THURSDAY, Aug. 1 (HealthDay News) -- Factors associated with patient-reported outcomes after cataract excision have been identified and may be useful for improving quality of care, according to a study published in the August issue of Optometry and Vision Science.
To identify opportunities for improvement of quality of care, Mats Lundström, M.D., Ph.D., from Lund University, and Ulf Stenevi, M.D., Ph.D., from Sahlgren's University Hospital in Mölndal -- both in Sweden, analyzed three models of how patient-reported outcomes can be connected to clinical outcome measures in cataract surgery. Follow-up data on cataract extractions collected by the Swedish National Cataract Register from 2008 to 2011 were assessed. The Catquest-9SF questionnaire was used to measure patient-reported outcome, and 9,707 pairs of questionnaires were completed before and after cataract extraction.
The researchers found that preoperative self-assessed visual function, preoperative visual acuity in both eyes, postoperative visual acuity, and ocular comorbidities were the factors related to any change in patient-reported outcomes after surgery. Good preoperative self-assessed visual functions, poor preoperative visual acuity in the better eye, ocular comorbidity, surgical complications, and large refractive deviation were the factors related to poor patient-reported outcomes after surgery. The main factor identified in situations where clinical outcome was good and patient-reported outcome was poor was poor near vision after surgery.
"The best models to give ideas for improved quality of care by using a patient questionnaire in our study were analyzing the risk factors for a poor patient-reported outcome and analyzing the factors associated with disagreement between clinical outcomes and patient-reported outcomes," the authors write.
