Abstract Details

Purpose:

The purpose of this study was to analyze how patient-reported outcome measures can be connected to clinical outcome measures in cataract surgery in order to identify opportunities for improvement of quality of care.

Setting:

Forty-two Swedish cataract surgery clinics

Methods:

Two models were used to analyze the following questions: 1. Is there a relationship between clinical parameters and a poor patient-reported outcome? 2. What characterizes patients with a good clinical outcome but a poor patient-reported outcome? The study material consisted of follow-up data on cataract extractions collected by the Swedish National Cataract Register in 2008-2011. Patient-reported outcome was measured using the Catquest-9SF questionnaire. A total of 14,928 pairs of questionnaires completed before and after a cataract extraction were analyzed together with clinical data. The number of participating clinics was 42. The analyses were performed for each clinic.

Results:

For almost all clinics a factor related to a poor patient-reported outcome after surgery was a good preoperative self-assessed visual function. For some clinics this was very obvious with up to 50% of the patients stating that they were very satisfied with their vision before surgery. For single clinics different factors like large anisometropia (?3D), capsule complications, ocular co-morbidity and long waiting time were related to a poor patient-reported outcome. In situations where the clinical outcome was good and the patient-reported outcome poor problems with near vision activities after surgery was the main factor noted. The clinics showed a large variation of which clinical parameters that were related to a poor patient-reported outcome.

Conclusions:

Analyzing the risk factors for a poor patient-reported outcome for each clinic showed a large variation. Weak indication for surgery, refractive problems after surgery, surgical complications and a poor chance of visual recovery due to ocular co-morbidity were among the reasons for a poor patient-reported outcome. Post-operative care in terms of establishing a good near vision seemed to be another problem for some clinics.
