Proses pengembalian rekam medis pasien rawat jalan di RSUP Fatmawati masih belum optimal, ditunjukan dengan penyelenggaraan yang belum sesuai dengan peraturan, masih ada rekam medis yang terlambat, bahkan tidak kembali dari Instalasi Rawat Jalan (IRJ) ke Instalasi Rekam Medis dan Pusat Data Informasi (IRMPDI) pada hari dimana rekam medis digunakan. Penelitian ini dilakukan untuk mendapatkan hasil analisis proses pengembalian rekam medis pasien rawat jalan dari IRJ ke IRMPDI dengan pendekatan lean six sigma. Jenis penelitian ini adalah operational research, dengan desain penelitian kuantitatif dan kualitatif. Hasil penelitian digambarkan dengan value stream mapping yang memperlihatkan lead time proses pengembalian rekam medis pasien rawat jalan selama 183,09 menit dengan value added 41,55 menit (22,7%) dan non value added 141,54 menit (77,3%), proses paling lama terjadi pada langkah pengembalian rekam medis dari IRJ ke IRMPDI karena menunggu petugas IRMPDI mengambil rekam medis. Waste paling besar yaitu waste waiting sebesar 124,16 menit atau 87,72% dari total seluruh waste yang ditemukan. Berdasarkan analisis fishbone diagram diketahui bahwa akar penyebab masalah paling banyak berasal dari kategori man. Berdasarkan analisis tersebut diberikan usulan berupa pembuatan standarisasi kerja, penghitungan beban kerja, melakukan rapat koordinasi, membagi pekerjaan ke dalam periode waktu tertentu (heijunka), dan meningkatkan pengawasan.

The process of returning outpatient medical records at RSUP Fatmawati is not optimal enough, indicated by the process is not in accordance with existing regulations, medical records are late, and not returned from Outpatient Installation (IRJ) to Installation of Medical Record and Information Data Center (IRMPDI) at the same day when it used. The aim of this research is to get analysis result of outpatient medical records return process from IRJ to IRMPDI using lean six sigma approach. This research is operational research type that use quantity and quality design. The results of this research were described with the value stream mapping that showed lead time of outpatient medical records return process for 183,09 minutes, with value added 41,55 minutes (22,7%) and non value added 141,54 minutes (77,3%), the longest process occurs on returning of medical record form IRJ to IRMPDI due to the waiting of IRMPDI officers to take medical records. The biggest waste is waiting for amount of 124,16 minutes (87,72%) of the total waste. Based on fishbone diagram analysis it is known that the root cause of medical record problem mostly comes from man category. Based on that analysis, an improvement proposal will be given as the following development of work standarization, workload calculation, coordination meeting, devide the work into a certain period of time (implementation of heijunka), and improvement of supervision.
