The dual-handset allows the patient to speak into one handset, the clinician to speak into the second handset, and the professional interpreter (vendor-based or in-house staff) to facilitate the conversation from a remote location. Before the intervention, up to three dual-handset interpreter telephones were available on most units, located on mobile carts, and kept at the nursing station or in locked cabinets until needed.
In-person professional interpreters could be scheduled during weekdays (8 am to 5 pm) before and throughout the intervention period.
