Patterns and predictors of dental hospitalizations in patients with acquired brain injury from pre-injury to acute and post-acute injury.

BACKGROUND

Acquired brain injury (ABI) can cause long-term disability and functional impairment.

OBJECTIVE

This study aims to determine the prevalence of dental hospitalizations in an ABI cohort across different phases of injury and identify factors associated with such hospitalizations.

METHODS

The cohort comprises patients with ABI (n = 683), traumatic (n = 282) and non-traumatic (n = 401) who were admitted to a neurorehabilitation service in Western Australia between 1991 and 2016. De-identified patient data were linked to the Hospital Morbidity Data Collection. The incidence of dental hospitalizations was calculated per 1,000 person-years (PY), and associated factors were investigated using multilevel mixed-effects logistic regression.

RESULTS

Dental hospitalizations significantly increased from pre-injury (3.35/1,000PY) to acute injury (302.65, Δ+299.3) and remained elevated in the post-acute phase (23.98, Δ+20.63). Dental caries had the highest incidence rate among all diagnoses in the pre-injury and post-acute phases (0.68 and 8.93, respectively), followed by gingivitis and periodontal diseases (3.60) in the post-acute phase. Tooth extractions were performed more often than restorative and preventive treatment in the pre-and post-injury phase, p < 0.001. Dental hospitalizations were associated with the type of ABI, age at injury, remoteness, and history of pre-injury hospitalization.

CONCLUSION

Implementing comprehensive preventive dental care can reduce potentially preventable dental hospitalization among ABI patients.
