Who is Most at Risk? Heat-Related Morbidity and Mortality among Individuals with Pre-Existing Chronic Diseases: Space-Time Stratified Analyses

We select patients with general and heat-related illness, specifically
individuals with pre-existing COPD, diabetes, hypertension, heart
failure, neurodegenerative, CKD and chronic mental health problems.
Individuals with CKD is selected based on estimated glomerular
filtration rate (eGFR<45), which corresponds to moderate to severe
CKD, including stages 3b, 4, and 5.17 Chronic mental health problems is defined by identifying patients diagnosed with specific ICPC-2 codes and prescribed medication treatment. We uses an aggregated daily number of counts spanning 2005-2019.
