Abstract: Objective: To investigate the QCC (QCC) in elderly patients with peripheral venous indwelling needle puncture success rate effect. Method: the establishment of QCC team, selected for the elderly patients with peripheral venous indwelling needle puncture success rate as the theme, analyses the reasons of success rate of elderly patients with peripheral vein indwelling needle, formulate corresponding measures and implementation, and evaluate the effect of. Results: to carry out QCC in elderly patients after peripheral intravenous indwelling needle in use rate and success rate of indwelling than QCC before the increase of needle puncture (P0.01 and P0.05).Conclusion:QCC can effectively improve the elderly patients with peripheral venous indwelling needle puncture success rate of utilization and.
