Abstract

There has been an increase of the COVID-19 case in December, 2023. For this reason, learning from previous data is needed to anticipate so that the spike in COVID-19 cases does not happen again. This study aims to identify risk factors that influence the survival of COVID-19 patients using the Cox proportional hazard model from medical record of COVID-19 patients at RSU Bahteramas for the period March to December 2020. The results of the study show that the Cox proportional hazards model in COVID-19 patients is h ( t ) = h 0 ( t ) exp ( 1 , 5274 X 2 - 1 , 4639 X 4 ) . The risk factors that influence the survival of COVID-19 patients are age (X2) and administration of drugs and vitamins (X4) from the fourth independent variables involved. The hazard ratio value for the age variable is 4.6063 > 1, which indicates that the risk of COVID-19 patients aged > 60 years experiencing death is 4.6063 times faster than COVID-19 patients aged ≤ 60 years, while the hazard ratio value for drug administration and vitamins is 0.2313 < 1, which indicates that COVID-19 patients who take drugs and vitamins during the treatment period will be reduced by 0.2313 times compared to patients who only take drugs without vitamins.
