Clinical pathways are often designed for similar patients, but traditional classification systems like the Clinical Coding System (CCS) show a strong relationship when focusing on principal procedures. Further research is needed to refine this connection.

Area of Science:

  • Healthcare Management
  • Medical Informatics
  • Clinical Pathway Optimization

Background:

  • Clinical pathways are typically developed for homogeneous patient groups.
  • The study investigates the applicability of traditional patient classification systems for clinical pathway categorization.

Purpose of the Study:

  • To examine the utility of patient classification systems in classifying clinical pathways.
  • To determine the most effective classification system for aligning with clinical pathway structures.

Main Methods:

  • Analysis of 13 clinical pathways involving 412 patients.
  • Evaluation of three classification systems: International Classification of Diseases, Ninth Revision (ICD9-CM), Clinical Coding System (CCS), and All-Patient Redefined Diagnosis Related Groups (APR-DRG).

Main Results:

  • ICD9-CM and CCS categorization showed significant variation.
  • Restricting to principal codes, CCS demonstrated a strong, near-homogeneous relationship with clinical pathways.
  • All-Patient Redefined Diagnosis Related Groups (APR-DRG) were difficult to assess due to secondary procedure corrections.
  • Risk Of Mortality (ROM) categorization was more homogeneous than Severity Of Illness (SOI).

Conclusions:

  • Patient groups within clinical pathways are generally heterogeneous.
  • The Clinical Coding System (CCS), when restricted to principal procedures, shows the strongest relationship with clinical pathways.
  • Further research is recommended to refine the identified relationship between CCS and clinical pathways.
