Morbiditas pasien penyakit ginjal kronis memengaruhi jenis dan jumlah terapi obat yang potensial dapat menimbulkan beragam masalah terkait obat. Salah satu peran Apoteker adalah mengidentifikasi dan mencegah terjadinya masalah terkait obat. Penelitian ini bertujuan untuk mengetahui hubungan antara polifarmasi dan masalah terkait obat serta mengevaluasi jenis dan jumlah masalah terkait obat pada pasien ginjal kronis di ruang rawat inap RS PMI Bogor. Penelitian ini menggunakan rancangan studi potong lintang. Data primer adalah data masalah terkait obat. Data sekunder dari formulir pemantauan terapi obat oleh farmasi klinik. Penelitian dilakukan di ruang instalasi farmasi RS PMI Bogor periode 28 September?05 Desember 2015. Analisis univariat dilakukan untuk memperoleh gambaran distribusi frekuensi serta proporsi dari variabel yang diteliti. Analisis multivariat uji regresi logistik menguji hubungan variabel bebas, perancu, dan masalah terkait obat. Evaluasi dilakukan terhadap 682 terapi obat dari 92 orang pasien penyakit ginjal kronik. Persentase pasien dengan polifarmasi sebesar 83,7% dan pasien dengan masalah terkait obat sebesar 73,9%. Jumlah obat penyebab masalah terkait obat sebanyak 73 obat (55,3%). Jumlah masalah terkait obat dalam kategori masalah obat sebesar 207 masalah dengan persentase efek pengobatan yang tidak optimal sebesar 67,6%. Ada hubungan bermakna antara pasien yang mendapat obat polifarmasi dan kejadian masalah terkait obat (p=0,000). Pasien penyakit ginjal kronis dengan polifarmasi berisiko 21,67 kali mengalami kejadian masalah terkait obat.
