Background: The phlebitis incidence was found as the fourth highest infection in hospitalized patients. Indonesia has contributed in phlebitis incidence as the fifth highest in the world wide after India, Iran, Malaysia, and Philippines. Purpose: This study was aimed to analyze the influence of patients’ characteristic with intravena catheter to phlebitis incidence. Methods: The study design was case control study with 45 respondents in case group (diagnosed with phlebitis) and control (undiagnosed with phlebitis) group in public hospital Haji Surabaya from January to April 2017. The independent variables in this study were age, sex, nutrioninal status, hypertension history, and diabetes mellitus history. Meanwhile, the dependent variable was phlebitis incidence. Data were analyzed with multiple logistic regression. Results: Phlebitis was influenced by patients’ characteristics namely age (p = 0,01; OR = 9,63; 95% CI =3,67 < OR < 25,25), sex (p = 0,01; OR = 4,84; 95% CI =1,85 < OR < 12,66), nutritional status (p = 0,01; OR = 4,01; 95% CI = 1,69 < OR < 9,66), hypertension history (p = 0,01; OR = 6,18; 95% CI = 2,47 < OR < 15,51), and diabetes mellitus history (p = 0.01; OR = 17.88; 95% CI = 6,05 < OR < 52,85). Conclusion: Patients’ characteristics had influence on phlebitis incidence such as age, sex, nutritional status, hypertension history, and diabetes mellitus history.

ABSTRAK Terapi intravena merupakan salah satu prosedur invasif yang bertujuan untuk mensuplai cairan, obat, vitamin, komponen darah, dan monitoring status hemodinamik. Pasien yang mendapatkan terapi intravena dalam jangka panjang berisiko tinggi terinfeksi, plebitis dan ekstravasasi vena. Penelitian ini bertujuan untuk menganalisis pengaruh karakteristik pasien terpasang kateter intravena terhadap kejadian plebitis. Desain penelitan ini adalah case control dengan besar sampel 45 pasien pada kelompok kasus dan kontrol. Sampel kasus pada penelitian ini adalah pasien yang terdiagnosa plebitis sedangkan sampel kontrol adalah pasien yang tidak terdiagnosa plebitis di RSU Haji Surabaya pada bulan Januari sampai dengan April 2017. Variabel independen adalah umur, jenis kelamin, status gizi, hipertensi dan DM, sedangkan variabel dependen adalah kejadian plebitis. Pengelolahan data menggunakan analisis regresi logistik berganda. Hasil penelitian ini menunjukan bahwa dari 5 faktor terkait dengan karakteristik pasien hanya 3 faktor yang berpengaruh terhadap kejadian plebitis adalah  jenis kelamin dengan p value = 0,043 dan odds ratio = 3,45, umur dengan p value = 0,016 dan odds ratio 4,10 dan  DM dengan p value = 0,000 dan odds ratio = 9,78. Sedangkan 2 faktor yang tidak berpengaruh terhadap kejadian plebitis adalah status gizi dengan p value = 0,74 dan odds ratio = 0,79 dan hipertensi dengan p value = 0,178 dan odds ratio = 2,35. Berdasarkan hasil analisis data, dapat disimpulkan bahwa faktor dominan dan berpengaruh terhadap kejadian plebitis adalah status DM. Hasil penelitian ini diharapkan dapat menjadi acuan bagi RSU Haji Surabaya, terutama dalam prosedur pemasangan dan perawatan terapi intravena yang perlu mempertimbangkan kondisi pasienKata Kunci : Karakteristik, intravaskular, pengaruh, plebitis, terapi intravena.ABSTRACTIntravenous therapy is one of the most common invasive procedures used for injecting  fluids, drugs, blood products, nutritional and monitoring of hemodynamic status. The insertion and daily use of these devices isassociated with risk plebitis and complications that can have impact on the clinical status and outcome of the patient.. The aims of this research was  to analyze the effect of patient characteristics on intravenous catheter to the occurrence of plebitis. This study used case control with sample size 45  for each group. Case sample was patients who diagnosed with plebitis while control samples was diagnosed patients with no plebitis at RSU Haji Surabaya in January until April 2017. Independent variables were age, sex, nutritional status, hypertension and DM, whereas the depenendent variable was plebitis occurrence. Those variables was analyze with  logistic regression. The results of this study showed that the 5 factors related to the characteristics of patients only 3 factors that affect the incidence of plebitis include the gender with p value = 0.043 and odds ratio = 3.45, age with p value = 0.016 and odds ratio 4.10 and DM with p value = 0.000 and odds ratio = 9.78. While the 2 factors that have no effect on the occurrence of plebitis is the nutritional status with p value = 0.74 and odds ratio = 0.79 and hypertension with p value = 0.178 and odds ratio = 2.35. Based on the results of data analysis, it can be concluded that the most dominant factor and the effect on the occurrence of plebitis is DM status. The results of this study are expected to be a reference for RSU Haji Surabaya, especially in the installation procedure and treatment of intravenous therapy that needs to consider the condition of the patientKeywords: Characteristics, influences, intravascular, intravenous therapy, plebitis.
