Why Andrew Ting, MD, Champions AI To Keep Your Medication List Clean And Accurate Across Health Apps

Medication lists are deceptively fragile. What appears as a simple record of prescriptions is often the product of fragmented systems, delayed updates, patient memory gaps, and inconsistent data standards across health apps and care settings. Andrew Ting, MD, has repeatedly emphasized that the most dangerous medication errors rarely come from dramatic mistakes, but from small discrepancies that quietly persist across platforms and encounters.

Why Medication Lists Drift Out of Sync

Hospital EHRs, primary care portals, pharmacy applications, wearable-connected platforms, and insurance medication histories are just a few of the digital touchpoints that modern patients deal with. Although a “current” drug list may be stored in each system, none of them can be considered authoritative.

Drift happens for predictable causes. After being released from the hospital, prescriptions are modified, but they are never deleted from outpatient records. Without knowing what another practitioner recently stopped prescribing, a specialist adds a drug. Patient-managed applications get over-the-counter medications and supplements, but they never make it to clinical systems. Two versions of the same drug may be active at the same time if even dose adjustments are delayed.

The Clinical Risk of Dirty Medication Data

Three different error categories are commonly produced by medication reconciliation failures: hazardous interaction, omission, and duplication. When therapeutically comparable medications are distributed under various brand or generic names across disparate systems, it’s known as duplicate therapy. This keeps overlapping anticoagulants or antihypertensives active at the same time.

During care transitions, omission errors occur when long-term drugs are forgotten, disrupting the management of chronic illnesses that do not have acute clinical visibility. When new prescriptions are compared to incomplete medication lists, interaction risks arise, and decision-support tools may overlook contraindications or compound side effects.

Why Manual Reconciliation Falls Short

Episodic review is the foundation of traditional medication reconciliation. When a patient is asked what they are taking, a physician checks their answer to a list that already exists and instantly resolves any differences. This method is predicated on a static drug environment, adequate appointment time, and accurate patient memory. None of those presumptions is always true.

Physicians frequently deal with lengthy lists of past prescriptions that are therapeutically useless yet technically “active” in the system. It becomes cognitively costly to separate signal from noise, which promotes heuristics rather than accuracy. Reconciliation eventually stops being a remedial procedure and instead becomes a checkbox.

How AI-Assisted Medication Reconciliation Works in Practice

Instead of seeing medication reconciliation as a one-time task, AI systems view it as an ongoing data quality issue. EHRs, pharmacy claims, patient-entered information, and third-party health applications are just a few of the sources from which they consume pharmaceutical data. They examine patterns of overlap, time, dosage, and pharmacologic class rather than presuming equivalency.

The system signals a discrepancy for physician review when it finds a possible duplicate, such as two medications with the same therapeutic aim but overlapping administration windows. The AI identifies the omission and tracks its source when a drug vanishes from one system but is still active in another. The most complete version of the drug list is used to assess interaction risks, not whatever subset is displayed in a particular interface.

Keeping Medication Lists Aligned Across Health Apps

The issue of cross-platform consistency is one of the most overlooked problems in contemporary healthcare. More and more patients are using consumer-facing apps to manage their health, which might not work well with clinical systems. By mapping similar drugs across naming conventions, formats, and update cadences, artificial intelligence (AI) reconciliation technologies serve as middlemen.

The technology can determine whether a medicine change is consistent with recent prescriptions or goes against established treatment regimens when a patient enters it in a personal health app. If there is a disparity, it is discovered prior to the subsequent clinical visit instead of being undetected for several months.

Operational Benefits Beyond Safety

Patient safety is not the only benefit of clean drug listings. They increase the precision of clinical decision support systems, expedite previous authorizations, and decrease pharmacy callbacks. When the underlying pharmaceutical data is trustworthy, order sets perform better. When drug exposure is accurately represented, risk models produce projections that are more accurate.

From an operational standpoint, staff time spent fixing downstream problems is reduced when there are fewer medication-related clarifications. AI-assisted reconciliation moves work upstream, where adjustments are less expensive and cause less disturbance.

Why This Focus Matters Now

Without proactive intervention, prescription data will only become more fragmented as treatment becomes increasingly digital and distributed. An abundance of incompletely reconciled information, rather than a lack of information, is the issue. Dr. Andrew Ting has maintained that considering medication reconciliation as infrastructure rather than documentation is necessary to solve this issue.

Because AI operates continually, across systems, and at a scale that no human team can match, it makes that transformation possible. The objective is a significant decrease in the silent mistakes that gradually undermine safety, not perfection.

Final Thoughts

Medication reconciliation is one of the least visible yet most consequential processes in healthcare. By championing AI-assisted approaches, Andrew Ting, MD, highlights a practical path toward cleaner, more accurate medication lists that persist across health apps and care settings. When duplicates, omissions, and interaction risks are surfaced early and consistently, clinicians regain trust in the data they rely on, and patients benefit from safer, more coordinated care.
