OBJECTIVE: To explore the association between psychiatric disorders as a comorbidity and return-to-work (RTW) in individuals with acquired brain injury (ABI).
METHODS: A systematic review was performed. The search strategy (2002-2012) contained terms related to ABI, psychiatric comorbidity and keywords adapted to the outcome measure RTW. Selection and review were performed by two authors independently. In the case of uncertainty, a third author was consulted to reach consensus on inclusion or exclusion. The methodological quality of included studies was determined and evidence was classified.
RESULTS: Seven studies were included. Strong evidence was found for a negative association between psychiatric disorders as a comorbidity (like depression, anxiety and post-traumatic stress disorder) and RTW of patients with ABI. Patients with a previous history of psychiatric disorders were at considerably higher risk for a new episode and lower RTW rates following ABI.
CONCLUSION and implications: Psychiatric disorders as a comorbidity after ABI are strong negatively associated with RTW. The heightened frequency of psychiatric disorders as a comorbidity after ABI and more important their amenability to treatment implicates that more attention should be paid to diagnosing and treating psychiatric disorders as a comorbidity in patients with ABI in order to further improve re-integration in work.
