Primary care has been viewed as a means to ensure equitable access to care, enhance efficiency within healthcare systems, and improve health service quality. In recent decades, Iraq has transformed its compromised health system, shifting the healthcare model from hospital-based to primary care through primary health centers (PHCs) and referral mechanisms. Based on an extensive literature review, this qualitative paper explores the healthcare utilization of PHCs in different regions of Iraq. It also identifies some barriers to PHC use and recommends evidence-based approaches for improving PHCs' performance. Some reported challenges to better utilizing PHCs were the poor quality of services, patient dissatisfaction, long walking distance to a health center, and limited availability and affordability of the medications. If Iraq is to use primary care as a tool in achieving sustainable development goals (SDGs), collaborative efforts addressing the facility-related factors should be a priority.
