Measuring Patient-Reported Outcomes Following Traumatic Craniomaxillofacial Injuries: Development of the AO CMF Injury Symptom Battery

Background/Objectives: Traumatic craniomaxillofacial (CMF) injuries are associated with various symptoms/concerns that affect patients' quality of life. The assessment of outcomes from the patient perspective has been limited by the absence of patient-reported outcome (PRO) measures tailored to this patient population. To address this need, we employed a mixed methods, multi-step process to first identify the most important symptoms/concerns and then use this information to construct a PRO symptom battery. Methods: CMF clinicians and patients who had sustained traumatic CMF injuries participated in semi-structured interviews to elicit the symptoms/concerns considered the most important. The data were analyzed using an iterative coding procedure and symptom/concern frequency was tabulated. The findings were used to develop a conceptual model of the most important symptoms to include in a PRO battery. Existing items were modified as needed and new items were drafted to ensure adequate coverage of the symptoms. Results: The resulting AO CMF Injury Symptom Battery includes four modules specific to the injury site (oral, ocular, nasopharyngeal, ear) and five universal modules (pain/sensation, cognitive, cosmetic, psychosocial, and injury impact). Conclusions: The AO CMF Injury Symptom Battery offers promise for assessing symptoms only patients can report on in clinical research and practice. Ongoing research will examine the battery's psychometric properties.
