Referral Patterns from Primary to Tertiary Oral and Maxillofacial Surgery Units in Bauchi State

An efficient patient referral system is fundamental to delivering timely and appropriate oral surgical care within a hierarchical healthcare structure. In Nigeria's North East geopolitical zone, referral pathways for maxillofacial surgical cases from primary to tertiary care are poorly characterized, leading to delays in management and disease progression. This retrospective descriptive study analyzes the referral patterns of patients transferred to the Oral and Maxillofacial Surgery unit of Abubakar Tafawa Balewa University Teaching Hospital (ATBUTH), Bauchi, from primary and secondary health facilities in Bauchi State, over a three-year period from 2021 to 2023. Referral letters, clinical records, and patient intake registers were reviewed for 140 referred patients. Data collected include referring facility type, diagnosis at referral, appropriateness of referral, time from onset of complaint to arrival at the tertiary center, and reason for referral. Results indicate that 67% of referrals were deemed appropriate based on case complexity, while 33% involved conditions manageable at the referring facility level. A median delay of 12 days from symptom onset to tertiary care arrival was noted. Mandibular fractures and space infections were the most common referral diagnoses. The study identifies gaps in referral training and communication protocols at lower facility levels and recommends the development of clear referral criteria guidelines for oral surgical emergencies across Bauchi State.
