INS and Hypoglycemia: In the optimized group, the time to achieve blood glucose standard (6.59 ± 1.94) d and insulin pumping time (7.14 ± 1.89) d were shorter than those in the general group [(7.48 ± 2.12) d and (8.58 ± 2.14) d], insulin dosage (748.85 ± 63.61) U was less than that in the general group (923.54 ± 84.14) U, and the incidence of hypoglycemia (3.70%) was lower than that in the general group (16.67%), and the satisfaction rate (92.59%) was higher than that of the general group (77.78%), which was statistically significant (P < 0.05).
