A health system says that remote monitoring lowers hospital readmissions because patients who enrolled were readmitted less often than patients who declined. Which evidence would most strengthen the conclusion by reducing self-selection?
A
Enrolled patients have fewer readmissions than decliners, but enrollment reflects motivation and technology comfort.
B
Eligible patients are randomly offered immediate or delayed access, and administrative outcomes follow original assignment.
C
A rich matched observational study controls recorded illness and demographics but cannot remove unmeasured selection.
D
Patients are randomly offered monitoring, but analysis includes only those who actively use the device.
E
Readmissions fall after launch, when the hospital also changes discharge planning and follow-up procedures.
