Construction of comprehensive evaluation indexes for percutaneous coronary intervention in acute coronary syndrome

Objective To construct the evaluation index and comprehensive effect index of percutaneous coronary intervention (PCI) for the acute coronary syndrome (ACS).

Methods The Delphi method combined with the comprehensive index method was used to determine the indicators and weights for evaluating the effect of PCI for ACS.

Results After 2 rounds of Delphi expert consultation, the expert positive coefficients were 100% and 95.24%, the authority coefficients were 0.847 and 0.871, and the Kendall coordination coefficients were 0.364 and 0.403 (P < 0.05). Through the comprehensive index method, the evaluation indicators and weights were obtained: 2 first-level indicators including emergency mode (0.473) and cardiac catheterization room mode (0.527); 19 second-level indicators; and 41 third-level indicators.

Conclusions The constructed evaluation index and comprehensive effect index of PCI for ACS have guiding significance for the theory and practice of the technology and can provide a certain reference basis for the diagnosis and prognosis of ACS patients during the perioperative period at the level of effect evaluation.
