====== Early Treatment Pathways in Chronic Disease ======

<WRAP box justify round>

**Objective:** The objective of this study is to characterize the prevalence of different treatment pathways within the first year of drug initiation for three chronic diseases: Hypertension, Type II Diabetes, and Depression. 

**Rationale:** While numerous treatment guidelines exist for chronic conditions, there is a paucity of data on the real-world treatment pathways.  A recent OHDSI study explored treatment pathways for chronic conditions based on 3 years of drug exposure.  Additional interest exists for looking at treatment in the early phases of a disease, where switching may often occur.  Additionally, focusing the analysis on a narrower timeframe post-initiation will increase the number of eligible patients and potentially provide additional insight into these pathways.
