The Internet of Medical Things is generating extraordinary clinical data. Connected CPAP machines report nightly usage, mask leak rates, and apnea events in real time. Smart scales transmit daily weights to heart failure care teams. CGMs deliver continuous glucose readings that transform diabetes management. Infusion pumps track medication delivery accuracy minute by minute. The data infrastructure is remarkable.
The adherence infrastructure is not keeping pace.
A CPAP machine that generates perfect compliance data for a patient who uses it every night is clinically valuable. The same machine sitting on a nightstand because the mask was uncomfortable and nobody called to help the patient troubleshoot is generating no clinical value — while appearing in the provider’s billing system as an active dispensed device. IoMT adherence is the gap between device deployment and clinical outcome. And the factor that most consistently predicts whether a patient closes that gap — or doesn’t — is not device technology. It’s the quality of human support around the device.
This article covers the IoMT adherence challenge in DME, why empathy is the underappreciated clinical variable, what the evidence shows about support program design, and how DME providers build patient support programs that actually improve adherence at scale.
The IoMT Adherence Problem — Quantifying the Gap
Across DME categories, adherence rates consistently fall below the clinical threshold required for meaningful outcome improvement. The gap between device deployment and consistent use is not a niche problem — it is the central operational challenge of connected medical device programs.
| Device Category | Clinical Adherence Threshold | Typical Adherence Without Active Support | With Structured Support Program |
|---|---|---|---|
| CPAP / BPAP | ≥4 hours/night on ≥70% of nights (CMS standard) | 40–55% meet threshold at 90 days | 65–78% meet threshold at 90 days |
| CGM (continuous glucose monitor) | ≥70% sensor wear time | 58–65% at 6 months | 75–85% at 6 months |
| Home oxygen concentrator | Prescribed usage hours per day | 50–65% meeting prescribed hours | 70–80% with adherence coaching |
| RPM weight scale (heart failure) | Daily transmission (≥16 days/month for CMS billing) | 55–65% meeting threshold at 90 days | 76–85% with proactive engagement |
| Wearable cardiac monitor | Continuous wear as prescribed | 60–70% adequate wear at 30 days | 80–90% with setup support and follow-up |
The column on the right — adherence rates with structured support programs — is not aspirational. It reflects documented outcomes from programs that systematically invest in patient support alongside device deployment. The adherence gap between the third and fourth columns reflects the clinical outcomes achieved by empathetic, proactive support. It also represents, in many cases, the difference between a billable device and an unbillable one — since CMS DME reimbursement in several categories is conditional on demonstrated compliance.
Why DME Patients Don’t Adhere — The Actual Reasons
Understanding DME non-adherence requires setting aside the assumption that patients who don’t use their devices are simply unmotivated. Research on medical device adherence consistently shows that non-adherence clusters around specific, addressable barriers — not around patient character.
Physical Discomfort
CPAP mask discomfort is the single most frequently cited reason for CPAP non-adherence. A patient who wakes up every night with mask leak, pressure marks, or dry mouth has a rational reason to stop using the device. That reason is almost always fixable — mask sizing, humidifier adjustment, pressure setting modification — but only if a support agent asks about it. Patients who never receive a follow-up contact don’t report mask issues. They simply stop using the device.
Physical discomfort is similarly relevant for CGM sensor placement, wearable cardiac monitor lead adhesion, compression garment fit, and mobility aid ergonomics. Every device that touches the patient’s body generates comfort-related adherence barriers. Every one of those barriers is addressable with a timely support conversation.
Technical Difficulty
IoMT devices require patients to maintain connectivity — Bluetooth pairing, app synchronization, data transmission — that creates ongoing technical failure opportunities. A CGM that loses its phone connection doesn’t just stop generating data. It generates confusion and frustration that, without resolution, produces device abandonment. A heart failure patient whose scale stops transmitting may not know the transmission failed. They assume someone is still watching and stop worrying about whether the data is getting through.
Technical support for IoMT devices is a continuous need — not a one-time setup service. Devices that worked perfectly in week one may fail in week four after a smartphone OS update. Patients who don’t have access to timely technical support when these failures occur resolve them by stopping use.
Lack of Perceived Benefit
Devices that treat asymptomatic conditions — such as hypertension monitoring and overnight CPAP for obstructive sleep apnea that the patient doesn’t find disruptive — face a specific adherence challenge. The patient feels fine. The device feels intrusive. The benefit is abstract — “reduces your cardiovascular risk over the next five years” — while the discomfort is immediate.
Motivational support for this barrier category requires a different conversation than troubleshooting. It requires a support agent who can connect the abstract risk reduction to something personally meaningful — the patient’s grandchildren, their ability to maintain independence, their fear of a specific complication — in a way that makes the nightly device use feel worthwhile. This is empathy as a clinical intervention.
Anxiety and Fear
Some patients are afraid of what their device might reveal. A heart failure patient who knows their daily weight triggers a clinical alert when it increases may avoid weighing themselves — not out of indifference but because they don’t want to know that their condition is worsening. A cardiac monitor patient may feel anxiety every time the device records an irregularity.
This anxiety is clinically counterproductive. The patient most likely to benefit from early detection is avoiding the monitoring that would enable it. Addressing device-related health anxiety requires support agents trained to recognize it, normalize it, and reframe it — not dismiss it with reassurance, but genuinely engage with the patient’s fear in a way that makes continued monitoring feel like self-care rather than surveillance.
The Empathy Imperative
Every one of these non-adherence barriers responds to human engagement. A trained support agent who asks the right question at the right moment — “I noticed you haven’t been using your CPAP — can I ask what’s been getting in the way?” — and responds with genuine curiosity and problem-solving intent, converts non-adherence to adherence in a proportion of cases that no technical improvement can match.
Empathy as Clinical Intervention — What the Evidence Shows
The healthcare literature on patient adherence consistently identifies the therapeutic relationship as one of the strongest predictors of adherence behavior — across medication adherence, treatment adherence, and device adherence. Patients who feel that someone in their care system genuinely understands their experience, takes their concerns seriously, and is working with them rather than at them adhere at higher rates than patients who feel like compliance objects in a monitoring system.
“We analyzed our CPAP adherence data across three support models: no follow-up, automated reminder calls, and live agent follow-up calls. The live agent model produced 34 percentage points higher adherence at 90 days than no follow-up, and 22 points higher than automated reminders alone. The content of the automated reminders was almost identical to the live call script. The difference was the human presence — the patient’s ability to respond, ask questions, and feel heard.”
— VP Clinical Programs, Regional DME Provider
The mechanism behind this effect has been studied extensively in medication adherence research — where it is called the “therapeutic relationship effect” — and the findings translate directly to device adherence contexts. Patients adhere to recommendations made by providers and support staff they trust. Trust is built through consistent, empathetic, person-centered interactions. Not through compliance nagging.
This has an operational implication that most DME support programs don’t fully act on. Empathy is not an adjunct to technical support. It is the primary driver of the impact on the support conversation’s adherence. A technically perfect troubleshooting call that leaves the patient feeling like a problem to be solved rather than a person to be supported produces lower adherence outcomes than a technically imperfect call that leaves the patient feeling genuinely cared for.
The IoMT Adherence Support Model — What It Looks Like in Practice
An effective IoMT adherence-support program for DME patients comprises five operational components. Each addresses a specific failure point in the adherence journey.
1. Empathetic Onboarding — The First 72 Hours
Device setup support in the first 72 hours after delivery is the highest-leverage adherence intervention in the program. Patients who successfully set up and use their device in the first three days have significantly higher 90-day adherence rates than those who don’t. The onboarding call must accomplish three things simultaneously: resolve technical barriers, establish a supportive relationship, and set realistic expectations about the device experience.
Realistic expectations are particularly important for CPAP, CGM, and wearable cardiac monitors — devices that require an adjustment period. A patient who expects their CPAP to feel comfortable immediately and finds the first week uncomfortable is likely to conclude the device “doesn’t work for them.” A patient who was told in the onboarding call that the first week is typically the hardest, that discomfort is common, and that there are specific adjustments available — and who has a direct contact number if problems arise — has a framework for persistence rather than a confirmation of failure.
2. Week-One Adherence Check-In
The first week of device use is the highest-risk period for dropout. Discomfort is most acute. Technical problems are most likely. Motivation is most susceptible to the friction of a new habit. A proactive check-in call at days 5–7 — before the second week begins — catches the majority of early abandonment risks at a moment when they’re still easily addressable.
The week-one check-in is specifically not a compliance review call. It is a welfare call. The framing matters. “I’m calling to check in and see how your first week has been going — not to check on your numbers” produces a different conversation than “I’m calling because your data shows your usage has been below the threshold.” The first framing invites the patient to share their experience. The second makes them feel monitored and judged.
3. Data-Triggered Personalized Outreach
IoMT devices generate adherence data that, when used correctly, enables precision outreach. A CPAP patient whose usage dropped from 7 hours nightly to 3 hours nightly between weeks 2 and 3 has likely encountered a specific barrier — a cold that made nasal breathing uncomfortable, a life event that disrupted sleep routine, a mask issue that developed gradually. A support call triggered by that data pattern — and personalized to that pattern — is more likely to identify and address the specific barrier than a generic monthly check-in.
Data-triggered outreach requires integration between the device data platform and the patient support system — so that the agent placing the call has visibility into the patient’s specific usage pattern and can reference it specifically. “I noticed your usage has been lower this week than it was in your first two weeks — has something changed?” is a more empathetic and effective opening than “I’m calling because our system shows your compliance is below threshold.”
4. Barrier-Specific Resolution Authority
Support agents who identify adherence barriers but lack the authority or knowledge to resolve them during the same contact generate patient frustration that worsens the barrier. A patient who reports mask discomfort and is told a DME technician will call back in 3–5 days is living with the discomfort for 3–5 more days. That’s 3–5 more nights of poor sleep, reinforcing the association between CPAP use and discomfort.
Agents with barrier-specific resolution authority can order a mask replacement immediately, initiate a pressure adjustment request to the prescribing physician, or schedule a same-day or next-day in-person device assessment for comfort issues that can’t be resolved remotely. Resolution in the first contact — or within 24 hours — is the adherence-critical outcome. Every day of unresolved barriers is a day of adherence erosion.
5. Long-Term Engagement — 30/60/90-Day Cadence
Adherence is not a one-time achievement. It is a behavior that requires ongoing maintenance — particularly for devices that patients will use for months or years. Structured engagement check-ins at 30, 60, and 90 days acknowledge this reality and act on it.
These check-ins don’t need to be long. A 5-minute call that confirms the patient is using their device, addresses any outstanding questions, and reinforces the clinical purpose of their monitoring is sufficient to reset adherence motivation and catch emerging barriers before they lead to abandonment. Programs with structured 30/60/90-day check-ins retain significantly more patients at 6 months than those that rely on data-triggered outreach alone.
IoMT adherence doesn’t improve through better devices. It improves with better human support around those devices — empathetic, timely, personalized, and empowered to resolve barriers at first contact.

Training Support Agents for Empathetic DME Adherence Support
Empathy in patient support is a trained capability — not a personality trait that some agents have and others don’t. The behaviors that constitute empathetic patient support are teachable, observable, and measurable. And they are distinct from the technical support skills that most DME support agent training programs focus on.
Active Listening
Active listening in a DME adherence context means allowing the patient to finish describing their experience before troubleshooting begins. It means asking clarifying questions that demonstrate the agent is processing what the patient is saying — not waiting for the patient to stop talking so the troubleshooting script can begin. And it means reflecting back what the patient shared in a way that confirms the agent understood correctly before moving to solutions.
The difference between an active listening response and a scripted troubleshooting response is immediately perceptible to patients. “That sounds really frustrating — let me make sure I understand what’s been happening” produces a different conversation outcome than “I see. Let’s try adjusting your mask fit.”
Non-Judgmental Framing
Patients who have not been using their device consistently often expect judgment when they receive a follow-up call. They’ve been “caught” not complying. Agents who approach non-adherent patients with genuine curiosity rather than implied judgment create conversations that produce honest disclosure of barriers, which is the information needed to address them.
“I noticed you haven’t been using your CPAP this week — is everything okay?” opens the conversation to the patient’s actual experience. “I’m calling because your usage is below the required threshold,” opens the conversation to defensiveness and incomplete disclosure.
Condition-Specific Knowledge
Empathy requires a clinical context. An agent who understands what obstructive sleep apnea feels like to a patient — the disrupted sleep, the daytime fatigue, the cognitive fog — can engage with the CPAP adherence conversation at a level of personal relevance that an agent who knows only the technical parameters cannot. Condition-specific training isn’t just clinical knowledge. It’s the foundation of genuine patient empathy.
This connects to the broader human support for wearable health technology framework — the same empathy-based support principles that drive adherence for wearable monitors apply across the full connected DME landscape.
Motivational Communication Techniques
Motivational interviewing — a structured approach to supporting behavior change by eliciting the patient’s own motivation rather than imposing external pressure — has strong evidence supporting its use in medication adherence, substance use treatment, and chronic disease management. Its principles translate directly to DME adherence support.
Agents trained in motivational communication techniques don’t tell patients why they should use their device. They ask patients what matters to them, what they hope to achieve, and what concerns they have about their device — and help them connect their device use to their goals. A patient who articulates for themselves why CPAP matters to them — better sleep so they can be present with their grandchildren, reduced fatigue so they can continue working — is more adherent than a patient who was told the same thing by an agent.
Population-Specific Adherence Challenges in DME IoMT Programs
Elderly Patients
Elderly DME patients face a specific combination of adherence barriers. Digital literacy challenges make IoMT device connectivity maintenance difficult. Multiple comorbidities mean the device is competing with many other health management demands for attention. Hearing and vision impairments can make setup instructions and device feedback harder to process. And the social isolation that affects many elderly patients means their device use — or non-use — may go unnoticed by anyone in their immediate environment.
Support programs for elderly DME patients require more time per contact, simpler technical explanations, phone-primary contact approaches rather than app-based, and more frequent proactive check-ins. The investment per patient is higher. The adherence return on that investment is also higher — elderly patients who receive adequate support adhere at rates that justify the contact cost many times over through avoided hospitalizations and sustained device billing eligibility.
Patients With Chronic Comorbidity Burden
Patients managing multiple chronic conditions — the heart failure patient who also has diabetes, hypertension, and chronic kidney disease — carry a device adherence burden that goes well beyond a single connected DME item. They may be managing a heart failure monitoring scale, a CPAP, a CGM, and multiple medication regimens simultaneously. The cognitive and motivational load is significant.
Support programs for high-comorbidity patients should consolidate adherence check-ins where possible — a single call covering all active device programs rather than multiple separate contacts for each device — and prioritize by clinical risk. The patient managing five devices who is struggling to adhere to any of them needs a different conversation than a patient managing one device who has encountered a specific technical barrier.
Patients With Language Barriers
IoMT adherence support for limited-English-proficient patients requires native-language capability at every touchpoint. Device setup instructions in English that the patient can’t read don’t establish correct use. Troubleshooting calls delivered through an interpreter are slower, more fragmented, and less empathetically connected than native-language calls. And the motivational communication techniques that drive adherence depend on linguistic fluency — motivational interviewing conducted through an interpreter loses the conversational texture that makes it effective.
For DME providers serving significant LEP populations — particularly Spanish-speaking patients in markets with large Hispanic communities — native-language adherence support is not a service enhancement. It is the difference between a connected device program that improves health outcomes for the full enrolled population and one that improves outcomes only for the English-proficient subset. The multilingual healthcare support framework covers the operational and clinical case for native-language DME support in detail.
IoMT Adherence and DME Billing — The Financial Alignment
DME patient adherence is not only a clinical concern. For several connected device categories, adherence directly determines billing eligibility — creating a direct financial alignment between adherence support investment and revenue protection.
| Device Category | CMS Adherence Billing Requirement | Revenue Risk of Non-Adherence |
|---|---|---|
| CPAP / BPAP | Patient must meet adherence threshold (≥4h/night on ≥70% of nights) for continued rental billing beyond 3 months | Non-adherent patient = discontinued monthly rental payments for up to 10 months of coverage period |
| RPM devices (CPT 99454) | ≥16 days of transmission per 30-day billing period | Non-compliant month = no 99454 reimbursement (~$55–65 per patient month) |
| Home oxygen | Usage records may be requested post-payment; continued prescription required | Post-payment audit recovery risk if usage doesn’t match billed duration |
| Enteral nutrition equipment | Monthly attestation of continued use required | Billing without continued use documentation is fraudulent billing risk |
The CPAP adherence-billing connection is the most operationally significant. A patient who fails the 90-day adherence check generates no rental billing for months 4–13 of the coverage period. At a monthly rental rate of $120–180, a single non-adherent CPAP patient represents $1,200–1,800 in lost rental revenue over the coverage period. A 20-patient adherence program that converts just 5 patients from non-adherent to adherent at the 90-day check recovers $6,000–9,000 in rental revenue, many times the cost of the adherence support program that produced the conversion.
This financial alignment makes the ROI case for DME adherence support programs extremely straightforward for CPAP-heavy operations. The adherence support investment required to improve compliance by 15–20 percentage points at the 90-day mark costs a fraction of the rental revenue that would otherwise be lost.
Measuring DME Adherence Support Program Effectiveness
Table: KPIs for Measuring DME Adherence Support Programs
| Metric | What It Measures | Target |
|---|---|---|
| 90-day adherence rate | % of enrolled patients meeting clinical adherence threshold at 90 days | CPAP: >70%; RPM: >75%; CGM: >75% |
| Week-one contact rate | % of newly enrolled patients reached within 7 days of device delivery | >90% |
| Barrier identification rate | % of non-adherent contacts where barrier is identified and documented | >85% — undocumented non-adherence can’t be addressed |
| First-contact barrier resolution rate | % of identified barriers resolved in the first support contact | >60% for technical barriers; >40% for motivational |
| CPAP rental continuation rate | % of CPAP rentals continuing to month 4 (adherence-dependent billing) | >70% with active adherence support program |
| Patient satisfaction with support | CSAT on support quality and perceived care | >4.4/5.0 — empathetic programs consistently score above technical-only programs |
| Adherence rate by support contact cadence | Compare adherence rates for patients receiving different contact frequencies | Identifies optimal contact investment for each device category and patient population |
Track barrier identification rate and first-contact resolution rate together. A high barrier identification rate with a low first-contact resolution rate indicates agents are asking the right questions but lack the authority or knowledge to solve what they find. A low barrier identification rate indicates agents aren’t having conversations deep enough to surface the real barriers — they’re completing compliance checks rather than conducting genuine adherence support conversations.
