Treatment only works
if it continues.

Digital support more than doubles the odds it does. We verify that it did, dose by dose, from day 1 of initiation.

A link on any phone. No app, no hardware, no field agents.

  • Behavior stalls surfaced monthly
  • Patient-reported side effects, structured
  • Visit readiness signal
  • Verified device return rate
Why Early Support Pays

Digital support doubles the odds.
Nobody verified it.

9 randomised trials, more than twice the odds of adherence. Every one of them measured it by asking the patient.

Armitage, Kassavou & Sutton, BMJ Open 2020;10(1):e032045. Read the study

A patient who stops at month 3 of a 12-month therapy takes 9 months of treatment revenue with them, on top of the acquisition spend already made. The support that keeps them has published evidence behind it. What no sponsor can show today is whether it worked in their own cohort. Play4Health supplies that half: photo-confirmed, timestamped, from day 1 of initiation.

Trial populations covered cardiovascular disease, depression, Parkinson's disease, psoriasis and multimorbidity, at moderate evidence quality. Not a forecast for any specific programme, and not a Play4Health result.

The part no one else covers

Adherence platforms stop at the dose.
We close the loop.

Every tool tracks whether the medicine was taken. None track what happens to the device afterwards.

Same patient, same action

Confirmed in the tool the patient already uses for doses. No parallel programme to fund.

Verified, not declared

Photo, timestamp and duplicate controls on every return. A counted number.

Feeds the same score

Returns count alongside dose confirmation. One dataset, not two reports.

We generate the verified return record. Collection and reprocessing stay with your logistics and waste partners.

What You Buy

Your programme. Live.

Dose confirmations, behavior stages, device returns and side-effect signals, across all cohorts.

How It Works

One photo.
Four verified outcomes.

Patients participate directly. No app, no hardware, no clinic visit.

01

Patient takes a photo

Dose or device return confirmed from a link. No login friction.

02

Verification runs automatically

Timeframe rules, duplicate controls and photo context checked instantly.

03

Behavioral reinforcement

Streaks and progress signals sustain daily engagement. No cash incentive tied to any prescription decision.

04

Data flows to your dashboard

Live and export-ready for PSP and medical affairs reporting.

The score behind the metrics

Adherence is not one number.
The HAI scores the behavior behind it.

A percentage tells you doses were missed. The Health Adherence Index tells you who has stopped engaging with the routine, while they are still reachable.

A behavioral signal for programme management. Not a diagnostic tool, and no replacement for clinical judgment.

What the index combines

Where It Applies

Built for treatments
taken every day.

Any regimen where a missed dose stays invisible until the next appointment. The four we start with.

Asthma

Taken daily by patients who feel fine. Silent drop-off, discovered at the exacerbation.

Inhaler return loop

COPD

Multiple inhalers, older patients, complex technique. Hospitalisations track to interrupted therapy.

Inhaler return loop

Diabetes

Injection pens, titration and side-effect burden. Discontinuation surfaces months after control is lost.

Pen return loop

Drug-resistant TB

Long regimens, heavy side effects, resistance as the cost of interruption. Adherence is the outcome.

Adherence only, no device stream

We enter at initiation, because that is where a routine can still be shaped, and we stay for as long as the treatment lasts. Condition-agnostic: all it needs is a near-daily action a patient can confirm, and where a device is involved the return loop runs on the same action. The economics are sharpest on high-cost therapy, where a patient lost early is an immediate loss against an acquisition cost already spent.

Where we stand

Play4Health is pre-commercial. We are selecting the first sponsor programmes now.

  • No patient cohort deployed yet. Nothing on this page is a Play4Health result.
  • 20,000+ early field actions captured on the Play for Earth verification engine, the same layer Play4Health runs on.
  • No new hardware or headcount required to deploy.
Pricing

Priced against what a lost cohort costs.

Compare the pilot to the revenue you lose when one patient stops early. On high-cost therapy, the comparison is short.

Every contract includes the full system. Only scope changes. Device recovery volumes are reported in both tiers; collection and reprocessing are scoped separately, on their own budget line.

Our North Star

Healthcare without waste.
Better outcomes for patients.
Better outcomes for the planet.

We start with adherence and device returns, because that is where outcomes are real and regulatory pressure is building today.
