Abstract
Purpose
This paper aims to investigate the process performances in Emergency Departments (EDs) with a novel data-driven approach, permitting to discover the entire patient-flow, deploy the performances in term of time and resources on the activities and flows and identify process deviations and critical bottlenecks. Moreover, the use of this methodology in real time might dynamically provide a picture of the current situation inside the ED in term of waiting times, crowding, resources, etc., supporting the management of patient demand and resources in real time.
Design/methodology/approach
The proposed methodology exploits the process-mining techniques. Starting from the event data inside the hospital information systems, it permits automatically to extract the patient-flows, to evaluate the process performances, to detect process exceptions and to identify the deviations between the expected and the actual results.
Findings
The application of the proposed method to a real ED revealed being valuable to discover the actual patient-flow, measure the performances of each activity with respect to the predefined targets and compare different operating situations.
Practical implications
Starting from the results provided by this system, hospital managers may explore the root causes of deviations, identify areas for improvements and hypothesize improvement actions. Finally, process-mining outputs may provide useful information for creating simulation models to test and compare alternative ED operational scenarios.
Originality/value
This study responds to the need of novel approaches for monitoring and evaluating processes performances in the EDs. The novelty of this data-driven approach is the opportunity to timely connect performances, patient-flows and activities.

Abstract
Purpose
The purpose of this study is twofold: exploring new queue-based variables enabled by process mining and evaluating their impact on the accuracy of waiting time prediction. Such queue-based predictors that capture the current state of the emergency department (ED) may lead to a significant improvement in the accuracy of the prediction models.
Design/methodology/approach
Alongside the traditional variables influencing ED waiting time, the authors developed new queue-based predictors exploiting process mining. Process mining techniques allowed the authors to discover the actual patient-flow and derive information about the crowding level of the activities. The proposed predictors were evaluated using linear and nonlinear learning techniques. The authors used real data from an ED.
Findings
As expected, the main results show that integrating the set of predictors with queue-based variables significantly improves the accuracy of waiting time prediction. Specifically, mean square error values were reduced by about 22 and 23 per cent by applying linear and nonlinear learning techniques, respectively.
Practical implications
Accurate estimates of waiting time can enable the ED systems to prevent overcrowding e.g. improving the routing of patients in EDs and managing more efficiently the resources. Providing accurate waiting time information also can lead to decreased patients’ dissatisfaction and elopement.
Originality/value
The novelty of the study relies on the attempt to derive queue-based variables reporting the crowding level of the activities within the ED through process mining techniques. Such information is often unavailable or particularly difficult to extract automatically, due to the characteristics of ED processes.

Abstract
Purpose
Information security awareness (ISA) mainly refers to those aspects that need to be addressed to effectively respond to information security challenges. This research used focus groups to empirically investigate the main ISA dimensions that emerge from the Italian public health-care sector. This study aims to identify the most critical dimension of ISA and to evaluate the diffusion and maturity of information security policies (ISPs) of health-care infrastructure and training programs.
Design/methodology/approach
This research adopted a qualitative research design and focus groups as a research methodology. Data analysis was conducted using the NVIVO 14 software package and followed the principles of thematic analysis.
Findings
The focus group results highlighted that health-care personnel find it difficult to comply with the main ISA dimensions, a situation that leads to risky behaviors. Password management, data storage and transfer and instant messaging applications emerged as the most critical of the main ISA dimensions in the context of this research. It also transpired that ISPs are not all-encompassing as they mainly focus on privacy problems but neglect security concerns. Finally, training programs are not fully implemented in the investigated context, thus undermining their positive enhancing role for ISA.
Originality/value
The public health-care sector emerged as a critical yet still under-investigated context. The need for an in-depth investigation of organizational sciences approaches to overcoming information security challenges is also recommended in several prior research studies.
