This study was undertaken to explore associations between seasonal and environmental factors and cases of TT presenting to our children's hospital, which is located in a humid continental climate (4 distinct seasons). METHODS: A retrospective IRB-approved database was constructed to identify non-traumatic cases of acute TT (presentation <24h from onset) in non-neonatal pediatric patients (age≤21). Weather and environmental data were collected on the day of and day prior to onset. Associations were tested with Fisher's exact test. Differences in temp between seasons and months were tested with Kruskal-Wallis rank sum test. Poisson loglinear models were fit to assess relationships between seasonal and monthly counts of TT and daily average temp. RESULTS: There were 149 TTs over a 10 year period (2013-2023). Median age was 14 (IQR 12-16). There was a larger than expected percentage of TTs in December (13%, CI 9-20%, p<0.05). The December median of average daily temps was 36F (IQR 29-44), which was the second coldest month after January (median 35F, IQR 31-38), and preceded by significantly warmer November (median 43F, IQR 38-48; Kruskal-Wallis p<0.001). The median winter average temp was 36F (IQR 30-41) which was the lowest, preceded by fall (median 54F, IQR 46-66; p<0.001). There was a marginally larger than expected percentage of TTs in winter (31%, CI 24-39%, p=0.11). Poisson loglinear models suggest an association between lower temps and seasonal/monthly TT (p<0.05 and p=0.05). A decrease of 10F predicts∼5 additional TTs in the seasonal model and ∼1-2 additional TTs in the monthly model. CONCLUSIONS: In our humid continental climate, TT appears to occur at lower temps with more cases during colder months. Further study into seasonal and environmental factors associated with TT is warranted in other climates. Our institutional call schedule is being modified to account for the increased caseload of these emergent surgeries during colder months.
