Defined in:

Overview

Filters a set of observations using a specific set of OBX codes. The snapshot is stored on the hd_patient_statistics table - i.e. it represents the state of the patient’s pathology *at the time the hd_stats row is created*. So for an hd_stats row for say Patient X in the month of April 2018, the pathology_snapshot is a frozen snapshot of their pathology at 30/4/2018 23:59 TODO: de-dupe this with the other FilteredObservationSet in Letters::?

CODES =

These are the codes for the results we want to store in hd_patient_statics.pathology_snapshot - we are only interested in these results. They will be used for instance in reporting_hd_overall_audit
