Designing a patient-facing medication adherence app for elderly users with chronic conditions
CareSync is a care coordination platform operating in the same space as this concept. A mixed-method research approach — augmented by Gen AI synthesis — surfaced what a genuinely patient-first medication adherence app for elderly users needs to be.
Research on medication adherence in chronic-condition adults 65+ found rates as low as 34% — far below clinical thresholds. Stakeholders blamed notification fatigue. Research revealed something more structural: no one had designed for the caregiver in the room.
A mixed-methods research sprint combining contextual inquiry, diary studies, and clinical interviews — augmented by Gen AI synthesis — identified the root causes and drove a complete redesign of the patient-caregiver interaction model.
58% of participants had a family caregiver helping manage their medications — but the app had no shared access model. 71% of missed doses came not from forgetfulness, but from routine disruption. And 4 of 8 diary participants reported anxiety triggered by the app's own alarming "MISSED" states.
The redesign addresses each of these: caregiver-linked accounts, routine-anchored flexible windows, and a complete language and colour overhaul toward calm, human tone.

Each projected figure is grounded in a specific data source from the research and testing process — not extrapolated from thin air. Here's the chain of evidence behind each metric.
Baseline established from literature: The 38-paper AI synthesis placed chronic condition adherence in adults 65+ at approximately 34% for rigid clock-based reminder apps — consistent with the WHO's reported 50% average non-adherence in chronic illness.
Testing showed a marked reduction in simulated missed doses: In prototype test tasks, participants using flexible time windows completed significantly more dose-logging tasks successfully than in the rigid-schedule comparison tasks — directly mirroring the research finding that 71% of real missed doses were disruption-related, not forgetfulness-related.
Comparable published research: Studies on mHealth adherence interventions that introduce caregiver coordination features and flexible scheduling windows have reported adherence gains in the 25–40% range in elderly chronic condition cohorts. The 31% projection sits conservatively within that published range — not at its upper bound.
SUS scores tracked across test rounds: System Usability Scale scores were collected after each of the 3 testing rounds (n=18 across all rounds). Scores increased meaningfully from mid-fi to hi-fi, moving from the "marginal" band into the "good" range — consistent with the removal of anxiety-producing states and the simplification of the dose-logging flow. The abandonment projection is modelled from this SUS trajectory, not from a direct retention measurement.
Anxiety-driven drop-off directly addressed: 4 of 8 diary participants explicitly reported app-triggered anxiety from the "MISSED" state. Post-redesign, none of the hi-fi test participants flagged equivalent anxiety in debriefs. Removing a documented primary stressor is a strong signal toward reduced abandonment in this cohort, though the 47% figure itself is a conservative modelled estimate — not a measured dropout rate.
Task error rates in prototype testing: In structured test tasks comparing the existing flow against the redesign, participants made significantly fewer dose-logging errors in the hi-fi prototype. Think-aloud transcripts showed the primary error driver — confusion between "MISSED" state and a genuinely skipped dose — was eliminated entirely in the redesign, accounting for the majority of the projected reduction.
Caregiver proxy coverage: 58% of participants had an invisible caregiver managing doses. The new shared-access model means a second person can confirm, log, or flag missed doses — adding a redundancy layer that error modelling suggests could reduce net missed doses by an additional 18–22% on top of direct UI improvements.
Post-test satisfaction ratings: A single-item satisfaction question ("How would you rate this experience overall?") was asked after each hi-fi prototype session. Responses clustered strongly in the 4–5 range across all 18 sessions, with the mean landing at 4.7. This is a post-session usability rating, not an App Store simulation — it reflects how participants felt after completing tasks with the prototype under test conditions.
Caregiver participants scored highest: The 6 nurse expert interviews and 4 caregiver-proxy participants gave the highest satisfaction marks specifically for the shared-access and flexible-window features — the two decisions most directly driven by the AI transcript analysis.
These projections represent the designer's best-evidence estimates based on primary research, prototype testing data, and published benchmarks in comparable mHealth contexts. They are not measured outcomes. Validation would require a live deployment with longitudinal tracking.
Manual literature synthesis across 38 papers would have taken two weeks. The AI synthesis took two hours — and surfaced the caregiver proxy pattern that wasn't even in the original brief. That reframe drove the entire redesign direction.
Transcript analysis surfaced 14 emotional themes — including shame around asking for help — that would have been easy to overlook in manual coding. AI didn't interpret them. But it made sure I didn't miss them.
