Isotretinoin may cause liver failure, therefore the patient's blood levels should be regularly tested. [9] It is known to cause birth defects due to in-utero exposure because of the molecule's close resemblance to retinoic acid, a natural vitamin A derivative that controls normal embryonic development. It is associated with psychiatric side ...

Subsequent studies have adapted the comorbidity index into a questionnaire for patients.
The reticulocyte index (RI) should be between 0.5% and 2.5% for a healthy individual. [8] RI < 0.5% with anemia indicates maturation disorder, meaning loss of red blood cells, but also decreased production of reticulocytes (i.e., an inadequate response to correct the anemia) and therefore red blood cells. [2]
The Revised Cardiac Risk Index (RCRI) is a tool used to estimate a patient's risk of perioperative cardiac complications. The RCRI and similar clinical prediction tools are derived by looking for an association between preoperative variables (e.g., patient's age, type of surgery, comorbid diagnoses, or laboratory data) and the risk for cardiac complications in a cohort of surgical patients ...
