Acute Renal Insufficiency

Guideline

• A Rise >100 mmol from baseline over 24 hours'
• a patient is not on chronic hemodialysis or peritoneal dialysis

• I don't think that just having a creatinine of >250 should automatically mean ARI. This could be the patient's baseline and therefore is a chronic issue. My opinion is to only use the rule of >100 mmol over baseline over 24 hours for acute renal insufficiency (without dialysis), or use ATN if this is documented. --LKolesar 07:13, 2014 October 8 (CDT)
  • Are we to change what we have being doing for over 10 years ?--PStein 09:54, 2014 October 15 (CDT)
    • I am just putting my opinion here, if any changes are done they will have to go through the task group first.--LKolesar 11:28, 2014 October 15 (CDT)
      • I always check what the pts baseline creatinine was prior to admission if the pt had chronic renal insuffiency and creatinine was 250 last admission I will code as mod CRI if the present creatinine was say 350 I will code acute RI in admits and CRI in comorbids ( acute on chronic )If the creat was the same as last admission say 250 and pt has CRI I only code in comorbids because it is not acute.-Shirley Kiesman
        • This is what I do also. This makes sense to me, not arbitrarily putting a value of >250 as acute renal insufficiency.--LKolesar 17:29, 2014 October 15 (CDT)
          • remove the 250 value from the definition. ~~Judy Kublick oct 16, 2014
  • I don't actually see a 250 in the core definition above... Ttenbergen 12:11, 2015 March 30 (CDT)
  • You are right Tina, not sure if this had been changed since these comments were made (IN OCT 2014)or if comments were made in error. Just need to clean up the comments here I think. --LKolesar 12:24, 2015 March 30 (CDT)
