|October 2019||What to Expect When It Gets Hotter: The Impacts of Prenatal Exposure to Extreme Heat on Maternal and Infant Health|
with Jiyoon Kim, Maya Rossin-Slater: w26384
We use temperature variation within narrowly-defined geographic and demographic cells to show that prenatal exposure to extreme heat increases the risk of maternal hospitalization during pregnancy, and that this effect is larger for black than for white mothers. At childbirth, heat-exposed mothers are more likely to have hypertension and have longer hospital stays. For infants, fetal exposure to extreme heat leads to a higher likelihood of dehydration at birth and hospital readmission in the first year of life. Our results provide new estimates of the health costs of climate change and identify environmental drivers of the black-white maternal health gap.

with Ginger Zhe Jin, Susan Feng Lu: w25017
Medicare does not pay for a skilled nursing facility (SNF) unless a fee-for-service patient has stayed in the hospital for at least three days. Discharges after the three-day cutoff consistently result in more transfers to SNFs. Using the three-day rule as an instrument, we find that SNF discharges decrease hospital readmission for patients with comorbidities. However, for knee and hip replacement patients, we find significant increases in readmission. This perverse effect is more severe when local SNFs have lower quality. Back-of-the-envelope calculations suggest that the three-day rule may have generated extra Medicare payments to SNFs by $100-447 million per year.
