[Cost-effectiveness analysis on continuous subcutaneous insulin infusion and multi-point daily insulin injections in the treatment program of type 2 diabetes].

Objective: To observe the cost-effectiveness of using continuous subcutaneous insulin infusion (CS II) and multi-point daily insulin injections (MDI) in controlling blood sugar in the newly hospitalized type 2 diabetes patients.

Methods: Retrospective analysis on 86 cases taking CS II and 103 cases using MDI on a 'blood sugar control program' among the newly hospitalized patients with type 2 diabetes. The period for observation was 2 weeks, using cost-effectiveness analysis methods to evaluate the two treatment programs.

Results: After two weeks of treatment, the effectiveness in the control of blood sugar in CS II group was similar to the MDI group, with no significant difference (P<0.05) and the adverse reactions were similar. Costs in the CS II program (Yuan/person) was less than in the MDI program (1478.34 vs. 1620.46), with significant differences (P< 0.05). The cost-effectiveness ratios (C/E) were 15.07 in the CS II group, and 16.34 in the MDI group, with no significant difference (P>0.05). In order to further reduce the cost of CS II group as a reference, the incremental cost-effectiveness ratio (DeltaC/DeltaE) of the MDI group was 129.20.

Conclusion: Costs-effective of the CS II program was better than the MDI one in treating the newly hospitalized patients with type 2 diabetes, suggesting that CS II program might be a better choice for hospitals to carry on an intensive insulin therapy program.
