Detailed Description

This macro computes and optionally categorizes requested risk scores.

• Break out CaresettingPrincipal into Caresetting and Principal.
  
• Process wildcards for diagnoses.
  
• Break down meds file in procedures and diagnoses for efficiency.
  
• Adjust RiskFromAnchor and RiskToAnchor values for computation.
  
• Get list of index dates and keep variables required for anchoring.
  
• Loop through the different requested risk scores.
  • In addition to the basic riskscores available in the lookup file, custom riskscores can also be computed:
    • CCI
    • ADSCI
    • FRAILTY
    • HASBLED
    • CHA2DS2VASC
    • OBSCOMORB
    • PEDCOMORB
  • Process risk scores definition inputfile.
  • Determine if PX, DX, RX, DM (sex and age groups) and IN (intercept) codes exist in the lookup table.
    
  • Assign intercept value (if applicable).
  • If diag, proc, and drug codes exist in lookup table pull all claims of with a code of interest for index patients.
    
  • If demographic sex codes exist in lookup table assign weight according to sex.
  • If demographic age group codes exist in lookup table assign weight according to age group.
    
  • Compute score for all patient/IndexDt combinations.
  • Assign risk score categories (if any).
  • Merge scores data.
    
• Update master file with scores data.
  
• Restore sorting as it was prior to scores computation.
  

Program inputs

• dplocal.&RUNID._&DATA. (Dataset containing one record per individual per index date for every cohort specified in the CIDA module run.)
• work.riskscorefile (Dataset containing unique risk scores.)
• work.riskscorescodes (Dataset containing risk score codes for raw extraction.)
• worktemp._riskscores_rx (Dataset containing drug claims for scores computation.)
• worktemp.riskscoresmeds (Dataset with separated diagnosis and procedure claims for scores computation.)

Program outputs

• dplocal.&RUNID._&DATA. (Dataset containing the requested risk scores and optional risk score category.)
