Clinical Hospital Emergency Triage & MIS

Multi-stage PostgreSQL ranking pipeline engineered for extreme high-stress reception desk conditions:

• Exact ICD-10 Code Normalization: formats like I63, i63.9, or I639 are instantly normalized and matched to clinical treatment pathways.
• Emergency Paramedic Acronyms: native mapping for field triage slang ('AMI', 'ACS', 'renal colic', 'acute stroke') without requiring exact diagnostic codes.
• websearch_to_tsquery Full-Text: robust handling of unformatted free-text clinical descriptions entered during ambulance delivery.
• pg_trgm Fuzzy Tolerance: automatic error forgiveness for high-velocity keyboard typos under urgent intake pressure ('insultt' → Ischemic Stroke).

In emergency trauma medicine, appointments are impossible: patients arrive unannounced and require instant attending assignment:

• staff_roster Engine: computes the exact attending specialist on active duty at this precise second across all 41 hospital wards.
• btree_gist Exclusion Constraints: mathematical hardware-level guarantee that no physician can ever be assigned overlapping emergency shifts.
• Flexible Duty Shift Rotations: native support for 8h, 12h, and 24h rotating duty shifts with instant emergency replacement coverage.
• Zero Paper Rosters: eliminates chaotic phone trees and delays finding who holds the active emergency pager.

Engineered specifically for the institutional scale of a major emergency care hospital complex:

• 41 Clinical Departments: emergency trauma surgery, vascular intervention, cardio-ICU, neurosurgery, toxicology, and hematology.
• 155 Real Board-Certified Physicians: verified medical directory with clinical qualifications, ward certifications, and surgical clearance levels.
• 317 Core Emergency Diagnoses: pre-indexed clinical clusters linking incoming symptoms to exact specialized departments and attending teams.
• Database-Level Row Security: strict PostgreSQL RLS policies securing confidential patient intake records across departments.

Saving lives by eliminating administrative friction during critical resuscitation windows:

• En-Route Admission Intake: receptionists initiate admission records the moment the field ambulance radios in initial vitals.
• Sub-80ms Departmental Routing: system pinpoints the target ICU bay, surgical suite, and attending physician in under 80 milliseconds.
• Surgical Team Pre-Alerting: specialized trauma teams are alerted and scrubbed in before the stretcher wheels through hospital doors.
• Electronic Case Registration: structured admission records preserve vital field paramedic anamnesis without manual re-entry errors.
