The engine, inverted
By factor
Below poverty level
drives 4 barriersHousehold income
- Financial toxicity / out-of-pocket burdenHigh
Below poverty, even modest out-of-pocket costs force impossible trade-offs that can derail treatment
- Equity / disparity riskHigh
Low income stacks travel, lodging, time-off, and coverage hurdles that each thin the odds of finishing care
- Housing insecurity / relocation burdenModerate
On a low income, paying for weeks of lodging away from home is usually out of reach without help
- Travel & lodging burdenWatch
Below poverty, front-loaded travel and lodging costs are often simply unaffordable without assistance lined up first
Limited health literacy
drives 3 barriersHealth-system navigation
- Equity / disparity riskHigh
Harder to grasp eligibility, ask the right questions, and self-advocate — so these patients are identified and referred less often
- Health-literacy / navigation-complexity burdenModerate
The pathway spans dozens of visits, forms, and authorizations; without hands-on navigation, steps get missed and patients fall behind
- Language & communication barrierWatch
Dense medical explanations may not land, so key instructions and warning signs can be missed unless teach-back is used
Rapidly progressive disease
drives 3 barriersDisease pace
- Late referral / progression before treatmentHigh
Fast-moving disease can outrun the refer-and-work-up timeline, so any delay risks losing the treatment window
- Eligibility / patient-selection hurdlesWatch
Rapid progression can erode fitness mid-work-up, so someone eligible today may not be by the time they are assessed
- Manufacturing / collection & vein-to-vein riskModerate
The 2–8 week manufacturing wait is hard to survive when disease is moving fast, which makes strong bridging therapy critical
Hesitancy / mistrust
drives 2 barriersExpresses hesitancy, fear of toxicity, or mistrust
- Awareness, understanding & hesitancyHigh
Fear of toxicity or mistrust can lead to hesitation or outright refusal even when the patient is a strong candidate
- Health-literacy / navigation-complexity burdenModerate
Mistrust can cause hesitation, missed visits, or declined steps that stall the whole process
New to cell / gene therapy
drives 2 barriersFamily understanding of CAR-T
- Awareness, understanding & hesitancyHigh
New to CAR-T, the family may over- or under-estimate risk and benefit, which makes decisions harder and slower
- Health-literacy / navigation-complexity burdenModerate
Brand-new to cell therapy, the family has a lot to absorb quickly just to keep decisions on schedule
Uninsured / self-pay
drives 2 barriersInsurance
- Insurance coverage & prior-authorizationModerate
With no plan in place there is no payer to authorize — coverage has to be secured before anything else can proceed
- Financial toxicity / out-of-pocket burdenHigh
Uninsured, the six-figure therapy plus surrounding care is unaffordable without emergency coverage or assistance
Caregiver availability uncertain
drives 1 barrierDedicated caregiver (~30 days)
- Caregiver & psychosocial clearanceHigh
An unconfirmed caregiver can hold up psychosocial clearance until a concrete, named plan is in place
Caregiver would lose income
drives 1 barrierCaregiver & work
- Caregiver & psychosocial clearanceHigh
If the caregiver can't take ~a month of leave without losing income, the required round-the-clock coverage can fall through
Little / no savings
drives 1 barrierFinancial cushion
- Financial toxicity / out-of-pocket burdenHigh
With little savings, one unexpected bill or lost paycheck can halt participation mid-course
Lives alone
drives 1 barrierLiving situation
- Caregiver & psychosocial clearanceHigh
Living alone means no built-in caregiver, so one has to be recruited to meet the requirement
Minority race / ethnicity
drives 1 barrierminority
- Equity / disparity riskHigh
Documented referral bias and trial under-representation mean minority patients reach CAR-T less often at each step of the path
Not yet referred
drives 1 barrierCurrently managed at
- Late referral / progression before treatmentHigh
No referral is moving yet — the clock toward a CAR-T center hasn't started
Referring team unfamiliar with CAR-T
drives 1 barrierReferring team & CAR-T
- Late referral / progression before treatmentHigh
A team unfamiliar with CAR-T may not spot candidacy or know when and where to send the patient
Relies on others / transit
drives 1 barrierTransportation
- Transportation barrierWatch
Depending on others or transit makes frequent, time-sensitive visits fragile — a missed ride becomes a missed step
Unstable housing
drives 1 barrierHousing
- Housing insecurity / relocation burdenModerate
The protocol needs a stable home base near the center; unstable housing can make that stretch impossible to arrange
Would lose income during treatment
drives 1 barrierIncome during treatment
- Financial toxicity / out-of-pocket burdenHigh
Weeks away from work with no paid leave cut household income at exactly the moment costs are spiking
