Post-market studies & PMCF
Post-market follow-up that holds for years.
Post-market studies rarely fail at enrollment. They degrade when support between visits isn’t actively owned. Delve owns long-term follow-up compliance across PMCF, post-approval, and real-world studies, keeping retention, wearable continuity, and eCOA adherence on track.
Why post-market studies drift.
They rarely fail from a single event. Over a 3–5 year horizon, small lapses between visits add up and weaken the dataset.
- Diary and questionnaire completion decline gradually, not all at once
- Charging fatigue, non-wear, and sync failures erode wearable signal
- Longer gaps between visits leave room for silent disengagement
- Sites are left to recover follow-up without dedicated support
- Everyone sees part of the problem, but no one owns recovery
How Delve keeps follow-up on track.
Digital data capture plus an active operating layer that spots drift, steps in quickly, and protects continuity for years.
eCOA for long-term adherence
Structured patient reporting that shows where long-term follow-up begins to weaken.
Explore eCOA → 02Wearable continuity monitoring
Sync failure, charging fatigue, and declining use tracked before data loss becomes normal.
Explore wearables → 03Human recovery of patient drift
Live support restores adherence, resolves friction, and takes burden off sites.

Unresolved issues across eCOA, wearables, and support, seen before they erode data quality.

Long-term compliance isn’t a downstream KPI. Design it as an operating model with clear ownership, intervention logic, and visibility at every patient touchpoint.
- Build recovery steps into multi-year follow-up from the start
- Treat missed activity as recoverable, not just reportable
- Connect eCOA, wearables, analytics, and human support in one model
- Take support burden off sites with site enablement for long-duration studies
- Close the loop on patient friction before missingness becomes accepted loss
Operational evidence, not just platform claims.
In long studies, visibility isn’t enough. Someone has to spot drift, step in, and restore continuity before missingness becomes permanent.
- High ePRO completion comes from follow-up workflows, not just scheduled reminders
- Wearable compliance holds when monitoring is paired with live patient support
- Retention improves when support and recovery are run as active study operations
- Issues resolve 60% faster when one team owns the follow-through

Failure modes, regulatory context, and study types, for teams planning long-term follow-up.
Who this is for
Sponsors and teams running post-market programs where long-term compliance is part of endpoint usability, not an operational afterthought.
MedTech PMCF programs
Programs that require sustained patient engagement.
Post-approval studies
Studies with years of follow-up.
Real-world follow-up
Models where visits become less frequent over time.
Wearable-enabled studies
Studies using wearables in clinical trials that need continuity beyond device deployment.
Stretched sites
Programs where sites need added support through site enablement for long-duration studies.
Seven operational failure modes
These are the recurring patterns that reduce the interpretability of long-term post-market, PMCF, and post-approval datasets.
Adherence decay
Diary completion, questionnaire response, and task participation decline gradually rather than collapsing all at once.
Wearable continuity loss
Charging fatigue, non-wear, sync failure, and device friction reduce usable signal over time.
Follow-up spacing risk
Longer intervals between in-person visits create larger windows for silent disengagement.
Site burden transfer
Sites are expected to recover missed follow-up, troubleshoot devices, and re-engage patients without dedicated infrastructure.
Fragmented accountability
Sponsor, site, patient, and vendor each see part of the problem, but no single layer owns recovery end to end.
Delayed escalation
Issues are visible in dashboards but aren’t acted on fast enough to prevent compounding data loss.
Normalized missingness
Repeated lapses stop feeling exceptional and start being treated as expected study noise.
Regulatory reality: post-market evidence still depends on execution
Post-market studies often sit inside regulatory, safety, lifecycle, and evidence-generation obligations that require sponsors to maintain data continuity after approval.
FDA postmarketing requirements and commitments
Can require additional evidence after approval when safety or effectiveness questions remain.
Device post-approval studies
Help assure continued safety and effectiveness after market entry.
PMCF programs
European device frameworks rely on structured post-market clinical follow-up, not passive observation.
Real-world follow-up
Matters more as evidence expectations extend beyond the controlled site visit model.
Regulatory intent doesn’t guarantee execution. If patients disengage, wearable continuity weakens, or site follow-up slips, the evidence plan can stay formally intact while the dataset quietly loses strength. Post-market execution has to be run as an operating discipline, not just a documentation requirement.
PMCF, post-approval studies, real-world follow-up, and wearables
These are operational models, not just evidence-generation exercises. Each depends on sustained follow-up, patient responsiveness, data continuity, and recovery when adherence slips.
PMCF
Requires reliable long-term follow-up and documented recovery of engagement.
Post-approval studies
Often run long enough for operational drift to become the main threat.
Real-world follow-up
Reduces control and increases the need for execution discipline.
Wearables in post-market studies
Add signal value, but also bring sync failure, charging fatigue, and support burden.
The strongest programs pair digital infrastructure with a real operating layer and patient concierge services that step in when passive tools aren’t enough.
Why Delve fits post-market programs
Delve’s role isn’t limited to digitizing collection. We help sponsors run the continuity layer between visits, across patient reporting, wearables, support workflows, and escalation.
Execution continuity
Detect drift before it becomes normalized missingness.
Human recovery
Live support when automation is no longer enough.
Site burden reduction
Support for sites, without expecting them to own every recovery workflow alone.
Unified visibility
eCOA, wearable, and patient support signals under one operating layer.
Long-duration fit
PMCF, post-approval, and real-world follow-up models where continuity matters more each month.
That matters most when success depends not just on enrollment or endpoint design, but on sustaining follow-up discipline over years.
Questions sponsors ask about post-market studies.
Why do post-market studies struggle over time?
Post-market studies often degrade because long-term compliance, patient support, wearable continuity, and follow-up recovery aren’t actively owned as a continuous operating layer. Long programs create repeated chances for adherence decay, continuity loss, site burden transfer, and delayed escalation between visits.
What operational failure modes reduce post-market study quality?
Common failure modes include adherence decay, wearable continuity loss, follow-up spacing risk, site burden transfer, fragmented accountability, delayed escalation, and normalized missingness.
What is PMCF and why does execution matter?
PMCF, or post-market clinical follow-up, depends on sustained patient engagement, data continuity, and reliable long-term follow-up. Execution matters because passive monitoring alone doesn’t restore adherence once drift begins.
Are wearables enough for post-market studies?
Wearables add valuable signal, but they don’t by themselves recover missed syncs, charging fatigue, non-wear, disengagement, or site follow-up gaps. Those issues require an operating layer.
Why are sites alone often not enough for long-term follow-up?
Sites remain central to study execution, but many aren’t structured to own every patient support, troubleshooting, and recovery workflow required in long-duration post-market studies.
How does Delve Health support post-market studies?
Delve Health combines eCOA, wearables, analytics, and human concierge support to detect drift early, recover adherence, reduce site burden, and help sponsors protect long-term data continuity.
