Penelitian ini bertujuan untuk menganalisis gambaran dan efisiensipenggunaan labu darah dalam tindakan operasi di RSUP Fatmawati. Jenispenelitian ini adalah kuantitatif dengan cara mengumpulkan data pasien diinstalasi bedah sentral dan unit transfusi darah rumah sakit (709 pasien) dankualitatif dengan melakukan wawancara mendalam terhadap dokter bedah dandokter obstetric gynecology, penelitian ini menggunakan pendekatan retrospektif.Menilai nilai efisiensi penggunaan labu darah dengan melihat nilai CrossmatchedTransfusion Rate (CTR), Transfusion Probability (TP), Transfusion Index (TI),dan Nonusage Probability (NUP). Penelitian ini menunjukan bahwa nilai CTRsebanyak 2,6, TP sebanyak 44%, TI 0,95, dan NUP 0,59. Faktor-faktor penyebabpemborosan dalam penelitian ini dikarenakan antisipasi dokter dalam pemesanandarah, jenis operasi, kadar haemoglobin, faktor pengalaman dan perkiraan dokterdalam menentukan kebutuhan kantong darah.

This study aims to analyze the use of blood vials for transfusion in theoperation at Fatmawati Hospital. This research applied quantitative with reportfrom the operating theater and hospital blood transfusion unit as the source of data(709 patiens) and qualitative methode by interview surgeon and obstetrician andgynecologist, this research using a retrospective approach. Assess the efficiencyof the use of blood bags by looking at the values of Crossmatched TransfusionRate (CTR), Transfusion Probability (TP), Transfusion Index (TI), and NonusageProbability (NUP). This study shows CTR value as much as 2.6, TP as much as44%, TI 0.95, and NUP 0.59. Factors causing blood waste are higher anticipationof doctors in ordering blood, the type of surgery, haemoglobin rate, experienceand the speed of doctors in determining the needs of blood bags.
