Phlebitis Grading Scale

Phlebitis should be documented using a uniform standard scale for measuring grade and severity. Any incidence of phlebitis greater than grade 2 should be reported to the physician and other appropriate healthcare personnel. Ongoing observation of sites should continue for 48 post removal to detect post-infusion phlebitis. All patients with an intravenous access device should have the IV site checked every shift for signs of infusion phlebitis. The subsequent score and action(s) taken (if any) must be documented.
