Application and Delphi Validation of an Omaha System–Based Evaluation Index for Post-PCI Rehabilitation Nursing

Background: This study aimed to develop an evaluation index system based on the Omaha System to identify postoperative rehabilitation nursing problems in patients after percutaneous coronary intervention (PCI). This evaluation system aims to facilitate the timely identification of nursing problems and enhance the reliability of nursing interventions during postoperative rehabilitation. Methods: Rehabilitation nursing problems were identified through a comprehensive literature review and case analysis, considering both the physical and psychological characteristics of post-PCI patients. These problems were classified and organized according to the Omaha System. From September 2020 to February 2021, Delphi consultations were conducted with experts in China to finalize the evaluation indicators. Results: After two rounds of expert consultation, the authority coefficients of the experts were 0.858 and 0.875, and Kendall’s W coefficients were 0.194 and 0.150, respectively (both P < 0.01), indicating consensus. The final evaluation index system comprised 4 first-level indicators (domains), 21 second-level indicators (nursing problems), and 130 third-level indicators (specific symptoms/signs). Conclusion: The Omaha System-based evaluation index developed in this study offers a clinically applicable framework for identifying and managing rehabilitation nursing problems in PCI patients. Supporting comprehensive and systematic assessment provides nurses with clear guidance for problem recognition, individualized care planning, and outcome monitoring. Its application has the potential to enhance care consistency, improve patient recovery, and promote evidence-based nursing decision-making, thereby contributing to improved quality of post-PCI rehabilitation care in clinical practice.
