Framework
The Osolika
Doctrine
A structured operational framework for maritime medicine — built for the gap between hospital guidelines and shipboard reality.
Components
The 8 Doctrine Elements
Each element addresses a specific operational gap in maritime clinical practice. Together, they form a complete decision-making framework for the ship doctor working beyond the reach of hospital systems.
Osolika Deterioration Loop
A continuous 6-step reassessment cycle: recognize trend, stabilize, audit constraints, translate to command, document capability gap, and reassess the maritime day. Loops until the patient is stable or evacuated.
Osolika Endurance Index
A structured audit of the ship's clinical endurance: oxygen supply, available staff, drug inventory, diagnostic capability, weather conditions, and estimated time to definitive care.
Operational Readiness Score (ORS)
A 4-tier command status system: Green (within capability), Amber (stretched), Red (beyond capability), Black (imminent collapse). Translates clinical status into bridge-ready language.
Oxygen Clock
A countdown timer calculating remaining oxygen supply based on current flow rate and available reserves. When the clock runs out, clinical capability collapses. The single most critical maritime variable.
SBAR-M
Maritime-modified SBAR communication: Situation, Background, Assessment, Recommendation + Maritime constraint modifiers (distance, weather, resources, evacuation feasibility).
Capability Gap Language
Structured language for explaining why hospital-standard escalation is unavailable onboard. Documents what you cannot do, not just what you did. Protects the clinician medico-legally.
72-Hour Maritime ICU
The prolonged stabilization doctrine for when evacuation fails. Covers oxygen endurance planning, sedation rotation, vasopressor management, and staff fatigue cycles over 72 hours.
Nurse-Extender Model
A delegation framework for training and deploying non-nurse crew members during prolonged stabilization. Defines safe task boundaries, supervision levels, and handover protocols.
Dashboard
Operational Readiness Score
The ORS converts five clinical and environmental factors into a single command-ready status level. This is how the ship doctor communicates urgency to the bridge.

The Osolika Deterioration Loop
A structured reassessment cycle for managing clinical deterioration at sea. Each step feeds the next in a continuous operational loop.

Manifesto
The Ship Doctor Standard
- Stabilize first. Diagnose within your capability.
- Reassess continuously. The patient's trajectory matters more than the initial diagnosis.
- Audit your constraints. Oxygen, staff, drugs, diagnostics, weather, and time.
- Translate clinical risk into operational language the bridge understands.
- Document the capability gap — not just the treatment, but what you cannot do.
- Communicate early. The captain needs decision time, not last-minute crises.
- Know when onboard care is no longer enough.
- Prepare your handover before the patient needs one.
- Protect your team. Fatigue, isolation, and moral distress are real at sea.
- Every decision at sea carries the weight of distance. Respect the maritime multiplier.
