Objectives
To determine the effect of the length of the lookback period on the incidence estimates of heart failure (HF), chronic liver disease, and HIV/AIDS using a claims database.
Conclusion
The choice of the length of the lookback period for estimating incidence is an important methodological point. Depending on the disease and the length of the lookback period, the overestimation of incidence estimates varies.
