Impact of a National system for waitlist prioritization: the experience with NIKE and cataract surgery in Sweden.

Purpose: To evaluate waiting times for first-eye cataract surgery in Sweden following widespread adoption of the Nationell Indikationsmodell for Kataraktextraktion (NIKE) tool for prioritizing patients for cataract surgery. Methods: Waiting times for all first-eye cataract surgeries in Sweden in 2009-2011 were identified from the Swedish National Cataract Register. Waiting times were compared according to demographic, clinical and NIKE indication group for surgery. Multivariate logistic regression modelling was used to determine factors associated with waiting times less than the 3-month Government guarantee period. Results: There were 141 070 first-eye cataract surgeries in 2009 to 2011; an annual increase of around 6%. Over the study period, mean waiting times decreased across all NIKE groups. The proportion waiting
