It has been suggested that the risk of hospital infection differs according to the moment of hospital stay. Through a retrospective cohort of 843 surgery patients the effect of several factors on nosocomial infection risk is studied as a function of the duration of the hospital stay. It was observed that the studied variables (operation, type of surgery, age and severity of underlying disease) had a predisposing effect on the appearance of infection in short stays (less than 14 days), being the effect greater in longer stays. It is concluded that hospital stay can act as a modifier of the effect of several factors on the risk of hospital infection.
有人认为，医院感染风险会因住院时间的不同而有所差异。通过对843名手术患者进行回顾性队列研究，分析了几个因素对医院感染风险的影响，并将其作为住院时间的函数。研究发现，所研究的变量（手术、手术类型、年龄和基础疾病的严重程度）在短期住院（少于14天）时对感染的出现有诱发作用，且在住院时间较长时这种作用更大。研究得出结论，住院时间可以作为几个因素对医院感染风险影响的调节因素。
