While the results were not statistically representative, the range of values is powerfully illustrative of considerable variation in performance. In one facility, prior to the intervention, only 7% of diabetic patients had undergone an eye examination in the preceding year, at the end of the pilot, in another facility, the figure was 92%. Similarly, in one location only 8% of diabetic patients had undergone a urine albumin test in the 12 months preceding the intervention, while the rate was above 80% in another at the end of 2016 (CSIH, 2015).
