Abstract Background The Emergency Medical Communication Center (EMCC) plays a vital role in the medical emergency response system by triaging contacts, notifying local physicians, and providing medical advice. The utilization of acute care services and the subsequent care pathway by individuals with immigrant background remains unclear in the Norwegian context. This study aims to investigate whether disparities exist in the acute care pathway for patients with different sociodemographic background who use ambulance services. Methods We examined all code red ambulance dispatches for life-threatening emergencies in 2021 in Norway. These ambulance dispatches were linked to primary health care and specialist health care contacts to trace patient pathways and outcomes. Statistical analyses were conducted using linear regression models, adjusted for patient characteristics, such as immigrant background, age, sex, municipality of residence, living condition, socioeconomic status, comorbidity and cause of emergency contact. Results Preliminary crude findings indicate that patients with immigrant background are overrepresented in the groups receiving acute primary care only and underrepresented in the groups transferred directly to specialist health care, within 8 hours after ambulance arrival at the patients’ location. Conclusions The preliminary results suggest challenges for the EMCC in triaging patients with immigrant background, but further research is needed to explore potential systematic differences. This study aims to improve understanding of disparities in access to acute care and inform targeted interventions to optimize resource allocation in emergency departments. Key messages • This study may improve understanding of disparities in access to acute care in Norway. • This study can inform targeted interventions to improve resource allocation in emergency departments.
