Primary Care Utilization and Prehospital Emergency Demand Among Patients with Multimorbidity in Spain.

In multimorbid adults, prehospital emergencies demand is influenced by factors beyond severity, including comorbidities, polypharmacy, the use of home medical devices, caregiver availability, and primary health care utilization patterns.

Strengthening coordination between prehospital emergencies and primary health care, promoting patient-caregiver education, and implementing early notification pathways may improve care continuity and reduce avoidable emergencies.
