If a hospital would like to undertake a study on economic evaluation, what threshold should the hospital use? Since threshold is applied on a national level, can the hospital simply use ACER instead of ICER? Many

It depends on the objective of hospital-based HTA. For example, to inform hospital budget investment and what the hospital will charge patient, or to inform hospital budget investment and the hospital will charge to the national health insurance, or to inform central government investment to hospitals etc. Each objective should have different approach and, maybe threshold.
