Construction of Preoperative Assessment Program for Day Surgery in Geriatric Cataract Patients: An Evidence-Based Delphi Study.

Abstract

Purpose: To construct a scientific cataract day surgery preoperative assessment program to provide a scientific assessment tool for health care providers.

Design: Literature review, two-round e-Delphi study, and quantitative studies.

Methods: With the recommended opinions of clinical practice guidelines for cataract surgery as the guiding framework, an item pool was formed on the basis of literature review and guideline content analysis, and the dimensions and items of evaluation program were determined by two rounds of correspondence consultation using Delphi expert method. Then, 315 patients from an ophthalmic hospital were selected for investigation to analyze its reliability and validity.

Findings: The positive coefficients for the 2 rounds of correspondence with experts were 100.00% and 95.83%, and the authority coefficients were 0.90 and 0.89. Kendall's coordination coefficient W values of 0.29 and 0.24 for the first and second rounds and the differences were statistically different (P < .05). The coefficient of variation was 0.14 and 0.10, respectively. The formal assessment items included 3 first-level indicators, 12 secondary-level indicators, and 48 tertiary indicators, with an overall Cronbach's coefficient of 0.66 and cumulative variance contributions of 69.19%, 65.84%, and 57.15% for the 3 first-level indicators.

Conclusion: The high reliability of the preoperative cataract day surgery program compiled by applying evidence-based analysis and the Delphi method can provide scientific guidance to clinical nurses for preoperative assessment, which in turn ensures patient safety and improves the quality of patient access services.
