We investigated the prevalence and microbial agents and outcome in patients who was admitted to the medical intensive care unit of Rohani Hospital.  Materials & Methods : This prospective descriptive study is performed in one year from October 2009 to October 2010 in MICU patients that their tracheal intubation time was more than 48 hours . Patients that died in less than 24 hours were excluded . Diagnosis of VAP was based on CPIS . The type of microbes found in the laboratory according to standard biochemical methods . Age and Sex, cause of admission , GCS, duration of mechanical ventilation, length of stay ,APACHE score and their outcome related to patients with VAP and without VAP were recorded. The results were statistically analyzed with SPSS software, and P less than 0.05 was considered significant .  Results: Totally, 134 patients were enrolled . VAP developed in 37 patients (27.6 %), in which 18 patients died ( 48.6%). In 100 cases without VAP, 42 cases died (43.2 %). A verage length of stay in VAP and Non- VAP was 34.86 days and , 9.48 days respectively.   The incidence of VAP was 21 cases per 1,000 days of mechanical ventilation.  Conclusion: Our study has shown that the incidence of VAP in the MICU is somewhat high, and it requires immediate attention due to prolonged hospitalization and increased mortality .  Key words: Ventilator Associated-Pneumonia, Length of Stay, Mortality & Morbidity     Address: Babol University of Medical Sciences, Ayatollah Rouhani Hospital, Department of Infectious   Tel: (+98) 111 2238296, 9113112559   Email : Pamrimaleh@yahoo.com   [1] Assistant professor of Anesthesia Department, Babol University of Medical Sciences  [2] Assistant professor of Infectious Disease Department, Member of Infectious Diseases & Tropical Medicine Research Center, Babol University of Medical Sciences (Corresponding Author)   [3] Assistant professor of Surgery Department, Babol University of Medical Sciences  [4] Assistant professor of Internal Medicine Department, Babol University of Medical Sciences  [5] Medical Student, Babol University of Medical Sciences  [6] MSC in statistics, Babol University of Medical Sciences  [7] Nurse, Babol University of Medical Sciences  [8] Nurse, Babol University of Medical Sciences
