ANALISA HARI RAWAT INAP DAN FREKUENSI FOTO THORAK TERHADAP RATA-RATA DOSIS SERAP RADIASI PADA PASIEN COVID-19 DI RUANG ISOLASI RSU KARSA HUSADA BATU

Abstract

In the treatment process of patients with covid-19, thorax photo action is done periodically every three days. The average length of hospitalization of covid patients in the isolation room is at least nine days or up to the results of negative swab tests and standard thorax photo images. The purpose of the study was to analyze the effect of hospitalization days and the frequency of action on the amount of radiation absorption dose received by Covid-19 patients in Covid-19 isolation rooms as an evaluation material to improve aspects of occupational safety and health in the environment and society (patients). Design observational research with a cross-sectional approach. The population of all Covid-19 patients in isolation rooms at RSU Karsa Husada is 200 people. A sample of 200 respondents with probability sampling techniques. Independent variables are the length of hospitalization and frequency of thoracic photos. The dependent variable is the Decree of the Head of BAPETEN Number: 1211/K/V/2021 concerning the Indonesian Diagnostic Reference Level for CT Scan and General Radiography X-Ray Modalities (photo of PA position thorax, surface absorption dose of 0.4 mGy). The results showed the long-standing effect of hospitalization on the average dose of radiation absorption in patients (p-value 0.030), and there was an effect on the frequency of thorax photos against the average dose of radiation absorption in patients (p-value 0.000). This research can be developed using more specific variables and with a larger population and more variation. Keywords: Absorption doses, Hospitalization Days, and Thorax Photo Action
