Hospitals have demonstrated their enormous capacity to adapt to the rapidly changing situation imposed by the pandemic: increasing the number of intensive care units and intermediate and inpatient beds, with the corresponding human resources, services and facilities required. Internationally, the enormous demand to manage the COVID-19 pandemic has challenged hospitals in terms of staffing, supplies and equipment. This article analyses the effect of the COVID-19 pandemic on hospital activities, from the perspective of its environmental impact. It compares a year of normal hospital activities, 2019, with data on hospital activities from 2020. The aim of this research is to analyse the changes produced by the pandemic in the regular activities of the hospital and to determine the environmental impact, which allows reflecting on the exceptional situation generated. The results show that the hospital’s environmental impact increased significantly in 2020 compared to 2019, with a 17.2% increase in overall environmental efficiency indices. The main contributors to this increase were waste generation and medical gas consumption, which are critical aspects of hospital activities during the pandemic.

In the past decades, the use of indices and indicators to report on the environmental performance of organisations has increased exponentially. However, the available studies did not address the topic of obtaining indicators that show the environmental behaviour of the health sector. The main objective of this research, therefore, was aimed at the calculation of environmental efficiency indices in the hospital sector, taking a regional hospital as a case study and considering the environmental aspects identified during the development of its healthcare activity in 2019. The results obtained provided information on the potential environmental impacts triggered by every aspect of the operation of a hospital in the course of its activities that focus on patient care. The results demonstrated that the aspects related to transportation of patients, workers, and materials had the greatest impact on the global environmental indices we calculated. For the environmental efficiency indices of hospital activities, the most significant environmental aspects were materials consumption and waste generation.

New healthcare management strategies aim to reduce in-person visits and patient hospitalization while ensuring patient safety. These strategies optimize resources, alleviate pressure on healthcare services, and decrease travel and mobility within healthcare environments. This research analyzes the environmental impact and sustainability associated with transportation and mobility in traditional hospital-based healthcare services, which have been relocated to bring healthcare closer to patients. This retrospective study utilizes data from two hospital centers spanning the years 2021 to 2023. The objective is to highlight the environmental benefits and sustainability of providing healthcare in the patient’s environment. The methodology employs life cycle analysis to compare three scenarios: traditional healthcare in hospitals, healthcare provided at the patient’s location through home hospitalization and medical consultations at nearby health centers, and healthcare professionals’ travel using electric vehicles. The results demonstrate that healthcare professionals traveling to the patient’s home or nearby health centers reduce environmental impact across all analyzed impact categories. Promoting home hospitalization, specialized consultations at local health centers, and primary care can effectively reduce unnecessary patient travel and minimize environmental impact, enhancing sustainability. Health policies should prioritize actions to reduce hospital visits, emphasizing prevention over disease treatment. Such practices would not only benefit patients but further promote sustainability and environmental protection.
