Objective To explore the establishment of the health management platform through network hospital, and to investigate the effect of the implementation of the continuity health management after discharge on the type 2 diabetes mellitus patients with the use of insulin .Methods Forty-eight type 2 diabetes mellitus patients with the use of insulin received the continuity health management , and individualized education of the use of insulin during the hospital and the continuity health follow-up management through network hospital after discharge.The scores of the compliance , knowledge and injection practice of the use of insulin , the comprehensive ability of management diabetes , and the levels of fasting blood glucose (FBG) and HbA1c were compared in patients 3 months after the intervention .Results The scores of the compliance , knowledge and injection practice of the use of insulin , the comprehensive ability of management diabetes were respectively (7.35 ±0.95), (82.52 ±8.54), (117.47 ±12.42) after the intervention, and were higher than (6.49 ± 1.52), (56.54 ±10.93), (80.86 ±15.71) before the intervention, and the differences were statistically significant (t=4.955 9, 14.003 8, 13.639 6, respectively;P<0.01).The levels of FBG and HbA1c were respectively (6.20 ±0.85) mmol/L, (6.56 ±0.91) % after the intervention, and were lower than (8.53 ± 2.16)mmol/L, (8.73 ±1.72)% before the intervention, and the differences were statistically significant (t=5.985 7,9.003 9, respectively;P <0.01 ) .Conclusions The implementation of the continuity follow-up management through network hospital after discharge in type 2 diabetes mellitus patients with the use of insulin can significantly improve the compliance , knowledge and injection practice of the use of insulin in patients , and establish patients ’ self-management action well so as to help them control glucose .
