Background: Endotracheal tube (ETT) fasteners such as the AnchorFast™ claim to assist with the prevention of oral pressure injuries in intubated patients, however evidence to support their clinical efficacy is limited. This retrospective observational study aimed to investigate the impact of the introduction of the AnchorFast™ device on the incidence of oral pressure injuries in mechanically ventilated patients. Methods: Data was collected from patient case notes and clinical incident reports for October 2010 to June 2013 (pre-AnchorFast) and July 2013 to March 2016 (post-AnchorFast). Incidence and location of oral pressure injuries associated with securing device, and compliance with institutional policies related to reducing oral pressure injuries were recorded. Results: Incidence of oral pressure injuries increased from 1.53/100 intubated patients in the pre-AnchorFast period to 3.73/100 intubated patients in the post-AnchorFast period (IRR = 2.43, 95%CI = 1.35-4.38; p = 0.003). Across both study periods, patients with an ETT secured using AnchorFast™ had significantly increased risk of oral pressure injuries (IRR = 2.03, 95%CI = 1.17-3.51; p = 0.02). There was also a significant difference in location of pressure injuries sustained with ETTs secured using cloth tapes (53.6% in corner of the mouth) vs. AnchorFast™ (75% on the lips) (p = 0.008). Among patients with oral pressure injuries, compliance with institutional policies relating to the prevention of pressure injuries was significantly greater after the introduction of the AnchorFast™ (9.1% vs 64.5%, p = 0.004). Conclusions: The incidence of oral pressure injuries increased significantly following the introduction of the AnchorFast™ device. Further research is required to establish the reasons for this observed increase to and identify ways to reduce the risk of pressure injuries with ETT securement devices.
