Introduction: an active system of surveillance of nosocomial infections (NI) saves money for hospitals, healthcare systems, and above all, impacts the lives of patients.
Objective: Describe the behavior of nosocomial infections (NI) at the Speciality Hospital and its impact on patients and the hospital.
Methodology: transversal descriptive study was conducted from January to June 2011. Variables were prevalence, overstay and mortality attributable to NI. All hospitalized patients in the infections surveillance system were included. Data analysis used included frequency, Student’s t, Mann Whitney U test with confidence interval of 95%.
Results: of the 8,388 patients discharged from hospital, 565 patients were identified with a total of 815 NI. The average age of all patients was 49.13 ± 17.9, age of patients with IN was 49.28 ± 18.3 years with a median of 50 years (p = 0.42). Pneumonia was the most common NI at 24.2%, followed by bacteremia, 20.9%, urinary tract infections, 15.2%, catheter-related infections, 13%, surgical site infections, 11.4%. Overall mortality was 5.93%, and mortality of patients with NI was 25.15%. The probability of death was 76.6% for patients with NI (p <0.00). The services with the most hospital overstays from NI were hematology with 1552 day.
Conclusions: NI are costly to hospitals and healthcare systems, many of these deaths are preventable with a system of epidemiological surveillance to establish efficient Ni prevention and control measures, and continuous clinical practice monitoring.
