Existing conditions upon admission #235

Closed luoyuanlab closed 7 years ago

luoyuanlab commented 7 years ago

Hi, I want to find if a patient is admitted with Heart Failure. In particular, I do NOT want to include patients who developed Heart Failure during ICU admission. What is a reliable way of doing this?

Best, Yuan

I would recommend the comorbidities using algorithms from the AHRQ (based on a publication by Elixhauser et al.) or an algorithm by Quan et al.

Roughly, these use (i) ICD-9 billing codes to identify the condition and (ii) DRG codes to ensure the condition was a comorbidity and not the primary reason for hospitalization. These comorbidities are determined on hospital discharge.

Changing the scenario a little bit (during -> before), but the answer may be different, please let me know if I should open another issue. I want to find if a patient is admitted with Heart Failure. In particular, I do NOT want to include patients who developed Heart Failure before ICU admission. What is a reliable way of doing this?

Thanks, Yuan

Our best way is using comorbidities. See #290 for some discussion.
