RESUMO
OBJECTIVE: To assess the impact on the incidence of PPIVC by implementing a catheter management protocol and to determine risk factors for PPIVC development in hospitalized patients. METHOD: A total of 3978 episodes of venous catheterization were prospectively included from September 2002 to December 2007. A catheter management protocol was implemented during this period of time. The incidence and variables associated to the occurrence of PPIVC were determined. RESULTS: The incidence of PPIVC from 2002 to 2007 was 4.8%, 4.3%, 3.6%, 2.5%, 1.3% and 1.8% (p<0.001). Perfusion of amiodarone [adjusted OR (AOR) 25.97; 95% CI=7.29-92.55, p=0.0001] and cefotaxime (AOR 2.90; 95% CI=1.29-6.52, p=0.01) and the shift when the catheters were placed (AOR for morning vs. night shift 0.60; 95% CI=0.35-1.02, p=0.063) were independently associated to the development of PPIVC. A history of phlebitis was the only factor independently associated to phlebitis due to peripherally inserted central venous catheters (AOR 3.24; CI at 95% CI= 1.05-9.98, p=0.04). CONCLUSIONS: A catheter management protocol decreases the incidence of PPIVC in hospitalized patients. The risk of PPIVC increases for peripherally inserted central venous catheters when the patients have a history of phlebitis and for peripheral venous catheters when amiodarone or cefotaxime are infused. Catheterization of peripheral veins performed during morning shifts is associated with a lower incidence of PPIVC when compared with night shift catheterizations.
