Association between extreme heat and hospital admissions for cataract patients in Hefei, China

Abstract

Cataract is the first cause of blindness and the major cause of visual impairment worldwide. Under conditions of global warming, researchers have begun to give attention to the influence of increasing temperature on cataract patients. Our paper aimed to investigate the association between extreme heat and hospital admissions for cataract in Hefei, China. Based on data from the New Rural Cooperative Medical System and National Meteorological Information Center, we used a generalized additive model and a distributed lag nonlinear model to examine the relationship between extreme heat and hospitalizations for cataract, with consideration of cumulative and lagged effects. When current mean temperature was above 28 °C, each 1 °C rise was associated with a 4% decrease in the number of cataract admissions (RR = 0.96, 95% CI = 0.94–0.98). The cumulative relative risk over 11 days of lag was the lowest, which indicated that every 1 °C increase in mean temperature above 28 °C was associated with a 19% decrease in the number of hospital admissions for cataract (RR = 0.81, 95% CI = 0.75–0.88). In subgroup analyses, the negative association between extreme heat and hospital admissions for cataract was stronger among patients who were not admitted to provincial-level hospitals. In conclusion, this paper found that extreme heat was negatively associated with cataract hospitalizations in Hefei, providing useful information for hospitals and policymakers.

Seasonal Variation and Source Identification of PM10 in an Industrialized City

“…Identification of pollution sources is a crucial stage in air quality management since it allows for better understanding of pollution control techniques and estimation of their respective contributions. [ 21–27 ] Modeling strategies involving source‐oriented or receptor models to associate emissions from pollution sources are referred to as source apportionment of particles. [ 28–34 ] Using robust mathematical tools, such data give essential knowledge for identifying and quantifying PM sources.…”

“…Since 1906, the average global temperature has risen by 0.74 °C, and this trend is expected to accelerate over the next century. As global warming continues, worldwide extreme heat occurrences are growing, which is intimately related to the health and activities of humans (Xie et al, 2020). Exposure to heat, which will rise as a result of global warming, has been associated with an increased risk of a variety of cause-specific hospitalizations (Xu et al, 2020).…”

The impact of physical environment on health-care workers’ well-being in Chinese hospitals during COVID-19 pandemic

“…Organizational commitment as an effective factor of emotional attachment or loyalty to the organization is a professional ability (Karami et al , 2017). Xie et al (2020) found that in case of shortage of HWs for epidemic treatment, HWs from other departments will come to support. However, even with this emergency back-up, some hospitals face other challenges in early identification and management crises such as lack of intensive care resources.…”
