Taxonomy for patient safety incidents in cataract surgery
Keywords:
cataract extraction, patient safety, medical errors, classificationAbstract
Introduction: Cataract surgery is considered a safe and effective procedure, but it is not without risks. Scientific evidence reveals that errors in the process of this intervention can harm patients. Variability has been observed in the approaches used for the definition, categorization and reporting of patient safety incidents in cataract surgery.
Objective: To develop a taxonomy for patient safety incidents in cataract surgery.
Methods: A mixed sequential study was carried out at the Holguin Ophthalmologic Center between January 2023 and June 2024. In the first phase, the taxonomy was developed from qualitative techniques such as content analysis and focus group. It was then implemented as a basis for incident detection. Finally, it was evaluated by expert judgment in two rounds.
Results: A specific taxonomy for patient safety incidents related to cataract surgery was obtained, structured in three levels of hierarchy and composed of 10 categories and 37 subcategories. After a second round of expert evaluation, a high content validity (0.689 according to Fleiss' Kappa test) and very good reliability (0.959 according to the Kuder-Richardson test) were achieved for a confidence level of 95%.
Conclusions: A taxonomy was developed that provided a specific conceptual and classificatory framework, for patient safety incidents in the cataract surgery.
