Inter-Dialytic Weight Gain (IDWG) atau peningkatan berat badan diantara dua tindakan hemodialisis (HD) menjadi salah satu indikator keberhasilan terapi pasien HD. Semakin tinggi IDWG, maka semakin banyak cairan yang menumpuk di dalam tubuh pasien dan semakin berat dampak yang ditimbulkan. Semakin lama seseorang menjalani HD, semestinya semakin banyak yang diketahuinya tentang penyakitnya dan cara mencegah komplikasi sehingga IDWG semestinya semakin turun. Penelitian ini bertujuan untuk mengetahui hubungan antara lama waktu menjalani hemodialisis dengan IDWG. Penelitian korelasional ini dilakukan secara cross sectional dengan melibatkan 34 pasien yang telah menjalani hemodialisis minimal 1 tahun di RSUD Dumai, dapat berkomunikasi secara verbal, dan dapat berdiri untuk menimbang berat badan. Data lama waktu menjalani hemodialisis dilihat dari catatan medis pasien. Adapun IDWG dihitung dalam periode siklus satu minggu menjalani hemodialisis menggunakan timbangan dan dicatat di lembar observasi. Data dianalisis menggunakan uji Spearman. Hasil penelitian menunjukkan median 22 serta nilai minimum dan maksimum yaitu 12 dan 86 bulan. Untuk data IDWG median adalah 3 serta nilai minimum dan maksimum yaitu 1 dan 4,5 kilogram. Analisis hubungan menunjukkan tidak ada hubungan antara lama waktu menjalani hemodialiasis dengan IDWG pada pasien hemodialisis di RSUD Dumai (p value = 0,952) dengan nilai r = 0,01. Diharapkan perawat menganalisis pengetahuan serta pemahaman pasien tentang perlunya mengontrol asupan cairan dan berat badan terutama pada pasien yang telah lama menjalani hemodialisis untuk mencegah kenaikan IDWG yang dapat memperberat kondisi pasien.Kata kunci: Cairan, IDWG, lama hemodialisis AbstractInter-Dialytic Weight Gain (IDWG) becomes an indicator of successful of hemodialysis patients treatment. More IDWG indicates more fluid accumulates in the patient’s body and more impact caused by the excess fluid. This study aimed to investigate relationship between length of undergoing hemodialysis and Inter-Dialytic Weight Gain (IDWG) in Hemodialysis Patients. The study was correlational study with cross sectional approach. Samples of the study were 34 patients. Samples were recruited from hemodialysis patients who have been undergoing hemodialysis at least 1 year in Dumai General Hospital, were able to communicate verbally and to stand up for measuring body weight, and willing to participate in the study. Length of undergoing hemodialysis was taken from medical records. IDWG was measured in one week period of cycle of undergoing hemodialysis using a scale and observation sheet. The result showed the average length of time undergoing hemodialysis was 26.65 months, SD was 15.55, median was 22 and minimum and maximum values were 12 and 86 months respectively. The mean of IDWG was 2.73 kilograms with SD was 1.046, median 3 and minimum and maximum values were 1 and 4.5 kilograms respectively. Result of the study showed that there was no relationship between length of time undergoing hemodialysis and IDWG (p value = 0.952) with r = 0.01. Nurses are expected to further analyze patients’ knowledge as well as understanding about the need to control intake of fluid and body weight to prevent problems caused by kidney damage which suffered by hemodialysis patients.Keywords: Fluid excess, hemodialysis patients, IDWG
