Evaluating the Short-term Environmental and Clinical Effects of a Radiation Oncology Department's Response to the COVID-19 Pandemic.

Purpose: During the COVID-19 pandemic, many radiation oncology departments worldwide adopted the use of shorter and more intense hypofractionated regimens. Hospital foot traffic was reduced through virtual care. This study's primary objective was to assess the collective environmental effect of these strategic changes by identifying sources of carbon dioxide equivalents (COe).

Supporting hospital renewal through strategic environmental sustainability programs.

Although the impact the environment can have on human health is well understood, the healthcare system's impact on the environment is a topic that's only been explored since the mid-1990s. More recent has been a realization of the risks that climate change poses to health and healthcare. Although there are numerous direct benefits for hospitals adapting environmental sustainability programs, this article examines how the systemic approach taken by the University Health Network's (UHN) Energy & Environment program not only improves the hospital's environmental performance and provides significant cost savings but also supports several areas of focus that are part of UHN's current journey of renewal.

The impact of telemedicine on greenhouse gas emissions at an academic health science center in Canada.

Objective: This study estimates the reduction in greenhouse gas (GHG) emissions resulting from 840 telemedicine consultations completed in a 6-month time period. Our model considers GHG emissions for both vehicle and videoconferencing unit energy use. Cost avoidance factors are also discussed.
