Detailed Description

This macro creates the exposure episodes.

• For type 1:
  • Create episodes.
  • Trick ADate and ExpireDt to mimic an episode and type 2 structure.
• For other types, except type 3:
  • EpisodeEndDt values are assigned to adjust for maximum episode duration prior to PtsMasterlist merge. If maximum episode duration isn't specified, enrollment end is used.
  • Create claim based episodes (as-treated).
    • Claim based episodes are built using all claims with the exception of when MINCUMDOSE/MINCFDD/MAXCFDD is specified, in which case build episodes starting from claims that meet _pov1.
  • Summarize episode level details.
  • For type 2:
    • When minimum cumulative dose or min/max current filled daily dose specified, set EpisodeStartDt to IncidenceClaimDate and remove all claims where IncidentClaimDate not set.
  • Adjust EpisodeEndDt for episode extension that overlap the next episode.
  • For type 2 and 5:
    • Truncate (potentially extended using episode extension) episodes with FUT.
• Assess cumulative dose per episode and extract ADate (for censoring) when MaxCumDose is reached.

Program inputs

Program outputs
