Identifies patient medication histories - medication history, drug or prescription history, current medication lists, dispensing records and medication reconciliation - when the phrase sits with populated patient identifiers and medication lines (drug, dose and frequency). Protected health information under applicable data protection regulations.

Type: regex
Engine: boost_regex
Confidence: medium
Confidence justification: Medium: enforce tiers need a populated patient identifier, and 85 also needs a dose/frequency medication line plus pharmacy or clinical evidence. Formularies, clinical guidelines and medicines information can carry the phrases and dose lines, but not a patient field, so they stay at 65.

Known false positives

Medical terminology in health education materials, research publications, clinical guidelines, or public health documents without patient-specific data. Mitigation: Require corroborative evidence keywords confirming patient context. Look for co-occurrence with patient identifiers such as medical record numbers or dates of birth.
General wellness and fitness content using medical vocabulary without constituting protected health information. Mitigation: Layer with patient identifier patterns or healthcare-specific document structure detection to distinguish clinical records from general health content.
