Patient-journey modelling and simulation in computed tomography

Abstract

Purpose – The purpose of this paper is to present a business process reengineering (BPR) framework of process and data integration with patient journey as the basis for process evaluation and the improvement of patient-flow. Design/methodology/approach – A BPR framework is developed using a mixed-method research design, which incorporated a case study to demonstrate a healthcare scenario with associated processes and data elements, using process models based on event-driven process chain methodology as well as patient and data models, based on unitary structuring technique. The framework includes key processes including patient booking and rebooking, and associated inputs, outputs, and control parameters. In this case, the framework is demonstrated through application to computed tomography (CT) services in a hospital to improve patient-flow, with numerical simulation of CT data collected over time. Findings – The framework supports flexible patient scheduling and the associated planning of healthcare operations and logistics – this in turn helps to improve patient-flow. Furthermore, mathematical modelling and simulation precisely reveal the impact of booking and rebooking on the performance of the CT department. Research limitations/implications – This innovative framework has potential value for other services, within and beyond the hospital setting. Originality/value – The proposed framework of process modelling, data, and patient journey addresses the lack of a holistic approach to monitoring and evaluating service performance in hospital settings. Patient journey modelling is an integral part of process and data models that can be implemented in an integrated system environment such as an enterprise resource planning system for real-time monitoring of patient-flow under dynamic conditions.

Structured literature review on business process performance analysis and evaluation

“…A lot of research aimed at revealing ways to improve the process from the point of view of performance and outcomes. Studies on business process performance analysis are focused on improvement of process design (Corradini et al, 2015), complex processes in software industry (Abu Rub, Issa, 2012), processes in hospital setting (Samaranayake et al, 2015).…”

Identifying logistical parameters in hospitals: Does literature reflect integration in hospitals? A scoping study

“…20 Aronsson et al state that in order for an organization to be effective, a supply chain strategy is required for the system as a whole. 6 In a more integrated perspective, attention is claimed for all hospital processes and resources, 21 instead of focusing on an individual department, such as the operating room (OR) or the intensive care unit. On a regional level, Poulin claims that horizontal interorganizational arrangements in relation to SCM are largely understudied.…”
