    Association between ambient temperature and increased total length of hospital stay of patients with cardiopulmonary disease in Hong Kong by Chenxiang Long, Shengyu Guo, Ping Tian, Yingying Sun

    Published 2024-12-01
    “…BackgroundWhile temperature extremes have been shown to be associated with an increased risk of hospital admissions, evidence of their impact on the length of hospital stay, which may capture the lingering effects of temperature extremes, is scarce.ObjectivesWe aimed to evaluate the association between daily variation in ambient temperature and daily variation in daily total length of stay (daily TLOS), a composite measure encompassing the daily count of hospital admissions and their corresponding length of hospital stay among cardiopulmonary patients. …”
