How will robots change the role of human caregivers in patient support?

Question

Accepted Answer

Robots like Alter-Ego are expected to shift human caregivers toward companionship by taking on some repetitive support tasks in hospital wards

A hospital in Milan is running a trial of a 1.2m robot, Alter-Ego, that performs basic tasks intended to free up healthcare workers. The robot can stand in for a doctor working remotely, bring a patient a bottle of water, guide them to treatment, and collect patient data such as pain levels that are sent instantly to ward nurses. The project is designed to test the limits of what robots can do in a hospital setting, with a view that robots may later support patients and caregivers at home.
Alter-Ego takes on specific ward tasks while nurses remain in charge
Alter-Ego is being tested since April in a department treating amyotrophic lateral sclerosis (ALS), and it is currently remotely controlled by an operator. The plan is for the robot to work autonomously from July, but its data collection is tied to human oversight: pain levels shown on a screen attached to the robot’s chest are transmitted instantly to nurses. In parallel, nurses continue to monitor patients while handing out medicine and watching for signals about physical or mental health.
Caregiver time may shift away from routine duties toward human relationship work
The hospital partners aim to understand what a robot can or should do in a hospital ward, including how it affects day-to-day caregiving. Hospital staff point to the presence of repetitive tasks that could be delegated to a “good robot,” which would allow staff to spend more time on the human relationship they must maintain with the patient. Within the ALS context, neurologist Rachele Piras said Alter-Ego may still be useful in other ways as the disease progresses, even though direct delegation of tasks like administering pills has not been considered.
Patients may use the robot as a direct point of contact for requests
Alter-Ego can speak to patients in real time, asking whether they need anything, and it can guide them to treatment. A 31-year-old patient, Daniel Senna, demonstrated how he transmits his pain level to the robot, while the robot communicates with him and sends the collected information to the ward nurses. The project also frames the robot as something patients can directly ask for help with certain needs, which is described as potentially “liberating” for patients.
The trial is also focused on the boundary between robot support and human care
The robot is being used to explore limits rather than to replace human roles outright, with testing beginning in April and autonomy planned from July. Researchers and clinicians emphasise that not all caregiving tasks are treated as suitable for delegation, with the example that no one had considered delegating pill administration to the robot. The broader goal is to reduce caregiver workload for particular repetitive duties so caregivers can focus more on companionship, described as reverting to roles such as “a companion, mother or daughter.”
