Often existing health economic models are applied in other countries and settings than those where they were developed. This practice requires assessing the transferability of a model developed from one setting to another. We evaluate the transferability of the {MICADO} model, developed for the Dutch 2007 setting, in two different settings using a range of adjustment steps. {MICADO} predicts micro- and macrovascular events at the population level. Methods {MICADO} simulation results were compared to observed events in an Italian 2000–2015 cohort (Casale Monferrato Survey [{CMS}]) and in a Dutch 2008–2019 (Hoorn Diabetes Care Center [{DCS}]) cohort after adjusting the demographic characteristics. Additional adjustments were performed to: (1) risk factors prevalence at baseline, (2) prevalence of complications, and (3) all-cause mortality risks by age and sex. Model validity was assessed by mean average percentage error ({MAPE}) of cumulative incidences over 10 years of follow-up, where lower values mean better accuracy. Results For mortality, {MAPE} was lower for {CMS} compared to {DCS} (0.38 vs. 0.70 following demographic adjustment) and adjustment step 3 improved it to 0.20 in {CMS}, whereas step 2 showed best results in {DCS} (0.65). {MAPE} for heart failure and stroke in {DCS} were 0.11 and 0.22, respectively, while for {CMS} was 0.42 and 0.41. Conclusions The transferability of the {MICADO} model varied by event and per cohort. Additional adjustments improved prediction of events for {MICADO}. To ensure a valid model in a new setting it is imperative to assess the impact of adjustments in terms of model accuracy, even when this involves the same country, but a new time period.}, journaltitle = {Acta Diabetologica}, shortjournal = {Acta Diabetol}, author = {Emamipour, Sajad and Pagano, Eva and Di Cuonzo, Daniela and Konings, Stefan R.
