Operational Evidence, Not Just Platform Claims
Delve’s model is built around a simple premise: in long-duration studies, visibility is not enough. Sponsors need a layer that can identify drift early, intervene quickly, reduce site burden, and restore continuity before missingness becomes permanent.
- High ePRO completion is supported through follow-up workflows, not just scheduled reminders
- Wearable compliance is sustained by pairing digital monitoring with live patient support
- Retention improves when support, escalation, and recovery are treated as active study operations
- Issue resolution accelerates when one team owns the follow-through instead of distributing accountability across multiple parties
This is the difference between collecting data and protecting the conditions required for that data to remain usable over time.
Who This Page Is For
This page is built for sponsors and teams running post-market programs where long-term compliance is part of endpoint usability, not just an operational afterthought.
- MedTech PMCF programs requiring sustained patient engagement
- Post-approval studies with years of follow-up
- Real-world follow-up models where visits become less frequent over time
- Studies using wearables in clinical trials that need continuity beyond device deployment
- Programs where sites need added support through site enablement for long-duration studies
Operational Failure Modes in Post-Market Studies
Post-market studies do not usually fail from a single event. They degrade through repeatable operational failure modes that accumulate between visits and weaken endpoint usability over time.
- 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 all see part of the problem, but no single layer owns recovery end-to-end
- Delayed escalation: issues are visible in dashboards but are not acted on quickly enough to prevent compounding data loss
- Normalized missingness: repeated lapses stop feeling exceptional and begin to be treated as expected study noise
These are not abstract risks. They are the recurring operational patterns that reduce the interpretability of long-term post-market, PMCF, and post-approval datasets.
Regulatory Reality: Post-Market Evidence Still Depends on Execution
Post-market studies are not simply commercial follow-up programs. They 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 generation after approval when ongoing safety or effectiveness questions remain
- Device post-approval studies are used to help assure continued safety and effectiveness after market entry
- PMCF programs under European device frameworks rely on structured post-market clinical follow-up, not passive observation
- Real-world follow-up becomes more important as evidence expectations extend beyond the controlled site visit model
In practice, regulatory intent does not guarantee operational execution. If patients disengage, wearable continuity weakens, or site follow-up becomes inconsistent, the evidence plan can remain formally intact while the dataset itself quietly loses strength.
That is why post-market execution must be treated as an operating discipline, not just a documentation requirement.
PMCF, Post-Approval Studies, Real-World Follow-Up, and Wearables in Post-Market Studies
PMCF and post-approval studies are not just evidence-generation exercises. They are operational models that depend on sustained follow-up, patient responsiveness, data continuity, and recovery when adherence begins to slip.
- 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 create sync failure, charging fatigue, and support burden
That is why the strongest programs pair digital infrastructure with a real operating layer and patient concierge services that can intervene when passive tools are not enough.
The Four Pillars of Long-Term Post-Market Execution
The strongest post-market studies combine digital data capture with an active operating layer that identifies drift, intervenes quickly, reduces site burden, and protects endpoint continuity over time.
eCOA That Supports Long-Term Adherence
Structured patient reporting that helps sponsors see where long-term follow-up begins to weaken.
Wearable Continuity Monitoring
Track sync failure, charging fatigue, and declining usage before data loss becomes normalized.
Human Recovery of Patient Drift
Live support helps restore adherence, resolve friction, and reduce the burden placed on sites.
Real-Time Visibility Across Follow-Up
See unresolved issues across eCOA, wearables, and support signals before they erode long-term data quality.
What Sponsors Should Do Differently
Long-term compliance should not be treated as a downstream KPI. It should be designed as an operating model with clear ownership, intervention logic, and visibility across every patient-facing touchpoint.
- Design multi-year follow-up with recovery steps built in from the start
- Treat missed activity as recoverable rather than simply reportable
- Reduce the amount of support burden placed on sites alone
- Connect eCOA, wearables, analytics, and human support under one operating model
- Use site enablement for long-duration studies where site teams need structural support
- Close the loop on patient friction before missingness becomes accepted loss
Why Delve Health Fits Post-Market Programs
Delve Health is built for studies where execution quality determines whether long-term evidence remains interpretable. Our role is not limited to digitizing collection. We help sponsors operate the continuity layer that sits between visits, across patient reporting, wearables, support workflows, and escalation management.
- Execution continuity: detect drift before it becomes normalized missingness
- Human recovery: use live support when automation is no longer enough
- Site burden reduction: support sites without expecting them to own every recovery workflow alone
- Unified visibility: connect eCOA, wearable, and patient support signals under one operating layer
- Long-duration fit: support PMCF, post-approval, and real-world follow-up models where continuity matters more each month
This makes Delve particularly relevant when study success depends not just on enrollment or endpoint design, but on the sponsor’s ability to sustain follow-up discipline over years.

Frequently Asked Questions
Why do post-market studies struggle over time?
Because long-duration programs create repeated opportunities for adherence decay, wearable continuity loss, site burden transfer, and delayed escalation between visits.
What is PMCF and why does execution matter?
PMCF depends on sustained patient engagement, ongoing clinical evidence collection, and reliable long-term follow-up. Passive tools alone do not restore adherence once patients begin to drift.
Are wearables enough for post-market studies?
No. Wearables can provide valuable signal, but they do not by themselves recover missed syncs, charging fatigue, non-wear, or patient disengagement. Those failure modes require operational follow-through.
Why are sites alone often not enough for long-term follow-up?
Sites remain central to study execution, but many are not 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 combines eCOA, wearables, analytics, and human-led patient support to detect issues early, recover continuity, reduce site burden, and help sponsors preserve usable long-term datasets.
