preprocessRecord

public void preprocessRecord(HomeHealthRecordIF record,
                             HomeHealthRecordValidatorIF validator)

This preprocesses the record to adjust the diagnostic groups based on the presence of an Ulcer or Diabetic Ulcer on the record. Pseudo code lines: 1530 thru 1575

Specified by:

preprocessRecord in interface HomeHealthScoringModelIF

Parameters:

record -

validator -

Calculate maximum possible score for each of the 18 diagnoses to support choice of scoring variable when an etiology and a manifestation are both NRS casemix variables. special case for primaries and ulcers Pseudo code lines: 1521 thru 1574

Parameters:

record -

validator -

Returns:

int array with score per diagnosis

determinePrimaryDiagnosis

public void determinePrimaryDiagnosis(HomeHealthRecordIF record,
                                      HomeHealthRecordValidatorIF validator,
                                      int[] icd9Points)

Parameters:

record -

validator -

icd9Points -

resolveEtiologyManifestationContention

public boolean[] resolveEtiologyManifestationContention(HomeHealthRecordIF record,
                                                        HomeHealthRecordValidatorIF validator,

Cycle through all diagnosis positions with points. Drop points for non-initial occurrences of any NRS diagnosis groups. Resolve contention within etiology/manifestation pairs when both are casemix diagnoses in different diagnosis groups by retaining the DG with higher score unless that DG has already earned points via a previous occurrence. Any points lost at this point are not recaptured Pseudo code lines: 1683 thru 1762

Parameters:

record -

validator -
