Patient Reception, MRN Registry & Triage

Patient Identification & MRN Management#

Every patient registering at the healthcare facility is assigned a permanent, unique Medical Record Number (MRN) managed by hms.patient.

Core Patient Attributes#

• MRN Sequencing: Automated sequence generated per health facility (e.g., MRN-AA-2026-00451).
• Demographics & Contact Details: Full legal name, date of birth, gender, marital status, emergency contact, kebele/woreda address.
• Medical Baseline: Recorded blood group (e.g., A+, O-), chronic conditions, known drug allergies (e.g., Penicillin, NSAIDs), and prior surgeries.

Triage & Vital Signs Measurement#

Before advancing to a consulting physician, outpatient reception routes the patient to the nursing triage station where vital signs are captured on hms.vital.signs:
