Iatrogenic Effect? Cautions when Utilizing an Early Health Education for Post-concussion Symptoms

Abstract

Objective Patients with mild traumatic brain injury (MTBI) usually suffer from the post-concussion symptoms (PCS). PCS could recover by 3 months post-injury, but some patients still persistently complain of those symptoms for years. Accordingly, the Chang-Gung University Brief Intervention for Post-Concussion Symptoms (CGU-BIPCS) was developed to intervene PCS based on the established advantages of health education. This prospective study thus aims to evaluate the effectiveness of CGU-BIPCS for patients with MTBI. Methods A total of 130 participants, which included 53 healthy participants and 77 patients with MTBI. Patients were further subdivided as two groups: "regular intervention" (RI) and "health education intervention" (EI). PCS of patients with MTBI were respectively evaluated at 2 weeks and 3 months post-injury, and symptoms of healthy participants were also examined. Results Both patients in RI and EI reported significantly more PCS than healthy participants did at 2 weeks and 3 months post-injury but less PCS at 3 months than at 2 weeks post-injury. However, the PCS endorsement of patients in RI and EI were not significantly different. In addition, more patients in EI reported significantly PCS deterioration than patients in RI did at 3 months post-injury. Conclusions Although establishing the effectiveness of CGU-BIPCS was unsuccessful in this study, it is further suggested that a potential iatrogenic effect from this kind of early interventions should never be overlooked.
