QUALITY OF AIR BACTERIA IN OPERATING THEATER IN SOME HOSPITALS IN JAKARTA AND SURROUNDINGS AREAS IN 2018-2019

Abstract

Nosocomial infection is an infection obtained by a patient or hospital staff while in hospital. This infection plays a role in causing morbidity and mortality in hospitals and can occur in various hospitals rooms, including operating theaters. Nosocomial infections can occur due to various factors, one of which is contamination from airborne bacteria. In some countries, regulations are set to limit the concentration of airborne bacteria, both in the operating theaters and other rooms in hospitals, hence the need for monitoring and supervision of air quality as areflection on the cleanliness conditions in hospitals. Based on this, it is necessary to know the bacteriological air quality in the operating theaters in several hospitals in Jakarta and surrounding areas as one of the steps to prevent nosocomial infections. The method uses an air sampler with the principle of impaction. Air sampler works by separating the particles from the air by utilizing the inertia of the particles to force the bacteria to settle to the surface of the medium. A total of 217 examinations in the operating theaters were carried out in 17 hospitals in Jakarta and surrounding areas during January 2018 to June 2019. The majority of the operating theaters in hospitals in Jakarta and surrounding areas have air quality that met appropriate quality standards. In 2018, 120 of 137 (87.59%) examination in the operating theaters met the quality standar. Meanwhile in 2019, 70 of 80 (87.50%) operating theaters met the standard determined by the Ministry of Health of the Republic of Indonesia. Key words: air sampler method, operating theater, quality of air bacteria
