Medical staff work long shifts with short breaks. Coffee has to be available fast and at any hour.
Medical staff are best served by coffee in a staff room or employee area, away from patient spaces, from a device that is available around the clock and serves drinks quickly. Short breaks on duty mean every minute counts.
Where to put the device
In the staff room or near the nurses' station, in an area open only to staff. The page on vending in hospitals (publisher's site) describes such setups.
Speed and availability
The device should serve drinks fast and work at night too. Restock to match the duty schedule.
Hygiene
Healthcare facilities have internal hygiene rules. Agree with the responsible department how the coffee area is cleaned.
FAQ
Can the machine be in a patient corridor? That is a separate matter. A staff machine is best placed in an employee area.
Who restocks at night? Usually it is restocked before the night, on schedule.
