Fixes a data issue with length of stay and survival duration being filled in
across 2 columns. and missing last observation dates so that we can calculate
survival censoring consistently in other data sets.
Usage
derive_survival_times_pneumo(df, v, ...)
Arguments
- df
the dataframe.
- v
the value set. usually precomputed by the augment framework the value
set can be explicitly supplied with v = get_value_sets(df)
- ...
ignored
Details
Calculates:
A consistent length of stay - shortest of length of stay and 30 day and 1 yr survival duration
A consistent uncensored time to death - shortest of 30 day and 1 yr survival duration
A consistent time to last observation
