 Developing a patient flow visualization and prediction model using aggregated data for a healthcare network cluster in Southwest EthiopiaBalew Ayalew Kassie and Geletaw Sahle Tegenaw PLOS Digital Health, 2023, vol. 2, issue 11, 1-15 Abstract: A health information system has been created to gather, aggregate, analyze, interpret, and utilize data collected from diverse sources. In Ethiopia, the most popular digital tools are the Electronic Community Health Information System and the District Health Information System. However, these systems lack capabilities like real-time interactive visualization and a data-driven engine for evidence-based insights. As a result, it was challenging to observe and continuously monitor the flow of patients. To address the gap, this study used aggregated data to visualize and predict patient flow in a South Western Ethiopia healthcare network cluster. The South-Western Ethiopian healthcare network cluster was where the patient flow datasets were collected. The collected dataset encompasses a span of 41 months, from 2019 to 2022, and has been obtained from 21 hospitals and health centers. Python Sankey diagrams were used to develop and build patient flow visualizations. Then, using the random forest and K-Nearest Neighbors (KNN) algorithms, we achieved an accuracy of 0.85 and 0.83 for the outpatient flow modeling and prediction, respectively. The imbalance in the data was further addressed using the NearMiss Algorithm, Synthetic Minority Oversampling Technique (SMOTE), and SMOTE-Tomek methods. In conclusion, we developed a patient flow visualization and prediction model as a first step toward an end-to-end effective real-time patient flow data-driven and analytical dashboard in Ethiopia, as well as a plugin for the already-existing digital health information system. Moreover, the need for and amount of data created by these digital tools will grow along with their use, demanding effective data-driven visualization and prediction to support evidence-based decision-making.Author summary: Predicting patient flow is essential for improving efficiency, resource allocation, and process optimization. However, the majority of existing literature targets exploring the length of stay, waiting time, treatment time, test turnaround time, and boarding time within a single healthcare institution and between different departments within the institution (i.e., intra-patient flow analysis). Whereas little is explored about the flow of patients with the network structure or organization. Our study tried to investigate the flow of patients in the Healthcare Network Cluster in Southwest Ethiopia, where healthcare is structured in a 3-tier fashion and the referral patient flow starts from the lower primary healthcare level to the secondary level on the way to the tertiary level or a specialized hospital. The inter-patient flow analysis can help identify areas for improvement in the coordination of care and the efficient use of resources by tracking the flow of patients from one primary healthcare provider to specialized care and analyzing the characteristics of that flow. Furthermore, our study only takes into account direct flow patients who use or follow the traditional healthcare system structure, not indirect flows or alternative forms of healthcare access.
