Exploratory Data Analysis for Preventive and Corrective Maintenance for Medical Equipment in a General Hospital from the Health Institute of the State of Mexico

Abstract

AbstractThe “Nicolas San Juan” General Hospital, is a second level public hospital located at Toluca City, belonging to the Health Institute of the State of Mexico. It has a technological capacity of 534 medical devices, most of which (69%) are older than eleven years. In 2021, the total maintenance interventions performed by the Biomedical Engineering Service technical staff was 724. It was observed that more than 50% interventions were corrective maintenance (CM). The high demand for this maintenance could be related to the age of the devices.The objective of this work was to carry out an Exploratory Data Analysis (EDA) using the R Studio suite, to find out if there is any relation between different variables relate to medical devices, and to discover patterns or anomalies that provide auxiliary criteria for decision-making in preventive and corrective maintenance management. The EDA was realized based on data from 349 work orders for medical devices located in six critical areas of the Hospital: surgical suite, intensive care and intermediate therapy units, emergency room, neonatology, and the central sterilization unit. Among the main results, it was detected a strong relationship between the total of corrective maintenance and the age of medical devices.KeywordsCorrective maintenancePreventive maintenanceExploratory data analysisHealthcare technology management
