Authors' recomendations: With a probability of severe event of 24% for 6 months, a RO of 0.61 and a test execution of 0.28, the incremental cost per severe event avoided in the use of capillary ketone per is € 1.273. Drawing any conclusion about the cost-effectiveness is diffi cult since there are no data to estimate the quality of life of a patient type 1 with ketosis in Spain. If we consider that the health service might be willing to pay € 30,000 per additional healthylife year, and that a serious adverse event results in up to one week with very low quality of life, then the health service might be willing to pay up to € 577 for each event avoided. Under these assumptions, blood ketone tests would not be cost-effective for the base case. Blood ketone testing might be cost-effective under alternative scenarios, for instance in patients with a higher expected prevalence of severe events, or if a blood test strip cost less than € 1.5. These results indicate that determining the presence of ketonic bodies by capillary blood ketone testing is not cost-effective with patients having a good control of glucose and a low risk of ketosis. However, costeffectiveness may be greater in patients at a high risk or if the blood strip cost was lower. Moreover, the results are very sensitive to the frequency of ketonic body determination and the odds ratio of a severe event with capillary blood ketone testing versus urine testing.
