally; however, little is known about their diverse ethical viewpoints towards challenging and critical situations, which may cause difficulties in the partnership, and influence the outcomes of their mutual activities. The aim of this study was to identify the diversity of viewpoints and ethical decision-making during exceptional circumstances among civilian and military populations from two different countries, each with diverse background and healthcare organization structures. Possible scenarios, based on a systematic review of the literature, were introduced to Swedish and Polish civilian and military healthcare providers. Variations in the participants’ viewpoints and approaches to ethical decision-making were analyzed according to their characteristics, organizational belonging, and nationality. There were differences between both populations but also within the military and civilian groups, respectively. One significant factor influencing ethical viewpoints was participants’ nationality. Differences in ethical viewpoints between multiagency organizations should be considered in planning and implementation of future transdisciplinary and international collaboration in disaster and emergency management. Further studies and renewed educational initiatives are necessary to validate these differences and to navigate civilian–military as well as other multinational partnerships
