Application of Incident Command Structure to clinical trial management in the academic setting: principles and lessons learned

Background Clinical trial success depends on appropriate management, but practical guidance to trial organisation and planning is lacking. The Incident Command System (ICS) is the ‘gold standard’ management system developed for managing diverse operations in major incident and public health arenas. It enables effective and flexible management through integration of personnel, procedures, resources, and communications within a common hierarchical organisational structure. Conventional ICS organisation consists of five function modules: Command, Planning, Operations, Logistics, and Finance/Administration. Large clinical trials will require a separate Regulatory Administrative arm, and an Information arm, consisting of dedicated data management and information technology staff. We applied ICS principles to organisation and management of the Prehospital Use of Plasma in Traumatic Haemorrhage (PUPTH) trial. This trial was a multidepartmental, multiagency, randomised clinical trial investigating prehospital administration of thawed plasma on mortality and coagulation response in severely injured trauma patients. We describe the ICS system as it would apply to large clinical trials in general, and the benefits, barriers, and lessons learned in utilising ICS principles to reorganise and coordinate the PUPTH trial. Results Without a formal trial management structure, early stages of the trial were characterised by inertia and organisational confusion. Implementing ICS improved organisation, coordination, and communication between multiple agencies and service groups, and greatly streamlined regulatory compliance administration. However, unfamiliarity of clinicians with ICS culture, conflicting resource allocation priorities, and communication bottlenecks were significant barriers. Conclusions ICS is a flexible and powerful organisational tool for managing large complex clinical trials. However, for successful implementation the cultural, psychological, and social environment of trial participants must be accounted for, and personnel need to be educated in the basics of ICS

POLICY DEPLOYMENT FOR CONTINUOUS IMPROVEMENT IN PUBLIC HOSPITALS. From Kaizen Initiatives to a Kaizen Initiative Program: an action research

Purpose. Although kaizen methodology is increasingly applied and investigated in healthcare, most of the current literature describes successful kaizen initiatives and report their technical outcomes (e.g. Dickson et al., 2009; Laganga, 2011). Aspects related to the deployment of the kaizen approach across healthcare organizations are often neglected by the scholars. Thus, this thesis aims at filling this gap by developing and testing a theoretical framework to understand how the continuous improvement approach could be adopted and adapted to a public hospital and what features should be considered as key drivers of a successful implementation. In particular, this study uses a policy deployment perspective to investigate the linkage between decisions at the strategic level within healthcare organizations and those regarding the implementation of a set of kaizen initiatives over time (Kaizen Initiative Program \u2013 KIP). Design/Methodology/Approach. This study uses the action research methodology to develop theoretical and practical insights from a complex endeavour as kaizen implementation in public hospitals. The research is divided in four main cycles: Design; Training; Kaizen (Implementation and Monitoring) and Evaluation. Each cycle includes: a pre-step for understanding context and purpose; a six main-step stage (to gather, feedback and analyse data, to plan, implement and evaluate actions) and a meta-step (to monitor) (Coughlan and Coghlan, 2002). The researcher played an active role and adopted the process consultation model to support the healthcare professionals engaged. Thus, the researcher could investigate in real time what characterized a continuous improvement program and how it has been deployed across the hospitals involved. Findings. By investigating how the continuous improvement approach is implemented in public hospitals this study describes and discusses the practical problems addressed and difficulties emerging over time at both strategical and operational level, and at team and organisational level during the action research. In particular, this study provides: 1) a tested framework for applying a KI Program at both organisational and system level (e.g., regional/healthcare district); 2) the key features/practices of the KI Program (what) and their sequence for a successful implementation (when); 3) the successful deployment modalities of the KI Program (how) to properly select the kaizen teams and initiatives (e.g., the periodic briefings between the managers from the strategic level and the kaizen teams). Practical implications. Results provide a structured framework for healthcare practitioners and managers who are interested in successfully launching and sustaining a KI Program. This framework could help hospital managers to link the strategic level decisions with continuous improvement actions at the operational level, avoiding the only use of bottom-up and pop-corn initiatives. Originality. The research proposes a tested framework emerging from the action research for successfully selecting kaizen initiatives that are linked to the strategic objectives of healthcare organizations. Differently from the existing kaizen literature, this research engaged seven different and independent hospitals that have been performing their first kaizen experience simultaneously and which belong to the same regional healthcare system and are led by a unique regional administration office.

A distributed simulation methodology for large-scale hybrid modelling and simulation of emergency medical services

This thesis was submitted for the award of Doctor of Philosophy and was awarded by Brunel University LondonHealthcare systems are traditionally characterised by complexity and heterogeneity. With the continuous increase in size and shrinkage of available resources, the healthcare sector faces the challenge of delivering high quality services with fewer resources. Healthcare organisations cannot be seen in isolation since the services of one such affects the performance of other healthcare organisations. Efficient management and forward planning, not only locally but rather across the whole system, could support healthcare sector to overcome the challenges. An example of closely interwoven organisations within the healthcare sector is the emergency medical services (EMS). EMS operate in a region and usually consist of one ambulance service and the available accident and emergency (A&E) departments within the coverage area. EMS provide, mainly, pre-hospital treatment and transport to the appropriate A&E units. The life-critical nature of EMS demands continuous systems improvement practices. Modelling and Simulation (M&S) has been used to analyse either the ambulance services or the A&E departments. However, the size and complexity of EMS systems constitute the conventional M&S techniques inadequate to model the system as a whole. This research adopts the approach of distributed simulation to model all the EMS components as individual and composable simulations that are able to run as standalone simulation, as well as federates in a distributed simulation (DS) model. Moreover, the hybrid approach connects agent-based simulation (ABS) and discrete event simulation (DES) models in order to accommodate the heterogeneity of the EMS components. The proposed FIELDS Framework for Integrated EMS Large-scale Distributed Simulation supports the re-use of existing, heterogeneous models that can be linked with the High Level Architecture (HLA) protocol for distributed simulation in order to compose large-scale simulation models. Based on FIELDS, a prototype ABS-DES distributed simulation EMS model was developed based on the London EMS. Experiments were conducted with the model and the system was tested in terms of performance and scalability measures to assess the feasibility of the proposed approach. The yielded results indicate that it is feasible to develop hybrid DS models of EMS that enables holistic analysis of the system and support model re-use. The main contributions of this thesis is a distributed simulation methodology that derived along the process of conducting this project, the FIELDS framework for hybrid EMS distributed simulation studies that support re-use of existing simulation models, and a prototype distributed simulation model that can be potentially used as a tool for EMS analysis and improvement.MATCH Programm

EmergenSIG: an integrated location-based system for emergency management

Several solutions have been proposed for emergencies scenarios. These solutions include real-time data communication, location-aware, coordination, and decision-making support systems. In this context, this dissertation presents a location-awareness system fully oriented to emergency scenarios, called EmergenSIG. This approach provides and gathers important field information from an occurrence (emergency situation) and shares it to all the different agents. They include police, firefighters, medical emergency teams, among others, mobilized to the same operations theater (OT). Therefore, allowing a faster and integrated response to all the involved agents, enhancing the emergency management of the occurrence. The core of this proposal is based on a low cost solution oriented to the agents on the field (EmergenSIG mobile application), which interacts with the EmergenSIG Web application, oriented to the civil protection entities, through REST Web services. EmergenSIG focuses on medical emergencies and wildfires. It was evaluated and demonstrated in different mobile devices considering different screen sizes following a usercentered design. The system was also been evaluated and validated by real entities and civil protection agents on simulated emergency scenarios.Várias soluções têm sido propostas para cenários de emergências médicas . Estas soluções incluem comunicações de dados em tempo real ,sensíveis á localização , coordenação e sistemas de apoio à tomada de decisão. Neste contexto, esta dissertação apresenta um sistema sensível à localização totalmente orientada para cenários de emergência, chamada EmergenSIG. Esta abordagem proporciona e reúne importantes informações de uma ocorrência (situação de emergência) compartilhando-a para todos os diferentes agentes. Nos quais se incluem a polícia, bombeiros, equipas de emergência médica, entre outros, que se mobilizaram para o mesmo teatro de operações (TO). Portanto, permite uma resposta mais rápida e integrada para todos os agentes envolvidos, aumentando a eficácia da gestão da emergência de uma ocorrência. O cerne desta proposta é baseada numa solução de baixo custo direcionada para os agentes no terreno (aplicação móvel EmergenSIG), que interage com o aplicativo Web EmergenSIG, orientada para as entidades da proteção civil, através de serviços Web REST. O EmergenSIG centra-se em emergências médicas e incêndios florestais. Foi avaliada e demonstrada em diferentes dispositivos móveis, considerando diferentes tamanhos de ecrã e seguindo um design centrado no utilizador. O sistema também foi avaliado e validado por entidades reais e agentes da proteção civil em cenários de emergência simulados

Collaborative Human-Computer Interaction with Big Wall Displays - BigWallHCI 2013 3rd JRC ECML Crisis Management Technology Workshop

The 3rd JRC ECML Crisis Management Technology Workshop on Human-Computer Interaction with Big Wall Displays in Situation Rooms and Monitoring Centres was co-organised by the European Commission Joint Research Centre and the University of Applied Sciences St. Pölten, Austria. It took place in the European Crisis Management Laboratory (ECML) of the JRC in Ispra, Italy, from 18 to 19 April 2013. 40 participants from stakeholders in the EC, civil protection bodies, academia, and industry attended the workshop. The hardware of large display areas is on the one hand mature since many years and on the other hand changing rapidly and improving constantly. This high pace developments promise amazing new setups with respect to e.g., pixel density or touch interaction. On the software side there are two components with room for improvement: 1. the software provided by the display manufacturers to operate their video walls (source selection, windowing system, layout control) and 2. dedicated ICT systems developed to the very needs of crisis management practitioners and monitoring centre operators. While industry starts to focus more on the collaborative aspects of their operating software already, the customized and tailored ICT applications needed are still missing, unsatisfactory, or very expensive since they have to be developed from scratch many times. Main challenges identified to enhance big wall display systems in crisis management and situation monitoring contexts include: 1. Interaction: Overcome static layouts and/or passive information consumption. 2. Participatory Design & Development: Software needs to meet users’ needs. 3. Development and/or application of Information Visualisation & Visual Analytics principle to support the transition from data to information to knowledge. 4. Information Overload: Proper methods for attention management, automatic interpretation, incident detection, and alarm triggering are needed to deal with the ever growing amount of data to be analysed.JRC.G.2-Global security and crisis managemen

PICT-DPA: A Quality-Compliance Data Processing Architecture to Improve the Performance of Integrated Emergency Care Clinical Decision Support System

Emergency Care System (ECS) is a critical component of health care systems by providing acute resuscitation and life-saving care. As a time-sensitive care operation system, any delay and mistake in the decision-making of these EC functions can create additional risks of adverse events and clinical incidents. The Emergency Care Clinical Decision Support System (EC-CDSS) has proven to improve the quality of the aforementioned EC functions. However, the literature is scarce on how to implement and evaluate the EC-CDSS with regard to the improvement of PHOs, which is the ultimate goal of ECS. The reasons are twofold: 1) lack of clear connections between the implementation of EC-CDSS and PHOs because of unknown quality attributes; and 2) lack of clear identification of stakeholders and their decision processes. Both lead to the lack of a data processing architecture for an integrated EC-CDSS that can fulfill all quality attributes while satisfying all stakeholders’ information needs with the goal of improving PHOs. This dissertation identified quality attributes (PICT: Performance of the decision support, Interoperability, Cost, and Timeliness) and stakeholders through a systematic literature review and designed a new data processing architecture of EC-CDSS, called PICT-DPA, through design science research. The PICT-DPA was evaluated by a prototype of integrated PICT-DPA EC-CDSS, called PICTEDS, and a semi-structured user interview. The evaluation results demonstrated that the PICT-DPA is able to improve the quality attributes of EC-CDSS while satisfying stakeholders’ information needs. This dissertation made theoretical contributions to the identification of quality attributes (with related metrics) and stakeholders of EC-CDSS and the PICT Quality Attribute model that explains how EC-CDSSs may improve PHOs through the relationships between each quality attribute and PHOs. This dissertation also made practical contributions on how quality attributes with metrics and variable stakeholders could be able to guide the design, implementation, and evaluation of any EC-CDSS and how the data processing architecture is general enough to guide the design of other decision support systems with requirements of the similar quality attributes

Enhanced health event detection and influenza surveillance using a joint Veterans Affairs and Department of Defense biosurveillance application

<p>Abstract</p> <p>Background</p> <p>The establishment of robust biosurveillance capabilities is an important component of the U.S. strategy for identifying disease outbreaks, environmental exposures and bioterrorism events. Currently, U.S. Departments of Defense (DoD) and Veterans Affairs (VA) perform biosurveillance independently. This article describes a joint VA/DoD biosurveillance project at North Chicago-VA Medical Center (NC-VAMC). The Naval Health Clinics-Great Lakes facility physically merged with NC-VAMC beginning in 2006 with the full merger completed in October 2010 at which time all DoD care and medical personnel had relocated to the expanded and remodeled NC-VAMC campus and the combined facility was renamed the Lovell Federal Health Care Center (FHCC). The goal of this study was to evaluate disease surveillance using a biosurveillance application which combined data from both populations.</p> <p>Methods</p> <p>A retrospective analysis of NC-VAMC/Lovell FHCC and other Chicago-area VAMC data was performed using the ESSENCE biosurveillance system, including one infectious disease outbreak (Salmonella/Taste of Chicago-July 2007) and one weather event (Heat Wave-July 2006). Influenza-like-illness (ILI) data from these same facilities was compared with CDC/Illinois Sentinel Provider and Cook County ESSENCE data for 2007-2008.</p> <p>Results</p> <p>Following consolidation of VA and DoD facilities in North Chicago, median number of visits more than doubled, median patient age dropped and proportion of females rose significantly in comparison with the pre-merger NC-VAMC facility. A high-level gastrointestinal alert was detected in July 2007, but only low-level alerts at other Chicago-area VAMCs. Heat-injury alerts were triggered for the merged facility in June 2006, but not at the other facilities. There was also limited evidence in these events that surveillance of the combined population provided utility above and beyond the VA-only and DoD-only components. Recorded ILI activity for NC-VAMC/Lovell FHCC was more pronounced in the DoD component, likely due to pediatric data in this population. NC-VAMC/Lovell FHCC had two weeks of ILI activity exceeding both the Illinois State and East North Central Regional baselines, whereas Hines VAMC had one and Jesse Brown VAMC had zero.</p> <p>Conclusions</p> <p>Biosurveillance in a joint VA/DoD facility showed potential utility as a tool to improve surveillance and situational awareness in an area with Veteran, active duty and beneficiary populations. Based in part on the results of this pilot demonstration, both agencies have agreed to support the creation of a combined VA/DoD ESSENCE biosurveillance system which is now under development.</p
