HUBUNGAN ANTARA JUMLAH KOLONI BAKTERI PADA GAGANG DAN HANDLE PINTU TROLI GIZI DENGAN JUMLAH RUANGAN PADA ROTASI SIANG TROLI GIZI DI SEBUAH RUMAH SAKIT KOTA MALANG

Abstract

Introduction: The incidence of nosocomial infections in Indonesia is above developed countries, reaching 15,74%. Nosocomial causative bacteria can transmit during the process of distributing food from a nutritional installation to a hospitalization room. Research on the role of meal trolleys in the spread of nosocomial bacterial infections is still rare. Therefore, the purpose of this study was to determine the relationship between the number of bacteria on the handgrip and the door handle of the meal trolley with the number of rooms visited by the trolley during the afternoon rotation.

Methods: This research uses in vitro laboratory research design with post-test only observational analytic. Samples were taken in one of Malang's hospitals in August 2018. The number of samples taken was 90 with 3 repetitions. The sample is inoculated on the nutrient agar medium, MacConkey agar, and blood agar then incubated for 72 hours.

Result: There are no significant differences between the types of bacteria in the nutrient medium, MacConkey agar and blood agar. The number of bacteria on the trolley door handle is more than in the trolley handgrip but the difference is not significant. Non-lactose fermenting and non-beta hemolytic bacteria are found more in meal trolley door handles. There is no correlation between the number of bacteria colonies and the number of rooms in the handle of a meal trolley.

Conclusion: The number of meal trolley bacterial colonies is not related to the number of rooms visited by the meal trolley.
