Lamanya waktu tunggu pelayanan pasien pulang rawat inap di RSUD KiSA Kota Depok mengakibatkan lamanya perpindahan pasien dari IGD yang diindikasi perlu rawat inap, serta lamanya proses pulang dapat meningkatkan infeksi nosokomial. Hal ini merupakan alasan pentingnya pemantauan proses pemulangan pasien yang selama ini belum pernah dilakukan, dan perlunya ditentukan target waktu tunggu proses pemulangan pasien rawat inap. Tujuan penelitian adalah mengetahui implementasi Lean Six Sigma pada proses pasien pulang rawat inap dalam upaya perbaikan mutu pelayanan rawat inap di RSUD KiSA, dengan tahapan Define, Measure, Analyze, Improve dan Control berfokus pada penurunan aktivitas non value added serta pemborosan dengan meningkatkan aktivitas value added. Penelitian ini menggunakan pendekatan kualitatif dengan desain action research, menggunakan metode wawancara mendalam, observasi dan telaah dokumen, serta implementasi perbaikan proses pemulangan pasien rawat inap. Hasil penelitian menunjukkan setelah dilakukan pendekatan Lean Six Sigma dapat diidentifikasi pemborosan tertinggi adalah waste waiting dan selanjutnya dilakukan upaya perbaikan waktu tunggu pelayanan pasien pulang rawat inap berfokus pada pengurangan kegiatan pemborosan. Kondisi awal proses pemulangan pasien diketahui ratio VA hanya 23,9% dan ratio NVA sebesar 76,1% dengan Lead Time 315,08 menit. Sehingga terjadi penurunan Lead Time menjadi 192,50 menit dengan peningkatan rasio VA menjadi 30,6%. Rekomendasi dari penelitian ini adalah perlunya penetapan alur proses pemulangan pasien serta dilakukan pemantauan waktu tunggu melalui indikator mutu unit rawat inap. Proses evaluasi dilakukan untuk menilai mutu layanan yang diberikan sudah memberikan manfaat bagi pasien dan operasional pelayanan rumah sakit.

The long waiting time for inpatient discharge services at the KiSA Hospital in Depok City results in a long transfer of patients from the emergency room who are indicated to need hospitalization, and the length of the discharge process can increase nosocomial infections. This is the reason for the importance of monitoring the patient discharge process which has never been done before, and the need to set a target waiting time for the inpatient discharge process. The research objective was to determine the implementation of Lean Six Sigma in the process of inpatient discharge in an effort to improve the quality of inpatient services at KiSA Hospital, with the Define, Measure, Analyze, Improve and Control stages focusing on reducing non-value added activities and waste by increasing value added activities. This study used a qualitative approach with an action research design, using in-depth interviews, observation and document review, as well as implementation of improvements to the process of inpatient discharge. The results showed that after the Lean Six Sigma approach was carried out, it was identified that the highest waste was waste waiting and further efforts were made to improve the waiting time for inpatient services focusing on reducing wasteful activities. The initial condition of the patient's discharge process is that the VA ratio is only 23.9% and the NVA ratio is 76.1% with a lead time of 315.08 minutes. So that there is a decrease in Lead Time to 192.50 minutes with an increase in the VA ratio to 30.6%. The recommendation from this study is the need to determine the flow of the patient discharge process and monitor waiting time through inpatient unit quality indicators. The evaluation process is carried out to assess the quality of services provided that have benefited patients and hospital service operations.
