''This article is about Chronic Health in the context of the APACHE score, see [[Comorbid Diagnosis]] for info on the comorbidities we collect.''
This value is now derived from ICD10 diagnoses, see [[Change for Apache Chronic to ICD10 from separate variable]] for details.  


The Chronic Health field is stores information about specific chronic pre-existing underlying disease conditions. This value is used in conjunction with [[Admit Type for APACHE II]] to calculate the [[APACHE_Scoring_table#Chronic_Health_Score|Chronic_Health_Score]], one of the components of the [[Category:APACHE II | APACHE II score]].

Latest revision as of 10:32, 30 July 2025

This article is about Chronic Health in the context of the APACHE score, see Comorbid Diagnosis for info on the comorbidities we collect, and Charlson Comorbidity Index for the Charlson comorbidities that are also used for the Alert score.

This value is now derived from ICD10 diagnoses, see Change for Apache Chronic to ICD10 from separate variable for details.

Implementation

ICD10

We are moving to derive this concept from APACHE Comorbidities in ICD10 codes.

Change log

  • 2022-02-17 - decided to stop collecting this and apply Change for Apache Chronic to ICD10 from separate variable
  • 2022-02-09 - Julie, Tina and Allan discussed Julie's most recent analysis of this; there are still many differences in dx vs chronic, with higher and lower counts for different components. Allan quotes a paper that acknowledges this difference in count, but that the Apache score ends up similar. Question raised: is the saving of time in no longer collecting this as a field worth the loss of accuracy.
  • 2021-04-22 - preliminary analysis of how deriving this from ICD10 would compare with previous manual collection; many differences; Tina emailed Allan and Julie, more to come
  • 2021-04-19 - Added Drug-induced immunosuppression since that component of this code was not previously collected comprehensively
  • 2021-03-11 - The list of drugs is at Template:List of immunosuppressive drugs.
  • 2021-02-22 - AG sent email to Julie and Tina to get back to this change.
  • 2018-11-28 - AG confirmed that this is an option

Legacy

  • when sent for import into TMSX and MedTMS the chronic health score was translated into yes or no; when we moved to Centralized_data.accdb these were imported as "0HasChronic"
  • the fields were made into a pick list of 9 items that belong to one of the five APACHE II Chronic Health categories because Medicine wanted to use both APACHE II and SAPS II on Medicine patients. SAPS II and APACHE II scored these same chronic health items differently. SAPS is no longer collected.
