Abstract
Open Source Electronic Medical Records (EMR) and Electronic Health Records (EHR) are widely used in healthcare institutions because it is mostly free and customizable. Generally, EMRs and EHRs are used in healthcare institutions because their adoption reduces costs and improves patient outcomes through increased efficiency. During the adoption of EMRs/EHRs, whether open-source or closed-source, the number one concern of healthcare institutions is their workflow. When adopting any open-source software, there is a lot to consider, “ Free does not mean you have to compromise on utility .” Process mining helps to discover and analyze the actual process executions of an information system (IS). In this paper, we use process mining to check the conformance of the workflow of Open-Source EMRs (workflow from event logs of an EMR) and the workflow of hospitals (workflow of hospitals based on domain knowledge). We modeled the workflow of hospital processes using business process modeling notation (BPMN) and converted it into a Petri net. Event log extracted from an Open-Source EMR (OpenEMR) was preprocessed for process conformance checking in ProM Framework. We check the conformance of log and model using alignment and replay. We display the results based on four metrics (fitness, precision, simplicity, and generalization). Then, we filter logs to check the conformance of Role-based access controls. Our conformance checking results showed that processes in Open-Source EMR align with the processes executed by hospitals.
Highlights
Information systems (IS) used by organizations fall into two categories; they are either purchased or free (Open-source software (OSS))
PRELIMINARIES We introduce and define the basic terms and concepts used in this paper, i.e., open-source software (OSS), Electronic Medical Records (EMR), HER, business process modeling notation (BPMN), Process Model, Event Logs, and access controls
To check conformance of ROLE-BASED ACCESS CONTROL (RBAC) defined in Open-Source EMR (OpenEMR) with RBAC specified in domain knowledge, we filtered the log as:
Summary
Information systems (IS) used by organizations fall into two categories; they are either purchased ( known as Closed-source, Commercial or Proprietary Software) or free (Open-source software (OSS)). With the considerable cost involved in the purchase, implementation, and support of proprietary software, many organizations opt for OSS than proprietary software. The healthcare industry’s adoption and use of EMRs/EHRs are the. Many open source EMRs/EHRs are available and used by many today [2]. Free acquisition of OSS EMRs/EHRs does not entirely make their use easy. Research literature document that users have many challenges with using EMRs/EHRs (whether open or closed source). It is necessary to ensure an OSS acquired meets the organization’s requirements, such that the processes to be executed in the OSS align with the real processes of the organizations; i.e., there are no deviations between the two.
