A decentralized approach to maintenance of intravenous therapy.
A prospective experiment was conducted in a university-affiliated hospital to evaluate the effectiveness of a core of specially trained staff nurses in the maintenance of IV therapy. Five staff nurses for each of two experimental units were trained for 1 month by an IV nurse educator and were expected to perform venipuncture and monitor peripheral IV care on their units. On three control units, IV therapy continued to be a shared function of all medical house staff and nurses. During this study, 876 IV infusions on 707 patients were studied. There was a decrease in the phlebitis rate on experimental units from baseline to study periods of from 33.5% to 20.9% (relative risk, controlled for duration of the use of an IV device, 0.53, p = 0.05), whereas the rate on control units increased slightly (23.8% to 26.7%, p = greater than 0.5). Regardless of duration of use, steel needles were associated with lower phlebitis rates than were plastic catheters. The mean duration that each infusion device was in place was significantly shorter on experimental units than on control units (2.4 vs. 3.3 days, p = less than 0.001). However, bacterial colonization of IV devices occurred more often on experimental units than on control units both at baseline (12.7% vs. 7.1%; p = 0.25) and during the study phase (19.4% vs. 5.9%; p = less than 0.01). This increased colonization occurred with IV infusions started by both physicians and nurses. There were no septic complications of IV therapy in the patients studied. Patient comfort, measured by number of sticks for each venipuncture and patient interview, was significantly improved (p = less than 0.001) on experimental units during the study phase. Costs to start such a decentralized IV program on 10 clinical units was calculated to be about +10,000. This study provides information useful to those making administrative decisions regarding the value of IV teams or other methods for IV therapy maintenance. We concluded that a decentralized program can be successful with commitment of time and money resources and with a system of monitoring to ensure compliance with written IV guidelines.
