Methods Height, weight, blood glucose level, diagnosis and treatment information were collected from different databases of patients with hypertension and diabetes in Baoshan District from 2017 to 2019, and the consistency of the data from different sources was analyzed. Results Both the percentages of weight and height inconsistency among patients with hypertension and diabetes together were lower in 2019 than in 2017 (10.99% vs 18.72%, χ2=822.38, P < 0.001 and 0.86% vs 2.74%, χ2=347.03, P < 0.001, respectively).In 2019, the percentage of registered hypertensive patients with abnormal traceability from diagnosis was higher than that in 2017 (12.67% vs 11.72%, χ2=4.01, P=0.045).Similar results were also obtained in patients with diabetes.Analysis of glycated hemoglobin value last position in diabetic patients showed that the coefficient of variation of the last position composition ratio of the value in 2019 was significantly lower than that in 2017 (0.19 vs 0.31).The ratio in patients with the last position of glycosylated hemoglobin value of 0 was lower in 2019(4 701 cases, 12.72%) than that in 2017 (9 485 cases, 17.14%), and the difference was statistically significant.
