Abstract

Waktu tunggu yang lama dan ketidakkonsistenan alur kerja dalam layanan radiologi di Rumah Sakit Universitas Airlangga berdampak negatif terhadap kepuasan pasien dan kinerja operasional rumah sakit. Penelitian ini menerapkan metodologi Lean Six Sigma dengan kerangka kerja DMAIC untuk meningkatkan efisiensi layanan pada tiga fase utama: prapemeriksaan, selama pemeriksaan, dan pasca-pemeriksaan. Melalui pemetaan proses dan analisis SIPOC, ditemukan bahwa aktivitas administratif—terutama Penjadwalan (7.244 menit), Verifikasi Admin (2.371 menit), dan Pemeriksaan Kepesertaan (2.206 menit)— merupakan bottleneck utama yang menyumbang 78% dari total waktu tunda dan 65% dari total cacat. Kinerja sebelum perbaikan menunjukkan Sigma Level sebesar 2,644, DPMO sebesar 126.264,45, dan nilai Cpk sebesar -0,49, yang mencerminkan kapabilitas proses yang rendah. Setelah dilakukan integrasi digital, penguatan SOP, dan otomasi alur kerja, sebanyak 7.238 menit waktu tunda dan 169 cacat berhasil dieliminasi. Kinerja pasca-intervensi menunjukkan peningkatan signifikan, dengan Sigma Level naik menjadi 3,275 dan Cpk menjadi 0,92. Simulasi selama 84 hari menggunakan ExtendSim memvalidasi peningkatan tersebut, menunjukkan penurunan waktu perjalanan pasien sebesar ~44% (dari 1.101,76 menjadi 619,65 menit) dan penurunan DPMO sebesar ~70% (menjadi 37.933,53). Temuan ini menegaskan efektivitas metode Six Sigma dalam meningkatkan efisiensi, konsistensi, dan keandalan layanan radiologi di lingkungan rumah sakit.

Long waiting times and workflow inconsistencies in radiology services at Universitas Airlangga Hospital have negatively impacted patient satisfaction and operational performance. This study applies the Lean Six Sigma methodology using the DMAIC framework to improve service delivery across the pre-machine, during-machine, and post-machine phases. Process mapping and SIPOC analysis revealed that administrative tasks—particularly Scheduling (7,244 minutes), Admin Verification (2,371 minutes), and Eligibility Check (2,206 minutes)—were identified as key bottlenecks, contributing to 78% of total delays and 65% of total defects. Pre-intervention performance showed a Sigma Level of 2.644, DPMO of 126,264.45, and a Cpk of -0.49, indicating poor process capability. Through the implementation of digital integration, SOP reinforcement, and workflow automation that leads to eliminating several activities, 7,238 minutes of delay and 169 defects were eliminated. Post-intervention metrics demonstrated substantial improvements, with the Sigma Level rising to 3.275 and Cpk increasing to 0.92. An 84-day simulation using ExtendSim validated these improvements, confirming an approximately 44% reduction in patient journey time (from 1,101.76 to 619.65 minutes) and a 70% decrease in DPMO (to 37,933.53). These findings affirm the effectiveness of Six Sigma in enhancing the efficiency, consistency, and reliability of radiology workflows in hospital settings.
