Variation in indications for cataract surgery in the United States, Denmark, Canada, and Spain : results from the international cataract surgery outcomes study.
Backgroundlaims-International comparisons of clinical practice may help in assessing the magnitude and possible causes of variation in cross national healthcare utilisation.
With this aim, the indications for cataract surgery in the United States, Denmark, the province of Manitoba (Canada), and the city of Barcelona (Spain) were compared.
Methods-In a prospective multicentre study, patients scheduled for first eye cataract surgery and aged 50 years or older were enrolled consecutively.
From the United States 766 patients were enrolled ; from Denmark 291 ; from Manitoba 152 ; and from Barcelona 200.
Indication for surgery was measured as preoperative visual status of patients enlisted for cataract surgery.
Main variables were preoperative visual acuity in operative eye, the VF-14 score (an index of functional impairment in patients with cataract) and ocular comorbidity.
Mean visual acuity were 0.23 (USA), 0.17 (Denmark), 0.15 (Manitoba), and 0.07 (Barcelona) (p<0.001), When restricting the sample to eyes with normal retina and macula, no significant difference between United States and Denmark was observed (p>0.05).
Mean VF-14 scores were 76 (USA), 76 (Denmark), 71 (Manitoba), and 64 (Barcelona) (p<0.001).
Conclusion-Similar indications for cataract surgery were found in the United States and Denmark.
Significantly more restricted indications were observed in Manitoba and Barcelona. (...)
