Introduction: infections have been associated with health care services, the onset of an infection in the hospital adds an unexpected condition to the patient, increasing the hospital stay, which may result in irreversible sequelae, or lead to death.
Objective: to characterize the risk factors and clinical parameters of healthcare-associated infections at León Cuervo Rubio Provincial General-Teaching Hospital. Pinar del Río, 2014.
Method: a descriptive and cross-sectional study was conducted in a target group of 330 patients with healthcare-associated infections in the chosen institution and the sample was comprised of 321 patients who were selected by a simple random sampling. The information was collected from the medical records and the statistics registry of patients with such infections. The clinical-epidemiological variables studied were: age, gender, risk factors, location of infection, healthcare service of origin, and isolated microorganism.
Results: a marked prevalence in patients older than 68 years and male (59.50%) was observed. Extreme age was the most present risk factor (33%), followed by ventilation (28%). The most frequent location of infection was the respiratory tract (60%), the highest risk was recorded in the Intensive Care Unit (37.69%), and the most isolated microorganism was Escherichia coli.
Conclusions: the incidence of healthcare-associated infection is greater in male patients older than 68 years, being the extreme age and mechanical ventilation the most frequent risk factors, as well as respiratory tract infections, with a higher incidence in the Intensive Care Unit. In most of these healthcare-associated infections Escherichia coli was the isolated germ.
