Overview

Randomized trial analyzes weather and air quality effects on ophthalmic attendance, suggesting implications for planning.

Key Points

  • This research aims to quantify the short-term effects of weather and air quality on ophthalmic outpatient attendance in eastern China.
  • Analyzed 3,788 days of attendance data from a tertiary ophthalmology department in Jiangsu, China.
  • Utilized a time-stratified case-crossover design with conditional Poisson regression to assess impacts.
  • Evaluated exposure effects from meteorology, nitrogen dioxide, and particulate matter over variable timeframes.
  • Each additional extreme-heat day corresponded to a 3.9% reduction in attendance (rate ratio 0.961, 95% CI 0.954–0.967, p < 0.0001).
  • Each additional heavy-rainfall day was associated with a 6.3% reduction in attendance (rate ratio 0.937, 95% CI 0.923–0.952, p < 0.0001).
  • Lag analyses suggested delayed positive rainfall associations without a similar pattern for heat over a 21-day period.
