Objective To construct the sensitive index of nursing quality suitable for peripheral venous indwelling needle.

Methods Taking "structure-process-outcome" as the research framework and combining with literature retrieval, specialist group discussion and Delphi technique letter consultation, the sensitive index system of peripheral venous indwelling needle nursing quality was formed.

Results Two rounds of expert letter consultation were conducted in this study. The positive coefficients of experts were 100.00% and 94.12%, respectively, and the authority coefficients of experts were 0.908 and 0.912, respectively. Kendall concordance coefficient of the first round of expert letter consultation for the first, second and third indexes were 0.214, 0.284 and 0.296, respectively, and Kendall concordance coefficient of the second round were 0.238, 0.324 and 0.259, respectively. The index system consists of 3 first-level indexes, 9 second-level indexes and 23 third-level indexes.

Conclusion The constructed quality sensitive index system of peripheral venous indwelling needle has a reasonable structure, high scientificity and practice, and provides a basis for nursing quality evaluation and quality improvement of clinical venous indwelling needle.
