Abstract

Abstrak. Tuberculosis (TBC) merupakan suatu penyakit saluran pernafasan yang
disebabkan bakteri Mycobacterium Tuberculosis dan dapat menyebabkan kematian.
Meskipun demikian, dengan perawatan yang tepat, penyakit ini dapat disembuhkan.
Penelitian ini bertujuan untuk menentukan faktor-faktor yang mempengaruhi laju kesembuhan
pasien penderita TBC di Rumah Sakit dr. M. Djamil Padang serta memodelkan
laju kesembuhan pasien dan mengetahui laju kesembuhannya. Data lama rawat
inap pasien penderita TBC di Rumah Sakit dr. M. djamil Padang berdistribusi Weibull
sehingga metode analisis yang digunakan adalah analisis survival dengan model regresi
Cox-Weibull. Diketahui bahwa faktor-faktor yang mempengaruhi laju kesembuhan
pasien TBC penderita TBC adalah usia dan jenis kelamin. Dari nilai odds ratio diketahui
bahwa pasien dengan jenis kelamin perempuan memiliki resiko sembuh sebesar
0,721 kali lebih besar dibandingkan pasien dengan jenis kelamin laki-laki dan diketahui
juga bahwa jika usia bertambah satu tahun maka resiko penderita TBC untuk mencapai
kesembuhan bertambah sebesar 1,007 kali dibandingkan pasien lain. Dari penelitian
ini diketahui juga bahwa kebiasaan merokok berkolerasi dengan variabel jenis kelamin.
Sehingga meskipun pengaruh kebiasaan merokok terhadap laju kesembuhan pasien penderita
TBC tidak nyata,namun pengaruh ini dapat dianggap diwakili oleh variabel jenis
kelamin.
