RESUMEN
Objective To establish an extended nursing service model for intravenous treatment in outpatient,so that patients with venous catheters nearby can receive catheter maintenance,which can reduce the medical cost and the incidence of complications during the maintenance of the catheters.Methods A three-level network of catheter maintenance was established in the area to evaluate the rate of return maintenance and the incidence of complications [catheter-related infection,medical adhesive-related skin injuries (MARSI) and catheter blockage] during catheterization.Results The rate of patient return maintenance as statistically signif-icant between the first half of 2015 and the second half of 2016 (60.0％ vs.29.7％,P=0.000).Compared with the first half of 2015,the incidence of catheter-related infections decreased in the second half of 2016 from 8.6％ to 3.3％,the incidence of MARSI decreased from 29.7％ to 10.1％,and the incidence of catheter blockage decreased from 8.5％ to 0.6％.(All P =0.000).Conclusion The comprehensive extended service mode for outpatient with venous catheters can reduce the incidence of complications during catheter maintenance,which can reduce the workload of outpatient intravenous treatment and also provide patients the convenience of catheter maintenance,and is worthy of clinical promotion.
