Brief summary

A single center prospective before-and-after proof-of-concept study to evaluate a telemedicine center for the PACU.

Detailed description

A proof-of-concept study in perioperative telemedicine that aims to demonstrate the (i) acceptability and (ii) utility of integrating telemedicine into the PACU environment. This proof-of-concept study will be conducted in the PACU.

Observation Phase
In the first three months of this proof-of-concept study, a telemedicine center for the PACU will monitor patients assigned to PACU bays. Both telemedicine center clinicians and nurses caring for patients in these PACU bays will independently record information on patient physiological derangements, treatable symptoms, situations requiring urgent medical intervention, and discharge readiness (based on the modified Aldrete scale). During this phase of the study, clinicians in the telemedicine center will not communicate with clinicians in the PACU (nurses or physicians), unless there was a patient safety event.
304
Interaction Phase
In the three months following the observation phase, clinicians in the telemedicine center will interact with clinicians and patients in the two designated PACU bays using audio-visual technology. The clinicians in the telemedicine center will continue to document information on physiological derangements, treatable symptoms, situations requiring urgent medical intervention, and discharge readiness.
