Beyond the Lab
Access failure does not begin or end at specimen collection.
Access Before Analysis began with a laboratory question: What happens to the child for whom an ordered test never produces a specimen?
That question raises a larger one.
How often does healthcare measure what happens after successful access while failing to measure the patients who never successfully reach, complete, or carry forward the intended care?
The laboratory is our starting point—not the boundary of the question.
Care Intended → Care Accessed → Care Prepared For → Care Attempted → Care Completed → Care Followed Through
At every transition, a child can disappear from the outcome we eventually measure.
What was supposed to happen?
Did it happen?
If not, why not?
What changed before the next attempt?
Procedural Access
A procedure begins before the procedure.
A child may physically arrive for care and still lack meaningful access to it.
Preparation may rely on rapid verbal explanation, abstract language, unfamiliar touch, unexpected sensations, multiple instructions, transitions, or an expectation of immediate cooperation.
When a procedure cannot be completed, how much of the failure belongs to the child—and how much belongs to the way access was designed?
Blood collection • Vaccination • Vitals • Physical examination • Imaging • Dentistry
Access Before Analysis begins by studying this phenomenon in pediatric laboratory medicine. Whether the same access mechanisms generalize across other procedures is an important research question—not an assumption.
Accommodation Missingness
When the healthcare system already knows what works—and loses it.
A child successfully completes a procedure after the team learns that they need a quiet room, visual preparation, additional processing time and a caregiver beside them.
Six months later, another department starts from zero.
Accommodation missingness occurs when useful information about a patient's communication, sensory, procedural or support needs is known somewhere in the care history but is unavailable, inaccessible, poorly documented or not operationalized when care is delivered.
Never captured → Buried → Not transferred → Not acted upon
An accommodation cannot improve access if the person who needs to implement it never receives it.
Communication | Sensory environment | Procedural support | Caregiver role | Strengths | Relevant safety | Arrival/follow-up
What worked before — procedure + date + context

Care Completion Barriers
“Not completed” is not an explanation.
Access Before Analysis proposes capturing the barrier to completion, rather than treating the patient as the barrier.
Clinical/procedural
Sensory/environment • Communication • Trauma/anxiety • Procedural access
Practical
Scheduling/work • Transportation/distance • Childcare/family demands
System
Cost/insurance • Language/interpreter • Service unavailable/waitlisted • Unable to contact
Choice
Family chose not to proceed
Always available
Other — caregiver's words
Don't document the person as the problem. Document the barrier to completion.
Behavior Is Data — But It Is Not a Diagnosis
Behavior can communicate that something has changed.
For children who cannot consistently describe pain, illness, fear, sensory distress or other internal experiences verbally, changes in behavior or participation may contain clinically meaningful information.
Behavior should prompt curiosity—not automatically become the explanation.
Incomplete Care Must Travel
An encounter can end before the intended care is complete.
A child leaves an ED without tolerating ordered imaging.
A blood specimen cannot be obtained.
A procedure is deferred.
Medication could not be administered.
The chart can close while the clinical need remains open.
Encounter closed ≠ care completed.
Why Begin With the Laboratory?
Because laboratory medicine gives us an unusually visible boundary.
No specimen → no analysis → no result.
Yet the absence of a result does not tell us why the diagnostic process stopped.
Did the child never arrive?
Could the child not tolerate the environment?
Was preparation inaccessible?
Was collection attempted and abandoned?
Were previously successful accommodations unavailable?
Was transportation the barrier?
Did the family choose not to continue?
Was the service unavailable?
The missing result is visible. The reason it is missing often is not.
Access Before Analysis begins by making that missingness measurable.
