OVERVIEW
PreSync pulls together prescriptions, reports and pharmacy records into one current list of the medicines.
THE PROBLEM
No one holds the full, current list of an older person's medicines. It is scattered across doctors, pharmacies, hospitals and memory.
WHAT I DESIGNED
An app that builds that list from ABHA records, pharmacy bills (simulated) and photos. Nothing is added until a person confirms it.
HOW I TESTED IT
Eleven people, three tasks, one clickable prototype, then the System Usability Scale.

WHY THIS EXISTS
What is he actually supposed to be taking?
Right now. Nobody in the room could say.
My grandfather, 84. Admitted in a city he was only visiting, with every record he had on paper, in another town.
Never prescribed
Strips bought over the counter
No date on it
Still being taken, or not?
Paper only
Exists nowhere else
Multiple prescriptions
Not one sheet is the whole list

Apps keep the papers, or keep a list.
None joins them into one current list.
The apps were not the whole story.
India already has a national health ID.

WHAT I FOUND AND WAS STILL MISSING
ABHA fixes a real problem. A record that used to stay in one hospital can now travel with the person. But only about half the registered facilities can link a visit, and there is about one record per ABHA number so far. What travels is a document, not a list.
The data could only take me this far.
So what is actually happening inside homes?
I sorted the apps by two questions: where do medicines come from, and
is the result one current list or a folder?
None I found reached the fourth corner.
A doctor adds a medicine
Does anyone check it against the others?
A strip is bought at a counter
Where is it written down or doctor hear of it?
An old prescription is kept

WHAT I HEARD
I asked families how they keep track.
Here is what came up.
I spoke with 2 people who manage their own medicines and 5 who manage them for someone older in their family, about their last appointment, hospital stay and counter purchase.

01
Nobody checks one doctor against another.
Each prescription is trusted on its own. No one looks at all of them together.
02
The same medicine came home twice.
Two doctors, two brand names, one molecule. The family could not tell they were the same.
03
The list is recited, not read.
At appointments, medicines were listed from memory, or a bag of strips was handed over.
04
One person holds it all together.
When the medicines belonged to someone older, another family member did the tracking.
05
A counter strip rarely reaches the doctor.
Painkillers and antacids bought without a prescription were left out when medicines were listed.
06
Old prescriptions are kept, stopped or not.
Old sheets were kept. Nothing marked which medicines had stopped.

SYNTHESIS
Everything went on one wall,
then I sorted it by where it happens.
Published research, what I heard, and the apps I tried, on one wall. Each note keeps a mark for where it came from, so a finding from one family never passes for a national number.
published research
what i saw and heard
existing tools
AT THE DOCTOR
Many medicines, many doctors. Each prescription shows only part of the list.
People rely on memory, and recite the list at visits sometimes.
The same molecule came home under two brand names.
Medicines taken together can interact, sometimes severely.
AT THE COUNTER
Counter medicines leave no prescription, and get left out.
Each pharmacy keeps only its own sales.
AT HOME
Prescriptions pile up as paper and photos, not a list.
Old prescriptions stay, even after a medicine stops.
One person does all the tracking, often a family caregiver
List apps mostly need everything typed in.
When the person who tracks is away, the list stays behind.
IN HOSPITAL
In one hospital, mismatches came at admission and peaked at discharge.
IN THE RECORDS
ABHA links each visit as a separate record, not as one list.
Record apps file documents, but none I found joins them.
The ABHA app I tried had no family profiles.
CORE PROBLEM
No one holds the current list.
Each place keeps its own part. Nothing I found joins the parts into one list for the person and their doctor.
Only about half of registered facilities can send a record at all.
Counter sales come with no advice on side effects or allergies.

WHO THIS IS FOR
The list belongs to the person taking the medicines.
It is often kept by someone else.
Many older adults take five or more medicines, and a family member often helps keep track of them. Others manage their own medicines, so both have to work.
THE PERSON ON THE LIST
Takes the medicines.
The list is theirs.
THE PERSON KEEPING IT
Keeps track, often for someone older.
PRIMARY USER
THE DOCTOR
Reads the list at visits.
Never logs in.
Sometimes the same person
SO THE LIST HAS TO
01
Belong to the person taking the medicines.
02
Be kept by whoever looks after them.
03
Work the same when that is one person.

PROBLEM STATEMENT
The person keeping track of the medicines, often a family caregiver, needs one current list. Each doctor, counter and hospital keeps its own part, and nothing joins them, so a change, a repeat or a clash is easy to miss.
How might we help the person keeping track hold one current list, from the papers, records and purchases that already exist?

WHAT A SOLUTION HAS TO DO
01
Take in
From the places a medicine comes from paper, records, counter.
02
Ask first
Nothing joins the list until a person confirms it.
03
Check
Look across for repeats and clashes, and leave the decision to a doctor.
04
Hand over
Give the doctor the list, so it is not recited.
05
Belong
To the person taking the medicines, kept by whoever looks after them.

Ideation
Two answers looked obvious.
Neither one survives a real house.
01
Let the person keep the list.
Every app that holds a list asks to be typed in, or photographed. A list nobody is paid to maintain stops being updated in the first tired week, and the tired weeks are the ones that matter.
02
Build it on ABHA alone.
Real, government backed, and only ever as complete as national adoption. 2.72 lakh of 5.33 lakh registered facilities actually run software that can write to it.

So the question stopped being where to keep a list, and became where a list could come from.

THREE WAYS IN
No single route reaches everybody.
So typing stays, but only as the last resort.
The map says medicine arrives from too many directions for any one rail to catch it. So the list fills three ways, stacked. The two automatic routes each depend on a condition somebody else controls. The one at the bottom depends on nothing, so it is always there when the other two cannot reach.
The billing software route
where the counter runs connected software
costs the person a number, once
counters not running connected software
not reached by this route
arrives with the sale, then waits to be sorted
The ABHA route
where the pharmacy is in the facility registry
costs the person a consent, once
pharmacies not registered on the rail
not reached by this route
fetched with the person’s consent
Typing it in
everywhere: cash, over the counter, any shop at all
costs the person one entry, by hand
typed in by hand, as a last resort
Everything above the bottom band removes work.
Band widths show which routes depend on a condition somebody else controls. They are not measured market share, because nobody publishes that.

WHAT THIS CHANGES
The list stops being something you keep.
It becomes something that arrives.
This is what the three routes are for. Not a feature list, four specific things that are broken today and are not broken once the list fills itself.
TODAY
ONCE THE LIST ARRIVES
Over the counter medicines
A strip of painkillers never gets logged by hand, so it is simply missing from the list.
Arrives with the sale, and waits for the person to confirm it.
The caregiver
Has to ask what was bought, and is told whatever somebody remembers.
Sees the purchase without having to ask anyone.
Duplicates and interactions
Cannot be caught reliably, because the list was never complete.
Can be caught, because the list is more complete.
Entering things by hand
Every medicine, by hand.
Only the ones that did not arrive.

Prescription, synced.
One current list of what a person is taking, assembled from records that already exist. Nothing on it is final until a person confirms it.

IT ASKS BEFORE IT ADDS
Anything it is unsure of waits for a person to confirm. Nothing is decided for them.
IT HANDS OVER
One summary, grouped by condition, ready for the next doctor.

WHY the counter already asks for this number. It is what later lets a purchase find the right person.
WHY one person holds the list together, and it is usually not the patient (insight 04).

Skip on every card. The four cards say what the app does, and none of them blocks setup.

Scan once. Stay clear.

Know what changed.

Ready for any doctor.
One number, and a code.
The same mobile number a pharmacy counter asks for, which is what later lets a purchase find the right person.
WHY the counter already asks for this number. It is what later lets a purchase find the right person.

Verify the number
Setup asks about the patient.
Name, age, relationship and conditions describe the person whose medicines these are, not whoever is holding the phone. “Myself” is on the list too.
WHY one person holds the list together, and it is usually not the patient (insight 04).

ABHA is offered before the first medicine is added.

WHAT I LEARNED
What this project taught me,
beyond this one app.
01
Look for what is already being written down.
I spent weeks asking how to get people to keep a list. The answer was a phone number already typed at a pharmacy counter. Building on a habit that exists beat inventing a new one.
from the ideation
02
Ask, do not guess.
Every confirm card exists because one silent wrong guess about a medicine costs more trust than any number of extra taps.
from the review screen
03
Every action needs a visible result.
Got it worked, and people still thought it had failed, because nothing changed on screen. Now it opens the summary.
from testing, task 03
04
Do not hand the app’s job to the person.
Asking people to sort a paper before photographing it was the slowest step in testing. Sorting is the app’s work.
from testing, task 01
05
Tone is a design decision.
The duplicate asks for a choice, so it can carry weight. The interaction note asks nothing, so it must carry none.
from task 03
06
Put the holes on the page.
I could not confirm that a vendor would agree, or that ABDM can carry a dispense. Saying so myself is stronger than being caught.
from the research
07
Design for the role, not the age.
“Myself” in the relationship list means the patient can be the one managing. The job matters, not the demographic.
from setup
08
Small research, said out loud.
Six conversations and eleven testers were enough to find problems, not to prove the design is right. The next round is where that gets earned.

WHAT COMES NEXT
Six things are still open.
Leaving them visible is more useful than a neat ending.
Talk to a billing vendor.
The automatic route depends on one of them agreeing to send a sale. Nothing in the design removes that assumption.
Confirm ABDM can carry a dispense.
Pharmacies are a registered facility type. Whether a dispensed medicine can be pushed like a lab report, I could not confirm.
Make food timing a required choice.
Before food or after food, so no medicine can be added without it.
Test the daily list against a single list.
Morning, afternoon or night answers today’s question. It also costs a tap before anything is shown.
Rename the Activity groups.
“Noted for your doctor” says where an item is going, not what it is.
Test with someone managing from another city.
The person away from home is the one with the least to go on. They were not in this round.
