Abstract


Berdasarkan hasil dan pembahasan, didapatkan faktor yang paling berpengaruh ter-
hadap ketahanan hidup pasien Covid-19 adalah faktor usia. Semakin besar usia pasien
maka semakin besar peluang pasien mengalami kematian akibat Covid-19 dengan risiko
pasien mengalami kematian meningkat sebesar 2,4253% setiap bertambahnya 1 tahun
usia. Rentang usia 56 – 61 tahun memiliki kondisi yang lebih rentan mengalami kematian
akibat Covid-19. Rata-rata waktu pasien Covid-19 bertahan hidup RSUP Dr. Kariadi Se-
marang secara keseluruhan adalah 10,47 hari. Berdasarkan regresi Cox stratified dengan
estimasi exact, fungsi kegagalan yang terbentuk adalah h1(t) = h1(t)exp(0, 023963X1)
untuk strata dirawat di ICU dan h2(t) = h2(t)exp(0, 023963X1) untuk strata tidak di-
rawat di ICU dengan X1 menunjukan usia. Pasien yang dirawat di ICU mempunyai
peluang risiko kematian yang lebih besar dibandingkan dengan pasien yang dirawat di
Non ICU.
