Medical devices, digital health and remote monitoring — OSCE
OSCE communication-and-shared-decision station in which the candidate counsels a family on the validity, equity pitfalls and deployment of three digital-health devices: a parent's smartwatch rhythm flag, a continuous glucose monitor with night-time alarms, and a home pulse oximeter for a dark-skinned infant with bronchopulmonary dysplasia.

Prompt
You have 9 minutes with the parents of an eight-year-old whose smartwatch has flagged an irregular rhythm, whose four-year-old sibling with type 1 diabetes is having night-time CGM alarms the family wish to stop, and whose six-month-old sibling with bronchopulmonary dysplasia is on home pulse oximetry. Counsel the family on the validity of each device, the equity pitfalls, and the shared decision to continue, modify or stop.
Station brief (candidate)
- Counsel the family on the validity of the smartwatch rhythm flag as a screening signal rather than a diagnosis, and outline the device-independent confirmatory pathway (the 12-lead ECG and clinician overread). [9]
- Counsel the family on the CGM physiology and the plasma-interstitial lag, review the ISPAD 2024 ambulatory glucose profile targets, and reach a shared decision to tune the thresholds rather than abandon the device. [4]
- Counsel the family on the demonstrated inaccuracy of pulse oximetry in dark skin pigmentation and low perfusion, and agree a written action plan that names the equity limitation and the threshold to escalate to the emergency department. [5] [6] [7]
