The frequency and intensity of extreme heat events (EHE) are expected to increase with climate change. Understanding the ways in which the environment influences health outcomes during EHE is critical to mitigating their effect both now and in the future through targeted interventions and adaptations. Most previous work has been done to assess the impact of the outdoor weather conditions and social factors which increase risk during EHE; however, few studies have been able to analyze the role of indoor conditions missing a critical component of the environment where much of the U.S. population spends the majority of their time. This study will fill this information gap through a case-control study design and regression analyses. Working with the New York City (NYC) Fire Department Emergency Medical Services we compiled the Patient Care Reports and indoor temperature and humidity levels for over 5000 patients who placed emergency calls during the summer of 2016. In order to collect indoor data, paramedics carried portable sensors into buildings while responding to 911 calls which passively monitored temperature and relative humidity. To compare conditions, we also downloaded outdoor weather dataset and pollution data for this time period. First we analyzed the relationship between the outdoor and indoor environments with a generalized linear model. Additionally, we identified heat waves during this summer period with temperatures above the 95th percentile for NYC for two or more consecutive days. We then conducted a case-control study in order to understand the relationship between indoor conditions and emergency calls.
