Keep a current medication list on the refrigerator, including doses and prescribing providers. It saves critical minutes in an emergency.
Program emergency contacts into the phone and post them in large print near it.
Test smoke and carbon monoxide detectors twice a year, and check that the water heater is set below 120°F to prevent scald injuries.
Set up a daily check-in, whether a call, a text, or a scheduled caregiver visit, so nothing goes unnoticed for long.
