Case 1
PrairiePatch Health: when a successful pilot starts stressing the system
Case narrative
PrairiePatch Health began as a simple idea: help home care nurses track wound healing between visits. The first prototype used a disposable colour calibration sticker, a phone camera workflow, and a clinician dashboard. In the pilot, nurses took standardized wound photos, the app prompted for measurements and patient-reported symptoms, and the dashboard helped a wound-care specialist review changes remotely.
The initial Alberta pilot involved 80 patients across two care teams. It worked well enough to attract interest from additional primary care networks and a rural health innovation program. Maya's team now has a letter of intent for a 1,200-patient expansion. The opportunity is real, but the technical model is fragile. Photos are large, uploads fail in weak connectivity zones, the disposable sticker supply chain is manual, and the dashboard slows down when specialists review many cases at once.
The hardware element also creates scaling pressure. The stickers are inexpensive in small batches, but quality varies between suppliers. A batch with slightly different colour response could affect measurement consistency. The software team wants to automate image quality checks, but the regulatory advisor warns that the more the system influences clinical interpretation, the more disciplined the evidence and change-control story must become.
Dilemma
Maya must decide whether to accept the 1,200-patient expansion immediately or pause to rebuild the hardware supply process, image pipeline, cloud storage model, and support workflow. If she slows down, she risks losing momentum. If she scales too quickly, she may create clinical, privacy, operating cost, and reliability problems that damage trust.
Options
- Accept the expansion now: add cloud capacity, hire temporary support, and manage hardware manually while learning from higher volume.
- Run a constrained scale pilot: expand to 300 patients first, with explicit uptime, upload success, sticker quality, support, and clinical review metrics.
- Rebuild before scaling: qualify suppliers, redesign image compression and offline upload, add monitoring, and document verification before new sites launch.
- Split product claims: keep the near-term product positioned as workflow and documentation support while deferring stronger measurement claims.
Discussion
- What technical metrics should Maya require before moving from 80 to 1,200 patients?
- Where does hardware quality become a software, clinical, or regulatory issue?
- How should the team model image storage, bandwidth, review workload, support tickets, and sticker replacement cost?
- What Alberta privacy and operational assumptions need to be documented before the larger pilot?
- Which claims can PrairiePatch make safely now, and which should wait for stronger evidence?
