8% of rated dialysis centers in Oklahoma have 4 or 5 stars, against 23% nationally. The average rating is 2.3 stars (U.S. 2.8).
Look at the star rating and at the outcome verdicts, then at practical things: distance (most patients go three times a week), whether the center has an evening shift if you work, and whether it offers training for home dialysis if you might want it later. Visit, and ask how many patients each nurse looks after.
