Word choice for a health-monitoring app: patients, clients, dependents, other?

I'm designing the UX for a healthcare app, to help carers remotely monitor elderly patients.

The word currently being used (in the prototype) to describe the elderly is "dependents" but it has negative connotations

Is there a better word to refer to them?

The primary target audience for the app is professional carers, however they're not doctors, so I'm not sure that "patients" is the right word, and "clients" feels a little cold.

To make things extra complicated, the secondary target audience for using the app is loved ones or family members.
