AM, Al-Hazmi, H., Al-Zahrani, T., & Elmalky . 2014
Background:
Hospital acquired infections (HAI) have emerged as an important public health problem and are a leading cause of morbidity and mortality worldwide. They affect both developed and resource-poor countries and constitute a significant burden both for the patient and for the health care system. Specific objectives in this study are assessment of HAI rate among patients admitted with other principle diagnosis, to identifying the causative agents of hospital acquired infections and to identify some possible risk factors associated with each type of infection, both health related and non-health related.
Patients and Methods:
The study was done on selected diagnosis groups during year 2010. The infections were found among 250 patients (43.6% males) have been exposed to episodes of infections. Median age of patients was 56. Data were abstracted from the archived patients’ files in medical record department using the annually infection control log-book prepared by the infection control department. The Data collected were demographic information about the patients (age and sex), clinical condition (diagnosis and the length of hospital stay) and possible risk factors for infection as smoking, diabetes mellitus, hypertension and exposure to invasive devices or exposure to surgical procedures.
Results:
Liver diseases 22.8%, cardiac diseases 22.8%, Gastro-Intestinal System diseases 20%, urinary system diseases 13.6%, and endocrinal disorder 13.6% Prostate gland diseases 7.2%. Episodes of infections caused by 9 types of organisms divided into 47.2% for blood stream infection and 52.8% for other types. 66% acquired blood stream infection were exposed to central venous line.
Conclusion:
Most common type of HAIs was blood stream infections. Liver, cardiac diseases and gastro-intestinal diseased patients show more proportion of HAIs while urinary system and prostate disease patients show less proportion of HAIs. Gram negative bacilli were the most common organisms found in our study (60%).
