<h3>ABSTRACT</h3> Medicine is increasingly complex, involving a highly connected system of people, resources, processes, and institutions. Attempts to improve care involve disruptions this system, with the potential for wide-ranging consequences, both positive negative. Despite this, many improvement methodologies are poorly equipped manage either complexity or risk – instead focusing on discrete interventions whose effects narrowly monitored. Engineers have long understood that complex...

This paper investigates the connection between patient satisfaction, waiting time, staff and service time. It uses a variety of models to enable improvement against experiential operational health goals. Patient satisfaction levels are estimated using model based on (waiting times). Staff time spent with patients (service time). An integrated effective level model, is then proposed (using queuing theory). links connecting two important concepts, namely, experience efficiency in care delivery...

Abstract A wide range of disciplines are directing their methods and tools to help address the challenges healthcare. Chief among these design operational research (OR). Though they have much in common, two existed isolation for most history there is currently a gulf between communities. In this position paper, we rapidly review contributions OR We then identify similarities complementarities communities when consider healthcare systems. Finally, propose practical steps enable better...

Purpose – The purpose of this paper is to review the historical development quality assessment methods in manufacturing industry and healthcare. It examines gap between across two sectors, as well extent which industrial techniques have been successfully adopted Finally, a proposal for new approach presented.

This paper suggests a generic simulation platform that can be used for real-time discrete event modeling. The architecture of the proposed system is based on tested flexible input data developed in Labview, inter-process communication module between Labview application and software (in this case Arena). Two example applications healthcare manufacturing sectors are provided to demonstrate ease adaptability such physical system.

Abstract This contribution departs from an existing model, the Design Framework for Systems-of-Systems Resilience, to explore systems resilience issues across health, environmental, and economic domains. The reported research activities include 1) a rapid review collect set of indicators 2) design workshop employing causal loop diagramming map expected influences between indicators. Through this exercise, we examine key themes in domain outline directions further enquiry, while involving...

This paper discusses the application of Discrete Event Simulation (DES) in modelling complex relationship between patient types, case-mix and operating theatre allocation a large National Health Service (NHS) Trust London. The simulation model that was constructed described main features nine theatres, focusing on operational processes throughput times. used to test three scenarios demonstrate potential using as cost effective method for understanding issues healthcare operations management...

This paper proposes the foundation for a flexible data input management system as vital part of generic solution quick-response decision making. Lack comprehensive layer between acquisition and processing systems has been realized thought of. The proposed FDILA is applicable to wide variety volatile manufacturing environments. It provides platform that enables designers define any number entry points types regardless their make specifications in standard fashion. achieved by providing...

This paper introduces a new technology platform that improves the efficiency and effectiveness of simulation modelling projects. A recently developed integrates data acquisition management (primary models) post performance analysis models (synthesis) is described. The use real-time discrete event modelers as vehicle proposed. In recent years we have suggested number solutions to integrate shopfloor with higher level information systems. All these lacked two key capabilities. Firstly, were...

Abstract The healthcare sector is facing significant challenges that require a systems approach, resulting in rapid growth the application of approaches since beginning 21st century. Consequently, practitioners and policymakers now desire to understand evidence-base for but little evidence kind desired exists. This paper first step conducting narrative review based on systematic academic grey literature. First, emergence approach explored. Second, specific examples applications are examined...

The growing demand for better quality of care, together with an increasing awareness limited resources, is bringing attention to the need design in healthcare. In mental health, considered largest single cause disability UK, great. Existing services often fail meet current levels and do not consistently deliver good care all service users. delivery systems has potential improve user experience outcomes. This paper reports how through interactive participatory method storytelling, key...

Abstract Current healthcare delivery challenges are multi-faceted, requiring multiple perspectives to be addressed using a systems approach. However, significant amount of design research work is carried out within single disciplines or at best few working together. There appears little deliberate attempt draw together wide range committed overcome differences and tackle some the complex in delivery. In this paper, we report on initial outcomes such an international initiative that, form...

To explore the frequency and nature of complaints compliments reported to Patient Advice Liaison (PALS) in individuals undergoing surgery for a chronic subdural haematoma (cSDH).A retrospective study PALS user interactions.Individuals treatment cSDH between 2014 2019.PALS referrals from patients with 2019 were identified. Case records reviewed data on frequency, factors leading up complaint extracted coded according Healthcare Complaints Analysis Tool (HCAT).Out 531 identified, 25 (5%) had...

Abstract Healthcare systems are under strain, this creates a challenge for designers to develop solutions better health and care delivery. This paper presents sandbox of illustrative design themes used improve based on state the art research projects. These were collated from presentations at The Second International Meeting Systems Design Research, held DTU-Technical University Denmark. Attending groups mapped their keywords, target journals methodologies in order gain insight communities landscape.

Objectives Traumatic brain injury (TBI) is a global health problem, whose management in low-resource settings hampered by fragile systems and lack of access to specialist services. Improvement complex, given the interaction multiple people, processes institutions. We aimed develop mixed-method approach understand TBI pathway based on lived experience local supported quantitative methodologies determine potential improvement targets. Design describe narrative exploration, participatory...

Bad design in safety-critical environments like healthcare can lead to users being frustrated, excluded, or injured. In contrast, good make it easier use a service correctly, with impacts on both the safety and efficiency of delivery, as well experience patients staff. The participative dimension an improvement strategy has recently gained traction quality literature. However, role expertise professional been much less explored. Good does not happen by accident: takes specific reasoning that...
