Impact of clinical and patient-reported outcomes on patient satisfaction with cataract extraction
Abstract
Background
To date, factors that influence satisfaction with cataract surgery have not been broadly explored.
Objective
To identify variables related to patient satisfaction after cataract extraction by phacoemulsification and to determine the relationship between satisfaction and visual acuity (VA) and visual function (VF).
Design
Prospective cohort study.
Setting
Five hospitals belonging to the Basque Health Care Service.
Participants
4335 consecutive patients undergoing cataract extraction.
Interventions
Clinical data on vision were collected before the intervention and 6 weeks afterwards. Before cataract extraction, patients answered a global question about their expectations for the procedure, answered three questions related to specific activities (reading, going out and recognizing people, and doing housework) and completed the Visual Function-14 (VF-14) and Short-Form-36 (SF-36) instruments. Three months after cataract extraction, they again completed the VF-14 and SF-36 along with questions about global satisfaction with the procedure and satisfaction with the three specific activities.
Main outcome measures
Three months after cataract extraction, they again completed the VF-14 and SF-36 along with questions about global satisfaction with the procedure and satisfaction with the three specific activities.
Results
Pre-intervention VA and VF-14 scores and their post-intervention changes were associated with both global satisfaction and satisfaction with the ability to perform specific activities. Unresolved ocular complications were related to global satisfaction with cataract extraction (OR 95% = 0.39(0.27, 0.55), P < 0.001). Both the mental and physical component scales of the SF-36 were related to global satisfaction. A group of patients were not satisfied with the intervention in spite of achieving similar vision-related improvements as patients who were quite satisfied with the procedure.
Conclusion
Satisfaction with cataract extraction is related to clinical outcomes and is also associated with patients' expectations of their improvement in visual function.
