This observational study aims to examine outcomes of home-based acute care delivered by a mobile healthcare team in persons aged 75 years and older following an episode of acute illness.

The study will assess whether home-based acute care initiated by the emergency medical dispatch centre or ambulance services is non-inferior to emergency department care with regard to care needs and mortality.

Inclusion Criteria:

• Contact with the emergency number (112), followed by either a telephone assessment by the Emergency Medical Dispatch Centre or an in-home assessment by an ambulance nurse
• Home-based acute care a weekday between 8 AM - 4 PM
• Emergency-department care weeknight 4 PM - 8 AM or weekends
• Registered residence in one of the municipalities of Gothenburg, Mölndal, Partille, or Härryda

Exclusion Criteria:

• Immediate conditions requiring hospital care
• Care at the emergency department or by a mobile primary care team occurring more than 24 hours after assessment by the Emergency Medical Dispatch Centre or ambulance services
• Individuals who have already been assessed by a physician and/or have a written referral to the emergency department

The study population consists of persons aged 75 years and older with an acute illness who contact the emergency number (112) and are assessed by the Emergency Medical Dispatch Centre or ambulance services, and who subsequently receive either home-based acute care from a mobile healthcare team or care at the emergency department.

Individual participant data will not be made publicly available due to privacy and legal restrictions.
