Ventilator-associated pneumonia is the most common health-care-associated infection in the intensive care unit (ICU) and computer-assisted diagnosis and surveillance is called for. The frequency of ventilator-associated pneumonia was assessed prospectively during a 6-month period in the ICUs of a teaching hospital in Tehran, Islamic Republic of Iran. To determine the accuracy of the Iranian Nosocomial Infections Surveillance (INIS) system, patient data were input to the software and compared with physicians' judgement. The frequency of ventilator-associated pneumonia was 21.6%, or 9.96 episodes per 1000 ventilator days. The duration of admission to the ICU, duration of mechanical ventilator and number of re-intubations were significantly higher in patients who developed pneumonia. The INIS system identified 100% of cases, with no false-positive or false-negative results. Compared with developed countries, the frequency of ventilator-associated pneumonia was high in our ICUs, and INIS software was accurate in diagnosing nosocomial infection.
呼吸机相关性肺炎是重症监护病房（ICU）中最常见的医院获得性感染，需要进行计算机辅助诊断和监测。在伊朗德黑兰一所教学医院的 ICU 中，我们进行了为期 6 个月的前瞻性研究，以评估呼吸机相关性肺炎的发生频率。为了确定伊朗医院感染监测（INIS）系统的准确性，我们将患者数据输入到软件中，并与医生的判断进行比较。呼吸机相关性肺炎的发生率为 21.6%，即每 1000 个呼吸机日发生 9.96 例。发生肺炎的患者入住 ICU 的时间、使用机械呼吸机的时间和再次插管的次数明显较高。INIS 系统识别出了 100%的病例，没有假阳性或假阴性结果。与发达国家相比，我们的 ICU 中呼吸机相关性肺炎的发生率较高，INIS 软件在诊断医院感染方面非常准确。
