Participants (≥65 years) with peripheral intravenous catheter of this study were recruited from geriatric units at a Taipei medical center hospital by purposive sampling. Based on the admitting time, 64 patients were first assigned to the povidone-iodine group from September to November in 2012 and then 85 patients were assigned to the chlorhexidine-alcohol group from November 2012 to January 2013. Total of patients were 149. A Likert 6-point (0~5) scale of Visual Infusion Phlebitis(VIP) was used to assess the patients’ phlebitis conditions, Score 1 and 2 are considered phlebitis, The higher the score the more severe the patient had phlebitis. Score 2 and above, indicated the catheter must be removed. The data were collected three times a day by ward nurses during the patients with an intravenous catheter. The data was analyzed with SPSS 20.0 for windows, crosstabs, percentage, Kaplan-Meier curve, Chi square test, Log rank test and Cox regression analysis were used. The results showed that the risk of 39.7% developing phlebitis among chlorhexidine-alcohol group was lower than 59.6% of that among the povidone-iodine group (χ2 : 4.939, p = 0.026). After controlling sex, age, Charlson comorbidity index, the site of injection, intravenous infusion, with or without using antibiotics, and diabetes with Cox regression, the risk of developing phlebitis of chlorhexidine-alcohol group was 0.569 times compare with povidone-iodine group (p = 0.044). The peripheral intravenous catheters dwell time (87.5 hours) among the povidone-iodine group was 10.1 hours shorter than those (97.6 hours) in chlorhexidine-alcohol group (p = 0.127). Overall, this study shows using 2% chlorhexidine alcohol solution for skin preparation could effectively reduce the risk of phlebitis and prolong catheter dwell time for hospitalized elderly patients with peripheral intravenous catheter.
