How the TBL Travel Risk Score Works (PPRR)

What this tool is (and isn’t)

A fast pre-trip checker that blends your baseline stability, trip complexity, and safety-net readiness into one score, then generates Predict • Protect • Rescue • Restore actions and a checklist.

Not a medical device.
Not diagnosis, treatment, prescribing, or clinical monitoring.
Not fit-to-fly or travel clearance.
Not real-time crisis support.

Safety boundaryIf you are urgently unwell, noticing new or rapidly worsening symptoms, or your clinician has advised against travel, pause and seek in-person care rather than relying on this tool.

The scoring model (high level)

Total risk score (0–100)
A risk level label
Three sub-scores:
- Health baseline (50%)
- Trip complexity (30%)
- Safety-net readiness (20%)

Why these weights: baseline stability tends to dominate flare risk. Complexity can amplify triggers. Safety-net readiness is damage control when plans break.

How the math works

Each question is scored from 0 to 3. For each domain, the tool calculates an average, converts it to a percentage, then applies the domain weight.

Domain % = (domain average ÷ 3) × 100
Total score = (Health % × 0.50) + (Trip % × 0.30) + (Readiness % × 0.20)

The score is deterministic (rule-based). If you change inputs, the score changes in a predictable way.

What inputs go into the score

Trip basics: travel mode, duration, changes, time-zone shift, destination climate

Health & support: pain control, flare frequency, mobility, comorbidities, medication complexity, sleep stability, last trip outcome, self-management skills

Safety-net readiness: documents, insurance and emergency plan, assistance booked, accommodation accessibility, contingency budget, support network and communications

How to interpret your result

LOW0–24

What it usually means: Generally travel-ready with routine buffers.

What to do next: Proceed, but harden the trip.

MILD25–39

What it usually means: Some friction expected, usually manageable with planning.

What to do next: Add 1–2 buffers, then recheck.

MODERATE40–54

What it usually means: Meaningful flare risk unless you reduce load or strengthen buffers.

What to do next: Proceed only if you can make a meaningful load-reducing change, then recheck.

HIGH55–74

What it usually means: High crash likelihood without changes.

What to do next: Do not lock in non-refundable costs until you reduce complexity and strengthen safety net.

VERY HIGH75–100

What it usually means: A pause-and-redesign signal for the current plan.

What to do next: Postpone or redesign to a minimum viable trip.

Level	Score band	What it usually means	What to do next
LOW	0–24	Generally travel-ready with routine buffers.	Proceed, but harden the trip.
MILD	25–39	Some friction expected, usually manageable with planning.	Add 1–2 buffers, then recheck.
MODERATE	40–54	Meaningful flare risk unless you reduce load or strengthen buffers.	Proceed only if you can make a meaningful load-reducing change, then recheck.
HIGH	55–74	High crash likelihood without changes.	Do not lock in non-refundable costs until you reduce complexity and strengthen safety net.
VERY HIGH	75–100	A pause-and-redesign signal for the current plan.	Postpone or redesign to a minimum viable trip.

Top drivers

Baseline instability
High complexity
Weak buffers

Your job is not to fix everything. Change the top 1–3 drivers that give the biggest risk reduction for the least extra strain.

What PPRR means

Predict: identify what usually triggers you on this trip.
Protect: add buffers, reduce complexity, and set ceilings.
Rescue: pre-decide what you do if symptoms spike.
Restore: a post-trip re-entry plan so recovery is protected.

FAQ

Does a higher score mean I cannot travel?

No. A higher score means your current plan has higher expected friction and flare risk unless you reduce trip load or strengthen buffers.

Can this tool clear me to fly or travel?

No. This tool is not a fit-to-fly or travel clearance assessment. It is educational planning support only.

Why do safety-net items affect the score?

Because when plans break, buffers reduce harm such as delays, missed medication timing, inaccessible rooms, inability to rest, or lack of an emergency plan.

Can I lower my score without changing my health?

Often yes—reduce trip complexity and strengthen readiness, then rerun the tool.

Does TBL see my answers?

By default, no. Inputs stay on your device unless you intentionally share them.

Final step

Most people do best when they check the score, change the top 1–3 drivers, then rerun the tool before deciding.
