PVC-RAM-1 was a multicentre, parallel group, superiority, randomized controlled trial to determine the effect of virtual care with remote automated monitoring (RAM) technology, compared to standard care on the 30-day risk of acute-hospital care (i.e., a composite of hospital re-admission and emergency department or urgent-care centre visit), in adults who have undergone non-elective surgery.

Patients in the experimental group received a tablet computer and RAM technology, which measured blood pressure, heart rate, respiratory rate, oxygen saturation, temperature, and weight. For 30 days, patients took daily biophysical measurements and wound photographs and interacted with nurses virtually. In the standard-care group, patients received post-hospital discharge management according to their centre’s usual care.

Primary outcome: Days alive at home.

Secondary outcomes:

  • Acute-hospital care
  • Detection and correction of medication errors
  • Pain at 7, 15, and 30 days after randomisation.

Virtual care with RAM shows promise in improving both outcomes important to patients and to optimal health system function.
