Abstract
BACKGROUND: Type 2 diabetes (T2D) is a common, potentially disabling, and costly chronic condition that requires consistent management. In 2008, Norway introduced a national checklist outlining services to include in an annual T2D exam, along with a reimbursement code for general practitioners (GPs) to bill upon completing it. This study investigates whether GP adoption of the checklist improves adherence to recommended services for T2D patients. METHODS: To investigate the impact of GP checklist adoption, we use Norwegian registry data from 2006 to 2021 and apply two difference-in-differences (DID) methods that account for staggered adoption timing: the two-way fixed effects (TWFE) estimator and Callaway and Sant'Anna's DID method for variation in exposure timing (CSDID) (Callaway B. et al., J Econom 225:200-30, 2021). RESULTS: We find that installing the electronic form has modest effects on the use of some recommended procedures. CONCLUSIONS: Our study suggests that using the electronic form can have a positive effect on recommended services. However, the modest impact indicates that installing the form does not necessarily translate into its active regular use.
